Zim: A Wiki-Like Note-taking App That Makes Things Easier

Filed under
Software

Zim is undoubtedly one of the best note-taking apps for Linux but it’s not just another ordinary note app that lets you add ideas/tasks and save them.

It’s tailored to help you maintain a collection of notes in the form of wiki pages. In other words, you can have a lot of notes (tasks/ideas) and link them to each other that will make it easier to go through what you’ve added in the past.

Here, I’ll give an overview of the features you get with Zim and how to get it installed on Linux.

  • HomeBank 5.4.3

    HomeBank is a free software (as in "free speech" and also as in "free beer") that will assist you to manage your personal accounting. It is designed to easy to use and be able to analyse your personal finance and budget in detail using powerful filtering tools and beautiful charts. If you are looking for a completely free and easy application to manage your personal accounting, budget, finance then HomeBank should be the software of choice.

  • Browsh

    There is a new application available for Sparkers: Browsh

    What is Browsh?

    Browsh is a fully interactive, real-time, and modern text-based browser rendered to TTYs and browsers… …Browsh is different in that it’s backed by a real browser, namely headless Firefox, to create a purely text-based version of web pages and web apps. These can be easily rendered in a terminal or indeed, ironically, in another browser. Do note that currently the browser client doesn’t have feature parity with the terminal client.

  • Kate - Color Themes

    Two years ago, we migrated our syntax highlighting to KSyntaxHighlighting. That was some work done mostly at the Akademy 2018.

    What we didn’t touch during that port: KSyntaxHighlighting has an own color theme concept that allows more or less all that we did support in KTextEditor but on the base of much better defined JSON .theme files.

    This means you can now have a theme being self-contained in a small file and you need not to import it somewhere into a large configuration mess but just place it like a highlighting definition file in some folder in either the system-wide or user-wide XDG directory “org.kde.syntax-highlighting/themes”.

    If you use KSyntaxHighlighting or KTextEditor in your own application, you can even just bundle these themes as Qt resources in “:/org.kde.syntax-highlighting/themes” inside your application binary. This simplifies bundling of own themes a lot.

    Starting with Frameworks version 5.75 we will start to make use of this variant of color themes. KSyntaxHighlighting themes now show up as color themes inside KTextEditor based applications like Kate and are usable out of the box. The change was done in this merge request.

    The UI is changed to call this “Color Theme” instead of “Schema”, the font choosing is decoupled from this now in the settings dialog. Color themes can only alter the coloring and text attributes like bold/italic/underline/…, but not switch the font itself.

    Per default the default color theme for KTextEditor based applications in now automatically selected based on the configured KDE color theme, e.g. for dark themes you will get a dark theme per default, for light themes a light one.

  • Chrome 87 Dev Builds Trying Again With X11+Wayland Ozone Enabled

    While Chrome 86 entered beta with many features, Chrome 87 in development has re-enabled the Wayland+X11 Ozone support as another attempt at improving the Wayland support experience off the single binary.

    As of the Chrome/Chromium 87.0.4252.0 dev build, the support has been relanded for using X11 and Ozone and fixes Vulkan tests on Linux with the Skia renderer as well as ANGLE tests on Linux Ozone.

A primer on GtkListView

Development
Red Hat
Software
GNOME

Some of the early adopters of GTK4 have pointed out that the new list widgets are not the easiest to learn. In particular, GtkExpression and GtkBuilderListItemFactory are hard to wrap your head around. That is not too surprising – a full list widget, with columns, and selections and sorting, and tree structure, etc is a complicated beast.

But lets see if we can unpack things one-by-one, and make it all more understandable.

The 5 Best Free and Open-Source PDF Editors

Filed under
Software

It is often the case that professionals prefer using the Portable Document Format (PDF) for all their official documents, whether it be school certificates, job letters, or important announcements. The reason why this file format is loved so much could be attributed to the fact that its formatting doesn’t get altered on any device and not to mention, it leaves a digital footprint on being edited, which isn’t the case with other file formats such as .docx, .txt, or .rtf.

Although PDFs can be easily created with software with a bunch of apps, you’d need separate tools if you want to edit them. Adobe Acrobat is one such option, but we have to tell you that it’s neither free nor open-source. So, if you’re not interested in purchasing a PDF editing software, you’ve headed to the right article. Today, we are going to be having a look at some of the best free and open-source PDF editors that you can find in 2020.

Best Free and Open Source Software

Filed under
Software
OSS

This is the largest collection of recommended software. The collection includes hundreds of articles, with comprehensive sections on internet, graphics, games, programming, science, office, utilities, and more. Almost all of the software is free and open source.

The original objective in starting the compilation was to dispel the FUD that Linux does not have the necessary software to compete with Windows. Over time, the aim of the compilation was to enable Linux users, whatever their level of computing experience, to identify software of all types that is worth exploring. With the huge range of open source software available, there is simply not enough time for users to evaluate every application even within a single category of software.

They’re all dependent on open source software.  That would be a great answer and correct, but it doesn’t tell the whole story. A complete answer is these industries not only depend on open source, but they’re building open source into the fabric of their R&D and development models. They are all dependent on the speed of innovation that collaborating in open source enables.

  • Ceph scales to 10 billion objects

    Ceph, the open source integrated file, block and object storage software, can support one billion objects. But can it scale to 10 billion objects and deliver good and predictable performance? Yes, according to Russ Fellows and Mohammad Rabin of the Evaluator Group who set up a Ceph cluster lab and, by using a huge metadata cache, scaled from zero to 10 billion 64KB objects. In their soon-to-be published white paper commissioned by Red Hat, “Massively Scalable Cloud Storage for Cloud Native Applications”, they report that setting up Ceph was complex – without actually using that word. “We found that, because of the many Ceph configuration and deployment options, it is important to consult with an experienced Ceph architect prior to deployment.”

  • Start contributing to open source Call for Code projects

    Jumping into the open source world can be intimidating for the uninitiated. Don’t let fear of the unknown stop you from getting involved in open source. In this blog post, we cover some of the basics you need to know before contributing your first line of code. [...] Now that you understand that basic gist of open source, let’s go a little deeper. While some open source projects are small developer tools that help you accomplish a single task, other open source projects are large, complicated pieces of software that have interconnected parts. In these larger projects, different teams or working groups focus on developing specific parts of the technology, collaborating on the technology, peer reviewing and testing the code, and contributing their changes to the core tech.

  • Build Smart on Kubernetes World Tour: Developers’ path to platform freedom

    Without a doubt, Kubernetes is one of hottest open tech projects today and has been so for many years now. The reason for its durable, not-so-secret success? It’s the ability to containerize code, which frees developers from the constraint of writing code for one platform only and instead gives you the freedom of write-once, deploy-anywhere development. And why is this important? Enterprises know that the fastest route to app modernization depends on the ability to develop solutions that protect current tech investments, which likely run across multiple cloud platforms on and off premises. In other words, success depends on your ability to build solutions once and deploy them across multiple hybrid cloud platforms. Yep, containers tech delivers all of that and more. With that baseline, I’m writing to let you know that when it comes to learning Kubernetes, the IBM Developer advocates team has you completely covered with the Build Smart on Kubernetes World Tour. Since we launched the World Tour back in the fall of 2019, the team has delivered literally hundreds of free hands-on workshops globally to teach developers about the power of Kubernetes. It’s all part of the IBM Developer Way, delivering on our sole mission to teach the world’s developers about open tech through hands-on workshops and supporting content such as blog posts, tutorials, and videos. With the recent launch of new content on the Build Smart on Kubernetes World Tour site, it feels like a good time to provide a quick virtual tour of all that the site offers. Visit the updated site to find more than just upcoming tour events, but also self-paced learning options. You can now choose whether you learn at your own pace by viewing recorded content, register for upcoming live events, or, even better, both. I’m going to review each section to show you the details.
