The first article in this series introduced hashes, encryption/decryption, digital signatures, and digital certificates through the OpenSSL libraries and command-line utilities. This second article drills down into the details. Let’s begin with hashes, which are ubiquitous in computing, and consider what makes a hash function cryptographic.

On Friday, Mozilla issued a security advisory for Firefox, the default web browser in Fedora. This advisory concerns a CVE for a vulnerability based on type confusion that can happen when JavaScript objects are being manipulated. It can be used to crash your browser. There are apparently already attacks in the wild that exploit the […]

Same digit could be extended at Google as browser chaps 'evaluate the situation'. Amid Google's huffing and puffing over ad blockers, an update to Chromium-based browser Vivaldi puts privacy squarely in its sights.…

Lucid Vision Labs unveiled a MIPI-CSI2 equipped “Helios Embedded” version of its new Helios Time of Flight 3D camera that combines a Jetson TX2 with a Sony DepthSense IMX556PLR ToF sensor with under-5mm accuracy at 0.3 to 1.5 meters. Time-of-Flight (ToF) technology spans a range of infrared laser scanners from 3D imaging and navigation systems […]

Here at Codethink, we’ve recently focused our energy into enhancing the onboarding process we use for all new starters at the company. As we grow steadily in size, it’s important that we have a well-defined approach to both welcoming new employees into the company, and introducing them to the organization’s culture. read more

Ansible is one of the most popular automation engines in the world. It lets you automate virtually anything, from setup of a local system to huge groups of platforms and apps. It’s cross platform, so you can use it with all sorts of operating systems. Read on for more information on how to get the […]

Think we're at RISC of overdoing the Intel puns Ubuntu is set to drop support for the i386 processor architecture beginning with its next release.…

This article is the first of two on cryptography basics using OpenSSL, a production-grade library and toolkit popular on Linux and other systems. (To install the most recent version of OpenSSL, see here.) OpenSSL utilities are available at the command line, and programs can call functions from the OpenSSL libraries. The sample program for this article is in C, the source language for the OpenSSL libraries. read more

In this article, we will learn how to install Jenkins and configure it with Github for sending files to the server using SSH.

I've written about a number of chemistry packages in the past and all of the computational chemistry that you can do in a Linux environment. But, what is fundamental to chemistry? Why, the elements, of course. So in this article, I focus on how you can learn more about the elements that make up everything around you with Kalzium. KDE's Kalzium is kind of like a periodic table on steroids. Not only does it have information on each of the elements, it also has extra functionality to do other types of calculations.

Pimoroni’s $57 “Enviro+” pHAT for the Raspberry Pi can detect indoor air quality, temperature, pressure, humidity, light, and noise. You can hook up an optional “PMS5003 Particulate Matter Sensor” for detecting outdoor pollution. In 2016, Pimoroni launched a $20 Enviro pHAT board for the Raspberry Pi. The name was a bit misleading, however, since its […]

Like many other leaders in the open source software world, Naomi Ceder, board chair of the Python Software Foundation (PSF), took a non-traditional path into the Python world. As the title of her 2017 keynote at PyCon España explains, she came for the language and stayed for the community.

Aaeon’s rugged “Boxer-8150AI” computer runs Linux on a Jetson TX2 module and features 2x HDMI ports and 8x USB 3.0 ports for hooking up cameras for on-site edge AI analytics. Like the quad-GbE Boxer-8120AI, the Boxer-8150AI uses an Nvidia Jetson TX2 module and its CUDA-enabled AI libraries to analyze visual information from connected cameras. In […]

Video: The new list of the world's fastest computers is out and, once more, every last one runs Linux.

Radxa unveiled a 38 x 38mm, $10 and up “Rock Pi S” SBC that runs Linux on a quad -A53 RK3308. There’s also a v1.4 update of the RK3399-based Rock Pi 4 that adds 4MB SPI for booting NVMe drives plus a Rock Pi PoE HAT and a USB 3.0 eMMC adapter. Radxa, which returned […]

What next? Tugging the Test Plans? Grappling with GitLab? Microsoft-owned GitHub has waved a big bunch of bamboo shoots at code collaboration outfit Pull Panda.…

One of the jobs of the Linux kernel—and all operating system kernels—is to manage the resources available to the system. When those resources get used up, what should it do? If the resource is RAM, there's not much choice. It's not feasible to take over the behavior of any piece of user software, understand what that software does, and make it more memory-efficient. Instead, the kernel has very little choice but to try to identify the software that is most responsible for using up the system's RAM and kill that process.

Video: Docker has realized that Microsoft's new Windows Subsystem for Linux 2 has made Windows much more attractive both to Docker and its container developers for both Windows and Linux platforms.
