  • How to Install Apache Tomcat 10 in RHEL 9

    A web server is essential in the completion phases of a web application project. It lets users simulate, monitor, and assess the performance of their web application projects in a real-world environment. The choice and performance of such web servers sometimes depend on the main programming language used to create the project.

    Apache Tomcat is a fused implementation of Jakarta Expression Language, Jakarta Servlet, and WebSocket technologies. It is an ideal HTTP web server environment for pure Java coders. The Apache Software Foundation is responsible for Apache Tomcat’s development and maintenance.

    This article guide will walk us through the installation of an open-source java-based Apache Tomcat 10 web server on RHEL 9 Linux.

  • Manage your RPG players with pc | Enable Sysadmin

    For me, a good tabletop role-playing game (RPG), sometimes called a pen-and-paper RPG, is the perfect hobby for getting away from my computer. The classic editions of Dungeons & Dragons (D&D), for example, were released well before PDFs and eBooks existed, so I bring hardcover books and paper character sheets to my gaming table.

    In recent years, however, I've also started gaming online using Mumble voice chat. At first, I treated these games the same as my in-person games, but as more games started integrating online maps like Mythic Table, I found switching back and forth between keyboard-and-screen and pen-and-paper became a little frantic. When I'm running a player character (PC), most of what I need to refer to is on a character sheet, a document that lists my special abilities and powers. To get to that information quickly while managing a bunch of other applications, I use the pc command.

    The pc command parses RPG character sheets written in the INI format. It works with any RPG game system, as long as that system's character sheet data can be expressed as basic INI (most of them can be).

  • How to set per-creator/channel playback speed on YouTube

    You can find hundreds of browser extensions that let you fine-tune the playback speed for all YouTube videos. I’m happy with the default speed of 1× for most videos (and music). However, I want to speed up some channels without having to tweak the speed dial every time. Enter Samuel Li’s Speed Controller extension.

    I tend to fine-tune the playback speed to somewhere between 1,05× and 1,35×. By default, YouTube only lets you increase the playback speed by increments of 0,25×. This design decision has led to the creation of hundreds of extensions for fine-tuning and setting speeds other than the defaults.

  • How to Add Repository to Debian

    APT checks the health of all the packages, and dependencies of the package before installing it. APT fetches packages from one or more repositories. A repository (package source) is basically a network server. The term "package" refers to an individual file with a .deb extension that contains either all or part of an application. The normal installation comes with default repositories configured, but these contain only a few packages out of an ocean of free software available. In this tutorial, we learn how to add the package repository to Debian.

  • Making a Video of a Single Window

    I recently wanted to send someone a video of a program doing some interesting things in a single X11 window. Recording the whole desktop is easy (some readers may remember my post on Aeschylus which does just that) but it will include irrelevant (and possibly unwanted) parts of the screen, leading to unnecessarily large files. I couldn't immediately find a tool which did what I wanted on OpenBSD [1] but through a combination of xwininfo, FFmpeg, and hk I was able to put together exactly what I needed in short order. Even better, I was able to easily post-process the video to shrink its file size, speed it up, and contort it to the dimension requirements of various platforms. Here's a video straight out of the little script I put together: [...]

  • allow-new-zones in BIND 9.16 on CentOS 8 Stream under SELinux

    We run these training systems with SELinux enabled (I wouldn’t, but my colleague likes it :-), and that’s the reason I aborted the lab: I couldn’t tell students how to solve the cause other than by disabling SELinux entirely, but there wasn’t enough time for that.

  • Will the IndieWeb Ever Become Mainstream?

    This is an interesting question, thanks for asking it, Jeremy. I do have some history with the IndieWeb, and some opinions, so let’s dive in.

    The short answer to the question is a resounding no, and it all boils down to the fact that the IndieWeb is really complicated to implement, so it will only ever appeal to developers.

Open Hardware: XON/XOFF and Raspberry Pi Pico

  • From XON/XOFF to Forward Incremental Search

    In the olden days of computing, software flow control with control codes XON and XOFF was a necessary feature that dumb terminals needed to support. When a terminal received more data than it could display, there needed to be a way for the terminal to tell the remote host to pause sending more data. The control code 19 was chosen for this. The control code 17 was chosen to tell the remote host to resume transmission of data.
