Mapping the Whole IPv4 Internet with Hilbert Curves

Posted: 23 Apr 2018 08:14 AM PDT

Ben Cox writes in his blog about visualizing IPv4 address space use by mapping the whole IPv4 Internet with Hilbert curves. While the IPv4 address space is quite large it is still small enough to be able to send a packet to each and every IP address. He goes a little into the background of the maths involved and then makes a comparison to the IPv4 address space back in 2012 using data from the Carna botnet.

WikiLeaks Loses Access to a Key Cryptocurrency Account

Posted: 23 Apr 2018 06:40 AM PDT

This hasn't been the best week for WikiLeaks, to put it mildly. Coinbase has shut off the WikiLeaks Shop's account for allegedly violating the cryptocurrency exchange's terms of service. In other words, the leak site just lost its existing means of converting payments like bitcoin into conventional money. While Coinbase didn't give a specific reason (it declines to comment on specific accounts), it pointed to its legal requirement to honor "regulatory compliance mechanisms" under the US' Financial Crimes Enforcement Network.

This doesn't prevent WikiLeaks from accepting cryptocurrency, but it will have to scramble to find an alternative if it wants to continue taking digital money from customers buying shirts and coffee cups. Unsurprisingly, the organization is less than thrilled -- it's calling for a "global blockade" of Coinbase, claiming that the exchange is reacting to a "concealed influence."

Microsoft Ports Anti-Phishing Technology to Google Chrome Extension

Posted: 23 Apr 2018 05:03 AM PDT

Submitted via IRC for SoyCow8317

Microsoft has released a Chrome extension named "Windows Defender Browser Protection" that ports Windows Defender's —and inherently Edge's— anti-phishing technology to Google Chrome.

[...] Chrome users should be genuinely happy that they can now use both APIs for detecting phishing and malware-hosting URLs. The SmartScreen API isn't as known as Google's more famous Safe Browsing API, but works in the same way, and possibly even better.

An NSS Labs benchmark revealed that Edge (with its SmartScreen API) caught 99 percent of all phishing URLs thrown at it during a test last year, while Chrome only detected 87 percent of the malicious links users accessed.

Improved Stability of Plastic Light-Emitting Diodes

Posted: 23 Apr 2018 01:59 AM PDT

Monitor screens and smartphones that can be rolled and folded up are applications that could become possible in the future thanks to the development of polymer (plastic) based semiconductors.

Electronics from these conducting plastics pave the way for affordable, flexible and printable electronic components. A major obstacle hindering the market introduction of plastic based light-emitting diodes (PLEDs) is their relatively limited stability.

After a few months of continuous operation their light-output starts to decrease. In spite of many investigations in both industry and academic laboratories the cause of this degradation effect is only poorly understood.

Researchers at the Max Planck Institute for Polymer Research have recently discovered the mechanism causing the PLED degradation.

[...] The research results are published in the latest edition of the scientific journal Nature Materials. By using a mixture of two polymers (plastics) the effect of the defects can be strongly suppressed, leasing[sic] to improved stability of the PLEDs.

Zippo Keeps Your Bits Safe

Posted: 22 Apr 2018 11:28 PM PDT

Submitted via IRC for TheMightyBuzzard

[Laura Kampf] found a new use for an old Zippo lighter by turning it into a carrier for her screwdriver bits. There are several multitools out there which can accept standard screwdriver bits. The problem is carrying those bits around. Leaving a few bits in your pocket is a recipe for pocket holes and missing bits.

[Laura's] solution uses her old Zippo lighter. All she needs is the case, the lighter element itself can be saved for another project. A block of aluminum is cut and sanded down to a friction fit. Laura uses a band saw and bench sander for this. The aluminum block is then drilled out to fit four bits. Small neodymium magnets are taped into the holes with double-sided tape. These magnets retain the bits, ensuring none will fall out when the lighter is opened.

Does this mean we can start calling four bits a Zippo instead of a nibble now?

Food Allergy Linked to Skin Exposure and Genetics

Posted: 22 Apr 2018 09:17 PM PDT

Submitted via IRC for Bytram

Infant and childhood food allergy has now been linked to a mix of environmental and genetic factors that must coexist to trigger the allergy, reports a new study. Those factors include genetics that alter skin absorbency, use of infant cleansing wipes that leave soap on the skin, skin exposure to allergens in dust and skin exposure to food from those providing infant care. The good news is factors leading to food allergy can be modified in the home environment.

SmugMug Acquires Flickr

Posted: 22 Apr 2018 06:56 PM PDT

Submitted via IRC for fyngyrz

Two photo-sharing services are teaming up, as SmugMug buys Flickr from Verizon’s digital media subsidiary Oath. USA Today broke the news and interviewed SmugMug CEO Don MacAskill, who said he hopes to revitalize Flickr . At the same time, he said he's still figuring out his actual plans: "It sounds silly for the CEO to not to totally know what he's going to do, but we haven't built SmugMug on a master plan either. We try to listen to our customers and when enough of them ask for something that's important to them or to the community, we go and build it."

[...] In an FAQ about the deal, SmugMug says it will continue to operate Flickr as a separate site, with no merging of user accounts or photos: "Over time, we'll be migrating Flickr onto SmugMug's technology infrastructure, and your Flickr photos will move as a part of this migration — but the photos themselves will remain on Flickr."

New Electronic Book Format Unveiled: WebBook

Posted: 22 Apr 2018 04:39 PM PDT

Daniel Glazman believes that EPUB has reached a technical dead end.

  • It is impossible to aggregate a set of web pages into a EPUB book through a trivial zip, and it is impossible to unzip an EPUB book and make it readable inside a Web browser even with graceful degradation.
  • Despite the International Digital Publishing Forum merging with W3C in January 2017, EPUB continues to diverge from web standards.
  • The EPUB 3.1 specification has been rescinded because it is too costly and complex for the eBook industry to adopt.

Mr. Glazman's solution? The WebBook format. From the announcement:

I have then decided to work on a different format for electronic books, called WebBook. A format strictly based on Web technologies and when I say "Web technologies", I mean the most basic ones: html, CSS, JavaScript, SVG and friends; the class of specifications all Web authors use and master on a daily basis. Not all details are decided or even ironed, the proposal is still a work in progress at this point, but I know where I want to go to.

[...] I have started from a list of requirements, something that was never done that way in the EPUB world:

Robots Assemble IKEA Furniture - Humans Are Now Completely Superfluous

Posted: 22 Apr 2018 02:35 PM PDT

The hardest known human task has now been mastered by robots... assembling IKEA furniture (archive):

A team from Nanyang Technological University programmed a robot to create and execute a plan to piece together most of Ikea's $25 solid-pine Stefan chair on its own, calling on a medley of human skills to do so. The researchers explained their work in a study published on Wednesday in the journal Science Robotics.

"If you think about it, it requires perception, it requires you to plan a motion, it requires control between the robot and the environment, it requires transporting an object with two arms simultaneously," said Dr. Quang-Cuong Pham, an assistant professor of engineering at the university and one of the paper's authors. "Because this task requires so many interesting skills for robots, we felt that it could be a good project to push our capabilities to the limit."

He and his Nanyang colleagues who worked on the study, Francisco Suárez-Ruiz and Xian Zhou, aren't alone. In recent years, a handful of others have set out to teach robots to assemble Ikea furniture, a task that can mimic the manipulations robots can or may someday perform on factory floors and that involves a brand many know all too well. "It's something that almost everybody is familiar with and almost everybody hates doing," said Ross A. Knepper, an assistant professor of computer science at Cornell University, whose research focuses on human-robot interaction.

Loud Sound From Fire Alarm System Shuts Down Nasdaq's Scandinavian Data Center

Posted: 22 Apr 2018 11:50 AM PDT

Submitted via IRC for SoyCow8317

A loud sound emitted by a fire alarm system has destroyed the hard drives of a Swedish data center, downing Nasdaq operations across Northern Europe.

The incident took place in the early hours of Wednesday, April 19, and was caused by a gas-based fire alarm system that are typically deployed in data centers because of their ability to put out fires without destroying non-burnt equipment.

These systems work by releasing inert gas at high speeds, a mechanism usually accompanied by a loud whistle-like sound. With non-calibrated systems, this sound can get very loud, a big no-no in data centers, where loud sounds are known to affect performance, shut down, or even destroy hard drives.
