DevOps is a set of practices that automates the processes between software development and IT teams so they can build, test, and release software more quickly and reliably. The concept of DevOps is founded on building a culture of collaboration between IT and business teams, which have historically functioned in relative siloes. The promised benefits include increased trust, faster software releases, and the ability to solve critical issues quickly. read more

Last year, Google's Project Zero team discovered serious security flaws caused by "speculative execution," a technique used by most modern processors (CPUs) to optimize performance.

No bearded desktops with pointy hats to be seen here. The Linux Mint project turned out to be an early Christmas present, as it usually does, but this release is perhaps more important than usual given that Mint is much more alone in the Linux distro world than it was just one year ago.

Torvalds and company are not happy with Intel as they continue to move forward with delivering Linux security patches. Linux can deal with Meltdown and Spectre, the fundamental chip security problems, but that doesn't mean Linux's developers are happy about it.

Fortunately, Linux fans, you can change your console fonts. As always, the ever-changing Linux landscape makes this less than straightforward, and font management on Linux is non-existent, so we'll muddle along as best we can. In this article, I'll show what I've found to be the easiest approach.

In this tutorial, we will learn how to install and configure Concrete5 on Debian 9 server. Concrete5 is a free and open source Content Management System written in PHP language that can be used for publishing content on the Internet.

An industry-wide issue was found with the manner in which many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. All three rely upon the fact that modern high performance microprocessors implement both speculative execution, and utilize VIPT (Virtually Indexed, Physically Tagged) level 1 data caches that may become allocated with data in the kernel virtual address space during such speculation.

We have discovered that CPU data cache timing can be abused to efficiently leak information out of mis-speculated execution, leading to (at worst) arbitrary virtual memory read vulnerabilities across local security boundaries in various contexts. Variants of this issue are known to affect many modern processors, including certain processors by Intel, AMD and ARM.

Conventional wisdom suggests that leadership is strong, bold, decisive. In my experience, leadership does feel like that some days. Some days leadership feels more vulnerable. Doubts creep in: Am I making good decisions? Am I the right person for this job? Am I focusing on the most important things? read more

Why are you doing this? Munich City officials could waste €100m reversing a 15-year process that replaced proprietary software with open source following an official vote last year.…

I attended film school, and later I taught at a film school, and even later I worked at a major film studio. There was a common thread through all these different angles of the creative industry: creators need content. Interestingly, one movement kept providing the solution, and that was free culture, or, as it has been formalized, Creative Commons. read more

A serious security memory problem in all Intel chips has led to Linux's developers resetting how to deal with memory. The result will be a more secure, but -- as Linux creator Linus Torvalds says -- slower operating system.

You may have heard about Meltdown, an exploit that can be used against modern processors (CPUs) to maliciously gain access to sensitive data in memory. This vulnerability is serious, and can expose your secret data such as passwords. Here’s how to... Continue Reading →

To find the best articles, we looked at the following four categories: most-read overall, most popular on our social channels, most popular event-related articles, and most-read tutorials. The top 20 list includes several distro roundups from Jack Wallen and Swapnil Bhartiya, video interviews with Linus Torvalds, and some introductions to useful Linux commands.

Linux Journal was a print magazine for 17+ years, then a digital one for the next 7+. What shall we be now? That's the Big Question, and there are many answers, some of which are already settled.

It has been a full year here at the Fedora Magazine, and now it is over, we are looking back at some of the awesome content from our contributors. Here are some of the best articles from our contributors that... Continue Reading →

In this tutorial, we will show you how to install and configure the Varnish HTTP accelerator as a reverse proxy for an Apache web server. Varnish is a proxy server focused on HTTP caching. It's designed as an HTTP accelerator and can act as a reverse proxy for your web server.

Those who are new to the idea of open organizations (and open source in general) may have a difficult time envisioning how the open organization principles are incorporated as part of an existing culture. Many of these folks may not be participating in—or even have had extensive exposure to—an open organization, and therefore may not have ready access to a live community from which to observe and from which to learn. read more

Software Freedom Law Center claims Software Freedom Conservancy committed fraud A few days before the Christmas holiday, the Software Freedom Law Center (SFLC) made a peace offering of sorts in an ostensible effort to resolve its trademark dispute with the Software Freedom Conservancy (SFC).…

Linux pioneer Gaël Duval is working on an easy-to-use, Google-free, pro-privacy Android clone for your smartphone.
