So your old laptop is a bit long in the tooth – working well but the hard disk space is all used up.
Here’s a few ways to get some extra space.

Remove all the extra language files to gain a few hundred MB.
1. Download Monolingual from here
2. Run it and it will remove all the language files you don’t need. It defaults to keeping english, gets rid of Afrikaans, Albanian, Amharic etc. (Don’t use the other features of monolingual – just the language removal.)

Use Disk Inventory to see where your space is being taken.
1. Download Disk Inventory X from here.
2. Run it, go have a cup of coffee – it can take a while.
3. Look at the results, they will be a picture like this:

You can mouse over the colors to see which files they are on the hard drive, and then manually delete the folders to create free space. I found lots of thinks I did not need with this program, like old movies hiding away, folders full of microsoft junk, etc. Don’t delete anything if you don’t know what it is though.

Clear out your Library/Application Support folder
Have a look in your Macintosh HD/Library/Application Support folder and there may be some old folders from applications you have deleted but no longer use. You can delete them.

Clear out your Printers
Have a look in Macintosh HD/Library/Printers and delete any folders for printers you don’t need. For example my Epson library contains 1.4G yet I don’t have an Epson printer!

To see how much space a folder takes, go to Menu ‘View/Show View options’ then select the box that says ‘calculate all sizes’.

1. Go to your utilities folder.
   (Click on your desktop anywhere so that the finder is active.
   Hold down apple-shift-U, this will open your ‘utilities folder.)
2. Open ‘Activity Monitor’
3. Press apple-1 so that the main window of Utility Monitor is open.
4. Click on the ‘System Memory’ tab at the bottom of the window. This will display a little pie graph of how much memory you are currently using.

There are two important items to take note of ‘Free:’ and ‘Page ins/outs:’

Free tells you how much free memory you currently have, the higher the better, and
Page ins/outs tells you how many times your computer has had to slow down because it has run out of memory and needed to use the hard disk to ’switch’ some of it’s memory in our out of use. This really slows down your computer.

If the page in/out count is increasing as you watch it, this is not good, it means your computer has run out of free memory, and so temporarily is using the hard disk as memory. The faster the page in/out count is increasing, the worse the problem – your computer is struggling along and not performing as well as it could. You need more memory.

If you have had lots of free memory since the last time you restarted your machine, the Page ins/outs count will be 0/0. This means your computer had enough memory and has not run out. You dont’ need more memory.

It may be that your Pagein/outs count is high, something like 50431/10850, but steady and this and not increasing. What this means is that some time in the past when you opened a lot of programs, you ran out of memory, but now you have enough. Reboot, check the Pagein/outs count again. It should be 0/0. If it is not 0/0, have a look at it while you open a program or two and see how fast it increases, the faster, the worse your system performance will be.

Here is a screen shot of my computer. My page in/out count is quite high – 66825/697, but I still have 189 MB free, and the page in/out count is not increasing at the moment. This means that sometime since the last reboot, my computer ran out of memory, but currently it is OK. If I reboot the page in/out count will return to 0/0, and stay there unless I go crazy opening lots of programs. I don’t’ need more memory.

To quote from apple:
Moving data from physical memory to disk is called paging out (or swapping out); moving data from disk to physical memory is called paging in (or swapping in)… Extended periods of paging activity reduce performance significantly; such activity is sometimes called disk thrashing.

One more note: Under Leopard rather than giving a ‘count’ of page in/outs, it gives a size in MB of the amount of RAM that has been pages in or out – the numbers are smaller but the same principals apply.

To submit your site to google go to:

http://www.google.com/addurl/

Add your web address, then wait a couple of days.

do the same for yahoo, msn etc

To see if google already knows about your site type site:http://www.yoursitename in google search

If you want your page to go up in the search results, you need to have other people link to your site from their site.

To see how many sites link to your site type link:http://www.yoursitename in google search.

The more entries here, the higher you will be in the search result, basically that’s a simplified version of how it works.

With so many different battery types, how do you know whether to recharge them or flatten them every time you use them, and does it matter?

It does matter. Some batteries can be damaged if you use them wrongly, others have a reduced life. Here’s a quick guide.

• Lithium Ion Batteries (Li-ion) are found in all new Apple laptops and ipods. They are also in digital cameras and mobile phones. The more you keep them charged the better. It’s best to never let them run out. They only last about 300 full discharges, so if you let them run totally flat you have used 1/300th of their life. It’s best to charge them as often as you can. Whenever you are not using them put them on the charger. Keep them cool while charging.
• NiCad batteries are exactly the opposite. It is best to let them run totally flat each time you use them. They are found in older cordless drills, older laptops and some cordless phones. If you recharge them before they are fully flat they will ‘remember’ where you discharged them to. So if you keep charging them when they are half empty, you’ll find they will stop working when they are half empty.
• NiMH batteries are like Nicad batteries but the ‘memory’ effect is not as bad. You should still discharge them fully but it won’t hurt them quite as much if you don’t. If you cant’ do it every time, try to fully flatten them occasionally.
• Car batteries (lead acid batteries – also in some camcorders) are the worst for being damaged when fully flat. Every time they go fully flat it does irreversible damage – 3 or 4 times and they will be totally wrecked. Like a lithium ion battery, it’s best to keep them as charged as fully you can.

This one is quite an advanced tip.
If you right-click on a file you get a little menu, and if you select ‘open with’ you get a list of all the programs you can open a file with.
After a while of installing new versions of programs, this list can become quite long!
To reset it open up a Terminal window. (from Applications/Utilities) and paste the following line:

/System/Library/Frameworks/ApplicationServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user

press return wait about 20 seconds, and your open with menu will be fixed.

I think this only works on 10.4 and it may reset some other things to, like what applications open certain files.

Due to limitations in the QuickTime Architecture, AVI video files containing MP3, WMA or AC3 audio tracks will not play directly in QuickTime based applications. You may experience stuttering, loss of sound, no sound or an error message.

We have written a useful application called “DivX Doctor II” which can fix these problems, and other issues QuickTime has with AVI files. You can download DivX Doctor II from http://doctor.3ivx.com/.
