How I turned my Nook Color into a Cyanogenmod 7.2 Android tablet

Dave Farquhar Android, Hardware , , , , ,

So, after most of a year, I finally revisited Cyanogenmod 7.2 on my Nook Color. Competent tablets are available for around $100 now, so perhaps this is less interesting now, but I had a Nook Color, and figured I might as well try it out before spending money on something else.

I was never happy running it from an SD card–it was way too laggy and sluggish–but Cyanogenmod 7.2 is competent when installed on its internal memory, at least for the things I most want to use a tablet for–light web browsing, reading e-mail, watching SD video, and reading PDFs–and it leaves the SD card slot open for storing the media I want to consume.

What to make of this Black Friday’s sub-$200 laptops

It’s still a couple of weeks off, but we already know two retailers will be offering sub-$200 laptops on the day the United States gorges itself on bargains.

The question is, what do you get for your $200 on these minimalist laptops? I’ll answer those questions, then you can decide whether they’re worth $200 and braving the crowds, the weird hours, and likely the cold. (Yes, there are costs beyond the money you spend.) Read more

How to clean paint from outlet and switch covers

Earlier this year, I did some cosmetic fix-up of a house that, among other things, had a lot of painted-over outlet covers. Preventing that is easy–it takes a couple of minutes to unscrew the cover and put tape over the outlet–but if someone didn’t do that, the cleanup is cheap and easy too, even years after the painting mishap. And all you need are common household items to clean paint from outlet and switch covers or other types of wall plates.

Reduce your RAID failure rate

Dave Farquhar Hardware, security , , , ,

It’s not often that you end up talking about computer hardware at church. It’s especially not often that you end up talking about a RAID failure at church. But one such conversation got me thinking again about ways to reduce RAID failure rate.

This past Sunday, I talked with the executive director, who told me five of the drives in the 8-drive RAID array failed all at once. “That’s not supposed to happen,” he said.

It isn’t. But I know why it did.

Cable connections are the last thing most people check…

Dave Farquhar Hardware , , , , , , , , , ,

Fed up with trying to host a network printer on a Windows 7 box on a mixed network, I broke down and bought a Jetdirect card for my aged HP Laserjet 4100. Don’t worry–used Jetdirect cards are cheap these days. I paid $7 for mine.

Of course I made installing it harder than I needed to. I’m a professional. Don’t try this at home. Read more

How abandonware gets abandoned

Dave Farquhar Copyright, Retro Computing, Software , , , , , ,

From time to time on classic computing and/or videogaming forums, the question of how to track down the current copyright holder to a particular given title comes up. Sometimes someone knows the answer. Frequently they don’t.

This week, when George Lucas announced he’d sold Lucasfilm to Disney, illustrated precisely how this kind of thing happens.

A cheap upgrade for obsolete computer cases

Dave Farquhar Hardware , , ,

The ATX standard has changed very little in the last 15 years, which means some rather old computer cases can still accept new motherboards, as long as you also replace the power supply.

The bad news, as I stare at the case that once housed a Micron Client Pro 766 Xi (a 266 MHz Pentium II that was state of the art in 1997) is that front-mount USB ports were unheard of in those days, as were digital camera memory cards. Instead, machines of that era used obsolete floppy and Zip disks for removable storage. They also typically had more 5.25″ bays than we need today. When CD burners cost $400, most of us kept a reader in as well, to avoid wearing out expensive burners prematurely.

Hide and unhide whitespace, headers and footers in Microsoft Word

Dave Farquhar Office, Software , ,

For now at least, I edit a lot of security documents as part of my job. Today, I saw something I hadn’t seen before: Word 2010 was hiding all of the headers, footers, and whitespace in the document. That made navigating the document a whole lot faster and easier, but it also meant I couldn’t verify that the headers and footers were correct. I figured out how to hide and unhide whitespace, headers and footers in Microsoft Word.

The solution was simple but non-obvious, and works in all versions of Word that I know of. Read more
