  • Begin Broadcasting with a Powerful Open Source Media Platform

    But what a lot of people don't realize is that that it's definitely not just a media player. You can use it to stream and broadcast video, podcasts and other media content, and that includes streaming content to mobile devices of all kinds. Some organizations are integrating these streaming features with their networks and cloud deployments, embracing shared multimedia content. Here is our collection of guides for streaming with VLC, including guides for integrating it with your organization's publishing strategy. This newly updated collection has been expanded to include some very valuable new, free documentation.

  • AT&T (T) to Unveil ECOMP in Open Source Industry in 1Q17

    U.S. telecom giant AT&T Inc. T is moving ahead with plans to introduce its Enhanced Control, Orchestration, Management and Policy (ECOMP) virtualization platform in the open source industry in the first quarter of 2017. In relation to this, the company announced that it will release all 8.5 million lines of code for ECOMP. AT&T further claims that it has plans to standardize ECOMP as one of the best automated platforms for managing virtual network functions and other software-centric network operations in the telecom industry.

    Earlier in Sep 2016, AT&T and French telecom Orange S.A. ORAN had teamed up on open source initiatives in order to accelerate the standardization of software-defined networking (SDN) and network function virtualization (NFV). In relation to this, AT&T declared Orange as its first telecom partner to test its open-source Enhanced Control, Orchestration, Management, and Policy (ECOMP) platform.

  • How to Find Funding for an Open Source Project

    Ask people how to find funding for a technology project, and many of them will point to crowdsourcing sites. After all, the Oculus Rift virtual reality headset, the Pebble smartwatch, and even the low-cost Raspberry Pi computer were launched after their inventors collectively raised millions of dollars from contributors. If you happen to have an open source project that you want to get funded, what are some of your options?

  • vmm enabled

    With a small commit, OpenBSD now has a hypervisor and virtualization in-tree. This has been a lot of hard work by Mike Larkin, Reyk Flöter, and many others.

    VMM requires certain hardware features (Intel Nehalem or later, and virtualization enabled in the BIOS) in order to provide VM services, and currently only supports OpenBSD guests.

  • 50 tips for improving your software development game

    How do you keep improving as a software engineer? Some pieces of advice are valid no matter your experience level, but often the advice will depend on where you are in your career.

    If you're a beginner, the best advice is to simply learn your language, frameworks, and tools top to bottom and gain more experience with a variety of different projects.

    If you're an experienced software developer, you should constantly try to find new ways to optimize your code for readability, performance, and maintainability, and then practice making well-reasoned decisions about where to focus time and resources in your code—whether it's testing, performance optimization, or other technical debt.

  • 5900 online stores found skimming [analysis]

    Online card skimming is up 69% since Nov 2015


    In short: hackers gain access to a store’s source code using various unpatched software flaws. Once a store is under control of a perpetrator, a (Javascript) wiretap is installed that funnels live payment data to an off-shore collection server (mostly in Russia). This wiretap operates transparently for customers and the merchant. Skimmed credit cards are then sold on the dark web for the going rate of $30 per card .

  • GNU Guile 2.0.13 released [security fixes]

    We've just released a new version of GNU Guile, version 2.0.13, which is a security release for Guile (see the original announcement).

    This handles a significant security vulnerability affecting the live REPL, CVE-2016-8606. Due to the nature of this bug, Guile applications themselves in general aren't vulnerable, but Guile developers are. Arbitrary Scheme code may be used to attack your system in this scenario. (A more minor security issue is also addressed, CVE-2016-8605.)

    There is also a lesson here that applies beyond Guile: the presumption that "localhost" is only accessible by local users can't be guaranteed by modern operating system environments. If you are looking to provide local-execution-only, we recommend using Unix domain sockets or named pipes. Don't rely on localhost plus some port.

  • Free Software Directory meeting recap for October 7th, 2016
  • The Free Software Foundation seeks nominations for the 19th annual Free Software Awards

    This award is presented annually by FSF president Richard Stallman to an individual who has made a great contribution to the progress and development of free software, through activities that accord with the spirit of free software.

    Individuals who describe their projects as "open" instead of "free" are eligible nonetheless, provided the software is in fact free/libre.

    Last year, Werner Koch was recognized with the Award for the Advancement of Free Software for his work on GnuPG, the de facto tool for encrypted communication. Koch joined a prestigious list of previous winners including Sébastien Jodogne, Matthew Garrett, Dr. Fernando Perez, Yukihiro Matsumoto, Rob Savoye, John Gilmore, Wietse Venema, Harald Welte, Ted Ts'o, Andrew Tridgell, Theo de Raadt, Alan Cox, Larry Lessig, Guido van Rossum, Brian Paul, Miguel de Icaza, and Larry Wall.

Secure Desktops with Qubes: Compartmentalization

TuxMachines - Fri, 2016-10-14 01:48

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.

elementary OS 0.4: Review and interview with the founder

TuxMachines - Fri, 2016-10-14 01:44

Last month the elementary team released elementary OS “Loki” 0.4.

Needless to say, I wasted no time downloading and installing that bad boy on one of my machines. Even though I tend to use openSUSE on most of my desktops and laptops, I’ve had a soft spot for elementary since its very first release. It’s always been a high-quality, polished system—and the team behind it clearly care a great deal about the user experience.

3 command-line file conversion tools for Linux

TuxMachines - Fri, 2016-10-14 01:24

Recently, a friend innocently asked me how many file formats there are. My semi-serious response was, "Think of a soup bowl filled with beach sand."

OK, there aren't quite that many file formats. That said, you've probably never heard of many of the formats that are commonly used enough to warrant listing on Wikipedia. Chances are, you'll never see and never use most of them. If, however, you want or need to convert between file formats, then there are a quite a few applications for the job.

Let's take a look at three solid file conversion tools for the Linux command line.

Linux-based smart home hubs advance into AI

TuxMachines - Fri, 2016-10-14 01:14

Industrial, rather than home, applications will likely dominate the Internet of Things (IoT) market in the years to come. Yet, in the early going, the home automation market has had the greatest visibility. And it hasn’t always been pretty.

Despite steady growth, retail sales have yet to achieve inflated expectations. Too many companies promised and failed to deliver interoperability with a growing catalog of often buggy smart home products. The lack of essential applications, complex installation, and in many cases, high prices, have also conspired against the segment.

ddrescue and large drives advice

Reddit - Fri, 2016-10-14 01:11

I have an 8tb hard drive that started to fail with the following error.

kernel: sd 0:0:0:0: timing out command, waited 360s

From my searching it looked like this was an indicator that the drive is failing. Also, before I picked this error up from Splunk I did experience system hangs when accessing this drive with samba or pretty much anything that was reading/writing to it. Not a huge deal. I do have offsite incremental nightly backup, but this is really irritating me. Here we go....

I started with ddrescue (with log file) with the below command

# Rescue Logfile. Created by GNU ddrescue version 1.18.1 # Command line: ddrescue -v -d -f -r3 /dev/sdd /dev/sde /Logz/dd_rescure.log # Start time: 2016-10-13 07:00:53

The rescue ran for over 36+ hours and I did need to restart the machine and continue a few times because the disk was hung and block copy stopped.

(to note, for anyone reading this post make sure you check where the OS mounts your device each time you reboot! Each time it mounted at boot it did so with a different path. So if you start with /dev/sdd it could very well be /dev/sd[bcef] etc... on the next reboot. Of course on a working drive you would have the UUID in your FSTAB and you would probably never notice)

So I waited for 2 days chaperoning this drive copy and when It finally reached 100% I got the following error.

ddrescue no space left on device same size drive

Crap! Why! This was an 8TB to 8TB transfer, only difference was the manufacturer... going from Seagate to WD. So I continued digging, and this is what I found.

[joe@CERES ~]$ dmesg |grep sd[de] |grep blocks [ 2.810003] sd 0:0:0:0: [sdd] 15628053167 512-byte logical blocks: (8.00 TB/7.27 TiB) <--- Failing Seagate [ 2.810008] sd 0:0:0:0: [sdd] 4096-byte physical blocks [ 2.812180] sd 2:0:0:0: [sde] 15628052480 512-byte logical blocks: (8.00 TB/7.27 TiB) <--- New WD [ 2.812185] sd 2:0:0:0: [sde] 4096-byte physical blocks [joe@CERES ~]$

The new drive has 687 block (about 1/3 mb) LESS!

So the transfer fails and says it is out of space due to 1/3mb.... fabulous.

I know I only have 6.5TB of data on this drive, and likely those last few blocks (if written sequentially) are blank.

For monetary reasons I cant really afford a larger capacity drive (10 TB?)... and I don't want to go with another 8TB seagate.

This was an ext3 partition.

  • Is there a way that I can force finish the partition table and set this as the end point somehow?
  • can I somehow trim or offset these block from the failing drive?
  • Is there an option in ddrescue for situations like these. I did not find anything specific for this scenario in the documentation.
