ACM Blames the PC For Driving Women Away From Computer Science

slashdot.org - dg, 24/08/2014 - 20:07
theodp (442580) writes "Over at the Communications of the ACM, a new article — Computing's Narrow Focus May Hinder Women's Participation — suggests that Bill Gates and Steve Jobs should shoulder some of the blame for the dearth of women at Google, Facebook, Apple, Twitter and other tech companies. From the article: "Valerie Barr, chair of ACM's Council on Women in Computing (ACM-W), believes the retreat [of women from CS programs] was caused partly by the growth of personal computers. 'The students who graduated in 1984 were the last group to start college before there was personal computing. So if you were interested in bioinformatics, or computational economics, or quantitative anthropology, you really needed to be part of the computer science world. After personal computers, that wasn't true any more.'" So, does TIME's 1982 Machine of the Year deserve the bad rap? By the way, the ACM's Annual Report discusses its participation in an alliance which has helped convince Congress that there ought to be a federal law making CS a "core subject" for girls and boys: "Under the guidance of the Education Policy Committee, ACM continued its efforts to reshape the U.S. education system to see real computer science exist and count as a core graduation credit in U.S. high schools. Working with the CSTA, the National Center for Women and Information Technology, NSF, Microsoft, and Google, ACM helped launch a new public/private partnership under the leadership of Code.org to strengthen high school level computing courses, improve teacher training, engage states in bringing computer science into their core curriculum guidelines, and encourage more explicit federal recognition of computer science as a key discipline in STEM discussions.""

If Java Wasn't Cool 10 Years Ago, What About Now?

slashdot.org - dg, 24/08/2014 - 19:09
10 years ago today on this site, readers answered the question "Why is Java considered un-cool?" 10 years later, Java might not be hip, but it's certainly stuck around. (For slightly more than 10 years, it's been the basis of the Advanced Placement test for computer science, too, which means that lots of American students are exposed to Java as their first formally taught language.) And for most of that time, it's been (almost entirely) Free, open source software, despite some grumbling from Oracle. How do you see Java in 2014? Are the pessimists right?

3 Years In, a "B" For Tim Cook's Performance at Apple

slashdot.org - dg, 24/08/2014 - 18:10
Cult of Mac has taken a look at the three years since Tim Cook began his job as Apple's CEO, and rates him a "solid B." Cook might be neither as charismatic or volatile as Steve Jobs was, but he's made some interesting moves and statements. One factor (an area in which Cult of Mac gives Cook an A) is employee happiness, something for which Jobs was not always known: Cook’s highest “grade” on this hypothetical report card may come from Apple employees. Though the lanky 53-year-old is reportedly short on small talk, his people skills have earned him a 93 percent approval rating from a sampling of almost 2,000 people who work at Apple on website Glass Door, where anonymous employees can rate their satisfaction with the overall work environment as well as give thumbs up or down for the CEO.

Mangalyaan Gets Ready To Enter Mars Orbit

slashdot.org - dg, 24/08/2014 - 17:14
William Robinson (875390) writes India's Mars Orbiter Mission, known as Mangalyaan is now at a distance of just nine million kilometres from the red planet, and is scheduled to enter the orbit of Mars at 7.30 am on September 24. Mangalyaan was launched on 5th November 2013 by ISRO, presently busy planning to reduce the speed of the spacecraft through the process of firing the LAM engine and bring it to 1.6 km/sec, before it is captured by the planet's gravity. Eventually, the mission's official updates page should catch up.

Sources Say Amazon Will Soon Be Targeting Ads, a la Google AdWords

slashdot.org - dg, 24/08/2014 - 16:18
According to The Register (citing a paywalled WSJ article), a new face in targeted ads is emerging (according to "people familiar with the matter") to compete with Google, and it's Amazon. They already have a vast, mineable collection of data about customers' buying, listening and viewing habits, so exploiting personalized ads seems a natural follow-on. According to the report, the ad system would replace Google as ad vendor on Amazon itself, and "It is also apparently hoping to beef up its ad placement business on other sites as part of Amazon's strategy to carve its way into Google's multi-billion-dollar AdWords' empire." Pretty soon Amazon will able to just save me time by ordering the things I would have ordered based on ads that they themselves have placed.

A New Homegrown OS For China Could Arrive By October

slashdot.org - dg, 24/08/2014 - 15:19
According to a Reuters report, China could have a new homegrown operating system by October to take on imported rivals such as Microsoft Corp, Google Inc and Apple Inc, Xinhua news agency said on Sunday. Computer technology became an area of tension between China and the United States after a number of run-ins over cyber security. China is now looking to help its domestic industry catch up with imported systems such as Microsoft's Windows and Google's mobile operating system Android. The operating system would first appear on desktop devices and later extend to smartphone and other mobile devices, Xinhua said, citing Ni Guangnan who heads an official OS development alliance established in March. It would make sense for even a "homegrown" operating system to be based on existing ones, in the way Red Flag Linux is. Conceptually related: Earlier this year, Chinese company Coship Electronics announced (and demonstrated) a mobile OS called 960 OS.

Magnitude 6.0 Quake Hits Northern California, Causing Injuries and Outages

slashdot.org - dg, 24/08/2014 - 14:11
As numerous sources report, an earthquake of magnitude 6.0 struck California early Sunday morning, with an epicenter about 9 miles south of Napa. According to the San Francisco Chronicle's account, Some power lines down in western Contra Costa County, but Bay Area bridges appeared to be fine, according to the California Highway Patrol. There were widespread reports of power outages, gas leaks and flooding in the North Bay, with at least 15,000 Pacific Gas and Electric Co. customers without power in Vallejo, Napa, Rohnert Park, Santa Rosa and Sonoma. Police reminded motorists to stop at darkened intersections. ... In Benicia, several miles from the epicenter, the quake was strong enough to knock pictures off mantles. Bay Area bridges appear to have survived the quake -- significant, in that the L.A. Times reports that USGS estimates peg it as "the largest earthquake to strike the Bay Area since the Loma Prieta temblor of 1989," and says that injury reports (especially from glass) are streaming in from the area around Napa. The Times also has a larger estimate of customers suffering power outages: "more than 42,000" around the northern Bay Area. Unsurprisingly, social media channels are full of pictures showing some of the damage. For those in California, did you feel the quake? (And from how far away?) Update: 08/24 13:15 GMT by T : Also in earthquake news: an even stronger quake (magnitude 6.4) on Saturday struck central Chile, shaking Santiago -- nearly 70 miles from the epicenter -- for more than half a minute, but with "no immediate reports of fatalities or serious damage."

Major Delays, Revamped Beta For Credit-Card Consolidating Gadget Coin

slashdot.org - dg, 24/08/2014 - 13:29
The premise behind Coin is attractive: consolidate credit cards onto a single card-sized gadget. However, on Friday the company announced a delay in the release of its final version from this summer to spring of 2015, and in a way that angered many of the project's crowd-funding backers. The announcement of a delay was not only sudden, and quite close to the previously announced shipping date, but upset those who'd pre-ordered by outlining a confusing beta program that would involve an interim product release — recipients of the beta version (limited to 10,000) would have had to then pay $30 to upgrade to the final product. As CNET reports, the delay until 2015 remains, but with regard to that beta program, Coin has now reversed its stance. The beta program will be free -- meaning preorder customers who opt-in will no longer forfeit the $55 they paid and will still receive the finished Coin product next year. The program will also expand from 10,000 customers to 15,000. Regardless of whether your smartphone is running Apple's iOS or Google's Android operating system, preorder customers can opt-in to Coin's beta program through its app and will be eligible for a device if they fall within the 15,000-person threshold. The order is determined by when you bought your Coin. Coin customers, some who placed orders as far back as November 2013 when the startup first opened its website for preorders, were displeased not so much with the product delay as with the way Coin handled the situation. The company had, as recently as August 14, sent out an update explaining that a long-awaited shipping announcement would arrive at month's end --yet without an indication that it may miss its shipping target.

Among Gamers, Adult Women Vastly Outnumber Teenage Boys

slashdot.org - dg, 24/08/2014 - 12:01
MojoKid writes: The Entertainment Software Association has just released its 2014 report on the state of the video game industry (PDF), and as the title of this post suggests, there have been some significant shifts since the last report. Let's tackle the most interesting one first: Females have become the dominant gamer, claiming 52% of the pie. That's impressive, but perhaps more so is the fact that women over the age of 18 represent 36% of the game-playing population, whereas boys aged 18 and under claim a mere 17%. Statistics like these challenge the definition of "gamer." Some might say that it's a stretch to call someone who only plays mobile games a "gamer" (Candy Crush anyone?). Mental hurdle aside, the reality is that anyone who plays games, regardless of the platform, is a gamer.

Western US Drought Has Made Earth's Crust Rise

slashdot.org - dg, 24/08/2014 - 09:26
Loss of both groundwater and water stored in surface reservoirs in the drought-striken western U.S. isn't just expensive and contentious: it's evidently making the earth's crust rise in the West. Scripps researchers say that the average rise across a wide stretch of the West Coast is approximately one sixth of an inch. Scientists came to this conclusion by studying data collected from hundreds of GPS sensors across the Western U.S., installed primarily to detect small changes in the ground due to earthquakes. But the GPS data can also be used to show very small changes in elevation. The study specifically examined GPS stations on bedrock or very thin soil because it provides the most accurate measurement of groundwater loss, said Duncan Agnew, professor of geophysics at the Scripps Institution of Oceanography. Areas with thick soil, such as farms, can see the ground sinking as the soil dries out. But Agnew said the bedrock underneath that soil is actually rising. The highest uplift of the Earth occurred in California's mountains because there is so much water below them, Agnew said. The uplift was less in Nevada and the Great Basin.

Air Force Requests Info For Replacement Atlas 5 Engine

slashdot.org - dg, 24/08/2014 - 03:33
schwit1 (797399) writes The U.S. Air Force on Thursday issued a request for information from industry for the replacement of the Russian-made engines used by ULA's Atlas 5 rocket: "Companies are being asked to respond by Sept. 19 to 35 questions. Among them: "What solution would you recommend to replace the capability currently provided by the RD-180 engine?" Air Force officials have told Congress they only have a broad idea of how to replace the RD-180. Estimates of the investment in money and time necessary to field an American-built alternative vary widely. Congress, meanwhile, is preparing bills that would fund a full-scale engine development program starting next year; the White House is advocating a more deliberate approach that begins with an examination of applicable technologies. In the request for information, the Air Force says it is open to a variety of options including an RD-180 facsimile, a new design, and alternative configurations featuring multiple engines, and even a brand new rocket. The Air Force is also trying to decide on the best acquisition approach. Options include a traditional acquisition or a shared investment as part of a public-private partnership. [emphasis mine]" The Atlas 5 is built by Lockheed Martin. This is really their problem, not the Air Force or ULA. In addition, the Air Force has other options, both from Boeing's Delta rocket family as well as SpaceX's Falcon 9 rocket.

Slashdot Asks: Cheap But Reasonable Telescopes for Kids?

slashdot.org - dg, 24/08/2014 - 00:22
I am interested in a telescope for the use of some elementary and middle school aged relatives. Older and younger siblings, and parents, would no doubt get some scope time, too. Telescopes certainly come in a range of prices, from cheap to out of this world, and I am purely a duffer myself. But I enjoy looking at the moon and stars with magnification, and think they would, too. What I'm trying to find might be phrased like this: "the lowest priced scope that's reasonably robust, reasonably accurate, and reasonably usable for kids" -- meaning absolute precision is less important than a focus that is easy to set and doesn't drift. Simplicity in design beats tiny, ill-labeled parts or an incomprehensible manual, even if the complicated one might be slightly better when perfectly tuned. I'd be pleased if some of these kids decide to take up astronomy as a hobby, but don't have any strong expectation that will happen -- besides, if they really get into it, the research for a better one would be another fun project. That said, while I'm price sensitive, I'm not looking *only* at the price tag so much as seeking insight about the cluster of perceived sweet spots when it come to price / performance / personality. By "personality" I mean whether it's friendly, well documented, whether it comes intelligently packaged, whether it's a crapshoot as to whether a scope with the same model name will arrive in good shape, etc -- looking at online reviews, it seems many low-end scopes have a huge variance in reviews. What scopes would you would consider giving to an intelligent 3rd or 4th grader? As a starting point, Google has helped me find some interesting guides that list some scopes that sound reasonable, including a few under or near $100. (Here's one such set of suggestions.) What would you advise buying, from that list or otherwise? (There are some ideas that sound pretty good in this similar question from 2000, but I figure the state of the art has moved on.) I'm more interested in avoiding awful junk than I am expecting treasure: getting reasonable views of the moon is a good start, and getting at least some blurry rings around Saturn would be nice, too. Simply because they are so cheap, I'd like to know if anyone has impressions (worth it? pure junk?) of the Celestron FirstScope models, which are awfully tempting for under $50.

Spot ET's Waste Heat For Chance To Find Alien Life

slashdot.org - ds, 23/08/2014 - 23:21
mdsolar passes along this selection from New Scientist describing a (comparatively) low-tech means of scanning the skies for extraterrestrial civilizations: The best-known technique used to search for tech-savvy aliens is eavesdropping on their communications with each other. But this approach assumes ET is chatty in channels we can hear. The new approach, dubbed G-HAT for Glimpsing Heat from Alien Technologies, makes no assumptions about what alien civilisations may be like. "This approach is very different," says Franck Marchis at the SETI Institute in California, who was not involved in the project. "I like it because it doesn't put any constraints on the origin of the civilisation or their willingness to communicate." Instead, it utilises the laws of thermodynamics. All machines and living things give off heat, and that heat is visible as infrared radiation. The G-HAT team combed through the catalogue of images generated by the Wide-field Infrared Survey Explorer, or WISE, which released an infrared map of the entire sky in 2012. A galaxy should emit about 10 per cent of its light in the mid-infrared range, says team leader Jason Wright at Pennsylvania State University. If it gives off much more, it could be being warmed by vast networks of alien technology – though it could also be a sign of more prosaic processes, such as rapid star formation or an actively feeding black hole at the galaxy's centre.

Facebook Experimenting With Blu-ray As a Storage Medium

slashdot.org - ds, 23/08/2014 - 22:10
s122604 links to CNN's explanation of what may be the future of cold (or at least lukewarm) storage at Facebook, which is experimenting with massive arrays of Blu-Ray discs for seldom-accessed user files. Says the report: The discs are held in groups of 12 in locked cartridges and are extracted by a robotic arm whenever they're needed. One rack contains 10,000 discs, and is capable of storing a petabyte of data, or one million gigabytes. Blu-ray discs offer a number of advantages versus hard drives. For one thing, the discs are more resilient: they're water- and dust-resistant, and better able to withstand temperature swings. Their data can be restored more quickly, and they're easier to transport. Most important, though, is cost. Because the Blu-ray system doesn't need to be powered when the discs aren't in use, it uses 80% less power than the hard-drive arrangement, cutting overall costs in half.

The amount of money that Microsoft is keeping offshore represents a significant spike from prior years, and the levies the company would owe amount to almost the entire two-year operating budget of the company's home state of Washington."

The eruption of the Bardarbunga volcano in central Iceland, which appeared a strong possibility after a series of earthquakes, is currently underway, beneath the ice of the Dyngjujokull glacier. The BBC reports that Iceland has raised its air travel alert to red, its higest level, but that for now all of Iceland's airports remain open. CNN notes that "the underground activity did not immediately result in changes to volcanic activity on the surface ... Because of a pressure from the glacier cap it is uncertain whether the eruption will stay sub-glacial or not, Iceland 2 TV said."

Oregon Sues Oracle For "Abysmal" Healthcare Website

slashdot.org - ds, 23/08/2014 - 18:17
SpzToid (869795) writes The state of Oregon sued Oracle America Inc. and six of its top executives Friday, accusing the software giant of fraud for failing to deliver a working website for the Affordable Care Act program. The 126-page lawsuit claims Oracle has committed fraud, lies, and "a pattern of activity that has cost the State and Cover Oregon hundreds of millions of dollars". "Not only were Oracle's claims lies, Oracle's work was abysmal", the lawsuit said. Oregon paid Oracle about $240.3 million for a system that never worked, the suit said. "Today's lawsuit clearly explains how egregiously Oracle has disserved Oregonians and our state agencies", said Oregon Atty. Gen. Ellen Rosenblum in a written statement. "Over the course of our investigation, it became abundantly clear that Oracle repeatedly lied and defrauded the state. Through this legal action, we intend to make our state whole and make sure taxpayers aren't left holding the bag." Oregon's suit alleges that Oracle, the largest tech contractor working on the website, falsely convinced officials to buy "hundreds of millions of dollars of Oracle products and services that failed to perform as promised." It is seeking $200 million in damages. Oracle issued a statement saying the suit "is a desperate attempt to deflect blame from Cover Oregon and the governor for their failures to manage a complex IT project. The complaint is a fictional account of the Oregon Healthcare Project."
