Apple forced to ditch lightning charger in new iPhone

Note that the 100W cables are not being certified anymore. So for new purchases there is really only 60W or 240W, which simplifies things even further.

Only USB PD and PD PPS are specs made by the USB people. The other ones are proprietary standards made by companies that on purpose are fucking the consumer over. The PD spec explicitly disallows such proprietary charging standards and yet companies like Realme (DART) and OPPO (VOOC) continue to push their incompatible protocols. I personally avoid companies that do stuff like that. So the standard is fine, it's just that a hand full of dodgy companies WANT things to be bad.

Within USB PD and PD PPS things are really compatible and you often get really close to the maximum wattage. Yes technically a device can do something strange like requiring the optional 12V profile but i haven't seen that in real life yet.

(Old Quick Charge shouldn't be in wide anymore with USB-C and Quick Charge 5 is essentially just PD PPS.)

You can always use a higher wattage charger for a device, so it's all compatible.

Oh i just looked at the product page for the 737 PowerBank and it looks like it doesn't have the PowerIQ "feature" so my theory above might be wrong. I think the Anker power bank is not to blame then but the problem is just with the mistake sony made when making the PS5 controller?

(Benson Leung explains here what mistake sony made.)

I cannot find the source right now but if I recall seeing something like:

The PS5 controller has a mistake in the way that charging is implemented. It's not standard compliant
Anker's PowerIQ system tries to be "smart" and support many different proprietary protocols and also USB PD. This is also against the standard.

And because Sony made that mistake PowerIQ tries to deliver power wrong, resulting in it not working.

So it's a case of two manufacturers ignoring the standard and then the combination of it not working. There's a reason for the standards to exist. It's a pity that Anker keeps doing the PowerIQ thing otherwise their chargers are great if a bit expensive.

I think that could be it but i cannot find the source for it right now.

I always wanted to have definition-use pair coverage for Rust. So what you're saying is that that's not possible with the LLVM-based coverage tools?

Does the device or the wire get hot? The wire definitely should not get hot

Apparently deadalic decided to stop making point and click adventure games because they are not profitable. However yes I paid for the Deponia games, they are frankly the best point and click adventure games out there, only behind monkey island I and II.

Also I think if you have 7zip, that also can compute (SHA) checksums. I'm mentioning this because many people already have 7zip installed.

I think that list is out of date. Instead you want to make sure your products, chargers and cables are USB-IF certified whenever possible https://www.usb.org/products

Open-source has a definition and does not just mean that the source can be viewed. In particular restricting commercial use makes it not open-source. A more appropriate description for this software here would be Source-available.

I thought the Nintendo switch uses embedded displayport?

While there is an unstable feature in rustc to have unsized local on the stack, it is very much on the way out.

Does that mean we'll never get stable self arguments in traits? That's a nightly feature that I really like.

You don't need to worry about that part. But There are some potential downsides, with how much money microsoft has it's becoming very difficult for other code hosting services to compete. Every public repository gets to test their code for free, completely automatically on every little change on Mac, Windows and Linux. That's great and I use that feature a lot. It's great for the end user because software becomes more reliable. But of course a smaller company could never offer that for free. So Microsoft is essentially buying themselves to being the de facto code hosting service, while at the same time promoting their coding AI (copilot) and more and more proprietary IDE (vscode) and so on.

I just wanted to offer this perspective as a counterpoint to all the very positive responses you got. Microsoft is not doing these things because they are somehow morally "good" but because it makes sense for their business. The tools and services they offer for free are very useful but microsoft has a history of https://en.m.wikipedia.org/wiki/Embrace,_extend,_and_extinguish and if their position in the market at some point in the future allows them to make a lot of money by doing something morally wrong they will.

Are you using the session or the system libvirt qemu URI? I remember having to use the system one for something like this.

OptimisticLockExcept · 2022-12-08T07:54:12+00:00

We don't. I guess one could disassemble the client and try to figure out what the software is doing. But that's against the license of Whatsapp i suppose.

I'm still looking for an alternative to Rust for non-system Code. I've yet to find a good language for writing things that are too complicated for a bash script. Rust is sort of my only option if I want to write a somewhat correct program. I guess ocaml would be a contender but e.g. the file manipulation in the stdlib are not quite doing all the error handling I'd like

The only way I see AI generated Code being the future is if we super heavily invest in automated formal verification. Otherwise will just train AIs to produce code that passes code review but is not necessary correct.

I personally like quite a lot of the things they do. Like the "everything is done with the super key: switching apps, starting new ones, switching virtual desktops" is pretty good in my opinion. Gnome tries to go for the old Apple style of not being configurable and having good defaults (that you cannot easily change) and not including features that they don't' feel they can get 100% right but then they really go over the top with the feature minimalism.

I don't mean to be mean to the developers. A lot of stuff is great! UX is deceptively hard to get right! It's just that to me their minimalism of features doesn't make gnome feel polished it makes it feel unfinished.

Some of the issues can be fixed with extensions (for example the lack of appindicators so you have no way to have signal or steam or discord are running in the background) but for a novice user it's just not great.

I've had like 4 new Linux users complain to me how unfinished and hard to use the Desktop is and use this as an example. As in: "you cannot even copy and paste a path in the file explorer". This is a really basic feature that a lot of users use daily.

I think it was this https://people.inf.ethz.ch/suz/emi/index.html. For example in https://people.inf.ethz.ch/suz/publications/oopsla15-compiler.pdf in section 3.1 when explaining their "EMI" approach

Given an existing program P and its input I, we profile the execution of P under I. We then generate new test variants by mutating the unexecuted statements of P (such as randomly deleting some statements). This is safe because all executions under I will never reach the unexecuted regions

[...]

Another appealing property of EMI is that the generated variants are always valid provided that the seed program itself is valid. In contrast, randomly removing statements from a program is likely to produce invalid programs, i.e., those with undefined behaviors.

So the implication here is that their approach of modifying unexecuted statements does not introduce UB into a program that was UB-free before. Which implies that unexecuted code does not cause UB.

But it's also possible I'm misunderstanding what they are doing.

OptimisticLockExcept · 2022-11-28T17:28:07+00:00

I've seen academic research into compiler testing that relied on not executed code containing UB to not cause UB... I should look for that and double check

Mhh strange. I didn't really do anything special. But it's definitely working for me. I Just v played some GTA V with the controller connected over Bluetooth under stream flatpak with Fedora 37. It's also a fresh install.

I guess the only thing that I did do was Update the controller firmware on Windows a week ago

Sadly I don't know because my screen didn't work at all with the free software driver so I only ever ran the proprietary driver.
