Using the right tool for the right job
I've been porting the AndroidX collection library to Kotlin multiplatform to experiment with binary compatibility, performance, tooling, and the different memory models. Some of the data structures in the library use array-based binary trees to store elements. The Java code has a lot of shifts to replace power-of-two…
Code can really be written with any text editor that you're comfortable with. I tend to use Vim for quick edits and writing notes, and on L...
Picture this, the year is 1996. You find yourself frustrated with the incumbent search engines like AltaVista, which primarily does a content-based search (it'll give you an article on "Hotels for Chickens" if you search "Hotels" because the word matches).
