How do I find out what program / file is using 100 GB of space on my Hard drive? Once I find the problem how do I delete the specific files to increase GB of space?

Use OmniDiskSweeper
Once you find file, it can be deleted from within OmniDiskSweeper

My mac air says hard drive full and 90% is full of 'other' which I cant work out what 'other' is as i Have transferred most to my external hard drive

My mac air says hard drive full and 90% is full of 'other' which I cant work out what 'other' is as i Have transferred most to my external hard drive.
Do you know how I can tell how large each file is taking up and what my 'other' category could be?
thanks

Initial easy steps to gain disk space:
- Delete all files in the Downloads folder.
Empty the Trash.
- Start iPhoto.
Empty its trash.
Restart.
Backup:
Run a Time Machine (or other) backup since you are about to delete and move files and you may need to recover from any inadvertent mistakes or decisions. You will need one external hard drive for your Time Machine (or other) backup and a second if you plan to offload some files. (See suggestions for where to purchase hard drives at the end of this message.)

Deleting files:
Then use the free application OmniDiskSweeper http://www.omnigroup.com/more to explore your volume in descending order by size so you can attack the problem from the top down, deleting the largest unwanted files first. Delete with caution and do not delete any system files. Remember to empty the trash after trashing the files.
Additional reference on freeing disk space:
http://pondini.org/OSX/DiskSpace.html
Offloading files:
Consider moving some of the no-often-used large files or directories to an external disk. Use ODS again to find them. This will be at least your second hard drive. Your first one(s) is/are for your Time Machine (or other) backup(s). Do not offload files onto a Time Machine disk.
Format the second drive as Mac OS Extended (journaled). Using OWS to find large files/folders and copy them from the system drive to the external hard drive and delete them from your internal drive.
Then  > System Preferences > Time Machine > Options… > Remove the offload HD name from the exclusions list.
Now both your system disk and your external offload disk will be backed up onto your Time Machine disk.

What format should I use for Maxtor One Touch III external hard drive

I'm not sure if I'm on the right forum section, but hopefully you can help. I just got a Maxtor One Touch III external hard drive with the firewire 400/usb 2.0 port. I installed the cd and followed the manual and it told me to format it. I went to disk utility and went to the "erase" section, but now it wants me to choose the type of format: mac os extended (case-sensitive), mac os journaled, mac os (case-sensitive, journaled) and so on.... Can anyone tell me what those formats mean/do, and what is the best one to use? Thanks!

Case sensitive is really if you are using some old UNIX programs that you have brought the source over to OS X and compiled them. And the UNIX programs have to expect a case-sensitive file system.
I'm betting this isn't the case... or you'd know what a case sensitive file system is.
So go with HFS+ Journaled

VPN Questions... What program should I use?

I need to connect to a Watchguard Firebox X1000. The only program that I can find that might work is VPN Tracker. I just want to know what program everyone else uses to vpn and why. And if anyone else is in the same predicament as I.

Tracker. I just want to know what program everyone

It looks like the watchguard supports ipsec and pptp - so you ought to be able to use the built in client.
If you want to use ipsec and are behind NAT, you can go with vpntracker($) - if you aren't behind NAT you can probably use ipsecuritas(free).
As for what I use - I use windows built-in ipsec because NAT-T isn't broken in it (hint hint apple... and I refuse to pay what I consider to be too much for vpn tracker, which is mostly a GUI for raccoon (built in open source IPSEC tool). (of course vpn tracker did fix NAT-T with thier own kernel extension - so I would use it if it were less expensive...)

How do I find out what features are not useful in my Classifier?

How do I find out what features are not useful in my Classifier? I am trying to trim down the number of features to speed up the training of my data, I have about 3700 features. I have found the Filter Based Feature Selection Module and have not been successful
in using it. I have looked through all the examples and have not been able to find any examples using the module. Will the Filter Based Feature Selection Module help me to trim features. If so how do I use it?

One way to do this would be is to use a random forest classifier. Feature/variable importance can be obtained relatively easily with random forests.
Here is how you may do it in R.
> install.packages('randomForest') #install randomForest package in R if it is not already there
> library(randomForest) # reference the library
> data(mtcars) # load motor cars data that ships with
#train a random forest
> mtcars.rf <- randomForest(mpg ~ ., data=mtcars, ntree=1000,keep.forest=FALSE, importance=TRUE)
> importance(mtcars.rf)
> importance(mtcars.rf)
#You will see an output like below
%IncMSE IncNodePurity
cyl 16.168645 169.96741
disp 18.672188 260.08722
hp 17.584375 184.95007
drat 6.948743 63.54528
wt 17.818509 254.30347
qsec 4.772889 33.25546
vs 5.303058 24.39064
am 5.210181 17.36626
gear 4.619161 21.55450
carb 8.577037 28.46715
# or plot the importance as follows
> varImpPlot(mtcars.rf)
What this tells you is how important predictors/features/variables like horsepower(hp), weight(wt), no. of cylinders (cyl) is in predicting miles per gallon (mpg).
If you are wondering how the data looks like. Try this
head(mtcars) # gives first few lines of the data set.
mpg cyl disp  hp drat   wt ...
Mazda RX4     21.0   6  160 110 3.90 2.62 ...

Datsun 710    22.8   4  108  93 3.85 2.32 ...

How do I find out what filters I have used in an open document?

How do I find out what filters I have used in an open document? I have been playing around with several filters and do not remember what I have done. I would like to use this filter setting for another image.
Thanks

1) save as psd for reverting later if needed
2) Click on the filter closest to the bottom in the history panel.
3) Choose the filter from the filter menu that was listed in the history panel
4)See what settings are there then click cancel
5)Repeat for the next filter up on the history panel
Do all of this before creating more steps that could push those steps from the history panel or close the document or photoshop as the history panel will be cleared.
Disclaimer: Even though the settings should be in the filters that you used last, there is no guarantee especially if used again afterwards with a different setting.

The button on my Ipod Touch (the big one just below the screen) will not work when I press it. Nothing happens, when before it would wake my IPod out of sleep mode, and exit out of programs I was using. Now, no reactions. What should I do?

The button on my Ipod Touch (the big one just below the screen) will not work when I press it. Nothing happens, when before it would wake my IPod out of sleep mode, and exit out of programs I was using (ex. ITunes or Safari to main screen) . Now, no reactions. When I press the button, it appears to be more indented then it was before. What should I do? Do I need to get it fixed or replaced, or is this a problem I can fix on my own? Whatever it is, I really need some advice. Thanks in advance.

i received a ms publisher file what program can i use to open and edit

There is no program that can open Publisher files except Publisher. It doesn't matter whether you use Windows or a Mac, Publisher files must have Publisher.
Publisher does not have a Mac version so you will need Windows (and Publisher)

I don't have many files, or many large applications on my MacBook Pro. 13'' with a 320 gb hard drive. However, Activity Monitor says I'm using almost half of it. What can I do to clean out the hard drive and keep only the files that I actually use?

I'm curious if there's a "defragging" or "cleaning" service available from Apple that I can use to take back some of my hard drive space.

Here are some links with information and caveats.
