Reddit: My Ubuntu has a tendency to get the internet disabled?

Wednesday 28th of September 2016 09:26:03 AM

Everytime I use Ubuntu, after about half an hour, there tends to be a chance of the wifi/internet getting unavailable and I cannot connect to the internet.

What do you think is the problem? I was thinking to get a new installation version for this, but is this the way?

TuxMachines: Testing The BCache SSD Cache For HDDs On Linux 4.8

Wednesday 28th of September 2016 09:14:58 AM

It has been over one year since last testing the mainline Linux kernel's BCache support for this block cache that allows solid-state drives to act as a cache for slower hard disk drives. Here are some fresh benchmarks of a SATA 3.0 SSD+HDD with BCache from the Linux 4.8 Git kernel.

TuxMachines: Debian Project mourns the loss of Kristoffer H. Rose

Wednesday 28th of September 2016 08:59:25 AM

Kristoffer was a Debian contributor from the very early days of the project, and the upstream author of several packages that are still in the Debian archive nowadays, such as the LaTeX package Xy-pic and FlexML. On his return to the project after several years' absence, many of us had the pleasure of meeting Kristoffer during DebConf15 in Heidelberg.

  • Sloppy programming leads to OpenSSL woes
  • OpenSSL Fixes Critical Bug Introduced by Latest Update

    OpenSSL today released an emergency security update after a patch in its most recent update issued last week introduced a critical vulnerability in the cryptographic library.

  • The Internet Of Poorly Secured Things Is Fueling Unprecedented, Massive New DDoS Attacks

    Last week, an absolutely mammoth distributed denial of service (DDoS) attack brought down the website of security researcher Brian Krebs. His website, hosted by Akamai pro bono, was pulled offline after it was inundated with 620Gbps of malicious traffic, nearly double the size of the biggest attack Akamai (which tracks such things via their quarterly state of the internet report) has ever recorded. Krebs was ultimately able to get his website back online after Google stepped in to provide DDoS mitigation through its Project Shield service.

  • Trump Offers More Insight On His Cybersecurity Plans: 10-Year-Old Relatives Vs. 400-lb Bedroom Dwellers

    Look, anyone who refers to cybersecurity or cyberwarfare as "the cyber" is probably better off not discussing this. But Donald Trump, in last night's debate, felt compelled to further prove why he's in no position to be offering guidance on technological issues. And anyone who feels compelled to portray hackers as 400-lb bedroom dwellers probably shouldn't be opening their mouth in public at all.

    With this mindset, discussions about what "the Google" and "the Facebook" are doing about trimming back ISIS's social media presence can't be far behind. Trump did note that ISIS is "beating us at our game" when it comes to utilizing social media. Fair enough.

  • Docker Doubles Down on Microsoft Windows Server [Ed: recall "DockerCon 2015 Infiltrated by Microsoft"]

    Docker for Windows debuts alongside a new commercial support relationship with Microsoft.
    For the most part, the Docker container phenomenon has been about Linux, with the majority of all deployments on Linux servers. But that could soon be changing as Docker Inc. today is announcing the general availability of Docker Engine on Windows Server 2016, alongside a new commercial support and distribution agreement with Microsoft.

    Docker containers rely on the host operating system for certain isolation and process elements in order to run. On Linux, those elements have always been present as part of the operating system, but the same was not true for Windows, which has required several years of joint engineering effort between Docker Inc. and Microsoft.

  • Hadoop Sandboxes and Trials Spread Out

    We all know that there is a skills gap when it comes to Hadoop in the Big Data market. In fact, Gartner Inc.'s 2015 Hadoop Adoption Study, involving 284 Gartner Research Circle members, found that only 125 respondents who completed the whole survey had already invested in Hadoop or had plans to do so within the next two years. The study found that there are difficulties in implementing Hadoop, including hardship in finding skilled Hadoop professionals.

  • Use models to measure cloud performance

    When I was young, I made three plastic models. One was of a car—a '57 Chevy. Another was of a plane—a Spitfire. And a third was of the Darth Vader TIE Fighter. I was so proud of them. Each one was just like the real thing. The wheels turned on the car, and the plane’s propeller moved when you blew on it. And of course, the TIE Fighter had Darth Vader inside.

    When I went to work on the internet, I had to measure things. As I discussed in my last post, Measure cloud performance like a customer, when you measure on the internet you need to measure in ways that are representative of your customers’ experiences. This affects how you measure in two ways. The first is the perspective you take when measuring, which I talked about last time. The second way is the techniques you use to perform those measurements. And those techniques are, in effect, how you make a model of what you want to know. Those childhood plastic models turn out to offer some solid guidance after all.

  • ODPi Adds Apache Hive to Runtime Specification 2.0

    Today, ODPi announced that the ODPi Runtime Specification 2.0 will add Apache Hive and Hadoop Compatible File System support (HCFS). These components join YARN, MapReduce and HDFS from ODPi Runtime Specification 1.0

    With the addition of Apache Hive to the Runtime specification, I thought it would be a good time to share why we added Apache Hive and how we are strategically expanding the Runtime specification.

  • Ubuntu’s OpenStack on IBM’s Big Iron

    If I were Red Hat I would be looking over my shoulder right now; it appears that Ubuntu might be gaining. In just a few years the Linux distribution has gone from being non-existent in the enterprise to being a powerhouse. This is especially true in the cloud, where it's a dominant force on both sides of the aisle. Not only is it the most deployed operating system on public clouds, its version of OpenStack accounts for over half of OpenStack cloud deployments, used by the likes of Deutsche Telekom, Bloomberg and Time Warner Cable.

TuxMachines: Ubuntu 16.10 Final Beta Officially Released with Linux Kernel 4.8, Download Now

Wednesday 28th of September 2016 07:54:26 AM

Delayed six days, the Final Beta release of the upcoming Ubuntu 16.10 (Yakkety Yak) operating system launched today, September 28, 2016, as the final development snapshot in the series.

Today's Final Beta is in fact the first Beta pre-release version of Ubuntu 16.10, and the only development milestone that you'll be able to test if you want to see what's coming to the next major release of Ubuntu Linux. However, we can tell you that it is powered by Linux kernel 4.8, contains up-to-date applications, and still uses the Unity 7 UI.

"The Ubuntu team is pleased to announce the final beta release of Ubuntu 16.10 Desktop, Server, and Cloud products. Codenamed "Yakkety Yak", 16.10 continues Ubuntu's proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution.

TuxMachines: Parsix GNU/Linux 8.5 "Atticus" to Reach End of Life on September 30, 2016

Wednesday 28th of September 2016 07:47:02 AM

The Parsix GNU/Linux developers announced that the end-of-life status is approaching fast for the Parsix GNU/Linux 8.5 "Atticus" operating system, urging users to upgrade to the latest release immediately.

Dubbed Atticus and based on the Debian GNU/Linux 8.5 "Jessie" operating system, Parsix GNU/Linux 8.5 was unveiled seven months ago, on February 14, 2016. Running the long-term supported Linux 4.1.17 kernel injected with TuxOnIce 3.3 and BFS patches, it was built around the GNOME 3.18 desktop environment with the GNOME Shell 3.18.3 user interface.

The end of life (EOL) will be officially reached on September 30, 2016, which means that users of the Parsix GNU/Linux 8.5 "Atticus" operating system will no longer receive security and software updates. Therefore, they are urged today to upgrade to the latest, most recent version of the Debian-based distribution, Parsix GNU/Linux 8.10 "Erik."

TuxMachines: SteamOS 2.93 Brewmaster Beta Adds New Security Fixes from Debian GNU/Linux 8.6

Wednesday 28th of September 2016 07:41:29 AM

Valve's SteamOS 2 gaming operating system is still getting goodies, and it looks like a new Beta update has been pushed on September 26, 2016, to the brewmaster_beta channel for public beta testers.

That's right, SteamOS 2.93 Brewmaster Beta is here to replace the previous build announced earlier this month, SteamOS 2.91 Brewmaster Beta, and add the latest security fixes and updates from upstream. This means that SteamOS is now officially based on the recently released Debian GNU/Linux 8.6 "Jessie" operating system.

"SteamOS brewmaster update 2.93 pushed to brewmaster_beta. Corrects a build issue where the last kernel updates were not actually included. Also updates from the Debian 8.6 release[] and the usual security fixes," says John Vert, Valve engineer, in the release announcement.

  • 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 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.

One day later, the maintainers of other supported Linux kernel branches patched the bug, which is dubbed by researchers as "Dirty COW" and documented as CVE-2016-5195. As such, today we'd like to inform those of running GNU/Linux distributions powered by kernels from the Linux 3.16, 3.12, 3.10, and 3.2 series that new updates are available for their systems.

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.

Below are some features/functionality not currently found in Mesa 13.0. Some of the mentioned items have patches floating on the mailing list that weren't merged in time while other items are more along the lines of pipe-dreams that would have been fun to see in Mesa for 2016.

    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.

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.
