[Ilugc] One Day One GNU/Linux Command (YES)
Hurd -- Hird of Unix Replacing Daemons Hird -- Hurd of Interfaces Representing Depth One Day One GNU/Linux Command = yes -- Print a string until interrupted Summary : It prints the command line arguments, separated by spaces followed by a newline, forever until it is killed. 'yes' can be used to feeds a continuous string of the character to another process and create dummy process for learning the process control. Example: $ yes -- Prints `y' followed by a newline until killed. $ yes ILUGC -- Prints `ILUGC' followed by a newline until killed. $ yes `cat myfile` -- Print myfile content until killed. $ yes | fsck /dev/hda1 -- Runs fsck non-interactively. $ yes | rm -r mydir -- Same effect as rm -rf mydir. $ yes /dev/null -- Dummy process.

[Ilugc] My First Session for Engineering students
Hi All, Last sunday, i gave a seminar to 3 engg students on Web server, MySQL server, PHP, and some basics of web programming, like sending form variables procesing it in server using PHP, updating mysql and retrieving from it. The students were very encouraged at this, and in the evening they called me and said, We are very interested and they started working on a sample project for resume/profile management. And i am sure, in their final year project, they would be able to do a project on their own. I also gave them the demonstration of how to install a typical PHP application like Mediawiki, forum, wordpress blogs etc. But more than that, i gave them an idea, on how to bring those softwares in to common use in their college. I have already expressed in this ILUG group. I will again recall it below. 1. To implement Knowledge Management Portal in their college using Media wiki. I gave them an idea of how easily we can create new pages, and manage our data, and they are very much interested. 2. To implement an announcement portal using wordpress, for every department. This announcement portal would be used to publish all circulars issued by the principals and HOD. They would be discussing with their HOD and staffs and get back to me by this week. One thing i observed from this experience is that there are enough students who are very much interested to learn. The problem is that there is complete lack of guidance and support from knowledged quarters. Without these basic knowledge they felt handicapped and could not implement any of their ideas even if they are very much interested. When i sat down with them, they came with lot of ideas, and i just told them how easily we can implement those with WAMP/LAMP tools. I would like to bridge this knowledge divide, and i am thinking of how to interlink those industry professionals and academic students. My goal is to implant the basic knowledge to as much students as possible, so that they would be able to implement their ideas. And it should be a participative mode. The three students whom i taught would be further teaching another 5 students (of different college) in the coming week. I also want to make sure, that not any single college exploits the knowledge acquired by these students. For this, the solution is to diffuse this knowledge to other colleges, and enable inter college participation on this. I also suggested them to add Open Source concepts and particularly on FOSS tools in the symposium that they are going to do. Some suggestions: 1. What i have done is very basic thing, that need not require any expertise or great skills. However, to actually get a momentum, we need to establish knowledge pockets, on advanced technicalities like Building a Linux Distro from source, knowledge on compiling methods, linux programming etc. 2. We can evolve a list of basic skills needed for the students, and volunteer to teach them at some selected colleges. Once a team is formed, then those students should volunteer to teach their juniors and other college students. This will create innumerable opportunities and would unleash the creativity of young minds. Imagine, if atleast few in each college knows how to build a linux distro, we would have atleast a dozen customized distro in india. -- I am sorry if i am too impractical. But i just shared some of my vision with you all.

Re: [Ilugc] ERP software
/** I have to use an Enterprise Resource Planning software for one of my friend`s textile factory **/ I came across a software called ERP5 , that's specially designed for Apparell industry. I havent tried it out, but i feel it could be a good choice. WebERP: I think, its not that much usable in the present context. If we could tweak some PHP code there, we can make it usable. Opentaps: One of my friend's friend is working on opentaps. The UI is well, and simple. Since its based on OFBiz, (apache's another project), it may be given a try. Open Bravo: I think, it has too much of features, and the UI is not that much friendly.

[Ilugc] 2.6 SMP kernel -- dual core opteron processor -- irqbalance(?) - only one CPU busy always
hey gurus -- i have a HP server with 4*dual core AMD opteron processors running 2.6.9-42 SMP kernel -- one of my DBAs complained of poor performance while running an SQL query -- now when I check the 'mpstat -P ALL 5 ' o/p - I see that CPU 0 is completely busy (idle 0%) most of the time -- while the other CPUs are close to 99% idle -- I did a cat /proc/interrupts I see that CPU0 is indeed having high values corresponding to ethernet devices , other PCI devices , RAID controller and the timer as well --- I also checked that we are running irqbalance daemon and please note that we are running the kernel with noapic option -- not sure if that matters at all any inputs you may render are higlhly appreciated Thanks!! ___ To unsubscribe, email [EMAIL PROTECTED] with unsubscribe password address in the subject or body of the message. http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

Of course we can have trusted users, community repos etc. I love the Archlinux project for that. I am recommending bcoz, only if student understands the full compiling process they can work on individual modules effectively. They need not customize the distro.. but, they can atleast know how to compile it from source and make it running.. Personally i feel, there are lot of customizations needed for the Linux, to match microsoft.. probably high level customization.. It would also help in localising the distros Regards, SEnthil ___ To unsubscribe, email [EMAIL PROTECTED] with unsubscribe password address in the subject or body of the message. http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
