Why Codeless Software Is Doomed to Fail
Every couple of years, the hope surfaces that a simple graphical interface will replace teams of developers. Business people to quickly and easily create beautiful expressions of their ideas and launch them into production seamlessly. A handful of startups in every generation take up this challenge, and they mostly…

Is C# a low-level language?
I’m a massive fan of everything Fabien Sanglard does, I love his blog and I’ve read both his books cover-to-cover (for more info on his books, check out the recent Hansleminutes podcast).

We decided to go for the big rewrite
For small programs, where it would be a question of a few days or a few weeks to rewrite them, it will generally not be worth pondering this question for very long, and in most cases it will be better to just get started on either fixing the existing implementation or on rewriting it. For small programs it is possible…

Applying the Gestalt Principles to Code
It’s one of the most repeated phrases in software, but is also quite easy to forget - you spend more time reading code than you do writing it. According to the…

How to Make Python Wait
For many types of applications, at times it is necessary to pause the running of the program until some external condition occurs. You may need to wait until another thread finishes, or maybe until a…

On lists, cache, algorithms, and microarchitecture
Lists are rather hardware-unfriendly data structure. However, having a closer look at why is that and what can be done to improve this can provide an interesting insight into how high-level algorithms performance is affected by the processor microarchitecture.

Initialization in C++ is Seriously Bonkers
I was recently reminded of why I think it’s a bad idea to teach beginners C++. It’s a bad idea because it is an objective mess—albeit a beautiful, twisted, tragic, wondrous mess. Despite the current state of the community, this post is not a polemic against modern C++. This post is partly a follow-up on Simon Brand’s…

Avoiding Webscraping Throttling Using Python and Tor as a Proxy
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…

Compilers for Free
I’m fascinated by programming, and by metaprogramming in particular. When Ruby programmers talk about metaprogramming they usually mean programs that write programs , because Ruby has various features — like BasicObject#instance_eval , Module#define_method and BasicObject#method_missing — which make it possible to…

Roguelike Tutorial: Up-to-Date and Literate
