Yup, the whap, whap, whap helicopter noise comes from the blade moving in front of the mast, where the air flow is disturbed. So, more distance, less disturbance, less periodic noise. One can buy ready built wind generators from marine yacht shops, but they are horribly expensive. Using car/truck cooling and electrical parts is far more economical as a DIY project and the parts are readily available. A custom made thing ties you to the original supplier and their high sticker prices.
For example, while a direct drive alternator is nice and simple, a pair of pulleys with a v-belt driving a truck alternator is much cheaper.
In my experience with charging a battery for a cottage, the KISS principle is paramount. I eventually settled on hooking two 15 inch 12V cooling fans in series, with a big diode to charge a 12 volt battery: http://www.flex-a-lite.com/auto/html/chevy-diesel.html
Two posts, two fans, one diode, one battery and a volt meter so you can unclip the charge cable once the battery is full. Put a connector in the down cables so that you can unwrap the cable once a month (they don't go round and round all that much, so no slip rings are required). I think if the wind speed at your place is very low, use three or four fans wired in series to get the voltage up. A series stack of generators is much better than investing in complicated charging electronics.
Use of off-the-shelf car parts is still the easiest way to generate small amounts of wind power and efficiency doesn't matter. Time and cost matters.
Well, the simplest way to build a wind generator, is to buy a 3 foot diameter 36V cooling fan for a large stationary diesel motor and mount that on a post. Add a big diode and hook it to a 12V battery. If you are a bit more careful, then add an over-voltage cut-out switch. To power a sea/lakeside cottage, this is all you need. A 36V fan will charge a 12V battery better in low wind (It won't ever get to 36V, not even in a storm with no load).
The post bearing is just a pipe slid over the mast, it can be a loose fit, add some grease to eliminate squeaks, add a vane at the back and run the cable down loosely with a plug, so you can unwrap the wire once a month.
KISS.
In general, a set of self clearing timed rules based on heuristics require less maintenance and mistakes are mostly self correcting. Hard RBL based rules put you at the mercy of whoever compiles the RBL and mistakes can linger for a long time. One issue being that you cannot even tell whether there is a mistake if connectivity is completely dropped for example.
It makes a lot of sense to use the Spamhaus RBL to block things in a firewall. If a site is black listed for sending spam, then I don't want any traffic from that site, not email, not web traffic, anything. However, I am not aware of a system that ties an iptables DROP rule to an RBL.
Well, you know, Microsoft did not have to change their device driver model. If they kept that the same, then all drivers developed for Win2000/XP would have worked. MS deliberately created a borked system and is marketing it is the best thing since sliced bread. They deserve all the bad press they are getting. At this point in time Vista is an expensive POS.
People who already bought a disfunctional Vista should install Mandriva Linux, but if they are really locked into Windows already, then the Pirate Bay is a good solution for a copy of ExPee.
Unless they count a UPS, RAID and tape drives as security, there is no way that security can eat up that much of the budget, except maybe if the surveyed all use Windoze...
Hmm, I ran an original RedHat Linux 4 machine as my mail server from 2002 till a few months ago on a Celeron processor. That was kernel version 2.0.18 I think.
It rebooted once a year when the server farm did PSU maintenance. There is something to be said for leaving well alone, or don't fix it if it ain't broken!
Hmm, consider that most satellites are just 'bent pipes' in that they simply transpond whatever gets to them and sends it back down again, then it should be quite feasible for you to put a dish in your backyard and intercept your wife's van signals...

Just randomly drop 50% of packets going to/from Russia... ;)

That has been debunked as a hoax unfortunately.
Nice. Although I would prefer a packet mirror rather than a black hole. Just route packets coming from the DROP list back to itself.

I guess the guy in ChaCha used Google and the others were too dumb to do that.
Well, most people run Windows and attributes any crash to Microsoft, not memory errors.

Vista also loses value the moment it is carried out of the showroom.
...but is it still top down in Australia?
"we will "loose" a lot of words"
;)
Why would the words fall apart? I guess you already lost "lose"...
...and the borogroves all slithy in the wabe.

"1. Microsoft actually gave a shit about any protocol"
There, fixed it for you...
If this makes it more difficult for idiot spammers to send idiot spam, then I cannot really say anything against it.
Yup, the difference is that Mandriva is based in Europe, where the inclusion of these things without legal controversy.

When? A few years ago...
Why don't you try Mandriva 2008? It has wizards for everything - ideal for the pointy-clicky masses.
Pretty soon, MS Vista will be the only thing left that is ruined by DRM...
