Music Mini Course: Learn The Basics Of Reading Music On A Keyboard Instrument
Submitted Sunday, March 18, 2007 / Views 469 / Comment (299)
Welcome to the wonderful world of music. As you begin reading this Music Mini Course it is fun to realize that you are also participating in a very important cultural aspect from around the world which has been going on for centuries. Did you know that pianos in some form have been around for over 500 years? Some of the first instruments of this kind were created in the late Medieval Period and were called clavichords. They had a very light, metallic sound because the small hand-pounded 'hammers' were made of very light weight metal-like material. These hammers struck strings of varying lengths to create different tones or pitches. The next cousin to the clavichord was the harpsichord invented by Cristofori in Italy around 1450 A.D. This keyboard instrument had a mechanism in it called the plecktrum which 'plucked' the strings and produced a slightly stronger sound than its predecessor. Whether you are playing an acoustic instrument, which is the closest relative to the history just mentioned, or an electronic keyboard, you are now participating in a centuries old musical art form.

Device Driver Basics
Submitted Friday, March 16, 2007 / Views 126 / Comment (4)
Most people understand that the "hardware" part of their computer is the real physical parts, like the keyboard, mouse, modem, hard drive and so on. They understand that the "software" is computer bits stored on the hard drive, CD-ROM, or other storage media. But most people are a little hazy about exactly what a "driver" is.
In this article, I'm going to reveal in plain English what a driver is, why we need drivers, and exactly where the drivers are hiding. To give you a basic understanding, I'm going to go back, way back, to the early days of computers.
The Early Days
The year is 1981 and the world is in the midst of a severe resession. IBM's main frame business has slowed and the company is losing money. Up until now they had been laughing at the array of microcomputers on the market: Atari, Commodore, sinclair. Toys really, mostly used to play computer games.
The problem was, these "toys" were selling like hot cakes. IBM had to get into that market and get into it fast. They didn't have time to design and build a computer complete enough to compete in the market, so they built an "open system". They used commonly available electronic components and they published every design detail (including the code), and they even provided plug in slots so that others could build components for their computer.

Beyond the Box with Googles Web API
Submitted Friday, March 16, 2007 / Views 58 / Comment (0)
Google, the most popular, and many say best, search engine, offers searchers many options to help them zero in on just what they're looking for. Although these search modifier features are documented on own site, many searchers, including experienced marketers and technically savvy people, simple don't know these features are available. But these features, along with the Google search box, are only available to human searchers, who can type in their search parameters, and perhaps some keyboard scripting programs as well. But there is a way for programmers and web site designers to access Google's database from their own sites, in the exact way they need. This is done by using Google's Web API (Application Program Interface).
With the API, programmers can use most any web programming language, such as PHP, ASP, Perl, .NET, and Java. Google's Web API provides "data hooks" that allow a remote program to access certain portions of Google easily.
You must be very aware of the Google Web API Terms of Service. You must obtain a developer key that you will include in each API use, you are allowed only 1,000 automated queries per day, and perhaps most important, you may not use the Google API for commercial purposes. It is only for your personal use, and you of course may not violate any laws or copyright protection.

Google Wireless - Search Away From Home
Submitted Friday, March 16, 2007 / Views 50 / Comment (0)
For so many web surfers, it's almost automatic to type Google.com in to our address bar when we want to search. So big and well-known is Google that many browsers have a built-in search box or typed shortcut for Google searches. In fact, we tend to associate Google with search so much now that the word itself is commonly used as a verb, as in "let me Google that". It's much the same as Band-Aid, Kleenex, and Xerox, where the brand name is so pervasive that it's very often substituted for the generic function of the item the brand is applied to.
We're used to searching from home, where we've had Internet access for years now. But Google Wireless search is also available for use from Internet-ready cell phones and some wireless PDA devices such as PalmOne and Palm VII.
To search from Google Wireless, you will need access to the Internet through your wireless device. This can usually be arranged through your cellular carrier if you don't already have it. You can search the "mobile web", which is a collection of web pages that have been designed specifically for wireless devices. With Google Wireless search, you can also search all of Google, and the search results will be translated into a type of display language that your mobile device can interpret.

DMOZ: Rotten To The Core
Submitted Friday, March 16, 2007 / Views 65 / Comment (2)
I knew things were bad at DMOZ. But I guess I didn't realize how bad, until I started eavesdropping on a few forums, and reading the avalanche of e-mails I received on the subject.
When it takes up to two years to get a web site listed, there's a serious problem. When perfectly qualified web sites are rejected for no other reason than the fact the editor considers them serious competition to his or her own site, there's a serious problem.
When you e-mail DMOZ about the status of your web site and don't even receive a courtesy response to your questions, there's a serious problem.
When you have egotistical DMOZ editors fighting each other to have their own web sites listed, there's a serious problem.
And quite frankly, I don't see how the mess DMOZ has created can be fixed. With an apparently endless backlog of web sites waiting to be approved, how can they possibly catch up. The answer is, they can't.
But this isn't just a performance issue we're talking about here, this is a morality issue. The very fact that it's a matter of public record what DMOZ is doing speaks volumes about the character of many of their editors.
