they are attempting to add more ram to a system. the old chips were removed, and they've connected wires to an external set of chips. ram is fast. really fast. the electrical signal travel times are measures in nanonseconds. 1ns can generally travel 6-9 inches on copper. ram needs the signals to arrive very near the same time, consistently, across every parallel wire. pcbs go to great lengths to make sure this happens. handcut and handsoldered wires dont have the same precision. so this person made the timing less precise by doing this, and they also added actual travel distance, which makes the error margins much smaller. it's unlikely to work, but it's possible. then there's the sheer persistence of this; they had to cut and solder every piece of wire here. ddr5 is 288 pins, so that's 288 individual wires they cut and soldered on both ends. impressive effort.

just wrote code for my agents to talk to each other. This was the test the coding agent wrote. fucking scariest thing I've seen in a year and a half of ai-assisted coding.

keystone essential internals. I was too lazy to dig out my heat gun and in this case, that was a terrible mistake. don't know if I will post a video. it's a bit of a disaster. have some pictures
