BOLDv5 has a redesigned layout, while BOLDv4 remains accessible at v4.boldsystems.org.
The Community Coordinated Modeling Center is a multi-agency partnership at NASA Goddard Space Flight Center that supports research and development for space science and space weather models. It provides free access to research models through an automated model run system, along with online visualization and analysis tools, model validation, forecasting support, and education resources.
A page from the Fake Name Generator that checks a credit card number's network, length and Luhn check digit. It explains the Luhn check step by step and offers sample made-up numbers for testing forms. The page notes the sample numbers are not accounts and are declined by payment gateways.
Dr. Link Check is a broken link checker that crawls a website from a start URL through its HTML and CSS, examining internal and outbound links plus links to images, style sheets, and other resource files. Each link passes multiple checks, including URL validation, DNS lookup, connect check, SSL certificate check, and HTTP response check. Results can be sorted, filtered, and exported to CSV.
Email Dossier is a validation tool that checks an email address by walking through the process of sending email without actually sending any. It checks address syntax, looks up the domain's mail servers and tries contacting them. It reports a confidence rating from 0 to 3, error codes, a canonical address and MX records.
Hunter tool for verifying if an email address is valid, deliverable, and safe to use before outreach.
A global resource for 3D electron microscopy structure data, covering archiving and retrieval of structures along with news, events, software tools, data standards and validation methods. It reports recent EMDB map entries and PDB coordinate entries.
emudev.org is a network of people interested in documenting, emulating, simulating and re-implementing hardware near extinction. Its stated purpose is preserving platforms designed or used for gaming and other artistic endeavors. Goals include publishing standardized hardware documentation, tests and validation suites, and reference software and hardware cores. All information, source code and designs are made available at no cost under liberal licenses.
Forefront is described as a platform to fine-tune and inference open-source language models. The site mentions building with open-source AI, fine-tuning models on data, and running inference through serverless API endpoints. It also describes storing training, validation and evaluation data in ready-to-fine-tune datasets. Pricing lists a free tier and a team plan at $99 per month, each including $20 in free credits.
Intelligence X is a provider of free open source intelligence (OSINT) and forensic tools for investigations. Its toolset supports search across third-party sites, social media intelligence for Facebook, Twitter, LinkedIn, Telegram, and YouTube, and utilities for tasks including email validation, domain lookups, IP lookups, Bitcoin tracing, and image analysis. All listed OSINT and forensic tools are available to use at no cost.
The ISRCTN registry is a clinical study registry recognised by the WHO and ICMJE that accepts proposed, ongoing and completed clinical research studies. It provides content validation, curation and unique identification numbers needed for publication, and all study records are freely accessible and searchable. Registration is ideally prospective, though retrospective registration is accepted.
