Rolling release vs. fixed release Linux

Filed under
GNU
Linux

A rolling-release Linux is one that's constantly being updated. To some of you, that will sound a lot like DevOps' idea of continuous deployment. You'd be right in thinking so. In both cases, the idea is that users and developers are best served by giving them the latest updates and patches as they're created.

There are several ways of doing this. One is to deliver frequent, small updates, which is the model that Arch Linux uses. Another is to replace an old image of the operating system or program with a new one as changes are added to the software. Ubuntu Core is taking this approach.

Linux

This concept builds further upon the socket activation. When restarting a service, systemd can push the used sockets/file descriptors of that service to the sytemd daemon and pass it again to the service once it restarted. This way, no sockets/fd's are lost.

Linux Mint 17.1 Is As Good As It Gets

Filed under
Linux

Linux Mint 17.1 is the latest version of Linux Mint and has been available for a few months now.

The title of this article is "Linux Mint 17.1 Is As Good As It Gets" and as far as computing goes on a traditional laptop with a traditional style user interface this is definitely true.

I first tried Linux Mint at version 12 and it was fine enough but the Linux Mint developers have been perfecting this distribution for a number of years and now it is flourishing.

This review is going to look at all of the features of Linux Mint that the average user might be interested in as well as the new features that have been added for 17.1.

Raspberry Pi 2 review – not all the same

Filed under
Linux
Reviews

We’ll be honest, when the Raspberry Pi 2 hit our desk in mid- January we were very excited to crack it open and try it out. From what we had been told this was basically the Raspberry Pi everyone had ever wanted, at least in terms of power. It was a bit of a have-your-cake-and-eat-it moment though, as we hooked up the board that was essentially a Model B+ and began using a very familiar Raspbian layout.

It worked fantastically well; while performing normal computer actions there was none of the classic slowdown the Pi used to get. We could upgrade the system and comfortably do other tasks such as web browsing or even word processing. Simple yet appreciated, and on the surface that’s really about it for the Raspberry Pi 2. There is no real killer feature of the updated Raspbian that we can point to that illustrates the new Pi’s full abilities.
However, this is frankly a great thing. The Raspberry Pi Foundation’s mission has always been education, and with the amount of excellent tutorials and software that already exist for the Raspberry Pi, making the Pi 2 very different would make the last three years of work obsolete.

4 Useful Cron Alternatives For Linux

Filed under
GNU
Linux

For those who are familiar with the Unix system, you will also be familiar with the cron application that allows you to schedule and automate tasks to run on their own. We even have tutorials that show you how to get started with cron and crontabs. However, cron is not perfect, as it requires your system to be running 24 hours a day. If you have a habit of turning off your computer at night, and a cron job is scheduled in the sleeping hours, the task won’t be executed. Luckily, there are several cron alternatives that can do a better job than cron. Let’s check them out.

Many Linux and open source leaders gave presentations at LinuxConf.Au 2015 a few weeks ago, including Linux Creator Linus Torvalds. All of the conference videos are available on YouTube, and there were many excellent presentations -- so many it would be impossible to watch them all. The range of topics covered everything from open source governance and community management, to inspiring uses of Linux and open source technologies, to technical talks and tutorials. Here are ten interesting technical talks focused on Linux and the kernel. (Disclaimer: I have not watched every single minute of all of these videos. I'll leave it to you to decide how captivating they are.)

OpenSUSE fonts – The sleeping beauty guide

Pandora’s box of fonts is one of the many ailments of the distro world. As long as we do not have standards, and some rather strict ones at that, we will continue to suffer from bad fonts, bad contrast, bad ergonomics, and in general, settings that are not designed for sustained, prolonged use. It’s a shame, because humans actually use computers to interface with information, to READ text and interpret knowledge using the power of language. It’s the most critical element of the whole thing. OpenSUSE under-delivers on two fonts – anti-aliasing and hinting options that are less than ideal, and then it lacks the necessary font libraries to make a relevant, modern and pleasing desktop for general use. All of this can be easily solved if there’s more attention, love and passion for the end product. After all, don’t you want people to be spending a lot of time interacting, using and enjoying the distro? Hopefully, one day, all this will be ancient history. We will be able to choose any which system and never worry or wonder how our experience is going to be impacted by the choice of drivers, monitors, software frameworks, or even where we live. For the time being, if you intend on using openSUSE, this little guide should help you achieve a better, smoother, higher-quality rendering of fonts on the screen, allowing you to enjoy the truly neat Plasma desktop to the fullest. Oh, in the openSUSE review, I promised we would handle this, and handle it we did! Take care. Read more

Direct Rendering Manager and VR HMDs Under Linux

  • Intel Prepping Support For Huge GTT Pages
    Intel OTC developers are working on support for huge GTT pages for their Direct Rendering Manager driver.
  • Keith Packard's Work On Better Supporting VR HMDs Under Linux With X.Org/DRM
    Earlier this year Keith Packard started a contract gig for Valve working to improve Linux's support for virtual reality head-mounted displays (VR HMDs). In particular, working on Direct Rendering Manager (DRM) and X.Org changes needed so VR HMDs will work well under Linux with the non-NVIDIA drivers. A big part of this work is the concept of DRM leases, a new Vulkan extension, and other changes to the stack.

Software: Security Tools, cmus, Atom-IDE, Skimmer Scanner

  • Security Tools to Check for Viruses and Malware on Linux
    First and foremost, no operating system is 100 percent immune to attack. Whether a machine is online or offline, it can fall victim to malicious code. Although Linux is less prone to such attacks than, say, Windows, there is no absolute when it comes to security. I have witnessed, first hand, Linux servers hit by rootkits that were so nasty, the only solution was to reinstall and hope the data backup was current. I’ve been a victim of a (very brief) hacker getting onto my desktop, because I accidentally left desktop sharing running (that was certainly an eye opener). The lesson? Even Linux can be vulnerable. So why does Linux need tools to prevent viruses, malware, and rootkits? It should be obvious why every server needs protection from rootkits — because once you are hit with a rootkit, all bets are off as to whether you can recover without reinstalling the platform. It’s antivirus and anti-malware where admins start getting a bit confused. Let me put it simply — if your server (or desktop for that matter) makes use of Samba or sshfs (or any other sharing means), those files will be opened by users running operating systems that are vulnerable. Do you really want to take the chance that your Samba share directory could be dishing out files that contain malicious code? If that should happen, your job becomes exponentially more difficult. Similarly, if that Linux machine performs as a mail server, you would be remiss to not include AV scanning (lest your users be forwarding malicious mail).
  • cmus – A Small, Fast And Powerful Console Music Player For Linux
    You may ask a question yourself when you see this article. Is it possible to listen music in Linux terminal? Yes because nothing is impossible in Linux. We have covered many popular GUI-based media players in our previous articles but we didn’t cover any CLI based media players as of now, so today we are going to cover about cmus, is one of the famous console-based media players among others (For CLI, very few applications is available in Linux).
  • You Can Now Transform the Atom Hackable Text Editor into an IDE with Atom-IDE
    GitHub and Facebook recently launched a set of tools that promise to allow you to transform your Atom hackable text editor into a veritable IDE (Integrated Development Environment). They call the project Atom-IDE. With the release of Atom 1.21 Beta last week, GitHub introduced Language Server Protocol support to integrate its brand-new Atom-IDE project, which comes with built-in support for five popular language servers, including JavaScript, TypeScript, PHP, Java, C#, and Flow. But many others will come with future Atom updates.
  • This open-source Android app is designed to detect nearby credit card skimmers
    Protecting our data is a constant battle, especially as technology continues to advance. A recent trend that has popped up is the installation of credit card skimmers, especially at locations such as gas pumps. With a simple piece of hardware and 30 seconds to install it, a hacker can easily steal credit card numbers from a gas pump without anyone knowing. Now, an open-source app for Android is attempting to help users avoid these skimmers.
