If you read the OpenStack User Survey Report you’ll find OpenStack, the open-source Infrastructure-as-a-Service (IaaS) cloud, is growing ever more popular. But at the same time OpenStack‘s branding is getting a little confusing. While the IaaS cloud name remains the same, its branding is pivoting to Open Infrastructure, or is it OpenDev?
OpenStack–uh Open Infrastructure? OpenDev?–remains popular More>

If you want to install a program on the Debian/Ubuntu/MintLinux distribution family, you almost always end up using the core software installer program Advanced Package Tool (apt). It works well, but security researcher Max Justicz recently found a nasty way to make a man-in-the-middle attack on apt.
Adding salt to this wound, Justicz found the hole would enable a remote attacker to execute arbitrary code as root on any system installing any package. To understand how it attacks, you need to understand how apt works.

I am so, so tired of reading stories proclaiming the mobile wonders of the world of tomorrow. 5G will bring up 8K videos to our self-driving cars, and it will do it 100 times faster than 4G! Give me a break.
I am not cynical. I am realistic. And the reality is that 5G will not be that fast. And at least for the next few years, it will be available in just a few cities, and only in a few square blocks of those. In other words, it would be foolish this year to pay extra for any of the handful of 5G phones that will be available. Same goes for 2020. And, for that matter, 2021.
Let me tell you why.

Canonical‘s Ubuntu is best known for its Linux desktop, but the company really makes it money from the cloud. And, founder Mark Shuttleworth has said, the Internet of Things (IoT). So, it comes as no surprise that Ubuntu Core is bringing Ubuntu 18.04 Long Term Support (LTS) codebase to embedded devices.

Twenty years ago, when it became apparent how important Linux would become, the U.S. National Security Agency created a mandatory access control (MAC) architecture for Linux. As in other realms, security is always important, but sometimes it’s especially important. From its creation and extending to today, Security-Enhanced Linux (SELinux) has blocked tampering threats and prevented attempts to bypass application security.
I hasten to stress that you should not adopt SELinux just because the extra-robust security functionality exists. Yes, I know how much security matters to your business, but SELinux isn’t for everyone. Running SELinux takes extra time, requires far more hands-on involvement than other Linux distributions, and demands deep knowledge about Linux architecture.

When I cut the cable cord in 2009, I saved over $100 a month and still got to watch all my shows. Ten years later, my internet video streaming bills are closing in on cable TV-level bills.
What happened?
What happened was internet streaming is copying over the tired, old cable models. Sure, the delivery technology is different, but to get the most from today’s net-based television shows, you need a streaming device. That’s changing, too, as full-featured streaming gets built into newer TVs with built-in Roku.
