Welp, another day another train adventure. This time the train from Zurich left on time, but a mechanical issue resulted in a need to swap trains along the way, making us 40 min late to Munich. Our connection was on the literal other side of the station. We made it with 1 min to spare….

Just a little snow in Zurich today.

Train schedule is a hot mess, but on the plus side it’s snowing here. Anyway on step one of three now, only an hour late.

The more that I look at real plate armor the more I wonder at where our games went wrong.

Snow outside of Munich is beautiful. Quite a difference from the warm temperatures at home.

Annual reminder that the world didn't crash on Y2K because countless people put in countless hours of work to ensure computer systems were updated to handle the date switch from 1999 to 2000.

It was a real problem that a huge group effort fixed.

Every time I hear I'll be home for Christmas play my brain autocompletes the the line 'Christmas Eve will find me' ... with 'and in the darkness bind me.' 🙃

Painful stings like the velvet ants' venom actually evolved to defend them from insect predators, so it's surprising how well they target mammalian nociception ('pain-sensing') pathways.

There's a nice paper on this where they found velvet ant venom caused aversion in fruit flies, mice, and mantis.
Arizona velvet ants are colorful little insects that will DESTROY you. Their sting is described as 'hot oil from the deep fryer'. As wingless wasps, they will drop you to your knees. They will make you call to god. They are the reason countless children are afraid of cute insects.

they are perfect

It's Patch Tuesday and ASP.NET Core has a doozy, with a CVSS score of 9.9, our highest ever. Let's examine why.

The bug enables http request smuggling, which on its own for ASP.NET Core would be nowhere near that high, but that's not how we rate things...
