Programming: Raspberry Pi 4, NVIDIA Jetson, GCC, Perl and Python

  • Raspberry Pi 4 Complete Guide

    I've been a fan of Raspberry Pi since the original Pi 1 so it's always exciting for me to see how these boards evolve with each new model. The newest Raspberry Pi 4 is no exception and it certainly raises the bar for Single Board Computers.

    While the older models were mostly only useful as educational boards or for DIY/maker projects, the Pi 4 finally packs a real punch in terms of performance. With a 64-bit quad core ARM processor and up to 4GB of ram, I expect these boards to end up in all kinds of applications, ranging from home media centers to actual home desktop use.

  • GCC 11 Enables Co-Routines Support In C++20 Mode

    Now that GCC 10 is out the door, the C++ coroutines functionality is being enabled by default when running in C++20 mode (std=c++20). Thus for next year's GCC 11 release will be working coroutines functionality when C++20 is enabled. And by then the remaining bits of C++20 support in the GNU Compiler Collection should also be ironed out.

  • The Weekly Challenge #060

    I am not sure about you guys but I found writing blog is very nice feeling. I get nice ideas to clean up the code. This week, I even found a bug that even unit test couldn’t catch. I would rather not share it, quite embarassing. The bug was in my Perl solutions to the “Find Numbers” task. My git commit tree might disclose it, if you really want to know.

    Back to the weekly challenges, I liked both tasks and I finished the Perl solutions to both task on day one i.e.Monday itself. Generally I go slow on Monday and Tuesday to recover from the weekend hangover, the most busiest time of the week because of Perl Weekly Challenge and Perl Weekly Newsletter. When I am editing the Perl Weekly Newsletter then it is double whammy for me. I am glad that I only edit alternate week. So I get a breather in between.

    Once I am done with Perl solutions, I find myself little relax as I know I can easily get the Raku version quickly. Because of my fasting, I find it hard to do any coding during the day. After breaking the fast, I feel sleepy and take quick couple of hours of nap break. I then wake up midnight to perform night prayer and eat the Sehar. It is the time after morning prayer, I find myself full of energy. On saturday morning after prayer at 3:20 am, I started preparing the ground for Raku solutions. By 10:00 am, I had both the tasks done. Not a bad attempt. I did throw few questions when I was struck at one point. I will talk about it in detail later.

    Since I started working from home, my daily routine has gone upside down. During the Ramadan, my office working hours is 8:00 am to 3:30 pm without lunch break, obviously. From 3:30 pm to 8:50 pm (time of breaking fast), is for me to perform regular prayer and relax. Sometimes I watch movie on Netflix. Couple of days ago, I watched 6 Days, nice movie. Before that I watched Bodyguard. I am new to Netflix and therefore most of the movies are new to me.

  • 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.
