Can you use a Dell charger on an HP laptop? Or vice versa? I don’t recommend it, but sometimes you can. In a pinch, that’s better than not being able to use your laptop at all. Here’s how to tell.

Is gigabit Internet worth it?
Is gigabit Internet worth it? I want gigabit Internet. I wanted it for a really long time before I was able to get it. And not everyone can. Here’s why I want gigabit Internet and how I can justify it. If you can get it, it’s worth considering. Here’s why it might make sense for you.

Does laser printer toner expire? Not really.
Laser printer toner doesn’t dry out like inkjet ink does. But does it go bad? Does laser printer toner expire?
There is a use-by date on some toner cartridges. But in my experience, you don’t have to worry about it very much.
How to find my router IP
It’s hard to know how to find my router IP address, since it’s arbitrary. Usually your router lives at one end or the other of your network, but there’s no reason why it has to. So if someone decided to get tricky, here’s how to find it.
There was a time when knowing your router IP was a matter of survival, but these days networking normally configures itself, using a technology called DHCP. That puts your router IP address out of sight and out of mind. But it turns out there are several ways to find the router IP, and some of them work no matter what kind of computer you have.
Extract a MAC address from Excel data
A vulnerability scanner like Nessus or Qualys will record the MAC address of every computer it finds. But Qualys doesn’t output the MAC address in a nice column format. It mixes a lot of other data into the cell. So I had to figure out how to extract a MAC address from Excel data to give an infrastructure team an inventory they wanted.
An announcement regarding Facebook and this blog
Effective Aug 1, I won’t be able to post updates from the blog to my Facebook profile automatically. So if you follow me on Facebook, you won’t see blog posts after Aug 1. I have set up a Facebook page where I will be able to continue to post updates. If you’re interested in following this blog on Facebook, follow this page instead of me. If you want to watch me rant with my journalism school classmates from the 1990s, follow me.
And now I have two days to get posting to that page working. Wish me luck.
AT&T vs Spectrum Internet
I’ve had high speed Internet for about as long as anyone in my ZIP code–as soon as DSL was available, I signed up and paid through the nose for it. It took a while for fiber to become an option, but I switched once I did. I’ve been a Southwestern Bell/AT&T customer for a good 17 years. Over the years I weighed it and AT&T vs Spectrum Internet.
I switched to Spectrum in 2016, then back to AT&T in 2018. There are pros and cons to each of them, so I thought going through them might be helpful. Keep in mind Spectrum encompasses several legacy companies. Charter Communications started re-branding itself as Spectrum soon before it acquired Time Warner Cable and Bright House Networks. Of the three, only Bright House Networks had a good reputation. Hence the use of the new name.
Commodore Plus 4 and Commodore 16
Dan Bowman kindly pointed me to former Commodore engineer Bil Herd’s discussion of the ill-fated Commodore TED machines on Hackaday. Here in the States, few remember the TED specifically, but some people may remember that oddball Commodore Plus 4 that closeout companies sold for $79 in 1985 and 1986. The Commodore Plus 4 was one of those TED machines. So was the Commodore 16.
What went wrong with those machines? Commodore miscalculated what the market was doing. The TED was a solution to too many problems, and ended up not solving any of them all that well. Read more
AOL history
AOL, also known as America Online, wasn’t the first online service. But it became the biggest and most popular one. For many people of a certain age, AOL was their first experience with a modem, or with the Internet. Let’s take a look back at AOL history and how its legacy affects things even today.
AOL long had a reputation as a place where inexperienced, unsophisticated computer users hung out, but the company had a long streak of innovation and was ahead of its time in many regards. I’ll bet you had no idea the history of America Online begins way back in 1983. And you may also be surprised to hear the company still exists, though in a different form, even today.
How to use your own router with AT&T U-verse or AT&T Fiber
AT&T provides a residential gateway when you subscribe to U-Verse or AT&T Fiber. It’s pretty easy to use, but lacks a lot of features we expect in routers these days. So you may be wondering: Can I use my own router with AT&T U-Verse? Yes. Yes you can. Here’s how to use your own router with AT&T U-Verse or AT&T Fiber.
