Jesse
An advanced crypto trading bot written in Python
Jesse is an open-source AI agent framework designed to help developers build and orchestrate intelligent workflows that combine large language models (LLMs) with external tools, automation logic, and real-world actions. It acts as an agent manager where you can define tasks, contexts, and tool integrations so that AI reasoning is reliably connected to deterministic procedures like API calls, data retrieval, and task execution. Jesse emphasizes structured outputs, safety boundaries, and explainable reasoning, helping users design agents that don’t just hallucinate responses but can coordinate steps, validate conditions, and interact with systems predictably. It also includes built-in support for evaluation, logging, and orchestration so developers can monitor, test, and improve agent behavior over time. Because it’s framework-agnostic with respect to model providers, Jesse can work with different LLM backends, giving teams flexibility in cost and capability trade-offs. -

No Coin
No Coin is a tiny browser extension aiming to block coin miners
No coin is a tiny browser extension aiming to block coin miners such as Coinhive. Even though I think using coin mining in browser to monetize content is a great idea, abusing it is not. Some websites are running it during the entire browsing session which results in high consumption of your computer's resources. I do believe that using it occasionally such as for the proof of work of a captcha is OK. But for an entire browsing session, the user should have the choice to opt-in which is the aim of this extension. The idea was to keep it separate from adblocking. Coin mining in the browser is a different issue. Where ads are tracking you and visually interfering with your browsing experience, coin mining, if abused, is eating your computer resources resulting in slow downs (from high CPU usage) and excessive power consumption. You might be OK with that and not with ads, or vice versa. Or you might just want to keep ads blocked entirely and just enable the coin mining script. -
