These are not clever hacks by any stretch of the imagination. I have not had the privilege to look at the code written by any of these companies, but I have never across such things in any project worth its name. K&R is quite categorical about discouraging such usages. > Besides such examples help _normal_ students understand how exactly > these operators work. No they do not. The way these operators work is compiler dependent. eg., it is often said ++i is more efficient than i++ when one simply has to increment i. But there is no guarantee that it will be so in every compiler under the sun. Therefore they are simply misleading the 'normal' students. >> I started with Gottfried's book, and when I finally came to Let Us C, >> I found it sick. > No need for name calling.

Fedora Core 6, Core 2 Duo with DG965RYCK motherboard
by Dinesh Joshi 21 Jan '07

21 Jan '07

Hi, Today I installed Fedora Core 6 ( Respin ) on my Core 2 Duo system. The system's specs are: - Core 2 Duo E6400 Processor - DG965RYCK mobo - 512MB DDR2 @ 533MHz ( It should've been 1024MB but the other sticks not working ) - 80GB Seagate HDD No add on cards at all. Initial impressions: The system boots up really fast. The board is quite new so requires a bit of tweaking and playing around. The default FC6 kernel doesnt support the onboard PATA controller ( JMicron ). The problem: Since the kernel doesn't have the driver built in for the JMicron chip, the kernel boots from the CD but it doesn't find the installation media and asks for a driver disk or alternative installation methods. Solution: There are two solutions to this problem: - You can use a SATA or USB CD/DVD drive instead of a PATA - You can pass the following kernel parameters to get it going: pci=nommconfig irqpoll all-generic-ide For the first option to work correctly you should be installing on a SATA HDD. You also need to change some BIOS settings: Advanced -> Drive Settings -> SATA -> AHCI ( by default its IDE ) This should get the installer started normally. Install process: FC6 has a very intuitive installer. I selected several packages according to my needs: - GNOME - KDE - Development tools / libraries etc.. etc.. The complete install size was around 3.1GB. The system took about 15 mins flat to install everything and it was up. But one word of caution, Fedora Core's installer, Anaconda, will add only pci=nommconfig kernel option in grub.conf. You need to manually edit it and add all three options ( see above ) to get your system booting properly. After thoughts: You can try playing around with the options to suit your need. My installation was done on a PATA drive. If you have a SATA drive then it will be much easier since the kernel already has the driver for the SATA controller hence it wont complain plus it will boot up without the all-generic-ide option. If your install is on a SATA drive and you dont see your PATA CD/DVD/RW/ROM them you need to pass the all-generic-ide option. The drives will show up properly. One more problem that was evident after the install was random lockups with the default kernel. FC6 ( respin ) shipped with the 2.6.18 kernel. I simply upgraded it to the latest, 2.6.19 i believe, and the random lock ups went away. Even in this kernel I had to pass all three options for the system to work normally. For some, removing the irqpoll option may work. For me it didnt work. Xorg would come up but for some reason it kept on restarting. I had to reboot the system and manually add the irqpoll option after which the system was stable. I used the respin with the hopes that the updated installer kernel would not need any tweaking to get it started the steps remain the same for the official Fedora Core 6 release. The user experience on this is amazing. I used GNOME ( yes, I was a BIG KDE fan a while ago but now I am not ) with Compiz enabled ( System -> Preferences -> Desktop Effects -> Enable ). It rocks! I then installed beryl ( yum install beryl-gnome ) and its even slicker than compiz. For intel users its no problem but those with NVidia or ATI will need to get their proprietary drivers installed and configured first. It worked out of the box for me. Some stats: - GNOME with Beryl enabled with the system working as a http, ftp, mysql, etc.. etc.. server it consumed about 250MBs of RAM. - Install takes around 15 minutes to complete ( All 5 CDs required ) - Boot up hardly takes 15 seconds - System shows a bogomips of approximately 8400 ( both processors combined ) Hope this helps someone out there who is struggling to get Fedora Core installed on his/her Core 2 Duo system :P -- Regards, Dinesh A.

Well,this discussion has been useful to me since I am in SEM-II Engg. and they are teaching us C++. >please read Stroustrup after learning a bit. I would like to ask Pradeepto what does he mean by a bit.Exactly how much is a bit? Thanks for the recommendation of books.If the library doesn't have them,as our's usually doesn't,where can we get the books?Are there online subs available?

Data recovery on a crashed drive with Linux FS
by Dinesh Joshi 21 Jan '07

21 Jan '07

Hi peeps, My Samsung SP1213C ( 120GB ) SATA disk has crashed. Its making horrible clicking sounds. The disk is not reading much. Though GRUB does come up and the kernel does start booting up but it finally panics after not being able to find initrd ( Yes, I use Fedora Core 2 :P ). I had some important family pictures and stuff in there. I tried booting to Windows and using the EXT2FS reader but its of no use. It cant read anything. It gives a bunch of read errors. I spoke to my vendor and he said that none of the recovery guys he knows can recover a disk with a Linux FS. Also, if I give it to some third party who opens up the drive, my drives warranty will be void. Samsung is of no help. They're pathetic :( I mean they'll just replace the drive. They wont take any responsibility for the data! But I guess thats normal, right? I'm not sure what I should do at this point. Can anybody help out?? Any suggestions??? -- Regards, Dinesh A. Joshi

Dear Members of the community, India Habitat Centre (New Delhi) will be the hot spot for every Linux enthusiast from 31st Jan to 2nd Feb. And the reason is - LinuxAsia 2007 - India's premier Linux and open source event. We would like to ensure that the Linux/OSS community is fully engaged with the event. What all is happening at LinuxAsia this year? ********************************************* The main track - 'technology.innovation(a)oss.in', which will go on for 3 days from 31st January till 2nd February 2007 at the India Habitat Centre, New Delhi. The second track - CXOSummit - is a one-day event being held at Hotel Taj Mahal, Man Singh, New Delhi on the 1st of February 2007. Besides that, there will be an IOSN summit, ODF India Chapter summit, technical workshops, sessions by LUGs, and last but not the least, the Expo. What are the entry charges? *************************** FIRST 500 FREE!!! ***Just 150 Free Pass Left*** Ok, this is best news - the first 500 (out of which, only 150 are left now) registrants can get the COMMUNITY PASS, which allows them entry to the 'technology.innovation(a)oss.in' track for FREE (subject to availability of vacant seats in the main hall and on a first-cum-first-served basis)! Though there is an element of organisers' checking your details and approving the serious cases only, but then, if you're serious about attending International-level Linux/OSS events - then REGISTER NOW at http://www.linuxasia.net. "Hurry up Just 150 Passes Left" DELEGATE PASSES FOR SERIOUS PROFESSIONALS For the serious professionals who want 'guaranteed seating' at LinuxAsia 2007, we have the DELEGATE PASS.

We expect 3-4 more global luminaries to be there--their confirmation is in progress. Any facilities for out-station delegates? ***************************************** We have tied up with 'hospitality partners' who can assist you in getting best deals for travel and stay. If you need this support, simply select that option while registering. What is LinuxAsia trying to achieve this year? ********************************************** The goals that have been laid down for LinuxAsia 07 are: Goal #1: Promote open source driven innovation so that India can showcase a minimum of 20 globally recognised OSS projects at LinuxAsia 2008. Goal #2: Accelerate the adoption of Linux and open source software by highlighting their advantages, sharing success stories, and discussing strategies on how CXOs can gain advantage from both "open source" and "proprietary" worlds. Goal #3: To provide a platform where other organisations with OSS-related agendas can hold their own sub-events and network with the entire community. So, we request you to register, participate, and let us know how we fared in achieving those goals. Best Wishes! Niraj Sahay Community Manager Team, LinuxAsia 07

> "Let Us C", nevertheless, a good > book. It is a horrible book. I strongly oppose the idea that one needs to begin with it. Just consider the fact that Yashwant Kanitkar teaches you the difference of: i++ + ++i + i++ and i++ + i++ + i++, which is simply undefined in the C standard and yet Kanitkar stresses on this, instead of telling the reader to avoid writing such code. > Ok. I don't want to shock many people here. And before I say > something, I must say, I did read LUC as my first C book (I think) and > found it good as well. The point is many people who start new with C ( > maybe without any programming exp ) find it easy to start with - > that's the reason its good - other wise its not. I started with Gottfried's book, and when I finally came to Let Us C, I found it sick. > But honestly, one needs to have a copy of K&R if you are into C. Very true. > And if you are doing C++, please read Stroustoup after you Robert Lafore's book is also nice although he does not use GCC in it.
