Lies, Damned Lies and Cat Statistics 175

spopepro writes "While un-captioned cats might be of limited interest to the /. community, I found this column on how a fabricated statistic takes on a life of its own interesting. Starting with the Humane Society of the United States' (HSUS) claim that the unsterilized offspring of a cat will '...result in 420,000 cats in 5 years,' the author looks at other erroneous numbers, where they came from and why they won't go away."

Comment Re:Another vote for NoSQL and some experience (Score 1) 235

I have seen these kinds of situations happen a lot (I'm a statistician who works on computationally-intensive physical science applications), and the best solution I have seen was a BerkeleyDB setup. One group I work with had a very, very large number of ASCII data files (order of 10-100 million) in a directory tree. One of their researchers consolidated them to a BerkeleyDB, which greatly improved data management and access [...] I think the general idea of a key-value store that lets you keep your data in the original structure would work well.

A file system *is* a key-value store.

I suspect those 100,000,000 files were in fact tiny pieces of data which didn't make sense to access using normal tools (from ls to MS Word). That the conversion worked out for *you* doesn't mean that it would be useful to convert *every* set of files into a BerkeleyDB. Especially not sets of (say) 500 files, 10GB each.

I completely agree. If you have a lot of small datasets that break ls and such (as was the case in my situation), BerkeleyDB provided a great solution. If you have a smaller set of very large files, a different solution is needed (perhaps just the file system with some kind of automated indexing).

How Do I Get Open Source Programs Written For Me? 285

An anonymous reader writes "I am a biomedical researcher interested in having general-purpose, scientific programs developed and released as open source. Interface design and reusability of the code are of primary importance to me. For my purpose, Cocoa applications relying on Core Data seem to be the best way to get the job done quickly. While I have some programming experience, I have few connections to the industrial world. So my question to Slashdot readers is: how do I find someone (individual or business) to write high-quality programs? Are there reputable contractors experienced in Cocoa? What sort of rates should I expect, to use as a starting point in negotiations? Would a requirement that programs are released as open source make it more or less difficult to find someone to do the job?"

Small Asteroid On Collision Course With Earth 397

musatov writes "There's talk on The Minor Planet Mailing List about a small asteroid approaching Earth with a 99.8% probability of colliding. The entrance to the Earth's atmosphere will take place October 7 at 0246 UTC (2:35 after this story goes live) over northern Sudan, releasing the energy of about a kiloton of TNT. The asteroid is assumed to be 3-4 meters in size; it is expected to burn up completely in the atmosphere, causing no harm. As a powerful bolide, it may put on quite a show in the sky. For those advanced enough in astronomy to observe, check the MPEC 2008-T50 and MPEC 2008-T64 circulars. NASA's JPL Small Body Database has a 3D orbit view. The story has been already picked up by CNN and NASA."

Nobel Prize For Medicine Awarded, Physics Soon To Follow 135

Nobel Prize season is here again, and the first award for Physiology or Medicine was split between two virologists who discovered HIV and one who demonstrated that a virus causes cervical cancer. Coming soon is the announcement for Physics. Look to the right for a chance to pit your selection wit against the Royal Swedish Academy of Sciences with a poll for which scientific achievement deserves the prize. Front runners, according to Reuters, are; Andre Geim and Kostya Novoselov, discovers of graphene, Vera Rubin, provider of the best evidence yet of dark matter, and Roger Penrose and Dan Shechtman, discoverers of Penrose tilings and quasicrystals.

On Fourth Launch Attempt, SpaceX Falcon 1 Reaches Orbit 518

xp65 writes with the just-announced success of Elon Musk's SpaceX's long efforts to reach orbit with a privately-developed launching craft: "T+0:08:21 Falcon 1 reached orbital velocity, 5200 m/s Nominal Second stage cut off (SECO) — Falcon 1 has made history as the first privately developed liquid fueled launch vehicle to achieve earth orbit!" dbullard adds "This was a completely new vehicle — it's not using any previously developed hardware. All developed from scratch. No government supplied hardware, Russian engines, or old ICBM motors. My hat's off to the employees of Space X — all 550 of them. (Note — no 'cast of thousands,' just 550). They've got video of the entire launch."

Wall Street's Collapse Is Computer Science's Gain 435

dcblogs writes "Thanks to Wall Street's implosion, the chairman of Stanford University's Computer Science Department says he is seeing more interest from students in computer science. Ditto at Boston College. Computer science enrollments crashed after the dot-com bust as students turned to hedge fund majors. And are computer science grads getting jobs? The professor at one university program that graduates about 45 students a year with CS degrees, wrote in a comment: 'Last year 87% of our seniors were employed before graduation. The median starting salary was $58,500. A majority of CIS students had multiple job offers. From where I sit, there is a huge demand for entry level IT professionals in IS and in CS.'"

NYT Ponders the Future of Solaris In a Linux/Windows World 340

JerkBoB links to a story at the New York Times about the future prospects of Sun's Solaris, excerpting: "Linux is enjoying growth, with a contingent of devotees too large to be called a cult following at this point. Solaris, meanwhile, has thrived as a longstanding, primary Unix platform geared to enterprises. But with Linux the object of all the buzz in the industry, can Sun's rival Solaris Unix OS hang on, or is it destined to be displaced by Linux altogether?"

Microsoft Blesses LGPL, Joins Apache Foundation 425

Penguinisto writes "According to a somewhat jaw-dropping story in The Register, it appears that Microsoft has performed a trifecta of geek-scaring feats: They have joined the Apache Software Foundation as a Platinum member(at $100K USD a year), submitted LGPL-licensed patches for ADOdb, and have pledged to expand their Open Specifications Promise by adding to the list more than 100 protocols for interoperability between its Windows Server and the Windows client. While I sincerely doubt they'll release Vista under a GPL license anytime soon, this is certainly an unexpected series of moves on their part, and could possibly lead to more OSS (as opposed to 'Shared Source') interactivity between what is arguably Linux' greatest adversary and the Open Source community." (We mentioned the announced support for the Apache Foundation earlier today, as well.)

Amazon Insists Publishers Use Their On-Demand Printer 182

Lawrence Person writes "According to a story up on Writer's Weekly, Print on Demand publishers are being told to use Amazon's own BookSurge POD printer or else Amazon will disable the 'buy' button for their books. After hemming and hawing, an Amazon/BookSurge rep 'finally admitted that books not converted to BookSurge would have the "buy" button turned off on Amazon.com, just as we'd heard from several other POD publishers who had similar conversations with Amazon/BookSurge representatives... their eventual desire is to have no books from other POD publishers available on Amazon.com.' So much for Amazon's Vision Statement: 'Our vision is to be earth's most customer centric company; to build a place where people can come to find and discover anything they might want to buy online.'"

The Reality Distortion Field Is Real 270

TimeZone writes "Apparently, even subliminal exposure to the Apple logo can make you 'think different.' Researchers at Duke University subjected participants to subliminal images of the iconic Apple and IBM logos (during what subjects thought was a visual acuity test), and those who were shown the Apple logo generated more creative ideas after the test than did those who were shown the IBM logo. In a second test, subjects exposed to the Disney logo acted more honestly than those who saw an E! Channel logo." Here's a preprint of the paper (PDF) due for publication in the Journal of Consumer Research.

Creationism Museum Opening in Kentucky 1166

Noel Linback writes "A new creationism-espousing museum is opening in the state of Kentucky. According to a New York Times article the museum depicts humans and dinosaurs living together in traditional 'diorama' style exhibit. 'Whether you are willing to grant the premises of this museum almost becomes irrelevant as you are drawn into its mixture of spectacle and narrative. Its 60,000 square feet of exhibits are often stunningly designed by Patrick Marsh, who, like the entire museum staff, declares adherence to the ministry's views; he evidently also knows the lure of secular sensations, since he designed the Jaws and King Kong attractions at Universal Studios in Florida. For the skeptic the wonder is at a strange universe shaped by elaborate arguments, strong convictions and intermittent invocations of scientific principle. For the believer, it seems, this museum provides a kind of relief: Finally the world is being shown as it really is, without the distortions of secularism and natural selection. '"

Two Ways Not To Handle Free Speech 686

Two stories in the news offer contrasting approaches by Web companies to questions of free speech. First YouTube: reader skraps notes that the Google property has recently banned the popular atheist commentator Nick Gisburne. Gisburne had been posting videos with logical arguments against Christian beliefs; but when he turned his attention to Islam (mirror of Gisburne's video by another user), YouTube pulled the plug, saying: 'After being flagged by members of the YouTube community, and reviewed by YouTube staff, the video below has been removed due to its inappropriate nature. Due to your repeated attempts to upload inappropriate videos, your account now been permanently disabled, and your videos have been taken down.' Amazon.com provides a second example of how to react to questions of free speech. Reader theodp sends along a story in TheStreet.com about how Amazon hung up on customers wanting to comment on its continuing practice of selling animal-fighting magazines. The article notes that issues of free speech are rarely cut-and-dried, and that Amazon is doing itself no favors by going up against the Humane Society.
