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.

    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

    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 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.

    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.

    Encryption-at-rest prevents an attacker from accessing encrypted data stored on the disk even if he has access to the system. The open-source databases MySQL and MariaDB now support encryption-at-rest feature that meets the demands of new EU data protection legislation. MySQL encryption at rest is slightly different from MariaDB as MySQL only provides encryption for InnoDB tables. Whereas MariaDB also provides an option to encrypt files such as redo logs, slow logs, audit logs, error logs, etc. However, both can’t encrypt data on a RAM and protect it from a malicious root.

  • How Can I Sudo Another User Without A Password? – Linux Hint

    In Linux platforms, a sudo user is a tool that implies “superuser do” to run various systems’ commands. A sudo user is typically a root user or any other user who has some privileges. To delegate important tasks like server rebooting or restarting the Apache server, or even to create a backup using the sudo command, you can use the sudo without having to enter the password again and again. By default, sudo user needs to provide some user authentication. At times, user requirements are to run a command with these root privileges, but they do not desire to type a password multiple times, especially while scripting. This is easily doable in Linux systems. In this article, we will check the method to sudo another user without entering their password.

  • How to use the sipcalc Linux command line tool | Enable Sysadmin

    The only network numbers I can keep in my head are now and always have been a Class C network with a 24-bit netmask, such as 192.168.1.0/24. I know there are 254 usable host addresses available with a broadcast address of 192.168.1.255, a gateway/router address of 192.168.1.1 or 192.168.1.254 (depending on who's running the network), and a human-readable netmask of 255.255.255.0. That's my standard network. After all, 254 hosts are enough for any subnet, right? Wrong. A few years back, I had to step outside of my standard 254 hosts per subnet scenario when I decided to use a 22-bit netmask (255.255.252.0) to get a 1022 usable address space. I knew little about this address space, and it was frustrating to try to search for the simple information that I needed without scrolling through forums with all the idle chatter and off-topic rhetoric. I guess some people just need a space in which to air their grievances about everything. I digress.

    Last week we reached out to the community at large with a simple question: What do you predict will happen in the world of Linux Gaming by the end of 2021? To make things a little more fun, we asked everyone to limit their Linux Gaming predictions to 5 items, and be as specific as possible as to what they expect to occur. We also asked everyone to work on their predictions individually to avoid any potential bias. Now, we are sharing with you all the predictions we received, from quite a few places across the world as you can see from the below map. The Linux Gaming Community knows no frontiers.

  • Team Cherry upgrade the excellent Hollow Knight with Vulkan for Linux | GamingOnLinux

    Team Cherry have given their excellent action-platformer metroidvania Hollow Knight a bit of an upgrade, which you can test out on Steam in a fresh Beta test. Not played it before? You're missing out. Hollow Knight is a classically styled 2D action adventure across a vast interconnected world. Explore twisting caverns, ancient cities and deadly wastes; battle tainted creatures and befriend bizarre bugs; and solve ancient mysteries at the kingdom's heart.

  • OpenLoco is a free and open source re-implementation of Chris Sawyer's Locomotion | GamingOnLinux

    Just like there's the awesome OpenTTD for fans of Transport Tycoon Deluxe, there's also OpenLoco for players who want to play through the classic Locomotion. Not a project we've covered here before it seems, so we're making that right today. Originally released back in 2004, it's actually a spiritual successor to Transport Tycoon but it was not as loved due to various problems with the original release. Perhaps though it can have a new life thanks to OpenLoco.

  • VRWorkout is a free and open source VR fitness rhythm game

    Well, that's certainly one way to get a bit more exercise in. Whatever helps right? No judgement here, I could probably do with a little more myself… It's built with the free and open source game engine Godot Engine, so not only is the source code open for the game itself it's properly open for anyone to put it together from the source and will remain so. Speaking about VRWorkout to us on Twitter, the developer mentioned they actually do develop for it on Linux but they use a Quest headset not supported on Linux so they have to work with that on Windows. Perhaps though, in time, Monado might break down that barrier.

  • Free and open source voxel game engine Minetest 5.4 is out, makes mods easier for users | GamingOnLinux

    Minetest, the Minecraft-like voxel game engine (and a basic game that comes with it) has a big new release out with Minetest 5.4.0 and it's worth trying again. As we covered before during the Release Candidate stage, one of the big features for users in this release is vastly easier modding with both small mod packs and entire games. Minetest had a way to browse and download them all directly in the game for a while, but now it will also actually download all the dependencies mods need - making it vastly easier to get what you want and then into a game. No more downloading one mod, then finding all the individual bits it needs.

GNOME 40 Beta Released for Public Testing, Here’s What’s New
