day 3 of trying to build llvm.
the build finished, but clang-22 is 5.1GB and it runs out of disk space (with ~25GB free) trying to install. so i guess doing a RelWithDebInfo build was a bad idea. time to delete the build directory and start over again...

TIL: the FreeBSD pkg(8) was written by @_bapt_.
the original plan was to call it "bapt-get".

so FreeBSD is discussing how to replace Cirrus CI, and the suggestions are: 1) a cloud-hosted service, 2) another cloud-hosted service, 3) a third cloud-hosted service.
not one suggestion to just run it ourselves.
sadly, one side-effect of FreeBSD having so much corporate development sponsorship is most of the project is completely industry-brained.

bad news for France, but Linux isn’t free software. it’s controlled by a single dictator, market forces mean you can’t meaningfully fork it, and the direction of development is entirely controlled by the US tech companies you’re trying to avoid.
meanwhile BSD has multiple forks and many downstream distributions. but most people don’t want to use a Unix desktop, they want something like KDE or GNOME. in which case you may as well use Linux and just accept you have no control over your software…

@dch yeah, i have 3 amd64 VMs for 16, 15, and 14, and another six for ports (main and quarterly for each version), and now i need to set up a bunch more for ppc testing, so force pushes are quite annoying :-)
(and my desktop runs Linux, so i can't easily test the build there as cross-build appears to be broken right now - that's on my todo list...)

@js thanks. i do already do all my work on branches, i just don't push them to git.example.org, so i guess i simply need to shift the pull/rebase step to my desktop instead of doing it on dev.

@js thanks! i believe i'm familiar with all of those basic concepts -- i do a lot of manual rebasing for various reasons
by feature branches, do you mean i'd push the dev changes to a new branch on git.example.org, then do the pull/rebase on my desktop before pushing back to main? (so, never push to main from dev.)

so, trying to understand #git...
let's say i have an internal ForgeJo instance at git.example.org. i pull src.git from git.freebsd.org and push it to git.example.org, and now i can pull it on all my dev VMs.
now i want to commit a change, but i don't want to give my dev VM access to my FreeBSD SSH key. so, i make the change on dev, test and commit it, then push it to git.example.org.
then, on my desktop, i pull from git.example.org and push to gitrepo.freebsd.org. but, in the mean time, someone has has pushed another commit to gitrepo.freebsd.org, so i have to rebase and push again.
now i can't push my rebased local branch back to git.freebsd.org without doing a force push, which will break all my clones.
what's the right way to do this?

what type of Grafana graph would you use to visualise CPU usage on a system with 176 CPU threads? i usually like heatmap, but i don't think that's going to work unlses the graph is three miles tall.

> Bluesky users are mastering the fine art of blaming everything on “vibe coding”
https://arstechnica.com/ai/2026/04/bluesky-users-are-mastering-the-fine-art-of-blaming-everything-on-vibe-coding/
it’s easy (and satisfying) to blame this sort of thing on ignorant social media users who are incapable of applying any sort of critical thinking, but this feels like it’s falling into the same old trap of trying to change other people’s behaviour, which is just not practical on a large scale.
i’m going to file this as more evidence that humans are simply not capable of existing in a functional way in social groups of more than a hundred or so.
the Internet was a mistake. we simply aren’t adapted to make the effects of instant worldwide communication networks a positive rather than a negative.

@adrian_blx thanks, but, i'd rather not do that since there's no need for namespaces here: wg only uses IPv4 and the network connectivity is only IPv6 (over wg). so i'd rather work out why wg-quick is breaking it.

latest weird problem: on FreeBSD/ppc64, running as a KVM guest on Linux, 'tcpdump -ni vtnet0' doesn't show any packets.
the network is working fine, the packets just don't appear in tcpdump.
how strange.

@lucasmz although, perhaps this is related to the host itself having a ULA, so it prefers the IPv4 address. but this doesn't seem to be configurable in musl :-/
on FreeBSD it just works, since it realises the host has no IPv4 connectivity.

@lucasmz "why is IPv4 being preferred?" is exactly what i'm asking :D
i do use ULAs internally, but that shouldn't affect "ping bbc.co.uk" since it has a GUA.

but there's no route, so this shouldn't be happening. perhaps wg-quick is doing some "helpful magic" here?

how do i convince Alpine Linux that it doesn't have IPv4 connectivity? when i run e.g. "ping bbc.co.uk", it picks the IPv4 address first, even though it doesn't have a default route.
i can't disable IPv4 because i need it for Wireguard.
i can't use /etc/gai.conf because musl libc doesn't support that.
this makes e.g. apk very slow because it waits for IPv4 to time out before it tries IPv6. i don't understand why it doesn't immediately get "no route to host" over IPv4...
any ideas?
#ipv6 #alpinelinux
