Never mind. I just read the original article, and realized that the receiving MTA would query the domain, not the IP owner for whether it (the IP address) was authorized to send mail on it's behalf.
The only problem that I see with this is that ISPs aren't always willing to delegate lookups of in-addr.arpa subdomains for a single DSL ip address. I run about 5 domains from my single DSL ip address, and my dns server will serve up both forward and reverse lookups for my domains, but since my ISP isn't delegating the lookup of my ip address, no one will ever ask my server what hostnames go with 64.136.146.65 (65.146.136.64.in-addr.arpa). Since I'm moving soon it hasn't been worth it to find an ISP that would delegate.
But when everyone stopped driving/biking/pogo-sticking east, the earth would speed up again:-( Perhaps we could all shine our flashlights/lasers/ion-beam-weapons toward the east instead.
But if we do slow down the rotation of the earth, the day needs to be defined as more than 24 hours, because spending 8 hours at work now is killing me, if the hours were longer, I'd have to go postal:-)
I did forget the Superdrive, but the 12" doesn't have Gigabit Ethernet, only 100Base-T. I don't see the need for FW800 right now, given the lack of products supporting it, and I can't imagine using at 12" hooked up to a FW800 Raid Array. If I'm doing such heavy lifting, I'll use a Desktop. I see the 12" as a great travel machine, that can do video well, but that if you're doing it professionally, you are going to want a higher-end machine. The ram issue is a bigger one. '640MB should be enough for everyone':-), but having to throw away 128MB to raise the machine to a usable configuration (512MB) seems silly. I suppose a memory limit of 1GB could help some people, but as I said before, I don't see that the difference between 640MB and 1GB is a big deal where this machine is marketed.
Reasons for a 12" powerbook over the iBook, if you have money to burn: G4 (Altivec for media stuff) Supported monitor Spanning Airport Extreme (54Mbps vs. 11) Bluetooth (if you've got the other BT toys)
So, certainly there are other reasons than simply monitor spanning to get a Powerbook, though I really considered the iBook for my wife before I got her the 12"
It's possible to raise the cost of sending an email so that for typical email senders, and even mailing lists the cost isn't prohibitive, but because of the 1% response rate to spam would make spamming a losing proposition...
The problem is updating all the MTAs, or worse all the clients at the same time. If you continue to receive mail from older MTAs or clients which don't know how to sign or 'add postage' to an email, then the spammer will just pretend to be the older MTA/client...
So there's a huge resistance to upgrading the infrastructure. Until everyone is upgraded the upgrade is basically useless, which means people don't see the need to upgrade, which means it never happens....
Having sailed (on a sail boat) from Hawaii to San Francisco, I can assure you that slipping into San Francisco with a nuke would be quite easy. At no time were we approached by any authorities when we sailed in, and we sailed right into the marina at the foot of the Bay Bridge.
Well, it costs more than $99/year if you want to have 500+MB of mail in your IMAP folders (like I do at home), or if you want to have more control over your website (cgi, or zope...), or if you want to host your site at a certain domain name. Plus, doing the work yourself teaches you skills which may increase your employability...
What I do is have my work machine ssh to my home gateway, and my 'local' work machine forwards port 2080 to my 'tivo.thille.org' machine inside my firewall at home. Then on my work machine, the url is something like 127.0.0.1:2080/...
The only outbound port needed from work is port 22 (for ssh), because all the traffic is carried, encrypted, from my local machine inside the firewall to my home gateway/firewall over ssh. It's only at my home gateway/firewall that it's unencrypted and untunneled and forwarded to port 80 on my tivo.
Read up on 'hashcash', basically, you combine a whitelist setup with the hash-cash setup so that unsolicited emails can still get through, if they have the hash based 'postage'. Mailing lists get through because they are on your whitelist.
Of course, there are things like TMDA which is a whitelist managing MDA that sends confirmation emails back to the sender if the aren't on the whitelist. This is generally enough to stop spam.
Well, my wife has a ton (~200) VHS tapes that I'd love to put on VCD just so they'd take up less space, physically, but they won't fit on 1 VCD and she doesn't like the 'think of it as an intermission' answer...
Right, it's just conceptually 'easier' to understand, but the last paragraph of the application talks about having to move the mouse pointer to the horizontal scroll bar to 'select' horizontal scrolling mode for the 'scroll disk'.
I think the best thing about the scroll disk instead of the vertical scroll wheel most mice have is that you get continuous scrolling by moving your finger tip in a circle, not pull finger tip back toward you, lift, move forward, lower finger to wheel, repeat.
That said, the IBM scroll-point mice are probably just as good (haven't used one though).
I suppose a spring loaded pressure sensitive disk would work too. You don't rotate the disk 360 degrees to scroll, you pull it clockwise against a spring, and that causes continuous scrolling until you release it...
The Internet grew out of a DARPA project, right? So, the RIAA should go up against the whole military-industrial complex. I want to see that contest...Talk about Shock and Awe!
But what if you just pretend to be someone visiting from another country? You certainly wouldn't be required to have a Belgian National ID card then, right? Would they lock me up for a long time if I were to be an American Tourist walking around Antwerp without my Belgian National ID? Note that I tend to leave my Passport with my bags (safe in the hotel room).
If you read Dawkins, you'll see that a 'superior gene' is one that reproduces better. After all, that's what the gene is trying to do at the basic level. "A zygote is a gamete's way of making more gametes. This may be the purpose of the universe" -L. Long:-)
Note also that $24 of the $44 was _SHIPPING_. The TX/RX modules should be available via a local distributor, though perhaps at a higher price (They seem to be made by Velleman: http://www.velleman.be/Product.asp?lan=1&id=18729, who lists Fry's and Marvac as distributors in California). Super-bright LEDs might have good prices on the LEDs, but if you only need the 6, it's probably not such a good deal counting the $5 in shippping. PIC's should also be available locally, saving the other $6. The Taplight runs $2 each if you buy the set of 6 to which he links. the PIC programmer is the most expensive thing in the project, but it's not a consumable, and it's something someone who cares about hobbist electronics will probably want anyway...
Yeah, because in police states people can be held without access to a lawyer, or without being charged with a crime, 'because the government says so'. Oh, wait, we've got that here...

Yeah, there's a great story about a guy trying to buy his burrito with a $2 bill here.[google cache]
Yeah, right. Like you can't scale things in Photoshop or the Gimp? Where've you been man? This is the digital age! :-)
Of course in my world, '1' is -27v and '0' is +40v.

You should just start using the junk mail to heat your house at that point...

Yeah, but it was new back then, so he pronounced it 'nanu nanu'.
So I downloaded the film from the net...

That's because Microsoft enhanced 'su' to be 'sue' :-)
