While looking at performance optimizations for a rails project, I noticed these lines in my debug console: ActsAsTaggableOn::Tag Load (0.5ms) SELECT “tags”.* FROM “tags” INNER JOIN “taggings” ON “tags”.”id” = “taggings”.”tag_id” WHERE “taggings”.”taggable_id” = $1 AND “taggings”.”taggable_type” = $2 AND (taggings.context = (‘tags’)) [[“taggable_id”, 103], [“taggable_type”, “Prediction”]] This makes sense,
As some readers might know, I’ve recently joined the team at Knoda. Based in Kansas City, Knoda provides people with a way to make their predictions, let their friends (and enemies) vote, and hold everyone accountable to the results. Sound like fun? Well, hurry over to the App Store and
While visiting the Play Framework website, I noticed a new banner in the top right corner. Perhaps “new” isn’t correct – I’ve been almost exclusively in Node.js and Rails land for the past 6 months, so I might be behind the times on this one. Following the links takes us
Update 10/10/2013 – A good point was made that doing the array creation isn’t really going to be different between the libraries.

Any sizable web application needs validation. Doing it yourself is for the birds, so I wanted to incorporate a backbone plugin to help solve the problem.

Well, lets remedy
What’s your database of choice? For the next few months, I’ll be working with the team at LocalRuckus, building a new Node.js API and application. As a small shop with no dedicated Sys Admin or Dev Ops, its essential that we find Node.js hosting that is flexible, fast, and cost-effective.
On a recent trip to San Diego, my wife and I crossed the U.S./Mexico border at San Ysidro to visit the lovely city of Tijuana. A 5 minute walk across the border was all it took to enter Mexico. After a few hours of touring the Mexican shops (and the
Heroku provides a free add on for running scheduled jobs. This provides a convenient way to run scheduled tasks in an on-demand dyno, freeing your web dynos to focus on user requests. I’m currently writing a node.js application in coffeescript that has some modest job scheduling needs. Heroku’s documentation
Node.js gets a lot of well-deserved press for its impressive performance. The event loop can handle pretty impressive loads with a single process. However, most servers have multiple processors, and I, for one, would like to take advantage of them. Node’s cluster api can help. While cluster is a core
