One relevant difference is that a better-quality human answer is correlated with certain "tells": correct formatting and grammar, longer answers, higher reputation. An incorrect LLM answer looks (from the outside) exactly the same as a correct answer.
Longer isn’t always better for trains. Longer trains need bigger platforms and stations are often the most expensive parts of the network. Big trains also weigh more, so they accelerate slower and have longer trip times.

Weight savings can also translate into cheaper bridges and viaducts, though that’s only true for dedicated track. If you’re sharing with freight they are always going to be far heavier.

Much better is upgrading signalling, automating the train, and running far more service because frequency is king for public transit. Many short trains at high headways vs less frequent long trains has the same total capacity but the short, frequent trains provide far more value. When people don’t have to think about the schedule and can just show up and ride public transit is great.

There are also limits to the value of standardizing rolling stock. You don’t want every train set to be bespoke, but there is also danger in every train being exactly the same. If there is a parts shortage or identified design flaw your whole fleet can be grounded all at once. If you have some diversity you can limp along if one design has to be sidelined.
tl;dr: Hardware is cheap. Engineers are expensive.

> Instead of fearing the overhead in PHP for function calls,

Already in 2015 in almost all applications this is a premature optimization which is rightly known as the root of all evil. Please. Your app will talk to the network, likely run a database query which is like thousands or millions of times slower than a function call. Further, even if there is a measurable difference the cost of hardware which makes that difference go away is very likely to be smaller and much smaller at that than the cost of the engineering hours wasted during maintenance when wrestling with code which was written with a "function calls are expensive" mindset.

This doesn't mean you don't need to worry about performance and scalability but even that is going to be much easier if you have a well structured code.

Does the water need to be that cold? I would think the cooling can be accomplished just by having a large enough water tank and possibly a radiator and fan so that the thermal mass would prevent your body from heating it up for the 8 hours or so you spend on bed.
It is a rocket. The biggest difference with the Falcon 9 first stage is that this one is about 6 times as big (diameter of 9m vs 3.7m), and that catching it with the tower requires a much higher precision in landing location. The drone ships that Falcon 9 lands on are about 90 x 50 meter. To catch it with the tower, they need to be accurate to within a few meters.

The big advantage of catching it with the tower is that it'll (eventually) allow them to put another Starship on top, refuel and launch again within hours, as opposed to the weeks it currently takes for Falcon 9.
It’s been a relief to find a platform where I can ask questions without the fear of being humiliated

Half joking, but I am pretty tired of SO pedantry.
It's more precise than landing on the ground, there is coordination with the tower required, it is way bigger than Falcon 9.

That comment bought back memories, I never noticed how CM looked similar to one of those old Borland stroke fonts.
Wondering about wider implications. If technical interactions reduce online, how about RL and how do we rate a human competence against an AI once society gets a habit from asking an AI first? Will we start to constantly question human advice or responses and what does that do to the human condition.

I am active in a few specialized fields and already I have to defined my advice against poorly crafted prompt responses.
Doubtful. It's probably just incompetence, rather than malice.

The incident almost certainly cost Zendesk more in (according to the gist) lost contracts and reputational damage than it would've cost to pay the security researcher a bounty.
Running the service could involve a more efficient division of labor. Think of Adam Smith's pin factory. I don't know how many manual steps are involved in sequencing. I live in a town with a couple of big diagnostic test labs, and they are very much organized as an assembly line. They hire hundreds of technicians and scientists. There's also modern quality control, which isn't going to happen in an academic lab.

PDF has a proper "page" abstraction. Printing to paper is a first class feature, not an bolted-on afterthought.

A page in an electronic viewer will print out a to a nice and neat page of paper looking exactly the same.

Until someone invents interactive paper, the interactivity in PDF will be limited to "augmentation" of things like filling in forms, that don't interfere with the usefulness of a printed form of the document.
It was revealing to me how long it took me to work it out.

Only half true as maybe reasoning and actual understanding is not the strength of LLMs but it is fascinating that they actually can produce good info from everything they have read - unlike me who only read a fraction of that. Maybe dumb, but good memory.

So I think future AI has to read also everything if it is used like ChatGPT these days by average people to ask for advice about almost anything.

I think we’re in agreement. It’s going to take next generation architecture to address the flaws where the LLM often can’t even correct its mistake when it’s pointed out as with the strawberry example.

I still think transformers and LLMs will likely remain as some component within that next gen architecture vs something completely alien.

Easy to keep saying this, but SO was useful because it wasn't wild west.
The practical problem is that, out of the box, SQLlite runs inside a single program.

If you use, say, PostgreSQL, any number of web server processes and batch processes can run at any time and connect to the database and the integrity of your data is ensured. If you want to do some administration or analysis just connect with psql or DBeaver.

SQLLite on the other hand is a library that runs inside a single program. If you want to add a table or do some analysis you have to shut your web server down!.

It is not the hits per day that matter so much as the analysis, administration and management requirements. If it is an application just a few people use you can shut it down to admin, but if it has 15-25k users you will certainly inconvenience some.
The Shuttle consisted of the shuttle (orbiter) itself, the external tank (not reusable), and the two boosters which could be reused after ocean recovery. The orbiter itself was slow and expensive to reuse since (among other things) all the heat shield tiles were inspected and 30-100 replaced between each launch. I don't know how much work was done to the engines between launches, but SpaceX's parts and cost reduction on the Raptor engine have to give it an advantage there.

StarShip consists of the Super Heavy booster that we saw "caught" today, and the StarShip (orbiter) itself. Having the booster return to launch site vs requiring ocean recovery should potentially increase cadence and reduce cost of reuse. StarShip is also meant to be reusable, although it remains to be seen how that will pan out. On the previous flight there was burn through from inadequate heat shielding - maybe we'll see an improvement with today's vehicle. I'd expect SpaceX to iteratively arrive at a quicker and more cost effective orbiter reuse procedure than NASA had with the shuttle, but how quick remains to be seen. Of course they are planning many of these to go on one-way trips to Mars rather than being reused.

Sometimes online forums are the only place where you can find solutions for niche situations and edge cases. Tricks which would have been very difficult to figure out on your own. LLMs can train on the official documentation of tools l/libraries but they can't experiment and figure out solutions to weird problems which are unfortunately very common in tech industry. If people stop sharing such solutions with others, it might become a big problem.
Spacex might be a private company, but this project is funded by NASA, meaning the American taxpayer. Approved by a person whose last act was this approval before leaving NASA and joining Spacex (effectively putting money in their own pocket).

It is also yet to be seen how Starship will ever be profitable (outside of spending government money), who is going to pay for those launches and for what purpose. Other than Starlink, of course.

I think the problem isn't specific to SO. Text-based communication with strangers lacks two crucial emotional filters. Before speaking, a person anticipates the listener's reaction and adjusts what they say accordingly. After speaking, they pay attention to the listener's reaction to update their understanding for the future.

Without seeing faces, people just don't do this very well.

The problem is that launch costs went down fast but satellite costs haven't gone down as fast and still have long development timelines. The other problem is the market for satellite services hasn't developed as fast as anticipated, except for starlink.

That doesn't seem plausible. Hard exercise increases oxidative stress and yet we have pretty good evidence that frequent hard exercise is correlated with longer lifespan.

This is a nonsense conspiracy theory. It popped up based mostly off conserving a single man’s connection to 2001 SpaceX.

Does Starship enable brilliant pebbles? Sure. But that’s because it provides easy access to space. Starlink could be described as a network of communication ‘pebbles’, as could Starshield, SpaceX’s actual military contract [1].

(Starship provides a technology platform for rapid launch. That’s more valuable for missile defence than orbital nonsense for intercepting warheads by way of predictable and observable plane-change manoeuvres.)

Obviously there are exceptions but human-wrong answers tend to be more subtly wrong whereas hallucinated answers are just baffling and nonsensical.
This comment makes the most sense to me in this thread.

Further, IMO, sure it's a bug that one can say they control support@company.com. But IMO the real issue is lousy, permissive authorisation that gives access to anything simply by virtue of controlling a @company.com mail. Surely some HR/tech person, when an employee is being onboarded, should be enabling access to some core systems (probably by adding them to a group), and the default state for an account with no groups should be no access.

In any large enough organisation, IME there's a lot of ways to get a @org.com email, and too many people/systems have the ability to create an email than a single centralised IT team.
The results I've seen, and please correct me if my knowledge is wrong / outdated, are that modest physical activity (i.e. not gym, but more than our sedentary lifestyles) regularly nets most of the health benefit.

Ergo, we don't need to turn our jobs or built environment into Ninja Warrior.

We just need to build it to encourage that modest amount of activity.

Infinite parallel universe is nonsensical to me. It is an unprovable metaphysical contraption that offers nothing of value besides copium for the less fortunate and the gullible among us.

Also, it has nothing to do with luck as being discussed here.
It’s possible for a company to completely misidentify their ICP, typically because it’s what they want their ICP to be rather than who it is. It sounds like that happened in your case: they wanted to target a customer that either didn’t exist or who their contracting services were a shockingly poor fit for.
> Starship should bring those costs below $1000.

It might even bring the costs below $100/kg.
There was a lot of smoke coming out of the bottom after the catch. I was worried about an internal fire but it’s since stopped. The glow from the engine mount on re-entry was amazing. The fire on landing had me worried too I was expecting it to grow but put itself out eventually.

What an amazing morning!

I'm not sure how critical "catching" the booster is to reusability, but it does save weight by not needing legs for landing, and perhaps the booster suffers less stress this way?

Note that the booster is not really being "caught" although this is the word it seems we're stuck with. It's really more like landing on the arms, since it throttles to a hover at that point.
I have a theory that the medical community has a somewhat antagonistic view on mind-affecting drugs that work and have genuine positive effects - it's that healthy and/or undiagnosed people will take said drugs willingly, as they provide their positive effects for healthy individuals, and they'll instantly get labeled as abusable drugs, whose consumption is tied to heavy criminal charges. This reputation and the accompanying legal red tape makes medical research into said compounds very difficult.

An ironclad rule for medically approved drugs is that no fun is allowed - approved drugs must not have any positive effects on mood or well-being or must come with such heavy side effects that no sane healthy person would willingly take them.

For some reason, the medical profession considers the enhancement of one's quality of life beyond some arbitrarily chosen 'healthy' baseline to be forbidden, and is in cahoots with the executive branch to gatekeep it at all costs.
I gotta say though, Typst is powerful enough to implement a custom line spacing. Using the measure command you can get the height of the current font and use that to automatically convert. It's just cumbersome.

Partially. They have a fixed-price contract to land humans on the Moon, and notably got that contract because they severely undercut the other bids and were the only bid that actually fit within the available budget: they bid $2.94B, while Blue Origin bid $5.99B and Dynetics $9.08B.

That 3 billion is also much less than what they're spending on the project.
So in your video, the drone kept hovering over the Trader Joe's parking lot while you talked. What would it have done if you'd truly forgotten about it and not told it where to land?
Violating the terms (gpl) and taking over the name/identity/accreditation are what's stealing. Not merely using or redistributing.

I had to google around a bit, as there are multiple settings on how large tables are handled, I suggest that you give Typst a try, you can build a working prototype in no time

ncurses lets you move the cursor to arbitrary positions, and also lets you hide it. And you can disable echo, so you can type without the cursor having any influence on what you see. This means you can treat the terminal cursor as though it's a software-rendered cursor in a GUI app and apply all the same rules. But nobody considered doing this when Emacs was first written (maybe it wasn't possible then), so the assumption that the cursor is always on screen is difficult to change.
It is common for Starship prototypes to have uncontrolled fires, but it is obviously not a good thing.

For example, prototype number 10 exploded 8 minutes after landing [1] because of a seemingly insignificant fire at the bottom.

After today's flight there was a long lasting fire in the engine section, with occasional flaming pieces of plumbing raining down from the rocket. Examining the aftermath should help SpaceX to understand what improvements need to be made to prevent this from happening.

I wonder if there is some way to combine this with a language model, or somehow have the language model in the same latent space or something.

Is that was vision-language models already do? Somehow all of the language should be grounded in the world model. For models like Gemini that can answer questions about video, it must have some level of this grounding already.

I don't understand how this stuff works, but compressing everything to one dimension as in a language model for processing seems inefficient. The reason our language is serial is because we can only make one sound at a time.

But suppose the "game" trained on was a structural engineering tool. The user asks about some scenario for a structure and somehow that language is converted to an input visualization of the "game state". Maybe some constraints to be solved for are encoded also somehow as part of that initial state.

Then when it's solved (by an agent trained through reinforcement learning that uses each dreamed game state as input?), the result "game state" is converted somehow back into language and combined with the original user query to provide an answer.

But if I understand properly, the biggest utility of this is that there is a network that understands how the world works, and that part of the network can be utilized for predicting useful actions or maybe answering questions etc. ?

You and I have very different definitions of 10x developers. 10x developers are just people who can achieve vastly superior performance. Rarely is there any announcement, bragging, or bravado that comes with this. On the contrary most 10x developers tend to want to hide their performance up until they are ready to quit.

Its not like they are going to get paid 10x more for over achieving. There is nothing flashy to this. Instead they will be reassigned to other people's problems on top of their own work. So, its best to just keep it to themselves and over achieve as necessary to do less work, because they will get paid the same either way.
Absolutely, and I’ve worked with (and tried to model myself on) people who hire people smarter than they are. If nothing else, management is itself a skill and many highly competent doers have little interest in management. And that’s ok! But I have seen way too many managers-promoting-managers and ignoring doers along the way.
Yeah but they did pass some flame down much of the tower. Pretty quick though, probably just cleaned it with fire.

The critical differences between Falcon 9 first stage and the Starship booster is that Starship booster lands using 3 engines rather than 1, and can throttle them down much further. 3 vs 1 gives Starship more directional control for precise landing (critical for this "catch" maneuver), and throttling allows it to hover, as it does right before the "catch".
Trust is important for high performers. Trusted to get the job done and to make the best decisions.
