WebSphere Portal Family wiki: Developing an Exceptional Web Experience: Leveraging Reverse AJAX in IBM WebSphere Portal 7.0 using Dojo CometD and Web messaging service

The Reverse Asynchronous JavaTM and XML (AJAX) technology enables dynamic content to be delivered to the browser, thus improving application performance by eliminating the need for constant polling. This technology can be used in many scenarios to deliver an excellent user experience. For example, a news portal can push the news to a user’s browser when it becomes available, without needing user action and without needing to keep refreshing or re-rendering the whole page. Another scenario is to display an up-to-date task list to which the server pushes the new task once it is created, so that the task owner doesn’t need to keep pulling the updates. In this article we go through all the steps needed to leverage Reverse AJAX in portlets using Dojo CometD implementation. We develop a Task List portlet that displays a set of tasks assigned to the logged-in user and to which the server keeps pushing any new tasks, using reverse AJAX.

Ruling Stands: Defendant Must Decrypt Laptop | Threat Level | Wired.com

A federal appeals court is rejecting an appeal from a bank-fraud defendant who has been ordered to decrypt her laptop so its contents can be used in her criminal case. Colorado federal authorities seized the encrypted Toshiba laptop from defendant Ramona Fricosu in 2010 with valid court warrants while investigating alleged mortgage fraud, and demanded she decrypt it by typing in her password. In January, U.S. District Judge Robert Blackburn ordered the woman, who faces decades in prison if convicted, to decrypt the laptop by the end of February. Her attorney appealed, hoping to win a reprieve based on the assertion that being forced to decrypt her laptop amounts to a breach of the woman’s Fifth Amendment right against compelled self-incrimination.

Ein Aussteiger aus der Fefes Blogredaktion packt aus - Pastebin.com

Nach all den Diskussionen um die journalistischen und ethischen Standards bei Fefes Blog möchte ich nun an die Öffentlichkeit treten und einen lange unbeachteten Punkt in den Diskurs werfen: die Arbeitsbedingungen in der Redaktion von Fefes Blog. Unter vorgehaltener Hand werden diese oft mit denen der Arbeiterinnen und Arbeiter und Transgender-Berufstätigen bei FoxConn verglichen: Unter unwürdigen Umständen müssen die Schreiberlinge mit einem menschenfeindlichen Zeitdruck klarkommen, selbständig CMS ohne jegliche GUI bedienen und die Zumutungen eines cholerischen Chefs ertragen. Die im Webteam beschäftigten Arbeiter mussten in mühevoller monatelanger Kleinarbeit XSLT-Filter schreiben, um jegliche Spuren des 150 Server starken verteilten Echtzeit-Java- und php-Backends zu vertuschen, außerdem Randgruppen-Browser für die Inkompatibilitätstests benutzen und Markov-Ketten-Generatoren für Füllabsätze trainieren.

Stop paying your jQuery tax

We spend an inordinate amount of time shaving 10% off our backend time but often forget the golden rule, in general the largest bottleneck is your front end. We should not feel powerless to attack the front end performance issues and can do quite a lot to improve JavaScript bottlenecks and perceived user performance.

Bei einem Jahresumsatz von 31,4 Milliarden € erlöst Amazon 995,7 € pro Sekunde. Die Verkaufsschlager waren die Kindle-Lesegeräte und das neue Amazon Tablet Kindle Fire. Das Tablet habe sich laut Konzernchef Bezos „sowohl in den USA als auch in Europa“ hervorragend verkauft. Das Wachstum des vergangenen Jahres ging allerdings auf Kosten des Gewinns, der um beinahe die Hälfte eingebrochen ist.
