  • Why self hosting is important

    Self hosting is about freedom, you can choose what server you want to run, which version, which features and which configuration you want. If you self host at home, You can also pick the hardware to match your needs (more Ram ? More Disk? RAID?).

    Self hosting is not a perfect solution, you have to buy the hardware, replace faulty components, do the system maintenance to keep the software part alive.

  • Apache's mod_wsgi and the Python 2 issue it creates

    If you use Apache (as we do) and have relatively casual WSGI-based applications (again, as we do), then Apache's mod_wsgi is often the easiest way to deploy your WSGI application. Speaking as a system administrator, it's quite appealing to not have to manage a separate configuration and a separate daemon (and I still get process separation and different UIDs). But at the moment there is a little problem, at least for people (like us) who use their Unix distribution's provided version of Apache and mod_wsgi rather than build your own. The problem is that any given build of mod_wsgi only supports one version of (C)Python.

  • Trouble with vnet and pf

    In the past, I have tried vnet jails with pf, and hit trouble. I was never able to get pf to allow the vnet traffic when having a default ‘block log all’ rule. More recently, I encountered the same problem when using byhve.

    This time, I moved byhve to another host, which is not using pf and I am writing this post to document the issue.

  • How to Boot Raspberry Pi 4 / 400 From a USB SSD or Flash Drive

    By default, Raspberry Pi boots up and stores all of its programs on a microSD memory card, which has a maximum theoretical bandwidth of 50 MBps on the Raspberry Pi 4 and just 25 MBps on prior models. In real-life, even the best microSD cards for Raspberry Pi get no faster than about 38 MBps in sequential writes. Using an external SSD as your main storage drive could speed things up significantly and, with a few commands and a simple firmware update, you can do just that.

    In our real-life tests of a Raspberry Pi 4 with SSD last year we got impressive performance with sequential transfer rates as high as 140 MB / 208 MBps for reading and writing. You can also use a standard USB flash drive, though we found the performance worse than a microSD card on many tasks.

  • How to Run Multiple Linux Commands in One Single Command

    If you use Linux daily, you will know that the command line is the most powerful tool when you working with files, installing and configuring system software, and running them. It becomes even more efficient if you run two or more commands at once on the command line and save a good deal of time.

  • How To Install Bluefish Editor on Linux Mint 20 - idroot

    In this tutorial, we will show you how to install Bluefish Editor on Linux Mint 20. For those of you who didn’t know, Bluefish is free and open-source software that provides numerous capabilities to the programmers for web development by supporting multiple languages such as Java, C/C++, Python, Go, and also a very large number of scripting languages.

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 Bluefish’s powerful editor on a Linux Mint 20 (Ulyana).

  • Check used disk space on Linux with du | Opensource.com

    No matter how much storage space you have, there's always the possibility for it to fill up. On most personal devices, drives get filled up with photos and videos and music, but on servers, it's not unusual for space to diminish due to data in user accounts and log files. Whether you're in charge of managing a multi-user system or just your own laptop, you can check in on disk usage with the du command.

  • 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.
