How easily can someone hack my home computer and steal personal information?

On Monday, March 13 at approximately 10:30 AM CST, I will be appearing on KFUO Radio’s Faith and Family program to discuss home computer security with host Andy Bates. Here’s the scariest question he’s planning to ask: How easily can someone hack my home computer and steal personal information?

Someone asked me that question at work once, except it was about a work computer. I whipped out a copy of a book about Metasploit, flipped to page 137, and started reading. My point was that I could teach this guy how. He didn’t take it well, so I don’t recommend doing that.

My point that I could teach this guy how to do it still stands, though. And I think I could teach Andy how too.

How to disassemble a Lionel 1001, 1060 or 8902 locomotive

Disassembling a Lionel 1001, 1060, 8902 or 8302 locomotive isn’t too difficult. The biggest problem is knowing where the three screws are that you have to remove.

These particular locomotives weren’t really designed to be repaired, but there’s some basic work you can do on them with household tools. The 8902 and 8302 locomotives can be cheap sources of a motor for other projects.

Save money on appliances

Save money on appliances

If you want to know how to save money on appliances, I have some unconventional advice: Buy used. Yes, really. Here’s how to buy used (or refurbished) appliances and save big money without getting ripped off.

I’ve had a number of friends get hit recently with appliance breakdowns they couldn’t afford, and since I’m a landlord, I’ve probably bought a lifetime’s worth of appliances in the last seven years. A dead appliance doesn’t have to turn into a financial catastrophe.

Recommended DD-WRT settings

I’ve been asked a few times now for my recommended DD-WRT settings, or at least my good-enough settings. I think that’s a great idea, so I’ll walk through how I configure a DD-WRT router. Follow these steps and I can almost guarantee you’ll have the most secure network on your block.

For the purposes of this tutorial, I am going to assume you are configuring DD-WRT as your primary router.

How to disassemble a Marx 490 locomotive

How to disassemble a Marx 490 locomotive

Disassembling a Marx 490 locomotive isn’t too difficult, but it’s very different from other Marx locomotives.

Once you take one apart, though, you’ll see why it was designed how it was. It was Marx’s lowest-cost locomotive, and it could be assembled without tools, so the labor costs were minimal.

For that matter you only need one tool to take it apart, and since there’s so little in it that can break–not even a headlight–you can find anything you would need to service it at the nearest hardware store or auto parts store.

Testing electric train track

Testing electric train track

I have a method of testing electric train track from Lionel, American Flyer, Marx or any other brand. The key is to test it one piece at a time, so you know any problem you found is isolated to a single piece of track.

Here are a couple of different ways to test, depending on what tools you have available.
