When performing OCR, some of the Tesseract settings perform better than
others on a variety of different workloads, but they mostly take
~negligible incremental time to run compared to the overhead of running
the ImageMagick filters.
After this commit, we try using all three of the current Tesseract
models (classic, LSTM, and classic+LSTM) to generate output text. This
fixes chromium-90's tests at release-20.09, and should make cases where
you're looking for *specific* text better, with the tradeoff of running
Tesseract multiple times.
To make it sensible to cherrypick this into release-20.09, this doesn't
change the existing API surface for the test driver. In particular,
get_screen_text continues to have the existing behaviour.
Remove old CUDA toolkits (and corresponding CuDNN versions).
- Not supported by upstream anymore.
- We do not use them in nixpkgs.
- We do not test or actively maintain them.
- Anything but ancient GPUs is supported by newer toolkits.
Fixes #107131.
As the only consequence of isSystemUser is that if the uid is null then
it's allocated below 500, if a user has uid = something below 500 then
we don't require isSystemUser to be set.
Motivation: https://github.com/NixOS/nixpkgs/issues/112647
The 5.10 series is the next longterm version of the linux kernel and
I've been using it on multiple x86_64 machines ever since it came out.
I think it is time to switch over the default now, so we get some
additional testing in time for NixOS 21.05.
Formatting has been neglected. Running `make` would format dozens
of files, which is a great way of scaring away newcomers and those
with less git experience. It would also annoy the heck out of
regular contributors.
The purpose of formatting is to avoid a small annoyance, so it
should not become a big annoyance that makes people give up on
their work.
- Write a `mkDerivation` and `mkDerivationWith` function for gnuradio,
like qt5.
- qradiolink, gqrx: Use gnuradio's callPackage and mkDerivation.
- Use gnuradio.callPackage to define all gnuradio.pkgs.
- Move all gnuradio packages expressions to pkgs/development/gnuradio-modules/ -
modeled after Python's.
- Add more paths to gnuradio's wrapper - add the extra packages as
python modules, and add their executables with proper env vars
wrapping.
