  • Postgres set-returning functions that self-memoize as materialized views

    In episode 2 I mentioned three aspects of pl/python that are reasons to use it instead of pl/pgsql: access to Python modules, metaprogramming, and introspection. In episode 5 I discussed metaprogramming, by which I mean using pl/python to compose and run SQL code. This episode features introspection, by which I mean taking advantage of Python’s inspect module to enable a pl/python function to discover its own name.

  • Let's write a compiler, part 6: Input and output

    Now armed with a complete PL/0 compiler, we have a few last bits to clean up. The one I want to cover today is basic input and output. For us, that will mean the ability to print number and input numbers. Shorter than yesterday for sure, but very useful.

    We won't be printing strings today. That will come later. You can fake it for now with repeated character printing.

  • [Perl statistics] Monthly Report - July

    The guilt is killing me every time I delay the monthly report. I finally found time to get this out on 22nd day of the month where I would do that on the very first day of the month in the past.

    Life can be challenging at times, balancing personal and professional aspect can be difficult, I must confess.

    In all of these up and down, I have to keep myself motivated and find ways to stay happy.

    I try to avoid negative thoughts coming on my way and stay positive.

  • Academy Software Foundation onboards Maxon and Tangent Animation as general members

    Recently, the Academy Software Foundation (ASWF), the preeminent organization for open source software development in the motion picture and media industries, announced the addition of two new general members: Maxon and Tangent Animation. The news comes as the Academy Software Foundation heads into its annual conference, Open Source Days, a free virtual event which will be held on 4 and 5 August where top Hollywood studios and technology developers come together to share the latest progress on open source tools and standards.

    [...]

    The addition of Maxon and Tangent Animation marks continued growth for the ASWF, following the addition of Adobe and the Entertainment Technology Center@USC as members earlier this year. The ASWF has grown significantly in just three years, from 13 founding members to 33 members today, a testament to the importance and scope of open source development across the industry.

  • 25 Years Later: The Original Quake Gets a Remaster for PC and Consoles

    The first installment in the Quake game series arrived in 1996, a full 25 years ago, when id Software partnered with GT Interactive to publish one of the most game-changing game series of all time. The game implemented new technologies (at that time) like 3D acceleration through OpenGL, and later on, brought support for multiplayer.

    Presented at today's virtual QuakeCon conference, id Software and Machine Games partnered to develop a Quake remaster with various visual improvements for nostalgic players.

  • Intel's IWD 1.17 Wireless Daemon Brings More Fixes - Phoronix

    While it was busy on the hardware side of the house with Intel talking up all of their forthcoming hardware, Intel's open-source software engineers remain very busy working not only to enable their next-generation hardware but other open-source efforts they've invested in like the iNet wireless daemon.

    IWD has matured well on Linux the past few years as a possible replacement to WPA Supplicant and can integrate with the likes of NetworkManager, systemd-networkd, and Intel's own ConnMan project too.

  • 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.
