Outlining Thin Linux 221

Posted by Soulskill from the tux-on-a-diet dept.
snydeq writes: Deep End's Paul Venezia follows up his call for splitting Linux distros in two by arguing that the new shape of the Linux server is thin, light, and fine-tuned to a single purpose. "Those of us who build and maintain large-scale Linux infrastructures would be happy to see a highly specific, highly stable mainstream distro that had no desktop package or dependency support whatsoever, so was not beholden to architectural changes made due to desktop package requirements. When you're rolling out a few hundred Linux VMs locally, in the cloud, or both, you won't manually log into them, much less need any type of graphical support. Frankly, you could lose the framebuffer too; it wouldn't matter unless you were running certain tests," Venezia writes. "It's only a matter of time before a Linux distribution that caters solely to these considerations becomes mainstream and is offered alongside more traditional distributions."

Service Promises To Leak Your Documents If the Government Murders You 98

Posted by samzenpus from the if-anything-happens-to-me dept.
Jason Koebler writes With all the conspiracy theories surrounding some high-profile deaths in recent years, how can you, theoretical whistleblower with highly sensitive documents, be assured that your information gets leaked if you're murdered in some government conspiracy? A new dark web service says it's got your back. "Dead Man Zero" claims to offer potential whistleblowers a bit more peace of mind by providing a system that will automatically publish and distribute their secrets should they die, get jailed, or get injured.

Apple Sells More Than 10 Million New iPhones In First 3 Days 206

Posted by samzenpus from the get-it-now dept.
An anonymous reader writes Apple has announced that it sold over 10 million new iPhone 6 and iPhone 6 Plus models, just three days after the launch on September 19. From the article: "Chief Executive Tim Cook said the company could have sold even more iPhone 6 and iPhone 6 Plus models if supplies had been available. Analysts had estimated first-weekend sales of up to 10 million iPhones, after Apple booked record pre-orders of 4 million on Sept. 12, the day pre-orders opened."

"Big Bang Signal" Could All Be Dust 133

Posted by samzenpus from the not-so-fast dept.
An anonymous reader writes Scientists have shown that the swirl pattern touted as evidence of primordial gravitational waves — ripples in space and time dating to the universe's explosive birth — could instead all come from magnetically aligned dust. A new analysis of data from the Planck space telescope has concluded that the tiny silicate and carbonate particles spewed into interstellar space by dying stars could account for as much as 100 percent of the signal detected by the BICEP2 telescope and announced to great fanfare this spring. The Planck analysis is "relatively definitive in that we can't exclude that the entirety of our signal is from dust," said Brian Keating, an astrophysicist at the University of California, San Diego, and a member of the BICEP2 collaboration.

Comment Attacker is your Peer (Score 4, Insightful) 85

Except "Attacker" in this case is the administrator at the peer, and the peers are entire companies, multinationals, and governments. We're not talking about your average basement-dweller script kiddie.

If your peers are messing with you, or their peers are messing with them, how do you defend against an attack where the whole system is based on trust?

You could go to a no-trust solution, but then that would need a central authority that would need to pre-calculate all the routes from every single AS. If a route breaks, that'll be slow to adjust to a backup route. If a new route needs to be added, the ISP would need to apply to a central authority with bureaucracy and red tape.

If a route needed to be blackholed because of a DDOS, and that action had to be approved of by a central authority, which could take days to weeks for a ruling, nothing could be done because routers would not accept changes to any route until then.

Essentially, the answer to security is to effectively lock out the AS ISPs from their own routers.

You either trust the AS administrators or you don't. And since they're humans, they'll make mistakes, be malicious, or be affected by politics. This won't be solved by (trusting) a central bureaucracy similar to the UN, at least not in a manner you'll prefer.

UCLA, CIsco & More Launch Consortium To Replace TCP/IP 254

Posted by timothy from the still-involves-controls-and-protocols dept.
alphadogg writes Big name academic and vendor organizations have unveiled a consortium this week that's pushing Named Data Networking (NDN), an emerging Internet architecture designed to better accommodate data and application access in an increasingly mobile world. The Named Data Networking Consortium members, which include universities such as UCLA and China's Tsinghua University as well as vendors such as Cisco and VeriSign, are meeting this week at a two-day workshop at UCLA to discuss NDN's promise for scientific research. Big data, eHealth and climate research are among the application areas on the table. The NDN effort has been backed in large part by the National Science Foundation, which has put more than $13.5 million into it since 2010.

Slashdot Asks: Cheap But Reasonable Telescopes for Kids? 187

Posted by timothy from the will-take-credit-for-the-nobel-prize dept.
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.

It's Dumb To Tell Kids They're Smart 243

Posted by timothy from the converse-is-also-true dept.
theodp writes Over at Khan Academy, Salman Khan explains Why I'm Cautious About Telling My Son He's Smart. "Recently," writes Khan, "I put into practice research I had been reading about for the past few years: I decided to praise my son not when he succeeded at things he was already good at, but when he persevered with things that he found difficult. I stressed to him that by struggling, your brain grows. Between the deep body of research on the field of learning mindsets and this personal experience with my son, I am more convinced than ever that mindsets toward learning could matter more than anything else we teach." According to Dr. Carol Dweck, who Khan cites, the secret to raising smart kids is not telling kids that they are. A focus on effort — not on intelligence or ability — says Dweck, is key to success in school and in life.

New EU Rules Will Limit Vacuum Cleaners To 1600W 338

Posted by timothy from the sucking-power-defined dept.
AmiMoJo writes "New EU rules are limiting vacuum cleaner motors to 1600W from 2014/09/01. The EU summary of the new rules explains that consumers currently equate watts with cleaning power, which is not the case. Manufacturers will be required to put ratings on packaging, including energy efficiency, cleaning efficiency on hard and carpeted floors, and dust emissions from the exhaust. In the EU vacuum cleaners use more energy than the whole of Denmark, and produce more emissions than dishwashers and washing machines."

10 years ago, there were regularly 800-1000 comments on articles. Now, a highly commented article gets around 200.

It's a shame that the editors have stopped doing their jobs and post anything without checking it (at best!). But this isn't the first time I've seen it.

This submission is obviously false, and it needs to be pulled down or with the inflammatory and false sentence deleted. Since it's been up for hours, and there are numerous posts above that debunk the submission, it leads me to believe that Slashdot wants the clickbait and is leaving it up on purpose.

Do the right thing. Pull the article. Save what's left of your reputation, Slashdot.
