Soo yesterday I learned that recvfrom on a UDP socket will just silently drop bytes on the floor if your buffer isn't big enough. (modulo the MSG_PEEK flag). Cool.

Certainly makes it easier to implement 😈

Sooo it turns out that my MB runs its pci-e x1 slots in x4 and that my new wifi card doesn‘t like that. Only took me 2h to find out and find the random setting somewhere in the bios.
But it works now!🌈

https://decentraleyes.org/ seems pretty cool

At least RTFM if you _need_ to consume something.

I've been passively looking for decent routing alternatives to google maps for a while, and just stumbled over https://maps.openrouteservice.org/

Looks fantastic, bicycle routing of my everyday routes was spot on!

The only good thing about quarantine is that I‘m somehow managing to catch up with critical role.

Interestingly enough, gunicorn dies due to a SIGSEGV

```
select(8, [7], [], [], {tv_sec=1, tv_usec=0}) = 0 (Timeout)
fstat(10, {st_mode=S_IFREG|000, st_size=0, ...}) = 0
fstat(12, {st_mode=S_IFREG|001, st_size=0, ...}) = 0
fstat(13, {st_mode=S_IFREG|001, st_size=0, ...}) = 0
fstat(11, {st_mode=S_IFREG|000, st_size=0, ...}) = 0
select(8, [7], [], [], {tv_sec=1, tv_usec=0} <unfinished ...>) = ?
+++ killed by SIGSEGV (core dumped) +++
```

Nn to reproducing that with gdb attached.

The postgreSQL DB doesn't initiate the connection dropping, but logs that the client reset its connection. I've followed the recommendation of gunicorn to make /tmp a tmpfs as per http://docs.gunicorn.org/en/latest/faq.html#how-do-i-avoid-gunicorn-excessively-blocking-in-os-fchmod. I guess the next step is trying to run gunicorn with strace and figure out which syscall fails, and why. Oh happy days.

I have a gunicorn master process which exits with exit code 11. It doesn't spit out any logs before dying (on loglevel debug), nor can I find any correlation between the dying and anything I do. Sometimes it happens quickly after startup, sometimes it works just fine for several hours. This happens in a local development environment based on docker, as well as in a production deployment with kubernetes and <insert other container runtime here>.
