    People say that it's a practice. A few years ago I was determined to practice, and it was hard, and then it became easy, auto-relaxing, like a cheat. I lost that practice and now i…

    Thanks for the prompt! I made a new gallery that's mobile friendly and I almost forgot why I need to land it - adding it to the list!

    If you need to know a leap year and it's before the year 6000, I made an interactive calculator and visualization [1]. It's >3 machine instructions (and I admire the mathematical t…

    This is a cool way to teach! I was blown away by the little functions at first and I too made a clone to experiment with calculang [1]. I added an evaluation feature (F9) so you ca…

    Neat UI, are you using a library for that?

    Really pretty outputs! And impressive that the code is shown so elegantly and also interactive. This algorithm is one I use to demo some features in a language I'm making called ca…

    Post-retirement is definitely harder. There are also usually rules about what's allowable with the money that built up with tax relief and such. Since these rules differ from count…

    Author here - Health warning third bullet point is: > Even when there is tax relief to save for a pension, this doesn’t mean that there aren’t taxes on pension income after retirem…

    Hi - author here - these compound returns are not guaranteed. I reinforce this point under health warnings. Here the 6% compound returns is an assumption. If that's good or bad to …

    Author here - This blog post is a 'narrative visualization' to show some nice savings incentives visualized in a chart. I think these are important to have a good understanding abo…

    43,333 homes using 13Bn and 300k cost; I guess you changed one of these or did something else ?

    To get my editor component and compiler interacting with that reactive system it got a little messy, and I'll review and hopefully fix it before I push this to a wider calculang pl…

    In this example it might not be so practical, but in calculang everything is a function including constants. This is because of an emphasis on flexibility. They're a constant here …

    I use reactive Javascript which shows errors until a few pieces click together (best that I can understand it atm). So it's normal to have a string of errors and then everything wo…

    Thanks for checking it out and for the comment! This surprised me, but you are right. The only thing I can point to referring to this example only is that there is a lot of Javascr…

    Show HN: 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 b…

    Hi! I made this scroll-based interaction to Visualize risk. The coordinated visuals are using Vega-Lite. The calculations are from composing calculang models: one which simulates r…
