"Tesla

VP Autopilot Software
January 30 - June 20, 2017
When I joined Tesla, it was in the midst of a hardware transition from "Hardware 1" Autopilot (based primarily on MobileEye for vision processing) to "Hardware 2", which uses an in-house designed TeslaVision stack. The team was facing many tough challenges given the nature of the transition. My primary contributions over these fast five months were:

We evolved Autopilot for HW2 from its first early release (which had few features and was limited to 45mph on highways) to effectively parity with HW1, and surpassing it in some ways (e.g. silky smooth control).
This required building and shipping numerous features for HW2, including: support for local roads, Parallel Autopark, High Speed Autosteer, Summon, Lane Departure Warning, Automatic Lane Change, Low Speed AEB, Full Speed Autosteer, Pedal Misapplication Mitigation, Auto High Beams, Side Collision Avoidance, Full Speed AEB, Perpendicular Parking, and 'silky smooth' performance.
This was done by shipping a total of 7 major feature releases, as well as numerous minor releases to support factory, service, and other narrow markets.
One of Tesla's huge advantages in the autonomous driving space is that it has tens of thousands of cars already on the road. We built infrastructure to take advantage of this, allowing the collection of image and video data from this fleet, as well as building big data infrastructure in the cloud to process and use it.
I defined and drove the feature roadmap, drove the technical architecture for future features, and managed the implementation for the next exciting features to come.
I advocated for and drove a major rewrite of the deep net architecture in the vision stack, leading to significantly better precision, recall, and inference performance.
I ended up growing the Autopilot Software team by over 50%. I personally interviewed most of the accepted candidates.
I made massive improvements to internal infrastructure and processes that I cannot go into detail about.
I was closely involved with others in the broader Autopilot program, including future hardware support, legal, homologation, regulatory, marketing, etc.
Overall I learned a lot, worked my butt off, met a lot of great people, and had a lot of fun. I'm still a firm believer in Tesla, its mission, and the exceptional Autopilot team: I wish them well."

The first draft ended "In the end, Elon and I agreed that he and I did not work well together and that I should leave, so I did."
>Given that reduced upstream costs typically translate into reduced downstream costs

Can you go into a little more detail about "given" here? I'm not under the impression that it's true.
thanks alot! :D
Also, there is space constraint. Eg, Vancouver: everything which can be built has been built. South, it is blocked by the US border, north by the mountains and native lands, west by the ocean. The only option really is east, though, it directly translate into crazy commute time. Combine this with one of the best weather conditions in Canada (mild winter/summer) and high asian immigration, and that's a recipe for [very] high prices.
These were just a selection of quotes that looked good on the web site, particularly the "GREAT JOB!" quote. That's kind of nice to see.
Yep, this is what happened with my grandmother in West Meade (next to Belle Meade). The land has appreciated drastically, but most new buyers in the area just tear down the existing houses to build something new. It's kind of sad, really.
I agree with that as well. But a glove has it's own problems. It has to fit various hand sizes. It needs to breathe and ventilate to prevent sweat & heat buildup. Combining the requirement for mechanical resistance with breathability is a considerable challenge.
100-year-old physics problem has been solved
They sold a bound at 0.05% of face value? That's an incredibly new kind of low. Why would they ever push for that long term?
Yeah, this is a really simple insight that's not obvious at first. I like the way it's stated in The Wealthy Renter:

> The Golden Rule of Real Estate:... Buildings never go up in value. Ever. Period. ... Only land can go up in value.

I take some minor exception with the absoluteness of the statement (I could imagine a building designed by some architect who later became extremely famous increasing in value), but overall it's obviously true.
In Singapore grab has added taxi's to it's fixed price or you can book a taxi with normal meter fare. At peak periods taxi with meter is about 25-35% cheaper and without peak 5-10% cheaper. The government has also allowed taxi companies to offer fixed fares from their apps the way things are going I don't think uber will be able to compete very long if it actually tries to be profitable.
> Facebook does have all those things in your neighborhood.

No it doesn't. Maybe it has something to do with the country I live in, which is a freedom loving country anyway.

I already started a group when facebook started to be popular. It ended in a bloody ego sniping mess and I deleted the whole thing.
>it's fair to say that cooperation for the goal of increasing diversity is a pretty heavily selected for trait.

It seems like you're making the mistake of thinking that traits we see were necessarily being actively selected for. It's like saying that because we see an increase in complexity in organisms over time, that evolution is selecting for complexity (its not).

It's true that more diverse populations can withstand changes to the environment better. But to then say that the trait of diversity is selected for is a huge stretch. If diversity has no current value then it won't be selected for, and will be selected against in competitive environments. Evolution doesn't have a way to see into the future in that way. Diversity might be selected for in cooperative populations, but only when diverse behavior provides an immediate benefit to the population.
Well you cannot eat, drink or breath gold either...
Gold is impossible to fake, but ETFs based on double-counted collateral and various other fixing fixes have made it a fool's errand to preserve capital with gold.
I've been in Buenos Aires for 3 months in the beginning of the year and I can assure you that if this government stays all startups will shutdown due to impossibility to pay electric and other bills.
Try to make one thing right. That often leads to help you change more things in life.
I live in Grand Rapids, and just sold my house for a price that I never would have bought it for.
Chris accomplished a great deal in a short time at Tesla, but ultimately could not work with Elon Musk. He was a great fit if Elon wasn't a maniac.
Try aptly or debmirror.
This is true. One would have to convince them the restriction would have minimal to no impact on their bottom line. An example of selling open software is Red Hat or SUSE where they continue to make lots of money off enterprise sales despite distros like CentOS.
> It needs to separate out Vancouver and the rest. Vancouver is its own bubble of self-perpetuating nonsense propagated by Chinese money.

Not just Chinese money, see my comment below.

To summarize: 1) best climate for Canada, 2) bounded north, west, and south, 3) land already developed, 4) high immigration
I know there are loads of people that do find enjoyment in Casinos. So I know my perspective isn't the only one by a long shot.

A friend of mine used to be a professional gambler. He stuck to the poker tables... I guess he must've played medium stakes. He did pretty well because you're playing against the other players, so even though the house wins overall, if you're a decent poker player, you can walk away with more than you started every night, and he did and the house still wins. The odds work far more favourably when you're betting against other players rather than the house. He started off without much money in the bank, but he was pretty quickly pulling in enough to cover his rent, bills and never seemed to want for much.

It always seemed to me if the game itself could've held my attention longer than 15 minutes, it would've been a pretty easy way to augment my income. The truth is though, after 15 minutes I'm bored with that.
You might also do this to improve debuggability and unoptimised build performance. The VC++ stdlib is particularly bad, as its authors have gone down the ultra-DRY rabbit hole even for simple stuff - a pain to step through, and it relies entirely on the optimizer doing its thing.

(libstdc++'s vector looks sensible in this respect - a good decision on their part. Haven't looked at any other aspects of it though.)

At one point the contents of vectors were often inconvenient to examine in just about every debugger, because you'd have to type out some infeasibly long expression to get at them, "vec._Mybase._Myval._Myptr[0]", that kind of thing, which you could also fix by writing your own container and simply calling your pointer field something like "p". (Same goes for smart pointers.) Luckily this is much improved in the latest Visual Studio but it may still be an issue elsewhere.
Different ways to debug JavaScript code
I prefer to alienate potential converts than convert JavaScripters! Just joking of course. It is hard to hide hate to a non-language treated as a super cool language. But you are right, I've never thought about it this way. I will change it, thank you!
I have been a longtime advocate of the "I am racist, and you are racist, and we are all racist and that's very bad, like as bad as murder, but it's also OK because that's how the universe is and we can get better at being less murder-y, but let's still keep calling this thing I'm talking about racism" camp.

But this essay makes a compelling argument that racism as used colloquially refers to bad intentions.

I'm willing to concede. I'll stop using racist except in a situation where there is an indication of conscious intent for racial subjugation, thus relegating the word to essentially disappear from modern parlance, but...

What word am I supposed to use instead? I guess I just have to use complete sentences. But that's hard.
As someone who grew up in India, I can attest this about the education system there too. This whole culture of parents always ready to come and fight with teachers over the smallest things just didn't exist. Other than in extraordinary circumstances, you gave the teacher and the system the benefit of doubt.

If you were scolded by the teacher, there was a good chance you would get another scolding back at home once your parents found out about the incident.

Unfortunately (or not?), through what seems to be a western influence, this is slowly degrading.
I've been there in the beginning of the year, planning to stay longterm. Inviable. The cost of living in Buenos Aires skyrocketed these past 2 years (I have a sister still living there since 2010, moving back next month).
You're best off getting traces from a modified runtime to annotate what's going on.
This is categorically false. CSS Grid and Flexbox do have overlap, but Grid complements Flexbox, and the two together get a LOT closer to the "holy grail" of purely semantic markup then either alone.

That, in turn, has real benefits: the less "styling" nonsense is baked into your markup, the more powerful the ability to use CSS media queries and other tools to transform the presentation based on device and other contextual information (e.g. different embedding of the same content)

FWIW, I've shipped "grid in Flexbox" sites. Flexbox was better than the-bad-old-days, but still kinda sucked, simply because of the hacks needed to make Flexbox approach grid layout.
Edmonton & Calgary have both seen moderate price correction (~10%) since 2014.
All of these look like advantages if you're building a monopoly and have a contempt for anything that slows that down.
"Hidden" isn't the same as implicit. State might be hidden in the sense that it is encapsulated. For example, sometimes we want to treat a text field component as just an "editor for a string value," without worrying about the cursor and selection state, or the state of the autocomplete dropdown if there is one, etc. That said, in the fullness of time, you do eventually find yourself wanting access to this state for some purpose or another.

Every time you use an HTML input tag, you are using an abstraction over state, and the first time you need access to the input element's cursor and selection, you realize you've been pretending the element had less state than it had, which is a pretty useful thing to do.

If I can write a form component that needs an "editor for a string" component, specified as a type, and fill that need with a "fancy editor for a string" component that has a more elaborate model that I can abstract away, then I think we're in business, but I can't quite picture how that would work.
> There is a HUGE labour cost in housing

Not for cities like Vancouver. The cost is land. That is where the inflation is. Whenever you price out a house in the far outskirts, it is crazy cheap in comparison.
A New Look for Direct Links
Been hearing this since 2008. Still waiting.
Former Comcast cable technician here. I was an in-house tech, and corporate has ludicrous quality standards and nitpicky, white-glove QC's after an in-house tech leaves a job. However, the company obviously employs a TON of _independent contractors_. Some of these contractors are excellent at their jobs, but a lot of them aren't, and as they're not subject to any real oversight by the corporation, you really don't know what you're going to get. At least, this was the case at the office I worked out of. Based on my experience (and I worked at the company for a while), this is almost definitely 100% true, but it's probably a contractor or an individual corporate tech being lazy, instead of malicious action on the part of Comcast.

The original version apparently ended with the text "In the end, Elon and I agreed that he and I did not work well together and that I should leave, so I did."
With the amount of regulations in truck driving, I wouldn't be surprised if SV clashes with the culture and work ethic truck drivers have to endure. It's good to see this company hiring drivers themselves; those who are open to improving on this tech.
Why would the automated system have blind spots though? If it is viable at $50,000 it is probably viable at $100,000 or $200,000 (automated trucks will roughly double the efficiency of driving because of more hours on the road).

I would think that a physics model would also give a reasonable automated system superior control over where the trailer is at a given moment (and to account for different trailers).
> just make people chat away with people in an area

This was a notable distinguishing feature of Google Buzz.

There's probably a reason other social networks never rushed to copy it.
Good to hear that. Follow us on Twitter. We will have an alpha release in the coming weeks.
The good old days of the previous government, where you could have a warehouse of GPUs mining bitcoins with subsidized electrical bills, are sadly over. Now people have to pay for what they use, like in any reasonable part of the world. Or is there any other country that provides electricity for ridiculous prices where all these startups you say will close will move to?
I have been trying to read a book [jQuery] but its been very difficult for me.

By the time I finish client work it is already mid-night & I'm left with very less motivation, but still reading a page here n there I have managed to cover upto 25% of the 444 pages so far.

I'll read a page now, thanks for the reminder :)
I use LDA algorithm for topic modeling. It has been the standard go-to for a while now within NLP community. There are implementations of it in many languages. The tricky part is cleaning the text, domain specific stopword lists, and in general controlling how text is processed depending on the context to make useful topic assignments when the text corpus represents more than a single field of knowledge. There are also some interesting ways of combining recent advances in RNNs on top of the more old school LDA topic modeling. I think this will be where most substantial advances will be coming from.
It is also very hard to withdraw money from illegal gambling sites. It can be done, but is often a slow drawn out process, to get you as close as possible to the date that you can't cancel. Also don't forget that these are dodgy people who have your home address... And know you've been breaking the law - likely with also some tax issues too on the winnings.
OMG I LOVED THE MIR BOOKS! Yes, they were incredibly simple, weren't littered with images, only essential diagrams. And the English translations were very good... I can only imagine what the Russian language versions were.
It's not a requirement, just a specification of minimum bit rate.

Most movies are still presented at 24fps because higher frame rates apparently look different. The Hobbit was released in 60 fps and the reception by critics was mixed. Personally I don't see it but I'm no expert.
The Black Mirror episode about exactly this got it right, I think.

Forgetfulness is a blessing!
> Are we really extracting from a talent pool of 7 billion?

No. Or rather we are doing it badly. But we don't do any better if we geographically segregate people who otherwise might want to work together. It is an orthogonal (albeit incredibly important) problem. As I said, all of our countries should be investing more in education, in addition to having humane and sensible immigration policies and a reasonable social safety net. But in any case, there are more skilled people in the whole world right now than in the U.S. alone, by construction...
I work at Mozilla, but I'm excited about this because I'm a web developer!

If you've ever tried to use flexbox to align content across multiple rows (like laying out a form with labels), you'd know that it's not a true two-dimensional layout tool. CSS Grid is, and will likely supplant flexbox as a flexbox is merely a one row/column grid.

The inspector is a pretty handy way to see what's going on under the hood, and being able to see the line numbers and named areas is great for visual debugging.
Exactly this happened to me about a month ago. I switched from Provider_A to Provider_B. Provider_A totally sabotaged the connection hardware when it disconnected the service. Provider_B's technician had a very hard time redoing the connection hardware.

It's amazing to me that all these connections are still physicial (as opposed to some software-defined switching between providers). Something akin to software-defined networking.

The post above me is good advice. Despite the temptation and the fact that it is slightly more in your favor, resist the urge to "wrong" bet which is actively betting against the player with the dice. People who play these games can be superstitious and don't appreciate your favoring the odds over their luck by betting against them.
Well, it was pretty good ad for me, so maybe reconsider.
I think those are different questions: why should we teach CS and what ecosystem properties create business value.

But as for the Silicon Valley question... it gets asked and debated a LOT. Especially here on HN, I'd say.
which doesn't mean that the building was worthless, at best, it mean that the new building is expected to be worth more than the old one. With the current easy access to credit, why not ?

If I could upvote you more than once; I would.

I left the site not really knowing what language/s are supported.

After digging through the entire page it looks like maybe C/C++/Java?

There should be a huge button, or something, front, and center. <<SUPPORTED LANGUAGES>>

Looks like a cool idea, but I don't know if I can even utilize this tool.
This looks like trucking's version of off-shoring.

You get paid to train your replacements. If you don't train them, someone else will. It's a no win for them. They don't have pull or unions that commuter train operators have so it's not like they'll get to ride along and supervise the autonomous vehicle, in the long term. Instead, there may be an ops center somewhere in TX where operators intervene remotely when an irregular operating pattern pops up. Those will be fewer operators.

Depending on where you live and your level of income, the most realistic way to think of buying a home may be as simply a more cost effective way of putting a roof over your head than renting would be. It's certainly the case for me.
