Might I also recommend akismet which is quite good at filtering spam and is very simple to setup. Also, just disallow more than a couple links from anonymous comments.
That's true. I bought a 128 meg box for 2.25 from another provider. I run my primary postfix server on it, and prgmr runs a backup postfix server among other stuff.
Anyway, 6 months in my cheaper box is mysteriously reset, postfix config gone, but it's still accepting (and rejecting all) email because the default instance runs sendmail out of the box. Emailed support, they apologized and gave me a month. Still REALLY ANNOYING. PRGMR doesn't pull that kind of crap, so I'm happy to pay the extra for it.
this occurs with me periodically. It scares me in the same way someone hiding and going boo scares me. The first time you're really scared, after that it's just something that happens sometimes.
To answer your question, it doesn't sound like it's in my head. It sounds as if I were to play someone screaming or buzzing over some headphones.
Batteries die whether you use them or not. Modern laptop batteries don't really need any special care or cycling. I say just use and enjoy your laptop and stop worrying about the battery. When it dies, it dies, and you can go buy a new one at that time.
Open source and works wonderfully well. Also, easy to mod. I put in a Pinboard.in sharing link for all my articles, and you can do the same with just about any service in a few minutes with PHP.
