Is there a way to run podman as non-root but with a privileged helper (or some caps) for proper bridged network setup?

Note that that kind of research was only possible on the (smaller) open models. When the new models are proprietary ones then outsiders can't do that kind of analysis. If they had regenerated the tokenization dictionary to match the tr

> At that point, does it keep scaling or is there an S curve where 100x more data and compute only leads to a 2x improvement? Careful with the scales. 2x improvement could be interpreted from 80% human performance to 160% human performan

That PR is about buggy or niche systems. VMs lying about their clocks, CPUs with faulty firmware revisions, kernel bugs. Rust is just going the extra mile to uphold its guarantee even when the OS fails to do its job. It would have been legi

Few things need atime at all, even fewer things need synchronous durability guarantees for atime (I'm not aware of any). So writing it out in the background (either when evicting disk cache or after 24h) while keeping the in-memory rep

Basic atomic filesystem operations support consensus numbers[0] 1 or 2 (via rename and RENAME_EXCHANGE, respectively), but for some concurrent algorithms one needs higher ones. File locks are the only way to get those (if we ignore IPC), an

Windows is slow due to all the filter drivers used by antivirus, custom FS drivers and other stuff. And the lack of a dentry cache. Basically all the reasons why WSL1 is slow. On linux you'll get slowdowns too if you have some online a

If one uses an offline password manager then you want the stored passwords to be approximately as secure as memorized passwords. So how do you deal with emergency family access to memorized information in the deceased person's brain? S

If numpy uses runtime detection of available SIMD instructions while rust is only compiled with the x86-64 baseline (which only includes SSE2) then compiling the module with `RUSTFLAGS=-Ctarget-cpu=native` might provide some additional perf

Argon2 can be used as KDF, not just as a password hash in an authentication database.

Use an offline password manager, avoid SaaS. Make sure it's secured with Argon2 and burns a a few seconds of compute to unlock. Use hardware MFA tokens for your most critical accounts. You could also tie individual copies of the databa

JSON cannot be efficient for binary data or even utf8 strings because it needs escaping which means you can't have a zero-copy implementation. CBOR is better in that regard, yeah.

Having C functions isn't all that much better. You have replaced a crufty text format with crufty data structures full of paddings, unions, bitfields, VLAs, unaligned nested structs and other crazy stuff. Look at ioctls or cmsg. With C

This is fairly basic functionality. Windows and wlroots-based compositors have it at least. I'm reasonably certain that other major compositors have it too.

Many data-/number-crunching C libraries already do dynamic-link-time or runtime cpu feature detection and select appropriate implementations. E.g. glibc already has bunch of specialized assembly impls for many of the string operations

Many string search impls are adaptive and use different algorithms depending on needle and haystack lengths and possibly also contents of the needle. E.g. https://github.com/BurntSushi/memchr#user-content-algorithms...

The upside is that babies get to interact with the environment they're training on. Image models can't move the camera a few cm to the right if they're interested in the perspective of a particular scene.

Some of the AVX512 instructions are nice additions though, even if you only use it on YMM or XMM registers. All the masked instructions make it much simpler to vectorize loops over variable amounts of data without special treatment for th
