Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

SQLite VFS for ZSTD seekable format
This VFS will read a sqlite file after it has been compressed using [zstd seekable format](https://github.com/facebook/zstd/blob/dev/contrib/seekable_f...). Built to support read-only databases for full-text search. Benchmarks are provided in README.

Chrome Feature: ZSTD Content-Encoding
Of course, you may get different results with another dataset.
gzip (zlib -6) [ratio=32%] [compr=35Mo/s] [dec=407Mo/s]
zstd (zstd -2) [ratio=32%] [compr=356Mo/s] [dec=1067Mo/s]
NB1: The default for zstd is -3, but the table only had -2. The difference is probably small. The range is 1-22 for zstd and 1-9 for gzip.
NB2: The default program for gzip (at least with Debian) is the executable from zlib. With my workflows, libdeflate-gzip iscompatible and noticably faster.
NB3: This benchmark is 2 years old. The latest releases of zstd are much better, see https://github.com/facebook/zstd/releases
For a high compression, according to this benchmark xz can do slightly better, if you're willing to pay a 10× penalty on decompression.
xz -9 [ratio=23%] [compr=2.6Mo/s] [dec=88Mo/s]
zstd -9 [ratio=23%] [compr=2.6Mo/s] [dec=88Mo/s]

Optimizating Rabin-Karp Hashing
Compression, synchronization and backup systems often use rolling hash to implement "content-defined chunking", an effective form of deduplication.
In optimized implementations, Rabin-Karp is likely to be the bottleneck. See for instance https://github.com/facebook/zstd/pull/2483 which replaces a Rabin-Karp variant by a >2x faster Gear-Hashing.

I've done that experiment with zstd before.

Not sure about brotli though.

Ask HN: What is your approach for managing personal digital assets?
I religiously use Google contacts. It's the simplest way to keep people contacts up to date on Android.
I archive all important documents in specific folders by subject and date. This is backed up to back blaze with restic. https://restic.net/
I use https://ente.io for pictures. I convinced my wife to use it, and she agreed to auto share her photos so I don't nag her for copies. It had simple import from Facebook and Google.
I also keep extensive journals, which really helps to tie it all together. I can basically grep for hangouts, conversations, etc.
I also separate work journal from personal, and have essentially a journal for each project. https://jodavaho.io/tags/bullet-journal.html for how.
I religiously use Google calendar for all plans, you can easily search it for past events to get dates.
I also use monicahq for some notes about things I should remember about people but the habit never stuck.

Duplicity
After Borg, I switched to Restic:
https://restic.net/
AFAIK, the only difference is that Restic doesn't require Restic installed on the remote server, so you can efficiently backup to things like S3 or FTP. Other than that, both are fantastic.

I'm curious, too. I know they've had some issues in the past:
https://github.com/restic/restic/issues/3268#issuecomment-78...
On the other hand, I tested around 15,000 backups last year (multiple hourly backups, daily tests) and they all passed.

I use and recommend restic. I use it for about 60 machines on my LAN, and it's absolutely fantastic.
