What do the acronyms I18N or L10N stand for? What do they mean for developers of mobile applications in particular?

I hosted a session about localizing mobile applications at Developer Week 2014 in Nuremberg. It covers — among other things — text, numbers, date and time, images, and other localizable resources.

See the codecentric blog for slides and some more details.

The post and the slides are also available in German.

Over on the codecentric blog I published an article about localizing iOS and OS X applications called "Pseudolocalization for Cocoa Apps". It is probably the first of a few, because it turned out rather long already.

While I try to contain everything about installing MySQL in a single post that I update from time-to-time, Mac OS X, Mountain Lion (10.8.x), requires some pre-steps. You must install XCode, and the Command Line Tools. This post provides the screen shots and step-by-step instructions.

Before you can do any of these steps, you must connect to the Apple Store and download XCode. Dependent on your internet speed this may take some time. Generally, it’s an hour or less.

1. After installing XCode, click the Rocket Spaceship in the Mac Dock to launch a view of your Applications. Launch XCode by clicking on the hammer overlaying the blue background XCode icon shown below.

1. After launching …

This is about me getting a substantial amount of grey hair over the past couple of days, trying to hunt down a setting that would cause the current version of Xcode 4 to build my iOS projects to an unexpected, but not unfamiliar, taken over from Xcode 3, location, but not presenting any obvious way to revert that.


A little history
In Xcode3 you could use the preferences dialog to configure custom build output folders. This was necessary when you wanted to organize a somewhat more complex software into several cross-referencing Xcode projects and at the same time retain some sanity when linking and packaging it. Clint Harris Tutorial on shared libraries describes it in more detail.

The preferences dialog looked like this (image copied from Clint’s site, because I didn’t have any Xcode3 installation …

After my recent Mac OS X 10.7 Lion upgrade I was greeted with a dialog box after reboot telling me that
com.apple.dock.extra.xpc needs to take control of another process for debugging to continue. Type the name and password of a user in the "Developer Tools" group to allow this.
No problem, I thought, and entered my credentials. Alas, to no avail. My name and password were rejected, which had me a little panicked at first, because I thought the OS upgrade might somehow have botched my account, potentially locking me out of my Mac later.

Hitting cancel would only get rid of the message for a few seconds, then it would reappear, again and again.
Turns out the solution was quite easy: Go the Mac App Store and download Xcode 4.1. Once the installer has finished downloading, …

Drizzle 7 GA has been released, so I wanted to compile and test it on my Mac running OS X 10.6.7.  Since Drizzle 7 is new, Mac binaries are not available yet.  I’ve compiled MySQL from source more times than I can remember, and Drizzle was forked from MySQL, so I expected the build process to be similar and pain-free, and for the most part it was.  I did not use MacPorts or Homebrew for various reasons, mainly because I know that I will compile, tweak and recompile Drizzle often while hacking on it.  Also, the blog post  Drizzle in the Snow is about building Drizzle on Mac OS X, but it’s out of date …

I need to compile something and use the MySQL C++ library. I have mysql and mysql++ already compiled, I won’t go over how to do that now.

I added the following code to the top of my source:


#include <mysql++.h>


I got an error

/Users/jhaddad/dev/search_engine/main.cpp:4:21: error: mysql++.h: No such file or directory

Not cool.

How to fix:

In XCode, open up the project settings (under the project menu). Go down to search paths, and you can change your Header search paths to the correct locations where you installed whatever you’re looking for. In this case, mine was /usr/local/includes and /usr/local/mysql/

Next time you try to recompile, you’ll get a different error, this time it should be during Linking. Might look something like the below.
