Flying to Berlin in near future to meet up friends from Tallinn :-) It's cheaper than train + boat.

literally me

"marvel's mignight suns" is a cool game but why they have to talk so much, and why i need to hang out.

i don't hang out IRL either 🤷

thank you mr showerhead for giving this freedom my US comrades (pun intended).

container hack for build: unshare + chroot. unshare guarantees unmounts, given a ephemeral file system namespace :-)

#!/bin/sh

set -eu

rootfs_dir=$1
adm_user=$2

if [ "$#" -eq 3 ]; then
  proxy_address=""
  cmdline=$3
else
  proxy_address=$3
  cmdline=$4
fi

sudo unshare --mount --pid --fork sh -c "
  mount --bind /sys '$rootfs_dir/sys'
  mount --bind /dev '$rootfs_dir/dev'
  mount -t proc proc '$rootfs_dir/proc'
  mount -t devpts devpts '$rootfs_dir/dev/pts'
  chroot '$rootfs_dir' su - '$adm_user' -c 'export PUAVO_CACHE_PROXY=\"$proxy_address\"; $cmdline'
"

Anyone interested on keyring:

If this would work out then possibly also radiate to /proc/keys.

I.e. it could also similarly "knock for reference" but that is not within scope of this patch.

Happy International Asexuality Day!

My fourth Obnam 3 development session. Put into place the scaffolding to add chunk encryption, but didn't have the time to actually implement the encryption.

Small steps and tea is the way to reach goals while having fun.

(Obnam 3 is my Sunday project to experiment with implementing fundamental components for backup software.)

BREAKING: The C++ committee imposes tariffs on non-US locales.

Telegram asked me pin, which was 26214, which is same as the number of colors on #Amiga 1200 ;-)

That at least what I recall...

Quite cool, I have to say. fwupdmgr managed to update my HP USB-C Dock G5.

recycle is now free, the program to create .rex loops: https://www.reasonstudios.com/recycle

fun Linux fact: because MAP_SHARED|MAP_ANONYMOUS is actually a file-backed mapping under the hood, unmapping part of such a mapping does not discard the data stored in that part:

$ cat mremap.c
#define _GNU_SOURCE
#include <err.h>
#include <stdio.h>
#include <sys/mman.h>
int main(void) {
  char *p = mmap(NULL, 0x2000, PROT_READ|PROT_WRITE, MAP_SHARED|MAP_ANONYMOUS, -1, 0);
  if (p == MAP_FAILED) err(1, "mmap");
  p[0x1000] = 'X';
  if (munmap(p+0x1000, 0x1000)) err(1, "munmap");
  // that 'X' we just wrote... is it gone?
  // nope, let's bring it back!
  p = mremap(p, 0x1000, 0x2000, MREMAP_MAYMOVE);
  if (p == MAP_FAILED) err(1, "mremap");
  printf("p[0x1000]='%c'\n", p[0x1000]);
}
$ gcc -o mremap mremap.c
$ ./mremap
p[0x1000]='X'
$

US government’s attack on free speech, science, and research is causing a brain drain

How do you create a brain drain and lose your status as eminent destination for scientists and researchers?

The United States seems to be sending out questionnaires to researchers at universities and research institutes outside of the United States, asking them about their political leanings. Dutch universities are strongly advising Dutch researches not to respond to the questionnaire

8 Bits High live at a local museum near my home year ago:

Vapriikki (https://www.vapriikki.fi/en/) has e.g.,

1. Most extensive video game museum in Finland.
2. Some other tech stuff like the first ever IRC Server in a glass case ;-)

Great place to visit if around here.

I started to do my second gym program with the move that I hate the most because it is such a struggle: Bulgarian squat.

I guess that means it does something...
