You can read the book as Markdown files, or download the PDFs (probably easier).
Multiple languages: German, English, Spanish, French, Hindi, Portuguese
Two major collections of hobbyist and constructor's books from the UK. There are freely downloadable PDFs of all kinds of radio and electronics related stuff here.
The free, open source Python module markdown-pdf will create a PDF file from your content in markdown format. UTF-8 enabled. Can embed images. Supports pagination and tables of contents. Supports CSS for styling.
Only a module, though, not a CLI tool.
Convert Markdown files to PDF with styles. Supports the use of CSS for styling. Can be used as a CLI tool or a Python library.
Percollate is a command-line tool that turns web pages into beautifully formatted PDF, EPUB, HTML or Markdown files.
A python LLM chat app using Django Async and LLAMA2, that allows you to chat with multiple pdf documents. Components are chosen so everything can be self-hosted.
Project uses LLAMA2 hosted via replicate - however, you can self-host your own LLAMA2 instance.
Downloadable templates for making lockpicks (conventional as well as specialized). Links to templates for other kinds of lock tools.
The original "collection of pick templates" threads on lockpicking101.com are littered with dead links and annoying photobucket .webps that are blurred unless you have an account. HUGE credit goes to the users of LP101. I'm favoring the PDF conversions so you can be sure that they print 1:1. While I was at it, I went ahead and collected every pick template image and PDF that I could find anywhere on the internet. If you want the other 350 MB of blurry, skewed photos of picks next to rulers, then just contact me.
An HTML page with Javascript that edits and arranges PDFs into printable zine layouts.
Supports the following zine formats:
With options for:
The unstructured library provides open-source components for ingesting and pre-processing images and text documents, such as PDFs, HTML, Word docs, and many more. The use cases of unstructured revolve around streamlining and optimizing the data processing workflow for LLMs. unstructured modular functions and connectors form a cohesive system that simplifies data ingestion and pre-processing, making it adaptable to different platforms and efficient in transforming unstructured data into structured outputs.
There is also an API built around this module.
What is this? Well, it’s a guide to a bunch of concepts that you might see in networking. It’s not Network Programming in C—see Beej’s Guide to Network Programming1 for that. But it is here to help make sense of the terminology, and also to do a bit of network programming in Python.
Is it Beej’s Guide to Network Programming in Python? Well, kinda, actually. The C book is more about how C’s (well, Unix’s) network API works. And this book is more about the concepts underlying it, using Python as a vehicle.
Good and Cheap is a cookbook for people with very tight budgets, particularly those on SNAP/Food Stamps benefits. The PDF is free to download (ahora en Español!) (you really don't need to sign up for her newsletter, just click one of the buttons) and has been downloaded more than 15,000,000 times. It is also available in print, and for every copy sold we donate one to someone who can’t afford it.
To escape a deluge of generated content, companies are screening your resumes and documents using AI. This website allows you to inject invisible text into your PDF that will make any AI language model think you are the perfect candidate for the job.
When you select a PDF file, the text in the textbox is inserted on the first page of the document. The text is rendered with minimum font size and opacity, so it is invisible to the human eye. However, it is still visible to AI text recognition algorithms.
This project seeks to provide "travel advice" for trans travelers (and our companions) based on laws and practical safety within various jurisdictions.
It is not geared towards people already living in a jurisdiction. For instance, laws about medical insurance won't generally be mentioned, as most people traveling will have out-of-jurisdiction medical insurance. Likewise, laws about school athletics will not be mentioned as these generally don't impact travelers. However, information that might impact travelers in different situation will be mentioned. For instance, someone assigned to a business project for several months in a state may need to utilize medical care. Others may travel with children and be concerned about how this could be seen as child abuse or cause child custody issues.
This is also available as a PDF. This may be particularly useful to people needing to cite this information or who want to carry a copy with them on their mobile device. You can access the PDF version at https://TravelWhileTrans.com/output/trans-travel.pdf
Stone Butch Blues, Leslie Feinberg’s 1993 first novel, is widely considered in and outside the U.S. to be a groundbreaking work about the complexities of gender. Feinberg was the first theorist to advance a Marxist concept of “transgender liberation.” Sold by the hundreds of thousands of copies and also passed from hand-to-hand inside prisons, Stone Butch Blues has been translated into Chinese, Dutch, German, Italian, Slovenian, Turkish, and Hebrew (with hir earnings from that edition going to ASWAT Palestinian Gay Women). The novel was winner of the 1994 American Library Association Stonewall Book Award and a 1994 Lambda Literary Award.
The 20th Anniversary Author’s Edition of Stone Butch Blues is available in multiple formats. A free PDF can be downloaded from this site, and a hardcopy PoD version can be purchased from Lulu.
The Transactor was started life in 1978 as a Commodore Business Machines publication used to explain low level details of the Commodore PET. In 1982 it was reborn as a bimonthly independent magazine published out of Milton Ontario (Toronto) covering all 8bit Commodore’s. This revised magazine used the slogan new slogan was “The Tech News Journal for Commodore Computers” and was paid for through advertising and subscription prices. A quick scan of the covers below and you will be able to see when this change occurred. The Commodore Transactors were mass produced using a very inexpensive mimeograph technology while the independent magazine was created using a proper printing press.
Both publications were known for their depth. They covered hardware hacking in detail and were read by serious users. One issue even boasted that it was 95% advertising free right on the cover.
pdfcpu is a PDF processing library written in Go supporting encryption. It provides both an API and a CLI. Supported are all versions up to PDF 1.7 (ISO-32000).

This self-guided course gives numeric examples of the basic calculations that a slide rule can do. Just follow the step-by-step instructions and you will be amazed by the power and versatility of the venerable Slipstick. Click on any of the images below to get a large, unmarked, blowup of each slide rule as shown in the problem.
The site can also be downloaded as a PDF for use as a textbook.
The Pinouts Book is a free digital book created for designers and engineers as a quick reference for remembering the different pinout functions in your electronics projects.
The book covers 130 commonly used components (view list), such as connectors, single board computers, dev boards, memory cards, microcontroller chips, and more.
If you need more technical information, each page has a link at the top (e.g. pinouts.org/XXX), and these redirect to official datasheets / specifications.
We’re going to be updating the book as time goes on, and we hope you find it useful.
pText is a pure python library to read, write and manipulate PDF documents. It represents a PDF document as a JSON-like datastructure of nested lists, dictionaries and primitives. Extract and edit metadata, extract and edit text and images, add annotations.
Seems like it would be useful for a large-scale indexing effort.
