SPMF: A Java Open-Source Data Mining Library
Introduction SPMF is an open-source software and data mining library written in Java, specialized in pattern mining (the discovery of patterns in data) . It is distributed under the GPL v3 license. It offers implementations of 254 data mining algorithms for: association rule mining, itemset mining, sequential pattern sequential rule mining, sequence prediction, periodic pattern mining, episode min
Sux: Implementing Succinct Data Structures
Sux in an umbrella nickname for the results of my fiddling with the implementation of basic succinct data strucures. The resulting code is rather sparse. The main highlights are: a novel, broadword-based implementation of rank/select queries for up to 264 bits that is highly competitive with known 32-bit implementations on 64-bit architectures (additional space required is 25% for ranking and 12.
Netty: Home
Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. Netty is an NIO client server framework which enables quick and easy development of network applications such as protocol servers and clients. It greatly simplifies and streamlines network programming such as TCP and UDP socket server. 'Quick and ea

Tuning Java Garbage Collection for Web Services
Since I've been declared the local Java Garbage collection guru[1], I've found myself answering the same kinds of questions over and over. "Why am I getting frequent GC pauses?", "How do I avoid long GC pauses?", "Concurrent mode failure - how bad is that?" In the spirit of teaching people to fish, I thought I'd get together a blog post on how you (yes, you!) can tune the garbage collector for som
Javaメモリ、GCチューニングとそれにまつわるトラブル対応手順まとめ - 日記のような何か
GC周りでトラブルシューティングした際の経験や、Web等で調べたことをまとめてみる。 前提 ・JVMは、Sun Javaを想定。(他は使ったことないです。。。) ・Sun Java 1.5-1.6を想定。 目標 マイナーGC、Full GCそれぞれが頻発することなく、かつそれぞれの実行時間を1秒未満に抑えること。 マイナーGCは1秒未満どころではなく、もっと短くなるべき。どれくらいが理想かは？(0.1秒未満ぐらいを目指したい？) 連続した負荷状態(想定されるピークアクセス)でもOutOfMemoryErrorが発生しないこと。 理想的な状態は、上記に加えて、Full GCの発生が低頻度であること。 具体的には、できるだけマイナーGCで短命オブジェクト(1回使ったらもう使わないようなオブジェクト。逆にセッションオブジェクト等は長命オブジェクトとなる)を破棄させて、短命オブジェクトが、Tenu

What is an API (application programming interface)? Definition and examples A lot of people who work in technology have an intuitive understanding of what an API (application programming interface) is — but if you asked them to define it, they might have trouble putting an explanation into words. In simple terms, an API is both a piece of software running on a networked server and a component of p

google-guice - Google Code
Put simply, Guice alleviates the need for factories and the use of new in your Java code. Think of Guice's @Inject as the new new. You will still need to write factories in some cases, but your code will not depend directly on them. Your code will be easier to change, unit test and reuse in other contexts. Guice embraces Java's type safe nature. You might think of Guice as filling in missing featu
