Thanks to you for posting this. It helped me to resolve my issue by creating a function where I can pass the expression and values and function uses above logic and returns 1 or 0 based on expression evaluation.

Comment on Disabling Spotlight in OS X Leopard for the removable drives by gaetano

at wringley, instead of

for i in /Volumes/*;
do if [ "$i" != "/Volumes/Macintosh HD" ];
then shut_spotlight_for_volume “$i”;
fi;done;

I believe the following is safer
find /Volumes -user $USERNAME -maxdepth 1 -exec mdutil -E -i off ‘{}’ \;
where USERNAME= your user name

Comment on Sending and receiving GSM SMS on Blackberry using RIM APIs by Sudhakar Chavali

Thanks for sharing nice article

I have few questions that need clarification. Can you help me on this?
1. Do I need to mention port explicitly while creating connection object? I was reading a discussion in verizon developers forum where it was mentioned that I need to append port 0 to url.
Source: http://developer.verizon.com/forum/posts/list/645.page;jsessionid=B03609F47724D7EA6EFC3A54814EAE18#2109

2. what is the difference in sms://18001234567:9876 Vs sms://18001234567

3. (Sending SMS using RIM API) — Will this work both for CDMA and GSM devices?

4. When shall I use WMA way? Because Event Blackberry supports this API.

Thanks

Comment on Disabling Spotlight in OS X Leopard for the removable drives by Dick Guertin

I have an external disk drive partitioned into multiple volumes. Some are for backup use on Tiger, and some are for Leopard. Therefore, this drive is mounted to BOTH Tiger and Leopard systems, but “mdutil” on Tiger is expecting to find .Spotlight-V100/_IndexPolicy.plist, and Leopard is expecting .Spotlight-V100/Store-V1/VolumeConfig.plist, so you need to disable using each mdutil that comes with each system. Alternatively, as mentioned by “mozami”, you can:

cd /Volumes/your\ target\ volume
sudo touch .metadata_never_index

The existence of his file seems to be recognized by Spotlight on both Tiger and Leopard. But it doesn’t stop indexing in progress, and you can’t unmount while indexing is happening. So you need to stop indexing first with mdutil, and then add the .metadata_never_index file. At least then you can unmount the volumes (entire disk drive), and safely mount them of EITHER Tiger or Leopard. Also, you need to be concerned about your backup software. If you are making a “clone”, then .Spotlight-V100 on your boot volume will be copied to your backup, and you’ll undo the “disable Spotlight” work you did to prevent your backup from being indexed. Some backup software allows you to exclude certain directories (like .Spotlight-V100), yet retains what’s already on backup.

I’ve written a wrapper script that creates .metadata_never_index on my boot volume, does the clone backup, and then removes that file from my boot volume. That way, the backup software always copies .metadata_never_index to the backup volume, and prevents indexing the next time the backup volume is mounted.

Comment on Using HTTP-Over-Socket and HTTP Proxy in J2ME Applications by Nick

Alex32,

Depending on the phone and settings, most likely your Java apps go though WAP gateway when you use HTTP/HTTPS.

You should be very careful with socket connections if your data plan allows only unlimited browsing. The operator will charge you for internet access separately and it may be costly.

Opera mini is smart enough to figure out the best way to access Internet. However, if you really want to mess with the code, you can use JAD or another java decompiler to get the code from the class files. However, be prepared to deal with the code that has been obfuscated - i.e. it may be hard (or very hard ) to read and you may even have troubles compiling it back as is.

Hi! It seems very interesting and I have a question: I have an unlimited wap data plan from my carrier and I need to use a specific port and proxy to connect to the internet. And when I use java apps it always use the http protocol to connect. Socket protocol won’t work. Will opera mini connect through a proxy using socket protocol if I modify opera mini to implement this code.. If yes is there any doc where i can’t learn to know how to modify a .jar socket class? Thank you

If the only harddisk you want indexed is your main/internal harddisk, and that is called “Macintosh HD” you could disable indexing for all other harddisks replacing the last 3 lines in your script with

for i in /Volumes/*;
do if [ "$i" != "/Volumes/Macintosh HD" ];
then shut_spotlight_for_volume “$i”;
fi;done;

That way you don’t have to add the name of every friends usb pendrive when they quickly need something, etc.
