eichin··on The coolest use for the Vision Pro
Or to the drug-assisted VR scene in Minority Report. (Though that's even darker...)
eichin··on First Robotic Satellite Servicer Launched
https://www.linkedin.com/feed/update/urn:li:activity:7487913... via https://bsky.app/profile/jfoust.bsky.social/post/3mrqa6o24as... says that they're having attitude control problems including "Currently, the LINK spacecraft has two of three reaction wheels non-functional and partial RCS functionality" but they have already made some attempts to use the thrusters to stabilize it and they seem to be working. The note comes across as "busy but hopeful" (and pleasantly but unusually transparent.)
eichin··on First Robotic Satellite Servicer Launched
They should be close to the end of the checkout stage, then it'll take 4 weeks to get in the right orbit and another 2 weeks of inspection ( https://en.wikipedia.org/wiki/Swift_boost_mission#Boost_oper... has an easier all-in-one-place timeline than the NASA pages.)
eichin··on LLM Usage in Debian: Three Proposals
At least in the US, no, not many, and the fish itself is very import restricted to keep the toxic parts from reaching the market. Hmmm.
eichin··on Why Sony can't bring back its classic Walkman models
it's a little weird but most of the sub $50 ESP-32 boards on waveshare include an MP3 player as one of many demo bits of code (primarily because it shows off code for "read from microSD card" and "drive the DAC".) It's not quite what you're asking for, just a benchmark that it's kind of "too easy to build" which might get in the way of actual products.
eichin··on Astronomers may have found the first exomoon
Monitoring "space weather" (paying attention to the sun/solar flares/CMEs etc) is important to keeping our earth orbiting satellites functioning. (That's without getting into what a modern "carrington event" would look like.)

eichin··on Terrence Tao's ChatGPT Conversation about the Jacobian Conjecture Counterexample
ugh, I had some text book that used R for a scalar value and (edit: \u{MATHEMATICAL BOLD FRAKTUR CAPITAL R} here) for a matrix that was related to the scalar and I had to go back and re-learn a month of material once I figured out that the font was being used with intent
eichin··on 10 REM"_(C2SLFF4
BASIC is older than most people realize, but it's still half a decade younger than Lisp.
eichin··on Cornell's Interactive Wall of Birds
The description of Gallus Gallus ("Red Junglefowl" but also described as the "original chicken") mentions it being an introduced species in Hawaii (but also that it's interbred with "feral and domestic chickens" so it's hard to identify specifically.)
eichin··on I'm Making Strandfall, a Solarpunk Orienteering Larp
Thanks!
eichin··on The Kimi K3 Moment
The only ones getting paid this time around had registered copyrights (in the US at that.)
eichin··on GPT-5.6 used a prompt to close a 30-year gap in convex optimization
what's getting built is more like Asimov's Spacers/Solarians, though. (Vastly reduced population wielding thousands of robots each)
eichin··on Fake food delivery site for the dopamine
and "cookie clicker" is already taken :-)
eichin··on I'm Making Strandfall, a Solarpunk Orienteering Larp
Only vaguely related: is that tiny receipt printer at the end of the article real or is it itself a mockup? (It appears to be smaller than any of the ones I've come across, and google image search was unhelpful.)
eichin··on Sleep regularity is a stronger predictor of mortality risk than sleep duration (2023)
The anecdotes I picked up in my early driving days suggested that red being more visible also meant it was more visible to traffic cops and get more attention - and thus more speeding tickets even for relatively small violations. (No idea if this was supported by insurance data - in the most solid of the anecdotes, the driver in question had just traded in a bright red porsche for something comparably fast but "not red" and didn't have followup numbers yet :-)
eichin··on We don't use AI in any of our design or production processes
The "you'll get left behind" crowd has already made it clear that they're not worth engaging with, you're not going to find reasonable voices anywhere those threads are happening...
eichin··on Female US rower completes historic solo journey from California to Hawaii
I recall one article mentioning that there's desalination gear on board (that's what the solar panel is for?)
eichin··on A Special Wireless-Free Nikon Camera Is Publicly Available for the First Time
I don't use it for my primary workflow, but I use the Android app all the time for "grab a couple of interesting shots to send to friends, from the parking lot right after a hike/nature shoot", and it's fine for that (and for firmware updates.)
eichin··on What to learn to be a graphics programmer
I don't really see this with modern graphics programming, but I was highly amused that my 1980s-1990s graphics skills (in particular, coordinate transform math) were very useful when I started working in robotics in the 2010s-2020s (because forward and inverse kinematics are exactly the same thing as 2d/3d projections.)

The trick there is that they both have related physical analogs, and machine learning math doesn't really (in that while you can visualize them spatially, it doesn't seem to help solve any problems in that space.)

eichin··on I built a mmWave material classification radar (2025)
At least in the US (and this probably is different from Europe) it matters a huge amount how the asbestos is exposed to the environment. Asbestos that's sealed up generally gets (a) labelled so noone cuts into it (b) sealed up even further - but if it's exposed, the evaluation is more about "can it get into the air" (sealing is again the preferred step, epoxy over tile, that sort of thing) - actually removing it is a last resort. So "mere detection" is a really small part of the problem.

(Of course, the place I've dealt with this the most was a former post office building from the late 1930s - we didn't really need tests, a historian would probably have just said "of course you have asbestos" :-) It does expose an interesting problem with the labeling part, though: USPS as an ancient federal agency has its own rules for things and had a distinct asbestos markers - an A in a point-down triangle - which we fortunately found documentation for, it isn't public record.)

eichin··on .self: A new top-level domain designed to support self-hosting
Well, the .meow kickstarter raised €121,896 with just an assertion and a voucher system, so there's at least some community support for this kind of thing, without it needing to be a good idea :-)
eichin··on The Boeing 747 begins its final descent
Higher cabin pressure, but it is marketed in pressure-corresponding-to-altitude; Norwegian Airlines for example keeps their cabins at 6000ft, ie. equivalent atmospheric pressure to being at 6000ft. (Looks like "equivalent effective cabin altitude" or just "cabin altitude" is the more accurate term.) So yeah, I worded that backwards, higher pressure, lower altitude, is more comfortable for passengers (me) especially on longer flights.
eichin··on The Boeing 747 begins its final descent
Concorde is exotic, absolutely, but having seen the one at Udvar-Hazy I'm not sure I'd call it beautiful... not being an aircraft designer, my sense for this is of course biased by the way the average commercial jet looks like, well, a commercial jet, and the Concorde looks like someone who was really good at paper airplanes got ahold of the CAD system for the weekend :-)
eichin··on The Boeing 747 begins its final descent
I had a round trip BOS↔LHR that was 747 eastbound, 777 westbound; I ended up on the upper deck of the 747, which was fascinating as an otherwise casual flyer. One especially memorable bit was landing - you're basically three stories up and suddenly the wheels are on the ground, and you're still three stories up :-)

(I'm still happy to have traded that for planes with a much higher cabin pressure-altitude - and would trade even further for business-class transatlantic non-cruise ships. But it was definitely fun to have had the experience.)

eichin··on Long Wave radio era set to end with switch-off
"valves" being british for vacuum tubes (though there's an entire generation of scifi where future computers are built around miniaturized valves even among american authors for some reason, Asimov in particular)
eichin··on Anonymous GitHub account mass-dropping undisclosed 0-days
In emacs, c-x 8 RET prompts you for unicode character names (or hex) so for rare use you can just spell it out. There's also C-x 8 _ m for em dash and C-x 8 _ n for en dash. (Hit c-x 8 c-h to get a full list of those bindings, like any normal secondary map - they're about as idiosyncratic as the XCompose bindings, but you might find some of them "stick" in your head better (I personally like "C-x 8 1 / 2" better than "Compose 1 2" even if it's a lot more typing...)
eichin··on The Xteink X4 E-Ink Reader
(having it right there mostly serves as a physical token/reminder that I don't want to get sucked in to my social media and other phone apps as much, so if I'm just using it to fill "politely waiting" time I can just grab the x4 instead. I also have a trivial pandoc-generated epub todo list as the first document, though that would work better as a crosspoint fork/feature really...)
eichin··on The Xteink X4 E-Ink Reader
It's way smaller than modern phones, though - I clip mine to the back of my Samsung (magsafe case) and it only blocks one of the five cameras. (phone: 288g xtelink x4: 75g.)

(also: hasn't the x4-v2 already been announced that is supposed to have a frontlight?)

eichin··on In memory of the man who put red and green squiggles under words
> with AI I imagine ...

I think that might be just imagination - android autocorrect in particular got sufficiently worse that I finally turned it off (I still use it as a "typing assist" - it only displays choices that I can tap to replace, or (more often) ignore.)
