A week ago I wrote about Perrin numbers, numbers Pn defined by a recurrence relation similar to Fibonacci numbers. If n is prime, Pn mod n = 0, and the converse is nearly always true.

Summer typically brings lots of vacation time for people. Instead of sitting around and being lazy, why not take the time to learn a new programming language? I am not recommending a specific language over others at this time, but providing a long list of languages based on GitHub and TIOBE. I have not tried to categorize or validate this list of languages in any way, so please do not complain...

For episode 20, we tackle the topic of tooling proficiency on your release engineering, ops, and development teams, specifically through the lens of version control tools. Version control is becoming a ubiquitous part of the “DevOps movement,” and we talk through what level of understanding should be expected, what level of training should be provided, and whether those are different for...

I heard someone mention the other day that they have forgotten more programming languages than most developers have learned and it made me remember all the suggestions to learn a new language every year.  I have probably even made this suggestion before.  As I thought about it I realized that it isn’t important for it to be a language that you learn, it is just important that you...

I’ve flipped my blog from one theme to another, while keeping it within GitHub Pages. On the way, I’ve been deleting and updating cruft. But what should I do about my historical links to http://www.nosoftwarepatents.com though? Clicking through to www.nosoftwarepatents.com leads me to believe that it’s ‘parked’ at some moment in 2007. The style’s archaic, and the logos are unusable,...

There’s more and more buzz around estimates and #noestimates in software development. People like to write bold statements and go extreme about things in blogs. Usually, personal dialogues are much more balanced. Some hate estimates and believe it’s a useless activity. Some defend it with arguments of arguable truth. I want to dig into intrinsic estimates complications, what people mean by...

It's Thursday already, so time for another code puzzler. The idea is simple: solve the coding problem as efficiently as you can, in any language or framework that you find suitable. Note: Even though there really is nothing stopping you from finding a solution to this on the internet, try to keep honest, and come up with your own answer.  It's all about the participation!Sudoku Puzzle...

I’ve been seeing quite a few posts on Hacker News lately about why you should not work too hard and even saying you should work less than 35 hours a week.
