A new set of vulnerabilities were disclosed recently. As part of mitigating “meltdown”, the kernel introduced a new feature called Kernel Page Table Isolation (KPTI). This was a big change to come in late in the typical kernel development cycle... Continue Reading →

Contrary to some beliefs, Linux distros are rarely just carbon copies of other distros. As is evident in this look at five of the most popular Linux server distributions, each is different, with distinct strengths and weaknesses.

Enterprise Java has been defined by two players: Spring on one side and Java Enterprise Edition on the other. The Java EE set of specifications was developed in the Java Community Process under the stewardship of Oracle. The current Java EE 8 was released in September 2017; the prior version came out in 2013. read more

Meltdown and Spectre are two vulnerabilities that impact almost all computers, tablets and smartphones on the earth. Does it mean you can be hacked? What can you do about it?

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

Valve have updated the SteamOS beta once again, this time they're pulling in some major package updates to give a better experience.

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.

Opera Software released today the Opera 50 web browser for GNU/Linux, macOS, and Windows systems, a major release that comes with innovative new features and dozens of improvements.

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.

Few new technologies have raised as much discussion as blockchain. One reason is the controversy, concern, and perceived opportunity around blockchain-based cryptocurrencies such as bitcoin and ether. Another is the growing crop of ventures crowdfunded via initial coin offerings (ICOs).

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.

Red Hat suggests customers update their systems to protect against the Intel Meltdown processor flaw. Discovered some time ago, but only just yesterday brought into public view, the CPU flaw allows an attacker to bypass restrictions to gain access to privileged memory (which should be inaccessible) -- possibly stealing sensitive information from computer systems, mobile devices, and cloud deployments.

One of the most common problems that occurs with WordPress is 500 Internal Server Error. In this guide we will show you few tips on how to fix 500 Internal Server Error and get your WordPress site up and running on your Linux VPS.

After Red Hat and SUSE, now it's Canonical's turn to respond to the Meltdown and Spectre hardware bugs that affect billions of hardware device.

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.

Linux kernel maintainers Greg Kroah-Hartman and Ben Hutchings have released new versions of the Linux 4.14, 4.9, 4.4, 3.16, 3.18, and 3.12 LTS (Long Term Support) kernel series that apparently patch one of the two critical security flaws affecting most modern processors.

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
