The best Pfsense hardware is rather subjective. I think the ideal Pfsense box should deliver solid performance while being affordable.

How safe is my computer from hackers?

Dave Farquhar security , , , , ,

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. One of the questions he’s planning to ask: How can I know how secure my home computer is? Or, to put his question another way, how safe is my computer from hackers?

I’m going to use this space to elaborate ahead of time on some of the things we are going to talk about. We could talk for an hour on any of the questions he’s going to ask, and he gave me three questions and 25 minutes. This is my workaround.

This, fortunately, may be the easiest question to answer and the easiest step to implement.

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.

Wire a Lionel ZW transformer

When it comes time to wire a Lionel ZW transformer, there’s more to think about than just which posts to use. The size of the wires also matters. If you derail a train 12 amps of power can run through the wire for 10-15 seconds before the circuit breaker kicks in. You don’t want the insulation to melt and catch fire.

Proper wiring for the ZW transformer is a bit of a safety issue.

Dave Farquhar Windows , , , ,

Here’s a good question. Should you migrate Windows 7 to SSD or install fresh? And what about Windows 10? This is likely to be controversial and everyone has an opinion. I’ll weigh the pros and cons of each, as a guy who knows  a little about optimizing Windows, and who has been using SSDs since 2009.

Is this vinyl tile asbestos? How to check.

If you’re working on a house built before 1978, and you’re renovating floors, you need to pay attention to the tile. Asbestos tile was very common before 1978, so you’re not being paranoid if you ask a question like, “Is this vinyl tile asbestos?”

While it’s impossible to answer the question for certain, there are guidelines to follow.

Commodore 64 vs Amiga

Commodore 64 vs Amiga

Looking at the Commodore 64 vs Amiga seems a little odd, at least to me. After all, the machines were never intended to be rivals. The Amiga was supposed to succeed the 64. Commodore bought Amiga because they couldn’t make a 64 successor on their own, so they intended for the Amiga to replace it. It didn’t fully succeed, and maybe that’s why the comparison is still interesting.

Looking back, the machines may seem similar today. But in 1985 they sure didn’t.
