Reaching out to 350 colleges in Andhra Pradesh

With single track pursuit of promoting and developing Open Source software, TWINCLING Society today reaches out to more than 350 colleges in Andhra Pradesh.

Member volunteers have furthered the vision of OpenSource by walking the talk and visited colleges all over Andhra Pradesh and also parts of Maharashtra. The response has been amazing and we have been humbled by the affection and support of the students at various colleges.

From sophisticated air-conditioned seminar halls at 22 degree celsius to thatched roof class room in sweltering 46 degree celsius we have done it all ! Our brochures, cards, flyers, Open Source media CD dispatch continue to support the face 2 face interaction that we have with students and individuals.

Please visit the Photo Gallery to see the background work that goes in to make sure that your college receives continues updates from TWINCLING Society, Hyderabad AP.

Virtual Reality, OpenGL and SDL based 3D programming - Sat, 8th Sep at 5pm

An eminent speaker, Mr. A. P. Rajshekhar, will be delivering this interesting and informative talk on Virtual Reality, OpenGL and SDL based 3D programming.

Virtual Reality is a technology which allows a user to interact in a computer simulated environment, be it real or imagined one.

To realize the rich graphics environment for the user, it is necessary to have toolkits and libraries.

Simple DirectMedia Layer (SDL) is a cross-platform multimedia, OpenSource library written in C that creates an abstraction over various platforms' graphics, sound and input APIs, allowing a developer to write a computer game or multimedia application.

Open Graphics Library (OpenGL) is a standard specification defining a cross-language cross-platform API for writing applications that produce 2D and 3D computer graphics.

Mr. A.P.Rajshekhar is currently a Project Engineer (Tech Lead for Web development team) with C-DAC, Hyderabad.

Mr. Rajshekhar holds Bachelors Degree in Computer Science(Honors) and Post Graduate Diploma in Advanced Computing(PGDC) from C-DAC.

While pursuing Bachelors Degree, he worked as a Developer with Arushi, a NGO in Bhopal for 2 years. Here he was involved in development of PC based Synthesizer using Windows API. Presently, he is working in multi-lingual interface enabled Learning Management System based on J2EE. His other endeavors at C-DAC include low-cost SCM solution for SME and development of Quality Assurance Framework for e-learning Systems.

He is a regular contributor to DevShed portals on topics ranging from Game programming to web based application development. His areas of interest are 3D programming and Virtual Reality systems.

Mr. A. P. Rajshekhar will talk in detail about the following:
. Virtual Reality
. 3D Programming concepts
. Simple DirectMedia Layer (SDL)
. Open Graphics Library (OpenGL)
. Programming Illustrations & Scenarios

Date: Sat, 8th September, 2007.

Backup & Recovery TSM update

Ms. Namita Iyer, delivered an awesome talk on 'Backup & Recovery' - an Open Source perspective to a highly participative and thrilled audience.

Namita Iyer discussed about the basic need of a backup. She talked about full backups, differential and incremental backups, backup of backup - auxillary copies - inline aux copies, online backup (backup as users are accessing) - quiescing and snapshots, backup of different applications - mail, database, backup complete disks - block level backup, backup to different media - tape, optical, reusing backup media - pruning unwanted backups, restores: search backed up data - indexes - and selectively restore, different backup configurations - backup to NAS, SAN, Lan-free, Server-free (proxy).

Namita also discussed about Recovery points, RPOs and RTOs - Replication and continuous replication (app aware) with recovery points, add-on features of backup - compression, encryption

A very important highlight of the discussion was, Archival - how is it different from backup ?.ILM solutions for file and mail.

Next up in discussion was features offered and issues with Commercial backup vendors - CV, Veritas, CA brightstor, EMC Networker (legato).

Namita Iyer talked at length about OpenSource backup product Amanda - Advanced Maryland Automatic Network Disk Archiver.

Manoj, Chaitanya, Vimal and Mahen came up with real life observations in the context of recovery. Vimal delivered an impromptu explanation of the MD5 vulnerability and how it came to light.

Thanks to everybody who made the TSM such a memorable event.
