Inside the tech that makes ‘near-miss’ air collisions almost impossible

Surely then, it’s not surprising that we hear of “near-misses” between passenger jets, and of “hero pilots” avoiding “mid-air collisions”? Well yes, actually it is, because that can’t happen. These so-called “near-misses” are still a long way off from being a collision. Take the recently reported news of an Emirates Airbus A380 and an Air Seychelles Airbus A330 travelling from Mauritius to the Seychelles, for example. The two planes came closer than the safety margin required by regulations: all…

Construction of massive neutrino experiment kicks off a mile underground — ScienceDaily

A new era in international particle physics research officially began July 21 with a unique groundbreaking held a mile underground at the Sanford Underground Research Facility in South Dakota. Dignitaries, scientists and engineers from around the world marked the start of construction of a massive international experiment that could change our understanding of the universe. The Long-Baseline Neutrino Facility (LBNF) will house the international Deep Underground Neutrino Experiment (DUNE), which will be built and operated by roughly 1,000 scientists and…

Pokemon’s Epic Fail in Chicago

Full disclosure:  I generally don’t play games much anymore, whether video, online, offline, board, ball, table, or hunger.  So anything I write about games is going to be at one remove as an observer, not a participant.  That isn’t necessarily bad, but in case you are an enthusiastic game player, you should know I am an outsider to all that. Nevertheless, I can imagine what it would be like to get involved in Pokemon, the online mobile phone game, to…

Optimization for self-production may explain mysterious features of the ribosome — ScienceDaily

Optimization for self-production may explain key features of ribosomes, the protein production factories of the cell, reported researchers from Harvard Medical School in Nature on July 20. In a new study, a team led by Johan Paulsson, professor of systems biology at Harvard Medical School, mathematically demonstrated that ribosomes are precisely structured to produce additional ribosomes as quickly as possible, in order to support efficient cell growth and division. The study’s theoretical predictions accurately reflect observed large-scale features of ribosomes…

Creating #DataScienceHappiness | LinkedIn Engineering

In a previous post, I gave some advice for those who are interested in a career in data science. One of the suggestions I made was to find a work environment that values and promotes a good data science culture. This is a concept I like to call #DataScienceHappiness, and I believe it’s key for companies that want to get the most out of their data science programs. In order to maximize the return from data science, companies must keep…

Artificial intelligence boosts wine’s bottom line

Credit: Ailytic The Australian wine industry is turning to artificial intelligence to streamline its manufacturing. South Australian tech firm Ailytic has developed an artificial intelligence (AI) program to significantly increase production efficiency by optimising machine use. It uses an AI technique called ‘prescriptive analytics’ to account for all the variables that go into mass-producing wines such temperature, wine changeover and inventory. The program then creates the best possible operation schedule, allowing companies to save considerable time and money.…

Models reveal nanoindentation can benefit crystals in concrete — ScienceDaily

Rice University scientists have determined that no matter how large or small a piece of tobermorite is, it will respond to loading forces in precisely the same way. But poking it with a sharp point will change its strength. Tobermorite is a naturally occurring crystalline analog to the calcium-silicate-hydrate (C-S-H) that makes up cement, which in turn binds concrete, the world’s most-used material. A form of tobermorite used by ancient Romans is believed to be a key to the legendary…

New open source IT cookbooks for macOS – Pinterest Engineering – Medium

Erik Gomez | Pinterest engineer, IT Client Platform Over the last year, Pinterest IT has been moving away from traditional device management frameworks to an almost completely open source model. Our team’s goal is to make minimal user roadblocks while also maintaining a secure and safe platform for employees. While we’ve done this for years with traditional MDM tools, it often came at a cost. For example, there were increased engineering hours spent writing tool extensions, and code was often…

Building open source tools for Adobe Creative Cloud updates | Engineering Blog | Facebook Code

Many IT shops focus on delivering prepackaged, vendor-based software to employees. As companies begin to offer services to millions or even billions of people, their internal systems, technical environments, and licensing strategies must evolve to give teams the flexibility and speed to keep up with the growing business. For Facebook, and perhaps for any company that operates at our scale, delivering enterprise tools across an organization is becoming an engineering challenge. One area that can occupy countless IT hours is…

Using sensors and social networks to make slopes safer

Jim Christian SM ’14 is co-founder and vice president of product for Mountain Hub, an app-based network in which people can upload and share critical real-time information about outdoor conditions. Credit: Jim Christian The peace and quiet that envelope a lone hiker on a leaf-riddled trail or a rock climber perched on the top of a cliff seem a world away from the noise of a social media feed. But Department of Mechanical Engineering (MechE) alumnus Jim Christian SM ’14…
