Tips for tpp and patat

By

You might be surprised to learn that there are programs for running presentations in a terminal. No, I don't mean opening PowerPoint or Impress slides one after the other, as images in a frame-buffered console. I mean presenting slides coded for the terminal, in a terminal. Interesting idea? It…

The joys of ISOdates

By

It took me a fair while to get comfortable with the ISO 8601 date format. After so many years of using DD MMM YYYY, my old eyes and brain had some trouble understanding YYYY-MM-DD. Finally something clicked, and I now read 'ISOdates' easily and I really appreciate their advantages. The biggest…
