2025 = sum(I^3) for I = 0..9

This year's number is kinda fun: 2025 = 0^3 + 1^3 + 2^3 + 3^3 + 4^3 + 5^3 + 6^3 + 7^3 + 8^3 + 9^3 Which is equivalent to: 2025 = (0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9) ^ 2 = 45 ^ 2 Next time this will happen is 1000 years from now, in 3025. See y'all then!

In plain words

This is a mathematical observation about the year 2025, highlighting that it equals the sum of cubes of all single digits from zero to nine, which also equals 45 squared. The fact is presented as a curiosity for anyone interested in number theory or mathematical coincidences. The next year with this same property will not occur for another thousand years, in 3025.

    It's a a long puzzle, somewhat akin to a 2000 piece jigsaw puzzle. Solving it collectively with others is encouraged. If you are the sort that likes rules, the rules are you can use Google or whatever external sources you like for help. View page source, however, is cheating. Hat tip to Octagon and the TND crew for help in play testing and proposing categories.

    I made a calculator that works over disjoint sets of intervalsApr 2026 · victorpoughon.github.io · ▲314

    I've been studying interval arithmetic for the past few weeks and it's a really interesting field because while there is a ton of super interesting research published over the past decades, it has never really gotten the recognition that it deserves, IMO. One reason for this is that standard interval arithmetic has really poor handling of division by intervals containing zero. If you compute 1 / [-1, 2] in regular interval arithmetic, you get either [-∞, +∞], or you have to say that the operation is undefined. Both solutions are virtually useless. The real answer of course is [-∞, -1] U…

    Tetris in a PDF▲1,289

    I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…

    I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!
