Such customizations usually define variants, with a common code base and well documented variabil- which features are offered by the components, and may depend ity [1, 6, 19]. Modern software systems are often built as complex on backend components being configured in a specific way. As assemblages of customizable components that out-grow the expres- such system become very large, with a huge number of possible siveness of SPLs.

  • The State of KHTML in the Beginning
    The State of KHTML In The Beginning... Why KHTML Is Important ● KHTML is critical to the success of KDE ● Provides a fast, light web browser and component that tightly integrates with KDE ● Gives us higher visibility as a project: “the web” is much larger than the Linux desktop community ● It's a great testcase for our existing infrastructure What We Have ● CSS 1 / 2 parts of 3 ● Java applets (modular) ● SSL ● ECMAScript 1.2 ● Wallet ● XHTML ● KDE integration ● HTML up to 4.x ● Basic LiveConnect ● “AJAX” support ● KJSEmbed derived ● NS plugin support from KJS What We Don't Have ● Internal SVG support ● DOM bindings to non- C++/non-JS ● Latest NSPlugin API support ● Opacity (Qt4 should help) ● XBL ● Lightweight widgets ● Content Editable KHTML – From Industry ● Great alternative to Gecko and Opera – small, fast, easy to understand, standards compliant ● In use in many embedded platforms as well as desktop browsers – Safari, Nokia, Omni, etc ● Forking is a problem ● Gaining respect from other browser vendors ● Could become a major player with enough 'unity' - >= 10% market share Can We Complete The “Merge”? ● “Merging” is not really feasible at this point ● Unity – a port of WebKit to Qt4: – KPart, KIO development is underway – Ca n co-exist with KHTML from KDE – Works 'now' – Abstraction layer in WebKit makes it relatively easy to port – Open questions: How do we avoid re-forking? How do we merge our own work? If We Go Unity, What Do We Gain? ● Support for many of the functions we lack as described earlier – XBL, content editable, etc ●

    2 Contents 1 Glossary 4 3 1 Glossary Technologies Akonadi The data storage access mechanism for all PIM (Personal Information Manager) data in KDE SC 4. One single storage and retrieval system allows efficiency and extensibility not possible under KDE 3, where each PIM component had its own system. Note that use of Akonadi does not change data storage formats (vcard, iCalendar, mbox, maildir etc.) - it just provides a new way of accessing and updating the data.</p><p> The main reasons for design and development of Akonadi are of technical nature, e.g. having a unique way to ac- cess PIM-data (contacts, calendars, emails..) from different applications (e.g. KMail, KWord etc.), thus eliminating the need to write similar code here and there.</p><p> Another goal is to de-couple GUI applications like KMail from the direct access to external resources like mail-servers - which was a major reason for bug-reports/wishes with regard to perfor- mance/responsiveness in the past.</p><p> More info:</p><p> <a href=https://community.kde.org/KDE_PIM/Akonadi target=_top>Akonadi for KDE’s PIM</a></p><p> <a href=https://en.wikipedia.org/wiki/Akonadi target=_top>Wikipedia: Akonadi</a></p><p> <a href=https://techbase.kde.org/KDE_PIM/Akonadi target=_top>Techbase - Akonadi</a> See Also "GUI".
