  • Best practice- How to team-split a django project while still allowing code reusal

    - by Infinity
    I know this sounds kind of vague, but please let me explain- I'm starting work on a brand new project, it will have two main components: "ACME PRODUCT" (think Gmail, Meebo, etc), and "THE SITE" (help, information, marketing stuff, promotional landing pages, etc lots of marketing-induced cruft). So basically the url /acme/* will load stuff in the uber cool ajaxy application, and every other URI will load stuff in the other site. Problem: "THE SITE" component is out of my hands, and will be handled by a consultants team that will work closely with marketing, And I and my team will work solely on the ACME PRODUCT. Question: How to set up the django project in such a way that we can have: Seperate releases. (They can push new marketing pages and functionality without having to worry about the state of our code. Maybe even separate Subversion "projects") Minimize impact (on our product) of whatever flying-unicorns-hocus-pocus the other team codes into the site. Still allow some code reusal. My main concern is that the ACME product needs to be rock solid, and therefore needs to be somewhat isolated of whatever mistakes/code bloopers the consultants make in their marketing side of the site. How have you handled this? Any ideas? Thanks!

  • When using Direct3D, how much math is being done on the CPU?

    - by zirgen
    Context: I'm just starting out. I'm not even touching the Direct3D 11 API, and instead looking at understanding the pipeline, etc. From looking at documentation and information floating around the web, it seems like some calculations are being handled by the application. That, is, instead of simply presenting matrices to multiply to the GPU, the calculations are being done by a math library that operates on the CPU. I don't have any particular resources to point to, although I guess I can point to the XNA Math Library or the samples shipped in the February DX SDK. When you see code like mViewProj = mView * mProj;, that projection is being calculated on the CPU. Or am I wrong? If you were writing a program, where you can have 10 cubes on the screen, where you can move or rotate cubes, as well as viewpoint, what calculations would you do on the CPU? I think I would store the geometry for the a single cube, and then transform matrices representing the actual instances. And then it seems I would use the XNA math library, or another of my choosing, to transform each cube in model space. Then get the coordinates in world space. Then push the information to the GPU. That's quite a bit of calculation on the CPU. Am I wrong? Am I reaching conclusions based on too little information and understanding? What terms should I Google for, if the answer is STFW? Or if I am right, why aren't these calculations being pushed to the GPU as well?

  • Wordpress issue with footer

    - by Raelona
    I've been trying to turn my simple html/css site into a wordpress site. my big issue which no one seem to be able to solve appears in my footer. The footer is pretty much ignoring everything and just staying in the top of the site ( like it was a part of my header). All my files is split into 3 files. A header.php a footer.php and the page.php (one for each site). Header! <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" <?php language_attributes(); ?>> <head profile="http://gmpg.org/xfn/11"> <meta http-equiv="Content-Type" content="<?php bloginfo('html_type'); ?>; charset=<?php bloginfo('charset'); ?>" /> <?php if (is_search()) { ?> <meta name="robots" content="noindex, nofollow" /> <?php } ?> <title> <?php if (function_exists('is_tag') && is_tag()) { single_tag_title("Tag Archive for &quot;"); echo '&quot; - '; } elseif (is_archive()) { wp_title(''); echo ' Archive - '; } elseif (is_search()) { echo 'Search for &quot;'.wp_specialchars($s).'&quot; - '; } elseif (!(is_404()) && (is_single()) || (is_page())) { wp_title(''); echo ' - '; } elseif (is_404()) { echo 'Not Found - '; } if (is_home()) { bloginfo('name'); echo ' - '; bloginfo('description'); } else { bloginfo('name'); } if ($paged>1) { echo ' - page '. $paged; } ?> </title> <link rel="shortcut icon" href="/favicon.ico" type="image/x-icon" /> <link rel="stylesheet" href="<?php bloginfo('stylesheet_url'); ?>" type="text/css" /> <link rel="pingback" href="<?php bloginfo('pingback_url'); ?>" /> <?php if ( is_singular() ) wp_enqueue_script( 'comment-reply' ); ?> <?php wp_head(); ?> </head> <body <?php body_class(); ?>> <div id="Menu" ></div> <div id="Mainbody"> <div id="Portfolio"><a href="<?php echo get_option('home'); ?>"><?php bloginfo('name'); ?></a> </div> <div id="Slogan"><a href="index.html"><?php bloginfo('description'); ?></a></div> <div id="nav-menu"> <?php $defaults = array( 'theme_location' => '', 'menu' => '', 'container' => 'div', 'container_class' => 'menu-{menu slug}-container', 'container_id' => '', 'menu_class' => 'menu', 'menu_id' => '', 'echo' => true, 'fallback_cb' => 'wp_page_menu', 'before' => '', 'after' => '', 'link_before' => '', 'link_after' => '', 'items_wrap' => '<ul id="%1$s" class="%2$s">%3$s</ul>', 'depth' => 0, 'walker' => '' ); ?> <?php wp_nav_menu( $defaults ); ?> </div> <div class="Box"> <div id="Mainindhold"> page ! <?php get_header(); ?> <div id="Arbejde"> <h2>Uddrag af mine webdesigns</h2> <br /> <br /> <?php if (have_posts()) : while (have_posts()) : the_post(); ?> <?php $key='link'; $custom = get_post_meta($post->ID, $key, true); ?> <?php $key2='brugt'; $custom2 = get_post_meta($post->ID, $key2, true); ?> <?php $key3='linkexternal'; $custom3 = get_post_meta($post->ID, $key3, true); ?> <?php $billede = get_the_post_thumbnail($post->ID, 'full'); ?> <div class="Raekke"> <div class="Arbejds_Billede"> <a href="<?php echo $custom; ?>" rel="lightbox"> <?php print $billede; ?></a> </div> <div class="Arbejdsbeskrivelse"> <h3><?php the_title(); ?></h3> <?php the_content(); ?> <div id="program"> <img src="<?php echo $custom2; ?>" /> </div> <div class="Knap"><a href="<?php echo $custom3; ?>"><p>Besøg siden</p></a> </div> </div> </div> <div class="clear"></div> <?php endwhile; else: ?> <?php _e('No posts were fond.

  • Git repositories on shared hosting with ssh access - multiple users / one ssh account

    - by acp
    I'm part of a small team trying to start coding on a project. I've decided it's time to give git a chance (no more svn) and was trying to see if we could use our shared web hosting to deploy a "public" repository there so that we can easily push/pull to/from it and keep up-to-date with each others changes. The problem I'm having now is that we only have a single ssh account for that hosting. Having used svn in the past, I could enforce a svn username on a given pair of ssh keys, however I don't seem to be able to do something similar with git (in other words tie the ssh keypair to a specific dev). I don't mind everybody having read/write permissions everywhere, since anything that is private should stay on each others machine. Finally, solutions such as gitosis can not be used. I guess my question to you is how is accountability to git pushes given? Is it tied to the ssh account being used, or the email address given in git config? Can I create different ssh keys for every developer (for the same ssh account though), and just send them to the devs?

  • Translate Prototype code into Jquery version

    - by user1055495
    I everybody, I'm working on a SaaS application and I need to use Jquery instead of Prototype due to some extra plugins integration. My code that was wotking a charm with Prototype is not running anymore with Jquery and I'm not used to write in this framework... Is there someone to help me in "translating" this one: Thanks a lot for your help. var rates = new Array(); <% for tva_rate in @tva_rates -%> rates.push(new Array(<%= tva_rate.id %>, '<%=h tva_rate.taux %>', '<%=h tva_rate.compte_id %>' )); <% end -%> function tvaSelected() { tva_id = $('journal_tva_id').getValue(); show = 1; if (tva_id > 0){ rates.each(function(rate) { if (rate[0] == tva_id) { $('journal_taux').setValue(rate[1]); $('journal_compte_tva').setValue(rate[2]); show = 2; } }); } if (show == 1) { $('tva_taux_field').hide(); } else { $('tva_taux_field').show(); } } document.observe('dom:loaded', function() { tvaSelected(); $('journal_tva_id').observe('change', tvaSelected); });

  • jquery accessing dynamic class selectors

    - by dinotom
    Given the following html rendering; <fieldset id="fld_Rye"> <legend>7 Main St.</legend> <div> <table> <tr> <th class="wideCol"><b><i>Service Description</i></b></th> <th class="wideCol"><b><i>Service Name</i></b></th> <th class="normalPlusWidth"><b><i>Contact Name</i></b></th> </tr> <ItemTemplate> <tr class=""> <td class="servDesc">&nbsp;<b>Plumbing Services</b></td> <td class="servName">&nbsp;<b>Flynnsters's Plumbing</b></td> <td class="servContact">&nbsp;<b>Jim Flynnster</b></td> </tr> </ItemTemplate> I am trying to access all the td's with a class of servDesc, get their width into an array and get the max width from that array to reset the css width of that class using jquery on page load. I cant seem to get the right selector for those tags, and I've tried at least 50 variations. My latest try; var maxTdWidth; var servDescCols = []; $("#fld_Rye td#servDesc").each(function () { alert("found one"); servDescCols.push(this.width()); }); maxTdWidth = Math.max.apply(Math, servDescCols);

  • Object inside of array -- works in one scope but not in another?

    - by Earlz
    Ok I've been learning some of the more advanced aspects of Javascript and now trying to use this I'm stuck. Here is my code: function Data(){} function init(state){ var item; item=new Data(); item.fieldrid=17; item.description='foo'; state.push(item); }; function findInState(state,fieldrid) { for (var item in state) { alert(item.fieldrid); //prints undefined if (item.fieldrid == fieldrid) { return item; } } return null; } var s=[]; init(s); alert(s[0].fieldrid); //prints 17 (expected) alert(findInState(s,17).fieldrid); //exception here. function returns null. A running example is here at jsbin Why does this not work? I would expect the alert in findInState to yield 17 but instead it yields undefined. What am I doing wrong?

  • Tell bots apart from human visitors for stats?

    - by Pekka
    I am looking to roll my own simple web stats script. The only major obstacle on the road, as far as I can see, is telling human visitors apart from bots. I would like to have a solution for that which I don't need to maintain on a regular basis (i.e. I don't want to update text files with bot-related User-agents). Is there any open service that does that, like Akismet does for spam? Or is there a PHP project that is dedicated to recognizing spiders and bots and provides frequent updates? To clarify: I'm not looking to block bots. I do not need 100% watertight results. I just want to exclude as many as I can from my stats. In know that parsing the user-Agent is an option but maintaining the patterns to parse for is a lot of work. My question is whether there is any project or service that does that already. Bounty: I thought I'd push this as a reference question on the topic. The best / most original / most technically viable contribution will receive the bounty amount.

  • How to combine two separate unrelated Git repositories into one with single history timeline

    - by Antony
    I have two unrelated (not sharing any ancestor check in) Git repositories, one is a super repository which consists a number of smaller projects (Lets call it repository A). Another one is just a makeshift local Git repository for a smaller project (lets call it repository B). Graphically, it would look like this A0-B0-C0-D0-E0-F0-G0-HEAD (repo A) A0-B0-C0-D0-E0-F0-G0-HEAD (remote/master bare repo pulled & pushed from repo A) A1-B1-C1-D1-E1-HEAD (repo B) Ideally, I would really like to merge repo B into repo A with a single history timeline. So it would appear that I originally started project in repo A. Graphically, this would be the ideal end result A0-A1-B1-B0-D1-C0-D0-E0-F0-G0-E1-H(from repo B)-HEAD (new repo A) A0-A1-B1-B0-D1-C0-D0-E0-F0-G0-E1-H(from repo B)-HEAD (remote/master bare repo pulled & pushed from repo A) I have been doing some reading with submodules and subtree (Pro Git is a pretty good book by the way), but both of them seem to cater solution towards maintaining two separate branch with sub module being able to pull changes from upstream and subtree being slightly less headache. Both solution require additional and specialized git commands to handle check ins and sync between master and sub tree/module branch. Both solution also result in multiple time-lines (with --squash you even get 3 timelines with subtree). The closest solution from SO seems to talk about "graft", but is that really it? The goal is to have a single unified repository where I can pull/push check-ins, so that there are no more repo B, just repo A in the end.

  • General web service ideas

    - by user2014175
    I have a question regarding different types of web services. I'll preface this by saying that I have built a number of apps (for both ios and android) for personal use that interact with the web via php and sql. I have taught myself these languages, and as such don't have the broader background knowledge that many of you do. My question is, in what other ways can you perform an interaction between a web service and a mobile device other than mobile - php - sql - etc. For example, If I built a very simple tracking app for my car, my current method would be to push GPS coordinates from my iphone to my database at a set interval, then I would write a simple bit of javascript that pulled those coordinates out of the database and superimposed them on a google map. Is there a different way to do this? Such as the server acting as a live middle man who simple pushed the coordinates directly to a target browser? Without the database in the middle? If so, are there advantages and disadvantages to these different methods to achieve different goals? I know its a broad question but I'm really intrigued and I'm finding it difficult to word a google search for it. Any info / reading material suggesting would be excellent. Thanks

  • Perl TCP Server handling multiple Client connections

    - by Matt
    I'll preface this by saying I have minimal experience with both Perl and Socket programming, so I appreciate any help I can get. I have a TCP Server which needs to handle multiple Client connections simultaneously and be able to receive data from any one of the Clients at any time and also be able to send data back to the Clients based on information it's received. For example, Client1 and Client2 connect to my Server. Client2 sends "Ready", the server interprets that and sends "Go" to Client1. The following is what I have written so far: my $sock = new IO::Socket::INET { LocalHost => $host, // defined earlier in code LocalPort => $port, // defined earlier in code Proto => 'tcp', Listen => SOMAXCONN, Reuse => 1, }; die "Could not create socket $!\n" unless $sock; while ( my ($new_sock,$c_addr) = $sock->accept() ) { my ($client_port, $c_ip) = sockaddr_in($c_addr); my $client_ipnum = inet_ntoa($c_ip); my $client_host = ""; my @threads; print "got a connection from $client_host", "[$client_ipnum]\n"; my $command; my $data; while ($data = <$new_sock>) { push @threads, async \&Execute, $data; } } sub Execute { my ($command) = @_; // if($command) = "test" { // send "go" to socket1 print "Executing command: $command\n"; system($command); } I know both of my while loops will be blocking and I need a way to implement my accept command as a thread, but I'm not sure the proper way of writing it.

  • Creating rapid function overloads in C++

Any way to do this faster?

  • How can I qualify an autowired property with a variable from a config file using annotations?

    - by jiggy
    My specific problem is that I have configured two beans that implement the same interface and I have a third bean that has a property of that interface's type. I inject the property using a config property. So, assuming RemoteDataSource and LocalDataSource implement IDataSource and dao1 has a property of type IDataSource, my XML config might look like this: <bean id="datasource1" class="com.foo.RemoteDataSource"> <property name="url">${url}</property> </bean> <bean id="datasource2" class="com.foo.LocalDataSource"> <property name="path">${filepath}</property> </bean> <bean id="dao1" class="com.foo.MyDAO"> <property name="dataSource">${datasource}</property> </bean> With url, filepath and datasource being defined in an included properties file. We are now making a push for annotation-driven configuration and I'm not sure how to annotate my dao to put the data source configured in the property file. I want to do something like this, but it is evidently not allowed: @Autowired @Qualifier("${datasource}") public void setDataSource(IDataSource datasource) {...}

  • Python programming - Windows focus and program process

    - by Zack
    I'm working on a python program that will automatically combine sets of files based on their names. Being a newbie, I wasn't quite sure how to go about it, so I decided to just brute force it with the win32api. So I'm attempting to do everything with virtual keys. So I run the script, it selects the top file (after arranging the by name), then sends a right click command,selects 'combine as adobe PDF', and then have it push enter. This launched the Acrobat combine window, where I send another 'enter' command. The here's where I hit the problem. The folder where I'm converting these things loses focus and I'm unsure how to get it back. Sending alt+tab commands seems somewhat unreliable. It sometimes switches to the wrong thing. A much bigger issue for me.. Different combination of files take different times to combine. though I haven't gotten this far in my code, my plan was to set some arbitrarily long time.sleep() command before it finally sent the last "enter" command to finish and confirm the file name completing the combination process. Is there a way to monitor another programs progress? Is there a way to have python not execute anymore code until something else has finished?

  • Booking logic and architecture, database sync: Hotels, tennis courts reservation system ...

    - by coulix
    Hello Stackers, Imagine that you want to design a tennis booking system. You have 5 tennis clubs as partenrs with no online api allowing you to check on their side if a court is booked or not: You have to build this part as well. Every time a booking is done on their side you want it to be know by our system. Probably using a POST request form tennis partner to our server. Every time a booking is done on our website, we want to push the booking to their system. The difficulty is that their system need to be online and accessible from outside. Ip may change, we have to use a dns updater. In case their system is not available we still accept the booking and fallback to an async email with 'i confirm booking/reject booking' link sent to the club. I find the whole process quite complex and was wondering about the way online hotel booking system and hotel were working. Do they all have their data open and online ? The good thing is that the data will grow large and fits nicely to some no SQL ;) like couch db

  • C++: inheritance problem

    - by Helltone
    It's quite hard to explain what I'm trying to do, I'll try: Imagine a base class A which contains some variables, and a set of classes deriving from A which all implement some method bool test() that operates on the variables inherited from A. class A { protected: int somevar; // ... }; class B : public A { public: bool test() { return (somevar == 42); } }; class C : public A { public: bool test() { return (somevar > 23); } }; // ... more classes deriving from A Now I have an instance of class A and I have set the value of somevar. int main(int, char* []) { A a; a.somevar = 42; Now, I need some kind of container that allows me to iterate over the elements i of this container, calling i::test() in the context of a... that is: std::vector<...> vec; // push B and C into vec, this is pseudo-code vec.push_back(&B); vec.push_back(&C); bool ret = true; for(i = vec.begin(); i != vec.end(); ++i) { // call B::test(), C::test(), setting *this to a ret &= ( a .* (&(*i)::test) )(); } return ret; } How can I do this? I've tried two methods: forcing a cast from B::* to A::*, adapting a pointer to call a method of a type on an object of a different type (works, but seems to be bad); using std::bind + the solution above, ugly hack; changing the signature of bool test() so that it takes an argument of type const A& instead of inheriting from A, I don't really like this solution because somevar must be public.

  • custom *arbitrary* TemplateField definitions

    - by end-user
    I'm building a GridView on the fly, and I'd like to pre-define the TemplateFields to be included ondemand. So, what I'd like to do is have a declarative file that defines how the different templates look for a specific column. Like: <asp:TemplateField> <HeaderTemplate> this is a text column </HeaderTemplate> <ItemTemplate> data goes here </ItemTemplate> <EditItemTemplate> <asp:TextBox Text="databindhere" /> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> this is a bool column </HeaderTemplate> <ItemTemplate> if(true) "yes" else "no" </ItemTemplate> <EditItemTemplate> <asp:CheckBox Checked="databindme" /> </EditItemTemplate> </asp:TemplateField> So, if my query had a text and two bool fields, I could push the appropriate TemplateFields in the the Columns property as needed. (I hope I'm making sense here) So, how would I go about creating declarative files for the above definitions? And then, how would I reference those definitions programmatically?

  • Display latest date from a HTML attribute

    - by Tron
    I currently have several classes which contain a date inside an attribute. <div id="container"> <div class="date" date="19/11/2013"></div> <div class="date" date="06/11/2013"></div> </div> <div id="result"></div> What I would like to do, is find the latest date and display it on the page. So far, I've found the information in the attribute, checked that it doesn't exist in the array then and pushed it into an array. I'm not entirely sure of the best approach from here, but ideally i would like to find the latest date and then append it to the results container. $('.date').each(function () { var dateArray = []; var date = $(this).attr('date'); if ($.inArray(date, dateArray) == -1) { dateArray.push(date); } $('#result').append(dateArray); }); Any assistance on the above would be greatly appreciated. Thanks :)

  • callback on a variable which is inside a .each() loop

    - by Stoic
    I have this function, which is doing an asynchronous call to FB.api method. Now, i am looping over some data and capturing result of the above method call successfully. However, I am using a .each loop and I really can not figure out how to place my callback in this method, so that the outer method is only executed once. Here are the functions I am using: ask_for_perms($(this).val(),function(result) { $('#some-div').html('<a onclick = "get_perms(result);" >get perms</a>'); }); function ask_for_perms(perms_requested,cb) { var request = []; $.each(perms_requested,function(i,permission) { FB.api({ method: 'users.hasAppPermission', ext_perm: permission }, function(response) { if (response == 0) request.push(permission); request.join(','); cb(request); // cb is called many times here. }); }); } I am trying to return the request string from ask_for_perms function. Can anyone suggest me on where to place a proper callback to ask_for_perms. Right now, however, it works for me, but the callback is being called many times since it is inside a for loop. referencing: returning a variable from the callback of a function

  • When to save a mongoose model

    - by kentcdodds
    This is an architectural question. I have models like this: var foo = new mongoose.Schema({ name: String, bars: [{type: ObjectId, ref: 'Bar'}] }); var FooModel = mongoose.model('Foo', foo); var bar = new mongoose.Schema({ foobar: String }); var BarModel = mongoose.model('Bar', bar); Then I want to implement a convenience method like this: BarModel.methods.addFoo = function(foo) { foo.bars = foo.bars || []; // Side note, is this something I should check here? foo.bars.push(this.id); // Here's the line I'm wondering about... Should I include the line below? foo.save(); } The biggest con I see about this is that if I did include foo.save() then I should pass in a callback to addFoo so I avoid issues with the async operation. I'm thinking this is not preferable. But I also think it would be nice to include because addFoo hasn't really "addedFoo" until it's been saved... Am I breaking any design best practices doing it either way?

    - by rramsden
    I'm trying to close a socket after a connection times out after 1000ms. I am able to set a timeout that gets triggered after a 1000ms but I can't seem to destroy the socket... any ideas? var connection = http.createClient(80, 'localhost'); var request = connection.request('GET', '/somefile.xml', {'host':'localhost'}); var start = new Date().getTime(); request.socket.setTimeout(1000); request.socket.addListener("timeout", function() { request.socket.destroy(); sys.puts("socket timeout connection closed"); }); request.addListener("response", function(response) { var responseBody = []; response.setEncoding("utf8"); response.addListener("data", function(chunk) { sys.puts(chunk); responseBody.push(chunk); }); response.addListener("end", function() { }); }); request.end(); returns socket timeout connection closed node.js:29 if (!x) throw new Error(msg || "assertion error"); ^ Error: assertion error at node.js:29:17 at Timer.callback (net:152:20) at node.js:204:9

  • Getting memory leak at NSURL connection in Iphone sdk.

    - by monish
    Hi guys, Here Im getting leak at the NSURL connection in my libxml parser can anyone tell how to resolve it. The code where leak generates is: - (BOOL)parseWithLibXML2Parser { BOOL success = NO; ZohoAppDelegate *appDelegate = (ZohoAppDelegate*) [ [UIApplication sharedApplication] delegate]; NSString* curl; if ([cName length] == 0) { curl = @"https://invoice.zoho.com/api/view/settings/currencies?ticket="; curl = [curl stringByAppendingString:appDelegate.ticket]; curl = [curl stringByAppendingString:@"&apikey="]; curl = [curl stringByAppendingString:appDelegate.apiKey]; curl = [curl stringByReplacingOccurrencesOfString:@"\n" withString:@""]; } NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:curl]]; NSLog(@"the request parserWithLibXml2Parser %@",theRequest); NSURLConnection *con = [[[NSURLConnection alloc] initWithRequest:theRequest delegate:self] autorelease];//Memory leak generated here at this line of code. //self.connection = con; //[con release]; // This creates a context for "push" parsing in which chunks of data that are // not "well balanced" can be passed to the context for streaming parsing. // The handler structure defined above will be used for all the parsing. The // second argument, self, will be passed as user data to each of the SAX // handlers. The last three arguments are left blank to avoid creating a tree // in memory. _xmlParserContext = xmlCreatePushParserCtxt(&simpleSAXHandlerStruct, self, NULL, 0, NULL); if(con != nil) { do { [[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]]; } while (!_done && !self.error); } if(self.error) { //NSLog(@"parsing error"); [self.delegate parser:self encounteredError:nil]; } else { success = YES; } return success; } Anyone's help will be muck appreciated . Thank you, Monish.

  • Are vector assignments copied by value or by reference in Google's Go language?

    - by Brian T Hannan
    In the following code, I create one peg puzzle then do a move on it which adds a move to its movesAlreadyDone vector. Then I create another peg puzzle then do a move on it which adds a move to its movesAlreadyDone vector. When I print out the values in that vector for the second one, it has the move in it from the first one along with the move from the second one. Can anyone tell me why it seems to be assigning by reference and not value? Are vector assignments copied by value or by reference in Google's Go language? package main import "fmt" import "container/vector" type Move struct { x0, y0, x1, y1 int } type PegPuzzle struct { movesAlreadyDone * vector.Vector; } func (p *PegPuzzle) InitPegPuzzle(){ p.movesAlreadyDone = vector.New(0); } func NewChildPegPuzzle(parent *PegPuzzle) *PegPuzzle{ retVal := new(PegPuzzle); retVal.movesAlreadyDone = parent.movesAlreadyDone; return retVal } func (p *PegPuzzle) doMove(move Move){ p.movesAlreadyDone.Push(move); } func (p *PegPuzzle) printPuzzleInfo(){ fmt.Printf("-----------START----------------------\n"); fmt.Printf("moves already done: %v\n", p.movesAlreadyDone); fmt.Printf("------------END-----------------------\n"); } func main() { p := new(PegPuzzle); cp1 := new(PegPuzzle); cp2 := new(PegPuzzle); p.InitPegPuzzle(); cp1 = NewChildPegPuzzle(p); cp1.doMove(Move{1,1,2,3}); cp1.printPuzzleInfo(); cp2 = NewChildPegPuzzle(p); cp2.doMove(Move{3,2,5,1}); cp2.printPuzzleInfo(); } Any help will be greatly appreciated. Thanks!
