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 + - New formula massively reduces prime number memory requirements.

grcumb writes: Peruvian mathematician Harald Helfgott made his mark on the history of mathematics by solving Goldbach's Weak Conjecture, which every odd number greater than 5 can be expressed as the sum of three prime numbers. Now, according to Scientific American, he's found a better solution to the Sieve of Erasthones:

In order to determine with this sieve all primes between 1 and 100, for example, one has to write down the list of numbers in numerical order and start crossing them out in a certain order: first, the multiples of 2 (except the 2); then, the multiples of 3, except the 3; and so on, starting by the next number that had not been crossed out. The numbers that survive this procedure will be the primes. The method can be formulated as an algorithm.

But now, Helfgott has found a method to drastically reduce the amount of RAM required to run the algorithm:

Helfgott was able to modify the sieve of Eratosthenes to work with less physical memory space. In mathematical terms: instead of needing a space N, now it is enough to have the cube root of N.

So what will be the impact of this? Will we see cheaper, lower-power encryption devices? Or maybe quicker cracking times in brute force attacks?

Submission + - Vim 8.0 released! (google.com)

MrKaos writes: The venerable and essential vim has had it's first major release in 10 years. Lots of new and interesting features including, vim script improvements, JSON support, messages exchange with background processes, a test framework and a bunch of Windows DirectX compatibility improvements.
A package manager has been added to handle the ever-growing plug-in library, start-up changes and support for a lot of old platforms has been dropped.

Many Vimprovements!

Submission + - "HP pre-programmed failure date of non-HP ink cartridges in its printers" (myce.com)

An anonymous reader writes: HP has programmed a failure date for non-HP / private label ink cartridges in its printers. Users around the world started to complain on the 13th of September this year that their printer rejected their non-HP cartridges. HP claimed that a firmware update was the culprit, but also printers who never received an update since they were unpacked rejected the cartridges starting at that particular date.

Submission + - Oldest-ever proteins extracted from 3.8-million-year-old ostrich shells (sciencemag.org)

sciencehabit writes: Scientists have smashed through another time barrier in their search for ancient proteins from fossilized teeth and bones, adding to growing excitement about the promise of using proteins to study extinct animals and humans that lived more than 1 million years ago. Until now, the oldest sequenced proteins are largely acknowledged to come from a 700,000-year-old horse in Canada’s Yukon territory, despite claims of extraction from much older dinosaurs. Now geneticists report that they have extracted proteins from 3.8-million-year-old ostrich egg shells in Laetoli, Tanzania, and from the 1.7-million-year-old tooth enamel of several extinct animals in Dmanisi, Georgia. The teeth, buried at the fossil site that houses the earliest hominin remains outside Africa, came from extinct horses, rhinos, and deer. One team has also extracted proteins from 3.8-million-year-old ostrich eggshells from the site of some of the world’s earliest human footprints.

Submission + - Is Apache OpenOffice finally on the way out? (apache.org)

JImbob0i0 writes: After almost another year without a release and another major CVE leaving users vulnerable for that year the Chairman of the Project Management Committee has started public discussions on what it will entail to retire the project, following the Apache Board showing concern at the poor showing.

It's been a long battle which would have been avoided if Oracle had not been so petty. Did this behaviour actually help get momentum in the community underway though? What ifs are always hard to properly answer.

Hopefully this long drawn out death rattle will finally come to a close and the wounds with LibreOffice can heal with the last few contributors to AOO joining the rest of the community.

Submission + - A Docker Fork: Talk of a Split Is Now on the Table (thenewstack.io)

joabj writes: Could a fork be in Docker's future? A number of container software vendors, loosely coalesced around Google's Kubernetes container orchestration engine, want to see the (open sourced) Docker code base standardized, so they can build more reliable third-party products (such as orchestration engines) around the virtualization technology. Docker says it is making advancements too quickly to be fully standardized, though, so Google, Red Hat and CoreOS, and other companies are mulling alternative ideas, such as forking the Docker code base.

Submission + - BBC [UK] gets go-ahead to detect iPlayer packets over encrypted Wi-Fi. (telegraph.co.uk)

product_bucket writes: The BBC has been given permission to use a new technology to detect users of the iPlayer who do not hold a TV licence. Researchers at University College London have apparently developed a method to identify specially crafted packets over an encrypted Wi-Fi link without needing to break the underlying encryption itself. TV Licensing (the fee-collecting arm of the BBC) has said the practice is under regular scrutiny by independent regulators, but declined to elaborate on how the technique works.

Submission + - Ask Slashdot: Living on the command line? (networkworld.com)

LichtSpektren writes: Last month, Bryan Lunduke of Network World began a public experiment where he tried to live 30 days without using X.org, i.e. using the command line exclusively. He ended up surrendering on day 10 because "attempting to use sites such as Google+, LinkedIn or Facebook—directly from terminal-based web browsers—is a truly painful experience. It can be made to work. Really. It can. But it’s just no fun at all." The series will probably come across as amusingly posh to people that spend most of their day in the terminal, but it is interesting note that Lunduke ends by saying that after the experiment, he now chooses to manage his music, notes, and instant messaging at the command line "because, I swear, it’s just such a nice experience."

I was just curious what things Slashdotters still do on the command line that's now commonplace to do with a GUI, such as watching YouTube videos. Skip the usual ones like vim/emacs, IRC, and just about anything a sysadmin does, since those are still widely done from the terminal and too obvious to mention. Is there anybody that uses Lynx for all web browsing, including this article? Are there any professional video/image/audio producers that do most of their work at the command line? Last year, Microsoft's April Fools' joke was MS-DOS for smartphones; is there anybody that seriously uses a terminal emulator to handle their text messages and calls?

Submission + - SPAM: MH370 Pilot Flew a Suicide Route on His Home Simulator Closely Matching Final Fl 1

schwit1 writes: Malaysia Airlines Flight 370 was likely steered into the sea intentionally, by its own captain, in a pre-planned mass murder-suicide, a new report reveals.

In an exclusive story posted online Friday, New York magazine says that the plane’s captain, Zaharie Ahmad Shah, “conducted a simulated flight deep into the remote southern Indian ocean less than a month before the plane vanished under uncannily similar circumstances.”

Submission + - SPAM: Physicists Combine Gold with Titanium And Quadruple Its Strength

schwit1 writes: When it comes to bone replacements, the go-to material is still titanium. Hard, wear-resistant, and compatible to the body, titanium looks like the best alternative to actual bone, maybe even better. Who knew that you could improve the ‘gold standard’ by just adding actual gold?

Rice University physicists have discovered that an alloy of titanium and gold is three to four times harder than steel, and may actually be better as a material for replacement body parts. The study, published in Science Advances , described the properties of an alloy of the two metals, a 3-to-1 mixture of titanium and gold, called Titanium-3. They found the alloy to be four times harder than titanium.

When they checked the biocompatibility and wear rate of the alloy, the researchers knew that it would rank high, since its parent metals are already biocompatible and used in medical implants. Surprisingly, Titanium-3 performed well over their expectations, actually being more biocompatible and wear resistant than pure titanium.

Gold-pressed latinum?

Submission + - Do Gut Bacteria Rule Our Minds? (ucsf.edu)

giorgioarmani writes: It sounds like science fiction, but it seems that bacteria within us – which greatly outnumber our own cells – may very well be affecting both our cravings and moods to get us to eat what they want, and often are driving us toward obesity.In an article published this week in the journal BioEssays, researchers from UC San Francisco, Arizona State University and University of New Mexico concluded from a review of the recent scientific literature that microbes influence human eating behavior and dietary choices to favor consumption of the particular nutrients they grow best on, rather than simply passively living off whatever nutrients we choose to send their way.

Submission + - ARM Holdings to be taken over by Japanese firm (bbc.co.uk)

Retron writes: One of the UK's leading tech companies, ARM Holdings, has been the subject of a hostile takeover bid from the Japanese firm Softbank. The bid values the shares at £17 each, a far higher price than the £11.88 they were worth at the close on Friday.

Chips using ARM technology are used in all sorts of gadgets and devices, from washing machines to iPads.

Submission + - Attacking Ransomware By Watching The Filesystem (phys.org)

An anonymous reader writes: Ransomware — what hackers use to encrypt your computer files and demand money in exchange for freeing those contents — is an exploding global problem with few solutions, but a team of University of Florida researchers says it has developed a way to stop it dead in its tracks.

The answer, they say, lies not in keeping it out of a computer but rather in confronting it once it's there and, counterintuitively, actually letting it lock up a few files before clamping down on it.

"Our system is more of an early-warning system. It doesn't prevent the ransomware from starting ... it prevents the ransomware from completing its task ... so you lose only a couple of pictures or a couple of documents rather than everything that's on your hard drive, and it relieves you of the burden of having to pay the ransom," said Nolen Scaife, a UF doctoral student and founding member of UF's Florida Institute for Cybersecurity Research.
Scaife is part of the team that has come up with the ransomware solution, which it calls CryptoDrop.

Submission + - Why Google Stores Billions of Lines of Code in a Single Repository (acm.org)

An anonymous reader writes: Google proves that distributed version control systems can't replace centralized ones. The centralized approach to source control has served Google well for more than 16 years, and today the vast majority of Google's software assets continues to be stored in a single, shared repository.

The Google codebase includes approximately one billion files and has a history of approximately 35 million commits spanning Google's entire 18-year existence. The repository contains 86TB of data, including approximately two billion lines of code in nine million unique source files.
