A few years ago, we bought a digital (data) projector for our classroom. Sure, our school had a projector on a media cart, but to be perfectly honest, it was inconvenient to have to share it with the entire school. (And murder if you had to "wheel" the cart up a flight of stairs.)

We've adopted a balanced literacy approach to explicitly teach decoding and comprehension strategies, and we wanted to use the computer projector pretty much 24/7. So we splurged a thousand bucks and bought our own.

We set up our data projector permanently on a tall filing cabinet. We use the entire side of the classroom wall to project a giant image of the teacher's PC. Pretty much every day, we would use the data projector during our modeled and shared reading lessons, as well as during modeled and shared writing. It was hooked up to the Internet, so we could use it for our media literacy lessons as well.

Pros

* Attention-grabbing. After all, we live in a TV generation. (After some initial training, the novelty wears off and you can use the technology more effectively as a teaching tool.)
* With the right set-up, you can display an image larger than any overhead projector image. Easy to read from anywhere in the classroom. In our class, we aren't projecting onto your typical, pull-down, overhead projector screen. We've covered one side of the room with white paper and created a huge 7' x 10' image.
* Can model how to effectively use technology. (Spell check, effective searching on line, copyright issues) as well as critical thinking skills.
* Easy to integrate multimedia into your lessons.
* Can model comprehension strategies on non-traditional texts (i.e. blogs, wikipedia, website articles, ezines) as well as media texts (i.e. commercials, youtube)
* Easy to display quickly-changing information on the board (i.e. graphing in Math)
* If your school has a scanner (and many photocopiers / printers do have a scanning feature), then it's easy to digitize stuff and throw it on the data projector in the same way that you would throw a photocopied transparency onto the overhead projector.

Cons

* The biggest draw back is that you can't (easily) write on your documents (compared to an overhead projector). Sure you may be able to type faster than you can write, but there are some things that are better done by handwriting (i.e. revising or editing a piece of shared-writing.) Digital ink can be tricky or expensive.
* Technical difficulties - technology doesn't always work. Computers crash, hardware fails, bulbs burn-out... all when you least expect it.
* Expensive. Although the price of projectors are continually dropping, you'll still have to shell out $500 to $1000 for a decent, new data projector.
* Security. We've locked our projector to the desk to prevent theft, but that doesn't mean things can't go wrong. Will you lock it up at night? Take it home on the weekends? Where do you put it when you have a supply teacher covering your class?
* Insurance and Replacement Cost: Chances are your personal items aren't covered under the school's insurance plan and won't be replaced if anything happens. Better call your home insurance provider to see if your belongings are protected at work.

Well, if you are new to fact that Cisco routers can communicate with Radius servers; then that most likely means, you are new to the Cisco IOS "Global" configuration command called "aaa new-model".

Network administrators (like you) use the "aaa new-model" command to enable the Authentication, Authorization, and Accounting (AAA) access control model on a Cisco router. In other words, the "aaa new-model" command is used to "Globally" enable a Cisco router for Authentication, Authorization, and Accounting or AAA.

Below is an example of using the command:

Example:

Router>enable

Router#configure terminal

Router(config)#aaa new-model

Router(config)#end

Router#

As you can see, it's a very simple command to use; because it doesn't require the use of arguments or keywords.

Now, let's say you've already used the "aaa new-model" command to enable Authentication, Authorization, and Accounting (AAA) on a Cisco router and now you want to disable it; well, to perform that task, all you need to do is type the word "no" in front of the command like you see below.

Syntax: Router(config)#no aaa new-model

And, just in case if you were wondering, Cisco routers by default are not enabled for Authentication, Authorization, and Accounting (AAA), you have to enable them.

I hope this article was very informative and helped you quickly understand the usage of the "aaa new-model"command. If you need to learn more about the command; I suggest you visit my website, were you'll find the latest information regarding Cisco IPv6 Design and Implementation Techniques.

Registry tools help you repair corrupt registry entries that help you resolve several errors. Most of the time, these frequent errors, freezes, and crashes force you to seek external technical help to restore your PC back to a healthy state. Repairing the registry all by yourself is a suicide mission of course, not you. In fact, even if you were a computer tips technician, it would still be next to impossible to prevent all registry errors from occurring. Every time you give a command, the registry is where it heads to complete the assigned tasks. The registry is where all the crucial information is stored. You should also note that the more heat the CPU generates, the slower it will likely respond. This increased temperature causes it to behave erratically, resulting in very slow reaction time. Checking Out Your Hardware There are many reasons why a computer may become sluggish and unresponsive.

If another person obtains the PC, they can access anything that the previous owner had on it if the hard drive is not erased. It is a good idea to erase the entire hard drive before disposing of it.

Here are some technology things that you could do with your students. Not everything may be feasible (i.e. cost factors) or appropriate (i.e. security or privacy issues):

* some of the things we're already doing,
* some of the things we're thinking of doing, and,
* some of the things are simply wishful thinking, but great ideas have to start somewhere...

How do you integrate technology into the curriculum? Do you have any ideas to add to the list?

Class Set of Laptops

* Get a company to donate a class set of laptops when they upgrade their equipment. (The company can receive a charitable donation tax-credit.)
* Set up a wi-fi hotspot in your classroom so that students can blog online during independent reading and writing workshops.
* Purchase digital copies of textbooks to have a paperless classroom. Use text-reading software (i.e. Kurzweil) to highlight and take notes in the textbook.

Non-Traditional Reading and Writing

* Teach students the differences between formal, informal, and colloquial language and explore text messaging, chat rooms, and msn-speak as forms of colloquial language.
* Evaluate the evolving nature of language and develop word-attack skills by examining how words get accepted into everyday language (or the dictionary). For example, Google is now a commonly used noun and verb.
* Use text-reading software (i.e. Kurzweil) to allow students to access difficult texts.

Blogging

* Have students set up personal blogs as a medium to publish their writing portfolios.
* Explore how Google is a popularity contest. Publish work in an e-zine article directory to understand how to build inbound links. Post comments on other blogs to build inbound links.
* Explore copyright issues. Publish work in a blog or an e-zine article directory will inevitably end up with your work scraped onto another blog without proper attribution. Explore how that feels and the ethics of using other people's content without consent.

Computer Safety

* Discuss cyber-bullying: ways to protect yourself, how to respond when it happens, and how to avoid accidentally cyber-bullying when blogging.
* Explore computer safety: password strength, viruses, trojans, phishing, etc.
* Learn about online dangers and ways to protect yourself.

Classroom Website

* Make hand-outs and homework assignments accessible on a classroom website.
* Use a secure website as a communication tool for marks for both parents and students.
* Introduce your students to HTML and web design.

Making Money Online

* Introduce students to the business of making money online.
* Explore advertising online - how it works.
* Fund raise by selling stuff on e-bay.

GPS and Mapping Technology

* Geo-cache with your students.
* Use GPS technology or mapping software (i.e. Google Earth) in math class to construct larger geometric shapes. (i.e. construct a circle that has a radius of 5 city blocks.)
* Apply GPS technology or mapping software in Geography.

The Internet as a Global Village / Community

* Find a class to pen-pal with and correspond using blogs, email, or IRC chat rooms.
* Use a wiki for students to synthesize and evaluate knowledge gained in a content-subject like History or Geography. They can track how their understanding of concepts grow. Demonstrate how our understanding of a subject-specific topic evolves over time (i.e. a dynamic and digital KWL chart)
* Publish student work in English and in their first language online so that relatives overseas can celebrate in their success.

Technology as a Teaching Tool

* Use a data-projector in class to do modeled and shared readings.
* Use a data-projector in class to do shared writing: the modern equivalent of flip-chart paper
* Use dynamic geometry software (i.e. Geometer's Sketchpad) to explore math concepts.

Music and Technology

* Buy songs (i.e. itunes) and allow students to DJ their own school dances.
* Critically examine popular music to determine whether mainstream music is appropriate at a school dance (i.e. Soulja Boy - Crank that)
* Create your own pod-casts. Students can use free sound-editing software (i.e. audacity) to mix in free sound effects (i.e. ljudo.com) with their digital recordings of their voices.

Class Projects

* Send an object around the world and invite people who find the object to leave a message online in the classroom blog.
* Explore the video making process: scripts, recording, editing, post-production
* Explore youtube as a medium to publish content.

Well, in the past few years, a majority of network administrators (like you) have become more security conscious and are responsible for making sure their entire network is totally secure from hackers, virus, worms trojans and things of that nature.

Now just in case if you didn't know, by default once you assign an IPv6 address to a Cisco router's interface; that router is then automatically capable of being reached by using the Hyper Text Transfer Protocol or HTTP.

So, if you don't want a particular Cisco IPv6 router to have the capability of being reached via HTTP, you'll have to disable http access to the router; by performing the following steps on the router:

Steps:

Router>enable
Router#configure terminal
Router(config)#no ip http server
Router(config)#exit
Router#copy run start

Steps explained

Step #1

1. Router>enable

Puts router into Privileged EXEC mode.

Step #2

2. Router#configure terminal

Puts router into Global configuration mode.

Step #3

3. Router(config)#no ip http server

Disables HTTP access to the router.

Step #4

4. Router(config)#exit

Causes router to exit global configuration mode and re-enters into Privileged EXEC mode.

Step #5

5. Router#copy run start

Saves the contents of the running-config to local Non -Volatile Random Access Memory (NVRAM).

I hope this article was very informative and served its purpose; to help you quickly understand how to disable HTTP access on a Cisco ipv6 router. I invite you to visit my website were you'll find the latest information regarding Cisco IPv6 Design and Implementation Techniques.

There is nothing more annoying then going to your computer in the morning...turning it on...then waiting FOREVER for it to startup. I bought a new computer running windows vista not to long ago and at the time it was a fast machine. Then over time it developed a slow vista startup until it finally got to the point that I could go eat breakfast and wash a load of cloths before it finally started up. When you live a hectic life and your always strapped for time then this is a serious problem.

The most common culprit behind a slow vista startup is the computers registry. Most people don't know the importance of the registry on their computer. The registry on a vista computer is comprised of keys and functions. Think of this as a library for your computer. The keys are like the index numbers on a book and the functions are like the books themselves. Now imagine that a libraries index system was not categorized properly. It becomes a lot more difficult to find what you are looking for. This is also the same for a computer. When the registry becomes corrupt the computer cant easily find the functions it needs to start up thus making it work a lot harder just to startup. This is what leads to your slow startup. Vista computers are notorious for this problem as their registry is highly sensitive.

Everyday actions such as installing new software or downloading anything from the Internet can cause your registry to become jumbled. It is almost impossible to avoid doing something to your registry every single day, so you need to be constantly repairing it to keep it up to par. However you can not repair the registry manually unless you are trained to do so and even most pros use a program to automate the process. So you will need a program if you intend on keeping your computer running smooth and keep it from having a slow vista startup.

There are several other tips and tricks you can use to help get rid of a slow vista startup but none of these are near as powerful as cleaning your registry and will not deliver the drastic results that the before mentioned method will. You should clean your registry before trying any other methods of speeding up your startup in vista. However if you do clean your registry and then try the other methods as well, then your computer will probably run even faster than when you first bought it! That is what happened to me.

Everyone wants faster Internet access these days, not everyone can afford the expensive costs of Internet on T1 connections so most people are forced to opt from services from other subscribers and make use of a variety of tools and services such as the Internet Speed Accelerator tools that seem to be available today. A variety of tools and services are available for use and these tools and services perform the required task by taking advantage of a series of technologies and services in order to boost the speed of your existing Internet connection to something which you would find much more appealing.

These products are moderately expensive and one technology that some of these tools use to boost your Internet connection speeds is by boosting a number of settings which might be related to TCP/IP technology which is the main technology that guides the transmission as well as delivery of the information over the Internet. By boosting these settings such Internet Speed Accelerator tools ensure that you receive and process your data at a much faster rate than usual, allowing you to take advantage of a whole lot of opportunities which fast Internet access tends to open you up to.

Sometimes the speed of your Internet access is not hampered so much by external hardware but internal hardware as well such as your computers memory. A number of solutions will also provide additional assistance by boosting your computer memory and helping your computer run a whole lot faster. This solutions works with a variety of Internet access technologies because it’s working on your computer and not the external connection that you rely on in order to access the Internet. By doing this it keeps everything faster on a local level while giving you the chance to use the Internet connection you pay for better.

Desktop settings can help your computer run much more faster than you expect, some of them also make use of a number of online tools and services in order to boost your connection such as the channeling of all your data through high-speed VPN proxies which are connected to T1 or devices greater than T1 speeds on the Internet. Most of these solutions are more or less reasonably priced which allows you to make use of fast internet at rates much lower than what would be obtained elsewhere. Some of these tools require you pay a monthly fee while others require that you pay a one-off subscription in order to enjoy their services and further your benefits.

Some tools even do much more than speeding up your regular Internet connection, some of these tools go the extra mail by helping you speed up your e-mail connection as well. E-mail is just as important as regular Internet; after all it is the preferred means of Internet person-to-person communication so you can easily make use of Internet Speed Accelerator tools that provide you with this opportunity as well and allow you to do whatever it is that you do on the Internet with maximum proficiency and profitability.

It can be easily said today that you can live a normal life in front of a computer with internet connection. You can communicate with people, buy almost everything from online stores and actually get a job that you can work from home through internet. We can safely say that the internet today is growing into a parallel world kind of deal. In the World Wide Web, we see many things that are alike to our life in the off-line world. There are communities of people, auction houses, stores, and companies that are made directly for the on-line world which eventually affects both on and off line world.

In online communities, you are given an account to represent yourself and to befriend others by linking yourself with other accounts. People write posts and upload pictures to express themselves and communicate with others like the off-line community. You can go visit auction house websites such as ebay or go to an online store website such as amazon and shop in front of your desk. You can even book and plan a whole trip from an online website. Though it seems like the internet is convenient with methods to do everything on it, some people say it is hard for others who doesn't know the website address and ultimately, it would be useless since there are not that many ways to advertise online websites to others, but I say otherwise.

Like the off-line community, people from the online community send links for websites of online stores, websites, and companies that they really like and discuss about them. How their product or programs were really helpful and how the other was more convenient, kind of like those talks over coffee table of how they got a better deal on a certain product than the other guy and thus advertising for their company. There are banners of advertisement on major websites like the billboards on the major freeways we ride on. There are online marketing websites that does directory advertising, and optimize some search engines so that it is easier to search for a certain product or a website through a search engine.

There are many other ways to advertise a website; Brochures and TV/radio commercials with website addresses for people to go to, website addresses on the box of the product to find more information, website address on a movie poster, on a T-shirt, and some people even use spam emails to advertise online. There are countless ways to advertise your online store, both on and offline. Many different ways of advertising are being developed everyday by the people who realize the power of online marketing. As internet is growing into a parallel world, it is becoming more like our world in a sense that it is being used as another method of making money. It is being too commercialized. Though it is a unique medium, like the TV, where both entertainment and commercialization co-exist, we should take caution while utilizing this medium.
