hi folks lately we've seen a lot of
impressive improvements from Tesla's
autopilot system one of the major
components of this system is the radar
and because of this radar sensor working
impressive accident avoidance and driver
assistance features we got traffic where
cruise control autopilot
collision-avoidance a pedestrian
avoidance unfortunately zombie avoidance
but that's easily manually overridden by
a sliding on the accelerator whole
different topic anyways I thought we
could dig a little bit deeper into this
radar piece of hardware which is a
amazing tiny piece of hardware that at
that one of my viewers was able to dig
up the Boche manufacturers features in
specs paper so let's take a look at this
critical component i got four pages i
have written note this was a little bit
of a research project for me and that I
learned a lot
so let's dig it dig into it the sensor
is manufactured by Bosh Bosh also offers
a scalable design and can modify the
hardware to suit the needs of the
specific met vehicle manufacturer and
the vehicle requirements because Bosh is
able to tailor the sensor to the auto
manufacturers specs which of course
Tesla most definitely has had some
changes done and of course we also lack
information on what those changes might
may have been
by Tesla we're just going to have to go
based on the publish documentation from
Bosh and one thing although this call
touched on this a little further
one thing I can tell you is testable
claims of distance that the vehicle can
see is considerably further by about 90
meters compared to what box claims are
well touch on that at the end closer to
the end so let's hit up the stock
information here one of the sensors of
multimodal with four independent
received channels and dim digital
beamforming multimodal means that it
varies range and resolution depending on
the target be informing means it is
designed to detect objects within a
certain range digital being forming is
the amplitude phase variation is applied
to signal after analog downconverter /
digital down conversion the received
signals from the antennas are first
passed from the ADC and DC before
summation of the operation being forming
is used for directional signal
transmission and reception it has the
ability to change both the amplitude and
phase with helps that has the ability to
change both amplitude and phase with and
helps with power variation as well as
being steering in the dirt desired
direction
ok let's see what you got
my handwriting was crap so i retyped
everything up
oh my bullet points and notes i got a
lot of them here summed up this all
allows the sensor to be configured into
pit with independent antenna for
different directions improved accuracy
and adjustable field of view depending
on the situation by focusing the radar
at a narrow main lobe with angle of plus
or minus 6 degrees the system can react
two vehicles of long-range and perform
well at higher speeds as well as
maximize interference
excuse me as well minimize interference
from vehicles in adjacent lanes so think
of that as being like okay
autopilot or traffic where cruise
control you're in a clustered situation
you got lots of vehicles around you by
focusing the radar think of it like
focusing flashlight you can zero in on a
specific section or object or in this
case the lane directly in front of you
it helps keep the vehicles on the side
out of that field of view that's
directly in front of you so it doesn't
interfere basically okiya help you keep
proper distance and react quicker to
what's directly in front of the vehicle
the elevation antenna has a plus with a
plus or minus plus minus 42 degree
opening achieves a close-range detection
zone capable of detecting a pedestrian
stepping out onto the road from behind a
parked car as as example as a early
stage of detection due to the high level
of integration of sensor control
functionalities Josh was able to achieve
compact design allowing he's a placement
within a really wide range
a vehicle design so first gen autopilot
it was a sensor on the bottom of the
bumper nothing too special about that
then they realized okay that placement
really kind of sucks gets a lot of slush
snow there so they moved it up and now
it is actually behind the t emblem the
intestinal insignia on the front bumper
of the Refresh design model s cars and
of course behind the tea on the X and
most likely who sees me behind the tea
on the model 3 equipped with a
self-calibration system the sensor
searches for reference points and first
journey and calculates sensor access
deviation from dynamic driving access
axis not access but axis access
there was a system software compensates
for this deviation during learning phase
some features or functions may be
disabled until complete you'll mostly
see this metric house how working out
with autopilot two point oh I with the
autonomous hardware but in autopilot one
point I know when my vehicle was
delivered pretty much deal well no
autopilot in cruise control did work
however a lot of the parking features
and other miscellaneous things i had a
pop-up warning seeing these are not
quite ready yet system is still being
calibrated while blog just as example
and at one point this past summer the
system had to be recalibrated now it's
self-calibration system not automatic
calibration system so when my system had
to be recalibrated actually had to have
service go in and they read set and then
they actually took the car and drove it
back and forth on the freeway in some
city streets a number of times to
recalibrate it
solid-state components or in other words
no mechanical moving parts allows the
unit to have a high tolerance for
vibration that's a plus on wisconsin
specifically Milwaukee roads where we
have summer no excuse me you have winter
then we have a pothole season and then
road construction season
the radar also has radome radome heating
available of which my investigation show
Tesla to have chosen based on my thermal
imagery you can see that video under my
account
radon heating allows the unit to melt
off slush ice and snow that is in direct
contact with the radar sensor so that
build-up unfortunately if it melts out
little cavern can only melt what really
what's physically touching it
so then you got a little cavern of slow
snow slush and ice and you can lose
access to the radar anyways which was a
major one of the major reasons they
raise the center of Tesla raised the
sensor up higher
it's about a foot higher and the
refreshed Model S's than it was on the
original styling the radar uses
frequency band of 76 277 gigahertz due
to triple carrier frequency at 77
gigahertz the sensor only needs one
third of the antenna surface of the
other older existing 24 gigahertz
sensors to cover the same field of view
at the same resolution benefits of this
means significantly smaller allows
measuring speed based on the Doppler
effect which results in three times more
accuracy than the older 24 gigahertz
style units
this allows sensor to intervene at an
earlier stage to reduce speed in
critical situations operation the radar
is designed to detect objects and
measure their speed and position
relative to the movement of the vehicle
which it is fitted to do this one the
radar sends out a wave in the 676 277
gigahertz range via transmission and
tennis two waves are reflected by
objects in front of the video
well relative speed and distance between
the vehicle and other objects is
determined based on the Doppler effect
and the delay frequency shifts between
the sent and received signals are
generated and comparing the amplitude
and faces of the radar signal measured
by the for antenna it is possible to
infer the position of the object
what is the Doppler effect the Doppler
effect is an increase or decrease in
frequency of the radar as the source and
observer move to oral way from each
other
this causes a sudden change in pitch as
example I think fire truck coming
towards you with its siren blasting we
then as it's going ok I guess I really
don't need to do the sound effects so
anyways as the fire truck with its iron
blasting comes towards you the pitch
goes up and then as its driving away the
pitch goes down say they happened with
radar elevation antenna can generate an
additional upward elevation being
allowing the sensor to measure height of
all detective objects to help reliably
classify relevant objects and determine
if a vehicle can drive under or over
them special signal processing
algorithms are used this allows the
system to cope with complex traffic
sexual situations and break more
reliably even in the case of stationary
objects predictive emergency braking is
also available if peb determines the
distance of the preceding vehicle is
becoming critically short at a vehicle
speed above 18 miles per hour hence the
18 mile per hour speed been made
mom for traffic where cruise control and
autopilot it will reap it will prepare
the vehicle for potential emergency
braking if the driver does not react
the system uses audible visual warnings
followed by a short jerk of the brakes
this system initiates partial breaking
and if driver also applies breaks it
will calculate the pressure required to
stop and apply additional force to avoid
collision if peb detects unavoidable
collision and operator does not
intervene it can initiate full braking
that test that
thank you Mike Anthony if collision is
unavoidable even with a eb it will do
its best to mitigate the severity of the
collision the sensor is capable of
supporting traffic workers control up to
93 miles per hour 150 kph and intestines
case also autopilot with a max relative
speed of 50 miles per hour or 80 kph and
works in stop-and-go environments if in
case you're not understanding what
relative speed means ok think of it I'm
going down the freeway at 60 mount 60
miles per hour and a vehicle passes me
going 65 so even though i'm traveling 60
he's traveling 65 are relative speed my
speed in relation to the other vehicle
is a five mile per hour difference so
we're traveling five miles per hour
relative or think of it a two-lane
highway country highway i'm driving 50
the person coming from the other
directions driving 50 as we pass each
other are relative speed is actually 100
miles per hour for each traveling then
away from each other at 100 miles per
hour
I don't think I explain that last one
quite right you get the idea
heading distance indicator can warn the
driver if safe following distance is not
being maintained the units also
incorporate sensor data fusion here's
where a whole bunch of magic happens
they're after me lucky charms wrong
serial sorry sensor data fusion combines
the benefits of different sensors and
measuring principles in the most
effective way possible providing data
that individual sensors working on their
own would be unable to generate this
fusion increases the measurement range
reliability and accuracy video sensors
along with software algorithms are data
fuse with the radar in Tesla autopilot
without the camera car cannot do
autopilot without the radar Crocker to
autopilot needs both and the data fused
together in put it by both to be able to
do autopilot and not kill anybody
this fusion also allows for automatic
emergency braking with pedestrian
protection now
Tesla has been updating software in
really starting to activate incorporate
more and more of these features into
their system actually they're all there
it's just now their programming them to
all work in synchronous asynchronous
synchronicity close enough
one example of this is i recently posted
a video showing my car driving down a
road that had no lines autopilot was in
fact active and doing all the steering
and all the hard work it was using a
combination of the radar the autopilot
camera and the 12 sensors sonar sensors
surrounding the vehicle in order to
maintain a radar Elaine in order to
maintain driving in its Lane even
without those lines on the road you
previously to Tesla activating these
features which is don't do that i was
testing things out
don't do that prior to this that would
have not have made possible so Tesla has
really started incorporating not just
this fusion of data between all the
sensors and program programming that
into the autopilot system but this
fusion is also gonna be incorporating
data from the GPS sensor and the fleet
learning and just mashing it altogether
uses as much of that as it can to to
control the vehicle every extra little
bit of data it can
helps so let's just go over Josh
statement of customer fat benefits one
digital beamforming two independent mode
for height measurements three
cost-effective design for tailored
solutions five self-calibration 6 can be
concealed behind the bumper seven no
moving parts
aight sensor data fusion nine small size
10 high speed and flex relay enter can
in flex really interfaces and 1176 277
gigahertz that covers be sense are the
Tesla radar sensor and as long as we got
it i'm gonna have all this in the
description box below so it's easier for
you guys to reference and access and as
long as we got it using all recycled
paper you know
no throw stuff away print on the back
side then recycle it
the technical features now a Boche has
available both a forward-facing and
rear-facing radar device radar sensor i
am only talking to be talking about the
and have only been talking about the
forward-facing I left out for the
rear-facing because as of right now
Tesla does not use the rear-facing radar
not in current autopilot 1 point 0
matin autopilot 2 point 0 as far as what
we're aware even autopilot on the model
3 and model x do not use the rear radar
only front-facing so frequency range 76
277 gigahertz detection range point 3 6
260 meters so there's that hundred and
sixty meters
that box states and i believe i read
that Tesla systems can see seen up to
250 meters so that is a 90 meter
difference now as i just read with the
with the the fusion data fusion sensor
data fusion how it can change the many
jobs uh combines different sensors and
measuring principles and the most
effective way now this is radar only can
see if 260 meters but it's quite
possible if you combine both the radar
and the camera together the autopilot
camera that you could get that further
distance of sight from the radar or from
the system feel the view horizontal main
antenna plus or minus 6 degrees provides
a hundred and 60 meter distance viewing
distance plus or minus 90 degree gives a
100-meter viewing distance and plus or
minus 10 degrees gives 860 meter fuel of
you are viewing distance elevation
antenna plus or minus 25 degrees gives a
36 meter plus or minus forty-two degrees
gives you 12 meter measuring accuracy
distance point 12 meters for speed
accuracy is point 11 meters per second
and angle accuracy is 0.3 degrees plus
or minus object separation capability
distance point seven two metres speed
points66 m/s and angle seven degrees the
cycle time
maximum or the fastest cycle time is 60
milliseconds so I'm going to touch on
that real quick and interject here that
means was my and then the calculator
let's see
so
so according to Bosh the radar sensor to
actually refresh and take a sample every
60 milliseconds that means it's actually
capable of sixteen point six seven
refreshes per second in firmware 8
according to Tesla firmware 8 has bumped
up the refresh rate from the radar 210
refresh rate 10 Ryo 10 times per second
so that's 100 milliseconds so it looks
like Tesla still has a considerable
amount of room to go that they could
increase the Refresh speed is low as 60
milliseconds i have just to interject
again my thoughts on why they may not
have done this on the one point or cards
with firmware eight might be just the
sheer processing power in these systems
these are all tegra3 systems now the
autopilot two-point old cars have
computer systems the Frankie forget the
exact model by Nvidia but they are
approximately 40 times faster than the
autopilot 1.0 and classic models
computer systems that is fast and that's
all for fully autonomous driving so it's
quite possible Tesla might use more of
that data from the radar in the future
and that will add another 6.7 frames for
per second of data of radar data has
frequency modulation FM CW there's
another 1 i'm going to interject done
max number of detected objects is 32
sorry trigger guide to the galaxy fans
it's not 42 apparently the magic numbers
32 now from where seven with autopilot
and I i went back in when firmware it
was released I touched on this now I
always knew and firm or seven that the
radar would see a maximum about 55 other
vehicles on the road at one time for the
release notes of press release of
firmware eight Tesla said they bumped
that up by five fold so 5 10 15 20 25
wasn't six-fold they bumped up 5464 they
said they bumped it up somehow I think
you'll see the five or six fold and
whatever it was my guesstimation was
that a Model S's radar community tech
approximately thirty objects at a time
that was back that was before I knew
anything about this based on previous
calculations and observations with the
car so it looks like i was only two
objects off once again though customized
radar
how could be processing power we don't
know because Tesla will not tell us or
release that information see weight of
the sensors a hundred 90 grams always
practically nothing
and here is the amazing one it does so
so much with only 4.5 watt power
consumption so it is extremely
energy-efficient now i don't know if
that 4.5 what does or does not also
incorporate the power consumption for
the radio meeting my guess is no
eating generally is going to take a
considerable amount of power and yeah
that's quite a bit there so I'm that is
it
I I know this one is the long one
30-minute video here and it was long
probably boring but if you're someone
who was interested in learning about the
radar systems that Tesla was using hope
I was able to teach us something

3 THINGS I KNOW TO BE TRUE - Duration: 5:09.
Well, because today is the first day of the year and
and it's a time for renewal,
time to do something new, I've decided to
do something quite different here on my channel,
so I'm in my closet...
Don't worry, I won't give you a tour of my closet,
but it's an intimate place to
talk about intimate subjects,
so today I'll answer the TAG that I
just created which is about
"3 things I know to be true" because I think
we often end up
sharing unimportant
things on social media,
so today I decided to share with
you three ideas that are important
to me and that I know to be true.
I hope you like it :)
Well, the first thing I know
to be true is that just like we
need to take a shower to clean
our body,
we also accumulate mental
dirt,
so we also need to clean up our
minds once in a while. And there are many
ways to do that, but one thing
that has been helping me a lot and that I think
works rather well
is meditation. I want to
make a more specific video about
meditation soon because I believe
meditation helps in all
aspects of life.
The second thing I know to be
true is that all of us live inside
a bubble.
Some live inside a very small
bubble, very tight, almost suffocating.
Others live inside a bigger
bubble, but all of us live
inside a bubble which is our immediate
reality. And this bubble ends up really
limiting us, limiting our way of
thinking, limiting our way of living,
so I believe that it's very
important to seek out situations and
seek out experiences that make us
get out of this bubble.
And, at least for me, two things that are
very effective and that make me burst this
bubble of mine is traveling and learning new
languages, that's why I talk a lot
about these topics here on my channel. But
there are many other ways as well,
such as reading books out of our area of
interest, out of the subjects we
usually read. And in doing that
we end up really widening...
our reality, widening the possibilities,
widening our horizon, so
this is my second truth.
The third thing I know to be true
is the material goods, things,
pants...flip flops, shoes, bags,
these things don't bring us happiness.
I think that after that first excitment
of having bought something new,
things really don't lead to happiness.
In order to compensate for our lack of
happiness or meaning, we often
consume way more than we should and that
doesn't lead us anywhere,
but I think that nowadays there are so many
messages of consumerism on social media,
especially on Instagram, on
YouTube that we often end up being
swallowed by them and end up going with
the flow without really thinking.
The fashion industry is one of the largest
polluter in the world. It's kind of
crazy the amount of things we
consume
and it's an appeal to our weakness of trying to find happiness
in material goods or wanting
luxury goods to look chic or to
belong to a certain group
and this...I know it doesn't bring happiness,
so this is the third thing I
would like to share with you and I think
it's kind of crazy, right?, that I have to say
this or that I'm saying this, but I
see so many...so many people seeking happiness in
material goods that I think it's important
to say it and to leave this out there.
Well guys, those were my 3 truths. If
you have a blog or if you have a
YouTube channel and you'd like to
participate in this TAG and share with
us "3 things you know to be true,"
answer the TAG and then send me
the link so I can check it out. And if you
don't have a YouTube channel or if you don't have
a blog, leave a comment below
with 3 things you know to be
true. It doesn't have to be very
serious or profound, it can be
anything you firmly believe
is true so we can
start the year learning things that are
interesting and important with each other.
I hope you have enjoyed
this video, I know it's a little
different from what I usually do, but I
thought it was important to do it, this idea came to my
mind, so I hope you have
enjoyed it.
And I hope that in 2017 we all
live more closely aligned
to our truths.
So, xoxo
and I'll see you next week :)

Disaster broken glass in kitchen Cooking Stovetop #1898 - Duration: 3:47.
hello guys happy new year okay we had a
disaster yesterday today is the first
and i'm going to show you what happened
we had a big disaster and ended up with
a broken stove so i'm going to show you
the broken stove first there it is you
see that
ok so this is what happened we've got a
ninja and we love a ninja we were making
juice okay i'll show you the juice the
juicing that we've been doing in the
refrigerator here so there's the juicer
back there and so my husband's making
the juice i'll show you this too
ok so the back part here the lid doesn't
stay down anymore and so I don't know
what that's like the whole carriage part
that's broken but anyway the whole the
lid doesn't stay down
so this is what he did so go over here
and we get this so he's got this pulled
out right about here and it's so it's
sitting up here and it fell down and
went wack right on the stove and so I'm
in the other room and all I hear is oh
shit and so and I'm sitting there
thinking what happened because I'm
concerned that he cut himself so the
last time also the knives see here some
lives we got some knives right here and
one of them is missing because he didn't
like it and he cut himself really really
bad with this was about 4 or 5 years ago and
so he was getting ready to go on a new
job and he cut his finger like bad it
had to have stitches and so he had
missed his first day of work which was
terrible but you know accidents happen
you can't plan on accidents happening
and so anyway I thought he cut himself
and so with him be having these blood
clots and the blood thinners and
everything and you know and so my
concern is if you start bleeding his
blood is
in and then he you know he could bleed
to death you know something really
catastrophic was happening and so I
hollered at him i said what's wrong and
so I just SAT still for a minute or two
he's not answering me and so I get up
and he finally says here not going to
believe what happened a minute or two
might be too long but maybe maybe 15 to
30 seconds you're not going to believe
what happened and I'm like you cut
yourself
he's like no worse and so I come out
here and then this is what I see and I
said well I don't think that is worse
you know because my thing is him cutting
himself would have been worse i mean
yeah granted we need a new stove now
because this isn't going to work and I
know he's probably going to want to try
using it still but i'm thinking with the
heat this could actually crack at worse
maybe it could make the whole thing
explode
I don't know but that's just my thinking
is you know that that could possibly
happen let's get a good look down there
maybe I should find you i have a light
let me see me let me pause you guys
for a second I'm gonna pause you guys
oh gosh I don't think I paused you okay
this going to pause you guys here first

We Happy Few Part 2 - HIGH ON MUSHROOMS!!!!! - Duration: 12:49.
We Happy Few
having a great day and I wish you all I
happy new year
welcome back to we happy few now in the
last episode we got stung to death by
piece
we got some honey and we came to this
store gave its adbusters over there
pure water so i have some that I can
spare at least know I only have one and
I'm already dying
I need some help so for this episode I
have no idea what to do so let's just
check out the math real quick
this is where i had to go in the last
episode
well at least that's what the game told
you I kind of went around so i'm going
to go back there from the other side and
see what's up
alright let's go i also need some help
so I'm going to go am I going the right
way
no I'm not I'm so stupid i'm going to go
over here in the outskirts because I
needed somebody's to make some here in
bham and hear myself I got here myself
to it
we're also gonna die you're not going to
have any gameplay
Oh some water okay this is good do I
have any empty canteens okay now hold on
oh now i have to let's go back and find
a dude because I feel bad for yelling at
him and everything going to give him
some water if you're still here
did we are you okay there you are now
it's not you it's not you
the holiday go what does anyone need
water
hi hello me some water
99 you just scared me ok here's
something you don't want any okay
the fuck is he that him now it's not he
was wearing a hat alright guess he's
gone
I mean I wanted to get in the water but
guess he wasn't there for it
what is this this another hatch i can
get in
ok real he was no house for me it's way
better than the other one and i have
some pedals
wow that is so cool okay i think i can
make my dad even bomb right now okay
crafting menu or is it there we go
use and use ok we are doing great and I

Sprint 3: Scrum based project building a web app in 8 weeks. - Duration: 9:21.
hello and welcome to the sprint 3 demo
for my web app project
let's get into this by having the
product backlog. so i'm going to share my
screen
hopefully the image does actually appear
on the bottom right-hand side
I've had a little bit of trouble, I could
say a little bit with Zoom
but it's been quite a lot, I've had to re-record
these sessions several times just because the
screen just gets messed up it doesn't
like VM images and you can see that i
have the 2 start menu's on the left-hand
side, task bars as we call them, and, so
this print it was about fixing a couple of
bugs and the logout button didn't work and we
also had unauthorized access going on
the next one was the web service, so, the
logout button quite quick
login button, it shows us the pop-up and
it goes to google gets your access and
takes you back to the site, that's about
it. you see it's not transitioning into
this tasks list just yet, i will get that
the access part, we logout again, we could
just give that a quick try by typing in
tasks and seeing what happens
nothing should happen
exactly. it did try to get it, but it has
not i access, so that's that part of the
demo. so the web service was quite an
interesting thing I could have gone and
used a linux server with YSlow which
is an API from Yahoo but i found out
that this is not being maintained, hasn't
been maintained for about 3 to 4 years, so i had to
seek an alternative and in the end i
went for Google PageSpeed, which i'm sure
is an industry standard, it has an API
which we can call as well, so what we've got is
a web service which is calling another
web servers and i'm using google containters
now, I was, looking around for
solutions and found that google are
offering $300 for 60 days for free
and that's quite an exciting offer, and
after reading about the container engine
which allows you to get away from this
infrastructure part where you're
actually having to set up machines
allows you to concentrate more on
programming, i got quite excited and i
ended up landing quite a few new
technologies this week to get the
webservice up
we're just gonna have a quick look at
those steps of the actual service.
what we've got is my localhost here
my machine it should not be working right now
there, i'm gonna fire up a tool called gulp
I did the programming in Node.js
you can see the program here. I have hidden the API key
which you do need to get access to
google and i'm using a Node package
called PSI to make this possible, so
you can see the route here, slash site and if we
go to page now and i refresh this
something should happen.
in fact I could do
my / site and we could give in a
URL like google and see how fast they are
it didn't like that I can't get the URL
what's going on there
um, i don't know, i forgot to put in the
API part
the namespace, so let's add that
100 and we go to my website is going to
be much much slower I would assume
cos Im not using CDN's and all this kind of thing
that they have to their disposal, see it's
taking a little bit longer that obviously
reflects the speed of my website, 42 !?!
I cant believe it, i'm gonna have to
speak with those guys at Squarespace
what are they doing with their servers
well, more about that later on
you seen the source code here, i can actually change
that and let's do a quick check you what
happens when a change is code and I save
it. go back in, i would expect it just
to actually show me. so this is how I
developed the API, it was really quite
comfortable to do that and I find a
tutorial on this very quickly
it was really quite a fast thing to develop
so the next part of this while I kill that
was actually learning docker. that was a
bit more difficult, actually Im quite lucky
I have access to PluralSight that I've
used for a few years
I strongly recommend it as a great resource
and you can do docker images here
and have a look
docker images
you can see I have been publishing different version
of my web api, and,
instead of building something, Im just
actually going to run it
there we go. we should see,
press f5. it's changing again
so now I've got a docker container and actually
the next step you could do there is
using the google command, so there's the
gcloud APIs that you can use
to publish to google and lets have a quick look
google there. so we have the container
engine part of the Google cloud
container registry and you can see actually have a
published version here of my webservice
and once you actually get your app up
there what you're gonna do is you're
gonna fire up a container cluster and
that's really just done in a couple of
clicks you just really just create
cluster and then you're going to have the
option to choose how much memory and so
forth and then within a couple of
minutes your containers are running and
from the command line we do have some
commands there
I think its 'kubectl get services' and
we'll see what I've got published in the
moment. we actually see my page speed
cluster and that's that IP inside the
data center and that's the public IP, so
unfortunately right now my API is not
secured, its totally public to the world
anybody could use it and that's not
really so awesome and google have
provide something called cloud endpoints
and with a couple of code snippets we
can actually secure our web endpoint
which is going to be great i want to do
that next week and we can even try this
so here is our URL let's just check
it's working i might have to down this
site cos i'm not sure if i want the entire
internet actually going on here but we try
it anyway. a bit of copy paste problem
yep it's online that's great it's still
working so know it actually does work
i have managed to publish my container up
onto the cloud and I could also start
checking page speeds so for me that is
actually a job done, it would have been
really awesome if had a button inside
the app you can click and it does it, and,
lets go and have a look at the backlog
for that. so I've come up with a sprint 4
and in that, I've actually said, okay,
the user is able to trigger the website
speed comparison, I think it's this
smaller job now, I just have to call this
web service. to visualize it, is even smaller
job and I want to secure that service
and I've given it a 3 pointer because
I'm still a little bit unsure about
service and then it's not totally
trivia. that's about all I have
to show this week, I wish you all a great
start for the year and i'll be back
again next week. bye for now.

ポーランドの大晦日＆元旦【New Year's Eve and New Year's Day in Poland】Sylwester i Nowy Roknow w Polsce - Duration: 7:46.
Happy New Year!!
Happy new year...How can I say in Polish?
Szczęśliwego nowego roku.
But it's still 31st December now.
New Year's Eve is "Sylwester" in Polish, is 't it?
Polish New Year's Eve is not some holiday.
Many people are working and many shop are opened today.
Even New Year is not like in Japan. Only 1st is a holiday.
Many people start to work from 2nd Jan.
I think sometimes Polish people work hard more than Japanese.
Polish holiday on wintertime is only Christmas season. 25th, 26th...and 24th?
And 1st Jan.
I don't know but maybe few people take a paid vacation?
By the way, I thought I don't have any work today.
But I had to work like usually...
I felt sad "Why I need to clean up someone's house on 31st Dec!!"
But it was everything OK because I got some alcohol after job!
I live in countryside.
So here is nothing some party place.
We will spend at home and before 15 minutes New Year's Day we will go to outside.
And we will be enjoy a sound of a firecrackers.
But I know it will be shabby like 2 years ago.
And will be no people.
Today we are going to make a dish which is a big mushroom and a minced meat.
With drinking alcohol.
Where are you going?
I got some cookies.
I heard so loud firecrackers sound.
From where come this sound?
Someone used a firecrackers in front of my block house.
I was surprised because outside was light.
I got a champagne. I'm glad.
Oh, some Polish guy wrote a comment on my video.
"I have a request"...?
What's this mean?
Please firm a short video about New Year's Eve??
I'm firming it now! I answered your request!
What do I do on New Year's Eve?
I don't do anything, just drinking.
It's still 7 pm now.
Can I be normal until midnight?
I wanna go to outside on midnight.
After one hour we will eat a dinner together.
So until dinner I watch my favorite YouTuber's videos.
I show you my favorite girl.
I'm into her videos recently.
She is Chinese girl.
But she lives in America now and her parents are rich.
They have 3 houses in America.
Amazing...I don't understand.
She likes Lolita fashion and she makes many clothes herself.
She uploads many video about how to make Lolita clothes.
Her name is "Yumi King".
I like this kind of girl.
Because I also worn Lolita fashion before.
I also made some Lolita clothes myself.
I was Lolita 10 year ago?
No, I was wearing when I was university student.
I made few clothes...
She reminds me of my past.
I feel nostalgic.
I don't want to wear Lolita fashion but I like watching.
It's so cute but I can't wear now.
2017 began...
I found myself already in 2017.
Happy new year...
I wanted to spend 0 am on outside yesterday.
I tried to go outside but I fell asleep 30 minutes before midnight.
Nobody waked me up.
So I slept until morning.
I was drank so I didn't remove make up and take a shower.
I hope you will watch and support my videos in this year too.
I will upload some videos this year too.
I remove my make up.
My breakfast on New Year's Day.
This is boiled egg which Polish people love.
And a pickled mushroom.
And a mushroom with minced meat.
Tasty.
I don't have any hangover because I ate this yesterday?
It's already evening now.
Beautiful sunset.
Good bye 2016 dairy.
This is my new diary.
I bought it at a bookshop.
10 PLN.
This cover is just normal paper,
but it looks useful.
It's cute, isn't it?
I put this Arkona sticker.
It's perfect size!
What a cute!
Please watching my videos this year too!

Obama Saved Their Jobs, But They Still Hate Him - Duration: 11:20.
DURING THE GENERAL ELECTION THERE WAS A LOT OF TALK ABOUT
THE ECONOMY AND HOW PEOPLE VOTED AGAINST THE ESTABLISHMENT
CANDIDATES BECAUSE THEY WERE TIRED OF FEELING THE ECONOMIC
PRESSURES BY POLICIES THAT WERE NOT WORKING FOR THEM.
REPORTERS
AT THE ATLANTIC DECIDED TO GO TO SPECIFIC PARTS OF THE COUNTRY
WHERE THE ECONOMY IS ACTUALLY BOOMING AND IT DID A LOT BETTER
UNDER OBAMA'S ADMINISTRATION.
ONE OF THE PLACES I WENT TO WAS
ELKHART IN INDIANA.
THEY NOTICED A HUGE DIFFERENCE
FROM 2009 TO TODAY.
BUSINESS IS BOOMING.
THE ECONOMY IS DOING
WELL IN THIS PART OF INDIANA AND IT HAS A LOT TO DO WITH SOME OF
OBAMA'S POLICIES.
WHETHER IT BE WHAT HE DID WITH THE AUTO
INDUSTRY, THE STIMULUS PACKAGE, IT SEEMED TO HAVE SOME SORT OF
EFFECT.
DO THE VOTERS THERE SUPPORT OBAMA OR ARE AGAINST
HIM?
INTERESTINGLY ENOUGH A LOT OF THEM DESPISE OBAMA.
THE
EXACT OPPOSITE HAPPENED, HE HELPED YOU TREMENDOUSLY AND
HE DID NOT TAKE THE CREDIT.
RIGHT AFTER HE WON IN 2009 HE
WENT TO GIVE A SPEECH IN INDIANA.
IN JUNE HE WENT BACK TO
ELKHART AND IN HIS OWN SUPER SUBTLE WAY BRAGGED ABOUT HOW
GREAT THEY ARE DOING THERE.
HE SAVED THE AUTO INDUSTRY, THE
DIRECTLY SAVED YOUR JOBS IN ELKHART.
THAT MORON, GEORGE W.
BUSH, DESTROYED YOUR ECONOMY.
THAN OBAMA COMES IN AND SAVES
US, IT IS LITERAL AND WE HAVE A 3.9% ON HIM.
THE PROBLEM WITH
OBAMA IS HE DOES SUBTLE, AND THAT DOESN'T WORK IN POLITICS.
YOU HAVE TO BE A BABOON LIKE TRUMP.
THEY GIVE HIM CREDIT FOR CARRIER BECAUSE HE TAKES THE
CREDIT AND
DOES IT AGGRESSIVELY.
IF YOU LOOK INTO THE DETAILS IT IS
HARMFUL BECAUSE NOW CORPORATIONS CAN JUST SAY I'M GOING TO LEAVE
UNLESS THE GOVERNMENT GIVES ME MORE MONEY AND I WILL KEEP
MAYBE HALF THE JOBS HERE.
HALF OF WHAT HE DID IN CARRIER WAS A GOOD THING, HALF
OF IT WAS WHAT ANA SAID.
OBAMA CREATED 3000 JOBS A DAY ON HIS
WATCH.
THE CARRIER TO WAS ONLY 700 JOBS.
BUT OBAMA IS SO
SUBTLE.
IT IS ABOUT YOUR PRINCIPLES AND YOUR PARTY AND
FIGHTING FOR PROGRESSIVE POSITIONS.
YOU SHOULD GO THERE
AND SAY THERE ARE REPUBLICANS WHO ARE GOING TO TAKE YOUR JOBS.
THEN YOU DON'T GET CREDIT.
YOU HAVE TO ACTUALLY INSIST ON WHAT
IS IN YOUR CASE ACTUALLY TRUE.
BUT IN THIS CASE THERE IS NO
QUESTION ABOUT IT, AND YET YOU ARE SO SUBTLE THAT NO ONE
NOTICED YOU WENT TO ELKHART.
MAYBE A COUPLE PEOPLE AT ELKHART
NOW, BUT NO ONE ELSE KNOWS.
I THINK THEY HAVE SOME CREDIBILITY.
I AM CURIOUS TO SEE
WHETHER OR NOT IT WOULD WORK.
I THINK WHAT IS DEFINITELY TRUE
AND HAS SOME INFLUENCE IS THAT PEOPLE ARE VERY POLARIZED RIGHT
NOW. AND PEOPLE LIKE TO PLAY A PART IN POLITICS.
THEY REJECT
INFORMATION THAT GOES AGAINST THEIR PRECONCEIVED NOTIONS.
THEY
WANT INFORMATION THAT REINFORCES WHAT THEY ALREADY BELIEVE.
A
GOVERNMENT PROFESSOR TALKED ABOUT THIS.
TO BE CLEAR IT IS
NOT JUST REPUBLICANS, IT IS DEMOCRATS WHO FALL VICTIM TO
THIS TYPE OF THINKING.
I LOVE THIS STAT.
TO GIVE YOU A SENSE THAT DEMOCRATS ARE ALSO
PREDISPOSED TO THIS.
ACCORDING TO A GALLUP POLL, 35% BEFORE THE
ELECTION THOUGHT THE ECONOMY WAS GETTING WORSE.
BUT RIGHT AFTER
THE ELECTION, AFTER TRUMP ONE, 47% OF DEMOCRATS SAID IT IS
DEFINITELY GETTING WORSE.
A 12 POINT JUMP WHEN NOTHING IN THE
ECONOMY ACTUALLY CHANGED.
BUT BECAUSE TRUMP HAD ONE THEY WERE
LIKE OH I CAN TELL IT IS GETTING WORSE.
THAT IS CRAZY.
NO LET ME
GIVE YOU THE REPUBLICAN NUMBERS.
THINK ABOUT
HOW CRAZY THAT IS.
CONSERVATIVES ARE MORE OPEN TO MANIPULATION,
PROPAGANDA, AND MORE ADVERSE TO FACTS.
THAT IS EMBARRASSING FOR
DEMOCRATS, YOU OUGHT TO BE BETTER THAN THAT.
REPUBLICANS HAVE A 33 POINT DIFFERENCE.
WHAT I AM CURIOUS ABOUT IS IF TRENDS POLICIES PROVED TO GO THE
WAY WE PREDICT AND HE DESTROYS THE ECONOMY, AND PLACES LIKE
ELKHART REALLY SUFFER, WHO WILL THEY BLAME?
DO THEY BLAME OBAMA?
OR DO THEY FINALLY WAKE UP AFTER THEY FEEL IT IN THEIR POCKET
BOOKS AND WAKE UP TO THE REALITY?
I HAVE THE ANSWER.
MAINLY WHAT THEY ARE GOING TO DO IS IF
THE DEMOCRATS HAD OPPOSED TRUMP.
IF THEY HAD LET TRUMP DO
EVERYTHING HE WANTED EVERYTHING WOULD'VE BEEN GREAT.
BUT THOSE
DEMOCRATS BLOCKED 1% OF WHAT HE DID IN THE SENATE.
DEMOCRATS WILL NOT BLOCK ANYTHING AND TRUMP WILL DO
EVERYTHING HE WANTS TO DO.
NOW WHY AM I OPTIMISTIC?
BECAUSE OF FACTS.
I COVERED
EVERY DAY OF TRUMP'S PRESIDENCY FROM THE BEGINNING OF 2002 TO
THE END.
PROGRESS IS RIGHT AROUND THE CORNER.
THEY ALL SAID
IT LIKE ROBOTS.
BY THE END HIS POPULARITY WAS IN THE 20S.
AT
THAT POINT YOU COULDN'T FIND A BUSH VOTER.
HIS POPULARITY WAS
DOWN TO 27%.
THAT IS LOW FOR A PRESIDENT.
THE JURY CAME IN ON
BUSH AND EVEN A LOT OF REPUBLICANS WERE LIKE NO,
GENUINE MORON, TOTALLY SCREWED OVER THE COUNTRY.
IF YOU THOUGHT
THEY CAME TO THE CONCLUSION ON BUSH, WAIT UNTIL YOU SEE THE
CONCLUSION THEY REACH ON TRUMP.
HE IS NOT ONLY JUST AS DUMB AS
BUSH, BUT HE IS ACTUALLY FAR MORE CORRUPT.

Tesla Motors: Radar Mechanics Explained! Autopilot/Autonomous Radar - Duration: 30:09.
hi folks lately we've seen a lot of
impressive improvements from Tesla's
autopilot system one of the major
components of this system is the radar
and because of this radar sensor working
impressive accident avoidance and driver
assistance features we got traffic where
cruise control autopilot
collision-avoidance a pedestrian
avoidance unfortunately zombie avoidance
but that's easily manually overridden by
a sliding on the accelerator whole
different topic anyways I thought we
could dig a little bit deeper into this
radar piece of hardware which is a
amazing tiny piece of hardware that at
that one of my viewers was able to dig
up the Boche manufacturers features in
specs paper so let's take a look at this
critical component i got four pages i
have written note this was a little bit
of a research project for me and that I
learned a lot
so let's dig it dig into it the sensor
is manufactured by Bosh Bosh also offers
a scalable design and can modify the
hardware to suit the needs of the
specific met vehicle manufacturer and
the vehicle requirements because Bosh is
able to tailor the sensor to the auto
manufacturers specs which of course
Tesla most definitely has had some
changes done and of course we also lack
information on what those changes might
may have been
by Tesla we're just going to have to go
based on the publish documentation from
Bosh and one thing although this call
touched on this a little further
one thing I can tell you is testable
claims of distance that the vehicle can
see is considerably further by about 90
meters compared to what box claims are
well touch on that at the end closer to
the end so let's hit up the stock
information here one of the sensors of
multimodal with four independent
received channels and dim digital
beamforming multimodal means that it
varies range and resolution depending on
the target be informing means it is
designed to detect objects within a
certain range digital being forming is
the amplitude phase variation is applied
to signal after analog downconverter /
digital down conversion the received
signals from the antennas are first
passed from the ADC and DC before
summation of the operation being forming
is used for directional signal
transmission and reception it has the
ability to change both the amplitude and
phase with helps that has the ability to
change both amplitude and phase with and
helps with power variation as well as
being steering in the dirt desired
direction
ok let's see what you got
my handwriting was crap so i retyped
everything up
oh my bullet points and notes i got a
lot of them here summed up this all
allows the sensor to be configured into
pit with independent antenna for
different directions improved accuracy
and adjustable field of view depending
on the situation by focusing the radar
at a narrow main lobe with angle of plus
or minus 6 degrees the system can react
two vehicles of long-range and perform
well at higher speeds as well as
maximize interference
excuse me as well minimize interference
from vehicles in adjacent lanes so think
of that as being like okay
autopilot or traffic where cruise
control you're in a clustered situation
you got lots of vehicles around you by
focusing the radar think of it like
focusing flashlight you can zero in on a
specific section or object or in this
case the lane directly in front of you
it helps keep the vehicles on the side
out of that field of view that's
directly in front of you so it doesn't
interfere basically okiya help you keep
proper distance and react quicker to
what's directly in front of the vehicle
the elevation antenna has a plus with a
plus or minus plus minus 42 degree
opening achieves a close-range detection
zone capable of detecting a pedestrian
stepping out onto the road from behind a
parked car as as example as a early
stage of detection due to the high level
of integration of sensor control
functionalities Josh was able to achieve
compact design allowing he's a placement
within a really wide range
a vehicle design so first gen autopilot
it was a sensor on the bottom of the
bumper nothing too special about that
then they realized okay that placement
really kind of sucks gets a lot of slush
snow there so they moved it up and now
it is actually behind the t emblem the
intestinal insignia on the front bumper
of the Refresh design model s cars and
of course behind the tea on the X and
most likely who sees me behind the tea
on the model 3 equipped with a
self-calibration system the sensor
searches for reference points and first
journey and calculates sensor access
deviation from dynamic driving access
axis not access but axis access
there was a system software compensates
for this deviation during learning phase
some features or functions may be
disabled until complete you'll mostly
see this metric house how working out
with autopilot two point oh I with the
autonomous hardware but in autopilot one
point I know when my vehicle was
delivered pretty much deal well no
autopilot in cruise control did work
however a lot of the parking features
and other miscellaneous things i had a
pop-up warning seeing these are not
quite ready yet system is still being
calibrated while blog just as example
and at one point this past summer the
system had to be recalibrated now it's
self-calibration system not automatic
calibration system so when my system had
to be recalibrated actually had to have
service go in and they read set and then
they actually took the car and drove it
back and forth on the freeway in some
city streets a number of times to
recalibrate it
solid-state components or in other words
no mechanical moving parts allows the
unit to have a high tolerance for
vibration that's a plus on wisconsin
specifically Milwaukee roads where we
have summer no excuse me you have winter
then we have a pothole season and then
road construction season
the radar also has radome radome heating
available of which my investigation show
Tesla to have chosen based on my thermal
imagery you can see that video under my
account
radon heating allows the unit to melt
off slush ice and snow that is in direct
contact with the radar sensor so that
build-up unfortunately if it melts out
little cavern can only melt what really
what's physically touching it
so then you got a little cavern of slow
snow slush and ice and you can lose
access to the radar anyways which was a
major one of the major reasons they
raise the center of Tesla raised the
sensor up higher
it's about a foot higher and the
refreshed Model S's than it was on the
original styling the radar uses
frequency band of 76 277 gigahertz due
to triple carrier frequency at 77
gigahertz the sensor only needs one
third of the antenna surface of the
other older existing 24 gigahertz
sensors to cover the same field of view
at the same resolution benefits of this
means significantly smaller allows
measuring speed based on the Doppler
effect which results in three times more
accuracy than the older 24 gigahertz
style units
this allows sensor to intervene at an
earlier stage to reduce speed in
critical situations operation the radar
is designed to detect objects and
measure their speed and position
relative to the movement of the vehicle
which it is fitted to do this one the
radar sends out a wave in the 676 277
gigahertz range via transmission and
tennis two waves are reflected by
objects in front of the video
well relative speed and distance between
the vehicle and other objects is
determined based on the Doppler effect
and the delay frequency shifts between
the sent and received signals are
generated and comparing the amplitude
and faces of the radar signal measured
by the for antenna it is possible to
infer the position of the object
what is the Doppler effect the Doppler
effect is an increase or decrease in
frequency of the radar as the source and
observer move to oral way from each
other
this causes a sudden change in pitch as
example I think fire truck coming
towards you with its siren blasting we
then as it's going ok I guess I really
don't need to do the sound effects so
anyways as the fire truck with its iron
blasting comes towards you the pitch
goes up and then as its driving away the
pitch goes down say they happened with
radar elevation antenna can generate an
additional upward elevation being
allowing the sensor to measure height of
all detective objects to help reliably
classify relevant objects and determine
if a vehicle can drive under or over
them special signal processing
algorithms are used this allows the
system to cope with complex traffic
sexual situations and break more
reliably even in the case of stationary
objects predictive emergency braking is
also available if peb determines the
distance of the preceding vehicle is
becoming critically short at a vehicle
speed above 18 miles per hour hence the
18 mile per hour speed been made
mom for traffic where cruise control and
autopilot it will reap it will prepare
the vehicle for potential emergency
braking if the driver does not react
the system uses audible visual warnings
followed by a short jerk of the brakes
this system initiates partial breaking
and if driver also applies breaks it
will calculate the pressure required to
stop and apply additional force to avoid
collision if peb detects unavoidable
collision and operator does not
intervene it can initiate full braking
that test that
thank you Mike Anthony if collision is
unavoidable even with a eb it will do
its best to mitigate the severity of the
collision the sensor is capable of
supporting traffic workers control up to
93 miles per hour 150 kph and intestines
case also autopilot with a max relative
speed of 50 miles per hour or 80 kph and
works in stop-and-go environments if in
case you're not understanding what
relative speed means ok think of it I'm
going down the freeway at 60 mount 60
miles per hour and a vehicle passes me
going 65 so even though i'm traveling 60
he's traveling 65 are relative speed my
speed in relation to the other vehicle
is a five mile per hour difference so
we're traveling five miles per hour
relative or think of it a two-lane
highway country highway i'm driving 50
the person coming from the other
directions driving 50 as we pass each
other are relative speed is actually 100
miles per hour for each traveling then
away from each other at 100 miles per
hour
I don't think I explain that last one
quite right you get the idea
heading distance indicator can warn the
driver if safe following distance is not
being maintained the units also
incorporate sensor data fusion here's
where a whole bunch of magic happens
they're after me lucky charms wrong
serial sorry sensor data fusion combines
the benefits of different sensors and
measuring principles in the most
effective way possible providing data
that individual sensors working on their
own would be unable to generate this
fusion increases the measurement range
reliability and accuracy video sensors
along with software algorithms are data
fuse with the radar in Tesla autopilot
without the camera car cannot do
autopilot without the radar Crocker to
autopilot needs both and the data fused
together in put it by both to be able to
do autopilot and not kill anybody
this fusion also allows for automatic
emergency braking with pedestrian
protection now
Tesla has been updating software in
really starting to activate incorporate
more and more of these features into
their system actually they're all there
it's just now their programming them to
all work in synchronous asynchronous
synchronicity close enough
one example of this is i recently posted
a video showing my car driving down a
road that had no lines autopilot was in
fact active and doing all the steering
and all the hard work it was using a
combination of the radar the autopilot
camera and the 12 sensors sonar sensors
surrounding the vehicle in order to
maintain a radar Elaine in order to
maintain driving in its Lane even
without those lines on the road you
previously to Tesla activating these
features which is don't do that i was
testing things out
don't do that prior to this that would
have not have made possible so Tesla has
really started incorporating not just
this fusion of data between all the
sensors and program programming that
into the autopilot system but this
fusion is also gonna be incorporating
data from the GPS sensor and the fleet
learning and just mashing it altogether
uses as much of that as it can to to
control the vehicle every extra little
bit of data it can
helps so let's just go over Josh
statement of customer fat benefits one
digital beamforming two independent mode
for height measurements three
cost-effective design for tailored
solutions five self-calibration 6 can be
concealed behind the bumper seven no
moving parts
aight sensor data fusion nine small size
10 high speed and flex relay enter can
in flex really interfaces and 1176 277
gigahertz that covers be sense are the
Tesla radar sensor and as long as we got
it i'm gonna have all this in the
description box below so it's easier for
you guys to reference and access and as
long as we got it using all recycled
paper you know
no throw stuff away print on the back
side then recycle it
the technical features now a Boche has
available both a forward-facing and
rear-facing radar device radar sensor i
am only talking to be talking about the
and have only been talking about the
forward-facing I left out for the
rear-facing because as of right now
Tesla does not use the rear-facing radar
not in current autopilot 1 point 0
matin autopilot 2 point 0 as far as what
we're aware even autopilot on the model
3 and model x do not use the rear radar
only front-facing so frequency range 76
277 gigahertz detection range point 3 6
260 meters so there's that hundred and
sixty meters
that box states and i believe i read
that Tesla systems can see seen up to
250 meters so that is a 90 meter
difference now as i just read with the
with the the fusion data fusion sensor
data fusion how it can change the many
jobs uh combines different sensors and
measuring principles and the most
effective way now this is radar only can
see if 260 meters but it's quite
possible if you combine both the radar
and the camera together the autopilot
camera that you could get that further
distance of sight from the radar or from
the system feel the view horizontal main
antenna plus or minus 6 degrees provides
a hundred and 60 meter distance viewing
distance plus or minus 90 degree gives a
100-meter viewing distance and plus or
minus 10 degrees gives 860 meter fuel of
you are viewing distance elevation
antenna plus or minus 25 degrees gives a
36 meter plus or minus forty-two degrees
gives you 12 meter measuring accuracy
distance point 12 meters for speed
accuracy is point 11 meters per second
and angle accuracy is 0.3 degrees plus
or minus object separation capability
distance point seven two metres speed
points66 m/s and angle seven degrees the
cycle time
maximum or the fastest cycle time is 60
milliseconds so I'm going to touch on
that real quick and interject here that
means was my and then the calculator
let's see
so
so according to Bosh the radar sensor to
actually refresh and take a sample every
60 milliseconds that means it's actually
capable of sixteen point six seven
refreshes per second in firmware 8
according to Tesla firmware 8 has bumped
up the refresh rate from the radar 210
refresh rate 10 Ryo 10 times per second
so that's 100 milliseconds so it looks
like Tesla still has a considerable
amount of room to go that they could
increase the Refresh speed is low as 60
milliseconds i have just to interject
again my thoughts on why they may not
have done this on the one point or cards
with firmware eight might be just the
sheer processing power in these systems
these are all tegra3 systems now the
autopilot two-point old cars have
computer systems the Frankie forget the
exact model by Nvidia but they are
approximately 40 times faster than the
autopilot 1.0 and classic models
computer systems that is fast and that's
all for fully autonomous driving so it's
quite possible Tesla might use more of
that data from the radar in the future
and that will add another 6.7 frames for
per second of data of radar data has
frequency modulation FM CW there's
another 1 i'm going to interject done
max number of detected objects is 32
sorry trigger guide to the galaxy fans
it's not 42 apparently the magic numbers
32 now from where seven with autopilot
and I i went back in when firmware it
was released I touched on this now I
always knew and firm or seven that the
radar would see a maximum about 55 other
vehicles on the road at one time for the
release notes of press release of
firmware eight Tesla said they bumped
that up by five fold so 5 10 15 20 25
wasn't six-fold they bumped up 5464 they
said they bumped it up somehow I think
you'll see the five or six fold and
whatever it was my guesstimation was
that a Model S's radar community tech
approximately thirty objects at a time
that was back that was before I knew
anything about this based on previous
calculations and observations with the
car so it looks like i was only two
objects off once again though customized
radar
how could be processing power we don't
know because Tesla will not tell us or
release that information see weight of
the sensors a hundred 90 grams always
practically nothing
and here is the amazing one it does so
so much with only 4.5 watt power
consumption so it is extremely
energy-efficient now i don't know if
that 4.5 what does or does not also
incorporate the power consumption for
the radio meeting my guess is no
eating generally is going to take a
considerable amount of power and yeah
that's quite a bit there so I'm that is
it
I I know this one is the long one
30-minute video here and it was long
probably boring but if you're someone
who was interested in learning about the
radar systems that Tesla was using hope
I was able to teach us something

I do my best to answer however i'm up to
like a thousand comments a day on my
videos I can having a real hard time
keeping keeping up
all comments and hopefully some of you
out there and fewer land if you have
experienced or have knowledge or any

Happy New Year! - Duration: 1:43.
Happy New Year.
New Year's is traditionally a time to reflect and make resolutions.
In the coming year, we will be asked to reflect on the last four years, and to make a decision
about the future of BC, and what it will hold for our families, our communities, and our
province.
Since announcing my candidacy to run for MLA with the BC Greens, I have enjoyed many opportunities
to meet with our neighbours on the issues that matter the most to them.
I have listened, and I have heard their frustration.
Frustration that issues like education and mental health, issues like affordability,
and issues like climate-change are not being dealt with in Victoria.
I am hearing that people want to vote for change. And not just a change in political
parties, but real change in the way politicians represent the citizens of our great province.
People are telling me that they're tired of polarized politics.
People are telling me that too often politicians are more concerned about who gets the credit,
or who gets the blame.
People are telling me that they want politicians who are willing to work together and be solution-based.
So as we look toward 2017, I'm reminded by a New Year's quote by T.S.
Elliot: "For last year's words belong to last year's
language, and next year's words await another voice."
Let's make the BC Greens that voice.
I wish you and your family much health and happiness in 2017.

3 THINGS I KNOW TO BE TRUE - Duration: 5:09.Well, because today is the first day of the year and
and it's a time for renewal,
time to do something new, I've decided to
do something quite different here on my channel,
so I'm in my closet...
Don't worry, I won't give you a tour of my closet,
but it's an intimate place to
talk about intimate subjects,
so today I'll answer the TAG that I
just created which is about
"3 things I know to be true" because I think
we often end up
sharing unimportant
things on social media,
so today I decided to share with
you three ideas that are important
to me and that I know to be true.
I hope you like it :)
Well, the first thing I know
to be true is that just like we
need to take a shower to clean
our body,
we also accumulate mental
dirt,
so we also need to clean up our
minds once in a while. And there are many
ways to do that, but one thing
that has been helping me a lot and that I think
works rather well
is meditation. I want to
make a more specific video about
meditation soon because I believe
meditation helps in all
aspects of life.
The second thing I know to be
true is that all of us live inside
a bubble.
Some live inside a very small
bubble, very tight, almost suffocating.
Others live inside a bigger
bubble, but all of us live
inside a bubble which is our immediate
reality. And this bubble ends up really
limiting us, limiting our way of
thinking, limiting our way of living,
so I believe that it's very
important to seek out situations and
seek out experiences that make us
get out of this bubble.
And, at least for me, two things that are
very effective and that make me burst this
bubble of mine is traveling and learning new
languages, that's why I talk a lot
about these topics here on my channel. But
there are many other ways as well,
such as reading books out of our area of
interest, out of the subjects we
usually read. And in doing that
we end up really widening...
our reality, widening the possibilities,
widening our horizon, so
this is my second truth.
The third thing I know to be true
is the material goods, things,
pants...flip flops, shoes, bags,
these things don't bring us happiness.
I think that after that first excitment
of having bought something new,
things really don't lead to happiness.
In order to compensate for our lack of
happiness or meaning, we often
consume way more than we should and that
doesn't lead us anywhere,
but I think that nowadays there are so many
messages of consumerism on social media,
especially on Instagram, on
YouTube that we often end up being
swallowed by them and end up going with
the flow without really thinking.
The fashion industry is one of the largest
polluter in the world. It's kind of
crazy the amount of things we
consume
and it's an appeal to our weakness of trying to find happiness
in material goods or wanting
luxury goods to look chic or to
belong to a certain group
and this...I know it doesn't bring happiness,
so this is the third thing I
would like to share with you and I think
it's kind of crazy, right?, that I have to say
this or that I'm saying this, but I
see so many...so many people seeking happiness in
material goods that I think it's important
to say it and to leave this out there.
Well guys, those were my 3 truths. If
you have a blog or if you have a
YouTube channel and you'd like to
participate in this TAG and share with
us "3 things you know to be true,"
answer the TAG and then send me
the link so I can check it out. And if you
don't have a YouTube channel or if you don't have
a blog, leave a comment below
with 3 things you know to be
true. It doesn't have to be very
serious or profound, it can be
anything you firmly believe
is true so we can
start the year learning things that are
interesting and important with each other.
I hope you have enjoyed
this video, I know it's a little
different from what I usually do, but I
thought it was important to do it, this idea came to my
mind, so I hope you have
enjoyed it.
And I hope that in 2017 we all
live more closely aligned
to our truths.
So, xoxo
and I'll see you next week :)

Tesla Motors: Radar Mechanics Explained! Autopilot/Autonomous Radar - Duration: 30:09.hi folks lately we've seen a lot of
impressive improvements from Tesla's
autopilot system one of the major
components of this system is the radar
and because of this radar sensor working
impressive accident avoidance and driver
assistance features we got traffic where
cruise control autopilot
collision-avoidance a pedestrian
avoidance unfortunately zombie avoidance
but that's easily manually overridden by
a sliding on the accelerator whole
different topic anyways I thought we
could dig a little bit deeper into this
radar piece of hardware which is a
amazing tiny piece of hardware that at
that one of my viewers was able to dig
up the Boche manufacturers features in
specs paper so let's take a look at this
critical component i got four pages i
have written note this was a little bit
of a research project for me and that I
learned a lot
so let's dig it dig into it the sensor
is manufactured by Bosh Bosh also offers
a scalable design and can modify the
hardware to suit the needs of the
specific met vehicle manufacturer and
the vehicle requirements because Bosh is
able to tailor the sensor to the auto
manufacturers specs which of course
Tesla most definitely has had some
changes done and of course we also lack
information on what those changes might
may have been
by Tesla we're just going to have to go
based on the publish documentation from
Bosh and one thing although this call
touched on this a little further
one thing I can tell you is testable
claims of distance that the vehicle can
see is considerably further by about 90
meters compared to what box claims are
well touch on that at the end closer to
the end so let's hit up the stock
information here one of the sensors of
multimodal with four independent
received channels and dim digital
beamforming multimodal means that it
varies range and resolution depending on
the target be informing means it is
designed to detect objects within a
certain range digital being forming is
the amplitude phase variation is applied
to signal after analog downconverter /
digital down conversion the received
signals from the antennas are first
passed from the ADC and DC before
summation of the operation being forming
is used for directional signal
transmission and reception it has the
ability to change both the amplitude and
phase with helps that has the ability to
change both amplitude and phase with and
helps with power variation as well as
being steering in the dirt desired
direction
ok let's see what you got
my handwriting was crap so i retyped
everything up
oh my bullet points and notes i got a
lot of them here summed up this all
allows the sensor to be configured into
pit with independent antenna for
different directions improved accuracy
and adjustable field of view depending
on the situation by focusing the radar
at a narrow main lobe with angle of plus
or minus 6 degrees the system can react
two vehicles of long-range and perform
well at higher speeds as well as
maximize interference
excuse me as well minimize interference
from vehicles in adjacent lanes so think
of that as being like okay
autopilot or traffic where cruise
control you're in a clustered situation
you got lots of vehicles around you by
focusing the radar think of it like
focusing flashlight you can zero in on a
specific section or object or in this
case the lane directly in front of you
it helps keep the vehicles on the side
out of that field of view that's
directly in front of you so it doesn't
interfere basically okiya help you keep
proper distance and react quicker to
what's directly in front of the vehicle
the elevation antenna has a plus with a
plus or minus plus minus 42 degree
opening achieves a close-range detection
zone capable of detecting a pedestrian
stepping out onto the road from behind a
parked car as as example as a early
stage of detection due to the high level
of integration of sensor control
functionalities Josh was able to achieve
compact design allowing he's a placement
within a really wide range
a vehicle design so first gen autopilot
it was a sensor on the bottom of the
bumper nothing too special about that
then they realized okay that placement
really kind of sucks gets a lot of slush
snow there so they moved it up and now
it is actually behind the t emblem the
intestinal insignia on the front bumper
of the Refresh design model s cars and
of course behind the tea on the X and
most likely who sees me behind the tea
on the model 3 equipped with a
self-calibration system the sensor
searches for reference points and first
journey and calculates sensor access
deviation from dynamic driving access
axis not access but axis access
there was a system software compensates
for this deviation during learning phase
some features or functions may be
disabled until complete you'll mostly
see this metric house how working out
with autopilot two point oh I with the
autonomous hardware but in autopilot one
point I know when my vehicle was
delivered pretty much deal well no
autopilot in cruise control did work
however a lot of the parking features
and other miscellaneous things i had a
pop-up warning seeing these are not
quite ready yet system is still being
calibrated while blog just as example
and at one point this past summer the
system had to be recalibrated now it's
self-calibration system not automatic
calibration system so when my system had
to be recalibrated actually had to have
service go in and they read set and then
they actually took the car and drove it
back and forth on the freeway in some
city streets a number of times to
recalibrate it
solid-state components or in other words
no mechanical moving parts allows the
unit to have a high tolerance for
vibration that's a plus on wisconsin
specifically Milwaukee roads where we
have summer no excuse me you have winter
then we have a pothole season and then
road construction season
the radar also has radome radome heating
available of which my investigation show
Tesla to have chosen based on my thermal
imagery you can see that video under my
account
radon heating allows the unit to melt
off slush ice and snow that is in direct
contact with the radar sensor so that
build-up unfortunately if it melts out
little cavern can only melt what really
what's physically touching it
so then you got a little cavern of slow
snow slush and ice and you can lose
access to the radar anyways which was a
major one of the major reasons they
raise the center of Tesla raised the
sensor up higher
it's about a foot higher and the
refreshed Model S's than it was on the
original styling the radar uses
frequency band of 76 277 gigahertz due
to triple carrier frequency at 77
gigahertz the sensor only needs one
third of the antenna surface of the
other older existing 24 gigahertz
sensors to cover the same field of view
at the same resolution benefits of this
means significantly smaller allows
measuring speed based on the Doppler
effect which results in three times more
accuracy than the older 24 gigahertz
style units
this allows sensor to intervene at an
earlier stage to reduce speed in
critical situations operation the radar
is designed to detect objects and
measure their speed and position
relative to the movement of the vehicle
which it is fitted to do this one the
radar sends out a wave in the 676 277
gigahertz range via transmission and
tennis two waves are reflected by
objects in front of the video
well relative speed and distance between
the vehicle and other objects is
determined based on the Doppler effect
and the delay frequency shifts between
the sent and received signals are
generated and comparing the amplitude
and faces of the radar signal measured
by the for antenna it is possible to
infer the position of the object
what is the Doppler effect the Doppler
effect is an increase or decrease in
frequency of the radar as the source and
observer move to oral way from each
other
this causes a sudden change in pitch as
example I think fire truck coming
towards you with its siren blasting we
then as it's going ok I guess I really
don't need to do the sound effects so
anyways as the fire truck with its iron
blasting comes towards you the pitch
goes up and then as its driving away the
pitch goes down say they happened with
radar elevation antenna can generate an
additional upward elevation being
allowing the sensor to measure height of
all detective objects to help reliably
classify relevant objects and determine
if a vehicle can drive under or over
them special signal processing
algorithms are used this allows the
system to cope with complex traffic
sexual situations and break more
reliably even in the case of stationary
objects predictive emergency braking is
also available if peb determines the
distance of the preceding vehicle is
becoming critically short at a vehicle
speed above 18 miles per hour hence the
18 mile per hour speed been made
mom for traffic where cruise control and
autopilot it will reap it will prepare
the vehicle for potential emergency
braking if the driver does not react
the system uses audible visual warnings
followed by a short jerk of the brakes
this system initiates partial breaking
and if driver also applies breaks it
will calculate the pressure required to
stop and apply additional force to avoid
collision if peb detects unavoidable
collision and operator does not
intervene it can initiate full braking
that test that
thank you Mike Anthony if collision is
unavoidable even with a eb it will do
its best to mitigate the severity of the
collision the sensor is capable of
supporting traffic workers control up to
93 miles per hour 150 kph and intestines
case also autopilot with a max relative
speed of 50 miles per hour or 80 kph and
works in stop-and-go environments if in
case you're not understanding what
relative speed means ok think of it I'm
going down the freeway at 60 mount 60
miles per hour and a vehicle passes me
going 65 so even though i'm traveling 60
he's traveling 65 are relative speed my
speed in relation to the other vehicle
is a five mile per hour difference so
we're traveling five miles per hour
relative or think of it a two-lane
highway country highway i'm driving 50
the person coming from the other
directions driving 50 as we pass each
other are relative speed is actually 100
miles per hour for each traveling then
away from each other at 100 miles per
hour
I don't think I explain that last one
quite right you get the idea
heading distance indicator can warn the
driver if safe following distance is not
being maintained the units also
incorporate sensor data fusion here's
where a whole bunch of magic happens
they're after me lucky charms wrong
serial sorry sensor data fusion combines
the benefits of different sensors and
measuring principles in the most
effective way possible providing data
that individual sensors working on their
own would be unable to generate this
fusion increases the measurement range
reliability and accuracy video sensors
along with software algorithms are data
fuse with the radar in Tesla autopilot
without the camera car cannot do
autopilot without the radar Crocker to
autopilot needs both and the data fused
together in put it by both to be able to
do autopilot and not kill anybody
this fusion also allows for automatic
emergency braking with pedestrian
protection now
Tesla has been updating software in
really starting to activate incorporate
more and more of these features into
their system actually they're all there
it's just now their programming them to
all work in synchronous asynchronous
synchronicity close enough
one example of this is i recently posted
a video showing my car driving down a
road that had no lines autopilot was in
fact active and doing all the steering
and all the hard work it was using a
combination of the radar the autopilot
camera and the 12 sensors sonar sensors
surrounding the vehicle in order to
maintain a radar Elaine in order to
maintain driving in its Lane even
without those lines on the road you
previously to Tesla activating these
features which is don't do that i was
testing things out
don't do that prior to this that would
have not have made possible so Tesla has
really started incorporating not just
this fusion of data between all the
sensors and program programming that
into the autopilot system but this
fusion is also gonna be incorporating
data from the GPS sensor and the fleet
learning and just mashing it altogether
uses as much of that as it can to to
control the vehicle every extra little
bit of data it can
helps so let's just go over Josh
statement of customer fat benefits one
digital beamforming two independent mode
for height measurements three
cost-effective design for tailored
solutions five self-calibration 6 can be
concealed behind the bumper seven no
moving parts
aight sensor data fusion nine small size
10 high speed and flex relay enter can
in flex really interfaces and 1176 277
gigahertz that covers be sense are the
Tesla radar sensor and as long as we got
it i'm gonna have all this in the
description box below so it's easier for
you guys to reference and access and as
long as we got it using all recycled
paper you know
no throw stuff away print on the back
side then recycle it
the technical features now a Boche has
available both a forward-facing and
rear-facing radar device radar sensor i
am only talking to be talking about the
and have only been talking about the
forward-facing I left out for the
rear-facing because as of right now
Tesla does not use the rear-facing radar
not in current autopilot 1 point 0
matin autopilot 2 point 0 as far as what
we're aware even autopilot on the model
3 and model x do not use the rear radar
only front-facing so frequency range 76
277 gigahertz detection range point 3 6
260 meters so there's that hundred and
sixty meters
that box states and i believe i read
that Tesla systems can see seen up to
250 meters so that is a 90 meter
difference now as i just read with the
with the the fusion data fusion sensor
data fusion how it can change the many
jobs uh combines different sensors and
measuring principles and the most
effective way now this is radar only can
see if 260 meters but it's quite
possible if you combine both the radar
and the camera together the autopilot
camera that you could get that further
distance of sight from the radar or from
the system feel the view horizontal main
antenna plus or minus 6 degrees provides
a hundred and 60 meter distance viewing
distance plus or minus 90 degree gives a
100-meter viewing distance and plus or
minus 10 degrees gives 860 meter fuel of
you are viewing distance elevation
antenna plus or minus 25 degrees gives a
36 meter plus or minus forty-two degrees
gives you 12 meter measuring accuracy
distance point 12 meters for speed
accuracy is point 11 meters per second
and angle accuracy is 0.3 degrees plus
or minus object separation capability
distance point seven two metres speed
points66 m/s and angle seven degrees the
cycle time
maximum or the fastest cycle time is 60
milliseconds so I'm going to touch on
that real quick and interject here that
means was my and then the calculator
let's see
so
so according to Bosh the radar sensor to
actually refresh and take a sample every
60 milliseconds that means it's actually
capable of sixteen point six seven
refreshes per second in firmware 8
according to Tesla firmware 8 has bumped
up the refresh rate from the radar 210
refresh rate 10 Ryo 10 times per second
so that's 100 milliseconds so it looks
like Tesla still has a considerable
amount of room to go that they could
increase the Refresh speed is low as 60
milliseconds i have just to interject
again my thoughts on why they may not
have done this on the one point or cards
with firmware eight might be just the
sheer processing power in these systems
these are all tegra3 systems now the
autopilot two-point old cars have
computer systems the Frankie forget the
exact model by Nvidia but they are
approximately 40 times faster than the
autopilot 1.0 and classic models
computer systems that is fast and that's
all for fully autonomous driving so it's
quite possible Tesla might use more of
that data from the radar in the future
and that will add another 6.7 frames for
per second of data of radar data has
frequency modulation FM CW there's
another 1 i'm going to interject done
max number of detected objects is 32
sorry trigger guide to the galaxy fans
it's not 42 apparently the magic numbers
32 now from where seven with autopilot
and I i went back in when firmware it
was released I touched on this now I
always knew and firm or seven that the
radar would see a maximum about 55 other
vehicles on the road at one time for the
release notes of press release of
firmware eight Tesla said they bumped
that up by five fold so 5 10 15 20 25
wasn't six-fold they bumped up 5464 they
said they bumped it up somehow I think
you'll see the five or six fold and
whatever it was my guesstimation was
that a Model S's radar community tech
approximately thirty objects at a time
that was back that was before I knew
anything about this based on previous
calculations and observations with the
car so it looks like i was only two
objects off once again though customized
radar
how could be processing power we don't
know because Tesla will not tell us or
release that information see weight of
the sensors a hundred 90 grams always
practically nothing
and here is the amazing one it does so
so much with only 4.5 watt power
consumption so it is extremely
energy-efficient now i don't know if
that 4.5 what does or does not also
incorporate the power consumption for
the radio meeting my guess is no
eating generally is going to take a
considerable amount of power and yeah
that's quite a bit there so I'm that is
it
I I know this one is the long one
30-minute video here and it was long
probably boring but if you're someone
who was interested in learning about the
radar systems that Tesla was using hope
I was able to teach us something

comments please put them in the comment
section below
I do my best to answer however i'm up to
like a thousand comments a day on my
videos I can having a real hard time
keeping keeping up
all comments and hopefully some of you
out there and fewer land if you have
experienced or have knowledge or any
kind of smarts dealing with the radars
please help out and respond whenever you
can
that helps me to help you more so that
covers it for this evening
more to come have a happy new year
