The US Ranks 55th in Terms of LTE Download Speeds

The quality of a country’s mobile network is often decided by a recipe that’s two parts economic, and one part geography. While small, developed nations like South Korea and Hong Kong can easily provide complete coverage and fast speeds to their dense populations, larger, poorer countries often struggle to deliver full bars to all of their territory.

Countries that are big and rich, like America, tend to get networks that are somewhere in the middle — good on coverage, for example, but not so great on speed, as a report into LTE in the US by OpenSignal showed earlier this week. Now, the network-testing company has released its worldwide report for Q4 2015, allowing us to see how America stacks up with the rest of the globe.

​How to Install Linux Mint on Your Windows PC

yumi-usb-stick-burnerAre you a Windows power-user? You can get and install Linux Mint running on your PC — either to try it out, or as a replacement for Windows.

Getting Started With OpenStack [Webinar]

OpenStack Webinar Feb. 25, 2016The conversation around the adoption of OpenStack, the open source cloud technology platform, continues to gain momentum. Analysts at Forrester recently declared it “enterprise-ready” while many enterprise companies have taken the leap and deployed it. One thing that seems to be a dominant theme is that there are not enough professionals with OpenStack skills to keep up with demand.

A recent SUSE report recently cited that 86 percent of senior IT professionals looking to move business-critical workloads to the private cloud say that a lack of available skillset is making their company reluctant to pursue it. In an effort to mitigate this OpenStack talent shortage and increase access to learning, The Linux Foundation recently launched an online self-paced course covering OpenStack Administration Fundamentals.

If you’re not ready to dive into training just yet or if you’re still deciding whether OpenStack is the right choice for your organization, join us for a free webinar with our guest Tim Serewicz, who teaches OpenStack and Linux performance and tuning courses for The Linux Foundation Training. He will address the most common OpenStack questions and concerns:

  • I think I need OpenStack but where do I even start?

  • What are the problems that OpenStack solves?

  • History & Growth of OpenStack: Where has it been and where is it going?

  • What are the hurdles?

  • What are the sore points?

  • Why is it worth the effort? 

Register today to save your spot in this engaging and interactive webinar on Thursday, February 25 at 11:00 a.m. Pacific. Can’t make it? Registering will also ensure you get a copy of the recording via email after the presentation is over.

Clever New GitHub Tool Lets Coders Build Software Like Bridges

Jesse Toth says that upgrading an Internet service is like building a new bridge across San Francisco Bay. In building the new eastern span of the Bay Bridge, engineers didn’t tear down the old one and erect the new one in its place. They built the new span alongside the old one, before making sure the new bridge could handle the same traffic. …

Toth is an engineer at GitHub—the company at the heart of the modern software world—and today, she and her fellow GitHub engineers officially released a tool designed to ensure that your new code is ready before you disconnect your old code…
