QEMU 4.0 adds micro:bit emulation support
micro:bit emulation support is available from QEMU 4.0 onwards and can be used for low-level software testing and development. Unlike existing micro:bit simulators, QEMU performs full-system emulation and actually runs the same ARM code as the real hardware. This blog post explains what full-system emulation means and…

Alan Kay and OO Programming
Dr. Alan Kay invented the term "OO Programming", but he states that modern OO programming isn't what he meant. What did he mean?

Containers, microservices, and service meshes
There is a lot of material out there about services meshes, and this is another one. Yay! But why? Because I would like to give you the perspective of someone who wish service meshes did exist 10 years ago, long before the rise of container platforms like Docker and Kubernetes. I’m not claiming that this perspective…

Jumping Back and Forth
The order that our mind imagines is like a net, or like a ladder, built to attain something. But afterward you must throw the ladder away, because you discover that, even if it was useful, it was meaningless.

Modern SAT solvers: fast, neat and underused
In the previous two parts we used a SAT solver as a black box that we feed input into, and it will (usually quickly) spit out an answer. In this part, we will look at how SAT solvers work and what heuristics and other tricks they employ in their quest for performance.

Shell Completions in Rust
If you've ever hit the tab key while typing commands in the shell, you are familiar with the value of shell completions. Bash has some default completion behavior, which is why you can type hel<TAB> and end up with help . It is also possible to add additional completion scripts which define the completion behavior for…

Translating an ARM iOS App to Intel macOS Using Bitcode
When Apple introduced Bitcode and made it mandatory on watchOS and tvOS, they kinda hand-waved away questions about why it existed, with nebulous claims about it being useful to tune-up binaries by utilizing the latest compiler improvements.

Dear Programming Job Applicants (2010)
This article is written with considerable snark–put on your flameproof suit if needed. I’m not actually a jerk when interviewing people, but I do get frustrated when candidates fail to do basic preparation. If you’re unsure about how to prepare for a programming interview, read on… I know this might come as a shock to…

Building better software with better tools: sanitizers vs. Valgrind
We often have to write code using permissive programming languages like C and C++. They tend to generate hard-to-debug problems that can crash your applications. Thankfully, many compilers offer "sanitizers". I discussed them in my post No more leaks with sanitize flags in gcc and clang. I strongly encourage the use…

Zero Cost Abstractions
The idea of a zero cost abstraction is very important to certain programming languages, like Rust and C++, which intend to enable users to write programs with excellent performance profiles with relatively little effort. Since this idea is fundamental to the design of Rust and my work, I want to investigate, for a…
