Arduino: Problems With librxtxSerial.jnilib

Recently the Arduino IDE installation refused to start on my Mac with the following exception:

uncaught exception in main method: java.lang.UnsatisfiedLinkError: /Users/arun/arduino-0015/Arduio15.app/Contents/Resources/java/librxtxSerial.jnilib: no suitable image found. Did find: /Users/arun/arduino-0015/Arduino15.app/Contents/Resources/java/librxtxSerial.jnilib: no matching architecture in universal wrapper

Rather bizarre error and as far as I know, I hadn't mucked around with any settings. According to the Arduino forum it had something to with the Java version and suggested giving priority to Java 5 over Java 6. However this didn't work on my setup. Eventually I just downloaded the Java 6 compatible version of librxrxSerial.jnilib and replaced it in the package contents of the Arduino app. This fixed the problem.

To fix this, click on the Arduino application (e.g. Arduino 16.app) in the Finder, and select Get Info from the File menu. In the info panel, click the Open in 32 Bit Mode checkbox. You should then be able to launch Arduino normally. (from the arduino faq's)

FCC Aproves Sirius-XM Merger

This has been a long time coming but finally the FCC has finally approved the merger of Sirius Satellite Radio with XM Satellite Radio . The combined entity is pretty much a monopoly in the satellite radio space but they are still competing with terrestrial radio. Either way, their stocks, NASDAQ:SIRI and NASDAQ:XMSR should get a good boost on Monday. Yahoo! Finance Quote for SIRI Quote for XMSR

Lead Tide SIM Reader

I recently came across a cheap little device for reading SIM cards . It was available from Meritline for less than USD 5 with free shipping. Curious to see what it was like, I ordered one. The device came in a small package along with a mini CD containing drivers. The packaging advertised the device as the LEAD TIDE Sim reader . Like most things these days, it's made in China. The device has a USB 1.1 interface. There was no product code or number anywhere on the packaging. Installing the drivers for the device turned out to be harder than I expected. The mini CD's autorun installed some stuff but Microsoft Windows XP couldn't install any suitable driver for the device. The mini-CD had several top level directories with what appeared to be product codes but I couldn't match any to the device itself since it had no product code. Google searches revealed that I wasn't alone in my endeavors to get the device working . Further digging revealed pointers to some thir

Migrating from Palm Calendar to Google Calendar and iPhone

Here are the free steps to migrate from Palm's date book (or Pimlico's DateBk6 ) calendar to Google calendar for full iPhone sync. First, sync Palm with Palm Desktop . Next, open Palm Desktop, select the Calendar view, navigate to File | Export, select Export Type as Date Book Archive, Range as All and provide a file name. This will export the calendar data as Date Book Archive (.dba). There's a paid tool called DBA2CSV that converts .dba files to .csv files. However this can be done for free using Yahoo Calendar. Login into Yahoo Calendar and via Settings/Import, import the .dba file. It helps to have an empty Yahoo Calendar. Via Settings/Export, export the calendar as .csv file. Login to Google Calendar (also works with Google Apps For Your Domain GAFYD Calendar) and import the .csv file into any of the calendars. It is a good idea to create a test calendar and test the import before importing into your real calendar. That way if anything goes wrong, you can delet
