According to a report from Gartner group:
In 1997 they estimated that there were about 300 billion lines of computer code in use in the world. Of that they estimated that about 80% (240 billion lines) were in COBOL and 20% (60 billion lines) were written in all the other computer languages combined.
I don't consider "lines of code" to be a particularly useful metric, but regardless, it always amazes me to be reminded how much COBOL is still in use.
In actual game dev news, i've been looking at Inform 7. A few years ago I wrote some small interactive fiction games with Inform 6, but the new version seems to be something completely different - a natural language approach to a programming. I don't have much motivation to work on an interactive fiction game these days but i'm going to play with it a bit.
I've also put over 40 hours into Disgaea 2 over the last 3 weeks. That's about 2 hours per day on average. I'm disgusted with myself, that's a lot of free time gone. The sad thing is that i'll probably stay at that pace for at least another week or two - i'm enjoying it too much.
