Lua: Good, Bad, and Ugly Parts (2012)
I have been programming in Lua for about 9 months and it seemed like a good time to pause and reflect on my experience with it. I have used various languages over the years -- Perl ( soaplite.com and other projects, including my current consulting work), C ( a DHCP /DNS server for Arduino and a ping-pong juggling…

New Elixir 1.12 – The developer’s point of view
The Elixir 1.12 version introduced some significant changes. The main one is the ability to create scripts and import dependencies via Mix.install. The interactive console can be more helpful in the software development, prototyping and debugging processes.

Java's records, Lombok's data, and Kotlin's data classes
While all three remove boilerplate, the similarities don't go much further. Records have stronger semantics with important downstream benefits, which makes them better*. (* not always; depends on circumstances; excuse the clickbait)

From Julia to Rust
I've been more serious about learning Rust recently, after dragging on with passive learning for a while. My first real programming language was Julia, and I know other Julians interested in Rust. I've written this article for those people in mind, because Rust and Julia are good performance sparring partners, but…

Lessons learned after working one year as a Common Lisp Developer (2018)
I intented this to be a small post with some lessons learned after working one year as a CL dev, however it turned out quite long (two parts!). As always: All opinions are my own. This post is not endorsed by anybody.

Generics facilitators in Go
Go 1.18 is going to be released with generics support . Adding generics to Go was a multi-year effort and was a difficult one. Go type system is not a traditional type system and it was not possible just to bring an existing generics implementation from other language and be done. The current proposal was accepted…

Kina Knowledge, using Common Lisp extensively in their document processing stack
Recently, the awesome-lisp-companies list was posted on HN, more people got to know it (look, this list is fan-cooked and we add companies when we learn about one, often by chance, don’t assume it’s anything “official” or exhaustive), and Alex Nygren informed us that his company Kina Knowledge…

Fitting a FORTH in 512 bytes
Software is full of circular dependencies if you look deep enough. Compilers written in the language they compile are the most obvious example, but not the only one. To compile a kernel, you need a running kernel. Linkers, build systems, shells. Even text editors, if you want to write the code instead of just…

Let's write a compiler, part 1: Introduction, selecting a language, and planning
I think we all knew this might be coming once we finished up with our assembler . While we can in theory solve any computable problem by writing the appropriate assembly for our assembler, writing assembly code can be a bit more cumbersome than a high-level language. There is a reason why we did not write our…

My tutorial and take on C++20 coroutines
Over the last 25 years, I’ve written a lot of event-driven code in C++. A typical example of event-driven code is registering a callback that gets invoked every time a socket has data to be read. Once you have read an entire message, possibly after many invocations, you parse the message and invoke another callback…
