I'm not the only one who gets kept awake at night about this, right? https://en.wikipedia.org/wiki/Carbon_dioxide_in_the_atmosphere_of_Earth#/media/File:Mauna_Loa_CO2_monthly_mean_concentration.svg Not the graph itself—it's horrifying—but the misinterpretation of how urgent it is. At 500ppm, CO2 begins to have measurable impact on human cognition. We're almost there. But it also means there's *no margin any more*. Any closed room now quickly results in CO2 issues in humans. It...

Holy crap I actually finished PCB layout and all the checklist. New phase: finding alternates for all the "Basic" parts JLCPCB has either replaced or stopped being "Basic" since the last time I checked.

Oh grumble, so Linus Torvalds is pro-LLM then? I could draw a straight line from "NVidia binary blob module does not violate GPL" (2000s) to "LLMs are ok" but I'd come across as a very cranky old man.

Will always remember Lindsey Graham mostly for his spitting, foaming defense of Brett Kavanaugh, because Kavanaugh got accused of being a predator.

I was this >< close to buying a Framework laptop last year, until I found out their shtick is just social-justice-washing. They're still funding fascists, and still not doing any kind of backpedaling or restorative action. Heck, I even picked up a business card at one point, thinking that might be an interesting place to work... Personally, I've decided this is actively worse than, say, buying a laptop from Apple, Dell or Lenovo; because at least they're not pretending to be s...

Managed to cram the radio board into 1x2&quot; with every pin routed to a header or test point, in just 2 layers. One more thing I don&#39;t need from adafruit. Now I just need to figure out the zone fills, and the silly RF trace impedance.

The bothersome thing about the Cesar Chavez erasure is not that he got erased (well-deserved), but that everyone who was so very angry has now packed up and gone home, probably via a bunch of streets named after similarly awful, but white, people.

Home Assistant deprecating all installation methods except, essentially, &quot;entire (virtual) machine&quot; is not a good sign for the project&#39;s health. In general, it means you&#39;re about to lose the ability to bootstrap, and inevitably lose the ability to reuse any part of it, piecemeal.

I have very, very carefully resized, *LIVE*, the crypt (luks), LVM, and partition tables on my home server-in-a-cupboard. Which means either all went well, and I can finally fix a nearly decade-old issue with the boot partition size. Or... when I reboot it, I&#39;m going to spend most of a day making it bootable again, and/or recover whatever I corrupted. My wife, the voice of reason, has suggested I may want to wait until the morning before I type in the reboot command.

Trying to stick Home Assistant OS in a simple Xen HVM, and it instantly reboots the moment it gets to linux kernel. Like, early enough that it doesn&#39;t even emit any debug on max debug settings. What the actual. This is why I *hate* projects which turn into giant fucking monoliths, especially when the monolith unit is a whole machine image.

The thing that really gets me about how all these LLM prompts are written, especially Claude, is that they&#39;re *IN ENGLISH*. You would think that they might be expressed more precisely and effectively as something in a vector space, native to the model. Nope. Just in English, instructing a mindless, unintelligent algorithm to *hopefully* emit a different token sequence. None of this shit is coding. It&#39;s not anything. This is the upside-down hellscape inverse of coding.

There is absolutely no reason, in any of the incarnations of age/person identification laws, for system services to get involved. There are no strong or specific requirements on vendors. This is *corporations* pushing their internal requirements to open, public repositories, and I suspect always because there’s a promotion involved to the authors.

Like Republican administration, I also have the superpower of traveling in time and space. Sadly I can only travel in time forwards at a constant rate, and in space to immediately continuous space adjacent to me at normal speeds.

All complex, large scale, system (software and hardware) design problems are _also_ a social (governance!) problem: * Conway&#39;s Law: software resembles the organization which put it together. but also... * Reverse Conway&#39;s Law: the organization ends up resembling the way the software was put together. If you&#39;re a &quot;senior&quot; engineer and you don&#39;t get this, you&#39;re still doing it, just by accident. But there&#39;s also people who _know_...

I guess (marketing term) &quot;AI&quot; in the Linux kernel is a self-limiting disease, because at some point Clod will simply delete the repository, or create a branch of the first ever commit with a one line comment, and rebase the entire history.

Oh look the &quot;AI&quot; boosters are all out in force trying to tell us that LLMs are energy efficient, really, when you look in the context of the entire world&#39;s energy usage. (While simultaneously being weirdly proud of how they&#39;re having to significantly increase energy production for entire nations, turn back on nuclear power stations, and build gas turbines because they need more)

Occasionally slip a search into Google, and check how things are going in AI-is-going-great land. I see that numbers, counting, and comparison are still beyond an LLM&#39;s capabilities: &quot;Avoid Sub-millimeter Vias: Use standard via sizes. While they can do smaller, a 0.2mm hole with a 0.35mm–0.4mm diameter is safer.&quot; Uh huh. &quot;Avoid Sub-5mil Traces: Standardize your traces to 4mil or greater. Thinner traces are more fragile.&quot; You keep using that word &a...
