With Qt5 there is a new API for reading and writing JSON files in Qt. In the last days I had the chance to play around with this API, as I implemented importing and exporting different data sets from and to JSON. Qt has...
Today I had a little fun with Qt and wrote a widget for displaying a bar graph. I have two different situations where I need the bar graph in my back end: displaying the votes a single talk got, and displaying one big bar graph of all the talks.
I've just written this afternoon a small tool for the talk-vote for Meeting C++ 2014. As the call for papers ends on Sunday, the voting comes closer. Last year only a few people on the program committee could vote, this year its going to be around 300. This is 10 times more then last year. In this way I want to give the audience a chance to influence the program.
So, for one year I've been reading Proposals for the C++ Committee, some thoughts on where its going, and where its currently at. And now that C++14 is in its final draft state, also a look into the Standards beyond C++14.
During the last few weeks I got interested in the Google Summer of Code (GSoC), as I did read some emails on the boost mailing lists about it. The Google Summer of Code is for a lot of open source projects an important opportunity to improve and extend their code base, and in 2014 it happens for the 10th time!
I just finished a little tool, which needs to crawl websites, in this case mostly blog posts to extract a few fields. I have been working with QtWebkit for this purpose for a while, one larger project I am working on needs it to index certain websites...
I've written earlier this year about smart pointers in C++, today I just would like to write a little more about shared_ptr. Especially about addiction to shared_ptr, and why you should use unique_ptr in C++11.
The 4th and last part about the C++ Papers for Issaquah, where the C++ committee meets this week. I already covered the first batch of proposals from the Library subgroup in the previous part, now its all about papers from Library, Graphics, Networking, Numerics and Undefined Behavior.
In february the C++ committee is going to meet for a week in Issaquah, it could be the final Meeting for C++14, the papers in this series will reflect both, C++14 and the standard that will come after it...
My last blog post in 2013 was about the pointer in C++, and how most of it's daily usages in C++ is now being replaced by classes replacing or managing the pointer. The last, the RAII like objects called smart pointers is the topic of this post. I want to give an overview over the choices one can make when using smart pointers.
The last weeks after Meeting C++ 2013 I've been thinking a lot about C++, and also a little bit about pointers. While C++11 brought only little changes for pointers (nullptr f.e.), the semantics and usage of pointers in C++ has changed over the last years.
