Spent way too much time chasing some confusing segfaults before realizing that I was 4-byte offsetting and aligning my stack pointer out of habit.

* MENOG 25 region advancement report

Well this is interesting.
I've successfully determined which core is active. Core 1 correctly takes the branch, loads a valid initial stack pointer, and jumps into the infinite loop I wanted it to.
Core 0, on the other hand, crashes when doing basically the same instructions. Weird.

Hey #digipres folks, over on the #ApplesauceFDC discord, someone's been working through how to archive punch cards (since they've got a large stack of them), and put together a documented #format

The Input Stack on Linux
Let's explore and deobfuscate the input stack on Linux. Our aim is to understand its components and what each does. Input handling can be divided into two parts, separated by a common layer. We’ll try to make sense of all this, one thing at a time, with a logical and coherent approach.

»In the old days, technical writers produced documentation in near isolation, surrounded by complex and similarly isolated corporate cultures. From an anthropological perspective, old manuals are like tribal artefacts. The resulting docs show surprisingly rich design and content patterns, more refreshing than we’re used to in the age of googling for Stack Exchange questions and of bowing to Stripe docs.«

'Don't even consider' Microsoft?
To digital natives, Microsoft's IT stack makes Google's look like a model of sanity. A millennial does battle with Redmond's enterprise tools and comes away reeling.

"This series is the result of careful analysis of UDP stack, to optimize the receive side, especially when under one or several UDP sockets are receiving a DDOS attack.
"I have measured a 47 % increase of throughput when using IPv6 UDP packets with 120 bytes of payload, under DDOS."
