Submission + - Location of mysterious Fast Radio Burst events pinpointed (bbc.com)

Netdoctor writes: Fast Radio Bursts (FRB) are massively powerful short-lived radio bursts from far-away sources, and so far a number of theories exist on what generates them. Recently several were detected in the same general location, which adds to the mystery, as any of these pulses would be powerful enough to destroy a source. Since this group of FRBs were detected with single radio telescope dishes, the exact location was difficult to pinpoint. BBC reports here with results from the Very Large Array in New Mexico being trained on the source.

Submission + - Ask Slashdot: Is Computing As Cool And Fun As It Once Was? 1

dryriver writes: I got together with old computer nerd friends the other day. All of us have been at it since the 8-bit / 1980s days of Amstrad, Atari, Commodore 64 type home computers. Everybody at the meeting agreed on one thing — computing is just not as cool and as much fun as it once was. One person lamented that computer games nowadays are tied to internet DRM like Steam, that some crucial DCC software is available to rent only now (e.g. Photoshop) and that many"basic freedoms" of the old-school computer nerd are increasingly disappearing. Another said that Windows 10's spyware aspects made him give up on his beloved PC platform and that he will use Linux and Android devices only from now on, using consoles to game on instead of a PC because of this. A third complained about zero privacy online, internet advertising, viruses, ransomware, hacking, crapware. I lamented that the hardware industry still hasn't given us anything resembling photorealistic realtime 3D graphics, and that the current VR trend arrived a full decade later than it should have. A point of general agreement was that big tech companies in particular don't treat computer users with enough respect anymore. What do Slashdotters think? Is computing still as cool and fun as it once was, or has something "become irreversibly lost" as computing evolved into a multi billion dollar global business?

Submission + - 6 mysterious radio signals have been detected coming from outside our galaxy (sciencealert.com)

schwit1 writes: Back in March, scientists detected 10 powerful bursts of radio signals coming from the same location in space. And now researchers have just picked up six more of the signals seemingly emanating from the same region, far beyond our Milky Way.

"We report on radio and X-ray observations of the only known repeating fast radio burst source, FRB 121102," the team wrote in The Astrophysical Journal.

"We have detected six additional radio bursts from this source: five with the Green Bank Telescope at 2 GHz, and one at 1.4 GHz with the Arecibo Observatory, for a total of 17 bursts from this source."

The team can't pinpoint the exact location of FRB 121102, but based on the specific way their lower frequencies are slowed, they can tell they came from a long way away, far beyond the Milky Way. And that gives us some pretty important clues about what could be causing the events.

Interestingly, it also contradicts the evidence we have on FRB coming from within our own galaxy.

Currently, the leading hypothesis for the source of the Milky Way's FRB is the cataclysmic collision of two neutron stars, which forms a black hole. The idea is that as this collision happens, huge amounts of short-lived radio energy are blasted out into space.

But the repeating nature of these distant signals, all coming from the same place, suggest that can't be the case — at least for these particular FRB.

Submission + - Verizon Refuses To Brick the Samsung Note 7 (theverge.com)

caferace writes: According to this article at The Verge, Verizon has refused to push out the Samsung "No-Charge" update.

"...Today, Samsung announced an update to the Galaxy Note 7 that would stop the smartphone from charging, rendering it useless unless attached to a power charger. Verizon will not be taking part in this update because of the added risk this could pose to Galaxy Note 7 users that do not have another device to switch to. We will not push a software upgrade that will eliminate the ability for the Note 7 to work as a mobile device in the heart of the holiday travel season. We do not want to make it impossible to contact family, first responders or medical professionals in an emergency situation.."

Submission + - Pebble ends production, ceases support (getpebble.com)

phorm writes: In a notice to Kickstarter backers, pebble has stated that — following the acquisition by Fitbit — they will no longer promote, manufacture, or sell devices. Further, while existing functionality may continue, it is likely to be degraded and warranty support will no longer be provided. This includes any recently shipped Pebble models. For those that were eagerly awaiting shipment of Pebble Time 2 and other newer devices, those devices will not ship at all. Pebble has indicated refunds will be made within 4-8 weeks. Those expecting their money may not want to hold their breath, however, because a contradictory statement made by to backers by email says that refunds will be made via Kickstarter by March 2017.

Submission + - Level 3 under DDOS (chicagotribune.com)

Archangel Michael writes: From The Linked Article:

Parts of the internet were down across the U.S. and in the U.K. Wednesday morning, as service provider Level 3 Communications reported an outage.

Level 3, which provides internet and voice services to businesses, said the company did not yet know the cause of the outage, which temporarily disrupted or slowed service to some customers.

"Our technical team is looking into this issue to determine the cause. Our priority is to ensure the reliability of our network and services. We will provide updates as more information becomes available," Nikki Wheeler, senior director of media relations, wrote in an email.

Submission + - Strange signals from star survey may be evidence of intelligent life (iop.org)

Okian Warrior writes: A recent paper reporting on strange artifacts in the spectra of 234 stars is raising eyebrows in the Astronomical community.

A Fourier transform analysis of 2.5 million spectra in the Sloan Digital Sky Survey was carried out to detect periodic spectral modulations. Signals having the same period were found in only 234 stars overwhelmingly in the F2 to K1 spectral range. The signals cannot be caused by instrumental or data analysis effects because [various reasons...]

Finally, we consider the possibility, predicted in a previous published paper, that the signals are caused by light pulses generated by ETI to makes us aware of their existence. We find that the detected signals have exactly the shape of an ETI signal predicted in the previous publication and are therefore in agreement with this hypothesis. The fact that they are only found in a very small fraction of stars within a narrow spectral range centered near the spectral type of the Sun is also in agreement with the ETI hypothesis. However, at this stage, this hypothesis needs to be confirmed with further work.


Submission + - "Most serious" Linux privilege-escalation bug ever is under active exploit (arstechnica.com)

operator_error writes: Lurking in the kernel for nine years, flaw gives untrusted users unfettered root access.

By Dan Goodin — 10/20/2016

A serious vulnerability that has been present for nine years in virtually all versions of the Linux operating system is under active exploit, according to researchers who are advising users to install a patch as soon as possible.

While CVE-2016-5195, as the bug is cataloged, amounts to a mere privilege-escalation vulnerability rather than a more serious code-execution vulnerability, there are several reasons many researchers are taking it extremely seriously. For one thing, it's not hard to develop exploits that work reliably. For another, the flaw is located in a section of the Linux kernel that's a part of virtually every distribution of the open-source OS released for almost a decade. What's more, researchers have discovered attack code that indicates the vulnerability is being actively and maliciously exploited in the wild.

"It's probably the most serious Linux local privilege escalation ever," Dan Rosenberg, a senior researcher at Azimuth Security, told Ars. "The nature of the vulnerability lends itself to extremely reliable exploitation. This vulnerability has been present for nine years, which is an extremely long period of time."

The underlying bug was patched this week by the maintainers of the official Linux kernel. Downstream distributors are in the process of releasing updates that incorporate the fix. Red Hat has classified the vulnerability as "important."

Submission + - First New US Nuclear Reactor In 20 Years Goes Live (cnn.com)

An anonymous reader writes: The Tennessee Valley Authority is celebrating an event 43 years in the making: the completion of the Watts Bar Nuclear Plant. In 1973, the TVA, one of the nation's largest public power providers, began building two reactors that combined promised to generate enough power to light up 1.3 million homes. The first reactor, delayed by design flaws, eventually went live in 1996. Now, after billions of dollars in budget overruns, the second reactor has finally started sending power to homes and businesses. Standing in front of both reactors Wednesday, TVA President Bill Johnson said Watts Bar 2, the first US reactor to enter commercial operation in 20 years, would offer clean, cheap and reliable energy to residents of several southern states for at least another generation. Before Watts Bar 2, the last time an American reactor had fired up was in 1996. It was Watts Bar 1--and according to the Atlanta Journal-Constitution, it cost $6.8 billion, far greater than the original price tag at $370 million. In the 2000s, some American power companies, faced with growing environmental regulations, eyed nuclear power again as a top alternative to fossil fuels such as coal and oil. A handful of companies, taking advantage of federal loan guarantees from the Bush administration, revived nuclear reactor proposals in a period now known as the so-called "nuclear renaissance." Eventually, nuclear regulators started to green light new reactors, including ones in Georgia and South Carolina. In 2007, the TVA resumed construction on Watts Bar 2, according to the International Atomic Energy Agency. The TVA originally said it would take five years to complete. The TVA, which today serves seven different southern states, relies on nuclear power to light up approximately 4.5 million homes. Watts Bar 2, the company's seventh operating reactor, reaffirms its commitment to nukes for at least four more decades, Johnson said Wednesday. In the end, TVA required more than five years to build the project. The final cost, far exceeding its initial budget, stood at $4.7 billion.

Submission + - U.S. Officially Accuses Russia of Election Hacks

wiredmikey writes: The U.S. government has officially accused Russia of being behind cyberattacks against American political organizations with the intent of interfering with the upcoming Presidential election in November.

“The U.S. Intelligence Community (USIC) is confident that the Russian Government directed the recent compromises of e-mails from US persons and institutions, including from US political organizations,” a joint statement from the Department of Homeland Security (DHS) and Office of the Director of National Intelligence said.

"We believe, based on the scope and sensitivity of these efforts, that only Russia's senior-most officials could have authorized these activities," the statement adds.

In August, researchers from two security firms uncovered evidence that they say linked a Russian threat actor to the cyberattack targeting the U.S. Democratic Congressional Campaign Committee (DCCC).

Submission + - Multiple Linux Distributions Affected by Crippling Bug in systemd (agwa.name) 1

An anonymous reader writes: System administrator Andrew Ayer has discovered a potentially critical bug in systemd which can bring a vulnerable Linux server to its knees with one command. "After running this command, PID 1 is hung in the pause system call. You can no longer start and stop daemons. inetd-style services no longer accept connections. You cannot cleanly reboot the system." According to the bug report, Debian, Ubuntu, and CentOS are among the distros susceptible to various levels of resource exhaustion. The bug, which has existed for more than two years, does not require root access to exploit.

Submission + - What is employers obsession with programming languages? 1

An anonymous reader writes: Just got off the phone with a recruiter for a company and the lady asked if I had 3-4 years C++ and 3-4 years Java experience. Okay, so first off, C++ and Java are two different programming languages used for two completely different purposes.

C++ being used mainly for low-level platform specific programming and Java being platform independent. My response was I programmed in C++ throughout college, but haven't worked any jobs specifically writing C++ and I've had Java experience in past jobs, but mostly used C# which was similar.

She said, "Oh well we are only looking for those two languages so thanks anyways". Is it just me or is this absolutely insane? It's like wanting to hire a mechanic who has 3-4 years experience working with just 1978 ford trucks. I mean really? How did we get to this point as engineers?

As any developer worth their weight in salt can attest, the languages are so similar it's kind of difficult to distinguish between them looking at syntax alone and if you've got a computer science background or equiv what's it really matter if the underlying OOP concepts are the same.

Is this just a result of incompetent managers and ignorant recruiters or as engineers have we set ourselves up by succumbing to a label such as Java Engineer or C# Programmer.

Should I just say yes, and move forward with the interview? I mean, I could probably answer most C++/Java programming questions unless they are truly looking for people who spend all their time memorizing specific libraries or API's which in my opinion is insane. I equate that to trying to memorize a phone book. You can but why would you want to?

Not only is it frustrating as a job candidate, but it seems to really be limiting your hiring pool to a small few who by chance happen to work in a couple different programming languages over the course of their career. How do most of you handle this sort of thing?
