20 Years of computer Virus
It was in November 1983 that U.S. computing student Fred Cohen created the very first computer virus as a research project during his studies. The creation of the virus gave rise to such consternation that other similar tests were banned.
Cohen defined virus as "a program that can 'infect' other programs by modifying them to include a ... version of itself".
The first of viruses written for the IBM personal computer is widely acknowledged to be the "Brain" virus.
The other importane viruses that followed are Tequila - the multipartite virus, Concept - the Word macro virus, Melissa - the e-mail-aware virus, The Love Bug - the social engineering virus and Nimda - denial of service virus.
SQL Slammer and MSBlast are the latest and most deadliest of the viruses.
This article gives more details about birth & growth of viruses.

VPN on Linux
This software company with its development centre in Bangalore needed to needed to establish VPN connectivity with its head office in the US. Various possibilities were experimented with, but reliability was a question mark. The client even upgraded their Internet leased link to a premium, low latency service, incurring a cost of Rs. 10 lakhs/year. With no concrete progress in sight, Yukthi Systems was called in.
Using the Linux platform, Yukthi set up the VPN network, including the remote end. The solution included advising the client on the appropriate ISP, which saved them Rs. 5 lakhs/year. The client could save a further Rs. 2 lakhs on VPN software/hardware. Encouraged by its clear success, the client sought another Linux-based VPN connection to its customer with a NetScreen device at the other end.

Dear [[-FullName-]],
Return-on-Investment. Probably the most bandied about buzzword since the early 90s. ROI as a concept is given to wide range of applications and interpretations, and most companies have their metrics in place. There's one area that needs as much importance - RoEI (Return on Existing Investment).
It's an important discipline to ensure that existing systems continue to deliver value, what with the ever-tightening budgets. Rightly so, RoEI is the theme for this issue of Yukthi Infoswitch. Read on.
Regards - Ramakant Jawalkar

Assessing the RoI
Measurement of technology ROI in an organization depends on the type of investment one has made and should be looked at on a case-to-case basis. There are some complex financial models that allow you to calculate the ROI. However successful organizations view IT as an asset and do not search for value in IT. Full article from Network Magazine by V K Ramani, Head IT, UTI Bank.
Case Study: RoEI as the Prime Concern
Many firms tend to overlook IT solutions which do not translate into immediate returns. This is especially true with companies, where the IT budget is a minor component of the total expenditure, and where IT is used as an efficiency enhancer, rather than a key component. A South African company dealing with paper products wants to have an electronic messaging system incorporated, without going for system upgrades requiring heavy investment.

Reuse: What to Watch Out
Two of the biggest challenges of the IT world are improving time to market and reducing costs. Users want to see improvements immediately, and management demands an ever-increasing ROI.

However, there is one possible solution to these problems: Reuse. Full article from Earthweb, by James Bean.
Redeploy and Reap in the Benefits
Accelerating technological innovation has compounded the problem by creating a proliferation of surplus and idle assets with the associated challenges of obsolescence, waste and under-utilization. The professional members of the Investment Recovery Association conservatively estimate that about 10% of the assets on a company's balance sheet are either surplus or idle. Redeploying such assets to the optimum advantage of the organization is sure to bring in rich rewards.

Why Linux Is Wealthier Than Microsoft
It is true that Bill Gates has more money than Linus Torvalds, but, when it comes to creativity, knowledge and software development talent we cannot say the same. Gates depends on his employees who are motivated by money, while Linus's team consistes of geeks who are motivated by pride and challenge of working towards a common goal of universal, low-cost and bug-free software.Full article from BusinessWeek by Russ Roberts.
