Sometimes wire insulation gets damaged. The wire will still work, but exposed metal increases the risk of short circuit, electrical shock, or even fire. When you come across damaged insulation, you really need to fix it. Here’s how to repair wire insulation.
Occasionally someone asks me to recommend an HO scale holiday village or HO scale Christmas village. The big-name villages are too big for HO scale trains, generally speaking, so I understand. There’s no big-name HO scale holiday village but there is a very affordable one.
I recommend Cobblestone Corners, available at Dollar Tree. Old stock is easy to find on Ebay as well.
Is fast food considered retail? Only if you spin it. If you’re asking the question, that’s probably what you need to do. Here’s how to do just that if you’re looking for a change.
“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.

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.

CISSP difficulty is one of the most frequent questions I get once someone finds out I have it. “How hard is CISSP?” or “Could you pass CISSP again?” are two questions I get a lot.
They’re fair questions, and the answer is, it depends. But I can help you figure out the answer for yourself.
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.
