Taming Undefined Behavior in LLVM
Interesting post, but you lost me at “Let’s try to do that using undef”. Why bother with notions of an “undef value” (or “deferred UB”), when plain UB is all you need?

Undefined Behavior != Unsafe Programming
Are you arguing that undefined behaviour should not be a thing in, e.g., C? It sounds like you’re claiming that the fabled sufficiently smart compiler could take code in a C-like language with no UB, and emit something equivalent to what a C compiler would produce given equivalent input in C that correctly avoids UB…

Counting Clojure Code
For better or worse, we count lines of code. We (hopefully) feel a little dirty when we do it, because it's a flawed metric. But we do it . We do it on large codebases and small code snippets . Even badass hacker David Nolen does it .

That project used Smalltalk, and team contribution was provided by Object Technology International’s ENVY version control system. I wanted to know more about that so I…

Dictionary and Set Improvements in Swift 4.0
In the latest release of Swift, dictionaries and sets gain a number of new methods and initializers that make common tasks easier than ever. Operations like grouping, filtering, and transforming values can now be performed in a single step, letting you write more expressive and efficient code.

Go and Simplicity Debt
Fifteen years ago Python’s GIL wasn’t a big issue. Concurrency was something dismissed as probably unnecessary. What people really was needed was a faster interpreter, after all, who had more than one CPU? But, slowly, as the requirement for concurrency increased, the problems with the GIL increased.

Here are some of the many meanings of "think": "ponder; reflect (on); believe; consider; cogitate; feel; deem; hold; suppose; imagine; remember; recall; conceive; deliberate; recollect; evoke", etc. Thomas J. Watson , who led IBM from 1914 to 1956, first…

Manipulate Functions with the J Language
The Pragmatic Programmer recommends that we learn at least one new language every year. To be effective, the languages we learn should differ sufficiently from those we already master and ideally introduce us to a new paradigm too. Learning a different programming language affects the way we view code. A new paradigm…
