• Do there any dev who wrote iPhone wifi/bluetooth multiplay before?

  - by Jerry1923

  Hi there, do there any dev who wrote iPhone wifi/bluetooth multiplay before? Recently, I'm trying to make my latest game Doodle Kart to have mulityplay via bluetooth. But I found that there are hugh data need to share between the 2 devices. -your car's position and direction -your car's status(it is in normal state, it is hitting by bullet, it is falling into to hole....) -CUP car's position, dicretion, and their status -items position and status (pencil, bullet...) I'm thinking about one device calculate all the things, and the other device just wait and receive the data to display on the screen. Does it make sense? Hey, I should ask you the most important question first: Do you think it's possible to make bluetooth multiplay work on my game? It's just too much data need to share between the device.

• How do I escape a string for a shell command in nodejs (V8 Javascript engine)?

  - by Maciek

  In nodejs, the only way to execute external commands is via sys.exec(cmd). I'd like to call an external command and give it data via stdin. In nodejs there does yet not appear to be a way to open a command and then push data to it (only to exec and receive its standard+error outputs), so it appears the only way I've got to do this right now is via a single string command such as: var dangerStr = "bad stuff here"; sys.exec("echo '" + dangerStr + "' | somecommand"); Most answers to questions like this have focused on either regex which doesn't work for me in nodejs (which uses Google's V8 Javascript engine) or native features from other languages like Python. I'd like to escape dangerStr so that it's safe to compose an exec string like the one above. If it helps, dangerStr will contain JSON data.

• Flush() not working in drupal

  - by fawad

  I'm trying to post data from one node to another. The other node contains the for loop which iterates for long time and finally generates the table. I want to display the result after each iteration. I have tried to put "flush();" but it is not working. What should i do to display each iteration result on the node page? Note: If i do it with ob_flush() it works but it then starts printing data above the header which is not suitable. I want all the data inside the node.

• Insert objects into a collection with LINQ based on a property of the existing objects in the collection

  - by DavidS

  Hi, I've got a collection of object which contains data as follows: FromTime Duration 2010-12-28 24.0000 2010-12-29 24.0000 2010-12-30 24.0000 2010-12-31 22.0000 2011-01-02 1.9167 2011-01-03 24.0000 2011-01-04 24.0000 2011-01-05 24.0000 2011-01-06 24.0000 2011-01-07 22.0000 2011-01-09 1.9167 2011-01-10 24.0000 In the "FromTime" column, there are data "gaps" i.e. 2011-01-01 and 2011-01-08 are "missing". So what I'd like to do is to loop through a range of dates (in this instance 2010-12-28 to 2011-01-10) and "fill in" the "missing" data with a duration of 0. As I've just started with LINQ, I feel that it should be "fairly" easy but I can't quite get it right. I'm reading the book "LINQ in Action" but feel that I'm still quite a way off before I can resolve this particular issue. So any help would be much appreciated. David

• Using WCF to expose underlying process

  - by Steven

  I have a server application that spins up and monitors about 8 separate processes that gather data from different systems. The server app then runs some calculations over the aggregated data and stores it in a db. Simple stuff. I now have a requirement to modify the process so that it no longer saves data to the db but rather exposes it directly to clients via WCF. That's cool, I've used WCF a fair bit but I'm struggling a little with it for some reason. Basically my plan is to HOST the WCF service in my application and have calls redirect into the internals of my existing application but I can figure out how to do that without getting the WCF class to encapsulate the existing app. I want the service to inside my current app, not become it. Any suggestions?

• Validating call to web service against schema before sending request

  - by Cen

  I am calling a web service (written in Java) in my web app. I use the WSDL to generate proxy classes using the wsdl.exe command line tool. Everything is working fine. However, I have found out that the web service is not doing any data validation at all when they receive a request from my app. Hence, if I happen to send one minute piece of data that isn't exactly what they want, I receive a general fault error in return, with no specifics at all of what the incorrect (if any) piece of data is. So, before I make the request, I'd like to validate my request against the schema they have provided. Is this possible, and if so, how do I go about this? Thanks in advance

• How can I set the buffer size for the underneath Socket UDP? C#

  - by Jack

  Hi all As we know for UDP receive, we use Socket.ReceiveFrom or UdpClient.receive Socket.ReceiveFrom accept a byte array from you to put the udp data in. UdpClient.receive returns directly a byte array where the data is My question is that How to set the buffer size inside Socket. I think the OS maintains its own buffer for receive UDP data, right? for e.g., if a udp packet is sent to my machine, the OS will put it to a buffer and wait us to Socket.ReceiveFrom or UdpClient.receive, right? How can I change the size of that internal buffer? I have tried Socket.ReceiveBuffSize, it has no effect at all for UDP, and it clearly said that it is for TCP window. Also I have done a lot of experiments which proves Socket.ReceiveBufferSize is NOT for UDP. Can anyone share some insights for UDP internal buffer??? Thanks

• Does the "using" directive provide any benefit?

  - by Adam Drummond

  Is there a programmatic benefit to using a using statement? Notice the difference between this sample: using Application.Data; namespace Application.Web { public class SampleClass { public void SampleMethod() { List<Category> categories = CreateCategoriesData(); Category expected = categories[0]; ... ... } } } And this one: namespace Application.Web { public class SampleClass { public void SampleMethod() { List<Data.Category> categories = CreateCategoriesData(); Data.Category expected = categories[0]; ... ... } } }

• Responding to setters

  - by Simon Cave

  What is the best way to respond to data changes when property setters are called. For example, if I have a property called data, how can I react when [object setData:newData] is called and still use the synthesised setter. Instinctively, I would override the synthesised setter like so: - (void)setData:(DataObject *)newData { // defer to synthesised setter [super setData:newData]; // react to new data ... } ...but of course this doesn't make sense - I can't use super like this. So what is the best way to handle this situation? Should I be using KVO? Or something else?

• HTML input text box vs CakePHP Automagic Form Elements

  - by kwokwai

  Hi all, I was manually creating a simple form with one input text box field like this: <form action="/user/add" method="post"> <input type="text" name="data[user_id]" value="1"> But when I call $this->model->save($this->data) in the Controller, nothing was saved to the Table. Only when I used this and the data in the field was written to the database successfully: $form->create(null, array('url' => '/user/add')); echo $form->input('user_id', array('label' => 'User ID', 'value' => '1'));

• CRC32 calculations for png chunk doesn't match the real one

  - by user2507197

  I'm attempting to mimic the function used for creating CRC's in PNG files, I'm using the autodin II polynomial and the source code from: http://www.opensource.apple.com/source/xnu/xnu-1456.1.26/bsd/libkern/crc32.c My tests have all been for the IHDR chunk, so my parameters have been: crc - 0xffffffff and 0 (both have been suggested) buff - the address of the IHDR Chunk's type. length - the IHDR Chunk's length + 4 (the length of the chunk's data + the length of the type) I printed the calculated CRC in binary, which I compared to the actual CRC of the chunk. I can see no similarities (little-big endian, reversed bits, XOR'd, etc). This is the data for the IHDR chunk (hexadecimal format): length(big endian): d0 00 00 00 (13) type: 49 48 44 52 data: 00 00 01 77 00 00 01 68 08 06 00 00 00 existing CRC: b0 bb 40 ac If anyone can tell me why my calculations are off, or give me a CRC32 function that will work I would greatly appreciate it. Thank-you!

• Django: How do I go about changing my simple app to use Ajax?

  - by swisstony

  I currently have a web page where the user enters some data and then clicks a submit button. I process the data in views.py and then use the same Django template to return and display the original data and the results. What I would like to do is try to give it a bit more of a modern look and feel. You know the sort of thing, the page doesn't refresh but displays a spinning disk until the results are displayed. I assume this means using Ajax? How difficult is it to modify a simple app like this to use Ajax? What is involved? What are the best tools to use? JQuery?

• Dynamic binary from file

  - by Aurel300

  This is a little bit of weird problem here. Say I have a C++ code, running on a specific platform. The only purpose of this code is to run files containing binary, NATIVE to that platform. Now - my question is - HOW would I get the data from these files (could even be by bits, like 1024 bits a cycle) to the memory of machine running my code so that this data would be in the execution part? In other words, can I get the data to somewhere where I can point the instruction pointer? If yes, how? I don't mind if I have to use assembler for this - just so it would work.

• Need help setting up json array

  - by torr

  A database query returns several rows which I loop through as follows: foreach ($query->result() as $row) { $data[$row->post_id]['post_id'] = $row->post_id; $data[$row->post_id]['post_type'] = $row->post_type; $data[$row->post_id]['post_text'] = $row->post_text; } If I json_encode the resulting array ($a['stream']) I get { "stream": { "1029": { "post_id": "1029", "post_type": "1", "post_text": "bla1", }, "1029": { "post_id": "1030", "post_type": "3", "post_text": "bla2", }, "1029": { "post_id": "1031", "post_type": "2", "post_text": "bla3", } } } But the json should actually look like this: { "stream": { "posts": [{ "post_id": "1029", "post_type": "1", "post_text": "bla1", }, { "post_id": "1030", "post_type": "3", "post_text": "bla2", }, { "post_id": "1031", "post_type": "2", "post_text": "bla3", }] } } How should I build my array to get this json right?

• SubProject OR SubFolder ?

  - by user300435

  I am writing an asp.net application that exposes data in 2 ways: 1 - 1 common section that all users can see 2 - a Section that displays data specific to a registered user. in this case the user can decide how it looks (through themes), and manage the data to be displayed. Of course, the logic behind is the same, appearance would be different for as user1 and user2 The questions are : What would be best using : 'http://www.site.com/User1' or 'http://user1.site.com'. knowing that in both cases i have to make the displayed pages look like a seperate site then the root domain in anycase, the pages that will be displayed and customized on the fly are located in a subfolder of the of the asp.net project (projectrootpath\personalpages). What is the best way to map the personalpages subfolder to a subdomain or a 'http://www.site.com/userX' in the address bar. i also use "~/" in the urls which in this case needs to point to the personalpages rather then the root . Any help is gretaly apreciated.

• mapping list of different types implementing same function?

  - by sisif

  I want to apply a function to every element in a list (map) but the elements may have different types but all implement the same function (here "putOut") like an interface. However I cannot create a list of this "interface" type (here "Outputable"). How do I map a list of different types implementing the same function? main :: IO () main = do map putOut lst putStrLn "end" where lst :: [Outputable] -- ERROR: Class "Outputable" used as a type lst = [(Out1 1),(Out2 1 2)] class Outputable a where putOut :: a -> IO () -- user defined: data Out1 = Out1 Int deriving (Show) data Out2 = Out2 Int deriving (Show) instance Outputable Out1 where putOut out1 = putStrLn $ show out1 instance Outputable Out2 where putOut out2 = putStrLn $ show out2 I cannot define it this way: data Out = Out1 Int | Out2 Int Int putOut Out1 = ... putOut Out2 = ... because this is a library and users should be able to extend Out with their own types

• Best way to reduce consecutive NAs to single NA

  - by digEmAll

  I need to reduce the consecutive NA's in a vector to a single NA, without touching the other values. So, for example, given a vector like this: NA NA 8 7 NA NA NA NA NA 3 3 NA -1 4 what I need to get, is the following result: NA 8 7 NA 3 3 NA -1 4 Currently, I'm using the following function: reduceConsecutiveNA2One <- function(vect){ enc <- rle(is.na(vect)) # helper func tmpFun <- function(i){ if(enc$values[i]){ data.frame(L=c(enc$lengths[i]-1, 1), V=c(TRUE,FALSE)) }else{ data.frame(L=enc$lengths[i], V=enc$values[i]) } } Df <- do.call(rbind.data.frame,lapply(1:length(enc$lengths),FUN=tmpFun)) return(vect[rep.int(!Df$V,Df$L)]) } and it seems to work fine, but probably there's a simpler/faster way to accomplish this task. Any suggestions ? Thanks in advance.

• Google checkout - Order processing notification handler

  - by Kunal

  Hi I need to integrate google checkout on my website. I have successfully implemented the order placing and others stuff and using the sandbox I have tested that users can successfully add items to cart and and pay thereafter. I am using my own customized shopping cart written in php mysql. The last thing I need to do is pass the new order id to google checkout and receive notifications with the new order id as well as other data google sends. I know I have to setup a path to the handler script in my accounts. I did it in my sandbox account as well. But can't find a simple pice of code to get it done. Even if I use sample code from google, just cant figure out the format of the returned data in new order notification and also how to send custom data to the cart, which would come back with new order notifications? I am just lost on this. Please help!

• Right design to validate attributes of a class instance

  - by systempuntoout

  Having a simple Python class like this: class Spam(object): __init__(self, description, value): self.description = description self.value = value Which is the correct approach to check these constraints: "description cannot be empty" "value must be greater than zero" Should i: 1.validate data before creating spam object ? 2.check data on __init__ method ? 3.create an is_valid method on Spam class and call it with spam.isValid() ? 4.create an is_valid static method on Spam class and call it with Spam.isValid(description, value) ? 5.check data on setters? 6.... Could you recommend a well designed\Pythonic\not verbose (on class with many attributes)\elegant approach?

I don't know why? Thoughts? AddFileToDB.ashx gets fired, but success never gets run.

• How to make IIS wait for WCF service gets ready?

  - by Kamarey

  I have a WCF service hosted in IIS 7. It takes some minutes until this service finish to load its data and ready for external calls. Data loads in internal thread. The problem is that from IIS point the service is ready just after it was activated (by some call), and it process a request without waiting for data to be loaded. Is it possible to tell IIS that the service is still loading and make this service unavailable for requests? No problem if such request will throw an exception.

• Transfer of directory structure over network

  - by singh

  I am designing a remote CD/DVD burner to address hardware constraints on my machine. My design works like this: (analogous to a network printer) Unix-based machine (acts as server) hosts a burner. Windows-based machine acts as client. Client prepares data to burn and transfers it to the server. Server burns the data on CD/DVD. My question is: what is the best protocol to transfer data over the network (Keeping the same directory hierarchy) between different operating systems?

• PHP/codeigniter - use of exit()

  I have a few pages that require login, so all controllers that link to these pages start with $this->checkSession(); //...rest of the code CheckSession should verify the session is still live, otherwise display a message and stop the execution of the rest of the code in the controller: function checkSession() { if (!$this->session->userdata('is_logged_in')) { //the session has expired! $data['main'] = 'confirmation_message'; $data['title'] = "Session expired"; $this->load->vars($data); $this->load->view('template'); exit(); } } . I was expecting these instructions to happen in sequence, but I only get a blank page. How can I make sure exit() gets executed only after all views are loaded?
