Chained-word passwords

Dave Farquhar security

Tom Gatermann asked me about a new password concept. How about, instead of 16 characters of gobbledygook, you chained together three unrelated words and separated them with garbage characters?

It would be easier to remember. But is it strong enough?

I think he’s just trying to get me to do math. But let’s look and see. Read more

Facebook’s IPO doesn’t have to be the end of Silicon Valley

Dave Farquhar Uncategorized , , ,

I saw a story on Slashdot this weekend writing Silicon Valley’s obituary at the hands of the Facebook IPO. The logic is that since social networking is an easier path to riches than traditional science, people will choose social networking.

In the short term, he may be right. But in the long term? The Facebook IPO looks more like Dotcom 2.0 to me. Read more

Replacing bad capacitors in failed electronics

Dave Farquhar Saving money , ,

If you’ve had a piece of electronic gear fail in the last few years, there’s a good chance it’s due to one or more bad capacitors inside. The problem most infamously reared its ugly head on motherboards produced just after the turn of the century, but that’s just a place where it’s highly visible. If you had a DTV converter box, a DVD player, or some other device fail in the same timeframe, it may have had the same problem.

If I had a failed motherboard, I’d probably just swap the motherboard unless it’s vintage or otherwise collectible. I’m more inclined to fix an LCD monitor or a DTV converter box. Read more

10 worst ways to make extra money

Dave Farquhar Saving money , ,

Wise Bread gives the 10 worst ways to make extra money. The scary thing is, I’ve actually looked into most of these, and tried some. And they’re mostly right. Most of them are just a waste of time. Here’s what’s wrong with them, and the caveats with the ones that are halfway useful, for a limited time.

The real benefits of having a CISSP

Another question from the big box o’ Google search queries: What are the real benefits of having a CISSP?

I don’t want to be flip, but here it is in two words: job security. Read more

Things I wish everyone knew about home Mac security

Dave Farquhar Macintosh, security , , , , , , , , ,

On Wednesday evening, I wrote about basic computer security from a Windows-centric perspective. I knew some people who needed help in a hurry, and given there was a 90% or so chance they were running Windows, I took that route.

Some of my buddies who use Macs passed it along. And much of what I said then does apply, but I’d like to clarify a few of those points.

Is the Windows firewall safe enough?

Dave Farquhar security , , , , ,

Is the Windows Firewall safe enough? I wish more people would ask that question rather than make assumptions.

I wish I had a nickel for every time I’ve heard an unsubstantiated statement like “Windows firewall is junk.” I went looking, and the best I could find was this, an editorial that said it doesn’t do enough to address outbound connections, particularly on a program-by-program basis.

OK, point taken. But “enough” is a moving target.

Things I wish everyone knew about home computer security

Dave Farquhar security , , , , , , , , , , , , ,

I’m a security professional by trade, with two certifications. I’m not responsible for defending your computer networks, but I want your networks to be secure. There’s a really simple reason for that. If your computer and your network is secure, then it isn’t attacking mine. Or anyone else’s.

Several fellow subscribers to a train-related interest group that I like got hacked recently, and have been sending out spam messages. They’ve received a lot of advice in the hours since. Some of it has been good, and some not as good. So I tried to think of some things that people could do in about 30 minutes to keep the crooks at bay.

Incidentally, the computer crooks won’t be going away. Computer crime happens because the criminals can make more money doing that than doing something legal. The only way to make it stop is to make it too hard, so that getting a real job becomes more profitable. You won’t solve that problem in 30 minutes, but if we all take that single step down that road, we’ll make the world that much safer. So, with that, let’s roll up our sleeves. Read more

3D printing hits $500

Dave Farquhar Uncategorized

The Solidoodle is the first fully assembled 3D printer to hit the magic $500 price point.

Nobody has reviewed one yet, and the device makes some significant compromises in order to get to that price point. Given that, I won’t be among the first to buy one. I’ll reserve that decision for a time when we know what it can and can’t do. But if we look at history, that $500 milestone is important.
