Classes vs. Data Structures
Or rather, an object is a set of functions that operate on implied data elements.

How Swift Achieved Dynamic Linking Where Rust Couldn't
For those who don’t follow Swift’s development, ABI stability has been one of its most ambitious projects and possibly it’s defining feature, and it finally shipped in Swift 5 . The result is something I find endlessly fascinating, because I think Swift has pushed the notion of ABI stability farther than any language…

I learnt C++ in 2018 and have no regrets
My quest for relearning C++ started in November 2018. I have been reading + blogging + writing C++ from then. I would like to reflect on my journey a bit. Before I begin, I would like to state that th

D as a C Replacement
Sircmpwn (the main developer behind the Sway Wayland compositor ) recently wrote a blog post about how he thinks Rust is not a good C replacement . I don’t know if he’d like the D programming language either, but it’s become a C replacement for me.

Go Creeping In
I’ve seen the inside of the Google and Amazon tech stacks. There are common threads that run through them and also, I bet, through most BigTechCos. Here and there down the stack is a lot of C++ and vestigial remnants from earlier days, Perl or PHP or whatever. Out in front of humans, of course, JS. But in between…

Why I Don't Like Golang (2016)
When I first started programming in Go, my summary of it was, “The good things are great and the bad things are weird and I can live with them.” After another three years and a few large projects in Go, I no longer like the language and wouldn’t use it for a new project. Here are 10 reasons why, in no particular order.

Learning Haskell is no harder than learning any other programming language
It has still often been difficult to find answers to my questions. I think this is largely due to the fact that when discussing things with the average Haskell programmer, I feel like I have a fourth-grade education.

Learning Parser Combinators with Rust
This article teaches the fundamentals of parser combinators to people who are already Rust programmers. It assumes no other knowledge, and will explain everything that isn't directly related to Rust, as well as a few of the more unexpected aspects of using Rust for this purpose. It will not teach you Rust if you don't…

Lisp is not based on the Lambda Calculus
How do you condense a 30 minute talk in 5 minutes? Should you even try? These are the questions I struggled with when someone nudged me to register for the lightning talks. My talk was 30 minute long because I was to jump in if a last-minute incident would prevent someone to get on stage. Call me the backup speaker…

C++ 20: The Core Language
My last post C++20: The Big Four started with an overview of concepts, ranges, coroutines, and modules. Of course, C++20 has more to offer. Today, let’s continue my overview of the core language.

Racket Is an Acceptable Python
A little over a decade ago, there were some popular blogposts about whether Ruby was an acceptable Lisp or whether even Lisp was an acceptable Lisp . Peter Norvig was also writing at the time introducing Python to Lisp programmers . Lisp, those in the know knew, was the right thing to strive for, and yet seemed…

Update on await syntax in Rust
In my previous post I said that the lang team would be making our final decision about the syntax of the await operator in the May 23 meeting. That was last Thursday, and we did reach a decision. In brief, we decided to go forward with the preliminary proposal I outlined earlier: a postfix dot syntax, future.await…

Why Clojure?
I’ve programmed systems in many different languages; from assembler to Java. I’ve written programs in binary machine language. I’ve written applications in Fortran, COBOL, PL/1, C, Pascal, C++, Java, Lua, Smalltalk, Logo, and dozens of other languages. I’ve used statically typed languages, with lots of type inference…
