In most cases, when a machine crashes or fails, we lose whatever we had loaded into memory, which for some applications can result in quite a bit of time and effort to recover when the system comes back online. At LinuxCon Europe, Maciej Maciejewski, Senior Software Engineer at Intel, talked about how persistent memory can be used to retain its contents after a power failure.

If you happen to administer one or more OpenLDAP servers, you know that they can be a challenge to work with. Working with LDAP itself can be a bit tricky; to that end, many opt to go the phpLDAPadmin route (which is an amazing tool for individual servers). There’s one particular piece of software that does an outstanding job of managing multiple LDAP servers: Apache Directory Studio.

Suppose you are a system administrator in a company where teams mostly work on Linux with limited privileges. Now imagine a situation where members of one of the teams - as part of some new work - need to frequently edit a file that requires superuser privileges. What would you do?

In this week's top 5, I highlight an intro to the Linux boot, a primer on the ESP8266 board, Linux command-line tools for data analysis, a Python script to find corrupted images, and open source applications for a Windows machine.

VIA unveiled an SODIMM-style COM based on its Cortex-A9 WM8850 SoC, with 512MB RAM and 8GB eMMC, plus Ethernet, CSI, graphics, USB, and serial ports. The 68.6 x 43mm “SOM-6X50” computer-on-module appears to be VIA’s second-ever ARM COM.

SSL security allows users to trust the authenticity of a site’s content. While you can host an SSL blog on both GitHub and GitLab pages, only GitLab supports SSL for custom domains. This article shows you how to use Pelican and Let’s Encrypt to produce... Continue Reading →

If you love technology, you can find a space for yourself and connect with others around mutual interests, according to Avni Khatri, president of Kids on Computers (KoC), a nonprofit that sets up computer labs using donated hardware and open source software in areas where kids have no other access to technology.  

What is the best language for a budding programmer to get their start with? There are probably as many opinions about which language is best for beginners as there are languages to choose from. And the options change all of the time. When we asked this question two years ago, Python came out on top as the clear winner. But is it still the best choice today? read more

When you mention open source hardware, people typically think about community-backed hacker boards. However, the open hardware movement is growing on many fronts, including medical devices, rocketry and satellites, 3D printers, cameras, VR gear, and even laptops and servers.

You don't have to be a data scientist to be fascinated by the world of machine learning, but a few travel guides might help you navigate the vast universe that also includes big data, artificial intelligence, and deep learning, along with a large dose of statistics and analytics. read more

Why, you ask, should anyone care about Vim? It's complex, it's so old it's a fossil, and you like Kate/Leafpad/Geany/Gedit/Nano/Jed/Lime/Emacs/what-have-you, and the Linux world is cram-full of great text editors, so why bother with Vim?

There are many compelling reasons to use Open Source Software (OSS), all of which add up to a competitive advantage for the organization.

Learn how to work from anywhere and keep your data, identity, and sanity. If your systems administrators are remote workers, you may wish to establish a set of guidelines to help ensure that their workstations pass core security requirements. This will help reduce the risk that they become attack vectors against the rest of your IT infrastructure.

Arch Linux is a Linux-based operating system that is designed for i689 and 86-64 computers. Arch Linux is also popular for having a comprehensive documentation in form of the community wiki known as ArchWiki. This Linux operating system is based on binary packages that are targeted for i832, 64-bit, and 32-bit systems and optimized for the best performance on the modern hardware systems.

At ELC Europe, Intel MinnowBoard SBC evangelist John Hawley surveyed open hardware trends, and their impact on OS-enabled device and system development. When you mention open source hardware, people typically think about community-backed hacker boards. However, the open hardware movement is growing on many fronts, including medical devices, rocketry and satellites, 3D printers, cameras, ..........

Would you believe in a safe peer-to-peer cloud storage solution? Storj Labs thinks you will with their blockchain-protected, open-source service.

So you've landed on some data you want to analyze. Where do you begin? Many people used to working in a graphical environment might default to using a spreadsheet tool, but there's another way that might prove to be faster and more efficient, with just a little more effort. And you don't need to become an expert in a statistical modeling language or a big data toolset to take advantage of these tools. read more

Open education is a hot topic in both the K-12 and higher education spaces due to a number of factors, including the desire to make education more affordable. read more

The field of statistics typically has had a bad reputation. It's seen as difficult, boring and even a bit useless. Many of my friends had to take statistics courses in graduate school, so that they could analyze and report on their research. To many of them, the classes were a form of nerdy, boring torture.

Innovations are much more interesting than inventions.  The “laser” is a classic invention and “FedEx” is a classic innovation.  Successful innovation disrupts entire industries and ecosystems as we’ve seen with Uber, AirBnB, and Amazon to name just a few.   The entire global telecommunication industry is at the dawn of a new era of innovation.  Innovations should be the rising tide in which everybody wins except what’s referred to as “laggards.”   Who are the laggards going to be in this new era of open communications?  You don’t want to be one.
