mjd··on The Lottery – Shirley Jackson (1948)
“She Faced a Life-Threatening Miscarriage. Under Arkansas’ Abortion Ban, Even Calls to the Governor’s Office Didn’t Help.”

That's from this morning, reported in ProPublica.

mjd··on The Lottery – Shirley Jackson (1948)
Hit-and-run vehicle collisions.

Innocent bystanders of gang violence.

Factory workers killed by industrial machinery.

That chemical tank in Los Angeles that is about to explode.

Woman in Arkansas with ectopic pregnancy. (Abortion is illegal in Arkansas.)

Now you think of one.

This sort of theoretical result is not always as clear-cut as you suggest.

Computers are finite machines. There is a theorem that although a machine with finite memory can add, multiplication requires unbounded memory. Somehow we muddle along and use computers for multiplication anyway.

More to your point there is a whole field of people who write useful programs using languages in which every program must be accompanied by a proof that it halts on all inputs.

(See for example https://lean-lang.org/ or David Turner's work on Total Functional Programming from about 20 years ago.)

Other examples are easy to find. The simplex algorithm for linear optimization requires exponential time in general, and the problem it solves is NP-hard, but in practice works well on problems of interest and is widely used. Or consider the dynamic programming algorithms for problems like subset-sum.

Theory is important, but engineering is also important.

mjd··on US will start revoking passports for parents who owe child support
I accidentally read the comments on the post and got as far as this one:

“Honestly, since we're going towards socialism, we need to abolish child support. Women have the right to get an abortion because it is their body their choice. A man has to use his body …”

That was enough for me.

mjd··on Feds Fine Durham Energy Efficiency Co $722M
Matt Levine's introduction to this story made me laugh:

“If you have a certain sort of mind, you might think ‘no, people respond to incentives; if the grid paid for every efficient lightbulb, we’d save more electricity.’ If you have a certain, not unrelated, sort of mind, you might think ‘well, if nobody is getting paid for installing these lightbulbs, maybe I should get the money.’”

mjd··on Ask HN: Is the Job Market Actually Bad?
The employee's goal here isn't to make the employer feel proud, it's to exchange their services for money.

If the employer wants an employee they can feel proud of, well, that's a service too, and one they can purchase with money, if they choose.

mjd··on It's OK to abandon your side-project (2024)
Abandoned doesn't have to be forever. As I got older I had a longer time horizon and more skill, and found I was picking up and finishing projects I'd laid aside decades earlier.

Now when I put something aside I know there's a chance I might pick it up again in ten years. There wasn't much evidence of that when I was twenty-five.

It's been one of the best things for me about middle age.

mjd··on At least 10 people tied to sensitive US research have died or disappeared
I wonder if it is reasoning. To me the sequence looks something like this:

1. The story is promulgated by a long-retired ex-FBI analyst

2. Fox News picks it up and runs with it

3. Fox News watchers get excited about it on social media

4. Someone behind a desk at the FBI is assigned to pick up the phone and say tiredly “Yes, yes, we're investigating it all very seriously”

5.The FBI waits for the new Flavor of the Week to distract the Fox News people, then closes the investigation

Meantime, CNN reports on phase 4.

mjd··on At least 10 people tied to sensitive US research have died or disappeared
It's worse than that, it's 11 people who wore sweaters in various shades of red, orange, and pink, at some point in the past ten years.

“Anthony Chavez, 79, worked at Los Alamos National Laboratory until he retired in 2017. He reportedly disappeared on May 8, 2025.”

mjd··on At least 10 people tied to sensitive US research have died or disappeared
Last time I looked into this (last week, I think) it was a big wad of nothing. The people had disappeared over a span of many years. They weren't tied to any particular program, employer, or even any particular area of study, just “uh, tech stuff”. Some of them were technical experts, some weren't; one was an administrative assistant. One was killed by a campus shooter who also killed two students.

Typical example: “In the years since, several others connected to JPL have also died or disappeared: Frank Maiwald, a specialist in space research, died in Los Angeles in 2024 at 61.”

mjd··on John Bradley, author of xv, has died
XV was excellent, and had some features I've never seen anywhere else. For example, it had a control panel that would allow you to take part of the color space and map it uniformly to a different part of the color space, for example, turning all the reds (and just the reds) green.

When my kid, now almost 22, was very small, she would sit on my lap in front of the computer, with XV displaying a picture of Elmo. “Green Elmo!” she would demand. I would adjust the sliders to turn the reds green, and we would laugh uproariously at green Elmo. Next it would be “Purple Elmo!”, and we would laugh even harder.

This kept us both amused for quite a while.

(Update: Here's a picture of what that control panel looked like. The turn-Elmo-green control is top center. https://xv.trilon.com/manual/xv-3.10a/color-editor-1.html)

mjd··on White-collar AI apocalypse narrative is just another bullshit
In companies I've worked for, Sales has often come to management saying things like:

* I couldn't sell our product because our competitor's has a certain feature. How soon can we have that feature? * I can't make any new sales, but prospective customers keep telling me they need a solution for a similar problem. Could we expanded our product line? * Some customers could be using a certain feature of our product, but they find it too confusing. What could we do about this? * A big customer told me they have a problem our current product doesn't solve, so I told them we would be able to solve it by the beginning of next month

As you say, the sales department is the driver of development work, not vice versa.

mjd··on White-collar AI apocalypse narrative is just another bullshit
Every company I have ever worked for has wanted to produce more better stuff to sell for more money. Some couldn't because they were resource constrained.

Where are these businesses that only ever want to sell the same amount of the same stuff forever?

mjd··on White-collar AI apocalypse narrative is just another bullshit
Or it might mean they produce more valuable product and more of it and therefore need more devs to do it.

If a dev produces value for the company, and then the company can automate away the least valuable part of the dev's job, the dev is now more valuable. Why would tbe company get rid of them just at that moment?

Well, some will, because some companies are badly-run. Others will take advantage of the opportunity.
