  • How can I improve these online java programming puzzles I wrote for my (middle/high school) students?

    - by Arcymag
    I'm teaching some middle and high school students programming right now, and I found that some of them really liked online programming puzzles. So I created http://www.kapparate.com/coder/ , and right now there's 4 categories of puzzles. All the puzzles are set up right now so that variables are pre-initialized, and the user plugs in some code in the middle. For example, the problem might say these are pre-initialized: int x = ????; int y = ????; int z; and then the program might ask the student to write the final line of code: z = x + y;. Now I know I could go a long way in improving the usability of this site (like having an area that lists the pre-defined variables), but I was wondering if this concept seems sound. I know some sites have kids fill in functions, but not all of my students know what functions are yet, and I'm trying to introduce online programming puzzles before that.

  • In what way I can implement packet filtering function in C++/C#?

    - by Network study
    Background: I am going to design a firewall-like application (with GUI) which will include several functions such as Packet sniffing and packet filtering. Both of the functions should be implemented to support different protocol levels including application, transport, network and link layer. I only know a little in C#.Net programming to perform the IP packet sniffing. It is also known that packet filtering requires the techniques in WFP or LSP and packet sniffing in application requires dll hooking. Questions: I am not sure which programming language(either C++ or C#) would be suitable for designing such an application described above. If I want to implement the packet filtering function, any libraries will be needed? edit01: Someone suggest that winDivert would be helpful, is it true?

  • What programming language matches this description? [on hold]

    - by Benubird
    I am looking for a functional language that is basically dynamic programming - i.e. one where functions are first-class objects - but where all function calls are asynchronous by default; i.e. you define function X(a,b) = (Y(a)+Z(b)), and when X() is called, it sees it is waiting for the return from two functions, runs one in the current thread, and spawns a new thread to run the other. The future is very much parallel processing; multiple cores, multiple machines, the internet of things, etc. and I was wondering if there was a language specifically designed to make this kind of parallelization easy. I currently have only used imperative languages (c, php, java, ruby, etc), so I don't know anything about what kind of functional languages are available.

  • Separate parts of a game engine [on hold]

    - by user272716
    I'm pretty new in developing videogames. By now I only used SDL with C/C++ to create games. I'm currently learning OpenGL and I realized that to be fluid and easy to maintain the code must be logically separated. Since I want to use OpenGLES on iOS and Android I was wondering how the engine must be imagined in a technical way, some questions came up: Do I have to separate input/update functions from draw functions in different threads? Is there only one proper way to think a game engine/loop? What kind of assets should I use to create a 3D game using openGl ES to get better performance?

  • Application window as polygon texture?

    - by nekome
    Is there a way, or method, to have some application rendered as texture in 3D scene on some polygon, and also have full interactivity with it? I'm talking about Windows platform, and maybe OpenGL but I guess it doesn't matter is it OGL or DX. For example: I run Calculator using WINAPI functions (preferably hidden, not showing on desktop) and I want to render it inside 3D scene on some polygon but still be able to type or click buttons and have it respond. My idea to realize this is to have WINAPI take screenshot (or render it to memory if possible) of that Calculator and pass it to OpenGL as texture for each frame (I'm experimenting with SDL through pygame) and for mouse interactivity to use coordination translation and calculate where on application window it would act, and then use WINAPI functions such as SetCursorPos to set cursor ant others to simulate click or something else. I haven't found any tutorials with topic similar to this one. Am I on a right track? Is there better way to do this if possible at all?

  • How do I correctly multiply an XMMATRIX by a scalar?

    - by user43129
    Using DirectXMath and its XMMATRIX structure in C++ and Direct X 11, how does one multiply that matrix structure by a single float scalar? I want to implement the operation B = A * f; where A and B are XMMATRIX and f is a float. I found all sorts of functions to multiply a matrix by another matrix or a vector. I found all sorts of functions to construct matrices. I could find no scalar multiplication! Why is there no such function? Is there no use case? Did I miss something? How do I implement scalar multiplication?

  • What Does Google Social Search Mean For Website Optimisation?

    Google's latest output, Social Search, allows users to search for information via their personal connections on Twitter and other networking sites. With social search rapidly growing in popularity, the idea is basically to get the input of a user's friends, rather than anonymous websites. Social search results are incorporated right into those of a normal search engine results page (SERP) similar to how images, videos and other content are currently integrated into regular listings.

  • certain Smarty tags don't work in OpenX templates

    - by mikez302
    I am on a team that is developing an OpenX plugin, and I am responsible for the UI. I noticed that if I use certain Smarty tags in my template, the app doesn't work and I see an error message, similar to this: Plugin by name 'Html_select_date' was not found in the registry; used paths: default_views_helpers_: /openx/www/admin/plugins/myApp/application/modules/default/views/helpers/ OX_OXP_UI_View_Helper_: /openx/www/admin/plugins/myApp/application/../library/OX/OXP/UI/View/Helper/ OX_UI_View_Helper_: /openx/www/admin/plugins/myApp/application/../library/OX/UI/View/Helper/ Zend_View_Helper_: Zend/View/Helper/ (stack trace) The stack trace looks like this: #0 /openx/www/admin/plugins/myApp/library/Zend/View/Abstract.php(1117): Zend_Loader_PluginLoader-load('Html_select_dat...') #1 /openx/www/admin/plugins/myApp/library/Zend/View/Abstract.php(568): Zend_View_Abstract-_getPlugin('helper', 'html_select_dat...') #2 /openx/www/admin/plugins/myApp/library/OX/UI/Smarty/SmartyWithViewHelper.php(25): Zend_View_Abstract-getHelper('html_select_dat...') #3 /openx/var/templates_compiled/%2Fdefault%2Fviews%2Fscripts%2Findex%2Fview-reports.html^%%E8^E80^E80B56F2%%view-reports.html.php(38): OX_UI_Smarty_SmartyWithViewHelper-callViewHelper('html_select_dat...', Array) #4 /openx/lib/smarty/Smarty.class.php(1274): include('/openx...') #5 /openx/www/admin/plugins/myApp/library/OX/UI/View/SmartyView.php(103): Smarty-fetch('/openx...') #6 /openx/www/admin/plugins/myApp/library/Zend/View/Abstract.php(832): OX_UI_View_SmartyView-_run('/openx...') #7 /openx/www/admin/plugins/myApp/library/OX/UI/View/SmartyView.php(151): Zend_View_Abstract-render('index/view-repo...') #8 /openx/www/admin/plugins/myApp/library/OX/UI/View/Helper/WithViewScript.php(23): OX_UI_View_SmartyView-render('index/view-repo...') #9 /openx/www/admin/plugins/myApp/application/modules/default/views/helpers/ViewReports.php(5): OX_UI_View_Helper_WithViewScript::renderViewScript('index/view-repo...', Array) #10 /openx/www/admin/plugins/myApp/application/modules/default/controllers/IndexController.php(98): Default_Views_Helpers_ViewReports-renderPage() #11 /openx/www/admin/plugins/myApp/library/Zend/Controller/Action.php(512): IndexController-viewReportsAction() #12 /openx/www/admin/plugins/myApp/library/Zend/Controller/Dispatcher/Standard.php(288): Zend_Controller_Action-dispatch('viewReportsActi...') #13 /openx/www/admin/plugins/myApp/library/Zend/Controller/Front.php(945): Zend_Controller_Dispatcher_Standard-dispatch(Object(Zend_Controller_Request_Http), Object(Zend_Controller_Response_Http)) #14 /openx/www/admin/plugins/myApp/application/bootstrap.php(117): Zend_Controller_Front-dispatch() #15 /openx/www/admin/plugins/myApp/public/index.php(7): require('/openx...') #16 {main} This does not happen with all Smarty tags. For example, I can use {if}, {foreach}, or {assign} tags without any problems. But whenever I try to use {html_select_date}, {html_image}, or {html_table}, I get the errors. In case this matters, the programmer who is designing the plugin copied the openXWorkflow plugin and made some changes. I noticed that the openXWorkflow plugin has a file (openx/plugins_repo/openXWorkflow/www/admin/plugins/openXWorkflow/library/OX/UI/Smarty/SmartyCompilerWithViewHelper.php) with a class that overrides the default Smarty compiler, supposedly with the ability to compile shorthands for calling ZF view helpers. That file has a list of Smarty functions, but the list is incomplete. If I add the functions to the list, or simply delete the file, my template works fine, but I don't like to change library files. It may make the app hard to maintain, and I don't know if it will mess up something else. The file has the comment "There is no easy access to the list of Smarty's built-in functions so we need to list them here. HTML-specific functions are not included as we cover HTML generation separately.", so it seems like certain Smarty functions may be disabled on purpose for some reason. Will anything bad happen if I try to use them? If, for example, I want to use the {html_select_date} tag in my template, how would I go about doing that? Keep in mind that much of this stuff is new and unfamiliar to me. This is my first time ever using OpenX or Smarty, and I only have a little bit of experience with the Zend framework. Please let me know if we are using the wrong approach.

  • JavaScript String Library - Hitting a Minor Roadblock

    - by OneNerd
    Ok - am trying to create a string library that contains a handful of useful things missing from JavaScript. Here is what I have so far: ;function $__STRING__$(in_string) { /* internal functions */ this.s = in_string; this.toString = function(){return this.s;}; /******* these functions CAN be chained (they return the $__STRING__$ object) ******/ this.uppercase = function(){this.s = this.s.toUpperCase(); return this;}; this.lowercase = function(){this.s = this.s.toLowerCase(); return this;}; this.trim = function(){this.s = this.s.replace(/^\s+|\s+$/g,""); return this;}; this.ltrim = function(){this.s = this.s.replace(/^\s+/,""); return this;}; this.rtrim = function(){this.s = this.s.replace(/\s+$/,""); return this;}; this.striptags = function(){this.s = this.s.replace(/<\/?[^>]+(>|$)/g, ""); return this;}; this.escapetags = function(){this.s = this.s.replace(/</g,"<").replace(/>/g,">"); return this;}; this.unescapetags = function(){this.s = this.s.replace(/</g,"<").replace(/>/g,">"); return this;}; this.underscorize = function(){this.s = this.s.replace(/ /g,"_"); return this;}; this.dasherize = function(){this.s = this.s.replace(/ /g,"-"); return this;}; this.spacify = function(){this.s = this.s.replace(/_/g," "); return this;}; this.left = function(length){this.s = this.s.substring(length,0); return this;}; this.right = function(length){this.s = this.s.substring(this.s.length,this.s.length-length); return this;}; this.shorten = function(length){if(this.s.length<=length){return this.s;}else{this.left(this.s,length)+"..."; return this;}}; this.mid = function(start,length){return this.s.substring(start,(length+start));}; this._down = function(){return this.s;}; // breaks chain, but lets you run core js string functions /******* these functions CANNOT be chained (they do not return the $__STRING__$ object) ******/ this.contains = function(needle){if(this.s.indexOf(needle)!==-1){return true;}else{return false;}}; this.startswith = function(needle){if(this.left(this.s,needle.length)==needle){return true;}else{return false;}}; this.endswith = function(needle){if(this.right(this.s,needle.length)==needle){return true;}else{return false;};}; } function $E(in_string){return new $__STRING__$(in_string);} String.prototype._enhance = function(){return new $__STRING__$(this);}; String.prototype._up = function(){return new $__STRING__$(this);}; It works fairly well, and I can chain commands etc. I set it up so I can cast a string as an enhanced string these 2 ways: $E('some string'); 'some string'._enhance(); However, each time I want to use a built-in string method, I need to convert it back to a string first. So for now, I put in _down() and _up() methods like so: alert( $E("hello man").uppercase()._down().replace("N", "Y")._up().dasherize() ); alert( "hello man"._enhance().uppercase()._down().replace("N", "Y")._up().dasherize() ); It works fine, but what I really want to do it be able to use all of the built-in functions a string can use. I realize I can just replicate each function inside my object, but I was hoping there was a simpler way. So question is, is there an easy way to do that? Thanks -

  • Haskell: monadic takeWhile?

    - by Mark Rushakoff
    I have some functions written in C that I call from Haskell. These functions return IO (CInt). Sometimes I want to run all of the functions regardless of what any of them return, and this is easy. For sake of example code, this is the general idea of what's happening currently: Prelude> let f x = print x >> return x Prelude> mapM_ f [0..5] 0 1 2 3 4 5 Prelude> I get my desired side effects, and I don't care about the results. But now I need to stop execution immediately after the first item that doesn't return my desired result. Let's say a return value of 4 or higher requires execution to stop - then what I want to do is this: Prelude> takeWhile (<4) $ mapM f [0..5] Which gives me this error: <interactive:1:22: Couldn't match expected type `[b]' against inferred type `IO a' In the first argument of `mapM', namely `f' In the second argument of `($)', namely `mapM f ([0 .. 5])' In the expression: takeWhile (< 4) $ mapM f ([0 .. 5]) And that makes sense to me - the result is still contained in the IO monad, and I can't just compare two values contained in the IO monad. I know this is precisely the purpose of monads -- chaining results together and discarding operations when a certain condition is met -- but is there an easy way to "wrap up" the IO monad in this case to stop executing the chain upon a condition of my choosing, without writing an instance of MonadPlus? Can I just "unlift" the values from f, for the purposes of the takeWhile? Is this a solution where functors fit? Functors haven't "clicked" with me yet, but I sort of have the impression that this might be a good situation to use them. Update: @sth has the closest answer to what I want - in fact, that's almost exactly what I was going for, but I'd still like to see whether there is a standard solution that isn't explicitly recursive -- this is Haskell, after all! Looking back on how I worded my question, now I can see that I wasn't clear enough about my desired behavior. The f function I used above for an example was merely an example. The real functions are written in C and used exclusively for their side effects. I can't use @Tom's suggestion of mapM_ f (takeWhile (&lt;4) [0..5]) because I have no idea whether any input will really result in success or failure until executed. I don't actually care about the returned list, either -- I just want to call the C functions until either the list is exhausted or the first C function returns a failure code. In C-style pseudocode, my behavior would be: do { result = function_with_side_effects(input_list[index++]); } while (result == success && index < max_index); So again, @sth's answer performs the exact behavior that I want, except that the results may (should?) be discarded. A dropWhileM_ function would be equivalent for my purposes. Why isn't there a function like that or takeWhileM_ in Control.Monad? I see that there was a similar discussion on a mailing list, but it appears that nothing has come of that.

  • map with string is broken?[solved]

    - by teritriano
    Yes. I can't see what im doing wrong the map is string, int Here the method bange::function::Add(lua_State *vm){ //userdata, function if (!lua_isfunction(vm, 2)){ cout << "bange: AddFunction: First argument isn't a function." << endl; return false;} void *pfunction = const_cast<void *>(lua_topointer(vm, 2)); char key[32] = {0}; snprintf(key, 32, "%p", pfunction); cout << "Key: " << key << endl; string strkey = key; if (this->functions.find(strkey) != this->functions.end()){ luaL_unref(vm, LUA_REGISTRYINDEX, this->functions[strkey]);} this->functions[strkey] = luaL_ref(vm, LUA_REGISTRYINDEX); return true; Ok, when the code is executed... Program received signal SIGSEGV, Segmentation fault. 0x00007ffff6e6caa9 in std::basic_string<char, std::char_traits<char>, std::allocator<char> > ::compare(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&) const () from /usr/lib/libstdc++.so.6 Seriously, what's wrong with my code. Thanks for help. Edit 1: Ok, I've done the solution and still fails. I've tried directly insert a string but gives the same error. Let's see, the object is a bange::scene inherited from bange::function. I create the object with lua_newuserdata: bange::scene *scene = static_cast<bange::scene *>(lua_newuserdata(vm, sizeof(bange::scene))); (...) scene = new (scene) bange::scene(width, height, nlayers, vm); I need this for LUA garbage collection. Now the access to bange::function::Add from Lua: static int bangefunction_Add(lua_State *vm){ //userdata, function bange::function *function = reinterpret_cast<bange::function *>(lua_touserdata(vm, 1)); cout &lt&lt "object with bange::function: " &lt&lt function << endl; bool added = function->bange::function::Add(vm); lua_pushboolean(vm, static_cast<int>(added)); return 1; } Userdata is bange::scene stored in Lua. Knowing that userdata is scene, in fact, the object's direction is the same when I've created the scene before. I need the reinterpret_cast, and then call the method. The pointer "this" is still the same direction inside the method. solved I did a small test in the bange::function constructor which works without problems. bange::function::function(){ string test("test"); this->functions["test"] = 2; } I finally noticed that the problem is bange::function *function = reinterpret_cast<bange::function *>(lua_touserdata(vm, 1)); because the object is bange::scene and no bange::function (i admit it, a pointer corruption) and this seems more a code design issue. So this, in a way, is solved. Thanks everybody.

  • Configure ApacheDS 1.5 with accessControlEnabled=true for authenticated access

    - by cmyers
    I need to set up an apacheDS instance. I am using standalone 1.5.5 on Linux. I have removed the example partition and added two of my own, each with their own suffixes. I have imported LDIFs for the two partitions and everything looks correct data-wise. I need to configure ApacheDS to disallow anonymous access. I was able to do that by following some of the directions here: http://directory.apache.org/apacheds/1.5/145-enable-and-disable-anonymous-access.html http://directory.apache.org/apacheds/1.5/32-basic-authorization.html Now only the administrator account (uid=admin,ou=system) can log in and make queries. I need to establish an admin account, and a "regular user" account which can read and write only certain entries within each partition. I tried to read the above docs and I got nuthin'. The second page "basic authorization" is completely incomprehensible to me. When I tried to add a "prescriptiveACI" to it using Apache Directory Studio, I get: Administration point 2.5.4.11=abc,2.5.4.10=efg does not contain an administrativeRole attribute! An administrativeRole attribute in the administrative point is required to add a subordinate subentry. where my partition is "ou=abc,o=def". I have no clue what is going on and the docs are really not helping, I am at a complete loss here. How can it possibly be this hard to just restrict access? P.S. can someone with proper rep please change the tag "apache" to the new tag "ApacheDS"?

  • Authentication required by wireless network.

    - by Roman
    I would like to use a wireless network from Ubuntu. In the network drop-down menu I select a network (this is a University network I have an account there). Then I get a windows with the following fields: Wireless Security: [WPA&WPA2 Enterprise] Authentication: [Tunneled TLS] Anonymous Identity: [] CA Certificate: [(None)] Inner Authentication: [some letters] User Name: [] Password: [] I put there my user name and password and do not change default value and leave "Anonymous Identity"blank. As a result of that I get "Authentication required by wireless network". How can I solve this problem? I think it is important to notice that our system administrator tried to find some files (which are probably needed to be used as "CA Certificate"). He said that he does not know where this file is located on Ubuntu (he support only Windows). So, probably this is direction I need to go. I need to find this file. But may be I am wrong. May be something else needs to be done. Could you pleas help me with that?

  • Biztalk 2009 logshipping with SQL 2008

    - by Manjot
    Hi, I am setting up biztalk logshipping for Biztalk 2009 database. Following http://msdn.microsoft.com/en-us/library/aa560961.aspx article, I am doing the following to setup biztalk logshipping on destination server: Enable Ad-hoc queries by: sp_configure 'show advanced options',1 go reconfigure go sp_configure 'Ad Hoc Distributed Queries',1 go reconfigure go sp_configure 'show advanced options',0 go reconfigure go Execute LogShipping_Destination_Schema & LogShipping_Destination_Logic in master on destinations server Run: exec bts_ConfigureBizTalkLogShipping @nvcDescription = '', @nvcMgmtDatabaseName = '', @nvcMgmtServerName = '', @SourceServerName = null, -- null indicates that this destination server restores all databases @fLinkServers = 1 -- 1 automatically links the server to the management database When I run this I am receiving the following error: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. After some research I found some info : Usually this error means that the SQL Server Service Principal Name (SPN) was not configured, and NTLM was not being used as an authentication mechanism. SQl services are runing under different domain accounts. So, I asked the domain admin to create SPNs for the servers, SQL service accounts for beoth source and destination using name and FQDN. enabled computer name and service accounts for delegation. When I run the following: select * from sys.dm_exec_connections I get the the same error: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON' Any help please?

  • PostgreSQL lots of large Arrays and Writes

    - by strife911
    Hi, I am running a python program that spawns 8 threads and as each thread launch its own postmaster process via psycopg2. This is to maximize the use of my CPU-cores (8). Each thread call a series of SQL Functions. Most of these functions go through many thousands of rows each associated to a large FLOAT8[] Array (250-300) values by using unnest() and multiplying each FLOAT8 by an another FLOAT8 associated to each row. This Array approach minimized the size of the Indexes and the Tables. The Function ends with an Insert into another Table of a row of the same form (pk INT4, array FLOAT8[]). Some SQL Functions called by python will Update a row of these kind of Tables (with large Arrays). Now I currently have configured PostgreSQL to use most of the memory for cache (effective_cache_size of 57 GB I think) and only a small amount of it for shared memory (1GB I think). First, I was wondering what the difference between Cache and Shared memory was in regards to PostgreSQL (and my application). What I have noticed is that only about 20-40% of my total CPU processing power is used during the most Read intensive parts of the application (Select unnest(array) etc). So secondly, I was wondering what I could do to improve this so that 100% of the CPU is used. Based on my observations, it does not seem to have anything to do with python or its GIL. Thanks

  • Exchange 2010 Mail Enabled Public Folder Unable to Recieve External (anon) e-mail.

    - by Alex
    Hello All, I am having issues with my "Public Folders" mail enabled folders receiving e-mails from external senders. The folder is setup with three Accepted Domains (names changed for privacy reasons): 1 - domain1.com (primary & Authoritative) 2 - domain2.com (Authoritative) 3 - domain3.com (Authoritative) When someone attempts to send an e-mail to [email protected] from inside the organization, the e-mail is received and placed in the appropriate folder. However, when someone tries to send an e-mail from outside the organization (such as a gmail account), the following error message is received: "Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 554 554 Recipient address rejected: User unknown (state 14)." When I try to send an e-mail to the same folder, using the same e-mail address above ([email protected]), but with domain2.com instead of domain3.com, it works as intended (both internal & external). I have checked, double checked, and triple checked my DNS settings comparing those from domain2 & domain3 with them both appearing identical. I have tried recreating the folders in question with the same results. I have also ran Get-PublicFolderClientPermission "\Web Programs\folder" with the following results for user anonymous: RunspaceId : 5ff99653-a8c3-4619-8eeb-abc723dc908b Identity : \Web Programs\folder User : Anonymous AccessRights : {CreateItems} Domain2.com & Domain3.com are duplicates of each other, but only domain2.com works as intended. All other exchange functions are functioning properly. If anyone out there has any suggestions, I would love to hear them. I've just hit a brick wall. Thanks for all your help in advance! --Alex
