  • The REPL: Issue 2

    The Little Mocker

    Uncle Bob writes about mocks, stubs, doubles, spies, etc. He explains the differences between them, how and when to use them. The examples are in Java, but are easily followed even with vague familiarity with the languge.

    Back To Basics: Regular Expressions

    The fellows at thoughbot give a great primer on regular expressions in ruby. The examples are easy to follow and yet manage to explain a lot of more advanced concepts like capture groups, expression modifiers and lookarounds.

    Goto Fail, Heartbleed, and Unit Testing Culture

    Back when Apple’s Goto Fail bug was news, my reaction to this was: How did the introduction of this bug pass the tests.

A few minutes later I get an email from the credit union in which I am notified that I have a secure email waiting at the other side of a link. Upon clicking, you visit a Barracuda Network site, in which I a need an email and password to access. As I have not established a password in the past, I just need to type a new one and confirm it in another box. Easy.

  • Killing Me Softly

    Every once in a while, a process is stuck and doesn’t want to respond. I usually just found the process id by using ps and then ran kill -9 <pid>. Why? Cargo-culting, mostly.
