Just because A and B are correlated and A happens before B in time, doesn't mean that A is a cause of B. The tendency of medical researchers to make such assumptions is killing people. For example we now know that the women who had HRT (Hormone Replacement Therapy) were a healthier set of women than the ones who didn't choose to do it or didn't choose to continue with it. However the result was that women who took HRT had less heart disease. So naturally the medical researchers (often paid by the HRT manufacturers) announced that HRT was good for health. This increased the number of takers. But a double blind trial then showed that HRT actually causes disease and reduces life expectancy. The alcohol story is the same. People who like a drink have a pretty good toxin-handling system and so live longer than people who find drinking disagreeable. Yes ethyl alcohol is toxic: why else would men engage in competitive drinking. Needless to say my explanation is just a guess: there are various other ways that alcohol consumption and better health could both be caused by some other factor.
Why can't they do this to keep track of passengers waiting at airports. I'm so sick of waiting in the plane while the announcement goes out "Would Mrs X and Mr Y please go to Gate 42 where your aircraft is ready to depart". Meanwhile the passengers are off finishing their coffee and saying "Ha ha they can't depart without us because our luggage is on board".
To be more explicit: (1) mkdir --mode=og+x-r ~/public_html/private/ Apache can't read this directory but can access specific files in it. (2) mkdir ~/public_html/private/xyzzy/ where xyzzy is any random password. Put the files you want to transfer in that directory and retrieve them with wget.
The existence of intelligent life does require the universe to be large and complex. The multiverse interpretation demonstrates a related point: the probability of intelligent life arising in this universe might be low, or even very low. You don't need the multiverse interpretation to work this out, but it does make it a lot clearer. The ET searchers often express the assumption that our existence shows that intelligent life is likely to have a probability greater than one (because here we are). The fallacy that the size/complexity of the universe (which came first) caused intelligent life (which came later) is an easy mistake. You really need the multiverse interpretation to see that it is a selection effect fallacy. Note that the multiverse interpretation doesn't have to be "true" to fill this role, just one consistent way of looking at the issue.
Erlang (www.erlang.org) is open-sourced sw that Ericsson use internally. This has a "production quality" DB called felicitously mnesia. It has failover, replication, very easy to use transactions,... It's not relational but the programmer's interface is very easy. There is an rdbms front-end advertised in the erlang contrib area - don't know how good that is. Erlang deserves to be better known: it is one of the biggest and best open source projects.

The bug that affected tikiwiki and sometimes slashdot seems to be fixed. This makes it much more useable. Kerberos auth also important.
qemu seems to do emulation right. It would be nice if the emulation community would get behind it.
To be more explicit:
(1) mkdir --mode=og+x-r ~/public_html/private/
Apache can't read this directory but can access specific files in it.
(2) mkdir ~/public_html/private/xyzzy/
where xyzzy is any random password. Put the files you want to transfer in that directory and retrieve them with wget.
