  1. Re:Grey Listing and zen.spamhaus.org on Ask Slashdot: Speeding Up Personal Anti-Spam Filters? · · Score: 1

    Please stop roleplaying someone stupid with your current game of presenting the incorrect suggestion that the greylisting time set on the recieving server doesn't matter.

    Unless you are insanely stupid and use a greylist wait of a couple of hours, it really doesn't matter. Typical values for the wait are in the sub-5 minute range. Since it's resource intensive to retry at intervals smaller than about 5 minutes, good client configurations aren't going to even get to the first retry until after the greylist wait has expired. But, based on my own logs, you could set the wait to as little as 10 seconds and still have an extremely effective front line defense against spam.

    Once an IP passes the wait successfully, e-mail from that address isn't ever delayed again (although I personally set a 40 day timeout on the whitelist to account for dynamic IP addresses). Add in the ability to pre-seed the list with known-to-retry systems (gmail, Yahoo, Amazon, etc.) and known common senders to your domain, and most people really will never notice any delay. And, if you run for about a month in "log only" mode, you'll get a great starting list of IPs you might need to whitelist. And, you need to think about server farms, so you might want to accept a retry from the same /24 subnet (which is what I do).

    Also, if you were dumb enough to greylist mail that came from your internal network (which is the only way that a greylisting config would cause your boss to ask "why doesn't X have my email yet"), you don't understand greylisting enough to be in a discussion about it. For external senders (who should never be asking you that question, anyway), you can always explain the reason the e-mail is delayed: whoever configured their e-mail server didn't feel that a quick retry after a temporary failure was required.

    So, this might be flamebait, but what it really comes down to is that your issues with greylisting were likely because you didn't do your homework and create a config that was as non-intrusive as possible.

    With the exception of the Super Bowl (where commercials are sometimes worth watching), I haven't watched a TV commercial in over 20 years. That's a small exaggeration, as until the advent of the DVR, I did see commercials on live sports, but other than that, I've recorded everything I wanted to watch.

    In the late 80's, I had 4 VCRs (all with a 30-second-skip feature), and each was programmed for the shows I wanted to watch. When a tape filled, it was ejected and put onto the top of the "to watch" pile. Friends and roommates all seemed to understand the system, and nobody cared about watching shows on the day they aired.

    I used to have two dual-tuner TiVos, but now I have a 5-tuner DirecTV DVR. I don't actually watch much TV, but there are times when the shows I like are all on at the same time, so I need the capability of that many tuners. I now watch sports by recording and starting to watch about 1-2 hours after the beginning.

    DVRs make my choice of how to watch much easier, but the technology to not watch commercials has been around for nearly 25 years. If you weren't using it, that's your loss.

    I've responded to quite a few ACs who claim that OTA has a lot of sports, but none have ever given concrete examples to support their claim.

    There are some cities in the US where you have a reasonable number of sporting events per week on OTA TV, but those are very few.

    Even some relatively major cities (like Washington, DC) have no real OTA sports available. The Washington Redskins are the only sports team in the city where a significant percentage of their games are available OTA, and that's because there is only one game per week and the NFL specifically allows a local station to show a copy of games that are shown on cable stations. If you like hockey, baseball, basketball, soccer, golf, or even tennis, you will get at most two games/matches/rounds per week via OTA. It's even hard to find local college football reliably via OTA.

    "No True Scotsman" involves moving goalposts. Alcohol abuse is a well-documented, well-defined medical condition; the only "goalpost-moving" here is movement from the OP's self-diagnosis.

    Which is the whole point. You just moved the goalposts from "alcoholic" to "alcohol abuse". I've known many people who would qualify as suffering from "alcohol abuse" (by the DSM-IV definition) in college who stopped being more than "moderate drinkers" once in the real world. I also know people who don't fit the DSM-IV definition who absolutely would be considered "alcoholics" based on their daily intake of 6-12 drinks, but because there are no "recurrent adverse consequences", they don't fit the "alcohol abuse" definition. Basically, they get hammered after dinner, go to sleep, and wake up and go to work.

    If you define an "alcoholic" as "someone who can't stop drinking alcohol", then every substance abuse treatment for "alcoholism" has had a 0% success rate because everyone who is an "alcoholic" is just on a break until their next drink. And thus the whole point of AA is to replace alcohol with some other lifetime obsession, since nobody is ever "cured".

    If you then move the definition to "someone who can't stop drinking alcohol without help", then you have to define "help". Was it "help" when somebody refused to give the alcoholic money for the next drink, which caused him to sober up long enough to stay sober for the rest of his life?

    Many of these slight changes in definitions happen with no intent to "move the goalposts", yet they end up doing just that.

    This argument is getting tiring. I'm not sure what prices are in your neck of the woods, but according to the Toledo Blade on 7/22/1983 (http://news.google.com/newspapers?nid=8_tS2Vw13FcC&dat=19800722&printsec=frontpage&hl=en) it showed tickets as going $2.75-$3.50, non-matinee pricing. In 2013 dollars, that's right around $7.50 - exactly where a ticket for a non-matinee show is in this area. Sure, in a bigger city, it might be $9 or so; I'm not going to check it for you what the price was is 1983. It's reasonably tied to inflation.

    The difference is that in 1983, I couldn't wait two months and watch it in my home with better sound and picture as good (albeit smaller) for around, all for about the price of two movie tickets. And, for that price I would own the movie, and could watch it as many times as I want.

    That makes the current prices a lot higher psychologically, as you are basically only paying for the ability to see the movie sooner, and it might just be an inferior movie compared to the home video version. For example, the director's cut of Cowboy's & Aliens was far superior to the theatrical release, with much more backstory and exposition. Other movies might not differ as much, but you still likely get more for your money for the home video version, including commentary, making-of, etc.

    Yes, that's precisely the point. They are trying to sell you "one word'.

    They do this by picking the words first and not allocating them to a location until you click "share". If you don't like the words, you can "share" them while pointing to a location you don't like. Then, you get another set of words.

    So, there's no magical algorithm at work here...it's just a random number generator, and once someone writes an app that "shares" some random location until the words that come up are within some target set, and then fixes that in place on the desired location, their whole business model of selling words goes down the drain.

    Even worse, the system will be gamed until every three word triplet will be assigned to someplace, and then the service is completely useless. Doing the math shows that they'd need 39,000 or so words in their pool, and although that's far less than in the English language, they need to use words that are easy to spell, not easy to confuse phonetically, and common enough for people to know them.
