Then, in another terminal window, we use curl to hit the endpoint:
Project mention: Why Bloat Is Still Software's Biggest Vulnerability | news.ycombinator.com | 2024-02-09You can create the webview using each platforms native GUI toolkit and setup JS communication yourself OR you can use a lightweight library that does it for [1] (search its README for language "bindings").

Project mention: Radicle: Open-Source, Peer-to-Peer, GitHub Alternative | news.ycombinator.com | 2024-03-05Everything that is replicated on the network is stored as a Git object, using the libgit2[0] library. This library uses hardened SHA-1 internally, which is called sha1dc (for "detect collision").

No smartphone these days gives you access at the mass storage level anymore (because it causes issues for concurrent access from the phone and computer, because there's often encryption etc.), so the underlying file system in this scenario is completely irrelevant and has no bearing on you being able to access the phone's data on Linux.
Android uses MTP or PTP (can't remember which) for that type of access, while iOS uses something proprietary, but there's a Linux implementation that worked reasonably well for me last time I had a Linux laptop: https://libimobiledevice.org/
Project mention: Show HN: Nano-web, a low latency one binary webserver designed for serving SPAs | news.ycombinator.com | 2024-03-25
In my example the table stores the hash codes themselves instead of the keys (because the hash function is invertible)
Oh, I see, right. If determining the home bucket is trivial, then the back-shifting method is great. The issue is just that it’s not as much of a general-purpose solution as it may initially seem.
“With a different algorithm (Robin Hood or bidirectional linear probing), the load factor can be kept well over 90% with good performance, as the benchmarks in the same repo demonstrate.”
I’ve seen the 90% claim made several times in literature on Robin Hood hash tables. In my experience, the claim is a bit exaggerated, although I suppose it depends on what our idea of “good performance” is. See these benchmarks, which again go up to a maximum load factor of 0.95 (Although boost and Absl forcibly grow/rehash at 0.85-0.9):
https://strong-starlight-4ea0ed.netlify.app/
Tsl, Martinus, and CC are all Robin Hood tables (https://github.com/Tessil/robin-map, https://github.com/martinus/robin-hood-hashing, and https://github.com/JacksonAllan/CC, respectively). Absl and Boost are the well-known SIMD-based hash tables. Khash (https://github.com/attractivechaos/klib/blob/master/khash.h) is, I think, an ordinary open-addressing table using quadratic probing. Fastmap is a new, yet-to-be-published design that is fundamentally similar to bytell (https://www.youtube.com/watch?v=M2fKMP47slQ) but also incorporates some aspects of the aforementioned SIMD maps (it caches a 4-bit fragment of the hash code to avoid most key comparisons).
As you can see, all the Robin Hood maps spike upwards dramatically as the load factor gets high, becoming as much as 5-6 times slower at 0.95 vs 0.5 in one of the benchmarks (uint64_t key, 256-bit struct value: Total time to erase 1000 existing elements with N elements in map). Only the SIMD maps (with Boost being the better performer) and Fastmap appear mostly immune to load factor in all benchmarks, although the SIMD maps do - I believe - use tombstones for deletion.
I’ve only read briefly about bi-directional linear probing – never experimented with it.

Project mention: Show HN: Pzip- blazing fast concurrent zip archiver and extractor | news.ycombinator.com | 2023-09-24Please note that allowing for 2% bigger resulting file could mean huge speedup in these circumstances even with the same compression routines, seeing these benchmarks of zlib and zlib-ng for different compression levels:
https://github.com/zlib-ng/zlib-ng/discussions/871
IMO the fair comparison of the real speed improvement brought by a new program is only between the almost identical resulting compressed sizes.
Project mention: How dot disable usbmuxd so I can transfer photos from my iphone? | /r/pop_os | 2023-06-06Popos seems to come with usbmuxd, which is a cool idea because it allows you to view the "documents" on an iphone (look into each app's sandbox), use USB tethering and theoretically transfer photos. You're supposed to get two icons when an iphone is connected. One for documents, and another for photos. I'm not getting the photos one and I have some photos I want to transfer.
You'll likely need to make use of the `ssh` or `ssh2` crate, depending on whether you want to use `libssh` or `libssh2` (two different libraries) for the SSH protocol. Then, if you choose `libssh`, you'll need to port https://github.com/codinn/libssh/blob/master/examples/sshnetcat.c and if you choose `libssh` you'll need to port https://github.com/libssh2/libssh2/blob/master/example/tcpip-forward.c to Rust.
Project mention: Expat (XML parser) is understaffed and needs funding | news.ycombinator.com | 2024-04-03I would not have found the call for funding help until they pointed out here:
https://github.com/libexpat/libexpat/blob/R_2_6_2/expat/Chan...
I don't understand why there isn't a donate button on the README / website to support development of this and instead it's hidden somewhere.
Maintainers it is perfectly OK to ask the public to donate or ask for sponsorships.
If xz taught any anything we don't want to be in that situation again.
