Nitrous is a native desktop app for motorsport live timing and streaming. It connects to Formula 1 data feeds and presents live timing, car telemetry, trackmap, race control messages and session replay. Basic live timing and telemetry work without a subscription; streaming features such as F1 TV or the Driver Tracker Track Map require an active F1 subscription linked to the account. The app runs on macOS, Linux and Windows.
NONCODE is an integrated knowledge database dedicated to non-coding RNAs, excluding tRNAs and rRNAs, with a focus on lncRNAs. The current version is v6.0. It offers browsing by species and type, searching entries, statistics, BLAST similarity searches, disease-related information, genome locations, ID conversion, downloads, predicted functions and cross-species conservation.
Nootka is an application for learning classical score notation, helping users understand the basics of reading and practicing musical scores. The user plays notes displayed by the app, which checks in real time whether they were played correctly. The application is free and open source.
NotKYC is a curated directory of privacy-respecting services, exchanges, VPNs and tools that do not require KYC. Entries listed on the site include exchanges such as BasicSwap and Bisq, hosting providers, and VPNs such as Mullvad VPN. Individual pages describe listed services, including the Cock.li email provider and the eigenwallet Bitcoin wallet.
The Nucleic Acid Knowledgebase (NAKB) is a portal for 3D structural information about nucleic acids, succeeding the Nucleic Acid Database. It provides annotations, search, reports, statistics, an atlas and visualization for nucleic-acid containing structures held by the NDB and the Protein Data Bank, covering X-ray, electron microscopy and NMR methods. Each structure links to external resources annotating and analyzing nucleic acid structures and their complexes.
Oculante is an open-source image viewer and editor for Windows, Mac, Linux, FreeBSD and NetBSD. It offers basic image analysis and nondestructive editing tools such as cropping, resizing, painting, rotating and blurring. The project is currently in maintenance mode, accepting only bug fixes and minor improvements to existing features until a rewrite is completed.
The Online Mendelian Inheritance in Animals (OMIA) is a catalogue of inherited disorders, single-locus traits, and associated genes and variants in 795 mostly vertebrate animal species, excluding humans, mice, rats, zebrafish, and the western clawed frog. The University of Sydney resource is manually curated and stores textual information, references, and links to NCBI, OMIM, Ensembl, Mondo, and VBO records.
Open Tree of Life is a project that aims to make phylogenetic knowledge more accessible. The platform enables users to explore previously published phylogenetic tree estimates and synthetic phylogeny estimates generated from multiple datasets. Users can contribute to the project by uploading trees or linking trees in the system to the underlying data they are based on, to help improve the system's comprehensiveness.
OpenAsar is a client modification for Discord that aims to speed up startup and reduce size. It also offers basic theming through custom CSS and splash screens, plus configurable options, and is stated to work alongside other mods and across operating systems and Discord versions.
OpenWorm is an open source project that aims to create a virtual C. elegans nematode in a computer. Its sub-projects include a worm body simulator with physics of muscles, soft tissues and fluids, WormSim for interacting with the worm in a browser, DevoWorm for developmental processes, a 3D Browser, the NeuroML Connectome, and Geppetto. Code and models are released under the MIT licence.
Oral Cancer Gene Database is a research resource focused on oral cancer genomic and proteomic data. It offers access to gene lists, keyword search functionality, and interaction networks to support research into oral cancer diagnosis, prognosis and treatment.
OrtholugeDB is a database of Ortholuge-based orthology predictions for completely sequenced bacterial and archaeal genomes. It also contains reciprocal best hit-based ortholog predictions, in-paralog predictions and proposed ortholog groups. Users can compare orthologs across multiple genomes, obtain orthologs between two genomes or for a single gene, and filter results by strain.
OverTheWire is a community offering wargames intended to help people learn and practice security concepts through games. Its suggested order begins with Bandit for Unix/Linux basics, followed by a choice among Natas for web security, Krypton for cryptography or Leviathan for reverse engineering, then binary exploitation games. Each shell game uses its own SSH port.
A free, evolving tutorial on cryptography maintained since 1999. It covers basic cryptographic concepts, types of algorithms including secret key, public key and hash functions, trust models, and applied algorithms in action.
Paintable is a digital painting education site offering free tutorials, project briefs, and resources, plus a community academy with video lessons and feedback. Its Digital Painting Academy offers 370+ video lessons, monthly workshops, and constructive feedback, with a 7-day free trial. The separate Illustration From Imagination program is described as intensive and requires a base knowledge of basics.
PathCards is an integrated database of human biological pathways and their annotations. Human pathways are clustered into SuperPaths based on gene content similarity, and each PathCard describes one SuperPath that represents one or more human pathways. It contains 1,686 SuperPath entries consolidated from 11 selected web sources and is modeled on the GeneCards database architecture.
Pathway Commons collects and disseminates biological pathway and interaction data from partner databases, represented in the BioPAX standard. It provides search, visualization and web services, downloadable files in BioPAX, SIF and GMT formats, and tools such as PCViz, CyPath2, PaxToolsR and ChiBE. All data and software are free and open-source.
