How to become a valued OpenStack contributor

Filed under

Most PTL’s are elected because they are the most technical contributor on a particular project. They are rarely elected for leadership skills. Most of our top technical contributors struggle with leadership, and naturally shy away from it. This frequently leads to dysfunction in community dynamics, as the PTL continues to focus on contributing at a very high level, and puts limited effort into leadership work. Doing things like setting project vision, tracking and celebrating milestones, providing team members with actionable feedback, and sharing the project vision with community members outside the project are all good ways of exhibiting leadership. Doing those things as a part time effort can yield limited results in terms of team unity, and effectiveness. My suggestion to open source project leaders is to earmark considerable time for leadership work, and scale back direct contribution work. A well empowered, motivated, and effective team can produce much more velocity than a PTL individually focused on strong contribution, and ignoring leadership responsibilities in order to do it.

Open source a clear choice for CMS development

Filed under

As time went on, we simply continued to ride the open source path. We assembled a huge collection of functional applications we had built for client sites that could be added to and modified for new ones. Shopping carts, contact forms, opt-in email list managers, employment opportunity listings, content editors, slide shows, all built as open source using PHP.

A few years later came the emergence of Content Management Systems, which contained—as a package—many of the functional elements we previously had relied upon our own resources to create. Drupal, Joomla!, Wordpress, and others were emerging as the default new development platforms for most digital agencies who had followed the same path as ours.

For Venom security flaw, the fix is in: Patch your VM today

Filed under

Venom, as described by its discoverer, Crowdstrike, an end-point security company, works by attacking QEMU's virtual Floppy Disk Controller (FDC). The first thing many of you think when learning this is: "Who cares, I've never used a floppy drive on my virtual machine (VM)!"

Ah, but, you don't have to activate the virtual floppy drive for a potential hacker snake to bite you. By default, the legacy floppy drive code is still in there, even though it's never been used. The corruption is still hiding in the code. So, even though you'd never dream of using a VM floppy drive, you're still open to attack.

3 big lessons I learned from running an open source company

Filed under

It all sounds so straightforward: Put your code up on GitHub or start/join a project at the Apache Software Foundation (ASF), build a community of like-minded individuals, start a company, take in some funding, and then IPO. Or maybe not. One thing is certain: Running an open source company has unique challenges and opportunities. Although much has been written on the subject of open source and community building, I'd like to share three critical lessons learned in my travels as a co-founder and CTO of a venture-backed open source company.

Comcast joined the OpenDaylight Project today and we wanted to share how we’ve been using the OpenDaylight platform and how it fits into our long-term network direction.

We have been testing ODL since the project launched to see where it might fit in and have been impressed by the improvements in functionality and stability with each successive release. We have also been participating with our partner CableLabs on the OpenDaylight sub-project PacketCable PCMM, which aims to develop a southbound plugin for ODL that can manage service flows across Cable Modem Termination System (CMTS) devices.

Leftovers: Software

  • i2pd 2.10 released
    i2pd (I2P Daemon) is a full-featured C++ implementation of I2P client. I2P (Invisible Internet Protocol) is a universal anonymous network layer. All communications over I2P are anonymous and end-to-end encrypted, participants don't reveal their real IP addresses. I2P client is a software used for building and using anonymous I2P networks. Such networks are commonly used for anonymous peer-to-peer applications (filesharing, cryptocurrencies) and anonymous client-server applications (websites, instant messengers, chat-servers). I2P allows people from all around the world to communicate and share information without restrictions.

  • 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.

  • FunYahoo++: New Yahoo Messenger Plugin For Pidgin / libpurple [PPA]
    Yahoo retired its old Messenger protocol in favor of a new one, breaking compatibility with third-party applications, such as Pidgin, Empathy, and so on. Eion Robb, the SkypeWeb and Hangouts developer, has created a replacement Yahoo prpl plugin, called FunYahoo++, that works with the new Yahoo Messenger protocol. Note that I tested the plugin with Pidgin, but it should work with other instant messaging applications that support libpurple, like BitlBee or Empathy.

  • GCC 7 To End Feature Development Next Month
    Friday's GCC 7 status report indicates the feature freeze is coming up in just a few weeks. Red Hat developer Jakub Jelinek wrote in the latest status report, "Trunk which will eventually become GCC 7 is still in Stage 1 but its end is near and we are planning to transition into Stage 3 starting Nov 13th end of day time zone of your choice. This means it is time to get things you want to have in GCC 7 finalized and reviewed. As usual there may be exceptions to late reviewed features but don't count on that. Likewise target specific features can sneak in during Stage 3 if maintainers ok them."

  • PATHspider 1.0.0 released!
    In today’s Internet we see an increasing deployment of middleboxes. 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.

Leftovers: KDE

  • Happy 20th birthday, KDE!
    KDE turned twenty recently, which seems significant in a world that seems to change so fast. Yet somehow we stay relevant, and excited to continue to build a better future. Lydia asked recently on the KDE-Community list what we were most proud of.

  • colord-kde 0.5.0 released!
    Last official stable release was done more than 3 years ago, it was based on Qt/KDE 4 tech, after that a few fixes got in what would be 0.4.0 but as I needed to change my priorities it was never released. Thanks to Lukáš Tinkl it was ported to KF5, on his port he increased the version number to 0.5.0, still without a proper release distros rely on a git checkout.
  • Call for attendees Lakademy 2017

  • Plasma 5 Desktop on FreeBSD Branding
    The FreeBSD packages of KDE software — the KDE 4 desktop, and soon KDE Frameworks 5 and Plasma 5 Desktop and KDE Applications — have traditionally been shipped pretty much as delivered from the upstream source. We compile, we package, and there is very little customization we do as a “distro”. The KDE 4 packages came with a default wallpaper that was a smidgen different from the one shipped with several Linux distro’s. I think Ivan Cukic did that artwork originally. For Plasma 5 Desktop, we also wanted to do a tiny bit of branding — just the default wallpaper for new users, mind.
  • A bit on Tooling
    So on the weekend I also worked on updating Qt 5.6.1 to Qt 5.6.2 on FreeBSD, which involves using new and scary tools as well. Power tools, they can be really useful, or they can take off a finger if you’re not careful. In this case it was Phabricator, which is also used in KDE — but not everywhere in KDE. For FreeBSD, the tool is used to review updates to ports (the packaging instructions), so I did an update of Qt from 5.6.1 to 5.6.2 and we handled the review through FreeBSD’s Phab. The ports infrastructure is stored in SVN, so the review is relatively straightforward: update the ports-tree checkout, apply your changes, use arc to create or update a review request. I was amazed by how painless it was — somehow I’d been frightened. Using the tool once, properly, makes a big difference in self-confidence.

    We’re still fixing bugs like madmen… And working on some cool new features as well, but that’s for a later release. In any case, here is the second Krita 3.1 beta! Yes, you’re reading that correctly. Originally, we had planned to use 3.0.2 as the version for this release, but there is so much news in it that it merits a bigger version bump.

  • GNOME Shell Making It Easy To Launch Apps/Games For Optimus / Dual GPU Systems
    With the GNOME 3.24 desktop that's currently in development the latest GNOME Shell code has support for easily letting the user launch an app on a dedicated GPU when applicable for handling NVIDIA Optimus use-cases of having integrated and discrete GPU laptops. When a dual-GPU system is detected, a menu item will be added to opt for "Launch using Dedicated Graphics Card", per this commit. The GNOME Shell change for supporting discrete GPUs was made and when the user opts to launch on the dedicated GPU, the DRI_PRIME=1 environment variable will automatically be set for that new program/game.
