Chapter 24 & Chapter 28 (Concurrent and parallel programming & STM)
While Chapter 24. Concurrent and multicore programming and Chapter 28. Software transactional memory are still relevant, Simon Marlow's book Parallel and Concurrent Programming in Haskell focuses solely on concurrent an...
Why exactly is eval evil?
...oated instead.) There are good alternatives to lock-based threading, like STM or actor models, that makes the use of it in anything but the lowest-level code evil.

Common programming mistakes for Clojure developers to avoid [closed]
... do it, but only the object reference in the ref itself is governed by the STM - not the referred object and its fields (unless they are immutable and point to other refs). So whenever possible, prefer to only immutable objects in refs. Same thing goes for atoms.

EDIT to add: Pugh's lock-based skip list, which was benchmarked in Fraser and Harris (2007) "Concurrent Programming Without Lock" as coming close to their own lock-free version (a point amply insiste...
Scala vs. Groovy vs. Clojure [closed]
...anguage in the LISP family, it's also dynamically typed.
Features such as STM support give it some of the best out-of-the-box concurrency support, whereas Scala requires a 3rd-party library such as Akka to duplicate this.
Syntactically, it's also the furthest of the three languages from typical Ja...
How can a time function exist in functional programming?
...d. Another context is within an atomic transaction, for which we have the STM monad. Yet another context is in the implementation of a procedural algorithm (e.g. Knuth shuffle) as a pure function, for which we have the ST monad. And you can define your own monads too. Monads are a kind of overlo...
