  • FAQ: What's so special about 802.11ad Wi-Fi?

    Here are the broad strokes about 802.11ad, the wireless technology that’s just starting to hit the market.

  • 2.5 and 5 Gigabit Ethernet Now Official Standards

    In 2014, multiple groups started efforts to create new mid-tier Ethernet speeds with the NBASE-T Alliance starting in October 2014 and MGBASE-T Alliance getting started a few months later in December 2014. While those groups started out on different paths, the final 802.3bz standard represents a unified protocol that is interoperable across multiple vendors.

    The promise of 2.5 and 5 Gbps Ethernet is that they can work over existing Cat5 cabling, which to date has only been able to support 1 Gbps. Now with the 802.3bz standard, organizations do not need to rip and replace cabling to get Ethernet that is up to five times faster.

    "Now, the 1000BASE-T uplink from the wireless to wired network is no longer sufficient, and users are searching for ways to tap into higher data rates without having to overhaul the 70 billion meters of Cat5e / Cat6 wiring already sold," David Chalupsky, board of directors of the Ethernet Alliance and Intel principal engineer, said in a statement. "IEEE 802.3bz is an elegant solution that not only addresses the demand for faster access to rapidly rising data volumes, but also capitalizes on previous infrastructure investments, thereby extending their life and maximizing value."

  • A quick fix for stupid password reset questions

    It didn’t take 500 million hacked Yahoo accounts to make me hate, hate, hate password reset questions (otherwise known as knowledge-based authentication or KBA). It didn't help when I heard that password reset questions and answers -- which are often identical, required, and reused on other websites -- were compromised in that massive hack, too.

    Is there any security person or respected security guidance that likes them? They are so last century. What is your mother’s maiden name? What is your favorite color? What was your first pet’s name?

  • French hosting provider hit by DDoS close to 1TBps

    A hosting provider in France has been hit by a distributed denial of service attack that went close to one terabyte per second.

    Concurrent attacks against OVH clocked in at 990GBps.

    The attack vector is said to be the same Internet-of-Things botnet of 152,464 devices that brought down the website of security expert Brian Krebs.

    OVH chief technology officer Octave Klaba tweeted that the network was capable of attacks up to 1.5TBps.

  • Latest IoT DDoS Attack Dwarfs Krebs Takedown At Nearly 1Tbps Driven By 150K Devices

    If you thought that the massive DDoS attack earlier this month on Brian Krebs’ security blog was record-breaking, take a look at what just happened to France-based hosting provider OVH. OVH was the victim of a wide-scale DDoS attack that was carried via network of over 152,000 IoT devices.

    According to OVH founder and CTO Octave Klaba, the DDoS attack reached nearly 1 Tbps at its peak. Of those IoT devices participating in the DDoS attack, they were primarily comprised of CCTV cameras and DVRs. Many of these types devices' network settings are improperly configured, which leaves them ripe for the picking for hackers that would love to use them to carry our destructive attacks. Servers Adoption

    As most of you know, E14N is no longer my main job, and I've been putting my personal time, energy, and money into keeping the pump network up and running. I haven't always done a good job, and some of the nodes have just fallen off the network. I'd like to ask people in the community to start taking over the maintenance and upkeep of these servers.

  • How to Resolve Your Open Content Management Quandary

    After years of development and competition, open source content management systems (CMS) have proliferated and are very powerful tools for building, deploying and managing web sites, blogs and more. You're probably familiar with some of the big names in this arena, including Drupal (which Ostatic is based on) and Joomla.

    As we noted in this post, selecting a CMS to build around can be a complicated process, since the publishing tools provided are hardly the only issue. The good news is that free, sophisticated guides for evaluating CMS systems have flourished. There are even good options for trying open CMS systems online before you choose one. Here, in this newly updated post, you'll find some very good resources.

    he first thing to pursue as you evaluate CMS systems to deploy, including the many free, good platforms, is an overview of what is available. is a great site for plotting out side-by-side comparisons of what CMS systems have to offer. In fact, it lets you compare the features in over 1200 content management system products. Definitely take a look. This site also has a good overview of the options.

  • Postleaf is an open-source blogging platform for the design-conscious

    Content management systems are boring until you have to use one. You can install a little Drupal or WordPress, pick up some Squarespace, or just dump to Medium, the graveyard for posts about protein shakes and VC funding. But what if you could roll your own CMS? And what if you made it really cool?

    That’s what Cory LaViska did. LaViska is the founder of SurrealCMS and has been making it easy to edit stuff on the web for nine years. Rather than build and sell an acceptable CMS, however, he took all of his best ideas and made a far better CMS. And he made it open source and called it Postleaf.

Death of Adobe Trash (Flash)

  • Chrome to make Flash mostly-dead in early December [Ed: but do we replace one blob with another? (Chrome is proprietary)]

    Google yesterday set an early December deadline for purging most Flash content from its Chrome browser, adding that it will take an interim step next month when it stops rendering Flash-based page analytics.

    In a post to a company blog, Anthony LaForge, a technical program manager on the Chrome team, said the browser would refuse to display virtually all Flash content starting with version 55, which is scheduled for release the week of Dec. 5.

    Previously, Google had used a broader deadline of this year's fourth quarter for quashing all Flash content except for that produced by a select list of 10 sites, including Amazon, Facebook and YouTube.

  • Google Chrome's plan to kill Flash kicks into high gear

    Google is getting serious about ending the reign of Adobe Flash on the web.

    The company recently detailed a timeline for bringing Flash on Chrome to an end—kind of. Even in these late stages of Flash’s life on the web you still can’t kill it off entirely. Instead, Google says it will “de-emphasize” Flash to the point where it’s almost never used except when absolutely necessary.

  • HTML5 Wins: Google Chrome Is Officially Killing Flash Next Month

    With an aim to bring security, better battery life, and faster load times, Google is de-emphasizing Flash next month. After this change in Chrome 53, the behind-the-scenes Flash will be blocked in favor of HTML5. Later, with Chrome 55, HTML5 will be made the default choice while loading a web page.

  • enables rapid deployment of UK government websites

    United Kingdom government websites can now be deployed within minutes by re-using the familiar theme produced by Government Digital Services (GDS) in combination with the Bootstrap framework.

    The open source software specialist OpusVL has made it possible to take the official Gov.UK website theme, which is under the MIT license, and reproduce it quickly and easily using Bootstrap, which originated from Twitter. Bootstrap is an HTML, CSS, and JavaScript framework for creating front end websites and applications. With an increase in the variety of devices used to view websites, Bootstrap is a standard tool kit for building responsive design, and enabling websites to be mobile- and tablet-friendly.

  • Acer updates Chromebook 15 with 12-hour battery life -- $199 exclusively at Walmart
    Chromebooks are not for everyone, but for many home users, it is absolute perfection. If you live in the web browser -- as many people do nowadays -- laptops running Google's Linux-based Chrome OS are a godsend because they are maintenance free. No need for confusing OS upgrades or anti-virus software. It just works, and it works well. Since they can now run Android apps too, they could become a serious threat to Microsoft and Windows 10. One of the most attractive aspects of Chromebooks is price -- they are often quite affordable. Today, Acer refreshes its 15.6 inch Chromebook 15 with a mind-boggling 12 hours of battery life. Best of all? It starts at $199. Yes, this model will get Android app support in a future update too.
  • Of Life, Linux and Karma Angels
    Angel filed appeal after appeal only to be denied on every attempt. Texas is an "at will" employment state so being terminated for cause can mean anything. Over the next few weeks, Angel became more and more fearful of losing her house, as she had just purchased it a year before. On top of that, her HP desktop had taken a nose dive into severe brokeness and that made it extra difficult for her to look for work. I put together a decent desktop for her and installed it that day, and was a Linux computer. Angel didn't have even the slightest problem with the new machine, and she wasn't particularly good at using one. So, let's put another slash in the falsehood that Linux is too hard for the everyday user. Most of them anyway. YMMV. To her glee, the OS picked up and configured her Epson all in one without her lifting a finger to do so. She almost clapped for happiness, stating that in Windows, installing that printer had been a nightmare, even with the included driver CD. And just to pinpoint the time frame for you, it was the summer of 2006.
  • Deus Ex: Mankind Divided to launch on Linux in November, Mac version delayed

The Linux version of the game will most likely make use of OpenGL or Vulkan to power its graphics engine.
  • Mad Max: It Came From The Desert to Linux
    First of all, let me get one thing straight out of the way, so you know where I come from. I did not like the recent Mad Max movie. Like, not at all. Not that I mind the post apocalyptic theme. I used to like the older Mad Max’s just fine (probably the first one the best). The new one…meh. The Max character had virtually no back story (as thin as a sheet of paper) and he was just acting like a crazy person from beginning to end. The story’s premise was boring and just an excuse for endless and not so impressive action scenes. So there was nothing redeeming it. I know this is not the mainstream opinion of the movie (everyone apparently thought it was the best thing ever since sliced bread) so I can only attribute this phenomenon to either mass hysteria or simply a clear decrease in movie expectations. The Force Awakens‘ success, despite being a mediocre movie and certainly underwhelming compared to the original trilogy, certainly echoes the same trend. I guess you cannot beat nostalgia. Just tag a Millennium Falcon on and you get a free ride no matter how incoherent the story or the characters are.

  • "dnf update" considered harmful
    Updating a Linux distribution has historically been done from the command line (using tools like Debian's apt-get, openSUSE's zypper, or Fedora's yum—or its successor dnf). A series of crashes during system updates on Fedora 24 led Adam Williamson to post a note to fedora-devel and other mailing lists warning people away from running "dnf update" within desktop environments. It turns out that doing so has never truly been supported—though it works the vast majority of the time. The discussion around Williamson's note, however, makes it clear that the command is commonly run that way and that at least some users are quite surprised (and unhappy) that it isn't a supported option.
  • Supporting UEFI secure boot in Debian
    The Debian project can be accused of many things, but jumping too quickly on leading-edge technology is not one of them. That can be seen in, among other things, the fact that there is still not a version of the distribution that supports the UEFI secure boot mechanism. But, as Ben Hutchings explained during his 2016 Kernel Recipes talk, such support is in the works, and it will be implemented in a uniquely Debian-like manner.
  • The Lenovo Yoga Book Is the Future of Laptops, But It's Missing an Operating System

They both feature Intel Atom x5-Z8550 processors, 4GB of RAM, 64GB of on-device storage, and 1920 x 1200 resolution displays. The Android version starts at $500 and the Windows version starts at $550.
  • Another Broken Nexus 5
    In late 2013 I bought a Nexus 5 for my wife [1]. It’s a good phone and I generally have no complaints about the way it works. In the middle of 2016 I had to make a warranty claim when the original Nexus 5 stopped working [2]. Google’s warranty support was ok, the call-back was good but unfortunately there was some confusion which delayed replacement. Once the confusion about the IMEI was resolved the warranty replacement method was to bill my credit card for a replacement phone and reverse the charge if/when they got the original phone back and found it to have a defect covered by warranty. This policy meant that I got a new phone sooner as they didn’t need to get the old phone first. This is a huge benefit for defects that don’t make the phone unusable as you will never be without a phone. Also if the user determines that the breakage was their fault they can just refrain from sending in the old phone.

  • UBIFS Working On File Encryption Support
    Following EXT4 file-system encryption and F2FS per-file encryption support, the UBIFS file-system is also bringing in encryption support built off this fscrypto framework used by EXT4/F2FS. In making use of fscrypto, the UBIFS file-system encryption support is similar to the EXT4/F2FS implementations and supports not only encrypting the file contents but also the file name. In making use of this framework, it only took around one thousand lines of new code to make it happen from the kernel-side while the user-space changes for supporting UBIFS encryption are still baking. UBIFS for those out of the look is the Unsorted Block Image File-System that's built atop UBI and designed for raw flash memory media.

    The original Prime Indicator hasn't been updated since February, 2015. André Brait forked the indicator (while also using code from the Linux Mint version), improving it with both new functionality and bug fixes, and the new app is called Prime Indicator Plus. Using the nvidia-prime package, Ubuntu users can switch between Intel and Nvidia graphics by using Nvidia Settings (under PRIME Profiles), which then requires restarting the session (logout/login) to apply the changes. Prime Indicator makes this easier, by allowing you to switch graphics from the indicator menu, including triggering the logout.

  • Blit, A Retrospective On My Largest Project Ever
    I’ve always been someone who’s liked art and programming. Especially combining the two. One of my favorite genres is pixel art, or sprites as they are also known. I’ve dabbled in making a few other art programs before, but nothing like this. Originally Blit supposed to be only a sprite animation tool that had a modern look and feel, but my ideas for it grew greater (*sigh* feature creep). There are many other sprinting tools out there like GrafX2, Aseprite, (and other 2D animation programs like TVPaint). I’m not saying that it’s wrong that they make their own GUI toolkit, but it feels kind of odd. I really wanted to bring these types of programs out of the days of the Amiga. After doing some initial research, I settled on using Qt.

While middleboxes provide in-network functionality that is necessary to keep networks manageable and economically viable, any packet mangling — whether essential for the needed functionality or accidental as an unwanted side effect — makes it more and more difficult to deploy new protocols or extensions of existing protocols. For the evolution of the protocol stack, it is important to know which network impairments exist and potentially need to be worked around. While classical network measurement tools are often focused on absolute performance values, PATHspider performs A/B testing between two different protocols or different protocol extensions to perform controlled experiments of protocol-dependent connectivity problems as well as differential treatment.
