Fedora, Red Hat and IBM: FSTRIM, Java APIs and DAX

  • Fedora 32 Greenlit For Enabling FSTRIM Support By Default

    Back in December was the proposal to finally enable FSTRIM by default for Fedora 32 in benefiting solid-state storage. Today the formal approval was given by the Fedora Engineering and Steering Committee to go ahead with this long overdue change.

    The change is to enable the systemd fstrim.timer unit by default for running FSTRIM weekly on EXT4/XFS/Btrfs/F2FS file-systems running on flash-based storage devices. FSTRIM is used for notifying the underlying storage devices about unused blocks for wear leveling and more efficient handling.

  • Red Hat urges U.S. Supreme Court to support unrestricted use of software interfaces

    Today, Red Hat filed an amicus brief (a "friend of the court" brief) asking the U.S. Supreme Court to overturn the U.S. Court of Appeals for the Federal Circuit decision in Oracle v. Google. The lower court incorrectly extended copyright protection to software interfaces. If left uncorrected, the lower court rulings could harm software compatibility and interoperability and have a chilling effect on the innovation represented by the open source community.

    As the world’s largest developer of enterprise open source software solutions, Red Hat’s customers include more than 90% of the Fortune 500. Using a community-powered approach to software development, Red Hat has developed reliable, high-performing, enterprise-quality cloud, middleware, storage, and virtualization technologies.

    Red Hat also has a long and extensive history of developing software written in Java as well as implementations of the Java programming language. Red Hat’s significant involvement with Java development over the last 20 years has included extensive contributions to OpenJDK, an open source implementation of the Java platform, and the development of Red Hat Middleware, a suite of Java-based middleware solutions to build, integrate, automate and deploy enterprise applications.

    [...]

    "The Federal Circuit’s unduly narrow construction of 17 U.S.C. § 102(Cool is harmful to progress, competition, and innovation in the field of software development," Red Hat stated in the brief. "IBM and Red Hat urge the Court to reverse the decision below on the basis that 17 U.S.C. § 102(Cool excludes software interfaces from copyright protection."

  • Announcing new data sets on the IBM Data Asset eXchange

    The IBM® Data Asset eXchange (DAX) is an online hub for developers and data scientists to find carefully curated free and open data sets under open data licenses. A particular focus of the exchange is data sets under the Community Data License Agreement (CDLA). Since launching the exchange in 2019, the CODAIT team has been working on steadily adding new data sets to the exchange.

    [...]

    To make it easier to use data sets on the Data Asset eXchange, we’ve introduced interactive notebooks hosted on Watson Studio that illustrate how to get started with your first steps of exploratory data analysis. Right now, we’ve added notebooks for a few data sets, including Fashion-MNIST, JFK Weather, PubTabNet, PubLayNet and more.

    We’re working on more content related to data cleansing, exploratory analysis, and machine learning with data sets from the Data Asset eXchange, so watch this space! We encourage you to check out these recent data sets and notebooks as well as all of the other data sets.

Easy Librem 5 App Development: Flashlight

In my first post on easy application development on the Librem 5 I discussed how to turn a simple shell script that takes a screenshot into a full graphical app with only a few extra lines of code. In this post I will follow up with an even simpler application that took about twenty minutes to write with much of that time involved in reading documentation. My Bright Idea The interesting thing about smart phones is how many other devices they have replaced beyond a regular phone. For instance, there used to be a market for small, pocket-sized digital cameras, but now many people just use the cameras on their smart phones. While some people still do keep a pocket flashlight with them, many people just use the light on their smart phone. I realized that a flashlight app would be another great way to showcase just how easy it is to develop applications for the Librem 5. As applications go the requirements are pretty simple: you need a button to turn on the light, a button to turn off the light, and a button to close the app. Read more

LibreOffice Writer Articles and Improvements

  • Two alternatives to Microsoft Word that are free and customizable

    If you're looking for an open-source office suite, LibreOffice is the software package for you. Its word processing program is LibreOffice Writer--which, incidentally, this story was written with, so I can attest to its excellence. You're able to choose from different fonts and text styles, embed images and figures, and use a variety of other functions you'd expect from its paid competition. It can save files in an Open Document Format (ODF), a number of Word formats, and export your work as a PDF for wide-ranging compatibility.

  • Improved rotated text handling in Writer's table rows with automatic height

    Writer now has better support for rotated text in tables containing rows with automatic height. This post also presents two related fixes. First, thanks Otevřená města who made this work by Collabora possible. [...] Before diving into improved rotated text handling, first a continuous section break import problem (tdf#128605) was fixed: this was a case when we created a new page style, but only a new section was intended.
