I managed to get some decent results using this algorithm (not at my own computer so can't post code, yet): - create a smaller greyscale copy of the image, and use sobel to calculate gradients (smaller to speed this up) - set a gradien

While this is nice enough, it bothers me that these don't look much like "art". If you look at real roman mosaics, they do not place points in a grid - they use a technique called "opus vermiculatum" https:/&#

This is frustratingly difficult to understand from the site because they never include a human in the photos for scale (though the text says it's 3m in diameter). This video is a bit better https://www.youtube.com/watch

Back in... 2006ish? I got annoyed with being unable to copy text from multicolumn scientific papers on my iRex (an early ereader that was somewhat hackable) so dug a bit into why that was. Under the hood, the pdf reader used poppler, so I m

it's a bit odd at the end referring to "a German high school teacher and amateur decipherer who, in 1802, looked at Aramaic-related inscriptions..." without naming him like everyone else mentioned - that is Georg Friedrich Gr

I got better results just dithering the rgb channels separately (so effectively an 8 colour palette, black, white, rgb, yellow, cyan, magenta). In p5js: var img var pixel var threshold var error = [0, 0, 0] var a0

I made a terminal based presentation tool some years back and like sibling comments said, it was neat for switching back and forth to code samples and output. Mine wasn't markdown tho: I used ttyrec to record a terminal session to a fi

The comment about world events not being what matter in our lives is accurate (world events don't generally happen to us personally-fortunately) but it got me thinking, it might be nice to see some of these done for historical figures,

Not animated or svg, but along the same lines, some years ago I wrote https://bazzargh.github.io/stripmap/ which automates generating stripmaps. The idea was to eventually use this for travelogues of my cycling trips;

Is that not very dead? I remember trying to order some gifpop stuff back in 2021/22 and they were gone by then. I see the "make your own" page on the site is broken, the blog entries are from 2017 (hover over the bottom of ea

A fun one like that, a few years back we had some code using dynamodb that used the automatic point-in-time backups. I asked if it had been tested, need you guess the reply? Of course it turns out that the restore can only happen to a _new

A common thing in JSON/YAML alternatives is to support more types through syntax. I don't think this is a good idea. YAML already did this badly with the Norway problem, but JSON also has issues with eg "is it float or int&qu

I do sympathise somewhat with that view, but I disagree. To be valid in as many browsers as possible, and as many back-end systems too, serialize() would have to take the _narrowest_ view of the spec possible. If you make cookies that stray
