1. On clock faces, 4 is Expressed as IIII, not IV Total comment counts : 40 Summary This article discusses the use of Roman numerals on clocks and the unconventional notation of “4” as “IIII” instead of “IV”.

1. Spreadsheets are all you need Total comment counts : 40 Summary The article discusses a low-code introduction to Large Language Models (LLMs) called “Spreadsheets-are-all-you-need.” It explains that the implementation of the forward pass of GPT2 (a predecessor to ChatGPT) is done entirely in Excel using standard spreadsheet functions. The article mentions that this same Transformer architecture is used in various LLMs such as OpenAI’s ChatGPT and Google’s Bard/Gemini. It provides a 10-minute demo video that walks through the high-level architecture of GPT2 and how it is implemented in an Excel spreadsheet....

1. JIT WireGuard Total comment counts : 20 Summary The article is about Fly.io, a company that uses WireGuard to make their system faster and more scalable. They have implemented WireGuard in unique ways, such as conjuring a TCP/IP stack for every instance of their CLI. However, they encountered two problems: unreliable message delivery with NATS and leftover WireGuard peers after running flyctl. To solve these issues, they decided to have gateways pull configurations from their API on demand instead of pushing them....

1. Fine tune a 70B language model at home Total comment counts : 42 Summary Answer.AI has released a fully open-source system that allows the efficient training of a 70 billion parameter language model on a regular desktop computer with gaming GPUs. This collaboration between Answer.AI, Tim Dettmers, and Hugging Face’s Titus von Koeller and Sourab Mangrulkar aims to make better models accessible to the open-source community. The system enables small labs to access large models and brings high-performance gaming GPUs, which are much cheaper than data center GPUs, into the training process....
