GeoAPI services include a reverse geocoder; deep data about 16 million businesses and tens of thousands of points of interest; a writable layer for developers to annotate the world and do complex geo-queries; and location-enabled media layers (e.g., Twitter and Flickr). We've also recently added an iPhone SDK to speed up mobile development.
The DB layer should return objects that are easy to cache and easy to invalidate. The built-in Django database classes (combined with memcache) should work fine for us here.
Today we'd like to share with the web community information about SPDY, pronounced "SPeeDY", an early-stage research project that is part of our effort to make the web faster. SPDY is at its core an application-layer protocol for transporting content over the web. It is designed specifically for minimizing latency through features such as multiplexed streams, request prioritization and HTTP header compression.
The Social service enables you to write applications that integrate leading social networks such as Facebook and MySpace into your apps. The service, implemented through an easy to use API, provides an abstraction layer that connects with different networks. This removes the complexity and repetitive work of having to implement multiple APIs in order to integrate social features from multiple social networks into your application.
Creating Offline Web Applications With Dojo Offline by Brad Neuberg (SitePen), September 23rd, 2007 This tutorial steps you through creating offline web applications using Dojo Offline. What is Dojo Offline? Dojo Offline is an open-source toolkit that makes it easy to create sophisticated, offline web applications. It sits on top of Google Gears, a plugin from Google that helps extend web browsers with new functionality. Dojo Offline makes working with Google Gears easier; extends it with important functionality; creates a higher-level API than Google Gears provides; and exposes developer productivity features. In particular, Dojo Offline provides the following functionality: An offline widget that you can easily embed in your web page with just a few lines of code, automatically providing the user with network feedback, sync messages, offline instructions, and more A sync framework to help you store actions done while offline and sync them with a server once back on the network Automatic network and application-availability detection to determine when your application is on- or off-line so that you can take appropriate action A slurp() method that automatically scans the page and figures out all the resources that you need offline, including images, stylesheets, scripts, etc.; this is much easier than having to manually maintain which resources should be available offline, especially during development. Dojo Storage, an easy to use hashtable abstraction for storing offline data for when you don't need the heaviness of Google Gear's SQL abstraction; under the covers Dojo Storage saves its data into Google Gears Dojo SQL, an easy to use SQL layer that executes SQL statements and returns them as ordinary JavaScript objects New ENCRYPT() and DECRYPT() SQL keywords that you can mix in when using Dojo SQL, to get transparent cryptography for columns of data. Cryptography is done on a Google Worker Pool thread, so that the browser UI is responsive. Integration with the rest of Dojo, such as the Dojo Event system
There has been quite a bit of talk lately about the best way to secure a domain, mainly centered in two camps: using Secure Socket Layer (SSL), or using DNS Security Extensions (DNSSEC). The answer is quite simple—you should use both.
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.
]]>A browser within your browser. siteFlow is a cross-browser tool that enables you to browse multiple pages (i.e those featuring next/previous buttons, like Google’s search results) and archived web content, faster and with less effort than the usual one-page-at-once browsing. It adds an extra layer of interactivity (literally and figuratively) on top of web pages. Turbocharge your web reading.
In this Photoshop tutorial, we'll learn how to create a high key glow effect, which is a fancy way of saying we'll be applying a glow only to the highlights in an image. This effect works especially well with wedding portraits since it's great for adding a romantic, magical look to your photos, and wedding portraits usually contain lots of bright white areas to work with. We'll see how to easily select just the highlights in an image using Photoshop's Color Range command, then we'll copy the highlights to their own layer and create the glow effect using a blur filter and one of Photoshop's layer blend modes designed for lightening images. Finally, we'll combine layers into a layer group and use a layer mask to limit the areas where the glow effect is visibile. It may sound like a lot of work, but once you know how to do it, the entire effect can be completed in just a few minutes! I'm using Photoshop CS4 here, but any recent version of Photoshop will work.
ShiftSpace (pronounced: §) is an open source browser plugin for collaboratively annotating, editing and shifting the web.Annotate, hightlight, swap images, edit pages with a group

Scala Migrations is a library to manage upgrades and rollbacks to database schemas. Migrations allow a source control system to manage together the database schema and the code using the schema. It is designed to allow multiple developers working on a project with a database backend to design schema modifications independently, apply the migrations to their local database for debugging and when complete, check them into a source control system to manage as one manages normal source code. Other developers then check out the new migrations and apply them to their local database. Finally, the migrations are used to migrate the production databases to the latest schema version. The Scala Migrations library is written in Scala and makes use of the clean Scala language to write easy to understand migrations, which are also written in Scala. Scala Migrations provides a database abstraction layer that allows migrations to target any supported database vendor.
Elixir is a declarative layer on top of the SQLAlchemy library. It is a fairly thin wrapper, which provides the ability to create simple Python classes that map directly to relational database tables (this pattern is often referred to as the Active Record design pattern), providing many of the benefits of traditional databases without losing the convenience of Python objects.
Elixir is intended to replace the ActiveMapper SQLAlchemy extension, and the TurboEntity project but does not intend to replace SQLAlchemy's core features, and instead focuses on providing a simpler syntax for defining model objects when you do not need the full expressiveness of SQLAlchemy's manual mapper definitions.

The SFMoMA is all about creating a space for modern art to live. But there's also a meta-layer to the art experience that comes from the aesthetic and conceptual life of the space itself – the colors, the architecture, the little design touches. These elements contribute to our experience of the art inside, but often operate below our cognitive awareness. I decided to bring one of those meta-elements to the forefront of attention – the typography used inside the museum, on anything from exhibition signage to elevator buttons to restroom signs.
I've been experimenting with some javascript classes that mimic the structure of mapnik's Layer/Style/Rule classes and render OSM data (via GeoJSON) to a <canvas> element. I've also finally taken a look at how github works, so I've decided to share the initial code there in case people are interested. If you don't want to check the code out for yourself there's a demo page here (tested in Firefox and Safari only, so far).
I2P is an anonymizing network, offering a simple layer that identity-sensitive applications can use to securely communicate. All data is wrapped with several layers of encryption, and the network is both distributed and dynamic, with no trusted parties.
KDE on Cygwin is the port of Qt and KDE to Windows using Cygwin, the POSIX emulation layer for Windows, and the Cygwin XFree86 server. We think that KDE is a great desktop and has the opportunity to be a big player in the 'desktop environment' area. One of the main reasons for this is because of the famous Qt library, which is designed to be very platform independent and has already been ported to many operating systems. Hence porting KDE applications from one UNIX derived operating system to another is relatively painless. The one operating system this doesn't hold true for is Windows.
App Engine applications can be implemented using the Python programming language. The App Engine Python runtime environment includes a specialized version of the Python interpreter, the standard Python library, libraries and APIs for App Engine, and a standard interface to the web server layer.
Les avocats de Yahoo! détruisent beaucoup du potentiel créatif de ses employés, même chose pour ceux qui voulaient participer au W3C.But back to Flickr, I’ve often joked that I could probably get more stuff done working with the Flickr API outside of Flickr than inside. Mainly due to the simple removal of the Lawyers-Layer more than anything else ;)
