  • Watching people repair old electronics on Youtube has opened my eyes to the realities of real-world electrical engineering. In short: it’s all about tolerances.

    A power supply may have a nominal voltage of 5V, but anything from 4.8 to 5.2 is a-okay. Why? Because your TTL components downstream of that can tolerate that. Components that do 5V logic can define logic zero as anything between 0 and 0.8 volts, and logic one as low as 2 volts. That’s important since the whole voltage rail can fluctuate a lot when devices use more power, or draw power simultaneously. While you can slap capacitors all over the place to smooth that out, there’s still peaks and dips over time.

    Meanwhile, some assembly lines have figured out how to aggressively cost-reduce goods by removing whole components from some circuits. Just watch some Big Clive videos. Here, the tendency is to lean heavily into those tolerances and just run parts hot, under/over powered, or just completely outside the published spec because the real-deal can take it (for a while). After all, everything is a resistor if you give it enough voltage, an inductor if the wire’s long enough, a capacitor if the board layout is a mess, and a heatsink if it’s touching the case.


  • As far as labors of love go, Stardew Valley is probably the most current example. People paid for this thing years ago, but Concerned Ape keeps adding new features anyway. The retro graphics give this thing a timeless quality out of the box, so it already looks “dated” - this hasn’t stopped the robust player community around it. We’ll probably see this game stay relevant for a long time.




  • Renfield.

    I know it’s violent, campy, and corny, but it’s a damn good lesson in what Narcissistic Personality Disorder is and what it does to people. It helped me frame my own abuse and trauma at the hands of abuser’s NPD, in ways that helped me break free from those people later on. Moreover, once you’ve been victimized this way, one has a tendency to fall back into bad habits with abusers. The film just gave me something profound to recall when exercising mindfulness around this cycle, and how to exit quickly.




  • I, for one, want to believe that there are people responsible for this parade that deliberately pulled punches so we don’t go down that path. What was on display was more akin to a living history exhibit, like the Smithsonian itself hired a bunch of costumed actors for the day. If we consider for a moment what an “American-style” propagandized display of full-on military might would actually look like, I am very relieved that the events of the 14th were very, very far removed from all that.







  • This describes how most people have it deployed, yes.

    It gets real fun when you have custom Java plugins, Groovy script, BASH script, Windows runners, and Linux runners, all in play at the same time. Much of which is held together with hopes, dreams, and unicorn farts, willed into existence by wizards that haven’t worked there in over seven years. If upper management could even comprehend the level of deferred maintenance and haphazard software hackery that birthed this electronic Gordian knot, this unholy union of decrepit software and company policy, they wouldn’t sleep. Ever.







  • It’s outstanding at bridging the gap between “I need to mash these two concepts/technologies together” and “the answer is spread across six different StackOverflow threads.” Hunting that stuff down using Google has been a delicate operation even at the best of times in the last 25 years, but it always took a lot of time. With an LLM and each such query, I’ve saved hours, maybe even whole workdays. Fact-checking an AI takes far less effort.
