The Performance of Ubuntu Linux Over the Past 10 Years (phoronix.com) 101

An anonymous reader writes: Tests were carried out at Phoronix of all Ubuntu Long-Term Support releases from the 6.06 "Dapper Drake" release to 16.04 "Xenial Xerus," looking at the long-term performance of (Ubuntu) Linux using a dual-socket AMD Opteron server. Their benchmarks of Ubuntu's LTS releases over 10 years found that the Radeon graphics performance improved substantially, the disk performance was similar while taking into account the switch from EXT3 to EXT4, and that the CPU performance had overall improved for many workloads thanks to the continued evolution of the GCC compiler.

Ethics Panel Endorses Mitochondrial Therapy, But Says Start With Male Embryos (sciencemag.org) 124

sciencehabit writes: An experimental assisted reproduction technique that could allow some families to avoid having children with certain types of heritable disease should be allowed to go forward in the United States, provided it proceeds slowly and cautiously. That is the conclusion of a report released today from a panel organized by the U.S. National Academies of Sciences, Engineering, and Medicine (NAS), which assesses the ethics questions surrounding the controversial technique called mitochondrial DNA replacement therapy. More controversially, however, the panel recommended that only altered male embryos should be used to attempt a pregnancy, to limit the possible risks to future generations. (Males can't pass along the mitochondrial DNA that is altered in the procedure.)

LG G3 'Snap' Vulnerability Leaves Owners At Risk of Data Theft (betanews.com) 39

Mark Wilson writes: Security researchers have discovered a vulnerability in LG G3 smartphones which could be exploited to run arbitrary JavaScript to steal data. The issue has been named Snap, and was discovered by Israeli security firms BugSec and Cynet. What is particularly concerning about Snap is that it affects the Smart Notice which is installed on all LG G3s by default. By embedding malicious script in a contact, it is possible to use WebView to run server side code via JavaScript. If exploited, the vulnerability could be used to gather information from SD cards, steal data from the likes of WhatsApp, and steal private photos.

Serious Linux Kernel Vulnerability Patched (threatpost.com) 85

msm1267 writes: A patch for a critical Linux kernel flaw, present in the code since 2012, is expected to be pushed out today. The vulnerability affects versions 3.8 and higher, said researchers at startup Perception Point who discovered the vulnerability. The flaw also extends to two-thirds of Android devices, the company added. An attacker would require local access to exploit the vulnerability on a Linux server. A malicious mobile app would get the job done on an Android device. The vulnerability is a reference leak that lives in the keyring facility built into the various flavors of Linux. The keyring encrypts and stores login information, encryption keys and certificates, and makes them available to applications. Here's Perception Point's explanation of the problem.

They are probably waiting for the price to go up. There are wells all over the Midwest that have been prepped for drilling but not drilled, or drilled but not fracked, or fracked but are being held idle, because the economics of their existence was calculated on $80+/barrel oil. The companies are letting them sit hoping the price goes up so they can make more. It's easy to project how long this is worth doing given a certain amount of volatility in the price and the fact that demand will always be there, in fact, the current glut of NG in North America means applications are being converted to run NG, possibly boosting the coming price upswing.

Comment Re:Squaring up photos of pages (Score 1) 122

If you scan the pages in batches consistently, the crop and rotate parameters will be the same for all the pages in a batch. Then you just have to tweak the parameters once per batch. If you use a tripod and don't bump the camera, the batches can be big.

I wrote a script to do this exact thing. You put the crop, rotate, etc. parameters into a text file which you can save along with the batch of images. It also supports multicropping each image so that you can use it to build indexes of negative and slide pages, which is why I really wrote it. I can take pictures of dozens of Printfile pages of slides or negatives and auto-crop out the individual images to build an index of low-res images for browsing. I also use it for batch - scanning photo prints at full resolution and just trim the edges off,fix slight rotating etc.

The IM crop command basically does all the work. It is a very powerful program.

Rural Mississippi: The Land That the Internet Era Forgot (wired.com) 154

New submitter lesedeuezghe writes with this Wired story by W. Ralph Eubanks about the efforts of the Extension Service to broaden its scope from mostly agricultural information to bringing broadband to rural communities. "In sleepy public libraries, at Rotary breakfasts, and in town halls, he [Assistant Extension Professor Roberto Gallardo] gives PowerPoint presentations that seem calculated to fill rural audiences with healthy awe for the technological sublime. Rather than go easy, he starts with a rapid-fire primer on heady concepts like the Internet of Things, the mobile revolution, cloud computing, digital disruption, and the perpetual increase of processing power. ('It’s exponential, folks. It’s just growing and growing.') The upshot: If you don’t at least try to think digitally, the digital economy will disrupt you. It will drain your town of young people and leave your business in the dust. Then he switches gears and tries to stiffen their spines with confidence. Start a website, he’ll say. Get on social media. See if the place where you live can finally get a high-speed broadband connection—a baseline point of entry into modern economic and civic life."

I use LaTeX reports on a webserver instead of a paper lab notebook. One, I can't lose it. Two, paper is filthy and I work in a cleanroom. In the lab I am never far from a computer with putty or RDP.
Plaintext means I can grep years worth of reports to query what is effectively my cyborg memory. I use hyperref to create pdf hyperlinks, images are no problem. Provenance concerns are handled by my build script which commits everything to a git repository multiple times per day. If I want to scribble stuff without publishing it I just comment it out. The documents are available on the webserver for anyone to see.

UK Researcher Applies For Permission To Edit Embryo Genomes 62

sciencehabit writes with the news that developmental biologist Kathy Niakan, of the Francis Crick Institute in London, has applied for permission from the UK's Human Fertilization and Embryology Authority to edit the genes of human embryos. Niakan, says the article, "investigates the genes that are active at the earliest stages of human development, before it implants in the womb. Work with embryonic stem cells from mice and humans has suggested that some of the key genes active in this preimplantation period are different in humans and in mice. Niakan hopes to use genome editing to tweak some of the key genes thought to be involved and study the effects they have on human development." If approved, Niakan's work would only involve embryos in a lab, not implanted for gestation.

Some Trump Donors Get Fleeced By 3rd-Party Payment System 113

According to an article in Maine's WMTW Channel 8, some Donald Trump supporters claim they've ended up giving more than they intended to this campaign, because a since-resolved "glitch" (according to campaign spokeswoman Hope Hicks) meant they were charged multiple times. From the article: "Heather Nason of Saco told WMTW News 8 that her husband was one of the affected customers. ... Nason said a series of unauthorized charges appeared on her husband's bank statement days later. She said someone tried to make 13 withdrawals from her husband's account. After the first six charges went through, the account was almost empty."

Re-Examined IceCube Data Firms Up Case For Extra-Galactic Neutrinos 27

In 2013, the IceCube neutrino telescope detected dozens of high-energy neutrinos. Now, reports Astronomy magazine, researchers "have sorted through the billions of subatomic particles that zip through its frozen cubic-kilometer-sized detector each year to gather powerful new evidence in support of [those] 2013 observations confirming the existence of cosmic neutrinos." According to the report, Albrecht Karle from UW-Madison notes that while the neutrino-induced tracks recorded by the IceCube detector have a good pointing resolution, within less than a degree, the IceCube team has not observed a significant number of neutrinos emanating from any single source. ... “The plane of the galaxy is where the stars are. It is where cosmic rays are accelerated, so you would expect to see more sources there. But the highest-energy neutrinos we’ve observed come from random directions,” said Karle. “It is sound confirmation that the discovery of cosmic neutrinos from beyond our galaxy is real.”
