  • Paging for Fun and Profit

    Egad have been away for a while, it is not due to laziness on my part, I really have been stuck on a Paws problem over the past month+, add to that dozens of inside and out sided projects that I need to get done around the house time has just not been there. At least I have finally cracked it.

    I really went down a rabbit hole for this one and spend way too many hours trying to figure out how to test 'Paws Pagination' end to end.

    In my last post I started out with a new test suite '30_pagination.t' and a few test YAMLs. Just getting the YAML just right to God only knows how many iterations. I also had to create a completely new caller 'TestPaginationCaller.pm' to get the tests to work.

    So here is the 25c story on how it works. I start with the normal two YAML files, one for content and one for tests. The differace is that I have both the 'request' and 'response' content and tests in each.

  • What is duck typing in Python?

    Python follows the EAFP (Easier to Ask Forgiveness than Permission) rather than the LBYL (Look Before You Leap) philosophy. The Python philosophy of EAFP is somewhat linked to its "duck typing" style of coding.

    When a programmer creates data in code, whether it's a constant or a variable, some programming languages need to know what "type" of data it is. For example, if you set a variable to 13, a computer doesn't know whether you mean for it to be used as a word ("thirteen") or as an integer (as in 13+12=25 or 13-1=12). This is why many languages require programmers to declare data before it's used.

  • Python 3: Process Command Line Arguments with argparse

    Python 3 provides a handy module, argparse, that makes it easy to get and parse command line arguments passed to your script.

    If you ever found argument parsing to be a tedious extra, then argparse might be just what you were looking for to simplify the process and focus on your code.

  • Git 2.27-rc0 Released - Still Working To Transition From SHA1 To SHA256

    Git 2.27-rc0 was released on Thursday as the first test release towards the next update on this leading version control system.

    With Git 2.27 development the transition continues in preparing the code-base in migrating from SHA1 to SHA256 hashes. Git for a number of releases has been working to move from SHA1 to SHA256 given the possibility of collisions for the former and thus potentially compromising security. Git 2.27-rc0 has seen more SHA256 preparations but isn't yet over (or near) the finish line.

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.
