We’re in the longest @BCiechanowski drought this decade. https://t.co/c0Mv50lqpb
Bar chart titled “Days Between Bartosz Ciechanowski Posts,” showing the number of days between each article on ciechanow.ski. Most gaps are under 200 days, but there is one very large gap of 1,693 days between “Mesh Transforms” and “Exposing Floating Point.” Later gaps include 336 days before “Airfoil” and 294 days before “Moon.” A separated, hatched final bar shows that it has been 628 days since “Moon.”

One of my favourite things about social media is replying to something completely unrelated to tech and finding someone else, who followed me for tech, who is also into the other thing. 4.2K views · 33 likes · 0 reposts · 7 replies Open on X →

A screenshot from my reservoir sampling post. In it you can see a visual of cards being shuffled at the top, and underneath that is a bar chart tracking which cards appear early in the shuffle.
A screenshot from my Big O post. In it can be seen a bubble sort algorithm written in JavaScript. Above the code is a visual of a 5-element array being bubble sorted.
A screenshot from my prompt caching post. In it can be seen a visual of 8 clusters of coloured points shown in a 3-dimensional graph.

A screenshot from my Bloom Filters blog post, showing a visualisation of the bits inside a bloom filter after the words "loved" and "your" have been added. There is also a code sample visible that reads: let bf = new CountingBloomFilter(); bf.add("loved"); bf.add("your"); bf.remove("response"); bf.contains("loved"); // false
A screenshot from my Queueing blog post. A list of goals can be seen that says: - Add 15 requests to each queue. - Add 10 priority requests to each queue. - Drop 15 requests. - Drop 10 priority requests. Below this task list can be seen a visualisation of 4 different queues.
A screenshot of my Turing Machines blog post. A Turing Machine running the first program seen in Alan Turing's 1936 paper can be seen, it prints alternative 0s and 1s to the tape.
