Streamio FFMPEG VS DistorteD

I found this https://github.com/streamio/streamio-ffmpeg but I don't know to integrate it into my rails app!

While we can work with FFmpeg directly, we’re going to use a gem to make our interaction with FFmpeg a little simpler: streamio-ffmpeg

I wrote a Ruby library that attempts to be good at this https://github.com/okeeblow/DistorteD/tree/NEW%E2%80%85SENSA...

Just a style thing. I find it less visually overwhelming when every statement that contributes a true/false is visually contiguous. You can see it in context here if curious: https://github.com/okeeblow/DistorteD/blob/NEW%E2%80%85SENSA...

I experienced a heisenbug exactly like this in Ruby when trying to `while case Ractor::receive`: https://github.com/okeeblow/DistorteD/blob/dd2a99285072982d3...

Here's one that sounds like exactly the sort of example you had in mind: https://github.com/okeeblow/DistorteD/tree/NEW%E2%80%85SENSA...

Disclaimer: mine :)

This resulted in a huge memory-usage win since I can load data on the fly without blocking other queries. The last pre-Ractorized version of CYO allocated around ~200k objects in 7MiB and retained ~17k in 2MiB of memory. The first Ractorized version allocated ~20k objects in 2MiB and retained ~2.5k objects in ~260KiB of memory. See revision 8c88844b9d256ecc447f6818ab427284b5636cb9 for the initial conversion.

This is the use-case for me. Here's an actual example of a Struct I will probably convert to Data in the file-identification library I've been working on. Right now they just have their `#to_a` overridden to disable some of their annoying automatic Enumerable behavior: https://github.com/okeeblow/DistorteD/blob/dd2a99285072982d3...

In addition to this resource and UK's equivalent (PRONOM/DROID, also mentioned in the linked post), I've found ArchiveTeam's wiki to be very useful for obscure file format details: http://fileformats.archiveteam.org/

The `shared-mime-info` database from freedesktop-dot-org is probably more worthy of contribution than these government-backed databases, at least in terms of number-of-end-users. New type definitions in their database will improve the entire Linux/BSD ecosystem (both desktop and server!) because it's consumed not only by fd.o's own `update-mime-database` utility but by many language-specific type-identification libraries too https://gitlab.freedesktop.org/xdg/shared-mime-info/-/blob/m...

…including (shameless plug) the new Ractor-based Ruby type library I've been working on in the wake of the `mimemagic` drama earlier this year: https://github.com/okeeblow/DistorteD/tree/NEW%E2%80%85SENSA...

Ruby also lets you build programs like this as of 3.0, using Ractor#send / Ractor::receive https://docs.ruby-lang.org/en/master/doc/ractor_md.html#labe...

It’s still pretty new so a lot of the Gem ecosystem hasn’t caught up yet (e.g. C extensions need to be explicitly opted-in as Ractor-safe), but I built a new “MIME::Types” library replacement with it recently and have enjoyed very few teething issues: https://github.com/okeeblow/DistorteD/blob/NEW%E2%80%85SENSA...

I considered switching to Hugo a while back but ended up sticking with Jekyll for the extensibility, like a few others have said. I'm particularly interested in image thumbnailing and format conversion since so many of my posts are image-heavy. I often found that to be my biggest and most frequent barrier to writing since plain text only goes so far on the modern web.

In Hugo, every solution I've seen uses a custom shortcode or custom Markdown image template-rendering hook along with Hugo's build-in image resizing. Many posts even suggest converting image resources to different formats with an external tool. It does seem like the image handling situation in Hugo is improving since it just gained WebP processing support in addition to JPEG: https://gohugo.io/news/0.83.0-relnotes/

Jekyll plugins offer way more power than a shortcode ('include' in Jekyll-speak) can, like how the author of the OP is using Jekyll-Picture-Tag. I've been working on my own similar plugin to handle converting and embedding my site's images, videos, SVGs, PDFs, text files, fonts and weird retro computer formats, etc. For example I can embed an SVG using standard Markdown syntax like `` and get a tag with the SVG plus rasterized JPG+WebP+AVIF+whatever at multiple sizes all totally seamlessly: https://github.com/okeeblow/DistorteD

Very happy the existence of Hugo lit a fire under the Jekyll team to work on speed though :)

> It works at first, but you end up wanting to design your own custom SSG once you run up against something that goes against your mental model of how things should work.

There is a middle ground. I hit this point in Jekyll when I wanted Insanely Great image thumbnailing that no extant Jekyll plugin could provide, ended up writing my own tool to do that, but didn't want to duplicate the rest of Jekyll's functionality too. It's kiiinda hacky and I probably should propose the interface changes upstream if I keep doing this, but a very light monkey-patch lets my tool pretend to be a Jekyll::StaticFile that just happens to write out many separate files: https://github.com/okeeblow/DistorteD/blob/master/DistorteD-...
