I actually think this is a very good analysis. A lot of Tesla vehicles feel like they value form over function.

What really was interesting for me, was the fact that electric trucks from more established players exist already, but haven't really taken off.

Maybe the Musk x-factor will allow Tesla to sell their truck where others have failed.
So... Bram won't accept their input, so they go make their own product with their input, and you call it arrogance. Got it.

You have every right to disagree with people's patchset, just as they have every right to disagree with your direction and decide to do it their own way.
Elon is the rich boy here.
I rolled out a temporary fix which should resolve the image loading issues.
This may be a well informed take (or not), but it's hard to think he doesn't have an axe to grind when the first sentence is an information-free put down ending in a clown emoji. Would love to see a more neutral analysis.
> but the WDC segmentation model was cleaner, etc...

Eh, I don't think this is generally true. Intel's decision to have the segments overlap so much was definitely very short-sighted, but the 8086 has a big advantage in having multiple segment registers with the ability to override which is used via an instruction prefix. This makes copying data between two pages straightforward on the 8086 whereas you need to constantly reload the databank register on the 65C816.

I think as a pure 16-bit design the 8086 is actually pretty good. It's not at all a forward-looking design though so it wasn't well suited to being the basis of the default PC architecture for decades to come.
The history of adtech tells me I can pentest "fine" by squashing so many ads into the disclosure that your device starts to get hot.
The cab forward design that OP prefers is so much more sensible and practical than the "standard" cab design that's so common in the US.

The Tesla Semi is more aerodynamic than its peers though. I wonder how you can improve the aerodynamics without having a narrow front or sloped windshield.
I genuinely had the same thoughts. Just the fact that it was so clearly different showed that Tesla hadn't even talked to actual truckers about it. It's significantly more cramped than a roomy American style cab, and has very little room for the things a trucker might bring with them.

Truckers also occasionally bring family with them on some trips, and this cab makes that kind of thing impossible.
In a sense, Uber. Billions of dollars invested with the promise of winning the race to self-driving. It wasn't the only massive mistake they made, but after they killed that homeless lady in Arizona, they killed their self-driving units as well.
Probably not because it would be hard for most businesses to wait 180 days to get paid.

Well we also have these magic machines that drive themselves around. And pretty soon we’ll be able to use our magic surfaces to order them to take us places.
> A lot of Tesla vehicles feel like they value form over function.

As far as I can tell, that would be all of them. And if rumors are true, Tesla might be about to escalate that to the next level with their bread-and-butter cars. Brave, or stupid, ask in a year.
This completely missed my most contributed to (public) repository. Hmm...

EDIT oh! The data streams in. Had to wait a bit more and refresh to not get a partial result.
I agree with the complaints it’s not built for/around the driver. It’s built for range. Having a vertical windscreen just isn’t going to be efficient. The window deicing problem is worth solving to get the range of a streamlined front. The next iteration of this vehicle will likely solve many of these complaints (of which some seem poorly designed for no obvious reason) but I doubt it will ever have a vertical windscreen.
Does “massively parallel simulation” help advance Reinforcement Learning?
NVIDIA's Isaac Gym project revealed GPU's capability of performing massively parallel simulation for gym-style environments. Detailed information can be found in the following paper:

[1] Makoviychuk, Viktor, et al. "Isaac Gym: High-Performance GPU Based Physics Simulation For Robot Learning." Thirty-fifth Conference on Neural Information Processing Systems Datasets and Benchmarks Track (Round 2). 2021.

At its release, people commented on Twitter that "it is the MNIST moment for reinforcement learning." And over the past year, I saw several follow-up works and tested NVIDIA's implementations.

For example, a demo by this blog

https://towardsdatascience.com/a-new-era-of-massively-parall...

The question is, does that technique help advance Reinforcement Learning, as expected?
Why not just stick to the older, more convenient design?
Vim already does a lot of this between syntax highlighting and the fact that markdown is designed to be readable as text. I think it's an interesting space though.

One thing that would be cool is image support for terminals that support them.

I'm also curious (tangentially) if there are any terminals that support different fonts and sizes (at the same time)?
This actually gets into "regulated" vs "buyer beware" banking markets. And crypto is still a "buyer beware" market where reputation can be bought with super bowl ads. And then getting "glowing" reviews from the crypto press on their sudden "success".

True custodial banks could in fact be fraudulent for allow e know. But they don't buy super bowl ads to buy reputation -- they've earned it over the course of decades.

Real banking should be boring.
GitHub's command line tool does a pretty good job of this, it does emoji too.
“sequential tokens are implicitly list items in a list context” (lisp family, REBOL, and some others) works if its not clashing with something else, like “sequential tokens are implicitly function/method calls” (Ruby, Haskell)

Of course, if sequences are callables that reproduce the original sequence with the argument appended, then these kind of merge, but with empty list as a prefix instead of list bracketing.
Plenty of “rich” blue collar people in the Midwest have equipment that is much more expensive/luxurious than would be required for the job.

For example, $100k pickup trucks are not necessary for farmers but still very common.
It is not interesting just to see that the design is bad, but that it is getting worse over time. Model S was relatively normal car. Model X added crazy doors. Model 3 has tablet in the middle and no physical controls and bunch of other stupid decisions (but normal doors). The Semi has all these issues. And the Cybertruck is just entirely plain idiotic as a whole.

It is as if the Tesla designers (or Musk micromanaging them) are getting more and more detached from reality.
>> Audio on linux is a complete joke

Yes, for example, the zoom app is now one of the most widely relied on apps for connecting people over networks. To get its audio output to fairly represent the input (e.g. for musical content), the input client is supposed to use the 'original audio' setting. That setting is not yet available on the linux version of zoom. On the output end, the audio is a mess, sounding as if somewhere along the way a handshake has turned into a fistfight.

Audio is complicated. Another example: an ordinary amateur, part-time, casual guitarist might nowadays play with thousands of dollars of pedals and processors plugged into his signal path. He gets this to work by plugging and unplugging those devices and their cables in various configurations until everything sounds best. Try providing that level of flexibility in software with reasonable default settings for all of the myriad of applications and environments in which one might try to apply computer audio.

Loves public transport and hates driving? Not awfully likely in the US. Our public transport is fairly abysmal outside a few large cities.
Obviously nothing is "just that simple", if that's your only point so be it, but that isn't telling us much since this is true of literally everything.

Seems weird. How do you service it? How do conductors work? How do you keep random junk from blowing on top of it? How do you clean it? The photo in the story just looks like a giant square of PV material. Is that really what this is?
This sounds very much like a "designed in California" problem. Who would have thought about mud, frosted mirrors, border crossings…
Yeah but it being more luxurious than required doesn't make it ill-suited for the job.
There's actually a similar but much more widespread talking point about gas, claiming the price of that is set on the international market and therefore the UK producing more gas locally would not help reduce prices. That should come with the exact same caveats (only to the extent that it can be imported and exported, American prices are much cheaper for Europe's because of this, and that's likely a big reason why electricity prices are much lower there) but the mainstream media unfortunately ignores them.
My expectation is that Teslas real play with the Semi is a long term plan for self driving trucks.

It seems to me that "backhaul" routs are the most likely to benefit from self driving, either with a person on board or not. Use a self driving truck, where you aren't paying a driver by the hour. It doesn't need to overtake, can drive at the most economical speed. It can stick to very well controlled and mapped routes. Restrict them to certain lanes on the road. Place depots at the exit/entry points to the backhaul where the cab is swapped out for one with a driver.

They may claim this is "designed around the driver", but the reality is it's designed around (eventually) making the driver redundant.

Why design a cab to be optimised to the driver when you plan to remove them. No, you design around efficiency, that's what they have done here.

That's not to say I believe that Tesla will achieve that, or that this can is well designed. I think it will be companies with a long history in the industry, understanding of their local markets, that will do this.
It is correct that mounting costs and labor can be a large portion of the total BOM.

Even for a large off grid whole home PV system that can operate through December/January at high latitudes.

Let's say for an example you wanted to DIY a PV system that would be much too large to fit on the roof of a normal sized house.

Go calculate the cost of buying 30000 kW of good quality 72-cell PV panels rated at 380W STC each. It'll be something like 80 pieces at about $130 per piece.

Usually would ship as 20 panels per pallet, so call it four fully loaded pallets of 72-cell panels.

At 34 cents/W STC rating, PV panel cost from distributor something like $10,400 to $12000 USD.

The foundation work and poles/racking to do a basic ground mount will be a huge cost on top of that. Labor is a big part of it. If you're hiring people to build it the labor and ground mount gear and things like basic foundation work/screw piles/steel tubes set into concrete could easily cost you another 10 grand from a local contractor.

Something generally along these lines or an industry competitor of it:

(Not discussing inverters/charge controllers/batteries/disconnect boxes and wiring here).
My guess is that they needed to get the drag coefficient down, and did so by first raking the windshield back, then pinching the cab horizontally to get some more gains. That narrowing of the cab then led to the center-seat arrangement?

Bonus being that you don't need to configure a LHD and RHD version of this truck for different markets.
are you using `less -r` to pass through raw ansi code?

it also looks like it has a `-p` option for a pager

> CLI output can be displayed in your preferred pager with the -p flag. This defaults to the ANSI-aware less -r if $PAGER is not explicitly set.
Many people can drive for Uber for fun, doesnt mean more people do it because they're destitute and without other options.
I’d be far more interested in hearing thoughts from someone who has actually driven the Semi.
I hope the fields never flood and the solar farm is under water
The cab-forward design is driven by Europe having a max length for trucks that includes the tractor, whereas in the US the max length doesn't include the tractor.

For this reason I don't expect to see the Tesla Semi in Europe soon.
Probably not the most expensive but certainly one of the most prominently featured failure in the early days of the internet.

Yeah, its not as if a cab redesign would be difficult if that ends up being an obstacle. TBH, though, I'm guessing it works better in practice than they let on. They've had a few years of testing, for better or worse.

The Model 3/Y have many physical controls and is great to drive! The doors on the X are pretty silly though.
The first one will probably be full of obvious AI artifacts. In Stable Diffusion images the hands give it away.

Stage one of that is probably "Convoy Mode" as they call it.

NOTE: not talking about feasibility one way or the other, just mentioning that they have claimed similar goals in the past.
The older design isn't as aerodynamic. And that's very important for a battery-powered truck.
You will hopefully be relieved to learn that TSOs specialise in covert evidence-gathering technologies for serious crime investigations, and are not making machines to blow your legs off or shoot your face in.

They're part of the teams taking down human trafficking rings, violent gangs involved in the drugs trade, terrorist cells, and suchlike. The kind of high impact police work that helps make vulnerable people's lives safer.
> is it right that certain groups wield such power?

What groups? Randos on the internet? What power? Boycotting?

> The outrage culture is insane.

Was there outrage? Seems like apple just prematurely cut him loose before anyone actually cared.

It sounds like you think there's some nefarious shadow league of extraordinary gentlemen who can bend the largest corporations to their will. They can't. Apple did what it thought would yield them the most profits in the long term, that's it. Apple could have instead just ignored this and it likely would have blown over in a day. That's not what they did.
Tesla knows all this.

This truck is for a very specific niche: owned fleets near two warehouses or within a 500 mile round trip from a major port. Basically: all the warehouses in the Inland Empire near LAX and Long Beach and the warehouses in the Newark area that service the NYC metro area. It has the potential to dramatically reduce costs for some routes/corridors.

It will be a big hit in these areas. It will have a large impact on a very specific niche. There's nothing wrong with that. These aren't going to be used by independent truckers. It's not for them. It's for drivers making the same 80-100 mile or so trip from port to warehouse every day.
I make around 200-300 USD per month through https://gifmemes.io. Basically zero maintenance, but I'll add user generated templates one of these days. Will be nice to "automated" content generation in addition to "automated" income generation.
That may be, but that's exactly the irritating thing about Tesla. They make great drivetrains, but then anchor them to all these "innovations" that most people don't want. These sound like the truck equivalents of falcon wing doors, yoke steering wheels and touchscreen HVAC controls.
The cost of any private school in my area is in the range you described. Some are good, some are not. My daughter has done extremely well in a Montessori school so far. It is unfortunate your friend’s son did not. Montessori might not have been for him or the school might have just genuinely sucked. My nephew didn’t do well in Montessori and my sister had to pull him out. He’s doing better in a public school.

My mother and mother-in-law were professional teachers (elementary/middle school) with graduate educations (masters-level for my mom and specialist with most work complete for her Ph.D for my MIL) and both approved of the school and my daughter’s progress. So, I guess, I’m personally not very worried about the horror story you described.
> less than 2.5 acres per megawatt

This is actually quite amazing. I wonder what the lifetime is for the panels.
Here's a book published in Britain in 1990, titled "Family and party games", which mentions calls it "BuzzFizz", but isn't quite the same a "FizzBuzz" ("57" is read a "buzz fizz" because the "buzz" replaces the 5 and "fizz" replaces the "7" and 57 is neither a multiple of 5 nor 7.)

https://archive.org/details/familypartygames0000diag/page/12...

Here's another British book from 1990 (reprinted in 1992), where FizzBuzz are for multiples of 3 and 5:

https://archive.org/details/algebra0000maso/page/10/mode/2up...

While from 1990 here's a US book which says "Fizz-Buzz-Fizz" and "Buzz-Fizz-Buzz" are well known, before describing "Reverse Buzz". It uses numbers with 7 in the base-10 representation, and numbers which are multiples of 7:

https://archive.org/details/greatgamestoplay0000harr/page/78...

And another 1990s book from the US does the multiples-of-5-and-7:

Conclusion: the game has been in the US and the UK for a long time.
> Model 3 has tablet in the middle and no physical controls and bunch of other stupid decisions (but normal doors).

Which is a dealbreaker for me as well, but people seem to accept and/or like it. The number of orders speak for themselves and, while I hear a lot of complaints from owners, the tablet is usually not one of them.
Cool - seems to have a problem with my face/beard/something though - none of the avatars ever fully close their mouths, which makes for some very unsettling and unrealistic looking videos...

The difference isn't the means, the difference is the scale. Microsoft acquiring exclusivity for all of a big publisher's titles is different than a single or even a few titles.

Would what be the same? Would it still be bad and I believe the FTC should block it? Yes. But there's also a lot more variables than just once sentence hypothetical.
Rust will be much lighter than any JVM app, but a fairly complex JVM app can be compiled to a self-contained JVM distribution on around 25MB these days... you use jlink to compile the app and parts of the JVM that you actually use.

Not to mention you can use GraalVM native-image to compile to a binary directly, in which case it'll be even smaller.
This aspect is pretty key. My observation has been that build systems will be as slow as people will tolerate.

Effort and money will only be expended to make things faster when the build times are perceived as intolerable.
We shouldn't switch to battery-powered vehicles until they can replace our current ICE vehicles.
You seem to be confusing the claim hackery is integral to and inseperable from Gladwell's effectiveness rather than orthogonal to it for a claim that hackery is sufficient for his effectiveness.

Those are... not the same.
I am not a trucker, so I can't comment on the veracity of TFA's claims. But this rant reminds me of many similar things I've read about products that were designed by people only had superficial experience with the industry they are trying to disrupt.

A lot of the things that matter aren't necessarily obvious to the designer or engineer who knows little about the nuts and bolts of every field. The usual remedy is to either follow a design process that incorporates user viewpoints, or to hire people with direct experience in the field.

Take the "wiping the mirrors" complaint. One design makes it easy to lean out the window and wipe the mirror by hand. Another design might make the mirrors retractible.

If I read a complain that retracting the mirrors was unnecessary complexity, I would think "Hmm, maybe, but then again it's a tradeoff because the narrow cab is more aero and increases range." I'd have a feeling that the designers knew this was an important use case, but this person complaining doesn't like their solution.

But it worries me that a number of use cases that seem quite obviously common even to a layperson... Are neglected outright. I don't get the impression that Tesla knew about all this and decided not to do anything about them, I get the impression that this is a company who thinks "design" is all about styling, and not about usability.

Somebody resurrect Steve Jobs.
I can't speak from the perspective of a truck driver, but I drove CAT vehicles in the military in-country. We lived in them as well. The reason the boots part is important is because if you're living in a vehicle the dirty parts house a lot of nasty stuff that will get you sick. To offset that, you pull everything out of the truck and clean it. If you have to keep doing this then it adds stressful and exhausting repetitious work to your work life. If you ignore it you get sick. It's easier to pick a truck that matches your needs, and frankly, it's usually the small things that matter in big purchases.
How do you do that for IAM?
