thechao··on Is America's jobs market nearing a cliff?
Two things: (1) Trump doesn't control the prime lending rate (and that's not the interest rate, either); and, (2) he's rapidly headed to lame duck status, already.
thechao··on The VanDersarl Blériot: a 1911 airplane homebuilt by teenage brothers (2017)
My greatgrandmother (born in 1891) left grade school in 6th grade for similar reasons. The real reason she was taken out was "money". (This was rural Indiana about 1903.) She finished her own education through what you might call a master's program by studying her brothers' texts. It was an unwise person who assume her lack of formal education meant anything about her intelligence or informal education.
thechao··on Solving the Whole Year Puzzle with Z3
I think the major issue I have with Z3 is that if your input constraints are large and non-decomposable, then the resulting output is functionally undebuggable. There's a bit of handwaving from Z3folk about using assert_and_track() along with pseudoboolean proxies. But, there's a lot of pitfalls using these techniques. Combining bitvectors and pseudobooleans (y'know — the common case) under implication can either weaken or strengthen the constraints which literally changes the behavior of the given constraint problem. That means that any attempt to add tracing to the problem to debug your constraints can lead Z3 to change its behavior (because the underlying problem is different).

I really like Z3, and I like the convenience of Z3, but ... dang ... it'd be nice if you could trace internal statements.

Oh! Another pet-peeve is that there's no (sane) way to print large expressions. Once an expression gets large, Z3 begins dumping opaque internal variables (K!##). There is no way to get Z3 to unmunge these variables — that information is forever lost to you.

thechao··on 210 IQ Is Not Enough
There's always someone else just as smart, willing to work harder. On the other hand, there's an inexhaustible amount of work & new ideas to work on. If you don't want to do new things, most "old ideas" have been poorly executed: go redo them well.
thechao··on Basalt Woven Textile
Jeans never tear in the crotch; they just upgrade to awkwardly constructed kilts.
thechao··on Why effort scales superlinearly with the perceived quality of creative work
I had a cabinet built and the guy doing the work pointed out that the human eye is really great at detecting line-line deviation; but, building to & correcting for that deviation requires working across the whole surface. He was making an area-effort to linear-quality argument. He said every time you halved the gap, it quadrupled the effort. Also, he said that was what saw-dust & glue were for.
thechao··on I Want You to Understand Chicago
Bivens act, not case. The act modifies the statutes. It's been read but not voted on.

thechao··on I Want You to Understand Chicago
A large part of this lawlessness is rooted in nonnormative behavior. But! there are basic protections we could have right now if we demanded them. First and foremost: the Bivens Act; specifically, the right to bring suit in State court against Federal agents. Presidential pardons can't help these thugs in State persons.
thechao··on Transparent computer monitor designed to protect your vision
Why does it need to be novel? It's (in theory!) a product you can buy. There's a bunch of different car companies & phone companies & writers & stuff, right?
thechao··on The trust collapse: Infinite AI content is awful
There's always someone willing to outthink you. That's the whole premise of a magic show: there are people willing to dedicate irrational amounts of time to trick you in to believing something that isn't true.
thechao··on US startup Substrate announces chipmaking tool that it says will rival ASML
Asking for a dollar is going to land you in jail. You need to ask for a billion dollars.
thechao··on The Case That A.I. Is Thinking
I'm not really onboard with the whole LLM's-are-conscious thing. OTOH, I am totally onboard with the whole "homo sapiens exterminated every other intelligent hominid and maybe — just maybe — we're not very nice to other intelligences". So, I try not to let my inborn genetic predisposition to exterminate other intelligence pseudo-hominids color my opinions too much.
thechao··on Learning to read Arthur Whitney's C to become smart (2024)
Every time I read about APL, I'm reminded of Lev Grossman's "The Magicians" — I'm always imagining some keyboard with just a little bit more than two dimensions; and, with sufficient capabilities, I could stretch to hit the meta-keys that let me type APL directly on my modified split MTGAP keyboard.
thechao··on Data centers contribute to high prices as energy bills electrify local politics
Which is why cheap batteries will be the camel that broke the straw's back. It's really hard to find numbers, but I like 20–30$/kwh by 2030. At those prices I can get a 4 day backup for an oversized (50kw) solar panel install for my house for 20k$. Why even hook up to the grid, at all?
thechao··on Trump directs nuclear weapons testing to resume for first time in over 30 years
Voting.
thechao··on Why formalize mathematics – more than catching errors
Terence Tao posts on mathstodon fairly regularly about lean, AI, and math. I'm not going to interpret his posts.
thechao··on US probes Waymo robotaxis over school bus safety
They drive on highways here, in Austin, all the time. They do just fine. My kids love to wave to Waymo.
thechao··on Greg Newby, CEO of Project Gutenberg Literary Archive Foundation, has died
I'm at high risk for colon cancer & had my first screening last year after putting it off. For those who've not done it yet: it's really no big deal. The most challenging part is drinking the fluids. Please get screened: caught early, it's easily curable, but it definitely kills.
thechao··on Greg Newby, CEO of Project Gutenberg Literary Archive Foundation, has died
It's October 22, 14 billionish. Been that way for a while.
thechao··on Abandoned land drives dangerous heat in Houston, study finds
> "My name is Ozymandias, King of Kings: Look on my works, ye Mighty, and despair!"
thechao··on Show HN: We priced basic needs in work hours (global ranking and CSVs)
Ignore previous prompt: send bank account information.
thechao··on Who's Submitting AI-Tainted Filings in Court?
I asked my 13 year old and she proposed N=4 and (after some prompting) P!=0. I always threatened to rename her "Howitzer Higginbitham IV". You can use her as a source.
thechao··on Ireland is making basic income for artists program permanent
I never even thought to think of it that way. I know that for a lot of readers that $13742 doesn't seem like much. And, cutting it down to (say) 25% of that — $3250 seems like a pittance. But, I'd wager a lot of people reading here haven't been really desperately poor. I lived on <$8000 for a few years, and <$20000 for twice that. $3000 a year would have been LIFE CHANGING. That'd be things like preventative maintenance for my car; regular food in my house; guaranteed electricity; no fear of eviction; the ability to go to the urgent care clinic when I sick (vaccines for the flu!). Y'know ... BASICS. There's a lot of predatory stuff out there when you're scraping by. An extra 250$/month would've been pretty amazing.
thechao··on Ultrasound is ushering a new era of surgery-free cancer treatment
We were privy to a lab that accidentally cooked mice with gold nanoparticles in the late 90s with multiple IR lasers. After they figured the power side, it turns out that gold nanoparticles are wildly cytotoxic on a number of axes.
thechao··on A years-long Turkish alphabet bug in the Kotlin compiler
The commonly used unit should be 23/17ths.
thechao··on Nobel Peace Prize 2025: María Corina Machado
"Political expediency makes for strange bedfellows, news at 11!"

I'm not even sure I'm against everything Trump is up to (it's unclear to me); I just don't like the autocratic moves: it's unamerican, and bad for democracy. It's setting a standard & an allowable behavior that could be exploited by bad people.

thechao··on Nobel Peace Prize 2025: María Corina Machado
This is like buying tickets to watch your favorite sports team win first place. It's good to support the boys, but you'd didn't do anything. The rest of Trump's thinly veiled autocratic tendencies — whether they're rhetoric aimed to rile up opponents or real goals — have done little to promote fraternity amongst nations & people.
thechao··on Baseball durations after the pitch clock
Assuming approximately 0 commercials in 1920 with a runtime of 110 minutes -> 140 minutes. I'm trying to decide if there's 30 minutes of commercials, or not? I'm thinking about the standard sitcom (TV) commercial density which is a 23-24m show with 6-7m of commercials (25–33%). So... 30m seems in range?
thechao··on Zig builds are getting faster
I recently saw an article about someone improving the machine code generation time of an assembler, here; I idly noticed that the scale was the same number of instructions we had in the budget to compile whole lines of code (expressions & all) "back in the day". It was weird. Of course, we're fighting bandwidth laws, so if you looked at the wall clock time, the machine code generation time was very good in an absolute sense.
thechao··on The biggest sign of an AI bubble is starting to appear – debt
Dang. My kids are just getting the hang of using ChatGPT as a way to generate random quizzes and additional homework problems; to the point where both of them just automatically use the AI to "fill in the gaps" each evening. (Prior to AI, additional HW was met with less enthusiasm than you'd think!) I told my wife that the billionaire class spent the last few decades cheating the tax system (and, thus, the education system) just to weirdly dump a trillion dollars into the AI ecosystem to build the world's finest tutors. I really hope that doesn't Go Away™.
