simple things
Ever wished for a search engine with a human element– with user comments and votes on each search result? How would you like it if it throws up top results from Google, Yahoo! and MSN? And how about making some money as you search the web? And some more when you vote and comment on a search result!! Well, Scour grants all your wishes. Wonder why it didn’t occur to folks at Google!!
The Social Search Engine
Well, it’s time to go Scour!
The GNU screen is a terminal multiplexor. It enables users to run a collection of multiple, independent shells within the terminal (no parent-child relationships, so each shell can run its own programs independently without “waiting” for its children to die). screen can be detached from its terminal, and later reattached to any other terminal, without losing any running programs. Here’s a short tutorial:
$screen launches shell #0 in the terminal.
Let’s run an application here to mark this shell, say irssi.
^a c launches shell #1 in the terminal.
In this shell let’s run the w3m browser: w3m google.com
^a c launches shell #2 in the terminal.
Here, I run a ping: ping yahoo.com
^a c launches shell #3 in the terminal.
Here we ‘ll do a simple file listing: ls -l
Another ^a c will launch shell #4, yet another will launch shell #5 and so on.
Now we can cycle through the open shells with ^a [SPACE], or go to a numbered shell with ^a num.
We can also give names to shells:
First go to shell #0: ^a 0.
Now give it a name: ^a A Type chat when it asks for a name.
Similarly assign names to shells 1, 2 and 3, say browser, ping and listing respectively.
Now do ^a “ to see a list of open shells, and move up and down between them with k and j respectively.
You can even detach the entire screen (with all its shells) from the terminal. Just do ^a d. Now type exit and logout of the terminal. The terminal is gone, but the programs are still running inside screen. Fire another terminal and type screen -r to reattach the screen with all its shells and programs intact. Shells inside a screen are terminated by the regular command exit.

And yet I say unto you, That even Solomon in all his glory was not arrayed like one of these.
Box.net widget enables bloggers to share files on their WordPress or Blogger blogs. You can upload/remove/rename/move files and folders right from the widget button, or even change the widget’s name ( mine is called “Downloads”). Visitors can download files and subscribe to RSS feed to receive updates about latest uploads. Files can be sorted by their name, type and date of upload.
The setup is fairly intuitive:
Happy file sharing.
The find utility can be used to create a searchable index of floppies, CDs and DVDs. Let’s say a CD by the name disk2 is mounted at /media/cdrom, then:
cd /media/cdrom && find -type f > disk2
will create a text file disk2 listing all the normal files in the CD one per line. We repeat this with all the disks in the cabinet, say disk3, disk4, disk5… diskXYZ. Now we ‘ll create .disks directory in our home and move the disk files into it:
mkdir ~/.disks && mv disk* ~/.disks
Henceforth we can use grep to search through .disks for filenames:
cd ~/.disks && grep -i abiword\*.deb *
This will list the name of each disk (like disk25) containing abiwordxyz.deb, and full path to the respective file. Now it’s as simple as popping disk25 into the drive and doing a
sudo dpkg -i /full/path/to/abiwordxyz.deb
to install abiword.
Note: Don’t forget to label the disks with a marker.
