C++ Coroutines
C++ is late to the coroutine party, compared to other programming languages, but they are part of C++20. Prior to coroutines, a C++ programmer had two choices, roughly speaking:

Everyone says assembly is untyped—everyone is wrong
TL;DR: I believe Odin's inline assembly is currently the best out of any language.The most important aspects are of this article listed below. I am not aware of any other assembly (GCC/Clang/Rust/Go...) that would combine all of these aspects:Inline assembly is organized into "templates", similar to and callable as…

JavaScript is Dead. Long Live JavaScript
For 16 years, JavaScript has been the language of the web browser. This language has enabled the building of compelling web applications and contributed to the success of the web. Other scripting languages could have filled the role JavaScript does but JavaScript was in the right place at the right time. Microsoft…

J Notation as a Tool of Thought
Kenneth Iverson’s 1964 language, APL, won him the Turing Award. His award lecture, Notation as a Tool of Thought, argued that better notations would lead people to deeper insights about mathematics. He provided a number of examples ranging across linear algebra, arithmetic, probability, and logic. Unfortunately, most…

Using Zig to Unit Test a C Application
Zig is a new, independently developed low-level programming language. It’s a modern reimagining of C that attempts to retain C’s performance while embracing improvements from the last 30 years of tooling and language design. Zig makes calling into C code easier than any other language I’ve used. Zig also treats unit…

Undefined vs. Unsafe in Rust

Hacking Coroutines into C
A while ago, I was part of a team developing embedded software. The software was deeply rooted in state machines - dozens of them—spread across multiple functions. While this architecture is common in embedded development, especially for systems without an operating system, I started to question: Is this really the…

Several core problems with Rust
I used to call myself a Rust hater, but really I was doing it just to compensate for the perceivable fanboyism e.g. Rust tops on stackoverflow surveys as most-loved language. There are many reasons to hate C++, and I hate C++ too. Lots of people were waiting for a better programming language, but got Rust instead.

Designing a Programming Language
Programming languages come in a variety of different paradigms. Even so, there tend to be two main camps along the language front. There are static languages and there are dynamic languages. To avoid too much history and any sort of in-depth analysis, this article will simplify things with a number of assumptions. One…

Goroutines: The concurrency model we wanted all along
Goroutines are the single feature that distinguishes Go from other languages. They look very much like threads, but they are cheap to create and manage. Go's runtime schedules goroutines onto real threads efficiently so you can easily create lots of goroutines.

History of Spring Framework and Spring Boot
Spring framework is arguably one of the most popular application development frameworks used by java developers. It currently consists of a large number of modules providing a range of services. These include a component container, aspect oriented programming support for building cross cutting concerns, security…

Why split lexing and parsing into two separate phases?
“lex and yacc” are two terms that are used together so often that they can seem indivisible. lex takes a string as input and divides it up into lexemes (roughly speaking “words”) and yacc takes a sequence of lexemes and parses them. Since some parsing approaches such as recursive descent parsing unify these phases…

The Go Compiler Needs to Be Smarter
One of my favorite languages is the Go language. I love its simplicity. It is popular and useful in a cloud setting. Many popular tools are written in Go, and for good reasons. I gave a talk on Go last year and I was asked for a criticism of Go. I do not mind that … Continue reading The Go compiler needs to be smarter

Go: The Good, the Bad and the Ugly
This is an additional post in the “Go is not good” series. Go does have some nice features, hence the “The Good” part in this post, but overall I find it cumbersome and painful to use when we go beyond API or network servers (which is what it was designed ...
