  • Why Testing Is Important for Distributed Software

    As developers, we often hear that tests are important. Automated testing minimizes the number of bugs released to production, helps prevent regression, improves code quality, supplements documentation, and makes code reviews easier. In short, tests save businesses money by increasing system uptime and keeping developers working on new features instead of fighting fires. While software testing has been around for about as long as software has, I would argue that testing is especially important (and unfortunately more challenging) in modern distributed software systems.

  • RcppArmadillo 0.8.100.1.0
  • ConCom, and calls for programming, charity, and staff (oh my!)
  • HyperCard

    One of my favorite pastimes is imagining and planning to write new coding projects: researching technologies, checking out libraries I might use, making GUI mockups, downloading similar projects.

    I was thinking the other day that it might be fun to create a desktop-based editor that had an HTTP server embedded.  The HTTP server would serve up only one document, which is the document being currently edited, and it would show a live representation of the screen as being show the person editing the document.

    I was thinking it might be fun to re-implement the old HyperCard system.

An introduction to Joplin, an open source Evernote alternative

Joplin is an open source cross-platform note-taking and to-do application. It can handle a large number of notes, organized into notebooks, and can synchronize them across multiple devices. The notes can be edited in Markdown, either from within the app or with your own text editor, and each application has an option to render Markdown with formatting, images, URLs, and more. Any number of files, such as images and PDFs, can be attached to a note, and notes can also be tagged. I started developing Joplin when Evernote changed its pricing model and because I wanted my 4,000+ notes to be stored in a more open format, free of any proprietary solution. To that end, I have developed three Joplin applications, all under the MIT License: for desktop (Windows, MacOS, and Linux), for mobile (Android and iOS), and for the terminal (Windows, MacOS, and Linux). All the applications have similar user interfaces and can synchronize with each other. They are based on open standards and technologies including SQLite and JavaScript for the backend, and Terminal Kit (Node.js), Electron, and React Native for the three front ends. Read more

Open Source OS Still supporting 32-bit Architecture and Why it’s Important

One after the other, Linux distributions are dropping 32-bit support. Or, to be accurate, they drop support for the Intel x86 32-bit architecture (IA-32). Indeed, computers based on x86_64 hardware (IA-64) are superior in every way to their 32-bits counterpart: they are more powerful, run faster, are more compact, and more energy efficient. Not mentioning their price has considerably decreased in just a few years. If you have the opportunity to switch to 64 bits, do it. But, to quote a mail I received recently from Peter Tribble, author of Tribblix: “[… ] in the developed world we assume that we can replace things; in some parts of the developing world older IA-32 systems are still the norm, with 64-bit being rare.” Read more

KDE Applications 17.12 Lands with Dolphin Enhancements, HiDPI Support for Okular

KDE Applications 17.12 has been in development for the past several months and it's now available as a drop-in replacement for the previous series of the software suite, KDE Applications 17.08, which reached end of life in early November. As expected, several of the included apps received various enhancements and new features in this release. Among these, we can mention that the Dolphin file manager is now capable of saving searches, can limit the search only to folders, makes renaming of files easier by allowing the user to simply double-click on the file name, displays extra information about files like origin URL of downloaded file or modification date, and introduces new Bitrate, Genre, and Release Year columns.
