  1. Instead of blowing up ... on A Rock Moves In Space · · Score: 1

    Wouldn't it be possible to change it's delta-v to place it in a stable circular orbit around the earth? Why piddle with little tinker-toy space stations when you could have a kilometer-size rock in a stable orbit to play with to make a real orbital outpost?

  2. How to fight SPAM ... 5 points: on Anti-Spammers Wage E-War · · Score: 1
    Personally, I think there are 5 approaches we can take to fight SPAM. These approaches I feel are sustainable inasmuch as that they don't require you get an army of people to do work to get the problem of SPAM fixed. Filtering solutions are a nice short-term fix, but I don't think they will scale very well over time. Specially if you take into account the fact that SPAM is just growing geometrically if not exponentially.

    Approach #1: WhiteListing

    Whitelisting is basically the process by which your mail account is by default "closed" to all senders. You gradually give permission to certain people to send you Email thus creating a whitelist. The whitelisting implementations I've seen work this way: if you get an Email from someone you don't know, a warning Email is sent to you asking you to do certain steps to allow this sender to send you Email. If you agree, the sender is added to your whitelist. To me this is probably the most sensible short-term approach.
    Problem: Instead of getting innundated with SPAM, users will get flooded with permission requests. However if a whitelisting protocol is designed in such a fashion that all mail clients will deal with permission requests the same way (by moving the messages into a "pending" folder of some sort and by making it easy for the user to browse/mark senders as valid or invalid), it may be the best short-term technological solution.

    Approach #2: Legistlation

    Legislating SPAM away is probably one of the better solutions out there since you get to penalize monetarily the senders of UCE. Of course, this has to be a global (world-wide) process otherwise any SPAMMER could move off-shore to a nation that doesn't have SPAM Laws. This problem is fairly well known.
    Problem: Obviously, the wheels of justice turn very slowly and politicians can be easily bought by the private interests behind SPAM to counter the efforts of anti-spam lawyers. To replicate this effort throughtout the world may be a very nice "feel-good" thought, but in the end will probably be impossible to pull off.

    Approach #3: Make the SMTP protocol Secure

    The SMTP protocol is what, 30 years old? It really is time to improve the damn thing to make it so that the sender of the Email has to _somehow_ be authenticated. That is, the mail server must exist, must have a reverse DNS entry (PTR Record) and that the Email address of the sender itself (the mail from: received during the SMTP transaction) is checked against the sending mail server to see if the Email address exists. All sending MTAs should be validated and sloppy system administration should be no excuse in terms of having or not having a proper configuration.
    Problem: There will be heavy resistance from the mail server and mail client industry to improve the protocol on a global level. Furthermore there has to be some sort of phase-in period to give time for existing installations to upgrade their software so support for the previous incarnation of the protocol has to remain for an undefined period. It would be very expensive to do. If the expense is greater than the expenses caused by SPAM though, the industry as whole may not have a choice.

    Approach #4: Create an MTA reputation database

    Instead of changing the SMTP protocol, it may be that we need to create some sort of central MTA authority that would rate servers using a "reputation" scoring system. The more a domain or server is found to be a source of SPAM, the lower the reputation rating, at some point (threshold), mail would be refused network-wide at the connection level. Sort of an automated global RBL with teeth.
    Problem: Requires some sort of authority (centralized or P2P) ... don't know how it could be implemented but such a system would require global acceptance and integration into existing mail server software. Probably just as expensive as approach #3 to implement. Overall though, if the cost of the status quo is greater than the cost of implementing something like this, then at some point the industry as a whole may not have a choice.

    Approach #5: Require MTA certification

    This is the "HAM Radio" approach. Require that all Mail Server and mail service operators go through a global certification process for them to be able to broadcast using the SMTP protocol. HAM Radio is self-regulated more or less and it seems to work in terms of self-policing. Couldn't an approach like that be taken for "email broadcasting"?
    Problem: Requires tight cooperation between government and some unnamed agency that would represent all MTA operators. Lots of resistance would be encountered with such an approach ... this is a fuzzy idea and would require more hashing out by the community but what they hey.:-)

  3. Re:Replying to SPAM on Spam Increases Make Things Tough For Companies · · Score: 1
    Spammers operate off of huge lists of Email addresses that are harvested through various means: by going through usenet posts, by looking for Email addresses in "mailto" statements on websites, through "dictionary" spams sent to ISPs in bulk to see if messages bounce or not, so on and so forth ...

    The point is, alot of these lists have obsolete and dead addresses. When you click on one of these opt-out buttons, you're telling these shmoes that your address is indeed valid and someone is at the door.

    When told to "click here to get removed from our list" ... just say NO! :-)

  4. Extend the SMTP protocol for crying out loud. on Spam Increases Make Things Tough For Companies · · Score: 3, Insightful
    a) It's clear that a legal solution probably won't work since SPAMMers will just move their operations to more legally clement shores and the one-world-government isn't around yet to enforce anti-spam laws on a planetary scale yet .

    b) It's clear that a technological filtering solution is probably not the ideal way to go because ultimately, any filtering scheme doesn't address the issue that the SPAM is out there and it's still flooding our networks, regardless if you detect it as a SPAM or not.

    The only conclusion is that we really need to fix the problem at it's source. Change the SMTP protocol to include a handshaking/whitelisting layer. Is there a reason why the big mail server makers and mail client makers couldn't get together and work on an extention of the protocol that would make the protocol secure?

    To me, this is a no brainer and it's probably the only way to go at this point.

  5. Re:The problem is... on Spam Increases Make Things Tough For Companies · · Score: 1

    I really don't think trashing SMTP is the right idea. There's just too much invested into it to scrap it. It would make much more sense to work with the IETF to create a new RFC in consortium with various mail server and mail client makers to create an extention to the protocol.

    Personally, I think the best thing would be to add a new authentication layer based around the negotiated (handshaking) whitelist concept. It's really the only way at this point to (a) get only mail from sources you approve of and (b) if you do happen to get Email from someone out of the blue, be able to grant/deny permission for that Email to come in.

    So by all means, change SMTP ... but it should be a big chunk of the mail client/server industry that takes responsibility for the change.
