comment Why do ISPs change your IP address?
@BillP3rd: Having a dynamic IP does preclude hosting a professional-looking web server. when the IP changes, there is inevitably a short time when the site is unreachable--even with really short DNS TTLs--which are bad netizinship. It's also a security concern--especially for email (as I mentioned above). That doesn't mean it can't be done, but it does mean that any serious business won't do it (especially now days when you can get web hosting, or even a full VM for under US$10/month).

comment Why do ISPs change your IP address?
@agz: Now days, not much. In the days of dialup modem pools: 1) Buying extra IPs (probably 100x more than were actually being used), 2) equipment that could assign static IPs across different physical devices (dialup static IPs often had dedicated phone numbers, separate from the dynamic IP pools and sometimes a single phone number per static-IP customer).

comment Why do ISPs change your IP address?
@AndréParamés: I know I would be much more inclined to abuse my home service if I had a static IP. And I have many friends who feel the same. For certain things, a dynamic IP is not a reasonable solution. The two most obvious cases are 1) It looks very unprofessional if it appears in your URL (or a redirector). 2) It makes for an incredibily insecure mail server. These are enough to drive many people away from hosting web sites or email on a dynamic IP.

@BillMichell: Static dial-up accounts certainly existed. They were rare--and especially rare if you didn't pay for them!

comment Linux: Prevent iPod Touch from charging while computer is running off battery
The OS can detect when a system is running on battery power. The OS can disable certain USB ports. There's no reason the OS couldn't tie these two together.

comment Windows 7 Laptop - Truecrypt - Ubuntu?
The TrueCrypt docs say this plain as day, too: Encrypted partitions cannot be resized except partitions on an entirely encrypted system drive that are resized while the encrypted operating system is running.

You want to move it, or you want to copy it?
