Java Programmers Competition 2016 IPPC: $500,000 cash prizes

SHOW ME YOUR SPEED!

We are already convinced that there are many gifted programmers and ingenious hackers.

    Now we want to know who the fastest and most flexible are.
After all, we are in the century of speed:

TIME = $

Next Hacker: International Programming Player Competition, February 26 & 27, 2016 in Berlin, Germany, the 2016 IPPC promises an exciting two days of intriguing events and programming competitions featuring 3,000 of the world’s best up and coming developers and programmers in an extreme and exciting skill competition.

IPPC’s main event is where the true competition really begins and everyone can be a winner in the Xtrem Programming Competition Speed & Skill Challenge. $500,000.00 cash prize they await the winners. This multi-stage challenge starts with each programmer having to successfully find and fix errors in three random Java programs.  Once that phase is completed, the programmer needs to achieve a score of 150,000 points in a single Classic Pac-Man game.  Once both tasks are completed, the fastest programmers win a share of the cash pool.  In addition, contestants’ contest performance information will be made available for all Companys.

The 2016 International Programming Player Competition will also offer technical sessions on programming, an open panel discussion with renowned hackers and programmers, and the opportunity for the world’s top programmers to be exposed to and meet leading high tech companies from around the globe.  The two day IPPC is open to programmers worldwide and space is filling up rapidly. All the money from our sponsors and advertisements that will be gathered will increase the winner’s number.

Amputee Can Control and ‘Feel’ using a Robotic Arm

My favorite technology news blog has posted another post!

Technology

A brand new advanced robotic hand that’s wired directly into the brain has been successfully tested, permitting a paralysed man to “feel”.

The hand, developed by the Applied Physics Laboratory at Johns Hopkins university, is part of a research venture into advanced replacement limbs funded by the US army’s Defence Advanced Research Projects Agency (DARPA).

The 28 year old person, who has been paralysed for more than a decade after a spinal-cord injury, had electrodes from the prosthetic hand inserted into his sensory and motor cortexes. This allowed him to both control the hand with his ‘thoughts’ and sense when the fingers of the hand were touched individually.

Sensors in the hand detect pressure applied to any of the fingers and create electrical signals to mimic touch sensations. When blindfolded, the volunteer could determine which finger on the hand was touched with practically 100% accuracy, according to DARPA.

“At one point, instead of pressing one finger, the team decided to press two with out telling him,” DARPA program manager Justin Sanchez said. “He responded in jest asking whether somebody was trying to play a trick on him. That’s when we knew that the feelings he was perceiving through the robotic hand were near-natural.”

Sanchez added: “Prosthetic limbs that can be controlled by thoughts are showing great promise, but with out feedback from signals traveling back to the mind it can be tough to achieve the level of control needed to carry out precise movements.”

By wiring a sense of touch from a mechanical hand directly into the brain, this work shows the potential for seamless biotechnological restoration of near-natural function. We’ve completed the circuit.”

The hand and the neurotechnologies on which it relies are hoped to permit those that have lost limbs to not only gain fully functioning replacements but also the level of control that may only be provided with sensation.

Facebook is introducing the ‘Dislike’ button

My favorite technology news blog has posted another post!

Technology

Facebook is working on a “dislike” button for its posts. This was revealved by the company’s co-founder and chief Mark Zuckerberg, during a question and answer session on Tuesday.

“People have asked about the ‘dislike’ button for many years, and probably hundreds of people have asked about this, and today is a special day because today is the day that I really get to say we’re working on it, and are very close to shipping a test of it,” he stated.

The “dislike” button has been a subject of much discussion through the years.

CEO Mark Zuckerberg revealed the plans for such a button during a Q&A session on the company’s headquarters Tuesday. The thought for such a brand new feature, which the social network plans to start testing soon, has been shot down by Zuckerberg and different Facebook executives before. However moving beyond “Like” is key to growing Facebook’s ability to surface a greater variety of content folks really care about.
Dislike much?
It will NOT be called the ‘dislike’ button

The centerpiece of the Facebook experience is the News Feed, the individualized stream of stories, articles, cat photos and old style status updates you see whenever you go to the social network’s web site or app. Facebook uses an algorithm to curate the News Feed, because there’s simply too much content material to show all of it in chronological order as it once did. Each time you go to the News Feed, Facebook’s algorithm kicks into gear, sorting all of the available posts from your pals, pages you’ve liked and advertisers into order based on what it thinks you’ll find most interesting.

Facebook can’t read minds (yet), so the firm can only guess as to which posts every consumer will care the most about. The News Feed algorithm takes under consideration hundreds of factors to determine its ranking, ranging from how much you tend to watch video posts to how often a person has clicked the poster’s profile photos. Plenty of it amounts to painstaking guesswork.

However clicking Like is totally different. It’s binary and unequivocal. You either Like something or you don’t. Due to this fact, it’s one of the biggest elements in News Feed’s secret sauce. Posts that get plenty of Likes from some users are positioned higher up in other users’ feeds because it’s assumed they’ll appeal to even more engagement and Likes.

That works to some extent, however it doesn’t necessarily assist Facebook meet its stated goal of “connecting the world.” After all, the 1.5 billion humans (and some dogs, cats and robots etc) using Facebook experience a variety of feelings in addition to “Like.” As the social network increasingly positions itself as a destination for news and thought-provoking conversations, “Like” grows ever more restrictive. Customers don’t want to “Like” an article about the struggles of Syrian refugees or give a thumbs up when a buddy shares that a loved one has died. Thus, Facebook’s algorithm might bury this kind of essential content material under traditional Internet catnip.

So “Dislike,” or whatever it winds up being known as, might provide a counterbalance to that phenomenon, making it simpler for customers to signal interest in a post or story that would be awkward to “Like.” Though Zuckerberg didn’t explain precisely how a dislike button would work, it certainly won’t be framed as a way to hate on your cousin’s cat photos. Facebook already has tools that allow individuals to hide posts, people and ads that they don’t care about. “Dislike,” then, is about opening up an avenue for users to interact with interesting content that would be awkward to do anything with inside Facebook’s present framework.

“If you’re expressing something sad . . . it may not feel comfortable to ‘like’ that post, but your pals and other people need to have the ability to express that they understand,” Zuckerberg stated on Tuesday.
