comment Is publishing your public IP address a security threat?
This. Posting your public IP on a message board might raise interest in trying to hack the computer or network behind it, but there's really no way to avoid someone else knowing about it (even if that person is the anonymous proxy gateway you route your traffic through).

comment How is “hacking” even possible if I “defend” properly?
"As the defender, you must win 100% of the time. A hacker only needs to win once." - This, x1000.

comment DDoS - Impossible to stop?
Short and sweet, but somewhat incorrect. Most DDoSs are the result of a botnet. Botnets, however massive, are a subset of the Internet, that attack by making sustained, rapid requests, often in a manner differing significantly from legitimate traffic (no legitimate user sends SYN after SYN without completing the handshake). More sophisticated attacks that turn legitimate users against a site (DNS hacking, malicious Slashdot-style linking) are harder to defend against, but also harder to pull off and control (as in Tom Leek's analogy; you set it up and hope for the worst).

comment DDoS - Impossible to stop?
@makerofthings - Your ISP is still trying to send all other traffic to you, and you still have to perform some cursory inspection of the packet to determine it's a rotten egg. It's a losing game; a coordinated DDoS attacker can add zombies more easily than you can reduce the time/effort needed to reject their packets.

comment Could once infected machine be ever trusted again?
Regarding the last two sentences - While I totally get the point, I'm not sure that's fair; the whole point of modern computer/OS design is that you don't have to know the bits and bytes at the hardware layer in order to write quality end-user software. Saying that anyone who doesn't know how to store a virus on a keyboard's EEPROM shouldn't write software is like saying that anyone who can't pick a deadbolt shouldn't be replacing the exterior door of a house. Two completely different skillsets are required, and while one person may possess both, one does not require the other.
