A million e-mail accounts. That's a lot. You're facing the potential of hundreds of thousands of users hitting a POP3 server once a minute, without taking into account the webmail and any IMAP use (with its associated socket inefficiencies). This means you need a lot of equipment and hacking skills.
So, to handle the load you need a lot of servers. For a million accounts, you might be looking at twenty medium specced Linux boxes. So log into the company's GoDaddy account or whatever and set up twenty MX records for each of the different machines. Now you're ready to do the real work.
Set up a basic POP3 and MTA on each machine. Doesn't really matter which. Sendmail is fine, but make sure to order a book so you can correct any config mistakes over the coming weeks. You also want to install SpamAssassin. Avoid the latest version for certain reasons. SpamAssassin 3 will do. Get this all running on each machine. Assign usernames and passwords to all users and create all the accounts on every single machine (more on this later). Tell all users that any who have problems can get in touch with you, otherwise they might get upset. Try to send this e-mail before the MX records propogate otherwise they won't get it for a while.
As the multiple MX records mean mail will be going to a random server, it is essential every user be on every machine. So how will people get all their mail rather than a twentieth of it? Easy, you set up a round robin DNS on mail.DOMAIN.com. This way whenever a user checks their mail, they'll randomly end up on a different mail server, therefore collecting more of their mail.
IMAP gets trickier in this situation, but I came up with a solution. Since no-one uses IMAP, you can dedicate one box to it. Set up all the accounts there and write a Perl script which logs into all the other boxes on POP3 for every account, then puts the messages into the folders on the IMAP server. Get this script to run (with crontab) every minute.
Webmail will need a similar script, but I leave that as an exercise for you as I've given you enough strategy already.
Most people follow a bell shaped curve for their ratings, with the 3-star rating being the most common.
I mean, where is this statistic coming from?
In my case the majority of rated songs are 5's, almost the same number of 4's, then some 3's, and hardly any 2's or 1's.. with perhaps 50% left unrated. I use iTunes at least several hours a day. Those of my friends who use iTunes seem to have a similar distribution.

Yeah, I mostly play emulated games myself! I shifted over to the Mac though, so that's about the limit of Mac gaming;-) Luckily I'm not "really" a gamer.
Still, with the crazy low prices of components now, I'm surprised you haven't splashed out:)
I generally post under another account, but this is what my laptop is logged in as, as it's an older machine. That sig was an old (a few years ago now) experiment to measure two things. One, the word mogorific had no entries in Google, so I could see how well Google tracked my posts. Secondly, I wanted to see whether Google would blindly link link text to a domain. Back then it did, now it does not.
Man, I've seen some shoddy economics in my time, but that guy has no idea what he's talking about.
If I must pay $6.25 or $7.25 an hour to whomever I hire, does it make sense for me to hire a worker whose skills enable him to produce only $4.00 worth of value per hour? Most employers would view doing so as a losing economic proposition.
Employers wouldn't pay someone who produces only $4.00 of value per hour anything. You generally expect an employee to, at the most difficult of times, have a value of 25% over their salary, but generally double or more. Someone producing $4 an hour in value is not even worth the paperwork.
People being hired at minimum wage are certainly of more value to employers than minimum wage. The minimum wage simply reinforces that low value workers should receive more of the pie than they were previously. I won't discuss whether this is a good idea or not, though, but I am traditionally an economic conservative.
You are confusing the two issues. What I said is that a licence is required if you receive any channel, even if you can't receive the BBC.
Let's say you point your dish at IntelSat or some Arab satellite.. you can't get the BBC, but you still have to have a licence. They confirm this by saying:
You may have been informed, in the past, that a television licence was not required if you received television program services from outside the United Kingdom. This was changed in the Communications Act 2003, and if you are using your TV to receive or record television programmes broadcast by satellite from outside the UK, you are now legally required to have a TV licence.
Being able to receive BBC channels is not a requirement, alas. This is a change from pre-2003.
Bzzt, totally wrong. The Broadcasting Act 2003 changed this. You must now pay the licence fee (tax) even if you only watch satellite broadcasts which originate from a different country.
You have to be kidding. Even if you have experience with all of those things (and I believe you do), you shouldn't list them all on a résumé! Seeing that list, as an employer, would make me think you're not a specialist.. and sadly generalists don't fare too well in the typical world of recruitment. This is further magnified by your work experience.. publishing, HR, and govt. project management. All good jobs, but there's got to be a better way to present it if you're aiming for a specialized job. I learned this the hard way.
A hobby? This is THE Carmack from ID Software. I can't believe the original poster thought that the game stuff was just a side thing. It's the other way round, the space stuff is his hobby and he's most famous for writing games like Doom and Duke Nukem.

If you ever get a chance to listen to a good FM tuner ...
And a good station. Most stations have tons of processing designed to make those cheap-o FM tuners you mention sound good. They also use tons of compression, ideal for today's pop music, but not so great for quality, given the potential dynamic range.
One of the only stations which has truly sounded amazing on FM, to me, is BBC Radio 3 in the UK, as it's an 'arts' channel, with almost no processing and no compression (you have to turn the volume up double just to get the same typical 'average volume').. but that's definitely not music you could listen to 16 hours a day.
FM sucks because it forces broadcasters to deal with the lowest commmon denominator. With digital, they can pump out a better signal for you to do with as you will.
Digital terrestrial radio in the UK has sucked, however, because stations seem to think that 112kbps MPEG 1 layer TWO is somehow passable. It's worse than FM! If you get digital satellite or TV-based terrestrial, however, you can get 192kbps pretty much across the board, which is very nice:-) Lots of discussion on this in alt.radio.digital..
A lot of big companies still use COBOL, and COBOL is over fifty years old, which means we can keep using X even if it's not being developed anymore. If something is worth using, then it must have a good solid base which can be used for many years to come. We don't need to worry at all for another fifty year or so, when we'll probably need a new system. Why panic now?
Many systems have lived beyond their original development schedules. Financial software written in COBOL, for example, which has caused no problems at all since it was developed, Windows 3.1 which is still more than good enough for most schools and small businesses and has no security flaws despite all thsi time, and the B programming language, which many an OS kernel is written in.
That's irrelevant, given the way it was worded. It was stated that God is the 'source of all creation'. Intellectual property is not 'created', it's merely a representation of the licenses held over tangibles.
If God were truly the source of all creation, then anything that is created, tangible or not, would belong to Him. The original poster responded above explaining the concept of leases, and other Islamic short circuits which I find quite confusing.
I've only seen that ad once, and it was in a cinema. I've never seen it come on TV, and I even told a few people about it, but I've never seen it come round, or heard back that it has ever been on TV. Clearly it got/gets very few slots, or hasn't been fully released yet (some humourous ad campaigns are run in cinemas first to gauge reaction).
If that were entirely true, no-one would get paid in Iran, since everything would be considered the 'product of God', since God is the source of all creation.
Your story sounds unlikely. The Athlon XP family was only just launched 2 years ago, and didn't hit 1.8GHz until the XP2200 some time later (unless you're talking about the XP1800, which isn't 1.8GHz). 3.5GB of DDR RAM would have set you back an extreme amount of money two years ago (it still does now), making your budget sound unlikely.
And why would you spend that sort of money on a system without redundancy? Two years ago it would have been cheaper to have built two 1GHz machines, hooked them via gigabit LAN, and put the database on one, leave everything else on the other. Then have them mirror each other's jobs in reserve, and then set up external DNS so you could switch over to just one if one blew up.
I'm not calling you a liar, but I just struggle to see how you could have built a machine with such a spec for under $4000 in late 2001/early 2002.
This exemption to political organizations could result in similar issues as to the protection that religions get. L Ron Hubbard created Scientology, as he was getting too much flak from the scientific community on his ideas about Dianetics (tm). Laws offered protection to religions, and so Scientology was born. Numerous other 'questionable' activities have been 'religionized' or 'charitized' because of this. So, what next? Could we have penis patch and viagra companies becoming political organizations?

That'd be cheaper than the US price though. The US price for the basic one comes out at £195, so it's only a £14 premium at the end of the day.
