Gregg’s “Speeding up Ruby, without the Rails” Presentation
He points out that the C library stuff is going to cause blocking, because Ruby’s threading manager doesn’t know when it can stop execution. He demos this with mysqlplus, showing 10 queries with the blocking driver, and then showing mysqlplus which is the non-blocking driver. 10x speedup.
He points […]

Thursday AM Keynote by Matz
This is Matz: http://en.wikipedia.org/wiki/Yukihiro_Matsumoto
He’s talking about his love of languages, and why he got into Ruby.
He’s addressing some of the criticisms, that it’s slow, poorly implemented, embedding issues…he says the list of complaints goes on forever.
But, now he’s talking about why is Ruby good. He says people say it’s enjoyable, that […]
I’m here at RubyConf with some of the Cloudspace team. Also, Corey has come in from North Carolina, gracing us with his presence, and his beard.
I’ll probably be posting from some of the sessions as I go. Long posts will be on this blog, short things and ‘overheards’ will be on my Twitter.
If you’re here, […]
As a follow-up to yesterday’s post about Matt Williams’s presentation on Ruby and Arduino, here are some videos, slides, and notes from the ORUG site.
You absolutely must check this out. The field of robotics is going to play such a massive role in all of our lives over the next few years, and this is […]
Just got back from this month’s ORUG, where Matthew Williams gave a presentation on using Ruby to control an Arduino. Matt is a very natural speaker, and the presentation was great. He even demoed a bartending robot he built, which should be featured on Make very soon.
I took notes during the presentation, and they are […]

After lots of code, tests, and fun, I’ve produced a Firefox extension to add a useful, new feature to Twitter, as opposed to writing Twitter extensions as a joke
Simply put, the extension provides autocomplete for Twitter usernames from your own list of friends while you’re using the web interface at twitter.com. It’s totally […]

OK, here’s the deal, as quick as I can put it, but with enough words that Google will correctly index this post and make this information easier to find for the next person who needs it.
Let’s say you’re developing a Firefox extension, and you need to look at the HTML of the page. You know […]

OK, so the title of this post might be a bit overstating.
But, if you work with Javascript and need to use dates/times, you should absolutely check out a JS library for formatted dates and times by Steven Levithan (who is obviously cool; his blog is titled “Flagrant Badassery”).
It’s a library that extends the stock Date […]

Detecting page loads is a useful ability. It’s easy enough to throw in a
gBrowser.addEventListener(”load”, function_name, true);
But, it causes extra events to get generated. There’s load events occurring in the browser that aren’t page loads. The trick to detecting real page loads (but not Back/Forward navigation when the page is still in memory — only page […]

Corey sent me a link to Ubiquity, a dynamic-mashup-maker-that-reminds-me-of-Quicksilver. The video is cool looking, I may keep an eye on this project to see where they go with it. I think it’s a useful tool if you have these specific tasks coming up often, and the ability to make new commands is neat.
