  • KNewPasswordWidget lands in KWidgetsAddons

    A new widget called KNewPasswordWidget has been added to the KWidgetsAddons framework, starting from 5.16. I decided to create this widget because sometimes you cannot just use KNewPasswordDialog to ask the users for a new password. This is the case when you need to add further options to the same dialog. This widget is meant to be easily embedded in such a custom password dialog, without having to code it from scratch.

  • Handing over the reins

    As some of you might know, I started the application Cantor in KDEedu a couple of years ago, since I didn’t want to rely on comercial computer algebra systems during my studies, and because all the free alternatives seemed to lack a decent graphical interface. Since then Cantor has grown to support all kinds of different mathematical languages due to numerous contributors from all over the world.

  • fwupd and DFU

    Once all this new code has settled down I’m going to be re-emailing a lot of the vendors who were unwilling to write vendor-specific code in fwupd. I’m trying to make the barrier to automatic updates on Linux as low as possible.

  • PaperTrail - Powered by IBM Watson

    On the final semester of my MSc program at Columbia SEAS, I was lucky enough to be able to attend a seminar course taught by Alfio Gliozzo entitled Q&A with IBM Watson. A significant part of the course is dedicated to learning how to leverage the services and resources available on the Watson Developer Cloud. This post describes the course project my team developed, the PaperTrail application.

    Google has many side initiatives, and one of them is the Cultural Institute that digitizes works of art from museums and archives around the world and puts them online.

    Today, their Art Project released an app for Chrome OS that updates the wallpaper of your device to a different piece of art from their collection every day. Expect “masterpieces ranging from Van Gogh and Monet, all the way to contemporary works from street artists around the world,” according to Chrome evangelist François Beaufort in announcement post.

  • Blogging, Podcasting, or Video?

    While I was initially attracted to the notion of sharing some of these thoughts in an audio format, I have decided to focus instead more on writing. This was partially informed by my back of the napkin research, but also in thinking about how we best present thoughts.

  • Linux AIO: Ubuntu 15.10 available

    Linux AIO is a project to package multiple flavours of a distribution in one ISO within a DVD size limit. Users can try each flavour live or install on their systems. In essence the difference lies mostly in the desktop environments. This is an invaluable source of distributions for distro hoppers. Note that there are issues, some of which are unresolved due to distro dependencies. However, for most of it, the stuff works.

  • NAS boxes double as media players, run Linux plus Android

    Qnap’s TAS-168 and dual-bay TAS-268 NAS devices run both Linux and Android on a dual-core ARM SoC, and offers private cloud and media player capabilities.

    Qnap is positioning the single HDD-bay TAS-168 and dual-bay TAS-268 at the bottom of its Home NAS line below the faster, dual-bay TS-231 and the higher-end, dual-bay TS-251 launched in 2014. Like these systems, the new TAS devices are mini-towers and run Qnap’s Linux-based NAS OS. In addition, Qnap claims the devices are the first home network-attached storage devices that also run Android.

  • 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.
