Linux/Unix just trust that if you want something persisted with certainty you'll do an fsync, if you do it will absolutely guarantee you're not losing that. It will absolutely make…

As for kernel panics, with iOS likely sharing most if not all of it's kernel code with macOS I'd be surprised if Apple hasn't had an iPhone macOS build since before they released t…

Interestingly it seems rust only does full overflow checking in debug builds: https://huonw.github.io/blog/2016/04/myths-and-legends-about...

Yeah I know about 1 e.g. also MicroPython, no idea if that's used outside DIY though. I agree about rust but I would think that with much stronger type safety and static compilatio…

Instead of fusing them, shouldn't it be possible to speculate that it will not overflow, process the check on a separate slow path and do a roll back in case it did overflow?

I wonder how this interacts with branch prediction. Since overflows should happen very rarely I guess the branch on overflow should almost always predict as non taken. So wouldn't …

I would argue that the stable syscall interfaces is one of the main drivers behind Linux success. Containers as we know them would be quite different if they needed to somehow merg…

Maybe I'm missing something but e.g. on the Android clock you can dismiss an upcoming alarm. So now if you wake up, dismiss it and it never rings that kind of proofs you really wok…

I think the most expensive isn't the address translation itself but TLB housekeeping when mappings get remapped or invalidated. This is especially true with virtualization where th…

Afaic the upcoming Porsche Taycan has a two speed transmission. In the Taycan it's used for more efficiency at >160 kph or so something an American car really doesn't need and it c…

I deleted my account when they purposefully made their Linux version not launch on any other FS than ext4. I use btrfs and that supports all the features they use, still Dropbox re…

I hear this claim almost every day yet its been years since I've actually felt my normal work computers being slow. Hell, even booting an OS in an emulator running in a browser pro…

Well at the very least running in a container gives you filesystem and network and PID space isolation, optionally also user namespace isolation.

Docker also has support for user namespaces which makes it so that the root inside the container is e.g. nobody outside. In general I'd say docker (with user namespaces) is quite a…

Alacritty is pretty great, especially if you enable use of the new ConPTY API (needs Windows 19H1)

That's almost certainly "rosy past" bias. Even Aristoteles is said to have complained about the terrible youth.

SpaceX is landing rocket stages on a drone ship after having them drop from 7400 km/h at 100 km altitude. JPL has a city car sized rover craned from a hovering lander on Mars and D…

I'm such a space enthusiast and I'd absolutely love a Biodome 3. That said, I think that people tend to confuse "sustainable colony" and "self-sustaining colony". If it ever comes …

But without saying "this is a test for Mars" such a colony will never be built. Even in Antarctica shipping in supplies once a year is just sooo much easier.

I don't see why this realization should be regarded as a counter argument to establishing a Mars colony. It's really really hard and a lot of problems need to be solved. The most i…

I really don't use Windows all that often but when I do I now really prefer to use WSL and a proper OpenSSH or mosh. Even running in the default Terminal it's still nicer than PuTT…

But Ibuprofen isn't necessary for most of its users survival and is still much cheaper. More importantly, with both a social safety net and public health care close to no one in Ge…

They're definitely not the only ones, saw a presentation on a University team working on this just yesterday. After all, vision is the only system for which we know that it can be …

Why shouldn't a camera based system be able to do that. Dirt for example won't easily match up in a stereo vision system and even then dirt on a lense has a pretty specific look

Why on earth would you want to install 32 bit Python 2.7 if you already have 64 bit Python 2.7?
