...Just as Bigtable leverages the distributed data storage provided by the Google File System, Apache HBase provides Bigtable-like capabilities on top of Hadoop and HDFS. Thrift gateway and a REST-ful Web service that supports XML, Protobuf, and binary data encoding options. Support for exporting metrics via the Hadoop metrics subsystem to files or Ganglia; or via JMX. Convenient base classes for backing Hadoop MapReduce jobs with Apache HBase tables.

...Messaging patterns including publish/subscribe, request/reply and streaming. Financial grade transactional message. Built-in fault tolerance and high availability configuration options base on DLedger. A variety of cross language clients, such as Java, C/C++, Python, Go. Pluggable transport protocols, such as TCP, SSL, AIO. Built-in message tracing capability, also support opentracing. Versatile big-data and streaming ecosytem integration. Message retroactivity by time or offset. Reliable FIFO and strict ordered messaging in the same queue. ...

wZD is a server written in Go language that uses a modified version of the BoltDB database as a backend for saving and distributing any number of small and large files, NoSQL keys/values, in a compact form inside micro Bolt databases (archives), with distribution of files and values in BoltDB databases depending on the number of directories or subdirectories and the general structure of the directories. Using wZD can permanently solve the problem of a large number of files on any POSIX...

Abu Quantitative Integrated AI Big Data System, K-Line Pattern System, Classic Indicator System, Trend Analysis System, Time Series Dimension System, Statistical Probability System, and Traditional Moving Average System conduct in-depth quantitative analysis of investment varieties, completely crossing the user's complex code quantification stage, more suitable for ordinary people to use, towards the era of vectorization 2.0. The above system combines hundreds of seed quantitative models,...

...We pay special attention to the different ways to obtain data and how to make it manageable before starting the analysis. The data analysis includes most of the basic visualization options and some advanced extra options. Finally, basic statistics is used to learn from the processed data.

The article explains the design and the characteristics of a new open source content aggregation system. Among the features of the program, stands out a new processing engine of syndication channels, monitoring capability of information recovery in real time, the possibilities of the configuration of aggregator behavior, automatic classification of contents and new models for representation of information from relational interactive maps. On the other hand, the aggregation program, which...

The rocsy package is designed to accurately and efficiently compute all marine carbonate system variables from dissolved inorganic carbon (DIC), total alkalinity (Alk), temperature, and salinity as well as phosphate and silica concentrations. The pH scale and thermodynamic equilibrium constants used in rocsy are those recommended by Best-Practices Guide (Dickson et al., 2007). Also included are options to use more recent formulations for K1 and K2 from Millero (2010) and for total boron from Lee et al. (2010). The rocsy package is designed for users with some programming experience, preferably in Fortran or python. Others may well prefer the facility of packages such as the Excel version of CO2sys. But rocsy is computationally much faster, being designed for big data sets and ocean models. ...

...By default, the thermodynamic equilibrium constants used in mrocs are those recommended by Best-Practices Guide (Dickson et al., 2007). The mrocs package also includes options to use more recent formulations for K1 and K2 from Millero (2010) and for total boron from Lee et al. (2010). The mrocs package is designed for users with some programming experience, either in Fortran or python. Others would will prefer the facility of packages such as the Excel version of CO2sys. Because mrocs is computationally much faster, it is suited for big data and ocean models. ...
