    In this video, I am going to show an overview of Netrunner 19.08 Indigo and some of the applications pre-installed.

  • How to use the LXD Proxy Device to map ports between the host and the containers

    LXD supports proxy devices, which is a way to proxy connections between the host and containers. This includes TCP, UDP and Unix socket connections, in any combination between each other, in any direction. For example, when someone connects to your host on port 80 (http), then this connection can be proxied to a container using a proxy device. In that way, you can isolate your Web server into a LXD container. By using a TCP proxy device, you do not need to use iptables instead.

    There are 3³=9 combinations for connections between TCP, UDP and Unix sockets, as follows. Yes, you can proxy, for example, a TCP connection to a Unix socket!

  • Management of snaps in a controlled, enterprise environment

    Few enterprises want all their computing devices to be fully exposed to the internet. In an environment of ever-growing security threats, isolating internal networks from the wider internet is not simply best practice, but borderline essential.

    However, with all the benefits that restricted networks provide, it can pose challenges for enterprises who are looking to take advantage of certain technologies. One of these is the automatic update feature of snaps which enable a low-friction process and a fast release cadence. If an enterprise has a restricted network, then this will prevent snaps being able to automatically update due to the necessity for an external internet connection and potentially upsetting change management policies.

  • Dominique Leuenberger: openSUSE Tumbleweed – Review of the week 2019/3

    Seems we’re settling at 3 snapshots per week. It seems to be pretty hard at the moment to get stagings fully built and tested (build are constrained by only few workers able to build e.g. Firefox, and since Leap started the dev cycle, the load on OBS and those few workers massively increased). So, 3 snapshots, or roughly one every other day, does not sound so bad overall. During this week, we released  0829, 0902 and 0904.

  • Improved Common Agricultural Policy compliance with publicly available and user-generated data

    The open source RECAP platform is currently available under the GNU General Public License. The remote sensing components are also market-ready. Both can be hosted either on project partners' servers or on the client's own servers.

Linux As An Alternative To Windows & MacOS

I downloaded Mandrake Linux and installed it onto my computer and tried it. It had a familiar-looking desktop, not exactly like windows but not too alien from it either. It contained some useful software including a web browser, email program, office suite, etc, and I loved trying something truly different. The problem I found though, it was too difficult to download new programs and to customise the user experience. It had a command-line interface meaning you needed to type computer code to download programs or change the system to your liking. Although it looked familiar, to use it on a day-to-day basis, a certain amount of coding knowledge was required. I wanted to use my computer to be productive rather than learning to code to use it. Although this experiment was enjoyable, at this stage Linux just wasn’t for me. Read more

  • What is Raspberry Pi 4 “Model B”? [Ed: I'm still waiting for them to formally apologise for going behind customers' backs, making secret deals with Microsoft to put Microsoft malware on all those devices]

    Raspberry Pi has conquered the world of SoC (System on a Chip). It has already garnered millions of followers since its release in 2012. Not only is it inexpensive, but it’s also versatile, modular, and multi-purpose. It has become popular not only as a credit-sized computer board but also as a controller in electronic, robotics, and IoT projects. The size, features, and price drive the popularity of the Pi, especially in the DIY community. To keep up with the current technological trends, the tiny board has undergone plenty of upgrades over the years, and there have been many varieties so it can cater to the needs and demands of its users. In 2019, the Raspberry Pi Foundation released the fourth generation of the multi-purpose board, the Raspberry Pi 4 B. It is the most powerful Pi to date, sporting huge upgrades from its predecessors. The compact board is touted to deliver a PC-level performance, and it didn’t disappoint.

  • Kentaro Hayashi: Grow your ideas for Debian Project

    There may be some "If it could be ..." ideas for Debian Project. If idea is concreate and worth to make things forward, it should make a proposal for Project Funding. [...] I'm not confident whether mechanism works, but Debian needs change.

  • Sam Thursfield: Calliope, slowly building steam

    There are some interesting complexities to this, and in 12 hours of hacking I didn’t solve them all. Firstly, Bandcamp artist and album names are not normalized. Some artist names have spurious “The”, some album names have “(EP)” or “(single)” appended, so they don’t match your tags. These details are of interest only to librarians, but how can software tell the difference? The simplest approach is use Musicbrainz, specifically cpe musicbrainz resolve-ids. By comparing ids where possible we get mostly good results. There are many albums not on Musicbrainz, though, which for now turn up as false positives. Resolving Musicbrainz IDs is a tricky process, too — how do we distinguish Multi-Love (album) from Multi-Love (single) if we only have an album name? If you want to try it out, great! It’s still aimed at hackers — you’ll have to install from source with Meson and probably fix some bugs along the way. Please share the fixes!

  • Neovide Is A Graphical Neovim Client Written In Rust

    Neovide is a really cool GUI client for Neovim. Although it essentially functions like Neovim in the terminal, Neovide does add some nice graphical improvements such as cursor animations and smooth scrolling. It even has me thinking about making it my new "vim" alias.

Linux 5.11.13, 5.10.29, 5.4.111, 4.19.186, 4.14.230, 4.9.266, and 4.4.266

Get involved with Mageia, become a Packager

With Mageia 8 just released and development for Mageia 9 getting underway in Cauldron, the unstable branch of Mageia, now is a great time to get involved with packaging. We are starting to look at the features that we want to include for Mageia 9, and as it is so early in the development cycle, now is the time for major developments, or big updates to key pieces of software. This is a great time to join the project as you can propose features you would like to see, help to implement large changes or see how a distribution evolves through development, stabilisation and then is released. If there is an application that you are interested in, if you want to help maintain part of the distribution, or if you want to learn something new, there are many opportunities to do so with the packaging team.
