Kevin Mitnick security awareness training – can you trust him?

A former classmate told me his employer is making him take Kevin Mitnick’s security awareness training course. “Is he really the world’s most famous hacker?” he asked me. “And if he is, why should I trust a word he says?”

Those are excellent questions. I happen to have reviewed all of Kevin Mitnick’s various courses for a previous employer, so I’m familiar with them. And I had to take Kevin Mitnick Security Awareness Training this year myself. I don’t agree with the life decisions Kevin Mitnick made that landed him in prison, of course. But overall, I had only very minor objections to his training. Here’s why.

Foldingathome – how little is too little?

Foldingathome – how little is too little?

Thanks to an influx of volunteers donating computer power to support COVID-19 research, the Folding@home project is now, in effect, the world’s most powerful supercomputer. But how much computer power is necessary to make a difference? After comparing notes with a couple of others, I think I have some answers.

Why no Windows 9? The surprising reason

Why no Windows 9? The surprising reason

After the hugely popular Windows 7, Microsoft followed up with the terrible Windows 8, and the only slightly less terrible Windows 8.1. And then they came out with Windows 10, which, while not as beloved as Windows 7, certainly was better than 8. But they skipped 9. Why no Windows 9?

Believe it or not, the reason Microsoft skipped Windows 9 has nothing to do with Windows 7 or Windows 8. The reason is a decades-old shortcut that was beyond Microsoft’s control.

Foldingathome with the Nvidia Geforce 210

Foldingathome with the Nvidia Geforce 210

I installed the Folding@home client on every computer in the house with something newer than a Pentium 4 in it. But GPU power is much better than CPU power. Even my lowly Nvidia Geforce 210. Here’s how I fixed an opencl.dll not found error, though I never was able to get much use from Foldingathome with the Nvidia Geforce 210.

Both Nvidia drivers and the Foldingathome client are finicky. When in doubt, uninstalling and reinstalling can work wonders. But while I was able to get the client to recognize my Geforce 210, I was never able to get it to fold.

What to do if you’ve been laid off

Being laid off isn’t something that happens to everyone. But it happens to more than you would think. It’s about being in the wrong place at the wrong time. That’s the key. Remember it’s not a failing on you. Here’s what to do if you’ve been laid off.

The keys to surviving a layoff is to burn as few bridges as possible, use the resources available to you, and try to land on your feet somewhere else. Here are some tips for doing that.

Is gigabit Internet worth it?

Is gigabit Internet worth it? I want gigabit Internet. I wanted it for a really long time before I was able to get it. And not everyone can. Here’s why I want gigabit Internet and how I can justify it. If you can get it, it’s worth considering. Here’s why it might make sense for you.

If you’re working from home and have a modern enough home network, gigabit Internet can make a lot of sense. But a lot of home networks aren’t up for it, so you may be wasting money.

Is it cheaper to build a PC?

Is it cheaper to build a PC?

Years ago, I was having lunch with a friend. “You probably don’t save much money by building a PC. I know when I build a mountain bike, I end up spending more.” His logic makes sense. But it’s worth exploring. Is it cheaper to build a PC?

What to do if you think you’ll be laid off

Sometimes we can see the writing on the wall. Maybe it’s because times are tough. Maybe it’s political. Often it’s a combination of both. And whether you think there’s anything that can change it or not, the way ahead is much the same. Here’s what to do if you think you’ll be laid off.

The Boy Scout motto applies here: be prepared. The sooner you can get your affairs in order, the easier it will be to weather the layoff, or avoid it entirely.

Soldering for model railroaders

Soldering for model railroaders

I saw some questions come up on a model railroading forum about soldering, and I guess there’s a lot of confusing information out there about it. I’ve been soldering for 30 years, so hopefully I can clear up the common questions about soldering for model railroaders.

The main reason you find conflicting information about soldering is the application. If you’re soldering wires to the track, the advice for soldering sheet metal together to scratchbuild cars will be very different.
