A curated list of awesome honeypots, plus related components and much more, divided into categories such as Web, services, and others, with a focus on free and open source projects. There is no pre-established order of items in each category, the order is for contribution. If you want to contribute, please read the guide.
This is the second volume of Beej's Guide to C, the library reference.
This isn’t a tutorial, but rather is a comprehensive set of manual pages (or man pages as Unix hackers like to say) that define every function in the C Standard Library, complete with examples. There are, in fact, a number of functions left out of this guide, most notably all the optional “safe” functions (with a _s suffix). But everything you’re likely to want is definitely covered in here. With examples. Probably.
What we’ll try to do over the course of this guide is lead you from complete and utter sheer lost confusion on to the sort of enlightened bliss that can only be obtained through pure C programming. Right on.
In the old days, C was a simpler language. A good number of the features contained in this book and a lot of the features in the Library Reference volume didn’t exist when K&R wrote the famous second edition of their book in 1988. Nevertheless, the language remains small at its core, and I hope I’ve presented it here in a way that starts with that simple core and builds outward.
This guide assumes that you’ve already got some programming knowledge under your belt from another language, such as Python2, JavaScript3, Java4, Rust5, Go6, Swift7, etc. (Objective-C8 devs will have a particularly easy time of it!)
This textbook gives students an understanding of the most important topics in embedded systems design using a coherent, compelling and hands-on approach.

The yaff format has the following design aims:
Human-friendly. Truly human-readable and human-editable. For example, BDF and XML claim to be human-readable formats, but let's not kid ourselves. Human-friendly means plain text, flat, immediately visualised, easy on the eye, and light and obvious syntax. We should avoid duplication of information, unless it is of obvious use to a human user.
Able to represent fixed-width and proportional fonts.
Preserves comments, metadata and metrics. Formats such as BDF contain a wealth of metadata such as names, acknowledgements and style specification, but also font metrics that affect the way the font is displayed. The yaff format should preserve these.
Able to represent Unicode fonts as well as codepage fonts.
This repository contains bitmapped fonts from disused operating systems and graphical user interfaces.
As operating systems and GUIs have moved on to scalable vector fonts, the bitmap fonts that dominated the 1980s and 1990s languish away in non-obvious and often binary formats that are rapidly falling into obscurity.
The main purpose of this repository is to liberate these fonts from their binary shackles, preserving the ancient art of monochrome bitmap typography for human appreciation.
The fonts in this repository are stored in the human-friendly text-based YAFF format. As such, the easiest way to view them is to open the text files directly. Alternatively, you can use monobit to render them to images or convert them to font formats supported by current operating systems. You can also see the fonts as images here.
ReplayWeb.page provides a static site generated with MkDocs, an npm package/library, and an Electron app all in this repo.
This repository contains the 'frontend' UI for the replay system, while the 'backend' is provided via a service worker implementation found at: https://github.com/webrecorder/wabac.js. (Of course, both frontend and backend actually run in the browser). The frontend is loaded from ui.js, while the backend service/web worker is loaded from sw.js.
To run ReplayWeb.page and view web archives, a regular HTTP server is all that is needed.
pywb is a Python 3 web archiving toolkit for replaying web archives large and small as accurately as possible. The toolkit now also includes new features for creating high-fidelity web archives. This toolset forms the foundation of Webrecorder project, but also provides a generic web archiving toolkit that is used by other web archives, including the traditional "Wayback Machine" functionality.
So, basically, if you have WARC files you can view them with this application because it plays back the whole session.
A user.js configuration file for Mozilla Firefox designed to harden browser settings and make it more secure. This is a default template with every possible hardening measure enforced. See the relaxed branch for a variant providing more usability.
Limit the possibilities to track the user through web analytics. Harden the browser against known data disclosure or code execution vulnerabilities. Limit the browser from storing anything even remotely sensitive persistently. Make sure the browser doesn't reveal too much information to shoulder surfers. Harden the browser's encryption (cipher suites, protocols). Limit possibilities to uniquely identify the browser/device using browser fingerprinting. Hopefully limit the attack surface by disabling various features.
Search and Rescue drones are a life saving technology for disaster response, as they can provide real-time information, deliver supplies, and help locate survivors in inaccessible areas. Unfortunately, commercial SAR drones are often expensive and hard to repair.

Access to reliable and timely information about vulnerabilities affecting Information and Communication Technology (ICT) products and services contributes to an enhanced cybersecurity risk management. Sources of publicly available information about vulnerabilities are an important tool for users of these services, competent authorities, and the broader cybersecurity community. ENISA has established a European Vulnerability Database (EUVD) where entities, regardless of whether they fall within the scope of the NIS2 Directive, and their suppliers of network and information systems, as well as competent authorities, most notably CSIRTs, can voluntarily disclose and register publicly known vulnerabilities to allow users to take appropriate mitigating measures.
In line with Coordinated Vulnerability Disclosure practices, which aim at providing improved transparency regarding the publication process, the EUVD is eventually used to publicly disclose the vulnerability information.
To avoid efforts duplication and to support complementarity, ENISA closely cooperates with MITRE and European as well as non-European operators of the Common Vulnerabilities and Exposures (CVE) system. In this context, ENISA offers vulnerability registry services after its onboarding as a CVE Numbering Authority (CNA), with a focus on vulnerabilities in IT products discovered by or reported to European CSIRTs for coordinated disclosure.
I don't know if there's an RSS feed or an API yet.
The JPL Open Source Rover is an open source, build it yourself, scaled down version of the 6 wheel rover design that JPL uses to explore the surface of Mars. The Open Source Rover is designed entirely out of consumer off the shelf (COTS) parts. This project is intended to be a teaching and learning experience for those who want to get involved in mechanical engineering, software, electronics, robotics but is also an excellent research platform for rugged terrain. No prior skills or knowledge is required.
The OSR has been around since 2017 and has undergone many iterations. It is a premium and robust robot with a unique look, high customizability, and powerful abilities. The hardware and electronics were designed with expansions like a head display and robot arm in mind.
A curated list of awesome Model Context Protocol (MCP) servers. MCP is an open protocol that enables AI models to securely interact with local and remote resources through standardized server implementations. This list focuses on production-ready and experimental MCP servers that extend AI capabilities through file access, database connections, API integrations, and other contextual services.
