What's happening with Truecrypt?

Recently I noticed a lot of controversy about whether Truecrypt is secure or not. It looks like their webpage is raising concerns about it, even to the point of suggesting that people migrate their data away from it. Arstechnica and others are following the story. What's going on? Might this be a hoax? Are truecrypt encrypted flashdrives not safe? If not, what level of security do they provide, if any? What would be a good alternative if we are to migrate away as quickly as possible?

Help me understand what a proper business IT system looks like.

I've only worked in a small business (15-20 employees) since I got out of school, and I've handled the technological necessities since I started because nobody else could. I've handled things on an as-needed basis: troubleshooting problems, setting up new computers, maintaining an iron grip on software installations, setting up the network and administering simple network devices, etc. However, I'm completely self-taught, and I have no idea if my hacked-together system looks anything like a properly-implemented corporate IT system. So I want to know what one looks like. Specifically, I'd like to know if there are any resources I can check out on my own that paint the picture of what I should be trying to achieve. NOTE: I'm NOT averse to hiring an outside IT firm or consultant to help with specification and implementation. However, I don't want to be at the mercy of a firm's "knowledge" and my own ignorance; you can waste a lot of money that way, regardless of scenario. [more inside]

Looking for a community/forum where I can learn more about networking, code, security, and OS-independent CS topics

I'm looking for a forum where I can ask questions about networking, security, coding, operating systems, web design, etc. There are many of these out there, but I'd like to find a single community which covers all these topics more or less equally (so it isn't a Linux forum with a small section on BSD, or a coding forum with a small section on networking). I'd like it to be the sort of forum where users stay around for several years as they learn and contribute at different levels, with high literacy and education-to-spam levels. Could I have your recommendations please?

Setting up a password repository

Let's say I wanted to create a simple web app to store my various usernames and passwords. The app and database would be hosted externally (by Dreamhost). I would use a secure connection for any HTTP stuff going back and forth, and I would encrypt all of the passwords before going into the db, and I can only extract and decrypt a password after entering a pass phrase that exists only in my brain. What would it take for someone else to get at my passwords? [more inside]

Reviews of cheap SSL cert vendors?

I'd like a signed ssl certificate, as signing it myself leads to warnings from both Internet Explorer and Safari.
Verisign signs 128 bit at $895, which seems ridiculous to me.
Does anyone have positive experience with other trust vendors?
