I gave Go Launcher Ex a whirl on my hacked Nook Color-turned-tablet. The promise was that it’s faster and smoother than ADW Launcher, the default program launcher that comes with Cyanogenmod. Unlike some promises, it was true. It’s fast, smooth, polished, and customizable.
I was a little apprehensive at first–how does one go about changing something so fundamental as the program launcher–but it was easy.
I always burn in my computers. But how do you burn-in an Android?
Here’s what burn-in means, if you’re unaware. When you first buy a computer, the very best thing you can do for it is leave it on for 24 hours nonstop, preferably doing something that’s reasonably hard work. That practice is called burning in a computer. If there’s anything at all wrong with it, there’s a very good chance it will come up in that initial 24 hour period. I’ve been doing that for more than 20 years, and of all the computers I’ve owned in that timeframe–and it’s an army of them, believe me–I’ve only had one machine fail prematurely. One.
The practice works.
So what about a tablet or a smartphone?
Electrodroid is an Android app designed for electronics hobbyists, but it has uses for model railroaders too. Its LED calculator is invaluable when using LEDs to light buildings, cars, locomotive cabs or headlights, or for other projects. Knowing the input voltage, you can then determine what resistors to use to protect the LED.
The voltage drop calculator is useful too, if less obvious. Read more
One thing I’m seeing in the predictions-for-2013 columns is that mobile malware is going to increase this year. While I can’t be certain it’s going to happen, all of the ingredients are there. The only thing stopping it is motive.
I’m familiar with Avast antivirus on Android. It’s nice. Whenever I download an app from the Google Play store, it scans it, and if it finds something it doesn’t like, it intervenes. Read more
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.
The biggest problem with making custom (or reproduction) decals for use with trains of the miniature variety is getting the colors on the computer-generated decal to match the paint on the model. Eyeballing the color won’t work; you need a computer’s help to do it.
Enter a free Android app called Color Eye. Launch Color Eye, point your phone or tablet’s camera at the paint you need to match, and your phone will give you the closest color matches that it knows about, including a Pantone color and a CYMK value.
My mother in law didn’t have wifi set up, but she picked up a smart TV this year, so she asked me if I could help her with it. So I picked up a D-Link DIR-615 on sale, brought it with me and set up wi-fi securely (hints: set the SSID to whatever time it happens to be, disable WPS, disable WEP and WPA, and use WPA2 with a long password with some numbers and symbols in it) and once it seemed to be working right, I put her TV and laptop on it. Then, as other relatives trickled in, they asked me for the wireless key. Soon the air was full of Androids and Apples chattering away on wireless.
It’s not news to my regular readers that SSD pricing continues to drop, but Computerworld noticed that this week.
Everyday pricing is well around 90 cents per gigabyte now, and with some shopping around, it’s possible to do better than that.
I picked up a couple of the new Philips 10.5-watt 800-lumen LED bulbs this weekend. All around, they’re the best sub-$20 LED bulb I’ve seen yet.
For some reason, Microsoft decided several years ago that they needed to market a vector drawing program. It flopped. There may have been several reasons for it, but I’m sure one of the reasons was marketing.
At any rate, they decided to discontinue the product and offer it for free download. Read more
