Every project can benefit from a robust continuous integration pipeline that builds your application, runs tests, lints code, verifies code quality, runs vulnerability analysis and more. However, building such pipeline takes a significant amount of time, which doesn't really provide ...
This article explains a straightforward approach for generating Perfect Hash Functions, and using them in tandem with a Map implementation called ReadOnlyMap. It assumes the reader is already familiar with concepts like hash functions and hash tables. If you want ...
This article assumes the reader is already familiar with the C programming language and some basic concepts concerning hash functions. The target audience (as is often the case on my blog) is undergrad CS students or seasoned developers who, just ...
When it comes to performance optimization, people usually focus only on speed and CPU usage. Rarely is anyone concerned with memory consumption, well, until they run out of RAM. There are many reasons to try to limit memory usage, not ...
Before any new feature, change or improvement makes it into Python, there needs to be a _Python Enhancement Proposal_, also knows as PEP, outlining the proposed change. These PEPs are a great way of getting the freshest info about what ...
We all spend a good chuck of our time debugging, sifting through logs or reading tracebacks. Each of these can be difficult and time-consuming and in this article we will focus on making the last one - dealing with tracebacks ...
