Helping dev teams adopt new technologies & practices || InfoQ, QCon
I’ve always felt a little uncomfortable when people use terms like “best practises” or “industry standards”, and this post is about a real world example of why everyone should be cautious of such claims.

“With the W3C working on a specification that defines an API for providing scripted access to geographical location information, Mozilla recently announced built-in Geolocation support for Firefox 3.5. This is aligned with an earlier announcement from Opera that also adds support for Geolocation in their browser. Will this make geographically aware applications ubiquitous?”

“HTML 5 is the fifth major revision of the core language of the World Wide Web and although the specification is ongoing work, parts of HTML 5 are already implemented in browsers like Safari 4 beta.
In addition to specifying markup, HTML 5 exposes several new scripting APIs for:
InfoQ recently conducted a virtual panel via email regarding how the JavaScript frameworks will evolve in order to take advantage of these new APIs. The panel featured representatives from some of the most widely deployed projects that deal with client-side JavaScript:

“John Resig creator of the jQuery JavaScript library, has released Test Swarm, a platform for distributed continuous integration testing for client-side JavaScript. Frustrated with traditional JavaScript testing environments that don’t scale, John’s new project which is currently is private alpha, aims to provide a systems for outsourcing browser related testing to large groups of people or communities.”

“Last week Mozilla released Bespin, a web-based framework for code editing and only a few days later Boris Bokowski and Simon Kaegi implemented an Eclipse-based Bespin server using headless Eclipse plug-ins. With the presentation of a web-based workbench at EclipseCon and the release of products like the Heroku web-based IDE for RoR apps, it seems that web-based IDEs might soon become mainstream.”

Reading a friends blog post, I found out about a challenge for making a web app in 140 characters or less.
In Wikipedia you read:
In software engineering, a web application or webapp is an application that is accessed via web browser over a network such as the Internet or an intranet. It is also a computer software application that is coded in a browser-supported language (such as HTML, JavaScript, Java, etc.) and reliant on a common web browser to render the application executable.
So this is what I could come up with: just paste the following piece of code (140 characters) in a file with a .html extension, open it with a browser and you have a crude number guessing game:
<script>function
x(){if(confirm("odd?")&&((Math.floor(Math.random()*10))%2))alert(":)");else
alert(":(");if(confirm("rpt?"))x()}x()</script>
The browser calculates a random integer and asks you if it is an odd numbers. If your answer is correct it returns a smiley (or a frown if you’ve guessed wrong). Finally it asks you if you want to repeat the game and if you choose “ok” the whole thing starts over again.
You can save many characters by omitting the loop. Also you can save 10 whole characters by having the browser randomly choose “1” or “0” and asks you to guess between them.
<script>function x(){if(confirm(“1?”)&&(Math.round(Math.random())))alert(“:)”);else alert(“:(“);if(confirm(“rpt?”))x()}x()</script>

“The public draft of the Java EE 6 Platform specification has been published and will remain open for public review and feedback until the 23rd of Feb, 2009. Maybe the most notable part of this delayed draft is the Web Profile, which is first profile in the history of the Java EE platform.”

I think snitch.name does pretty well 🙂
“With JDK7, OpenJDK and IcedTea all evolving in parallel it can get confusing about how these projects relate to each other. David Herron, which is OpenJDK Quality Lead, tries to set the record straight and explains why the JDK7 has taken so long.”

snitch.name was originally a tool I developed because I was tired of having to search in various place to find information about someone I met. It hasn’t been designed to be fancy, but solves a real world problem until the people that build social services decide on some profile searching APIs. Until that time comes snitch.name is the best tool for searching for people’s profiles on social services.
I’ll try to incorporate more user requested features, so drop me a line if you’d like to have a new search provider added or have some new functionality in mind.
You can search with snitch.name directly from your browser’s search box using the OpenSearch specification! This is the box that sits right from your address bar. Both IE7 and Firefox support it
Do I need an account on these social sites?
In most cases these sites reveal little or no information to users that don’t have an account so it would be wise to get an account. It is free anyway 🙂
Why can’t I just use Google?
There are several advantages over a plain Google search! Some of them are:
Why everything loads inside the browser?
This way you access the social sites using your own credential and get authorized for the maximum amount of information you are allowed to. Many social sites don’t have public/open APIs (eg. LinkedIn) and even the ones that do have would need you to authenticate again. This could be very impractical. With snitch.name the cookies you have stored in your browser already do all the work to authenticate you.
Is it better than other people-search-services?
Try yourself to see how superior snitch.name is!
Many thanks to Christos Stathis, Fotis Stamatlopoulos, Kostas Troulos & Panagiotis Astithas, for their early feedback.
“During Devoxx Mark Reinhold, Chief Engineer for Java SE, gave a presentation about the latest directions for Java 7, alongside a release date in early 2010. Although Mark described his presentation as a provisional plan and not binding, there have been many reactions from the community, especially regarding the omission of Closures.”

“JSR-315 has produced a Public Review (PR) of the Servlet 3.0 specification, accompanied by a reference implementation in the GlassFish trunk. This release has resulted in a debate around the choices that the Expert Group (EG) has taken for the next generation Servlet APIs and the whole of the Java EE 6 platform.”

“Though Comet and Ajax can both deliver end-user experiences that provide desktop-like functionality and low user-perceived latency, only Web Sockets lives up to the promise of providing a native means to accurately and efficiently stream events to and from the browser with negligible latency. It is by far the most comprehensive solution for delivering real-time information over the Web. Not only does it provide full asynchronous duplex streaming communication with a single TCP/IP connection, but also benefits from few HTTP headers and more importantly allows the same message format to be used by both the browser and the origin service.”
