  • State of Native Big File Handling in Git

    After many struggles with using git LFS on repositories that need to store big files, I decided to spend some time on checking the status of the built-in partial clone functionality that could possibly let you achieve the same (as of git 2.30).

  • Excellent Free Tutorials to Learn V

    V is a statically typed compiled programming language designed for building maintainable software. It’s similar to Go and its design has also been influenced by Oberon, Rust, Swift, Kotlin, and Python.

    It compiles itself in less than one second with zero library dependencies.

  • Debugging on Valgrind: Adding fused-multiply-add support for the AArch64 processor

    Valgrind is a great tool not only for finding errors related to memory management in a program, but also for memory consumption analysis, performance profiling, issues related to multithreading, and more. In this article, I introduce Valgrind's undocumented --trace-flags option and explain how we improved Valgrind's accuracy in one area related to the AArch64 processor from Arm.

  • A strong commitment to backwards compatibility means keeping your mistakes

    Plenty of people like backwards compatibility, especially strong backwards compatibility. But it has what is a sometimes unpleasant consequence, which is that a strong commitment to backwards compatibility requires keeping your mistakes. Or at least many of them. To put it one way, you need to keep mistakes that work, and of course you have to keep them giving the same result as they currently do. For example if you provide an API that people can use to express potentially conflicting things and you don't reject the attempt but instead give some deterministic result, you're stuck with it.

  • Matching nothing

  • 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.
