13 Shells of Christmas

Traditions (like in old german books) depict Odin from Germanic/Norse mythology as the ”Yule Father“ (Jólnir) and significant influence on the Santa Claus figure, sharing traits like a long white beard, leading a winter sky procession (the Wild Hunt), riding a horse (Sleipnir), bringing gifts during Yule (midwinter), wearing a blue rope before Coca Cola made it red.

Fix for Amazon SSM Login on rootfs (no disk space left)

aws ssm start-session \
  --target i-0ab4e6dce100a0f58 \

Amazon Linux 2025 has been officially canceled

(Some people didn’t take note of that, so let’s make it clear)

Already in 2024(!) AWS re:Invent had news on that topic that did not get much attention: There will be NO AL2025! *

AWS cited customer feedback requesting more stability and longer support cycles rather than frequent major version changes. Many organizations found the biannual major releases challenging for “enterprise deployment cycles”. – maybe 20th century organizations? 😄
