Cloud Run is the fastest way to deploy containerized apps. Push your code in Go, Python, Node.js, Java, or any language and Cloud Run builds and deploys it automatically. Get fast autoscaling, pay only when your code runs, and skip the infrastructure headaches. Two million requests free per month. And new customers get $300 in free credit.
X-ray diffraction (XRD) analysis for hkl simulation of any crystal.
Crystalsim is a simple freeware program with a neat graphical user interface for X-ray diffraction (XRD) data analysis .
It can simulates all possible {hkl} planes data for the selected crystal.
Crystallographic Information File (.cif) can also be used.
Analyze both powder diffraction and single crystal data .
Indexed at International Union of Crystallography (IUCR).
Crystalline lattice parameters such as ‘a’, ‘b’, ‘c’ as well as interfacial angles such as alpha, beta,...
finds exact gain, directivity and input impedance of Yagi or log-periodic antennas (planar symmetric array of cylindrical dipoles, many driven elements) for a range of specified frequencies, integrates 2D for segments on the same element, moment method
ORIPA S is a drawing tool specifically designed for a origami crease pattern. It is derived from ORIPA which is developed by MITANI Jun.
New features by ORIPA S are:
- save current crease pattern as a image file (jpeg, png) not only original project file.
- while pasting, select a point on pattern to be matched against destination point.
- Some considerable bugs are fixed (i.e., wrong undo behavior on ORIPA v0.35).
An artificial neural network, currently specialized to save a specific bit pattern, mainly by changing the signal propagation delays in links. More features, variables and algorithms will be added in time.

Vertex AI gives developers access to Gemini 3—Google’s most advanced reasoning and coding model—plus 200+ foundation models including Claude, Llama, and Gemma. Build generative AI apps with Vertex AI Studio, customize with fine-tuning, and deploy to production with enterprise-grade MLOps. New customers get $300 in free credits.
Knitter produces a 3-dimensional model of a knitting pattern. It supports KnitML, as well as a native language similar to that of traditional knitting patterns.
DimReduction project provide an open-source multiplatform (Java) graphical environment for bioinformatics problems that supports many feature selection algorithms, pattern recognition techniques, criterion functions and graphic visualization tools.
Seems to be closely related to Cellular automaton, except this creates a complex pattern from a mathematical function you input. See website for examples/live applets. This program makes use of an old GPL version of the JEP equation parser.
Arcus is a Rubik's Cube Simulator written in Java featuring 3D display and cube manipulation. Besides conventional solving, getting from any pattern to any goal pattern is supported. Allows the user to bidirectionally walk through the cube's history.
Stop waiting on engineering. Build production-ready internal tools with AI—on your company data, in your cloud.
Retool lets you generate dashboards, admin panels, and workflows directly on your data. Type something like “Build me a revenue dashboard on my Stripe data” and get a working app with security, permissions, and compliance built in from day one. Whether on our cloud or self-hosted, create the internal software your team needs without compromising enterprise standards or control.
EventListener is a simple and efficient C++ framework for propagating Events in graphical interfaces or numerical codes, using Listener pattern. Filtering and blocking of events is possible. This package does not use any other lib.
