JohnKemeny··on Wikipedia as a Graph
If you were working this to be the first to do it, I have bad news...

One of our projects in algorithms/data structures was to do a BFS on the Wikipedia dump. In 2007.

Emacs has an artist-mode, you know.
JohnKemeny··on A visual introduction to big O notation
n log n is a lot like n, in that if n less than a trillion, n log n is at most 40•n.
JohnKemeny··on A visual introduction to big O notation
You can simply say grows as n⁷. Although people will understand what you mean by saying O(n⁷), O is an upper bound, not a lower bound.

What you should say if you want to be correct is it grows as Ω(n⁷).

JohnKemeny··on Busy beaver hunters reach numbers that overwhelm ordinary math
Okay, I see what you mean.

It really hinges on what is meant by "this question", i.e., Given the code of a computer program, can you tell whether it will eventually stop or run forever?

If what's given to you is the code and its input, then I think the statement's correct.

However, if the input is assumed to be either the code itself or any other fixed thing, then I agree with you.

"this question" is Given the code of a computer program, can you tell whether it will eventually stop or run forever?

It is indeed the Halting problem. (Except that they forgot to state what the input is (the code itself).

JohnKemeny··on What are OKLCH colors?
OKLCH: a color model based on OKLab (a perceptually uniform color space) where you control Lightness, Chroma (saturation), and Hue.

"OK" because "it does an ok job" according to its creater Björn Ottosson.

JohnKemeny··on Crimes with Python's Pattern Matching (2022)
Are you suggesting to bump to Python 4 in order to be able to write `{}` instead of `set()` (or `{/}`) and simultaneously break all existing code using `{}` for dicts?

JohnKemeny··on Emacs as your video-trimming tool
Emacs is an elisp interpreter.
JohnKemeny··on I Prefer RST to Markdown (2024)
Oh, you mean that a PDF cannot be resized? Because the LaTeX document itself is very simple to "resize", by changing paper type, font size, num columns, etc, and you don't have to compile to PDF, you can compile to EPUB or HTML, if you prefer that over PDF.

But, yes, PDFs are intrinsically non-resizable.

Is this the organization on GitHub?

Did they recently rename to Voided Org?

JohnKemeny··on FFmpeg 8.0 adds Whisper support

JohnKemeny··on FFmpeg 8.0 adds Whisper support
Whisper supports adding a context, and if you're transcribing a phone call, you should probably add "Transcribe this phone call with Gem", in which case it would probably transcribe more correctly.
JohnKemeny··on Why does AI feel so different?
From what I've read, AlphaFold2 is a minor improvement over other solvers, and only in some cases. It makes many more mistakes and misleading results than classic solvers.

But don't take my word for it, it's way outside of my area of research.

I recommend this Better Offline episode:

JohnKemeny··on Why does AI feel so different?
Exactly. The tech itself isn't driving the mission --- the funding model is. "AI" right now feels less like the internet in ’95 and more like crypto in 2021: massive hype, vague promises, and any social benefit is incidental to keeping the capital flywheel spinning.
JohnKemeny··on Why does AI feel so different?
The article keeps referring to "AI" as if it's a coherent, agreed-upon thing. It's not. "AI" is a marketing term that's been applied to whatever happens to look impressive at the moment---right now, that's LLMs. There's no settled definition, no unified discipline, and lumping everything from generative text models to actual robotics under the same label just obscures the discussion. If we're talking about LLMs, let's call them LLMs.

And let's be real: we're in a bubble. There's zero evidence that LLMs have produced a measurable productivity boom. If anything, they're net negative in many contexts---encouraging shallow engagement, short-circuiting the learning process, and making knowledge workers more dependent on stochastic parrots that frequently hallucinate. We've replaced "look it up" with "ask the oracle," and the oracle can't reliably tell fact from fiction.

The hype cycle will keep burning cash until someone admits the emperor's wardrobe is ... speculative at best.

JohnKemeny··on Scientific fraud has become an 'industry,' analysis finds
This completely undermines the purpose of peer-reviewing, though.

If it's necessary to do your own peer-reviewing for a publishing house, it could just as well be arxiv.

JohnKemeny··on The Whispering Earring
What began as a complaint about HN’s interest in Scott Alexander devolved into a prolonged, hostile, and circular argument about whether certain reproductive choices are a form of eugenics, whether that’s compatible with utilitarianism, and whether utilitarianism itself is morally bankrupt.

Neither side persuades the other, and the thread becomes more about rhetorical sparring than the original topic.

JohnKemeny··on The Whispering Earring
Don't take my word for it. Do your own research into whose ideologies you'd like to adapt.(*)
JohnKemeny··on The Whispering Earring
Hey, don't take my word for it. Do you own research into worse ideologies you'd like to adapt.

I'm just planting a seed.

JohnKemeny··on Scientific fraud has become an 'industry,' analysis finds
Why would you want your stuff in PLOS? That's a huge red flag on a CV. Why not put it on (bio)arxiv and be done with it?

It's not peer reviewed in either case.

JohnKemeny··on Scientific fraud has become an 'industry,' analysis finds
Also PLOS ONE and a whole bunch of IEEE journals.

gptel-mode (I have it at C-c L) is great!
