Hi, I made this page to contextualize 13 billion euros (or 14): an amount due to Ireland in an EU Apple tax case and all over the airwaves here this week. I use some pretty silly back-of-the-envelope type calculations (the same ones also repeated a lot in Ireland this week!). These calculations aren't especially interesting, but at least they are present: you can see them, and you can change them. If you do - change the 13 billion to 14 billion for example, related numbers will flash with updates. It's an example using calculang[1]: a language for calculations, and an example that focuses on…

Hi HN, I built Own or Rent (https://ownorent.com) after getting frustrated with existing rent vs. buy calculators that hide assumptions and use confusing jargon.

Most retirement calculators either oversimplify things or ask you to link your accounts so they can make money off your data. I wanted something that actually helped me see if I was on track without handing over a bank login, so I built RetireNumber. It's a privacy-first retirement planner. You type in your own numbers. No account linking, no selling your data, no VC. Just me and a subscription. The engine does real math: Monte Carlo with 1,000 runs, historical backtesting to 1928 using Shiller's Yale data, tax-aware withdrawal strategies, and scenario comparison so you can try different…

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!
