Here we agree. I come across as a Tesla fanboy in these comments but I think Tesla's valuation is crazy high, too high, and I still think there's a chance they fail completely like so many other auto companies (a tough business).

My theory is Musk knows the only way he'll be able to compete is attracting the best talent through stock incentives, and to do that he needs to jack up the stock price by pushing engineers way past what they are comfortable with.

An underreported stat is the increase in TSLA outstanding shares, which I think is Elon throwing stock incentives at his employees to make them go faster, as a TPS alternative (for now?)

Two other incredible stories of men who jumped without a parachute from burning/crashing planes from tens of thousands of feet up in the sky and survived.

https://en.wikipedia.org/wiki/Alan_Magee
Alan Magee survived a 22,000-foot (6,700 m) fall from his damaged B-17 Flying Fortress. He was a ball turret machine gunner. Hit glass ceiling of a railway station which supposedly broke the fall.

https://en.wikipedia.org/wiki/Nicholas_Alkemade
Nicholas Alkemade survived, without a parachute, a fall of 18,000 feet (5,500 m). He was serving as a rear gunner in a Royal Air Force Avro Lancaster. His fall was broken by pine trees and a soft snow cover on the ground.

About non-functioning parachutes.
I was reading "Flying Low" by B.K. Bryans who became a US Navy Jet pilot around mid 1960's. When he was going through his training in propeller driven training planes, a fellow student pilot bailed out of a trainer but fell to his death when the parachute didn't open. The trainer plane had no ejection seat so the student pilot had bailed out the old fashioned way, which required pulling a cord of the parachute manually after exiting the plane. His parachute tragically didn't open.

The base commander dropped 10 randomly selected parachutes from the base and NONE opened. A rigger from another airbase nearby was brought in and all the parachutes were all repacked.

> Can anyone confirm if Postgres would die like MySQL did on too big a dataset --- selecting everything without paginating but fetching just one row at a time in the application?

Depends on the client library. A lot of clientside SQL interfaces load all rows into arrays of hashes or such into memory.
Not closer than usual I'd say, it is just the volume of air the plane is flying in that moves over the ground. Like moving an aquarium in a car with fishes calmly swimming inside.
I’m not sure how this is relevant? Production is only as fast as its slowest component; it doesn’t matter if you can bang out a billion body panels per year if you don’t have enough human labor to put the pieces together.
Tangent: agile, waterfall, and the rest are just individual "methods", not "methodologies". Or at least they should be. Unfortunately it seems our living language is allowing this "-ology" to stop meaning "study of" or "branch of knowledge" and start meaning, well, nothing. If agile, waterfall, etc. are "methodologies", then what do you call the actual research and study of the methods themselves? "Methodologyology"? I get it. I like saying big words instead of small words for effect as much as the next person. For some reason, this one in particular really gets me. I don't know why.
That's a bit too strong a statement to make based on a two-year-old still-open PR with an uncertain future. It seems like it might be coming at some point in the future.
Don't forsee Tesla getting to $25K. The Model 3 really costs $50-$60K, and the incentives are going away.
I understand this is purely anecdotal, but every time I'm driven through Compton, I've never had a problem. Almost every time I have to walk down Central, even to grab a drink from the gas station, someone see's me, a smaller white guy, and it always ends with me waving my Kershaw.

I'd say that instead of making self-driving cars as reckless as typical drivers, we should keep the cars driving by the book, and fine the people who collide into them. Will it cause frustration? Yes, but even today, people who try to drive safely and with respect to the law cause frustration too. And I think self-driving tech has enough momentum now that, frustrating or not, they will get accepted anyway.
I doubt it. Google's heuristics are a lot more sophisticated these days due to SEO wars. If you blocked a website for just being spammy in one aspect, you could be blocking a genuinely useful resource or even a website being targeted by malicious parties. I also doubt keyword stuffing in a single HN page would do much to its overall rank.
I compared Tesla Model 3 to Bolt and Leaf.

7-series and 5-series are simply too expensive. If BMW can get it in the 3-series at a Tesla Model 3 price, things will get interesting.

For my purposes, which are not philosophically trained, anti-materialism would be when something so offends your soul (or your will in a more secular sense) that you would rather die than go along with it. I have known this feeling from when I didn't believe, so I know that it is real and possible.

From what I've read of ancient Rome, I suspect I would have preferred a short life struggling against nature than a long one tolerating Romans.

> In particular, one mustn’t stockpile parts on the floor, they must be fed in small quantities at small time intervals.

I'd imagine that is hugely affected by the lead time on the parts in question. If you're in a Japanese industrial town and every part's manufactured within 20km of your factory, it'd be a perfect approach. If you're in Palo Alto, California and some of your parts are manufactured in a Japanese industrial town, then "just enough" stockpiled parts may well be a three month supply.
I doubt anyone could've missed a pin with a big red tag (flag) attached to it. It can't be missed.

American carmakers didn't get it for decades. Even when they thought they did, they performed Lean rituals without real understanding. This was despite Toyota trying vigorously to teach them.
> As I watched Tesla’s messy, hiccuping line, with workers dashing in to fix faulty parts in place, my mind travelled back to the Honda plant I had visited years ago in Marysville, Ohio. Clean, calm, everything moved smoothly. I was so shocked by the contrast that I imprudently voiced my concern. That didn’t go over well with my fellow Tesla owners. I was a killjoy, I was calling their choice into question.

Well, it's exactly the experience you get when you criticize Tesla on HN.
What do you mean by "discrete problems"? By my understanding, weather prediction is basically solving a large system of partial differential equations. Sure the grid methods are a discrete approximation of the true problem, but it is not what I would normally think of as a "discrete problem".

Training a neural network to map "current state of atmosphere" to "state of atmosphere in the future" is definitely possible to do with a neural network, and sounds like a good idea to me.
Visions which completely reimagine things from the ground up tend to presume a much more spatial experience. Lots of VR, lots of AR. I'd tend to agree, except I think that we're going to see things like brain implants a lot sooner than we think. Certainly before our entire stack can be rebuilt from the ground up. So in a way, I almost view it as futile.

That said, I do have some vague notions on some features a ground-up rebuild should have. Namely:

1. Provably secure systems. I'm talking ironclad. Doing for security at all layers of the stack what Rust did for memory safety, and then some. I want to live in a future where physical access becomes a thing again, so we have more cyperpunk intrigue.

2. Simplicity. Composing software should be like gluing LEGOs together. We have some slick stuff now, but it's not there yet.

3. Visual augments to code. Pure visual programming exists, and it kind of sucks. Whether that's just because we're doing it wrong, I'm not sure.

Rust for example would be a hell of a lot easier to learn if I didn't have to maintain a mental model of what everything is doing at all times, and reconciling that against its vast syntax—half of which is inferred by the compiler—which saves work, but makes the learning curve even harder in the process.

Staring at text is just so banal. I'd love to code in something that has a visual representation for every line of code I write, and see that visual representation come alive. Event architectures in particular would benefit from this.

I think if we're reinventing the entire stack from the ground up, having to not tab out and Google things every other minute would also be nice. Somehow in-context documentation hinting has become shittier over time, not better (in my opinion).

-

I've a separate vision for a completely reimagined web which I won't be sharing (doesn't everyone?), but it's worth noting that it builds atop the existing stack quite heavily. It's simply not worth it to try and rebuild the entire stack, even in that case.

I think the only thing that could possibly justify rebuilding software from the ground up is if we first rebuilt hardware from the ground up. A radically different kind of hardware that demanded a radically different kind of software.
I used Arch Linux for a while (~3 years) before making the jump to NixOS.

Many things I got from AUR packages are binary-cached in stable Nixpkgs, not to mention "compilers" (GCC, clang, and various versions of GHC in my case). I don't know when you last tried it out, but binary availability isn't a problem now if you'd like to give NixOS a spin. The only thing I build from source is polybar[0].

> For blind people, these often-derided services are the difference between a full life where we can participate

Correct me if I'm wrong, but from what I understand, a big difference between old "Taxi mafia" and Uber is that the former will service people with disabilities, because they're forced to do so even if it's unprofitable by the same regulations that grant them semi-monopoly, while Uber will happily ignore this segment in its search for market efficiency.
I’ve been to a factory tour. The author’s anecdote is off the mark. What I observed were mostly robots doing the assemble and welding and then the typical assembly line for installing the interiors. It was smooth and had a cadence. Mr Gasee was talking about Just-In-Time (JIT) concepts and lean inventory and when he saw parts on a shelf it contradicted his idea of JIT. JIT doesn’t mean you can’t have safety stock. Tesla is also pursuing vertical integration and prefer to make subassemblies in-house. I have my doubts about Gasee’s agenda.
> A honda civic advertises 40mpg

Buy a hybrid (ford c-max used is about 15K), drive conservatively and you can get that mpg in Bay Area traffic.

There's no way a civic gas gets that mpg on bay area roads, i would guess approx 20mpg tops with an experienced driver behind the wheel.

Also they've disabled autopilot for the time being.

It's an interesting time for Tesla, they feel like the automotive equivalent of AMD - David keeping Goliath honest. How many automotive companies saw Tesla become an actual disruptive threat and then spent tens of billions on self driving and electrification? Tesla isn't going to compete with Honda or Toyota by copying their model (or even their manufacturing process).

Take a minute and look at the bolt and the leaf - they're god-ugly, emotionless, unsexy modes of transportation. Buying a leaf is the result of sitting down with a spreadsheet. Need some anecdotal proof? Think to yourself how many of your coworkers, friends and family you can see driving one. How about a model 3? I see more model S's during my commute than I do leafs, volts and bolts combined.

Another place to look for confirmation is the lithium ion battery line which was built in collaboration with Panasonic. Panasonic is 2/3rd the size of Toyota and are well versed in manufacturing process.

If Tesla wanted to borrow a page from the incumbents they'd be doing so, they have enough brains from those companies already on staff. It's a safe bet that there are very few idiots in upper management at Tesla. Elon isn't the type to ignore a process problem, he's a modeling/simulation junkie and probably figured out something that the others are missing. That's not to say things are perfect, but I don't think they're as dire as the article makes them out to be.

The shareholders have faith, and although Tesla shares are slightly bubbly, they're still doing unbelievably well on most fronts.
Green account too
>and have enough funds to buy things.

Yea but the real answer is opportunity cost.

When it is a gun to your head between physical labor, or winning favor with the guy with the guns, it's an easy decision. In other words, they dont need money to motivate you because your opportunity cost is so miserable.

And even if they didn't pay for themselves, all an IT worker neess is a computer and internet connection.

Look at some of the most talented black hat hackers, Barnaby Jack was just a guy with no education hanging out on welfare with a computer. Sabu was just a drug dealer living in the projects. Jeremy Hammond was a PC repairman that liked to go to political protests. We're kidding ourselves that to be a good engineer (or anything for that matter) you need to somehow be "high class," have branded credentials, and come with an expensive salary.
> Other vendors are forced to keep time, people and money allocated to maintain their 19th century gas engines.

GM had to sell 600,000 high-margin trucks to raise the same amount of funding that Tesla got from investors (VERY ballpark numbers). With those funds, GM also had to invest in over 30 assembly plants around the world and 12 or so product launches, not including engine and transmission programs.
Hmm, good point. I agree with you about patient incremental gain. I wish my boss and other leaders did. Maybe I also work for an Elon Musk, come to think of it. And yet, I'm still not sure my boss and others don't _understand_ lean manufacturing and its related disciplines. They just seem to pick and choose when they want to apply it. I was recently reading about Jeff Bezos and his "Day 1" mantra as well... perhaps the question is whether that sort of thing can apply to cars.
I'd really go with the first solution. However I'm usually using Postgres. And of course it would need to be done in batches at the application side.
"Do you allow remote work?" Anything other than "Yes!" is an org-smell (at least for me, YMMV).
In an era when corporations are constantly accused of short term thinking, the 747 was a bet-the-company deal for Boeing. There was no government financing nor subsidy. It was in service for 10 years before it began to show a profit for Boeing.

And then, boy did it ever show a profit. And not just for the Boeing, but for the airlines who loved its ability to make money.

The 747 was a triumph any way you want to look at it - free market, safety, engineering, money making, pleased customers, etc.

> Conversely, every nutjob with a gun argues against basic supply and demand analysis, saying that restricting the supply of weapons that simplify killing won't reduce the number of killings, when everybody who has gone through Econ 101 knows that shifting the supply curve to the right will result in a new, lower equilibrium number of killings.

Econ 101 also says that if you restrict the supply of guns but not knives or rocks or IEDs, substitution will occur.

So the real question is how much the curve shifts. And we need the real number, not politically convenient fictions like calculating the change in the number of crimes committed using the prohibited weapons without counting crimes committed using substitute weapons. Or claiming credit for a reduction in crime that only tracks the rate that violent crime has been declining world-wide for decades independent of any single policy.

It's not necessarily the case that the result is even in the right direction because of the deterrent effect. It's possible that criminals are deterred by the prospect of being shot by a victim and if you make guns less available then overall violence increases due to the loss of the deterrent.

This is clearly a situation where you need to look at the evidence, except that it's a political issue and each side has their own set of numbers.

There’s a lot of “I don’t want X” in your text but no “this is what I believe in”. This is the core of your issue.

If you don’t have an ideal you work toward then you will always end up hating your job.

You sound like a smart guy, you just need to take some time and work out what your ideal world would be. When you know what that ideal is then work toward it every single day of your life.

EDIT

I’m guessing you’re someone who has looked to others to make decisions for you from the tone of your text.

You need to start putting faith in your own actions and needs, rather than getting advice from others.
> Do folks have practical examples that would make development of alternative computational models worth it?

This is the question to ask people when they say "the von Neumann architecture is a bottleneck".

That being said, I think a strong contender is the dataflow computing model. The advent of the GPU already heavily punishes control flow, and workloads are being increasingly constrained, hence the possibility of a real world success for dataflow machines.

This article lost me after just the first couple of paragraphs. If Leibniz is, as quoted in the text, `recognized for first formally proposing` the binary system - then what relevance does it have that someone had the idea earlier (and thought it was useless)? He is not recognized for having had the idea first, he is recognized for seeing an application of it and formally proposing and specifying it.

Roentgen wasn't the first to observe x-rays either, he was the first to perform extensive studies and publications on them.
I've looked into it a bit. Visualworks smalltalk documentation gave me an idea[1].

In Smalltalk everything is an object, that is including numbers, characters etc. The standar method-lookup searches from the innermost class methods to the outermost class methods.

The method finder could simply iteratively go through all applicable methods that return the class requested and match results.
