moelf··on F3: Open-source data file format for the future [pdf]
Not in physicists' future! /jk. Exabytes of data produced in the next two decades at the Large Hadron Collider will be stored in a format homemade by CERN: https://cds.cern.ch/record/2923186/

oh right, it's just AMD Zen2...
moelf··on Baldur's Gate 3 Steam Deck – Native Version
>Larian does not provide support for the Linux platform. The Steam Deck Native build is only supported on Steam Deck.

huh? but Steam Deck is just normal Arch Linux with x86_64 ~~aarch64~~?...

moelf··on The Expression Problem and its solutions (2016)
> operator overloading, while it can make for cute-to-read code, isn't really a good idea for code readability and maintenance

so should we write `add_int_int(1,1)` and `add_int_double(1, 1.0)` and `add_double_double(1.0, 1.0)`?...

moelf··on The Expression Problem and its solutions (2016)
this is counting it as if O only takes an argument, which is single dispatch, which OOP covers already (the `self` is the single argument).

In practice, Multiple Dispatch shines when you have 1) more than one argument type (duh) 2) higher order `O` operation [1]

[1]: think of a numerical routine that calls eigen or something, and you want eigen to exploit the matrix's type, such as symmetry or upper-triangular, and this is encoded as a matrix type)

with juliac.jl and --trim, hello world is now 1MB and compiles in a second.

more realistic examples of compiling a Julia package into .so: https://indico.cern.ch/event/1515852/contributions/6599313/a...

>I can't help but think we should bet on sth like Mojo instead for the long run.

JAX or Julia hopefully.

moelf··on Framework Laptop 16
I think a large economic value also comes from repair-ability. If nothing ever breaks (until battery dies), I don't think anyone can compete with entry level MacBook in terms of experience/price.
moelf··on The two versions of Parquet
yeah except this new RNTuple thing is really really similar to Apache Arrow

This is Jupyter but without Julia :(

moelf··on White House loyalty rating for companies
>I don't think this is any different from lobby groups

for starter, lobby groups cannot issue executive orders just start and stop tariffs and government grant willy nilly

moelf··on I deleted my entire social media presence before visiting the US – I'm a citizen
>set all their social media to private before going.

https://www.npr.org/2025/06/19/g-s1-73572/us-resumes-visas-f... : All students applying for a visa will need to set their social media profiles to "public," according to a post Wednesday on the State Department's website

even gemma3:12b gets it correct:

~> ollama run gemma3:12b-it-qat >>> ffmpeg command to convert movie.mov into a reasonably sized mp4

Here's a good ffmpeg command to convert `movie.mov` to a reasonably sized MP4, along with explanations to help you adjust it:

```bash ffmpeg -i movie.mov -c:v libx264 -crf 23 -preset medium -c:a aac -b:a 128k movie.mp4 ```

*Explanation of the command and the options:*

>For now, that's the entire collaboration component.

And LaTeX has this for free? It's separated concerns, I think the analogy is Overleaf and LaTeX but just happened to be made by the same group of folks, it doesn't have to go down the monetization-at-the-cost-of-your-user route.

>just budget cuts

NSF is getting a 50% budget cut, at some point, you cut enough budget, it doesn't work.

$20k can't get you that many PhD. Even PhD students, who's nominal salary is maybe $3-5k a month, effectively costs double that because of school overhead and other stuff.

this. Even something as singular as the prediction of the Higgs boson was ~simultaneously reached by different groups(!) of people https://en.wikipedia.org/wiki/1964_PRL_symmetry_breaking_pap...
moelf··on Muon's magnetic moment exposes a hole in the Standard Model, unless it doesn't
>The task before the Muon g-2 Theory Initiative is to solve these dilemmas and update the 2020 data-driven SM prediction. Two new publications are planned. The first will be released in 2025 (to coincide with the new experimental result from Fermilab). This will describe the current status and ongoing body of work, but a full, updated SM prediction will have to wait for the second paper, likely to be published several years later.

a bit unsatisfying, basically the Muon g-2 Theory Initiative which gave us the 2020 prediction that turned out to be wildly different from FNAL measurement is going to publish an updated version of the prediction after FNAL releases their final result.

it means the Theory Initiative will have a target that will never move to aim for when working out their final SM prediction

moelf··on Typst 0.13 is out now
and there's no nice way to insert PDF using WebASM, which is their first-tier support and monetization platform (i.e. 1st party Overleaf)
moelf··on Typst 0.13 is out now
>let you insert chunks of TeX

Honestly a better first step would be getting inserting another pdf plot to work, but seems hard https://github.com/typst/typst/issues/145
