consolidated my linux pr process to a a repo, so that i can improve it over time :-) i tried printf first to generate substitutions for the mustache based email template but jq is needed here just purely for escaping the summary generated by git request-pull.

Sometimes it would be useful if you could have multiple Git repositories in the same clone as long as they don't share files. E..g, for separating private data.

There is an alternative for Rocksmith, which also plays its '.RS files: https://tonelib.net/jam-overview.html

This not only fixes the issue macOS but there is also a native Linux version. Further, it happened to be 60% discount :-)

Cool, my PR for rust-hex was merged:

https://github.com/KokaKiwi/rust-hex/pull/83

It adds decode_in_slice() function, which decodes the hex string within the input buffer overwriting the contents. It is with ugly but still useful for e.g., fast and constrained protocol implementations.

Just came as surprise because the PR was made almost two years ago...

I enjoyed responding this:

https://lore.kernel.org/linux-integrity/aGffUrDSjNH6w6rB@kernel.org/

Enjoyment did come like e.g, for "winning the argument". Instead it s fun to do this type of comparisons for the cause and effect of choices to the resulting binary :-) I did honestly did not know the correct answer beforehand.

Reviewing random day-by day patches can be boring. If I have some extra bandwidth this how I usually spice it up just a bit.

The fact that the issue is so trivial makes me doubtful of myself in this one:

Himmelblau is the "new Samba" really, but how fast the situation needs to be addressed is on the other hand more like in the metrics of "EFI secure boot", which was an edge case 10+ years ago.

Intune is a technology where open source community needs to be clear on that "no, microsoft, edge + a shitty daemon running on a subset of linux distributions is not acceptable".

experienced this today on a machine running debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1078608

fixed up by:
sudo rm -rv /var/lib/apt/lists/*

Linux Foundation should take Himmeblau under its Umbrella.

As of today, the project is based on reverse engineering Apple and Windows clients, as the Intune API for Linux that Edge uses in tandem with intune-portal service does not have machine authentication.

"Microsoft Intune App" is based on chain of Microsoft binaries scavenging requested data from a system (Edge and intune-portal).

This blocks essentially the management tools for organization Linux machines by large.

Himmelblau on the other hand is a piece of middleware that manages the computer through the power cycle system-wide for the whole system, and thus can provide both boot-time initialization (himmelblaud) and reoccuring updates needed to maintain the trust (himmelblaud-tasks), such as Kerberos ticket and that kind of stuff.

a checkpatch error that provides an insecure URL as guidance lol:

WARNING: unnecessary cast may hide bugs, see http://c-faq.com/malloc/mallocnocast.html

Tried to fix it but also https is broken. It's also quite common mistake, meaning that it pushes insecure in volumes to developers.

finnish electro classic from 25-26'ish years ago: https://www.youtube.com/watch?v=xZpZWm5GRXo

i.e. when the electroclash boom was ongoing with lots of stuff coming from i-f, parallax corporation, miss kittin and the hacker, dmx krew and others. stuff like that was playing a lot at venues. good times :-)

for what it is worth this is how you “lsusb” in macOS:

ioreg is a wrapper utility for doing queries from https://developer.apple.com/documentation/iokit

just learned this and now i’ll probably remember it too after writing this ;-)

submitted fish version of the mc-wrapper:

https://github.com/MidnightCommander/mc/pull/4726

i'm actually using zsh (and no immediate plans to switch), but i just wanted to see how fish feels like so did a little bit of scripting ...

Really have been satisfied on moving to Fastmail for personal, kernel.org account etc. It scales the best from iPhone to mutt with no glitches.

Just learned how to update OVMF_VARS.fd offline before running QEMU:

 virt-fw-vars \
    --input "$OUTPUT/OVMF_VARS.fd" \
    --output "$OUTPUT/OVMF_VARS.fd" \
    --append-boot-filepath /EFI/debian/grubx64.efi

E.g., in Debian the package containing virt-fw-vars is python3-virt-firmware but it is also available from PIP: https://pypi.org/project/virt-firmware/

IMHO still the best "top". atop has especially come handy over the years in kernel debugging given the vast amounts of detailed proc data it shows: https://atoptool.nl/
