Show HN: A ninja's Handbook: A book on privacy, security, and anonymity online
This book was a project that I started after two years of constant paranoia and anxiety, trying to achieve a decent level of privacy and anonymity. From the things I learned during that time, I decided to write a book to help jump-start the privacy and anonymity journey of those who might be in the same situation.<p>I know this book is not a complete guide on how to harden your devices and operating systems, and it wasn't meant to be. It was supposed to cover the very fundamentals of privacy, security, and anonymity rather than the highly technical stuff that might exhaust and frustrate normies.<p>Repo: <a href="https://github.com/zolagonano/a-ninjas-handbook">https://github.com/zolagonano/a-ninjas-handbook</a>

Show HN: Learn Blender shortcuts with lots of tiny videos
I've used blender for more than a decade and now ask myself what the best way to teach it would look like.<p>Video generally seems the best format to explain how to solve a specific problem, but its not exactly great for larger collections of small bits of information – like blender shortcuts.<p>This is why I made this video/text hybrid website from scratch. If you're a blender user or have experience in teaching others, I'd be very happy to hear your thoughts on it.<p>I'm also posting this here because I assume many of your are professional web developers. I'm a learning hobbyist and wondering if there are any issues with the way I built the website.<p>Thanks!<p>Github: <a href="https://github.com/hollisbrown/blendershortcuts">https://github.com/hollisbrown/blendershortcuts</a>

Show HN: Wikipedia Browser a La Andy Matuschak's Evergreen Notes
I was inspired by Andy Matuschak's Evergreen Notes viewer and created this small web app to browse Wikipedia in the same way. Clicking on a link opens the content in a new pane to the right. And you can resize panes. It's really nice for following rabbit holes or checking out lists from articles. Let me know what you think!<p>Code here: <a href="https://github.com/steezeburger/wikipedia-browser">https://github.com/steezeburger/wikipedia-browser</a>

Show HN: COBOL-REKT, a toolkit for analysing and reverse-engineering COBOL
This is an evolving toolkit of capabilities helpful for analysing and reverse engineering legacy Cobol code. Currently, the following capabilities are available:<p>- Program / Section-level flowchart generation based on AST (SVG or PNG)
- Parse Tree generation (with export to JSON)
- Control Flow Tree generation (with export to JSON)
- Allows embedding code comments as comment nodes in the graph
- The SMOJOL Interpreter (WIP)
- Injecting AST and Control Flow into Neo4J
- Injecting Cobol data layouts from Data Division into Neo4J (with dependencies like MOVE, COMPUTE, etc.) + export to JSON
- Injecting execution traces from the SMOJOL interpreter into Neo4J
- Integration with OpenAI GPT to summarise nodes using bottom-up node traversal (AST nodes or Data Structure nodes)
- Exposes a unified model (AST, CFG, Data Structures with appropriate interconnections) which can be analysed through [JGraphT](<a href="https://jgrapht.org/" rel="nofollow">https://jgrapht.org/</a>), together with export to GraphML format and JSON.
- Support for namespaces to allow unique addressing of (possibly same) graphs
- ALPHA: Support for building Glossary of Variables from data structures using LLMs
- ALPHA: Support for extracting Capability Graph from paragraphs of a program using LLMs
- ALPHA: Injecting inter-program dependencies into Neo4J (with export to JSON)
- ALPHA: Paragraph similarity map<p>Contributions / use cases are welcome!

Show HN: Denormalized – Embeddable Stream Processing in Rust and DataFusion
tl;dr we built an embeddable stream processing engine in Rust using apache DataFusion, check us out at <a href="https://github.com/probably-nothing-labs/denormalized">https://github.com/probably-nothing-labs/denormalized</a><p>Hey HN,<p>We’d like to showcase a very early version of our embeddable stream processing engine called Denormalized. The rise of DuckDB has abundantly made it clear that even for many workloads of Terabyte scale, a single node system outshines the distributed query engines of previous generation such as Spark, Snowflake etc in terms of both performance and cost.<p>Now a lot of workloads DuckDB is used for were normally considered to be “big data” in the previous generation, but no more. In the context of streaming especially, this problem is more acute. A streaming system is designed to incrementally process large amounts of data over a period of time. Even on the upper end of scale, productionized use-cases of stream processing are rarely performing compute on more than tens of gigabytes of data at a given time.<p>Even so, the standard stream processing solutions such as Flink involve spinning up a distributed JVM cluster to even compute against the simplest of event streams. To that end, we’re building Denormalized designed to be embeddable in your applications and scale up to hundreds of thousands of events per second with a Flink-like dataflow API. While we currently only support Rust, we have plans for Python and Typescript bindings soon.<p>We’re built atop DataFusion and the Arrow ecosystems and currently support streaming joins as well as windowed aggregations on Kafka topics.<p>Please check out out repo at: <a href="https://github.com/probably-nothing-labs/denormalized">https://github.com/probably-nothing-labs/denormalized</a><p>We’d love to hear your feedback.

Show HN: An online 2D MMO game, written in Rust and JavaScript
I made a game (<a href="https://polyfight.io/" rel="nofollow">https://polyfight.io/</a>) which revolves around a player (a tank) leveling up and upgrading by killing shapes and other tanks (partially inspired by <a href="https://diep.io" rel="nofollow">https://diep.io</a>). It has a bunch of features, a vast number of tanks, an inbuilt chatting system, clans to make teams with your friends, a colour scheme maker, controllable sandboxes which can be public or private, a last man standing gamemode, and an inbuilt 1v1 system with its own ELO rankings and a global leaderboard. The game has a few players right now, and I'd hope to spread the joy players have with this game to people here, as well as any critiques people have about the game. Exploits/gray hat hacking is warmly welcomed, as I strive to make sure my game is secure and hard to script/bot in.
