For a language that claims to focus on one right way to handle most situations, string formatting in Python is quite a buffet and it’s getting more diverse by the year. Starting with Python 3.6 we now have three ways to format strings (outside of simple concatinating things or using string.Template ):

The first half introduces Rust’s language features and libraries for error handling. The second half should help you write good error handling code in Rust.
A selection of the details that makes Clojure such an enjoyable language to work with.
I’ve been learning Rust for the past twenty days or so, working through the Blandy & Orendorff book, coding up things as I go. Once I got into playing with Rust traits and closures and as…
A dive into the unknown personal and academic history of the mathematician who developed combinators, Moses Schönfinkel.
Hello, friends! Long time no blog!I'm still here hacking away on JRuby for the benefit of Rubyists everywhere, usually slogging through compatibility fixes and new Ruby features. However with the release of JRuby 9.2, we've caught up to Ruby 2.5 (the current release) and I'm spending a little time on performance.I…
As we approach the final release date for Python 3.13, I’ve seen an uptick in discussion regarding 3.13’s introduction of an optional GIL. While removing the GIL has been a long time coming for the average user (I’ve dreamt of this for nearly 20 years), there have actually been two concurrent efforts to improve…
within Rust is a smaller language struggling to get out
A discussion of some of the downsides of Zig
So, this is a little case study. I did everything for Dylan. And when I say everything, I mean everything . Here's my resumé: I got e...
Oh, and - added later - the original from PG is undated, but the "enhanced" version below it was on the C2 wiki in 2003/2004 and possibly earlier, so don't for one minute think it's supposed to be up-to-date, or refer to modern version of these languages.
Lisp lets programs define new setf forms for assignment. The most common example is from CLOS , where a class like this:
Look at a tiny syntax detail that shows up in current versions of rust that has profound implications on how the language deals with almost everything being an expression.
Reimplementing Haskell lazy infinite lists using Python generators
Over the years I’ve found myself with a weird amount of knowledge about how types and ABIs in Rust work, and I wanted to write it all down in one place so that… it’s written down in one place. Much of this information can or should be found in the Rust Language Reference and the Rustonomicon .
Why are macros in Haskell terrible, but macros in Racket great? There are certainly many small problems with GHC’s Template Haskell support, but I would say that there is one fundamental design point which Racket got right and Haskell got wrong: Template Haskell does not sufficiently distinguish between compile-time…
Currently the most common implementation of Python is known as CPython, and it’s the version of Python you get at python.org , probably 99.9% of Python developers are using it. However, I think over the next couple of years we’re going to see a move away from this towards PyPy, Python written in Python. This is going…
Any problem in computer science can be solved with another level of indirection. Except for the problem of too many layers of indirection.

Handling errors in Go is simple and flexible – yet no structure! It’s supposed to be simple, right? Just return an error , wrapped with a message, and move on. Well, that simplicity quickly turns into chaotic as our codebase grows with more packages, more developers, and more “quick fixes” that stay there forever…
