There are many, many, many ways to provide enrichment for a cat without letting them outside

Sure, I could buy some live mice for her to ‘play’ with, but I don’t want that mess inside my house.

Wow, it looks so much prettier today. All thanks to climate improvement.

It’s probably his handlers telling him to refuse.

Can’t believe no one has suggested this yet: Melodies of Life from Final Fantasy IX

Sounds like a case of X-Y problem

Fat binaries contain both ARM and x86 code, but I was referring to Rosetta, which is used for x86-only binaries.

Rosetta does translation of x86 to ARM, both AOT and JIT. It does translate to normal ARM code, the only dependency on a Apple-specific custom ARM extension is that the M-series processors have a special mode that implements x86-like strong memory ordering. This means Rosetta does not have to figure out where to place memory barriers, this allows for much better performance.

So when running translated code Apple Silicon is basically an ARM CPU with an x86 memory model.

it's transpiling the x86 code to ARM on the fly. I honestly would have thought it wasn't possible

Apple’s been doing it for years. They try to do ahead of time transpiling wherever they can but they also do it on-the-fly for things like JITed code.

Anything multiplayer.

Front left keys, front right phone. No wallet, I pretty much exclusively use Apple Pay on my watch.

By now this has to qualify as elder abuse.

I can imagine wanting to learn a newer, more modern language than python.

I blame Apple (and then Samsung for copying Apple) for stealing this form factor from us.

Neither prevents other companies from making a phone with this form factor. It probably disappeared due to lack of market demand.

And yet, I’ve never run into RAM problems on iPhones, both as a user and as a developer. On iOS an app can use almost all the RAM if needed, as long as your app is running in the foreground. Android by contrast is much stingier with RAM, especially with Java/Kotlin apps. There are some hard limits on how much RAM you can actually use and it’s a small fractIon of the total amount. The actual limit is set by the manufacturer and differs per device, Android itself only guarantees a minimum of 16MB per app.

The reason is probably because Android is much more lenient with letting stuff run in the background so it needs to limit the per-app memory usage.

Those apps also use more RAM than an equivalent iOS app, simply because they run on a garbage-collected runtime. With a GC there is a trade-off between performance and memory usage. A GC always wastes memory, as memory isn’t freed immediately once no longer in use. It’s only freed when the GC runs. If you run it very often you waste little RAM at the cost of performance (all the CPU cycles used by the GC) if you run it at large intervals you waste a lot of RAM (because you let a lot of ‘garbage’ accumulate before cleaning it up). In general, to achieve similar performance to non-GC’d code you need to tune it so it uses about 4 times as much RAM. The actual overhead depends on how Google tuned the GC in ART combined with the behavior of specific apps.

Note that this only applies to apps running in ART, many system components like the web browser are written in C++ and don’t suffer from this inefficiency. But it does mean Android both uses more RAM than iOS while at the same time giving apps less RAM to actually use.

It basically comes down to different architectural choices made by Google and Apple.

It's not hard to target the older models, with iOS it's mostly just a few small tweaks.

It depends what you are doing. Targeting the iPhone 7’s GPU can be quite a PITA.

Upgrade your dinosaur of a phone.

Several things that made the SD card annoying to developers.

First: you could not install an APK on the SD card (probably due to DRM reasons). So if you had a larger app and you wanted users to be able to take advantage of the additional storage offered by the SD card you could not do this simply by having a large APK. (Note that this also was true for phones that had no removable SD card but had internal memory that presented itself as ‘external storage’).

On some phones the normal storage was so small that any larger app had to leverage the external storage to be able to even fit (we’re talking 10+ years ago). The way to do this was using so-called ‘expansion files’. These were additional data files, up to 2GB a piece, that could be installed on the external storage. These came with some additional difficulties.

• They were pure data files, so they could not contain any executable code. They were just big binary blobs, so none of the Android built-in mechanisms for loading assets depending on screen density, screen size and all that stuff worked. You had to do it all by hand.
• Since they were just binary blobs, you had to do any organization inside the files yourself. For example, they could be large ZIP files but you had to do all the ZIP handling yourself. Compared to normal APKs that are also ZIP files but where you can just load stuff from the APK archive and it’s all handled by the framework.
• The expansion files were separate from the APK. The Play Store did try to automatically download them if your app had expansion files, but this was not guaranteed. Furthermore, because they live on an SD card they could disappear at any moment. Your app needed additional logic to deal with this, code to re-download the files if they were missing, code to handle errors during the download, UI to show the download progress, etc.

Another problem with SD cards was the huge variety in quality of SD cards. Phones internal storage is reasonably fast, but you never know what kind of cheap-ass yanky SD card the users installed in their phone. This caused all kinds of performance problems in more demanding apps and as a developer you had to deal with the fall-out (bad reviews, support requests, etc.)

• Losing SD Expansion sucks; they should bring this back. Only reason they stopped this is greed.

Fuck that noise. SD expansion was a terrible idea and I’m glad it’s gone. There are so many problems introduced by removable storage, it was a terrible PITA to deal with as a developer. One of Google’s dumbest ideas in early Android. Good. Fucking. Riddance.

Doesn’t matter either way because everyone uses WhatsApp anyway.

RCS will never be able to compete with either because it’s a GSMA standard. Apple or Meta can think of a cool new feature, add it to their client and roll it out to all their users with the next update.

If they want to add a new feature to RCS, the GSMA (An organization with over 1500 members) will have to form a committee, they can then talk about their conflicting interestes for a few years before writing down a new version of the standard, then dozens of clients and servers at hundreds of different operators need to be upgraded before everyone can use the new feature. Due to this bullshit RCS will never be able to keep up.

Not entirely true… the American Android users care about it;

Then I guess it’s nice for both of them that iOS will support RCS.

Literally no one cares about RCS.
