Rails Erd VS FFmpeg

I've been using a simpler version of this https://github.com/voormedia/rails-erd but it seems neat that this comes with a web app and a query language.

Graphviz

Use the rails-erd gem to generate an ERD: http://voormedia.github.io/rails-erd/

Entity Relationship Diagrams (ERDs) are super useful for visualizing databases. For an ERD example, or to see how to make one, see this gem. Though note that gem is only for rails 3-5.

You should take a look at rails-erd, it is really easy to set up and works quite well

At my work we've got a 10-year-old Rails app (originally started as Rails 3), rake stats says we're now over 100kloc (non-test). We've got a huge amount of complexity and cross-dependencies (not to mention, probably-dead code), and the majority of our test suite runtime (about 40h non-parallelized) is in cucumber because developers can't get a clear view of the level of the app they're dealing with, and I suppose don't feel they can trust the lower layers of the application. Running rails-erd on it generates the very definition of spaghetti, it's gross.

This PR fix the build

FFmpeg (https://ffmpeg.org/)

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.
