Trixi.jl is a numerical simulation framework for hyperbolic conservation laws written in Julia. A key objective for the framework is to be useful to both scientists and students. Therefore, next to having an extensible design with a fast implementation, Trixi.jl is focused on being easy to use for new or inexperienced users, including the installation and postprocessing procedures.

UQLM is a Python library developed to detect hallucinations and quantify uncertainty in the outputs of large language models. The system implements a variety of uncertainty quantification techniques that assign confidence scores to model responses. These scores help developers determine how likely a generated answer is to contain errors or fabricated information. The library includes both black-box and white-box approaches to uncertainty estimation. Black-box methods evaluate model outputs...

VDT - Visual Disk Test : performs I/O tests on files, partitions, and/or disks with visual feedback/follow-up, offering flexible test area selection by size, location, percent, or combinations thereof, plus test duration control by time or size.

...XSRFProbe performs numerous systematic checks to determine whether a web endpoint is vulnerable, including inspection of anti-CSRF tokens, cookie validation behavior, and request forgery scenarios. It also analyzes the strength and randomness of security tokens using algorithms such as entropy calculations to determine whether tokens can be predicted or forged. When a vulnerability is discovered, it can automatically generate proof-of-concept payloads that demonstrate how the flaw could be exploited in a real attack scenario. XSRFProbe provides a highly automated workflow while still allowing users to customize scanning behavior and configuration settings.

...Currently, it includes the software systems KReator and MECore and the library Log4KR: - KReator is an integrated development environment (IDE) for relational probabilistic knowledge representation languages such as Bayesian Logic Programs (BLPs), Markov Logic Networks (MLNs), Relational Maximum Entropy (RME), First-Order Probabilistic Conditional Logic (FO-PCL), and others. - MECore is a shell-based system that allows the user to create propositional knowledge bases, to perform a variety of belief change operations, and to query a knowledge base with respect to the principle of optimum entropy. - Log4KR is a library providing data structures to represent knowledge bases in various logic formalisms (propositional, relational, conditional, probabilistic, ...) and providing algorithms to perform reasoning operations

NSB entropy and mutual information estimator; applications to the analysis of neural code.

...The passphrase-generator defaults to only 3 words instead of the 4 suggested by XKCD, but uses a larger dictionary found in many unix like systems at /usr/share/dict/words. It also provides estimates for the entropy of the generated passphrases. The randomization is based on /dev/urandom and SHA1. See http://xkcd.com/936/ for an entertaining take on passwords vs. passphrases. See my post in stackoverflow for links to other solutions and discussions on passphrases vs passwords: http://stackoverflow.com/a/12646320/1148030

...The approach is vulnerability driven and in order to get as much unbiased results, it makes use of the National Vulnerability Database. This work is mainly based on the following publications: *C.
