A fun one: PostgreSQL uses an adopted version of Tcl's regular expression engine, written by Henry Spencer. Tom Lane seems to think it was an impressive piece of work, and patched it up from time to time. https://en.wikipedi

The key thing is Postgres does handle enomem well and does a nice rollback rather than crashing the server and entering crash recovery. It’s one of the few programs that does. Exceptions for the exception. Even a revised heuristic that only

I always like these randomized/semi-randomized network papers. Here's a little known one you might enjoy if you liked this one. https://repositorio.unican.es/xmlui/handle/10902/23594

I've been tying this for years. Good knot. I only have failures if I hit a snag (and no easy-release knot is going to be able to get around that)

I enjoyed my work with Scheme, having received my instruction in the early 2000s. I'm not a functional language or lisp language advocate in any way, and I don't even dislike Python for professional work, but I do regret that it i

Fun fact about silver, besides its heavy industrial footprint, which you mentioned: the supply is dominated by Mexico. There have been some, uh, erratic words about Mexico from the people in the position to affect trade policy and foreign p

For those of you with this handy technology, the mobile phone, in the United States: you have an IPv6 address without NAT. Some of you even exist on a network using 464XLAT to tunnel IPv4 in IPV6, because it's a pure IPV6 network (T-Mo

the main area I'd like to see some departure from beads is to use markdown files (or something) to be able to see the issue context/comments better in a diff generated by git. The other area I'd like to see some software eng

that's one reason I am less worried about him than some, although, I don't want to say that only to have something bad happen to him, that is, a form of complacency. Just because (say) Boltzmann and Cantor had useful insights alon

I use beads quite a bit, but not as steve intended. And definitely the opposite of "Gas Town," where I use the note-taking capability and integration with Git (that is, as something of a glorified Makefile and database) to debug c

That's a lot of financial devices painted with a broad brush, and I think the charge that so may central banks are knuckled under with fiscal dominance is simply not sustainable. The ones that are, we tend to hear about. Because there&

You don't even need to trust CPI alone when looking in history, where things have evened out a bit: we have historical short-term bond yield data, even the yield curve: people bidding on short periods with the safest debtor expecting c

It's not very convincing, though: there's a huge runup in gold prices (as is often the case) between 2023 and the present, and a long do-nothing period before that (also often the case). The major consumers of gold are about: 50%

Public Sans seems like a good candidate for a new "web safe" font. Perhaps one new web safe font per twenty five years is not too much. From there, it can percolate to the word processor and pdfs, and finally: government standard

The biggest run classified nuclear stockpile loads, at least in the US. They cost about half a billion apiece. And are 30 (carefully cooled and cabled) megawatts. https://en.wikipedia.org/wiki/El_Capitan_(supercomputer)

that also popped out at me: binding that many parameters is cursed. You really gotta use COPY (in most cases). I'll give you a real cursed Postgres one: prepared statement names are silently truncated to NAMEDATALEN-1. NAMEDATALEN is 6

I think it's pretty funny because, for example, Katalin Karikó was thought to be working in some backwater, on this "mRNA" thing, that could barely get published before COVID...and, the original LLM/transformer people we

One of the things I think about sometimes, a specific example rather than a rebuttal to Carmack. The Electron Application is somewhere between tolerated and reviled by consumers, often on grounds of performance, but it's probably the s

Seems like an exponential backoff rule would do the job: I'm sure crashes happen for all sorts of reasons, some of which are bugs in the bot, even on non-adversarial input.

GP is more or less correct. Building and owning an institution that finances, racks, services, networks, and disposes of servers, both takes time and increases the commitment level. Hetzner is month to month, with a fixed overhead for fres

It varies by system. As the legendary (to some) Kelly Johnson of the Skunk Works had as one of his main rules: > The inspection system as currently used by the Skunk Works, which has been approved by both the Air Force and the Navy, meet

There is such a prefix, though, but the problem is the end user devices themselves (or a few applications) are not always modern enough to have decent operation with a IPv6 stack. Less so these days, though. See https://en.wikipe

The Ruby we write is quite strange by the normal reckoning. In particular, it has 100% branch coverage. Being able to do this affordably is one reason I use it. A fair number of the dependencies we have also have 100% branch coverage, beca

Sure, it reduces costs quite dramatically to be able to do stuff like this: upgrade_check_ssh = ->(vmh) do p [vmh.ubid, vmh.created_at, vmh.sshable.host] vmh.sshable.cmd(<<BASH) set -xeuo pipefail sudo apt

UBI is generally not metered by "%" but some flat quantity of money, whether nominal or real. That is, like a "head tax," but...negative. In that common formulation, it would compress consumption by the entire tax+benefi

You are looking for the term "effective marginal tax rate." https://en.wikipedia.org/wiki/Effective_marginal_tax_rate To give a sense how much benefits code and tax code have in common, see this worksheet for

yeah, that one is a path dependency issue, re: postgres. I'm not sure if it's well reasoned past inertia after the initial "it's new, let's not throw the entire user base into it at once", but at the very least
