Slashdot: Intel Launches Optane Memory That Makes Standard Hard Drives Perform Like SSDs

(posted on Tuesday April 25, 2017 at 18:00 AWST)

MojoKid writes: Intel has officially launched its Optane Memory line of Solid State Drives today, lifting embargo on performance benchmark results as well. Optane Memory is designed to accelerate the storage subsystem on compatible machines, to improve transfer speeds, and reduce latency. It is among the first products to leverage 3D XPoint memory technology that was co-developed by Intel and Micron, offering many of the same properties as NAND flash memory, but with higher endurance and certain performance characteristics that are similar to DRAM. The SSD can be paired to the boot drive in a system, regardless of the capacity or drive type, though Optane Memory will most commonly be linked to slower hard drives. Optane Memory is used as a high-speed repository, as usage patterns on the hard drive are monitored and the most frequently accessed bits of data are copied from the boot drive to the Optane SSD. Since the SSD is used as a cache, it is not presented to the end-user as a separate volume and works transparently in the background. Paired with an inexpensive SATA hard drive, general system performance is more in line with an NVMe SSD. In benchmark testing, Intel Optane Memory delivers a dramatic lift in overall system performance. Boot times, application load time, file searches, and overall system responsiveness are improved significantly. Setting up Intel Optane Memory is also quick and easy with "set it and forget it" type of solution. Optane Memory modules will hit retail this week in 16GB and 32GB capacities, at $44 and $77, respectively.

Slashdot: In Preparation For Model 3, Tesla Plans To Double the Size of Its Supercharger Network This Year

(posted on Tuesday April 25, 2017 at 15:00 AWST)

An anonymous reader quotes a report from Fortune: Tesla says it will double the number of electric vehicle chargers in its network this year as the automaker prepares for the production of its mass-market vehicle the Model 3. The plan, announced Monday in a blog post on the company's website, will grow its global network of Superchargers from more than 5,400 today to more than 10,000 by the end of the year. Tesla, which had previously announced in its annual shareholder letter plans to double the network in North America, did not disclose the cost of such an ambitious expansion. Many sites will soon enter construction to open in advance of the summer travel season, according to Tesla. The company says it will add charging locations within city centers as well as highway sites this year. The goal is to make "charging ubiquitous in urban centers," Tesla says in its blog post. The company says it will build larger sites along busy travel routes to accommodate several dozen Teslas simultaneously. These larger sites will also have customer service centers.

Slashdot: How Online Shopping Makes Suckers of Us All

(posted on Tuesday April 25, 2017 at 11:30 AWST)

Thelasko shares an excerpt from a report via The Atlantic, which describes how price discrimination is used in online shopping and how businesses like Amazon try to extract consumer surplus: Will you pay more for those shoes before 7 p.m.? Would the price tag be different if you lived in the suburbs? Standard prices and simple discounts are giving way to far more exotic strategies, designed to extract every last dollar from the consumer. We live in the age of the variable airfare, the surge-priced ride, the pay-what-you-want Radiohead album, and other novel price developments. But what was this? Some weird computer glitch? More like a deliberate glitch, it seems. "It's most likely a strategy to get more data and test the right price," Guru Hariharan explained, after I had sketched the pattern on a whiteboard. The right price -- the one that will extract the most profit from consumers' wallets -- has become the fixation of a large and growing number of quantitative types, many of them economists who have left academia for Silicon Valley. It's also the preoccupation of Boomerang Commerce, a five-year-old start-up founded by Hariharan, an Amazon alum. He says these sorts of price experiments have become a routine part of finding that right price -- and refinding it, because the right price can change by the day or even by the hour. (Amazon says its price changes are not attempts to gather data on customers' spending habits, but rather to give shoppers the lowest price out there.)

Slashdot: A Caterpillar May Lead To a 'Plastic Pollution' Solution

(posted on Tuesday April 25, 2017 at 09:45 AWST)

New submitter FatdogHaiku quotes a report from BBC: Researchers at Cambridge University have discovered that the larvae of the moth, which eats wax in bee hives, can also degrade plastic. Experiments show the insect can break down the chemical bonds of plastic in a similar way to digesting beeswax. The plastic is used to make shopping bags and food packaging, among other things, but it can take hundreds of years to decompose completely. However, caterpillars of the moth (Galleria mellonella) can make holes in a plastic bag in under an hour. They think microbes in the caterpillar -- as well as the insect itself -- might play a role in breaking down plastic. If the chemical process can be identified, it could lead to a solution to managing plastic waste in the environment.

Slashdot: Uber Gets Sued Over Alleged 'Hell' Program To Track Lyft Drivers

(posted on Tuesday April 25, 2017 at 09:05 AWST)

An anonymous reader quotes a report from TechCrunch: Uber has another lawsuit on its hands. This time, it's about Uber's alleged use of a program called "Hell." The plaintiff, Michael Gonzales, drove for Lyft during the time Uber allegedly used the software. He's seeking $5 million in a class action lawsuit. As the story goes, Uber allegedly tracked Lyft drivers using a secret software program internally referred to as "Hell." It allegedly let Uber see how many Lyft drivers were available to give rides, and what their prices were. Hell could allegedly also determine if people were driving for both Uber and Lyft. The lawsuit, filed in the U.S. District Court for the Northern District of California, alleges Uber broadly invaded the privacy of the Lyft drivers, specifically violated the California Invasion of Privacy Act and Federal Wiretap Act and engaged in unfair competition. Uber has not confirmed nor outright denied the claims.

Slashdot: Slashdot Asks: Which Wireless Carrier Do You Prefer?

(posted on Tuesday April 25, 2017 at 08:05 AWST)

Earlier this year, telecommunications giants like T-Mobile, AT&T, Verizon and Sprint were battling to see who could release the best unlimited data plan(s). T-Mobile started the domino chain reaction with the launch of its "One" unlimited plan in August. But the competition became especially fierce in February when Verizon introduced unlimited data plans of their own, causing Sprint and AT&T to unveil new unlimited data plans that same week, both of which have their own restrictions and pricing. Each of the four major carriers have since continued to tweak their plans to ultimately undercut their competitors and retain as many customers are possible. Given how almost everyone has a smartphone these days and the thirst for data has never been higher, we'd like to ask you about your current wireless carrier and plan. Which wireless carrier and plan do you have any why? Is there any one carrier or unlimited data plan that stands out from the others? T-Mobile, for example, recently announced that it added 1.1 million customers in Q1 2017, which means that it has added more than 1 million customers every quarter for the past four years. Have they managed to earn your business?

Slashdot: NSA's DoublePulsar Kernel Exploit a 'Bloodbath'

(posted on Tuesday April 25, 2017 at 07:20 AWST)

msm1267 quotes a report from Threatpost: A little more than two weeks after the latest ShadowBrokers leak of NSA hacking tools, experts are certain that the DoublePulsar post-exploitation Windows kernel attack will have similar staying power to the Conficker bug, and that pen-testers will be finding servers exposed to the flaws patched in MS17-010 for years to come. MS17-010 was released in March and it closes a number of holes in Windows SMB Server exploited by the NSA. Exploits such as EternalBlue, EternalChampion, EternalSynergy and EternalRomance that are part of the Fuzzbunch exploit platform all drop DoublePulsar onto compromised hosts. DoublePulsar is a sophisticated memory-based kernel payload that hooks onto x86 and 64-bit systems and allows an attacker to execute any raw shellcode payload they wish. "This is a full ring0 payload that gives you full control over the system and you can do what you want to it," said Sean Dillon, senior security analyst at RiskSense. Dillon was the first to reverse-engineer a DoublePulsar payload, and published his analysis last Friday. "This is going to be on networks for years to come. The last major vulnerability of this class was MS08-067, and it's still found in a lot of places," Dillon said. "I find it everywhere. This is the most critical Windows patch since that vulnerability." Dan Tentler, founder and CEO of Phobos Group, said internet-net wide scans he's running have found about 3.1 percent of vulnerable machines are already infected (between 62,000 and 65,000 so far), and that percentage is likely to go up as scans continue. "This is easily describable as a bloodbath," Tentler said.

Slashdot: Verizon's $70 Gigabit Internet Is Half the Price of Older 750Mbps Tier

(posted on Tuesday April 25, 2017 at 06:00 AWST)

An anonymous reader quotes a report from Ars Technica: Verizon is now selling what it calls "FiOS Gigabit Connection" for $69.99 a month in a change that boosts top broadband speeds and makes lower prices available to many Internet subscribers. Actual bandwidth will be a bit lower than a gigabit per second, with "downloads as fast as 940Mbps and uploads as fast as 880Mbps," Verizon's announcement today said. The gigabit service is available in most of Verizon's FiOS territory, specifically to "over 8 million homes in parts of the New York, New Jersey, Philadelphia, Richmond, Va., Hampton Roads, Va., Boston, Providence and Washington, D.C. areas," Verizon said. Just three months ago, Verizon boosted its top speeds from 500Mbps to 750Mbps. The standalone 750Mbps Internet service cost $150 a month, more than twice the price of the new gigabit tier. Existing customers who bought that 750Mbps plan "will automatically receive FiOS Gigabit Connection and will see their bills lowered," Verizon said. It's not clear whether they will get their price lowered all the way to $70. It's important to note that the $70 price is only available to new customers, and it's a promotional rate that will "increase after promo period." Additionally, Verizon will charge you a $10 per month router charge unless you pay $150 for the Verizon router, plus other taxes and fees.

Slashdot: Microsoft's Nadella Banks On LinkedIn Data To Challenge Salesforce

(posted on Tuesday April 25, 2017 at 05:20 AWST)

Microsoft is rolling out upgrades to its sales software that integrates data from LinkedIn, an initiative that Microsoft CEO Satya Nadella told Reuters was central to the company's long-term strategy for building specialized business software. From the report: The improvements to Dynamics 365, as Microsoft's sales software is called, are a challenge to market leader Salesforce.com and represent the first major product initiative to spring from Microsoft's $26 billion acquisition of LinkedIn, the business-focused social network. The new features will comb through a salesperson's email, calendar and LinkedIn relationships to help gauge how warm their relationship is with a potential customer. The system will recommend ways to save an at-risk deal, like calling in a co-worker who is connected to the potential customer on LinkedIn. [...] The artificial intelligence, or AI, capabilities of the software would be central, Nadella said. "I want to be able to democratize AI so that any customer using these products is able to, in fact, take their own data and load it into AI for themselves," he said. On Monday, LinkedIn said it has surpassed 500 million members globally, one of the first big milestones for the business social network since its acquisition.

Slashdot: Linux 4.11 Delayed For a Week

(posted on Tuesday April 25, 2017 at 04:40 AWST)

Linux kernel creator Linus Torvalds said over the weekend that v4.11 version of Linux has hit a speed bump in the form of "NVMe power management that apparently causes problems on some machines." The Register adds: "It's not entirely clear what caused the [NVMe] issue (it wasn't just limited to some NVMe hardware, but also particular platforms), but let's test it." Which sounds like a good idea, given that flash memory on the PCIe bus is increasingly mainstream. That problem and "a couple of really annoying" bugs mean that Torvalds has decided to do an eighth release candidate for Linux 4.11. "I did get fixes for the issues that popped up, so I could have released 4.11 as-is," Torvalds wrote, "but it just doesn't feel right."

Ubuntu Security Notices: Canonical joins EdgeX Foundry to help unify IoT edge computing

(posted on Monday April 24, 2017 at 22:09 AWST)

Fragmentation is the nature of the beast in the IoT space with a variety of non-interoperable protocols, devices and vendors which are the natural results of years of evolution in the industrial space especially. However traditional standardisation processes and proprietary implementations have been the norm. But the slow nature of their progress make them a liability for the burgeoning future of IoT. For these reasons, multiple actions are being taken by many organisations to change the legacy IoT mode of operations in the quest for accelerated innovation and improved efficiencies.

To aid this progress, today, the Linux Foundation has announced a new open source software project called the EdgeX Foundry. The aim is to create an open framework and unify the marketplace to build an ecosystem of companies offering plug and play components on IoT edge solutions. The Linux Foundation has gathered over 50 companies to be the founding members of this project and Canonical is proud to be one of these.
Here at Canonical, we have been pushing for open source approaches to IoT fragmentation. Last year’s introduction of snaps is one example of this – the creation of a universal Linux packaging format to make it easy for developers to manage the distribution of their applications across devices, distros and releases. They are also safer to run and faster to install. Looking forward, we want to see snaps as the default format across the board to work on any distribution or device from IoT to desktops and beyond.

Just like snaps, the EdgeX framework is designed to run on any operating system or hardware. It can quickly and easily deliver interoperability between connected devices, applications and services across a wide range of use cases. Fellow founding member, Dell, is seeding EdgeX Foundry with its FUSE source code base consisting of more than a dozen microservices and over 125,000 lines of code.

Adopting an open source edge software platform benefits the entire IoT ecosystem incorporating the system integrators, hardware manufacturers, independent software vendors and end customers themselves who are deploying IoT edge solutions. The project is also collaborating with other relevant open source projects and industry alliances to further ensure consistency and interoperability across IoT. These include the Cloud Foundry Foundation,EnOcean Alliance and ULE Alliance.

The EdgeX platform will be on display at the Hannover Messe in Germany from April 24th-28th 2017. Head to the Dell Technologies booth in Hall 8, Stand C24 to see the main demo.

Ubuntu Security Notices: ROS production: our prototype as a snap [3/5]

(posted on Friday April 21, 2017 at 17:40 AWST)

This is a guest post by Kyle Fazzari, Software Engineer. If you would like to contribute a guest post, please contact ubuntu-devices@canonical.com

This is the third blog post in this series about ROS production. In the previous post we came up with a simple ROS prototype. In this post we’ll package that prototype as a snap. For justifications behind why we’re doing this, please see the first post in the series.

We know from the previous post that our prototype consists of a single launch file that we wrote, contained within our prototype ROS package. Turning this into a snap is very straight-forward, so let’s get started! Remember that this is also a video series: feel free to watch the video version of this post.


This post will assume the following:

  • You’ve followed the previous posts in this series
  • You know what snaps are, and have taken the tour
  • You have a store account at http://myapps.developer.ubuntu.com
  • You have a recent Snapcraft installed (2.28 is the latest as of this writing)

Create the snap

The first step toward a new snap is to create the snapcraft.yaml. Put that in the root of the workspace we created in the previous post:

$ cd ~/workspace
$ snapcraft init
Created snap/snapcraft.yaml.
Edit the file to your liking or run `snapcraft` to get started

Do as it says, and make that file look something like this:

name: my-turtlebot-snap  # This needs to be a unique name
version: '0.1'
summary: Turtlebot ROS Demo
description: |

  Demo of Turtlebot randomly wandering around, avoiding obstacles and cliffs.

This is the basic metadata that all snaps require. These fields are fairly self-explanatory. The only thing I want to point out specifically here is that the name must be globally unique among all snaps. If you’re following this tutorial, you might consider appending your developer name to the end of this example.

grade: stable
confinement: devmode

grade can be either stable or devel. If it’s devel, the store will prevent you from releasing into one of the two stable channels (stable and candidate, specifically)– think of it as a safety net to prevent accidental releases. If it’s stable, you can release it anywhere.

confinement can be strict, devmode, or classic. strict enforces confinement, whereas devmode allows all accesses, even those that would be disallowed under strict confinement (and logs accesses that would otherwise be disallowed for your reference). classic is even less confined than devmode, in that it doesn’t even get private namespaces anymore (among other things). There is more extensive documentation on confinement available.

I personally always use strict confinement unless I know for sure that the thing I’m snapping won’t run successfully under confinement, in which case I’ll use devmode. I typically avoid classic unless I never intend for the app to run confined. In this case, I know from experience this snap won’t run confined as-is, and will require devmode for now (more on that later).

    plugin: catkin
    rosdistro: kinetic
    catkin-packages: [prototype]

You learned about this in the Snapcraft tour, but I’ll cover it again real quick. Snapcraft is responsible for taking many disparate parts and orchestrating them all into one cohesive snap. You tell it the parts that make up your snap, and it takes care of the rest. Here, we tell Snapcraft that we have a single part called prototype-workspace. We specify that it builds with Catkin, and also specify that we’re using Kinetic here (as opposed to Jade, or the default, Indigo). Finally, we specify the packages in this workspace that we want included in the snap. In our case, we only have one: that prototype package we created in the previous post.

    command: roslaunch prototype prototype.launch --screen
    plugs: [network, network-bind]
    daemon: simple

This is where things get a little interesting. When we build this snap, it will include a complete ROS system: roscpp, roslib, roscore, roslaunch, your ROS workspace, etc. It’s a standalone unit: you’re in total control of how the user interacts with it. You exercise that control via the apps keyword, where you expose specific commands to the user. Here, we specify that this snap has a single app, called system. The command that this app actually runs within the snap is the roslaunch invocation we got from the previous post. We use plugs to specify that it requires network access (read more about interfaces), and finally specify that it’s a simple daemon. That means this app will begin running as soon as the snap is installed, and also run upon boot. All this, and the user doesn’t even need to know that this snap uses ROS!

That’s actually all we need to make our prototype into a snap. Let’s create the snap itself:

$ cd ~/workspace
$ snapcraft

That will take a few minutes. You’ll see Snapcraft fetch rosdep, which is then used to determine the dependencies of the ROS packages in the workspace. This is only prototype in our case, which you’ll recall from the previous post depends upon kobuki_node and kobuki_random_walker. It then pulls those down and puts them into the snap along with roscore. Finally, it builds the requested packages in the workspace, and installs them into the snap as well. At the end, you’ll have your snap.

Test the snap

Even though we’re planning on using this snap on Ubuntu Core, snaps run on classic Ubuntu as well. This is an excellent way to ensure that our snap runs as expected before moving on to Ubuntu Core. Since we already have our machine setup to communicate with the Turtlebot, we can try it out right here. The only hitch is that /dev/kobuki isn’t covered by any interface on classic Ubuntu (we can make this work for Ubuntu Core, though, more on that later). That’s why we used devmode as the confinement type in our snap. We’ll install it with devmode here:

$ sudo snap install --devmode path/to/my.snap

Right after this completes (give it a second for our app to fire up), you should hear the robot sing and begin moving. Once you remove the snap it’ll stop moving:

$ sudo snap remove my-turtlebot-snap

How easy is that? If you put that in the store, anyone with a Turtlebot (no ROS required) could snap install it and it would immediately begin moving just like it did for you. In fact, why don’t we put it in the store right now?

Put the snap in the store

Step 1: Tell Snapcraft who you are

We’re about to use Snapcraft to register and upload a snap using the store account you created when satisfying the prerequisites. For that to happen, you need to sign in with Snapcraft:

$ snapcraft login

Step 2: Register the snap name

Snap names are globally unique, so only one developer can register and publish a snap with a given name. Before you can publish the snap, you need to make sure that snap name is registered to you (note that this corresponds to the name field in the snapcraft.yaml we created a few minutes ago):

$ snapcraft register <my snap name>

Assuming that name is available, you can proceed to upload it.

Step 3: Release the snap

In the tour you learned that there are four channels available by default. In order of increasing stability, these channels are edge, beta, candidate, and stable. This snap isn’t quite perfect yet since it still requires devmode, so let’s release it on the beta channel:

$ snapcraft push path/to/my.snap --release=beta

Once the upload and automated reviews finish successfully, anyone in the world can install your snap on the computer controlling their Turtlebot as simply as:

$ sudo snap install --beta --devmode my-turtlebot-snap

In the next post in this series, we’ll discuss how to obtain real confined access to the Turtlebot’s udev symlink on Ubuntu Core by creating a gadget snap, moving toward our goal of having a final image with this snap pre-installed and ready to ship.

Netcraft: April 2017 Web Server Survey

(posted on Friday April 21, 2017 at 16:45 AWST)

In the April 2017 survey we received responses from 1,816,416,499 sites and 6,320,910 web-facing computers. This reflects a gain of 56 million sites and 49,800 computers.

Microsoft had a noticeable gain of 108 million sites (+15.4%), recouping last month's loss and expanding its market share by nearly 5 percentage points to 44.7%. Microsoft is 10 million sites down from the start of the year, but its share is now nearly twice as large as Apache's. The only major vendor to suffer a loss of hostnames in April was nginx, which lost 1.4 million sites – this took its market share down by 0.41 points to 19.2%, leaving it slightly further behind Apache's share of 22.7%.

Despite nginx's loss of sites, it was once again the only major vendor to increase its presence within the top million sites, increasing its count by 2,164 sites, while Apache lost 1,962; but Apache stays in the lead with a 40.9% share, while nginx's increased to 28.7%.

nginx's growth is also reflected well in the web-facing computers market, where it had the largest increase of 29,900 computers (+2.44%). This took its share up by 0.32 points to 19.9%, while Apache's leading share fell by 0.27 points to 43.5%. Microsoft is still in second place with 24.2% of the web-facing computer market, but this position looks set to be taken by nginx within the next year if the trend of nginx's gains and Microsoft's losses continue.

Apache continues to reign supreme in terms of active sites, where it increased its market share slightly to 46.3%, putting it further ahead of nginx, which has a share of 19.6%; however, the long term trend over the past several years has seen the two vendors getting closer, with nginx slowly gaining market share while Apache has slowly declined. Microsoft's share of active sites is only 8.28%, but this is enough to keep it in third place, ahead of Google.

A new mainline version of nginx (1.11.13) was released on 4 April. This release included several bugfixes and formed the basis of the current stable version, nginx 1.12.0, which was later released on 12 April. As a consequence of including all bug fixes and new features from the entire 1.11.x branch, nginx 1.12.0 includes support for configuring multiple SSL certificates of different types, better support for dynamic modules, and several other new features.

Earlier this month, Netcraft examined the success of ICANN's New gTLD program, as well as the impact it has had on brand owners such as LEGO. The .loan gTLD saw the largest domain growth of any type of TLD this month, gaining 287,000 unique domains, yet losing more than 10 million websites. Only 3% of all .loan domains are considered active by Netcraft, indicating that large numbers share near-identical content, such as monetized domain holding pages.

From the TLD operator's perspective, the rise in .loan domains is much more significant than the large reduction in sites, as each unique domain will correspond to a domain registration, which invariably involves some type of transaction. The cost of registering a single .loan domain can vary between $20-$40 per year (including ICANN fees), depending which registrar is used, although some registrars – such as Namecheap – offer low introductory prices of $0.88 for the first year only. The prevalence of domain holding pages suggests that many of these domains may have been bought at introductory prices, so the estimated revenue from the 980,000 unique .loan domains currently in use on the web is likely to be much closer to $1m than $40m.
