Speaking of not existing:

All the hydrogen generation/splitting facilities (it all comes from methane, right oil company astroturfer?)

I forget, did you guys fix the various fundamental laws of thermodynamics so that you can get hydrogen from water at high efficiency? You know, water, that ultra-stable molecule? Or should we just ship the electricity over the existing grid rather than take 30-50% losses putting it into hydrogen, physically ship it with some new fangled hydrogen tank truck, and then get the energy out?

So how much energy do you use to GET to that 1000 wh/kg? Oh right, you'll really just get it from methane or tar sands or fracking or whatever. Right oil company executive.

All the hydrogen transport infrastructure. Does hydrogen like being in tanks? I forget. Does it basically leak from everything? Hydrogen is really stable, right?

All the hydrogen refuelling stations. Wait, is hydrogen a liquid? Oh, it's a gas? man, those'll be annoying to engineer. Right, bet that's a solved problem for Joe Q public.

All the fuel cells that last longer than 100,000 miles. I forget, did you fix that little platinum problem? Right, solved problem.

Here's the real kicker: what price are you targeting with hydrogen cars and infrastructure? It'll take, what, 10 years to get close to what the electrical grid and current recharging stations offer? I mean, we have EVs like NOW. Lots of them. Hyuuuuge factories. Does the "hydrogen economy" exist yet? Right, only if you use methane? Gotcha oil company dude.

I forget, can I slap some solar panels on my roof (especially those perovskite multijuntion ones that I hope come out in a few years) and directly use that to generate hydrogen for my hydrogen car? Oh, is that a bad idea? I should just use an EV?

Don't get me wrong, hydrogen has potential to be useful. Medium/long range aviation, really long haul shipping, really long haul trucking. You know, edge cases. You know, unless synth fuels become a thing.

So just to reiterate:

1) you have no factories for a mass production car

2) you have no green production of hydrogen

3) you have no transportation infrastructure

4) you have no pumps/refueling

5) it'll take, what 10-20 years to get to where EVs are right now?

While EVs:

1) have factories / in production

2) can use any generation source, just hook it to the grid.

3) transportation? You mean the grid? Or generation at home?

4) recharging stations, while yeah, not what gas stations are, they exist and are actively being built out

5) and just to reiterate, there's been production EVs for... 15 years now?

Your little hydrogen bus system in Japan? I almost guarantee that gets chucked once cheap EV buses hit the mainstream (they don't need to go far, they do lots of stop-go so regen, it would be really nice to charge them off the grid, they will be cheap/in mass production). I mean, if you're a city, would you like supported / non-bespoke cheaper-than-ICE buses with low maintenance cost, cheap repair, or some screwy hydrogen thing?

Yeah.
FYI debit cards with a card network logo also allow chargebacks just like credit cards. So it's extremely unlikely that chargebacks had anything to do with it.

It's fairly common for cheaper gas station networks like ARCO to only accept debit cards because of the fixed fees.

"OTP cryptography" is for the most part not a thing. If you were running a spy ring and literally giving each of your agents a paper pad with numbers on them, you could print them from `getrandom` output; the `getrandom` bytes wouldn't be how that system was attacked.
Yeah, but you'd have to treat him differently and that unnecessary work. In software it's good to keep separate the things that don't need to be combined. UBI is universal so even the richest guy in a country should get it. Reducing one (some?) of his taxes and remebering to not pay him UBI is more work than just keeping those things separate.

It's worth pointing out that if you say "Go except with Rust's guarantees for thread safety", a _lot_ of the complexity comes back. You need to pull in lifetimes and move semantics and the no-mutable-aliasing rule. You need the Send and Sync traits. You probably want Deref-based smart pointers too. (And you'd need to make extensive use of the new generics features that are already in Go.)

If you know the altitude above sea level and the density is uniform then it should be possible to calculate how how much ice is below the surface and the thickness.

Sonar should be able to measure the distance from the sub to the ocean floor and the sub to the bottom of the ice above it. Add them together and you get the distance from the ice to the ocean floor.

With those two datapoints it should be possible to get an accurate estimate of the ice thickness.
High-assurance isn't really the culprit. It's more of a funding issue. If long NASA programs could save part of the first year's budget to use the second year, things would go a lot faster.

You might get hired into an overstaffed team and not do that much for a year until it's crunch time and then you're underfunded so it takes an extra year. Arguably you spent three years to achieve one year's worth of accomplishments.

Apply the Nixon test: should the public have been given access to the tapes that conclusively established Nixon’s involvement in the Watergate break-in? Most people think yes, despite them being “just” conversations.
Nothing flopped, it just never reached breakout success the way I wanted. Most things I managed to get into the top 5 of the front page of HN over the span of 8 years, whether it was a project, blog posts or products but that's just a moment in time, a few hours even, it's not success. I wish my projects had reached the point that I could have carried on working on them. The latest M3O.com, was a serverless API gateway, that honestly I thought as a product was great but never achieved the thing I set out for it to be. It was also VC funded, so even more painful that it didn't work out.

Now I'm hacking on something new, not shared it yet but let's do it.

I am unsure exactly what you are referencing with “tube-clamps”. If you mean hoop-clamps or hose-clamps, then those usually have “self-cantering” hexagonal heads as well as the slot: https://duckduckgo.com/?q=stainless+steel+hose+clamp&iar=ima...

And story has it the small battery is the reason for the pathetic performance. (9.1 seconds 0-60 speed, which is minivan levels).

The fuel cell can't produce electricity fast enough to power the engines for proper acceleration and the battery doesn't have enough buffer.

For a few of the languages I’ve added a “thoughts on this language” section in the language folder’s README, but I only started doing that after a few implementations were already finished, so it’s a bit inconsistent - maybe it’d be worth making it consistent, and writing up as a single easy-to-read webpage, and submitting that to HN :P
Why is it offensive? Over-hiring has been a thing since at least the first dot-com boom. One's managerial power is directly proportional to how many "reports" they have under them. I worked at one company that raised a decent A round. We immediately rented another office down the street, spent close to 2 million on renovations, then filled it with anyone who could spell HTML. The B round was even larger, so the cycle continued (until late 2001 or so.)
I love the optimism that congress people that oppose EVs and will use excuses like Lithium as excuses for their continued opposition (when there is no real connection to their actual opposition) would somehow magically support bipartisan plans for public transportation.

The article knows Lithium is just an excuse for the opposition and that there are deeper reasons for the opposition, but then doesn't run the political game through to its obvious conclusion that many of the root reasons for the opposition are the same root reasons for opposition to decades of public transportation projects as well. These aren't two very different groups that oppose EVs and oppose public transportation: this Venn diagram is almost a circle.
> - one click "deliver to my closest branch and I will pick it up and pay there so I don't have to muck around with online payments" option

I've started using this as much as possible, especially during christmas. You find something, "in stock", supposed to be delivered the next day or a day after, you order, then nothing one day, two days, three days, then you call, "yeah, it's still with the distributer, it'll be ready tomorrow", two more days pass, you call again, want a refund, they "cannot refund now", because the product is supposedly in the mail already, then you wait, christmas goes by, and around 15. january you get a call, that they cannot get the item you wanted, and try to upsell some either more expensive or worse option.

Now I just order for physical pickup and "pay there" option.. and if it's not there, cancelling is easy, because they don't have your money yet, and they cannot lie about the item being already sent.
> Go ahead and create, no technology is stopping anyone from doing that

Yeah, but where did I say that? That's not my point at all.

Here are my thoughts, rephrased:

- We, mankind, don't need AI to "improve" writing. This is a problem nobody has. There's a plethora of writing, both for children and for adults.

- People enjoy writing, so this isn't an activity we want to "optimize". There's no need for ChatGPT here.

- When computers take over creating everything, what is left for us humans? If/when books are being written and published by AI, sure you can go on writing for your mom & friends I guess, but something fundamental will be lost.

- When most "content" (I hate that word) is created like this, some sort of extreme Netflixization of movies and books taken to its logical consequence, we will become consumers. Isn't that depressing?

> As for asking if we need more bedtime stories - why not? Maybe it would be cool if me and my kid could use some experience we had together [...]

I do this every night with my daughter, without AI. It's called "parenting". You don't need gadgets or computers for this. ChatGPT isn't solving an actual problem in this case either.

"Computer, tell my kid a funny story about that time something fun happened to us; I think it was yesterday, it's in my mobile logs anyway."

Language is a representation medium for the world, it isn't the world itself. When we talk, we only say what can't be inferred because we assume the listener has a basic understanding of the dynamics of the world (e.g., if I push a table the things on it will also move). Having an AI watch youtube and enabling it to act out what it sees in simulation would give it that grounding. We are heading that direction. So, I agree ChatGPT is awesome. I don't believe it understands what it is saying, but it can if it trains by acting out what it sees on Youtube.

A tiny, single-header <canvas>-like 2D rasterizer for C++

More detail -- This is an STB-style single-header C++ library with no dependencies beyond the standard C++ library. In about 2300 lines of 78-column code (not counting blanks or comments), or 1300 semicolons, it implements an API based on the basic W3C <canvas> specification to draw 2D vector graphics into an image buffer:

- Strokes and fills (with antialiasing and gamma-correct blending)
- Linear and radial gradients
- Patterns (with repeat modes and bi-cubic resampling)
- Line caps and line joins (handling high curvature)
- Dash patterns and dash offsets
- Transforms
- Lines, quadratic and cubic Beziers, arcs, and rectangles
- Text (very basic, but does its own TTF font file parsing!)
- Raster images (i.e., sprites)
- Clipping (via masking)
- Compositing modes (Porter-Duff)
- Drop shadows with Gaussian blurs

I also uncovered a number of interesting browser <canvas> quirks along the way with the HTML5 port of my testing suite.
I wonder if the warranty information is correct? From some of the comments, it sounds like they do warranty service in-house for some items at least? I wonder if Apple really has that much lower % of warranty issues, or if Apple owners tend to get warranty service direct from Apple instead of going through Galaxus, and so they don't have the data on Apple products?

I used to be a fan of programmer productivity and having the best tools to express ideas in. In our case, this is not about LISP, but about being able to write 40 lines of SQL in half an hour to solve things that other people reach for 1000 lines of backend language to do. But also trying hard to identify opportunities to simplify and delete code instead of adding another layer of complexity on top every time something doesn't add up.

But I've started to wonder. In some ways I feel "our" area in the company has been a victim of our own success: By doing things in smart/efficient ways, the tasks we've done has become seen as simple, we didn't need to recruit as much, and eventually because of the low number of people occupied on the task in the organization it is seen as easier or less important and we are more vulnerable to churn than larger teams.

I've seen simpler problems getting solved in (what I think is) very inefficient ways and I used to scoff at that. But now I think what they gain is a large robust team, which can handle both churn and have more weight politically in the organization. Solving something inefficiently simply offers a way to have more people do the same task, for redundancy.

In a sense, once an organization hits a certain size it seems that efficiency in a programming language is an anti-feature. You WANT a larger set of programmers to be happily working on something just to have a larger team around the code and redundancy in people. If a programming language / environment allows you to be too efficient, then too few people get the job done and you become vulnerable.

At least, that's the best explanation I have at what's really going on in the industry.
Oh that’s exactly what I was hoping for! Thank you!

Just an educated guess (I'm in the same industry, have worked on some networking related stuff) But I think it is probably mostly network hardware and architecture. You can only improve so much from the code, the networking is where all the latency comes from.
This is unlikely to ever happen though since so much is tied to it like the permissions system and the admin. The ORM itself is central. I wouldn’t use Django unless your project depends on an RDBMS.

But you don't want to do reporting on an application's data model, that doesn't scale: as soon as you have a medium-sized business, the data will not be confined to a single application (unless that application is named SAP). Understanding the business data model is a requirement for SQL analysts anyway, and once you have the application data transformed to the business model, the business users will have no trouble understanding it.
> Electrification makes them much more economically independent.

The Japanese electric grid is so shitty you won't even believe it. They have single phase 100V power. Half the country is 50Hz and the other half 60Hz.

Their grid just plain can't handle electric cars at scale without a full and complete overhaul.
Look at the 'supported by' section.
The borrow checker is not an insignificant cost. Maybe you could imagine an incremental compilation mode that just didn't evaluate the borrow checker for faster development.

As other commenters have noted, the Go backend is extremely simplistic ("barely an optimizing compiler"). Rustc is also a lot faster in -O0 mode than any optimizing mode. But -O0 is somewhat dumber than Go's compiler. You could imagine an -O1 (or -O0.5) with compilation time vs performance tradeoff similar to Go, but it isn't there today. There's also an attempt to adopt a more simplistic backend (cranelift) into Rustc to improve codegen performance, but so far it hasn't provided much speedup.
