  • Hans de Goede: Changing hidden/locked BIOS settings under Linux

    This all started with a Mele PCG09 before testing Linux on this I took a quick look under Windows and the device-manager there showed an exclamation mark next to a Realtek 8723BS bluetooth device, so BT did not work. Under Linux I quickly found out why, the device actually uses a Broadcom Wifi/BT chipset attached over SDIO/an UART for the Wifi resp. BT parts. The UART connected BT part was described in the ACPI tables with a HID (Hardware-ID) of "OBDA8723", not good.

    Now I could have easily fixed this with an extra initrd with DSDT-overrride but that did not feel right. There was an option in the BIOS which actually controls what HID gets advertised for the Wifi/BT named "WIFI" which was set to "RTL8723" which obviously is wrong, but that option was grayed out. So instead of going for the DSDT-override I really want to be able to change that BIOS option and set it to the right value. Some duckduckgo-ing found this blogpost on changing locked BIOS settings.

  • James Hunt: Can you handle an argument?

    This post explores some of the darker corners of command-line parsing that some may be unaware of.

    [...]

    No, I’m not questioning your debating skills, I’m referring to parsing command-lines!

    Parsing command-line option is something most programmers need to deal with at some point. Every language of note provides some sort of facility for handling command-line options. All a programmer needs to do is skim read the docs or grab the sample code, tweak to taste, et voila!

    But is it that simple? Do you really understand what is going on? I would suggest that most programmers really don’t think that much about it. Handling the parsing of command-line options is just something you bolt on to your codebase. And then you move onto the more interesting stuff. Yes, it really does tend to be that easy and everything just works… most of the time.

    Most? I hit an interesting issue recently which expanded in scope somewhat. It might raise an eyebrow for some or be a minor bomb-shell for others.

  • 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.
