Surfing The Web Anonymously

When you surf the web it is possible to learn information about you even when you don't want to advertise who you are. This is true even if your system contains no virus or malware software. Specifically information that is easily available online includes your IP address, your country (and often more location information based on IP address), what computer system you are on, what browser you use, your browser history, and other information. It gets worse. People can get your computer's name and even find out your name if your machine supports programs like finger or identd. Also, cookies can track your habits as you move from machine to machine.

How do people get this basic information about you?

When you visit another web site, information about you can be retrieved. Basically, information is intercepted and used by others to track your Internet activities.

How do you stop this from happening?

First of all, it is possible to serf the web anonymously and thereby stop leaving a trail for others to find. Note that this is not fool-proof, but it makes it much harder for people to know who you are. There are products called anonymous proxy servers that help protect you. The anonymous proxy server replaces your Internet address for its own. This has the effect of hiding your IP address and making it much harder for people to track you.

How do I get an anonymous proxy server?

There are many vendors who sell anonymous proxy servers. There are also free proxy servers available to you. Two such products are ShadowSurf and Guardster. Guardster (http://www.guardster.com/) offers various services for anonymous and secure access to the web, some paid as well as a free service. ShadowSurf (http://www.shadowsurf.com/) ShadowSurf provides anonymous surfing at their site for free. Go to it and you will find a box to enter a URL that you want no one to track. There are many others, but here are two that are frequently used.

Another interesting product, given the recent news about the Google search engine filtering its findings for the Chinese government, is Anonymizer (http://www.anonymizer.com). This company, among others, recently (Feb 1st, 2006) pressed that it "is developing a new anti-censorship solution that will enable Chinese citizens to safely access the entire Internet filter-free" (http://www.anonymizer.com/consumer/media/press_releases/02012006.html).

Does an anonymous proxy server make you 100% safe?

No. Still, you are much better off if you use such technology.

What other things should I be concerned about when trying to keep my private information private?

Three other items come to mind when trying to keep your information private. First, you can use an encrypted connection to hide your surfing. This article does not go into detail on this, but search the web and you will find a lot of information on this. Secondly, delete cookies after each session. Third, you can configure your browser to remove JavaScript, Java, and active content. This actually leads to limitations, so you need to think about the cost/benefit of this course of action.

Anything else?

Wishing you happy and safe surfing!

Website Security Rules of the Road

In 2004, online consumer spending was at a record $65.1 billion. More and more people are attracted to the ease of online shopping and are spending higher amounts. Unfortunately, the chances of becoming a victim of Internet fraud are also increasing. The Internet National Fraud Center Watch reported that the average loss to fraud victims for just the first six months of 2005 was $2,579. This is compared to the $895 average for all of 2004. Complaints relating to general merchandise purchases (goods never received or misrepresented) accounted for 30% of Internet fraud complaints, and auction purchases (goods never received or misrepresented) topped the list at 44%.

While many e-commerce Websites are reputable and have taken the necessary safety precautions to protect you, it never hurts to always proceed cautiously. If you are making an online purchase consider these easy steps:

1. Use only one credit card, preferably with a low credit limit, when making online purchases. Avoid using an ATM or debit card.
2. Be wary of unsolicited offers by sellers. The Internet National Fraud Information Center Watch reported that email, as a method of contact by Internet scammers was up 22% in 2004.While the offer may be legitimate, spammers like to use this tactic to side-step reputable sites that provide consumer protection for online purchases.
3. Use only reputable e-commerce websites that list a street address and telephone number in case you need to contact them directly.
4. Read the website’s privacy policy. Some websites may reserve the right to sell/give your information to a third party. Check the document to see if they allow an opportunity to “opt-out” of receiving special offers from third-party vendors or for permission to share your personal information.
5. Check for a lock symbol in the status bar at the bottom of your Web browser window. Also, do not provide your personal information if the website address doesn’t start with “https” (a sign that the site is using a secure server).
6. Choose only verified sellers. Check to see if the vendor is a verified member of a reputable third party such as the Better Business Bureau, VeriSign, or Guardian eCommerce. These third-party sites help to ensure online consumers will be protected when shopping or conducting e-commerce transactions.
7. Check that the delivery date posted is reasonable. If you have not dealt with the vendor on a regular basis, be wary of any Website that states the shipment will be delayed 20 or more days. Delivery dates of 7-10 days are more common.
8. Keep a paper trail of all online transactions. Print out a hard copy of the transaction and keep it in a file for future reference.
9. Be wary of website offers that just sound too good to be true. The Internet is littered with get rich quick scams and false advertising claims. Investigate all claims thoroughly before proceeding.
10. If you do not receive what you paid for, and the vendor will not return your emails or calls, contact your state’s Department of Consumer Affairs for further assistance.

Can someone tell me what VoIP is?

Without going into any technical terms I will explain to you what VoIP is and how you can benefit from it. I answer your questions and at the end of this article you will fully understand why you ought to have it.

Once you understand about what VoIP is you will be really keen to use it.

The first and very last bit of a hint of technical terms is what the letters VoIP mean. It means Voice over Internet Protocol. Wow, now we have got over that we can talk about just what it is all about. Basically, all this means is that, instead of your voice being sent down a line in the old way down landlines, it is now being sent down an internet connection.

There are a couple of differences between these but basically the internet way is very fast and you voice is sent in little data packages which is converted back to your voice at the other end. The old way was slow so not as economical cost wise. Hence, although you may not have realised it your phone companies have been converting your voice messages to VoIP for some time now. They can handle thousands of conversations at the same time down the same line whereas previously they could not. However, they have been reluctant to reduce prices until the pressure has been put on them recently by new VoIP companies springing up.

So… There we have it. VoIP is just anther way to have a conversation between two or more people. How hard is that to understand?

Now we come to the bit where you have a choice. Do you stick to paying a high price to phone all over the world or do you look for someone to use that will give the same – if not better service much cheaper. I know what I do!

This is where most people start to panic asking the questions – How do you do it? With whom do you do it? Do I need to have some special phone line? Do I need a special telephone? It's still a mystery to me, who will help me? And so it goes on. Yes, all these and many more questions are quite understandable. These changes are very new and like anything new, we fear the unknown until we get some of the answers.

So let us tackle some of the questions here and you will see that there is really nothing over complicated at all. After all, at the end of the day you are going to save a lot of your money. Afford to be more in contact with your friends without worrying how much the call is going to cost you.

I have written a lot of published articles that are reproduced around the world so I can give you the guidance that you may need. Let's find the answers to some of those questions.

How do you do it? First you need to decide on a VoIP service to go with. There are a lot around, some based on original VoIP platforms and have developed an impressive array of web facilities. Such a Skype, Verizon and other well known's. But there are a number of new VoIP service providers that are pushing forward the VoIP technology. These are patenting these new platforms /features. Check my resource at the end.

With whom do you do it? Sounds the same as the first question; however what you want is someone to guide you in both your choice and in understanding how to use the VoIP features. Better a service that provides you with a personal helper.

Do I need to have some special phone line? No. You will be using just your normal cell phone or telephone line.

Do I need a special telephone? No. Not necessarily so unless you wish to have an I P telephone. This all depends on how far you want to go in ease of use. Alternatively to are able to use an adapter to which you plug in your normal phone. However, the service can be used without special setup, using your ordinary landline, computer, or a cell phone. You do not even have to have a connection to the internet with companies such as Global1touch. You simply dial a special number, disconnect. You will get a call back asking which number you wish to call. You enter it and you are connected via VoIP. There is no cost involved with your normal landline or cell phone service provider. In fact on a cell phone you will not even lose any ‘free' time minutes.

It's still a mystery to me? Well I hope that you now see that it is not really something beyond anyone to use. Now if you had a person to assist you, you would find your worries disipate. Did you know that VoIP customers worldwide are doubling year on year, so it cannot be that hard.

I recommend VoIP to all and particularly to families where a huge saving can be made. Small to medium business are taking up VoIP rapidly, realising the massive savings they can make, plus now that VoIP communications are becoming mobile and no longer chaining you to a computer it is even more appealing. Contacting personnel via cell phones locally and internationally runs up large communication accounts, sometimes on top of actual cell phone package deals. Using VoIP slashes the costs dramatically.

I am convinced that now you have read this article you will feel more comfortable in considering bringing onboard VoIP in your communications as a package.

4 Things You Need To Know Before You Switch To VOIP Services

VOIP Service for making and receiving phone calls is probably the most cost effective way to communicate, and is showing the phone companies that their "cash cow" of home telephone service may be coming to an end on the horizon. Still, VOIP service is not for everyone, and here are some things that you need to verify and feel good about before you consider switching to VOIP service.

1. Your High-Speed Internet Connection is critical.

Almost any VOIP service that you choose is not going to include high-speed Internet service. The VOIP provider assumes you already have that, and would have that whether you decided to implement VOIP or not, which is probably true in most cases.

However, what the VOIP service provider does not tell you is that your high-speed Internet connection needs to be fast, stable, and reliable. Depending on where you are and what high-speed Internet provider you have chosen, this may not be a given. The VOIP provider has ZERO control over this – if you have a lousy Internet connection, VOIP will be lousy, it is a one-to-one relationship.

There are various online sites that allow you to do a speed test on your connection so you can get a feel for how fast it is. The problem is that these tests do not tell the whole story – it might have been fast at the moment you did the test, but is slower than molasses an hour later. Do you notice it stopping when you are using it or having significant time delays? This could be a sign that VOIP will not work well on it.

Also, do people in your household also use the computer when you would be talking on your VOIP phone? If so, your connection may not be capable of handling both connections at the same time. Typically this is more of a problem for DSL than for cable, but it can represent a problem with a cable connection as well.

Is your only option a satellite high-speed Internet connection? Forget it. You are not going to be happy with the results of VOIP service on a satellite connection.

2. When your high-speed Internet connection goes out, so does your phone

Despite the fact that they have over-charged us for years, you need to give the telephone company credit, since when you pick up the phone, you almost always can hear the comforting sound of a dial tone, ready to make your call.

With a VOIP phone, you are depending on your Internet connection to make and receive phone calls. If your high-speed service goes down, then your ability to use your VOIP phone also goes down until the internet service comes back up. This again goes back to the reliability of your high-speed Internet connection and provider.

3. Be sure 911 is supported

All VOIP providers are supposed to be setup so that they support 911 (or E-911) services in case of emergency. You see, with a traditional phone line, if you call 911, they can tell where you are calling from. But this same ability does not exist with a VOIP phone, so you need to register your VOIP phone with the service so that if you call 911 from your VOIP phone, the emergency responders will know where to go.

4. Be ready to save money and have tremendous flexibility.

There is no doubt about it, VOIP service is significantly cheaper than traditional phones from the phone company. At no extra charge, you typically get the features you would pay the phone company extra for, like caller ID, call waiting, voice mail, and call blocking. You also typically get unlimited or high-usage local and long distance calling throughout the country at no additional cost with VOIP.

If you travel, you can take your VOIP phone with you. If you are traveling to visit your friends in Denver or cousin in New York, just plug your VOIP phone into their high-speed modem and you can continue to make and receive calls just as if you were at home, using your same phone number. If you are in a hotel in Chicago, again plug your VOIP phone into the high-speed connection in your hotel room, and you are making and receiving phone calls as if you were at home.

What's Up With Wikipedia

Wikipedia - The biggest free-content encyclopedia on the internet and one of the top 100 websites in the world. It is also the most popular example of a Wiki (How Wikis Work). This unique online encyclopedia allows users to log on and become contributors. As a result many articles are written by the foremost experts in a field with lots of current information. Unfortunately, some articles are also poorly written and may contain incorrect information. This has led to several controversies.

The website has often been criticized for inaccuracies by educators (some examples here). Even the co-founder of the website, Larry Sanger has publicly stated that: "While Wikipedia is still quite useful and an amazing phenomenon, I have come to the view that it is also broken beyond repair." Here is a link to Wikipedia's response to the question of:

No mater how you feel about it, there are some good uses for a site like Wikipedia. For example, one good use for Wikipedia is researching the most recent developments in technology. Because of the way it is edited it can be quickly updated with the most recent information about technological developments long before more traditional reference sources can even start to make updates. It can also be useful in pointing a researcher towards more reliable sources of information. Most Wikipedia entries include several links to outside websites that contain additional information for example. One also has to admit that the site is well laid out, easy to use and has a pretty efficient search engine. At the very least educators should become familiar with it just as they should become familiar with any web phenomenon that effects their students' learning.

A few years ago there was a research study that compared Wikipedia to Britannica for accuracy. The study, which was published in December of 2005, showed Wikipedia to be more accurate that Britannica. You can read about the results here:

cnet.com: http://news.com.com/2100-1038_3-5997332.html
wired.com: http://www.wired.com/culture/lifestyle/news/2005/12/69844

In a more recent development the co-founder of Wikipedia has founded a new website called Citizendium where he hopes to improve on the Wikipedia model by adding "gentle expert oversight" and requiring contributors to use their real names.

New Time-Saving Technology Is About To Revolutionize Your Life

While it may seem nothing much changes, a lot is changing, and often right under our noses. Time-saving technology is always at work to help us complete tasks at home and on the job even faster than ever.

When we save time doing a task that used to take us longer, we suddenly have more time to do that task even better or switch our attention to an entirely different task.

Just think how you did business a few years ago. Instead of answering email, you probably spent much of your day talking on the phone. Now clients organize their ideas more efficiently to contact you with convenient email. You still spend time working with clients, but I'll bet it's not nearly as much as you spent in the "telephone only" days of the early 1990s.

Think about how technology has changed life in the home. Eighty years ago people didn't have all the high power vacuum cleaners we have today. Homes were a lot dirtier than they are now (despite how Grandma may remember them:-). When vacuum cleaners became affordable and a feature of every home, people started doing a lot more housework. Believe it or not, historians tell us the average homemaker spends far more time cleaning than she/he did 80 years ago.

That's why I'm so excited about the new lines of "robot" technologies we're starting to see. Actually, this technology has been lurking in the wings for years, but has only recently become advanced enough to operate trouble-free at an affordable cost.

Robot vacuum cleaners can now automatically clean your home, working all day and all night if needed. They don't complain and never need to be paid. Furniture, kid's toys, and pets don't confound them, they just go around.

Equally exciting are new developments in robotic lawn mowers. If you're one of millions of Americans who own a large yard or endure uncomfortably hot summers, you'll immediately see the value of this technology. A Robotic lawn mower can cut your grass with professional quality, handing anything from a small yard to a large five acre estate. Reliability, energy efficiency, and overall convenience have all improved, making this a time-saving technology whose time has come.

Take the long look at technology in your life. Realize that time-savers let you do your job better and can free up more time to do new activities.
