Several years ago, I made the decision to replace proprietary technologies (mainly Apple products) with technology that ran on free and open source software (FOSS). I can't say it was easy, but I now happily use FOSS for pretty much everything. The hardest part involved my mobile handset. There are basically only two choices today for phones and tablets: Apple's iOS or Google's Android. Since Android is open source, it seemed the obvious choice, but I was frustrated by both the lack of open source applications on Android and the pervasiveness of Google on those devices. read more

Monitoring tools are used to continuously keep track of the status of the system and send out alerts and notifications if anything goes wrong. Zabbix is a free, open source and the ultimate enterprise-level monitoring tool designed for real-time monitoring of millions of metrics collected from tens of thousands of servers, virtual machines and network devices.

As a long-time member of the documentation team at Scribus, I keep up-to-date with the latest updates of the source so I can help make updates and additions to the documentation. When I recently did a "checkout" using Subversion on a computer I had just upgraded to Fedora 27, I was amazed at how long it took to download the documentation, which consists of HTML pages and associated images. read more

But Linux overlord braces for more Meltdown/Spectre excitement as kernelistas clean up remaining CPU messes ‘This was not a pleasant release cycle’ says Linux overlord, who prefers things boring, ‘Because boring really is good’…

The schedule is now live for Embedded Linux Conference + OpenIoT Summit North America 2018.

Linus Torvalds released the next version of the Linux kernel and, while are things are better with the chip security problems Meltdown and Spectre, more work needs to be done.

Chocolate Factory gives more ways to blast banners. Google says it will allow netizens to block nuisance "reminder" adverts that follow them around across websites.…

Today is Data Privacy Day, ("Data Protection Day" in Europe), and you might think that those of us in the open source world should think that all data should be free, as information supposedly wants to be, but life's not that simple. That's for two main reasons: read more

In a previous article, I wrote about how to prepare for a vacation so you aren't disturbed by a work emergency. As part of that article, I described how to prepare your computer:

Lime Microsystems has launched a Raspberry Pi compatible “Grove Starter Kit” option for its LimeSDR Mini radio hacker board with a GrovePi+ board, 15 Grove sensor and actuator modules, dual antennas for 433/868/915MHz bands, a base plate, and cables.

Security is always changing and failure always exists. This toxic scenario requires a fresh perspective on how we think about operational security. We must understand that we are often the primary cause of our own security flaws. The industry typically looks at cybersecurity and failure in isolation or as separate matters. We believe that our lack of insight and operational intelligence into our own security control failures is one of the most common causes of security incidents and, subsequently, data breaches.

Are you using Linux or Mac OS? If you think your system is not prone to viruses, then you should read this. Wide-range of cybercriminals are now using a new piece of 'undetectable' spying malware that targets Windows, macOS, Solaris and Linux systems.

Though open source is thoroughly mainstream, new software technologies and old technologies that get newly popularized sometimes inspire hand-wringing about open source licenses. Most often the concern is about the GNU General Public License (GPL), and specifically the scope of its copyleft requirement, which is often described (somewhat misleadingly) as the GPL’s derivative work issue.

This week in open source/Linux news, The Linux Foundation announced a restructuring of their networking projects under one umbrella, Slack launches on Linux, and more!
