GNUnet 0.11.5 released

Filed under
GNU

We are pleased to announce the release of GNUnet 0.11.5.

This is a bugfix release for 0.11.4, mostly fixing a few minor bugs and improving performance, in particular for identity management with a large number of egos. In the wake of this release, we also launched the REST API documentation. In terms of usability, users should be aware that there are still a large number of known open issues in particular with respect to ease of use, but also some critical privacy issues especially for mobile users. Also, the nascent network is tiny (about 200 peers) and thus unlikely to provide good anonymity or extensive amounts of interesting information. As a result, the 0.11.5 release is still only suitable for early adopters with some reasonable pain tolerance.

  • CNCF to Expand Scope of SIGs

    The Cloud Native Computing Foundation announced at the KubeCon + Cloud Native + Open Source China Summit today that it is expanding the number of special interest groups (SIGs) surrounding Kubernetes, as part of an effort to accelerate development of critical complementary technologies.

    Dan Kohn, executive director for the CNCF, says it’s become apparent that the nine members of the technical oversight committee (TOC) for Kubernetes needs to be supported with expertise in specific areas. The first two SIGs to be formed will be focused on security and storage, followed by SIGs addressing network traffic, observability, governance, application delivery, core and applied architectures.

    [...]

    Kohn says as part of this initiative, one of the goals of the CNCF is to entice more developers to contribute to an increasing number of open source projects. Kohn estimates that well more than half the developers who leverage open source software don’t contribute to any project. Many of those developers are already creating forks to open source code every time they patch open source software on their own. Every time that software is updated—otherwise known as carrying your own patch—those developers have to reconstruct that patch. That issue would go away if the developers contributed their patches to the open source project, which would then ensure the issue is addressed as part of the life cycle of the project, he notes.

  • Wind River Becomes First to Achieve OpenChain 2.0 Conformance

    Wind River®, a leader in delivering software for critical infrastructure, today announced that it is certified on OpenChain version 2.0. It was also the first company to become OpenChain conformant.

  • How SNIA is using Open Source to speed up storage standards

    Developing a storage standard has always been a long, arduous and contentious process. It is the same for most standards.

    However, with the speed that technology is changing, that approach is no longer sustainable, and not just for storage. To understand what change means for the storage industry, Enterprise Times talked with Richelle Ahlvers.

    Ahlvers is a board member at the Storage Networking Industry Association (SNIA). She is also the Chair of the Scalable Storage Management Technical Workgroup. That workgroup is responsible for the Swordfish Storage Management API. Already providing support for block and file storage, it will release support for object storage soon.

    [...]

    Another example that Ahlvers gave is the SNIA work on the CDMI (Cloud Data Management Interface). That spec is now entirely in Open Source. All the bug fixes and changes are done through the Open Source community which, Ahlvers says, makes it faster.

    Software is at the heart of the digital revolution and, ultimately, it is what determines the success, agility and competitiveness of businesses looking to succeed in today’s fast paced, digital world.

    Open source is changing the way organisations build software, offering a strong and critical foundation for digital transformation, while bringing teams and departments together. As the approach to in-house software development evolves, organisations understand that their success is determined by the way they participate in Open Source Software (OSS). This offers a realm of opportunities that do not just benefit the IT department, but the business at large.

  • The financial services industry is the next great frontier for open source

    Open source software is a driver of the democratization of technology, opening doors, and leveling the playing field for many industries. However, financial services has been a rare exception: financial institutions have tended to rely on their own technology development and operation.
    In a sector that has traditionally served the few and not the many, open source could be the key to make financial services more inclusive for the 2 billion people and 200 million small businesses around the world lacking access to basic services such as banking and lending.
    In a report published by Gartner, global enterprise IT spending in the banking and securities market was estimated to have grown by 4.6% in 2018 in constant US dollars. Banking and securities firms remain steadfast as they continue to prioritize digital transformation. But it has largely been major global banks that have the resources and ability to throw their hats into the ring of technology development—smaller regional banks have tended to stay on the sidelines.

  • Should you be banking on open source analytics?

    Banks see open source as a hotbed of innovation – and a governance nightmare. Do the rewards outweigh the risks? Open source software used to be treated almost as a joke in the financial services sector.

    If you wanted to build a new system, you bought tried and tested, enterprise-grade software from a large, reputable vendor. You didn’t gamble with your customers’ trust by adopting tools written by small groups of independent programmers. Especially with no formal support contracts and no guarantees that they would continue to be maintained in the future.

    Fast-forward to today, and the received wisdom seems to have turned on its head. Why invest in expensive proprietary software when you can use an open source equivalent for free? Why wait months for the official release of a new feature when you can edit the source code and add it yourself? And why lock yourself into a vendor relationship when you can create your own version of the tool and control your own destiny?

  • Algorand, a Dapp Analytics Suite, Goes Open Source

    Algorand, a permission-less, proof-of-stake blockchain and technology company, announced that their node repository is now open source.

    The blockchain’s nodes are run by diverse entities — businesses, individuals, and consortiums — spread across many countries, according to the company website. The decentralized voting mechanism pools and randomly selects these users to develop a unique committee to approve every block.

  • [Old] On Usage of The Phrase "Open Source"

    It is unfortunate that for some time the Open Source Initiative deprecated Richard Stallman and Free Software, and that some people still consider Open Source and Free Software to be different things today. I never meant it to be that way. Open Source was meant to be a way of promoting the concept of Free Software to business people, who I have always hoped would thus come to appreciate Richard and his Free Software campaign. And many have. Open Source licenses and Free Software licenses are effectively the same thing.

  • Open Source Processors: Fact Or Fiction?

    Open source processors are rapidly gaining mindshare, fueled in part by early successes of RISC-V, but that interest frequently is accompanied by misinformation based on wishful thinking and a lack of understanding about what exactly open source entails.

    Nearly every recent conference has some mention of RISC-V in particular, and open source processors in general, whether that includes keynote speeches, technical sessions, and panels. What’s less obvious is that open ISAs are not a new phenomenon, and neither are free, open processor implementations.

The idea behind all of them is to utilize knowledge extracted from millions of existing chip designs to make chip engineering more affordable and predictable.

  • 4 great Java-based CMS options

    OpenCms has been around since 1999, and it's been an open source Java CMS platform since 2001. Not only is it one of the oldest Java-based CMS platforms, it's one of the oldest CMS tools, predating the popular PHP-based WordPress, which debuted in 2003.

    From a developer's perspective, OpenCms is simple to set up and maintain. It runs as a Java servlet, which makes installation easy. It works with most major databases; whether you prefer MySQL, Microsoft SQL Server, MariaDB or another popular database, you can likely run OpenCms without much hassle.

    OpenCms probably won't win awards as the most elegant or attractive Java-based CMS. The interface was overhauled in 2019, but OpenCms doesn't exactly feel modern. It works, but it's a little clunky.

    However, OpenCms does enjoy the distinction as a truly cost-free open source Java CMS. There is no freemium pricing model for the product, and there are no licensing fees.

Inside KDE: leadership and long-term planning

Based on my post about KDE’s anarchic organization and the micro-not-macro nature of my This Week in KDE series, you would be forgiven for having the impression that KDE is directionless and has no leadership or long-term planning capabilities. In fact the opposite is true, and I’d like to talk a bit about that today, since this information may not be obvious to users and the wider community. Now, since KDE is so vast, I can only provide my personal perspective based on the projects I’m most heavily involved in: the VDG, Plasma, and a few apps. [...] KDE doesn’t lack for strategic long-term goals and direction, so I think that part can be pretty solidly marked as a success. As for tactical leadership and direction within and between individual projects, I also think things are pretty rosy overall. KDE’s maintainer-led projects generally have excellent maintainers. The variety of KDE apps using this model model is a testament to how successful it can be with a high-quality maintainer–especially our professional-class apps like Krita. And in my opinion, KDE’s council of elders projects also have very good leadership today Read more

    Linux operating system, which is a clone of UNIX, is developed to handle multiple users with multi-tasking features. This means than more than one user can work in this operating at the same time when the computer is attached to a network or Internet. The remote users can connect with the computer that contains the Linux operating system through SSH and work on the system. It is very important to maintain security when multiple users work in the same operating system at the same time. Many built-in security features exist in the Linux operating system that can be used when local or remote access is granted from different users. The Linux users have to understand the concept of file permissions and the ownership of the file to provide security at the file system level. How the Linux users can view and modify the permissions, and the ownership of the file and folders is shown in this article.

  • How To: Simple HTTP Server with Python

    When building new infrastructure elements and deploying servers, quite often you need to test firewall rules before the rest of application stack is deployed. The basic tool of my choice here is curl which is great to testing TCP connections. But it has an important dependency: you actually need to have something listening on the other end of the connection you’re testing. If there’s no software running and servicing the port you specify, you will receive an error. Traditionally there have been small programs or scripts you’d write - first (many years ago now) in C, later in Perl. They would imply that you have to bring your test code or compiled binary to the server you need to test. Today I’d like to share a super easy way to start a basic HTTP server with Python - it’s literally just one line that will work in most cases since Python is now ubiqutous enough to be installed by default in most Linux distributions.
