ubuntu 9.10 karmic koala performance on Deepak's Laptop

hello friends,
today i saw the performance of ubuntu 9.10(karmic koala).I didn't install it but my friend did in front of me.He had ubuntu 9.04 installed, so he tried to upgrade to 9.10 instead of installing.So, he made bootable USB of alternate disk.But, sadly we couldn't upgrade it.instead,we had installed 9.10 into separate partition. now he had 3 OS.
Finally we started testing it.First we tried to use pidgin client which wasn't there and we saw empathy.Empathy has become default IM client now in ubuntu.Still we downloaded pidgin and run.well, empathy is good change, i must say.Next we tried DC client and it was okay okay.And then accidently we removed open office for which he was blaming me. But I was only trying to install vlc.
Most of the things are same and it is showing different performance on different laptops.on acer laptop,my one friend could not use it and on dell studio it has graphics problem.Browsing is as fast as more new thing that i saw was,it asked for internet connection settings before installation which was optional. Rest,everything was good but not much impressive.I still think linuxmint is better option.May be, i should wait for sometime to be more sure.

linux mint experience

hello friends,

i recently tried windows7 RC version and ubuntu 9.04 jaunty.previously i had windows vista and ubuntu 8.10.So i thought to upgrade ubuntu as i liked it so much.on the other hand,vista compelled me to replace i switched to windows7.definitely it was faster than vista but certainly not stable enough to impress.well, i am not professional in this field to judge accurately but i am interested in trying different and new and efficient products.
It is just a week ago that ubuntu has released its 9.10 karmic alpha version.So, my friends have downloaded it and some have started using this while i am still waiting for its stable version.Last night when i thought to try a new distro of linux, I tried to surf our college website bitsfoss which is a repository of open source stuffs.I downloaded linux mint 7 gloria.I put this in USB and made it bootable through ubuntu's cool application "start up disk".

Finally I used mint as live cd and it was awesome.I just loved it.the display is undoubtedly better than ubuntu.since i have just tried it,i can't say more. But if anybody is really interested,one can visit here.

Now that ubuntu has released its alpha3 of karmic koala, I am excited to compare with it.But first I should wait for its final release.

if anybody reads it, i would ask them to vote for either mint7 or ubuntu9.10 in comment.

social service with nirmaan

hello everybody,
today is an unforgettable day for I joined "NIRMAAN CLUB".it is a club that serves for non-profit helps the society to improve with the little individual efforts of our club.I am in 2nd year right now.Last year I missed to join it.But this time the recruitment process was different.We had to go through GD(group discussion) and PI (personal interview). well,this is not as organized and difficult as in IIM(Indian institute of management) but definitely it is a good recruitment process.

well,I got a message in the morning that I am a part of it and I can join the meeting today.I went there and we were told to assemble in afternoon to visit a village near our campus.It was about a survey in which we had to go houses of village in groups of 3 people. we had to know about the basic problems of village and their source of income.It was my first time and I was quite excited.

finally we reached there and as soon as we started asking villagers we saw the their problems.I had seen almost same problems in my village also.But listening their problems was a different experience. I saw that many parents wanted to send their children school but they could not afford the fee. Also there was not any government school above 5th grade.I really felt that we should do something for it.At least I am ready.But I have not figured out what and how I should do it.

today is 15th august.its our independence day.but I saw that children were not independent.But this is my first day in "nirmaan". I have time to think.well, nirmaan is not just this. for more about it visit nirmaan official site.

symbolic link(linux) Virus Incident

hello friends,
today I would like to discuss a very simple topic related to linux and how it bothered me.recently I was working with linux trying to learn "symbolic links".Symbolic link is a special file which points to another file in the is similar to shortcut in windows.

if you give the command ls -l in your terminal then you can view link files.if output starts with l then it's symbolic,to create a symbolic link we have to use "ln" command with -s option."ln" is for link and "-s" is for symbolic option.syntex is like this ln -s source destination.

now, source means the path of file or directory where it originally is. and destination means the path where you want the link to have to specify the name of link and this should not exist in system otherwise it will give error.

But I did something which I forgot later.I made a symbolic link by typing this ln -s /home/gaurav /home/gaurav/h. since every file of linux was in "gaurav" folder ,when i went in "h" folder inside "gaurav",i found all the files again in this folder including "h".when i again double-clicked "h" it took me to same folder which contained all files including "h".I didn't remember about symbolic links and instantly I was worried that there is some virus in my system.I had heard earlier that there is a virus which creates a folder in each folder including itself.

after some days when I opened shell and typed ls -l, I found "h" showing l which means it's a link only.then i was relieved and deleted this. then I typed ln -s /home/gaurav/videos/jal.mp4 /home/gaurav/Desktop/jal. by this I am able to view this video directly through desktop. I need not go anywhere.and this is done without copying the video or without "cut and paste" from its original destination.

this was a new thing for, I thought it would be good to share this.May be someone new like me would get help from this.But , if you are master of shell, you may laugh at me.

thanks everybody to read this post.

CLI over GUI

hello folks,
I am learning a bit linux, I thought it would be better to write something related to that.Don't worry , i will not teach you commands here(there are so many sources for that). I was thinking that CLI(command line interface) seems to be boring and cumbersome to use and I know so many people would say the same.Most of us are used to of windows' GUI(graphical user interface).Around 5 months ago my friend bought a laptop and got windows vista as default OS by that company.When i asked him to use linux,he said that as he had been using windows since childhood,he was more comfortable with that.Now i think that how can you compare two things without knowing both. If you also admire GUI then this is for you.CLI has really got some advantages over GUI.lets get it one by one
  • with a GUI, only the options provided by the interface are available to the user

  • lack of space on a screen can limit the number of options that a GUI displays

  • no standard methods exist within GUIs for performing standard command-line tasks, such as linking commands in sequences, redirecting output from one destination to another, or collecting commands into scripts

Shell keeps history of recent commands.its very useful.and, if you have to perform certain operations in sequence then you can create shell scripts script is just like batch files in windows.

there is one more thing that i have recently come to is more useful in hardware terms.Shells are much less resources-intensive than GUI' requires less memory.It means that command issued in shell will run more quickly than in GUI.

Only thing that i feel difficult is to remember commands.well,once you get used to it,its much easier than you think.
That's it for today.hope,you got something useful.

restoring grub menu

hi people,
finally pushed myself to write one about a technical issue. recently ,I reinstalled windows vista successfully but after restart i didn't see any grub menu to boot linux(ubuntu).At that instant, i was shocked as i thought linux was gone.Since vista had overwtitten the mbr so it used to boot vista directly.I tried to restore grub menu through a live cd of linux which is done through typing some commands in terminal.Basically, anybody can copy those commands from . But those commands were useless for my system as the "stage1" file was washed away from grub folder.finally,i downloaded an iso image of "super grub disk" and made a cd. then i booted through that cd and everything started working fine.when i saw grub menu again, i was so happy.
