Raspberry Pi als Tor Relay

Hinweise zur Installation von Tor auf einem Raspberry Pi.

  • Raspberry Pi OS via Raspberry Pi Imager auf die micro SD Karte schreiben (SSH aktivieren!)
  • Ethernetverbindung und Stromversorgung herstellen
  • Via SSH einloggen
  • Pakete aktualisieren:
    apt-get install update
    apt-get install upgrade
  • Tor installieren
    apt-get install tor
  • /etc/tor/torrc:

SocksPort 0
Log notice file /var/log/tor/notices.log
RunAsDaemon 1
DataDirectory /var/lib/tor
ORPort 9001 IPv4Only
ExitPolicy reject *:*

  • Auf dem Router Port 9001 öffnen
  • systemctl restart tor@default.service
  • Auf einem schwachbrüstiger Raspberry Pi kann tor von systemd beendet werden, weil tor nicht innerhalb von 5min einen erfolgreichen Start signalisierte (zu erkennen in den Logs, wenn inmitten des Bootstrapping das Programm neu gestartet wird). Lösung: Erhöhung der TimeoutStartSec (z.B. von 300 auf 600) in /lib/systemd/system/tor@default.service.

We’ll see

A farmer had only one horse. One day, his horse ran away.

His neighbors said, “I’m so sorry. This is such bad news. You must be so upset.”

The man just said, “We’ll see.”

A few days later, his horse came back with twenty wild horses following. The man and his son corralled all twenty-one horses.

His neighbors said, “Congratulations! This is such good news. You must be so happy!”

The man just said, “We’ll see.”

One of the wild horses kicked the man’s only son, breaking both his legs.

His neighbors said, “I’m so sorry. This is such bad news. You must be so upset.”

The man just said, “We’ll see.”

The country went to war, and every able-bodied young man was drafted to fight. The war was terrible and killed every young man, but the farmer’s son was spared, since his broken legs prevented him from being drafted.

His neighbors said, “Congratulations! This is such good news. You must be so happy!”

The man just said, “We’ll see.”

Unix Pipes

Doug McIlroy beschreibt Pipes, lange bevor Unix das Licht der Welt erblickte.

            Summary--what's most important.
    To put my strongest concerns into a nutshell:
1. We should have some ways of coupling programs like
garden hose--screw in another segment when it becomes when
it becomes necessary to massage data in another way.
This is the way of IO also.
2. Our loader should be able to do link-loading and
controlled establishment.
3. Our library filing scheme should allow for rather
general indexing, responsibility, generations, data path
4. It should be possible to get private system components
(all routines are system components) for buggering around with.

Arrivederci, capitano!

Nächstes Jahr werde ich nicht mehr dabei sein, ich mache Platz für die jungen Spieler. Am Montag werde ich mich von meinem Stadion verabschieden und in Florenz wird mein letztes Spiel sein. Ich verabschiede mich mit Freude von dieser Mannschaft, von der ich immer der grösste Fan sein werde, denn Juve bleibt bei dir.

18 Jahre. Es war eine Ehre.

World Nature Photography Awards 2022

Amos Nachoum, USA – Gold winner and grand prize of world nature photographer of the year

For hours, I waited for the low tide to arrive along a shallow lagoon on a remote island off the Antarctic Peninsula. Like clockwork, the leopard seal arrived in the lagoon just before low tide. It put its head in the water and looked just like a rock sitting in the receding water. The young Gentoo penguins only dare to enter the water when it is shallow and when they got close enough to the seal, it turned its head at lightning speed, catching one of the penguins by its feet and taking it to deep water. Once the seal reached open water, I followed it and swam parallel to it, observing its actions. To my surprise, it let go of the penguin twice. Each time, the seal chased after the penguin again, as if it was enjoying the game. The terrified penguin tried to escape as the game continued. But soon, the end came.


Jetzt hat es mich doch noch erwischt.

Am selben Tag, an dem Go 1.18 veröffentlicht wurde, färbten sich die C- und T-Linien rot.

Milde Symptome (3 x 💉; yeah science!), danke der Nachfrage.
