  • Can IDL evaluate strings as code?

    - by Carthage
    Is there any functionality in IDL that will allow it to evaluate a a string as code? Or, failing that, is there a nice, dynamic way of including /KEYWORD in functions? For example, if I wanted to ask them for what type of map projection the user wants, is there a way to do it nicely, without large if/case statements for the /Projection_Type keyword it needs? With even a small number of user options, the combinations would cause if/case statements to get out of hand very quickly to handle all the possible options.

  • LInux C++: how do profile time wasted due to cache misses?

    - by anon
    I know that I can use gprof to benchmark my code. However, I have this problem -- I have a smart pointer that has an extra level of indirection (think of it as a proxy object). As a result, I have this extra layer that effects pretty much all functions, and screws with caching. Is there a way to measure the time my CPU wastes due to cache misses? Thanks!

  • Where can I find documentation for Scala's delayed function calls?

    - by Geo
    I saw a delayed example in David Pollak's "Beginning Scala". I tried to adapt that, by trial and error. Here's what I have: def sayhello() = { println("hello") } def delaying(t: => Unit):Unit = { println("before call") t println("after call") } delaying(sayhello()) How would you delay a function/method that takes parameters? Why can't I use parantheses when I call t? Where can I find more documentation on delaying functions?

  • lua - how to call function from above it in code (prior to it being defined)?

    - by Greg
    what is the syntax (i.e. code example) in Lua so you can call a function prior to it being defined? i.e. how do you kind of create the function, but then add it's implementation further down in code. So roughly like this: define function name (doX) here somehow (i.e. subject of this question) call doX here (further down in the code) doX implemention here (i.e. all functions down at the bottom of the file)

  • Read vs Find -- Cakephp Usage

    - by Michael
    Hi all, I was reading through a book on CakePhp Application structure, and came across both the read and find functions. I've always only used find -- when would a read be appropriate? Examples appreciated. Thanks!

  • *iPhone* Unable to symbolicate in Object Allocations instrument

    - by AkademiksQc
    Hi there, i run a C++ app from objective-c I can successfully symbolicate my function names using Shark profiler but not with the Object Allocations instrument.à In the detailed pane, i only see my C++ app name with the hexadecimal value for my C++ functions. I tried to do a "File/Re-Symbolicate Document", selecting my app folder containing both my app and my Dsym file but nothing change. Any clues? My config: xCode 3.2.2 iPhonoe SDK 3.2 Snowleopard (10.6.3) Thx.

  • Production ready alternative to Microsoft Doloto (Javascript minifier/prefetcher)?

    - by usr
    As you surely know Microsoft Doloto is tool which profiles you javascript code as it actually runs on the page and splits it in to two files: one file will be statically included in the footer of the page which contains stubs for all functions and loads the actual implementations (in file 2) in the background (under the assumption that only very litte javascript is needed on page load so you can defer downloading the rest). I found Doloto not to be production ready, it meanwhile has been canceled afaik. Is there a working alternative?

  • Database advantages? Access, MySQL, msSQL, or any others?

    - by JimZ
    Dear all Stackoverflowers, I just started to learn programming and now I'm putting this question online based on a quote: no question is silly My work needs to develop a order system based on web, which wants a database system. Since using Excel for years as a general office user, I naturally turn this to Access. However, most people say Access is very limited comparing to MySQL or MSSQL, or any other more professional database system. But after developing some functions for my company's order system, I really find Access can fulfill my request. And I also tried MSSQL to develop, which I found it not quite convenient to use. I have searched in stackoverflow and find no general answer about my doubt. Now I am sincerely hoping some experienced and professional developers could clear my doubts. Now I'm listing some Access advantages, which I don't think other database system have. I hope you could help me also find these advantages in others. 1. Access is portable, I can just copy a xxx.accdb file to my company and continue with development. 2. Access is easy to generate helpful table, for example, it will automatically generate a field that can automatically count, could be used as primary key value. 3. it is more compatable with Excel, to display and filter data. 4. importantly, it nerely needs no environment to setup, just needs MS Office to be installed. ............others However, I also find some points that MSSQL is advantaged: 1. security reasons 2. easy to backup, ( just use BACKUP..... sql statement to do it) 3. can edit stored procedure to save some functions to database ...............others specifically, I wish some friends could tell me how to make other database portable? since I usually work both at home and in office. It's a headache to move MSSQL work to my office, since the version of MSSQL is not the same. Thank you all and best regards, :)

  • How can I check for unused import in many Python files?

    - by Thierry Lam
    I remember when I was developing in C++ or Java, the compiler usually complains for unused methods, functions or imports. In my Django project, I have a bunch of Python files which have gone through a number of iterations. Some of those files have a few lines of import statement at the top of the page and some of those imports are not used anymore. Is there a way to locate those unused imports besides eyeballing each one of them in each file? All my imports are explicit, I don't usually write from blah import *

  • How classes are secure than structures ?

    - by Asad Hanif
    Structure's member are public by default ans class's members are private by default. We can access private data members through a proper channel (using member function). If we have access to member functions we can read/write data in private data member, so how it is secure...we are accessing it and we are changing data too.....

  • Is it safe to make GL calls with multiple threads?

    - by user146780
    I was wondering if it was safe to make GL calls with multiple threads. Basically I'm using a GLUtesselator and was wondering if I could divide the objects to draw into 4 and assign a thread to each one. I'm just wondering if this would cause trouble since the tesselator uses callback functions. Can 2 threads run the same callback at the same time as long as that callback does not access ant global variables? Are there also other ways I could optimize OpenGL drawing using multithreading? Thanks

Is there a way to start of all ajax calls when the previous call is complete and success function has been run? thanks

  • why my C++ output executable is so big?

    - by Vincenzo
    I have a rather simple C++ project, which uses boost::regex library. The output I'm getting is 3.5Mb in size. As I understand I'm statically linking all boost .CPP files, including all functions/methods. Maybe it's possible somehow to instruct my linker to use only necessary elements from boost, not all of them? Thanks.

  • Is it possible to restart the phone with Android SDK or NDK?

    - by J Andy
    Is it possible to programmatically restart the phone from a application (service) running on top of the Dalvik VM? If the SDK does not provide this functionality, then how about using the NDK and calling some functions provided by the kernel? I know this option is not preferred (not stable enough libs), but if it's the only option, I'll have to consider that as well.
