Donderdag is versie 10.60 van de webbrowser Opera uitgekomen. Opera is van Noorse makelij en heeft browsers voor alle belangrijke computer- en een groot aantal mobiele platforms. De browser biedt tabs, kan worden aangestuurd met mouse gestures, heeft een ingebakken downloadmanager en biedt bescherming tegen phishing en malware. Naast surfen kan er met Opera ook worden gemaild, is er een ingebouwde BitTorrent-client en kan er worden gechat via irc of het door Opera zelf ontwikkelde sociale netwerk Unite. Versie 10.60 maakt gebruik van versie 2.6 van de rendering engine Presto, wat de snelheid en stabiliteit ten goede is gekomen en bovendien de deur opent naar nieuwe mogelijkheden, waaronder geolocation en off-line webapplicaties.
Opera Presto 2.6 rendering engineGeolocation services
- Opera 10.60 final contains the Opera Presto 2.6 rendering engine, which improves stability and adds support for the following new Opera features.
Offline Web Applications
- User-enabled geolocation services are provided through Google Location Services (GLS).
- IP address and WiFi recognition are implemented.
- IP address recognition works with GLS by recognizing your IP address and telling you the cordinates based on it.
- WiFi recognition works with GLS by gathering and then sending a list of all nearby wireless networks including MAC (Media Access Control) address, SSID (Service set identifier) name, and signal strength, which returns your coordinates.
- An address bar map pin icon indicates a Web page is accessing the Geolocation API.
- Opera geolocation services support the W3C Geolocation API Specification
- A user decides to share or not share their device location with a Web site based on trust; see section 4.2 of the W3C Geolocation specification.
- Further information is available at the Opera Desktop Team blog: "The return of Geolocation"
- See this Opera demo
Web Workers
- Support is added for Offline Web Applications implementing the user interface for caching.
- This allows documents to communicate with each other regardless of their source domain, and is designed in a way which does not enable cross-site scripting attacks.
- See this Opera demo
WebM
- Web Workers is an API for running scripts in the background independently of any user interface scripts. This allows for long-running scripts that are not interrupted by scripts that respond to clicks or other user interactions, and allows long tasks to be executed without yielding to keep the page responsive.
- See this Opera demo
- The WebM format consists of the VP8 video and Vorbis audio codecs wrapped inside a .webm container. It is based on the Matroska media container format, and offers high-quality video with fast seeking.
- WebM works together with the HTML5
<video>element supported in the Opera Presto rendering engine.- See these Opera articles:
