Botnets are made up of large numbers of computers that malicious hackers have brought under their control after infecting them with so-called Trojan virus programs.
While most owners are oblivious to the infection, the networks of tens of thousands of computers are used to launch spam e-mail campaigns, denial-of-service attacks or online fraud schemes.

How does this happen? You'd be amazed at the number of people who have NO up-to-date antivirus software installed on their computer, or who have no firewalls. Are YOU one? Of course not. That's THOSE people, right? :-) Bottom line - YOU M-U-S-T have an up-to-date antivirus program on your computer and you M-U-S-T make sure you've got a firewall! Minimum!! Don't be part of the problem.

It then hit me. This is how I learn. It's my constant professional development. This is how I grow professionally. It's how I find out about best practices in student blogging and student use of wikis. It's how I stay engaged and connected in the conversation of education and the role of technology. And Ohhhhh was I missing it - even in that first minute.
And then I thought, "This is how those teachers in the districts feel - many of them - when they can't access the sites that they find at home that they feel are good resources for their kids. It's no wonder that so many of them are just saying, 'To heck with this. It's not worth the aggravation.' " It's no wonder I often find it difficult to excite them about technology.
The good news is that by the time the day was over I was again able to access my bloglines account and all my favorite blogs. I just can't imagine going to work and NOT being able to access my feeds. Can you?

Wikimedia is a site that encourages folks to upload and share their media files that they have created. No, not like YouTube. These are images, sounds, animations, etc, and are available for others to download and use under the Creative Commons license. There are sites all over the Internet that encourage the open sharing of content that is owned by the viewers. I've made a few of mine available under that license on the Flickr site. Most of my pictures aren't the kind that anyone else would want, but there are a few that others may like. Here's a wiki being used for the same type of thing.

"What is GeoGebra?
GeoGebra is a dynamic mathematics software for education in secondary schools that joins geometry, algebra and calculus.
On the one hand, GeoGebra is a dynamic geometry system. You can do constructions with points, vectors, segments, lines, conic sections as well as functions and change them dynamically afterwards.
On the other hand, equations and coordinates can be entered directly. Thus, GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions and offers commands like Root or Extremum.
These two views are characteristic of GeoGebra: an expression in the algebra window corresponds to an object in the geometry window and vice versa."

Do you know how long I've waited this year to send these? Two sites with images of extreme closeups of...SNOW!! It's 8 degrees in Harrisburg as I write this but last night was the first real snow of any kind that we've received this winter. Not that I'm complaining, mind you. I'm just sayin'.... :-)
A teachable moment about today's snow may find you searching for pictures of snowflakes. There you have two good sample sites. And you don't have to shovel either of them.

The evolution of teaching and learning is accelerated with technology. After several decades of duplicating classroom functionality with technology, new opportunities now exist to alter the spaces and structures of knowledge to align with both needs of learners today, and affordances of new tools and processes.
Yet our understanding of the impact on teaching and learning trails behind rapidly forming trends. What are critical trends? How does technology influence learning? Is learning fundamentally different today than when most prominent views of learning were first formulated (under the broad umbrellas of cognitivism, behaviourism, and constructivism)? Have the last 15 years of web, technology, and social trends altered the act of learning? How is knowledge itself, in a digital era, related to learning?

Here's a story that defies explanation:
http://news.sky.com/skynews/article/0,,70131-13564124,00.html?f=rss It goes something like this. A guy goes duck hunting a shoots a duck. He takes it home and throws it in his fridge. Two days later the wife goes to get it out and finds that it's still alive. Then... well, you'll just have to read it to find out. Suffice it to say that I'll bet the next time he shoots a duck he'll also strangle it for good measure. :-)

Descartes is an applet (a program written in Java) which can be configured. It has been designed to present educational interactive tasks with numbers, functions and graphs. Descartes can be used by creators of educational Web pages as a means of supplementing their material with a wide variety of interactive mathematic models.
Teachers can use Descartes to produce their own interactive Web pages, which cover a wide variety of subject areas within mathematics. For example, the following parabola graph has been created using the Descartes applet.

A QUICK tutorial
Once the applet loads, click the Config button in the top right corner.
Click the various radio buttons near the top of the resulting window to gain access to the variables and formulas
NOTE the animation button!!

Oh, long-time subscribers of my tips will recall a video from a short while ago in which the demonstrator showed off a new operating system where he moved things around with his hands, and enlarged then just by touching his pinched fingers to the screen and dragging them open. Here is the practical application of that system.
Education is one of the few things that people are willing to pay for and not get. - William Lowe Bryan

So, this is a heads up. If YOU use that neat little add-on for Word, either don't update your Blogger blog to version 2, or Uninstall that add-on FIRST.
Oh, and according to the website, they don't know if they'll make a version that will work with the new Blogger or not.

A defense was offered for the growth of German military expenditures based on the spread of "Slavik pride" and the rise of a "great Pan-Slavonic movement" due to "victory of their kinsmen in the Balkans". German leaders, furthermore, felt a deep uneasiness about the fact that about one-third of the population of the Hapsburg Monarchy consisted of Slavs and therefore felt that military aid from the Austro-Hungarian Empire was not guaranteed in the event of a war with Russia and France. KEY WORDS: The Balkan War and the Kaiser, German Military Build-Up, German Military Expansion, the German Government and It's Austrian Ally in 1913, Alliance Between Austria and Germany, Germany and Serbia, German Fear of Slavs in 1913, Slavs and the Hapsburg Empire, Slavs and the Austro-Hungarian Empir e.
