  • Blast Radius

    This is a remarkable argument for infrastructure based on open source software, but that isn't what this post is about. Below the fold is a meditation on the concept of "blast radius", the architectural dilemma it poses, and its relevance to recent outages and compromises.

  • Raspberry Pi makes LEGO minifigures play their own music
  • Inkplate done quick

    I recently received an Inkplate, and while I’m in the middle of a few interesting projects already, I couldn’t let it sit there unused. Until I get a longer chunk of time to turn it into something really nifty — maybe an embedded debugging helper of some kind — it can at least mean I no longer need to have Mail.app open.

  • The 20th Annual Workshop on the Economics of Information Security (WEIS 2021)

    The Workshop on the Economics of Information Security (WEIS) is the leading forum for interdisciplinary scholarship on information security and privacy, combining expertise from the fields of economics, social science, business, law, policy, and computer science. Prior workshops have explored the role of incentives between attackers and defenders of information systems, identified market failures surrounding internet security, quantified risks of personal data disclosure, and assessed investments in cyber-defense. The 2021 workshop will build on past efforts using empirical and analytic tools not only to understand threats, but also to strengthen security and privacy through novel evaluations of available solutions.

  • A look at GSM

    There are well documented security flaws in GSM, and publicly available tools to exploit them. At the same time, it has become considerably cheaper and easier to analyze GSM traffic over the past few years. Open source tools such as gr-gsm have matured, and the community has developed methods for capturing the GSM spectrum without the need for expensive SDR radios.

    With less than $100 and a weekend it’s possible to capture and analyze GSM traffic. With some extra effort it’s possible to decrypt your own traffic, and depending on how your mobile provider has set up their network it may even be possible for somebody else to illegally decrypt traffic they don’t own.

    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.
