Install Mail Notification

Installing something can’t be simpler. Just use the following command as root

[root@fedora ~]$ yum install mail-notification

Configuring mail-notification is very simple. Its as easy as it can get but there are tricks for special cases like Gmail for  Google Apps hosted websites.

Launch Mail Notification

Mail notification loses a point here. It doesn’t show up in any of the menus. You have to launch it from command line. You can launch mail-notification from System -> Preferences -> Mail Notification (Thanks mbooth for correcting). Or use the following command as normal user to launch mail notification

[saini@fedora ~]$ mail-notification -p

Configure Status Icon Behaviour

On mail notification properties windows, select Status Icon tab and choose the appropriate behaviour.

New Message Popup Settings

Now go to Message Popups tab, and select appropriate options. If you don’t enable popups, using mail notification doesn’t really make sense (though none can prevent you from doing so ). Keeping popus stacked is good because it shows you all messages in case you get more than one new mails in an interval. Also, you can configure the expiration time for the popups.

Add New Mailbox

Now select General tab and click of Add button. Mail-notification supports checking new mails from Evolution, Gmail, Yahoo! Mail, Windows Live Mail, any IMAP and POP3 Server and moreover your system mailbox Select Gmail for mailbox type. Enter username and password for Gmail account.

Now move over to Details tab and set delay between checking mails. I keep it 10 seconds

Add a Google Apps Hosted Email Account

This is totally optional Now we’ll add a Google Apps hosted account. This is a bit tricky. For mailbox type, you’ll have to select Gmail. For username, you’ll have to provide your email address.

Also, the mailbox name has to be modified in this case to make things work. Move over to Details tab and change mailbox name to your email address.

Add a new IMAP mailbox (Gmail)

This is totally optional Keep mailbox type as IMAP. IMAP Server has to be imap.gmail.com . Username and password are same as Gmail Account.

Note: For this mailbox to work, you’ll have to enable IMAP in settings tab in Gmail.

Now move over to Connection tab. Connection for Gmail IMAP has to be SSL enabled. So, select “SSL/TLS on separate port” and make sure the port number is 993.

Well thats all you need to do for configuring things for getting new mail notifications lightning fast Now sit back and relax until someone sends you a mail

The only major disadvantage that I found with mail-notification is that it doesn’t stay in notification area all the time. It appears only when there is a new mail.

Hardware Used

Graphics Card: ATI Radeon HD 3200 (256MB, onboard)
Monitor 0: ViewSonic VG1930WM 1440×900 (19″ LCD, Connected via DVI port)
Monitor 1: Samsung SyncMaster 793S 1280×1024 (17″ CRT, Connected via VGA port)

Types of Dual Display

• Mirror: Both screens have same content, identical refresh rate and resolution.
• Clone: Both screens have same content but refresh rates and resolutions can be different.
• Horizontal: Both screens can have different content, refresh rates and resolution. Screen 1 is left or right of Screen2.
• Vertical: Same as horizontal. The only difference is that Screen1 is above or below Screen2.

In this post, we are interested in Horizontal setup with xinerama on. This way we can have two desktops allowing full screen modes on both of them and allowing us to drag and drop windows from one screen to the other.

Install ATI Drivers

If you don’t have ATI drivers installed already, follow this How To: Install ATI Catalyst (fglrx) Drivers on Fedora 11 (works for any version of ATI Catalyst drivers).

Generate xorg.conf file

If you don’t see the xorg.conf file at /etc/X11/xorg.conf, then you need to generate it to proceed to next step. Use the following command as root to generate one

[root@fedora ~]$ Xorg -configure

This command will generate the default xorg.conf file at /root/xorg.conf.new. Copy it to /etc/X11/xorg.conf.

[root@fedora ~]$ cp /root/xorg.conf.new /etc/X11/xorg.conf

Backup xorg.conf file

Backup your original xorg.conf file so that you can restore it in case the configuration doesn’t work the way you expected.

[root@fedora ~]$ cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

Generate Configuration for Dual Display

Now we are ready to generate the configuration for dual display. Use the following command with appropriate arguments (in accordance with your hardware configuration)

# --screen-layout will place second screen on left of your first screen. Other possible values are right,above,below.
# --xinerama=on option enables you to have two different desktops and one of them being passive.
# You can drag and drop windows from one desktop to the other. Task bars appear only on one of the desktops.
[root@fedora ~]$ aticonfig --initial=dual-head --screen-layout=left --xinerama=on
# --resolution=_screen_number_,widthxheight
[root@fedora ~]$ aticonfig --resolution=0,1440x900 --resolution=1,1280x1024
# Set horizontal sync and vertical refresh rates for both monitors.
[root@fedora ~]$ aticonfig --hsync=0,30-60 --hsync=1,30-60 --vrefresh=0,30-60 --vrefresh=1,30-60

You can download my xorg.conf file via this link.

Reboot or Logout and Login Again

If you just setup your ATI drivers and configured the dual display, you need to reboot so that fglrx module can be loaded properly. If you rebooted after setting up the drivers, just logout and login again to checkout your dual display If everything works fine, say thanks to me and if not blame ATI

Adjust DPI for Normal Font Size

I faced a problem with my font sizes being too big while using xinerama. It was easy to fix by adjusting DPI. Go to System -> Preferences -> Appearance. Go to Fonts tab. Click Details located near the bottom right corner. On that window, try descreasing the “Dots Per Inch” value. Mine worked fine with 85 DPI.

Below is an image of my dual display setup. Click to enlarge.

A few days back I was designing the new logo for Videocache in Inkscape. After finishing the design, I saved the svg file carefully. And deleted other images which I embedded in the logo. A few moments later I realized that I just screwed up myself by deleting all those files as the svg file is now good for nothing.

I searched a lot on recovering files in Linux but in vain. Then a friend (bitgeek) told me about Photorec. I managed to recover all the files using photorec. I thought it would be a good idea to let others know and spread a good word about Photorec. Below is a step by step howto on using Photorec to recover your files.

What is Photorec?

From Photorec website,

PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from Hard Disks and CDRom and lost pictures (thus, its ‘Photo Recovery’ name) from digital camera memory. PhotoRec ignores the filesystem and goes after the underlying data, so it will still work even if your media’s filesystem has been severely damaged or re-formatted.

For This HowTo

Lets say I had a file download_arrow.png in /home/saini/Desktop which I have removed accidentally. Login as root and create a directory recover which will be used to store all the recovered files.

Install testdisk/PhotoRec

Photorec comes as a part of testdisk package in Fedora (I hope its same for other distributions as well). Use yum to install testdisk.

[root@fedora-tips ~]$ yum install testdisk

Launch Photorec

Once you are done with installation. Open a terminal and launch photorec (as root).

[root@fedora-tips recover]$ photorec

Select Hard Disk

If you have more than one hard disk in your system, select the one from which you have deleted the file(s).

Select Partition Type

If your hard disk has Linux partitions, then select [Intel].

Select Filetype Option

Move to [File Opt] and press enter. Here you can disable all file types by pressing ‘s’ . Use space to toggle the check button. Now since we removed a png file, we are going to check only png file type.

Select Options

Photorec also has a list of different options. Under normal circumstances you don’t need to modify them

Select Partition

Move the selector to the partition from which you have removed the file. Then press enter on search.

Select Filesystem Type

If you are using Linux, its going to be ext2/ext3/ext4. So the default selection is file.

Select Space for Analysis

Select free if you didn’t write to that partition after removing the particular file otherwise select whole.

Select a Directory to Recover Files

Now select the path where the recovered files will be stored. Then press ‘Y’.

Recovery Progress

Photorec will show how many files it has recovered.

All recovered file will be stored in the directory selected above. Open them in a file browser and you’ll get the removed file there. I hope this howto will help you recovering files you accidentally delete

I wonder why MSN would crawler same page from two different machines. I wonder if a single page can be divided further for crawling. Checkout the screenshots below

A few minutes later. Three Microsoft machines were crawling the same page

I have conformed using ARIN that all these IPs belong to Microsoft

[project@bordeaux youtube_cache]$ git push --all ssh://kulbirsaini@fedorapeople.org/~kulbirsaini/public_git/youtube_cache.git
Enter passphrase for key '/home2/Studies/project/.ssh/id_rsa':
ssh_control_listener bind(): Permission denied
fatal: The remote end hung up unexpectedly
error: failed to push to 'ssh://kulbirsaini@fedorapeople.org/~kulbirsaini/public_git/youtube_cache.git'
[project@bordeaux youtube_cache]$

Well, I couldn’t understand the error and jumped to #fedora-admin. I pasted the error on pastebin. Almost a minute laster, while trying to conquer the error, I Googled the exact error and I was damn surprised to see the paste as first result. What an indexing speed Google has??? See the screen shot for proof

In #fedora-admin ricky confirmed that nothing was wrong on server side and it should be a local problem with my machine or proxy server at my insti border. A few minutes later, I reliazed the /tmp/ permission thing and changing permissions back to 0777 fixed everything

1. Tabbed Interface

The tabbed interface for different utilities like mail, calendar, contacts, tasks etc. looks pretty clean. The interface is not at all cluttered in any way and navigation to different utilities is straight forward. You don’t have to brainstorm before getting something done.

2. Familiar Interface & Crisp Icon Set

Spicebird has an interface similar to loads of mozilla based application out there. The settings, preferences and the way things have been managed are familiar. So people who are switching from other open source email clients will not face any problems at all. Spicebird uses icons from Tango Project. The icons used are really good looking.

3. Nice Home Tab

The way Home tab has been organized is really appealing. You can add applets which includes rss feeds from you favourite blogs, mail folder views, calendar, upcoming events and Date & Time. Geeks love rss feeds. And what can be better than having it on your home tab all the time along with your mails. Event applet comes handy to remind you of the upcoming meetings and deadlines. And its on home tab all the time Date & Time is specially helpful when you collaborate with people in different timezones. So you can add their timezone on home tab and you know when is the right time to ping them.

4. Email

Email experience is more or less like any other open source email client. But Spicebird provides some intitutive features like if it finds that the content of a mail is about a meeting, it’ll give an option for creating a calendar event for the same. This is a really good feature and this is just the begining. Spicebird is still beta.

5. Instant Messaging

This is a really cool feature from collaboration point of view and which makes Spicebird different from the masses. Spicebird is supporting IM via any jabber server. So if you are a startup, setup your own jabber server on Intranet and use it for collaboration. Mind blowing!! This also includes Gmail/GTalk. So you can just say bye bye to your messenger and start using it right away with GTalk. Plus this will import all your contacts to your local address book. Another real good feature which is not there in lot of other email clients.

6. Calendar & Task Management

Another good feature. Integrated calendar and task management. You can quickly add tasks and events. And you need not check your calendar for upcoming events, add upcoming event applet on home tab and you will have them all the time in front of your eyes

Conclusion

Whether you are a startup which is looking for tools to collaborate or a user who is excited about using open source tools, just go and download Spicebird from here and explore a new way of managing things at a single place

You can look at Spicebird Roadmap here and checkout the video demo of Spicebird here.

Step 1:

Get the KDE4 rpms from rpmfind.net . Here is the list of all the kde4 rpms that you need to download from rpmfind.net.

Step 2:

Enable the fedora development repository. In '/etc/yum.repos.d/fedora-development.repo' file check if enabled is equal to 1 for development repo. If its zero, then change it to 1.

Step 3:

Use yum to install the kde rpms that you have downloaded.

[root@bordeaux KDE4_RPMS]# yum install *.rpm [Enter]  (do as root)

Note: After the KDE4 rpms are up in the fedora repos, then you can skip the step 1 and directly install kde by issuing the command

[root@bordeaux saini]# yum install kde* [Enter] (do as root)

My Experience

I was expecting a lot from KDE4. But a lot of things went wrong. When I logged into KDE4 for the first time, everything was looking awesome and very sharp. But then I faced the first crash while editing the settings for a widget and I realized that its not possible to have a crash free KDE application. After upgrade ( which cost me around 1GB of downloading via yum) and spending a lot of time manually downloading the packages, all I got was a desktop environment which will crash frequently to remind that you just wasted 1GB of bandwidth.

After upgrading, Kopete stopped working due to some conflict in ssl libraries, xchat is also not working due to some other library conflicts, dolphin the new file manager for KDE doesn’t even start and flush all kind of errors and faults when launched from command line. After the first crash the panel disappeared and I couldn’t get it back. Launching kicker returns the kde3 panel.

KDE4 is awesome when you just sit back and look at it. But when you want to work with some apps, its miserable. One of my friend had this status message on gtalk ‘ KDE4 : KDE3.5.8 :: Vista : XP ‘. KDE4 is as good as Vista when it comes to looks but its equally bad as Vista as compared to XP when it comes to work with it.

Conclusion: Don’t upgrade to KDE4 and wait till May, 2008 when KDE4 will be shipped with Fedora 9. I hope that KDE4 will not crash frequently when it’ll be embedded natively.

Here are some screen shots if you wanna have a look

BTW, you can get beta 1 for Firefox 3 here. I am not going to tell, how to install firefox

Positives:

1.Nice Default Font:

Well someone may argue that you can configure any font in any version of Firefox, so whats the good thing about this default font in Firefox 3 Beta1. Well, I’ll say that configuration is always available but nobody gives a damn to configure the font in browser. I am liking this default font in FF3 Beta1 and everything now seems interesting to read. I have Read more than 40 wiki pages since last two days.

2.New FTP Listing Style:

The FTP listings in Firefox 3 Beta 1 has got new stylesheet. Its not dirty any more. It feels good while browsing ftp now. See the screen-shot below.

3.Website Identity:

This is new feature, but I couldn’t find it useful. When you click on favicon in the location bar, a pop-up kinda thing comes up, which tells about the identity of the site you are visiting. Check out the snapshot below.

4.Drag n Drop:

You can now hold any thing in Firefox 3 Beta 1 and drag it anywhere you want. Though I could not drop the images to gimp or anywhere else, it looks good. I think its in the development stage right now.

5.Bookmarks:

Bookmarking a website or editing your bookmarks is far easier now. You can edit a bookmarked site while its loading or can bookmark the site by just clicking a button. A new star-shaped button has been added in the location bar before the go button. If a site is not bookmarked, clicking the button will just bookmark it without asking for anything. If you again click on the button, now you can edit or delete the site you just bookmarked.

6.Adding Search Engine:

In firefox 3 beta 1, you can add the site you are browsing in you search engine list just like google, imdb, wikipedia, yahoo or whatever. But this is not valid for every website. Every website in this world can’t be a search engine Checkout the snapshot or KDE.

7.Link sorting/searching in location bar:

Firefox 3 beta 1 implements a new searching/sorting mechanism for links in location bar. As you type some letters, those are now searched in the link as well as the title of the page and then the links are sorted and displayed as list. In drop down list, you can also see the sites on your bookmarks.

8.Places Folder:

A new bookmark folder named ‘Places’ has been added. It has 6 sub-folders which contains links to different site based on a particular criterion. Some of them are ‘Recently Starred Pages’, ‘Recently Visited Starred Pages’, ‘Most Visited Starred Pages’ etc. I was looking for something like this since a long time. Because every time I login into my PC and fire up my firefox, first of all, I visit 8-10 sites (students mail, slashdot, iiit blogroll, yahoo mail, gmail, forum, orkut etc.). Now, I can open all of them in just one click. I click on ‘Most Visited Starred Pages’ and done.

9.Low Memory:

Well, a review of Firefox 3 Beta 1 on zdnet, say that Firefox 3 beta 1 is consuming low memory than Firefox 2 and IE 7. That review is for Firefox in windows. But in Fedora 7, I didn’t experience any reduction in memory usage.

10.Faster:

I don’t know how to justify this, but Firefox 3 Beta 1 seems to load pages faster. What I could think was that, when you click go, it loads the page in the background for some-time and then suddenly flushes the page to the screen and it appears that the entire page has been loaded in one go. I may be wrong though.

11.Improved GUI:

The rendering of buttons, input fields, images in the pages have improved a lot and buttons and drop down menus look better now.

Negatives:

1.Extensions:

Life is a bit or I should say a byte difficult with Firefox extensions. Now, I am too much used to use these extensions that I can’t live without them. I’ll crash if I don’t have ‘Undo Closed Tab’ extension. I keep making stupid mistakes. All the extensions are not yet available for Firefox 3, so its a problem.

2.Multiple Tabs:

Firefox 3 Beta 1 immediately dies if I open more than 20 tabs. I opened my wiki saved session (39 tabs) and after sometime I was searching for Firefox. Where the hell firefox window has gone?

3.Crashes:

I don’t know what exactly is the problem, but I think Firefox 3 revolts against Yahoo Mail and GMail. Whenever I open Yahoo Mail or GMail, Firefox 3 Beta 1 crashes. Either there is some problem with the heavily loaded mail pages or it doesn’t want me to use GMail or Yahoo.

Well, there may be lot more positives and negatives. These are the things I noticed about Firefox 3 Beta 1 in last two days. As the positives list is ruling the negatives, I am using Firefox 3 Beta 1 full time these days.

PS : @Paresh I think FF3 is better than FF2 in many ways. But you may want to wait for all the extensions to be compatible with FF3.

First of all, I would like to say that The artwork team at Fedora has done a very fantastic job. The graphics right from installation up to the desktop are just awesome. Especially the default background is very nice. Here is shot of the default Gnome Fedora 8 Desktop.

Right after the installation, I fetched the nVidia proprietary drivers from here and installed them. And those were installed successfully without giving any errors or problems. [ If you want a complete howto on installing nvidia drivers. Its here.] A reboot after the installation and compiz worked out of the box. Here is shot.

Ok, graphics done. What now ? I just realized that there is no mp3 support. No worries. Codeina aka Codec Buddy is there. Just issue ‘codeina’ command from command line and a window like this will appear.

Check Fluendo MP3 Audio Decoder and click get selected, accept the license conditions and you’ll see that codeina is fetching the codecs. [If codeina does not fetch codecs or give error like timeout or some other network error. Try checking your proxy setting in System -> Preferences -> Internet And Network -> Network Proxy . It may help. ]

Ok. Now, codeina has done the job. Lets play some mp3. Note that amarok still can’t play mp3 files because it uses xine engine. So, you can choose either Totem or Rhythmbox to play your mp3 files. Here is a shot of Rhythmbox. So, Codeina also works out of the box.

Another major improvement in Fedora 8 in audio section is introduction or pulseaudio. Issue command ‘pulseaudio’ from command line and you will see a window like this.

You can control the sound stream from different players or whatever. You can mute individual streams and can even set the default devices for certain streams through this fantastic gui.

Another good thing in Fedora 8 is Eclipse. Eclipse 3.3 is back in Fedora 8. They excluded it from Fedora 7. I am happy to see it back here in Fedora 8.

Another utility that I found helpful is Remote Desktop utility. Launch System -> Preferences -> Internet And Network -> Remote Desktop and you’ll see a window like this.

Set your preferences and now you can browse your desktop from anywhere using ‘vncviewer <yourIP>:0’. Though one call always configure vncserver to get that done. But for newbies it’ll be a great help.

Also, My wireless lan card, Ralink rt2500 WNC-0301 is detected successfully in Fedora 8. But I am not sure whether it works or not, because there is not wifi environment in my lab and I can’t check it without that. [ Anyway if your wifi card doesn’t work, here is a howto on installing Ralink rt2500 WNC-0301 using drivers from serailmonkey. ]

Another improvement is that cursor was never invisible. Up to Fedora 7, I suffered cursor invisible problem on first login. [ If you are facing the same problem, add line

Options "HWCursor" off

to “screens” section in your /etc/X11/xorg.conf file and issue ‘gdm-restart’ command. It’ll be fine afterwards. ]

The boot time has also improved significantly. My Fedora 8 boots in just 45 seconds.

These Fedora 8 Screenshots and other related to Fedora 8 can be reached here.
