Analyzing cryptographic systems usage with respect to how the users interact with it sometimes requires programmatically simulating their actions. It is no different with our recent work on rclone cryptographic keys handling. However we are lucky that Racket provides all the functionality we needed!

As we have already revealed, we use Punct to produce our new website. Punct is extending CommonMark with metadata and uses Racket racket-commonmark. Sometimes there are problems with software, but usually those can be solved - as happened in this case. And with a new release, new features arrived as well.

In 2016 we decided to implement our website in WordPress which was deemed adequate at that time. However the times are a-changing and now we have migrated to our custom publishing pipeline using Racket and Punct.

As I have written before, Racket is used for implementing most of our tooling and helper applications both for the Cryptoucan™ development and for other back-end tasks as well. You can rightfully guess that most of the bookkeeping programs need to access various databases and although accessing databases is super-convenient in Racket, with some databases on weird platforms, strange problems may arise. Read on to see one of the more interesting and also to see how to resolve such issues.

As you might recall, Racket provides no way of working with bitmap data both ways: writing and reading. There are only methods that can help you directly access bitmap  ARGB data and those are not designed for any high performance tasks. Read on to learn some new tricks to access the bitmap data faster...
