For this exact type of thing, check out Dwolla. Paypal-style transactions (unique id is your email, but that's where the similarities end). It's run by a REAL bank (Veridian Credit Union, that's been around since 1934), and they do bank to bank transactions for 25 cents.

Disclaimer: I'm not in any way affiliated with Dwolla and don't gain anything by this post! Actually, as a business owner who accepts Dwolla payments, it would be nice to see this thing grow and become a standard thing people have to make it easier for everyone to pay each other, including me! :)

Definitely not a theoretical risk... as being in computer related work for the last 20 years I've seen a dozen machines fail due to power issues (lightning strikes mainly). I had a customer *using* a ups who had his motherboard, drive and mostly everything fry (the cdrom still worked) after a lightning hit. Despite having backups, he needed to recover the last day's work which forced him to send his drive out for full recovery for several thousand dollars.

I had a customer with an office of 20+ machines have half of them fail when lightning took out their main panel. The machines that survived were ones with UPSes.

Or, buy a box that already runs vyatta. The Ubiquiti EdgeRouter

http://www.ubnt.com/edgemax/ed...

At less than $100, with build in switching, embedded linux and apt-get support, you can't go wrong.

Oh, and it's quiet. (No fans)

And wait, there's more! Their $175 version the Edgemax Pro has 5 ports and 24/48v poe. (You'll need to buy a third party power brick for 48v poe, but it's worth it)

The way X11 does forwarding is very handy and useful, and I make use of it fairly often. But as usual, there's more than one proverbial way to skin the proverbial cat.

X11 forwarding is great for high speed and low latency connections such as a lan. Using it on anything else is asking for trouble, because if you lose your connection, you lose your app. Perhaps an improvement can be made to X11 forwarding in the new path forward (wayland) to make it more like screen where you can attach and detach to a running X11 app from a networked endpoint.

Remote desktop using RDP is superior to X11 forwarding for lossy connections because once the screen is loaded, very minimal draw/drag/etc communications are sent between the server and client for updates, X11 is far more data intensive for screen updates. And of course if you lose your connection (which I frequently do, trying to RDP from my cell phone), you'll get your apps back when you reconnect.

Having both X11 forwarding and RDP is a great choice, and I hope something similar to my aforementioned improvement makes it into the app.

FreeBSD has the one killer feature for me: ZFS. It's portable in a pinch and ensure a decent amount of data integrity.

In theory.

In practice, a normal RAID10/RAID1 array is more reliable ...

I went through the same thing. I waited until freebsd 8 to try zfs after watching some videos about how awesome it was. I had been running multi TB storage arrays on lvm + raid1 on linux for years and decided to try and switch to ZFS. The lack of an fsck really shows when you get data corruption issues while resizing a pool. ZFS also lacks the capability of downsizing a pool, so when the upsize fails half way, you're fairly fscked. The recovery tools are just immature compared to even things like ext3. Trying to recover from the failed ZFS upsize involved raw disk editing to change uuids to try and move back to using an old drive that had good data.

I got the ZFS array working enough to pull off the new data and move back to an lvm append + raid1 setup. I've had failed lvm moves and failed lvm upsizes but the recovery is so easy because all the metadata about the array (and plenty of automatic backups) are stored in plain conf files. Ah the beauty of simplicity.

And speaking of bleeding edge, I've been playing with btrfs for some non-critical stuff and I've been very impressed. Much moreso than with ZFS.

Not only the simultaneous connections (due to orthogonal signaling) but also due to its longer range and higher capacity in general. GSM being TDMA has a strict limit of 20 per tower and bandwidth usage is far less efficient.

Haha, what are you smoking? TDMA is a method of communication, just like HTTP is a communication method (albeit a higher layer), and has nothing to do with speed.

Versus my Chemistry class in Middle School...

Two weeks into the semester the teacher did something to amuse everyone by causing a reaction and capturing hydrogen in a beaker and then lighting it to get a little explosion. After that, it was more often than not: sit down, manually copy pages x-y from your text book, discuss last night's homework, learn 10 minutes of new things, then talk about this night's homework. No intelligent discussions about how this stuff is used in real world, just "learn this stuff from the book, it will be on your test, thanks for playing"
