Apache Hadoop 大笨象

http://hadoop.apache.org/

What Is Hadoop?

The Apache Hadoop project develops open-source software for reliable, scalable, distributed computing, including:

* Hadoop Core, our flagship sub-project, provides a distributed filesystem (HDFS) and support for the MapReduce distributed computing metaphor.

* HBase builds on Hadoop Core to provide a scalable, distributed database.

* Pig is a high-level data-flow language and execution framework for parallel computation. It is built on top of Hadoop Core.

* ZooKeeper is a highly available and reliable coordination system. Distributed applications use ZooKeeper to store and mediate updates for critical shared state.

* Hive is a data warehouse infrastructure built on Hadoop Core that provides data summarization, adhoc querying and analysis of datasets.

柏楊曰:

在〈司馬光曰〉中，可以充份看出司馬光 的意識形態，他有一種
崇古的狂熱，和一種 維持現狀的 固執。

司馬光 是一位正統的儒家學派學者，竭力反對 古代所沒有的任何東西
，和任何 改革現狀 的措施。

司馬光 這位儒家學派大師，所代表的儒家思想中，沒有民主觀念，更
沒有人權觀念，只有強烈的 維護既得利益階層的 奴性。

他要求的是，平民必須安於被統治的現狀。等級 不可改變，名份 不可改變；君王 永遠是君王，平民永遠是平民，夾在當中的司馬光 所屬的以做官為唯一職業的 知識份子──士大夫階層，永遠 是士大夫。

R--Language for Statistical Computing

R--Language for Statistical Computing

R 語言是主要用於統計分析、繪圖的語言和 操作環境。

R 內建多種 統計學及 數字分析功能。R 的功能也可以透過安裝套件（Packages，用戶撰寫的功能）增強。因為S的血緣，R 比其他統計學或 數學專用的 編程語言有更強的 物件導向(面向物件程式設計)功能。

R 的另一強項是繪圖功能，製圖具有印刷的質素，也可加入數學符號。

雖然R 主要用於 統計分析或者開發統計相關的軟體，但也有人用作 矩陣計算。其分析速度可比美 GNU Octave甚至 商業軟件 MATLAB。
