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)
Programming, Coffee and Indie Hacking
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…
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.
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…
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…
Parser generators vs. handwritten parsers: surveying major language implementations in 2021
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…
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…
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…
Why not the programming language I'm already using or some other language? What makes Clojure uniquely well-suited for modern software development? Instead of…

Learn about type level programming by building a custom theming engine.
An unusual benchmark for programming languages, designed to replace C. Unlike many other benchmarks, this one measures developer productivity and performance.
Thousands of cam girls live right now from Colombia, the US, Europe and Asia. Watch free with no signup, and see when each model is usually online.
Edit 2021-03-30: Jeremy Mikkola wrote about some closely related topics back in 2017. Edit 2021-03-31: Chris Siebenmann wrote a response to this post that explains exactly how interface values that are nil are typed. It’s more complicated than I thought! I’m not sure I have another Rust & Postgres blog post in me…
Background
Programming language memory models answer the question of what behaviors parallel programs can rely on to share memory between their threads. For example, consider this program in a C-like language, where both x and done start out zeroed.
Mugo is a single-pass compiler for a tiny subset of the Go programming language -- just enough to compile itself.
Object-oriented programming is out of fashion now, and it has been for a while. Rarely are new programming languages intentionally object-oriented. And there are good reasons for this: OO often requir…
In one of my recent training courses, a student informed me that both clang-tidy and PVS-Studio were complaining about some code of the form
The functional programming analog of an object-oriented design pattern
When I was a kid, I wrote a BASIC program to explore Conway’s Game of Life on my 8088. It was painfully slow, so I began an assembly rewrite. But I failed at Life: I abandoned the project in frustration because I kept freezing up my system.
Over the last couple of years me and my colleagues here at doctronic have been busy creating and maintaining more than a dozen of individual software systems for our clients.
