  • Day 18 – Santa and the Magic Tree (M-Tree) – Raku Advent Calendar

    It was Christmas Eve in the Workhouse and Santa was getting worried about how the weight of all those presents would reduce the height of his sled’s flighpath. Would he be able to clear the height of the tallest Christmas trees on his worldwide journey?

    He asked one of his helpers to whip up a quick script to see how much danger he would be in and in stepped p6elf to do the job.

    Naturally p6elf (pronounced “Physics Elf”) wanted to show off his raku skills to grow his reputation with Santa, the reindeer and all the other elves (knowing how much Santa is into the whole raku thing). So he started by picking up two modules and mixing them together. To share with the others so that they could see how they could easily make their own models so he used Brian Duggan’s cool Jupyter notebook module.

  • Generate Dynamical Passwords in a Linux terminal - TREND OCEANS

    The weakness of password management systems is a need to save passwords in a warehouse, which may be hacked. It would be hard to hack them if they were not kept in a warehouse.

    In this case, the weakness of modern password management systems will be removed. Therefore, we have the following problem: How to use and manage passwords without saving them in electronic or paper form?

  • Parse Arguments in Bash Scripts With getopts - OSTechNix

  • Detecting MISO and Opyn’s msg.value reuse vulnerability with Slither

    At the time of the report, I was finishing my blockchain security apprenticeship at Trail of Bits, where I learned more about Slither’s capabilities. I immediately wondered whether it was possible to create Slither detectors for these vulnerabilities. The answer is yes! Today, we are releasing two new open-source detectors that can detect the Opyn and MISO vulnerabilities, respectively: msg-value-loop and delegatecall-loop.

  • What does your code use, and is it vulnerable? It-depends!

    We are proud to announce the release of it-depends, an open-source tool for automatic enumeration of dependencies. You simply point it to a source code repository, and it will build a graph with the required dependencies. it-depends currently supports cargo, npm, pip, go, CMake, and autotools codebases, packages in their associated package managers, and Ubuntu apt.

  • 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.
