I work in a place where we use Concurrent Version System (we still use them :P) . We had our code base with us. We wanted to submit the entire code structure to CVS. It almost had 15 – 20 directories and each containing number of files in it. Instead of checking in the code folder by folder , we tried hitting it in a single shot.

It was an import command that i googled up. I tested in local .. It worked fine.. Then i issued the following command

    cvs import -m "message" code_dir rtag vtag

It got imported. We were happy with it.. But when we tried checking out the code, we found an interesting thing.. Code got checked in the wrong path. Apparently , CVS Import statement doesnt need a commit. It has an auto commit. We ended up in a mess.

Now, we wanted to delete the codes that we have checked in. But, The great CVS system wont allow the code directory to be deleted using a command. Atlast , we ended up with the following command which will erase all the files ( but the folders will remain as such ).

    cvs remove -Rf code_dir
    cvs commit

The directory skeleton remained till the end and we had to convince our admin regarding the trouble that we have created.

Summary : Analyse the negatives parts of the command before issuing it and be careful while using those systems where we don’t have admin rights.

Eclipse – Click Here

Tomcat – Click Here

Now follow the installation steps:

1. Lets open eclipse IDE. It will look like this.

Hi friends,

i just wanna share some difficulties that i faced when using browsers in my lap… I have Internet Explorer, mozilla, chrome  installed in my lap..First i used Internet explorer , all we know its a very slow one..it takes some seconds after the click to get opened.. but really the compatibility is good and ie 8 is much faster than the previous one.

Then i moved on to mozilla… i was having mozilla 3.6… and it worked quite well compared to ie.. managing the bookmarks and addons are very easy in mozilla..but i did an update 2 days before…i upgraded to mozilla 4.0 …its the big mistake i did..u know mozilla 4.0 doesnt support idm and few other add ons..i strucked a lot for downloading files from net…hey guys be aware while storing your passwords..for my lazyness i stored each n every password for the sites..at last someone hacked my gmail account..since my password was strong i recovered it back…so dont store passwords..

google chrome! relatively fast when compared to mozilla..one principle advantage is we can do the search easier as the default search engine is google. the download manager in google chrome is much faster when compared to mozilla and ie..But it too has a serious bug.. one is we cant close the window when download is going on … and if we are downloading a 100mb file and disconnectivity occurs when 22 mb is downloaded. . chrome ll show it as “file completed”…u cant resume the download.. u have to do from beginning..Hence dont download bigger files in google chrome.

Mozilla 3.6 worked better for me than any other browsers…if u have any opinion about this pls do comment!

As insisted by most of the sites it would be good if we include a symbol, a number with, characters in both upper and lower case while choosing passwords.

While searching for serial numbers and cracks by visiting several sites we are getting affected by virus. we have to be aware of google keywords to make the search efficient.Here is an easy way to search serial keys in google.

In the search bar type

“the name of the software” 94FBR

For example

“windows xp sp3” 94FBR

This type of search dramatically reduces the amount of fake sites that trick you.

Follow the following steps to change your ip

1. click start button
2. Go to control panel
3. click on network connections
4. Right click on “local area connection” and click on properties
5. Double click on “internet protocol(TCP/IP)” from general tab
6. Click on “use the following ip address” under general tab
7. Create your own ip address. Just type 1s and 2s no matter what it is.
8. Press tab. It should automatically fill up the subnet mask
9. hit ok
10. hit ok
Now you should be back to local area connection screen

11. Right click on “local area connection” and click on properties again
12. Go back to TCP/IP settings
13. This time select “obtain an ip address automatically”
14. Hit ok
15. Hit ok
16. You got a new ip address

Note: This only changes your dynamic IP address, not your ISP/IP address. If you plan on hacking a website with this trick be extremely careful, because if they try a little, they can trace it back

Searching for games, movies and applications in google eats a lot of time. Here is an easy way to perform search in google.
