Facebook has a built in chat engine which allows users to chat through their browser window. Using chat from a browser window is not always easy. The Facebook chat box makes this particularly hard too. It is easier to chat using a dedicated IM client. In a previous post I had talked about pidgin – a free IM client with support for multiple accounts.
The best part about pidgin is that it will allow you to converge your friends accounts into a single icon on the GUI. that is you can combine a friends GTalk and Yahoo ids to a single name on pidgin. If the user is online is any one account your IM will message automatically to that id. This does not mean you can cross chat from Yahoo to GTalk or vice versa.
Although Pidgin supports Myspace there is no built in support for FaceBook chat. but that’s not going to let you down, because there is a wonderful plugin available solely for that purpose. The pidgin-facebookchat plugin developed under Google code and distributed under GNU GPLv3 can let you use FaceBook chat on Pidgin. The plugin is available for both Windows and Linux.
After installing the plugin goto “Accounts>>Manage Accounts>>Add” From the dropdown select Facebook as the protocol. Set you <username> and <password> of your Facebook account. You can set additional options including email notifications and Status updates from Pidgin under the Advanced tab.
Last day when coming back to edit my blog (http://www.exnol.com ) I was literally shocked to find out that the login page took ages to load. Thinking that it was a server issue because I had been here a few hours before, I came to face the reality the hard way. The problem was that the landing page or the front page or the index page of the blog was alright without any problems but every other page including the admin pages took many minutes to load, sometimes even dropping the connection.
So what should we do on such situations? After a brief search on Google and coming out with no practical answers I decided to go my own way. The steps : Since the front page was OK it was not a Database or Server issue. To make this sure I tried FTP using Filezilla and found out that FTP was fine. Since the admin interface was affected I couldn’t try deactivating plugins altogether. so I decided to try a trick. Rename the “plugin” folder.
Note the path to the folder : /wp-content/plugins
Right click on the folder and select Rename. Rename it with some other thing. You would successfully have brought down your WP blog now. Most probably your blog won’t work. (Make sure you try to access your blog at least once after the renaming). But hey its just temporary. Rename the folder back to plugins. Now you will have all of your plugins deactivated.
Now start reactivating plugins one at a time or in groups and watch which plugin is causing the trouble. This was my idea of the last minute trick you can use to deactivate plugins if the admin pages are unavailable. Share your thoughts!
The WordPress community like any OpenSource project has got a highly creative and devout developer base. They never fail to please you with every major release of WP. So the customizable dashboard was also no surprise. But the fact that we can use some applets on the dashboard as makeshift feed reader is what really impressed me. If you have a self hosted WP blog, you should probably have noticed this, or may be you don’t. So here is how you can view feeds on your WP dashboard.
You can use two of WordPress applets as feed reader which will show you the title with the first few sentences from a feed. The third one is much limited. This is made from the “Incoming Links” applet and so it shows only the first few words of the posts and the link. The two applets that can be used to view latest feeds as excerpts are titled “Other WordPress News” and “WordPress Development Blog”. When you move your mouse over the Title Bar of these applets you can see a configure link.
Click on that ad you will be taken to a page where you can set options for that particular applet. The config options include number of posts to be shown from that feed, Address of the feed, Title of the feed and some minor tweaks. I have added this blogs feed to the applet to show you how its is done. Once you have set these options you ca save them and configure the other applet. Coming to the third applet which is a little less mighty, things ecome somewhat different. We cannot edit the title of this applet directly from the dashboard (although we can do it by editing WP core file). You can just edit the address of the feed and the number of posts to be shown.
If you would like to keep the original applet feeds, make sure you save the feed addresses before changing them. You can use these applets to subscribe to two blogs which you can never miss out on. Although this can’t be substituted for a regular feed reader this would be fun tweaking.
Disk Usage Analyser(DUA) is a GNome ustility available for Linux. As the name indicates DUA scans the filesystem and finds out how much space is occupied by each directory and file. It then shows the usage along side a folder tree as a bar graph.When you click on a directory name, memory usage by each subfolder and files can be seen as an arc diagram on the right pane.
The Disk Usage Analyzer can be used to find out which directory or file uses how much space. It can be very helpful if you are trying to clean-up some Hard Disk Space from your PC. A similar tool for Windows is WinDIrStat at Sourceforge.net. but this one is a little less visaully attractive one. For KDE users KDirStat might be a solution.
Firefox has been long speculated to be one of the most stable browsers. On Windows I also believe this is true. But since running Ubuntu and Firefox for the past few months, I have to believe otherwise. Crashing Firefox has been a daily scene for me. Firefox gets hung even while loading GMail. This is not my problem alone. My friend who has got a completely different configuration has got the same problem. Here is a screen shot.
On Ubuntu Opera seems to be more stable than Firefox. But under Windows both are equally stable. For Firefox the problem has been almost solved by version 3.0.5 which we are running now. If you have faced a similar problem please comment specifying it.
In the last post we saw how to correct the aspect ratio of a video. Here is how you can edit an image to its correct sizes using GNU Image Manipulation Program (GIMP). For this I first reduced the image height. And that’s why it is seen as stretched. Now lets see how we can correct this.
1. Open the image in GIMP
2. Goto Image»Scale Image
3. Click on the Keep Aspect ratio Button (the small chain like icon next to the pixel box)
4. Change one of the dimensions (either height or width) to make the image to have a sensible shape
5. Save it.
The video is a screen cast of me doing the above procedure with an image of my favorite bike.
Many a people still don’t understand what the correct aspect ratio of an image or a video is. It is the correct ratio between its width and height which will make the image look normal to the eyes and not like a print on a stretched balloon.
Wrong aspect ratio
Correct aspect ratio
How do you correct if a video has wrong aspect ratio.
If the aspect ratio of a video is not correct then play it in VLC media player. Goto full screen mode and press “A” on the keyboard. This will change the aspect ratio. Repeatedly press the key until the aspect ratio is OK. Alternatively you can right click the screen and goto Video>>Aspect Ratio and select an aspect ratio from the list.
o adjust the aspect ratio of an image could be done using more than one tool. I will explain this in a later post.
