Wie wahrscheinlich ist der nächste Buchstabe?

Zwei kleine Programme, jede Menge Buchstaben und die Frage, wie aus Zufall plötzlich etwas entsteht, das wie Sprache aussieht.

Was passiert eigentlich, wenn ein Computer einen Text schreibt? Woher weiß er, welcher Buchstabe als Nächstes kommen soll? Und wie viel Statistik braucht man, damit aus einer scheinbar zufälligen Folge von Zeichen etwas halbwegs Lesbares entsteht?

A log store with a search box is a library without a catalogue. So Graylog got one: two dashboards as code, for the morning round and the slow-website afternoon.

First catch: fail2ban was watching every attack and banning nobody. It couldn’t read its own logs.

Part 3 of my Proxmox HA lab, with LibreNMS, CSP reports, WordPress updates and a DSGVO appendix. PDF inside.

Already counted in the numbers above.

My Proxmox lab’s logs were well kept and never read. Now Graylog reads them: three Data Nodes that never move, one server that moves when it has to, and every remote address in one field, so one search follows one visitor everywhere.

Seven failure tests found a firewall that had never been on. A Data Node rebuild went from 39 minutes to 9.

Write-up and a 70-page PDF:
