Some praise for my Qt book

You might perhaps already know that I recently wrote a book (blogged about it here)! In the book I discussed various general program performance topics but also some more specific, Qt related ones, for example Qt's graphical or networking performance.
 
Recently I was very happy (and very surprozed) to have read some kind words about my book, and I just wanted to show off a little 😇 and cite them here. So let's start!

First Ivica* mentioned he had my book, and it wouldn't be that bad:


After I thanked him, he said he actually liked it!


What I was particularly pleased about is (beside the "well written" phrase) that:
  • 95% ... can be applied to other frameworks
  • very good read for intermediate/advanced C++ developer
Why? Because all of that were my goals when writting the book, so I can congratulate myself on a good job! What can I say, thanks a lot, Ivica!

Thank you!

You may ask what the book was about, really? Let's have a look:
  • Part I - Basics
    • Intro - basic performance wisdom and techniques, hardware architecture and its impact.
    • Profiling - performance tools and how to use them. As I said, we don't want to make it easy for us and look at the Windows platform!
    • C++ - how performant is C++ really? And what are optimizations the compiler (and linker) can do?
  • Part II - General Techniques
    • Data structures and algorithms - what is the performance of Qt containers and strings? Do we have to use them?
    • Multithreading - Qt's take on threading and how to speed up your program with concurrency.
    • Fails - some more memorable performance problems I encountered in my programming career.
  • Part III - Selected Qt Modules
    • File I/O etc - Qt and file system performance, JSON and XML parsing. Also memory mapped files and caching.
    • Graphic - GUI, OpenGL, widget and QML performance. Probably the most interesting part of the book.
    • Networking - network performance and network support in Qt. Because we live in the ubiquitous connectivity era!
  • Part IV - Goodies
    • Mobile and embedded - how to use Qt on mobile and embedded (a kind of advanced chapter applying all we have learned before to two specific platforms)
    • Testing - a goodie chapter about testing techniques, GUI testing and performance regression tests. At the end this chapter turned out pretty interesting!
Got you interested? Then read my detailed blogpost introducing the book!

* I maybe have to mention, that Ivica has a well established reputation in the performance community -  just look up these links:
Impressive, isn't it?
