I've always wondered if someone `famous' used Linux. Someone you'd know from TV or movies.
Also, I wonder why women don't seem to get into Linux or `the community'. Girls are usually a lot more social than guys, so it would seem that this is a really screwed up world we all live in. Then again, the girls I know are highly susceptible to gossip, which can easily destroy social circles..
Hmm. I used `girls' instead of `women'. Blah, I'm not feeling PC today.
Anyway, I'm currently trying to do some wacky NFS sharing that is going to involve mounting loopback filesystems and other weird nonsense. There's probably another solution which is easier, but I haven't found that one yet.
Well, the loopback filesystem trick actually works (the problem was that the disk being shared didn't have enough space left, and it was supposed to be pretty much an exact mirror of another system. Symlinks to another filesystem don't work all that well with NFS, but maybe I could have still found a way..). Never thought I'd find a real use for loopback devices (other than viewing ISOs that haven't been burned and whatnot..). Then again, I guess a loopback fs is an important part of those bootable business cards, among other things.
Spent much of the afternoon mucking with TCP Wrappers on Solaris. Some of the daemons just don't want to run from tcpd.. Annoying..
I see that there are versions of tcpd that support IPv6. Might be fun to play with.. I've been interested in IPv6 for a long time, but it's only now really getting any use on the Internet at large. Debian 2.2 supports it though. Hopefully it will finally start to displace IPv4.
Kind of along the lines of why we need IPv6, I'm always scared by the DSL and Cable modem setups where you essentially get 25% efficiency WRT addresses. The lower number is the network number, the higher is the broadcast. The two left over are gateway and client IP. Scary..
And this brings me to a question I've had for a long time -- is there a system for NAT in IPv6? Ideally, this won't be necessary, but we all know that the service providers will only want to give you a single address if at all possible, meaning that they can bilk you for cash if you want more than one computer on your connection..
Annoying companies..
It's raining, and I'm getting interested in how Free Software can be used to distribute weather information. There's a system called EMWIN that I've looked at before, but I don't have the time/money/hardware to play with it. The best way to get info right now is probably to have a satellite downlink. They have a moderately powerful transmitter up there, so the dishes only have to be 2-3 ft in diameter. Not as small as the digital satellite TV dishes, but not exactly huge.
The important thing is that you can get real-time or at least close-to-real-time data, which is often better than what you can say for most of the current Internet sources. With EMWIN, you can get notified of watches and warnings at the same time as or earlier than your local TV and radio stations. Weatherguys.com is largely powered by EMWIN data.
At any rate, I have been wondering if the National Weather Service will make at least some radar data publically available on the Internet after some contracts expire at the end of next month. It looks like they have defined the layout for how things will be on their FTP server. This sort of thing is a prime candidate for mirroring and multicasting.
