[linux] Split it out

Ever wondered how to transfer a huge file across network without having to worry about disconnection in the middle of the transfer?

How about splitting it into pieces and transfer it piece by piece, that way you won't worry about your connection getting cut off all of a sudden. Then after you have transferred all the pieces, just put it back all together again.

Here's an example

You have a large file about 100mb that needs to be transferred to the other side of the globe

 

let's split it into 15m each until the size is consumed, by default the prefix of the file is x followed by some letters

 

to make the file pieces more descriptive let's specify a prefix

 

we can have numeric suffixes too

 

to restore the file, we use cat for this job

simple and easy :)

I found a fix to this problem, thanks to chantra of Debuntu

First, download the patch

wget http://www.debuntu.org/sites/www.debuntu.org/files/vmware-7.1-ubuntu10.10-patch-v2.tar_.gz

Extract and run it as root

tar -xzvf vmware-7.1-ubuntu10.10-patch.tar.gz
cd vmware-7.1-ubuntu10.10-patch
sudo ./apply_patch.sh

Then run VMWare again, the modules should compile this time.

[linux] It's TOP and more

I've been using top for checking processes for CPU and memory usage but there's even more user-friendly way to check it. Here comes htop.

htop is an interactive process viewer that is similiar to top but more, it's interactive, easier to understand and it has graphs.

 

To install on debian/ubuntu

sudo apt-get install htop

To install on CentOS/Fedora

yum install htop

[ubuntu] Use wicd instead of network-manager

Tired of entering your password every time Network Manager connects to a wireless/wired device on first boot?

Replace it with wicd :D

sudo apt-get install wicd

Then remove Network Manager

sudo apt-get remove network-manager

Restart your system and you're done.
