Package for OpenCV4

Hi, just started to prepare a packge for `qimgv` [1], but it has a dependency to OpenCV-4, and current available version of OpenCV in Guix repository is 3.4.3. just wanted to know, if there is a plan to upgrade OpenCV to version 4? since I had a try and it seems that OpenCV-4 needs more tasks

I could fix up some of the new homepages. We've already seen some Gnu related package losses like gdal. I think SWH adoption for packages may want to be moved from as packages are added to as packages are updated -- just to have a regular, low overhead, but still slow move to SWH. On Mon, May

Providing a Guix System images catalog.

Hello, To build a Guix System image, one needs to pick an operating system file and call "guix system disk-image my-os.scm" to get an image. While this works fine on desktop, this is more tricky for the embedded devices. Which operating system to select in "examples" folder? What's the

Now that I actually have some experience using SQLite from writing the Guix Build Coordinator, I can actually see potential ways to improve bits of Cuirass. The intention here is to start to address the performance of db-get-builds, which I think can be quite slow. This commit does several

Hi Zimoun, The HTTP headers of the page indicate that the file hasn't changed since 1970. This is a bug. That incorrect date breaks repology.org trying to track guix packages. On Mon, May 25, 2020, 06:42 zimoun wrote: > Dear Josh, > > On Sun, 24 May 2020 at 21:26, Josh Marshall > wrote: > >

Hi Chris, the docs at https://www.sqlite.org/pragma.html#pragma_optimize suggest to run "PRAGMA optimize" at the end of the connection, or periodically--not at the beginning. That makes sense since it has to be able to see which queries are emitted in order to know what to optimize. Also, docs

[PATCH] cuirass: Perform some database "optimization" at startup.

Add a "optimize" step that occurs when starting up the main Curiass process. Currently this does two things, but could be extended to do more. The "PRAGMA optimize;" command prompts SQLite to ANALYZE tables where that might help. The "PRAGMA wal_checkpoint(TRUNCATE);" command has SQLite process
