  • An Introduction to Go

    (What follows is an excerpt from my master’s thesis, almost all of section 2.1, quickly introducing Go to people familiar with CS)

    Go is an imperative programming language for concurrent programming created at and mainly developed by Google, initially mostly by Robert Griesemer, Rob Pike, and Ken Thompson. Design of the language started in 2007, and an initial version was released in 2009; with the first stable version, 1.0 released in 2012 1.

    Go has a C-like syntax (without a preprocessor), garbage collection, and, like its predecessors devloped at Bell Labs – Newsqueak (Rob Pike), Alef (Phil Winterbottom), and Inferno (Pike, Ritchie, et al.) – provides built-in support for concurrency using so-called goroutines and channels, a form of co-routines, based on the idea of Hoare’s ‘Communicating Sequential Processes’ 2.

    Go programs are organised in packages. A package is essentially a directory containing Go files.

  • Python Insider: Python 3.7.2 and 3.6.8 are now available

    Python 3.7.2 and 3.6.8 are now available. Python 3.7.2 is the next maintenance release of Python 3.7, the latest feature release of Python.

  • Using a Kotlin-based gRPC API with Envoy proxy for server-side load balancing

    These days, microservices-based architectures are being implemented almost everywhere. One business function could be using a few microservices that generate lots of network traffic in the form of messages being passed around. If we can make the way we pass messages more efficient by having a smaller message size, we could the same infrastructure to handle higher loads.

    Protobuf (short for “protocol buffers”) provides language- and platform-neutral mechanisms for serializing structured data for use in communications protocols, data storage, and more. gRPC is a modern, open source remote procedure call (RPC) framework that can run anywhere. Together, they provide an efficient message format that is automatically compressed and provides first-class support for complex data structures among other benefits (unlike JSON).

  • Intro to the Python Random Module

    Even for someone not interested in computer programming, the usefulness of generating random numbers in certain circumstances is something obvious. In most board games we throw dice to generate an unpredictable number that defines the player's next move. Also, we can all agree that playing any card game would be pointless without a proper shuffle between rounds.

    But random numbers are not only important in relatively trivial fields like entertainment or gambling. They're especially crucial in the field of cryptography. In order to ensure safe transmission of data, every time a secure connection is necessary, a random key has to be generated. Many different kinds of electronic communication use this kind of security. It's very important for the key to be difficult to guess - the best way to ensure that is by making it random since the moment someone guesses the key, they are able to decipher the message - and the communication is not secure anymore.

  • 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.
