<p>EDIT: This was caused by using an old version uv (0.7.3) updating with `uv self update` to the latest version (0.11.2) resolved it. Original message below:<p>While the first form seems to work with `pyproject.toml`, it seems like the second form in the global `uv.toml` only accepts actual dates and not relative times. Trying to put a relative time (either in the form "7 days" or "P7D") results in a failed to parse error.</p>

<p>My understanding is they used to be fairly strict about using a set for 2 weeks before changing, but research has shown very little difference in outcomes down to 1 week.<p>There is some discomfort/soreness for the first few days after switching. My dentist's instructions were to wear each for at least a week and then switch to the next set whenever I wanted after that. Basically at whatever rate I was comfortable/could tolerate. I'm now at set 15 and have switched most of them after a week while a few I delayed a couple of days because I had something happening where I didn't want to worry about any discomfort.</p>

<p>Given that the actual vulnerability seems relatively niche along with it being such a popular library officially maintained by the Python foundation, the scariest line in the advisory is almost certainly:<p><i>The vulnerability was originally reported to the library maintainers on September 12, 2024, but no fix is available.</i></p>

<p>Just a clarifying note, Craig Reynolds is the original researcher for Boids, and he did have a Java applet implementation in the above page. But the original Boids simulation was from 1986, almost a decade prior to Java applets.<p>The original paper, published in 1987, is "Flocks, herds and schools: A distributed behavioral model"[1]. The implementation was done in Lisp on a Symbolics 3600 Lisp Machine.<p>Edit: One quite interesting paragraph from the paper regarding performance:<p><i>The boid software has not been optimized for speed. But
this report would be incomplete without a rough estimate of the actual performance of the system. With a flock of 80 boids, using the naive O(N²) algorithm (and so 6400 individual boid-to-boid comparisons), on a single Lisp Machine without any special hardware accelerators, the simulation ran for about 95 seconds per frame. A ten-second (300 frame) motion test took about eight hours of real time to produce.</i><p>Once again, amazing how far hardware has advanced.<p>1. <a href="https://dl.acm.org/doi/10.1145/37402.37406" rel="nofollow">https://dl.acm.org/doi/10.1145/37402.37406</a></p>

<p>If the PRNG is good enough then shipping floppies full of PRNG output is very much unnecessary. Simply send the seeds used to initialize the PRNG thereby fitting many (~180k of them on a 720kb floppy) seeds on one floppy and save your couriers a lot of risk.</p>

<p>> that your pad generation is actually random<p>The one thing that stood out to me with the original blog post and a quick glance at the code was that it appeared as if the pad was certainly <i>not</i> actually random.<p>Could anyone that has actually understood it a bit more confirm or reject this?<p>Edit: It seems that the random generation can be found starting here <a href="https://github.com/Vulacode/RANDOM/blob/d6a1a1d694b22e6a115b50a6c2d2bada41cda075/RANDOM.BAS#L1262">https://github.com/Vulacode/RANDOM/blob/d6a1a1d694b22e6a115b...</a>
With three methods, one (RAND2) seems to use the basic interpreter rng more or less directly and the other two seem to be fairly simple prngs seeded from the basic interpreter's rng.<p>I don't actually know what the state of basic interpreter rngs was in the early '80s but I would be fairly surprised if they're anything that is secure.</p>
