Linux Foundation takes Linux pulse in progress report

first_img(PhysOrg.com) — A white paper updating 2011 highlights and progress in Linux kernel development has been released by The Linux Foundation, the vendor-neutral base for collaborations on the Linux kernel. “Linux Kernel Development: How Fast it is Going, Who is Doing It, What They are Doing, and Who is Sponsoring It” is authored by Jonathan Corbet, LWN.net, Greg Kroah-Hartman and Amanda McPherson, the latter two of The Linux Foundation. Citation: Linux Foundation takes Linux pulse in progress report (2012, April 5) retrieved 18 August 2019 from https://phys.org/news/2012-04-linux-foundation-pulse.html The walls are history. In addition to Red Hat stepping up to the plate to expand Linux for business, IBM also was one of the earlier industry heavyweights turning partners and clients on to Linux. Similar turnarounds happened quickly; in 2012 Linux is everywhere, running supercomputers, financial trades, and mobile devices.This is the fourth update of the status report and in addition to stats the report talks about 2011 highlights, one among them being that the Linux kernel celebrated its twentieth anniversary along with the release of the 3.0 kernel. Another notable in 2011: Microsoft appeared on the list of the top-20 contributors for a kernel release. Microsoft ranks 17th, with a contribution estimated at 1 per cent of the whole.The report not surprisingly names Red Hat, IBM, Intel, Novell, Oracle, and others as among key company contributors. The latest twist, as shown in the report’s graph, is that Samsung and Texas Instruments are rising stars as key contributors. “There is an interesting trend to be seen in the following plot,” says the report, referring to the graph. “They correspond to the contributions from Samsung and Texas Instruments, both of which are prominent mobile and embedded companies. In recent years, the level of participation from this sector has been growing rapidly. It is worth noting that these companies are not only adding more hardware support to the kernel, they are also taking more responsibility for the advancement of core kernel areas like the scheduler and memory management.”The report also accounts for Linux downs as well as ups last year. The report did not neglect to mention that in 2011 the central repository and distribution site for kernel development,kernel.org, suffered a severe security breach and was offline for several weeks. More information: www.linuxfoundation.org/public … ons/linux-foundation This report covers a wide range of stats, from the number of files and lines in each kernel version to individual changes that go into each kernel release, to numbers of developers doing kernel development, to companies working on kernel improvements.The number of different developers who are doing Linux kernel development and the identifiable companies who are sponsoring this work have been increasing over the different kernel versions, says the report. Statements like that really stand out, if one considers the earliest days of Linux, when coders down in the trenches of computer labs at big companies were warned not to do “Open Source stuff” during office hours. Corporate finance executives who did not grasp programming thought of Linux as a cult-like threat to capitalist growth. If Ballmer was calling Linux a “cancer,” some businesses also saw Linux as a threat to the way they thought businesses need to survive. The very idea of sharing changes with people across companies was far less familiar than staying proprietary. The difficulty in seeing the benefits of Open Source software development practices, and not just the operating system, threw up walls against Linux. center_img Linux Kernel to Add VMI © 2012 PhysOrg.com Explore further This document is subject to copyright.

Study shows economic studies done in lab offer similar results to those

first_img There has been some debate in the economics field regarding the validity of economic experiments done in the lab due to the constrained environment in which they are conducted. Until now however, as the research pair point out, very few if any studies have been done to find out if such concerns are warranted—to find out, they designed and conducted a study on earlier studies.The study consisted of analyzing the results of studies done on what is known as the spillover effect—where productivity in a group goes up if just one member of a group increases his or her productivity. The research pair found data from 34 such studies, 11 done in the lab and 23 in the field over the past fifteen years, and compared the results. They found only very small differences, suggesting that the work done in the lab was every bit as valid as the work done in the field.Charness and Fehr suggest that there is a reasonable explanation for the results—it is because those conducting work in the lab add aspects to their studies to counter the effects of the lab environment. Incentives can be added, they note, or volunteers can be used that are not university students, or by offsetting the impact of behavior changes that result from being observed by offering comparisons to workers that do their work in the real world under observation. For this reason, they suggest the results found by Herbst and Mas likely apply under other scenarios as well, which might be enough to cause some scientists to change their views on lab studies.

Journal information: Science (Phys.org)—A pair of economics researchers has found evidence that suggests that economic studies done in the lab offer results that are comparable to those done in the field. In their paper published in the journal Science, Daniel Herbst and Alexandre Mas with Princeton University, describe how they compared study results that used one or the other of the two methods and why they believe what they found likely translates to other studies as well. Gary Charness and Ernst Fehr with the Universities of California and Zurich respectively, offer a Perspective piece on the work done by the research pair in the same journal issue and offer some ideas on why the results from such studies were found to be similar.

Massive multiple star system found by astronomers

first_img Another bee in the beehive—Astronomers discover binary star in the NGC 2632 cluster Explore further HD 64315 (also known as HIP 38430) is the main ionising source of the Galactic H ii region Sh2-311. It was initially classified by previous studies as a binary star, located some 16,000 light years away from the Earth. However, a new study conducted by Lorenzo’s team reveals breakthrough information about this stellar system.The researchers have analyzed over 50 high-resolution spectra of HD 64315 obtained during previous observations and also photometric data from All Sky Automated Survey and Hipparcos catalogs. This analysis revealed strong signatures of more than two components present in the spectra, indicating that HD 64315 is, in fact, a multiple system comprising at least four components.”By using a complex procedure to analyse 52 high-resolution spectra, we are able to confirm that HD 64315 contains two binary systems, one of which is an eclipsing binary,” the paper reads.According to the research, HD 64315 is composed of at least two binary systems, one of which is an eclipsing binary. The two binaries are located about 500 AU from each other.HD 64315 AaAb is the non-eclipsing binary with an orbital period of 2.7 days. Both components of this binary have minimal masses of at least 10 solar masses, but most likely about 30 solar masses.The eclipsing binary was designated HD 64315 BaBb and has a much shorter orbital period which equals approximately one day. Both stars of this binary have a similar mass of about 14.6 solar masses.The researchers found that HD 64315 AaAb’s components are hotter than those of the eclipsing binary, and dominate the appearance of the whole system. They estimate that HD 64315 has a total mass of above 90 solar masses. Notably, the eclipsing binary is one the most massive overcontact binaries known, a likely merger progenitor in a very wide multiple system.The team does not exclude the possibility that HD 64315 could be a compact cluster in which most of the mass could be concentrated in the two observed binaries. “Lower-mass components would not be observable in the glare of this very bright system. However, in any case, it is highly unlikely that HD 64315 is surrounded by a cluster with about 1,000 solar masses, as is usual for other O6 V stars,” the authors noted.In concluding remarks, the researchers emphasized that HD 64315 is potentially a massive hierarchical system that formed in a sparse environment, which highlights the need for detailed studies of multiplicity in apparently “isolated” stars.”HD 64315 provides a cautionary tale about high-mass star isolation and multiplicity. Its total mass is likely above 90 solar masses, but it seems to have formed without an accompanying cluster,” the scientists concluded. © 2017 Phys.org Citation: Massive multiple star system found by astronomers (2017, August 7) retrieved 18 August 2019 from https://phys.org/news/2017-08-massive-multiple-star-astronomers.html More information: arxiv.org/pdf/1708.00849.pdf A group of astronomers led by Javier Lorenzo of the University of Alicante, Spain, has discovered that the binary star system HD 64315 is more complex than previously thought. The new study reveals that HD 64315 contains at least two binary systems composed of massive stars. The findings appeared online on Aug. 2 in a paper published on arXiv.org.

There are ways to combat racism that dont rely on implicit bias

first_imgIt would be nice if, to address racism and sexism, we could simply call on people to change their subconscious prejudicial impulses. Unfortunately, despite the hype around “implicit bias” as a psychological tool for improving workplace diversity, it doesn’t work that way. As Quartz has previously reported, there are numerous methodological flaws with the most commonly used implicit-bias test, and relying on current techniques meant to address implicit bias doesn’t product strong long-term results. But that doesn’t mean we should give up on addressing bias altogether, argued Neil Lewis, professor of communication and social behavior at Cornell University, at this year’s Society for Personality and Social Psychology conference. Lewis said that when he first saw evidence showing that implicit-bias training doesn’t create long-lasting effects, he found it depressing. He originally planned to research implicit bias in graduate school, then changed his mind when he realized the effects of trainings based on the concept don’t last long, he says. “But over time I’ve come to view it as an important and useful reminder of a broader lesson from the behavioral sciences: people are highly influenced by their environment,” he wrote in the notes for his talk, which he emailed to Quartz. “The reasons they have those biases in the first place is because they’ve learned them from the contexts they’ve been embedded in—contexts that are rich with social scripts (norms) that influence our thoughts, feelings, and behavior.” Read the whole story: Quartzlast_img read more

Get off at the artscience junction

first_imgTo most of us, art and science are polar opposites. Whereas art is seen as purely subjective practice, science is expected to free itself from subjectivity in order to come as close to objectivity as possible. However, at a closer look, we shall discover that both artistic and scientific practices hove much more in common as it might initially appear. Talking about photography, it gives us a chance to preserve the moments that passed away. And when this art of photography couples with science it produces such show like DWIH Horizon: Art Meets Science. Also Read – ‘Playing Jojo was emotionally exhausting’Organised by the German House for Research and Innovation, the show displays photographs clicked by 18 young Indian photographers under the guidance of famous German artistic photographer Wolfgang Zurborn. The pictures exhibited at the show are based on the theme The Theatre of Real Life depicting everyday life in India. Captured by the artistes during the Photography Master Class conducted during the Excellence on Tour!  road shows in Ahmedabad and Kolkata in 2013/14, these photos have now been assembled into an inspiring exhibition by  Zurborn. Also Read – Leslie doing new comedy special with NetflixThe event that kick started on 28 October was inaugurated by Michael Steiner, Ambassador of the Federal Republic of Germany. Addressing the guests at the occasion, Steiner said, ‘The show aims to capture the gist of Indo-German academic creativity expressed through photography and scientific activities. It displays a cultural highlight combined with ample first hand information on research and innovation in Germany’.Jamila Adeli, Curator and Art historian gave a key note address highlighting the topic ‘What science can learn from Art and vice versa’. Adeli showed two video clips that beautifully explained the relation between art and science. The event also includes various scientific talks, lectures and workshops conducted by the DWIH New Delhi consortium members consisting of German universities, educational institutes and research funding organisations. On the final day of the event, these institutions will set up info-stands to disseminate all necessary information required by Indian students, scientists or researchers to pursue their careers in Germany.When: On till 1 November Where: IGNCA, Janpathlast_img read more

Unused waterbodies to be utilised for fish production

first_imgKolkata: Bengal government is chalking out a comprehensive road map in order to utilise all the unused waterbodies across the state for fish farming, thereby increasing the overall fish production in the state, state fisheries minister Chandra Nath Sinha said.He was speaking at ‘Fisheries Conclave: Maximising Production and Ensuring Safety’ organised by the Confederation of Indian Industry (CII) at a city hotel on Tuesday. Bengal has the potential to overtake Andhra Pradesh in fish production within the next couple of years, the minister said. Also Read – Rain batters Kolkata, cripples normal life”If we could utilise the unused waterbodies in the state for pisciculture through more scientific intervention, Bengal will surpass Andhra Pradesh in the near future. A lot of initiatives are being taken to educate people involved in fish farming. Our department is formulating a road map to increase fish production in the next couple of years,” Sinha said.Bengal has exported around 1.7 lakh metric tonne of fishes abroad including 70 thousand tonne of shrimps. Last year, the overall fish production in the state remained at 17.42 lakh metric tonne, while the fisheries department has set a target to increase the productivity up to 18. 5 lakh metric tonne in the next year. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedAccording to sources at the fisheries department, around 15 percent of waterbodies in the state have been lying unused. If these waterbodies could be used for pisciculture, fish production would be manifold. It may be mentioned that Chief Minister Mamata Banerjee has said Bengal will be self-reliant in case of fish production. Banerjee’s brain child ‘Jol Dhoro, Jol Bhoro’ project has significant contribution towards the increase in fish production in the state in the past few years. The Fisheries department has developed Moyna in Purba Medinipur district as Bengal’s largest fisheries hub, following instructions of the Chief Minister to cut down on fish imports from other states. A stress has been given to increase the productivity of small fishes as well. Steps have also been taken to use ponds for cultivating small fishes twice in a year. A study has been conducted to examine what species of fishes can be produced in which aquatic conditions in the districts, Sinha said.”We are trying to increase the production of prawns in the districts. Our department is setting up hatcheries in various places and fingerlings are being distributed among farmers by our department for free,” Sinha said.Soumyajit Das, Managing Director, the State Fisheries Development Corporation (SFDC) Ltd said farmers training, application of scientific food and medicine have been given utmost importance to maximise the production. Ravi Inder Singh, Principal Secretary, department of Fisheries said steps have been taken to strengthen cold chain management in the state. Focus is on creating infrastructure in production and exports of fishes, he added.last_img read more
