  • CS Majors: Hardest concept(s) you learned in school?

    - by Mark Lubin
    For the CS majors out there what were the hardest CS classes or concepts that you learned in your undergraduate schooling? Did you find once you learned the basics,(data structs, OOP fundamentals, discrete math, pointers, recursion, etc) the rest followed naturally or did you hit a wall at any point in your higher classes like OS'es and Compilers? Thanks for the input!

  • What needs to be passed to an editor from a keyboard app to move the cursor one char left?

    - by yno
    What key code does an Android editor app expect the keyboard app to send when it is going to be interpreted as a left arrow? In other words, what is the keyboard program supposed to send to its calling program (some kind of editor) if the user intends to move the cursor one char to the left? A related issue: what do the minus values for the "android:codes" attribute mean? () Any pointers to these issues will be appreciated.

  • what are LPARAM and WPARAM defined as

    - by Mark Heath
    I know I'm being lazy here and I should trawl the header files for myself, but what are the actual types for LPARAM and WPARAM parameters? Are they pointers, or four byte ints? I'm doing some C# interop code and want to be sure I get it working on x64 systems.

  • Well tested C/C++ lock free queue?

    - by uj
    I am looking for a well-tested, publicly available C/C++ implementation of a lock free queue. I need at least multiple-producers/single-consumer functionality. Multiple-consumers is even better, if exists. I'm targetting VC's _Interlocked... intrinsics, though anything which is straight forward to port would be fine. Could anyone give any pointers?

  • What alternatives to __attribute__ exist on 64-bit kernels?

    - by Saifi Khan
    Hi: Is there any alternative to non-ISO gcc specific extension __attribute__ on 64-bit kernels ? Three types that i've noticed are: function attributes, type attributes and variable attributes. eg. i'd like to avoid using __attribute__((__packed__)) for structures passed over the network, even though some gcc based code do use it. Any suggestions or pointers on how to entirely avoid __attribute__ usage in C systems/kernel code ? thanks Saifi.

  • shared_ptr as class member

    - by idimba
    It's common to declared contained objects as a pointers to that class, while "forward declarating" them in header file. This in order to reduce physical dependencies in code. For example class B; // forward declaration class A { private: B* pB; }; Would it be good idea to declare such a member as shared_ptr, instead of naked pointer? I would prefer scoped_ptr, but AFAIKit it won't be in standard.

  • Changing hibernate batch size programatically

    - by user179056
    Hello, Is possible to change hibernate.jdbc.batch_size programmatically? I understand hibernate.jdbc.batch_size is a application level parameter, wanted to know if i can use it specifically for certain HQL inserts and not others. I would change the code only for those HQL inserts The big picture is that i need to introduce batch inserts to make the web application performant in some scenarios, but i do not want to jeopardize the normal inserts which work right now. Any pointers would help thanks Sameer

  • Why use an event cache with epoll_wait?

    - by user1827356
    Question: epoll man page has some pointers when using epoll with an 'event cache'. But, why would you need to maintain an event cahce at all - Isn't this the same as what epoll is supposed to be doing? Is it to avoid making multiple epoll_wait calls which might be slower than managing the events in user space? Is it to implement a custom 'priority' scheme over the cached events? Background: I'm trying to understand the strengths/shortcomings of epoll and its applicability to different situations
