125. Open-Weight Models Are Getting Serious: GLM 4.7 vs. MiniMax M2.1
Two new open-weight models dropped in December, claiming strong agentic coding capabilities: GLM 4.7 from z.AI and MiniMax M2.1. We ran both through a multi-phase coding test in Kilo Code to see how they handle real implementation work.

Precision diarization, real-time transcription, and a new audio playground.
127. How to carry more than your own bodyweight (2025)
Some communities have developed techniques to help them carry heavier loads. Here's what we can learn from them.
128. Pentagon cutting ties w/ "woke" Harvard, ending military training & fellowships
The Pentagon says it will cut ties with Harvard University, ending graduate-level military training, fellowship and certificate programs.
129. Data centers in space makes no sense
SpaceX acquired xAI on Monday, forming a $1.25 trillion behemoth with the goal of sending data centers into space. They’re not alone either: Google and a host of startups like Lonestar, Axiom, and Nvidia-backed Starcloud are scrambling into the field. Endless solar power, free real estate, and most importantly, huge rockets! What more could you want?
130. Google Translate apparently vulnerable to prompt injection
tl;dr Argumate on Tumblr found you can sometimes access the base model behind Google Translate via prompt injection. The result replicates for me, an…

132. Solving Shrinkwrap: New Experimental Technique
In this article, I present my new technique for solving a CSS problem that was deemed impossible — true shrinkwrapping of an element with auto-wrapped content. By using anchor positioning and scroll-driven animations, we can adjust our element’s outer dimensions by measuring its inner contents, demonstrating that for many cases this can already work and might unlock a future native feature.

143. Making Ferrite Core Inductors at Home
I have recently been working on tuning circuits, which typically consist of an inductor and a capacitor (i.e. an LC circuit). For those not familiar with inductors, they are passive components that store energy in a magnetic field. They oppose changes in current, meaning that they pass direct current (DC) and block alternating current (AC). While there are many types of inductors, ferrite core inductors are useful because the high magnetic permeability of ferrite leads to a significant increase in induction.
