PyGPU - Python for the GPU
PyGPU - Python for the GPU Haven't you ever dreamt of writing code in a very high level language and have that code execute at speeds rivaling that of lower-level languages? PyGPU is a compiler that lets you write image processing programs in Python that execute on the graphics processing unit (GPU) present in modern graphics cards. This enables image processing algorithms to take advantage of the

JavaSIFT
This example shows two consecutive TEM sections of the Drosophila first instar larval brain dataset by Albert Cardona aligned with the JavaSIFT ImageJ plugin. A lightweight SIFT-implementation for Java after the paper of David Lowe (2004). The ImageJ plugin can be used for aligning image stacks. Note, that the SIFT-algorithm is protected by U.S. Patent 6,711,293: Method and apparatus for identifyi
SIFT++
SIFT++ is a lightweight C++ implementation of SIFT detector and descriptor (it is derived directly from the MATLAB/C implementation). Usage The binary distribution contains a single executable file sift for each architecture (for instance, glx/sift for GNU/Linux). Due to linkage issues with the C++ ABI the provided binary could not work; in this case it is recommended to compile your own version o

Linuxmania: Linux Fedora8 32bit版で4GB以上のメモリを使う(Fedora,CentOS)
Linuxでは、PAE機能を有効にした kernel-PAE というカーネルで起動することで、32ビット版でも４GB以上のメモリを認識することができます。（同様に一部のWindows OSでも (Windows Server 2003など)、PAE機能を有効にして4GB以上のメモリを認識することができるようです） ※PAE (物理アドレス拡張) メモリアドレス空間を拡張することで、32ビットOSで大容量メモリを 認識可能にするインテル・アーキテクチャの機能です。 参考:物理アドレス拡張 - Wikipedia(外部リンク) 1.

Creating a Sustainable Future with Technology
In a world where digital communication continues to blur the lines between the personal and the impersonal, a quiet revolution is unfolding. Online greeting cards are transforming the way we connect with each other, breathing new life into the age-old tradition of personal correspondence. These digital expressions of thoughtfulness have expanded the horizon of how sentiments are shared, allowing f

第22回 大きなデータを眺める 2008年5月16日 IT コメント： トラックバック (0) （これまでの増井俊之の「界面潮流」はこちら) 下図はMacintoshの Disk Inventory X というソフトで私のホームディレクトリの中のファイルの大きさを視覚化したものです。 大きなファイルが大きな矩形で表現され、ファイルをまとめたフォルダも矩形として階層的に表現されています。 一方、下図はWindowsの SequoiaView というソフトを使ってファイルの大きさを視覚化した例です。 後発のDisk Inventory Xは、おそらく SequoiaView に触発されたと思われるので外見がよく似ていますが、階層的に配置した矩形の集合でファイルサイズを表現するという方法は、University of Maryland の Human-Computer Interaction
Metagold: A Research Blog about Nico Nico Douga
In the last post I have stated that random lists are boundary objects: They include a low level of list-ness, and can therefore often better be described as sets or groups (I used these two terms quite carelessly as interchangeable - I will stay with the term 'set'), which have a certain degree of list-ness. Now I want to look into this a bit more thoroughly. To look at boundary objects such as ra
Threadpool
Warning This module is OBSOLETE and is only provided on PyPI to support old projects that still use it. Please DO NOT USE IT FOR NEW PROJECTS! Use modern alternatives like the multiprocessing module in the standard library or even an asynchroneous approach with asyncio. Description A thread pool is an object that maintains a pool of worker threads to perform time consuming operations in parallel.
[Saq.] ARToolKit を Flash に移植したよ。
こんちわ。さくーしゃです。 えーと、巷では Flash Player 10 beta で騒がしい感じになってきておりますが、そんな中、わたくしは ARToolKit を Flash (AS3) に移植してました。FLARToolKit と命名しておきましょう。まー、移植つっても本家からじゃなくって A虎@nyatla.jp 氏が Java に移植した NyARToolkit を AS3 で書き直したものなんだけど。言語仕様が近いだけあって C 版よりもはるかに移植しやすかったですな。 やっぱでもねー、速度的にはかなり厳しいもんがあるな。ラベリングの部分は Bitmap 師匠のコードをベースにほとんど書き直したんだけど、それでも複数マーカーの認識とかってのはかなり無理がありそう。 3D 表示部分も現状の Flash だとソフトウェアレンダリング（デモでは Papervision3D 使ってる

Bad CTK » Blog Archive » Python: Tips For Writing Daemons
Here’s some useful information for writing daemons in Python. One common problem that people run into is os.fork() producing zombie processes when children quit. This can easily be overcome by setting the SIGCHLD signal to SIG_IGN. ie: import signal signal.signal(signal.SIGCHLD, signal.SIG_IGN) On some flavors of Unix, you are forced to do a double-fork on startup, in order to go into daemon mode.

Collective Intelligence in Action
There's a great deal of wisdom in a crowd, but how do you listen to a thousand people talking at once? Identifying the wants, needs, and knowledge of internet users can be like listening to a mob. In the Web 2.0 era, leveraging the collective power of user contributions, interactions, and feedback is the key to market dominance. A new category of powerful programming techniques lets you discover t

How to record RTMP flash video streams using Red5
Update 2009-04-04: I’ve released an open source project that you can use to download RTMP video streams in a much simpler way. You can find it here: http://flazr.com Red5 is an open source Flash server written in Java. It does not include a standalone client yet but I was able to write a Java program that uses Red5 to connect to an RTMP video stream and record / save it to a file. Code is provided
