homebrew-core VS FFmpeg

Is disabling the compromised repo the typical GitHub policy? My concern is there are monorepos used by package managers, like brew, that are a collection of thousands of projects [1]. These monorepos seem like a prime target for attack and if GitHub disables one because a malicious commit was merged then you've taken down an entire ecosystem.

> Correct. Though we do not appear to be affected, this revert was done out of an abundance of caution.

This is the same with a binary though. And with homebrew, you can't follow patches or flags used or if they change.

definitely be careful about using fortune in a corporate environment or public space if you don't know what dat files you are using or you might just get an extremely unwelcome surprise.

I was practicing a presentation and used to use "fortune" all the time. I forget exactly what it output but I remember being absolutely mortified about what could have happened if that had popped up during an internal company tech talk.

Kudos to brew for keeping unsuspecting people safe

I'm sorry to be asking this as I find it a bit silly, but it's blocking my PR [3], so could a few of you star the project on Github [1] to get my PR to run?

GPL2

Since FFmpeg is GPL2, doesn’t that require CompressX to disclose its source code?

IANAL, apologies if I miss understand license requirements.

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".

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+.

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.

To run the demo locally, be sure to have Python 3.11 and FFmpeg installed.
