Don’t Search… Just Stumble!!! A new promising way to discover
Thanks to StumbleUpon.com for bringing in lot of visitors to my blog site in the recent past; which made me write this post 
In recent weeks, I have been watching a steady increase in the number of referrers being sent from the site StumbleUpon. Moreover I got similar referral hits on my other site ExpertsHeaven.com. Initially I was under the assumption that StumbleUpon is some kind of SPAM site and sucking my bandwidth (Even I was thinking to ban the site IP :(). Lucky I didn’t do so since I really learned what StumbleUpon is…!! Hence I though to write about StumbleUpon, so that webmasters and other can be kept informed about the traffic and usage as well!!

Learn how you can tweak your Firefox application to consume less memory and work little faster.
I’m crazy about this browser right from the day of release. Firefox bought me in a change of browsing style. I really love this tool. But only concern I’ve about Firefox is its memory usage. Hope this would be the concern for other users as well as the Firefox developers. It sucks most of the memory space. I’d say Firefox is memory ravenous compared with IE.
Firefox has lot of memory leaks and that has been fixed the most in the latest release. Anyway that’s not our part Mozilla developers will take of that If you think you can contribute better then join their team. Visit Mozilla today to find out more ways to contribute.

If you’re a freak who work around with Oracle as backend, you would face the sitution where the oracle temporary space would be exhausted.
The usage temporary tablespace can’t be found out exactly using DBA_FREE_SPACE. To find out the true value of temporary table space we may need to use V$TEMP_SPACE_HEADER data dictonary.
SELECT tablespace_name, SUM(bytes_used), SUM(bytes_free)
FROM V$temp_space_header
GROUP BY tablespace_name;

YouOS is a kind of web-based operating system. Web-based OS is still at the idea level and YouOs is still in its Alpha stage.
I came across this site recently. YouOS is an experiment in a new kind of computing platform. YouOS allows you to run a virtual computer through a web browser. YouOS keeps your data saved and when you log back in again the ‘computer’ is the same as you left it. It’s a platform for web application development that’s hosted online with an online IDE and online execution. All the apps in there run in JavaScript with AJAX. Developing YouOS apps are quite simple. With YouOS you can run small applications like sticky notes or clocks; Large applications like word processing, mp3 players, and instant messaging. Even better, it’s very easy to tweak an existing application or write your own. Read their manifesto here.

if you’re wondering why particular query or procedure is talking a long such a long time to run; then make sure you check out whether the object you’re accessing is locked or not.
there are quite a few dba views available to make our task less complicated. you can use the below query which will return you the list of locked objects.
SELECT
c.owner,
c.object_name,
c.object_type,
b.sid,
b.serial#,
b.status,
b.osuser,
b.machine
FROM
v$locked_object a ,
v$session b,
dba_objects c
WHERE
b.sid = a.session_id
AND
a.object_id = c.object_id;
you can now decide whether to kill the job/ process or someother roundaway to remove the lock obtained on the particular object.

Partition Table Doctor is a tool for managing Partition tables. Partition Table Doctor is effective when it comes to Partition recovery and hard disk data recovery. This tool was great help for me when I was struggling with Partition errors.
It was a wretched night for me; I was under assumption that entire thing got ruined for a minute. Yes, all the logical hard drivers I’d in my system had gone away after an illegal system shutdown. This was not new to me it has happened in past several times but mostly on the secondary hard disk which I don’t use anymore. I was totally astonished when the error occurred in my primary hard disk. It was horrible experience since I didn’t have a backup on the data, which I had in my primary drive
I tried few basic troubleshooting steps; but nothing seemed to work. So I started searching for a good solution for recover my logical partition. Finally this tool Partition Table Doctor stopped me. Partition Table Doctor sounded promising to me and I decided to give a try.
