  • Computers Use Processes, So Should You - LinuxInsider

    Pseudocode quality correlates with project quality. The key to good pseudocode is getting as granular as possible. This is called “decomposition.”

    To understand, let’s take a real-world example: if someone instructed you to cook a pot of spaghetti, you’d probably know what to do from past experience. When we think about it, however, this task is composed of about a dozen assumed steps. You need to get a packet of pasta, get a pot big enough for it, fill the pot with water…you get the idea.

    When composing pseudocode, you must break your process down into these small, seemingly obvious steps. That’s because you’re doing something new and complex instead of habitual and simple. Once you decompose your process into its smallest parts, your granularity is just right.

    There is a syntactic element that should be addressed, too.

    Each one of your atomic steps should have its own line. Also, make your conditional and looping steps stand out. Typically, this is done using indentation.

    For conditional statements, put the condition to be tested on the same level of indentation as the line above (unless it’s a loop or another conditional statement), and indent each step to be taken on satisfying that condition underneath it.

    For looping statements, put the condition under which the loop iterates on the same level of indentation as the line above (unless it’s a conditional statement or another loop), and indent each step to be executed per iteration underneath it.

  • Fun multipart/form-data inconsistencies

    I still remember the RFC number off the top of my head for the first multipart formdata spec that I implemented support for in curl. Added to curl in version 5.0, December 1998. RFC 1867.

    Multipart formdata is the name of the syntax for how HTTP clients send data in a HTTP POST when they want to send binary content and multiple fields. Perhaps the most common use case for users is when uploading a file or an image with a browser to a website. This is also what you fire off with curl’s -F command line option.

    RFC 1867 was published in November 1995 and it has subsequently been updated several times. The most recent incarnation for this spec is now known as RFC 7578, published in July 2015. Twenty years of history, experiences and minor adjustments. How do they affect us?

    I admit to having dozed off a little at the wheel and I hadn’t really paid attention to the little tweaks that slowly had been happening in the multipart formata world until Ryan Sleevi woke me up.

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.
