THE SUPER EFFECTIVENESS OF POKÉMON EMBEDDINGS USING ONLY RAW JSON AND IMAGES

Embeddings are numerical representations of objects often used in text analysis and search applications. LLMs like BERT and newer models with larger context windows can generate embeddings for text data, taking into account word position and punctuation for better contextual understanding. These embeddings can be used to identify similar items. This author explores embeddings by encoding Pokemon data, including both text and image data, into embeddings and analyzing their similarities. By combining text and image embeddings and using dimensionality reduction techniques like UMAP, the author was able to visualize and analyze relationships between Pokemon.

THE ECONOMICS OF WRITING TECHNICAL BOOKS

Technical authors can make a decent income from their books, but they should not write them solely for monetary reasons. The amount of money earned varies depending on the distribution channel, with self-publishing platforms like Gumroad and Leanpub offering higher royalties than traditional publishers. Technical books can generate passive income over a long period, with some titles remaining relevant for decades. However, most technical books sell less than 5,000 copies per year.

BYTECODE BREAKDOWN: UNRAVELING FACTORIO'S LUA SECURITY FLAWS

Factorio, a popular game, uses Lua for game logic and modding, allowing Lua code execution on the client-side for multiplayer synchronization. However, the Lua implementation in Factorio is vulnerable to exploitation through malicious custom maps that bypass the bytecode verifier, allowing arbitrary code execution. The vulnerability, which enables attackers to create malicious bytecode and execute it on the client, is caused by the absence of an official bytecode verifier in Lua 5.2.1 and the presence of off-by-one issues in Factorio's custom implementation.
