If you need to know how to rent a house with bad credit, it’s possible. You have an uphill climb, but renting a home with bad credit isn’t a completely hopeless cause. Here are some tips from a landlord.

How do I know it’s an uphill climb? Other landlords ask me if I’d rent to someone with bad credit. But what I’d tell you is probably more valuable to you than what I tell them.

Commodore RAM expansion units

The 6502-family CPUs in Commodore 8-bit computers famously used 64K of RAM at a time. But in 1985, Commodore introduced a cartridge that added up to 512K of RAM to the 128. Commodore followed up soon after with a 256K cartridge for the 64. How did Commodore RAM expansion units work?

Fix gaps in laminate floor

Dave Farquhar DIY August 24, 2017August 12, 2017

Sometimes the locking system on laminate floor fails over time. When this happens, the piece slides around, leaving a big, unslightly gap in the floor. Tearing the floor up and replacing the worn-out pieces takes a lot of time and runs the risk of creating more damage. When this happens, here’s how to easily fix gaps in laminate floor.

You will want to fix these gaps sooner, rather than later. Gaps in laminate floor increase the risk of gouging the individual pieces.

Most valuable rookie card

When it comes to baseball cards, rookie cards are usually more valuable than non-rookie cards. But when we think of the Pantheon of valuable baseball cards, they tend not to be rookies. Instead, they tend to be scarce cards from hugely popular, iconic sets. The T206 Wagner. The 1933 Goudey Lajoie. The 1952 Topps Mantle. So what is the most valuable rookie card?

Cheap kitchen backsplash ideas

Dave Farquhar DIY August 22, 2017March 13, 2021caulk, home improvement, kitchens

If you need cheap kitchen backsplash ideas, I have one idea that’s cheaper than any of the others I’ve seen: Fiber-Reinforced Plastic, or FRP. With FRP, you can knock out a backsplash with less than $50 worth of materials.

It’s not the best looking material but it’s cheap, easy to work with, and readily available. It will do a good job for you until you can get something better. It’s both cheaper and more durable than many cheap kitchen backsplash ideas I see elsewhere. And since I said ideas, I’ll share one more idea I like a little less, but it’s clever.

Is TP-Link good?

You’ve probably seen TP-Link network equipment on computer store shelves, but it’s possible you’ve never bought any. TP-Link hasn’t been around as long as other brands, after all. But I don’t blame you for wondering: Is TP-Link good?

I like their stuff and recommend it. Here’s why.

Wondering about scale vs gauge? You’re not alone. It’s a common question, and I’ll try to provide a simple answer. The two terms may appear interchangeable, but they aren’t quite.

Finding and blocking an abusive host from your Apache log

My web site slowed to a crawl last night, my CPU usage soared to 100%, and my built-in security measures weren’t helping. I ended up having to do some old-school Linux sysadmin work to stop them.

I haven’t been an everyday sysadmin since 2009. But every once in a while I can still come off the bench and do this stuff.

Windows versions from XP onward include a built in firewall. But is Windows Firewall enough protection?

Yes. And no. Security answers are almost always complicated. But I’ll explain.
