Internet Security Versus Social Media, First Amendment Rights and Hackers


By 


Social media, First Amendment and data security issues are interwoven in recent accounts of current events that raise fascinating concerns and questions.
In San Francisco, attempts were made to foil protesters planning to disrupt public transportation services when the Bay Area Rapid Transit authority temporarily interrupted cell service at several subway platforms. This unleashed a barrage of reaction and debate on both sides of the issue. Perhaps the most notable and certainly the most vicious group to take exception to BART's action was the hacker group Anonymous, which attacked myBart.org, defacing the site and releasing personal information for 2,400 BART riders, and even organizing a subsequent demonstration.
It's not only the vigilante group that is acting in the wake of BART's decision to thwart protesters by disrupting cell service, however; the Federal Communications Council has also launched an investigation into the matter.
Was BART's temporary shutdown reasonable given the public safety concerns of the transit authority, which designates free speech areas for public protests safely outside of its train and subway platforms? Were the free speech rights of the protesters violated? What about other riders who may have tried to reach a child, parent or even emergency services during the period cell service was disrupted? Was it worth the cost to attempt to prevent potentially dangerous protests?
While all these issues are sorted out, BART's professional reputation has certainly been damaged. Policy-makers are questioning the organization's decision-making and lack of leadership, some even comparing BART to former Egyptian leader Hosni Mubarak, who shut down cell service in Tahrir Square in response to peaceful protests earlier this year.
Days before the San Francisco incident, social media was cast first as the villain and then as the hero across the pond in London. First, rioters utilized BlackBerry Messenger to organize days of extremely destructive and disturbing lawless acts. In the wake of the riots, however, volunteers have been recruited and massive cleanup efforts have been mobilized via Twitter and Facebook, redeeming social media's role in this unfortunate episode in the eyes of Londoners and other observers.
Back in California, Anonymous is again making threats, this time in Fullerton where the vigilante organization seeks retaliation for the alleged beating death of a homeless schizophrenic man by Fullerton police. The Anonymous YouTube video is both fascinating and disturbing with its masked spokesperson, computer-modulated voice and demands.
So where will this tale end? Its conclusion is yet to be written. The debates surrounding the use of social media platforms to incite action, the use of cyber-attacks to exact vigilante justice and the threats to First Amendment rights and data security are too important, however, for any of us to ignore. Where do you stand on these issues? Which of these threats do you find most disturbing?

Wi-Fi VS 3G, What to Choose?


By 

Staying connected to the Internet on a vacation or while traveling has become easy. Thanks to the development of new technologies. There are public wireless hotspots now, internet on the mobile and even the possibility of using our cell phone as a modem, which make it easier for us access the internet on the go. It is important for us to be able to browse the internet for various reasons; we need to check our mails, both personal and professional, stay in touch with friends and family and even for the purpose of entertainment, like watching video clips online or playing games through various websites, internet is required. In fact, a lot of us are addicted to the World Wide Web and cannot do without it because of which we appreciate the available technologies that enable us being online all the time. However, a question arises when it comes to choosing the best technology for better connectivity, i.e. Wi-Fi vs 3G. Let's try to understand both these technologies to come to a conclusion.
What is Wi-Fi?
It stands for Wireless Fidelity which is a technology used to link and transfer data wirelessly between devices. It is widely used for connecting devices to the internet, like connecting a laptop to a modem without any wires. In terms of mobile communication, wireless hotspots are present in most places these days from where people can connect their cell phones to the internet. This service may or may not be free all the time. These hotspots have towers or receivers which transmit frequencies and signals wirelessly to different electronic devices. There are millions of people worldwide who use this technology.
What is 3G?
It stands for 3rd Generation Mobile Telecommunications and is an upgrade from 2G or GPRS. It is a modern technology through which faster mobile connectivity is obtained by applying higher frequencies and faster transmission rate. Using this technology people can acquire speed up to 144 Kbps per second. Many companies around the world have started providing this technology to people through mobile networks.
Wi-Fi vs 3G
3G is better than Wi-Fi due to the following reasons:
1) It is very fast and can be connected from anywhere.
2) No transmission tower required.
3) Best for video streaming and playing games.
However, 3G is more expensive so the verdict of Wi-Fi vs 3G lies with the people depending on what they want, whether they want a faster service or a more economical service.

Information About 3G And 4G Technologies


By 

We live in a fast changing world where new technologies emerge every now and then. Speed is of great concern to people in the 21st century and so scientists and engineers are constantly trying to explore new ways of faster information transmission, the information being either voice or data. This effort resulted in inventions of technologies like 2G, GPRS, Wi-Fi, Broadband, T1 etc. Also, the usage of mobile phones has changed, people no longer view a cell phone as a device meant for only talking or texting and it is rather expected to provide access to internet and other application that one would find in a PC. Activities like video streaming, watching movies and playing online games on the cell phone are very popular which make companies to invest in their R & D and come with networks that can better support these demands of the consumers. This is why 3G and 4G were introduced in the mobile communications market. They were introduced only in 2010 and in fact, many countries are yet to accept them. Thus, in 3G vs 4G, which one is better, is something we will find out in due course.
What does 3G stand for?
3G is the short form for 3rd Generation Mobile Telecommunications. It is a wireless communication technology that was developed to enable faster transmission of information. It's expected to provide consistent speed of at least 144 kb per seconds. Some of the features associated with it are live video streaming, better quality video calls, faster internet connectivity etc. It has been popular so far in most of the countries like US, Japan, China and India, and in the US, various tests have observed that it is able to deliver the kind of services that were promised by the mobile operators, when it was introduced. It was first introduced in Japan by NTT Docomo and then Verizon brought it to the US market in 2010.
What is 4G?
There is actually no official definition of 4G; few companies claim to provide faster and better network than existing ones, however officially they are just upgraded versions of 3G. Those claiming to be 4G networks will have to pass the test of time and prove that they are able to deliver what they are claiming; only then their authenticity will be verified.
3G vs 4G
It is too early to give a verdict on 3G vs 4G as they are both very new. Once we are aware of all the positives and the short comings then we will be able to compare these two.

How to Use Calling Cards Without Getting Your Wires Crossed


By 

A famous phone company once said that long distance was the next best thing to being there in person. Back in the old days, bigger phone companies charged high rates for long distance calling. Nowadays there are many low-cost options for long distance calls, even internationally.
Even for cell phone owners, many of those carriers have calling plans or minute plans that make it low-cost for long distance calls in your own country, and some do have international plans that offer those calls at low charges per minute. However, there might be a less expensive method than this.
THE USE OF CALLING CARDS The answer is to use a phone card. And the ones available for you buy online usually offer cheaper rates than other calling cards you can buy in almost all countries at supermarkets, pharmacies, convenience and many other stores.
Usually the quickest and least expensive answer is to get a calling card from an online vendor at a website meant for the purchase of calling cards. These websites often offer cards that have plans to call certain countries at very low rates. These rates are often cheaper than what any carriers offer, and are often cheaper than any other calling cards.
Now one must shop carefully at the various websites. A few hints about buying them online and using them. Keep in mind that not all cards sold online or in stores offer local access numbers in your calling area. Thankfully you can check before buying to see if the card has a local access number in your area. This is important so that you don't incur long distance charges just to use the access number. Chances are good they will have an access number close to you or in your city if you live in a larger city or metro area.
Now, there are many different cards to choose from when calling. You should keep in mind the purpose of your calls, the need for quality in the connection and so on. Generally the least expensive cards charge a small fee to connect the call then a low minute rate. These cards are better for calling friends or family if you will be on the phone for a longer period of time per call. If you think you will be making smaller duration calls and more of them, such as in business, and do not want to pay a connection fee then you will probably pay more per minute. Also as is usual for most things the more you pay per minute the better the quality. Since they will email you the code to use the card right in your email, you won't have to leave home to get a calling card when purchasing online.
