wiredfool··on Early universe's 'little red dots' may be black hole stars
There’s a sculpture in Volunteer park on Capitol Hill in Seattle called the Black Sun, and it’s notable feature after being black is the hole in it.

wiredfool··on Vector Tiles are deployed on OpenStreetMap.org
OSM has always overdone boundaries in my opinion, the raster tiles show national/international waters and electoral districts, which are of limited use for most purposes.
wiredfool··on Vector Tiles are deployed on OpenStreetMap.org
The nice thing is, that's just a style, not a property of the tiles. So if you want to alter the rendering, it's "just" a change to the style of that layer/attribute.
wiredfool··on FOSS4G Europe 2025 live streaming [video]
There's a ton of image recognition AI being used in the geo space, for segmentation and feature identification. It's just not LLMs.
wiredfool··on Pbf2sqlite: Reading OpenStreetMap into a SQLite Database
SQLite + spatial (and specific metadata tables) is essentially the Geopackage format, which can be considered the modern equivalent of a shapefile.

Which is to say, yes, SQLite has geospatial operations and they’re well supported by the open source gis stack.

wiredfool··on They tried Made in the USA – it was too expensive for their customers
Music, movies, microcode and high speed pizza delivery.
wiredfool··on Lateralized sleeping positions in domestic cats
I prefer chirality for cats, they sleep either clockwise, counterclockwise, or possibly corkscrew.
wiredfool··on The AIpocalypse is here for web sites as search referrals plunge
I’d be stunned if my sites have as much as 1% non-bot traffic, even outside of the ones that are vaguely straddling the border between bot and Ddos.
wiredfool··on ELIZA Reanimated: Restoring the Mother of All Chatbots
Once, way back when, I ported eliza to $lang and hooked it up to my AIM account. All well and good till the boss interacted with it for a couple of minutes before twigging on.
wiredfool··on Preparation of a neutral nitrogen allotrope hexanitrogen C2h-N6
That would be this one: https://www.science.org/content/blog-post/things-i-won-t-wor...

> We're talking high-nitrogen compounds here (a specialty of Klapötke's group), and the question is not whether such things are going to be explosive hazards. (That's been settled by their empirical formulas, which generally look like typographical errors). The question is whether you're going to be able to get a long enough look at the material before it realizes its dream of turning into an expanding cloud of hot nitrogen gas.

wiredfool··on US Streetlights Are Turning Purple
I thought it was two - the sodium double emission line.
wiredfool··on How the BIC Cristal ballpoint pen became ubiquitous
I like them. Don't use pens much, used to be a bit picky, either fountain pens or roller balls or gel, but they'd always leak or be dry or not be ready to roll when I needed them.

I had one Cristal pen that I managed to hold on to and use through at least three moves and 8+ years, until I finally ran it out of ink. It didn't get lost, destroyed, eaten (by puppies or humans), or quit working -- until there was nothing left of it. It was a small accomplishment, but one that I'm absurdly proud of.

wiredfool··on I taught my 3-year-old to read like a 9-year-old
(To be clear, child in question is now 20)

The problem was coming up with enough to read that wasn't too scary when he was young. Even the Hobbit was rough. Harry Potter is downright scary. Book series were falling in a week. We never had Christmas present books that lasted till New Year's.

I'm pretty sure that we have The Dark is Rising, but it was never one that was a reread, if they ever got through it. I've read the Little Fuzzy and other H Beam Piper books, and they're a little 50's to really let a young kid loose on.

Terry Pratchett worked, specifically the Bromeliad Trilogy. Eragon was ok. There was a set of Wings of Fire. And bookshelves of others that are gone by now.

wiredfool··on I taught my 3-year-old to read like a 9-year-old
First Child: ooh I know nothing. Nothing works. Second Child: Ok, We've got this. Except, No, completely different. Third Child: At least we've got the range. No. No you don't.

Big issue we had with the first was that he was reading several years above grade level, and we ran out of interesting things for him to read that were age appropriate. When they can read the Hobbit at 7, but are scared, it's really difficult.

Of course, he's now reading things like type theory and scares me with Nix advocacy, so I guess it all comes around.

wiredfool··on Vanguard 50-year anniversary CEO letter
My Grandfather was young during the Great Depression, and his relationship with money was much different than I can imagine. His idea of diversified investments was cash in several different banks. He just didn't spend money if he didn't have to -- to the point of not wanting to get a cordless phone (which could be carried in his walker) because he had a perfectly good wired one in the phone nook.

When he died in his 90s, his car was the one he bought to visit my parents when I was born.

wiredfool··on I use zip bombs to protect my server
Amazon's scraper has been sending multiple requests per second to my servers for 6+ weeks, and every request has been returned 429.

Amazon's scraper doesn't back off. Meta, google, most of the others with identifiable user agents back off, Amazon doesn't.

wiredfool··on How Monty Python and the Holy Grail became a comedy legend
I really don’t think that the blackface in the Philosophers sketch is about the reaction of the triggerable.
wiredfool··on Nvidia adds native Python support to CUDA
Curious what the timing would be if it included the memory transfer time, e.g.

  matricies = [np.random(...) for _ in range]
  time_start = time.time()
  cp_matricies = [cp.array(m) for m in matrices]
  add_(cp_matricies)
  sync
  time_end = time.time()
wiredfool··on Things I Won't Work With: Dioxygen Difluoride (2010)
And the bit about using dimethyl mercury as a monopropellant.
wiredfool··on Things I Won't Work With: Dioxygen Difluoride (2010)
There's also adding a bit of Flourine to one of the Fuming Nitric Acids to make it easier to handle, because of the flouridation of the surface of the tanks.
wiredfool··on Things I Won't Work With: Dioxygen Difluoride (2010)
Absolute classic of the genera

  At seven hundred freaking degrees, fluorine starts to dissociate into monoatomic radicals, thereby losing its gentle and forgiving nature.

  If the paper weren't laid out in complete grammatical sentences and published in JACS, you'd swear it was the work of a violent lunatic.
wiredfool··on All clothing is handmade (2022)
I bought a Saddleback wallet at least 14 years ago, and it's still in pretty good shape. There are a couple of stitches that have broken on the fold, but it's generally ok. Has a nice patina.

Though, it's thick. Really thick. And the card pocket edges are thick enough that they will destroy a credit card in 3 years or so. (Except for the top one on each side, and the hidden slot behind the visible cards.)

I was expecting to use it forever, but between the thickness and just not using nearly as many cards/cash any more, I'll probably give up on it and make a thinner one that's specific to the 3 or 4 cards I use and a stashed bill or two.

(Make because we now have way too much leather because my wife has started making barefoot shoes, and hey stash. Have a really nice leather laptop sleeve now too.)

wiredfool··on Calibre 8.0
Some ebooks that have extremely long chapters have very slow page turning performance towards the end of the chapter. (e.g. most of the Terry Pratchett Discworlds that are essentially one large chapter)

There's probably an O(n^2) page break algo there which is fixed with the kepub format

wiredfool··on FOSS infrastructure is under attack by AI companies
Across my sites -- mostly open data sites -- the top 10 referrers are all bots. That doesn't include the long tail of randomized user agents that we get from the Alibaba netblocks.

At this point, I think we're well under 1% actual users on a good day.

Harfbuzz is designed to run on top of the FreeType Renderer. https://harfbuzz.github.io/what-does-harfbuzz-do.html
wiredfool··on Apple M4 MacBook Air review: I have no notes
Huh. Definitely wider than the M2.
wiredfool··on Apple M4 MacBook Air review: I have no notes
Might be a difference, with the M4 marginally crisper, or a bit more haptic feedback. Or it might be that my M2 is on a stand and the M4 is on the desk.

Also, the screen is totally clean. No dust or smudges.

wiredfool··on Apple M4 MacBook Air review: I have no notes
Mine came yesterday. It's nice enough, and exactly what one would expect from a minor speed bump. Doesn't feel any different than my work M2 Air, though it's faster? It feels a bit snappier than the M1 Air it replaced, and for the same spec it's cheaper these 3+ years later.

The subtle blue is nice, it's like a colder sliver look than what it was. I'd still like one in the blue that the series 6 watches came in.

I wouldn't have upgraded, except that I'm in need of a hand-me-down for a kid's laptop.

Oddly, using Migration assistant -- display and internal/external keyboard settings didn't transfer over, but Apple Intelligence remained off. Chrome reset it's search engine.

wiredfool··on Make Ubuntu packages 90% faster by rebuilding them
Yeah, any of GeoPackage (sqllite db with spatial extensions), FlatGeoBuf, or GeoArrow/GeoParquet would be far better for querying.
wiredfool··on What We've Learned from 150 Years of Stock Market Crashes
I made sure I had Smoot Hawley on my bingo card for this year.
