About Cal Evans

Many moons ago, at the tender age of 14, Cal touched his first computer. (We're using the term "computer" loosely here, it was a TRS-80 Model 1) Since then his life has never been the same. He graduated from TRS-80s to Commodores and eventually to IBM PCs.   For the past 10 years, Cal has worked with PHP and MySQL on Linux OSX, and when necessary, Windows. He has built on a variety of projects ranging in size from simple web pages to multi-million dollar web applications. When not banging his head on his monitor, attempting a blood sacrifice to get a particular piece of code working, he enjoys building and managing development teams using his widely imitated but never patented management style of "management by wandering around". Cal is happily married to wife 1.33, the lovely and talented Kathy. Together they have 2 kids who were both bright enough not to pursue a career in IT. Cal blogs at http://blog.calevans.com and is the founder and host of Nomad PHP

Why not just put all this in a database and check it once a minute instead?” I mean c’mon, working with MySQL is soooooo much easier than working with cron. Besides, a lot of these jobs… Read more »

Questioning Interview Questions

      No Comments on Questioning Interview Questions

“How would you update 10,000 servers located on the moon?” This was actually the question asked of me when I interviewed with Google. I’m not sure if the point was to figure out exactly what methods would work, or just to make the interviewer feel smugly superior. Either way, I hate these kind of pointless questions. Read on if you… Read more »

A Reverse Debugger for PHP…wait…WHAT?

      No Comments on A Reverse Debugger for PHP…wait…WHAT?

Honestly, when I originally tweeted this out I really wasn’t 100% sure what it did. You never know when you see things like “reverse debugger”. It’s one of those “I understand the words separately…” type of things. Then I watched the short video. HO-LY CRAP! Seriously, it is exactly what it says, it allows you to step debug forward AND… Read more »

Recently, in a cross-team effort, we upgraded our full web server fleet from PHP 5 to PHP 7. The whole upgrade was a fun project with some very cool results,… Read more »
