mjhay··on Too many R packages: CRAN is inundated with submissions
I’m a big fan of Polars. It’s really fast and memory efficient. With the lazy streaming functionality, I’ve been able to easily process 1 Tb+ data on a single machine (you do have to be careful to not do any operation that would cause the whole DF to materialize in that case).

It’s certainly miles better than Pandas, which has a terrible API in addition to being comically inefficient. In my group, we generally use it for any new work, and have also swapped out pandas for polars in critical spots of our existing code - the latter giving a huge benefit relative to the amount of work it took.

I largely agree with you on SQL being the common denominator, but there are some things that are just awkward in SQL, and much easier to do in Python or other general purpose language.

mjhay··on Too many R packages: CRAN is inundated with submissions
I’m not saying it doesn’t have flaws, but the tidyverse is still the most coherent and functional ML/stat computing ecosystem I’ve ever used. R packages outside of the tidyverse can get pretty gnarly. Even the R stdlib is usually considered to be inconsistent and riddled with legacy cruft.
mjhay··on Millimeter wave technology drills 100 meters into granite
They kind of have to shoehorn “AI” in there have any hope of raising capital these days.
mjhay··on VPN ban update for UK households as government looks at 'age-gate'
The onus is you to show it makes children safer - you’re the one advocating these privacy-harming rules.
mjhay··on GLM 5.2 Performance Benchmarks
There’s no way Anthropic can keep jacking up the prices like this for every marginally better model. I think even tokenmaxxing companies are going to soon balk at $50/million output tokens.
mjhay··on What even is food authenticity? Why we guard carbonara, and flatten chicken rice
Recipes were the province of the wealthy. The average person would have had a very repetitive, bland, and potentially malnourishing diet. They might have had some herbs or even foraged like you say, that still is very bland and boring compared to what we’re used to.
mjhay··on Rome Fell and Nobody Noticed
Ironically enough, the thing that really did Roman Italy it was Justinian’s reconquest. The Gothic War was absolutely devastating. Yersinia pestis didn’t help either, of course.
mjhay··on The Structural Barriers to AI Lawyers
It’s not so well-paying anymore, especially given the onerous education requirements. The exception is for the few who get hired in biglaw firms
mjhay··on California leaders report four to six weeks worth of gasoline and diesel supply
An export ban wouldn’t really help much: US oil production is (now) predominantly light crude, while US refinery capacity is oriented towards heavy crude from the gulf or Venezuela.

We produce more oil than we use, but we can’t refine it all.

mjhay··on Grand Theft Oil Futures: Insider traders keep making a killing at our expense
How do you do that when the ruling class has a vested interest in preventing it?
mjhay··on The fun has been optimized out of the Internet
The kind of consumer thrift stores want to sell to. They don’t have to be real.
mjhay··on Two millionth electric car registered as market rebounds from tax changes
Coulda fooled me. From what I’ve seen, it seemed like they were dragged to electric kicking and screaming after other options didn’t pan out - even with assistance from regulators. Germany has a severe problem with rational consideration of energy issues.
mjhay··on The fun has been optimized out of the Internet
Thrift and vintage stores have been pivoting to the premium consumer as well.
mjhay··on Snowball Earth may hide a far stranger climate cycle than anyone expected
The impact hypothesis for Younger Dryas isn’t really tenable. Among other things, the climate effects of a large bolide impact would be global, whereas Antarctica actually warmed during YD. This “Polar See-saw” pattern is easily explained by a northerly meltwater pulse hypothesis, but not a bolide.
mjhay··on The Image Boards of Hayao Miyazaki
There’s so much magic, for lack of a better word, in those illustrations. Miyazaki is really one of a kind.
mjhay··on Stackoverflow launches a new AI-first experience (Beta)
I think they’re just trying to do anything to survive, since they’re getting their lunch eaten by LLMs trained in stack overflow posts.
mjhay··on South Korean ex president Yoon Suk Yeol jailed for life for leading insurrection
I forgot that satire was dead.
mjhay··on 99% of adults over 40 have shoulder "abnormalities" on an MRI, study finds
wow, egg on my face!
mjhay··on South Korean ex president Yoon Suk Yeol jailed for life for leading insurrection
I suggest you re-read the Constitution. The First Amendment protects people from any negative repercussions whatsoever resulting from their free exercise of certain kinds of speech.
mjhay··on Antarctica sits above Earth's strongest 'gravity hole' – how it got that way
It’s also probably the best single method of inferring ice sheet mass balance over wide areas.

Alcohol also reduces awareness of heart attacks.

mjhay··on Officials Claim Drone Incursion Led to Shutdown of El Paso Airport
Curious, because the martyrs were Mexican high-school students.
mjhay··on AI-First Company Memos
The executives pushing AI use everywhere aren’t basing it on actual performance (which is an orthogonal concept). It’s just the latest shiny bauble.

Regarding Western military procurement,

“We have such sights to show you!”

mjhay··on Mozilla is building an AI 'rebel alliance' to take on OpenAI, Anthropic
Correct, it’s to make their non-profit executives rich.
mjhay··on Did a celebrated researcher obscure a baby's poisoning?
The idea of an opioid OD from breast milk immensely strains credulity in the first place. Such a claim should really have been put under much more of a microscope.
mjhay··on Pandas 3.0
It’s a typical experience. Polars is fast, and Pandas is very slow and memory-hungry. It would be one thing if Pandas had a good API, but it doesn’t.
mjhay··on TSMC Risk
A conventional missile or even missiles is not going to destroy a huge gravity dam like that. They are incredibly tough structures and missile warheads aren’t big. We’re talking concrete hundreds of feet thick.
