    Google Photos Takeout Helper

    Google Photos Takeout Helper

    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.

    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.

    TinyTeX releases

    TinyTeX releases

    Windows/macOS/Linux binaries and installation methods of TinyTeX

    A lightweight, cross-platform, portable, and easy-to-maintain LaTeX distribution based on TeX Live. TinyTeX is a custom LaTeX distribution based on TeX Live that is small in size but functions well in most cases, especially for R users. If you run into the problem of missing LaTeX packages, it should be super clear to you what you need to do (in fact, R users won’t need to do anything). You only install LaTeX packages you actually need. Currently, TinyTeX works best for R users. Other users can use it, too, it is just that missing LaTeX packages won’t be automatically installed, and you need to install them manually. Or you can go to the extreme to install all packages (see FAQ 3 for how), but remember there are thousands of them. Installing or running TinyTeX does not require admin privileges, which means you no longer need sudo or your IT. You can even run TinyTeX from a Flash drive.

    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.

    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.

    wkhtmltopdf

    wkhtmltopdf

    Convert HTML to PDF using Webkit (QtWebKit)

    wkhtmltopdf and wkhtmltoimage are open source (LGPLv3) command line tools to render HTML into PDF and various image formats using the Qt WebKit rendering engine. These run entirely "headless" and do not require a display or display service. There is also a C library, if you're into that kind of thing. The file pdf.h contains a fairly high level and stable pure c binding to wkhtmltopdf. These binding are well documented and do not depend on QT. Using this is the recommended way of interfacing with the PDF portion of libwkhtmltox. The rest of the headers directly exposes the C++ QT dependent class used internally by wkhtmltopdf and wkhtmltoimage. wkhtmltopdf is able to put several objects into the output file, an object is either a single webpage, a cover webpage or a table of contents. The objects are put into the output document in the order they are specified on the command line, options can be specified on a per object basis or in the global options area.
