Bash Completion on OS X


This is a issue fix quite often.. and its really annoying to get it right.
So… I am giving it a try to solve it once and for all, at least for myself.

Whenever I install a Mac for myself, I always use MacPorts ( for futher software (such as apache, ant, php ect). So I also use it for bash completion. The thing though is that the bash completion from MacPorts comes without any completions, or so it seems. So how do we get them working? Well… lets take it from the top.

Writing the XCode Cookbook

As some of you might know, I am writing an XCode Cookbook. This is a book which will contain only tutorials on how to do different things within XCode. So, no tutorials like “Adding Facebook to my iPhone app”, but more in the style like “Adding custom location to the iOS Simulator” or “Managing multiple targets within my project”.

I have a list of about 50-60 tutorials, but I need more. I need about 40 tutorials (3-4 chapters) more, so I am looking for tips; and since you, my readers, come here for such things, who better to ask but YOU!

MacPorts 2 & XCode 4.3

Well, to sum it up… this has been a “pain in the ass” for me. The last few days I have had some trouble running OS X 10.8 (Mountain Lion) preview… which is not that weird since it is a developers preview. The main problem was that MacPorts didn’t work since 10.8 uses Darwin 12 and Lion (with MacPorts 2 installation) uses Darwin 11.

So, I managed to screw things up so badly that I spend whole yesterday evening copying files manually to a USB drive using the “Install Disk” for Lion. Now I formatted my MacBook Air and Mac Mini and installed Lion once again.

Tool: Fix bootstrap server error when launching from xCode to iOS Simulator

Since the release of XCode 4.2 I have noticed a certain error poping up after buidling reguarly. The error incidcates that the iOS Simulator already has a process running or is hung. The anoying part is that even if you quit XCode and iOS Simulator, the problem wont go away.

This is the error:

Couldn’t register com.myApp.debug with the bootstrap server. Error: unknown error code. This generally means that another instance of this process was already running or is hung in the debugger.Program received signal: “SIGABRT”.

iOS 4 & iOS 5 tutorial: UIAlertView with link to WIFI or Settings app using Reachability and XCode 4.2


This tutorial is about how to make your apps UX just a little bit better. Have you ever noticed the message in google maps stating that if you activate Wifi you would get a better positioning? Or that when you want to send a text message and your phone is on flight mode, that you get the message to de-activate flight mode in order to send a text?

Well, it is actually really simple. These are just links that are opened. So, in this tutorial I will show you how to do this using e.g. Reachability.
