DBToaster - Welcome to dbtoaster.org
Engine for continuous analytical queries. Sounds similar to PipelineDB (https://www.pipelinedb.com/, Noria, maybe KQSL.

DBToaster is an SQL-to-native-code compiler. It generates lightweight, specialized, embeddable query engines for applications that require real-time, low-latency data processing and monitoring capabilities. The DBToaster compiler generates code that can be easily incorporated into any C++ or JVM-based (Java, Scala, ...) project.

Since 2009, DBToaster has spearheaded the currently ongoing database compilers revolution. If you are looking for the fastest possible execution of continuous analytical queries, DBToaster is the answer. DBToaster code is 3-6 orders of magnitude faster than all other systems known to us.

tcptrace - Official Homepage
tcptrace is a tool written by Shawn Ostermann at Ohio University, for analysis of TCP dump files. It can take as input the files produced by several popular packet-capture programs, including tcpdump, snoop, etherpeek, HP Net Metrix, and WinDump. tcptrace can produce several different types of output containing information on each connection seen, such as elapsed time, bytes and segments sent and received, retransmissions, round trip times, window advertisements, throughput, and more. It can also produce a number of graphs for further analysis.

ELKI Data Mining Framework
Datamining software in Java with algorithms focused on unsupervised cluster analysis and outlier detection. AGPLv3. Alleges to use smart data structures or "index structures" perhaps meaning the data is laid out linearly but there are indexes to access it (e.g. R* tree).

airbnb/superset: Superset is a data exploration platform designed to be visual, intuitive, and interactive
Superset is a data exploration platform designed to be visual, intuitive and interactive.

[this project used to be named Caravel, and Panoramix in the past]

Compare with Pivot, maybe Grafana. Also compare to a lightweight Tableau!

Originally designed as a UI for Druid, now also supports a SQL backend via SQAlchemy.

CodeCity
CodeCity is an integrated environment for software analysis, in which software systems are visualized as interactive, navigable 3D cities. The classes are represented as buildings in the city, while the packages are depicted as the districts in which the buildings reside. The visible properties of the city artifacts depict a set of chosen software metrics, as in the polymetric views of CodeCrawler.

The USE Method
The Utilization Saturation and Errors (USE) Method is a methodology for analyzing the performance of any system. It directs the construction of a checklist, which for server analysis can be used for quickly identifying resource bottlenecks or errors. It begins by posing questions, and then seeks answers, instead of beginning with given metrics (partial answers) and trying to work backwards.

UA string analysis :: user-agent-string.info
This tool was developed for user agent string analysis. Our analysis gives you information on client SW type (browser, webcrawler, anonymizer etc.), which OS is used by the client and moreover we display detailed analysis of UA fragments together with the URL of client's SW producer and our commentary.

google-refine - Project Hosting on Google Code
pretty awesome downloadable tool to interact with data, like an uber-spreadsheet. Great for cleaning up/normalizing dirty datasets.

This is the same thing as Freebase's Gridworks, just re-released under Google's name since they just bought Freebase.

SNAP: Stanford Network Analysis Platform
SNAP is a general purpose network analysis and graph mining library. It is written in C++ and easily scales to massive networks with hundreds of millions of nodes, and billions of edges. It efficiently manipulates large graphs, calculates structural properties, generates regular and random graphs, and supports attributes on nodes and edges.
