Linux Mint 17 continues in a line of Linux desktop-focused releases, and in testing we found it’s become more mature than prior versions. There’s something here to please everyone. Civilians won’t hurt themselves deploying Cinnamon over Linux Mint 17. Developers will enjoy any of the versions, and the hard core will find lots to love with the LMDE versions.
One of the problems with Ubuntu that seems to be mentioned quite a lot is the proper lack of support for mobile modems. This might not look like a big problem, but the mobile modems are being used on a much larger scale than 2 or 3 years ago and the rate of adoption for this kind of devices is not slowing down.
The mobile modems are now in great demand, especially for people who are using their Internet plan on the road. Mobile Internet is becoming a lot cheaper and companies have started selling modems to people who want to have online access on their laptop and still use their phone.
LLVM has also recently inspired a project named Vellvm, where the design of the program and its output are both formally verified. The compiler's input and production can then be independently proven as consistent to defend against introduced bugs. The CompCert compiler already does this, but only for C; a formally verified version of LLVM could in theory do this for any language.
Firefox Beta Gets Built-In WebRTC Video Calls On Desktop, Chromecast And Roku Video Casting On AndroidSubmitted by Rianne Schestowitz on Monday 8th of September 2014 10:05:29 PM Filed under
On Android, the main addition is Chromecast and Roku video casting support. When you play a video on a site like CNN that serves up (mobile) videos through an HTML5 player and doesn’t use Flash (and your Roku or Chromecast are up and running), you can now stream your mobile video right to your TV in the living room. For Chromecast users, that should work without any major setup. Roku users will have to install the Firefox channel on their device, though.
Mozilla notes that some sites customize their HTML5 video player so the “Send to” icon that would usually appear in the player to make this work won’t show. To get those working, you have to start playing the video and the “Send to Device” icon will then appear in the URL bar.
All of this, as usual, is still very much in beta and prone to bugs. But that’s what the beta channel is all about, after all, and if you find any issues, you can file your bugs here.
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.
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.
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.
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.
Qt 5.4 release process is ongoing and we now have the Qt 5.4 Alpha release available. As always, the Alpha is in source code only. Binary installers will be available in a few weeks with the Beta release. Features of Qt 5.4 are now frozen and in the next months the focus is in finalising and polishing functionality. To give an overview what is coming with Qt 5.4, I’ll summarise the highlights of the Qt 5.4 Alpha release.
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 !!!
Operating System U: A new Linux based OS with a firm focus on you the user and functionality over UI overhauls, hits KickStarterSubmitted by Rianne Schestowitz on Monday 8th of September 2014 08:32:09 PM Filed under
There's isn't probably a piece of software that is as hated as Windows 8's Metro UI. Some seasoned Windows enthusiasts like it, but most of the normal day-to-day user had a hard time getting used to it. Operating System U is being readied with the regular user in mind, and is based on Manjaro Linux. A quick overview of the project.
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.
The Free Software Foundation (FSF) and the Debian project today
announced cooperation to expand and enhance h-node , a database to
help users learn and share information about computers that work with
free software operating systems.
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.
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.
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..
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.
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.
