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.

Ask HN: Best to store, index and categorize audio recordings
If you're doing a pipelined bulk processing pass to add metadata tags after extracting them via Speech to text, or have delimited notes in a text file, or ... etc.
You might find ExifTool useful.
It's pure commandline (with a few third party GUI's IIRC) multiplatform and purpose built to display, edit, add media tags to all sorts of AV files.

Cleaning up my 200GB iCloud with some JavaScript
> Any method that I've found to clean them up (exporting the originals, deleting them from the library, and then re-importing the JPEGs only seems easiest) will lose all of the years of metadata that I've built up in the library.
The open source tool osxphotos (https://github.com/RhetTbull/osxphotos) can help with this. You can export the JPEG images while preserving metadata using the thrid-party exiftool utility:
`osxphotos export /path/to/export --has-raw --skip-raw --exiftool`
This exports all images that have a raw pair but skips the raw component then uses exiftool (https://exiftool.org/) to write the metadata (keywords, etc.) to the exported JPEG files. You can then re-import these into photos either by dragging them or by running `osxphotos import /path/to/export/*`
Both the export and import commands have many other options for controlling export directory, etc. `osxphotos help export` or `osxphotos docs` to open docs in browser. (Disclaimer: I'm the author of osxphotos)

Locationator: Access Apple's Reverse Geocoding service from the command line, Services menu
Locationator also comes with an optional CLI that can be used to perform reverse geocoding on images from the command line or perform the reverse geocoding and then write the location data to the file's XMP metadata using exiftool. It also comes with two services for doing the same from the Finder or other apps using the Services menu.

JPEG XL: How It Started, How It’s Going
I think TIFF has some unique features that makes it more prone to certain security issues[1] compared to other formats, such as storing absolute file offsets instead of relative offsets. So I am not sure TIFF is a good container format, but many camera raws are TIFF-based for some reason.[2]

Show HN: CompressX, my FFmpeg wrapper for macOS, made $9k in the last 4 months
GPL2
Since FFmpeg is GPL2, doesn’t that require CompressX to disclose its source code?
IANAL, apologies if I miss understand license requirements.

Writing x86 SIMD using x86inc.asm (2017)
This turns out to be a lot of assembly macros to help write one x86 assembly. https://github.com/FFmpeg/FFmpeg/blob/master/libavutil/x86/x...
The sibling comment recommending compiler intrinsics is probably the best way to go for writing SIMD code. A mixture of `` style types and intrinsics to specify instructions is a solid 90% solution compared to assembly.
If you want that last 10%, I think macros are putting the emphasis in the wrong place. They're a somewhat easy way to build up a language abstraction which will work if held carefully, but I'm confident the dev experience using this abstraction when you write invalid code will be deeply confusing.
I would suggest to write a parser instead of the macros. That'll tell you clearly when the syntax is invalid (though possibly not with much precision) and it'll give you a place to put semantic analysis for where valid syntax encodes nonsense. Do the equivalent of the macro expansions on the parsed tree instead of on the text. Emit asm as the "back end".

Video Generation with Python
You might have heard of FFMPEG or ImageMagick for image and video edition in a programmatic way. MoviePy is a Python module for video editing (Python wrapper for FFMPEG and ImageMagick). It provides functions for cutting, concatenations, title insertions, video compositing, video processing, and the creation of custom effects. It can read and write common video and audio formats and be run on any platform with Python 2.7 or 3+.

11 Ways to Optimize Your Website
There are many cloud-based tools and websites that can convert your images, but the problem with these tools is that you usually have to upload the files for them to be processed, and some of their services are not free. In this article, I'd like to introduce a piece of software called FFmpeg, which allows you convert the images locally with one simple command.
