  • Ismael Olea: Congress/Conference organization tasks list draft

    Well, when checking my blog looking for references about resources related with conferences organization I’ve found I had any link to this thing I compiled two years ago (!!??). So this post is fixing it.

    After organizing a couple national and international conferences I compiled a set of tasks useful as an skeleton for you next conference. The list is not absolutely exhaustive neither strictly formal but it’s complete enough to be, I think, accurate and useful. In its current this task list is published at tree.taiga.io as Congress/Conference organization draft: «a simplified skeleton of a kanban project for the organization of conferences. It’s is specialized in technical and opensource activities based in real experience».

  • YABA is a Backplane Architecture Controller for Automation and IIoT (Crowdfunding)
  • DepthAI Brings AI plus Depth to the Raspberry Pi (Crowdfunding)

    Edge computing on the Raspberry PI has been a bit of ups and downs, especially with everyone gearing for AI in everything. 

  • This open-source AI tool quickly isolates the vocals in any song

    The software is called Spleeter and was developed by music streaming service Deezer for research purposes. Yesterday the company released it as an open-source package, putting the code up on Github for anyone to download and use. Just feed Spleeter an audio file and it spleets splits it into two, four, or five separate audio tracks known as stems. The results aren?t perfect but they are eminently usable and Spleeter itself is very fast. When running on a dedicated GPU it can split audio files into four stems 100 times faster than real time.

  • New LibreOffice packages for Slackware 14.2 and -current

    I uploaded the latest releases of LibreOffice for Slackware 14.2 and -current.

    On Slackware 14.2 you can enjoy the stable 6.2.8 version, this is the last release in the 6.2 series. For Slackware-current I went with the latest and greatest ‘fresh’ release of 6.3.3 which became available last week.

    Note that the packages for LibreOffice in my repository, do contain “libreoffice-kde-integration” for Slackware -current, containing Qt5 and KDE5 (aka Plasma5) support. On the other hand, packages for Slackware 14.2 do not contain “libreoffice-kde-integration” any longer.
    If you run Slackware-current but do not have KDE5 packages installed at all, don’t worry. LibreOffice will work great – the KDE integration package just will not add anything useful for you. On the other hand, if you have Plasma5 installed you will benefit from native file selection dialog windows and other integration features. And even if you do not have Plasma5 but you do have Qt5 installed, then you will be able to run LibreOffice with Qt5 User Interface elements instead of defaulting to GTK3.

  • Nolan Lawson shares what he has learned about accessibility

    Over the past year and a half, I have ventured time and again into the federated Mastodon social network. In those ventures, I have contributed bug reports to both the Mastodon client as well as some alternative clients on the web, iOS, and Android.

    One of those clients, a single-page, progressive web app, is Pinafore by Nolan Lawson. He had set out to create a fast, light-weight, and accessible, client from the ground up. When I started to use Pinafore, I immediately noticed that a lot of thought and effort had already gone into the client and I could immediately start using it.

  • Stop using ridiculously low DNS TTLs

                         

                           

    Of course, a service can switch to a new cloud provider, a new server, a new network, requiring clients to use up-to-date DNS records. And having reasonably low TTLs helps make the transition friction-free. However, no one moving to a new infrastructure is going to expect clients to use the new DNS records within 1 minute, 5 minutes or 15 minutes. Setting a minimum TTL of 40 minutes instead of 5 minutes is not going to prevent users from accessing the service.

                           

    However, it will drastically reduce latency, and improve privacy and reliability by avoid unneeded queries.

  • 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.
