Spammers Profit Despite Low Response

The BBC has an interesting article on the types of profit that spammers can see in the field.

I often get asked how spammers can make a profit when so many spam emails are obvious scams. The answer comes from the fact that spammers can send out millions of emails with little cost, meaning that even an incredibly small number of people responding can mean they make money.

In fact, the article states that the bad guys are “turning a profit despite only getting one response for every 12.5m e-mails they send.”

Making Your Own Holiday Light Show

[kml_flashembed movie="" width="450" height="375" wmode="transparent" /]

If you remember the videos a few years back of elaborate Christmas light shows synced to music, you may have wondered how you could do something similar for your own holiday decorations.

In the process of planning my own Halloween decorations, I discovered that there’s an entire industry that has sprung up around helping make displays like that possible for anyone, with the only limit being the time and money you want to invest.

Now, instead of hand-built electronics, you can buy unassembled light controller component kits from companies such as Light-O-Rama or D-Light Designs. Prices for 16-channel kits range from $120 and up, with pre-assembled kits being as cheap as $200.

To create your computerized light show, you’ll need sequencer software. The program I used for my own Halloween light show is called Aurora, available for purchase for $100, though there are a wide range of programs at different price points, including some free, no-frills command-line programs.

If you don’t have the time to create a light show and sync it to music, you can even find pre-programmed sequences from companies such as WowLights Productions, along with a number of other light show product packages.

Having assembled the pieces for my Halloween light show, I can say that it’s definitely not a cheap holiday project, but I can say that the sense of satisfaction when the lights come alive and dance to the music I’ve synced them to makes it worth every dollar I’ve spent.

The Meister House Graveyard 2008

We added a little light show to the Meister House’s Halloween display this year, and after much work, it’s nearly complete!

The show is powered by Aurora software running a D-Light ACx16 controller.

Ultra-Compact Laptop Market: Small, but Growing

If you’ve been keeping up with currently available notebooks and laptop PCs, you may have noticed the new phenomenon that is netbooks, such as the Asus Eee PC or the Acer Aspire One. Also, Lenovo and Dell have both recently made announcements about their plans for ultra-compact notebooks. “Netbook” is a term often used to describe the new class of ultra-portable and inexpensive subnotebook computers that trade features such as DVD drives for reduced price and size.

I first came across this new class of portable computer when I began to look for a smaller form factor to take with me out into the field.

The idea of a reduced functionality laptop isn’t new, and dates back to
portables such as 1983’s Tandy Model 100. In the 20 years since then, a number of ultaportables have been released, though few caught on due to the premium prices that came with them.

Much of the current interest in netbooks comes from the excitement generated by the One Laptop per Child project’s goals to create a $100 laptop. While the project wasn’t as successful as it hoped, it did compel manufacturers to work on their own inexpensive and ultraportable devices.

The first of these attempts to take off came from ASUS in the form of their Eee PC netbooks released in 2007. The Eee 4G Surf series first came to the US in late 2007, with a sub $400 price point for most variants. Although there were complaints about the tiny keyboard and reduced-resolution screen, the paperback sized device sold better than anyone expected, prompting others to quickly begin work on their own entries.

Current competitors include the MSI Wind PC and the Acer Aspire One, which features the Intel Atom processor and is available at Best Buy for around $350.

While the price and size of netbooks are tempting, it’s still important to consider how you will use the device. If you often use your laptop to watch DVD movies, for example, you’re going to need to invest in an external USB DVD drive. And while the keyboards are improving, they do take some time to get used to and aren’t always the most productivity for long periods of word processing.

From my own experience as an owner of an Asus Eee PC, I’ve come to really like how portable the device is. Instead of a full-sized laptop bag, I can carry the system, complete with charger, USB hard drive and tools, in a portable DVD bag nearly half the size. While the Eee PC works great for most of the on-site troubleshooting tasks I need it for, the small keyboard does slow down my typing speed. I’ve also found the reduced 800 x 480 resolution LCD screen can also sometimes be a problem when surfing web sites for technical information.

Still, having a ultracompact and inexpensive device as a secondary PC does make it an easier decision on whether to take a PC with you when you’re away from the office or off to school. With the number of services available on the Internet, such as Google Docs, using that netbook as an on-the-go machine has really made the devices a solid option for the modern, highly mobile person.
