moelf··on Science is a strong-link problem
not to mention there's always the possibility of what's roughly described in _End of Science_, at least for physics anyway.
moelf··on Science is a strong-link problem
interesting to frame problems as strong/weak link, is kinda useful for thinking about certain things.

citing Nobel laureate's take on "if I'm working today I won't..." is not too convinsing

    >In my day you could get a faculty job with 0 postdoc papers
can't imagine how that would work today, the world changes why science as a social activity that has costs can be immune to the change?

Too bad while bad music and bad novels only take up some shelf space and make searching a little harder, science projects costs $$$ and so the real Q is how to distribute $, current approach is not that good and gatekeeps some good stuff out, but what's the alternative?

moelf··on Training open-source LLMs on ChatGPT output is a really bad idea.
what do we say to people who has the argument of "but the web is already littered with spam blog and SEO stuff"

moelf··on OpenAI releases Consistency Model for one-step generation
Think of Stable Diffusion but doesn't need the expensive multi-step diffusion yet still achieve similar result.
moelf··on Why is GPT-3 15.77x more expensive for certain languages?
but the tokenizer is dataset-driven... it tokenize the most common pattern in your dataset to improve efficiency, so it's 100% about dataset?
moelf··on A CERN for Open Source Large-Scale AI
except CERN actually does a lot of things backwards in terms of technology (partly due to our unique needs for hardware, but absolutely no excuse for software).

If what CERN is doing has even the remotest real-world application, CERN would have looked much less world-leading than it is today. European treaty is what made CERN viable -- because otherwise it's very hard to fund ultra long-term, almost no return projects.

AI is the opposite of that and you probably don't want to have a CERN: plenty of $ flowing into AI project without government intervention && you don't want the slowness of CERN.

>I’ve been thinking a lot about how AI can reduce some of the world’s worst inequities.

huh, closeAI is certainly not helping at this moment in time.

moelf··on 20M digits of pi in 1 minute using Julia
it's not using the same algorithm right?
moelf··on 20M digits of pi in 1 minute using Julia
the Julia REPL allows you to type unicode with \blah, also if you use `?` help mode, you can give it a unicode sequence and it will tell you how to type it, so it's nice quality of life

    "Ψ₂ˣ" can be typed by \Psi<tab>\_2<tab>\^x<tab>

moelf··on My Journey from R to Julia
>happens at runtime

is not technically true, because that implies a massive slow-down. instead it's more accurate to say behavior-wise it's always equivalent to a dynamic dispatch, but because Julia's Just-Ahead-of-Time compilation, often you eliminate the dynamic dispatch during run time.

moelf··on Why Fortran is a scientific powerhouse
we're actively trying to move more end-users of high energy physics (HEP) into Julia https://github.com/JuliaHEP/
moelf··on Do simpler machine learning models exist and how can we find them?

All platform is a lie, IIRC a long time ago they actually promised a Linux version, but never realized that.

you're right and it's a pain point for YEARS

moelf··on From Common Lisp to Julia
>languages defined by a standard, not by a single implementation.

any of the IronPython, Cython, Jython worked well enough to be continued and works well with the rich CPython ecosystem 100%?

moelf··on From Common Lisp to Julia
yeah general chicken and egg problem but I guess if we don't collectively take a bit of initiative, we can never have better things!
moelf··on Exploring Mastodon
because that's way too expensive? if you follow every Programming@ on every public instance and nobody is doing the centralized data distribution, you have a all-to-all situation?
moelf··on Ask HN: Why do you hate (or love!?) your language's package manager?
Julia packaging scene has the unique advantage that it handles binary dependency (building and versioning) just like a regular Julia package. For example, CUDA.jl will "just work", and you don't need to manually install some specific version of CUDA for TensorFlow etc. which also makes reproducibility more robust. Where in Python the conda.yml doesn't work across OS/architecture, AND often doesn't track binary dependency (despite that's what Conda is designed to do...)

moelf··on Julia 1.8

moelf··on Julia 1.8
it's called JIT, comparing to R, it probably would speed up some moderately complex calculation by 100x to 1000x, but if you don't have the type of workload, feel free to use R -- people should use whatever suits them the best!
moelf··on Numpy is absurd
Op here, I'd also like to say I blame this on Python's lack of broadcasting syntax, (dot in Matlab and Julia)

Which forces Numpy to be designed in a way to automatically broadcast, guessing what user wants is hard in nested container

moelf··on Numpy is absurd
Julia
moelf··on Numpy is absurd
when built-in array type is not performant nor serves as an interface (abstract class), it's as if it doesn't exist. I guess the point is Numpy predates Python's array by a long shot.

Compare and contrast with languages with built-in N-dimensional array for scientific computing.

moelf··on Numpy is absurd
that's what I'd go for, throw more errors when `__contains__` is called with ambiguity.

but, cough, mature and stable scientific computing foundation?

moelf··on Programming Fonts

moelf··on Go generics are not bad
"not bad" is a weird bar to cross for a language that:

    1. decided generics is not needed
    2. went on for a decade
    3. implemented a version of it that is not performance-sensitive
    3.5. $$ by google
moelf··on Darktable 4.0
I wish the effort is united between dt and rt (and maybe digiKam for management), then we'd have a Blender-level competitor against LightRoom maybe
