Many people seem weirdly suspicious about Google's #Brotli compression while being weirdly chill about Facebook's #ZSTD, to the point of commenting on posts about Brotli compression being added to things to the effect of, "This is a conspiracy by Google, they clearly should've chosen ZSTD instead". What's up with that? Is Google really so much less scary than 𝘍𝘢𝘤𝘦𝘣𝘰𝘰𝘬?
(This is a subtweet about a certain HN post about Brotli compression coming to #PDF)
Carrot Cache, a memory-optimized Java caching solution with Zstandard dictionary compression, is now available on Maven Central. This release brings efficient caching to Java projects, enhancing performance and reducing memory usage. #Java #Caching #OpenSource #MavenCentral #Zstandard #Programming #VulaiProgramming

Instead, annotations are stored in special-purpose annotate functions and **evaluated
only when necessary** (except if from __future__ import annotations is used).

🌘 Zstandard 長範圍模式優化基因組序列壓縮效果顯著，無需換行符
➤ 提升基因組數據壓縮效率的關鍵：Zstandard 長範圍模式與無換行符策略
✤ https://log.bede.im/2025/09/12/zstandard-long-range-genomes.html
本文探討了 Zstandard 壓縮軟體中的「長範圍模式」（--long）功能，特別是其在處理基因組序列數據時的表現。作者發現，透過移除 FASTA 檔案中原有的換行符，並結合 --long 模式和更大的窗口大小設定（如 --long=31），能顯著提升壓縮比，使基因組數據從原本的數 TiB 壓縮至數百 GiB，其壓縮比逼近專門的 DNA 序列壓縮工具，同時保持了接近 Zstandard 預設模式的壓縮速度。文章建議，在壓縮基因組序列前，移除序列內的換行符是發揮 --long 模式最大效益的關鍵。
+ 原來換行符對壓縮影響這麼大！這篇實測數據很紮實，感謝作者的分享，以後處理基因組數據就知道怎麼優化了。

Today I discovered that there is also an excellent compression format, #Zstandard (ZSTD), is fast with an excellent compression ratio, developed by #Meta, and released as #opensource
I needed to backup my files because I have to wipe my PC and reinstall #Linux. Now I have a dilemma: choosing between #antiX and #Lubuntu. I have a fairly decent computer, so I could even install a more full-featured OS, but I prefer an OS that doesn’t use too many resources.

Brand new PEP by @emmatyping to add Zstandard to the standard library:
https://peps.python.org/pep-0784/
Will it make it in to 3.14 before the feature freeze on 2025-05-06? It'll be close but it's possible!
The PEP also suggests namespacing the other compression libraries lzma, bz2 and zlib, with a 10-year deprecation for the old names.
