Apache Storm

Compare

Claimed by Apache Software Foundation Analyzed about 4 hours ago

Storm is a free and open source distributed realtime computation system. Storm makes it easy to reliably process unbounded streams of data, doing for realtime processing what Hadoop did for batch processing. Storm is simple, can be used with any programming language. Storm is fast: a benchmark ... [More] clocked it at over a million tuples processed per second per node. It is scalable, fault-tolerant, guarantees your data will be processed, and is easy to set up and operate. Storm integrates with the queueing and database technologies you already use. A Storm topology consumes streams of data and processes those streams in arbitrarily complex ways, repartitioning the streams between each stage of the computation however needed. [Less]

netdata

Compare

  Analyzed about 15 hours ago

Real-time performance monitoring, in the greatest possible detail. Netdata is the fastest way to visualize metrics. It is a resource efficient, highly optimized system for collecting and visualizing any type of real-time timeseries data, from CPU usage, disk activity, Network and QoS traffic, SQL ... [More] queries, API calls, web site visitors, etc. Netdata tries to visualize the truth of now, in its greatest detail, so that you can get insights of what is happening now and what just happened, on your systems and applications. For collecting data, it supports external plugins, even shell or node.js plugins. Any computer program, in any language, that can print a few lines of text on its standard output, can be a netdata data collector. [Less]

Milkymist

Compare

  Analyzed about 4 hours ago

The project develops a stand-alone device in a small form factor that is capable of rendering MilkDrop-esque visuals effects in real time, with a high level of interaction with many sensors and using live audio and video streams as a base. Open source components and design tools have been developed ... [More] or used as much as possible. A system-on-chip implemented in a FPGA has been chosen for meeting this goal at the IP core level. The flexibility of the FPGA enables advanced users to modify the design, and also permits compact integration of many interfaces (MIDI, OSC, DMX512, analog sensors, video inputs), making Milkymist™ a platform of choice for the mobile VJ. The design is also highly modular and documented, making the code easy to re-use in other open source system-on-chips. [Less]
