Yesterday I put out a little screencast showing some ways of Creating Ruby Hashes. James Edward Gray II pinged me on Twitter and basically said “Great screencast! Ooh, but you forgot this! Ooh, and this! And this!” and so of course there was nothing to do for it but invite him to do a pairing screencast with me.
This video is a bit of a weird hybrid. You get 7 minutes of podcall, then 18 minutes of screencast, then another 12 minutes of podcall. James shows off some of the “hot new awesomeness” of Ruby 1.9, and then points out that this awesomeness has been around for a couple of years and nobody’s using it, in spite of it having been in the current Pickaxe for nearly as long. Along the way we talk about regular expressions, testing dogma, and the importance of never squashing creativity in the open source community. All in all, an incredibly fun time for me. James threatened to come back and do another one with me on regular expressions, and I’m mentioning it here in writing so that everybody knows I plan on taking him up on that offer.
No podcast, because half of it is us typing into a shared screen session. But here’s the video. You may need to watch it on Vimeo or download it to see the font clearly.
Pat and I are back with another installment of our weird little video podcast! Today we talk about the Single Responsibility Principle, which is at the heart of SOLID. SRP pushes everything out into little classes, and if you want to get anything complex done (like, for instance, you might find in any real program with more than 10 lines of code), you have to build a sort of aggregator object or manager class. Our key question for this podcall is “Even though SRP makes this aggregator class necessary, does the aggregator class itself violate SRP?”
As always we had a great time talking about it. Viewers will be happy to know that we kept the fart jokes to a minimum (I opted to go with Registered Sex Offender humor instead). Viewers distressed by the amount of airtime my cats got last time (and you know who you are, George S. from Utah) will be happy to know that my cat only farts in the microphone once, and she gets less than 10 seconds of airtime doing it. Fair warning: she really works those 10 seconds.
