  • [$] The kernel developer panel at LPC
    The closing event at the 2018 Linux Plumbers Conference (LPC) was apanel ofkernel developers. The participants were Laura Abbott, Anna-MariaGleixner, Shuah Khan, Julia Lawall, and Anna Schumaker; moderation wasprovided by Kate Stewart. This fast-moving discussion covered thechallenges of kernel development, hardware vulnerabilities, scaling thekernel, and more.


  • Security updates for Monday
    Security updates have been issued by Arch Linux (grafana and patch), Debian (chromium-browser), Fedora (cabextract, curl, elfutils, firefox, flatpak, glusterfs, kernel, kernel-headers, kernel-tools, kio-extras, libmspack, mariadb, mupdf, poppler, suricata, and wireshark), Mageia (hylafax+, jhead, libmspack/cabextract, nginx, sdl2/mingw-SDL2, and squid), openSUSE (amanda, apache-pdfbox, chromium, ImageMagick, LibreOffice and dependency libraries, libxkbcommon, openssh, systemd, and xorg-x11-server), and SUSE (ImageMagick, openssh, squid, and squid3).


  • Kernel prepatch 4.20-rc3
    The 4.20-rc3 kernel prepatch is out fortesting. "The changes in rc3 are pretty tiny, which means that thestatistics look slightly different from the usual ones - drivers onlyaccount for less than a third of the patch, for example."


  • Security updates for Friday
    Security updates have been issued by Fedora (lldpad, pdns, and php), Mageia (flash-player-plugin, gdal, mutt, patch, php-pear-CAS, postgresql9.4|6, ruby-rack, and teeworlds), SUSE (kernel-rt, postgresql10, and squid), and Ubuntu (openjdk-7).


  • [$] Bringing the Android kernel back to the mainline
    Android devices are based on the Linux kernel but, since the beginning,those devices have not run mainline kernels. The amount of out-of-treecode shipped on those devices has been seen as a problem for most of this time, and significant resources have been dedicated to reducing it.At the 2018 Linux PlumbersConference, Sandeep Patil talked about this problem and what is beingdone to address it. The dream of running mainline kernels on Androiddevices has not yet been achieved, but it may be closer than many people think.


  • Red Hat Enterprise Linux 8 Beta
    Red Hat has announcedthe release of RHEL 8 Beta. "Red Hat Enterprise Linux 8 Beta introduces the concept of Application Streams to deliver userspace packages more simply and with greater flexibility. Userspace components can now update more quickly than core operating system packages and without having to wait for the next major version of the operating system. Multiple versions of the same package, for example, an interpreted language or a database, can also be made available for installation via an application stream. This helps to deliver greater agility and user-customized versions of Red Hat Enterprise Linux without impacting the underlying stability of the platform or specific deployments."


  • Security updates for Thursday
    Security updates have been issued by Fedora (kde-connect, mingw-SDL2_image, SDL2_image, and subscription-manager), Red Hat (flash-plugin), SUSE (openssh-openssl1, systemd, and thunderbird), and Ubuntu (kernel, linux, linux-aws, linux-azure, linux-gcp, linux-kvm, linux-oem, linux-raspi2, linux, linux-aws, linux-gcp, linux-kvm, linux-raspi2, linux, linux-aws, linux-kvm, linux-raspi2, linux-snapdragon, linux-azure, linux-hwe, linux-azure, linux-gcp, linux-lts-trusty, linux-lts-xenial, linux-aws, postgresql-10, and python2.7).



  • [$] A report from the Automated Testing Summit
    In the first session of the Testing& Fuzzing microconference at the 2018 Linux Plumbers Conference (LPC), KevinHilman gave a report on the recently held Automated TestingSummit (ATS). Since the summit was an invitation-only gathering of 35people, there were many at LPC who were not at ATS but had a keeninterest in what was discussed. The summit came out of a realization thatthere is a lot of kernel testing going on in various places, but not a lotof collaboration between those efforts, Hilman said.


  • [$] Device-tree schemas
    Device trees have become ubiquitous in recent years as a way ofdescribing the hardware layout of non-discoverable systems, such as manyARM-based devices. The device-tree bindings define how a particularpiece of hardware is described in a device tree. Drivers then implementthose bindings. The device-tree documentation shows how to use the bindings to describe systems: which properties are available and which valuesthey may have. In theory, the bindings, drivers and documentation should beconsistent with each other. In practice, they are often not consistent and,even when they are, using those bindings correctly in actual device treesis not a trivial task. As a result, developers havebeen considering formal validation for device-tree files for years.Recently, Rob Herring proposeda move to a more structured documentation format for device-tree bindingsusing JSON Schema to allow automatedvalidation.

  • Acumos Project's 1st Software, Athena, Helps Ease AI Deployment
    The LF Deep Learning Foundation has announced the availability of the first software from the Acumos AI Project. Dubbed "Athena," it supports open source innovation in AI, ML and DL. The goal is to make critical new technologies available to developers and data scientists everywhere. Launched earlier this year, Acumos is part of a Linux Foundation umbrella organization.


  • Getting Clarity on the Private vs. Public Cloud Decision
    News flash: Private cloud economics can offer more cost efficiency than public cloud pricing structures. Private, or on-premises, cloud solutions can be more cost-effective than public cloud options, according to a report by 451 Research and Canonical. That conclusion counters the notion that public cloud platforms traditionally are more cost-efficient than private infrastructures.


  • Google Shows Off New Android Dev Tools
    Google has announced support for a range of new Android tools for application developers, chief among them the creation of a new support category for foldable devices. After years of speculation, it finally looks as though foldable screen smartphones are headed to market. Google's dev announcement followed closely on the heels of Samsung's announcement of a folding phone/tablet prototype.


  • IBM Dons Red Hat for Cloudy Future
    IBM's deal to acquire Red Hat caught everyone by surprise when it was announced less than two weeks ago. While concerns spread quickly about what it would mean for the largest enterprise Linux platform, IBM and Red Hat executives assured employees and customers that Red Hat would continue to operate independently -- at least for now. Intel made a similar acquisition of Wind River in 2009.


  • Got a Screwdriver? GalliumOS Can Turn Chromebooks Into Linux Boxes
    GalliumOS is a Chromebook-specific Linux variant. It lets you put a real Linux distro on a Chromebook. My recent review of a new Chromebook feature -- the ability to run Linux apps on some Chromebook models -- sparked my interest in other technologies that run complete Linux distros on some Chromebooks without using ChromeOS. GalliumOS can be a handy workaround.


  • Overcoming Your Terror of Arch Linux
    A recent episode of a Linux news podcast I keep up with featured an interview with a journalist who had written a piece for a non-Linux audience about giving it a try. It was surprisingly widely read. The writer's experience with some of the more popular desktop distributions had been overwhelmingly positive, and he said as much in his piece and during the subsequent podcast interview.


  • How to Protect Your Online Privacy: A Practical Guide
    Do you take your online privacy seriously? Most people don't. They have an ideal scenario of just how private their online activities should be, but they rarely do anything to actually achieve it. The problem is that bad actors know and rely on this fact, and that's why there's been a steady rise in identity theft cases from 2013 to 2017, often resulting in loss of reputation or financial woes.


  • Mobile Phone Security: All You Need to Know
    We rely on our phones to process and store reams of personal digital data. Our digital activities -- from checking bank balances to paying for a product with a tap of the screen, to sending friends and family messages over social media, to accessing work emails remotely -- have turned our phones into a goldmine of personal information. How secure is your mobile device?


  • Feren OS Delivers Richer Cinnamon Flavor
    Feren OS is a nice alternative to Linux Mint and an easy stepping stone to transition to Linux from Microsoft Windows or macOS. I am a long-time user of Linux Mint, but I am falling out of love with it. Mint is getting stale. That diagnosis started me thinking about a suitable replacement distro that runs the Cinnamon desktop with a bit more innovation and flare.


  • IT Resume Dos and Don'ts: Formatting for Readability
    I'd like to share some common of the most common formatting problems that I see regularly. Of course, an IT resume requires more than great formatting. It requires well-written, targeted content, and a clear story of career progression. It needs to communicate your unique brand and value proposition. Still, if the formatting is off, that can derail the rest of the document.

  • Norwegian Company Plans To Power Their Cruise Ships With Dead Fish
    An anonymous reader quotes a report from The Guardian: Waste fish parts will be used to power ships in a new initiative to use green energy for polluting cruise liners. The leftovers of fish processed for food and mixed with other organic waste will be used to generate biogas, which will then be liquefied and used in place of fossil fuels by the expedition cruise line Hurtigruten. Hurtigruten operates a fleet of 17 ships, and by 2021 aims to have converted at least six of its vessels to use biogas, liquefied natural gas -- a fossil fuel, but cleaner than many alternatives -- and large battery packs, capable of storing energy produced from renewable sources. Biogas can be generated from most forms of organic waste by speeding up and harnessing the natural decomposition process to capture the methane produced. Organic waste is produced by all food industries but is frequently disposed of in landfill, where it contributes to greenhouse gas emissions as it decomposes. Hurtigruten is currently building three new hybrid-powered cruise ships in Norway, to be delivered in the next three years.

  • Half-Life Celebrates 20th Anniversary With Fan-Made 'Black Mesa: Xen' Trailer
    On Monday, developer Crowbar Collective released the first trailer for Black Mesa: Xen, the final act of its long running remake of Valve's 1998 game Half-Life, which marked its 20-year anniversary on the same day. "The finale of Half-Life put hero Gordon Freeman in an alien world, and Black Mesa: Xen's upgraded graphics and redesign makes the original's muddy palette look vibrant and strange," reports Motherboard. "It looks just as exciting as it did at the time of the original game's release." From the report: When Valve unleashed Half-Life, it changed video games forever. The first person shooter from what was then a relatively unknown company starred a silent scientist beating down alien headcrabs and shooting human Marines in a novel sci-fi adventure. It was a triumph. Shortly after, in 2003, the Crowbar Collective began work on a remake that would come to be known as Black Mesa. Fan communities routinely reimagine their favorite video games, often as modifications, or mods, of the originals. Black Mesa began life as a free mod for Half-Life 2, but grew into a proper remake. Crowbar Collective added new voice work, changed animations, and tweaked the original game in hundreds of ways big and small. Black Mesa: Xen has a target release date of early 2019.

  • Ivanka Trump Used Personal Account For Emails About Government Business
    The Washington Post is reporting that Ivanka Trump used a personal email account to send hundreds of emails last year to White House aids, Cabinet officials and her assistants. Many of the emails were "in violation of federal records rules," the report says. Ivanka's practices are reminiscent of the personal email account Hillary Clinton used as secretary of state. From the report: White House ethics officials learned of Trump's repeated use of personal email when reviewing emails gathered last fall by five Cabinet agencies to respond to a public records lawsuit. That review revealed that throughout much of 2017, she often discussed or relayed official White House business using a private email account with a domain that she shares with her husband, Jared Kushner. Some aides were startled by the volume of Ivanka Trump's personal emails -- and taken aback by her response when questioned about the practice. Trump said she was not familiar with some details of the rules, according to people with knowledge of her reaction. A spokesperson for Ivanka Trump's attorney and ethics counsel, Abbe Lowell, "acknowledged that the president's daughter occasionally used her private email before she was briefed on the rules, but he said none of her messages contained classified information," reports Washington Post. "While transitioning into government, after she was given an official account but until the White House provided her the same guidance they had given others who started before she did, Ms. Trump sometimes used her personal account, almost always for logistics and scheduling concerning her family," he said in a statement. He went on to say that her email use was different than that of Clinton. "Ms. Trump did not create a private server in her house or office, no classified information was ever included, the account was never transferred at Trump Organization, and no emails were ever deleted," Mirijanian said.

  • In 'Digital India,' Government Hands Out Free Phones To Win Votes
    Forget the old American campaign slogan of a chicken in every pot, or the Indian politician's common pledge to put rice in every bowl. The New York Times reports: Here in the state of Chhattisgarh, the chief minister, Raman Singh, has promised a smartphone in every home -- and he is using the government-issued devices to reach voters as he campaigns in legislative elections that conclude on Tuesday. [...] The phones are the latest twist in digital campaigning by the B.J.P., which controls the national and state government and is deft at using tools like WhatsApp groups and Facebook posts to influence voters. The B.J.P. government in Rajasthan, which holds state elections next month, is also subsidizing phones and data plans for residents, and party leaders are considering extending the model to other states.   Chhattisgarh's $71 million free-phone program -- known by the acronym SKY after its name in Hindi -- is supposed to bridge the digital divide in this state of 26 million people, which is covered by large patches of forest and counts 7,000 villages that do not even have a wireless data signal. The plan is to add hundreds of cellphone towers and give a basic smartphone to every college student and one woman in every household to connect more families to the internet and help fulfill the central government's goal of a "Digital India." But this election season, many of the 2.9 million people who have received the phones have found themselves targeted by the B.J.P.

  • New Experimental Lockheed Supersonic Jet Starts Production
    Lockheed Martin's X-59 Quiet Supersonic Technology aircraft is officially in "the manufacturing phase," bringing the company "one step closer to enabling supersonic travel for passengers around the world." The experimental jet was awarded a contract from NASA earlier this year as it is capable of flying at supersonic speeds without creating loud supersonic booms. Currently, commercial supersonic aircraft are banned from flying over land because of the noise and potential damage the booms may cause. WTOP reports: "The long, slender design of the aircraft is the key to achieving a low sonic boom," said Peter Iosifidis, Low Boom Flight Demonstrator program manager at Lockheed Martin. "As we enter into the manufacturing phase, the aircraft structure begins to take shape, bringing us one step closer to enabling supersonic travel for passengers around the world," he said.   Lockheed expects to conduct its first flight in 2021 and gather community response data on the acceptability of the "quiet sonic boom" the plane creates. NASA will use that information to establish an acceptable commercial supersonic noise standard to overturn current regulations banning supersonic travel over land. The X-59 will cruise at a speed of about 940 mph and an altitude of 55,000 feet. Lockheed says it will create a sound about as loud as a car door closing, instead of a deafening sonic boom.

  • Russia Wants DNC Hack Lawsuit Thrown Out, Citing International Conventions
    An anonymous reader quotes a report from ZDNet: The Russian Federation has responded to a lawsuit filed by the Democratic National Committee and has requested the overseeing court to throw out the lawsuit altogether. The lawsuit, filed by the DNC in April 2018, names a slew of figures as defendants, such as the Russian state, Russia's military intelligence service GRU, the hacker known as Guccifer 2.0, WikiLeaks and its founder Julian Assange, and several members of the Trump campaign, such as Donald Trump, Jr., Paul Manafort, Roger Stone, Jared Kushner, and George Papadopoulos. According to an 87-page indictment, the DNC accused Russia and the other defendants of carrying out the hacking of DNC servers in 2016 and then leaking data online via the WikiLeaks portal in an orchestrated manner for the benefit of the Trump presidential campaign.   The lawsuit, which has its own Wikipedia page and was likened to a lawsuit the DNC filed against Nixon after the Watergate scandal, seeks damages, but also for the court to issue a declaration about the defendants' conspiracy. But in a letter sent to a New York court, presented by the Russian Embassy in the U.S. and signed by a representative of the Russian Ministry of Justice, the Russian Federation wants the lawsuit thrown out. In the 12-page letter, the Russian Federation argues that the U.S. Foreign Sovereign Immunities Act ("FSIA") grants Russia immunity. "The FSIA provides that foreign sovereign States enjoy absolute jurisdictional immunity from suit unless a plaintiff can demonstrate that one of the FSIA's enumerated 'exceptions' applies'," the letter argues. "The DNC's allegations regarding a purported 'military attack' by 'Russia's military intelligence agency' do not fall within any of the FSIA's enumerated exceptions to the Russian Federation's sovereign immunity." "Any alleged 'military attack' is a quintessential sovereign act that does not fall within any exception to the FSIA or the customary international law of foreign sovereign immunity. The Russian Federation's sovereign immunity with respect to claims based upon such allegations is absolute."

  • Yoshua Bengio, a Grand Master of Modern AI, is Worried About Its Future
    Yoshua Bengio is a grand master of modern artificial intelligence. Alongside Geoff Hinton and Yan LeCun, Bengio is famous for championing a technique known as deep learning that in recent years has gone from an academic curiosity to one of the most powerful technologies on the planet. Here's an excerpt from an interview he gave to MIT Technology Review: MIT TR: What do you make of the idea that there's an AI race between different countries?   Bengio: I don't like it. I don't think it's the right way to do it. We could collectively participate in a race, but as a scientist and somebody who wants to think about the common good, I think we're better off thinking about how to both build smarter machines and make sure AI is used for the well-being of as many people as possible.   MIT TR: Are you worried about just a few AI companies, in the West and perhaps China, dominating the field of AI?   Bengio: Yes, it's another reason why we need to have more democracy in AI research. It's that AI research by itself will tend to lead to concentrations of power, money, and researchers. The best students want to go to the best companies. They have much more money, they have much more data. And this is not healthy. Even in a democracy, it's dangerous to have too much power concentrated in a few hands.   MIT TR:There has been a lot of controversy over military uses of AI. Where do you stand on that?  Bengio: I stand very firmly against.  MIT TR: Even non-lethal uses of AI?   Bengio: Well, I don't want to prevent that. I think we need to make it immoral to have killer robots. We need to change the culture, and that includes changing laws and treaties. That can go a long way. Of course, you'll never completely prevent it, and people say, "Some rogue country will develop these things." My answer is that one, we want to make them feel guilty for doing it, and two, there's nothing to stop us from building defensive technology. There's a big difference between defensive weapons that will kill off drones, and offensive weapons that are targeting humans. Both can use AI.  MIT TR: Shouldn't AI experts work with the military to ensure this happens?   Bengio: If they had the right moral values, fine. But I don't completely trust military organizations, because they tend to put duty before morality. I wish it was different.

  • Google Patents Motorized, Omnidirectional VR Sneakers
    Google has patented motorized, omnidirectional virtual-reality sneakers that may solve the "limited space" problem associated with the interactive computer-generated experience. Ars Technica reports: Google's patent describes what are essentially motorized VR roller skates that will let the user walk normally while the motors and wheels work to negate your natural locomotion and keep you inside the VR safe zone. As the patent puts it, Google's new kicks will let you walk "seemingly endlessly in the virtual environment" while keeping you in one spot in real life. Google's shoe solution would track the user's feet, just like how VR controllers are tracked today. The tracking would know when you're too close to the virtual walls of your VR area, and the system would wheel you back into place.   Patents are always written to give the broadest possible coverage of an idea, but Google's patent shows normal wheels, tracks, and even omnidirectional mecanum wheels as possible wheels for the VR shoe bottoms. Omnidirectional wheels would be great, as they would allow you to do things like sidestep, while still having your position corrected by the shoes.

  • Bitcoin Falls Below $5,000 For First Time Since October 2017
    The value of Bitcoin has hit a new low of $4,951, bringing the total value of all Bitcoin in existence to below $87 billion. Much of the turmoil can be attributed to the split of Bitcoin Cash on November 15th. The Bitcoin offshoot has been split into two different cryptocurrencies, which are now in competition with each other. The BBC reports: Bitcoin exchange Kraken said in a blog post that it regarded one of the two new Bitcoin Cash crypto-currencies -- Bitcoin SV -- as "an extremely risky investment." At its peak, in November 2017, it briefly hit $19,783 - which means the price has fallen by about 75%. After the excitements of last year when the price soared to nearly $20,000 and then tumbled, Bitcoin has been rather dull and stable for much of 2018, settling between $6,000 and $7,000.

  • Southeast Asia's Digital Economy To Triple To $240 Billion By 2025, Says Google Report
    An anonymous reader quotes a report from TechCrunch: It may sit in the shade of China and India, but tech has real growth potential in Southeast Asia. Home to a cumulative 650 million people, the region's digital economy is forecast to triple in size and reach $240 billion over the next seven years, according to Google's third "e-Conomy SEA" report. The annual study, which is authored by Google and Singapore sovereign fund Temasek and is arguably the most comprehensive research program for tech in Southeast Asia, has raised its estimation for the size of the digital economy in 2025 from an initial $200 billion after seeing the region reach "an inflection point."   Southeast Asia has 350 million internet users across its six largest countries -- that's more than the entire U.S. population -- and the latest data suggests its internet economy will reach $72 billion this year, up from $50 billion last year and $19.1 billion in 2015. Online travel accounts for the majority of that revenue ($30 billion) ahead of e-commerce ($23 billion), online media ($11 billion) and ride-hailing ($8 billion), and that rough breakdown is likely to be maintained up until 2025, according to the report. Indonesia, the world's fourth largest country by population, is forecast to hit $100 billion by 2025, ahead of Thailand ($43 billion) and Vietnam ($33 billion), with strong growth forecast across the board. Indonesia and Vietnam, in particular, have seen their respective digital economies more than triple since 2015, according to the data.

    Given last week's new images release of the rolling-release, systemd-free, original-creation Void Linux I decided to take it for a spin with some fresh benchmarking as it had been two years or so since last trying out that Linux distribution with its XBPS packaging system. For seeing how the performance compares, I benchmarked it against some of the other primarily enthusiast/rolling-release/performant Linux distributions including Antergos, Clear Linux, Debian Buster Testing, Fedora Workstation 29, Manjaro 18.0, Sabayon Linux, Solus, and Ubuntu 18.10.

  • Pixel 3 bug disables the phone's camera

    Pixel 3 owners are dealing with another software glitch, and this one could prove to be a showstopper for some. Owners on Google's forums, Reddit and elsewhere (including an Engadget staff family member) report a flaw that prevents them from using the Pixel 3's official camera app. Some get a "fatal error" message when they use the camera app, while others will get a "can't connect to camera" message in a third-party app and lose access from then onward. Rebooting only temporarily fixes the issue, and it can occur even if you've factory-reset the phone or are using Safe Mode.

    It's not certain what's causing the problem. Charged inspected the camera code and believes it might stem from Android not properly releasing a lock on the camera, leading other apps to think it's still in use and prompting a crash.

    We've asked Google if it can comment on the reports. Support representatives haven't made it clear as to whether or not there will be a fix, though, and some owners said they were denied replacement units. Whatever the solution, it's a serious issue -- for all intents and purposes, this effectively renders the Pixel 3's signature feature useless. It could also frustrate early Pixel 3 buyers who've had to contend with multiple noticeable bugs virtually from the get-go.

  • Airbnb will remove guest home listings in the West Bank

    To date, Airbnb has argued that it would allow home listings in disputed areas in the name of connecting people. Now, it's changing its mind. The company plans to remove roughly 200 listings in Israeli settlements in the West Bank after rethinking its policies for contested regions. Airbnb didn't provide a detailed explanation of its rationale in this specific instance, but noted that the listings are "at the core of the dispute between Israelis and Palestinians."

    The firm said it was now considering issues like this on a "case-by-case" basis with help from both experts and its stakeholder community. The process would look for possible safety concerns, determine whether listings add to "existing human suffering" or have a "direct connection" to the dispute in question.

    While the company is positioning this as an ethical decision, there's a pragmatic incentive to withdraw the listings. Human Rights Watch is publishing a report on November 20th that will document Airbnb's "human rights harms" from allowing listings in the settlements. The company is clearly trying to get out in front of whatever comes tomorrow with the preemptive policy change.

  • Fan-made 'Half-Life' remake 'Black Mesa' is nearly complete

    Want to feel old? The released a trailer for the final portion of its Black Mesa remake, introducing its take on the strange Xen dimension that ends the first Half-Life game.

    The official take on Xen was distinctive for the time, although it threw players for a loop by shifting the focus from the human soldiers to decidedly strange aliens. It's not clear how the gameplay will change, but the Black Mesa interpretation certainly looks much better -- it's a mysterious, foreboding landscape. The finished Xen area should be available sometime in the second quarter of 2019.

    It's not shocking that enthusiasts would carry the torch. Valve has left the Half-Life franchise untouched for over a decade since HL2: Episode Two, and lost the franchise's last writer in 2017. It even joked about founder Gabe Newell's inability to understand the number three. While the company has lately renewed its interest in single-player content, Valve circa 2018 is primarily interested in its Steam game service and multiplayer titles like Rock Paper Shotgun, Eurogamer

  • You can now sync Chromecast with Google Home speakers

    Starting today, Google is allowing Chromecast owners to add the streaming device to speaker groups along with Home speakers. The addition of the dongle to the Home ecosystem will allow you to queue up a song, playlist, podcast or audiobook and have it play in sync across all of the speakers and Chromecast-connected devices in your home.

    XDA Developers spotted the functionality in Google's Preview program that gives an early look at upcoming features. Google confirmed to Engadget that the capability is starting to roll out to users today. The feature makes good on Google's promise to integrate Chromecast into speaker groups, which can be set up through the Google Home app. Now devices that connect with Chromecast, including televisions, can be added to a grouping. When a TV with Chromecast is synced to a speaker group, the display will show song information on screen, atop a rotating selection of background images.

    Per Home Hub and the LG Xboom WK9 will be able to be added to speaker groups in the coming weeks, according to pairbluetoothspeakers with the Home app to add voice control across your sound system.

  • The best early Black Friday 2018 deals

    This post was done in partnership with Wirecutter. When readers choose to buy Wirecutter's independently chosen editorial picks, Wirecutter and Engadget may earn affiliate commissions. that support its work. Read Wirecutter's continuously updated list of Black Friday deals here.
    Amazon Echo (2nd Generation) - Refurbished

    Street Price: $80; Deal Price: $60

    Only available in Heather Gray, this $60 refurbished sale on our pick in our Alexa guide is the best price we've seen on this model to date.

    The Amazon Echo (2nd Gen) is our pick of Amazon's Alexa-controlled speakers. Grant Clauser writes, "If you want music without hooking up any additional speakers, the second-generation Echo offers the complete range of functions, minus the screen features of the Show and Spot. As a speaker, it's good for kitchens, offices, dens, bedrooms, and other places where convenience and size (it's about the size of a Foster's beer can) is more important than audio performance. The speaker is designed for 360-degree dispersion, so placing it in the middle of the room will give you sound in all four corners."
    Audio-Technica LP60-BT Turntable
    Street Price: $150; Deal Price: $120

    Down to $120 in both Black and White, this pricing matches the low we've seen for this Bluetooth-enabled turntable. We haven't seen a deal on this turntable since the the summer.

    The Audio-Technica LP60-BT Turntable is the budget pick in our guide to the best turntable for casual listening. Chris Heinonen writes, "If you want something that can just play records easily for as little as possible, the Audio-Technica LP60-BT will do the job. Unlike the other tables we considered, LP60-BT is fully automatic: Press a button and the table spins while the arm moves into position. Once a record is done, the arm goes back into place and the table stops. It has a built-in phono stage and you can even get it with a Bluetooth output for use with wireless speakers."
    Yeti by Blue USB Microphone + Fallout 76 (PC) Bundle
    Street Price: $150; Deal Price: $100

    Back down to $140 from the typical street price of $180, this matches the low we've seen for this table-top streamer and includes the bonus of a free 3rd Gen (newest version) Echo Dot, around a $35 value.

    The Yeti by Blue USB Microphone is the top pick in our guide to the best USB microphone. Kevin Purdy and Lauren Dragan write, "It provided the most reliably well-rounded, natural sound out of all the mics we tested―whether on Windows or Mac, or whether recording happened in professional studios or in a small square office... It offers live headphone monitoring and gain control, two key features for any recording setup (other mics lacked these or made using them too complicated). It is more stable on its stand than most microphones we tested, and feels far more solidly constructed and durable."
    PlayStation Plus 1 Year Membership

    Street Price: $60; Deal Price: $40

    Matching Cyber Monday prices we saw last year, a 12 months subscription is back down to $40 from $60, still the best price we've seen.

    PlayStation Plus is mentioned alongside the PlayStation 4 in our guide for the best game consoles. Thorin Klosowski writes, "The PlayStation Plus subscription service provides online multiplayer and two free games a month, equivalent to what you get from the Xbox Live Gold service. Most people should get the standard PS4 model, not the PS4 Pro, unless you have a 4K TV or plan to buy one very soon."
    Samsung Galaxy S9

    Street Price: $700; Deal Price: $520

    A big drop from street price and a new low for all colors, this model comes unlocked with a US warranty.

    The Samsung Galaxy S9 is a runner-up pick in our guide to the best android phones. Ryan Whitwam writes, "The Samsung Galaxy S9 and its larger sibling, the Samsung Galaxy S9+, have some features that the Pixel 3 phones don't, such as a microSD card slot and a headphone jack. Plus, they're available for purchase through any carrier. These phones have the latest curved OLED screens from Samsung—the best we've ever seen on a phone—and the bezel surrounding the screen is tiny. The Galaxy S9's camera has an adjustable aperture, so it can take brighter low-light shots while also getting sharper photos in brighter light, though we still like the Pixel 3's camera more overall."
    DJI Tello Mini

    Street Price: $100; Deal Price: $80

    The first notable drop we've seen since we started tracking this already affordable drone.

    The DJI Tello Mini is an also great pick in our guide to the best drones under $100. Signe Brewster writes, "The DJI Tello, which is made in partnership with robotics company Ryze, is our pick if you're looking for an inexpensive drone that can take pictures and videos. It has surprisingly advanced autonomous features normally found on much more expensive drones. And its 5-megapixel, 720p camera—about the same resolution of an iPhone 4—takes good enough photos to make it fun for basic selfies and landscape pictures. It also has a 13-minute battery life, which is the longest of any drone we tested."

  • Twitter tweaks profiles in iOS app to emphasize names and bios

    If you've glanced at your Twitter profile lately and noticed your follower number has shrunk (in terms of text size, at least), you're probably not just seeing things. That's because Twitter has tweaked how profiles appear in its iOS app to place more focus on names and bios. A spokesperson told Engadget the company reduced the font size and spacing on details such as follower and followed account numbers, locations, join dates, birthdays and mutual follows.

    Twitter didn't explain why it made the subtle change, though its comms team noted last month that "we are rethinking everything about the service to ensure we are incentivizing healthy conversation," following reports it may remove the like button. The spokesperson noted Twitter was in the early stages of that work.

    CEO Jack Dorsey has spoken about how he'd like there to be less emphasis on metrics such as follower counts. He said last week that, rather than the number of likes and retweets you receive or how many people are following you, "what is more important is the number of meaningful conversations you're having on the platform" and whether people are replying to your tweets.

  • The Intel Core i9-9980XE review: refresh until it hertz
    AnandTech has published its comprehensive benchmarks and tests of the Intel Core i9-9980XE, and while this $2000 processor is unlikely to grace any of our computers, the article has some choice words for Intel. The problem with the 9980XE is that it's basically a 7980XE with slightly higher frequencies partly because Intel switched the TIM from paste to solder, and the numbers confirm this - the performance improvement isn't all that great.

    And this is a big problem for Intel.
    It all boils down to 'more of the same, but slightly better'  While Intel is having another crack at Skylake, its competition is trying to innovate, not only by trying new designs that may or may not work, but they are already showcasing the next generation several months in advance with both process node and microarchitectural changes. As much as Intel prides itself on its technological prowess, and has done well this decade, there's something stuck in the pipe. At a time when Intel needs evolution, it is stuck doing refresh iterations.
    Intel needs a breakthrough, because it can't keep sucking blood from the 14nm stone forever.


  • Impact assessment shows privacy risks of Microsoft Office
    The government of The Netherlands recently commissioned the Privacy Company to perform a data protection impact assessment regarding the government's use of Microsoft Office products, and the results of this assessment are alarming.
    The SLM Rijk conducts negotiations with Microsoft for approximately 300.000 digital work stations of the national government. The Enterprise version of the Office software is deployed by different governmental organisations, such as ministries, the judiciary, the police and the taxing authority.  The results of this Data Protection Impact Assessment (DPIA) are alarming. Microsoft collects and stores personal data about the behaviour of individual employees on a large scale, without any public documentation. The DPIA report (in English) as published by the Ministry is available here.
    This shouldn't surprise anyone, but it's good to see governments taking these matters seriously, and forcing technology companies to change their policies.


  • Limiting the power of package installation in Debian
    There is always at least a small risk when installing a package for a distribution. By its very nature, package installation is an invasive process; some packages require the ability to make radical changes to the system - changes that users surely would not want other packages to take advantage of. Packages that are made available by distributions are vetted for problems of this sort, though, of course, mistakes can be made. Third-party packages are an even bigger potential problem because they lack this vetting, as was discussed in early October on the debian-devel mailing list. Solutions in this area are not particularly easy, however.


  • Firefox Nightly now with experimental Wayland support
    As of last nightly (20181115100051), Firefox now supports Wayland on Linux, thanks to the work from Martin Stransky and Jan Horak, mostly.  Before that, it was possible to build your own Firefox with Wayland support (and Fedora does it), but now the downloads from mozilla.org come with Wayland support out of the box for the first time.
    The transition to Wayland seems to be taking its time, but with how big of an undertaking this is, that only makes sense.


  • International System of Units overhauled in historic vote
    Today, in a landmark decision, representatives from 60 countries voted to redefine the International System of Units (SI), changing the world's definition of the kilogram, the ampere, the kelvin and the mole, for ever.  The decision, made at the General Conference on Weights and Measures in Versailles, France, which is organised by the International Bureau of Weights and Measures (BIPM), means that all SI units will now be defined in terms of constants that describe the natural world. This will assure the future stability of the SI and open the opportunity for the use of new technologies, including quantum technologies, to implement the definitions.
    The metric system - or, as it is known today, the International System of Units (SI) - is an amazing achievement of mankind. Save for a few archaic holdouts who still measure things by sheep intestines and cow brains, the entire world has standardized on this system, so that regardless of where you are, things innately make sense.


  • How Facebook's leaders fought through crisis
    While Mr. Zuckerberg has conducted a public apology tour in the last year, Ms. Sandberg has overseen an aggressive lobbying campaign to combat Facebook's critics, shift public anger toward rival companies and ward off damaging regulation. Facebook employed a Republican opposition-research firm to discredit activist protesters, in part by linking them to the liberal financier George Soros. It also tapped its business relationships, lobbying a Jewish civil rights group to cast some criticism of the company as anti-Semitic.
    Revealing, but unsurprising recount of how Facebook went on the attack to ward off the numerous criticisms of the company. It doesn't susprise me one bit that Facebook isn't just a terrible company on the outside, but also on the inside.



  • Windows 10 to get white theme
    Microsoft released the latest Windows 10 insider build for next year's April Windows 10 update, and it contained a welcome susprise.
    Ever since we introduced the ability to choose between light and dark in Windows 10, we've heard feedback asking for a truer separation between the two options. When you select Light under Settings > Personalization > Colors, the expectation is that the system color would be lighter too. And it didn't do that before - the taskbar and many other things stayed dark. Now, if you choose Light under Settings > Personalization > Colors, all system UI will now be light. This includes the taskbar, Start menu, Action Center, touch keyboard, and more.
    This looks really, really nice. There's a few other changes in this build as well, but do note we're very early in the development process, so these builds are not for the faint of heart.


  • The vacuum tube's many modern day uses
    Among obscure pop culture tidbits and stories about wacky inventions, Tedium has often documented the continued survival of technology long thought of as obsolete. From calculagraphs to COBOL, we love hearing that ancient tech survives in the 21st century and revel in the uses that keep them around. So it was surprising to dig through the Tedium archives looking for something I expected to find, but didn't. Today, we're righting that wrong and diving into the robust and thriving world of a technology that was foundational to the progress humanity made during the 20th century. Today's Tedium is talking vacuum tubes.


  • KDevelop 5.3 released
    A little less than a year after the release of KDevelop 5.2 and a little more than 20 years after KDevelop's first official release, we are happy to announce the availability of KDevelop 5.3 today. Below is a summary of the significant changes.

  • Schedule One-Time Commands with the UNIX at Tool
        by Kyle Rankin   
    Cron is nice and all, but don't forget about its cousin at.

    When I first started using Linux, it was like being tossed into the deep end of the UNIX pool. You were expected to use the command line heavily along with all the standard utilities and services that came with your distribution. At lot has changed since then, and nowadays, you can use a standard Linux desktop without ever having to open a terminal or use old UNIX services. Even as a sysadmin, these days, you often are a few layers of abstraction above some of these core services.

    I say all of this to point out that for us old-timers, it's easy to take for granted that everyone around us innately knows about all the command-line tools we use. Yet, even though I've been using Linux for 20 years, I still learn about new (to me) command-line tools all the time. In this "Back to Basics" article series, I plan to cover some of the command-line tools that those new to Linux may never have used before. For those of you who are more advanced, I'll spread out this series, so you can expect future articles to be more technical. In this article, I describe how to use the at utility to schedule jobs to run at a later date.
     at vs. Cron
    at is one of those commands that isn't discussed very much. When people talk about scheduling commands, typically cron gets the most coverage. Cron allows you to schedule commands to be run on a periodic basis. With cron, you can run a command as frequently as every minute or as seldom as once a day, week, month or even year. You also can define more sophisticated rules, so commands run, for example, every five minutes, every weekday, every other hour and many other combinations. System administrators sometimes will use cron to schedule a local script to collect metrics every minute or to schedule backups.

    On the other hand, although the at command also allows you to schedule commands, it serves a completely different purpose from cron. While cron lets you schedule commands to run periodically, at lets you schedule commands that run only once at a particular time in the future. This means that at fills a different and usually more immediate need from cron.
     Using at
    At one point, the at command came standard on most Linux distributions, but these days, even on servers, you may find yourself having to install the at package explicitly. Once installed, the easiest way to use at is to type it on the command line followed by the time you want the command to run:
      $ at 18:00  
    The at command also can accept a number of different time formats. For instance, it understands AM and PM as well as words like "tomorrow", so you could replace the above command with the identical:

  • Weekend Reading: Qubes
        by Carlie Fairchild   
    Qubes OS is a security-focused operating system that, as tech editor Kyle Rankin puts it, "is fundamentally different from any other Linux desktop I've used". Join us this weekend in reading Kyle's multi-part series on all things Qubes.

    Secure Desktops with Qubes: Introduction

    In this first article, I provide an overview of what Qubes is, some of the approaches it takes that are completely different from what you might be used to on a Linux desktop and some of its particularly interesting security features. In future articles, I'll give more how-to guides on installing and configuring it and how to use some of its more-advanced features.

    Secure Desktops with Qubes: Installation
    This is the second in a multipart series on the Qubes operating system. In my first article, I gave an overall introduction to Qubes and how it differs from most other desktop Linux distributions, namely in the way it focuses on compartmentalizing applications within different VMs to limit what attackers have access to in the event they compromise a VM. This allows you to use one VM for regular Web browsing, another for banking and a different one for storing your GPG keys and password manager. In this article, I follow up with a basic guide on how to download and install Qubes, along with a general overview of the desktop and the various default VM types.

    Secure Desktops with Qubes: Compartmentalization
    This is the third article in my series about Qubes. In the first two articles, I gave an overview about what Qubes is and described how to install it. One of the defining security features of Qubes is how it lets you compartmentalize your different desktop activities into separate VMs. The idea behind security by compartmentalization is that if one of your VMs is compromised, the damage is limited to just that VM.

  • New Raspbian Update, Qt Creator 4.8 Beta2 Released, Firefox Monitor Now Available in More Than 26 Languages, Chrome OS Linux Soon Will Have Access to Downloads Folder and Canonical Extends Ubuntu 18.04 Long-Term Support

    News briefs for November 16, 2018.

    Simon Long has released a new Raspbian update. This update includes a "fully hardware-accelerated version of VLC", version 3 of the Thonny Python development environment, improved desktop configuration and more. You can download the update from here.

    Qt Creator 4.8 Beta2 is now available. In addition to many bug fixes, the LLVM for the Clang code model is updated to version 7.0 and binary packages are updated to the Qt 5.12 prerelease. You can get the open-source version here.

    Firefox Monitor, the free services that tells you whether your email has been part of a security breach, is now available in more than 26 languages: "Albanian, Traditional and Simplified Chinese, Czech, Dutch, English (Canadian), French, Frisian, German, Hungarian, Indonesian, Italian, Japanese, Malay, Portuguese (Brazil), Portuguese (Portugal), Russian, Slovak, Slovenian, Spanish (Argentina, Mexico, and Spain), Swedish, Turkish, Ukranian and Welsh." Along with this, Mozilla also announced that it has added "a notification to our Firefox Quantum browser that alerts desktop users when they visit a site that has had a recently reported data breach". See the Mozilla blog for details.

    Chrome OS Linux soon will be able to access your Downloads folder and Google Drive. According to the 9to5Google post, "Making the entire Downloads folder accessible will turn Linux apps into a first-class citizen on Chrome OS and will dramatically help with file organization and ease of use."

    Canonical and Ubuntu founder Mark Shuttleworth announced in his keynote at OpenStack Summit in Berlin that the Ubuntu 18.04 long-term support lifespan will be extended from five years to ten years. He also addressed IBM's acquisition of Red Hat. ZDNet reports that Shuttleworth indicated that this may lead customers to switch to Ubuntu, saying "We're neutral on the public cloud. We work at arm's length with AWS, Azure, and Google. We provide a common currency across different environment. But, we're not the lowest common denominator. We want to be the best operating system on Azure for Azure, AWS for AWS, and so on."

  • FOSS Project Spotlight: BlueK8s
        by Tom Phelan   
    Deploying and managing complex stateful applications on Kubernetes.

    Kubernetes (aka K8s) is now the de facto container orchestration framework. Like other popular open-source technologies, Kubernetes has amassed a considerable ecosystem of complementary tools to address everything from storage to security. And although it was first created for running stateless applications, more and more organizations are interested in using Kubernetes for stateful applications.

    However, while Kubernetes has advanced significantly in many areas during the past couple years, there still are considerable gaps when it comes to running complex stateful applications. It remains challenging to deploy and manage distributed stateful applications consisting of a multitude of co-operating services (such as for use cases with large-scale analytics and machine learning) with Kubernetes.

    I've been focused on this space for the past several years as a co-founder of BlueData. During that time, I've worked with many teams at Global 2000 enterprises in several industries to deploy distributed stateful services successfully, such as Hadoop, Spark, Kafka, Cassandra, TensorFlow and other analytics, data science, machine learning (ML) and deep learning (DL) tools in containerized environments.

    In that time, I've learned what it takes to deploy complex stateful applications like these with containers while ensuring enterprise-grade security, reliability and performance. Together with my colleagues at BlueData, we've broken new ground in using Docker containers for big data analytics, data science and ML/DL in highly distributed environments. We've developed new innovations to address requirements in areas like storage, security, networking, performance and lifecycle management.

    Now we want to bring those innovations to the Open Source community—to ensure that these stateful services are supported in the Kubernetes ecosystem. BlueData's engineering team has been busy working with Kubernetes, developing prototypes with Kubernetes in our labs and collaborating with multiple enterprise organizations to evaluate the opportunities (and challenges) in using Kubernetes for complex stateful applications.

    To that end, we recently introduced a new Kubernetes open-source initiative: BlueK8s. The BlueK8s initiative will be composed of several open-source projects that each will bring enterprise-level capabilities for stateful applications to Kubernetes.

You can order one here. The blog post notes that cases for the RPi 3 Model A+ will be available early next month.

    Red Hat Enterprise Linux 8 Beta makes its debut. RHEL 8 Beta features hundreds of improvements and several new features. One highlight is the introduction of "the concept of Application Streams to deliver userspace packages more simply and with greater flexibility". It also supports "more efficient Linux networking in containers through IPVLAN", has several security enhancements and more.

    The LF Deep Learning Foundation (a project of the Linux Foundation) yesterday announced the first software release of the Acumos AI Project, Athena. From the press release: "Acumos AI is a platform and open source framework that makes it easy to build, share and deploy AI applications. Acumos AI standardizes the infrastructure stack and components required to run an out-of-the-box general AI environment. This frees data scientists and model trainers to focus on their core competencies and accelerate innovation." See the full release notes here.

    Google's Project Fi has launched a new project allowing users to route all traffic through a Google-run VPN. According to The Verge, "your traffic will be going to Google's servers, so Google will be able to see what you're visiting." However, Google has said it isn't tying traffic to accounts or phone numbers or "any other user identifiers". The traffic also will be encrypted.

    Linux Deepin 15.8 was released today. The Deepin team notes that the "new release is featured with newly designed control center, dock tray and boot theme, as well as improved deepin native applications, hoping to bring users a more beautiful and efficient experience." To download, click here.

  • Getting Started with Scilab
        by Joey Bernard   
    Introducing one of the larger scientific lab packages for Linux.

    Scilab is meant to be an overall package for numerical science, along the lines of Maple, Matlab or Mathematica. Although a lot of built-in functionality exists for all sorts of scientific computations, Scilab also includes its own programming language, which allows you to use that functionality to its utmost. If you prefer, you instead can use this language to extend Scilab's functionality into completely new areas of research. Some of the functionality includes 2D and 3D visualization and optimization tools, as well as statistical functions. Also included in Scilab is Xcos, an editor for designing dynamical systems models.

    Several options exist for installing Scilab on your system. Most package management systems should have one or more packages available for Scilab, which also will install several support packages. Or, you simply can download and install a tarball that contains everything you need to be able to run Scilab on your system.

    Once it's installed, start the GUI version of Scilab with the scilab command. If you installed Scilab via tarball, this command will be located in the bin subdirectory where you unpacked the tarball.

    When it first starts, you should see a full workspace created for your project.

    Figure 1. When you first start Scilab, you'll see an empty workspace ready for you to start a new project.

    On the left-hand side is a file browser where you can see data files and Scilab scripts. The right-hand side has several panes. The top pane is a variable browser, where you can see what currently exists within the workspace. The middle pane contains a list of commands within that workspace, and the bottom pane has a news feed of Scilab-related news. The center of the workspace is the actual Scilab console where you can interact with the execution engine.

    Let's start with some basic mathematics—for example, division:
      --> 23/7  ans =   3.2857143  
    As you can see, the command prompt is -->, where you enter the next command to the execution engine. In the variable browser, you can see a new variable named ans that contains the results of the calculation.

    Along with basic arithmetic, there is also a number of built-in functions. One thing to be aware of is that these function names are case-sensitive. For example, the statement sqrt(9) gives the answer of 3, whereas the statement SQRT(9) returns an error.

    There also are built-in constants for numbers like e or pi. You can use them in statements, like this command to find the sine of pi/2:

  • Meet TASBot, a Linux-Powered Robot Playing Video Games for Charity
        by Allan Cecil   
    Can a Linux-powered robot play video games faster than you? Only if he takes a hint from piano rolls...and doesn't desync.

    Let me begin with a brief history of tool-assisted speedruns. It was 2003. Less than half the developed world had internet access of any kind, and YouTube hadn't been created yet. Smartphones were rare and nascent. Pentium III processors still were commonplace, and memory was measured in megabytes. It was out of this primordial ooze that an interesting video file circulated around the web—an 18MB .wmv labeled only as a "super mario bross3 time attack video" [sic]. What followed was an absolutely insane 11-minute completion of the game by someone named Morimoto replete with close calls, no deaths and Mario destroying Bowser after apparently effortlessly obtaining 99 lives. The only other context was a link to a page written in Japanese, and the rough encoding that Windows Media Video format was known for in that era made it difficult for casual viewers to observe that it was an emulator recording rather than the output of a real Nintendo Entertainment System (NES) console.

     Figure 1. Morimoto's 2003 Super Mario Bros. 3 (SMB3) Time Attack Video

    The video encode had in fact been made with the Famtasia NES emulator using Tool-Assisted Speedrun (TAS) re-recording tools consisting of a "movie file" of the sequence of all buttons pressed along with the use of savestates, or CPU and memory snapshots allowing returning to a previous state. Morimoto had in essence augmented his own human skill by using tools that allowed him to return to a previous save point any time he was dissatisfied with the quality of his play. By iteratively backing up and keeping only the best results, he had created what he considered at the time to be a perfect play-through of the game. I didn't know anything about how it was made the first time I saw the run, but it blew my mind and had me asking questions to which I couldn't find answers.

    The human speedrunning community members were naturally highly offended by what they saw as an unlabeled abomination akin to a doped athlete being allowed to compete in the Olympics. Their view was that anything that augmented raw human ability in any way (even as rudimentary as keyboard macros in PC games) was considered cheating, and Morimoto's run was nothing more than a fraud best left ignored. There was fascination, intrigue and division. It was, in retrospect, the perfect recipe for a new website.

  • Extended File Attributes Rock!
    Worldwide, data is growing at a tremendous rate. However, one recent study has pointed out that the size of files is not necessarily growing at the same rate; meaning the number of files is growing rapidly. How do we manage all of this data and files? While the answer to that question is complex, one place we can start is with Extended File Attributes. Continue reading


  • Checksumming Files to Find Bit-Rot
    In a previous article extended file attributes were presented. These are additional bits of metadata that are tied to the file and can be used in a variety of ways. One of these ways is to add checksums to the file so that corrupted data can be detected. Let's take a look at how we can do this including some simple Python examples. Continue reading
