I had a bunch of html files where a particular style sheet inclusion had to be removed from about 500 odd html files.

Knew this could be done through an sed script , but found a better one using perl from here.

export OLD_TEXT=’<link rel=\”stylesheet\” type=\”text\/css\” href=\”style.css\”>’

export NEW_TEXT=’some new text’

and use it in the perl command as follows.

perl -w -i -p -e “s/$OLD_TEXT/$NEW_TEXT/g” *.html

or use it against all .html files from the current directory using find and xargs

find . -name “*.html” | xargs -i perl -w -i -p -e “s/$OLD_TEXT/$NEW_TEXT/g” {}

Until I saw this post , I was sorely missing the duplicate tab for firefox. It was near the top of my most loved firefox extensions till firefox 2.x. The addons page for this extension said it does not support 3.5. Well, and then I learnt 3.5 has a built in duplicate tab feature.

Just press the ctrl key and hold the tab you want to duplicate, drag and drop it to the place/area you want the new duplicate tab to appear. And thats it!!..

Life is simple now

Collabnet has added a enhanced merge client to work on top of Eclipse and subclipse. While it replaces the existing merge client given by default in subclipse, it adds quite few features for the merge process.

Every body knows the pain surrounded in an svn merge. No matter how you do it, there’s always a “merge related bug” that props up post a merge. The intention of this client was to simplify the merge process in a wizard fashion. While it does so, a very important feature was done away with: the dry-run feature.

Instead, it expects you to go ahead with the merge type you choose to, and then preview the conflicts and results in the Merge Results view. There is a menu option a called “Undo Merge” given there to let you undo your actions. So all these are done post a actual merge but before you commit the changes back to the server tree.

I got little nervous and uninstalled the feature coz I wanted to preview my merge before i “actually do it”.  And then I bumped into this article on the new merge client, which clarifies the reasons for removing dry-run feature.

Happy merging

To play 3gp videos with audio using mplayer in Ubuntu Jaunty, add the following line to your /etc/apt/sources.list file

sudo wget http://www.medibuntu.org/sources.list.d/jaunty.list --output-document=/etc/apt/sources.list.d/medibuntu.list

You need the GPG key for medibuntu packages. Get it the following way.

sudo apt-get update

sudo apt-get install medibuntu-keyring

sudo apt-get update

now install the following packages

w32codecs mplayer mencoder amrnb amrwb

You should be able to hear the sound in mplayer now.

[UPDATE] As of now the latest update on jaunty for the kopete package, the problem is fixed in the version 4:4.2.2-0ubuntu2.

It seems Yahoo! is changing their protocols for client connection. Heard somewhere this is done to disallow 3rd party clients like pidgin and trillian access yahoo’s messenger service. On my Ubuntu Jaunty, this has not affected pidgin yet! (looks like it auto adjusted) , but for Kopete I had to override the server connection to cn.scs.msg.yahoo.com and now its working fine.

Got the workaround from here.

Kopete is the only yahoo client on linux, AFAIK that allows video chat. Not sure if anything else has surfaced up yet. Haven’t been able to use Gyache yet with my webcam.

This post has reported that the flex builder work on linux has been put on hold.  Noted Adobe techie has said “there is not enough requisition for the product to continue its development”

Well, that’s not a great news to hear.. considering the open sourced SDK of adobe flex,  good amount of interest was generated in the FOSS developer community. To help it revive again, use this link to vote on the adobe site.

From the current builder available on linux ,which is infact a eclipse plugin, the main feature I missed was, the design view in it. Hopefully, when the development continues design view is also ported to linux.

New in gmail labs allows you to preview your inbox when gmail is loading. Useful, if you have a little slow connection.

If you have been working with Eclipse 3.2 or 3.3 with flex builder 3, and if the upgrade to 3.4 broke the builder, try the following patch http://www.tekool.net/blog/2008/06/28/flex-builder-3-plugin-dont-work-with-eclipse-34/

Just download the patch from here unzip it somewhere on your desktop and copy the plugins content ( 2 jar files) to your eclipse’s plugins folder. If you have any existing files while copying good idea would be to take a backup before doing so.

Now restart eclipse with -clean option. Your flex builder should work as it used to before.
