Distributed peer-to-peer (P2P) networking delivers the new blocks and transactions and is critical for the cryptocurrency blockchain system operations. Having poor P2P connectivity reduces the financial rewards from the mining consensus protocol. Previous research defines beneficalness of each Bitcoin peer connection and estimates the beneficialness based on the observations of the blocks and transactions delivery, which are after they are delivered. However, due to the infrequent block arrivals and the sporadic and unstable peer connections, the peers do not stay connected long enough to have the beneficialness score to converge to its expected beneficialness. We design and build Dynamic Peer Beneficialness Prediction (DyPBP) which predicts a peer's beneficialness by using networking behavior observations beyond just the block and transaction arrivals. DyPBP advances the previous research by estimating the beneficialness of a peer connection before it delivers new blocks and transactions. To achieve such goal, DyPBP introduces a new feature for remembrance to address the dynamic connectivity issue, as Bitcoin's peers using distributed networking often disconnect and re-connect. We implement DyPBP on an active Bitcoin node connected to the Mainnet and use machine learning for the beneficialness prediction. Our experimental results validate and evaluate the effectiveness of DyPBP; for example, the error performance improves by 2 to 13 orders of magnitude depending on the machine-learning model selection. DyPBP's use of the remembrance feature also informs our model selection. DyPBP enables the P2P connection's beneficialness estimation from the connection start before a new block arrives.
Elon Musk and the problem with immortality - by Ginger Liu
Interactive internet-based technologies are transforming the way in which we understand death, grieving, and coping with loss. Online communication together with changes in social and religious attitudes in western society has created a space where the individual is part of the collective. The transition from analog to digital combines the private with the public and the real with the virtual. Feeding the digital afterlife zeitgeist are tech giants who are eager to build a synthetic heaven where big egos go to die. The idea of a synthetic heaven is offensive to many with long-standing religious beliefs even though those same beliefs are as synthetic as digital data.

The Future of Work: 'Remembrance,' by Lexi Pandell
When the podcar strikes me, I see a flash. For a long moment, I am nothing more than an electric white shock of pain. My blurred vision only perceives shadowy forms, but I can imagine what they look like in their gray jumpsuits, each of them fitted with goggles that display my vitals. They've cut off my shirt. "Is she stable enough to save?" an e-medic asks.
Remembering Marvin Minsky
Forbus, Kenneth D. (Northwestern University) | Kuipers, Benjamin (University of Michigan) | Lieberman, Henry (Massachusetts Institute of Technology)
Marvin Minsky, one of the pioneers of artificial intelligence and a renowned mathematicial and computer scientist, died on Sunday, 24 January 2016 of a cerebral hemmorhage. In this article, AI scientists Kenneth D. Forbus (Northwestern University), Benjamin Kuipers (University of Michigan), and Henry Lieberman (Massachusetts Institute of Technology) recall their interactions with Minksy and briefly recount the impact he had on their lives and their research. A remembrance of Marvin Minsky was held at the AAAI Spring Symposium at Stanford University on March 22. Video remembrances of Minsky by Danny Bobrow, Benjamin Kuipers, Ray Kurzweil, Richard Waldinger, and others can be on the sentient webpage1 or on youtube.com.

McCarthy's strengths as both theoretician and engineer, John McCarthy, famous for his role in the development and explore how these drosophilae shaped his of time-sharing, for inventing the computer research. Since is talk analyzes McCarthy's myriad contributions 2010, she has served as principal investigator of the to artificial intelligence and knowledge representation Evaluation and Knowledge Infrastructure Team for through the set of drosophilae that he proposed, DARPA's Machine Reading Program.
Donald E. Walker: A Remembrance
Grosz, Barbara, Hobbs, Jerry R.
He knew the challenges opinion, as one of the premier natural language were great and would require the research groups in the world. He gave efforts of many people. He had a genius for one of us (Barbara Grosz) her first AI job, even bringing these people together. In doing so, he took a of people who had known Don over the risk of a magnitude that she fully appreciated years to send us reminiscences. Although only years later when she herself was hiring each person's story differed, a striking commonality research associates.
