  • Scaling PostgreSQL with Kubernetes Operators

    Crunchy Data's open source Crunchy PostgreSQL Operator is an Operator for PostgreSQL that is used in many production environments. It provides a simple yet powerful command-line interface that lets users deploy their own database-as-a-service system on any Kubernetes-enabled platform.

    For example, with the pgo create command, which is used to provision a database, you can set up a distributed, high-availability PostgreSQL cluster with full disaster recovery support along with a database monitoring sidecar powered by pgMonitor. In other words, in lieu of a complicated multi-step process or having to write your own scripts, you can create the type of PostgreSQL system required for production from a single command.

    While this may seem to be overkill if you are managing a handful of database clusters, the value of an Operator scales significantly if you need to support hundreds or thousands of different clusters. Having a standardized set of commands with the ability to flexibly deploy clusters for different workloads both eases the administration burden and provides more options for how a team can develop and deploy workloads into production.

  • Today's Context Demands Use of OER

    This movement is the most exciting thing to happen to higher ed in my lifetime. It brings together the humanity, respect for students (and instructors!) and impetus to make a positive change in students’ lives from thinkers like bell hooks, Paulo Freire and John Dewey with the technological know-how and thirst for openness, access and justice of Seymour Papert, Richard M. Stallman and Aaron Swartz.

    There is no point in my parodying the eloquence of the expositors of open pedagogy cited above -- please go read them right now, if you haven’t yet. But one thing I can do is add a small point I haven’t see those authors emphasize, in the spirit (following Green) of exploring what motivates faculty. One thing that faculty members love (perhaps particularly at primarily research institutions, where they may be worried about something with enormous impact on pedagogy but which will require a large investment of their time) is their academic freedom.

  • AMDGPU LLVM Backend Seeing A Number Of Fixes In Recent Days

    If you habitually use the latest open-source graphics drivers, you may want to pull down the latest LLVM code from SVN/Git as there has been a number of fixes to the AMDGPU back-end in recent days.

    For those that haven't upgraded in a while or perhaps still on the LLVM 8 code-base, the latest LLVM 9 development code has been seeing a number of AMDGPU commits during the second half of February. There's been enabling of function calls by default that fixes some crashes, other crash fixes, implementing various features, enabling the DPP combiner pass by default, and other bits.

  • Include the currency name into the forex application

    Hello and welcome back to this new python forex application project. In the previous chapter, we have successfully retrieved the name and the id pair for all the conbase supported currencies, and in this chapter, we will use that information to add the currency name beside each currency id when we are comparing that currency to the USD. Below is the modify version of this program.

  • IRC vs IRL: How to run a good IRC meeting

    There's an art to running a meeting in any format. Many people have learned to run in-person or telephone meetings, but Internet Relay Chat (IRC) meetings have unique characteristics that differ from "in real life" (IRL) meetings. This article will share the advantages and disadvantages of the IRC format as well as tips that will help you lead IRC meetings more effectively.

    Why IRC? Despite the wealth of real-time chat options available today, IRC remains a cornerstone of open source projects. If your project uses another communication method, don't worry. Most of this advice works for any synchronous text chat mechanism, perhaps with a few tweaks here and there.

  • 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.
