@cemerick generally I'd expect those two tags to be pretty strongly negatively correlated, and the evidence suggesting that SBF is an exception seems to be at best extremely scanty

@cemerick makes sense, quant interns from a prop trading firm are about the most likely people you could imagine to do a fintech startup, and then they'd hire their past colleagues

@larsks that link works OK for me, maybe she's blocked you or something

@cemerick did jane street have a relationship with FTX?

@0x7f I hadn't heard!

@Decodoku I hate to be That Guy, but are you also going to put them on the Internet Archive? I think they might have a better chance of being preserved for the ages there.

@llbbl But ActivityPub is an open protocol, there's even a W3C TR since 2018!

@ReesMcGrory Well, I guess that makes you a learned philosopher, then!

@climagic Is there a link to elsewhere?

@llbbl it'd be great to have an alternative that can run in a $5/month DigitalOcean droplet, no?

@kate I can see a slowdown in supercomputer investments being a factor for a departure from the trend, but not a change in the exponential trend, which (IMHO) mostly depends on improvements in semiconductor fabrication technology making it possible to improve price-performance by 30x or 200x over a decade.

I mean, it's not *absurd* to imagine a progressive reduction in the economic scale of big supercomputer projects by a factor of 7x over a decade. You could imagine it happening if, for example, governments around the world systematically deprioritized nuclear weapons programs because they considered military conflict to be increasingly unlikely. I just don't think that's the world we live in since 2010. If that was the cause, I think you'd expect growth to eventually return to the previous exponential growth rate once spending stabilized at a lower level.

@publicvoit Likewise!

If you're interested in seeing how #LotusAgenda did things, there's a [slow-paced #demo on YouTube starting at 8'16"](https://youtu.be/GsJzRv-UDUM?t=496) The previous several minutes are mostly an explanation.

Like, *very* slow paced; he [finally adds an item at 17'28"](https://youtu.be/GsJzRv-UDUM?t=1048). Later he demonstrates [auto-tagging based on text content](https://youtu.be/GsJzRv-UDUM?t=1318) and [at 37'36"](https://youtu.be/GsJzRv-UDUM?t=2256).

A thing I'd forgotten is that when you're adding an item in a view with a column for some category C, you can type a new value D into that column to create a new subcategory D within C.

(He also demonstrates its features only peripherally related to #tagging, like [an item being sorted on entry](https://youtu.be/GsJzRv-UDUM?t=1239), [adding a note to an item](https://youtu.be/GsJzRv-UDUM?t=1095), and [setting a value in a numerical category](https://youtu.be/GsJzRv-UDUM?t=2152).)

@publicvoit In Agenda there's a "subcategory" relation, which is used for three things.

First, if A is a subcategory of B, then you have a logical implication: if an item has category A, it also has category B.

Second, in a table view, you can use B as a facet, with item values for that facet being A and B's other subcategories; this permits grouping items by B or adding a B column.

Third, you could optionally make B a "mutually exclusive" category so that an item can belong to at most one of its subcategories; this is especially useful if you want to use it for grouping or in order to tune your automatic classification rules. If you didn't do that, you might have items that were tagged with more than one of B's subtags, so in a table view you might end up with a cell with multiple values in it.

This simple model got more complicated in Agenda 2 when they added categories with associated values (for things like dates, money amounts, and temperatures.) Probably it would have made more sense in that paradigm to replace mutually exclusive subcategories with an enumerated data type.

@publicvoit With respect to Hypercard, the only things it has in common with Agenda are that it runs on a personal computer and that you can store data in it and search that data. Hypercard is a card-based graphical hypertext system embedding a high-level scripting language and a data entry screen system; Agenda is a faceted browser of text snippets that classifies them into a faceted tag hierarchy using a user-defined set of text matching rules and can't handle graphics.

@preposterior What's the difference between data science and statistics? I've been trying to figure this out from a distance for a few years.
