In prior years, this annual series covered individual apps. This year, we are looking at all-in-one solutions in addition to strategies to help in 2021. Welcome to day 16 of 21 Days of Productivity in 2021. The Raspberry Pi is a pretty amazing little computer—small, surprisingly powerful, and very easy to set up and use. I have used them for home automation projects, dashboards, and a dedicated media player. But can it be a productivity powerhouse as well? The answer is, quite simply, yes. read more

Appareo’s IP67-rated, -40 to 75°C tolerant “Gateway 370” telematics gateway runs Linux on a Cortex-A9 SoC and supplies Iridium SBD, 433MHz (RFID), 4G LTE, WiFi/BT, and GPS plus LAN, BroadR-Reach, DIO, and CAN links. Fargo, ND based Appareo has launched a wireless telematics control unit (TCU) for heavy machinery in applications such as construction and […]

Some time ago, I wanted to give a blackboard-style look to a typeset equation. I started playing around with the GNU Image Manipulation Program (GIMP) and was satisfied with the result. The problem was that I had to perform several actions on the image, I wanted to use this style again, and I did not want to repeat the steps for all the images. Besides, I was sure that I would forget them in no time. read more

Monitoring your RDS instances is very important, and the same applies to other resources. In this article, we will create a simple alarm for an RDS MySQL instance which will check for free storage space on the instance.

The COVID-19 pandemic created many new challenges for businesses in 2020 as they rapidly moved non-essential workers to remote operations. However, it also created tremendous opportunities for innovation as people searched for effective ways to work and collaborate virtually. read more

'They're not closing a security hole, they're just requiring that everyone use Chrome' Fedora's maintainer for the open-source Chromium browser package is recommending users consider switching to Firefox following Google's decision to remove functionality and make it exclusive to its proprietary Chrome browser.…

The Unipi Gate G110 and G100 are PLC-ready DIN-rail gateways that run Linux on a quad -A53 SoC with 16GB eMMC, GbE and 10/100 LAN ports, and up to 2x RS485 ports with modular extensions. Czech based Unipi, which started out in 2014 with a Raspberry Pi based UniPi automation controller board and followed up […]

Neousys unveiled a fanless, 112 x 87 x 50mm “POC-40” computer with an up to 3.0GHz, dual-core Atom x6211E plus up to 32GB DDR4, 2x GbE, 4x USB, 3x M.2, and DP, 2x serial, and isolated DIO. Last month, Neousys announced one of the first Intel Elkhart Lake based embedded PCs with its ultra-compact (153 […]

One of the things I appreciate about Linux versus proprietary operating systems is that almost everything can be managed and configured from the command line. That means that nearly everything can be configured locally or even remotely via an SSH login connection. Sometimes it takes a bit of time spent on Internet searches, but if you can think of a task, it can probably be done from the command line. read more

An in depth howto for converting an existing filesystem to BTRFS on Fedora.

In 10 ways to analyze binary files on Linux, I explained how to use Linux's rich set of native tools to analyze binaries. But if you want to explore your binary further, you need a tool that is custom-made for binary analysis. If you are new to binary analysis and have mostly worked with scripting languages, 9 essential GNU binutils tools will help you get started learning the compilation process and what constitutes a binary. read more

For a long time, the ifconfig command was the default method for configuring a network interface. It served Linux users well, but networking is complex, and the commands to configure it must be robust. The ip command is the new default networking command for modern systems, and in this article, I'll show you how to use it. read more

Avalue’s fanless, rugged “EMS-TGL” embedded PC runs Linux or Win 10 on embedded versions of Intel’s 11th Gen ULP3 Core CPUs with up to 64GB DDR4-3200, 3x M.2, 1GbE and 2.5GbE ports, and optional “IET” expansion. Avalue, which recently launched a pair of NUC-APL mini-PCs based on Intel’s Apollo Lake, announced a larger, but similarly […]

'First of many new programs,' says biz, but it is no substitute for free CentOS. Red Hat, which is killing CentOS Linux in favour of CentOS Stream, will extend its developer subscription to allow free production use of RHEL for up to 16 systems.…

Organizations from all industries and of all sizes strive to deliver quality software solutions faster. This guarantees not only their survival but also success in the global marketplace. DevOps can help them chart an optimal course. DevOps is a system where different processes are supported by tools that work in a connected chain to deliver projects on time and at a lower cost.

It is often necessary to know the type of filesystem created on a hard disk or a USB thumb drive even before mounting it. For example, you may need to explicitly specify filesystem type when mounting a disk device, or have to use a filesystem-specific mount command.

Every year, my wife's book club has a book exchange during the holidays. Due to the need to maintain physical distance in 2020, I created an online gift exchange for them to use during a book club videoconference. Apparently, the virtual book exchange worked out (at least, I received kind compliments from the book club members), so I decided to share this simple little hack. How the book exchange usually works In past years, the exchange has gone something like this: read more

Copperhill’s $99 “PiCAN-M” HAT for the Raspberry Pi provides CAN-based NMEA 2000 and RS-422 driven NMEA 0183 ports for marine applications. The HAT includes a 3A SMPS supply and a Qwiic link. In 2019, Copperhill Technologies launched a PiCAN3 CAN-Bus HAT for the Raspberry Pi 4. The new PiCAN-M (for Marine), built for Copperhill by […]

I believe edge computing, which "brings computation and data storage closer to the location where it is needed to improve response times and save bandwidth," is the next major phase of technology adoption. The widespread use of mobile devices and wearable gadgets and the availability of free city-wide WiFi in some areas create a lot of data that can provide many advantages if used properly.
