Valued customer at Ralphs.

You can find meanness in the least of creatures, but when God made man the devil was at his elbow. A creature that can do anything. Make a machine. And a machine to make the machine. And evil that can run itself a thousand years, no need to tend it.

tomjakubowski··on How accurate have Ed Zitron's AI skeptic predictions been?
the dates of his articles (well, month and year) are all here: https://danluu.com/
tomjakubowski··on Human Slop
You wouldn't need to read all of it to glean that it's slop. Merely a skim or even less signal than that is needed, like simply seeing that it's a multi-paragraph post on LinkedIn. I suppose even surface-level engagement with slop causes some psychic damage, though.

tomjakubowski··on Two German airport workers die of malaria after 'mosquito arrives on plane'
There were malaria epidemics in even quite temperate parts of Europe up to the mid 20th century, including Bavaria and even England, and it was endemic to parts of Italy and Greece. P. falciparum was found in bone samples of the Medicis.

tomjakubowski··on The Tariff Cost: analysis of the costs to Americans from new tariffs on Canada
A handful of people I used to work with lost their US manufacturing jobs in 2025 by exactly this mechanism. Their job was assembling products from components built in China, for export to Europe. Their inputs got new tariffs in 2025, and European retaliatory tariffs hit them on the other end. The jobs were moved to a factory in China.

tomjakubowski··on Where did all the public bathrooms go?
Fascinating stuff. And what a logo.

> Starting a national crusade to cast away coin-operated commodes, Gessel told newsmen, "You can have a fifty-dollar bill, but if you don't have a dime, that metal box is between you and relief."

I'm sympathetic to this argument. Carrying around loose change with US-style billfold wallets has never been convenient, and back in the day you'd often find yourself without change for a bus fare or a pay phone and so on in a critical moment.

Today, though, almost everyone carries either a contactless credit card or a phone with an NFC wallet. I would pay $0.25 for access to a clean public toilet if I could swipe one of those instead of having to carry change.

LA Metro has these restroom facilities at their rail stations, which are free for a 10 minute visit but require an access code on your phone or a standalone entry pass. I've never used one, but heard great things. https://thronelabs.co/

tomjakubowski··on Scrap
I would also think that unscrupulous scrap buyers would offer a lower price for copper which has obviously been stolen or stripped from public works, since they are taking on more risk by buying it.

tomjakubowski··on OpenRouter is joining Stripe
It isn't clear to me what advantages OpenRouter has over running a similar router-aggregator locally for ~free. I guess they have stronger bargaining power than a solo engineer or small startup, and can therefore negotiate volume discounts with model providers. The question is if those discounts let them offer cheaper rates than a local router-aggregator even after the markup. And if they can do that, then OpenRouter is undercutting the providers themselves on price, which I would imagine the providers would not want to see.
tomjakubowski··on Incident with Github.com
Strange. The back button in the UI is disabled once you get back to September 2016. https://www.githubstatus.com/uptime/8l4ygp009s5s?page=40

tomjakubowski··on A Preview of DuckDB v2.0
DuckDB is much like SQLite, but built for OLAP workloads: it's in-process, with a single file format on a disk, and (unlike SQLite) the data is stored in columns for better OLAP performance.

Like SQLite, concurrency options are limited compared to client-server databases like Postgres or MariaDB. DuckDB 2.0 will be adding a client-server mode with the Quack protocol which can allow for greater concurrency.

But you can also use DuckDB as a multitool to connect to and query all kinds of other data sources from one connection. Being able to pull in data from Postgres, CSVs or parquets on a file system or S3, and JSON returned by a web API, and then query across all of it in one place, can be quite handy for ad-hoc data analysis and exploration.

tomjakubowski··on Linear algebra done right
Strang's OCW lectures are fantastic. His voice rings "combinations of columns" in my head almost ten years later whenever I do a matrix or matrix-vector multiply on paper. I found the textbook was a good accompaniment for the lecture course, but maybe not a good book to use on its own for self-study. (IIRC, when following the lectures, you jump around the chapters a bit out of order [or, you read the chapters non-linearly]. So the disorganized thing may be true.)

Yeah, I think N_Lens was saying the manager's behavior in that anecdote was too high a bar.

Would be nice if they did support that, but on a LAN you can always encrypt at layer 3 with WireGuard.

There's an open source project which is a syslog daemon that stores logs in DuckDB. You can configure journald to forward logs to it.

tomjakubowski··on Thanks to social media, canned sardines are a scarcity on the supermarket shelf
Here in the US, on the regular retail side of Amazon, I see a twelve pack of 3.75oz canned sardines in water, Beach Cliff brand, for $18.96, or $0.42/oz. I don't buy sardines but this seems not terribly out of line with prices I see at Walmart and Target, maybe a 20-25% premium. A local fancy grocery store has sardines in water from Chicken of the Sea at $0.58/oz.
tomjakubowski··on Thanks to social media, canned sardines are a scarcity on the supermarket shelf
Shelf-stable foodstuffs like canned sardines can be ordered for delivery from the regular Amazon, the same side of their site you might order a book or a laptop from, outside of their newer grocery retail channels.

Genealogical software, historical video games (CK2 has at least one mod which adds alternative calendars), I can imagine there are some needs for this in contract management software for countries with very old businesses and properties like England and Japan.
tomjakubowski··on The Warp Agent CLI
Maybe I'm misunderstanding you, but it's not necessarily a terminal feature per se. Have you tried setting `vi` mode in your shell? There is a bit of lag going into normal mode in ghostty; maybe ghostty is configured by default to wait for a second keypress when you hit Esc and you can disable that.

tomjakubowski··on Getting 25 Gbps Thunderbolt Ethernet on My Mac Studio
Might their professionals market segment (designers, video editors, 3d artists, and so on) still be using thunderbolt and LAN storage? This was the case ~7 years ago when I worked adjacent to these sorts of users. Video files are huge and expensive in time and money to transit with cloud storage providers.
tomjakubowski··on Where .env Went Wrong
pydantic-settings is not limited to loading from config files. It is easy to populate a settings model from environment variables, for example. With a little bit of glue code it could load from the secretspec sdk.
tomjakubowski··on Dubious research tied to Red Bull has shaped energy drink policy
There is actually quite a lot of variation from person to person in caffeine elimination half-life, from about 1.5-9 hours. Some of my extended family could drink a cup of coffee right before bed without issue.

tomjakubowski··on Dubious research tied to Red Bull has shaped energy drink policy
Drip coffee has ~40-50% more caffeine per 8oz serving than Red Bull (about 90-100mg vs 65mg). The nice thing about coffee is that the mouth-puckering tannins make it harder to absolutely pound them, like one can do easily with cans of Red Bull.
