How to Tell If A Website Is Dangerous These days it can be very difficult to tell if a site is trustworthy or not. Many nefarious sites are being designed to look respectable.

How the Bitcoin protocol actually works Many thousands of articles have been written purporting to explain Bitcoin, the online, peer-to-peer currency. Most of those articles give a hand-wavy account of the underlying cryptographic protocol, omitting many details. Even those articles which delve deeper often gloss over crucial points. My aim in this post is to explain the major ideas behind the Bitcoin protocol in a clear, easily comprehensible way. Understanding the protocol in this detailed way is hard work. I’ll describe Bitcoin scripting and concepts such as smart contracts in future posts. It may seem surprising that Bitcoin’s basis is cryptography. My strategy in the post is to build Bitcoin up in stages. This strategy is slower than if I explained the entire Bitcoin protocol in one shot. Finally, I should mention that I’m a relative newcomer to Bitcoin. First steps: a signed letter of intent So how can we design a digital currency? On the face of it, a digital currency sounds impossible. Proof-of-work “Hello, world!” to .
Ten Steps You Can Take Right Now Against Internet Surveillance One of the trends we've seen is how, as the word of the NSA's spying has spread, more and more ordinary people want to know how (or if) they can defend themselves from surveillance online. But where to start? The bad news is: if you're being personally targeted by a powerful intelligence agency like the NSA, it's very, very difficult to defend yourself. The good news, if you can call it that, is that much of what the NSA is doing is mass surveillance on everybody. With a few small steps, you can make that kind of surveillance a lot more difficult and expensive, both against you individually, and more generally against everyone. Here are ten steps you can take to make your own devices secure.

An Introduction to Graphviz via R. Kelly’s “Trapped in the Closet” Hip Hopera : Rob's Blog As our world becomes more connected it has become of the utmost importance to clearly and easily visualize the structures that represent the modern digital age: the graph. Anyone involved in object oriented programming, artificial intelligence, networks, social media, or of course the fascinating field of graph theory makes heavy use of these structures. Graphs are a fertile topic that I plan to write more about, but for now we will focus on the immediately practical: the fantastic open source graph visualization toolkit Graphviz. Let us explore some of the useful features of Graphviz and its associated description language “dot” by tracing the convoluted relationships of the characters in R. Like every other web tutorial I will solipsistically assume you are using the same OS I am, Ubuntu. At this point our hero, “Sylvester”, played by R. Now compile: Note this will output a .jpg image but many other output formats are possible. As R. Note red edges signify infidelity.
Peacekeeper - free universal browser test for HTML5 from Futuremark Free Online Course Materials | Courses Caching Tutorial for Web Authors and Webmasters for Web Authors and Webmasters This is an informational document. Although technical in nature, it attempts to make the concepts involved understandable and applicable in real-world situations. What’s a Web Cache? A Web cache sits between one or more Web servers (also known as origin servers) and a client or many clients, and watches requests come by, saving copies of the responses — like HTML pages, images and files (collectively known as representations) — for itself. There are two main reasons that Web caches are used: To reduce latency — Because the request is satisfied from the cache (which is closer to the client) instead of the origin server, it takes less time for it to get the representation and display it. Kinds of Web Caches Browser Caches If you examine the preferences dialog of any modern Web browser (like Internet Explorer, Safari or Mozilla), you’ll probably notice a “cache” setting. Proxy Caches Web proxy caches work on the same principle, but a much larger scale.
PRISM fears give private search engine DuckDuckGo its best week ever If you want to know just how crazy fear over PRISM-like surveillance has made the Internet, take a look at DuckDuckGo. Thanks to the National Security Agency leaks and some well-timed media appearances, the private search engine is having its best traffic week ever. Visitors to the site made a record 2.35 million direct searches on Wednesday — a 26 percent increase over the previous week. For DuckDuckGo founder Gabriel Weinberg, the numbers are proof yet again that people are eager to find and use viable alternatives to popular web services, which are prime targets for government snooping. DuckDuckGo was launched in 2008 and has since become the foremost search engine for those concerned about not just snooping by the government but Google as well. Above: Traffic to DuckDuckGo tends to spike whenever new privacy fears pop up. “I believe the surveillance story is paramount right now, and people are talking about it.
