IDG Contributor Network: Small mesh networks will soon help you find things

The famous adage, attributed to many different wits, goes along the lines of "insanity is repeating the same mistakes and expecting different results."Well, maybe that's a bit harsh, but I think you could argue that an indication of intelligence is not repeating the same unproductive act over and over again. And if that's the case, then why do we always misplace things?Surely, the clever thing to do would be to always put things, like car keys, in the same place each time. Like when arriving home, for example. But some of the smartest people I know don't do that.And before we get into a debate about whether those folks are indeed smart—as they look for their keys, I can happily announce that the whole argument is about to become moot.To read this article in full or to leave a comment, please click here

Guest Blog: REST API for Cumulus Linux ACLs

Cumulus Linux: REST API for Cumulus Linux ACLs

RESTful control of Cumulus Linux ACLs included a proof of concept script that demonstrated how to remotely control iptables entries in Cumulus Linux.  Cumulus Linux in turn converts the standard Linux iptables rules into the hardware ACLs implemented by merchant silicon switch ASICs to deliver line rate filtering.

Previous blog posts demonstrated how remote control of Cumulus Linux ACLs can be used for DDoS mitigationand Large “Elephant” flow marking.

A more advanced version of the script is now available on GitHub

The new script adds the following features:

  1. It now runs as a daemon.
  2. Exceptions generated by cl-acltool are caught and handled
  3. Rules are compiled asynchronously, reducing response time of REST calls
  4. Updates are batched, supporting hundreds of operations per second

The script doesn’t provide any security, which may be acceptable if access to the REST API is limited to the management port, but is generally unacceptable for production deployments.

Fortunately, Cumulus Linux is a open Linux distribution that allows additional software components to be installed. Rather than being forced to add authentication and encryption to the script, it is possible to install additional software and leverage the capabilities of a mature web server such as Apache.

Google sees success with balloon, airplane Internet

Google’s ambitious efforts to bring balloon and aircraft-borne connectivity to underserved areas of the globe are pushing past some key milestones and the company expects a public launch in a few years.Both projects have captured the imagination of many for their ability to beam Internet signals from platforms high up in the sky to areas without cellular networks, but represent significant engineering challenges for Google—just the kind of thing the company likes, said Sundar Pichai, a senior vice president at Google, speaking at Mobile World Congress in Barcelona.The oldest and perhaps best known of the two projects, Project Loon, seeks to use balloons flying around 20 kilometers (65,000 feet) above the Earth to deliver Internet signals. The company’s first experiments used a proprietary WiFi signal but that’s since changed to LTE cellular signals.To read this article in full or to leave a comment, please click here

SNL roasts Net Neutrality phonies

Net neutrality, even after last week's big FCC vote in favor of it, continues to be a term many don't quite get. SNL took advantage of that this past weekend to spoof tech pundits, and even works a Vint Cerf character into the mix.

Microsoft, Intel team on low-cost Windows 10 phones

Right now you can't buy Windows-based handsets that run on Intel chips, but that will change later this year with the mobile version of Windows 10. Microsoft's recent Windows Phone OSes worked only with ARM-based processors from Qualcomm. Though Windows 10 will also work on ARM systems, compatibility with Intel x86 chips breaks that exclusivity. The Windows 10 mobile OS will run on handsets and so-called phablets powered by Intel's upcoming Atom X3 chips, code-named Sofia, announced by the chip maker at the Mobile World Congress trade show. Devices with the X3 chips will be priced from under US$75 to $249. The X3 chips will also be offered in Android handsets.To read this article in full or to leave a comment, please click here

Intel rethinking tablets with new Atom X5, X7 chips

From Microsoft: Two new Lumia smartphones to upgrade later to Windows 10

BARCELONA -- Microsoft today announced two new Lumia smartphones running Windows Phone 8.1, which will be upgraded to the cross-platform Windows 10 later in the year. The company gave news media at Mobile World Congress a brief glimpse of how Windows 10 apps, such as an Excel spreadsheet, maps and Outlook email, look on a smartphone display. Windows 10 is currently in a publicly available preview version and will be ready for official release later in 2015. The new phones are the Lumia 640, with a 5-in. display, and the Lumia 640 XL with a 5.7-in. screen. The larger device ships in March and the smaller one in April, and both AT&T and T-Mobile will offer them.

Google confirms carrier plans, details coming soon

Google has confirmed for the first time that it plans to offer connectivity directly to mobile users in the U.S., but a senior executive downplayed the competition it would be to major U.S. cellular carriers.Several reports have said the company is preparing a service that would be offered across an existing cellular network under a Google brand—a so-called “mobile virtual network operator” or MVNO.
