  • OSv: The Open Source Cloud Operating System That is Not Linux

    For most tech professionals, the words “open source operating system” naturally translate to Linux. And so it's understandable that those same tech pros would be a bit confused by startup Cloudius Systems' announcement in September of a new open source operating system for the cloud, OSv.

  • Inside the OpenMIND: Open Source Social Media Datamining and "Predictive" Policing

    Records obtained by DBA Press and the Center for Media and Democracy (DBA/CMD) shed new light on a technology, OpenMIND, utilized by law enforcement/counter-terrorism fusion center personnel in gathering and analyzing mass amounts of "open source intelligence" derived from the online lives of Americans.

  • SourceForge responds to GIMP grump with crowdsourcing caper
  • Andy Hunt: What are you going to invent next?

    Andy’s first point began with an astute observation. Open source software is often discussed in terms of being a "stack" (LAMP, for instance). It is no longer a stack, however, but a tower. A tower that spans software and hardware. With the source or schematics being available, not only can we stand on the shoulders of the giants of our field but on the shoulders of everyone who contributes. It’s an embarrassment of riches.

  • From simple bookkeeping packages to full-blown ERP systems, open source software can provide free options for small businesses that don't have the budget for big-ticket enterprise applications.

  • Then, now, and the future of open source fonts

    In August, the Fedora Project held its first Flock conference, a replacement for the North American and European FUDCon (Fedora Users and Developers Conference) events. Flock was a four-day, planned conference with talks, workshops, and hackfests, in contrast to FUDCon's barcamp model. In the interest of reaching beyond the community and reminding everyone that Fedora is so much broader than just a Linux project, the invited keynote speakers were from open source areas outside of the Fedora Project. One of those keynotes was by Dave Crossland, creator of the open font Cantarell and an active part of the free font movement.

  • Open Source: A Platform for Innovation

    The hobbies that inspired the scientific curiosity of my generation were Erector Sets, Science Fair Electronic Kits from Radio Shack and model rockets with balsa wood fins that we meticulously assembled and painted. While these toys piqued our curiosity in science and engineering our ability to share our discoveries were limited by geography. These fascinating distractions were often purpose-built and confined our creativity within their intended purpose.

  • A developer’s story about passion for Open Source and Security

    This story is definitely a first for me. Not just because every story is unique in itself, but that it’s one of personal matter. The thing is, I quit my well-paid job, just to spend time on the things I’m very passionate about: open source development and information security. Not only was quitting my job a serious step, also the decision to share my personal story after 10+ years of working with open source software and security. Well, here you go. It’s my hope to intrigue others, find their passion in life and also go for it!

  • Salsa: an open source syllabus creator for educators

    Who wants to tackle the complex problem of helping educators create learning service agreements? I don’t see too many hands. How about you there, reading this article? Wait, you weren’t aware that this is an issue that impacts the education system? Well, here's an open source project that solves this problem and needs more collaborators.

  • HHVM Going On A Big Performance, Feature Push

    Facebook's HipHop Virtual Machine (HHVM) open-source project that's been seeking to implement a high-performance PHP, is in the middle of a lock-down and for three weeks they are focusing on nothing bot boosting the performance of their PHP implementation and seeking to hit feature parity.

  • Matt Dugan Makes Case for Enterprise Open Source

    There was nothing new in what Matt Dugan said. There were no ground breaking revelations. He just methodically made his case, point by point, explaining why open source was usually, if not always, the best solution for business.

    To me, this was just what the doctor ordered. I’d just sat through a forty-five minute lecture in that very same room from an open core guy that had left me fearing that enterprise open source companies were just as greedy and potentially as unethical as the proprietary guys. Dugan fixed that and quickly reaffirmed my faith in the notion that open source is where the good guys live.

  • Machine Learning with Apache Mahout: Refining the Recommender

    Mahout components implement popular algorithms and can be unplugged easily when no longer needed.

  • MediaCore CE renamed to MediaDrop

    MediaCore CE is the community edition of MediaCore, a Web application that powers a multimedia hosted platform targeted towards the educational market and run by MediaCore, Inc. It is a Python application built atop the Django Web framework.

    Published under the GNU General Public License version 3, MediaDrop is free to download and use. However, because it is a Django application, installing it is a little bit more involved than the point-and-click process commonly associated with PHP applications.

  • OpenWFD Aims to Bring Wireless Display Streaming to Tablets, Phones

    Wireless connectivity between devices and display monitors remains mostly fantasy today, Google's Chromecast notwithstanding. But it could become a big deal for tablets, smartphones and even traditional PCs in the future. And it may even work on Linux, if the nascent OpenWFD project succeeds—which would be very good news for open source hardware vendors.

  • Open-Source HTML5 Terminal Emulator To Support X11

    The Gate One HTML5-powered terminal emulator and SSH client that goes without needing any browser plug-ins and supports many SSH/terminal features is working on bringing X11 support to the web-browser. The developer claims that this X11 support in the browser written in HTML5 will be fast enough to support video playback and he's made a video demo as proof.

Zapcc Liberated, HMM and GPL

  • Zapcc high-speed C++ compiler now open source
    Zapcc, a caching C++ compiler built for speed, has gone open source. Ceemple Software, Zapcc’s builder, claims the compiler offers dramatic improvements in both incremental and full builds compared to building with Clang 4.0 and Clang 5.0. Based on heavily modified code from the Clang compiler project, Zapcc uses an in-memory compilation cache in a client-server architecture. All compilation information is remembered between runs.
  • Heterogeneous memory management meets EXPORT_SYMBOL_GPL()
    One of the many longstanding — though unwritten — rules of kernel development is that infrastructure is not merged until at least one user for that infrastructure exists. That helps developers evaluate potential interfaces and be sure that the proposed addition is truly needed. A big exception to this rule was made when the heterogeneous memory management (HMM) code was merged, though. One of the reasons for the lack of users in this case turns out to be that many of the use cases are proprietary; that has led to some disagreements over the GPL-only status of an exported kernel symbol. The HMM subsystem exists to support peripherals that have direct access to system memory through their own memory-management units. It allows the ownership of ranges of memory to be passed back and forth and notifies peripherals of changes in memory mappings to keep everything working well together. HMM is not a small or simple subsystem, and bringing it into the kernel has forced a number of low-level memory-management changes. After a multi-year development process, the core HMM code was merged for the 4.14 kernel, despite the lack of any users.

Software: elementary OS Software, Unified Modeling Language (UML), PulseAudio 12.0 and Zstd

  • An Awesome List of Apps & Resources for elementary OS
    It is barely up to a day since I put up a positive review of elementary OS which is well deserved because it has come a long way from what it was 2 years ago when FossMint checked it out. The good news I’ve got for you today is that the developers have published a page on GitHub that contains “curated list of awesome applications, tools and shiny things for elementary OS”. They are grouped into categories for easy selection, are all open source, and clicking on the green tick icons will direct you to the app on elementary OS’s AppCenter.
  • Best Free Unified Modeling Language Tools
    Unified Modeling Language (UML) is a general-purpose, modeling language designed to provide a standard way for visualizing, specifying, constructing, and documenting the artifacts of distributed object systems. It’s the industry standard modeling language for software engineering. The aim of UML is to give software engineers, agile and small development teams, and system architects useful tools for analysis, design, and implementation of software-based systems. It also provides modeling business and similar processes. The language helps to visualize your object-oriented design and communicate with others. It offers limited use for other programming paradigms.
  • PulseAudio 12.0 release notes
    When playing videos, it's important that the audio latency is known so that the video can be synchronized accurately. PulseAudio doesn't get good latency information from the kernel with A2DP playback, which has caused A/V sync problems for many people when watching videos. Now PulseAudio makes the audio buffer in the kernel much smaller, which reduces the problem a lot.
  • PulseAudio 12.0 Released With Many Improvements
    PulseAudio 12.0 was quietly released yesterday as the newest version of this open-source, cross-platform sound server.
  • Zstandard – A Super Faster Data Compression Tool For Linux
    This is known topic and we were using in our day to day activity to compress and decompress files & folders. You might already know zip,tar,7-zip, etc and you would have used all these application for your requirement. Even today also we are going to discuss about similar kind of topic, the tool name is Zstandard. It is super fast data compression tool and compression ratio is very very low. Zstd is lossless data compression algorithm developed by Yann Collet at Facebook. Due to high data compression ratio many of the popular companies and databases are using this tool.

KDE: CMake 3.12 With FreeBSD, Krita 4.1 Beta, C++/Qt

  • CMake 3.12 Update on FreeBSD
    CMake 3.12 has reached rc1. That means we’re testing the update on FreeBSD, and building lots and lots of packages. And, as I’ve written previously, every CMake update triggers a bunch of interesting software findings. As a motto, I’ve got “use it, aggressively improve it” on my website (you can hire me for odd CMake and C++ jobs, too). So hitting compile issues makes me turn to fixing software outside of KDE.
  • Krita 4.1 Digital Painting Program Enters Beta With Multi-Monitor Workspace Layouts
    The KDE/Qt-aligned Krita digital painting program has published the first beta of their next feature release, Krita 4.1.
  • The day Kate Gregory enjoyed Qt
    At my company we use C++ for everything, from creating microservices to website backends and as a generator for website frontends, I mean, we do a lot of c++. And because of that we always need more c++ people, but sometimes it’s hard to find developers, but it’s easy to find php / python / javascript ones. Because of that we hired Kate Gregory’s famous c++ course – “Teaching the Teacher” to train current C++ developers to teach C++. (now, that’s a lot of ‘C++’ in a simple sentence, I know. bear with me.) For those that doens’t know, Kate Gregory is somebody that uses, advocates our beloved language even before I was born, and talks all over the world about C++ and also do trainings for companies, And so I enlisted to be her student. It was a really pleasant course going thru how to proplery explain C++ for people that know how to program but don’t know how to C++, and for that I’m grateful. But then when I commented out about Qt in the middle of the class she rolled her eyes, that made me feel a bit uneasy so I talked to her on why the eye-roll. “Qt is not c++”, and I tougth this was already settled down for years, so I asked her if she would be open to see some simple c++ code written in Qt and tell me what she thinks of it. “Well, Yes. but people already tried and it was not good”.

Red Hat: Kubernetes, 'Cloud', and GlusterFS 4.1.0 Release

  • Kubernetes StatefulSet In Action
    Recently, I stumbled upon a StackOverflow question around StatefulSets which made me wonder how well understood they are at large. So I decided to put together a simple stateful app that can be used to experiment with a StatefulSet. In this blog post we will have a closer look at this app and see it in action. If you’re not familiar with StatefulSets, now is a good time for a refresher, consulting the official docs concerning their usage and guarantees they provide.
  • The road to cloud-native applications
    As many organizations do not have the luxury of completely rebuilding their technology foundation or immediately adopting new practices and mindsets, they can embrace gradual yet fundamental shifts in culture, processes, and technology to help support greater velocity and agility. With software increasingly key to how users engage with businesses and how businesses can innovate to stay competitive, organizations should adapt to the new demands of the Digital Economy, such as speeding up application development and delivery. The cloud-native approach describes a way of modernizing existing applications and building new applications based on cloud principles, using services and adopting processes optimized for the agility and automation of cloud computing.
