In order to hide your IP address and to try and limit throttling when web scraping, it might be a good idea to use a proxy such as Tor. This post describes how to use Python based web scraping tools and Tor to hide yourself when scraping websites for data. However, it can also be used more broadly when using Python to…
A paper on debugging non-deterministic concurrency issues interactively.
This is a talk and slides from Narrascope 2019 , held at MIT, Boston, on 14-16 June 2019. It's a sequel to a talk given in London a year earlier , when I went into "literate programming" at greater depth, but when the design of Inter was more embryonic. I'd like to thank the Narrascope organisers for fitting me in to…
This type of highlighting is ideal for assembly. With it, the things that shouldn't seem similar usually don't.
The recent Zoom vulnerability is just one of many examples which show us that many developers do not understand how CORS works
This post describes a compile-time technique for catching use-after-move bugs in modern C++. It’s currently used to prevent some mistakes in the Serenity Operating System.
I wanted to give an update on the status of the “async-await foundations” working group. This post aims to cover three things:

I've just finished teaching a four-day course introducing software engineering for the first time. My plan is to refine the course (I'm teaching it again in October), and it will eventually become the basis for doctoral training programmes in research software engineering at Oxford, and part of a taught Masters. My…
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…
I’m a huge proponent of designing your code around the data, rather than the other way around, and I think it’s one of the reasons git has been fairly successful… I will, in fact, claim that the difference between a bad programmer and a good one is whether he considers his code or his data structures more important…
This article is based on my GopherCon Singapore 2019 presentation. In the presentation I referenced material from my post on declaring variables and my GolangUK 2017 presentation on SOLID design . For brevity those parts of the talk have been elided from this article. If you prefer, you can watch the recording of the…
How to use Python to generate 3D SVG.
For my ten years in the Erlang community, I decided to cover a few topics such as hype phases and how this related to Erlang, the ladder of ideas within the language and how that can impact adoption, what changed in my decade there, and what I think Erlang still has to bring to the programming community at large.
I recently updated minor and patch versions of the gems our Rails app uses. We want to keep dependencies fresh, bugs fixed, security vulnerabilities addressed while maintaining a high chance ...
So I've been curious about what kinds of displays you can connect to the Pi-series single board computers for a while. I happened to accidentally order a few. Among others an eInk display. I ordered the PaPiRus ePaper. It ended up being dead on arrival and then out of stock so I received an Inky to replace it. Fair…
This blog post shows tips and tricks to write resilient and idempotent bash scripts.
Course overview Memory leaks and dangling pointers are the main issues of the manual memory management. You delete a parent node in a linked list, forgetting to delete all its children first -- and your

The web platform is the delivery mechanism of choice for a ton of software these days, either through the web browser itself or through Electron, but that doesn’t mean there isn’t a place for a good old fashioned straight-up desktop application in the picture.
It's a C test. If you think you know C, take this test. It only has 5 questions.
This issue came up recently for a high profile new gadget that has made the transition from Micro-USB to USB-C in its latest version, the…
After a rather long break from programming and Clojure I decided give them another go. When it comes to managing Clojure projects, Leiningen is de-facto standard tool. Recently, Clojure CLI tools are becoming more and more popular, though. Switching to yet-another-build-tool doesn't have any pragmatic value, but it's…
Updated (2023-05-08): the Go compiler keeps evolving and it takes time to keep up with changes. While the general gist of this post remains true and it's worth reading to understand how the compiler works on a high level, the details of the modifications are slightly different now.
