Randomizing a CSV File with Standard C++

For this years student program I had to come up with a way to randomly select n students from all applicants. I wanted to do this in a clean and nice C++ program. So here it is:

Presenting Code

published at 27.10.2016 16:42

At CppCon 2015 I decided to give a small lightning talk on how to present code in the coming year. This was a reflection on visiting many C++ related conferences and seeing many talks live and online:

What does "Modern C++" really mean?

published at 13.10.2016 16:03

I submitted a talk to CppCon with Modern C++ in the title: CppCon 2016 - Jens Weller “Writing applications in modern C++ and Qt". It seemed a good title, and I think it still is. Yet it made me interested in the term "modern C++", as its used so often. And I have heard so many things what it is, and what it isn't.

Lessons learned from Meeting C++ 2015

published at 24.03.2016 16:32

Some reflections on last years Meeting C++ conference, and what changes are coming for this years Meeting C++ Conference, which will be announced next week. This year will be the 5th conference, with the experience of running the event 4 times, it will be again, the best Meeting C++ conference I have organized so far. But lets first look back, and learn from last years and previous events.

C++17 and other future highlights of C++

published at 10.03.2016 11:25

Welcome to the 3rd and last part about current proposals for C++17 and beyond. In the last part, there was an overview on the current Technical Specifications, most likely to move into C++ after C++17. The full proposal listing of 2016 sorted by subgroups contains many more proposals then I can cover.

C++17 and its Technical Specifications

published at 03.03.2016 12:23

Part 2 of my series about the current proposals for C++17. This part is covering the Technical Specifications (TS), which are currently released. Some of them will make it into C++17. Those not making it into C++17, should be available in the namespace std::experimental, if they are not a language feature.

Selecting by interface, an idea almost to good to be true

published at 27.02.2016 17:36

Last night, I've been coding until 3 am. Working on an API which will connect my CMS to JSON libraries in a generic way. For this I did study different JSON Libraries in the past weeks. I almost wrote another one ;) Yet, I had the idea to write a generic interface to interface with some of these libraries, so that my own code is not hard wired to a certain API.

Revisiting QWidgets & data, refactoring and performance

published at 18.02.2016 11:10

My CMS project has grown quite a bit, and there are a few places where I think I should refactor the code. One of the larger ones is that TreeItem::get<T> returns a pointer instead of a reference. Another one is related to how the Qt UI application is acting when opening a new panel in the TabControl. There used to be a noticeable delay...

Searching and replacing in strings with boost

published at 11.02.2016 12:41

The next big milestone for my CMS is to actually generate HTML files, and I'm almost there. I'll reach it in the next two weeks, most code is written, just a little bit of refactoring is needed. This blog post is about searching and replacing in strings. As I started last week with implementing the functionality, that turns the data in my CMS into an HTML website.
