  • Resurrecting my Iomega Zip 100 parallel-port drive – Linux comes to the rescue

    Back in 1998 I purchased what was then a state-of-the-art storage medium: an external Iomega Zip 100 drive, which used removable 100 MB ‘SuperFloppy’ disks. Until 2002 I backed up my important files on removable Zip 100 MB disks. Over several years in the 1990s Iomega released various models of the Zip 100 GB drive: internal SCSI; internal IDE; internal ATAPI; external DB-25 IEEE 1284 parallel port; external USB 1.1. I bought the external DB-25 IEEE 1284 parallel port, model Z100P2. When affordable CD drives and external hard disk drives started to appear I began using those for backups instead, and the Zip drive and a box full of Zip 100 MB disks had been gathering dust on a shelf at home since I stopped using them in 2002.

  • PiMod Zero for Raspberry Pi Zero SBC broadcasts video to your older NTSC TV (Crowdfunding) - CNX Software

    Playing retro games or watching older movies on your Raspberry Pi Zero board over a modern digital video interface like HDMI clearly ruins the experience! While it should be possible to use to 2-pin reserved for video composite on the Raspberry Pi Zero to connect to an old TV, PiMod Zero HAT allows you to get back that retro feeling even with TVs lacking RCA composite and audio inputs by broadcasting video over VHF to older NTSC compatible televisions.

  • The missing ps2pdf mystery

    Posting here as a placemarker, putting down the thoughts so far. Will append to this post if/when solved.
    Feodor reported that /usr/lib/cups/backend/pdf-writer wants /usr/bin/ps2pdf, which is missing.
    'pdf-writer' is a script, and I had to hunt where that came from. It is in PET package 'cups_pdf'. This is an ancient PET, for printing a Postscript or PDF to file. But the GTK print dialog offers "Print to file" as well, so 'cups_pdf' is redundant, so have removed that PET.
    I looked at packages.debian.org and found that 'ps2pdf' is part of the 'ghostscript' package. Interesting, my ghostscript, compiled in OE, doesn't have it.

  • Kubernetes: Introducing Indexed Jobs

    Once you have containerized a non-parallel Job, it is quite easy to get it up and running on Kubernetes without modifications to the binary. In most cases, when running parallel distributed Jobs, you had to set a separate system to partition the work among the workers. For example, you could set up a task queue to assign one work item to each Pod or multiple items to each Pod until the queue is emptied.

  • 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.
