c++ today: February 2010

http://www.cpp-today.blogspot.com/2010_02_01_archive.html

Almost" day by day thoughts on code inspected. Friday, February 12, 2010. I still see people with the doubt: "shall I use an assert or throw an exception? Let me whine a bit about the usage of asserts first. Overall people code badly and I mean it, hence assertions are not used enough. Having say that, "assert" and "exception" have different. A nice rule that drives the lazy bone programmers to use more assert is: who ever write a code that provides a set of data that asserted then the same person is res...

Almost" day by day thoughts on code inspected. Saturday, May 31, 2008. False Sharing hits again! You can ask what "false sharing" is? Consider for example the following case:. Char a[10]; char b[10]; start thread that works on a; start thread that works on b;. I've had to work on an algorithm that had that very issue and the following code, even if useless, exploits the same problem:. Std: cout std: hex;. Boost: thread group tg;. You should be able to compile and link it with:. The goal is to have both t...

Almost" day by day thoughts on code inspected. Sunday, February 16, 2014. The under-evaluated delete specifier. As you should know by now in C 11 we are able disable certain signatures in our classes. Most of the time this is used to disable copy constructor and assignment operators. This way is much better than the old way where the programmer had to declare private both member and then not implement them getting an error either at compile time or either at linking time.

Friday, November 28, 2008. Gaetano, the owner of cpp-today blog (see the link on the right) read my previous post and explain me that a constructor like T(T&) is the base of the "Move Constructor Idiom". The programmer that wrote the (horrible) code of the previous post hasn't thinking about that, he just don't know the correct prototype of a copy constructor, but I didn't know anything about that move constructor so I read something about.

Tuesday, June 24, 2008. What a nice weekend! After a 10 days waiting, finally I found the surprise my sweet "zavorrina" prepared for me :-). We went by motorcycle, with Andrea and Francesca, to Porretta to listen to Francesco Guccini! The concert was wonderful, and the place too! He played his famous song, like "la Locomotiva" and "Il Vecchio e il Bambino" as well as less famous ones, cracking jokes among them. and, of course, drinking a lot of wine glasses!

developer for work: October 2008

http://developer4work.blogspot.com/2008_10_01_archive.html

Thursday, October 16, 2008. Today I fix a stupid, trivial issue on building a win32 executable from python code. the problem was a missing library, but the library was in the correct place! Al last, I fund there are two python interpreter on my machine, the one I installed and another. installed by cygwin! Clearly, when I write "python.exe" on my prompt the first interpreter the system find is the cygwin one, that hasn't the libraries I need. just add the correct path and the issue disappeared!

developer for work: Why following the standard is the right thing..

http://developer4work.blogspot.com/2008/11/why-following-standard-is-right-thing.html

Thursday, November 27, 2008. Why following the standard is the right thing. Today I saw an interesting example of bad C coding:. Let's say we have a class, named A, that have a strange copy constructor prototype:. The standard says that the copy constructor for a type T has to have this prototype:. So, the instance passed as argument has to be const! My compiler (g 4.2.4), doesn't complain even if I specify -Wall and -pedantic, and the code is generated. A MyClass: getA() const {return this- the a;}.

C++ Tip Of The Day

C Tip Of The Day. Tuesday, September 1, 2015. Building your own unit-testing framework. When you want to apply a test-driven design approach, you will probably find that almost none of the unit-test frameworks really fits your needs. So, if your company does not already use a testing framework, it is worth developing your own framework! Monday, December 8, 2014. C Bloopers - references to temporary objects. Breaking encapsulation of classes to expose internal state, is always a source for potential errors.
