As long as all software ever used is Microsoft software then the system is reasonably safe...once you allow other people and/or companies to develope software an MS system becomes insecure.
So hands up for everyone who wants to run only MS software.
I suspect they were looking at their bandwidth usage and found his usage was significantly higher than other people. This would then generate interest because they pay for bandwidth and their pricing formulas are built for occasional access. (The fact that they claim to sell full time access is another point.)
At that point they go to the house and spot the external antenna for the 802.11. Then they get one of their spectrum analyzers and determine that there is a lot of 802.11 activity going on.
Under this scenario there is no need for them to determine that the node is open, only that it exists and is accessible from outside the house.
What was illegal was the amplifier(s) on the 802.11 device(s).
At the risk of sounding like a company rep...I use DirectTV DSL (used to be Telocity). They have two packages:
The standard package is a 1.5M/128K line and 1 static IP.
The enhanced package is the same line but they provide the equivalent of a Linksys router for an extra $10/month.
Even with the standard package you are allowed to add your own router/firewall and put on as many computers as you want.
Their rules are basically:
The system is to be used for business purposes only occaisionally.
Don't do anything illegal
I run a VPN tunnel to work so I can get to home from work, a web server so my folks can see pictures of their grandkids, a mail server so I don't have to use DirectTV DSL's crappy email service, a db server, and a vpn server so my dad can get into my home network. The point is, all of this activity is allowed I don't have to hide it from my provider.
I can get cheaper DSL, I pay $10-$15 more than other people do for DHCP, PPPOE or PPTP connections, but I get a static IP address and an awesome TOS.
I have to agree with this one, with all the complaining about TOS and the like with the cable providers a good DSL provider is great. I use DirectTV DSL with their standard package (1 static IP). The only major problem was with the telco, the voice lines kept dropping off and that was Pacbell's equipment. (Actually it was kind of nice not to have the phone ringing...)
I run a web, mail and db server as well as a VPN tunnel to work. I am explicitly allowed to do this.
Sure I only have 1.54Mbps download (yes I get it) but that's plenty fast and the 128kbps limit on the upload rarely bothers me.
1. An unused cell phone is often in a spot where it will have to use more power to reach the tower than a phone in use 300 feet away.
2. A difference of 300 feet compared to miles is so significant that the difference in power if all other things are equal will be minimal.
3. A cell phone acting as a repeater will use more power than a cell phone acting as an client...it has to maintain two seperate connections that both require power. This is done by transmitting on two different freqs or by increasing the duty cycle, either option will require more power from the phone.
It's a neat concept but it would be practical so rarely that it's really a waste of design time.
I had a very similar situation, but I didn't care for the work so I moved. My new employer had actually given me a low offer (for the area) and shortly after moving I got a significant raise.
Because the jobs were in different areas of the state the counter offer was actually worth quite a bit more but by moving companies I got to move from a support type job to design.
I have three machines at home and several at work. It's really nice to have access to both networks from either place.
Stuff at home that should never be down goes on the Linux Samba server, my wife's pictures go on the dual boot Linux/Win98 workstation. My son's games go on the Win2K machine.
At work I put all my documents on the Win2K server except for stuff I'm working on in solid modelling, 100Mb isn't fast enough then.
I use VPND to join the two networks, so Samba, ftp, etc all work over the VPN. VPND is nice because it's a router-to-router VPN and I don't have to worry about configuring client computers to use it.
For backups, at work I don't have to worry, IS backs up my documents if I put them on the server. At home I just dump my data to a CD.
I don't know what computer you have, but in all of my computers the AC stops at the power supply and everything else inside the case runs off DC. This means that as long as the power supply is happy with the square wave the entire computer is happy with it. Most monitors will function just fine on a square wave as well.
I have seen a UPS power supply for sale somewhere, just can't remember the link right now. That concept has the problem of not being able to power the monitor--not much of a problem for a server, but for a workstation it's somewhat critical to be able to see what you're doing.
First, you need to consider the possibilitiy of moving the mailbox. To a different computer, or a different platform. This means it must be easy to access in any environment, and the tools must be portable.
This doesn't completely rule out a database solution (like mySQL), but it certainly makes it less-than-ideal.
Actually, moving a database from one system to another can be very easy.
I use IMAP whenever I can, and when I can't I use fetchmail to pull my mail to an IMAP server I own. IMAP is really nice but the Linux implementations I've seen have a great deal of overhead per user. From what I understand a lot of that overhead is message accessing, most server programs don't do it very well.
We have methods for accessing large amounts of data and pulling out the relevant portions: a data base. A well written server (ending up as a db client) could be made to work with most database servers. If the data base structure is properly designed the data would be easily transportable from one system to another as well.
Well, from a historical point of view HP was a test and measurement company. They expanded into the clone market, but what they were respected for was still the test equipment.
The real HP became Agilent a couple years ago. I heard that when preparing for the split HP determined that the PC portion of the business would not survive a name change (which means all they had to offer in competition was name recognition).
HP is alive and well and out of reach of Carly, it's just known as Agilent now.
(And no I don't work for HP, I work for a competitor.)
I have a friend who lives away from the power grid in Kenya. He uses a solar panel on the roof and lights the house with LEDs. He says it works good, but it definately does not light up the entire house.
You need to control the current into the LED. This can be accomplished with a trimmer POT but that again wastes power. An adjustable switching power supply (in miniture of course) will efficiently control the current into the LED minimizing the power wasted while providing very good control over the dim function.

My hand is most definately down.

I play one two servers that both run csguard and I always have stable games.

A marine style battery may have better performance for a UPS, they're usually designed for slower discharge rates.

Just my $0.02 ($0.03 Canadian)
Waterproof would be good. I've lost one remote and nearly lost a second when my son decided to see what they would do when dunked in his juice.
