Solar Plant for a better life

Solar Plant is "Plants" that can change sunlight into electricity. Actually this device is the development of the existing solar technology into a more portable format. Limited charging shaped vase is capable of converting sunlight into electrical energy with the concept of photosynthesis. By combining the principles of nature and technology, maybe in the future we will change the world a better place than today.

Photosynthesis is done by using solar panels mounted on top as the energy collector and converted into electrical energy consumed ganget enough for you, quite simple and very friendly environment. Imagine if millions of people who use gadgets to switch to this technology, not how much renewable energy can be saved.

   The risk of using WIFI connection    

The most effective method to prevent interception of data via Wi-Fi is to use a VPN. However, VPN is too complicated because at present there is no solution to the VPN plug-and-play. For modern society, technology, Wi-Fi (Wireless-Fidelity) is a part of everyday life. In the big cities in Indonesia, Wi-Fi not only penetrated the office. But also shopping centers, restaurants, coffee shops, hotels, campuses, and even housing-housing. The main function is Wi-Fi wireless internet access.

In public places, there is Wi-Fi that are served free of charge and some are paid. In public places also, for example in shopping centers, plenty of options usually available access point. Access points were visible when the notebook users have to select the SSID (Service Set Identifier), the alias name you want to use the wireless network. When a notebook is connected with a particular SSID, the notebook that was already entered into a Wi-Fi network.
Malware Analyst, Kaspersky Lab warns Christian Funk, notebook users should be vigilant when accessing Wi-Fi in public places. Because, Funk asserted, access the Internet through Wi-Fi network extremely vulnerable to attack in the form of data piracy. To trap the victim, criminals generally create a wireless access point (hotspot) for free or copy the login page of the Wi-Fi service provider trusted. Furthermore, criminals are just waiting for the victim lured into dangerous networks.
"To perform this attack, the perpetrator does not need to have technical knowledge of high-end computing. Actors only need to create a fake access point in order to trap the victim. Once the victim is trapped, then the players can tap into typed data that the victim in the web pages opened via Wi-Fi , "said Funk.
Funk explained that the main target of this attack is to steal credit card information on the victim when the victim make transactions online using the Wi-Fi. However, criminals also steal information such as e-mail accounts as well as their passwords, as well as the accounts used by victims to access Internet sites, such as social networking sites.
Funk warned, data theft has serious consequences. For example, if criminals could steal credit card information of victims, the criminals could take advantage of the victims credit card for shopping. Spending bill that also fell into the victim. Though the victim have never committed expenditure.
Another example, if criminals are able to steal account and password of your e-mail the victim, the criminals can take advantage of e-mails offering to spread spam (unsolicited e-mail address.) These crimes can be done if the criminals could steal another account, such as accounts of social networking sites.
Funk emphasized that the most effective method to prevent piracy of data via Wi-Fi network is to use a VPN (Virtual Private Network). With VPN, the data from the notebook users are sent to the server through a virtual tunnel, and vice versa. As a result, the data can not intercepted. However, Funk admits, VPN technology is too complicated for most notebook users.

"Encryption of wireless data traffic is too complicated for users. At this time there has been no VPN solution that is plug-and-play (can be used without the need setting)," said Funk.

Without VPN, Wi-Fi users should not conduct financial transactions or access the internet banking. Also, users should be diligent, industrious change the password of the accounts owned. If you must conduct internet banking transactions in a mobile, Funk suggested, notebook users should use the 3G internet network.

"3G Internet becomes an attractive alternative because of the Wi-Fi and 3G data traffic is more difficult to plow. Also, 3G Internet network has wider coverage than Wi-Fi. speed 3G internet is also more than enough for most purposes mobile computing," said Funk .
