A Father’s Influence

Blogs

My dad and I had a very interesting and complex relationship. Some of this was due to his complex upbringing. His father was an alcoholic who died fairly early in his life, and his mom, well, his mom liked me a lot, but she was a messed up woman in many ways. After his father … Read more

Building a Great Technical Team

Editorials

The process of putting together a team of technical people once was largely centered around getting a group of similarly minded people. How people worked was valued more than how well they could accomplish their job. Finding people who could work together smoothly was a big focus when picking new team members, and was a … Read more

Finding a character in every character string by elimination

Blogs

A few weeks ago, a coworker had a scenario where he was trying to import a large amount of data into some format (I think it was JSON, but I think it was a special limitation… that isn’t really important to the solution), and it didn’t allow certain characters.

You are never too old to learn an important lesson. Like most programmers, I read programming language documentation for one of two reasons. 1. You have just found out about something new 2. You find out that you were wrong about something you thought you had read the first time, probably 10 years ago. Today’s … Read more
