Open source SDR SBC runs Snappy Ubuntu on Cyclone V
The open source, $299 “LimeSDR” board runs Snappy Ubuntu Core on a Cyclone V, and supports user-defined radios ranging from ZigBee to LTE.
UK-based Lime Microsystems, which develops field programmable RF (FPRF) transceivers for wireless broadband systems, has launched an open source software defined radio (SDR) board on CrowdSupply. Like other Linux-based SDR systems we’ve seen, the LimeSDR uses an FPGA to help orchestrate wireless communications that can be tuned, manipulated, and reconfigured to different wireless standards via software.
Critical Infrastructure Goes Open Source
The electrical grid, water, roads and bridges—the infrastructure we take for granted—is seldom noticed until it's unavailable. The burgeoning open source software movement is taking steps to help rebuild crumbling U.S. civil infrastructure while capitalizing on expansion in emerging markets by providing software building blocks to help develop interoperable and secure transportation, electric power, oil and gas as well as the healthcare infrastructure.
Under a program launched in April called the Civil Infrastructure Platform, the Linux Foundation said the initiative would provide "an open source base layer of industrial grade software to enable the use and implementation of software building blocks for civil infrastructure."
Where have all the MacBooks gone at Linux conferences?
In past years, the vast ocean of Apple logos really undercut any statement of “Linux is great.” People would, inevitably, retort with, “Then why are all the 'Linux People' using Macs?” Admittedly, that was a great point and has been a source of shame for many of us for a very long time.
But now things are different. The Apple logos are (mostly) gone from Linux conferences. This may be an unscientific observation from one person attending a few conferences in North America. Regardless, it's a great feeling.
UBUNTU 16.04 or Xenial Xerus, the latest upgrade of the popular Linux distribution, became available as a free download last month, and early reviews have been favorable. Instead of upgrading my existing Ubuntu 15.10 system, this time I opted for a fresh install. I also decided to give the improved Unity 7 desktop a go, instead of installing my preferred alternative XFCE.
The installation process was trouble-free, but because I started from scratch, I had quite a bit to add and tweak after the OS itself was installed.

Ubuntu developers are gathering this week for the Ubuntu Online Summit (UOS), which runs from May 3-5, to discuss development plans for the upcoming Ubuntu 16.10 Linux distribution release, code-named "Yakkety Yak."
With Ubuntu's install images continuing to be oversized with pushing 1.4GB on recent releases, Ubuntu developer Steve Langasek has raised the new limit for Ubuntu desktop images to 2GB. Other Ubuntu flavors are also following in this move.
Langasek has raised the size limit for images now to 2GB for being able to accomodate the current oversized images plus still having room to grow.
Canonical has been talking up Snaps, a new type of package format featured in Ubuntu 16.04 LTS. “Users can install a snap without having to worry whether it will have an impact on their other apps or their system,” reads Canonical’s announcement. But this isn’t true, as prominent free software developer Matthew Garrett recently pointed out.
