Not to worry, zombies with a gambling addiction probably won't eat your enterprise brains Column It seemed like a classic April The First spoof. Indeed, some tech titles had it on their lists of best pranks of the day. But it's true: the software zombie court case to end all zombie software court cases has woken from its slumber. Nearly 29 years after it first lurched from the crypt, SCO v The World Of Linux is back, and it smells just as bad as ever.…

In an important victory for software developers, the Supreme Court ruled today that reimplementing an API is fair use under US copyright law. The Court’s reasoning should apply to all …

America's top judges decide copied code in Android is fair use. The US Supreme Court on Monday ruled in a 6-2 decision that Google's limited copying of Oracle's Java APIs in its Android operating system constitutes fair use under US law.…

Applications built on microservices can be scaled in multiple ways. We can scale them to support development by larger development teams and we can also scale them up for better performance. Our application can then have a higher capacity and can handle a larger workload. […]

I have several computers. I've got a laptop at work, a workstation at home, a Raspberry Pi (or four), a Pocket CHIP, a Chromebook running various forms of Linux, and so on. I used to set up my user environment on each computer by more or less following the same steps, and I often told myself that I enjoyed that each one was slightly unique. read more

Whenever I start learning a new programming language, I focus on defining variables, writing a statement, and evaluating expressions. Once I have a general understanding of those concepts, I can usually figure out the rest on my own. Most programming languages have some similarities, so once you know one programming language, learning the next one is a matter of figuring out the unique details and recognizing the differences. read more

FreeDOS, the open source implementation of DOS, provides a lightweight operating system for running legacy applications on modern hardware (or in an emulator) and for updating hardware vendor fails with a Linux-compatible firmware flasher. Getting familiar with FreeDOS is not only a fun throwback to the computing days of the past, it's an investment into gaining useful computing skills. In this article, I'll look at some of the essential commands you need to know to work on a FreeDOS system.

IEI’s fanless, rugged “DRPC-330-A7K” embedded computer runs Ubuntu on a Marvell Armada 7040 and offers 10GbE SFP+, 2x GbE, 4x isolated serial, 2x USB, and 3x M.2 connections. IEI announced a networking-oriented embedded computer called the DRPC-330-A7K that runs Ubuntu 18.10 on Marvell’s Armada 7040 (88F7040). The DIN-rail form-factor system has a -20 to 60°C […]

Version control is an inseparable part of software developers' daily lives. It's hard to imagine any team developing software without using a version control tool. It's equally difficult to envision any developer who hasn't worked with (or at least heard of) Git. In the 2018 Stackoverflow Developer Survey, 87.2% of the 74,298 participants use Git for version control.

Advantech’s rugged “UNO-238” embedded PC runs Linux or Win 10 on Intel’s 8th Gen UE-series and offers up to 32GB of easily swappable DDR4 plus 32GB eMMC, 2x GbE, 4x USB 3.2 Gen2, 2x serial, 2x M.2, and DP and HDMI. Advantech announced a fanless, Whiskey Lake based IoT edge computer called the UNO-238 that […]

Rare diseases kill millions, but because they don't make the headlines that coronavirus does, they're often ignored. Now, the Linux Foundation and the OpenTreatments Foundation are joining forces to create open-source gene therapies for rare genetic diseases.

DFRobot’s $30, 66 x 55mm “Compute Module 4 IoT Router Carrier Board Mini” extends the Raspberry Pi CM4 with 2x GbE, 2x Type-C, microSD, and 26-pin GPIO. Earlier this month, we saw the first dual-Ethernet carrier boards for the Raspberry Pi Compute Module 4 in Seeed’s Dual Gigabit Ethernet Carrier Board (2x GbE) and Mcuzone […]

RMS has been kicked off the GCC Steering Committee while FSF management team members are resigning

Finding your way around a version control system can be tricky. It can be massively overwhelming for a newbie, but being well-versed with the terminology and the basics of a version control system like Git is one of the baby steps to start contributing to open source. Being familiar with Git can also help you out of sticky situations in your open source journey. Git is powerful and makes you feel in control—there is not a single way in which you cannot revert to a working version. read more

Two common tasks that new programmers need to learn are how to read from and write to files stored on a computer. Some examples are when data and configuration files created in one application need to be read by another application, or when a third application needs to write info, warnings, and errors to a log file or to save its results for someone else to use. read more

When debugging code, you're often faced with figuring out when a variable changes. Without any advanced tools, you have the option of using print statements to announce the variables when you expect them to change. However, this is a very ineffective way because the variables could change in many places, and constantly printing them to a terminal is noisy, while printing them to a log file becomes unwieldy. read more

Main power of tcpdump packet sniffing tool comes from its flexible packet filtering rules and versatile protocol dissection capability. As you may know, only the sky is the limit when it comes to packet-level monitoring with tcpdump. This post provides a comprehensive tcpdump cheat sheet with detailed examples.

Diodes Delight has launched a $39 “Piunora” carrier for the Raspberry Pi CM4 with Arduino, ADC, and Qwiic expansion, and Mirko Electronics is prepping a “MirkoPC” carrier with dual HDMI and a DAC. Lately, it seems, most of the interesting embedded Linux news has been about carrier boards for the Raspberry Pi Compute Module 4. […]

If you use Git every day, you probably make a lot of commits. If you're using Git every day in a project with other people, it's safe to assume that everyone is making lots of commits. Every day. And this means you're aware of how disorienting a Git log can become, with a seemingly eternal scroll of changes and no sign of what's been changed. So how do you find out what file changed in a specific commit? It's easier than you think.
