Positive Facebook Updates Get More Likes, Negative Get More Comments [INFOGRAPHIC]

Positive Facebook Updates Get More Likes, Negative Get More Comments [INFOGRAPHIC]:
Facebook users Like positive content way more than negative content, showing the world’s largest social network is not a space where the unhappy help each other slump further into depression.

This should come as no surprise, as many of our Facebook interactions mimic our real world social lives. More popular Facebook users (with higher friend counts) write longer status updates, use the second person “you,” talk about sex and use religious words. Less popular users are more negative and emotional, use the first person “I” and talk about family.

This Help for Depression infographic illustrates how we use Facebook to share our feelings. Its data is based on a study of 83 13-year-old girls’ communications habits, including Facebook, among other things.

Facebook users’ status updates are most positive between 6 to 7 a.m. and become progressively more negative as the day goes on. While positive updates receive more likes, negative updates receive more comments.

What type of content do you typically Like on Facebook? What do you comment on?

Google Acquires Metaweb to Improve Search

Google Acquires Metaweb to Improve Search: "

Google has acquired semantic web and real world database company Metaweb, a move the company says will help them “improve search and make the web richer and more meaningful for everyone.”
We wrote about Metaweb back in 2008 when they received a significant chunk of funding to the tune of $42 million, on top of their first round of $15 million back in 2006. Since then the company has built its Freebase open database into a collection of over 12 million items from entertainment (movies, books, TV shows) to locations, celebrities, companies and other “real world” objects. Google says the plan is to preserve and further develop the database and hope to enlist other companies to make use of and contribute to the data.
In addition to fleshing out Freebase, Google also hopes to leverage Metaweb to enhance its efforts with features like rich snippets and search answers, both of which aim to give back “smarter” and more immediate results to specific queries. Right now, simpler requests like “Barack Obama birthday” and “events in San Jose” can spawn relevant answers right at the top of the search results page, but Google hopes to take this initiative further by feeding in more facts about the real world from Metaweb’s data repository.
For an overview of what Metaweb has been working on, check out the video below. Let us know what you think: will this acquisition help Google deliver better search results?

How to configure file sharing in Windows XP

2009-12-23T20:34:00.000-08:00

I found this useful when I wanted to enable file sharing in Windows XP with total control.
Just by turning off "Simple File Sharing" will give you more control.

To turn Simple File Sharing on or off in Windows XP Professional, follow these steps:

1. Double-click My Computer on the desktop.
2. On the Tools menu, click Folder Options.
3. Click the View tab, and then select the Use Simple File Sharing (Recommended) check box to turn on Simple File Sharing. (Clear this check box to turn off this feature.)

If you are working with SSH to remote server over an VPN, you may have thought "Can I maintain sessions with SSH even when my connection goes down" as you might have had the bad experience of starting your work all over again... too bad. There is a solution for this... SCREEN, but that’s not all, it has lot of features that'll make your life easy if you are regularly working with SSH.

What is SCREEN

Screen is a full-screen window manager that multiplexes a physical terminal between several processes (In simple terms, it runs multiple terminals at the same time from single console login over ssh session).

The same way tabbed browsing revolutionized the web experience, GNU Screen can do the same for your experience in the command line. Instead of opening up several terminal instances on your desktop, Screen can do it better and simpler. Not only that, with GNU Screen, you can share sessions with others and detach/attach terminal sessions. It is a great tool for people who have to share working environments between work and home.

Feel like geek stuff... lets have a practical session to see how it can help us :)

Login to remote server over SSH

$ ssh me@myserver.com

Start screen session.

You can name your window/session (loadtst1 is name of session):

$ screen -S loadtst1

Let us run "top" command on first session or window (just an example).

$ top

Create new window in same session

Next you would like to do a load test on your new application (just an example, it may be download something from ftp/http site or any thing you wish to do in the remote machine) while you are monitoring the server by "top".

You need to create another screen window by pressing special key combination.

Press CTRL + a followed by c key (first hit CTRL+a, releases both keys and press c).

But how do I switch between these two tasks?

· Switching between windows is the specialty of screen utility. So to switch between "top" and loadtest window (or session) press CTRL+a followed by n key (first hit CTRL+a, releases both keys and press n).

· To list all windows use the command CTRL+a followed by " key (first hit CTRL+a, releases both keys and press " ).

· To switch to window by number use the command CTRL+a followed by window number (first hit CTRL+a, releases both keys and press the number of the window[0-9]).

Leaving Screen

There are two ways to get out of screen. The first is just like logging out of a shell.

You kill the window with "Ctrl-A" "K" or "exit" will work on some systems. This will kill the current windows.

If you have other windows, you will drop into one of those. If this is the last window, then you will exit screen.

The second way to leave screen is to detach from a windows. This method leaves the process running and simple closes the window.

If you have really long processes, you need to close your SSH program, you can detach from the window using "Ctrl-A" "d".

This will drop you into your shell. All screen windows are still there and you can re-attach to them later.

Attaching to Sessions

So you are using screen now and load testing that program. It is taking forever and suddenly your connection drops. Don't worry screen will keep the load testing going. Login to your system and use the screen listing tool to see what sessions are running:

[root@svr1~]# screen -ls

There are screens on:

26335.loadtst1 (Detached)

26403.loadtst2 (Detached)

2 Sockets in /var/run/screen/S-root.

[root@svr1 ~]#

Here you see I have two different screen sessions. To re-attach to a session, use the re-attach command

[root@svr1 ~]# screen -r 26335.loadtst1

Just use screen with the -r flag and the session name. You are now re-attached to the screen. A nice thing about this is you can re-attach from anywhere. If you are at work or a client’s office, you can use screen to start a job and then logout. When you get back to your office or home, you can login and get back to work.

Common screen commands

screen command	Task
Ctrl+a c	Create new window
Ctrl+a k	Kill the current window / session
Ctrl+a w	List all windows
Ctrl+a 0-9	Go to a window numbered 0 9, use Ctrl+a w to see number
Ctrl+a Ctrl+a	Toggle / switch between the current and previous window
Ctrl+a S	Split terminal horizontally into regions and press Ctrl+a c to create new window there
Ctrl+a :resize	Resize region
Ctrl+a :fit	*Fit screen size to new terminal size. You can also hit Ctrl+a F* for the the same task**
Ctrl+a :remove	*Remove / delete region. You can also hit Ctrl+a X* for the same taks**
Ctrl+a tab	Move to next region
Ctrl+a D (Shift-d)	Power detach and logout
Ctrl+a d	Detach but keep shell window open
Ctrl-a Ctrl-\	Quit screen
Ctrl-a ?	Display help screen i.e. display a list of commands

Working with PostGre

(I'm still writting this article, sorry for inconvenience)
I had a quite a different experience in working with PostGre as I was working with MySQL for so long and found some features in PostGre are quite interesting...

PostGre history

My experiences with PostGre

Examples

To dump a database:

$ pg_dump mydb > db.out

To reload this database:

$ psql -d database -f db.out

To dump a database called mydb to a tar file:

$ pg_dump -Ft mydb > db.tar

To reload this dump into an existing database called newdb:

$ pg_restore -d newdb db.tar
