Qbot
AI-powered Quantitative Investment Research Platform
...It bundles a lightweight GUI client (built with wxPython) and a modular backend so researchers can iterate on strategies, run batch backtests, and validate ideas in a near-real simulated environment that models latency and slippage. The project places special emphasis on AI-driven strategies — including supervised learning, reinforcement learning and multi-factor models — and offers a “model zoo” and example strategies to help users get started. For evaluation and analysis, Qbot integrates reporting and visualization (tearsheets, metrics) so you can compare performance across runs and inspect trade-level behavior. It supports multiple strategy runtimes and backtesting engines, is organized for extensibility (strategies live in a dedicated folder). -

PHP dotenv
Loads environment variables automatically
You should never store sensitive credentials in your code. Storing configuration in the environment is one of the tenets of a twelve-factor app. Anything that is likely to change between deployment environments, such as database credentials or credentials for 3rd party services, should be extracted from the code into environment variables. Basically, a .env file is an easy way to load custom configuration variables that your application needs without having to modify .htaccess files or... -

PWMScan
A Web-based genome-wide Position Weight Matrix (PWM) Scanner
PWMScan is used to scan a position weight matrix (PWM) against a genome or, in general, a large set of DNA sequences. The PWM is the most commonly used mathematical model to describe the DNA binding specificity of a transcription factor (TF). A PWM contains scores for each base at each position of the binding site. The TF binding score for a given k-mer sequence is then obtained by simply adding up the base-specific scores at respective positions of the binding site. PWMScan takes as... -
