It's a different style of development.

SLS burned an absurd amount of money and spent over a decade making sure that the first launch went relatively well, because they can't afford to have visible failures, in part because people are stupid when it comes to testing, and in part because they can only build them fast enough to launch once every other year (unless they're given another ridiculous sum of money and another decade to build more infrastructure).

Starship is testing iteratively, so they spend less money up front to figure out everything before flying, and instead put in a reasonable effort ahead of time and then just fly to figure out what needs improvement. They can afford to do this, because they are designing for mass prduction and because as a private company, they don't have to answer to the ignorant public. Building a new Starship stack is a matter of months, and they're more limited by the rate at which they can test and get through paperwork to launch the things than the rate at which they can build them.

For reference, SLS launched in 2022 and next might launch in 2025, Starship had a close to orbital velocity launch in March (it effectively proved they can get to orbit, it was not actually orbital so as to avoid leaving debris stuck in orbit until they can prove the ability to deorbit) and is expected to launch again in late May/early June.
Instead, the tycoon promised that robotaxis would save the business, even as both of its partially automated driver assistance systems face recalls and investigations here in the US and in China.

A decade of repeated, unfulfilled FSD promises does not inspire confidence in more of the same.

Musk is chasing an illusion instead of simply focusing on making reliable, competitive transportation.

Tesla is no longer a "growth" stock.
It's a bit like video game companies isn't it? Exploiting people who want to work on their passion.
> Fuelling,

They pump tons of fuel per second, obviously automated. Connecting/disconnecting pipes are with that movable platform. Granted, today it's different, and some more operations might be needed, like, say, more careful stage positioning on the launch system after it landed previously, but they don't seem problematic to include, right?

> systems checks,

SpaceX vastly increased number of channels collecting data on rocket performance. They have much better understanding of the rocket state after landing because of that. Some checks could be done on earth, but we surely don't do system checks every time we sit in a car, and this comparison is only somewhat stretched, agree?

> clearing the launch area,

For Super Heavy the landing happens some minutes after launch; don't think there's going to be many people near the pod. The zone below the trajectory will probably be permanently closed, at least for period of intensive pad use, just like it's done for construction projects now.

> launching,

Of course.

> fuel transfer, re-entry, recovery,

All in-flight operations are automated, even today, because there's no crew around. Problems and misses today, but we're just testing.

> diagnostics,

What's the (crucial) difference with system checks? Seems like we're talking about the same goals.

> repairs,

No repairs for the nominally working system. If checks show repairs are needed, the system - rocket stage - goes to the factory for fixes, that's much longer than the time between flights, but we have spares to use while the repairs happen.

> recertification,

What do we need here to do that is costly or takes a long time? How long does recertification take for a commercial airliner between flights?

> snacks for the repair crew,

Well, repairs are supposed to be a relatively exceptional thing, so done in the factory, with full lunches if not dinners.

> lawyers, drinks for the lawyers, et cetera.

All that for customer's money and time, not on a launch pads.

> The goal is automating everything. But even the Falcon family is currently around 3 weeks' sustainable turnaround.

Don't you have a suspicion that Falcons aren't being improved that much now because it doesn't make sense for the current mass flow to orbit and given that Starship is planned to become available soon?
Sorry, but this reads like a kid wrote it.
Just let them go explore.

Make sure they can contact you in case of emergencies, make sure they know your address/phone number, and wave goodbye.

(Obviously if you live near poisonous/venomous things then warn them about that, and set some boundaries.)
Elon derangement syndrome. Many such cases.

> the system is unable to get to the orbit, its not tested.

Yes. Just like every other rocket that is under development.

> Its all high-hopes and conjectures as it is now.

Engineering plans from the company that built the most reliable rocket in human history while pioneering first-stage reusability are "hopes" and "conjectures". They're just spitballing, you guys.

> All of those plans are opinions, that's the problem.

Totally agree. Engineering is more of an feeling than a science.

That’s awesome, I didn’t know SQLite had a bytecode.

Based on my experience writing interpreters, I know that bytecode is faster to interpret.

(Source: I wrote JavaScriptCore’s interpreter and it’s optimizing JITs. I’ve also worked on other language implementations. I’ve seen the AST vs bytecode thing play out more than once.)

The jump target is compiled into the bytecode, so rather than return to the big switch statement, it jumps straight to the next opcode's implementation. The process is called "direct threading". These days a decent switch-based interpreter should fit in cache, so I'm not sure direct threading is much of a win anymore.

Why would assuming P=NP implies an organism could produce all things? The possible equality says very little about the order allowable in P, there.

Consider, we know that Game of Life is equivalent to a Turing machine. It still doesn't immediately follow that any program you write will be found in a Game of Life. Closest we have there, is folks are able to build a VM in it where they can make a program in another language that they can play in it. Realistically, they should be able to skip the VM phase, but I don't see that happening any time soon. (Oddly, this same example goes for traditional computers. Consider something like sorting networks and contrast them to how we usually sort numbers in a computer.)
... so I guess they are not launching any new vehicles?

Honestly it might be correct for them at this point, given they have a decent SKU count now with their main headwinds being macro market demand for EV's and QC production issues.

That said, hard to be a tech growth story without new product.

> The ideal solution is to split the code

I'm sorry, it looks like you did not get the problem: you receive a Task, and you are in a sync environment, and you don't have control over these two constraints. How do you safely wait for the Task to complete?
It proves that engineering is hard and that everything has costs and benefits, and you can't make them go away by just ignoring them. It turns out that "being robust" had a lot of costs we didn't see.

It also shows the harmfulness of binary black and white thinking in engineering. There are choices other than "just let everyone do whatever and hope all the different things picking up the pieces do it in more or less the same way" and "rigidly specify a spec and blow up the universe at the slightest deviation". Both of those easy-to-specify choices have excessive costs. There is no escape from hard design tasks. XHTML may always have been doomed to fail, but that is not to say that HTML had to be allowed to be as loosey-goosey as it is, either.

Had a gradient of failure been introduced rather than a rigid rock wall, things very likely wouldn't have gotten as badly out of hand as they did. If, for instance, a screwed up table was specified to deliberately render in a very aesthetically unappealing manner, but not crash the entire page the way XHTML did, people would have not come to depend so much on HTML being sloppy. The resulting broken page would still be somewhat usable, but there would have been motivation to fix it, rather than the world we actually live in where it all just seemed to work.
That's what it felt like - they were really marketing on the brand. When their stock was rising like crazy it made sense, but now it doesn't.
Tesla boys want “an auto manufacturer run like a tech company” and that’s exactly what this is.
Well this is good news for the future development of other companies chargers!
They did jump to a conspiracy theory: there’s no evidence that Google’s stated reason is hiding an ulterior motive, and as a way to hinder China it’d have very little impact since Chinese companies aren’t dependent on it.

This is not the place to relitigate the lab leak mess but I will note that the conspiracy theorists were continually in a state of wrongness. They contributed nothing but noise because they were starting with the conclusion and confabulating as needed to support it. You can and should expect people to back claims up with logic and evidence.

It's not necessary for the Moon. The reason we're doing it is so once Artemis is done on the Moon, we have a system ready to send astronauts to Mars.

Didn’t they just announce they were working on affordable cars. Seeing as their current line is not affordable by any reasonable standard, surely firing people working on new cars is a shitty message to investors? Also to existing staff!

Bang goes TSLA gains this week.
it was ridiculous that after an absolutely awful earnings call, TSLA stock still jumped because Musk promised to start making cheaper cars. As though he won't screw that up also
Where would they go instead? Massive layoffs seem to be happening widely enough across the board that any real alternatives probably aren't hiring that aggressively.

everyone that was part of lay offs knows they are never as bad as media describe them. They will be alright.
For MechE, AE, and parts of EE you are not wrong - they definitely paid well above market rate because of the stock, but plenty of companies like Toyota, Ford, GM, etc began recognizing this and have begun raising salaries around the 2020-23 period while Tesla's remained stagnant, and we'll probably see the result in the next 5-7 years as these are lagging indicators.
That's really more of a "won't", than a "can't".

Sure, it would be impure, and not top-to-bottom reproducible, and you don't personally have to do it. But it's a choice to avoid a compromise, not an impossibility precluded by the laws of math or anything.

Regardless, I no longer really sympathize with Free software's concept of a "freedom" that results in either (1) obscure purity, or (2) benefits large corporations at the expense of the rest of us.

RMS was economically naive, despite his counter-cultural leanings; I can't help but wonder what Free software would have looked like if he'd imagined the likes of MS/Amazon getting rich off it while creators get a pittance. We can't all have free-floating MIT jobs.

The WHOLE POINT of this app and this post is the abortion ban in some states in the US, otherwise this topic or app would never come up. We can pretend we are all idiots but lets be intellectually honest about what this post is about.

Now, is it a valid fear that white conservative males are trying to obtain period tracking app data so they can persecute young women having abortions? I personally don't think so, which makes this app and this whole discussion moot.
Company has had a long head start, and could have focused on core assets of a car instead of dreams that never happened and seem likely to never happen.

Not withstanding how folks might reasonably hate the CEO, or want different features than offered by the two main selling affordable cars, Consumer Reports is pretty easy to check and there are far, far, more reliable electric cars at this point.

The reality distortion field of "every negative thing out there is just a personal attack out to destroy Musk" only holds out for so long.
I'm pretty averse to working in any of Musk's companies, not just Tesla.

It's not his (pseudo?) conservative views, I'm actually somewhat politically conservative. I just have a ton of antipathy toward him as a person. I'm not proud of this, but he's a person I actively want to fail.

I'm curious how common my viewpoint is.
On the supercharger side, there is a lot of battery tech work and providers now in the US, because Sequoia went gung-ho on GreenTech funding and most automotive companies are now working on charging tech too in order to avail IRA subsidies, so there is a growing Battery Tech and charging tech scene in the US.
Thanks. I'd assume the boil-off should be insignificant, in a sense, or - alternatively - some active cooling systems can be used, they don't need to be big or complex.

But why would you set that as a pre-requisite?

The Gateway is also, as I understand it, a staging ground for testing habitation for a vehicle to Mars.

Oh come on. Anyone talented doesn't have to beg for anything, and certainly not a role at a falling company.
> Hyperloop is just a wild bullshit idea

hindsight 2020, there have been bilion of $ thrown at it. Musk was promoting it as easy thing to do. And yet its "wild bullshit idea" how come reusable rockets is not a "wild bullshit idea"?

I dont understand how people can eat anything up Musk wildly claims and forget all BS the moment it turns out it was BS.

According to his claims, he will have people on the way to mars last year, for sure.

How come people who hired bunch of grannies to knit a nav computer memory got to moon without loosing a single rocket. And now loosing 3 rockets and still not orbiting is an amazing achievement?
This so far is the biggest sting to current Tesla owners. A lot of the stupid stuff it was kind of possible to ignore because it didn't affect the ownership directly, but this is insane.

Superchargers have been the greatest competitive advantage of Tesla for as long as the company existed. They've been so great at keeping them reliably operating , drastically easing range anxiety for Tesla owners. With this layoff I expect the Supercharger network to become just like the rest of them: broken over 50% of the time.

One of the exciting things about the broad switch to NACS in the US was that other fast charger networks were going to have to compete with Tesla's network, which might have brought the level of reliability and ease of use up dramatically. Instead, we're going to have zero reliable fast charging networks.

I think this broadly dooms the EV movement in the US. I need to sell my Tesla and I guess get a PEHV or something.
I'm CTO over at https://skatespot.com -- we're about 3.5 years into development. Our app is finally live (we pivoted from pwa to native mobile apps using expo/react because maps weren't very accurate in browsers). It's been slow but now we are focusing on growth.
Yes, exactly, that’s the point. Apple did it to themselves. They didn’t “silo off the two product groups”.
Or maybe you don't cripple the future of the company to pay your self-destructive CEO $56 billion.
There's a George Hotz lecture somewhere where he evicerates the Robotaxi business model.

Essentially he makes the point that, if you have to own a fleet and maintain it, even if you stop paying driver's wages, you're not making profit compared to market rates for Uber drivers. Sad implication is that uber drivers themselves are underwater after taking into account depreciation and maintenance.

A fleet where Tesla operates a network without needing to own or maintain the capital equipment is a lot more profitable, and they're one of the few companies positioned to pull it off (certainly not Waymo). Essentially, Tesla could make money on the vehicle sale, make money on the maintenance, and make a platform fee on the taxi network. Wonderful economics on paper.

Win-win too: the car-owners supply the capital and in return receive the freedom of their own car plus an offset to their depreciation via the rental cash flow. That would mean that teslas would have incredible resale value compared to 'dumb' cars that don't produce cashflow.

That said, trust in the network is key, and Tesla + Musk aren't exactly winning public trust recently. If this is going to work, each incremental rider needs to be able to trust that

- if they try to book a Tesla robotaxi they will be able to find one available, nearby and in the time they want it

- the car will work (well maintained, enough charge for their trip duration)

- the self-driving will be safe

While all those things are straightforward, to be honest, it's hard for me to imagine how they can provide a better value proposition than human Uber/Lyft in that regard, where in major cities a car is always 10 min away or less, and the driver has both a financial and survival interest in ensuring it's well maintained and safe (the driver's life also depends on it).

Maybe the niche will be suburban or exurban places where human ride shares don't have enough demand to efficiently match with supply, and where people are okay waiting / planning in advance if they're sure a car will come. Could be some overlap with starlink market fit.

I think it's oddly telling or suspicious at the very-least that this dev isn't giving you a straight answer to your question.
Gah! That headline sucks. It makes is sound like he laid off EVERYONE that works on those parts of the company. No, he sacked the head of those efforts, right?

Musk is still nutty and erratic, but lets get the headline correct people.
They guy could just double-down on scaling out Supercharger infrastructure and make an absolute killing. Instead, he's pinning the company's future on a technology that won't likely come to fruition any time soon.
Is your app open source? Could really use something like this and only need something simple. To me the most important feature is open source (for privacy and longevity).

> If you don't have clarity of thought, no intelligence in the world can help you.

This is clearly not true, just look at the tech industry. We have product managers, who in the most literal sense, do not know what they mean when they ask for something. They are paired up with people much smarter then them, who try to figure out what they mean, and then deliver that.

While this is far from ideal, it's proof that if you don't have clarity of thought, external (human level) intelligence can help you.
More extra terrestrial life soft reveal! I predict we will find that Kepler 2-18 b does not harbor life after a closer examination. Further, several other exoplanets will pop up with molecules only produced biologically on earth before it's revealed that Io or Europa have life in their subsurface oceans. The exoplanet thing is a head fake.

What is he even thinking when getting rid of nearly the entire Supercharger team? Does he expect the few people remaining with no head of the department to be able to effectively coordinate expansion? Especially now that it's becoming the standard for a lot of US electric vehicles?

Along with a majority of the public policy team and the Director of Vehicle Programs, what does this leave us with?

Do we expect Musk to be competent in public policy nationwide? The man doesn't even know how to fire people at Xitter without getting himself into a bevy of lawsuits for violating multiple labor laws.

Ah yes, the HN bubble. The role at these companies are hell to get into, its not a 3 month bootcamp role. Web Dev being hilariously easy to get into was a function of free money.
For most of the 2000s and 2010s, salaries were fairly low in the automotive and aerospace industry compared to software or pure hardware, so Tesla and SpaceX absolutely paid miles above competitors, but that's changing in the 2020s now that there's more money in both spaces.
The only reason air travel is affordable to middle class people is due to the economies of scale.

This is the same goal with SpaceX. To drive the price of ton to orbit down a lot. That is the only way a city on Mars happens.
