Magma: A foundation model for multimodal AI agents (microsoft.github.io)
Magma is the first foundation model that is capable of interpreting and grounding multimodal inputs within its environment. Given a described goal, Magma is able to formulate plans and execute actions to achieve it. By effectively transferring knowledge from freely available visual and language data, Magma bridges verbal, spatial and temporal intelligence to navigate complex tasks and settings.

1972 Unix V2 "Beta" Resurrected (tuhs.org)
Hi everyone, First-time poster here. Near the end of last year, I did some forensic analysis on the DMR tapes (https://www.tuhs.org/Archive/Applications/Dennis_Tapes) and had some fun playing around with them. Warren forwarded a few of my emails to this list at the end of last year and the beginning of this year, but it was never my intention for him to be my messenger, so I'm posting here myself now.

The 8-Bit Era's Weird Uncle: The TI-99/4A (wordpress.com)
It’s been awhile since I’ve looked at an architecture that’s completely new to me, and I haven’t done any since creating my new scheme for dedicated platform guides. I’ve now gotten enough material together that I can kick off an exploration of a new platform for me: the Texas Instruments TI-99/4A. For this new introduction, I’ll be splitting it into three parts, two of which go live today:

F8 – an 8 bit architecture designed for C and memory efficiency [video] (fosdem.org)
Even in modern devices, 8-bit processors are found, but the architectures used are often not well-suited to programming in high-level languages, such as C. E.g. MCS-51 (8051, 8052) based microcontrollers in the Realtek WiFi chipsets. The f8 is an architecture based on the experience and lessons learned from maintaining Small Device C Compiler (SDCC) and the many 8-bit architectures it supports.

DOGE has 'god mode' access to government data (theatlantic.com)
DOGE has achieved “God mode.” That’s according to an employee in senior leadership at USAID, who told us that Elon Musk’s Department of Government Efficiency now has full, unrestricted access to the agency’s digital infrastructure—including total control over systems that Americans working in conflict zones rely on, the ability to see and manipulate financial systems that have historically awarded tens of billions of dollars, and perhaps much more.

Agent-Less System Monitoring with Elixir Broadway (opsmaru.com)
We've started working on something that will be a critical component the Opsmaru platform. This part requires having proper infrastructure monitoring for several reasons. While Opsmaru has health monitoring for every cluster managed by the platform, it doesn't give us deep insights into the metrics of the systems.

Broken legs and ankles heal better if you walk on them within weeks (scientificamerican.com)
Twenty years ago my husband, Mark, broke his left ankle and was in a cast and on crutches for nearly two months. Last year he broke the other ankle. But this time, after surgery, his doctor surprised us by instructing Mark to walk on it two weeks later.
