    I've seen how big and heavy the UPS bricks are to keep a 500W computer running for 10-30 minutes, and those cost around $100. CNN says some areas could be out for days to over a week. What does it take to power a tank for that long?

    Depends on what powering a tank means. In the Winter running heaters it might not be reasonable, but then again you don't have to run a heater at all if you cn keep the room temperature at a safe temperature for the tank (fireplace, woodstove, or k-1 heaters, and your survival is likely as important to you as that of your fish). But now (or for my friend in Arizona) heaters are not an issue, just running a filter or even an air pump. I don't expect the filters draw much, but one should check the rating on the pumps to be sure. The fish can live quite a while without filters though (the issue to my friend was keeping water running through the filter so the helpful bacteria built up in it would not die, but that wouldn't be a complete tragety). For air, if the tank is not overloaded it's no problem at all; I could kill the filter in my tank and the fish would be fine. But many people put more fish in a tank than it's surface area can support. These people need to run some sort of air pump to keep the tank oxgenated, or a water pump to increase circulation and oxygen exchange. But these little air pumps draw only a few watts, and I expect even a small UPS would keep them running for days. I do know these little UPSs will run for days will minimal load; I have one on my TV, Stereo and VCR (no more flashing 12:00). In an ice storm last year I watched TV for about 45 minutes after the power went out, then turned the set off. The UPS kept running and retained the VCR setting for about 4 days, and it's only a 300 VA unit (about 225 watts). It clearly could last a lot longer if the batteries are not drained by TV watching.

    Heaters are usually rated directly in watts, so that should be easy (tricker is that the "Volt-Amp" rating of most UPS's is not watts, even though P=IE, but they usually have a watt rating on the box too). Don't forget a heater will not have a 100% duty cycle, but the UPS must be able to supply the current the heater needs. Motors should not be a big draw, but one should check their pump. Overall if you're expecting the UPS to keep your fish warm you might be asking a lot, but that's hardly today's problem. And the friend I suggested a UPS for is in Arizona, was only concerned about power outages affecting the pumps. By the way, I had a power outage this winter for about 4 days and didn't lose any fish, but the tank isn't over capacity so oxygen exchange was still fine, and I kept the house warm enough with heaters and the fireplace so the fish didn't die of the cold. I expect the original poster on this topic had way too many fish in his tank and knew they were going to die from lack of oxygen, not from lack of heat.

    Why is this rated Funny?? I suggested exactly this to a friend who has a large tank and was expressing concerns about power failures just a few weeks ago. She was mostly concerned about the filter shutting down long enough to kill the bacterial from lack of water flow (I think her estimate of how long this would take was very conserative, but the concern about the issue was real, and it certainly can happen, it's just an issue of how long an outage is required). Contrasted to other expenses involved in a large tank, a UPS is an extremely reasonable investment.

    I suggested that the microcharge would only be incurred if the recipient didn't have the sender on their TDMA-like whitelist. It's opt-in with teeth.

    And give the micropayment to the recipient, for all I care.

    Realistically, a legitimate mailer can not count on all (or even most) of the people who have requested that they be put on a mailing list (or otherwise supplied an e-mail address for a valid reason) will have added that sender to their white list. Heck, your "give the micropayment to the recipient" virtually gaurantees that, the effect of not adding them to your while list would be that you still get the mail you wanted and you get paid. But even if the payment went somewhere else, lots of whitelists wouldn't be updated and it would still have enough of a negative effect on legitimate uses of e-mail to kill some good valid uses. Why not just fix SMTP or replace it with something that is spam resistant? There are a lot of things that can be done to improve SMTP that cost the users nothing, and I believe most users would quickly adopt spam resistant mail systems.

    Consider the following changes: Make the sender store the outgoing messages on their system until picked up, with only the header being sent as the initial message. Make sure the sender provides a real and valid reply to or other contact address (as the above system does), and maybe even tie that into geographic locations (preventing US spammers from sending through China or Argentina, or at least giving recipents an easy way to block such spam).

    No, I completely understand that. While I said that Bayesian filtering is completely ineffective when installed on your system rather than on the ISP system, I didn't advocate installing it at the ISP, I don't think an ISP based filter will be very effective, and I think there are better ways to fix the problem by moving away from the current version of SMTP and by passing laws that let the spammers face very high fines (or worse).

    You clearly miss my point that when you filter only your mail you still let the spam reach the people who will buy the product. But you also seem to think the filter has any effect on you at all. Yet most filter advocates claim they don't want an ISP filtering their mail because they fear false positives, and say they send all of their filtered mail to a special spam inbox so they can checj for any false positives. These people still end up examining every piece of spam they get in just as much detail as they would if they were killing it in their regular e-mail, the only real change to the system is that they put that work off until later, and in doing so they also may delay receiving anything that was a false positive until later also. There is n net gain at all with such filtering.

    Whereas I sent out about 2000 messages last year, so I'd only have had to pay $4 for the whole year, even if 100% of my messages were "unwanted". I'd pay $4 a year to make SPAM go away.


    Micropayments would in no way stop spam, but they would cause cost and problems for honest users.


    Where would those micropayments go? To the ISP? The one that is providing a haven for the spammer? To the spammer itself when it is acting as it's own ISP. In either case the micropayment would be a farce, certainly any service provider who is working with a spammer could wave the micropayments if they are already letting a spammer on the Internet in the first place.


    But more importantly, micropayments will ruin some current valid used of e-mail and prevent some future ones. Think of the many mailing lists that are run by very low budget groups to communicate with hundreds or thousands of members. These would be destroyed if each time they were to send out a message to all members they invoked a micropayment on every single e-mail. Heck, Slashdot sends me an e-mail when someone responds to one of my posts; how long do you think that nice service would last when Slashdot started to have to pay a micropayment for every single response that was posted??? I would certainly see that this would completely kill any new uses of e-mail as well. Imagine a school that was considering using e-mail to keep the parents more current on their child's ststus; perhaps weekly or even daily report cards rather than end of the quarter suprises. It would be a system welcome by many partent, and could be easily done if integrated into an electronic grading system, but would be killed instantly if there were a unit cost on sending e-mail, even a small micropayment. There are lots of other useful things that e-mail might do for us in the future; do you really think we should give them up an adopt a payment system that really isn't going to stop spam in the first place?


    And I still maintain that it will not stop spam, even if the payments are not to the original ISP. Many spammers manage to inject their spam into the net through badly configured servers or other exploits. While I'm all in favor of making someone who improperly sets up a server pay for letting spammers have a doorway to the net, I'm not as likely to advocate a system that encourages more trojans and backdoors so that spammers can pass their costs on to unsuspecting in-duh-viduals. There are simply better ways to fix the problem (by changing the fundamental flaws in SMTP) than by approaches that will harm valid e-mail uses.

  13. Re:Authentication of senders on Comparison of Bayesian POP3 Spam Filters · · Score: 3, Interesting
    The only thing that can truly save email is to switch to a service that requires authentication of senders.

    I agree with everything that you said about filters being ineffective. But I strongly disagree with your "only thing" statement. Particularly if you mean it as any of the systems I've ever heard about, such as "If it's not in the address book, the sender must acknowledge a challange message" type of approaches. The problem with such systems is that many of us get quite a bit of e-mail each day from people who are not in our regular address books, some of it quite important to us. We do not want that mail lost because the system at the other end was not in out address book and did not waste their time responding to a challange and response type system. For example, say I purchased something on-line from a vendor I had never dealt with before. Their e-mail system may automatically kick out an e-mail that informs me the product was shipped and give me an important Fed-ex or UPS tracking number. I'm glad they do such things with their shipping systems, and I don't expect them to manually respond to every challange they get back; realistically they will send any such challanges to the bit bucket and people who want e-mail that is important to them will end up never getting it.

    So I do not believe that Authentication of senders , at least in any of the traditionally suggested ways, is the correct approach. Much of the spam problem we have is due to what I consider flaws in SMTP. I would very much like to see a replacement for SMTP that considered the spam problems (as well as other problems inherent in SMTP). As an example, another post here mentioned a system where the mail is held, not on your ISP or upstream provider's system until you download it, but rather is held on the sender's or sender's ISP's system. The recipent would presumably receive only a very short indicator of where they have mail waiting, and would fetch it themselves when they are ready to receive it. The puts the burden of storage on the sender or the service provider for the sender, and avoids considerable bandwidth wasted by senders who supposedly send out e-mail with addresses generated to match all combinations of up to x characters (the excuse Mindspring gave to me when addresses that I created but never gave out or used started getting spam, not that I believe them). In addition to putting this burden on the sender, it would insure that there was a good address in the e-mail to fetch the mail from, so spammers would have a much harder time injecting their spam into the system and would be much more traceable. And while I'm not foolish enough to think that laws could completely stop spam, we've seen how laws did drastically curtail fax spam, and some fax spammers have recently been made to pay serious fines. I do think laws would have a big effect on spammers; ther are a lot of spammers who just don't want to have to move out of the country to keep up spamming, and those of us who hate spam will track the spam back to US sources if we have a law with teeth in it to impose fines (or worse) on them when we do.

    Of course, and change to or replacement of SMTP must be phased in over time. It's not a short term solution to spam. But I expect SMTP would quickly go the way of gopher or archie or the rest if a viable new protocol was presented that addressed these problems effectively, and this is where I think out greatest chances for sucess are.
