Proper Fixation always had more unfinished drafts than posts, but recently it's getting ridiculous. I do have a couple of drafts I seriously intend to finish (usually the drafts which don't make it to posthood during the first 4 hours or so go to the eternal drafthood land.) Until I'm able to think this stuff out to the point where I can share the results of my thinking, I figured I could share the far less scarce resource of Wisdom with ya.

Since I've violated the Golden Rule of Helping Friends with their PC Problems and attempted to help a friend with his PC problem, expectedly wiping out his hard drive in vain, I had many opportunities to explain the Programmer Paradox: how can a programmer fail to make a computer do as he wishes? While the difficulty of debugging a program without the source proved hard to explain to laymen, I think I've found a metaphor that does a good job. A programmer is to the blue screen of death what Mikhail Kalashnikov is to a loaded AK-47: just as helpless a victim as any other mortal, except for having a profound understanding of the mechanisms of his execution.

I would like to get some statistics on file encryption. For example, of all the files on the planet, X% are encrypted. Of all those files, Y% will never be read by someone due to encryption. Of all those files, Z% will never be read by malicious intruders. If I could lay my hands on the value of just one of these unknowns, I'd pick Z, because at least 100-Z% of the files will never be read by their owners. I would bet on Z lying somewhere between 0 and 1.

One of the key traits of good code is the ease at which it can be modified. One of the key traits of bad code is the high cost of modifying it. So good code is likely to deteriorate until it's bad enough to become hard to change, and bad code is likely to stay bad. In short, code has a strong tendency to end up bad.

This can sound worthlessly pessimistic, similarly, for example, to "It is easier to break a leg than it is to cure it, therefore, most legs end up broken." However, I think it's more analogous to aging – the accumulation of changes in an organism, observably causing most animals to end up dead. Similarly, code that is used will be changed, code that is changed will degrade, and code that degrades beyond a certain point will die.

Health tends to be simpler than disease. For example, everybody can brush their teeth but few people can treat cavities. Similarly, it's not very hard to maintain a sane development environment, but pretty hard to deal with the tide of bugs and of long-living branches resulting from a failure to do so. However, I'm generally optimistic about the chances of such cavities to be treated, and as usual, the optimism is based on the pain they cause – a strong incentive to seek and reward treatment.

There's this evolution vs Intelligent Design debate. Well, I don't know about life on Earth, but I sure have hard time believing in Intelligent Design in software. Code has to repeatedly survive exposure to users upon whom its fate depends. Yes, "users" can be a set containing just the author, but only if it's honest-to-God USAGE, that is, the author has to pay a price when the program is hard to use – like not getting important things done properly. Show me a program that someone finds useful and that wasn't subject to such evolutionary pressure, but rather was Intelligently Designed as useful.

I think that my intense hatred of the word "design" has to do with its prominent place in the speech of software creationists. These people are likely to constantly complain about not having enough resources to do The Right Thing in the ugly real world. They are also likely to give you software that you hate enough to wish to kill them, and be articulate enough to convince you that the problem is at your end, and fail to notice how this latter ability quadruples your desire to slash their body into square millimeter pieces.

I'll conclude with an off-topic request: if you know a good text advocating a collectivistic or other kind of heterodox approach to economics, I'd be very grateful for a reference. By "advocacy", I mean a text for laymen expressing support for a certain set of policies (as opposed to merely criticizing the effects of existing policies) – like Milton Friedman's "Capitalism and Freedom", for example.
