A fresh sourdough baguette, butter, brunost, and a cup of coffee. Sooo yummy, I can't focus on editing the manuscript.

TIL: "Let me know if the test fails" asks for a message only in the failure case. "Let me know whether the test fails" asks for a message either way. #English #writing

The office worker in me, starts to feel countercultural in a conservative sense. A serious company wants to get in touch with me regarding research collaboration. Instead of sending an email or calling, a high profile VP, befriends me on linked in and sends me chat messages on a channel that I […]

I'm so old, I remember when software that spread into the wild and infiltrated other people's computers and did harmful things to them that the users didn't ask it to was called "malware" instead of "AI" and the people that spread it were prosecuted instead of given billions in venture capital […]

Chirstian Kästner (whom I don't think is here) has written a clear post about externalizing the cognitive cost of using AI on others. It is clear, not AI-written, and reflects also very much what I think. Preparing a bad AI-generated text costed you no time. Processing it takes my real […]

The probabilistic programming library #Probula in #Scala, got a new minor release today (v.0.2.3). The release includes a bunch of small improvements that slowly make probula usable: (support for vectorized variables/plates, for-comprehensions, truncated […] [Original post on social.dukla.ch]

Well-trained and experienced software developers still highly relevant in the age of AI! It took me six days to fix a subtle but critical bug. The issue's and fix's complexity make me think AI couldn't possibly handle it. If you want to prove otherwise though your agentic prompting skills […]

I am reading a bit of, a bit about, Marcel Proust. And I am having my Proust moment. I suddenly remember a scene in Paris, earlier this year, in a random café, I stopped for breakfast, they have run out of croissants. I order coffee solo. A few minutes later the waitress comes, I must have […]

For whatever reason, I simply haven't been on the shore all that much, this summer. A trip to our old favourite, Cockenzie in East Lothian, was called for. ...And an #AmperSand was thusly delivered. It's been too long. More here in the archive, if you're new […] [Original post on mastodon.scot]

You can see the approaching edge of the rising tide only a meter or two away, now, in the sheltered village cove.

A shadow is cast over the ampersand by the legs of the photographer, who's standing just next to it. His feet don't make the lettering any more beautiful, but they provide a sense of scale!

Did you know that 3D printed covers for Flock cameras are easily printed and make cameras inoperable when you plop them on using a pole? I share this information for no reason at all.

Hvis jeg så hele tiden har en undervisningstime på vej, så får jeg reelt aldrig mere end en dag af gangen. Dermed står det hele de facto næsten stille. Jeg kan på en måde næsten lige så godt rydde op i et skur.

I felt very lazy working on a grant proposal, so in the spirit of structured procrastination, I have processed and written up my meticulous notes on what to do, once you move your academic website to a new location. A long list of redirects! I hope that some who are also in this situation can […]

A small step for the humankind, a huge celebration for my inner nerd. The most beautiful formulation of Fisher's 1922 dilution assay model in the history of humankind has landed 😊. A lot has been happening in Probula lately, but chiefly I worked on syntax to […] [Original post on social.dukla.ch]
A piece of Scala code (Probula, an internal DSL) encoding Fisher's model, a screenshot from a neovim editor buffer.  The code is as follows:

```scala
import math.log
val data = FisherPlated.dataK

val posterior =
for ρ  <- UniformC(0, 2000)                            // prior
    η  =  (1 to K).map { i => log(ρ) - i*log(2) }      // linear predictor
    πs =  η.map { Cloglog.inverse }                    // (inverse) link cloglog^-1
    _  <- πs.plateD { Binomial(N, _) }.observing(data) // likelihood+data
yield ρ

// Importance sampling inference
val stats = posterior.sample(1000.sampleSize).precis()
```
