  • Excellent Free Tutorials to Learn VimL

    VimL is a powerful scripting language of the Vim editor. You can use this dynamic, imperative language to design new tools, automate tasks, and redefine existing features of Vim. At an entry level, writing VimL consists of editing the vimrc file. Users can mould Vim to their personal preferences. But the language offers so much more; writing complete plugins that transform the editor. Learning VimL also helps improve your efficiency in every day editing.

    VimL supports many common language features: variables, control structures, built-in functions, user-defined functions, expressions first-class strings, high-level data structures (lists and dictionaries), terminal and file I/O, regex pattern matching, exceptions, as well as an integrated debugger. Vim’s runtime features are written in VimL.

    VimL is often known as Vimscript or Vim script.

  • RcppCCTZ 0.2.7

    RcppCCTZ uses Rcpp to bring CCTZ to R. CCTZ is a C++ library for translating between absolute and civil times using the rules of a time zone. In fact, it is two libraries. One for dealing with civil time: human-readable dates and times, and one for converting between between absolute and civil times via time zones. And while CCTZ is made by Google(rs), it is not an official Google product. The RcppCCTZ page has a few usage examples and details. This package was the first CRAN package to use CCTZ; by now at least three others do—using copies in their packages which remains less than ideal.

  • JavaFX 14 enhances API, mobile support

    JavaFX 14, the latest version of the open source, Java-based, rich client application platform, has arrived. The new version features improvements related to the top-level API as well as mobile development.

    For the API, functionality was added to make it easier for developers to build custom controls. In the mobile vein, JavaFX for mobile SDKs are now built from OpenJFX, the same source as for desktop JavaFX. Combined with the GraalVM native image AOT (ahead-of-time) compiler, JavaFX now achieves high performance on mobile, while developers can use the same JavaFX APIs for mobile as for the desktop.

  • Join Our Second Documentation Hackathon March 22-30

    Documentation is extremely valuable to the health of open source software projects, but it is often overlooked. We are a small team at Tor, and as a nonprofit organization with a big mission, we rely on volunteer contributions around the world to keep up with an ever-changing [Internet] freedom landscape with the appropriate tools to navigate it. Keeping Tor's documentation up-to-date, organized, and accessible is a way to potentially help millions of people access a private, secure, and uncensored [Internet] by using our tools.

    Between 22 and 30 March, the Tor Project will host the second edition of our user documentation hackathon, the DocsHackathon. The DocsHackathon is a totally remote and online event.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
