- Welcome to Apache Hadoop! – The Apache Hadoop project develops open-source software for reliable, scalable, distributed computing. Hadoop includes these subprojects:
* Hadoop Common: The common utilities that support the other Hadoop subprojects.
* Avro: A data serialization system that provides dynamic integration with scripting languages.
* Chukwa: A data collection system for managing large distributed systems.
* HBase: A scalable, distributed database that supports structured data storage for large tables.
* HDFS: A distributed file system that provides high throughput access to application data.
* Hive: A data warehouse infrastructure that provides data summarization and ad hoc querying.
* MapReduce: A software framework for distributed processing of large data sets on compute clusters.
* Pig: A high-level data-flow language and execution framework for parallel computation.
* ZooKeeper: A high-performance coordination service for distributed applications.

- Metric Conversion. Unit Conversion. Online Measurement Unit Converter. Conversion Table. – If you are need any kind of conversion you are at the right place. We offer wide range of online conversions between different units of measurement. Here you make time, data, speed, temperature, currency and a lot of other conversions. Please start by choosing the conversion type.
- Algorithmic Thermodynamics.pdf (application/pdf Object) – …one of the fun things we noticed is that algorithmic entropy is a special case of Gibbs entropy — but only if we generalize a bit and use relative entropy. They say “everything is relative”. I don’t know if that’s true, but it’s sure true for entropy.
- r4stats.com: R info for SAS, SPSS, and Stata Users – R has over 3,000 add-on packages, many containing multiple procedures, so it can do most of the things that SAS and SPSS can do and quite a bit more. The table below focuses only on SAS and SPSS products and which of them have counterparts in R. As a result, some categories are extremely broad (e.g. regression) while others are quite narrow (e.g. conjoint analysis). This table does not contain the hundreds of R packages that have no counterparts in the form of SAS or SPSS products. There are many important topics (e.g. mixed models, survival analysis) offered by all three that are not listed because neither SAS Institute nor IBM’s SPSS Company sell a product focused just on that.
- flattr – We aim to revolutionize how people pay and get paid for content on the internet. Come, join and show the world that good content is worth some coins out of your pocket.

- Revolutions: How to combine Google maps and data in R – Every good artist needs a canvas, and when it comes to displaying geographic data placing those data in context — on a map — makes all the difference. A new package for R from Markus Loecher, RgoogleMaps, allows you to download a street or satellite map from Google simply by specifying the bounding latitude/longitude coordinates. (You need to sign up for a free Google API key first, though.) You can then overlay data from objects in R, using tools provided to convert to the map-based coordinate system. Here’s an example from the package vignette overlaying the locations of faults (provided as data in the geomapdata package) on a satellite map:
- Data munging with SQL and R.pdf (application/pdf Object) – …while it is possible to shoe-horn a one-to-one mapping of SQL clauses with R functions, R generally has better ways of going about things. In the example that we are about to walk through, experienced R users will think of more R-esque ways of doing things, but the goal here is to get as close to one-to-one with methodology and output.
- VCASMO – Web Development with R – Presentations given at the Bay Area useR Group on January 10, 2010 by Jeroen Ooms, on how to create web applications use R.
