Frequently I have a problem with self-assemble furniture not holding together as well as I would like. The bolts back out over time the legs in our kitchen chairs get wobbly. Or a bolt from an office chair falls out completely and something that used to work stops working. If I don’t notice the mystery bolt on the floor and the malfunction on the same day, I get other problems.
The last time I got a wobbly chair, I had an idea. I wrapped the threads with PTFE tape. (Sometimes incorrectly called Teflon® tape. It’s the same chemical, but Dupont doesn’t make thread-sealing tape anymore.)
Normally you use thread-sealing tape on plumbing by wrapping the threads of pipes before assembling the parts. The tape makes the threads watertight and also helps you tighten them tighter.
In this application, I don’t need the threads to be watertight but I need to really cinch the bolts down, and the addition of a bit more material around the threads will, I hope, make the fit less sloppy and less prone to backing out.
It will also keep them from seizing, should you ever need to disassemble for any reason. You can use a thread locker, but this was Sunday night and the stores were closed and I didn’t have any. I had PTFE tape on hand, and it’s a lot cheaper.
After upgrading to Windows 10, when I unhibernated my laptop the next morning, my wifi connection didn’t work. Forgetting the network and reconnecting didn’t help–I’d get the message that Windows 10 can’t connect to this network.
The problem seemed to be in the power management.

So the UK voted to leave the EU, key political figures resigned, North Ireland and Scotland might want to leave the UK, and the stock market went into a free fall. What does it all mean? I don’t know, and nobody does. But don’t panic and close your 401(K) or move all the money into bonds.
I’ve seen this before.

“Daniel” from “Microsoft” called me the other day. The number looked halfway legit so I picked up. He out and out claimed to be from Microsoft and said he was getting alerts from my computer. His voice sounded familiar–I think I’d talked to him before.
“Which computer?” I asked.
“Your Microsoft computer,” he said.

I’ve talked before about replacing a power cord on a transformer, but for whatever reason, I forgot to mention a cheap source of replacement power cords that also provide a safety improvement.
Use a 3-prong computer power cord.

It seems like about once a month an aspiring coworker asks me how to get enough CISSP work experience. I think this shows a misunderstanding of the requirement, so I’m going to try to clear it up.
You don’t have to get your five years of work experience in one big lump. And that’s a good thing, because that would be hard to do. Sometimes you can get a security job without a cert and work your way toward it, but a lot of employers want you to come in with the certification already.
But that’s OK. As long as you’re doing something more than selling computers at retail, odds are you have some security experience that can count toward the requirement.

A frequent question I see is why the Lionel bulbs in any given accessory burn out quickly. I can sum up both the problem and the solution in a single word: voltage.
When you have too much voltage, bulbs burn out quickly–sometimes in minutes. When you have too little voltage, the bulbs will last decades.
