  • 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.

10 Open Source Static Site Generators to Create Fast and Resource-Friendly Websites

Technically, a static website means the webpages are not generated on the server dynamically. The HTML, CSS, JavaScript lie on the server in the version the end user receives it. The raw source code files are already prebuilt, the source code doesn’t change with the next server request. It’s FOSS is a dynamic website which depends on several databases and the web pages are generated and served when there’s a request from your browser. Majority of the web is powered by dynamic sites where you interact with the websites and there are plenty of content that often change. Read more

Richard Stallman: You can get arrested without a reason

The last few months have put data protection back in the spotlight. During a crisis of this kind, do we have to choose between safety and privacy? We talked about this with Richard Stallman, digital privacy activist and the founder of the Free Software Movement. Read more

7 Amazing Linux Distributions For Kids

Linux is a very powerful operating system and that is one of the reasons why it powers a lot of servers on the Internet. Though there have been concerns about its user-friendliness which has brought about the debate of how it will overtake Mac OSX and Windows on desktop computers, I think users need to accept Linux as it is to realize its real power. Today, Linux powers a lot of machines out there, from mobile phones to tablets, laptops, workstations, servers, supercomputers, cars, air traffic control systems, refrigerators, and many more. With all this and more yet to come in the near future, as I had already stated at the beginning, Linux is the operating system for future computing. Because the future belongs to the kids of today, then introducing them to technologies that will change the future is the way to go. Therefore they have to be introduced at an early stage to start learning computer technologies and Linux as a special case. One thing common to children is curiosity and early learning can help instill a character of exploration in them when the learning environment is designed to suit them. Having looked at some quick reasons why kids should learn Linux, let us now go through a list of exciting Linux distributions that you can introduce your kids to so that they can start using and learning Linux.
