      • digiKam 7.6.0 is released


        After one month of active maintenance and another huge bug triage, the digiKam team is proud to present version 7.6.0 of its open source digital photo manager. See below the list of most important features coming with this release.

        Long time ago, the AppImage packaging suffered from an important lack of International Components for Unicode (ICU) support. Typically, digiKam and Showfoto deal with the string internally using Qt, but the framework was not compiled with the ICU library to handle properly all string encoding used over the world.

      • TubstaNative IPv6 with OpenBSD and Aussie Broadband

        We are coming on two decades since IPv6 became a recognised standard and generally available but it is still not being widely adopted by people and organisations that have easy access to IPv4 address space. Even if you have a native IPv4 address, it will typically be in the form of some CG-NAT or other NAT on your customer premises equipment (CPE).

        Things work so much better when they have a dedicated, routable IP address, especially when they don’t need to share a state table with other connections.

      • Its FOSSHow to Install and Use FileZilla on Ubuntu Linux

        If you ask the geeky sysadmins, they will swear by rsync or scp commands for transferring files between remote server and local system.

        However, those are command line methods and not everyone feels comfortable.

        Thankfully, there are some GUI tools available that let you transfer files to or from the remote servers.

        FileZilla is a popular, cross-platform, open-source tool for this purpose. It supports transferring file using FTP over TLS or SSL (FTPS) and also FTP over SSH (SFTP) along with old FTP protocol.

      • Tom’s HardwareHow To Change File or Directory Permissions in Linux | Tom’s Hardware

        If you’ve ever tried to run a script from the command line in Linux and gotten an error message saying that it’s not executable or attempted to enter a directory only to be blocked by the system, you probably don’t have permissions to do those things. Fortunately, if you have the proper rights or the ability to act as a super user (accessible by using sudo), you can change the permissions on files and directories.

        In this how-to we’ll look at the chmod command, a powerful command that can change file and directory permissions for the owner, user group members and others. In a section below, we’ll also explain how to tell what group your user is in and exactly what Linux means by “others.”

        Whilst you become accustomed to these commands it’s good to work with example empty files and directories and you should take extra care to ensure you are carefully following the instructions.

        All the commands in this how-to will work on most Linux machines. We’ve used a Ubuntu 20.04 install but you could run this how-to on a Raspberry Pi. All of the how-to is performed via the Terminal. You can open a terminal window on most Linux machines by pressing ctrl, alt and t.

      • The National Science Foundation bets big on open source


        The NSF is an independent agency of the United States government and the premier funding agency for fundamental research and education in all non-medical fields of science and engineering. They are now major open source supporters as well. To be fair, the National Institutes of Health (NIH), which funds medical research in the United States, is also already a big fan of open source with the first open-access mandate and even an open source 3-D Printing Exchange made famous during the pandemic.

        With PEOSE, the NSF hopes to harness the power of open source development for the creation of new technology solutions to problems of national and societal importance. Existing NSF-funded research projects already result in publicly accessible, modifiable, and distributable open source software or data platforms and now even open hardware that catalyzes further innovation. Open source savings for scientists are large. The return on investment (ROI) for funders of open source development (100s-1,000s% after only a few months) is frankly too high to ignore. The NSF wants to follow the best examples of open source development where the product is widely adopted and forms the foundation of a self-sustaining open source ecosystem (OSE). A distributed community of developers and a broad base of users across academia, industry, and government make up these OSEs. Think Linux for software, Arduino for electronics, or RepRap for manufacturing hardware.

        • Eric RescorlaUnderstanding The Web Security Model, Part I: Web Publishing

          Like many pieces of technology, the Web is one of those things that people are perfectly happy to use but have absolutely no idea how it works.[1] It’s natural to think of the Web as a publishing system, and at some level it is: the Web lets people publish documents for anyone to read. But what the Web really is is a distributed computing platform that lets Web sites run code on your computer.[2] Originally, of course, that code just rendered documents, but now it’s used for everything from documents (like the one you’re reading now) to text-based applications like Slack or even videoconferencing apps like Google Meet. Unsurprisingly, then, the Web has a unique security model, which is the topic of this series of (some unknown number of) posts.

          I meant to start right in on security but then I realized I first needed to provide enough background of how the Web works to have the security stuff make sense. This post is the first half of that background material, covering the structure of Web sites and pages. There will be a second post that covers Web “applications”. This isn’t a textbook or a specification, so I don’t intend to provide a complete picture; the idea here is to cover the essential elements for understand the security model.

        • Remy Van ElstQt 5.15.3 Open Source released

          Qt is a nice C++ framework with a GUI toolkit on top, actually, 2 toolkit, Widgets and Qml. Qt is available under the GPL and LPGL, open source licenses and a closed source license. Back in 2020, the Qt company decided to start a war against their own users and contributors by withholding the 5.15 code, only releasing them under a closed license, making the offline installers available to paid customers and requiring a Qt account for the online installer. Due to an agreement with the KDE project they are obliged to release the code after one year under an open source license, and that time has come for 5.15.3. For most LTS releases, the Qt company writes a blog post, but this open source release only gets a mailing list post (One day and 4 blog posts later, no mention of 5.15.3 on their blog). This short post is intended to give a bit more publicity to that release and to tell you about the KDE Qt 5.15 LTS patch collection. Even if I might not agree with the business practices, the framework is nice to work with.

            I’m currently working on a project comparing different CI/CD pipelines, trying to get a better idea of what each offers, how they run, and how much it takes to get them set up. My first stop was CircleCi.

            If you’re looking for a reliable CI/CD platform to deploy your Python Django project, CircleCi offers a lot. It’s easy to set up, comes with tons of reusable set ups called Orbs, and best of all, offers up to 6,000 build minutes per month for free.
