Why You Shouldn’t Share Your Internet Connection With Neighbors

Thursday, December 29th, 2011

Wireless TowerIn the linked article, Kim Komando gives several good reasons for not sharing your wireless internet connection with neighbors. An important one being that if the neighbor does anything illegal, the police arrest you and confiscate your computer equipment. (On the other hand, if you’re the one doing illegal stuff over the internet, I’ve actually heard people suggest that it’s a good idea to leave your wireless router unsecured—so there’s reasonable doubt concerning who performed the crime.)

Stupid User Stories

Tuesday, December 27th, 2011

Any Key

The linked article has 10 stupid computer user stories, told by a computer support person. Many of them are too old to be relevant in today’s computer-savvy world, but my favorite is “The janitor’s closet”.

A Short History of Ethernet

Saturday, December 24th, 2011

Network CableThe linked article gives a (slightly) technical history of the Ethernet protocol, which these days is almost ubiquitous for wired LANs. It also explains how Ethernet works compared to other networking strategies. Somehow, fast transfer speeds arise out of seemingly total chaos. If you’re technically inclined, I think you’ll enjoy reading this article.

Cephalopods, the Masters of Camouflage [Video]

Friday, December 23rd, 2011

Camouflaged PenguinCephalopods (squid, octopuses, and cuttlefish) are very, very good at camouflaging themselves—it’s their primary method of protection from predators. But just how good is shown in the linked video, where an octopus is hiding. The word “unbelievable” is appropriate.

Thanks to Josh for this link.

Dealing With a Window That’s Outside the Display Area

Thursday, December 22nd, 2011

Tip JarSome time ago, I had a computer program that would occasionally glitch and set its location to be somewhere off the screen. The program would run fine and would show up on the taskbar, but I couldn’t access it with my mouse because it was outside the visible area of the Windows desktop. Eventually I discovered the technique described in the linked article. This is a command that’s been around for a long time but isn’t obvious to the casual user, especially the part about using the arrow keys to perform the movement.

A Round-the-Clock Solar Power Plant

Tuesday, December 20th, 2011

Recycle LogoOne of the problems with alternative energy sources such as wind and solar is their intermittent nature. Sometimes the wind is blowing and sometimes it isn’t. And the sun goes down every night. This is one of the reasons why fossil fuel plants are still a mainstay for any major power utility.

This problem has led to a quest for ways to store energy such that an alternative fuel power plant can supply energy on demand. One such method uses compressed air, while another has large batteries. More recently, a company named SolarReserve has received a $737 million loan guarantee from the US government for the construction of a round-the-clock solar power plant in Nevada—a plant that uses molten salt to store energy accumulated during daylight hours.

Why a 99-Cent E-book Can Make Financial Sense

Monday, December 19th, 2011

KindleThere’s just something magical about buying a product for 99¢. And in the digital world, where the cost of producing another copy is essentially zero, you can make serious money from a quality item that’s priced at 99¢. Steve Jobs figured this out, and it’s part of what made the iTunes Store so popular. Later, when the music labels wanted to raise the price slightly on newer songs, he fought them tooth and nail, saying that even a small price increase would ruin things. The labels won that battle, but that doesn’t have to be the case with self-published books on Amazon. The profit on a 99¢ book is 35¢, and it really adds up if you sell a few hundred thousand copies. The linked article is a bit old, but it reinforces the benefits of this sales model where you sell many, many digital copies of an item for a low price. The author of the article, for instance, saw his sales of The List go up by a factor of 20 (to 800 per day) when he dropped the price from $2.99 to 99¢. (I do find it funny, however, that the price is now back to $2.99.)

Netflix Makes a Mistake

Friday, December 16th, 2011

DiscIt’s a common belief: if you raise prices then income will also increase. But this isn’t always true. Earlier this year, Netflix, the DVD and streaming movie provider known for it’s affordable prices, made some changes to its pricing structure. They lost 800,000 customers as a result. Their stock price plunged, and they may be in the red for most of the next year.

The Amazon Kindle Fire

Tuesday, December 13th, 2011

Tablet ComputerHere at the Chad’s News network command center, we were the surprised recipient of an Amazon Kindle Fire—Amazon’s entry into the tablet market. After using it for a few weeks and reading some of the reviews, here are some comments:

The Kindle Fire is NOT an iPad. You won’t see all the features that you get in an iPad. But at something like 40 percent of the cost, this is to be expected.

The Kindle Fire is tightly integrated with the Amazon store. It doesn’t support the EPUB format, so forget about getting books through any venue other than Amazon. And even though it’s an Android device, you can’t purchase apps from the Android Market; instead, you have to use the Amazon App Store which contains a subset of the apps found elsewhere. (This is because the Kindle Fire, while based on Android, is not a fully-compatible Android device. So some apps won’t work on it.)

Storage space is limited, and you can’t attach an SD card to increase it. So storing videos or large music libraries on the device isn’t really an option. Most videos will need to be streamed.

All this being said, the Kindle Fire is a great device if you want an e-book reader with internet, multimedia, and apps. I’ve been having a ball with the Scrabble app. And while one reviewer thinks it will take over the entire low-end and middle of the tablet market, I think it may see some competition from the Nook Tablet.

One thing I really like is that the Denver Public Library has Kindle books that I can check out and read on my device. Way cool!
