A side-by-side comparison of MongoDB and Cassandra databases

Filed under
Server
OSS

They're both databases, obviously. More importantly, they are both examples of NoSQL databases. NoSQL is a type of database architecture in which data is stored in a relatively unstructured fashion. Compared to more traditional SQL-style databases, NoSQL can be a more efficient way of storing the large quantities of unstructured data that organizations commonly use for big data operations.

MongoDB and Cassandra are also both open source -- although commercial implementations are available, too. But even in that respect, they are not identical. MongoDB is governed by GNU Affero General Public License 3.0, whereas Cassandra is subject to Apache License 2.0.

  • Microsoft Promises Not to Sue Over GPLv2 Compliance Issues [Ed: Weird (almost white-washing) headline given that Microsoft has been caught in violation of the GPL many times before]
  • New partners join open source ship design platform
  • Management alone can't drive open culture change

    It would seem that targeted learning around how a non-hierarchical governance model practically works in a global organisation is required. This, in and of itself, is a learning expedition that needs to be highly personal. We have to be retrained to fail forward and without fear. We have to learn to criticize constructively, even our bosses. We also have to rethink things like typical management activities, job security and career pathways. Above all, we have to feel safe inside our organizations and that requires trust.

FOSS Licensing: Good Compliance Practices and "Do I Have to Use a Free/Open Source License?"

  • Good Compliance Practices Are Good Engineering Practices

    Companies across all industries use, participate in, and contribute to open source projects, and open source compliance is an integral part of the use and development of any open source software. It’s particularly important to get compliance right when your company is considering a merger or acquisition. The key, according to Ibrahim Haddad, is knowing what’s in your code, right down to the exact versions of the open source components.

  • Do I Have to Use a Free/Open Source License?

    That, as we all probably already know, is not the case. The only licenses that can be called "open source" are those that are reviewed and approved as such by the Open Source Initiative (aka OSI). Its list of OSI-Approved licenses allows developers to choose and apply a license without having to hire a lawyer. It also means that companies no longer need to have their own lawyers review every single license in every piece of software they use. Can you imagine how expensive it would be if every company needed to do this? Aside from the legal costs, the duplication of effort alone would lead to millions of dollars in lost productivity. While the OSI's other outreach and advocacy efforts are important, there's no doubt that its license approval process is a service that provides an outsized amount of value for developers and companies alike.

Cloud.gov Open-Source Platform Speeds Development, Requirements Process

Filed under
OSS

IT development in the federal government has earned its reputation for being a painfully slow process but Cloud.gov, the government’s cloud application platform, is helping to change that by standardizing the application lifecycle and helping to document it every step of the way.

The need to document the entire stack of an IT solution in the federal government can run up to 1,000 pages, and that process requires in depth knowledge of thousands of pages of regulations, laws and risk management policies.

Typically, federal agencies have compliance experts who must review this documentation and grant approval or request changes. This can take six to 14 months to get authority to operate (ATO), and then you still need to deploy the application.

GitHub’s tool reduces open source software license violations

Filed under
OSS

GitHub has open-sourced its Licensed tool, a Ruby gem that caches and verifies the status of license dependencies in Git repos.

Licensed has helped GitHub engineers who use open source software find potential problems with license dependencies early in the development cycle. The tool reports any dependencies needing review.

OSS

"The Real Activist" slated for release this summer will include an interview with Brent Turner of OSI Affiliate Member CAVO, as well as coverage of the groups work to promote open source software within US elections' voting systems. The documentary highlights Turner's efforts and CAVO's mission to secure the United States election systems through GPL licensed open source software. Famed narrator Peter Coyote also stars in the film along with former CIA Director R. James Woolsey and many political notables.

SUSE Launches Beta Program for SUSE Linux Enterprise High Performance Computing

While SUSE is working hard on the major SUSE Linux Enterprise 15 release, they recently announced that the SUSE Linux Enterprise High Performance Computing (HPC) platform is now a dedicated SUSE Linux Enterprise product based on SUSE Linux Enterprise 15, available for public testing on 64-bit and ARM 64-bit architectures. SUSE Linux Enterprise 15 will introduce numerous new features and improvements, including a brand new installer that offers a single unified method to install one of the supported SUSE Linux Enterprise products, including the SUSE Linux Enterprise High Performance Computing module, which comes with a set of components used in high-performance computing environments.

Programming: ThreadStack and Qt for WebAssembly

  • ThreadStack: Yet Another C++ Project Trying To Make Multi-Threading Easier
    ThreadStack is yet another C++ project trying to make it easier dealing with multiple CPU threads. This latest open-source C++ threading project comes out of academia research. ThreadStack is self-described by its developer, Erkam Murat Bozkurt, as "an innovative software which produces a class library for C++ multi-thread programming and the outcome of the ThreadStack acts as an autonomous management system for the thread synchronization tasks. ThreadStack has a nice and useful graphical user interface and includes a short tutorial and code examples. ThreadStack offers a new way for multi-thread computing and it uses a meta program in order to produce an application specific thread synchronization library." Erkam has been working the rounds trying to raise awareness for this research on the GCC and LLVM mailing lists.
  • Beta for Qt for WebAssembly Technology Preview
    WebAssembly is a bytecode format intended to be executed in a web browser. This allows an application to be deployed to a device with a compliant web browser without going through any explicit installation steps. The application will be running inside a secure sandbox in the web browser, making it appropriate for applications that do not need full access to the device capabilities, but benefits from a swift and uncomplicated installation process.
  • Qt for WebAssembly Tech Preview Reaches Beta
    As part of next month's Qt 5.11 tool-kit update, a new technology preview module will be WebAssembly support for running Qt5 user-interfaces within your web-browser.

Kernel and Graphics: BUS1, Linux 4.17 RC2, Wayland's Weston and Mesa

  • BUS1 Still Remains Out Of The Mainline Linux Kernel, But DBus-Broker Continues
    The BUS1 in-kernel IPC mechanism born out of the ashes of KDBUS still hasn't been mainlined in the Linux kernel, but its code is still improved upon from time to time. At least though DBus-Broker as a new performance-oriented D-Bus implementation continues gaining ground in user-space. DBus-Broker was announced last year as a new message bus implementation of D-Bus focused on high performance and reliability while continuing to offer compatibility with the original D-Bus implementation.
  • Linux 4.17-rc2 Kernel Released With Mostly Routine Changes
    Linus Torvalds has announced the availability of the second weekly test release for what is becoming the Linux 4.17 kernel.
  • Wayland's Weston Gets Optimizations For Its Pixman Renderer
    Wayland's Weston reference compositor with its Pixman software-based renderer back-end has received a number of performance optimizations. Fabien Lahoudere of Collabora posted a set of patches today to optimize the Pixman renderer for Weston. In particular, there are optimizations around compositing damage to the screen as well as optimizing the shadow buffer usage. The Weston Pixman renderer is often used as a software accelerated fallback in cases where no GPU hardware acceleration may be available. As implied by the name, it uses the long-standing Pixman library that is also used by Cairo, the X.Org Server, etc, for pixel manipulation on the CPU.
