  • This Self Taught Programmer Solved MIT’s 20-Yr-Old Cryptographic Puzzle

    A Belgian self-taught programmer has solved MIT’s 20-year-old cryptographic puzzle designed by Ron Rivest who is one of the pioneers in RSA cryptographic protocol and, in fact, the R in RSA was taken from his name.

    In 1999, a time capsule with a puzzle designed by Rivest was delivered to the famous architect Frank Gehry to design MIT’s Computer Science and Artificial Intelligence Lab, which is now known as CSAIL. The time capsule consisted of 50 rare items contributed by the likes of internet founder Sir Tim Berners Lee and Microsoft founder Bill Gates.

  • What is a developer journal?

    One of the best parts of working in computer science is that our jobs center on solving problems. While many of us joke that continually struggling to figure things out is frustrating, we do it because there is nothing quite like that feeling of finding a solution. Then, of course, the momentary euphoria ends, and we move onto the next problem.

    The hope is that our solution is another data point that propels us towards becoming a more accomplished and effective engineer. But what about all the times we encounter an old problem, one we've already solved, and cannot remember where we found that one, tiny piece of information that allowed us to fix it? Being an engineer can often feel a bit like you're living through Groundhog Day, always in a place where you know you've solved something sort of kind of like this before. My solution to this is a developer journal.

  • Four graphic interfaces for Git

    Complex Git projects sometimes require a better view of the dependencies and branches. Several tools offer GUI options for Git. We take a look at gitk, gitg, git-gui, and GitAhead.

    Graphical User interfaces (GUIs) for the Git version control system let users visualize branches and different version levels. Developers thus have a better overview of their projects' status. In addition, GUIs make Git easier to use, because programmers do not need to remember any of the cryptic Git commands.

  • Tips from the experts on getting more from Git

    The Git distributed version control system is a popular tool for managing open source development projects. If you know the basics of Git but are looking to learn the ways of the experts, read on for some useful Git tips and tricks.

    "You must know a few Git experts," an editor at Linux Magazine said to me. As the leader of the SUSE documentation team, I spend large portions of my day around veteran Linux developers. When I agreed to ask the team for some tips for using the Git version control system [1], I did not expect that I would trigger a thread that lasted several days (Figure 1).

  • 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.
