100 Useful Tips and Tools to Research the Deep Web By Alisa Miller Experts say that typical search engines like Yahoo! and Google only pick up about 1% of the information available on the Internet. The rest of that information is considered to be hidden in the deep web, also referred to as the invisible web. So how can you find all the rest of this information? Meta-Search Engines Meta-search engines use the resources of many different search engines to gather the most results possible. SurfWax.

iMessage Privacy iMessage is probably one of the most trendy instant messaging systems. Apple presents it as very secure, with high cryptographic standards, including end-to-end encryption preventing even Apple from reading the messages. Is this true? Quick answers What we are not saying: Apple reads your iMessages.What we are saying: Apple can read your iMessages if they choose to, or if they are required to do so by a government order. As Apple claims, there is end-to-end encryption. Also remember that the content of the message is one thing, but the metadata are also sensitive. Now, you can read the article or jump to end of the article where we summarized it. 1. For years now, every time a new instant messaging service has risen, lot of people ask questions about its security.

Multipeer Connectivity As consumer web technologies and enterprises race towards cloud infrastructure, there is a curious and significant counter-movement towards connected devices. In this age of mobile computing, the possibilities of collaboration, whether in work or play, have never been greater. In this age of privacy concerns and mass surveillance, the need for secure, ad hoc communications has never been more prescient. The Multipeer Connectivity APIs, introduced in iOS 7, therefore may well be the most significant for the platform. Multipeer Connectivity is a framework that enables nearby devices to communicate over infrastructure Wi-Fi networks, peer-to-peer Wi-Fi, and Bluetooth personal area networks. Advertising & Discovering The first step in communication is to make peers aware of one another. Advertising makes a service known to other peers, while discovery is the inverse process of the client being made aware of services advertised by other peers.

Voluntary - Bitpost Bitpost private decentralized messaging Source Download 0.9.8.3 for OSX Every love letter, political opinion or personal confession you share with someone using services such as email or Facebook is recorded and can be read by curious employees, malicious government agencies, exposed by hackers or shared with advertisers. We see this as a basic human rights issue and long term potential threat to civil society. That's why we've created this user friendly interface to Bitmessage to help keep personal communications private.

PDF Eraser - Erase and Delete PDF Text, Images or Forms - Download Enabling Communications, Anywhere, Anytime: Arduino Yun as a possible Mesh Extender Platform Regular readers of this blog will know that we have been looking at a variety of hardware options for the Serval Mesh Extender. The Serval Mesh Extender is a device that combines ad-hoc WiFi meshing with long-range license-free UHF packet radio to allow the easy formation of mesh networks spanning useful distances. Typically the UHF packet radio has a range about ten times greater than WiFi. This means that in ordinary suburban and urban areas we get a range of a block or two, and in open rural areas the range can be in the kilometres. We run our award winning Serval Mesh software over the top, providing an easy to use communications system that lets you use your cell phone without cellular coverage, for example, during a disaster, or when you and your friends are near one another outside of the range of your native network. The challenge with the Mesh Extender design is that we haven't had the budget to design our own device from the ground up.
Convert your existing Windows XP system into a virtual machine Run your Windows XP system in Windows 8 with VMware In a recent series of articles culminating with Make USB devices accessible to a Windows XP virtual machine, I showed you how to create a Windows XP virtual machine in Windows 8 using the built-in Client Hyper-V tool. I've received quite a few emails about that series and several people have asked about the possibility of converting their existing Windows XP installation into a virtual machine. I've also had several people ask me about the possibility of running Windows XP from a VHD in a dual-boot configuration similar to the one that I showed you in the article Install Windows 8.1 Preview in a dual-boot configuration using a VHD. Unfortunately, Windows XP was created way before native booting from VHDs was commonplace and as such, the operating system is incapable of booting from from a standalone VHD.
