  • Announcing syntreenet: A library to build scalable production rule systems

    Perhaps some of you might be interested in this library I've released, that can be used to build production rule systems, with the peculiarity that the cost of matching a fact to the knowledge base is logarithmic in the size of said knowledge base, measured as the number of rules plus the number of facts in working memory. As far as I know, the current state of the art is polynomial.

  • Your first GUI app with Python and PyQt

    Many people struggle with learning how to build a GUI app. The most common reason is, they don’t even know where to start. Most tutorials are purely text based, and it’s hard to learn GUI development using text, since GUIs are mainly a visual medium.

    We will get around that by building a simple GUI app, and show you how easy it is to get started. Once you understand the basics, it’s easy to add advanced stuff.

  • Stephen Michael Kellat: Early July Quick Bits

    I have been moving repositories off Github to Launchpad and deleting the old repositories on Github. It probably is not the best practice to outright delete repositories on Github but I would rather concentrate things on Launchpad.

  • When The Times First Says It, This Twitter Bot Tracks It

    There is, however, a person behind the account: Max Bittker, a 24-year-old Google software engineer who built the program. “I’m most interested in uses of programming that are weird or interesting or artistic,” Mr. Bittker said in a recent telephone interview. “One of them is Twitter bots, but also data visualization for journalism, text analysis and that kind of thing.”

    Mr. Bittker built the first version of the program in a weekend or two, he said, helped substantially by open-source code for a project called NewsDiffs, which records changes to online news articles. It was built by three coders, including the former New York Times journalist Jennifer 8. Lee, who made the source code available to other engineers. That allowed Mr. Bittker to create a “fork,” or new project, off the same framework.

    The initial draft was followed by a long period of refinement, to “filter out things that were not interesting,” Mr. Bittker said. “It would tweet every URL and proper nouns and things like that.” These days, a number of heuristics limit what the bot will tweet: no capital letters, dashes, underscores or @ symbols.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
