Sometimes you need to ping sweep a network. I have a batch file for that, but what if your list isn’t continuous? In that case, there’s a better tool for you. Pinginfoview is my favorite free Windows ping sweep tool. It’s easy to use, small, and standalone, requiring no installation. In this blog post, I’ll explain why it’s so great.
Masterforce is Menards’ house brand for power tools and hand tools. As a house brand, they are less expensive than the big name brands. But are Masterforce power tools good? And who makes Masterforce power tools for Menards? I did some digging to find out.
Masterforce power tools are made by Chervon, one of the 10 largest OEMs of power tools in the world. Contrary to rumor, they are not rebadged Maktec tools made by Makita.
ZIP and RAR are two popular file formats in the Windows world. They have similarities, since both of them provide lossless file compression. But they have some fairly significant technical and philosophical differences too. Here’s a look at ZIP vs RAR and why the two file formats have coexisted side by side for decades.
XXCOPY vs XCOPY: Which file copy utility do you like? Both of them are extensions of the DOS command COPY. Think eXtended Copy and eXtended eXtended Copy. Two extendeds are better, right? Yep.
Modern tamper resistant outlets are a good safety feature, but they also present a challenge. They can be much harder to plug into. Here’s how to open tamper resistant outlets if you can’t plug into an outlet.
Dealing with JSON is a common task when you’re coding in Python. Two functions you may use a lot without fully understanding them are json.loads and json.dumps. Let’s take a look at json.loads vs json.dumps in Python, what they do, and how they can help you, especially when wrangling complex JSON data from APIs.
json.loads and json.dumps are two functions in Python for converting JSON to and from simple strings. Sometimes one is better than the other, and being able to convert between them reduces the trade-offs you have to make.
Payless Cashways, not to be confused with the shoe store with the similar name, was a regional hardware store, based out of Kansas City. Much like its cross-state neighbor, Central Hardware, it pioneered the big box home improvement store format, featuring a real lumberyard. It, too, was in a poor position to capitalize on the booming home improvement market. It went out of business September 10, 2001, after 71 years of existence.
Payless Cashways was born out of the Great Depression and grew as a result of the post-World War II boom in DIY home improvement. But the threat of takeover by a corporate raider in the 1980s ultimately proved its undoing.
Retailers started pushing electric mowers hard in 2021. When I walked into Home Depot at the beginning of March, I saw more electrics on display than gas-powered mowers. Even Harbor Freight, of all places, has two electric mowers on prominent display. But are electric mowers worth the money? Let’s look at whether a gas or electric mower makes more sense.
If you’re in the market for a mower anyway, an electric mower makes a ton of sense because it’s cheaper to operate than a gas mower. If you have a working gas mower, the numbers are murkier but electric may still make sense.
I’ve been driving a hybrid car for almost five years. If I’d had my way, I would have bought one much earlier, back in 2003, but I just couldn’t afford one then. Are hybrid cars worth it?
Driving a hybrid saves you around $400 a year in fuel costs. That makes it difficult to recoup the higher cost of a hybrid when buying new, but it makes used hybrids a bargain, since the resale value of a hybrid is comparable to an equivalent conventional car.
I got shocked by a neutral wire on an outlet that was shut off at the panel once. That doesn’t make any sense. It’s a rare condition, but it can happen. It shouldn’t happen, but here’s why a neutral wire can shock you.
