    VeraCrypt

    VeraCrypt

    Open source disk encryption with strong security for the Paranoid

    VeraCrypt is a free disk encryption software brought to you by IDRIX (https://www.idrix.fr) and based on TrueCrypt 7.1a. It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. It also solves many vulnerabilities and security issues found in TrueCrypt. This enhanced security adds some delay ONLY to the opening of encrypted partitions without any performance impact to the application use phase. This is acceptable to the legitimate owner but it makes it much harder for an attacker to gain access to the encrypted data. All released files are PGP signed with key ID=0x680D16DE, available on key servers and downloadable at https://www.idrix.fr/VeraCrypt/VeraCrypt_PGP_public_key.asc VeraCrypt can mount TrueCrypt volumes. It also can convert them to VeraCrypt format. Documentation: https://www.veracrypt.fr/en/Documentation.html FAQ : https://www.veracrypt.fr/en/FAQ.html

    Octave Forge

    Octave Forge

    A collection of packages providing extra functionality for GNU Octave

    Octave Forge is a central location for collaborative development of packages for GNU Octave. The Octave Forge packages expand Octave's core functionality by providing field specific features via Octave's package system. See https://octave.sourceforge.io/packages.php for a list of all available packages. GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The Octave language is quite similar to Matlab so that most programs are easily portable. Refer to https://www.octave.org for more information.

    POSIX Threads for Windows

    An implementation of the POSIX threads API for Windows

    Also known as "pthreads-win32", POSIX Threads for Windows implements a large subset of the threads related API from the Single Unix Specification Version 3. Conformance and quality are high priorities of this mature library. Development began in 1998 and has continued with numerous significant professional contributions. Please note:- whilst PThreads4W can be built and run by it, MinGW64 includes it's own default POSIX Threads library called "winpthreads". The two are not compatible and in order to build and run PThreads4W (formerly PThreads-WIn32) MinGW64 must be installed without win32pthreads. If you want or need to build and run with PThreads4W then you need to choose win32 threading instead of POSIX when you install MinGW64 to not install the conflicting winpthreads include and library files.

    The SoX Resampler library

    The SoX Resampler library

    High quality, one-dimensional sample-rate conversion library

    The SoX Resampler library `libsoxr' performs one-dimensional sample-rate conversion—it may be used, for example, to resample PCM-encoded audio. It aims to give fast and high quality results for any constant (rational or irrational) resampling ratio. Phase-response, preserved bandwidth, aliasing, and rejection level parameters are all configurable; alternatively, simple `preset' configurations may be selected. An experimental, variable-rate resampling mode of operation is also included.

    whisper.cpp

    whisper.cpp

    Port of OpenAI's Whisper model in C/C++

    whisper.cpp is a lightweight, C/C++ reimplementation of OpenAI’s Whisper automatic speech recognition (ASR) model—designed for efficient, standalone transcription without external dependencies. The entire high-level implementation of the model is contained in whisper.h and whisper.cpp. The rest of the code is part of the ggml machine learning library. The command downloads the base.en model converted to custom ggml format and runs the inference on all .wav samples in the folder samples. whisper.cpp supports integer quantization of the Whisper ggml models. Quantized models require less memory and disk space and depending on the hardware can be processed more efficiently.

    Subread

    High-performance read alignment, quantification and mutation discovery

    The Subread software package is a tool kit for processing next-gen sequencing data. It includes Subread aligner, Subjunc exon-exon junction detector and featureCounts read summarization program. Subread aligner can be used to align both gDNA-seq and RNA-seq reads. Subjunc aligner was specified designed for the detection of exon-exon junction. For the mapping of RNA-seq reads, Subread performs local alignments and Subjunc performs global alignments. Subread and Subjunc were published in the following paper: Yang Liao, Gordon K Smyth and Wei Shi. "The Subread aligner: fast, accurate and scalable read mapping by seed-and-vote", Nucleic Acids Research, 2013, 41(10):e108
