Plurrrr

In the first entry in this series, I argued that "what is a monad?" is not a useful question for the working programmer. In the rest of the series so far, I have explained how to recognize situations in which a monad could be useful, how to apply monads, and how to create bespoke ones.

But I still have not really defined what a monad is, and, while I stand by the argument that the answer is not useful, I can imagine that not having the answer may be a bit frustrating. In this post, I'll try to explain what a monad is, as best I can.

One of the new OpenZFS features that became available with FreeBSD 12.0 is ZFS Channel Programs. Today’s article answers some common questions regarding ZFS Channel Programs and provides some resources for learning how to create your own Channel Programs.

Data races — the worst nightmare of all developers! They are hard to detect, very unpredictable, and extremely difficult to fix. Apple has given developers various toolsets such as NSLock and serial queues to prevent data races from happening during runtime, however, none of them are capable of catching race conditions during compile-time. With the release of Swift 5.5, this will no longer be the case!

Introducing Actor, the new Swift language feature that can help developers to catch any possible race conditions during development time. In this article, we will first look at how a data race occurs when using dispatch queues and asynchronous tasks. After that, we will look at how actors can help us to identify race conditions in our code and prevent them from happening once and for all!
