PineTime Smartwatch and Good Code Play Bad Apple

Filed under
Gadgets

PineTime is the open smartwatch from our friends at Pine64. [TT-392] wanted to prove the hardware can play a full-motion music video, and they are correct, to a point. When you watch the video below, you should notice the monochromatic animation maintaining a healthy framerate, and there lies all the hard work. Without any modifications, video would top out at approximately eight frames per second.

To convert an MP4, you need to break it down into images, which will strip out the sound. Next, you load them into the Linux-only video processor, which looks for clusters of pixels that need changing and ignores the static ones. Relevant pixel selection takes some of the load off the data running to the display and boosts the fps since you don’t waste time reminding it that a block of black pixels should stay the way they are. Lastly, the process will compress everything to fit it into the watch’s onboard memory. Even though it is a few minutes of black and white pictures, compiling can take a couple of hours.

Open Invention Network Legitimising More Software Patents (Instead of Fighting Them)

  • Open Invention Network expands Linux patent protection [Ed: IBM- and Microsoft-funded front -- fronting for OIN and Linux Foundation agenda -- continues to promote software patents agenda]

    Today, everyone -- yes, even Microsoft -- use Linux and open-source. It's been years since Linux was under attack by SCO for imaginary copyright violations, and then Microsoft CEO Steve Ballmer claimed that Linux violated over 200 of Microsoft's patents. So over 15-years ago, the Open Invention Network (OIN) patent consortium was formed to defend Linux against intellectual property (IP) attacks. Even so, Linux and open-source software are still under attack from patent trolls and other attackers. That's where the Open Invention Network (OIN) steps up by expanding its patent non-aggression coverage by updating its Linux System definition.

  • Open Invention Network Expands its Patent Non-Aggression

    Open Invention Network (OIN), the largest patent non-aggression community in history, announced today that it has increased its patent non-aggression coverage through an update to its definition of the Linux System. To keep pace with innovation Open Invention Network regularly revises and expands its Linux System coverage. This is the ninth expansion of the software packages and libraries protected under the Open Invention Network cross license.

  • Open Invention Network expands coverage

    The Open Invention Network has announced an expansion of its "Linux System Definition", which is the set of software covered by its patent-protection umbrella.

IBM/Red Hat Leftovers

  • Red Hat Insights Resource Optimization is released

    Last summer we released the public beta of the Resource Optimization service. During public beta, we received a lot of feedback from customers, which we used to enhance Resource Optimization in several areas. We are now announcing that this service is generally available for our Red Hat Enterprise Linux (RHEL) customers.

  • Automating DNS based GSLB with Infoblox DTC and Red Hat Ansible Automation Platform

    Companies are pushing data closer and closer to the edge to meet the demands of users who are increasingly sensitive to delays in application responsiveness. These changes to the way data is delivered and consumed presents challenges to IT organizations. In this post we'll talk about how an organization can provide optimum uptime while also delivering data as quickly as possible. An Application Delivery Controller (ADC) is one solution, but it often relies on expensive software and hardware to direct network traffic to available resources across datacenters. In addition to the traditional DNS infrastructure, an ADC solution often employs Global Server Load Balancing (GSLB) to dynamically reply to a Domain Name System (DNS) query with the IP address of the closest, or healthiest, server. Beyond the monetary cost of maintaining two separate DNS solutions, an ADC introduces another layer of complexity to a network.

  • Artificial Intelligence (AI): 7 trends to watch for in 2022

    Of the many technologies with the potential to deliver significant value in the near future, Artificial Intelligence (AI) seems firmly planted atop the list for CIOs. Indeed, nearly all (95 percent) of the CIOs, CTOs, and technology leaders surveyed by IEEE agreed that AI will drive the majority of innovation across almost every industry sector in the next one to five years. "In 2022, expect AI engagements to become larger, more strategically significant, and more mission-critical – with a focus on long-term scalability."

  • Future of work: A case for the 3-day weekend

    Since around 2010, the “future of work” has been a leading topic for business leaders, entrepreneurs, and employees. A key question has been how emerging technologies such as AI, robotics, and smart machines will affect humans in the workforce. Then COVID-19 struck. Seemingly overnight, orderly debates about the future of work morphed into chaotic discussions about the “present of work:” Specifically, could employees work securely using mature technologies like video conferencing, mobile telephony, and cloud computing services? Forced to shut down their physical offices, corporations resorted to work models predicated on what futurist Carmen Alfonso Rica called a “massive, forced adoption of remote working.”

  • Record your terminal with script and scriptreplay

    A fascinating thing about humans is that we each have a particular learning style. Some people prefer to read about how something's done. Some people prefer to follow instructions from the start, while others prefer to get an overview before engaging. Other people like to listen to instructions from an instructor or a podcast. And yet another group wants instructions in the form of a video. The trouble with video is that it can be difficult to produce and compress, and it is a lot of work to change once it's done. And besides that, viewers can't copy and paste Linux commands out of a video into their terminal. [...] The script and scriptreplay commands allow you to record a terminal session and then play it back later. There's no video involved. Instead, plain text files called typescripts are used, so the files are small and users can copy commands during playback.

  • How to install FirewallD GUI on Rocky Linux 8 | Almalinux 8 - Linux Shout

    Here in this article, we learned the simple steps and commands to install a graphical user interface (GUI) to manage FirewallD on either Alamlinux or Rocky Linux 8. However, the steps are the same for CentOS, Redhat, Oracle Linux, and other RPM-based distros. FirewallD is a command-line tool to provide a system firewall feature to protect Linux unwanted access by disabling and enabling ports and services access to outside or local networks. However, if you are using a Graphical interface user then the command line may seem a little bit difficult to use. Therefore, to make things easy we can use GUI tools available to manage FirewallD such as one from firewall-config or Plasma firewall
