Big-O Cheatsheet is a webpage presenting space and time Big-O complexities of common computer science algorithms. It includes a Big-O complexity chart, common data structure operations with average and worst case time complexity and space complexity, and array sorting algorithms with best, average and worst case time complexity. A downloadable PDF version is offered.
A website listing upcoming rocket launches to space, with an overview including launch time, payload and destination. It offers countdowns and filters by launch service provider, launch vehicle, payload, destination and date.
Space Atlas is a free, interactive 3D map of tracked satellites and rocket bodies orbiting Earth, described as covering objects from Sputnik in 1957 to today. It displays about 22,242 objects in orbit and offers real-time tracking, a timeline scrubber, and a view of satellites passing over the user's location. Orbits are approximated from the public CelesTrak catalog.
SpaceEngine is a virtual universe simulator for computers. Users can travel from star to star and galaxy to galaxy, landing on planets, moons and asteroids, and can alter the speed of time. Real celestial objects appear alongside procedurally generated regions based on scientific knowledge.
Real-Time Text-to-Image SDXL Lightning is a Hugging Face Space created by user radames. It allows users to input a text description of a desired image, with optional adjustments to seed and guidance strength. The application generates a matching image and provides it as a downloadable file using the SDXL Lightning model for fast generation.
The Satellite Data Services group at the University of Wisconsin-Madison Space Science and Engineering Center handles access, maintenance and distribution of real-time and archive weather satellite data. It offers real-time data access, online GOES and non-GOES geostationary archives, and a conventional data archive.
Camel Agents is a Hugging Face Space developed by camel-ai that launches an AI agent system capable of concurrent task processing. Users must provide an API key and specify the number of tasks to run at the same time to use the system.
Celestia is a free space simulator that provides real-time 3D visualization of space. It displays objects and orbits based on scientific data and runs on Windows, Linux, macOS, iOS and Android. Users can travel through the solar system, to over 100,000 stars, or beyond the galaxy. Its catalogues are expandable with add-ons, and users can create their own objects and planetary systems.
searx.space is a directory of online and offline SearXNG instances. The site lists 70 currently online SearXNG instances, and tracks instance status including offline, connection timed out, HTTP client and server errors. For each listed instance, it displays details such as URL, software version, TLS configuration, security scores, certificate information, IPv6 support, country, associated network, search response times and uptime. Users can submit requests to add or remove instances via GitHub issues, and can filter out networks with known privacy issues.
Solar Dynamics Observatory (SDO) is a NASA mission designed to study the solar atmosphere at fine space and time scales across multiple wavelengths to understand the Sun’s influence on Earth and near-Earth space. Its associated portal provides access to mission data, spacecraft specifications, instrument details, scientific publications, observation event information, and outreach resources.
SolarHam is a space weather and aurora website founded in 2006. It provides real time data and new updates, including solar indices, imagery, flare probabilities and geomagnetic forecasts. Its help center explains space weather terms such as coronal holes, coronal mass ejections and geomagnetic storms, and notes that the section is being built.
A Hugging Face Space that shows a real-time simulation in which autonomous AI traders buy and sell in a virtual market. It requires no input; opening the page displays a scrolling ticker and current market condition.
EarthByte is a research group at the University of Sydney's School of Geosciences. It pursues geodata synthesis through space and time, building a deep-time virtual Earth, and is known for collaborative software development, big data analysis and open access digital data collections. It leads development of open-source virtual Earth software including GPlates and pyGPlates.
Real-Time Latent Consistency Model Text to Image creates or edits images with generative AI and text-based controls.
Real-Time Latent Consistency Model Text-to-Image-Lora-SD1.5 creates or edits images with generative AI and text-based controls.
Open ASR Leaderboard is a Hugging Face Space that provides a searchable leaderboard of speech-recognition models. It displays word-error rates, real-time factors and model sizes across many languages and datasets, and users can select which entries to view.
Awesome Docker is a page about a file containing Docker services. It notes the file is becoming too large to handle and that docker run commands and compose files may be removed, with services possibly removed over time to free up space.
Bartosz Ciechanowski's site presents interactive articles about science and engineering, including an article on the Moon covering its motion in space, its illumination, and its path around Earth. The articles include draggable visualizations and sliders for controlling viewpoint and date and time.
CDAWeb is a service of NASA's Space Physics Data Facility that holds selected public non-solar heliophysics data from current and past missions and projects. It supports creating data subsets by date and variables, uniformly time binned data, plots in PDF, PS and PNG formats, and movies of image sequences. All SPDF services are unavailable during monthly system maintenance.
Docmost is an open-source, self-hosted collaborative wiki and documentation tool presented as an alternative to Notion and Confluence. It offers real-time collaborative editing, team spaces with permissions, comments, page history, public sharing, nested navigation and diagramming tools. An optional enterprise edition adds SSO, AI and API access. It can run in air-gapped environments with no external dependencies.
IANA performs the global coordination of the DNS Root, IP addressing, and other Internet protocol resources. It manages the DNS Root Zone, the .int and .arpa registries, and the IDN Practices Repository, and coordinates global IP and AS number spaces. It also maintains protocol name and number registries and a time zone database.
