Add a TCP/IP printer in Windows 10

Sometimes you have to manually add a TCP/IP printer in Windows 10. For example, I have an older HP Laserjet 4100 with a Jetdirect card in it that I use to print from all of my PCs over my local area network (LAN). Getting Windows 10 to print to it isn’t difficult but it’s hardly intuitive.

If you have your printer already set up but just need to change its IP address, I covered that here. If you want to share a locally attached printer with other computers on your network, you can do that too.

The wrong way to reboot a server

In my day, I did plenty of hardware maintenance in the field. In fact, the only time one of my bosses ever saw me working, I was swapping out failed memory in a server.

“How’d you know it needed to be done?” he asked.

“It told me.” That’s why I always loved HP Proliant servers. My boss looked confused at my answer but didn’t ask me to elaborate.

But not all of my field maintenance always went quite so smoothly. Continue reading The wrong way to reboot a server

How to ditch your landline and your phone bill but still have phones that work

Now here’s a potentially huge money-saver. I still have phone service through AT&T that rings through old-fashioned phones (you know, like the kind you see in a museum) because there’s nobody that’s going to give me a wireless plan with unlimited minutes for about 30 bucks a month.

But, still, that’s $360 a year. I’m sure there are things I’d rather do with $360 a year if I could free that up, right?

What if I were to tell you that you could buy a device that costs less than $100 (potentially as little as $38) and you could make phone calls for free using your Internet connection?

An update on the shortcut to wiring a house with Ethernet

Last week, I presented a shortcut for wiring a house with Ethernet using cheap keystone couplers. I’m happy to say I’ve done it twice now, and it all works, but I wanted to follow up and share a little more experience now that I’ve wired about a dozen ports this way.

Remembering Michelangelo

Yesterday was the 20th anniversary of the Michelangelo virus. If you don’t remember, on March 6, 1992, Michelangelo was programmed to overwrite the first 100 sectors of a hard drive–not quite as destructive as formatting a drive, but to the average user, the effect is the same. It was a huge scare–John McAfee predicted five million computers would be affected–but largely was a non-event.

Those of you studying for security certifications would do well to remember that Michelangelo is a prime example of a virus and a logic bomb. Viruses replicate; logic bombs do something when an event triggers. Malware doesn’t always fit neatly into specific categories–crossovers are common.

I have a server… and about four years’ worth of content

My new server is up and running, and let me tell you, it’s spectacular.

And if you’re reading this on 6 March 2012, you’re probably wondering what I’m talking about, because everything looks just as slow as usual. That’s because the new server is still behind my firewall because I’m struggling to get my content all moved to it.

Nginx, a leaner, meaner web server

Arstechnica posted a nice writeup on Nginx, a cut-down webserver that does less than Apache does, but does the few things it does much faster. That’s nothing particularly new, as smaller and faster webservers have existed for as long as I can remember.

What makes Nginx different is that it can work with PHP. And therefore, it can run WordPress.

Cheap laptops and tablets: September 2011

My brother in law told me he saw an 8-inch Vizio wifi-only tablet running Android at Costco for $285. Its reviews aren’t exactly stellar, but if you just want a basic tablet, it seems to be OK. I’d wait a few months and see what Amazon’s tablet plans are, though.

He also asked about laptops. And there’s some good stuff going on in the low end there too.

How to power your computer up from away from home

The low-tier, DIY VPN has proven popular. The biggest drawback with its approach has been that it requires you to keep a PC on at home. But if your computer is configured to hibernate after a period of inactivity, or if the power goes out, you’ll have a problem.

If you’re willing to do some work, you can use Wake-on-LAN over any Internet connection to solve that issue and power on the computer at will.
