Bluetooth Proximity Detection on OS X:
“One thing that I’ve been playing with off and on for some time is a small efficient little solution for handling basic Bluetooth proximity detection, specifically for being able to perform certain actions when a cell phone or other Bluetooth device is in range of my Powerbook.”

Great article, what a brilliant idea!
After much debate and talk Sun Microsystems finally released part of the java platform under the General Public License (GPL) . While much has been said about the GPL, I like its insistence that adaptations or improvements made to the code must be made available for no charge.
Components available today include the HotSpot V.M. and javac (the java compiler). I’m particularly looking forward to getting my hands dirty with the compiler. A large propoirtion of the code is set for release in early 2007, and should be buildable from source.
I’m genuinely excited by the move, but my foremost concern is that the platform remains consistent and doesn’t diverge too much though as the write once run anywhere nature of java is one of its best features.

I picked up this tip when I was beginning to work with Ruby on Rails and Subversion. I added the following alias to my .profile file
alias svnaddall=’svn status | grep “^\?” | awk “{print \$2}” | xargs svn add’
This command takes all files in the present directory and flags them to be added in the next commit. This saves adding each of the files one-by-one. You don’t just have to use the command for Rails either- use it for everything. I do!

The new screen shots for OS X 10.5 are looking pretty sweet, I cant wait for it to outdate Vista upon its release.
I have found X11 forwarding on the mac to be excellent, however there is one tip that I’d like to share.
I have used both the -X and -Y flags as arguments to the ssh command, and found -Y to be faster every time. So when using X11 forwarding on OS X remember to use:
ssh -Y adam@myserver.com
Like most people I often have to search for information on the internet. My search engine of choice has for a long time been Google (link), more often than not it finds what I need in fractions of a second. But having a list of possible sources is just one step in the research process. The next steps often include sorting through the various sources, discarding results that are irrelevant and deciding upon the bias of the author.
However, I think I may have come up with a solution that cuts down on my search time dramatically. If I ever need easily understandable information I head for wikipedia (link). It is mostly well written, and generally up to date- plus there are external links if I want to continue looking into the topic.
I still use google for searching for precise information, although if what I want is general information then wikipedia gets my vote!
