Ask Slashdot: What's the Harm In a Default Setting For Div By Zero? 1067

Posted by timothy from the as-long-as-it's-a-big-zero dept.
New submitter CodeInspired writes: After 20 years of programming, I've decided I'm tired of checking for div by zero. Would there be any serious harm in allowing a system wide setting that said div by zero simply equals zero? Maybe it exists already, not sure. But I run into it all the time in every language I've worked with. Does anyone want their div by zero errors to result in anything other than zero?

Surface Pro 3 Handily Outperforms iPad Air 2 and Nexus 9 204

Posted by timothy from the but-can-it-take-pictures dept.
An anonymous reader points to an interesting comparison of current tablets' peformance, as measured with the Geekbench benchmarking tool, which boils down various aspects of performance to produce a single number. The clear winner from the models fielded wasn't from Apple of Samsung (Samsung's entrants came much lower down, in fact), but from Microsoft: the i5-equipped Surface Pro 3, with a Geekbench score of 5069.; second place goes to the Apple iPad Air 2, with 4046. The Nexus 9 rated third, with 3537. One model on the list that U.S. buyers may not be familiar with is the Tesco Hudl 2, a bargain tablet which Trusted Reviews seems quite taken by.

Microsoft Research Paper Considers Serving Web-ads From Localhost 231

Posted by timothy from the call-is-coming-from-inside-the-house dept.
An anonymous reader writes: A paper from Microsoft researchers (PDF) posits the possibility of 'pushing' web ads to a user's own computer and serving them into pre-arranged containers on web pages, with the EFF or ACLU serving as privacy mediators between the user and the advertisers who want to engage them. However the framework — dubbed 'Privad' — would need to get installed on the user's system by the same familiar means which the likes of Superfish use. The report admits that Privad would probably need to be disseminated "through adware-style software bundling, shopping discounts, toolbars or other incentives."

Ask Slashdot: What Hardware Is In Your Primary Computer? 558

Posted by Soulskill from the very-bored-hamsters dept.
An anonymous reader writes: Here's something we haven't done in a while: list the specs of your main system (best one) so we can see what kinds of computers Slashdot geeks use. Context would be interesting, too — if you're up for it, explain how and why you set it up as you did, as well as the computer's primary purpose(s). Things you can list include (but are not limited to): CPU, motherboard, video card, memory, storage (SSD/HDD), exotic Controllers (RAID or caching), optical drives, displays, peripherals, etc. We can compare and contrast, see what specs are suitable for what purposes, and perhaps learn a trick or two.

Facebook Sued In US Court For Blocking Page In India 100

Posted by timothy from the proper-jurisdiction dept.
itwbennett writes: Facebook has been sued in California by the non-profit organization Sikhs For Justice for blocking their page in India. The group has charged Facebook with engaging in 'a pattern of civil rights violation and blatant discriminatory conduct' by blocking its content in the whole of India. It has asked the court for a permanent injunction on further blocking of the page, access to Facebook's correspondence with the Indian government about the block, and an award of damages, besides other relief.

Why PowerPoint Should Be Banned 327

Posted by Soulskill from the hang-on-my-clicker-isn't-working dept.
An anonymous reader writes: An editorial at the Washington Post argues that Microsoft PowerPoint is being relied upon by too many to do too much, and we should start working to get rid of it. "Its slides are oversimplified, and bullet points omit the complexities of nearly any issue. The slides are designed to skip the learning process, which — when it works — involves dialogue, eye-to-eye contact and discussions. Of course PowerPoint has merits — it can help businesses with their sales pitches or let teachers introduce technology into the classroom. But instead of being used as a means for a dynamic engagement, it has become a poor substitute for longer, well-thought-out briefings and technical reports. It has become a crutch."

Rand Paul Moves To Block New "Net Neutrality" Rules 438

Posted by samzenpus from the won't-somebody-please-think-of-the-isps? dept.
SonicSpike writes with news about another bump in the road for net neutrality. U.S. Senator Rand Paul, a Republican presidential hopeful, on Wednesday introduced a resolution to block new regulations on Internet service providers, saying they would 'wrap the Internet in red tape.' The 'net neutrality' rules, which are slated to take effect in June, are backed by the Obama administration and were passed by the Democratic majority of the Federal Communications Commission in February. AT&T Inc and wireless and cable trade associations are challenging them in court. Paul's resolution, if adopted, would allow the Senate to fast-track a vote to establish that Congress disapproves of the FCC's new rules and moves to nullify them.

Microsoft, Chip Makers Working On Hardware DRM For Windows 10 PCs 304

Posted by Soulskill from the just-what-users-wanted dept.
writertype writes: Last month, Microsoft began talking about PlayReady 3.0, which adds hardware DRM to secure 4K movies. Intel, AMD, Nvidia, and Qualcomm are all building it in, according to Microsoft. "Older generations of PCs used software-based DRM technology. The new hardware-based technology will know who you are, what rights your PC has, and won’t ever allow your PC to unlock the content so it can be ripped. ... Unfortunately, it looks like the advent of PlayReady 3.0 could leave older PCs in the lurch. Previous PlayReady technology secured content up to 1080p resolution using software DRM—and that could be the maximum resolution for older PCs without PlayReady 3.0." Years back, a number of people got upset when Hollywood talked about locking down "our content." It looks like we may be facing it again for 4K video.

Update: No Personhood for Chimps Yet 336

Posted by timothy from the do-you-have-standing dept.
sciencehabit writes: In a decision that effectively recognizes chimpanzees as legal persons for the first time, a New York judge [Monday] granted a pair of Stony Brook University lab animals the right to have their day in court. The ruling marks the first time in U.S. history that an animal has been covered by a writ of habeus corpus, which typically allows human prisoners to challenge their detention. The judicial action could force the university, which is believed to be holding the chimps, to release the primates, and could sway additional judges to do the same with other research animals. Update: 04/21 21:39 GMT by S : Science has updated their article with news that the court has released an amended order (PDF) with the words "writ of habeas corpus" removed, no longer implying that chimps have legal personhood. The order still allows the litigation to go forward, but we'll have to wait for resolution.

Automakers To Gearheads: Stop Repairing Cars 649

Posted by samzenpus from the put-down-the-wrench-and-back-away dept.
Mr_Blank writes Automakers are supporting provisions in copyright law that could prohibit home mechanics and car enthusiasts from repairing and modifying their own vehicles. In comments filed with a federal agency that will determine whether tinkering with a car constitutes a copyright violation, OEMs and their main lobbying organization say cars have become too complex and dangerous for consumers and third parties to handle. The dispute arises from a section of the Digital Millennium Copyright Act that no one thought could apply to vehicles when it was signed into law in 1998. But now, in an era where cars are rolling computing platforms, the U.S. Copyright Office is examining whether provisions of the law that protect intellectual property should prohibit people from modifying and tuning their cars.

Ask Slashdot: Best Medium For Storing Data To Survive a Fire (or Other Disaster) 446

Posted by samzenpus from the burning-down-the-house dept.
First time accepted submitter aka_bigred writes Every year as I file my taxes, I replicate my most important financial data (a couple GB of data) to store an offline copy in my fire-rated home safe. This gets me thinking about what the most reliable data media would be to keep in my fire-rated home safe.

CDs/DVDs/tapes could easily melt or warp rendering them useless, so I'm very hesitant to use them. I've seen more exotic solutions that let you print your digital data to paper an optically re-import it later should you ever need it, but it seems overly cumbersome and error prone should it be damaged or fire scorched. That leaves my best options being either a classic magnetic platter drive, or some sort of solid state storage, like SD cards, USB flash drives, or a small SSD. The problem is, I can't decide which would survive better if ever exposed to extreme temperatures, or water damage should my house burn down.

Most people would just suggest to store it in "the cloud", but I'm naturally averse to doing so because that means someone else is responsible for my data and I could lose it to hackers, the entity going out of business, etc. Once it leaves my home, I no longer fully control it, which is unacceptable. My thought being "they can't hack/steal what they can't physically access." What medium do other Slashdot users use to store their most important data (under say 5GB worth) in an at-home safe to protect it from fire?

Supernovae May Not Be Standard Candles; Is Dark Energy All Wrong? 199

Posted by Soulskill from the either-that-or-it-isn't dept.
StartsWithABang writes: The accelerated expansion of the Universe — and hence, dark energy — was discovered by taking the well-understood phenomenon of type Ia supernovae and measuring them out to great distances. The results indicated that they were fainter than expected, and hence more distant, and hence the Universe's expansion must be accelerating. But new results have just come out, showing that supernovae may not be standard after all. Does this mean dark energy may not be real, or that it may just be slightly weaker than we previously thought?

Cannabis Smoking Makes Students Less Likely To Pass University Courses 291

Posted by Soulskill from the killing-your-buzz dept.
Bruce66423 writes: A large scale European study shows that students who were unable to buy cannabis legally were 5% more likely to pass their University courses. Below-average students with no legal access to pot were 7.6% more likely to pass their courses, and the effect was five times more pronounced when dealing with courses involving math. One of the study's authors said, "We think this newfound effect on productivity from a change in legal access to cannabis is not negligible and should be, at least in the short run, politically relevant for any societal drug legalization and prohibition decision-making. In the bigger picture, our findings also indicate that soft drug consumption behavior is affected by their legal accessibility, which has not been causally demonstrated before. ... Considering the massive impact on cognitive performance high levels of THC have, I think it is reasonable to at least inform young users much more on consequences of consuming such products as compared with that of having a beer or pure vodka."

You wouldn't NEED to hack into it (although it is certainly a legitimate vector). Less technical "terrorists" could simply use enough force to take over a tower or control center and send commands from an authorized terminal (likely with an authorized ID gotten by the "rubber hose" method). You would then be able to proceed to down any planes in the control area of that tower. I think I would rather have the smarts controlling the plane (whether it be computer or pilot controlled) on the plane with outside access limited to when it is requested by at least a couple of members of the flight crew.
