• Poll: Require Semicolons and Forbid Tables?

  - by George Bailey

  There are a few very serious but opinionated and subjective arguments that I know of. Two of them are Whether or not to use semicolons in the event they are optional. There is a vote as here that also includes reasons Whether or not to use tables for non tabular data. There more information here Since the semicolon question arises often in JavaScript and the tables thing in HTML then there are probably many who run into both. I sort of expect a person who is strict with semicolons also to be strict about avoiding tables. I will post four CW answers here to vote on. Please vote what you think is right. If you want to talk about the reasons then please use Semicolons: Do you recommend using semicolons after every statement in JavaScript? Tables: Start your own question under the polls tag and follow the design of the semicolons question.

• Send C++ Structure to MSMQ Message

  Hi, I am trying to send the below structure through MSMQ Message typedef struct { char cfiller[7]; short MsgCode; char cfiller1[11]; short MsgLength; char cfiller2[2]; } MESSAGECODE; typedef struct { MESSAGECODE Header; char DealerId[16]; char GroupId[16]; long Token; short Periodicity; double Deposit; double GrossExposureLimit; double NetExposureLimit; double NetSaleExposureLimit; double NetPositionLimit; double TurnoverLimit; double PendingOrdersLimit; double MTMLossLimit; double MaxSingleTransValue; long MaxSingleTransQty; double IMLimit; long NetQuantityLimit; } LIMITUPDATE; void main() { // // create queue // open queue // send message // OleInitialize(NULL); // have to init OLE // // declare some variables // IMSMQQueueInfoPtr qinfo("MSMQ.MSMQQueueInfo"); IMSMQQueuePtr qSend; IMSMQMessagePtr m("MSMQ.MSMQMessage"); LIMITUPDATE l1; l1.Header.MsgCode=26001; l1.Header.MsgLength=150; qinfo->PathName = ".\\private$\\q99"; m->Body = l1; qSend = qinfo->Open(MQ_SEND_ACCESS, MQ_DENY_NONE); m->Send(qSend); qSend->Close(); } while compiling i am getting the following error.

• Shader vs Shader Material , papervision specific , general insight welcome.

  - by RadAdam

  hello overflow. I asked this question on the pv3d forum and not a single person could, or cared to answer it. Im relatively new to 3d so i apologize if this is common sense to some. I have a sphere , in which i am applying a CellMaterial to. Looks great. I noticed that in the papervision sdk , there is also a CellShader. Should I be using this in congruence with the CellMaterial ? Should it be one or the other ? Is shader , a deprecated practice to Shader Material ? My initial thoughts were that the shader applies to the whole scene , while materials can be applied uniquely to objects. The documentation seems to show otherwise. What benefit if any could be gained by using both a CellShader and a CellMaterial ? id really love to get some ambient inclusion in there some how.

• Dot Game and Dynamic Programming

  - by Albert Diego

  I'm trying to solve a variant of the dot game with dynamic programming. The regular dot game is played with a line of dots. Each player takes either one or two dots at their respective end of the line and the person who is left with no dots to take wins. In this version of the game, each dot has a different value. Each player takes alternate turns and takes either dot at either end of the line. I want to come up with a way to use dynamic programming to find the max amount that the first player is guaranteed to win. I'm having problems grasping my head around this and trying to write a recurrence for the solution. Any help is appreciated, thanks!

• Why avoid pessimistic locking in a version control system?

  - by raven

  Based on a few posts I've read concerning version control, it seems people think pessimistic locking in a version control system is a bad thing. Why? I understand that it prevents one developer from submitting a change while another has the file checked out, but so what? If your code files are so big that you constantly have more than one person working on them at the same time, I submit that you should reorganize your code. Break it up into smaller functional units. Integration of concurrent code changes is a tedious and error-prone process even with the tools a good version control system provides to make it easier. I think it should be avoided if at all possible. So, why is pessimistic locking discouraged?

• No Debug information of an iPhone app

  - by Markus Pilman

  Hi all, I wrote an iPhone app which uses a third party library. I crosscompiled this library successfully and everything works smoothly. But when I want to debug the application, it would make sense to also be able to debug the library. So I compiled also the external library with debuging information (usign the gcc option -ggdb). But when I want to debug it, I get the correct symbol names, but the positions are always wrong/extremly wierd (locale_facets.tcc:2505 or iostream:76). For example a stack trace could look like this: #0 0x000045e8 in zorba::serialization::SerializeBaseClass::SerializeBaseClass () at iostream:76 #1 0x0001d990 in zorba::RCObject::RCObject () at iostream:76 #2 0x00025187 in zorba::xqpStringStore::xqpStringStore () at iostream:76 #3 0x000719e4 in zorba::String::String () at locale_facets.tcc:2505 #4 0x00030513 in iphone::iLabelModule::getURI (this=0x533f710) at /Users/sausalito/eth/izorba/sandbox/ilabel.cpp:19 #5 0x00356766 in zorba::static_context::bind_external_module () at locale_facets.tcc:2505 #6 0x0006139d in zorba::StaticContextImpl::registerModule () at locale_facets.tcc:2505 #7 0x000333e5 in -[ZorbaCaller init] (self=0x53405c0, _cmd=0x95583398) at /Users/sausalito/eth/izorba/sandbox/ZorbaCaller.mm:61 #8 0x00033180 in +[ZorbaCaller instance] (self=0x11dc2bc, _cmd=0x93679591) at /Users/sausalito/eth/izorba/sandbox/ZorbaCaller.mm:37 #9 0x0003d998 in -[testOne execute:] (self=0x530d560, _cmd=0x9366b126, sender=0x5121da0) at /Users/sausalito/eth/izorba/sandbox/generator/testOne.mm:13 #10 0x01a21405 in -[UIApplication sendAction:to:from:forEvent:] () #11 0x01a84b4e in -[UIControl sendAction:to:forEvent:] () #12 0x01a86d6f in -[UIControl(Internal) _sendActionsForEvents:withEvent:] () #13 0x01a85abb in -[UIControl touchesEnded:withEvent:] () #14 0x01a3addf in -[UIWindow _sendTouchesForEvent:] () #15 0x01a247c8 in -[UIApplication sendEvent:] () #16 0x01a2b061 in _UIApplicationHandleEvent () #17 0x03b6fd59 in PurpleEventCallback () #18 0x034a8b80 in CFRunLoopRunSpecific () #19 0x034a7c48 in CFRunLoopRunInMode () #20 0x03b6e615 in GSEventRunModal () #21 0x03b6e6da in GSEventRun () #22 0x01a2bfaf in UIApplicationMain () #23 0x0002dd7e in main (argc=1, argv=0xbffff044) at /Users/sausalito/eth/izorba/sandbox/main.m:16 Does anybody have an idea, where these wrong locations come from?

• C++ Pointer member function with templates assignment with a member function of another class

  - by Agusti

  Hi, I have this class: class IShaderParam{ public: std::string name_value; }; template<class TParam> class TShaderParam:public IShaderParam{ public: void (TShaderParam::*send_to_shader)( const TParam&,const std::string&); TShaderParam():send_to_shader(NULL){} TParam value; void up_to_shader(); }; typedef TShaderParam<float> FloatShaderParam; typedef TShaderParam<D3DXVECTOR3> Vec3ShaderParam; In another class, I have a vector of IShaderParams* and functions that i want to send to "send_to_shader". I'm trying assign the reference of these functions like this: Vec3ShaderParam *_param = new Vec3ShaderParam; _param-send_to_shader = &TShader::setVector3; This is the function: void TShader::setVector3(const D3DXVECTOR3 &vec, const std::string &name){ //... } And this is the class with IshaderParams*: class TShader{ std::vector params; public: Shader effect; std::string technique_name; TShader(std::string& afilename):effect(NULL){}; ~TShader(); void setVector3(const D3DXVECTOR3 &vec, const std::string &name); When I compile the project with Visual Studio C++ Express 2008 I recieve this error: Error 2 error C2440: '=' :can't make the conversion 'void (__thiscall TShader::* )(const D3DXVECTOR3 &,const std::string &)' a 'void (__thiscall TShaderParam::* )(const TParam &,const std::string &)' c:\users\isagoras\documents\mcv\afoc\shader.cpp 127 Can I do the assignment? No? I don't know how :-S Yes, I know that I can achieve the same objective with other techniques, but I want to know how can I do this..

• Comment out a python code block

  - by gbarry

  Is there any mechanism to comment out large blocks of Python code? Right now the only ways I can see of commenting out code are to either start every line with a #, or to enclose the code in """ (triple quotes), except that actually makes it show up in various doc tools. Edit--After reading the answers (and referring to the "duplicate"), I have concluded the correct answer is "No". One person said so, and the rest lectured us about editors. Not a bad thing, but I feel it's important to put the answer at the top.

• How RPG characters are made

  - by user365314

  If RPG with the ability to change armors and clothes are made, how is it done? I mean the 3d side mostly If i make normal character, that has flat clothes, it would be easy, just change textures, but question is about armors, which have totally different models. So are only armor models recreated or character model with armor? How is it imported into game engine, only armor or character model with new armor? If person changes armor in game, will game swap the hole model or only the armor part? if only the armor part, then how the movement animations are done, are armor models animated on characters in 3d programs or what... :D

• Best way to store data for Greasemonkey based crawler?

  - by Björn

  I want to crawl a site with Greasemonkey and wonder if there is a better way to temporarily store values than with GM_setValue. What I want to do is crawl my contacts in a social network and extract the Twitter URLs from their profile pages. My current plan is to open each profile in it's own tab, so that it looks more like a normal browsing person (ie css, scrits and images will be loaded by the browser). Then store the Twitter URL with GM_setValue. Once all profile pages have been crawled, create a page using the stored values. I am not so happy with the storage option, though. Maybe there is a better way? I have considered inserting the user profiles into the current page so that I could all process them with the same script instance, but I am not sure if XMLHttpRequest looks indistignuishable from normal user initiated requests.

• Teaching a mainframe COBOL programmer Java?

  - by Jared

  I’m trying to help someone learn Java who’s only programming experience is COBOL on the mainframe. I was wondering if anyone knew any good resources for object oriented concepts. I learned how to program with C++ so just understand the theory behind basic OOP. I’m more concerned about a way to get the basic concepts across, such as encapsulation and inheritance rather then Java syntax. I think it’d be better to teach the concepts of OOP then a language rather then trying to cram both a new language and paradigm in at the same time. Does anyone have any resources or ideas that could help this person learn OOP followed by Java?

• Low-level Keyboard Hooks/SendInput with Winkey+L possible? (workstation lockout is intercepted in Vi

  - by Brian Jorgensen

  I work on a project called UAWKS (Unofficial Apple Wireless Keyboard Support) that helps Windows users use Apple's bluetooth keyboard. One of the main goals of UAWKS is to swap the Cmd key (which behaves as Winkey in Windows) with Ctrl, allowing users to do Cmd+C for copy, Cmd+T for new tab, etc. It is currently developed using AutoHotkey, which worked pretty well under Windows XP. However, on Vista and Windows 7, Cmd+L causes problems: Regardless of low-level keyboard hooks, Winkey+L is always intercepted by Windows and normally locks the workstation... You can disable workstation locking with this registry hack, but pressing Winkey+L still can't be rebound in AHK Pressing Winkey+L leaves Winkey in the Keydown state until the next (additional) Winkey Up. Simulating a Keyup event doesn't seem to work either! It seems that Winkey+L is a special chord that messes everything else up. I've looked through the AHK source code, and they try to address this problem in SendKey() in keyboard_mouse.cpp (near line 883 in v1.0.48.05), but it doesn't work. I wrote up my own low-level keyboard hook application in C#, and I see the same problem. Has anyone else run into this? Is there a workaround?

• How to merge/crosslink Javadoc?

  - by Tom Wheeler

  If you have the standard Javadoc for a few different projects, how can you process them to create a single unified set of documentation in which everything is cross-linked? Ideally, the result would be similar to the documentation for the various modules in the NetBeans Platform: http://bits.netbeans.org/dev/javadoc/index.html but I've looked at their build scripts and they're predicated on you building everything from source. I'm looking for something which could also handle linking in Javadoc for third-party libraries, so I'd imagine it would need to be a post-processing operation. I can't be the first person to ever want this. Any ideas?

• Linked List push()

  - by JKid314159

  The stack is initialized with a int MaxSize =3. Then I push one int onto the list. " Pushed:" is returned to the console. Program crashes here. I think my logic is flawed but unsure. Maybe an infinite loop or unmet condition? Thanks for your help. I'm trying to traverse the list to the last node in the second part of the full() method. I implemented this stack as array based so must implement this method full() as this method is inside of main class. while(!stacker.full()) { cout << "Enter number = "; cin >> intIn; stacker.push(intIn); cout << "Pushed: " << intIn << endl; }//while Call to LinkListStack.cpp to class LinkList full(). int LinkList::full() { if(head == NULL) { top = 0; } else { LinkNode * tmp1; LinkNode * tmp2; tmp1 = head; while(top != MaxSize) { if(tmp1->next != NULL){ tmp2 = tmp1->next; tmp1 = tmp2; ++top; }//if }//while }//else return (top + 1 == MaxSize); }

• How do I add multiple joins (Fetches) to a joined table using nhibernate and LINQ ?

  - by ooo

  i have these tables /entities VacationRequestDate table which has a VacationRequestId field that links with VacationRequest table VacationRequest has PersonId and RequestStatusId fields that links with Person and RequestStatus respectively. i have this query so far: IEnumerable<VacationRequestDate> dates = Session.Query<VacationRequestDate>().Fetch(r => r.VacationRequest).ThenFetch(p=>p.RequestStatus).ToList(); this works fine and joins with VacationRequest and then VacationRequest joins with RequestStatus but i can't figure out how to add an additional EAGER join to the VacationRequest table. If i add a Fetch at the end, it refers to the VacationRequestDate table If i add a ThenFetch at the end, it refers to the RequestStatus table I can't find any api that will refer to the VacationRequest table as the reference point. how would you add multiple joins to a joined table using nhibernate LINQ ?

• How secure is a PostgreSQL database if my server is stolen?

  - by orokusaki

  If I have a server with a database if top secret data in PostgreSQL and my password is practically impossible to crack (128 character string of all sorts of weird chars, generated by hand). The server password is also uncrackable in theory (basically, ignore the possibility of a password crack on the DB). Aside from a password crack, how easy is it to get the data out of this database? Assumptions: Only the DB exists on the server. There is no password in a PHP script or anything like that The person who has the server is a computer / DB / hard-drive recovery expert I'm not using any hard-drive encryption or anything out of the norm for protection I'm trying to understand the risks involved with somebody gaining physical access to my server's hard-drives.

• who wrote 250k tests for webkit?

  - by amwinter

  assuming a yield of 3 per hour, that's 83000 hours. 8 hours a day makes 10,500 days, divide by thirty to get 342 mythical man months. I call them mythical because writing 125 tests per person per week is unreal. can any wise soul out there on SO shed some light on what sort of mythical men write unreal quantities of tests for large software projects? thank you. update chrisw thinks there are only 20k tests (check out his explanation below). PS I'd really like to hear from folks who have worked on projects with large test bases

• What's the best technology for a medium complexity web application?

  - by naveed

  I'm planning to work on a web application of reasonable complexity and am wondering what technology to go with. It will probably start with one person, but there will be 2 or 3 more eventually. My first requirement is to be able to do this as quickly as possible - preferably with as less code as possible. Secondly requirement is that it should be able to scale easily. I have worked with .NET and PHP. So, I am thinking about ASP .NET MVC or CakePHP. It appears to me that CakePHP might be quicker. I did look at Ruby on Rails, but the learning curve is a little steep (which is not an issue if I can be convinced that this is the best tool for the task), I'm not too crazy about the huge number of files generated and I have heard about scalability issues as well as it's applicability to complex situations. I look forward to your opinions on your favorite technology and why.

• How to implement file transfer with Java sockets?

  - by ZeKoU

  Hello, I am working on a chat implementation with Java sockets. I have focused on few functionalities, like authentication, one person chat and a group chat. I was thinking about adding file transfer functionality, and I wonder what's the good practice about this. Should I have separate socket on the server with different port listening just for file transfers? Right now input and output streams that I get from server socket are binded to Scanner and PrintWriter objects respectively, so I find it hard to use that for file transfer. Any patterns you guys could recommend or give me good recommendations are very appreciated. Thanks, ZeKoU

• django getting current user id

  - by dana

  hello, i have a mini app where users can login, view their profile, and follow each other. 'Follow' is a relation like a regular 'friend' relationship in virtual communities, but it is not necessarily reciprocal, meaning that one can follow a user, without the need that the user to be following back that person who follows him. my problem is: if i am a logged in user, and i navigate to a profile X, and push the button follow, how can i take the current profile id ?(current profile meaning the profile that I, the logged in user, am viewing right now.) the view: def follow(request): if request.method == 'POST': form = FollowForm(request.POST) if form.is_valid(): new_obj = form.save(commit=False) new_obj.initiated_by = request.user u = User.objects. what here? new_obj.follow = u new_obj.save() return HttpResponseRedirect('.') else: form = FollowForm() return render_to_response('followme/follow.html', { 'form': form, }, context_instance=RequestContext(request)) thanks in advance!

• Is it possible to change 2-3 times f->SetSensor() ?

  - by Asen

  Hello there ! i use cocos2d-iphone-0.99.2 and integrated in it box2d. i have 2 kind of sprites with tags 1 and 2. Also i created bodies and shape definitions for them. what i'm trying to do is to make sprite1 kinds to act as solid or act as not solid when sprite2 colides with them. i tried this code : for(b2Body *b = _world->GetBodyList(); b; b=b->GetNext()) { if (b-GetUserData() != NULL) { CCSprite *sprite = (CCSprite )b-GetUserData(); if (sprite.tag == 1) { b2Fixture f = b-GetFixtureList(); f-SetSensor(solid); } } } Where solid is bool. The first time when i change fixture to sensor everything is just fine but when i try to revert and change again to solid my app crashes with the following error : Assertion failed: (manifold-pointCount 0), function b2ContactSolver, file /Documents/myapp/libs/Box2D/Dynamics/Contacts/b2ContactSolver.cpp, line 58. Is it possible somehow to change fixture-SetSensor several times and if so ... how ? Any help is highly appreciated.

• How to extract ALL typedefs and structs and unions from c++ source

  - by Michael Wells

  I have inherited a Visual Studio project that contains hundreds of files. I would like to extract all the typedefs, structs and unions from each .h/.cpp file and put the results in a file). Each typdef/struct/union should be on one line in the results file. This would make sorting much easier. typdef int myType; struct myFirstStruct { char a; int b;...}; union Part_Number_Serial_Number_Part_2_Response_Message_Type {struct{Message_Response_Head_Type Head; Part_Num_Serial_Num_Part_2_Report_Array Part_2_Report; Message_Tail_Type Tail;} Data; BYTE byData[140];}myUnion; struct { bool c; int d;...}mySecondStruct; My problem is, I do not know what to look for (grammar of typedef/structs/unions) using a regular expression. I cannot believe that nobody has done this before (I googled and have not found anything on this). Does anyone know the regular expressions for these? (Note some are commented out using // others /* */) Or a tool to accomplish this. Edit: I am toying with the idea of autogenerating source code and/or dialogs for modifying messages that use the underlying typedef/struct/union. I was going to use the output to generate an XML file that could be used for this reason. The source for these are in C/C++ and used in almost all my projects. These projects are usually NOT in C/C++. By using the XML version I would only need to update/add the typedef/struct/union only in one place and all the projects would be able to autogen the source and/or dialogs.

• How to determine if birthday or anniversary occured during date range

  - by davekaro

  Given I have a birthday/anniversary DateTime, how can I determine if that date occurred during a specific date range? For example, Birthday = 1/2/2000 Date Range = 12/25/2008 - 1/3/2009 I need a method to determine whether or not this person's birthday happened during that date range - preferably in C#. I first went about changing the year of the birthday DateTime to match the date range, then just check if the "new" birthday DateTime is between the start and end date of the date range... but when the date range spans different years, like in my example above - I had to add a nasty if statement. Is there no better way?
