A new OpenSUSE Linux is coming to town, and it’s all about stability

Linux users come in many shapes and sizes, but those in the business world typically steer clear of the bleeding edge. That's why the OpenSUSE project recently switched to a two-pronged development approach, with one version focused on constant updates and another on enterprise-grade stability. On Wednesday, the latter took a big step forward.The first beta version of OpenSUSE Leap 42.2 is now available, giving enterprises and other stability-minded users the chance to check it out and get a taste of what's coming in the final release, which is due Nov. 16. This is the first key update to the Leap software since OpenSUSE adopted its dual-path approach late last year with OpenSUSE 42.1.To read this article in full or to leave a comment, please click here

An I2RS Overview

What is the Interface to the Routing System (I2RS), and why do we need it? To get a good I2RS overview, consider the following illustration for a moment—

rib-fib

What does the interface between, say, BGP and the routing table (RIB) actually look like? What sort of information is carried over this interface, and why? A short (and probably incomplete) list might be—

  • Routes being installed by the routing protocol into the RIB—this is the most obvious bit of information, allowing the device to actually build a forwarding table
  • Routes being overwritten—this isn’t as obvious as installed routes, but BGP (for instance), can only advertise what is installed in the local table; hence if a route it has installed is overwritten, the process needs to know to stop advertising the route
  • Routes being removed from the routing table—perhaps even less obvious, but some routing protocols (BGP is one) allow for multihop routes; when the next hop is removed, any routes using that next hop need to be removed as well
  • Connected interfaces removed—this is often handled as a route removal, but it impacts more than just multihop routes; removing a connected route implies loss of reachability to a specific set of Continue reading

Asus may be planning Microsoft HoloLens competitor in its VR push

Virtual reality headsets are considered the hot new PC devices, and Asus is planning to stake a claim of its own.  Asus on Wednesday said it intends to release VR headsets. VR headsets can be versatile 3D PCs that make 2D laptops and desktops look pale in comparison, Asus said at the IFA trade show in Berlin. "Asus has a few VR options coming up really soon. Once that happens, you will be free from devices and immersed in 360 degrees of pure entertainment that will blow you away," said Jen Chuang, Asus' design center director. Asus didn't provide further details, but the company seems to want to focus on untethered VR headsets, or perhaps even mixed-reality headsets like Microsoft's HoloLens. It could tap into a few technologies to do so.To read this article in full or to leave a comment, please click here

Instagram finally lets iOS users zoom in

File this under: What took you so long, Instagram?I can't tell you the number of times I've attempted to zoom in on one of my crummy Instagram photos, hoping I might see better detail than I usually capture in my faraway shots. Now Instagram has enabled pinching and zooming of not just photos, but videos, for those with iPhones and other iOS devices. And I checked: It works with existing photos and videos, not just ones created from here on."Starting today, you can pinch to zoom on photos and videos in feed, on profiles and on Explore. Dive into an adorable puppy’s smile or into every detail of your friend’s new shirt," Instagram proclaims.To read this article in full or to leave a comment, please click here

SAP builds next-gen data warehouse for the cloud

With an eye on the need for more scalable, real-time analytics, SAP today unveiled SAP BW/4HANA, its next-generation data warehouse product for the real-time digital enterprise.BW/4HANA will support on-premises deployments, but will also be available on Amazon Web Services (AWS) and SAP HANA Enterprise Cloud (HEC), says Neil McGovern, senior director, Product Marketing, SAP Data Warehousing."We're trying to give our customers some options," he says. "AWS is infrastructure as a service (IaaS) — you can provision very quickly and inexpensively. With HEC, it's far more of a complete, turnkey solution — more platform as a service (PaaS)." SAP’s next-generation data warehouse service, SAP BW/4HANA, provides interactivity with historical and live data whether that data lives inside or outside the enterprise.

HPE CIO tackles tough ‘spin merge’ with CSC

It’s become fashionable to call CIOs chief integration officers because they integrate acquired assets, blend on-premises infrastructure and cloud technology, and collaborate with several stakeholders on digital services.

Facebook’s new algorithm will help save VR movies from shaky-cam

Facebook wants to make sure that any VR home movies shared on its social network won't make people puke. That's why the company is building a new video stabilization algorithm that will help smooth out all of the bumps and shakes that come from wielding a 360-degree camera. The new algorithm is designed for stabilizing 360-degree videos in particular, something that Facebook says is important for addressing the growing amount of spherical footage. Previous stabilization technology was designed primarily for videos with a smaller field of view because they were usually taken with traditional 2D cameras. It's an important step for Facebook, which has been focused on virtual reality content and 360-degree video, especially after its US$2 billion acquisition of VR hardware maker Oculus in 2014. The social network introduced support for 360-degree video a year ago and has been pushing it ever since. To read this article in full or to leave a comment, please click here

I have all the code—now I want to hug a free software developer

I have all the source code.That’s not some sort of metaphorical declaration of the glory of free and open source software; I’m not talking about simply having the rights to go download some source code. I mean it quite literally: I have the source code necessary to build all of the software powering my PC.Right now. Like, on my hard drive.+ Also on Network World: 30 days in a terminal +I did this simply because I could. Because the source code is there. Source code repositories galore. And as I sit here typing this, I have all of it—at least for everything I use every day. And I’ve backed it up.To read this article in full or to leave a comment, please click here

Worth Reading: The Internet of Poorly Working Things

Of course, not all connected devices are so easily mocked; some devices are dead serious: home security, HVAC, almost any kitchen appliance — even our very smart toaster. And it’s not that the IoT doesn’t work. The situation is actually worse than that: The IoT randomly works. Devices stop and restart, they require visit to unsupportive customer support pages and helpless Your Call Is Important To US help lines (and now we have chatbots). If you think I exaggerate, google “Nest trouble” or “smart bulbs trouble”. We don’t have to look around much to find the culprit: with its razor-thin margins, the Consumer Electronics (CE) culture offers a big fat target for our inquisition. —Monday Note

Defense Department needs to embrace open source or military will lose tech superiority

The Department of Defense needs to move past open source myths that have been debunked and jump on the open source bandwagon or the Department of Defense (DoD) and U.S. military will not be able to maintain tech superiority, warns a Center for a New American Security (CNAS) report.To maintain technological superiority, the DoD needs “to acquire, develop, deploy and maintain cutting-edge software” systems. “Unless the department is able to accelerate how it procures, builds and delivers software, it will be left behind,” said the authors of “Open Source Software and the Department of Defense” (pdf).To read this article in full or to leave a comment, please click here
