    keycloak-config-cli

    Import YAML/JSON-formatted configuration files into Keycloak

    keycloak-config-cli is a Keycloak utility to ensure the desired configuration state for a realm based on a JSON/YAML file. The format of the JSON/YAML file is based on the export realm format. Store and handle the configuration files inside git just like normal code. A Keycloak restart isn't required to apply the configuration. The config files are based on the keycloak export files. You can use them to re-import your settings. But keep your files as small as possible. Remove all UUIDs and all stuff that is default set by keycloak.

    Pandoc

    Pandoc

    The universal markup converter

    Pandoc is a universal document converter able to convert files from a multitude of markup formats into another. With Pandoc, you have a swiss-army knife of a converter, able to convert practically any markup format into any other. Pandoc contains a Haskell library for conversions as well as a command-line tool that uses this library. It can convert to and from just about anything-- lightweight markup formats, HTML formats, documentation formats, ebooks, TeX formats, word processor formats and so much more. It understands several useful markdown syntax extensions, such as document metadata, footnotes, tables, and more. If you want strict markdown compatibility however, these extensions can be turned off. Pandoc is no doubt powerful and customizable, but it is important to note that its intermediate representation of a document is less expressive than many of the formats, so it may not produce perfect conversions every time.

    Script that organizes the Google Takeout archive

    If you ever want to move from Google Photos to another platform/solution, your fastest choice to export all photos is Google Takeout. But when you download it, you will find yourself with zips with hundreds of little folders with weird .json files inside. What if you want to just have one folder with all photos, in chronological order? Good luck copying all of that.

    BentoPDF

    BentoPDF

    A Privacy First PDF Toolkit

    BentoPDF is a self-hosted, open-source PDF toolkit that provides a suite of local PDF manipulation features for users who want full control over their documents without relying on cloud PDF services. It offers functionality to merge, split, compress, rotate, and convert PDFs through an easy-to-deploy container or local installation, making it ideal for individuals and teams that handle large volumes of PDF files regularly. Because it runs entirely on your own system or server, BentoPDF helps ensure that sensitive documents never leave your environment — a critical consideration for privacy-conscious users or organizations with strict data policies. Its design aims to balance robust feature coverage with a simple setup process, typically involving a Docker image so you can start using the toolkit with minimal configuration. BentoPDF also supports automation via command line parameters or API calls, so it can be integrated into batch workflows or document pipelines.

    geckodriver

    geckodriver

    WebDriver for Firefox

    geckodriver is an implementation of WebDriver, and WebDriver can be used for widely different purposes. How you invoke geckodriver largely depends on your use case. If you are using geckodriver through Selenium, you must ensure that you have version 3.11 or greater. Because geckodriver implements the W3C WebDriver standard and not the same Selenium wire protocol older drivers are using, you may experience incompatibilities and migration problems when making the switch from FirefoxDriver to geckodriver. Generally speaking, Selenium 3 enabled geckodriver as the default WebDriver implementation for Firefox. With the release of Firefox 47, FirefoxDriver had to be discontinued for its lack of support for the new multi-processing architecture in Gecko. Since geckodriver is a separate HTTP server that is a complete remote end implementation of WebDriver, it is possible to avoid using the Selenium remote server if you have no requirements to distribute processes across a matrix of systems.

    Better BibTeX for Zotero

    Better BibTeX for Zotero

    Make Zotero effective for us LaTeX holdouts

    Better BibTeX (BBT) is a plugin for Zotero and Juris-M that makes it easier to manage bibliographic data, especially for people authoring documents using text-based toolchains (e.g. based on LaTeX / Markdown). Zotero does all its work in UTF-8 Unicode, which is absolutely the right thing to do. Unfortunately, for those shackled to BibTeX and who cannot (yet) move to BibLaTeX, unicode is a major PITA. Also, Zotero supports some simple HTML markup in your items that Bib(La)TeX won’t understand.

    mPDF

    mPDF

    PHP library generating PDF files from UTF-8 encoded HTML

    mPDF is a PHP library that generates PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files ‘on-the-fly’ from his website, handling different languages. It is slower than the original scripts e.g. HTML2FPDF and produces larger files when using Unicode fonts, but support for CSS styles etc. and has been much enhanced. Supports almost all languages including RTL (Arabic and Hebrew), and CJK (Chinese-Japanese-Korean). Nested block-level elements (e.g. P, DIV) including margins, borders, padding, line height, background colors, etc. Right-to-left languages are supported, with automatic detection of RTL characters within a document. Transposes tables, lists, text justification, and table cell alignment, as well as a full-text reversal for RTL characters. Automatically detects non-RTL characters and displays these in the original order.
