Share a Windows 10 printer by UNC

Windows 10 uses homegroups, but if you have systems that don’t understand homegroups and want to share a Windows 10 printer by UNC (the old school way to share a network printer), it’s not obvious how to go about doing it.

I couldn’t find a way from the GUI, but it’s still possible to share the printer from a command line.

Linksys EA6200 DD-WRT installation

I picked up a couple of refurbished Linksys EA6200 routers this past weekend. For whatever reason, DD-WRT isn’t officially supported on them, though it does seem to be a popular DD-WRT router. A lot of people make the upgrade far more difficult than they need to. With some simple hacks, Linksys EA6200 DD-WRT installation is pretty straightforward.

I came up with an 18-step process that I simplified just as much as I could. Unlike some methods I’ve seen, I don’t have you editing any binary files or creating custom startup scripts.

Advantages and disadvantages of Windows 3.0

I hear the question from time to time what the advantages and disadvantages of Windows 3.0 were. Windows 3.0, released in May 1990, is generally considered the first usable version of Windows. The oft-repeated advice to always wait for Microsoft’s version 3 is a direct reference to Windows 3.0 that still gets repeated today, frequently.

Although Windows 3.0 is clumsy by today’s standards, in 1990 it had the right combination of everything to take the world by storm.

Download more RAM — Safe? Scam? Joke?

A software developer asked me today about a website called Download More RAM. I don’t think he heard my other coworkers snicker. He asked if it’s possible to download RAM, then asked if it was a security issue. I said it’s best not to visit it, and spared him the history lesson.

Yes, there’s some history to it.

When DD-WRT doesn’t work with Charter

I set up a DD-WRT router on Charter’s Spectrum broadband, and had a hard time getting it to work. It wouldn’t pull an IP address on the WAN side, or it would pull a 192.168 address rather than a Charter public address.

Here’s what I had to do to fix it.

Why MAC address filtering doesn’t help security

The other question that came out of my recommended DD-WRT settings was why not filter MAC addresses. I hate to be flip, but MAC address filtering doesn’t help, so why bother?

The reason is because your MAC addresses are broadcast as part of the network traffic, and it’s unencrypted. So your MAC addresses aren’t any secret at all. So it doesn’t do any good. One could argue it doesn’t do any harm. But it adds an extra step every time you put something on your wireless network. Why go to the inconvenience if you don’t gain anything from it?

Move Debian to new hardware without messing up networking

One advantage that Linux has over Windows is that you generally can pick up a machine and move it to new hardware. The trickiest part is getting the network card(s) working.

Maybe I’m the only dummy who had a hard time with this. Well, except for one guy who posted a question somewhere, got no answer, then came back and said something rude to the people who didn’t answer and said he switched to FreeBSD. That was entertaining, but not helpful.

Just in case everyone else is afraid to speak up, here’s how I got the network cards working after I imaged the disks from a failing Debian server to newer hardware.

Recommended DD-WRT settings

I’ve been asked a few times now for my recommended DD-WRT settings, or at least my good-enough settings. I think that’s a great idea, so I’ll walk through how I configure a DD-WRT router. Follow these steps and I can almost guarantee you’ll have the most secure network on your block.

For the purposes of this tutorial, I am going to assume you are configuring DD-WRT as your primary router.

How to make your online banking more secure

If you want to make your online banking more secure, I have a tip for you.

Due to the increasing amount of malware targeting bank accounts, it’s not a bad idea to dedicate a computer to online banking and only online banking. Of course, who wants to dedicate an expensive computer to that task?

You don’t have to. You can buy a $120 refurbished Chromebook to use. If you don’t want to spend any money but have a seldom-used computer still hanging around that isn’t good for much, load Linux Mint on it and use it exclusively for banking. My experience with Mint on an old netbook has been rather good. Linux Mint is, if anything, easier to get up and running than Windows.
