  • Review: GAOMON M10K 2018 Graphic Tablet on Linux for Digital Painting.

    I haven't put that in the video, because it is a bit long and backstage. But I'm happy to share it on the blog:

    Around 2018, the brand Gaomon contacted me by email for a review. But at that time they only had a driver for Windows and Mac, so I rejected their proposal because −as you know− I'm using only a GNU/Linux operating system for my art since more than ten years.

    Rejecting brands this way is something I do very often. Not daily, but easily on a monthly basis. I probably got already all existing brands of tablets reaching my mailbox thanks to the good statistic on the channel.

    A parenthesis about that: I also met a large amount of hardware sellers totally unrelated to digital art or FLOSS who pretends to like my channel, saw all my videos (be fans?). Then they offer only a Win/Mac product in a email template, or worst: a gadget totally unrelated to digital art. (a lamp for monitor! a sound system, a gamepad? etc...) Poeple working in marketing department should probably stop considering their recipient as idiots. I mean: it's ok to sell products and propose hardware for review. But pretending to saw all videos and be fans only to flatter the ego of creators... Without having a check on the channel and content... This is the type of marketing talk I'm really deeply allergic. Parenthesis closed.

    Anyway, in all situation, I try to optimize the new contact with a minimum of FLOSS advocacy. I reply politely with a speech about why they should get a Free/Libre driver, why I'll be happy to review if the hardware works on GNU/Linux and get in the scope of my passion for digital-art or comic. I'll not lie, I often get no replies, or replies that try to convince me to do the review on Win/Mac (lol).

    But, In the case of Gaomon, something happened after this first ping-pong of usual proposal on one side and advocacy on my side. In fact, the marketing employee at Gaomon pushed my request to their R&D department (research and development). And so: they started to cooperate with the Digimend project on a Free/Libre Linux driver.

  • How to install MongoDB Server on Alpine Linux - Linux Shout

    Alpine Linux is a Linux distribution optimized for resource efficiency and security. It can be installed in different versions and can therefore run completely from the RAM, for example. In addition to the latest x86 hardware, images are also available for the various Raspberry Pi models. This Linux distribution is based on musl and BusyBox and uses OpenRC for its init system and compiles all user-space binaries as position. Hence, that’s the reason users prefer it for running containers, especially Dockers.

    It is an extremely lightweight Linux operating system that aims at minimalism and high security. The standard Alpine ISO size is around 138 MB only, hence quite easy to move, if required. This makes Alpine fits comfortably on a CD-R with enough space. Alpine Linux uses a technique called location-independent executables this prevents attackers to exploit any flaw in the memory because this feature randomly locates programs in memory.

  • 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.
