Posts Tagged ‘OS’ seems like google is planning to take over the world. This time its an OS from them and they call it the Google Chrome OS. The official blog calls it an “extension” of the Chrome browzer, they were kidding. Chrome OS is a lightweight, open-source PC-operating system that is built over the Linux kernel. And like most google products its supposed to be free of cost as well. Now thats a real deal..all the freedom of open-source and the support of a giant, thats most men’s dream.

The very concept the Chrome OS is that its the browzer thats the real OS. Most applications are kept online. Now what the OS is supposed to provide is a quick-starting light and power saving OS that can support this concept. Cynics might ask then how can it be a danger to the current  OS giant Microsoft when chrome is not designed for those power users out there at all. The issue gets strong when the figures show that most of the PC users are not the so called power users. They use PC to access the net, to stay in touch, to make words docs, spreadsheets and do presentations.People dont want to worry about carrying around files and searching out for drivers. Now for them Chrome is the answer to their prayers. And they are the majority. But of course those power users are gonna have a bad time with Chrome. Those like the multimedia eds and the gamers. But they are just a handfull in this world.

The announcement came this tuesday night and in just two days itself it has become one of the most discussed topics in the internet world. People are shooting questions on more detailed informations on the OS and its supports. Unconfirmed reports are coming from around the globe regarding Google negotiating with most OEMs invluding Dell, HP, Asus and Acer. But till this moement they havent given an official comment on that.And as far as the experts can think, it will be a good offer for those OEMs as well. Afterall it can save them around $50 per machine.Considering the ability of Chrome to run on X86 and ARM processors there is every reason to think chrome to be better suited for Netbooks than Windows.

However I was feeling like its Google’s vision into the future. They have already understood computing cannot be contained in a small box. They have realized cloud is the future. With the ability of clouds to share resources the internet becomes the backbone of all computing and all you will ever need is a browzer(what will a browzer look like at that time is something I cant predict).Now in that scenario, it will be the Chrome that makes the future. And what can we use Windows for then…perhaps to sit back and watch the clouds moving in the sky. I would like to quote a a few words I have read about this issue, “If indeed Google puts out a fast, easy to use operating system that lets netbooks soar and free users from constant software patches, Microsoft will find it very hard to explain to consumers why they should continue to use its software, other than just out of a foolish consistency.”

But at the end of the day,there is one thing that makes me wonder…what happened to the android project. HP already had plans to make it their OS for netbooks . Chrome is an entirely different OS and has nothing to do with the Android. Did they really drop the Android project or did they decide to keep it exclusive for the mobile devices. Man its Google. When they do something, there is always a purpose.

Finally the much awaited Ubuntu 9.04 has released. Although I didnt yet install and use it, I hearing a lot of noise about it, especially as a total replacement to Windows. One thing I am hearing the most is about the speed, and a faster loading time. I am really dying to compare it with the new Windows 7 RC1. But the rest of the stuff I hear are all based on some new applications that are bundled along with it. Like a new media player that can automatically download the subtitles from “open” and a package manager that can take a backup copy of all the packages and even perform an offline installation similar to apt-get.  But this package manager is still way below the windows counterpart where you install an application with just one button click.

The look and feel thing, from what I have seen, I feel the UI of windows 7 (i have been using the beta for sometime) is far better than that of Ubuntu.. W7 interface makes a lot of things easier to connecting to network directly from the tray and those cool transparency effects. With that default themes of both, I felt like i went straight to the Sahara desert after my vacation in Bahamas.

But one major problem I am gonna have with Ubuntu is the lack of drivers…especially the graphics and sound drivers…I am having an nVidia 8600 GT graphics card and a creative audigy sound card to help play my Altec lansing. Ubuntu disappoints big time. Afterall all the money I saved on replacing windows with Ubuntu is lost counting the money I spent on these hardwares which are now nothing more than just sitting ducks. Thanks my speakers are having a stereo mode for atleast I can hear some sound,though very feeble.

And the gtalk..I live in Gtalk…whatever complaints they say about the little gadget from Google, I cant live without it..Now the only way continue using gtalk is to use something like Pidgin..but the bird never really talk..there is no voice support. Heard they are gonna pack it soon, but like most other opensource things, the date is still indefinite. I really wanna talk with my friends..especially when its “free”.

As a Computer Science student,graduating in about a week, I love ubuntu as a developers platform. Most of my projects projects including my final year project was done on Ubuntu. And my final project was actually to modify the kernel itself for performance tweaking. The support forum is good and the response come pretty fast. On the contrary for an authentic windows operating system, that support comes as a part of the bundle you ‘purchased’. And forget about the possiblity of me doing my final project on changing the Windows kernel(may be thats why windows is so stable..he he). friend Anirudh is working in Microsoft, may be he can one day tell me how does a windows kernel look like.And not to forget, they have made considerable enhancements to the kernel by Windows 7, finally coming up with the worlds most compact kernel.

Now lemme come back to where we started. Is 9.04 a complete replacement for windows. Honestly in my opinion, NOT YET. Because still if my mom wants to use a pc surfing the net or if my little brother wants to use my laptop for playing some games , then there is no way I am going to recommend an Ubuntu for them.I will buy them a W7 or a Vista. Ubuntu might be the favourite for all the developer folks,that wud include me too, but considering the common people and their needs, I think Ubuntu has a got a long way to go before u can really consider it as a replacement for windows. Not all people will need to see the kernel code before he starts using it. And the number of those common people who use computers are many many times greater than the number of dev guys around. I wonder why these Ubuntu people forget this simple thing. May be this is where the MS pro’s score over the weekend programmers..

PS: I am not against open source or a die hard fan of Microsoft. I have contributed to open source as well. Please dont misunderstand me.

Finally microsoft have finished working on Windows 7 RC 1, the most anticipated piece of software this year(lets not forget Ubuntu 9.04).Hmmm,I dont think the final release which is expected to happen later this year or early next year will not be a lot different than RC1.So this one will do the trick for most people.

Anyway make sure your PC is 7Ready. So here is the system hardware requirements:

  • 1GHz 32-bit or 64-bit processor
  • 1GB of RAM
  • 16GB of disk space (or 20GB for 64-bit users)
  • DirectX 9 graphics device with WDDM 1.0 or higher driver

If you want to use Windows XP Mode (which lets you run Windows XP programs), you’ll need at least 2GB of RAM and 15GB of additional storage space as well as a CPU that supports hardware virtualization.

Alright then…go run for it…I wish it works well for you..godspeed.

1. System beeps: Sick of those system beeps.Well then tell them to shut up.Here is the command. Type in the command setterm -blength 0 in the terminal.You will no longer hear a beep in that session. If you dont want to type it all the time, then add it to the system startup as mentioned in trivia#2. Have some peace of mind.

2.Command History: As you all know command history is a handy tool when using a terminal. But sometimes you will notice that the command u are looking for is already gone from the history.Well, to avoid it, you better set the size of the history archive by putting the following in the .bashrc file:



Oh,if that looks like a too big archive to search for a command,then u can always make use of grep. The command will be like:

history | grep -i str

where str is a part of the command u are looking for. So no more forgotten commands in your life.

PS: You can unset the value of HISTSIZE and HISTFILESIZE to permenantly keep a history of all commands ever used, but its not recommended for obvious reasons.

Tech Trivia #2: Linux Startup

Posted: April 12, 2009 in OS, trivia

Startup files in Linux: You want to add a command to be executed when the linux system boots. Then here is something you should know.

systemwide defaults, mostly setting the environment (works on all Bourne-type shells)

systemwide functions and aliases for Bash.Changes made will be affecting all the users.

user-specific Bash environmental default settings, found in each user’s home directory .User specific.

user-specific Bash init file, found in each user’s home directory (the local counterpart to /etc/bashrc). Only interactive shells and user scripts read this file.

Logout :

Not just login, logout is also a point at which you would like something to happen

user-specific instruction file, found in each user’s home directory. Upon exit from a login (Bash) shell, the commands in this file execute.

PS: This does not apply to csh, tcsh, and other shells not related to or descended from the classic Bourne shell (sh).

Tech Trivia #1: Linux Command Aliases

Posted: April 12, 2009 in OS, trivia

1. Typing long commands: If you are repeatedly typing long commands, may be with a lot of parameters, then you should seriously consider using an “alias”. You can create an alias by adding alias newalias=’mycommand –option1 –option 2 –option3 –option4′ to the .bashrc (in /etc/ ).

eg:- alias l1=’ls -l -a’

Now if you type inn l1 it will execute the command.If u want to use more parameters u can use it with the alias as well.For example ‘l1 -p’ wil be treated as ‘ls -l -a -p’. View a sample bashrc.

PS: This does not apply to cshtcsh, and other shells not related to or descended from the classic Bourne shell (sh).
