uolmir··on “I just chose words carefully”
He managed to create the ultimate version of form over function. All hail Lorem Epsom.
uolmir··on 'We mould trees to grow into the shape of chairs'
So elves in dwarf fortress.
uolmir··on All Look Same?
Seriously. I remember distinctly playing with this in 2004-5.
uolmir··on What an unprocessed photo looks like
This is a great write up. It's also weirdly similar to a video I happened upon yesterday playing around with raw Hubble imagery: https://www.youtube.com/watch?v=1gBXSQCWdSI

He take a few minutes to get to the punch line. Feel free to skip ahead to around 5:30.

uolmir··on Ask HN: What did you read in 2025?
I know what you mean by your comment, but you might want to give catch 22 another try sometime. I'd say that the start with the Texan is far from the best the book gets. Reading it, I think you'll find Yossarian more and more understandable and the situations more and more bleakly comic as you go.

Or don't. There's no end of great novels out there.

uolmir··on High school student discovers 1.5M potential new astronomical objects
Several of the candidate variable objects are characterized in the results section of the paper. The model is also tested for effectiveness against synthetic data. It appears to be a useful method and the paper describes a plausible path for it to aid future discovery.
uolmir··on NYC congestion pricing cuts air pollution by a fifth in six months
Everywhere? This is a crazy thing to claim. I was also recently in Japan and I never took a car anywhere. I'm sure there are particular routes that are badly served but come on.
uolmir··on No science, no startups: The innovation engine we're switching off
> In fact up until a recent funding method change from the Trump Administration, most grant money was subject to "overhead"--a nebulous nonsensical accounting trick that allowed the university administration to get upwards of 60% of the dollars that are earmarked for grants.

We're better than this here. Don't spread misinformation. First of all overhead is listed as a percentage, such as 55% or 60% or whatever but the university doesn't get that fraction of the total grant. You work up the so called direct costs, ie the line item salaries of the researchers, the reagents, etc. and then the overhead is 60% of that figure. So it would work out to be 38% of the total dollars granted.

It's also not a trick. It's a negotiated amount that is supposed to avoid each grant requesting some amortized fraction of the cost of office space and other necessary but shared expenses.

I and most people agree that's it's possibly too high, but it's ignorant to treat it like a scam.

uolmir··on CCTV footage captures the first-ever video of an earthquake fault in motion
Although that land would have already been under water.
uolmir··on The last step in a long process on “arsenic life”
Important context to be found in the reporting on this saga, e.g., https://www.nytimes.com/2025/07/24/science/arseniclife-retra....

In short, the authors and NASA strongly disagree with the decision to retract and argue that this is clearly outside of the typical norms for what retraction is supposed to represent. A paper being wrong isn't and shouldn't be the standard for retraction, particularly in this case when the original paper was published with multiple technical responses and rejoinders.

uolmir··on What's happening to reading?
One of the best! If memory serves there was a This American Life segment excerpted from it too (https://www.thisamericanlife.org/195/transcript).
uolmir··on NIH will eliminate many peer review panels, lay off scientists overseeing them
From the article this seems much less bad than the headline might imply. This idea predates trump and it does not eliminate scientific review of proposals. That said, whether the cost savings itself is worth what might be a diminishment in review quality is hard to say. I can only comment from the NSF side of things to say that peer review of proposals is a mixed bag and will unavoidably run into human error and individual predispositions regarding scientific importance so maybe this isn't a bad approach to try.
uolmir··on Diablo hackers uncovered a speedrun scandal
There have been several of these deep dives into manipulated speed runs and they seldom disappoint. Since we are on HN, I'll mention another mathy one that was summarized by Matt Parker: https://www.youtube.com/watch?v=8Ko3TdPy0TU
uolmir··on Her Discovery Wasn't Alien Life, but Science Has Never Been the Same
Reflections on science in the internet age and a debate on the meaning and appropriate use of retraction.
uolmir··on In some scientific papers, words expressing uncertainty have decreased (2023)
That's good advice in that context and speaks to the difference in standards of evidence between normal expository or persuasive writing in school and scientific writing. In a scientific paper if you assert something it's important to flag to the reader what kind of claim this is, eg something demonstrated by other research, something that directly follows from your evidence, or something that could possibly be true given prior knowledge and your evidence.
uolmir··on Studying Stones Can Rock Your World
Very true (I imagine) and similar to the popularity of "roadside geology" books.
uolmir··on Increasing Retention Without Increasing Study Time [pdf]
This is good stuff but I'll say that it isn't as comprehensive as all that. These studies and findings are almost entirely focused on simple recall knowledge (isolated facts, vocabulary). That's an important part of learning certainly and it informs research on learning higher order concepts but it's not the full story.

Just to name one example, folks might look into research on conceptual change theory (eg Chi or Posner). This theory helps explain why a concept like electricity is so challenging to learn. The reason, in brief, being that naive conceptions make a category error and think of electricity as a thing rather than a process. And this theory then informs instructional practice. Specifically, teachers should be aware of difficult concepts and should design activities that force students to confront the contradictions between their naive models and more accurate/complete ones.

Mickie Chi also has fascinations research on active learning (ICAP) and related work on the effectiveness of peer learning.

uolmir··on Moments in Chromecast's history
This is gonna be me if or when my quite functional dumb LG from 2012 ever gives up the ghost. I just don't see the appeal of smart TVs when that functionality can be outsourced to a cheaper modular device.
uolmir··on Your Driving App Is Leading You Astray
I think the author probably exaggerates her point a bit (fair enough; she's an opinion writer), but I do find it appealing to imagine that OpenStreetMap would have broad buy-in and would lead to more innovation and diversity in the digital maps marketplace.
uolmir··on Man-Computer Symbiosis (1960)
Yeah. I think if I read Dream Machine first I would have enjoyed Wizards less. But some of the history was new to me which meant that I enjoyed Wizards for those aspects and then Dream Machine for the detailed look into why it happened.
uolmir··on Man-Computer Symbiosis (1960)
It is one of my favorites. I actually came to it via "where wizards stay up late", which I would also recommend although it doesn't have the depth and insight of dream machine.
uolmir··on My finetuned models beat OpenAI's GPT-4
I don't know your circumstances but often you retain the right to distribute a "post print", ie the final text as published but absent journal formatting. A dissertation should fit that definition.

uolmir··on Mathematicians and the Selection Task (2004)
This result reminds me of a paper I read last week via Andrew Gelman's blog [1]. It's a very thorough review of the, so called, bat and ball problem and is an up to date summary of something brought to many people's attention via Kahneman's Thinking Fast and Slow. As other commenters have suggested, the most reasonable explanation for the mathematicians to get this problem wrong is something more like carelessness than a lack of logical reasoning ability.

uolmir··on Becoming an Amateur Polyglot
You may enjoy this page: https://en.wikipedia.org/wiki/Evidentiality

As an English speaker myself it's astonishing the number and range of features that other languages have built in, so to speak. Years ago I took Latin and the idea of declension just blew my mind. And that's basic in the grand scheme.

uolmir··on Scientists solve long-standing mystery surrounding the moon's 'lopsided' geology
Great article. As someone with a geology background working in an Earth and space science department, I've greatly appreciated everything I've learned from the planetary scientists and meteorite researchers. There's just so much that we now understand about how our solar system formed and arrived at its current state. The explosion of exoplanet research on top of that and how those two fields inform each other has also been exciting to follow.
uolmir··on Amazon ditches 'just walk out' checkouts at its grocery stores
Ah yes, the famously objective field of economics.
uolmir··on Confirmation of ancient lake on Mars
I think this can be seen as a change to acknowledge the need for context in order to make a robust (and hopefully correct) argument for possible evidence of life (fossil, trace, or otherwise). In all likelihood you're not going to find this uncontestable smoking gun and so you're going to need your robot geologist to collect much more than one sample in one place in order to rule out alternative interpretations. The Viking approach doesn't get you that.
uolmir··on Things I learned from teaching
Low content reply I know but it's great to see ICAP having the mindshare to appear in this discussion on HN. It's such a great paper and concept. I also think it has a lot to offer practitioners by making "active learning" a defined and delineated idea.
uolmir··on Friends don't let friends make bad graphs
I hadn't seen that, but I was going to recommend this recent paper: https://journals.sagepub.com/doi/full/10.1177/15291006211051...

At a glance of the medium article, they seem to have the same perspective on these issues, so the one should complement the other.
