Minutes for the Feb 2002 BLUG meet

Date : 23-02-2002

Although there was alacrity in the air,by the time everybody made it to the rendezvous & settled down it was 6.30.pm. Mahendra had an optimistic cheer saying that we were breaking the pervious records.I mean we were quite a bit early than the previous "latest start times".

He always has good news for the crowd there. Last time it was the goody vouchers & this time he made anouncements that this time the BIG event ( I mean the Linux Bangalore/2002 ) was being scheduled for 9th,10th & 11th of December 2002. Yeahhhhhh!

As a part of efforts, to better the quality of the talks for LB/2002, now on there will be a "Theme of the Month". There will be talks + demos by the adepts in those particular fields....cool na? Hey btw we are starting off with 'Clustering'. So on the whole i guess the meets in the comming months will be 'Not to miss' kinds. So folks hope to see more of you there!! :)

There was also a discussion on "Corporate Involvement" in the BLUG activities. The general plan was to invite corporates to BLUG meets when we had a theme for the meet.

Yeah, then the talks started off, we had 3 talks scheduled.

  1. Introduction to Symmetric Multiprocessing (from a kernel programmers perspective) - Ravikiran G Thirumalai
  2. Filesystems in Linux - Balaji
  3. Configuring Oracle 9i in RedHat Linux - Surjo Das

RaviKiran started of with clear description of multiprocessor model & then came on to various issues on kernel level dealing with Symmetric Multiprocessing. All features quite in depth, with example program codes.There were details of implementing Semaphores & spinlock.This talk lasted for a kinda long time & then we had a Q&A session, which eventually lead to a 'race condition' on the spinlock implementation & release lock....issues between Hanish & Ravikiran. oops! it was more than an hour by then, so a quick wrap up. Paved way for the next talk..to sum up, the talk was informative & good .

Balaji started his part by delving into the history & evolution of the different File systems. Then we had a quicky on the Basic Principles plus stuff on Superblocks, Inodes, Device links etc.. Virtual FS were then discussed. Hey i personally liked this liner that Balaji used to intro this subtopic -

"All problems of Software engineering can be solved by an extra level of Indirection".

VFS was on for some time. Then we had Object Orientedness...then we had Ext2 Implementation - right from physical structure & block group to optimisations using caching & preallocations. We had some interesting info on Journalising FS. Finally the talk ended with touch up on other File systems - Log structured FS & CODA. On the whole it was a good talk.Time constraint kept the speaker's descriptions brief.

The talk by Surjo Das was Configuring Oracle 9i in RedHat Linux . It was a neat & detailed talked with good amounts of usefull do's & dont's. He guided us with tackling the 'binutils' problem. Basically we learnt that Downgrading helps. Kick off that problem. Followed by HOWTOs on starting & shutting down. Then he talked a bit on Circumventing installation on AMD. Surjo Das also suggests dbspecialist.com for help.

hey folks thats about it.. the talks finished..& it was time for snacks..we all hung around there for sometime.. & then packed up for the day.

One thing i cant just forget to say is that without Atul & Biju,the place lacked some kinda charm.

The BLUG would like to thank Federal Technologies for letting us use their office for our meetings.

until next time signin off folks...
