Tizen SDK Updated for the Gear S

Filed under
Linux

By now, you've probably seen the news about the Tizen-based Gear S smartwatch that was unveiled at IFA. Aside from having a massive curved screen (for a watch, at least), it also has GSM connectivity, meaning it can truly function as a standalone device.

If you're an app developer and that didn't get you excited, you should probably get someone to check your pulse (or I suppose you can have the Gear do it for you). We've talked in the tech industry about convergence devices for years, and this is exactly the sort of device we mean. And yes, various things have been getting cellular connectivity for years, but aside from phones, it's really only a recent trend that companies are legitimately working to build third party app ecosystems around these devices.

How Red Hat and the open-source community are fortifying Docker

As Docker has exploded in popularity, so too has the open-source community around it. Now, as more and more large enterprise software companies jump on the Docker bandwagon, the community is tackling some of the larger issues behind the emerging technology, namely container security.

One of the big names driving security improvements in Docker container technology and the Linux kernel is Red Hat. Daniel Walsh, a Red Hat security engineer who’s spent the better part of 13 years working on the Security-Enhanced Linux module, is among those spearheading Red Hat’s effort to bolster container security with the features in Red Hat Enterprise Linux 7 and other open-source initiatives.

Drawing Web content with OpenGL (ES 3.0) instanced rendering

Filed under
Graphics/Benchmarks
GNOME

There is one important conclusion coming out from these experiments: The fact that a rasterizer is normally stateless makes it very inefficient to modify a single element in a scene.

By stateless I mean they do not keep semantic information about the elements being drawn. For example, lets say in one frame I draw a rectangle, and for the next frame I want to draw the same rectangle somewhere else on the canvas. You already have a batch with all the elements of the scene, happily stored in a vertex buffer object on GPU memory, and the rectangle in question is there somewhere. If you could keep the offset where that rectangle is in the batch, you could modify its attributes without having to drop and re-submit the whole batch.

How the Terminal makes Ubuntu Touch worth using

Filed under
Ubuntu

Sometimes it's the little things that make all the difference. Even something that seems completely inconsequential can take a project from “meh” to “awesome” with astonishing speed.

Take Ubuntu Touch, for example.

There is much about that system that I love. It's mostly Open Source (with very few exceptions) and allows me to have a Debian-based Linux distro right in the palm of my hands. Being able to “sudo apt-get install” on the go is just so incredibly handy. Damn near brings a tear to my eye.

Tizen Samsung Gear S to launch with some impressive Apps

Filed under
Linux
Gadgets

The Smartwatch market is certainly going to be a lucrative space for the companies that can be first to release their products, go through the lessons learnt cycle, and also be able to build a viable application ecosystem on top of it, which shouldn’t be confused with standard smartphone apps, as not all apps translate well to your wrist, and therefore you don’t need as many. No one is going to want to edit a picture on their wrist on the move, even if they can !!!

Xen & Docker: Made for Each Other

Filed under
Linux

Containers and hypervisors are often seen as competing technologies – enemies even. But in reality the two technologies are complementary and increasingly used together by developers and admins. This recent Linux.com article talked about this supposed battle, noting however that developers are using Docker in traditional VMs to bolster security. Containers allow users to develop and deploy a variety of applications with incredible efficiency, while virtualization eliminates any constraints and/or exposure to outside attacks.

Uniting these technologies helps developers and system administrators be even more efficient. Let’s take a closer look at how to achieve this with Docker and Xen Project virtualization, and why we expect more and more organizations to use them together in the near future. This will also be a key topic at the September 15 Xen Project User Summit at the Lighthouse Executive Conference Center in New York City. Register today to learn more about enabling Docker in Xen environments for a truly open infrastructure.

FSF and Debian join forces to help free software users find the hardware they need

Filed under
GNU
Linux
Debian

The Free Software Foundation (FSF) and the Debian project today
announced cooperation to expand and enhance h-node [1], a database to
help users learn and share information about computers that work with
free software operating systems.

1: http://h-node.org

While other databases list hardware that is technically compatible with
GNU/Linux, h-node lists hardware as compatible only if it does not
require any proprietary software or firmware. Information about hardware
that flunks this test is also included, so users know what to avoid. The
database lists individual components, like wifi and video cards, as well
as complete notebook systems.

Why Did Docker Catch on Quickly and Why is it so Interesting?

Filed under
Linux

One reason Docker is interesting is that all four answers are each individually useful, but can be used in combination. This causes cross-pollination of ideas and patterns. For example, someone might start using Docker because they like the speed and portability, but find that they end up adopting the configuration and Docker hub patterns as well.

The Docker technology is still fairly new; work is underway to add missing features, and a large ecosystem of related projects and companies is forming around it. There’s a lot of interest in the technology from the VC community, as we try to figure out whom to fund to do what, and how the story will play out in the longer term.

Linus Torvalds Says Linux Binary Packages Are Terrible, Valve Might Save the Desktop

Filed under
Linux

One of the main problems with Linux platform fragmentation is that there are a number of concurrent binaries available for various platforms and they are not compatible with each other. Linus Torvalds explains why he thinks that the binary concept on Linux is broken and why he doesn't use them for his projects..

Students build smart devices and scientific instruments with Arduino

Filed under
OSS

Arduino is an open source microcontroller for prototyping electronic devices. It can be connected to a wide array of inexpensive sensors to collect data. These data can be saved to an SD card, passed back to a PC, or uploaded to the cloud for further processing. An Arduino can actuate motors, creating scientific instruments that move as well as sense. As Massimo Banzi, co-inventor of Arduino, showed in his TED talk, middle and high school students can capably create scientific instruments with Arduino. He gives examples of students who have created earthquake sensors, pH meters, and a wide variety of robots.

Where do we stand at 45 days before FUDCon Managua 2014

Filed under
Red Hat

Sponsors:
It is well known that our bigger sponsor the Fedora Project itself. Beside that is the University de Ciencias Comerciales, providing the venue. Blue Hosting has come forward to provide some funds. Yoytec form Panama will be helping a bit. As said before Guegue Comunicaciones is covering the cost of T-shirts. The Mansion Teodolinda hotel has come with a good deal.

We are talking with Movistar, cell phone company and ISP. They provide service to the University, so it is our interest to see if they can provide some extra bandwidth and some other sponsorship. There is also the ongoing talk with Fudacion Zamora Teran, they are in charge of OLPC in Nicaragua. They expressed interest in helping the event but still they are looking how that help will be materialize.

It's time to split Linux distros in two

Filed under
Linux

You can take a Linux installation of nearly any distribution and turn it into a server, then back into a workstation by installing and uninstalling various packages. The OS core remains the same, and the stability and performance will be roughly the same, assuming you tune they system along the way. Those two workloads are very different, however, and as computing power continues to increase, the workloads are diverging even more.

Maybe it's time Linux is split in two. I suggested this possibility last week when discussing systemd (or that FreeBSD could see higher server adoption), but it's more than systemd coming into play here. It's from the bootloader all the way up. The more we see Linux distributions trying to offer chimera-like operating systems that can be a server or a desktop at a whim, the more we tend to see the dilution of both. You can run stock Debian Jessie on your laptop or on a 64-way server. Does it not make sense to concentrate all efforts on one or the other?

Interviews

After watching classic TV shows such as Knight Rider and Street Hawk in his youth, IT professional and Raspberry Pi enthusiast Derek Knaggs was inspired to create a low-cost in-car computer using a Raspberry Pi.
The Pi sits in the centre console of his Ford Focus, wired to the display of an Xtrons DVD player (optional) as well as two TFT screens in the rear headrests. Control is via a Xenta wireless keyboard with mouse touchpad, while a smartphone can be used as a wireless hotspot to give the Pi an internet connection on the move.
Having recently added a reverse camera to his already top-notch project, we caught up with Derek to learn more about it…
