  • Deploy a Java application using Helm, Part 2 | Red Hat Developer

    In the previous article in this series, you learned how to deploy Java applications to Red Hat JBoss Enterprise Application Platform (JBoss EAP) using Helm on Red Hat OpenShift. Developers can use the procedures in Part 1 to easily stand up traditional Java application servers on Kubernetes with predefined Kubernetes manifestos.

    What if you could have the same benefits when you develop microservices using JBoss EAP and Helm charts? JBoss EAP provides the Extension Pack (XP) to implement content trimming, packaging to a bootable JAR, and a MicroProfile specification including fault tolerance, monitoring, and tracing in support of microservices in the cloud. This article explains how to make a bootable JAR using JBoss EAP XP and Helm and deploy the application to OpenShift.

  • DevOps: 3 skills needed to support its future in the enterprise

    It’s no longer a question of if organizations need DevOps, but rather when they should adopt it, according to the DevOps Institute Upskilling 2021 report. That report finds that global enterprise adoption of DevOps at the project or multiple-project level is at 20 percent and 36 percent, respectively – and the skills needed for a successful DevOps journey span the categories of automation, human, technical, functional, and process knowledge.

    Whether you’re facing a skills gap in any of those key areas or you’re looking to expand your adoption of DevOps in the near future, keep the following considerations in mind:

  • Productivity lessons learned: 6 CIOs share tips for you and your team

    In our new hybrid work reality, many people in IT have enjoyed the flexibility to rewrite the rules on work-life balance. But it’s been a learning curve, says Kumud Kalia, CIO, Guardant Health.

    “As we moved to remote working for most of our employees, it became evident that time management had become much more of a juggling act between work, childcare/schooling, and miscellaneous personal priorities without a clear separation between these various activities. We already had flexible working hours for many of our employees, but we found that Zoom fatigue was real and added to the already unrelenting demands upon our people,” says Kalia.

    We asked CIOs who recently won the 2021 Bay Area CIO of the Year ORBIE Awards for their best productivity tips and lessons learned on work-life balance over the last year and a half. The awards were presented by the Bay Area CIO Leadership Association, a professional community that annually recognizes CIOs for their excellence in technology leadership.

    From being intentional and selective, to setting the right examples from the top, learn how these award-winning CIOs are making the most of their workday - and encouraging their teams to do the same.

  • Docker and Fedora 35

    In June of 2020, we published an article related to running Docker and Fedora 32. We described various workarounds that were required to run Docker, and we explained the bothersome situation at that time. But Docker has evolved, and it’s time to return to our previous tutorial. Thus, today we’ll talk about using Docker on Fedora Linux 35.

    With this guide, you should be able to easily recreate an existing development environment, without having to retool your entire pipeline. We’ll focus on getting the right packages, testing a few important scenarios, and helping you with tooling.

  • Reject Modernity; Return To Tamagotchi | Hackaday

    Browsing through the recent projects on Hackaday.io, we’ve found this entry by [NanoCodeBug]: a single-PCB low-power trinket reviving the “pocket pet” concept while having some fun in the process! Some serious thought was put into making this device be as low-power as possible – with a gorgeous Sharp memory LCD and a low-power-friendly SAMD21, it can run for two weeks on a pair of mere AAA batteries, and possibly more given a sufficiently polished firmware. The hardware has some serious potential, with the gadget’s platform lending itself equally well to Arduino or CircuitPython environments, the LCD being overclock-able to 30 FPS, mass storage support to enable pet transfer and other PC integrations, a buzzer for all of your sound needs, and an assortment of buttons to help you create mini-games never seen before. [NanoCodeBug] has been working on the hardware diligently for the past month, having gone through a fair few revisions – this is shaping up to be a very polished gadget!

  • Remoticon 2021 // Voja Antonic Makes You A Digital Designer | Hackaday

    [Voja Antonic] has been building digital computers since before many of us were born. He designed with the Z80 when it was new, and has decades of freelance embedded experience, so when he takes the time to present a talk for us, it’s worth paying attention. For his Remoticon 2022 presentation, he will attempt to teach us how to become a hardware expert in under forty minutes. Well, mostly the digital stuff, but that’s enough for one session if you ask us. [Voja] takes us from the very basics of logic gates, through combinatorial circuits, sequential circuits, finally culminating in the description of a general-purpose microprocessor.

  • Robotic Xylophone Makes Music with MIDI Magic

    The MIDI format has long been used to create some banging electronic music, so it’s refreshing to see how [John P. Miller] applied the standard in his decidedly analog self-playing robotic xylophone. Framed inside a fetching Red Oak enclosure, the 25-key instrument uses individual solenoids for each key, meaning that it has no problem striking multiple bars simultaneously. This extra fidelity really helps in reproducing the familiar melodies via the MIDI format. The tracks themselves can be loaded onto the device via SD card, and selected for playback with character LCD and rotary knob. The software transposes the full MIDI music spectrum of a particular track into a 25-note version compatible with the xylophone. Considering that a piano typically has 88 keys, some musical concessions are needed to produce a recognizable playback, but overall it’s an enjoyable musical experience.

  • The Eclipse Oniro Project aims to deliver consumer & IoT software that works across multiple operating systems - CNX Software

    So basically I understand Oniro aims to provide a vendor-agnostic platform to develop software that runs on various operating systems and hardware in order to reduce fragmentation in the consumer and IoT device industry. I will not insert an xkcd meme here, but you know what I mean. Right now, Oniro relies on the Poky/Yocto Project build system and supports three operating systems with Linux, ZephyrOS, and FreeRTOS allowing it to be used in application processors and microcontrollers.

India's government may foster home-grown mobile OS

India's minister of state for Electronics and IT Rajeev Chandrasekhar has revealed the nation's government intends to develop a policy that will encourage development of an "indigenous mobile operating system". Speaking at the launch of a policy vision for Indian tech manufacturing, Chandrasekhar said India's Ministry of Electronics and Information Technology believes the market could benefit from an alternative to Android and iOS and could "even create a new handset operating system" to improve competition, according to the Press Trust of India. "We are talking to people. We are looking at a policy for that," Chandrasekhar told local media, adding that start-ups and academia are being considered as likely sources of talent and expertise to build the OS. "If there is some real capability then we will be very much interested in developing that area because that will create an alternative to iOS and Android which then an Indian brand can grow,” he added. The minister offered no timeframe for a decision on whether to proceed with the policy, nor the level of assistance India's government might provide. Nor did he say much to suggest he knows that past attempts to create alternative mobile operating systems, or national operating systems, have cratered. Even Microsoft, famously, failed to make an impact with Windows Phone despite throwing billions at the OS and acquiring Nokia to ensure supply of handsets to run it. Mozilla's Firefox OS was discontinued after efforts to crack India's mobile market with low-cost devices failed. The Linux Foundation's Tizen hasn't found a lot of love. Read more

Keyboard Hacks With Raspberry Pi and Arduino

  • Turn On Sarcasm With the Flip Of a Switch

    Sarcasm is notoriously difficult to distinguish in online communities. So much, in fact, that a famous internet rule called Poe’s Law is named after the phenomenon. To adapt, users have adopted several methods for indicating implied sarcasm such as the /s tag, but more recently a more obvious sarcasm indicator has appeared that involves random capitalization througout the sarcastic phrase. While this looks much more satisfying than other methods, it is a little cumbersome to type unless you have this sarcasm converter for your keyboard. The device, built by [Ben S], is based around two Raspberry Pi Pico development boards and sits between a computer and any standard USB keyboard. The first Pi accepts the USB connection from the keyboard and reads all of the inputs before sending what it reads to the second Pi over UART. If the “SaRcAsM” button is pressed, the input text stream is converted to sarcasm by toggling the caps lock key after every keystroke.

  • Reverse engineering an '80s NeXT keyboard | Arduino Blog

    Working with vintage computer technology can feel a bit like the digital equivalent of archeology. Documentation is often limited or altogether absent today — if it was ever even public in the first place. So you end up reverse engineering a device’s functionality through meticulous inspection and analysis. Spencer Nelson has a vintage NeXT keyboard from the ’80s and wanted to get it working with modern computers via USB. To make that happen, he reverse engineered the protocol and used an Arduino as an adapter. NeXT was a computer company founded by Steve Jobs in the ’80s, in the period after he left Apple. A little over ten years later, Apple bought NeXT and Jobs rejoined the company. NeXT only released a few computers, but they are noteworthy and desirable to collectors. This particular keyboard is from 1988 and worked with the first generation NeXT Computer. Unlike modern keyboards that share the USB protocol, keyboards from this era utilized proprietary protocols. This particular model had an enigmatic protocol that Nelson became obsessed with deciphering.

  • Reverse Engineering The NeXT Computer Keyboard Protocol | Hackaday

    The NeXT computer was introduced in 1988, with the high-end machine finding favor with universities and financial institutions during its short time in the marketplace. [Spencer Nelson] came across a keyboard from one of these machines, and with little experience, set about figuring out how it worked. The keyboard features a type of DIN connector and speaks a non-ADB protocol to the machine, but [Spencer] wanted to get it speaking USB for use with modern computers. First attempts at using pre-baked software found online to get the keyboard working proved to be unreliable. [Spencer] suspected that the code, designed to read 50 microsecond pulses from the keyboard, was miscalibrated.
