What a wonderful piece of software! I'm glad to see that there are people who actually remember to use computers for the purpose of computation - and help others do so as well!

just started to use Chalk and am fascinated by the choices you've made. However, the UI is very small on my large monitor. Is there any way you could add an option to scale the UI and output? I'd love to be able to double up the size of the UI. Many apps use cmd and -/+ to scale the window. I'm on a 4K monitor and virtually every other app I use scales to use the High-DPI output option. Thanks!

It takes a great deal of patient thought to make something simple and usable. I am a happy user.

Many years ago, as a student, I first learned about interval arithmetic, accuracy, and representation from the work of Bill Walster at Sun (before it got eaten by Oracle).

Your article explaining the shortcoming of modern calculators and your careful design of Chalk, reminded me of this. Merci beaucoup, not only for beautiful software, but also beautiful thoughts!
