There are a few different ways to implement them, but the most talked and marketed about is to use feature flag management software. The simplest way of course is to hardcode them, though it’s the least written about. While feature flag management software can be powerful, they are also a source of complexity and risk. The blogspam marketing behind them is so strong, that admitting they’re unnecessary feels…

🚀 Read this insightful post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: If you have looked into flow batteries for any length of time, you will have found that the ferrocyanide/ferricyanide redox couple ( [Fe(CN)6] 4−, Fe(CN)6] 3−) is one of the most widely used in the field. This is because this redox couple has very high redox stability, great kinetics, significant solubility (0.7-1.2M depending on the exact salts used) and a redox potential that is lower to that of the Fe2+/Fe3+ redox couple (+0.22V and +0.5V respectively Vs saturated Ag/AgCl), with high stability under high pH conditions. Potassium ferrocyanide,…

They understand how worlds appear, behave, and evolve so that we can render imagined worlds for creative users, simulate the real world in high fidelity, and help robots plan actions. At World Labs, we build these general purpose world models in pursuit of spatial intelligence. Today we are introducing Atlas, our next-generation world model. Atlas is an omni model that we pretrained from scratch to natively operate on text, images, video, and 3D. It is a…

The OpenAI Codex desktop app (since rebranded to just ChatGPT) has 1.7GB of stuff in there in a folder called codex-primary-runtime, including a full Python installation, a full Node.js installation, and native binaries for Poppler, git, and the LibreOffice open source office suite (which forked from OpenOffice.org in 2010): The ~/.cache/codex-runtimes/codex-primary-runtime/plugins/openai-primary-runtime/plugins/documents folder includes skills which tell Codex how to find and use those binaries. ⚡ **What’s your…
