USB pendrive-ba rejtett dual-core számítógép Androiddal 

Cotton Candy névre hallgat az az érdekes hardver, amelyet a norvég FXI technologies mutatott be nemrég. Egy USB pendrive méretű készülékről van szó, amelynek mindkét végén csatlakozó található. A cég a következőképpen reklámozza: “dual-core számítógépet rejtő USB stick, amely bármelyik kijelzőt Android állomássá változtatja”.

A cég szerint az eszközt rádughatjuk akár asztali számítógépre, laptopra, (megfelelő) TV-re, set-top box-ra, USB hub-ra stb. azokból androidos rendszert csinál. A mindössze 21 grammos eszközben kétmagos 1,2GHz-es ARM processzor, 802.11n Wi-Fi, Bluetooth, HDMI-out és microSD kártya slot található. A prototípus Android 2.3-at futtat, de a cég képviselője szerint képesek jelenleg Ubuntu-t is futtatni, valamint a jövőbeli verziókon akár Windows 8 futhat majd.


Keresőt fejlesztettek az iPhone agyára 

Képeskönyvként tárja a felhasználó elé a beírt témához kapcsolódó legjobb cikekket a Trap.it nevű új kereső. A tartalmakat nem emberek vagy szorgos keresőrobotok válogatják össze, hanem az iPhone 4S hangvezérléses rendszerének agyából ismert mesterséges intelligencia.

Selenium 2 Screen Capture C# & Java 

Selenium 2 has come up with some great new functionality that makes website testing much easier. This is because of the webdriver architecture allows interaction outside of javascript sandbox. That means if you have a quirky browser implemnentation of javascript and you had to shoe horn your scripts, you don’t have to do that so much anymore.
Selenium works within a testing framework so it reports back if your assertions pass or not. The one additional thing QA folks like is to see if the page rendered ok. Just because an element rendered on a page doesn’t mean it was placed in the correct spot, because of image pixal spacing. The often used technique is to capture a screenshot of the page. This can be when a test
passes or maybe even when a test fails.
Selenium WebDriver makes this process easy both for a webdriver running remotely via selenium hub or locally.

JavaFX may be the next Adobe AIR 

I already wrote a post about JavaFX embracing HTML+CSS. Let’s add also Oracle could offer with JavaFX the next Adobe AIR, as these 2 platforms are closer and closer. Let’s detail this point here:
– JavaFX is Java-based, while AIR is ActionScript-based, but both languages are close (see this post)
– WebKit is integrated into both platforms
– JavaFX has now the possibility, like AIR, to define views through an XML-based language called FXML
– Both runtimes sit outside the browser
– Both are expected to be open source

Getting Started with FXML

FXML is new for JavaFX 2.0, and you might ask “What is FXML?” and “Is FXML for me?” FXML is an XML-based declarative markup language for defining the user interface in a JavaFX application. FXML is well-suited for defining static layout such as forms, controls, and tables. With FXML, you can also construct layouts dynamically by including a script.

JQuery Mobile 1.0 Released, Gets Mixed Reaction 

JQuery Mobile 1.0 has been released and is available for download. The framework built on JQuery and JQuery UI supports all major mobile, tablet, e-reader and even desktop platforms. Using tools like PhoneGap, you can even transform JQuery Mobile code into hybrid or native apps that can be distributed through all popular app stores. By Roopesh Shenoy

Why you have less than a second to deliver exceptional performance 

The success of the Web performance movement shows that there is increasing interest and value in fast websites. That faster websites lead to more revenue and reduced costs is a well proven fact today. So being exceptionally fast is becoming the dogma for developing web applications. But what is exceptionally fast and how hard is it to build a top performing web site?

Speeding up Android development with Android-x86 and VirtualBox

I’m starting to learn how to develop to Android and so far to me the only downside of the whole dev environment is the painfully slow Android Emulator. Don’t get me wrong, it’s such a beautifully made emulator that covers most (if not all) details of a real device, I specially like tricks such as limiting network bandwidth to simulate your app under a slow connection, but let’s face it, the thing is slow.

First Look: Oracle NoSQL Database 

InfoWorld’s Peter Wayner takes a first look at Oracle NoSQL Database, the company’s take on the distributed key-value data store for the enterprise. ‘There are dozens of small ways in which the tool is more thorough and sophisticated than the simpler NoSQL projects. You get a number of different options for increasing the durability in the face of a node crash or trading that durability for speed,’ Wayner writes. ‘Oracle NoSQL might not offer the heady fun and “just build it” experimentation of many of the pure open source NoSQL projects, but that’s not really its role. Oracle borrowed the best ideas from these groups and built something that will deliver good performance to the sweet spot of the enterprise market.’
