Unix turns 40

June 6, 2009

Forty years ago this summer, a programmer sat down and knocked out in one month what would become one of the most important pieces of software ever created.

Computerworld.com has a nice article about the history and some prediction on the future of Unix.

How to make your software project fail

August 29, 2008

Why do 66% of all IT projects fail, 20% go over time and budget ? With over 20 years of IT experience, Sander Hoogendoorn talks about project anti-patterns stereotyping them as Titanic projects, Golf course projects and many more.

You can see this talk on Parleys.com. Its about one hour and teach you how to fail a project. You may know some of the anti patterns. But it’s always good to be reminded about it.

The race to idle

May 13, 2008

Modern CPUs are great. They have all sorts of advanced power saving features, which is one of those nice cases where everyone can save money, gain performance and claim environmental credentials at the same time. Everyone’s a winner.

Well. Everyone’s a winner as long as your software doesn’t suck.

Matthew Garret talks about the current state of power saving abilities of modern CPU’s and how software is trying everything to make things worse.

Some people write software that lets you choose different power profiles depending on whether you’re on AC or battery. Typically, one of the choices lets you reduce the speed of your processor when you’re on battery. This is bad. It is wrong.
The people who implement these programs are dangerous. Do not listen to them. Do not endorse their product and/or newsletter. Do not allow your eldest child to engage in conjugal acts with them.
[…]
Failure to do so will result in me setting you on fire[4].

The making of Wine

April 16, 2008

“We are completely rewriting the Windows operating system from the ground up,” he says. “Basically we took Microsoft’s crown jewel, that they’ve had billions of dollars to develop using tens of thousands of developers, and we, the open source community, have essentially re-implemented that. We are the scrappy underdogs. Here’s where the Hollywood music comes up.”

This is what White (the CEO of CodeWeavers) is telling about Wine.

Wine is a software application which aims to allow Unix-like computer operating systems on the x86 architecture to execute programs that were originally written for Microsoft Windows. Wine also provides a software library known as Winelib which developers can compile Windows applications against in order to port them to Unix-like systems.[1] (wikipedia)

The interviews goes on

So, in 2008, the 1.0 version will hit the streets and the timing could not be more perfect. White admits that not every Windows application will work flawlessly on Wine, but many a critical one for the enterprise has been specifically optimized. These include Microsoft Office, Lotus Notes, Microsoft Project and Visio, graphics applications like Macromedia Dreamweaver MX, Flash MX, and Adobe Photoshop. Several Linux distros ship with Wine, too, White says.

As I’m using Wine now and then for windows programs (for example to test webpages with Internet Explorer on linux) I know how helpful wine can be.
Give it a try!

I am ashamed to use proprietary software

March 3, 2008

BANGALORE: Krishnakant Mane says that the freedom and flexibility provided by open source software enables him to work with a variety of interfaces and is integral to his work at the Tata Institute of Fundamental Research.

The news site www.hindu.com has an interview with a young man who is visually disabled.

“Why should I let the software limit what my magnifier or reader can process?” It is this lack of flexibility that he opposes. Not being employed, a visually impaired person cannot afford to pay huge sums of money, every time something needs to be modified, he argues, speaking to The Hindu on the sidelines of the ongoing Open Source India Week programme.

The interview show good that being gratis is not the most important property of free software/open source.
The freedom to modify and to distribute this modified version is the main benefit which distinguishes free software/open source from proprietary ones.
