Add a case fan to a Dell Optiplex

Dell Optiplex minitowers aren’t really designed with adding case fans in mind. But with a little creativity, you can install one inexpensively, and without making it too terribly much louder either. Here’s how.

With a power adapter, an 80mm fan, and some zip ties, it’s possible to add a case fan to a Dell Optiplex. The opening in the side panel is in just the right place for even a small fan to make a difference.

Drill vs impact driver

Drill vs impact driver

Drills and impact drivers look a lot alike, but they’re really different tools for different purposes. One of them is an absolute must-have, while the other is, for most people, a nice-to-have. Let’s take a look at a drill vs impact driver.

How to unschedule a WordPress post

I tend to schedule a lot of posts in advance. At least when I get on a roll, that is. But sometimes you schedule a post, then have second thoughts about it being ready to run. I’ve certainly run more than a few posts before I intended to. Here’s how to unschedule a WordPress post.

It doesn’t look like setting the post status to draft actually unschedules it. Looks can be deceiving, so here’s how to be sure.

Laser 128 computer

The Laser 128 computer was an Apple II-compatible home computer manufactured by Video Technologies Ltd in Hong Kong and sold in the 1980s. It was available via mail order and in some retail stores like Sears. In spite of the name, there wasn’t anything optical about it. The name “laser” just sounded like high technology in the 1980s.

The Laser 128 was an Apple II clone most noteworthy for not violating any of Apple’s copyrights. It blended some of the features of both the Apple IIe and IIc computers, improving significantly on the IIc in the process.

Can you download RAM?

Can you download RAM?

A software developer asked me about a website called Download More RAM. I don’t think he heard my other coworkers snicker. He asked if it was a security issue, while missing the even more important question: Can you download RAM? I said it’s best not to visit the site, and spared him the history lesson.

Downloading RAM isn’t possible because RAM is physical hardware–computer chips on a circuit board. You can only download software. But still, the sites remain.

RAM Doubler remembered

RAM Doubler was a fairly popular product for Macintosh computers in the 1990s. But you can’t buy it today, and if it seems like it’s been a while since you’ve seen or heard of it, there’s a reason for it. Ironically, it was a competing product that didn’t work that brought it down. Here’s what happened to RAM Doubler.

RAM Doubling products worked by setting aside an area of memory and compressing it, then decompressing it when you needed it. It was a form of virtual memory, theoretically faster than traditional virtual memory that used disk space, but less stable.
