As some of you know, I am in the last steps of announcing my first iPhone application. We all know that every good iPhone application has a great marketing website with a screen cast. I myself was heavily inspired by the Tapbots Convertbot website while building my own and wanted a good way of embedding the screen cast. I think the last time I did an object/embed tag was god... around 2003 or something, seriously.

This guide is all encompassing but primarily focuses on the benefits of MacPorts, second the development stack for SQL Server and lastly on anything else a rails developer might need on OS X. If you are on a Mac, possibly running Snow Leopard and x86_64 is near and dear to your heart, this article is for you. If you do not "have" to use SQL Server, you can safely skip those sections and get to the Ruby1.9/Apache2/SQLite3/MySQL stuff.

What have I been up too lately? Well primary working my butt off in my day job and after that, I just finished a week of vacation. As an aside, I need to disconnect more often, my vacation was very relaxing. But what's more relaxing that doing things in the fresh outdoors? Well learning another programming language of course.

That is why this week I have seriously started learning Objective-C and iPhone application development. In fact I just got my approval today from Apple that I am a registered developer, see that pretty icon in the right column? So do you want to do the same? Below is a list of resources that I have found helpful to me. Let me explain something first, I am very tangential in my learning methods. Basically that means I take frequent breaks from my main course to learn deep details. For instance my main course is the iPhone SDK Development book. But I have found it very helpful to break early on and watch the Becoming Productive In Xcode videos. Knowing keyboard bindings and customizing my, dare I say it... IDE, just helps me get business done! Stay tuned for some updates.

I've been a TextMate user for a long time now and I'm still finding new things to do with it. Here recently I wanted to use the RubyAMP TextMate Bundle and was a little miffed to find that it was pointing to my OS X system ruby. The error message looked something like this when it went looking for my ruby/gems.

No such file to load -- appscript (LoadError) from

My MacBook is about a year old now and I've read in quite a few places that they could be upgraded to around 3.3GB of memory for this specific model. Unlike the latest MacBook which can "as advertised" accommodate 4GB of memory, the theory was that the Santa Rosa chipset can address all 4GB. It could very well be that technically my MacBook is only using ~3.3GB of that memory but the performance has been significant for a very cheap stick of RAM. I highly recommend Crucial.

I think this upgrade will have to hold me for some time. In general it has really helped my uptime. Odd as that is I think working with only 2GB of memory caused a lot of IO swap and memory corruption. Especially when stopping and starting so many different mongrels for local Rails development. As of this writing I have not found an issue that I have had to reboot for... uptime 10 days and going strong.

To keep my uptime going strong, I just purchased an app called iFreeMem today after reading about it on TUAW. Because I use PhotoShop ever now and then it really helped having this utility free up some memory that it would not release. So far it is working great!

Well this is far beyond cool but highly functional, a Quake like terminal implementation of Terminal.app that is a HotKey away from within any application. A friend turned me on to this after it showed up on the Monday morning Apple links post from arstechnica.com. Although I have never thought of this idea, it seems to have been a popular request for quite some time and after a public request, the author of QuickSilver stepped up to the challenge and coded this little goodie using the application enhancer method called SIMBL which was created by Mike Solomon, the creator of the PithHelmet plugin for Safari.

I have not been a black Mac owner since I got rid of my Lombard (aka the Bronze Keyboard) way back in 2001. Before that, I was the proud owner of a 3400c which was also black and one of the first PowerPC laptops offered from Apple. That PowerBook cost me close to $4,000 if memory serves and I swear some of the debt is still hanging around today! So after being with Apple for so long I have very glad that good Mac hardware has gotten cheaper over the past 4 years and to see the return of a the darker colored books. Its about time too and the price is just right.
