Cheapest Laptop Cooler - Water Packets

2008-11-19T03:44:00.000-08:00

Hi Folks -

The only problem with my Dell Latitude D630 laptop is while watching a movie. Over a period of time it starts getting warmer (it never hung though). This is probably common with all laptops, I've seen lenovos heat up faster and sometimes freeze too. So I started surfing for a good laptop cooler. While searching it occurred to me that most of them are USB based, which further draws another 5V from the laptop, i felt something was seriously wrong here. In the meanwhile my laptop was getting warmer again and seriously wanted to do something fast, i looked around and found a plastic bottle of water. I immediately put that under my laptop, and it actually started to cool off. Wow !

However it was a bit inconvenient to work with the bottle of water under the laptop. On surfing further for water cooler solutions, i found a guy used a 'hot water pack', filled with room temperature water and that worked for him. Thanks to him, I further thought of a more cheaper and efficient solution which will not incur any cost and more importantly can be made quickly.

The solution is - 'Water Packets' :-)

Here are the steps:

1. Find a decent and strong plastic packet, ideally 8" x 6" (l x b) and fill it with 35-40% of room temperature water.

2. Heat seal the packet with candle light, make sure you push unwanted air out as mush as possible.

3. Place that under your laptop's favorite hot spot. My laptops' hot spot is in the centre and bottom, which is where the water packet is now placed.

"Save the environment, make it green."
"Please don't purchase any plastic packet for this purpose, try using a disposed / discarded one."

Cheers
and Have Fun.

Freeing Space

2005-07-20T22:19:00.000-07:00

Found 2 utilities which did saved me lots of space:

- WinDirStat (from sourceforge) and downloaded from an alternate source
http://sf.gds.tuwien.ac.at/w/wi/windirstat/

- Check Identical Files v2.14
http://www.abc-view.com/cif.html

And just in case if you have cleaned up too much of your space, then download Ontrack DataRecovery 6.04 software :-)

Hard Links

2005-07-20T22:07:00.000-07:00

There is this guy who came asking on how do we search for hard links, i thought of initially writing a shell script, but then found out that our dear old unix 'find' did that job.

find . -name '*.c' -printf "%n:%i:%p \n"

(or just do a)

find . -name '*.c' -ls

%n - tells the number of hard links
%i - gives u the inode number
%p - the filename
