  • siftware to manage applications within business.

    - by Richard Friend
    Hi I have been tasked to either find an off the shelf solution or to build inhouse some software that can maintain a list of all of the applications within our business, assign them to the different business areas that use them and list all the servers, documents, knowledge base etc that relate to the app in question. Does anyone know of any existing software that can do this ? Regards

  • Count max rectangles number, that can be placed inside character

    - by Nickolay
    Hi, I need a solution for quite complex problem. Exactly, I need to calculate the number of rectangles that can be placed inside letter/character with given size, considering that all rectangles are the same size, but it(the size) and the letter/character(of some regular specific font) itself can be changed by user(this will be used as webside calculator of signboard price). If describe this graphically, it looks like this. Any ideas or useful links will be much appreciated. Thanks in advance

  • Rails Association Question (addendum)...

    - by keruilin
    My original question and accepted solution was posted here: http://stackoverflow.com/questions/2483640/rails-association-question. Check that out first. My follow-up question is this: I want to return an object that has both the user attributes and the race attributes. That way I can access, for example, the user's name and the fastest_time. How can this be accomplished? I've tried several approaches, but none I've been satisfied with.

  • Move 3 rectangles up in their X but keep order of rectangles

    - by Nicolas Martel
    I have 3 rectangles being rendered here. Let's say i wanted to move them all above the line yet keep their order, how would i go about that? I tried subtracting the Y and height rather than adding the Y it but as expected, the lower rectangle goes at the top, middle stays in the middle and top goes to the bottom before: after: So is there any simple solution to render them just above rather than having to change all values ?

  • Why do calls to waveOutGetPosition hang?

    - by MusiGenesis
    I'm using the winmm.dll API method waveOutGetPosition to get the current position of the playback of a WAV file. Sometimes this works as expected for me, but eventually one of the calls never returns and my application locks up. I found this thread with a few users who have experienced the same problem: http://social.msdn.microsoft.com/Forums/en-US/windowsgeneraldevelopmentissues/thread/c6a1e80e-4a18-47e7-af11-56a89f638ad7 but no solution. Has anyone run into this problem before?

  • filtering directly and indirectly connected things from list

    - by Andreas Romeyke
    Hello, if you have a function "test a b" which returns true if a and b are connected directly and if you have a given unordered list of things, what would be an elegant and fast solution to filter all connected things from given list? Example: let test a b = let diff = a - b in diff == 0 ;; let lst = [4;1;7;3;8;9;2;0] ;; filter_connected 2 lst ;; - [4;1;3;2;0] Any hints?

  • mkdir -p functionality in python

    - by SetJmp
    Is there a way to get functionality similar to mkdir -p on the shell... from within python. I am looking for a solution other than a system call. I am sure the code is less than 20 lines... really I am wondering if someone has already written it?

  • Odd behavior when recursively building a return type for variadic functions

    - by Dennis Zickefoose
    This is probably going to be a really simple explanation, but I'm going to give as much backstory as possible in case I'm wrong. Advanced apologies for being so verbose. I'm using gcc4.5, and I realize the c++0x support is still somewhat experimental, but I'm going to act on the assumption that there's a non-bug related reason for the behavior I'm seeing. I'm experimenting with variadic function templates. The end goal was to build a cons-list out of std::pair. It wasn't meant to be a custom type, just a string of pair objects. The function that constructs the list would have to be in some way recursive, with the ultimate return value being dependent on the result of the recursive calls. As an added twist, successive parameters are added together before being inserted into the list. So if I pass [1, 2, 3, 4, 5, 6] the end result should be {1+2, {3+4, 5+6}}. My initial attempt was fairly naive. A function, Build, with two overloads. One took two identical parameters and simply returned their sum. The other took two parameters and a parameter pack. The return value was a pair consisting of the sum of the two set parameters, and the recursive call. In retrospect, this was obviously a flawed strategy, because the function isn't declared when I try to figure out its return type, so it has no choice but to resolve to the non-recursive version. That I understand. Where I got confused was the second iteration. I decided to make those functions static members of a template class. The function calls themselves are not parameterized, but instead the entire class is. My assumption was that when the recursive function attempts to generate its return type, it would instantiate a whole new version of the structure with its own static function, and everything would work itself out. The result was: "error: no matching function for call to BuildStruct<double, double, char, char>::Go(const char&, const char&)" The offending code: static auto Go(const Type& t0, const Type& t1, const Types&... rest) -> std::pair<Type, decltype(BuildStruct<Types...>::Go(rest...))> My confusion comes from the fact that the parameters to BuildStruct should always be the same types as the arguments sent to BuildStruct::Go, but in the error code Go is missing the initial two double parameters. What am I missing here? If my initial assumption about how the static functions would be chosen was incorrect, why is it trying to call the wrong function rather than just not finding a function at all? It seems to just be mixing types willy-nilly, and I just can't come up with an explanation as to why. If I add additional parameters to the initial call, it always burrows down to that last step before failing, so presumably the recursion itself is at least partially working. This is in direct contrast to the initial attempt, which always failed to find a function call right away. Ultimately, I've gotten past the problem, with a fairly elegant solution that hardly resembles either of the first two attempts. So I know how to do what I want to do. I'm looking for an explanation for the failure I saw. Full code to follow since I'm sure my verbal description was insufficient. First some boilerplate, if you feel compelled to execute the code and see it for yourself. Then the initial attempt, which failed reasonably, then the second attempt, which did not. #include <iostream> using std::cout; using std::endl; #include <utility> template<typename T1, typename T2> std::ostream& operator <<(std::ostream& str, const std::pair<T1, T2>& p) { return str << "[" << p.first << ", " << p.second << "]"; } //Insert code here int main() { Execute(5, 6, 4.3, 2.2, 'c', 'd'); Execute(5, 6, 4.3, 2.2); Execute(5, 6); return 0; } Non-struct solution: template<typename Type> Type BuildFunction(const Type& t0, const Type& t1) { return t0 + t1; } template<typename Type, typename... Rest> auto BuildFunction(const Type& t0, const Type& t1, const Rest&... rest) -> std::pair<Type, decltype(BuildFunction(rest...))> { return std::pair<Type, decltype(BuildFunction(rest...))> (t0 + t1, BuildFunction(rest...)); } template<typename... Types> void Execute(const Types&... t) { cout << BuildFunction(t...) << endl; } Resulting errors: test.cpp: In function 'void Execute(const Types& ...)

  • Recursion with an Array; can't get the right value to return

    - by Matt
    Recursive Solution: Not working! Explanation: An integer, time, is passed into the function. It's then used to provide an end to the FOR statement (counter<time). The IF section (time == 0) provides a base case where the recursion should terminate, returning 0. The ELSE section is where the recursive call occurs: total is a private variable defined in the header file, elsewhere. It's initialized to 0 in a constructor, elsewhere. The function calls itself, recursively, adding productsAndSales[time-1][0] to total, again, and again, until the base call. Then the total is returned, and printed out later. Well, that's what I hoped for anyway. What I imagined would happen is that I would add up all the values in this one column of the array and the value would get returned, and printed out. Instead if returns 0. If I set the IF section to "return 1", I noticed that it returns powers of 2, for whatever value time is. EG: Time = 3, it returns 2*2 + 1. If time = 5, it returns 2*2*2*2 + 1. I don't understand why it's not returning the value I'm expecting. int CompanySales::calcTotals( int time ) { cout << setw( 4 ); if ( time == 0 ) { return 0; } else { return total += calcTotals( productsAndSales[ time-1 ][ 0 ]); } } Iterative Solution: Working! Explanation: An integer, time, is passed into the function. It's then used to provide an end to the FOR statement (counter<time). The FOR statement cycles through an array, adding all of the values in one column together. The value is then returned (and elsewhere in the program, printed out). Works perfectly. int CompanySales::calcTotals( int time ) { int total = 0; cout << setw( 4 ); for ( int counter = 0; counter < time; counter++ ) { total += productsAndSales[counter][0]; } return total0; }

  • I need a simple command line program to transform XML using XSLT

    - by fuzzy lollipop
    I am on OSX Snow Leopard (10.6.2) I can install anything I need to. I would preferably like a Python or Java solution. I have searched on Google and found lots of information on writing my own program to do this, but this is a just a quick and dirty experiment so I don't want to invest a lot of time on writing a bunch of code to do this, I am sure someone else has done this already.

  • Changing CSS for Last li

    - by PF1
    Hi Everyone: I am wondering if there is some way to change a css attribute for the last li in a list using CSS. I have looked into using :last-child, but this seems really buggy and I can't get it to work for me. I will use Javascript to do this if necessary, but I want to know if anyone can think up a solution in CSS. Thanks for any help!

  • HTML/JavaScript compation for security.

    - by BCS
    I just ran across this point that references a security vulnerability in Web Apps that depends on looking at the size of encrypted web pages to deduce what the uses is doing. The simplest solution to this I can think of would be to use a tool to minify all static content so that (after encryption) only a small number of result sizes exist so as to minimize the information available to an eavesdropper. Are there any tools for doing this?

  • What's a good 2nd level cache for JEE applications?

    - by Hank
    Can anyone recommend a good 2nd level object caching solution for JEE 6 applications, and give background to your recommendation? I'm using JPA 2.0 as persistence provider. I am particularly worried about having to run the cache client as a single-thread / singleton bean. Is that the case? If so, is that an issue? I've good experience using memcached from a PHP webapp, but PHP is of course single-threaded, so that was never an issue...

  • method with two parameters which both need to be double dispatched

    - by mixm
    lets say i have a method which has two parameters. i have been implementing them as: if(aObj instance of Marble) { if(bObj instance of Bomb) { this.resolve((Marble)aObj,(Bomb)bObj); } } as you can see its not a very pretty solution. i plan to implement using double dispatching, but with two parameters which both need double dispatching, im afraid im a bit stumped. any ideas please. im implementing in java btw.

  • Autocomplete server-side implementation

    - by toluju
    What is a fast and efficient way to implement the server-side component for an autocomplete feature in an html input box? I am writing a service to autocomplete user queries in our web interface's main search box, and the completions are displayed in an ajax-powered dropdown. The data we are running queries against is simply a large table of concepts our system knows about, which matches roughly with the set of wikipedia page titles. For this service obviously speed is of utmost importance, as responsiveness of the web page is important to the user experience. The current implementation simply loads all concepts into memory in a sorted set, and performs a simple log(n) lookup on a user keystroke. The tailset is then used to provide additional matches beyond the closest match. The problem with this solution is that it does not scale. It currently is running up against the VM heap space limit (I've set -Xmx2g, which is about the most we can push on our 32 bit machines), and this prevents us from expanding our concept table or adding more functionality. Switching to 64-bit VMs on machines with more memory isn't an immediate option. I've been hesitant to start working on a disk-based solution as I am concerned that disk seek time will kill performance. Are there possible solutions that will let me scale better, either entirely in memory or with some fast disk-backed implementations? Edits: @Gandalf: For our use case it is important the the autocompletion is comprehensive and isn't just extra help for the user. As for what we are completing, it is a list of concept-type pairs. For example, possible entries are [("Microsoft", "Software Company"), ("Jeff Atwood", "Programmer"), ("StackOverflow.com", "Website")]. We are using Lucene for the full search once a user selects an item from the autocomplete list, but I am not yet sure Lucene would work well for the autocomplete itself. @Glen: No databases are being used here. When I'm talking about a table I just mean the structured representation of my data. @Jason Day: My original implementation to this problem was to use a Trie, but the memory bloat with that was actually worse than the sorted set due to needing a large number of object references. I'll read on the ternary search trees to see if it could be of use.

  • How to create dependencies in automake?

    - by Sam
    Hello, I have a Makefile.am file right now that looks like this: lib_LIBRARIES = foo.a foo_a_SOURCES = bar.F90 baz.F90 When compiled, bar.F90 gives bar.o. However, bar.F90 depends on several other Fortran files (cat.F90, dog.F90, pig.F90). I want to set up Automake to rebuild bar.o if the source of one of these dependencies change. I've been reading the GNU manuals for automake/autoconf and was unable to find a solution to this. Thanks for reading.

  • How to set which version of the VC++ runtime Visual Studio 2005 targets

    - by TallGuy
    I have an application that contains a VC++ project (along with C# projects). Previously, (i.e. during the last year or so) when a build has been done, Visual Studio 2005 appears to be targeting the VC++ runtime version 8.0.50727.762. At least, that is what the Assembly.dll.intermediate.manifest file is telling me: <?xml version='1.0' encoding='UTF-8' standalone='yes'?> <assembly xmlns='urn:schemas-microsoft-com:asm.v1' manifestVersion='1.0'> <dependency> <dependentAssembly> <assemblyIdentity type='win32' name='Microsoft.VC80.CRT' version='8.0.50727.762' processorArchitecture='x86' publicKeyToken='1fc8b3b9a1e18e3b' /> </dependentAssembly> </dependency> </assembly> This version number matches the Visual Studio 2005 version number. The application worked fine when deployed to the webserver. The sun was shining, the birds were singing and all was right with the world. Now something has changed. I don't know what - a security patch, an obscure Visual Studio setting or something. Now Visual Studio 2005 seems to be targeting the wrong version of the VC++ runtime: <?xml version='1.0' encoding='UTF-8' standalone='yes'?> <assembly xmlns='urn:schemas-microsoft-com:asm.v1' manifestVersion='1.0'> <dependency> <dependentAssembly> <assemblyIdentity type='win32' name='Microsoft.VC80.CRT' version='8.0.50727.4053' processorArchitecture='x86' publicKeyToken='1fc8b3b9a1e18e3b' /> </dependentAssembly> </dependency> </assembly> When I deploy the application to the webserver, I get the dreaded This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. (Exception from HRESULT: 0x800736B1) error. This problem occurs even when I recompile previous versions of the application. I can absolutely guarantee that nothing at all has changed in the solution - we zip up the entire contents of the solution as part of the build process and archive it. I have unzipped a number of these to a temp directory, verified that the previous manifest file refers to 8.0.50727.762, recompiled using exactly the same command at the command line and then verified that the new manifest file now refers to 8.0.50727.4053. I am using Microsoft Visual Studio 2005 Version 8.0.50727.762 (SP.050727-7600) and Microsoft Visual C++ 2005 77646-008-0000007-41610. Why would Visual Studio revert to a previous version of the VC++ runtime? How do I specify which version it should use? What is going wrong here?
