The extended File Allocation Table (exFAT) file system is the successor to FAT32. exFAT handles large files and external media greater than 32 GB. To install exFAT support on your Windows XP system go here: support.microsoft.com/kb/955704
Note: If you need a flash drive to transfer files between a Mac and a Windows system, then the exFAT format is currently your best option. The reason for this is that OS X does not natively support writing (i.e., read only) to a NTFS formatted volume. Also exFAT is the only Windows format supported by the OS X Disk Utility application.
MathWorks provides a noninteractive installer (aka silent installation) for MATLAB. This installer can save you time and prevent errors in environments where there are many installations to perform, and the information you need to enter for each installation is the same.
The steps for this are pretty simple:
- Edit the installer input text file (e.g., installer_input.txt) provided by MathWorks, changing the parameters as appropriate for your site.
- Place you license file in the folder pointed to by the licensePath parameter.
- From a Terminal window, cd to the MATLAB installer folder, and enter
./install -inputFile installer_input.txt
You can take this one step further by putting an Applescript frontend on the command-line installer. Bundle everything together in a zip archive or dmg disk image and you have a simple, easy to distribute, double-click installer.
Here is the Applescript (matlab-installer)
tell application "Finder" to get folder of (path to me) as Unicode text
set workingDir to POSIX path of result
tell application "Finder"
if (not (exists folder "/usr/local/bin")) then
do shell script "mkdir -p '/usr/local/bin' " with administrator privileges
tell application "Terminal"
do script "cd " & workingDir & "matlab_folder; ./install -inputFile installer_input.txt"
Assuming a folder tree like
As of Mountain Lion the X Window System (X11) is no longer included with OS X. To further develop and support X11 on OS X Apple created the XQuartz open-source project. You can download the latest version of XQuartz from:
The Quick Response Code (QR code) is a two-dimensional, machine-readable, barcode developed in the 1990′s for the auto industry. Apart from its application in things like inventory tracking, the QR code has become a popular way to add smartphone readable URLs to print materials.
Consider using it on posters, business cards, or documents when you want to direct your audience to web pages, data sets, movies and other content. Moreover, if you use a Googl URL you can easily track your page hits.
There are many sites on the web that will encode text to a downloadable QR code image file. Just search on QR code generator. The QR code above is the URL
ImageMagick® is a software suite for the manipulation of bitmap images. It can read and write images in 100+ formats and runs on Linux, Windows, Mac OS X, and other operating systems. ImageMagick is free and is distributed as binary applications or as source code under an Apache 2.0 license.
ImageMagick is typically run from the command line. On the Mac, embedding an ImageMagick command in Applescript is a great way to make droplets for specific tasks (e.g., make a thumbnail, adding a drop shadow). ImageMagick features can also be called from a variety of languages (e.g., Java, C, C++, PHP, Python, Perl).
The current release of ImageMagick is available from www.imagemagick.org/download. On OS X it can also be installed via MacPorts. The ImageMagick web site is www.imagemagick.org.
GNU GRUB (short for GNU GRand Unified Bootloader) is a Linux boot loader package from the good folks at the GNU Project. It is one option for creating dual- (or multi-) boot systems.
You can create a custom GRUB splash screen by replacing the image file splash.xpm.gz in /boot/grub/. This is a compressed XPM formatted file. Image constraints: 640×480, 16 colors (only 14 are available for your image). You may not know the XPM format. X PixMap was intended for X Window System icons. You can convert an image to the XPM format using GIMP or ImageMagick.
Xcode is Apple’s integrated development environment (IDE) for OS X and iOS. Its tool set includes: an editor, interface builder, project and source code managers, LLVM compiler for C, C++, & Objective-C, a debugger, and more.
Xcode can be installed from the App Store or downloaded from the Apple developer web site. Happy coding.
While it is best in most cases to update you Macintosh software via the App Store, you can download manual update installers from
This can be a useful option when, for example, you need to update multiple computers, but only want to download the update once.
Apple recently ( October 2013 ) released major updates of its iWorks application suite ( Pages, Numbers, Keynote ). In addition, Apple is offering free copies of the updated iWork apps to all current owners. iWorks is also free with the purchase of a new Mac.
Unfortunately the iWorks update was a major rewrite and Apple choose to drop a number of features. Apple is aware that this made a lot of people unhappy and says it will reintroduce many missing features within the next 6 months. For more info see

Perhaps the most notable thing about this release (v10.9) of Apple’s new version of OS X is that it is free. To upgrade, simply open the App Store and select the Mavericks install. The installation will take a couple of hours. Before you upgrade however be aware of the following caveats:
- The upgrade does an un-install of Java and X11. Both of which are needed for MatLab. After upgrading, if you use X11 or Java, you will need to re-install.
- Parallels v7.x and below does not work in Mavericks. Parallels v9.x is required for full support. Parallels v8 latest update will be able to open virtual machines, but won’t have the new integration features between Mavericks and Windows.
- Some people, myself included, have had problems with the Mail application. For example, Mail’s IMAP support is not playing nice with a number of mail servers (e.g., Gmail). Also the Mail app is routinely not quitting, requiring a force quit. [The "Mail Update for Mavericks 1.0", released November 9, seems to have fixed most of the Mail app's problems.]
