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.
Drills are for drilling holes and driving in small fasteners. Impact drivers, which are more powerful and tend to cost more, are for driving in large fasteners.
I’ve found Python is a useful skill in the workplace. It took me a little while to learn it, but it turned out to be easier than I thought it would be. Here’s why I learned Python, and I think anyone who works in IT should at least consider learning it.
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.
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.
Other Apple II clones usually violated Apple’s copyrights, but the Laser 128 did not. It blended some of the features of both the Apple IIe and IIc computers.
About once a year, this Mac I’m supposed to use for work develops issues with its Bluetooth not working. Since I sometimes spend six hours in Zoom meetings in a given day, that’s a problem. Since this isn’t well documented anywhere, here’s how I fix Bluetooth audio not working on a Mac.
The most reliable fix for Bluetoooth audio issues on a Mac for me, by far, has been deleting the Bluetooth devices and then pairing them again.
The Lionel e-unit was a wonder of ingenuity in the 1930s. But how does a Lionel e-unit work?
Is the Linksys WRT54G obsolete? Depending on how many devices you have and how fast your upstream connection is, it may be.
I had an issue with my Windows 10 Start Menu not working when I click on the Windows button on the screen or my keyboard, on two separate machines within two days of each other. The fix is easy enough but most people way overcomplicate it. Here’s the no-bull guide to fixing the Windows 10 Start Menu.
To fix the Windows 10 Start Menu, all you need to do is restart Windows Explorer from Task Manager. You can fix it in 30 seconds or less and get on with your day.
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 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.
