Yes, commonly referred to as a “battery emulator” in EE labs for mobile devices. Some are lab grade test equipment from big name vendors, and some are home-grown concoctions which use a power supply, capacitors, and adjustable load to shunt the power when the device tries to “charge” the battery. If a battery charging circuit is running, it’s generally not enough to just provide a DC power supply, it actually needs to be able to both source and sink current. But if the battery charger can be disabled, then a high current power supply, lots of capacitors, and a good short connection can be enough to replace a battery for a phone/tablet.

Oh, you could tame animals to make them your pets.

One Halloween I logged into UO, and my character had been transformed into a deer, as some kind of a sick joke! All my inventory was gone, and all I could do was deer stuff.

Then some bastard came along and TAMED ME. That totally sucked! I had to follow him around obediently all day. I guess I'm lucky he didn't skin me and make me into leather armor.
I'm using gcc under Ubuntu/WSL on Windows, so it may be some compiler thing.

But nevertheless, thank you for taking the time to follow up on this, because it is a very interesting subject to me personally and a lot has been learned through efforts such as yours, in this thread.

Other cats simply ignored that smell.

I don't disagree with that. The problem is evolving it into a market saturated with general purpose devices and subscription services. That's something that Sony and Nintendo shrugged off.

Lets throw this on the table: I actually played Fortnite on my iPad the other day via XBox Live streaming. It was perfectly playable, with an XBox controller streaming to my TV. And I didn't have to buy a Switch, PS4 or any up front cost on games at all.

Before they finally patched the hole, I used to enjoy running through crowds of high level monsters in dungeons to get a whole parade of them chasing me, then quickly casting a portal into the middle of town, usually next to the bank, then ducking behind the portal without going through, as the whole line of monsters walked towards me and popped through the portal and into town!

You are comparing two different time scales and two different spectra.

The lightning finishes in microseconds. The flame front speed of well-mixed gasoline/air mixture is about 16.5 m/s (see https://en.wikipedia.org/wiki/Flame_speed ) so 6 microseconds to cross that 0.1 mm.

Seems comparable, right? But that's the entire length of the lighting bolt in microseconds, not just one patch. Plus, the 0.1mm calculation assumed only gasoline, not a gasoline/air mixture with a 12:1 compression. Any guidance from a real-life comparison would be affected by the diffusion speed of oxygen. If it takes significantly longer to burn the same energy then the intensity (energy/time) will be significantly lower.

In addition, the spectra are different. Have you ever seen a fuel-based camping lantern? They use a mantle to make the light significantly brighter. (See https://www.youtube.com/watch?v=F3rncxf4Or8 for details). This mean the visible light from burning fuel isn't a good guide for the amount of visible light which can be generated from the same amount of energy.

How do you produce 10W to power an electric bike? 10W is a laughable amount of power, just get rid of the electrics and pedal a bit.
10W is barely enough to charge a phone these days. Anything that gets moderately hot while in use is consuming more than 10W.

This is kinda naive to wish for - tar has applications that reach beyond stuffing a BLOB containing other BLOBs and some metadata into a seekable file somewhere, such as archiving data to magnetic tape/LTO.

And even if you develop the perfect archive format that happens to nail every possible use-case 100% (which you won't, because there just are too many), you will STILL have to deal with compressed and archived artifacts which accumulated over the last six or so decades in various places.

Worse is when some UX designers decide to improve a product that works well as it is only to make it worse and convoluted. This has been my experience more often than not, and my solution is to simply stop using such products. It sucks.
Some websites suggest the average lightning bolt has 5 GJ of energy, which is 5000x what this page quotes. I think someone has done a math error.

> Pro cyclists can reach up to 400 Watt in short bursts

I heard pro cyclists can reach up to 2kW. I managed to make 500W on a rowing machine for 5 minutes, but I'm a couch potato. I believe 400W is a normal rate for cyclists. When you are sitting, your body already produces about 100W of heat.
Agreed, this is also my timeline for Flutter web becoming a more serious contender.

There are one or two other technologies/ standards that are an important piece of the puzzle like the accessibility object model to start to decouple accessibility from the rendered DOM interface for example and allow canvas based interfaces to become better supported.

But I follow a lot of that stuff pretty closely and 2-3 years seems like more than enough time, a bunch of it is probably slated to happen as early as this year (WebGPU behind a flag already on all browsers I believe, WasmGC under active development in all browsers, dart already has a functional WASM compiler and a new graphics engine ready to go and take advantage of it etc..)

Strapi closes $31M Series B led by CRV
Really? They've sold >107 million units of the Switch/Switch lite/Switch OLED so far.

That makes the Switch one of the best selling consoles ever made - it beats the Wii, the original PlayStation, the PS3, the GBA. It's edging towards the PS4 and the GB & GBC.

According to their own stats, each of those consoles has an average of ~8 games sold (excluding download only titles, so the real value is higher).

Even though it might not work for you or your family, I think that's good evidence that Nintendo have a formula that works pretty well for them - those kinds of sales figures are not indicative of a company in crisis to me.

Coming from web I gave serious shot to React Native for quite sometime but I learned the hard way that it can go only so far in mobile app development.

> Rust doesn’t solve the problem of abstraction layer impedance mismatches causing ownership to be dropped only to be reacquired at the next level

The expression of what C++ does here in Rust is awkward and, I think, nobody has proposed it because you'd never write that. Basically C++ char* is a raw pointer. Rust does have those, but you'd never use them in this context.

What you would use is either the borrowed slice reference &str or the owning String type, but in both cases we have an owned object and there's our crucial difference. If you've got the owned String, and I needed an owned String, I should ask for your owned String, and we're done.

In C++ "dropping" ownership as you describe is no big deal, the C++ design doesn't care, but in Rust if you actually drop(foo) it's gone. The references to it can't out-live that, if it's gone then they're gone. If you write code that gives away references and then tries to drop the thing they're references to, Rust will object that this is nonsense, because it is nonsense, you need to ensure those references are gone before dropping the thing they refer to.

As a result I feel you're greatly under-estimating the ergonomic difference.
True, but there are limits. It’s surprising how many apps and webpages I use that are just straight up slow - things that should load instantly instead take a second or two. The web is a good application for this to some extent since there are other latencies that make this less noticeable, but they still exist.

Anything written to be performant is immediately noticeable - things just happen when you click a button. Dev time > runtime, but I’d argue some runtimes are so slow they begin to eat into user time too.

Genuine question : do you feel that FOSS is at a disadvantage when it comes to security/threat prevention? The hypothesis would be that potential attackers are able to gain the advantage by being able to fully review the source in advance and leverage potential weaknesses. (Or worse, contribute to the project and inject weaknesses)
When will someone stop caring about money and make something like this again? Surely, the spending power of people who played UO is more than insignificant, it could at least break even.

Charge $20 a month (roughly the same as $9.95 a month in 1997), focus on creating a world and MUD-level game complexity. Stand on the shoulders of giants and get in front of exploits (which were basically new at the time).

I feel like people are starving for this type of experience again, but forced to feed on the scraps (WoW and clones).

Mortal Online was one such attempt recently, but it wasn't enough of a playable world. And any time someone creates a hardcore MMO, it attracts almost only PKs (because there are so few hardcore MMOs). There needs to be a healthy mix of people, of all Bartle types.

I can't remember where I read it, but I believe Raph Koster once said something like "Nobody pays $9.95 a month to get killed repeatedly by another player". While that is true, I also don't want to pay 10 bucks a month to only win. Surely, there's a way to blend these experiences. It feels very similar to the OSR vs trad gaming schism in D&D...

> I learn a tremendous amount from Twitter and vastly prefer it to needing to buy a book

Is this "learning"? You sure get entertained, quick-and-easy-to-digest facts, good for short attention spans, and 5-10 minutes later you go back to whatever else you were doing. Or hop on the next "educative" twitter thread or somesuch. But have you actually learned something?

If I ask you a week later to summarize your new insights, will you be able to? Will you even remember that you read about this? I sometimes find an old tab in a browser window that I had forgotten to close a while back. I skim through the contents, oh right! That thing! That was interesting! Turns out, a twitter thread, barely a week old, about something interesting, "I really learned something!", but I had already forgotten about it again, and if somebody had asked, I'd mainly have answered "Oh yeah there was this thing, don't remember the details, or the conclusion, or anything really, but I think I read something the other day", which is just hot air.

We should not treat such twitter threads as educational content. They are short-term entertainment, and good at that, but in essence not very different from a tiktok clip of some girl dancing on the beach.

If you really want to learn something, you need to invest time. By reading a book, by discussing with knowledgeable people, by trying something out yourself and/or trying to put your own words down. This takes energy, patience, time and can be frustrating at times. But twitter threads can't solve this for you.
That doesn't sound great; a couple of questions spring to mind:

Is there information from the students about the reason(s) that they don't want to consume school-provided meals?

And is there a sense of how often this is occurring? (is it a particular problem in some locations and not others, or widespread?)
I'm not sure there's a "they" here; IIRC this is and always has been one man project by Igor Pavlov, who incidentally didn't just write the software, but also created the LZMA algorithm which has had an absurdly long run as one of the world-leading general purpose compression algorithms.

I like the site + product idea, but the demo fails to show me anything interesting except a floating comment. So I can't yet see the value of the tool.

The files you've chosen to use don't appear to show any difference between iteration 1 and 2, so one of your major features doesn't do anything. Is that a bug, or accidental? (I'm using Firefox 101 on MacOS 11.4).

My personal dumb suggestion: give a few demos, showing off the very worst points of code review hell, and how crocodile fixes each one. Make it a game. E.g.

"You're halfway through a large code review, and Sally has just added 2 new commits, ugh. Challenge: find the button to see the new additions, then decide if you want to include them in your current review, or review this iteration first and the new additions separately."

"Simon has just added a merge commit that fucks everything up, all the files look weird. Challenge: there's a way you can trivially see that the PR before this extra commit was looking great."

"You can spot a new method that was introduced, and you'd like to see the places where it's being called, but that's a lot of scrolling back and forth. Challenge: find how to show code hints on a selected piece of text"

That was my experience with RN. The React ecosystem is nice but the RN specific libraries that come with native components have been nightmares.

This includes libraries from major companies that were incomplete (as in didn't implement functionality that they claimed to have in the repository readme file), badly broken, and nearly no documentation.

Once I realized how common this was, I just implemented my own native components when required. React Native itself was and is very good, good enough to make it worth using despite the minefield ecosystem.

Certainly not saying it's not successful for its time. But this is about the future and the whole dedicated device model and expensive games are rapidly becoming a dead end. The tablet and phone gaming market has a lot of overlap now and people expect there to be market parity with that.

I suspect Nintendo will inevitably end up like Sega and be a games publisher on other platforms. And there's nothing wrong with that. People like Nintendo because of the software. The only reason the hardware sells is because it's the only way to get the software.
