How to get your SUSE Box to do octave sounds on shutdown

Howtos

One of the things i like most about (gnu/?) linux, other than everything, is how you can get it to do things you never knew you wanted… and that’s what i’m all about, i like to dig down the stuff that creates the WOW-effect, even if it has little or no purpose at all. Being able to convert 8 friends so far, makes me certain that these things really do work on a psychological level.

Julia v1.5.0 has been released

Thank you to everyone who made this year’s JuliaCon great! As a parting gift, the Julia developers are pleased to announce the release of Julia v1.5.0, the fifth minor release in the 1.x series. Jeff and Stefan put together a blog post highlighting some of the most exciting new features in 1.5. Check it out! As usual, binaries are available for all of your favorite platforms (Linux, macOS, Windows, and FreeBSD) at https://julialang.org/downloads. As a minor release, v1.5.0 contains no breaking changes, only new features, performance improvements, and marginal, undisruptive changes in behavior. You can also see the NEWS file for the full set of changes. Note that like 1.5, like its predecessor 1.4, does not have long term support. As of this release 1.4 has been effectively superseded by 1.5, which means that there will not likely be any further 1.4.x releases. Julia 1.0 is still currently the only long term support version. We encourage everyone to give it a try. Packages can test with 1.5.0 on CI by specifying 1.5 on Travis, AppVeyor, Cirrus, and GitHub Actions. As always, let us know in the issue tracker if you run into any issues. Read more Also: Julia 1.5 has been released

Meet Super Container OS, a Debian-Based Live Distro with a Built-In Container Engine

I told you I love new projects, right? Well, today I have a brand-new distro that I’d like to introduce you to, called Super Container OS, and targeted at developers who want to run containerized apps. The Super Container OS developer Harshad Joshi pinged me earlier on Twitter earlier to check out his new distro, which he says it’s a live and installable Linux OS that comes pre-loaded with a container engine powered by Docker and systemd-nspawn. Based on the Bufferstack.IO computing platform, Super Container OS wants to be the ideal tool for those who want to create, deploy and distribute apps that can run on IIoT Gateways, servers, or even virtual machines. Now that Container Linux from CoreOS is no more, I guess we need more alternatives. Super Container OS is based on the latest Debian GNU/Linux 10 “Buster” operating system series and aims to make deploying, running and managing containerized applications easier by using OS level virtualization.

  • Stretchly – reminder to take breaks

    Many people who regularly use computers suffer from eye strain and fatigue. Looking at a monitor for a long time can strain your eyes or can make any other problems you are having with your eyes seem more apparent. There are lots of simple steps you can take to reduce eye strain and fatigue. These include adjusting the brightness, contrast settings, and text size displayed, as well as minimizing glare, and ensuring your room has proper lighting. Taking regular breaks is also very important. This is where Stretchly is designed to help. Stretchly is a cross-platform open source app that reminds you to take breaks when working with your computer.

  • Vesta Control Panel – Simple Yet Powerful Control Panel For Linux

    cPanel web hosting is easier to set up and manage. Users who are not familiar with Linux servers can easily maintain servers using cPanel, a GUI control panel for web servers. Buying shared hosting or managed web hosting can provide users a control panel. But both types of hostings have their own advantages and disadvantages. Read this article to know things to remember before buying web hosting. In this Linux cPanel series, I am discussing the best open source alternatives of cPanel. Most of the open-source alternatives of cPanel are free. Today in this article, I am going to talk about Vesta Control Panel, a free and open-source control panel for Linux servers. Vesta CP can be deployed on Red hat/CentOS (version 5,6,7), Debian (version 7, 8, 9), and Ubuntu (version 12.04 – 18.10).

  • The Best Photoshop Alternatives That Are Totally Free

    GIMP (Gnu Image Manipulation Program) is usually the default go-to alternative for anyone looking for Photoshop-level capabilities in a freeware desktop program. It’s not quite as feature-rich as Adobe’s powerhouse, but it comes with an impressive stack of tools nevertheless — and while it can be bewildering for first-timers, it shouldn’t take you too long to learn the ropes.
