The performance of blake3 multithreaded is very impressive:

hmac-sha256 1.00 GB 0.327s <-- with hw accelerated sha256

blake2b-256 1.00 GB 0.952s <-- pure sw, used in borg 1.x

blake3 1.00 GB 0.442s <-- pure sw, single-threaded

blake3-mt 1.00 GB 0.078s <-- pure sw, with MT.

Have pushed 0.9.5-dev branch to codeberg of foxing ( https://codeberg.org/aenertia/foxing/src/branch/0.9.5-dev ) in preparation for release tagging. A LOT of features and a couple of bug-fixes now the packet/file processing engine has stabilized ; including Semantic Routing to Parsers for Metadata Extraction and in-path Binary analysis using local ORT/BERT models ; letting you get semantic search powers for free when you copy something with foxingd/fxcp #linux #filesystem #bert #vectordb #postgres #xfs #stratis #blake3 #localllm

`foxing` (formerly xfs-mirror) aspires to be a production-grade, eBPF-powered replication engine for Linux filesystems (XFS, Btrfs, F2FS, Ext4). It captures filesystem events in the kernel and replays them asynchronously on a target directory, providing near real-time mirroring with robust consis...

πŸ“¦ Efficient file syncing for massive datasets? Forget classic rsync!

⚑ #BLAKE3 hashes instead of timestamps – hash 70GB in just ~20 seconds thanks to multithreading across all CPU cores

#DevOps #Linux #SysAdmin #OpenSource #FileSync

πŸ“Š Algorithm comparison for 70GB:
- BLAKE3: ~20 seconds
- MD5: ~1.5 minutes
- SHA256: ~4.5 minutes

πŸ” The trick: Create a hash baseline, compare with `comm -13`, then use `rsync --files-from` to transfer only actually changed files

Research topic of the day: Choosing a #hashfunction for 2030 and beyond - https://kerkour.com/fast-secure-hash-function-sha256-sha512-sha3-blake3

TLDR: #blake3 is cool & let's hope it picks up steam, #sha512 is the winner for integrating into current projects.

...what I really cannot comprehend is why there is no #BEP to migrate #BitTorrent to #CDC and #BLAKE3, and I guess I can't (won't) ask because last time I checked signing up to their mailing list required a #Google account

Today I got to know that #nix 2.27 added #blake3 support and proper submodules and lfs support to #flakes! πŸŽ‰

Other than supporting legacy systems or implementing cryptographic password functions that *should* be slow, why aren't your teams using GNU or BSD tar with #zstd compression and #xxHash or #Blake3 checksums yet? If time is money, please stop wasting either with legacy algorithms when there are faster, more secure, and more trusted options currently available.

For #BLAKE3

$ brew install b3sum

then

$ find . -type f -exec b3sum {} + > checksums.txt
