• Photo printing API system?

  - by webdestroya

  I am looking for options to provide customers on my website a way to order prints for photos. (It is a photo sharing site, so it needs to be automated, I don't want any portfolio sites that require uploads and what not). Basically it just needs where I send them the photos, the address, (and possibly billing info) and they make the prints and mail them out. I have searched all over the place for such a system, but none seem to offer what I want. I tried hacking snapfish (which worked, but it says "Return to Picasa" on the buttons, which makes it sort of lame...) Any ideas?

• Form Security (discussion)

  - by Eray Alakese

  I'm asking for brain storming and sharing experience. Which method you are using for form submiting security ? For example , for block automatically sended POST or GET datas, i'm using this method : // Generating random string <?php $hidden = substr(md5(microtime()) ,"-5"); ?> <form action="post.php" .... // assing this random string to a hidden input <input type="hidden" value="<?php echo $hidden;" name="secCode> // and then put this random string to a session variable $_SESSION["secCode"] = $hidden; **post.php** if ($_POST["secCode"] != $_SESSION["secCode"]) { die("You have to send this form, on our web site"); }

• Webkit browsers rendering CSS different than Mozilla Firefox...Why??

  - by JAG2007

  I'm styling a form that was already marked up (made some markup changes), and I normally work in Firefox to style so I can use firebug and the web developer toolbar. On this project, I noticed that my styles are displaying quite differently for one particular area (several elements) in webkit based browsers Chrome and Safari, than in Firefox (we won't even get into Internet Explorer, although it is siding with the Firefox display). I can't figure out though why the styles are displaying so differently. Normally there is some rule that I'm neglecting that Firefox just takes for granted, and the others need it specified. But here I'm not getting why it's displaying this way. In particular I'm referring to the bottom area of the form where users can enter their contact info, then submit the form. I'll attach screen shots for reference as to the discrepancy. Here's the URL so feel free to check it out on your own. Although be advised that this is a production page (already released) so if you try out the form, you WILL BE added to CURE's contact database. http://www.helpcurenow.org/survey2010 Here's the screen shots: Firefox (the way I intend it to look) Chrome, and then Safari - strange change to submit button As a bonus, if anybody wants to help me with figuring out why on earth IE7 wants to not show the background behind the questions only, and how to fix that I would be much obliged! Thanks very much.

• Where can I find a deliberately insecure open source web application?

  - by Phil Laliberte

  As a developer, I've learned that I usually gain a better understanding of best/worst practices through experience. The area of web application security isn't really somewhere where my organization can afford to let developers learn through trial and error. So looking for a hands-on approach to knowledge sharing of best practices in web application security, I was thinking that it would be useful to have an open source application that was deliberately built to be insecure in order to help teach junior developers about application security. Does anyone out there know where to find something like this?

• Do I want an embedded web-server, or what?

  - by mawg

  So, someone want me to hack some code for him. He has a 42" TFT display on which he will display some application/business related data. However, 75% of the screen real estate is unused, so he wants to fill it with "TV/adverts/flash/you know, that kind of thing... web based....". Any advice? Do I want an embedded web-server? If so, which? (he wants free & open source, or as cheap as possible) Do I display it in a browser? (duh! probably, dude) But I don't want/need a menu, address bar, toolbar, etc - it should be full screen (does that mean "kiosk mode"?). Sorry, folks, the requirements are not clear, but I hope that you can guess what he probably means (he is not very techie). How should I proceed with this? Thanks.

• Google Analytics version 3 - How to apply it correctly?

  - by ephramd

  I've added google analytics to my app with the intention of obtaining information about the screens you and send custom events. I am obtained duplicate content ... Also I get different results: "com.package.app.MainScreen" - 300 views and "Main Screen" - 200 views I am interested to get only follow up with the custom name of the activity and not the package. And in any case, because both show different results? public class MainScreen extends Activity { private static final String GA_PROPERTY_ID = "UA-12345678-9"; private static final String SCREEN_LABEL = "Main Screen"; Tracker mTracker; EasyTracker easyTracker; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main_screen); mTracker = GoogleAnalytics.getInstance(this).getTracker(GA_PROPERTY_ID); mTracker.set(Fields.SCREEN_NAME, SCREEN_LABEL); // For Custom Name from activity mTracker.send(MapBuilder.createAppView().build()); easyTracker = EasyTracker.getInstance(this); // Analytics Events ... easyTracker.send(MapBuilder.createEvent("MainScreen", "Play", category.get(1), null).build()); //AnalyticsEvents ... } @Override public void onStart() { super.onStart(); EasyTracker.getInstance(this).activityStart(this); } @Override public void onStop() { super.onStop(); EasyTracker.getInstance(this).activityStop(this); } } And analytics.xml: <?xml version="1.0" encoding="utf-8" ?> <resources xmlns:tools="http://schemas.android.com/tools" tools:ignore="TypographyDashes"> <!--Replace placeholder ID with your tracking ID--> <string name="ga_trackingId">UA-12345678-9</string> <!--Enable automatic activity tracking--> <bool name="ga_autoActivityTracking">true</bool> <!--Enable automatic exception tracking--> <bool name="ga_reportUncaughtExceptions">true</bool> </resources> Google Analytics Dev Guide

• Android - Where to store generated bitmaps?

  - by Josh

  I've got an app which dynamically generates anywhere from 6 to 100 small bitmaps for the user to move around the screen in a given session. I currently generate them in onCreate and store them to the sd card, so that after an orientation change I can grab them out of external storage and display them again. However, this takes time (the loading) and I'd like to keep the bitmap references around between lifecyle changes for quicker access. My question is, is there a better place to store my generated bitmaps? I was thinking about creating a static storage library in my base activity, something that would only need to be reloaded when the app is completely removed from memory (shutdown, other apps need resources, 30 minute restart, etc). Ideally, I'd like the user to be able to back out to the title screen, click a "Resume" button, and in onCreate I just have access to those resident bitmap references instead of having to load them from storage again. For this reason I don't think Activity.onRetainNonConfigurationInstance is what I need. Alternatively, is there a better way to handle multiple generated bitmaps than what I'm doing or the plan I described?

  I have the image position fixed inside div and code is gven below #content{ margin-top:100px; width:900px; color:#009; border:1px solid red; overflow:hidden; display:block; } img { float:left; position:fixed; top:140px; padding:50px; } #text{ display:block; border:1px solid green; width:500px; height:1200px; float:right; overflow:scroll; } #footer{ clear:both; width:600px; height:300px; border:2x solid blue; color:#939; } HTML is <div id="content" > <img src="bar.jpg" width="46" height="639" /> <div id="text"> ggggggggggggggggggfgdfgdfgdgdfgdgdfgdf </div> </div> <div id="footer"> Footer text </div> </body> Now when i scroll down then image comes out of the content div box.

• Creating many polygons with OpenGL is slow?

  - by user146780

  I want to draw many polygons to the screen but i'm quickly noticing that it slows down quickly. As a test I did this: for(int i = 0; i < 50; ++i) { glBegin( GL_POLYGON); glColor3f( 0.0f, 1, 0.0f ); glVertex2f( 500.0 + frameGL.GetCameraX(), 0.0f + frameGL.GetCameraY()); glColor3f( 0.0f, 1.0f, 0.0f ); glVertex2f( 900.0 + frameGL.GetCameraX(), 0.0f + frameGL.GetCameraY()); glColor3f( 0.0f, 0.0f, 0.5 ); glVertex2f(900.0 + frameGL.GetCameraX(), 500.0f + frameGL.GetCameraY() + (150)); glColor3f( 0.0f, 1.0f, 0.0f ); glVertex2f( 500 + frameGL.GetCameraX(), 500.0f + frameGL.GetCameraY()); glColor3f( 1.0f, 1.0f, 0.0f ); glVertex2f( 300 + frameGL.GetCameraX(), 200.0f + frameGL.GetCameraY()); glEnd(); } This is only 50 polygons and already it's gtting slow. I can't upload them directly to the card because my program will allow the user to reshape the verticies. My question is, how can I speed this up. I'm not using depth. I also know it's not my GetCamera() functions because if I create 500,000 polygons spread apart t's fine, it just has trouble showing them in the view. If a graphics card can support 500,000,000 on screen polygons per second, this should be easy right? Thanks

• Implementing Transparent Persistence

  - by Jules

  Transparent persistence allows you to use regular objects instead of a database. The objects are automatically read from and written to disk. Examples of such systems are Gemstone and Rucksack (for common lisp). Simplified version of what they do: if you access foo.bar and bar is not in memory, it gets loaded from disk. If you do foo.bar = baz then the foo object gets updated on disk. Most systems also have some form of transactions, and they may have support for sharing objects across programs and even across a network. My question is what are the different techniques for implementing these kind of systems and what are the trade offs between these implementation approaches?

• Android game logic problem

  - by semajhan

  I'm currently creating a game and have a problem which I think I know why it is occurring but not entirely sure and even if I knew, don't know how to solve. I have a 2D array 10 x 10 and have a "player" class that takes up a tile. Now, I have created 2 instances of the player and move them around via swiping. Around the edges I have put "walls" that the player cannot walk through and everything works fine, until I remove a wall. Once I remove a wall and move the character/player to the edge of the screen, the player cannot go any further. The problem occurs here, where the second instance of the player is not at the edge of the screen but say 2 tiles from the first instance of "player" who is at the edge. If I try moving them further into the direction of the edge, I understand that the first instance of player wouldn't move or do anything but the second instance of player should still move, but it won't. This is the code that executed when the user swipes: if (player.getArrayX() - 1 != player2.getArrayX()) { player.moveLeft(); } else if (player.getArrayX() - 1 == player2.getArrayX() && player.getArrayY() != player2.getArrayY()) { player.moveLeft(); } if (player2.getArrayX() - 1 != player.getArrayX()) { player2.moveLeft(); } else if (player2.getArrayX() - 1 == player.getArrayX() && player2.getArrayY() != player.getArrayY()) { player2.moveLeft(); } In the player class I have: public void moveLeft() { if (alive) { switch (levelMaster.getLevel1(getArrayX() - 1, getArrayY())) { case 0: break; case 1: subX(); // basically moves player left setArrayX(getArrayX() - 1); // shifts x coord of player 1 within tilemap Log.d("semajhan", "x: " + getArrayX()); break; case 9: subX(); setArrayX(getArrayX() - 1); setAlive(false); break; } } } Any help on the matter or further insight would be greatly appreciated, thanks.

• Amazon EC2 multiple servers share session state

  - by Theofanis Pantelides

  Hi everyone, I have a bunch of EC2 servers that are load balanced. Some of the servers are not sharing session, and users keep getting logged in and out. How can I make all the server share the one session, possibly even using a partitionresolver solution public class PartitionResolver : System.Web.IPartitionResolver { private String[] partitions; public void Initialize() { // create the partition connection string table // web1, web2 partitions = new String[] { "192.168.1.1" }; } public String ResolvePartition(Object key) { String oHost = System.Web.HttpContext.Current.Request.Url.Host.ToLower().Trim(); if (oHost.StartsWith("10.0.0") || oHost.Equals("localhost")) return "tcpip=127.0.0.1:42424"; String sid = (String)key; // hash the incoming session ID into // one of the available partitions Int32 partitionID = Math.Abs(sid.GetHashCode()) % partitions.Length; return ("tcpip=" + partitions[partitionID] + ":42424"); } } -theo

• Playing BG Music Across Activities in Android

  - by scarface

  Hello! First time to ask a question here at stackoverflow. Exciting! Haha. We're developing an Android game and we play some background music for our intro (we have an Intro Activity) but we want it to continue playing to the next Activity, and perhaps be able to stop or play the music again from anywhere within the application. What we're doing at the moment is play the bgm using MediaPlayer at our Intro Activity. However, we stop the music as soon as the user leaves that Activity. Do we have to use something like Services for this? Or is MediaPlayer/SoundPool enough? If anyone knows the answer, we'd gladly appreciate your sharing it with us. Thanks!

• How to represent a Many-To-Many relationship in XML or other simple file format?

  - by CSharperWithJava

  I have a list management appliaction that stores its data in a many-to-many relationship database. I.E. A note can be in any number of lists, and a list can have any number of notes. I also can export this data to and XML file and import it in another instance of my app for sharing lists between users. However, this is based on a legacy system where the list to note relationship was one-to-many (ideal for XML). Now a note that is in multiple lists is esentially split into two identical rows in the DB and all relation between them is lost. Question: How can I represent this many-to-many relationship in a simple, standard file format? (Preferably XML to maintain backwards compatibility)

• In a virtual machine monitor such as VMware's ESXi Server, how are shadow page tables implemented?

  - by ali01

  My understanding is that VMMs such as VMware's ESXi Server maintain shadow page tables to map virtual page addresses of guest operating systems directly to machine (hardware) addresses. I've been told that shadow page tables are then used directly by the processor's paging hardware to allow memory access in the VM to execute without translation overhead. I would like to understand a bit more about how the shadow page table mechanism works in a VMM. Is my high level understanding above correct? What kind of data structures are used in the implementation of shadow page tables? What is the flow of control from the guest operating system all the way to the hardware? How are memory access translations made for a guest operating system before its shadow page table is populated? How is page sharing supported? Short of straight up reading the source code of an open source VMM, what resources can I look into to learn more about hardware virtualization?

• Cheapest ways to expose internet services

  - by tmow

  Hi all, we have developed/customized an internet site that provides functionalities like sharing, swap/barter, selling and rent any object/services trough public or private galleries and/or clubs. We'd like now to expose all or some of the services to the public, so that anybody can take advantage of our engine, but without spending too much as we rae running low on budget. At the moment we have developed some RSS interfaces for the public catalogs and is possible to use JQuery to query the engine. Do you have any advices on how to proceed here? We were thinking about something simple like framset, using openID like authentication, or similar technologies. Even if can be the coolest solution, we a would like to avoid the develop soap, rest or xmlrpc APIs as it takes a lot of time ( =money ) Do you have any super smart ideas?

• Most efficient way for testing links

  - by Burnzy

  I'm currently developping an app that is going through all the files on a server and checking every single hrefs to check wether they are valid or not. Using a WebClient or a HttpWebRequest/HttpWebResponse is kinda overkilling the process because it downloads the whole page each time, which is useless, I only need to check if the link do not return 404. What would be the most efficient way? Socket seems to be a good way of doing it, however I'm not quite sure how this works. Thanks for sharing your expertise!

• Converting Source ASCII Files to JPEGs

  - by CommonsWare

  I publish technical books, in print, PDF, and Kindle/MOBI, with EPUB on the way. The Kindle does not support monospace fonts, which are kinda useful for source code listings. The only way to do monospace fonts is to convert the text (Java source, HTML, XML, etc.) into JPEG images. More specifically, due to pagination issues, a given input ASCII file needs to be split into slices of ~6 lines each, with each slice turned into a JPEG, so listings can span a screen. This is a royal pain. My current mechanism to do that involves: Running expand to set a consistent 2-space tab size, which pipes to... a2ps, which pipes to... A small Perl snippet to add a "%%LanguageLevel: 3\n" line, which pipes to... ImageMagick's convert, to take the (E)PS and make a JPEG out it, with an appropriate background, cropped to 575x148+5+28, etc. That used to work 100% of the time. It now works 95% of the time. The rest of the time, I get convert: geometry does not contain image errors, which I cannot seem to get rid of, in part because I don't understand what the problem is. Before this process, I used to use a pretty-print engine (source-highlight) to get HTML out of the source code...but then the only thing I could find to convert the HTML into JPEGs was to automate screen-grabs from an embedded Gecko engine. Reliability stank, which is why I switched to my current mechanism. So, if you were you, and you needed to turn source listings into JPEG images, in an automated fashion, how would you do it? Bonus points if it offers some sort of pretty-print process (e.g., bolded keywords)! Or, if you know what typically causes convert: geometry does not contain image, that might help. My current process is ugly, but if I could get it back to 100% reliability, that'd be just fine for now. Thanks in advance!

• NHibernate: discriminator without common base class?

  - by joniba

  Is it possible to map two classes to the same property without them sharing a common base class? For example, a situation like this: class Rule { public virtual int SequenceNumber { get; set; } public virtual ICondition Condition { get; set; } } interface ICondition { } class ExpressionCondition : ICondition { public virtual string Expression { get; set; } } class ThresholdCondition : ICondition { public virtual int Threshold { get; set; } } I also cannot add some empty abstract class that both conditions inherit from because the two ICondition implementations exist in different domains that are not allowed to reference each other. (Please no responses telling me that this situation should not occur in the first place - I'm aware of it and it doesn't help me.)

• Mouse management in JavaScript games

  - by Jakob

  Im using JavaScript, the HTML5 canvas-element and WebGL to make a simple 3D-game in first person view for fun. Ideally, I would like to control my movement by using the keyboard to move and the mouse to look around, like you usually do in FPS-games. As you probably understand, there are some limits to this in the browser, since the mouse cant be captured: When using the onmousemove event, no further movement will be detected when the mouse pointer reaches the border of my screen (which means that I wont be able to run in a circle for example) Seeing the mouse move across the screen is not the end of the world, but it is a little annoying From what I know, it's impossible to hide the mouse as well as setting it's position in JavaScript. Hence, my question is this: If we cant to those things, what can we do in order to get close to the desktop gaming experience when it comes to the mouse in the browser? And I mean right now, using current APIs. Not "what could be changed in some standard to make life easier". Also, I realize that I could use the keyboard to look around, but then we're back in 1995 when Quake were actually played like that. And of course I know that it would be easier to write a desktop application or use Flash at least, but Im trying to push JavaScript's limits here. Apart from those things, what are your suggestions? Any kind of reference, existing game, crazy idea, hack or even browser specific solution would be appreciated.

• Codeigniter only loads the default controller

  - by fh47331

  I am very new to CodeIgniter, but have been programming PHP for ages. I'm writing some software at the moment and using CI for the first time with it. The default controller is set to the first controller I want to action call 'login' (the controller is login.php, the view is login.php. When the form is submitted it calls the 'authenticate' controller. This executes fine, process the login data correctly and then does a redirect command (without any output to the screen prior) to the next page in this case 'newspage'. The problem is that the redirect, never reaches 'newspage' but the default controller runs again. It doesn't matter what I put ... ht tp://domain.name/anything ... (yes im using .htaccess to remove the index.php) the anything never gets called, just the default controller. I have left the standard 'welcome.php' controller and 'welcome_message.php' in the folders and even putting ht tp://domain.name/welcome all I get is the login screen! (Obviously there shouldn't be a space between the http - thats just done so it does not show as a hyperlink!) Can anyone tell me what i've done wrong!

• How to create a static delegate from main-viewcontroller?

  - by geforce

  Hi, hope someone can help me on learning some new stuff about delegates in iOS-programming. I have a "MainViewController" which is the first VC when the app starts. I´ve a kind of modelselection with different UIImageViews and after choosing one of them, i´m pushing a new VC. I want to handle the modelChoice with a delegate, so all other viewControllers can listen to that and act based on the users choice. But does that mean that i have to alloc a new instance of that "MainViewController" in every VC? Whats the solution on that? How do i create (i think its called) static delegate? Would be great to learn that.. Thanks for sharing..

• What are the general strategies for the server of an FPS multiplayer game to update its clients?

  - by Hooray Im Helping

  A friend and I were having a discussion about how a FPS server updates the clients connected to it. We watched a video of a guy cheating in Battlefield: Bad Company 2 and saw how it highlighted the position of enemies on the screen and it got us thinking. His contention was that the server only updates the client with information that is immediately relevant to the client. I.e. the server won't send information about enemy players if they are too far away from the client or out of the client's line of sight for reasons of efficiency. He was unsure though - he brought up the example of someone hiding behind a rock, not able to see anyone. If the player were suddenly to pop up where he had three players in his line of sight, there would be a 50ms delay before they were rendered on his screen while the server transmitted the necessary information. My contention was the opposite: that the server sends the client all the information about every player and lets the client sort out what is allowed and what isn't. I figured it would actually be less expensive computationally for the server to just send everything to the client and let the client do the heavy lifting, so to speak. I also figured this is how cheat programs work - they intercept the server packets, get the location of enemies, then show them on the client's view. So the question: What are some general policies or strategies a modern first person shooter server employs to keep its clients updated?
