Welcome to the distribution center for BYOB (Build Your Own Blocks), an advanced offshoot of Scratch, a visual programming language primarily for kids from the Lifelong Kindergarten Group at the MIT Media Lab. This version, developed by Jens Mönig with design input and documentation from Brian Harvey, is an attempt to extend the brilliant accessibility of Scratch to somewhat older users-in particular, non-CS-major computer science students-without becoming inaccessible to its original audience. BYOB 3 adds first class lists, sprites, and procedures to BYOB's original contribution of custom blocks and recursion.
We present results of a 45-participant laboratory study investigating the usability of tools to limit online behavioral advertising (OBA).We tested nine tools, including tools that block access to advertising websites, tools that set cookies indicating a user's preference to opt out of OBA, and privacy tools that are built directly into web browsers.
Technical innovations are advancing day by day. But, along with this irritating and sometimes destructive pop-up ads are also there. To avoid this hindrance, you need to turn-off your pop-up so as to experience ultimate web-surfing. Here is this tutorial to let you know the way of blocking these pop-ups.
A feature article at the TeraGrid website takes a look at the most common building blocks of today's supercomputers, the ubiquitous CPUs and GPUs. Interest in GPUs was already high when China's Tianhe-1A supercomputer achieved a number one TOP500 ranking using the power of the graphics chips.
You often use the "Reply All" button in group communication. At that time, it may seem convenient, though it may be distressing later one, when different recipients start reverting on it, even when you don't expect. No matter how many times you delete these messages from your inbox, the next message in the chain will make it all come flashing back.
Spamming is generally unsolicited communication targeted to deceive users with tricky messages from remote locations. However, most of you live in a misconception that spamming is confined only to email service. Such communication may leave you in puzzled state even with the Web-based services like Facebook, Twitter or LinkedIn.
This is an example of building a tree layout using the Reingold-Tilford "tidy" algorithm, as described in "Tidier Drawings of Trees". As each new element is added to the graph, it animates in, starting at the previous position of the parent node. Thus, the existing nodes and the new node transition smoothly to their new positions. The animation stops when 500 nodes have been added to the tree.
