IBM/Red Hat: systemd, chatbots, remote work and why Java and Quarkus are important for your business

  • systemd-oomd Looks Like It Will Come Together For systemd 247

    Systemd-oomd is the out-of-memory daemon developed by Facebook and systemd developers. They are aiming for this to be better Linux handling of out-of-memory / low memory situations. Facebook originally wrote their OOMD code for their servers and since then has continued to be refined and adapted so it works out equally as well on desktops and more.

    Systemd-oomd polls systemd for OOMD-enabled cgroups to monitor them and kill based on memory pressure or swap usage. The systemd-oomd behavior is controlled via a new oomd.conf configuration file. Cgroups will need to employ EnableOomdKill if they want to be killed when under pressure.

  • 8th grader creates Watson-powered chatbot to help students plan for college during COVID-19

    When eighth-grader Harita Suresh found herself stuck at home due to the coronavirus, she decided to use her extra time to learn something new. After perusing edX.org, she settled on a course from IBM called AI chatbots without programming, which claimed that she would be able to build a fully functional chatbot with no prior knowledge about AI.

    Two weeks later, she’d used her newfound knowledge to create and launch a fully functioning chatbot — Rita — for her dad’s business, Analyze-Ed.

  • 3 best practices for working on a distributed team

    I have mixed feelings about instant messaging platforms. Pulling quick conversations out of email and into Slack often does improve resolution times for small issues, but a successful rollout requires some setting of expectations. Fundamentally, I do not believe it is reasonable to expect prompt responses to IM messages during the workday. Giving employees time for focused, uninterrupted work is vital. These tools provide functionalities to customize alerts, including muting all notifications (with a configurable option that lets others force alerts through as needed), muting individual channels, setting up various keyword notifications, and a wide range of other options not covered here.

    However, these controls are meaningless if there is an organizational expectation of prompt responses. Too frequently, I see folks asking a question like "Is anyone working on the database?" and, after less than five minutes, following up with "Okay, sounds like nobody is working on it, I am going to make my changes."

    Not only does this assume everyone has the same working hours, which immediately breaks down when you have remote team members in different time zones, it also ignores the reality of work both in and out of the office. Packages get delivered, coffee needs to be prepared, meetings are attended, and, sometimes, real work is being done! Take an empathetic look at your co-workers' needs and build expectations that allow for async work.

  • Why Java and Quarkus are important for your business

    Java has been the workhorse of enterprise software application development for the past 25 years. During this time, we have also seen some drastic changes to application infrastructure technologies - ones that are not always compatible with the Java framework. We have seen it all: from monolithic application servers, to API-driven programmable infrastructure, to just-in-time intelligent serverless infrastructures. We have gone from extensive setup and dynamic configuration for peak workloads, to expressing the ideal operational model as code for our applications. Now with serverless computing, developers can focus on providing the application code and letting an intelligent application infrastructure run and scale up and down for use, without even thinking about infrastructure concerns.

    Increasingly, modern application infrastructure tends to be immutable, meaning that servers are not able to be modified after they have been deployed. Immutable infrastructure can help simplify operations and lead to simpler, more predictable, and consistent deployment processes. When changes are required, the old configuration can be replaced with a new configuration to keep the environments consistent and easily reproducible across development, test and production. However, the traditional Java framework was designed for changeable application infrastructure that is no longer required in modern cloud environments.

Games: DRAG, Valve Index kit and Inscryption

  • DRAG | Linux Gaming | Ubuntu 20.04 | Native

    DRAG running natively through Linux.

  • Sci-fi racer with fancy 4-point physics 'DRAG' is now in Early Access

    Orontes Games have finally unleashed DRAG, their sci-fi racer with advanced 4-point physics into Early Access. Note: key provided to GOL by the developer. Introducing what they say is a "new kind of vehicle-physics", their 4-way contact point traction technology (or 4CPT-technology for short) simulates every component of the vehicles in real time. The result is supposed to give you "realistic, dynamic" behaviour with a full damage model, so expect to see wheels flying across your screen when in multiplayer.

  • My experiences of Valve's VR on Linux

    As the proud and excited owner of a shiny new Valve Index kit to go with my almost-new all-AMD rig, I thought I’d outline the journey to getting it all working, exclusively on Linux. Now bear in mind that I’m not amazingly Linux-savvy. I’ve been using it since the early 2000’s, sure, and full time, exclusively, since 2013, but I’m not very interested in learning the guts of this stuff. I’m extremely technical as a network nerd, but my O/S is just a tool to let me run cool things. I want to be a “normal” consumer of that O/S and if things don’t work out of the box, I take a dim view of it and I don’t have a lot of patience for terminal hacks or “compiling my own kernel”.

  • Inscryption from the developer of Pony Island has a new trailer

    Inscryption from Daniel Mullins Games (Pony Island, The Hex) sounds absolutely wild and it's got a brand new trailer but we've got quite some time to wait on it. Based upon the title Sacrifices Must Be Made, which Mullins made for the Ludum Dare 43 Game Jam, Inscryption is described as an "inky black card-based odyssey that blends the deckbuilding roguelike, escape-room style puzzles, and psychological horror into a blood-laced smoothie".

LibreOffice 7.0: A week in stats
