Univention GmbH was pleased to announce on February 16, 2016, the general availability of the first point release of their stable Univention Corporate Server (UCS) 4.1 server-oriented GNU/Linux operating system based on Debian.
The Open Knowledge Lab in Stuttgart, Germany has begun to develop their own IoT sensors that measure air quality every minute and report the data to a central server. It is then possible to display the smog levels on a map. See the map we're using.
The casings are actually some standard plumbing tubes. The other two main components are a Node MCU ESP8266 microcontroller that has built-in Wi-Fi and the actual analyzer. In the current revision this is an SDS 011 analyzer. A DHT22 sensor provides readings of the current temperature and humidity. All parts cost together around €30.
As you already know, Linux kernel is secure by default. But, it doesn’t mean that the softwares on the Linux system are completely secure. Say for example, there is a possibility that any add-ons on your web browser may cause some serious security issues. While doing financial transactions over internet, some key logger may be active in browser which you are not aware of. Even though, we can’t completely give the bullet-proof security to our Linux box, we still can add an extra pinch of security using an application called Firejail. It is a security utility which can sandbox any such application and let it to run in a controlled environment. To put this simply, Firejail is a SUID (Set owner User ID up on execution) program that reduces the risk of security breaches by restricting the running environment of untrusted applications.
I’m tired of having the same conversation over and over again with people so I figured I would put it into a blog post.
Many people ask me if I have tried or what I think of Solaris Zones / BSD Jails. The answer is simply: I have tried them and I definitely like them. The conversation then heads towards them telling me how Zones and Jails are far superior to containers and that I should basically just give up with Linux containers and use VMs.
Which to be honest is a bit forward to someone who has spent a large portion of her career working with containers and trying to make containers more secure. Here is what I tell them:
The Hadoop community has so far failed to account for the poor performance and high complexity of Hadoop, Johnson says. “The Hadoop ecosystem is still basically in the hands of a small number of experts,” he says. “If you have that power and you’ve learned know how to use these tools and you’re programmer, then this thing is super powerful. But there aren’t a lot of those people. I’ve read all these things how we need another million data scientists in the world, which I think means our tools aren’t very good.”
Today we want to announce some important changes regarding the Wine Staging packages provided at repos.wine-staging.com and dl.winehq.org. We completely reworked our build system to make the packages available sooner after a release and also added some new features, like downloading old packages for Debian / Ubuntu. The complete list of changes can be found in the announcement email on the Wine mailing list.
Have you ever played Fez on Linux ? Transistor ? Speed Runners ? Shenzen I/O ? Bastion ? or more recently, Owlboy ? Well if you have, you have benefited from the work of Flibitijibibo who is directly responsible for the port of such titles to your platform.
Open source is mission critical for Europe’s air traffic
It is entirely possible to use open source in a highly regulated environment such as air traffic control, says Dr Gerolf Ziegenhain, Head of Linux Competence & Service Centre (LCSC) in Mainz (Germany). Open source service providers can shield an organisation from the wide variety of development processes in the open source community.
So, you've got a fine head-mounted display and want to explore the delights of virtual reality. Right now, on Linux, that means getting the window system to cooperate because the window system is the DRM master and holds sole access to all display resources. So, you plug in your device, play with RandR to get it displaying bits from the window system and then carefully configure your VR application to use the whole monitor area and hope that the desktop will actually grant you the boon of page flipping so that you will get reasonable performance and maybe not even experience tearing. Results so far have been mixed, and depend on a lot of pieces working in ways that aren't exactly how they were designed to work.
At this year’s GUADEC in Manchester we have rooms available for you right at the venue in lovely modern student townhouses. As I write this there are still some available to book along with your registration. In a couple of days we have to a final numbers to the University for how many rooms we want, so it would help us out if all the folk who want a room there could register and book one now if you haven’t already done so! We’ll have some available for later booking but we have to pay up front for them now so we can’t reserve too many.
A Kickstarter campaign for the Niryo One, an open source 3D printed 6-axis robotic arm, has more than doubled its €20,000 target after just a couple of days. The 3D printed robot is powered by Arduino, Raspberry Pi, and Robot Operating System.
Jupiter Broadcasting’s long-running podcast, Linux Action Show, will soon be signing off the air…er, fiber cable, for the last time. The show first streamed on June 10, 2006 and was hosted by “Linux Tycoon” Bryan Lunduke and Jupiter Broadcasting founder Chris Fisher. Lunduke left the show in 2012, replaced by Matt Hartley, who served as co-host for about three years. The show is currently hosted by Fisher and Noah Chelliah, president of Altispeed, an open source technology company located in Grand Forks, North Dakota.
