Dave Farquhar security

When you’re hunting through job postings, sometimes you may see Security+ as a requirement. Sometimes you might see Security+ce instead. Theoretically, I’m out of luck if they really want Security+ce. Let’s talk about Security+ vs Security+ce and whether the difference means anything for you.

Security+ vs Security+ce really comes down to when you took the exam. If you took the exam after 2010, and certainly after 2011, you have both. If, like me, you took the exam before 2010 and didn’t convert it, you just have Security+. And some jobs require ce.

Erector sets frequently are missing screws, or they have screws but they’ve suffered the ravages of time.

What to look for in a Commodore 64

If you’re into retro computing, the Commodore 64 is hard to escape. It was the most popular computer model of all time, so it was everywhere in the 1980s. But the machine does have its quirks, which can be either endearing or maddening. Here’s what to look for in a Commodore 64.

Certain models and eras of Commodore 64 are more dependable than others. Early models will appeal to people who want something slightly challenging to repair, while a newer model is definitely better for someone who wants a retro machine that works without putting up a fuss.

Dave Farquhar Retail

The retail market is certainly changing and there’s a lot of consolidation in the market. But some retail categories have pretty much dried up on a national level, like toy stores. It ought to be a safe market, because new kids are born every year to replace kids who become adults. What’s behind the decline of toy stores?

While there’s been a degree of mismanagement involved in the decline of the two most recent toy store chains to go belly-up, both Toys R Us and Kay-Bee Toys had something else in common, and it wasn’t Amazon.

Authenticated scans across multiple domains

I helped a company troubleshoot its vulnerability scans recently. They had multiple Windows domains because of their line of business. This made scans difficult, but we found some solutions. Here are some tips for authenticated scans across multiple domains.

Scanning multiple domains in a single scan can cause account lockouts if the usernames and passwords don’t all match. Possible solutions include separating each domain into its own scan, using completely unique accounts to scan, syncing up the accounts so they have the same username and password, or using Cyber-Ark to match up credentials to machines.

Youtube says click to enable video converter? Here’s the fix.

My son had problems with his computer. Any time he went to Youtube, instead of getting video, he got a prompt that said “Click to enable video converter.” Virus is a strong word, but video converter is software you don’t want. Here’s how to fix it.

Run Malwarebytes, let it scan your system, quarantine everything it doesn’t like, then reboot. That’s all it takes to remove Video Converter. Don’t waste your time with those other websites that give generic information that doesn’t work.

Maximum grade for Lionel trains

Dave Farquhar Toy trains

What’s the maximum grade for Lionel trains? What’s the recommended grade for Lionel trains? The two are very different, and the first really depends on what compromises you are willing to make.

Generally speaking it’s best to go with a 2-2.5 percent grade on elevations with Lionel trains. But you can push it, if you’re feeling lucky. The shorter the trains you are willing to run and the more actively you are willing to adjust the throttle, the higher the grade you can get away with.
