Summer Internship :First week

hi all,
Right now I am at nagda(M.P.) for my internship at GRASIM chemicals.It's been a week and I am enjoying it completely.We are a group of 10 students in chemical division.Normally we go to the plant and visit different manufacturing sites.Due to strict discipline, we wear a helmet which we try to put on and off enormous times.Since I came here,1st thing I was looking for was internet connection but didn't find much options at such a place.After so much analysis, we thought to use GPRS connection.I recharged my airtel sim for unlimited plan.But now I have realized that it is in roaming, so it's slower than i had expected.

Finally we have 2 connections and 6 students in our group.So, we are always experimenting with creating shared connections.Sometimes we use LAN wire to connect.Sometimes,we create wireless ad-hoc and sometimes create proxy server(using privoxy).Till now we are having fun.Yesterday we went to ujjain to visit famous "Mahakaleshwar" temple.There we had a funny incident.When we bought the tickets for returning,the train started taking off.We entered into different class due to rush and ended up paying fine for that.Actually it wasn't fine,it was bribe.We were in no position to negotiate ,so we paid the money.We didn't get the receipt but paid less money and became the integral part of corruption.Although we had done no mistake considering the situation.
anyway that was a lesson for all of us.Now we have 50 days more to live at this place.Hope to spend it nicely.

Download speed through apt-cacher and dependency problem with downloading so many packages at a time

I am not able to stop experimenting with ubuntu lucid lynx the time I installed it.With the apt-cacher,it's easy to download all the packages that you like.So,I was there with synaptic package manager and kept on selecting large number of packages.Finally I got a collection of 148 packages with 220 MB size.When I started to download,I saw variation of speed which is very common but I would like to point it out by some snap-shots.
1st picture shows the usual speed of download through apt-cacher which is 347 KB/s.2nd one shows unusual high speed 2843 KB/s.

But sometime we suffer low speed also.Just like this.

Now,apart from speed,there is one more thing that I would like to share.Since I selected a lot of packages and started downloading all,I got some installation problem.All the packages were downloaded but couldn't be installed properly.Very less packages were installed because of dependency problem.No idea how did it happen.Probably,when there is a huge number of packages ,some of them might have dependency due to others files in the download list.So,in my view,large number of packages should not be installed at a time.

By the way, I sent these dependencies report to developers officially.Here is one screen-shot which explains it.

Conclusion :- try installing less number of packages at a time.

performance review of ubuntu 10.04 lucid lynx

hello friends,
Ubuntu launched its Final release of lucid lynx 10.04 just 2 days before and I couldn't stop trying it as soon as I could.Reason is not that I was waiting eagerly for its final release.Real reason is that I had done some mistake in hard disk partition while installing slackware which caused me loss of linuxmint which I was using for a very long time.So, finally I thought to try fresh and final release of 10.04.
oh boy,What an OS.Surprisingly it can be called as the perfect OS.Lookwise,it has got better.Also,the most exciting feature is its boot time.Amazing boot time must have impressed everyone.Shutdown time is also faster.This has got attention of some people who are claiming that skipping disk check can also reduce boot time.Anyway,I don't want to create any controversy here.
Talking about look,It gives a sight of mac.The minimize, maximize and close buttons of window is on the left side which gives you feeling of working on mac.Anyway that feature was available previously also but not as default(a package "mac4lin" changes the look in that manner).New Gwibber social client is also very exciting.Gwibber can be configured to broadcast status on facebook,twitter etc. and to see other's status.
Recently "ubuntu tweak" became my latest crush as It has got nice and sexy packages which synaptic package manager didn't let me try directly.visit for more info about tweak.As I am in a university which does not provide with a superfast internet connection but allows downloading packages with apt-cacher,I couldn't stop downloading all the packages which caught my attention.Well,It's definitely wastage of resource.
In final words,ubuntu 10.04 is just lovable and awesome and great experience so far.Don't know how soon the bugs will come out.Till then,enjoy lucid lynx.Happy open source.
