An Engineer's Guide to Bandwidth (Yahoo! Developer Network Blog)
by karlcow
& 1 other
Web app developers spend most of our time not thinking about how data is actually transmitted through the bowels of the network stack. Abstractions at the application layer let us pretend that networks read and write whole messages as smooth streams of bytes. Generally this is a good thing. But knowing what's going underneath is crucial to performance tuning and application design. The character of our users' internet connections is changing and some of the rules of thumb we rely on may need to be revised.
Création d'applications Web sans Web Forms
by ms_michel
Quand j'ai commencé à créer des applications Web plus sophistiquées, les abstractions offertes par Web Forms, comme les contrôles, l'état d'affichage et le cycle de vie de page, ont commencé à m'irriter au lieu de m'aider.

Yahoo!’s spatial thinking at Tim Warr’s Blog
by karlcow
or woeid is a universal cultural mapping system. The meaning is carried by people, not mathematics abstractions.So what I love about WOE ID is it is a simple non mapping solution to an age old spatial problem. In fact a map is ultimately relegated to just a display function.
Wireless in the world
by karlcow
Using simple abstractions such as the dashed line and the kinds of visual language that we have previously proposed for RFID allow us to quickly communicate aspects such as the spatial properties of wireless technologies that are often overlooked. I’ve been using these images in presentations for a while, to sensitise designers and students to the spatial and embodied properties of RFID, Bluetooth and WIFI.

DeepLearningWorkshopNIPS2007 < Public < TWiki

Theoretical results strongly suggest that in order to learn the kind of complicated functions that can represent high-level abstractions (e.g. in vision, language, and other AI-level tasks), one may need "deep architectures", which are composed of multiple levels of non-linear operations (such as in neural nets with many hidden layers). Searching the parameter space of deep architectures is a difficult optimization task, but learning algorithms (e.g. Deep Belief Networks) have recently been proposed to tackle this problem with notable success, beating the state-of-the-art in certain areas.
This workshop is intended to bring together researchers interested in the question of deep learning in order to review the current algorithms' principles and successes, but also to identify the challenges, and to formulate promising directions of investigation. Besides the algorithms themselves, there are many fundamental questions that need to be addressed: What would be a good formalization of deep learning? What new ideas could be exploited to make further inroads to that difficult optimization problem? What makes a good high-level representation or abstraction? What type of problem is deep learning appropriate for?
The workshop presentation page show selected links to relevant papers (PDF) on the topic.

The value of this architecture is that each layer leverages the social components of the lower layer's architecture.

Practical Semantic Astronomy*
by karlcow
oooooh!Semantic Web has become a set of practical engineering challenges, more concerned with deployment and performance details than AI abstractions, and so we can now start to employ that community's more successful ideas in astronomy

What is Enlightenment?
Enlightenment. What is Enlightenment?.
Some people affectionately refer to Enlightenment as E because typing or saying the whole word is a bit of a mouthful. Early in its history, which began back in 1996, E was just a window manager for X11.
Since then, E has now become much more. In the process of building the next generation of the window manager, we have created a suite of libraries for doing data storage and retrieval, scene-graph rendering with a canvas, theme encapsulation, compiling and demand-loading, event loop, inter-process communication, freedesktop.org specification handling, virtual machines, video codec abstractions, widget sets, and more.

Web Frameworks for Python
A Web framework is a collection of packages or modules which allow developers to write Web applications (see WebApplications) or services without having to handle such low-level details as protocols, sockets or process/thread management. As a developer using a framework, you typically write code which conforms to some kind of conventions, with the benefit being that most of the code can be concerned with the logic of the application, rather than working out how to process incoming network messages, spawn processes, work out which part of the application should be invoked, and so on.
Some frameworks can be considered moderately low-level in that they provide abstractions only for certain things (eg. incoming requests, outgoing responses, state handling), whereas other frameworks provide many more abstractions and mechanisms (eg. database access, presentation of Web pages). Since a non-trivial Web application will require a number of different kinds of abstractions, often stacked upon each other, those frameworks which attempt to provide a complete solution for applications are often known as "full-stack" frameworks in that they attempt to supply components for each layer in the stack
Alien Art
by hanso
Conceptual artist Jonathan Keats has revisited a transmission from space (named SHGb02+14a) once thought by some hopefuls to originate from an alien intelligence. By applying specific rule sets to the information, he has produced several visual abstractions that he considers art. The exhibit opened on Monday in Berkeley.
The Boost Graph Library
by YukuanMark
Graphs are mathematical abstractions that are useful for solving many types of problems in computer science. Consequently, these abstractions must also be represented in computer programs. A standardized generic interface for traversing graphs is of utmos
Internet-Draft : "duri" and "tdb" URN namespaces based on dated URIs - L. Masinter, Adobe Systems - April 17, 2004 - Expires: October 16, 2004
by digitalmonkey
"The first namespace ("duri") is used to refer to URI-identified resources as they appeared at a particular time. The second namespace ("tdb") is useful as a way of creating URNs that refer to physical objects or even abstractions that are not themselves

Tomgram: Elizabeth de la Vega on Shooting the Moon in 2006

While masquerading as hard-headed realists, the President and war hawks from both parties have been, at best, determined illusionists. They have shrouded the war in abstractions...all of which are, ultimately, obscene.
Art auto-génératif
by letawny
Je viens d'ajouter à l'instant quelques réalisations dans la galerie Abstractions des Missi[v/l]es virtuelles.Le Real Time Contextual Art GeneratorCertaines sont les fruits d'expérimentations faites avec le Real Time Contextual Art Generator de Don Relyea, qui se présente sous deux formes : un exécutable à télécharger ou une application en ligne, qui nécessite le plugin Shockwave. Dans les deux cas, l'utilisateur saisit un ou plusieurs mots-clefs, l'application récolte, dans la base de données de Google, nombre d'images liées à la requête et génère une image stylisée et composite, comme celle-ci :Préférez le programme à télécharger, car il est paramétrable, contrairement à la version en ligne. On peut ainsi régler le degré de transparence des layers, activer ou non le mode loop, contrôler les polices utilisées pour les textes, définir la résolution des images générées, etc. Il offre en outre la possibilité d'exporter le résultat au format *.jpg.Pendant que vous y êtes, rendez-vous sur cette page, pour voir une démonstration du Hilbert Hardcore, qui exploite l'algorithme de David Hilbert, mathématicien allemand qui découvrit la courbe qui porte son nom au début du XIXème siècle :Jetez aussi un coup d'oeil à la variante, le Hilbert Hardcore Helipad, ainsi qu'au générateur expérimental qui dessine ces luxuriantes fleurs :Le générateur Net.ArtLes autres images de la galerie Abstractions des Missi[v/l]es ont été créées avec le Net.art generator, qui repose sur le même principe que le RTCAG, décrit ci-dessus : un mot-clef, qui correspond au titre de l'image à générer, une recherche contextuelle dans Google et l'image composite obtenue. A noter toutefois, quelques différences dans le protocole :l'utilisateur peut choisir la taille (400, 600, 800 ou 1000px) et le format (*.jpg, *.gif, *.png) de l'image généréeil choisit le nombre d'images à utiliser : 2, 4, 6, 8il a accès aux images d'origine utilisées dans le montageUne galerie des meilleurs collages générés est disponible, mais voici un échantillon de mon exploration :
Representational State Transfer - Wikipedia, the free encyclopedia
by fredbird
& 6 others
Representational State Transfer (REST) is a collection of principles for managing information over a computer network like the world wide web.
While REST originally referred to a collection of architectural principles (described below), people now often use the term in a looser sense to describe any simple web-based interface that uses XML and HTTP without the extra abstractions of RPC-based approaches like the web services SOAP protocol.
