J-Fall 2023: Modernize your money-maker – Tim te Beek

Most every company has that one product. The project that’s consistently brought in revenue over many years. But it’s also the one that shows its age, and might not be enjoyable to work with.

J-Fall 2023: ASCII to Unicode, what can possibly go w̵̳̓r̸̡̽ǒ̴̝n̴̬ͣg̶ͤ͜? – Adam Michalik

What is a character? What does “the length of a string” mean? How can I combine different scripts in one text? In the days of ASCII, the answers to these questions were plain and simple.
