latexrun does a pretty reasonable job with LaTeX files, and only runs when needed, etc. Would be nice to have this integrated into a build system for plots, data generation, etc.
I don't think that 4o will actually be available for free. It seemed like they were quite careful in choosing their words. My guess is 3.5 is free without an account, and accessing 4o requires linking your OpenAI account.
Frequencies beyond the Nyquist limit alias back to resolved modes. So a combination of the camera plus a human eye to check that the flashing is “fast” (i.e. above the Nyquist limit) should be enough to verify the frequency.
A minor correction: anti-matter is actually regular matter. We understand it quite well, and are even able to create anti-atoms in the lab. On the other hand, dark matter is much more poorly understood: essentially the only evidence we have for its existence are observations of "weird" gravitational effects in the universe.
This has been my conclusion. I've spent the past few weeks polishing my yt-dlp scripts. Honestly, the experience of being able to watch any video I want offline and buffer-free is way better than the default YouTube experience. Sometimes I miss the comments section, but it is probably better for me that I don't have access to that.
That said, I think this take has aged poorly in light of recent history. For instance, Google was started as a small collaboration, but has since grown into an enormous company. Presumably, this growth was (at least initially) the natural result of finding that a couple people can only do so much. For another example, Sublime Text (a for profit text editor written by a small group of developers) is massively less popular than VS Code, which is the bloated work of a small army.
Is it? Every large company has a well compensated CTO whose job it is to think through these sorts of hypotheticals. But “nobody gets fired for choosing Microsoft”, and so the monopoly continues…
The rise in student loan debt can alternatively be explained by increasing concentration of wealth in the hands of a few people. In the past (e.g. 40 years ago corresponding to a graduation date ~20 years ago), more families were able to save enough to cover the true cost of 4 years of college. Now many families are living paycheck to paycheck, and cannot create an emergency fund, much less a college fund.
