How to make hydrogen production cheaper and easier: include an atomic reactor component.

Huh?

I’d be interested in hearing about some scenario where this actually costs less, given the cost of building anything nuclear in 2026.

This site seems to auto-translate itself into my browser’s locale. Interesting approach but probably not the right choice if your audience is the tech crowd. I’m perfectly fluent in English, thank you very much.

I suppose it’s a clue that the whole thing was copy-edited or written using LLM. Not reading it.

Well, you’re saying that after you already learned how to do it.

I don’t know if we’re reading the same article? The linked one states very plainly:

”Idempotency is about the effect

An operation is idempotent if applying it once or many times has the same intended effect.”

You’ll notice they raised prices in Japan by A Lot, but the US price is only up $50.

Classic class warfare. ”Buy on eBay”. Sure worked for the bolsheviks!

Presumably someone claimed it as ”AI” by listing it on the registry.

Not that I’ve seen. Every time I rent a recent model year, they have the lane keeping assist feature but it only works when you enable adaptive cruise control.

But maybe that’s what you meant?

It’s not exactly a back door. It’s a fake radio cell, mimicking your network provider and acting like a man in the middle. In that sense, it’s like a stingray. The differences are

1. The Stingray eavesdrops, but avoids interfering with user traffic

2. The stingray is operated by law enforcement, not by fraudsters looking to steal your money

Is it possible to prove security properties about a web application?

I don’t think I’ve insinuated any threats. WCAG are guidelines. It’s a great idea to follow them if you want your content to be consumed, but as you say most jurisdictions would only mandate accessibility for certain actors, not for everyone. Me, I have no idea what jurisdiction the OP is in, or who he/she is, or whether WCAG would be a compliance issue to them. I just used that term as a clue/hint that there are frameworks that can help guide web authors towards good practices. Like how WCAG 2.2 specifies a minimum contrast level. Nobody knows all of this stuff by default, we all have to learn it. Gotta assume good intentions and just point them towards the tools available.

I don’t know, I got 140 upvotes on a nitpick so I think others agree with me it’s hard to read.

Like this, by word of mouth. That’s how Apple has done UI design since they stopped printing paper manuals.

- ctrl-shift-. to show hidden files on macOS - pull down to see search box (iOS 18) - swipe from top right corner for flashlight button - swipe up from lower middle for home screen

Etc, etc

Yes, it’s a great workaround but website owners should not make me do that.

To the author: please use a darker font. Preferably black.

I’m only in my 40’s, I don’t require glasses (yet) and I have to actively squint to read your site on mobile. Safari, iPhone.

I’m pretty sure you’re under the permitted contrast levels under WCAG.

Namespacing is great; look at how Notepad++ was hacked. They were sharing a non-namespaced deployment with other applications, IIRC.

I’m thinking even simple containers have automatic restarts. I wouldn’t deploy to prod using ”docker start” but I wouldn’t look askance at someone using “docker compose” for that purpose.

I think his argument is that the functionality is unnecessary. You don’t need dynamic service scaling because your single-instance service has such high capacity to begin with.

I guess it’s all about knowing when to re-engineer the solution for scale. And the answer is rarely ”up front”.

I mean, you’re not wrong about the facts, but it’s also pretty trivial to migrate the data from SQLite into a separate Postgres server later, if it turns out you do need those features after all. But most of the time, you don’t.
