How much is 13B euros?
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…

Various back-of-the-envelope calculations
But for other context , this is of Ireland's total expenditure in 2023 , and of Ireland's national debt. These back-of-the-envelope calculations are made using calculang : a language for calculations for structure, flexibility and communication about numbers. You can check (and change!) their formulas under the tab for '💬' (top left) "Scrubbable numbers" as an interaction technique for models - inside narrative text, is something championed by Bret Victor . I recommend his other work: especially the Model-driven debate section of his climate essay , to find further neat interactions with models and their calculations. This was a little, hurried exercise by Declan . Please don't use these…from howmuchis13billioneuros.com

Multilingual Salary Calculator for Germany2022 · lohntastik.de · ▲12Many people from a migrant background have difficulty understanding the German income tax system. Therefore, as a side project, I have created a multilingual gross-net-salary calculator for Germany. With this side project, my main goals are: 1. to create an intuitive method for non-German speakers to easily understand how and what is deducted from their gross salary in Germany, 2. to translate the calculator into Eastern and Central European languages (as they represent one of the largest groups of migrant workers in Germany) to make it easier for them to understand the German income tax…
Quantifying opportunity cost with a deliberately "simple" web appFeb 2026 · shouldhavebought.com · ▲28Hi HN, A while ago I had a mildly depressing realization. Back in 2010, I had around $60k. Like a "responsible" person, I used it as a down payment on an apartment. Recently, out of curiosity, I calculated what would have happened if I had instead put that money into NVIDIA stock. I should probably add some context. For over 10 years I've worked as a developer on trading platforms and financial infrastructure. I made a rule for myself - never trade on the market. In 2015, when Bitcoin traded about 300 usd, my brother and I were talking about whether it was a bubble. He made a bold claim that…
