An anonymous reader shares a report from Variety: Videos are coming to Reddit, thanks to a new feature that allows users to upload video clips directly to the service. Reddit rolled out the new video feature Tuesday after testing it with around 200 communities over the past couple of weeks. Reddit users are now able to upload videos of up to 15 minutes in length, with file sizes being limited to 1 gigabyte. Users will be able to upload videos via Reddit's website and its mobile apps for iOS and Android, with the latter offering basic trimming functionality as well. And, in keeping with the spirit of the site, Reddit is also offering a conversion tool to turn videos into animated Gifs. Videos are being displayed persistently, or pinned, meaning that users can scroll through the comments while the video keeps playing in the corner of their screen. And community moderators can opt not to allow videos in their Subreddits at all, with Le arguing that some discussion-heavy Subreddits may decide that the format just doesn't work for them.
After the PlayStation 4's 5.0 update was leaked last week, Sony decided to officially reveal what's coming in the update. GameSpot highlights the new features in their report: Some of the enhancements center around streaming using the PS4's built-in broadcasting capabilities. PS4 Pro users will be able to stream in 1080p and 60 FPS, provided their connection is strong enough, and PSVR users will be able to see new messages and comments coming through while broadcasting. PSVR is also adding 5.1ch and 7.1ch virtual surround sound support. Next up, the PS4's Friends List is being updated with greater management tools, such as the ability to set up separate lists of friends. You'll be able to create a list of all the people you play Destiny with and send them all an invite, for example. This feature replaces the old Favorite Groups tab. In another move to help reduce the amount of time spent in menus, the Quick Menu is being updated to have more options. For example, you'll be able to check on download progress and see new party invites. You can also leave a party from within that menu and see your current Spotify playlist. Notifications are also being improved when watching films and TV, as you can now disable message and other notification pop-ups while watching media. You can also change how much of a message is displayed, as well as its color, when playing or watching any form of content.
Finally, Parental Control features are being overhauled in favor of what Sony calls "Family on PSN." This replaces the old Master/Sub account system; instead, one user is deemed the Family Manager, and they can set up other accounts and appoint them as a Parent/Guardian, Adult, or Child. Parents or Guardians can restrict Child accounts in their "use of online features and communication with other players, set restrictions for games, restrict the use of the internet browser, and set spending limits for PlayStation Store." Note that Sony says the first time any North American user tries to set up an Adult account, they will be charged $0.50 "to verify that you are an adult."
schwit1 shares a report from The Hill: A hacker in Ukraine who goes by the online alias "Profexer" is cooperating with the FBI in its investigation of Russian interference in the U.S. presidential election, The New York Times is reporting. Profexer, whose real identity is unknown, wrote and sold malware on the dark web. The intelligence community publicly identified code he had written as a tool used in the hacking of the Democratic National Committee ahead of last year's presidential election. The hacker's activity on the web came to a halt shortly after the malware was identified. The New York Times, citing Ukrainian police, reported Wednesday that the individual turned himself into the FBI earlier this year and became a witness for the bureau in its investigation. FBI investigators are probing Russian interference efforts and whether there was coordination between associates of President Trump's campaign and Moscow. Special counsel Robert Mueller is heading the investigation.
An anonymous reader quotes a report from The Verge: A patent published today explains how a phone could identify cracks on its touchscreen and then apply heat to the area in an effort to slightly repair the damage. The process relies on something called "shape memory polymer," a material that can apparently become deformed and then recovered through thermal cycling. Thermal cycling involves changing the temperature of the material rapidly. This material could be used over an LCD or LED display with a capacitive touch sensor layered in, as well. Although the phone could heat the polymer in order to restore it, a user's body heat can be used, too.
In a blog post, Facebook announced that it has started downranking the News Feed presence of links that display a fake play button in the preview image, as well as videos that are actually just a static image uploaded as a video file. While Facebook won't completely delete these posts unless they violate its other policies, it will be decreasing the distribution of these stories. TechCrunch reports: Facebook has prohibited the use of fake play buttons in advertisements under its policy against depicting non-existent functionality for a few years, News Feed Product Manager Greg Marra tells me. But the scourage has remained in the News Feed. Facebook says that if publishers want to denote there's a video behind a link, they should indicate that through Open Graph meta tags. They could also use words like "Watch" or "Video" in the headline or description. Meanwhile, Facebook's emphasis on video in News Feed has inspired the new menace of publishers uploading a static image as a video to get more eyeballs. These static image videos will be downranked too. Facebook is using a "motion scoring" system that detects movement inside a video to classify and demote these clips.
According to iClarified, a hacker by name of "xerub" has posted the decryption key for Apple's Secure Enclave Processor (SEP) firmware. "The security coprocessor was introduced alongside the iPhone 5s and Touch ID," reports iClarified. "It performs secure services for the rest of the SOC and prevents the main processor from getting direct access to sensitive data. It runs its own operating system (SEPOS) which includes a kernel, drivers, services, and applications." From the report: The Secure Enclave is responsible for processing fingerprint data from the Touch ID sensor, determining if there is a match against registered fingerprints, and then enabling access or purchases on behalf of the user. Communication between the processor and the Touch ID sensor takes place over a serial peripheral interface bus. The processor forwards the data to the Secure Enclave but can't read it. It's encrypted and authenticated with a session key that is negotiated using the device's shared key that is provisioned for the Touch ID sensor and the Secure Enclave. The session key exchange uses AES key wrapping with both sides providing a random key that establishes the session key and uses AES-CCM transport encryption. Today, xerub announced the decryption key "is fully grown." You can use img4lib to decrypt the firmware and xerub's SEP firmware split tool to process. Decryption of the SEP Firmware will make it easier for hackers and security researchers to comb through the SEP for vulnerabilities.
An anonymous reader quotes a report from Ars Technica: AT&T has lost a court case in which it tried to stall construction by Google Fiber in Louisville, Kentucky. AT&T sued the local government in Louisville and Jefferson County in February 2016 to stop a One Touch Make Ready Ordinance designed to give Google Fiber and other new ISPs quicker access to utility poles. But yesterday, U.S. District Court Judge David Hale dismissed the lawsuit with prejudice, saying AT&T's claims that the ordinance is invalid are false. "We are currently reviewing the decision and our next steps," AT&T said when contacted by Ars today. One Touch Make Ready rules let ISPs make all of the necessary wire adjustments on utility poles themselves instead of having to wait for other providers like AT&T to send work crews to move their own wires. Without One Touch Make Ready rules, the pole attachment process can cause delays of months before new ISPs can install service to homes. Google Fiber has continued construction in Louisville despite the lawsuit and staff cuts that affected deployments in other cities.
From a new published paper in Scientific Report by Bjorn C. G. Karlsson and Ran Friedman: Despite the growing knowledge of the nature of water-alcohol mixtures on a molecular level, much less is known on the interaction of water, alcohol and small solutes. In particular, the nature of the interaction between the solvent and taste-carrying molecules, such as guaiacol, is not known. To address this gap, we used MD simulations to study the distribution of guaiacol in water-alcohol mixtures of different concentrations. Our simulations revealed that guaiacol is present at the air-liquid interface at ethanol concentrations that correspond to the alcohol content of bottled or diluted whiskies. Because the drink is consumed at the interface first, our findings help to understand why adding water to whisky helps to enhance its taste. A molecular understanding of the nature of taste compounds in water-alcohol mixtures allows for optimizing the taste of alcoholic spirits. [...] Overall, there is a fine balance between diluting the whisky to taste and diluting the whisky to waste.
An anonymous reader shares a report: For most of its 111-year history, Xerox has been known as one of the tech industry's most innovative companies. Now the legendary copier company is reinventing itself. In January, Xerox made the bold decision to split itself into two, spinning off its business services operations into a separate company called Conduent. And Jeffrey Jacobson, a Xerox tech executive, was tapped as Xerox's new CEO. Speaking with Fortune's Susie Gharib, Jacobson says Xerox is still "one of the top patent producing companies in the world" and he's counting on that scientific expertise to pivot the company to be a leader in digital print technology. "If I look at the things we're looking at with the Internet of things, artificial intelligence and bridging the digital and physical," he says, "that's what I think we'll be known for."
An anonymous reader shares a report: Leeds Beckett University has launched a chatbot to help prospective students find the right course. It follows the publication of A-level results in England, Wales and Northern Ireland. Using Facebook Messenger's chatbot technology, students would be able to "assess their suitability" for different courses, the university said. But if they would prefer to speak to a human, "phone lines will continue to be open throughout the clearing process." The university's head of digital experience and engagement, Dougal Scaife, said: "We know that our prospective students already use lots of messaging software for communicating with their friends, such as Snapchat, WhatsApp, as well as texting, so developing a chatbot was a natural evolution in order to engage with our prospective students in a medium that is ubiquitous, familiar, and comfortable for them."
Catalin Cimpanu, writing for BleepingComputer: A flaw buried deep in the hearts of all modern cars allows an attacker with local or even remote access to a vehicle to shut down various components, including safety systems such as airbags, brakes, parking sensors, and others. The vulnerability affects the CAN (Controller Area Network) protocol that's deployed in modern cars and used to manage communications between a vehicle's internal components. The flaw was discovered by a collaborative effort of Politecnico di Milano, Linklayer Labs, and Trend Micro's Forward-looking Threat Research (FTR) team. Researchers say this flaw is not a vulnerability in the classic meaning of the word. This is because the flaw is more of a CAN standard design choice that makes it unpatchable.
Merely weeks after it was announced that Bitcoin was splitting into two separate entities, the initial version of bitcoin and it's new "bitcoin cash," the network is adding a third version, according to a report. From the article: On Wednesday, a group of bitcoiners scheduled yet another split for the network in November, which would create a third version of bitcoin. So, what makes this version different from the others? Right now, the bitcoin network can sometimes take a long time to process transactions due to so many people using it. This is because the "blocks" of transaction data that get added to bitcoin's public ledger, the blockchain, are getting full. In the weeks preceding the fork, bitcoin coalesced around a solution called "segregated witness," which will change how data is stored in blocks to free up some space when it kicks in later in August. But the size of the blocks themselves will stay at one megabyte on the original bitcoin blockchain. Still, some bitcoiners maintained that the only way to speed bitcoin up for the foreseeable future was to increase the size of blocks themselves. So, a group of bitcoin companies and developers got together and launched a fork called bitcoin cash, which does not include segregated witness. It bumped the size of blocks up to a maximum of eight megabytes. That fork was widely anticipated to be a failure before it happened, but at the time of writing, bitcoin cash is trading above $300 USD per coin, which is comparable to cryptocurrencies like ethereum. Sounds like everyone got what they wanted, right? Oh, no. There's a third group of bitcoin developers, companies, and users who advocate for a "best of both worlds approach." This group includes Bitmain, the largest bitcoin infrastructure company in the world, and legendary bitcoin developer Jeff Garzik. They got together back in May and signed what is known as the "New York Agreement," which bound them to implement a two megabyte block size increase alongside segregated witness via a hard fork within six months of the time of signing. They call the fork Segwit2x. Now, that's exactly what's happening. According to an announcement posted to the Segwit2x GitHub repository, a bitcoin block between one and two megabytes will be created at block 494,784.
Electron, a popular framework that allows developers to write code once and seamlessly deploy it across multiple platforms, has been a topic of conversation lately among developers and users alike. Many have criticised Electron-powered apps to be "too memory intensive." A developer, who admittedly uses a high-end computer, shares his perspective: I can speak for myself when I say Electron runs like a dream. On a typical day, I'll have about three Atom windows open, a multi-team Slack up and running, as well as actively using and debugging my own Electron-based app Standard Notes. [...] So, how does it feel to run this bloat train of death every day? Well, it feels like nothing. I don't notice it. My laptop doesn't get hot. I don't hear the fan. I experience no lags in any application. [...] But aside from how it makes end-users feel, there is an arguably more important perspective to be had: how it makes software companies feel. For context, the project I work in is an open-source cross-platform notes app that's available on most platforms, including web, Mac, Windows, Linux, iOS, and Android. All the desktop applications are based off the main web codebase, and are bundled using Electron, while the iOS and Android app use their own native codebases respectively, one in Swift and the other in Kotlin. And as a new company without a lot of resources, this setup has just barely allowed us to enter the marketplace. Three codebases is two too many codebases to maintain. Every time we make a change, we have to make it in three different places, violating the most sacred tenet of computer science of keeping it DRY. As a one-person team deploying on all these platforms, even the most minor change will take at minimum three development days, one for each codebase. This includes debugging, fixing, testing, bundling, deploying, and distributing every single codebase. This is by no means an easy task.
From a report on The New York Times: Sheila James starts her Monday, and the workweek, at 2:15 a.m. This might be normal for a baker or a morning radio host, but Ms. James is a standard American office worker. She is 62 and makes $81,000 a year as a public health adviser for the United States Department of Health and Human Services in San Francisco. Her early start comes because San Francisco is one of the country's most expensive metropolitan areas. Ms. James lives about 80 miles away in Stockton, which has cheaper homes but requires her to commute on two trains and a bus, leaving at 4 a.m. Plenty of office workers get up at 5 a.m. or a bit before, but 2:15 is highly unusual. "Two-fifteen is early enough that some people are still having their evening," she said on a (very) early morning. But she likes to take her time and have coffee. She keeps the lights low and the house quiet and Zen-like. "I just can't rush like that," she said. When the second alarm goes off at 3:45 -- a reminder to leave for the train in 15 minutes -- her morning shifts from leisure to precision. It is a seven-minute drive to the station, where she catches the Altamont Corridor Express train.
An anonymous reader shares a report: New analysis of images thought to depict wreckage from missing Malaysian Airlines flight MH 370 suggest the Boeing 777 came down to the north of the area searched during efforts to find the plane. A new document [PDF] released yesterday by Geoscience Australia (GA) detailed analysis of four images captured by the PLEIADES 1A Earth-imaging satellite on March 23rd, 2014, not long after the March 8th disappearance of the plane. The images were provided to GA by the French Ministry of Defence. The images depict an area to the north and east of the area searched by underwater survey, and in-between areas where search and rescue operations were conducted in the wake of the plane's disappearance. The image displays the areas covered by underwater survey in yellow and the search and rescue zones in red. Extensive manual analysis of the images -- there was not enough data to use machine learning -- yielded a dozen objects that researchers were happy to classify as "probably not natural." Several of those objects were clustered in the northern parts of the areas depicted in the photos. The document is at pains to point out that it is not possible to identify the objects as airplane debris. The new analysis referred back to drift pattern analysis made on debris known to have come from MH370 and released in December 2016. That analysis suggested the search area be extended by 25,000km2. More detailed drift analysis released in April 2017 also called for a new search to the north, as did a July talk by scientists from Australia's Commonwealth Scientific and Industrial Research Organisation.

인생에서, 100% 순이익을 보장하는건 없다. 1%의 지식을 나눔으로써, 가끔씩 손해볼 필요도 있다.
그대가 가진 1%의 지식만이라도 공공을 위해 포스팅하라. 손해본다는 생각이 앞선다면 그대의 인생은 힘들어질것이다.
자신이 가진 지식의 1%도 투자하지 않고, 오로지 자신의 이익만 탐하는자와는 동지가 되지마라.
만나서 대화하면 모두 좋은 사람들이지만, 유독 인터넷에서만 자신을 밝히지 않고, 좀비로 서식하는 사람들이 많다.
부지불식간[不知不識間], 좀비(하류) 인생이 될지도 모르니, 항상 자신을 경계하도록 하라.
