a plesant evening

What is trac ? Why trac? Many websites which use svn for maintaining their code are using trac to host their sites.

Trac is a web-based software project management and bug/issue tracking system emphasizing ease of use and low ceremony. It provides an integrated Wiki, an interface to version control systems, and a number convenient ways to stay on top of events and changes within a project.

I will keep it simple. http://trac.wordpress.org/ . One of the most popular open-source projects (wordpress) uses trac.

It took me a little bit of time for installing it. Had some problem with mysql with Trac ( installed v.0.10.4 ). Finally shifted to sqlite.

Now, its the time for configuring the webserver. As trac is written in python and by default, Apache does not have either mod_python module or Fast CGI installed(OS Specific) . I could not find the required rpms (rpm is the package manager for RedHat based OSes).

Installed mod_python and a little bit of configuration and viola ! its done ! The bad part is , a lot of time got wasted in searching for the rpms .

Now the svn repository . I had a repository in my old machine which contains some projects out of which yaat was one of them.

The problem now: One repos, require backup of 1particular project out of 8. Searched up in the svn redbook. But , turned out unlucky . There were only articles about how to take incremental backups and dump them back. After a little more googling , ended up lucky. This is the code snippet for creating a new repos from the old one along with the filter for filtering out based on the project name . svn rocks .

svnadmin create newrepos –fs-type fsfs
svnadmin dump repos | svndumpfilter include yaat | svnadmin load newrepos

If you dont give the fs type as fsfs, you may face some problem when hosting the site on trac. ( I got that problem, so I am not sure about it ).

`yaat` was my project name, repos was the old repository and newrepos is my new repository . Actually `yaat` here meant it searches(greps) for `yaat` in the list . And tadaaa. the porting of the projects done ! . But almost a day got eaten up because of this ! . Anyways if I want to install it again , I will end up facing less no.of problems than I had earlier .

Ans) Yes, you can. Just copy the image URI (URL) and paste it in where it asks for the filename in the File Popup Dialog box(the Qt style of viewing [painting] widgets) . I am not sure its the work of Windows(M$) File Dialog Widget or the Google Talk Application ( mostly Google’s ). Make sure the URI ends in one of the supported image formats (bmp, gif,jpg,png), else there can be problems.

This post can also be labeled as “Create Thumbnails using Google Talk” [ ] which looks a bit funny. btw, did you can see your display image in the URI http://mail.google.com/mail/photos/username@gmail.com .

So if you want thumbnails, upload an image, go to the above URI where you can find the photo in the thumbnailed size Who wants to save thumbnails this way anyways ? My guess , none !

Ques) Can I get a smaller thumbnail ?

Ans) Yes, add the arguments “?sml=1″ to the previously specified URI and you get the smaller image.
Ques) Can I get an image of size 100×100 when I resize using this

Ans) Probably, you cant. I am not the one who did it, ask Google ( search in Google ) . Try any of the online / web image editors ( Usually come in flash or js (for dynamic event handling and ajax) + serverside ( php or smth) . Adobe has recently released one , didnot check it out yet but, I am sure it rocks !

The next post I will be probably writing about how to know / identify blocked users in your Google Account ! interested ? Wait up then. I am not totally confident about the procedure . I will atleast post about my approach if I am not successful

I wanted to keep the post short

If you are un-happy or frustrated , try to

1. Think of things which make you happy ! really happy
2. Organize your data on your system in a good way so that when you take backup or delete stuff you can do it for the directories.
3. Organize your clothes,books etc.. in the real world.
4. Talk to people who dont talk topics which piss you off or talk to people who are really close to you.
5. Think about your life how it was age-5 to age-10 years ago ! (where age is your present age)
6. Design a webpage or hack one.
7. Try to know about XSS and find one in GMail.
8. Read comics / jokes.
9. Think of ideas and write them down.
10. Listen to rock songs in high volume, really high volume.
11. Drink hot coffee (works for me)
12. doze off
13. Try to hack some captcha ( try some image processing ).
14. Hack stuff !
15. get an argument with someone and kick him up bad ( dont get kicked up ).
16. If you want something really new , visit Wikipedia. ( wont work for me though ).

I wrote up this post so that it will be easy for me to refer what todo when I get the feeling.

There are two ways to save the image in Mozilla Firefox

1. Click Tools -> PageInfo and in the Media Tab you can find the images and click on the image and click “Save As..”
2. View the source of the page. Get the image location , copy the url and save the image.

Once one sees the source, one will findout that the contextmenu is being replaced. It looks something like

<img src="imagelocation.jpg" oncontextmenu="return false" />

If its possible for you to change this value in the contextmenu, you can directly get the right-click option enabled. Thinking about the post title, I should have named the title as “How to disable rightclick in Mozilla Firefox ?” . By the way, the code that works removing rightclick in imdb is

javascript:for(i=0;i<document.images.length;i++) if(document.images[i].oncontextmenu)document.images[i].oncontextmenu="";void(0)

in the Browser URL . and ta-daa you can right-click on the image. May be there is already a greasemonkey script available. I did not actually search for it.

Happy Hacking

IMDB[ http://www.imdb.com ]

Mozilla Firefox [ http://www.mozilla.com/en-US/products/firefox/ ]

GreaseMonkey [ http://www.greasespot.net/ ]

• Grease Monkey Script

I started out writing the greasemonkey script and then it suddenly struck to my mind

• Adblock Plus

Adblock Plus will do something related to my requirement . I just need to block the image from my view.As it is a gif , a transparent one, it wont  effect anything . Just right-click and block the image spaceball.gif and tadaaa.. you are done. From next time on, when ever you load a flickr page, you can directly save it with right-click and ‘Save Image As’ and you are done.

Assuming you are using Mozilla Firefox  and installed the plugin Adblock Plus

Just felt like having a gallery . Just wanted to try something different. Was browsing and found this site ( which is cool ) where in you can publish photos (on your website) with editing only one xml file or may be even without that.

Thank you Dileep , for lending me your camera.

Finally, could write one more post.

wrote up a new webpage/homepage , have to do some changes.. purely html,css,js only php for saving feedback ( someone tell me if I can do it in html )

btw, feedback section is working ! feedback is a must !

got a li’l  busywith some flashy thing will write about it soon .

In PHP you set the memory limit by

ini_set ( 'memory_limit' , '15M' ) ;

In Qt-3, if you wanna do some image manipulation the format will be something similar.

#include <qappliction.h>
#include <qimage.h>
int main ( int argc , char* argv[ ] ) {
    QImage srcimg("source.jpg");
    QImage dest;
    // Do operations on srcimg and save to dest
    dest.save("destimg.jpg","JPG");
}

and you are done. Qt is the best . A lucid reason is because of how the documentation is made and kept.
