You just need your own domain... where you can recieve email for any address at that domain.
Every time I give out an email address to someone new I give them a unique email address. Every time I put my email into a web form for some company they get it in the following format:
companyname@mydomain.com
friends can get silly things like: spankie@mydomain.com or whatever.....
other examples: planetside@myname.com jobs@myname.com bioinformatics@myname.com
Then, if I begin recieving spam on one of the addresses I know exactly who it is coming from or who at least is responsible for giving out my email address. I can also go in and specifically turn off the offending email address, or better yet have each mail recieved fire off a "custom" error message or some script I have setup.
I've been using this method for a year and believe it or not I don't recieve more than 1 spam mail a week and never recieve it more than once on any given address. What is wonderful is that I have no fear or worry about giving out email addresses any more.
Why rock the boat in this economy? You could be fired just because you pissed someone off. It's not worth the risk. Be happy you're working!
I know it really bothers you, but not as much as missing those paychecks will.
If you really need to, create one simple, nicely worded email outlining your concerns, and send it to the manager in charge. Keep a copy for youself. If in the future something does happen you can say, "see, I tried to warn you but you didn't listen. Here are my ideas for preventing it in the future..."

You can make a High Availability cluster out of most any software if you have some kind of shared storage.
People have used firewire drives connected to two different computers to accomplish this cheaply. Oracle is giving away a cluster filesystem (so they can sell RAC on linux) there is OpenGFS as well for filesystem usage.
Just write some basic monitoring scripts that will bring up your postgress database on the second server should the first one fail. Just make sure those scripts completely take down the old database on the first server in the case of a partial failure. Having two databases try to open the same data would be a really bad thing.
These are mainly geared for Oracle/RAC, all you need is the firewire shared storage and cluster filesystem. You're on your own to write the monitoring and failover scripts.
Hope this helps.

We are implementing a 3 tier high availability cluster using weblogic as the application layer. We have them clustered though a weblogic provided apache module on our load balanced web layer. It also survives the failover of the database layer as well. These things do still need consideration in the code you write (mainly the part about reconnecting after a database failover). Weblogic seems to handle the redundancy and load balancing fine if you let it maintain it's persistance by storing it's que and object data in the database layer.

It would take a remarkable amount of energy to move a heavy payload off of the moon and back to earth. That's assuming you can write off the engineering problem of how to safely bring down multiple tons of cargo intact. Remember that bringing down 7 people intact isn't at all guaranteed.
Think about it, you're not going to be harvesting fossil fuels up there. How much sunlight would you have to collect and store to provide enough energy to push a significant (100 Ton?) Mass out of the Moon's gravity well. Then, how are you going to slow it down enough to make a safe landing on earth? I suppose atmospheric braking could make for some pretty night skies over some parts of the world....
What are you going to use for cargo containers? How are you going to get them to the moon? (more fuel needed). Can we mass produce our cargo containers on the moon from raw materials? What about the energy just for construction and mining?
Solar arrays would have to be kilometers in size and even then they're not going to get any sunlight for a couple of weeks out of every month
It's a beautiful idea, but the reason we have so much energy down here is because of binding of the sun's energy by life, and in some part due to hydro-electric sources, again a function of solar energy. Even if we move to hydrogen based power you still aren't going to find much easily obtained hydrogen up there, or the products you need to react it with to make electricity.
Even fusion or normal nuclear power has problems because you need water to turn turbines and carry heat away.
I hate to say it but it all comes back to the same old problem we've always had. Where do we get the energy, and how do we harness it?

I propose a cash only, recordless DSL ISP. In our customer agreement we specifically state that people may pay by cash, or money order, and even if they do pay with credit cards, no records will be kept, beyond, payment received for modem #12345. No customer names are ever to be kept. Why do I care what your name is, all that matters to me is that you pay your bill, all that matters to you is that your DSL modem works.
For obvious reasons, no outgoing port 25 traffic allowed, otherwise this could be spammer heaven.
Customers would have to submit payment along with the uniq number identifying thier DSL modem. That keeps the modem on for another month. Once the transaction is verified, no records are retained, and we never link IP address to DSL modem.
Maybe we implement a daily rotating DHCPd IP scheme for good measure.
Supeona my business records? sure, here's 100000 cash receipt stubs with no names, have a ball.
I just did this at home. FYI a Radeon 9700 (non pro) sells for about $225 on pricewatch. Once the bios is reflashed that card can be clocked up to the exact same memory and core speed as the Radeon 9700 Pro. I've been gaming on it for weeks and it's rock solid stable.
It's very easy to turn your $225 card into a $380 card, and you don't have to solder anything.
As always YMMV
First of all a repeater typically listens on one frequency and broadcasts on another. Your radio hardware needs to support the feature and your cell phone doesn't. Second. The FCC has extra special laws covering the cellular range of frequencies and screwing around or even owning the equipment to mess around will land you a nice felony conviction.
Solutions for sharing a disk amongst servers usually entail a SAN or fiber connection to the disks, and some really expensive software (read veritas volume manager and veritas cluster FS) to handle it all.
In the linux world take a look at GFS.

The hardware they use to make it work will probably support what you're trying to do. Your typical off the shelf (At Frys) SCSI controller won't do the trick.
For what you're trying to do I highly recommend you work out some kind of sync between two networked machines with separate storage. If you're running a database it gets really fun. HINT for MySQL, script the replay of the SQL "update" log on the hot standby machine.
Good luck. My company just spent 150k+ on a sun/veritas solution to do exactly this. Our storage is all SAN.
Data center temperatures are maintained for the servers. Your needs are not a factor. Wear a coat. I've snuggled up to disk arrays for the warmth many time while doing long stints in our DC.

No pirated code is distributed with the latest XBox chips, as they are typically shipped with NO bios on them. It has been true in the past that some chips did contain copyrighted code and Lik Sang sold them. This is probably why they were able to shut them down.

How to Test Your T1?
·
· Score: 2, Informative
All bandwidth providers oversell thier available capacity. Almost no one (legitimate) uses all of thier available bandwidth all the time, so usually everything runs together fine. They have to do this to comepete with everyone else. A T1 isn't really a big connection any more and you're probably not going to be an account they bend over backwards for.
If you really want to be on a network that isn't oversold, you're going to pay 5 times as much.
Worry about response (ping, number of hops in traceroute, etc) times to AT&T @Home customers and DSL customers. At the t1 level if those response times are good, you are doing great.
When you move into a DS3 and up connections, the whole sales game changes again.
Being a teacher now is a thankless, low paying job. Both of my parents are teachers and I grew up in that "community".

I currently have 2 ferrets. My lifetime total for ferrets is 5.
My first advice is that if you're even a little bit wary of a ferret as a pet then DON"T get one. I personally know the owner of a ferret shelter that's just full of good animals they weren't prepared for.
First off and I hope this is all you need to change your mind. Ferrets are not really potty or litter box trainable. Yep, for thier entire lives you'll be cleaning up thier shit. Deal with it.
They only live about 6 years or so AND they are very prone to health problems. You'll love them as much or more than a cat or dog and loose them on 1/3 the time, usually to an accident or very expensive health condition. You MUST search out a good ferret vet in your area, don't use any old vet, they won't have a clue. This I know from painful experience.
They're perpetual 1+1/2 year olds. Imagine a mobile crawling baby that can climb. Hell bent on dumping any trash can, glass of cool-aid, papers, anything. A ferret can get into your girlfriends purse and scatter the contents over a 10^2 foot area in 2 minutes. And they'll probably hide thier favorite stuff where you can't find it. They are trouble, you have to watch out for them like children. Ferret proofing your home is the first step before they even get home.
The up side is that they're very happy in a large cage and spend all but about 2-3 hours a day in thier cage sleeping. So they're out of your hair most of the time and you can be prepared for "ferret time".
Pet store ferrets are HORRIBLE. DO NOT EVER BUY A FERRET FROM A PET STORE! Look I lost 2 ferrets primarily due to MASSIVE (read ~$1000-$3000 in vet bills) mainly due to the poor breeding and genetics of the Marshal Farms ferret farm. My latest pair I have from an excellent breeder and they simply LOOK much healthier, and I haven't had a single problem with them yet.
Oh yeah, you DO realize of course that ferrets stink, yes? As in, ferrets are cousins of Skunks and have a similar scent gland and musky odor. Even when descented thier natural "musk" is still in strong effect. My current 2 ferts are not descented and there is no difference in oder from the ones before, that were. Trust me, they stink. Go find a ferret and press your nose up against one and inhale deeply, didn't like it? move along.....
They're a handful, most of the time I tell people to please don't get one. I firmly believe most people won't like them in the long run even if they think they're cute now. They're stubborn, intelligent, tenacious as hell. Unless you're the kind of person who would enjoy babysitting 2 toddlers every night for years don't even think about it. Ferrets and kids are a NO-NO. ferrets are FRAGILE. and you can easily break thier backs if you're not careful. A child will usually hurt a ferret by not understanding this.
So all I'm saying is don't get one, please. If you think you really want one, spend some time around some first. They are nothing like a cat, dog or (grrrr... ) rat. There's no comparison.
You can learn most of what you need to about computer security by just installing RedHat, leaving it default, and putting it up on your DSL account.
Now, count the hours/days until you're compromised. Watch how they did it so easily, learn how to stop it next time. I couldn't think of a better way to start...
Around here (NW America) small computer shops always have the best prices. They compete with other local shops and it pretty much pushes thier prices down to about as low as you can get them. You can get most any component you'll need and often they'll assemble it all for you for free, if you want them to. I've buit several computers this way and had nothing but good experiences. Of course there's no tech support number to call..... but if you need that you shouldn't be building your own PC. Great prices, local availability, and you're helping out the little guy.
Me and my Ex spent hours beating the crap out of each other in MK4. PC version. We sat shoulder to shoulder sharing the same keyboard. And I have to be honest, sometimes she totally kicked my ass. Anyway, she got into the competitive fast paced nature of it and we had a lot of fun doing it together.
