June 4 2010: Okay, here's a link post

Quick links post: Gregory Brown is looking for comments and donations for a proposal for a Ruby Mendicant University, basically a rolling online Ruby course. Charles Nutter is interviewed by InfoQ on the state of JRuby. Yehuda Katz has a long post on various kinds of extensions in Rails 3 – gems, plugins, generators. This one I need to look at in some detail. The new RubyMine 2.5 beta integrates with Pivotal Tracker.

June 1, 2010: June, she'll change her tune

iPad Note I keep wanting to write about the iPad, but so, so many other people are writing about it that I’m not sure I have anything to add. More or less at random, I really liked the brief rant Joe Posnanski added in the middle of an otherwise-unrelated blog post, and Charles Stross’ typically complete take. Right now, I just would add that I still use it more than I thought, that the form factor makes more of a difference than I expected (being able to easily walk to show the screen).

May 13, 2010: The Rules of Agile Estimation

Top Story JRuby 1.5 is out. Highlights include improved Rails 3 support, better support for Windows, better FFI support, better startup time (yay!) and a lot of other tweaks and fixes. Book Update Still Cucumbering, hope to finish today. The book is still on sale, of course. And I’d still love to see more comments in the forum. I’ll be talking at Chicago Ruby on June 1, exact topic TBD (let me know if you have a preference), but I’m leaning toward talking about how to avoid test problems and write good, robust tests.

May 10, 2010: The need for eyeballs

Top Story Let’s start with this: there’s a small but embarrassing typo in the Pragazine article code. Especially since it was a) called out by the author of Mocha and b) was a direct copy from the book, and from the Lulu version before that, so it’s been public for about a year, and I’ve proofread that chapter at least five times. Which just goes to show… you never catch everything.

May 6, 2010: The day of promoting stuff

Top Story I’ll mention somebody else’s book, but don’t worry, I plan on doing it in a totally self-absorbed kind of way. Pragmatic released Using JRuby into beta yesterday, by the core JRuby team. Looks good, interested to see where they go with it. Because I’m me, I can’t help but compare the structure of the book with the Jython book I did. Biggest structural difference so far is that we were unable to assume a Python-savvy audience, so we felt we had to awkwardly teach Python for 100 pages at the start of the book, where as the JRuby book is able to teach Ruby in an Appendix.

April 13, 2010: iAd, youAd, weAll Ad

Top Story iPads. Lots of them popping up in and around work. Probably some more coherent impressions coming later. Wait, once again, Twitter has a big announcement after I start writing this. This time, they are going to start placing ads in the Twitter stream in various ways to be announced today. My quick reactions: a) I long suspected this day was coming, b) if the ads in clients are any guide, they aren’t particularly burdensome, c) implementation details will decide how irritating this is.

Hybrids In Bloom

A couple of big stories in the wide world of scripting languages running on virtual machine platforms. IronPython, the .NET implementation of Python created by Jython creator Jim Hugunin, released version 1.0. The two primary developers of the JRuby project, implementing a Java-based Ruby interpreter, were hired by Sun with the mandate to bring JRuby to 1.0. Unsurprisingly, I think this is all great. Programming hybrids are a beautiful thing.
