epcoa··on Paracetamol disrupts early embryogenesis by cell cycle inhibition
ibuprofen and similar are also much more likely to destroy your kidneys as well and exacerbate heart disease. Intermittent regular dose use is unlikely to cause kidney harm but people get in trouble in two ways: chronic extended use of higher “therapeutic” doses (800mg for ibuprofen) or they have other medical problems weakening kidney function.
epcoa··on Candle Flame Oscillations as a Clock
Just to offer an alternate perspective.

While technically a PIC12 is a computer since it has I/O, tiny storage, a PC and an ALU - it’s hard to even think of it in the same category as what most think of as a computer. IMHO the takeaway is more what the bare minimum it takes to be a computer, which isn’t much. (In other terms, a PIC does not meet the DOOM threshold).

PICs are so old and rudimentary that they started out as peripheral controllers for “real” computers in the 70s. It turns out you can do some useful embedded stuff with a basic chip, but even the newest of these are on 30 year old semiconductor tech at this point.

That may sound jaded, on the other hand I do find mass production of modern level integration and speeds to still be marvelous.

And as an EE, the “white” LED in the candle is more interesting than the uC!

epcoa··on Myths About Floating-Point Numbers (2021)
Correct, divide by zero is one of the original five defined IEEE754-1985 exception. But the default behavior then and now is to produce that defined result mentioned and continue execution with a flag set ("default non-stop"). Further conforming implementations also allow "raiseNoFlag".

It's well-defined is all that really matters AFAIC.

epcoa··on Myths About Floating-Point Numbers (2021)
If dividing by zero has a well defined result that doesn’t abort execution what exactly does “can’t” even mean?

Operations on those sentinel values are also defined. This can affect when checking needs to be done in optimized code.

epcoa··on Why Wisconsin's county highways are lettered, not numbered (2019)
Nobody calls them that in most places in the US, but towns and villages usually have “highway departments” and they’re not the ones managing the interstates and state highways.
epcoa··on Why Wisconsin's county highways are lettered, not numbered (2019)
They’re still county highways, at least according to the person interviewed in the article. It’s even called the Wisconsin County Highway Association.
epcoa··on The surprise deprecation of GPT-4o for ChatGPT consumers
Considering how much d-listers can lose their shit over a puppet, I’m not surprised by anything.
epcoa··on Claude Code IDE integration for Emacs
StackExchange surveys are not “randomized trials” and only qualifies as the lowest quality research.
epcoa··on Claude Code IDE integration for Emacs
While not going to argue that vim is niche, I don’t think it is. StackExchange surveys are likely highly unrepresentative and lack external validity. I do not believe 40% of developers use vim based on such an unvalidated and likely biased study.
epcoa··on Once a death sentence, cardiac amyloidosis is finally treatable
> The more common form according to my wife

Not sure what relevance the source has here, but it’s not correct. Primary (AL) is the most common in the developed world and secondary (AA) elsewhere. There are some foci of ATTR but it is by far not the most common.

And your stomach lining. Even better if you’re already on a DOAC for Afib.

Where are they marketing it as native?
epcoa··on Java was not underhyped in 1997 (2021)
Well all the parts that you didn’t write in XML and XSLT, etc.
epcoa··on The borrowchecker is what I like the least about Rust
Lua has petered out a bit but it has been used as a scripting and config language for a ton of games and commercial embedded. Not a hobby language, not typically a main implementation language but that doesn’t mean no commercial use. posix/bash shell isn’t a hobby language either, but unless you’re Tom Lord or something (RIP) you’re not doing the entire project in it.

Do realize that luajit for years was bankrolled by corporations.

epcoa··on LLM Daydreaming
Run ML of any combination and form in a for loop for higher order is one of the most obvious avenues. If it worked you would have heard about it a long time ago.
epcoa··on LLM Daydreaming
The step 3 has been shown to not work over and over again, the “find interesting connections” is the hand wavy magic at this time. LLMs alone don’t seem to be particularly adept at it either.
epcoa··on Lua beats MicroPython for embedded devs
This is just an ad in a trade rag masquerading as an article or something. It's an ad for that Xedge Lua framework.
epcoa··on Dyson, techno-centric design and social consumption
The Miele cordless stick vac is a piece of crap unfortunately. Real missed opportunity.

Pauling spins furiously in his grave in approval.
epcoa··on 2025 ARRL Field Day
> Although Field Day is not a contest, these guys really really wanted to finish in the top 10 for class 2A.

That’s literally a contest. If the scoring was private maybe I’d agree.

Field Day may serve other purposes too, but it’s a contest, if not purely so.

epcoa··on From SDR to 'Fake HDR': Mario Kart World on Switch 2
Not sure why you would associate “white collar” with poverty. While technically there are poor office workers, this is not the typical association.
epcoa··on SkyRoof: New Ham Satellite Tracking and SDR Receiver Software
What’s the point being made here? Is there anything on there that is similar in design?

The only thing that seems kind of similar (sdr-radio.com) is also Windows only.

epcoa··on IRS Direct File on GitHub
Other than the flourish of adding some Scala to enterprisey Java there is absolutely nothing atypical about this bog enterprisey application. It’s a JS/TS/Java app, nothing else stands out.

Listing every config language and a few lines of CI or whatever scripts shit is misleading.

I see nothing other than typical boring enterprise/big gov crap here (which is fine, and expected).

epcoa··on Modification of acetaminophen to reduce liver toxicity and enhance drug efficacy
I’m not going to shit on it, nothing wrong with going into the family business - but it isn’t a complete coincidence that her dad is a PhD biochemist at UT Tyler.
epcoa··on Using unwrap() in Rust is Okay (2022)
> It is tempting to do the fast thing when you are on a tight schedule.

The alternative option in C or C++ is to do some undefined behavior. Before a pile on, yes of course you can avoid it but the rush option is usually going to be the equivalent of unwrap anyway, and Rust does make it quite a bit harder to invoke undefined behavior.

epcoa··on The Beauty of Having a Pi-Hole (2024)
What is an arbitrary TCP port? Ports in isolation from an IP address aren't inherently arbitrary, they're nothing, and the IP:port pair is arbitrary. Once you allow connections to any host on the internet the port doesn't really matter - you can do whatever nefarious shit over port 80. And not allowing apps to connect to external internet servers seems pretty limiting.

Meh, I used to keep printed copies of autotools manuals. I sympathize with all of these people and acknowledge they are likely the sane ones.

epcoa··on C++26: more constexpr in the core language
Why would you need to do that though if you can static_cast?
epcoa··on How a 20 year old bug in GTA San Andreas surfaced in Windows 11 24H2
By the 2000s, portability was a concern for most titles. Certainly anything targeted at a rapidly changing console market back then.
