The AllSeen Alliance is an effort to standardize device communications. The code that it champions, called AllJoyn, was initially developed by Qualcomm but was subsequently made open source. Big vendors have been recruited to support it, and the AllSeen Alliance now includes LG, Panasonic, Sharp and Haier, among others.

This approach of binding our smart devices to our personal accounts may be an easy engineering decision today, but it will make less sense as more devices show up in households with multiple family members. Families shouldn’t be forced to decide if the dishwasher is bound to Mom’s Gmail account or Dad’s. Instead, the household should have its own identity, with different family members having different levels of access depending on their needs.

Not sure why a dishwasher or any household appliance would need user authentication or even user management. Does it matter if the person doing dishes is authorized as long as the dishes get washed?
You’ll learn how data is replicated within a cluster, how failover occurs, and the evolution of how his team decided to split data across a cluster of machines. Paul also touches on distributed consensus with Raft, replication fault tolerance with a write ahead log, and how we schedule frequent tasks to run in a reliable way across a cluster.

With the help of some advanced selectors a dropdown menu can be easily created with CSS. Throw in some fancy CSS3 properties and you can create a design that was once only achievable with background images and Javascript. Follow this tutorial to see the step by step process of building your own pure CSS dropdown menu.

But algorithms are also a reminder that visualization is more than a tool for finding patterns in data. Visualization leverages the human visual system to augment human intellect: we can use it to better understand these important abstract processes, and perhaps other things, too.
TQP has been arguing for years that using Secure Sockets Layer (SSL) or Transport Layer Security (TLS) combined with the RC4 encryption cipher infringes its patent. The company’s former owner, renowned “patent troll” Erich Spangenberg, acknowledged during a trial last year that he has made more than $45 million in settlements on the TQP patent. TQP is one of dozens of patent groups that he owns.

“Of course, least positively of all, another angle for many publishers is in-app purchasing – why provide a feature as a hidden cheat when you can get people to pay money to unlock it?” Seavor has also noticed this trend. “Bigger publishers have now realised you can actually sell these things to players as DLC. Want that special gun? Think you can unlock it with a cheat code? Nope! You’ve got to give us some money first!”
It turns out that when you shrink a Vacuum transistor to absolutely tiny dimensions, you can recover some of the benefits of a vacuum tube and dodge the negatives that characterized their usage. According to a report in IEEE Spectrum, vacuum transistors can draw electrons across the gate without needing a physical connection between them. Make the vacuum area small enough, and reduce the voltage sufficiently, and the field emission effect allows the transistor to fire electrons across the gap without containing enough energy to energize the helium inside the nominal “vacuum” transistor. According to researchers, they’ve managed to build a successful transistor operating at 460GHz — well into the so-called “Terahertz Gap,” which sits between microwaves and infrared energy. The “gap” refers to the fact that we have a limited number of devices that can generate this frequency and only a handful of experimental applications for this energy band.

Normally, Fang explains, stiffness and strength declines with the density of any material; that’s why when bone density decreases, fractures become more likely. But using the right mathematically determined structures to distribute and direct the loads — the way the arrangement of vertical, horizontal, and diagonal beams do in a structure like the Eiffel Tower — the lighter structure can maintain its strength.

In any case, it would be mistaken to read the case as grounds for invalidating all software patents.
But it most certainly does provide a basis for invalidating some bad software patents. This is progress. As lower courts apply the Supreme Court decision, we may see more progress.
