Nibble Sort
A while back, John Regehr posted the Nibble Sort Programming Contest on his blog. The objective was to write a program that sorts the 4-bit components (nibbles) of 64-bit words as fast as possible. For example, 0x42badc0ffeed00d5 should result in 0xffeedddcba542000 after sorting.

Writing a Debugger from Scratch: Stacks
(New to this series? Consider starting from part 1) At the end of the last post, DbgRs could finally set breakpoints. That was the last really critical feature needed for controlling execution of a program. Now that it can stop on an arbitrary function or code location, the next step is to find more information about…

Do you really need foreign keys?
Foreign keys are a bit like that well-intentioned friend who insists on double-checking everything you do. They’re often recommended as a must-have for enforcing referential integrity checks in your database.

Solving the regex of madness, and snarky answers on StackOverflow (2019)
This infamous answer [https://stackoverflow.com/a/1732454/7488] on StackOverflow have reached meme status. The question is about finding opening tags in XHTML using a regular expression, and the answer makes it abundantly clear that this is not possible - and you will surely go mad if you try. The

Another go at the Next Big Language
2007 was a different time for languages. While Java held the popular crown, the mainstream programming community were still coming to terms with Java 6. Released 3 months earlier, it was very much an evolution of the Java 5 watershed. Its arrival heralded the end of life for Java 1.4 and represented an opportunity to…

C and C++ Aren't Future Proof
My hope would be option 1 for application code (as opposed to the “systems code” that you have there): fewer and fewer people use these languages to write application code. Moreover, I think that’s probably happening to some extent.

What factors explain the nature of software?
I sometimes find myself asked to give advice on how organisations should go about creating software, but often my advice doesn’t gel with those who sought it. Sometimes that’s because only one answer was ever considered acceptable; sometimes I am ignorant of important wider context and my answer is unworthy of…
