You may have noticed that quite a lot is happening in the Midgard land. Nowadays Midgard2 itself is a generic content repository that can be used for both desktop and web applications. Midgard MVC is a generic web framework for PHP5 that can be used with Midgard2 or without it. And then there is Midgard Create, the…
How to disable heap (dynamic memory allocation) in an embedded application? This article goes into the details of linker files and how to detect dynamic memory allocation.
Unicode is just too complex to ever be secure.  — Bruce Schneier, 2000 Over the last 25 years Unicode has succeeded. It hasn't displaced all other character encodings, but it's clearly on its way there. It's supported widely enough that it's a compatible choice, new projects use it, and it's becoming the…

You sometimes feel the need to make all of your integers positive, without losing any information. That is, you want to map all of your integers from 'signed' integers (e.g., -1, 1, 3, -3) to 'unsigned integers' (e.g., 3,2,6,7). This could be useful if you have a fast function to compress integers that fails to ……

We've been working in the responsive realm for a while now and one of the most painful parts of the process is dealing with images. Large images can cause extremely long load times on small devices that might not have a huge data bandwidth. There have been many "best practices for now" movements to deal with this.
The Database Toolkit for Python
Posted by Mariusz Felisiak on Sept. 21, 2021
You see, there are two memory accesses per one character of the input string (at average). Hence, the total number of all memory accesses can be len*2 at worst.
Ruby's `private` keyword means something different compared to basically all other object-oriented languages. Most other languages don't even have a feature matching what Ruby calls `private`, but incredibly, Scala does, which it calls `protected[this]` (meaning
Research has begun to reveal many algorithms can be expressed as matrix multiplication, suggesting an unrealized connection between linear algebra and computer science. I speculate graphs are the missing piece of the puzzle. Graphs are not only useful as cognitive aides, but are suitable data structures for a wide…
There’s not a whole lot on TLA+ technique out there: all the resources are either introductions or case studies. Good for people starting out, bad for people past that. I think we need to write more intermediate-level stuff, what Ben Kuhn calls Blub studies. Here’s an attempt at that. Most TLA+ properties are…
