“Will baseball cards ever be valuable again?” someone asked me recently. The answer is that it depends. Not all cards were valuable in the first place.
Part of the problem is there was a time when 90% of boys collected cards. Now they don’t. Prices dropped due to simple supply and demand.

Once people finish asking me how hard CISSP is, they often follow up with another question: Is CISSP worth it? As long as you have something to back it up with, I think the answer is a resounding yes.

Yesterday, half the Internet was broken. I knew something was wrong when I couldn’t get into Salesforce to check on a support ticket for my biggest customer. Another member of my team sent us a warning that a big DDoS attack was happening, and not to count on being able to issue very many quotes today. So what, exactly, is a DDoS attack and how do DDoS attacks work?
I suppose there’s another question to ask too: What can you do to avoid being part of the problem? We’ll save that for the end.

What happened to Packard Bell? It ceased operations in the United States in 2000, after a 14-year reign of terror on the consumer market.
But there’s more to the story than that. The Packard Bell story is a brilliant piece of marketing.

Purists prefer CRT monitors for a more authentic experience, but if you don’t mind an LCD, here’s a good LCD monitor for retro computing. Look for a Dell 2001fp manufactured in June 2005 or before. For bonus points, try to find one with a soundbar.
With any luck, you should be able to find one for under $60. Sometimes well under $60.

If you are wondering about cordless phone frequencies, there are seven bands that have been in use since the 1980s. You can still buy phones for four of those frequencies.
There are two reasons to be concerned about a cordless phone’s frequency. The first is interference. Some phones interfere with other devices, such as wi-fi. The other reason is security.

People frequently wire a ceiling fan with a light to two light switches. That way they can control the fan with one switch and the light with the other. But what if have to wire a ceiling fan with light to one switch? You can do it. You just have to know what to do with the fan’s red or blue wire.
First, remove the light fixture in the room. Make sure the box is rated for a ceiling fan. If it isn’t, hardware and home improvement stores sell boxes suitable for ceiling fans. Buy and install one. Safety first. If there’s anything odd about the old fixture’s wiring, use tape to mark what wires go where.
Mount the fan bracket according to the instructions that came with your fan. Then slide the fan into the bracket to get it ready for wiring.
Inside the electrical box, you’ll find either a single white wire or, more likely, a bundle of white wires. Those are the neutral, or common, wires. The ceiling fan may have one or two white wires. Connect those to the white wire(s) in your box.
Use the wire nuts that came with your fan, or use new wire nuts of the appropriate size. Wire nuts rarely go bad, but guess what? It happened to me, and it turned a 30-minute project into a two-hour one. Don’t make your project any harder on yourself than you need to.
Now for the trick. The ceiling fan will have a black wire and another non-white wire. That second wire is usually blue or red. That’s usually the hot wire for the light. Twist those two wires together, then connect them to the black or red wire that came out of your electrical box. Use whichever wire the old light fixture was connected to.
Finish mounting the cover and whatever else the fan’s instructions tell you to do.
That’s how you wire a ceiling fan with light to one switch. Now when you turn on your light switch, the fan will have power. To turn the fan and lights off separately, use the pull chains on the fan.
If your ceiling light fixture doesn’t work, let’s talk about one I worked on last weekend. It wasn’t my first time doing that. I ended up replacing the fixture, but then I fixed the broken fixture afterward.
