Heise Developer: GoingNative 2012 — Gegenwart und Zukunft von C++

For you German speakers out there, my sixth Heise Developer article, “GoingNative 2012 — Gegenwart und Zukunft von C++” just went live on Heise’s site.

It’s a sum-up of the GoingNative 2012 conference that happened on Feb 2nd-3rd. There won’t be an English translation later, since it’d be outdated by the time it appeared. The talks are in English, and you can download them all from Microsoft’s Channel9 page, though.

From the article:

Die Qualität der Vorträge war durchweg hoch, wenn auch Nichtmuttersprachler einigen Vortragenden nur schwer folgen konnten. Die Konferenz macht Lust auf ein Jahr mit mehr C++-Konferenzen als seit 1999 üblich. Besonders hängen blieben das Versprechen auf schnelle Adoption des neuen Standards, auch von Clang und Microsoft, und der Versuch, die C++-Standardbibliothek in den nächsten Jahren massiv zu erweitern.

GoingNative12 @ KDAB, Berlin

For everyone interested in C++11, and as suggested by Herb Sutter, KDAB will show the live stream of the GoingNative12 C++ conference in it’s training facilities at Tempelhofer Ufer 11 in Berlin this Thursday and Friday (Feb 2nd and 3rd). The show is scheduled to run from 18:30 to 02:15 (CET) each day. We invite everyone to join us, but please drop us a note at berlin(at)kdab.com so we can plan ahead.

Wild Beasts

In “Private Practice: Taming Templates”, I had (deliberately, of course :)) hidden a bug in the implementation of KDGenericFactory. I’ve now added a discussion about the bug and its fix.

Private Practice: What’s in a Proxy-Style?

A new session in the private practice, “What’s in a Proxy Style?”, examines QProxyStyle and derives some important caveat when applying a classical Design Pattern.

This is the original-language version of my recent Mythos Proxy-Style article.

Private Practice: Taming Templates

I’ve started a new column, Private Practice, that looks at existing implementations and examines them.

The first Private Practice article, Taming Templates, examines techniques to control template code bloat. There’s nothing particularly earth-shattering in there, but I noticed that a lot of people don’t seem to be aware of the fact that templates can cause a lot of duplicated code, so I thought I’d write about it.

Even if they haven’t been released under the Private Practice banner, the following articles also fit that category well:

Heise Developer: Mythos Proxy-Style

For you German speakers out there, my fifth Heise Developer article, “Mythos Proxy-Style: Wie eine verspätete Klasse neues Licht auf ein bekanntes Entwurfsmuster wirft” just went live on Heise’s site.

It examines the implementation of QProxyStyle in Qt 4.6 and, from that analysis, derives an important caveat regarding the applicability of a certain well-known design pattern.

This is the German translation of an unpublished English-language original, which I will publish here after a grace period.

From the article:

In der Qt-Gemeinde existiert ein Mythos: “QProxyStyle”. Auf der einen Seite stehen Entwickler wie David Faure, seines Zeichens KDE-Urgestein und geschätzter Kollege des Autors, die behaupten, ein QProxyStyle sei unmöglich. Auf der anderen Seite stehen Entwickler von Qt-Erweiterungen, die einen QProxyStyle entwickelt haben wollen. Eine Spurensuche im Märchenwald deckt interessante Komplikationen bei der Anwendung eines bekannten Entwurfsmusters auf.

Heise iX: QtQuick article, KDAB whitepaper; Qt Containers update

Together with my fellow KDABians Stephen Kelly and Volker Krause, I wrote a whitepaper on QtQuick usage in the KOMO project. From the whitepaper:

Developing a serious and large application from scratch, or from an existing desktop application, presents a different set of challenges compared to your normal smart-phone ‘app’. Portability to different platforms, and long-term maintainability in the face of ever-changing mobile target platforms suddenly come into play. This paper attempts to summarize the experience we gathered using the new declarative GUI framework, QtQuick, in this project.

Unfortunately, recent events (read: Tizen) have already invalidated much of the content in the supplemental box on the future of Qt, but that’s the bane of everyone writing about Qt’s future these days…

Get the English version (with slightly more details) at http://www.kdab.com/whitepapers, or read the German version (with better editing) in the current print issue of German computer magazine iX: http://www.heise.de/ix/inhalt/2011/11/114/.

In other news: I’ve updated “Understand the Qt Containers” with a discussion of the differences between STL and Qt containers regarding size types, associative container insertions, and error handling. I also mention QT_STRICT_ITERATORS now.
