Cosmic Latte is a name assigned to the average color of the universe, given by a team of astronomers from Johns Hopkins University. Discovery of the color In 2001, Karl Glazebrook and Ivan Baldry determined that the color of the universe was a greenish white, but they soon corrected their analysis in a 2002 paper, in which they reported that their survey of the color of all light in the universe added up to a slightly beigeish white. The finding of the "color of the universe" was not the focus of the study, which was examining spectral analysis of different galaxies to study star formation. Glazebrook's and Baldry's work was funded by the David and Lucile Packard Foundation. As light from distant galaxies reaches the Earth, the average "color of the universe" (as seen from Earth) marginally increases towards pure white, due to the light coming from the stars when they were much younger and bluer. Naming of the color The color was displayed in a Washington Post article.

(Here is something I wrote for 13.7 on this a few weeks back.) We may start with Aristotle, who decided that "Nature abhors a vacuum" and thus declared that there was no such thing as nothing, understood as absolute emptiness. Spaced was filled up with aether, the same stuff that made up all celestial objects, from the moon up. Fast forward to the early 17th century and Descartes also states that there is no such thing as empty space. When Newton entered the scene, he would take aim at Descartes' plenum, showing it to be an impossibility: if there were such stuff in space, orbits would be unstable and the Moon would spiral down toward us. Since motion has energy, the Uncertainty Principle also says that energy is never really zero.
Digital Scent Technology BlogBIRMINGHAM, Ala.–(BUSINESS WIRE)–An unorthodox software company has achieved a first in the volatile, rapidly evolving world of computer technology: cutting edge software that allows computer users to enjoy aromatherapy in a variety of scents…through their computer speakers. Â ScenTeck Technologies released its Scratch-N-Sniff Pro(TM) downloadable software to the World Wide Web last month, and consumer reaction couldn’t be more positive. Scratch-N-Sniff Pro(TM) downloads reached the one million mark in less than a month after their release, and thousands continue to make downloads every day. “We started with a simple question,” said ScenTeck’s founder and chief scientist, Dr. Working with a special team of University scientists, the Germany-based Dr. Hriful’s team developed a System Scent Card that reacts to normal auditory sensors generated from a computer’s hard drive. Due to anticipated demand, the Web site will be launched on a Sunday, April 1, rather than during the week.

Magnetosphere in SoundOne of NASA's newest missions has recorded the radio waves coming from our magnetosphere. Musicians: Sample away. A graphic of Earth's twin rings of plasma known as the Van Allen Radiation Belts in our planet's magnetosphere (NASA) Surrounding our planet are rings of plasma, part of Earth's magnetosphere, which are pulsing with radio waves. The noises, often picked up here on Earth by ham-radio operators, are called Earth's "chorus" as they are reminiscent of a chorus of birds chirping in the early morning.
Unusual animal behaviour homosexual necrophilia in the mallardIn the summer of 1995, Kees Moeliker, a dutch researcher, was sitting behind his desk in the glass building of the Rotterdam Natural museum. Suddenly he was alerted by an unusual loud bang coming from the direction of the window. Outside the building, a male mallard (the common wild duck) was found dead, laying on its belly in the sand. Next to the dead duck, another male mallard was present that forcibly picked the dead duck’s head for a few minutes after which it mounted the corpse and began forcefuly copulating with it. The amorous male duck on the left copulated for over an hour with the corpse of another male duck that was found dead after flying against a glass wall. This bizarre observation is unique because homosexual necrophilic behaviour has never been described before. The author explained that at the time of the collision with the window the two mallards were probably engaged in the common rape flight which is a normal reproductive strategy in mallards.
4 super profils d'ingénieurs data en 2015 !Lesjeudis.com D'après la dernière étude mensuelle du cabinet Robert Half Technologie, les entreprises sont à l'affût de 4 profils très recherchés dans la data. Premier métier "en or", celui de Data Scientist, dont l'objectif est d'aider à la prise de décision à partir de l'analyse de données. Le salaire d'un Data Scientist peut dépasser les 50 000 euros par an. Deuxième métier visé : Digital/Web Analyst, chargé d'analyser les données des internautes.Elon Musk's Mission to Mars | Wired ScienceMaverick entrepreneur Elon Musk Photo: Art Streiber When a man tells you about the time he planned to put a vegetable garden on Mars, you worry about his mental state. But if that same man has since launched multiple rockets that are actually capable of reaching Mars—sending them into orbit, Bond-style, from a tiny island in the Pacific—you need to find another diagnosis. All entrepreneurs have an aptitude for risk, but more important than that is their capacity for self-delusion. I have never met an entrepreneur who fits this model more than Elon Musk. And he is leading the private space race with SpaceX, which is poised to replace the space shuttle and usher us into an interplanetary age. It’s no wonder the character of Tony Stark in Iron Man, played by Robert Downey Jr., was modeled on Musk: This is superhero-grade stuff. A Merlin engine Photo: Art Streiber Chris Anderson: You’re not a rocket scientist by training. Elon Musk: That’s true. Anderson: And of course there was nothing.
Chlorine trifluorideChlorine trifluoride is an interhalogen compound with the formula ClF3. This colourless, poisonous, corrosive, and extremely reactive gas condenses to a pale-greenish yellow liquid, the form in which it is most often sold (pressurized at room temperature). The compound is primarily of interest as a component in rocket fuels, in industrial cleaning and etching operations in the semiconductor industry, in nuclear reactor fuel processing, and other industrial operations. Preparation, structure, and properties It was first reported in 1930 by Ruff and Krug who prepared it by fluorination of chlorine; this also produced ClF and the mixture was separated by distillation. 3 F2 + Cl2 → 2 ClF3  Reaction with several metals give chlorides and fluorides; phosphorus yields phosphorus trichloride (PCl3) and phosphorus pentafluoride (PF5); and sulfur yields sulfur dichloride (SCl2) and sulfur tetrafluoride (SF4). ClF3 + 2H2O → 3HF + HCl + O2 ClF3 + H2O → HF + HCl + OF2 Uses
Social, Agile, and Transformation: The Key to aligning Agile Dev and Stable Ops to a Successful DevOps TransformationSo who does own DevOps? I left readers with this cliffhanger after my last post and my intro post on The What, Why and How of DevOps. If an organization is embarking on a DevOps transformation, how should it be led so that Dev and Ops teams are likely to collaborate more and battle less in adapting and maturing new practices? To answer this question, I would suggest we get back to basics and review the role of Dev and Ops in an IT organization. Dev Must Align with Business Priorities The Development team should operate as the technology extension of the business. Therein lies a key question - what is support? And... it can also be anything technical to make the Development team more efficient. Many Dev teams have adopted agile development practices to better align with the business and to focus their development efforts. Operations Align with Stability and Reliability The byproduct of protecting the organization is often rigidity. DevOps Practices Align Development and Operations
