Programming: rra-c-util, Javascript, Perl

  • rra-c-util 8.1

    rra-c-util is my collection of utility code that I use in my various other software packages (mostly, but not only, C).

    I now forget what I was reading, but someone on-line made a side reference to formatting code with clang-format, which is how I discovered that it exists. I have become a big fan of automated code reformatting, mostly via very positive experiences with Python's black and Rust's rustfmt. (I also use perltidy for my Perl code, but I'm not as fond of it; it's a little too aggressive and it changes how it formats code from version to version.) They never format things in quite the way that I want, but some amount of inelegant formatting is worth it for not having to think about or manually fix code formatting or argue with someone else about it.

  • Updating a Persistent Window from Javascript Part 1: postMessage

    I'm trying to update my htmlpreso HTML presentation slide system to allow for a separate notes window.

    Up to now, I've just used display mirroring. I connect to the projector at 1024x768, and whatever is on the first (topmost/leftmost) 1024x768 pixels of my laptop screen shows on the projector. Since my laptop screen is wider than 1024 pixels, I can put notes to myself to the right of the slide, and I'll see them but the audience won't.

    That works fine, but I'd like to be able to make the screens completely separate, so I can fiddle around with other things while still displaying a slide on the projector. But since my slides are in HTML, and I still want my presenter notes, that requires putting the notes in a separate window, instead of just to the right of each slide.

    The notes for each slide are in a <div id="notes"> on each page. So all I have to do is pop up another browser window and mirror whatever is in that div to the new window, right? Sure ... except this is JavaScript, so nothing is simple. Every little thing is going to be multiple days of hair-tearing frustration, and this was no exception.

    I should warn you up front that I eventually found a much simpler way of doing this. I'm documenting this method anyway because it seems useful to be able to communicate between two windows, but if you just want a simple solution for the "pop up notes in another window" problem, stay tuned for Part 2.

    So I was quickly knocking off the various S3Control actions until I ran in to 'ListJOBS' which I though would be an easy one as there is no XML content on this call.

  • 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.
