  A Month With Scala

Although I’ve played around with Scala for the few months, these efforts largely involved simple scripts and casual reading. It wasn’t until last month that the opportunity to use Scala in a large scale project finally arose and I dove right in. The project was a typical REST based web service built on top of Amazon’s Elastic Beanstalk, SimpleDB, S3 and Redis*. First off let’s talk about why I chose Scala in the first place. After spending a good deal of my las...

  Your Code is My Hell

It occurred to me recently that my experience as a Rails developer may be somewhat unique.I often get brought in to help preexisting Ruby/Rails projects evolve and mature in a sustainable way. As a result, the vast majority of Ruby projects I’ve worked on have been well-established by the time I arrived. In fact, offhand I can only think of one commercial greenfield Ruby project I’ve participated in. All the rest have been “legacy” from my perspective, in the ...

  SQL Server: Removing Deprecated Code and Future Proofing your Queries

New features are added with every release of SQL Server and as a result, some features get removed or deprecated. Deprecated features are features that are still operational (for backward compatibility) but will be removed in a future version. Deprecated features can be of two types: those that will be deprecated in a future version and those that will be deprecated in the next version.In this article, we will explore how to track deprecated code and correct it. I will also share our observation...

  How I Became a Programmer

I posted a very brief response to a post on HackerNews yesterday challenging the notion that 8 weeks of guided tutelage on Ruby on Rails is not going to produce someone who you might consider a "junior RoR developer." It did not garner many upvotes so I figured that like most conversation on the Internet it faded into the general ambient chatter. Imagine my surprise when I woke up to couple handfuls' worth of emails from around the world asking me what I did, how I did it, an...

  Functional Programming For Object Oriented Programmers

After recently remarking about how I finally "got" functional programming I was asked by one of my millions of twitter followers... ¬_¬ to write up an explanation of a small F# program spoken in terms that fellow O-O programmers would understand. Before I become too entrenched into the functional programming way of thinking, that is, and can't explain it anymore. As a former tutor this is one of the major problems with being able to teach something once you understand it. You've ...

  Making Computer Science a Requirement?

This US News article points out a growing interest among colleges and universities to make basic computer science a required course for all students. Georgia Tech already does this. The article points out that universities not normally considered to be science/technology-heavy are leaning this way too: Every student at Montclair State University in New Jersey must complete a computer science in order to graduate. For most students, that course is Introduction for Computer Appl...

  Performance is a Feature

We've always put a heavy emphasis on performance at Stack Overflow and Stack Exchange. Not just because we're performance wonks (guilty!), but because we think speed is a competitive advantage. There's plenty of experimental data proving that the slower your website loads and displays, the less people will use it. [Google found that] the page with 10 results took 0.4 seconds to generate. The page with 30 results took 0.9 seconds. Half a second delay caused a 20% drop in traffic. Half a seco...

  The Most Effective Stretches and Yoga Poses for Programmers

Programming software takes a tremendous amount of focus and effort. Working hard to transform code into software is an exciting feeling. It’s easy to get lost in your work as the hours fly by. I’ve done this many times. However, writing code can also be frustrating in many cases. I’ve been a programmer for many years, and I still spend hours debugging. Most of the time this level of debugging requires sitting down and focusing. After many years of this, you will be a prime ca...

  Stop Designing Pages And Start Designing Flows

For designers, it’s easy to jump right into the design phase of a website before giving the user experience the consideration it deserves. Too often, we prematurely turn our focus to page design and information architecture, when we should focus on the user flows that need to be supported by our designs. It’s time to make the user flows a bigger priority in our design process. Design flows that are tied to clear objectives allow us to create a ...
