#lzma — Public Fediverse posts

Live and recent posts from across the Fediverse tagged #lzma, aggregated by home.social.

  1. #zstd 1.5.7 is out and it's honestly quite amazing.

    Highlights for me are:

    - ~10% faster at small block sizes common in databases(=filesystems?)
    - Limited multi-threading by default. (You could already enable it manually; this only concerns the defaults.)
    - A new --max flag that inches zstd closer to #lzma/#xz. We'll need to see more testing on how close exactly but it's impressive they managed to broaden the range this far in a single format.

  2. BZip3

    在 Hacker News 上看到 BZip3 的連結:「Bzip3: A spiritual successor to BZip2 (github.com/kspalaiologos)」。

    雖然名字看起來與 bzip2 有關,但看起來是不同的人弄出來的東西,不過有些經典的演算法有留下來用,像是 Burrows-Wheeler transform。

    另外值得一提的是,bzip2 是 1996 年出的 (不過 1.0 大約是 2000 年時出的),BZip3 的第一個 release 在 2022 年,這段時間也累積了不少有趣的演算法可以用。

    無損壓縮中如果期望有比較的壓縮率,目前比較常用的應該是 LZMA 類的演算法 (差不多是 2001 年出現的),用的工具通常會是 X

    "(...) Through good-cop/bad-cop tactics, software developers have been pressured into subtly hidden vulnerabilities. How can we avoid this in the future?
    .
    1️⃣ Simplification/reduction of programs and dependencies
    2️⃣ More appreciation and support for the open source developers
    3️⃣ Better control, but without burdening developers
    4️⃣ More applied training

    What are your ideas? Looking forward to feedback!

  6. Hey I need to get LZMA/LZMA2 lib source, where do I get one that's untouched by the scam person?
