I just spent two whole days refactoring and improving my jjlab.net website.
One thing I had to think very carefully about for my modeling was the class/instance distinction for various things, you can see my notes below.
So channels have shows, and shows have features.
A series has segments, and segments have a video.
A series is an instance of a show, and a segment is an instance of a feature.
Everything is easy when you know how!
I have my Linux kernel sources setup like this:
-------------------
Fri Jun 14 00:35:24 [bash:5.2.15 jobs:0 error:0 time:2449]

Remote branch:

-------------------
The scripts/clang-tools/gen_compile_commands.py runs just fine:
------------------- Fri Jun 14 00:35:28 [bash:5.2.15 jobs:0 error:0 time:2453] jj5@virtuoso:/home/jj5/repo/git/git.kernel.org/torvalds-linux $ scripts/clang-tools/gen_compile_commands.py -------------------
But there is a problem with some unknown clang options, as you can see here:
So I wrote this collection of sed scripts to delete the problematic options:
-------------------

-------------------
Bug fixed! Thanks to my mates on IRC for helping me fix this one. This clangd extension for VS Code seems to work really well.
p.s. another possible solution is here.
More than you ever wanted to know about the ELF format: ELF and ABI Standards.
My friend sent me this:
It pretty much forced me to write spiral.php and spiral.sh to generate this:

UPDATE: this problem was solved by installing some packages. The relevant hint is highlighted in red below.
This is the salt state I used to install dependencies on my Debian 12 system:
rockbox-dev-tools:
pkg.latest:
- pkgs:
- texinfo
- texi2html
- automake
- autotools-dev
- libtool
- libtool-bin
- autoconf
- flex
- bison
- libisl-dev
- libgmp-dev
- libmpc-dev
- libmpfr-dev
I am following these instructions: https://git.rockbox.org/cgit/rockbox.git/tree/docs/README and am having this problem:

UPDATE: the solution to this problem was to install the package ‘libtool-bin’.
I am following these instructions: https://git.rockbox.org/cgit/rockbox.git/tree/docs/README and am having this problem:

I did install the ‘libtool’ package on my Debian system, but there is no ‘libtool’ command, only ‘libtoolize’.
Today I had a read of the Linux kernel coding style. Eight character indents and brace on new-line for functions and no braces for single line conditionals… yuck. :P
