Avoid nil-checks. Code confidently. Be happy.

This post is about pretty code, how to get nil out of the way, and be more confident.

Does this code look familiar?

How about this?

What is Dependency Injection

If you are a developer, chances are very good that you know what Object-Oriented (OO) code is. You might have also heard about OO Design Patterns, things like single responsibilities, decoupled code, and my subject here: Dependency Injection (DI).

OO Design patterns help you write code that is easier to change, and easier to test. Being quite abstract concepts, they apply to many modern programming languages, including Java, Ruby and PHP. Each language has its own way to do things, thus each language implements the concepts in a different way. Some implementations are similar, others not so much. In this article I’ll talk about Dependency Injection with a special focus on web development. I’ll explain what DI is, and I’ll elaborate on Ruby’s implementation. Finally, I’ll compare the Ruby approach with PHP’s view on DI.

A Web Developer’s OS

What must an Operating System do to satisfy web developers’ needs? This is a tricky question, as each person is a whole different world, so it’s impossible to have a single answer to satisfy every person.

One could say “Well, because each person is different, the OS must be able to adapt to all different kinds of people”. Basically, meaning the OS must be easy to customize. This is great, but when is it too much customization? Systems that are very customizable also tend to be hard to use. In this post I’ll compare the three most used Operating Systems out there, namely Windows, OS X and GNU/Linux. I like FreeBSD but the userbase is so small I sadly won’t consider it here.

When talking about customization, I’d say Linux is king. Windows, on the other hand, is not natively customizable, but easy to use and with sane defaults. OS X gets the best of both worlds. That’s just my humble opinion, as I don’t consider myself to be a full power user of any of those systems, I just use them to get work done on a daily basis.

Ruby scripting in FileMaker

[Authored by Alex G]

There are many cases where FileMaker’s scripting isn’t always the best tool for the job and where a language like Ruby can bring a lot of power to your FileMaker development. The following is a description of a simple technique for using ruby scripts from within a FileMaker solution without the use of a plugin. I’ve found this technique useful for employing regular expressions for complex text parsing, making web requests to work with web APIs, and for parsing and generating XML and other serialized data structures. Ruby has a wealth of great libraries for doing anything you can imagine and is just plain fun to write.

Never write a render_foo method again

[Authored by Ian]

I’ve probably written a hundred render_not_found methods in my life as a Rails dev. Usually they just render a static file under /public, and maybe, if I’m feeling nice, give an XML response. No more!

Setting the Commit Author to Pair Programmers’ Names in Git

[Authored by Sam]

In beezwax’s webdev division we generally work in pairs, but our commit logs didn’t used to show this. We wouldn’t bother to reconfigure the git author every time we sat down with a new pair so our git log only recorded one of the programmers’ names. Bryan Helmcamp has a nice script for setting your git commit author in pair programming situations. Here’s another one which works interactively.

Remote Pair Programming: Part II: Sharing the server

[Authored by Sam]

[01/04/15 – Editor’s note: This post was written in 2008. In 2015 we don’t use this “reverse ssh tunnel” method much anymore, but the technique is still interesting.]

In my last post I described how to use reverse ssh tunnels and screen -x to setup a remote pair programming environment.

Several people have commented that this works well for sharing a console based editor (vim, emacs) but that there is no way for the remote pair to look at how things are rendering in the browser. Well here’s a super simple way to use ssh tunnels to share your development server too. I’ve seen variations on how to do this (Advanced Rails Recipes: Pragmatic Programmers has one). The advantage to the below method is it requires no server configuration and is very secure from snooping.
