This is the sort of thing I have avoided writing about and thought I would not be, for a long time to come – I was afraid to too, mostly because I felt I would be able to or would get too involved in warding of the slack I would get for saying this. But reading this article that Sriram had linked to in his blog brought a mountain of stuff tumbling down. (I don’t know why I am so much into this software-ethical-stereotype thing these days, I have work to do you know). Before you go ahead and read the article linked above, here is what I have to say. This is not a long story, but one of those minor incidents that have stuck on to gnaw at my phsyche.

Rewind several years back to when I was in my second year of undergraduate studies. I had just got my first computer (yes) and Pooja had got hers. We didn’t really have internet connections those times, though we did have the modem and required hardware. We eventually figured that if we needed to talk to each other, we could use one of those direct modem-to-modem dialup software. After a lot of tinkering with dialup software and modem settings, we had something going that mostly worked for us. I had a copy of some old dos based software – I cant seem to recall its name – that we used to dialup each others computers and basically ‘chat’.

The software was the most reasonable one I could find for our purpose, but was however seriously limiting and got rather frustrating after a few weeks of use. God-geek-in-the-making that I believed myself to be those days, I figured that the only way I would get things to happen my way is by writing a modem communication software of my own. (I know what most of you might be thinking, but those days it wasn’t too surprising to see how often this particular approach was the panacea to all my ills).

Those days I also got a chance to talk to one of the few men who seemed to know everything, or atleast had a damn good idea about how to get to know the few things that he might have missed. I got a chance to talk to Jayakrishnan K about the modem’s idea that I had on my mind. JK would know about these things – he should because he had written Kerala’s first BBS (bulletin board service) by hand (as a couple of COM files on a DOS machine doing all the multitasking and all). A short discussion later, I had my head full of X-Modem, Y-modem, Z-modem etc and I was reasonably charged up. The error control would be hard, he had warned me, but that was ok.

So I got home and start off, eventually I figured that I probably wasn’t as smart as I thought I was. I was using intervue (Ralf Brown’s fabled Interrupt List (Ralf Brown is now Professor at CMU)) for reference. Somehow some things didn’t seem to make too much sense and I needed more information on how to initialize the modem correctly.

This is where GPL stepped in. I turned that in the pile of commonly shared source and software in the college students circles I had a piece of software that did modems communication. I wasn’t really sure what the full intent of the software was, but It has what I wanted – it had assembly code to initialize a modem and set all the settings and such. And being assembly code that manages a hardware device there weren’t too many ways about – you had to load some registers, write to some ports, call some interrupts etc in a certain fixed sequence of ways. Well if you are creative, you can think of several ways of accomplishing the equivalent of

Mov AX, 10

But that by itself didn’t mean that the code to initialize the modem would be written very differently by me, once I had seen how it is to be done. It also turned out that the software (as you would be expecting by now) was GPLed.

After the excitement of reading the ASM snippet I had a look at ‘COPYING’, the GPL text file. It seemed to me that if I were to use this piece of code from here to write my modems software to talk to Pooja the entirety of the code that I write would have to fall under the GPL license. It would not be my code anymore. Which is to say, that I would not be free to decide what I do with it – weather I sell it or hide it or share it – that choice would not be mine anymore. That was really disturbing for a while, because here I was wanting to write that piece of modems communications software to talk to a friend and I had a solution in hand, but there was nothing I could do about it – without subjecting myself to legal risk, had I written the software and shared it around without giving away my code. That was my first introduction to the viral nature of the GPL, though at that time the only word I could think of was ‘unfair’.

Then I figured that I probably needn’t tell anyone and I could write my software anyway. But then I wondered what would happen (with the notion of fame) that I had this famous piece of software and then one day someone realizes that I actually did have this piece of software on my hard-disk and then they would say that I stole this code illegally. This bothered me a lot because I like to think of myself as an ethical person and tend to get reasonably bothered by the converse. Immature as it may seem, I also wondered if no one could ever write modem’s communication software again.

And in time the feeling came to pass, and my code never got written and we used the same old piece of software until we bought ourselves internet connections and things blew over. I still wanted to know if there was a way out.

Years later when I had my first chance to meet Richard Stallman, founder of the Free Software Foundation and the GNU project and author of the GNU GPL, I wanted to know if there was a way for me. But in the passing time many other things were beginning to affect my thinking and I was beginning to be more bothered about the small programming communities and their spirit of unbounded sharing and coexistence with the commercial world that the rising tide of GPL acceptance seemed to be wiping out. I feared for those communities and I felt I was part of them.

When Stallman finally did come, he was visiting model Engineering College to talk about the danger of software patents – on his first ever visit to India. And then there were people there at the talk, who were asking Stallman how they could detect if someone has used GPLed code in their own software, maybe after modifying it. How they could track down these people and bring them to court. And there I was, wanting to ask the exact opposite – about how I could be protected for using GPLed code because there was no other obvious way to do something esp once you have seen one approach that solves the problem. The question about who protects the programmers.

My question never got asked.

People around me told me that my concern was unfounded. Things like that don’t happen. Nobody is bothered if you take from GPL code they said. Its just there to be a moral standard they said.

Last year, for some uncalled for reason, the topic came back again. This time over train ride home to Cochin from Bangalore when I was traveling with Sidharth. He didn’t see the problem and I was going on raving from the Karnataka border to Ernakulam railway station that its getting dangerous that there is so much GPLed code out there just lying around on the web, crawled by search engines and popped up at you without your ever intending. And if you took from these – copy paste from your browser that smart little three line snippet – you are strictly speaking, subjecting yourself to illegal usage of GPL code.

Over the years also I have developed this habit in programming when I am stuck I usually search the web for a solution. Maybe a smart little hack or a piece of advice on how to do something and I am chugging along smoothly again. After joining Microsoft two months back a few colleagues here advised me against doing this – you never know the legal implications of what you are doing they said. It seemed a little odd then, but then maybe I had been forgetting where I was coming from. I do use the web a lot – but now with this additional fear factor and layer of caution – and I wished I lived in a world where ‘freedom’ was a different, more real sort of freedom of choice.

Then I found this article : http://www.icsharpcode.net/pub/relations/amatterofinspiration.aspx

I do not know who is right and who is wrong in this debate, but I can empathize with the factors that caused it to originate. This is from the group that creates the rather well know .Net IDE called #develop – an alternative to VS and commercial IDEs and is often recommended to students…

I had been procrastinating making this post for some days now. Esp Chris Pratley’s words ring so close to my fears “I've been a little gun-shy of blogging about Word for fear of being inundated by what are as far as I can tell a gang of "net thugs" who roam the net making...”. Hopefully this will be the last thing I need to have to say about this entire topic for a while. My blog is getting increasingly dedicated to writing stuff that I get dragged into rather than stuff I like getting into.

DO NOT hold this in perspective of my employer or any previous employer or any other context - these are purely my OWN OPINIONS done on my own steam and is not nor was ever was part of any job description of mine.
