11.HTTPS Everywhere

This Firefox add-on encrypts all your communication with many major websites. As many sites support HTTPS, they still might use HTTP. Or they fill encrypted pages with links that go back to unencrypted sites. The HTTPS Everywhere add-on fixes these problems by rewriting all requests to HTTPS.

The Web Developer Checklist is a simple add-on that gives you an overview of the usability of your site.

16.Platypus

Hands down, Platypus is one of the best Firefox extensions for modifying a web page. It works with Greasemonkey as a sort of WYSIWYG and it will remember your edits when you visit the web page again. You can use it to experiment with different variations of a web design.

List of 5 Common Problems in CVS – Troubleshooting Guide

• Problem 1:- How will we modify our conflict occurred files ?

While updating if you will get message like bellow, then check,

This will list:

* “A filename” for files that you added
* “M filename” for files that you modified
* “C filename” for files that have conflicts

Conflicts are files that you modified and that were modified on the head revision as well.

@ If u ll get C or conflict then go to that file and remove that lines and duplicate line then it will recover, it because, if more than two developer working on same file and comming on same time then conflict occures,

Files with conflicts will have conflict markers in them. Conflict markers look like:

<<<<<<< filename
your lines
=======
other person’s lines
>>>>>>> current version

• Problem 2:-

If you are using your colleague’s checked out code for some changes, after that If you made any changes in code and then if you will try to check-in the code in CVS from your machine,after that if  it will ask your colleague’s password for checking-in. So How will we resolve this one ?

Soln:-
Please fine the CVS dir on your present code directory, then go to CVS dirctory, there, you will find Entries, Root, Repository like files , So now open that Rot file and change that username then your problem will solve, else let me know.
Steps:
cd CVS
vim Root
edit present urername to your username
@cvs:
:wq   // save and quit
cd ..  // come to parent directory
then do your work ..
it will fine

• Problem 3:-
  Is there any way to identify the information of deleted lines in a file through CVS annotate or any other means?

Soln:-

         You deleted from CVS or local server ? if u deleted from both server then i have to see, else if u deleted from      either local server or CVS server  then do “cvs -q up -Pd  “

else do “ cvs -q up -Pd -r  ” .

•  Problem4:-

           When I view the “cvs log”, the log report is fetching the file but says

            “date: 2008/12/31 06:00:51;  author: amareshcd;  state: Exp;  lines: +0 -0”
But I have added with 130 lines. Why the log is not showing “+130 -0” in its report.   ?

Soln:-

Use ,“cvs log -d date1 logfile.log”

•  Problem5:-

        I have files that went into the Attic.  How do I restore them back? Viewing  the files  revealed that they’re in DEAD State. Someone has ‘cvs remove’d the files. Just restore them with ‘cvs add’. How ?
