Titan: Distributed Graph Database Titan is a scalable graph database optimized for storing and querying graphs containing hundreds of billions of vertices and edges distributed across a multi-machine cluster. Titan is a transactional database that can support thousands of concurrent users executing complex graph traversals in real time. In addition, Titan provides the following features: Download Titan or clone from GitHub. 24 Essential Mind Mapping and Brainstorming Tools Mind mapping is the process of using visual diagrams to show the relationships between ideas or information. Its popular uses include project planning, collecting and organizing thoughts, brainstorming and presentations — all in order to help solve problems, map out resources and uncover new ideas. It can be more useful than trying to keep track of our ideas by scribbling them on paper, and can aid in manipulating and generating concepts. We've compiled a list of 24 mind mapping tools to help you organize, summarize and visualize information, with both free and paid versions available to suit any budget or requirement. The tools mentioned are either browser- or desktop-based, with a selection of mind mapping mobile apps at the end of the article for use on iOS and Android devices.

Graph database Graph databases employ nodes, properties, and edges. List of Graph Database[edit] The following is a list of several well-known graph databases: Features[edit] Welcome to Jinja2 — Jinja2 2.7.2 documentation Jinja2 is a modern and designer friendly templating language for Python, modelled after Django’s templates. It is fast, widely used and secure with the optional sandboxed template execution environment: <title>{% block title %}{% endblock %}</title><ul>{% for user in users %} <li><a href="{{ user.url }}">{{ user.username }}</a></li>{% endfor %}</ul> Features: sandboxed executionpowerful automatic HTML escaping system for XSS preventiontemplate inheritancecompiles down to the optimal python code just in timeoptional ahead of time template compilationeasy to debug.

Berkeley DB Java Edition Oracle Berkeley DB Java Edition is an open source, embeddable, transactional storage engine written entirely in Java. It takes full advantage of the Java environment to simplify development and deployment. The architecture of Oracle Berkeley DB Java Edition supports very high performance and concurrency for both read-intensive and write-intensive workloads. Depending on your needs choose between Berkeley DB Java Edition's Direct Persistence Layer (DPL), Persistent Collections API, or simply store key/value pairs of arbitrary data. If your application requires something outside the bounds of relational databases then Berkeley DB Java Edition is likely to be the best choice.

30+ Mind Mapping Tools We all need to organize our thoughts sometimes, and there seems to be no better way to do it than in a visual fashion. We've got 30+ mind mapping tools to help you do just that. And since we know some of you are on a budget, we've got free and paid suggestions for you. Blazegraph GPU Mapgraph is SYSTAP’s disruptive new technology to exploit the main memory bandwidth advantages of GPUs. The original work was (partially) funded by the DARPA XDATA program under AFRLContract #FA8750-13-C-0002 and the Defense Advanced Research Projects Agency (DARPA) under Contract No. D14PC00029. The early work was co-developed with the University of Utah SCI Institute and has its pedigree in the UINTAH software running on over 750M cores on the TITAN Super Computer.

TrackEye : Real-Time Tracking Of Human Eyes Using a Webcam Introduction Eyes are the most important features of the human face. So effective usage of eye movements as a communication technique in user-to-computer interfaces can find place in various application areas. Eye tracking and the information provided by the eye features have the potential to become an interesting way of communicating with a computer in a human-computer interaction (HCI) system. Representing time dependent graphs in Neo4j · SocioPatterns/neo4j-dynagraph Wiki Background Large-scale data collection efforts using wearable sensors to mine for proximity of individuals (for example, the SocioPatterns project) produce time-varying social graphs, where nodes are individuals, edges represent proximity/contact relations of individuals, and the proximity graph changes over time. Both nodes and edges can have rich attributes. Data formats for exchanging the time-dependent graphs are available, see for instance the GEXF format. Efficiently mining large time-dependent graphs, however, requires a database and a representation that can support complex topological queries, temporal queries, multi-scale temporal indexing and aggregation, and more. A growing research community working on temporal networks may benefit from sound and efficient techniques to represent, store and query dynamic graphs.

The Ultimate Guide to Mind Maps and Mind Mapping Tools What Are Mind Maps? Mind Maps are a way of visually organizing information that help you identify and understand the structure of a subject at a glance. They allow you to create logical connections between concepts that show how pieces of information fit together, providing you with a “map” of your ideas, processes, and concepts. You can use mind maps for many things such as outlining presentations, ebooks, and content plans, engaging in logical problem solving, and mapping out user experiences online and in the real world.

Blog - Using Datomic as a Graph Database Datomic is a database that changes the way that you think about databases. It also happens to be effective at modeling graph data and was a great fit for performing graph traversal in a recent project I built. I started out building kevinbacon.us using Neo4j, a popular open-source graph database. It worked very well for actors that were a few hops away, but finding paths between actors with more than 5 hops proved problematic. The cypher query language gave me little visibility into the graph algorithms actually being executed. I wanted more.
