In a previous post we wrote about the challenges of implementing DAG scoping model for bindings in certain Qi forms. Today we are about to witness an attempt to bring similar scoping rules to plain Scheme and we may reason a bit whether it could be useful in practice.

Qi is an interesting, flow-oriented programming language. It has a very tacit vibe. But still - sometimes it is useful to bind values to named identifiers. And with certain flow forms you end up with strange binding scopes.

Today we are bringing some unifying good news for all Racket and Chez Scheme folks having to run their applications on that alternative operating system called Windows. With Racket 8.17 released, it is possible to fully suport even mouse input in terminal applications on that strange platform!

During the years, there were many cryptography-related articles published on our blog. Many of those contain mathematical formulae using LaTeX notation. The time has come to render those again and one JavaScript package turned out to be just the right ingredient we needed.

Last week on January 24th, version 5 of Qi was released. This release contains support for flows in higher-order argument positions and in sequences of qi/list procedures a faster runtime code is produced by the compiler.
