The previous post looked at how to interpret cosine similarity, or equivalently angles between word vectors. In a high-dimensional space, randomly chosen vectors are likely nearly perpendicular, and so relatively large angles, such as 50°, indicate very closely related words. Another way to look at this, as explained in the previous post, is that in […]

Since people keep asking how this blog is made, and I don’t want to share the awful, terrible code that it is taped together with, I’ve decided to start explaining parts of it piecewise. Generally, any time something breaks and I have to fix it, I write down what I di...

Machine learning represents words as vectors and measures the similarity of words by the angles between the vectors. For vectors x and y, where θ is the angle between the vectors, and so This is the cosine similarity between the words represented by x and y. Small angles have large cosines, and so words with larger cosine similarities […]

On September 15, 1998, Diamond Multimedia introduced an MP3 player, the Diamond Rio PMP300. It wasn’t the first MP3 player, but it made the MP3 player mainstream. I had one. It wasn’t exactly great, but I understand why the RIAA

Early AI agents were basically enthusiastic idiots. Working with them required you to tell them precisely what you wanted them to do (for instance, “method A exists on class B, please add an equivalent method to classes C through F”). Otherwise they’d go off and do entirely ...

A new tool for digging into Usenet history holds much potential for researchers. But it’s also a reminder that many users thought, at the time, that it was ephemeral. (They were wrong.)

The contagion of fear Bryan Cantrill responds to the tweet by former Anthropic employee Jacob Coxon confirming that many Anthropic researchers believe AI "could kill us all by the end of the decade". Bryan shares a story of his own youthful mistakes causing unjustified panic...

Yesterday David Sacks wrote a tweet and within a few minutes people did, what they usually do, and they asked Pangram if it was AI. And Pangram said it’s entirely AI generated. To which David replied that these AI detectors are bogus. Now Pangram has a pretty low false posit...

September 24, if played right, could change everything

The cost of writing code collapsed, and the cost of reviewing, fixing and operating it is following, and I'm assuming it gets there. What's left of making software is finding out what people actually want, defining it precisely, and making it pleasant to use. That cost is per piece of software and doesn't transfer, so as the amount of software goes to infinity, which it will because there's no ceiling on demand, that cost becomes the whole job.

De korte versie: De Nederlandse overheid “is niet (echt) van de IT”, en legt vrijwel altijd haar oor direct of indirect te luisteren bij een door big-tech gedomineerd ecosysteem om te bepalen wat te doen. En daardoor valt de keuze vrijwel altijd weer op Amerikaanse platformen, gerund door derden, onder Amerikaans (afluister)recht. En tegenwoordig ook vol met AI (of je nou wilt of niet).
Om weer grip op IT te krijgen, en een eigen en autonomer pad te kiezen, moet er een hoop veranderen.

The HTML specification is old and, while there is beauty in longevity, there's an inevitable build-up of boondoggles and baggage. Some elements like <marquee> have sadly been consigned to the dustbin of history - but there are still vestigial attributes just waiting to trip up the unwary. If you're young, you may never have heard of Image Maps. Back in the bad-old-days, there weren't many good…
