You might be right, some places do need quick turnaround times on email, but the trouble is that this is never guaranteed even without greylisting.
All be businesses I know wouldn't notice a 15 minute delay on the first email from someone they never had any contact with before, but it's a solvable problem, in the long term anyway.
What I think is needed is a global whitelist (based on cryptographic signing and web of trust) that allows servers to bypass the greylisting, that way you can choose between getting your mails delayed a bit and getting a certificate, both cheap and easy to do.
Most spammers seem to hit a number of spamtraps with each zombie at some point, so using spamtrap driven RBLS in front of greylisting means that the RBLs will take care of the verified spammers.
greylisting gives the spamtraps some extra time to get hit, so rather than do actual blocking itself it augments the RBLs.
1) Email has never been an instant messaging system, I've tried getting people to stop asking for an IRC/ICQ/MSN/AIM/whatever chat and just use email, but nobody listens.
2) Any mail server that doesn't retry when given a temporary failure code is broken and needs to be replaced, sooner rather than later.
In any case, I do review my mail logs (well I did the first two weeks of using the new system) and I saw exactly zero false positives.
The spamtrap driven RBLS I use all list and delist servers quickly, so they also cause no false positives, but if they ever do the user who sent me the unlucky ham will get a nice bounce message, so he will be able to retry the mail or call me.
I think getting bounce is much nicer than just having your mail eaten by a filter.
What you are doing to filtering, it is wrong because all it does (when it works) is to keep you from reading spam and cost you CPU time.
The bandwidth already been spent once the spam reaches your filter.
A much better approach (IMHO) is to use greylisting along with a few fast spamtrap driven RBLS, this way the mail doesn't even get transmitted to my server and I save both CPU, bandwidth and time.
Since I switched I have gotten a max of 2 spams pr. day, some days the count is even zero.
There are two reasons this approach is so great: 1) The greylisting on its own will weed out all the non-compliant MTAs, most spammers use zombies that don't care if their payload gets delivered, so they never retry. 2) The real MTAs that spam might get to me before hitting a spamtrap, but the greylisting tells them to come back a bit later, by that time they have hit one or more spamtraps and get blocked by an RBL.
I have yet to think of a way for spammers to defeat this scheme and the cost to legitimate mail is a 10 minute delay the first time someone sends me mail.
That way MS will have the maximum amount of suckage that have ever existed in one place.
I propose that this will form a singularity of suck, a black hole of sorts, which in short order will concentrate all the suck on the planet and keep it locked at the MS campus for all time.
You (and most people it seems) overrate how important this crack is.
Bluray and HDDVD use the 100% same DRM, what works for one will work for the other.
The only difference between Bluray and HDDVD is the additional B+ spyware/rootkit code which needs to be run in a virtual machine (I think it's Java) the only thing the B+ crap can do is to do further work before decrypting the title key, once that has happened the keys will still be in RAM, ripe for the picking, just like this hack.
What is needed before we can declare either format non-worthless is to get a player key and have a reliable method of finding other player keys.
The best outcome would be for both HDDVD and Bluray to fail miserably the same way as DVDA (snicker) and SACD failed clearing the path for a much cheaper and less restricted medium, like: http://en.wikipedia.org/wiki/Enhanced_Versatile_Di sc
If the EVD can become popular enough in China that all chinese made players support it by default (like VCD) and bluray/hddvd keep dragging their feet then at some point studios will serve customers with those players.
You have a point about the tools, but come on that problem goes away some time after you switch to metric and that way we (the rest of the world) don't need to lug around half a ton extra tools when we also need to maintain american equipment.
Luckily not much equiment is being manufacturered in the US, at least not much that get exported, so that problem isn't so large as it might be;)
Your second point is completely wrong, noone is going to stop making parts for your engine just because they are measured in inches.
The country I live in went metric rather late (around 1900) and there are still some places where parts are measured in inches because the parts have to fit the old gear.
Water pipes commonly come in 1/2, 3/4, 1 and 1-1/2 inch sizes, although I can't for the life of me figure out where they measured those sizes.
The length of those pipes are all metric though:)
New pipes that don't need to fit old pipes are always measured in mm, that includes copper and PEX tubing.
You seem to be under the impression that I'm in the US and that the guy at the lumber yard is somehow metrically challenged.
I'm in Denmark, nobody uses inches for anything other than a few legacy applications, like the names of a few popular dimensions of wood, 2x4, 4x4, 1x5 and so on, the funny thing is that it works like I described it.
The 4x4 was 100x100 mm after it got out of the sawmill (an inch is 25mm in this context), but if it was planed, then it will be about 6mm smaller on each side, but it's still called four-four-lumber.
That's exactly why I refuse to listen to salesmen at the lumberyard when try to talk to me in inches, because it's bloody useless.
Say I wanted a planed 25 x 125 mm plank, if I asked for a 1 by 5, then I'd get something like 19 x 119 mm because the measurement is what the wood *was* when it came out of the saw at the lumber mill.
I like mm, not just because it fits better with the rest of the world, but also because it forces people to talk about the goods I'll be getting rather than what it might have been like at some earlier time.
We manage to buy pints of beer quite nicely, eventhough noone alive in this country has ever used pints for anything other than to buy beer in english pubs.
Customary American Units are an abomination, it's a bloody mess and the only reason you can't see it is that you have been steeped in it since birth.
Everything is harder with CAU, except comparing new bits to old bits.
1) Force all business to use metric whenever anything is sold or advertized (this doesn't really cost anything). 2) Only teach metric in the schools. 3) Wait 20 years. 4) Make it illegal to use the old units for anything at all.
Somewhere along the line you'll get profit:)
Until you get to step #4 we (world - United States, Liberia and Myanmar) can make fun of your contortions and strange conversion factors that need to be applied to do even the simplest thing:)
Quick, tell me how many miles per gallon 40 rods per hogshead is, if you can do that without looking anything up then you get to keep the old system, otherwise you will need to convert.
Ah, yes, but a good craftsman doesn't blame the tool for a poor result, but that's probably because the good craftsman chooses good tools and refuses to work with poor tools.
Not knowing how to use a tool and choosing a poor tool are both faults of the craftsman.
I think that explains why so much php code is utter crap, the skilled developers stay far away from it, although some times some unlucky soul is forced to use php by his PHB and that some times leads to a working application.
This type of pump is water cooled, which is why it cannot be allowed to run dry and it's typically cooled by water well above 70 deg Celcius.
Having the pump outdoors is exceedingly stupid though.
The entire setup is dangerous and poorly thought out as others have pointed out, so killing a pump or getting electricuted ("a GFI might be good thing") are probably two of the cheaper problems he is going to encounter.
Now, had it been me I would have used a very light oil on the computer side of the heat exchanger (placed in a hole near the pool) as the oil prevents corrosion and it doesn't conduct electricity so a minor spill would not kill any electronics.
It would probably be a good idea to run the oil loop at a slight vacuum and to have a sensor to shut down the oil pump and the machines if the vacuum disappears for some reason, to keep the damage in case of a leak to a minimum.
I just don't get your cowboy electrics, it must be the low mains voltage or something, because around here it would be unthinkable to have a residential power without a GFI.
Well, I have a number of servers on static IPs that SORBS think are dynamic.
I have tried telling the idiots that they are wrong, but to no avail.
It's really a problem that people trust such a bunch of retards, because it's hard for the administrators of the mail servers to know if important mail is being blocked, very hard for users to know and even more impossible for users to smack some sense into the the head of the fool who runs their mail server.
What I have done in stead of using the static and poorly administered black lists is to use a number of short term, spamtrap driven blacklists, sbl-xbl.spamhaus.org which is somewhat static, but seems to be well run along with greylisting.
With greylisting most spammers never try again and even if they do there is a good chance that they will fall into a spamtrap and be stopped by the RBL the next time around.
I used to use SORBS (that was before I figured out they were fucking around), ORDB (which ended up taking almost no hits) and a few other lists and with the new setup I have gone from getting 70 or more spams pr. day to less than one.
Ditch SORBS, they suck because they list much more than just dynamic addresses and refuse to fix their mistakes.

Interlaced video sucks and needs to die, I'd much rather have 720p than 10800i.
Have you ever seen a video shot in 1080i on an lcd screen?
It looks like ass that has been though a wood chipper, because the two fields of interlacery belong to different times.
A movie image that has been converted to 1080i can be reconstructed into 1080p with half the frame rate and that's fine, but why not just dispense with the interlaced crap then?
Wouldn't it be much nicer to broardcast 1080p at 24 fps like real film and then have the screen frame double or triple the framerate if it needs to?
An LCD screen will have no problem being updated at 24fps, only a CRT screen will need to do some frame doubling.
I hate that the content providers feel that they need to change their content to fit the screen that I have, because they will almost always get it wrong (DLP, LCD and CRT are not the same) and force the player and screen to do crazy shit like deinterlacing and cropping (to get rid of letterboxing).

Are you trying to tell me that the bastion of Internet standards, Microsoft, cannot produce a mail server that understands temporary errors?
If you are right then people will need to stop using exchange for real Internet mail now rather than break the rest of the worlds email.

In the words of a googler: We buy crap.
I'm willing to bet that once the hardware is too crappy for Google, that it's completely useless for anyone remotely sane.
Look for completely broken hardware at recycling places.
Yes, some of us have HD CRT projectors as well:)

Guinness is a fine mainstream stout, nothing wrong with that.

C/C++ are primitive languages barely above the level of Assembler macros.
Java is a bit nicer than C++ but it just can't perform at the level of C (how many OS'es are written in Java?)
perl/ruby/python are closer to being good languages, but they still don't perform like a compiled language.
I don't know if D gives the features of Perl with the speed of C, but it's certainly a step in the right direction.
