Programming: Git, Secure Coding, CMake and Perl

  • Self-hosting a tiny git remote

    There are plenty of full-featured git forges out there. If you’re a software developer, you’ve probably used GitHub, Bitbucket, and GitLab at some point – and you’re maybe familiar with Gitea, Gogs, or SourceHut.

    All of this software is great, and each git forge has valuable features that save users time and effort when working on projects.

    Sometimes, though, all I need is a simple git remote to sync a simple project. I don’t need issue trackers, wikis, continuous integration, or a way to manage patches coming from multiple contributors.

    For these use cases, I have set up a tiny git remote that only I can access.

  • Secure by Design

    Secure by Design is quite a practical book, with many ideas that can be used right away. It shows concrete ways of coding that improve security by limiting the ways in which bugs can slip in. There are quite a few code examples that help explaining the concepts. Sometimes the book is too wordy, such as the example in chapter 11, where insurance policies where issued without payment. But overall it is great resource for developers that want to write more secure code.

  • How We Fixed One Bug in CMake

    In August 2019, CMake introduced the long-awaited support for precompiled headers. Before that, one had to use different plugins, for example, Cotire. Right after the release of CMake with new functionality, there were several more improvements. But in the fall, we decided that we could already start using this feature, and rewrote our scripts. Later, we found a bug that generated incorrect parameters of the Clang compiler and prevented the launch of the PVS-Studio analyzer. The bug had to be fixed by ourselves.

  • The [Perl] Weekly Challenge #052

    I look forward to the weekly challenges only to learn something new in Raku. I would like to thank many people (unfair to name few here) who guided me every time I am stuck, thanks to the Gang at Twitter.

    As the pattern I always follow, I started with Perl solution. I would not waste any time explaining my code as it is self explanatory.

  • Comparing coronavirus SARS-CoV-2 spike protein sequences with BioPerl

    Continuing from extraction of coronavirus spike protein sequences I decided to compare them and see if any mutations could be found. To do this I needed to align sequences to each other and get multiple sequence alignment. There are many tools that might be used and I have chosen MUSCLE as it is fast, easy to use and accurate enough. However, other tools such as MAFFT or T-Coffee should also work well and could give more accurate alignments in more complicated cases than the one I was dealing with.

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.
