• How to install the Icinga2 Monitoring tool on Ubuntu Server 16.04

  As your data center is being populated with more and more Linux servers, you need to have the means to monitor those systems. As with anything in the open source world, there are a vast number of tools available for the task. One such tool is Icinga2, a web-based system monitor that keeps a constant check on the availability of network resources, generates real-time reporting on performance and services, and can even notify users of outages. Icinga2 also uses a RESTful API, so you can update configuration files on the fly and notifications can come by way of email, texts, or mobile messaging applications.

• Writing Up Plan B

  With the prominence of things like Liberapay and Patreon as well as Snowdrift.coop, I have had to look at the tax implications of them all.  There is no single tax regime on this planet.  Developers and other freelancers who might make use of one of these services within the F/LOSS frame of reference are frequently not within the USA frame of reference.  That makes a difference.

• Trisquel 8.0 LTS Flidas – The 100% Libre Linux OS, Using MATE & Powered By Linux-Libre 4.4

  Trisquel 8.0 is the latest release of Trisquel Linux Distribution that’s endorsed by the Free Software Foundation. this release based on Ubuntu 16.04 LTS, using MATE desktop 1.12 as default desktop environment and powered by Linux-libre 4.4 LTS kernel.

  The desktop environment shifted over to MATE as they wanted a Linux desktop not requiring OpenGL acceleration due to not wanting to require binary drivers or even binary GPU microcode files for that matter, ruling out 3D hardware acceleration for most newer GPUs.

Deja Dup is a deceptively clever tool. It looks too simple - blame Gnome for that - but it has an extensive set of options and features. In my testing, it was reliable. But then, Deja Dup can also be improved. Better and more fine-grained control of backup data (file control), better scheduling (exact times and/or conditions for when the backup ought to run), and slightly more clarity around backup retention. I am also not sure regarding encryption, and whether backup passwords actually mean exactly that. Lastly, the support for additional cloud services would be a nice thing, because there's no reason for any particular one or two to be featured and for the rest to be excluded. Duplicity does support numerous cloud platforms, there's no reason for Deja Dup to behave differently.

All that said, most Linux distributions do not promote backups well enough, and/or do not necessarily include simple and practical tools that even less skilled users can try with confidence. Ubuntu backups are not a new thing, of course, but I finally got around to testing the functionality, and I'm glad I did. This seems like a nice compromise between nothing and other, somewhat more difficult rsync frontends. Simple use, password protection and multi-location support are the main selling points. If you don't have your own robust backup mechanism in place, this is a good choice to start. Definitely worth checking out. Take care.

Dubbed the "Disco Dingo," Ubuntu 19.04 will be released next year on April 18, 2019, and will be supported for nine months, until July 2020. Its development cycle started on October 25, 2018, with the toolchain upload, and the first daily build ISO images are already available to testers.

Of course, these are based on the previous release, Ubuntu 18.10 (Cosmic Cuttlefish), which was released earlier last month on October 18, so don't expect them to have any new features or enhancements, nor to look any different than the Ubuntu 18.10 live images.

• Disco Dingo: The development cycle has started!

  The development cycle for the Disco Dingo (which will be the codename for the 19.04 release) has started for the Lubuntu team!

  As of the time of writing, the initial building blocks have been put in place for the archive, and preparations are being made for its opening. Right now, the Ubuntu Foundations Team is working on preparing a transition to Python 3.7 as the default version, as well as some GCC changes and the usual preparation work.

  For Lubuntu, this means we can begin setting up our infrastructure for the Disco Dingo in preparation for when the archive opens. Our full 19.04 release blocker list can be found here. All of these items will be completed before the planned release date of April 18, 2019. We are also working on cleaning up some 18.10 bugs post-release, so you can expect an announcement from us, either as a post here on our official Lubuntu blog or on Twitter/Mastodon.
