  • Simple rendering produces minor stutter

    - by Ben
    For some reason, this game loop renders the movement of a simple rectangle with no stuttering. double currTime; double prevTime = System.nanoTime() / NANO_TO_SEC; double FPSTIMER = System.nanoTime(); double maxTimeDiff = 100.0 / 1000.0; double delta = 1.0 / 60.0; int processes = 0, frames = 0; while(true){ currTime = System.nanoTime() / NANO_TO_SEC; if(currTime - prevTime > maxTimeDiff) prevTime = currTime; if(currTime >= prevTime){ process(); processes++; prevTime += delta; if(currTime < prevTime){ render(); frames++; } } else{ try{ Thread.sleep((long) (1000 * (prevTime - currTime))); } catch(Exception e){} } if(System.nanoTime() - FPSTIMER > 1000000000.0){ System.out.println("Process: " + (1000 / processes) + "ms FPS: " + (1000 / frames) + "ms"); processes = frames = 0; FPSTIMER += 1000000000.0; } } But for this game loop, I get really minor stuttering where the movement does not look smooth. long prevTime = System.currentTimeMillis(); long prevRenderTime = 0; long currRenderTime = 0; long delta = 0; long msPerTick = 1000 / 60; int frames = 0; int ticks = 0; double FPSTIMER = System.currentTimeMillis(); while (true){ long currTime = System.currentTimeMillis(); delta += (currTime - prevTime) / msPerTick; prevTime = currTime; while (delta >= 1){ ticks++; process(); delta -= 1; } prevRenderTime = System.currentTimeMillis(); render(); frames++; currRenderTime = System.currentTimeMillis(); try{ Thread.sleep((long) ((1000 / FPS) - (currRenderTime - prevRenderTime))); } catch(Exception e){} if(System.currentTimeMillis() - FPSTIMER > 1000.0){ System.out.println("Process: " + (1000.0 / ticks) + "ms FPS: " + (1000.0 / frames) + "ms"); ticks = frames = 0; FPSTIMER += 1000.0; } Is there any critical difference that I'm missing here? The one thing I noticed is that if I uncap the fps for the second game loop, the stuttering goes away. It doesn't make sense to me. Also, the second game loop came from Notch's Minicraft code with just my thread sleeping code added in.

  • Fast determination of whether objects are onscreen in 2D

    - by Ben Ezard
    So currently, I have this in each object's renderer's update method: float a = transform.position.x * Main.scale; float b = transform.position.y * Main.scale; float c = Camera.main.transform.position.x * Main.scale; float d = Camera.main.transform.position.y * Main.scale; onscreen = a + width - c > 0 && a - c < GameView.width && b + height - d > 0 && b - d < GameView.height; transform.position is a 2D vector containing the game engine's definition of where the object is - this is then multiplied by Main.scale to translate that coordinate into actual screen space Similarly, Camera.main.transform.position is the in-engine representation of where the main camera is, and this is also multiplied by Main.scale The problem is, as my game is tile-based, thousands of these updates get called every frame, just to determine whether or not each object should be drawn - how can I improve this please?

  • What do you call the process of converting line breaks into html elements?

    - by Ben Lee
    On sites with user-created content (such as programmers SE) or blogging software back-ends, line breaks entered by the user in the content area are frequently converted into <br> and/or <p> tags when rendered on the front-end. For example, this: A limerick There once was a man from Nantucket Who kept all his cash in a bucket. Might render html like this: <p> A limerick </p> <p> There once was a man from Nantucket<br> Who kept all his cash in a bucket. </p> What is the standard name for this process of converting line breaks into html?

  • Is there any copyleft (GPL-like) license with both the Affero and Lesser modifications?

    - by Ben Voigt
    Looking for a license that covers public network service, like AGPLv3, but like LGPL isn't infectious. Basically I wrote some useful helper functions I want to allow to be used in any work, including closed-source software, but I want to require improvements to MY CODE to be released back to me and the general public. Can you recommend a suitable license? It should also include some of the other AGPL-permitted restrictions (attribution, indemnity), either in the license text or as permitted variations.

  • Port forward based on external IP (for VPS hosting)

    - by Ben Alter
    What I want to do is to host a VPS. First, I'd like to set up a static IP address that forwards to my home IP address (so I can have more than one IP coming into my house). How can I do this without contacting my ISP (and is it even possible?; I don't care about paying for something that does this). Once I have the extra external IP address, how can I forward it to my VPS? How is my router supposed to differentiate between two separate external IP addresses?

  • messed up PATH and can't login

    - by Ben Glasser
    I was screwing around and trying to add some environment variables to my path. I must have made a type or something because once I logged out, I could not lob back in. I know I'm not on caps lock or anything and in fact if I type the wrong password I am informed of this. However, when I type the correct password the desktop starts to load and then loops back to the login prompt. There also no other users on the machine for me to log in as other than guest which does not have the right permissions for me to fix things. Any ideas on where to go from here?

  • How best to take a users signature online? (UK law orientated) [closed]

    - by Ben Griffiths
    Not sure if this is the best place to ask, but I can't seem to find any of the other SE sites that would fit better (unless there's a law one?) I'm building an application that will replace an existing paper based form, and this form would normally be signed by the person filling it in. Looking around, it's hard to find a good definitive resource to explain what I can and cannot accept as far as a signature goes. It looks like some UK government online forms accept just your name typed into a box, but I've also heard you should back up with an email - so that process would be type name into a box along with providing an email address, send out an email, then make them click a link within the email to finally complete the verification. Involving email seems very long winded and leaves the system open to spam filters blocking emails, forgotten emails that just sit in inbox's etc. So, does anyone have any knowledge in this department? Personally, I'd love to just get them to type their name into a box and be done with it!

  • Why are graphics so slow/jerky/lagged with an ATI 4250?

    - by Ben
    Never had a problem with Maverick, always very fast. I upgrade to Natty and the graphics seem to be very lagged. CPU, load, and memory usage is low, all graphics are choppy and lagged though. I have the proprietary driver installed and everything. Alt-Tabbing takes 3-5 seconds for the dialog to popup, zooming in with compiz zoom makes things very slow. I never had any of these problems with 10.10 Thanks

  • no login screen: problem with lightdm or plymouth?

    - by a different ben
    When I boot up my system, I don't get a login screen, just the boot log scrolling by, repeating after a while lines like this: * Starting anac(h)ronistic cron [ OK ] * Stopping anac(h)ronistic cron [ OK ] I can change to another virtual terminal, and start lightdm from there with sudo lightdm restart or sudo start lightdm. Other people with similar problems had just lightdm in their /etc/x11/default-display-manager. I've checked mine and it has /usr/sbin/lightdm in there, so that's not the problem.

  • Windows 7/ 12.04 Dual Boot Mess

    - by Ben
    I am certainly new to ubuntu (linux in general)... I added ubuntu 12.04 as a dual boot to a brand new desktop which had win 7 pre-installed. Both work well Then I tried to change the order of the boot menu to make Ubuntu first and Win7 second... I did this from the windows side (it seems that my setup is relying on windows bootloader, which I don't think I need to change) using the built-in startup manager (I think that's what windows calls it- it's in the control panel). I set Ubuntu as first (default if no user input). then... I ACCIDENTALLY ("hmmm...I wonder what this button does?") set the menu timeout to "0" Now, I cannot change the menu timeout (because I cannot get into windows) and without doing so, I cannot select windows as the OS I would like to boot(I cannot get into windows). Any Ideas?

  • dedicated domain name VS just folders under a single domain?

    - by Ben Keating
    I run WordPress-Multisite for several sites. Each of these sites resolve under a single domain, e.g. example.com/foo/, example.com/bar/. I also have domain names for these e.g. foo.com, bar.com. which are currently redirects, so if a user hits foo.com, they are redirected (301) to example.com/foo/. My question is, should it be the other way around? should I use the dedicated domain names directly? What are the pros/cons of putting multiple sites under a single domain vs their own dedicated domains. I guess im asking with SEO and findability in mind.

  • FTP won't open a connection to client

    - by Ben
    I am running Windows server 2008 on Ubuntu server 12.04.1 via devstack and I am trying to download a file from an ftp server using the windows command line ftp client. When I run the ftp get command I get the following error message: 500 I won't open a connection to 10.0.0.2 (only to XX.XX.XX.XX) 425 No data connection 10.0.0.2 is the internal IP address of the instance, whereas XX.XX.XX.XX is the external address. Is there anyway to make the ftp client use the external address for the data connection, or alternatively have the client establish the connection? Thanks

  • How to connect to the internet via command line or graphical utility given I can't click at the top of the screen?

    - by Ben
    My Ubuntu 12.04 installation has an input problem resulting preventing me from clicking near the top of the screen. That is, there is an unclickable area, circa 60 pixels high and stretching all the way across the screen. I will ask about this in a later question. For now, I would just like to be able to connect to the internet, given this limitation. I am able to access the network connections application by hitting the super key and typing "network connections". There is a LAN and a wireless network available. The network icon in the bar at the top of the screen shows an empty wedge, which I suppose means that wireless is off. I've attached the cable for the Ethernet connection, but it does not seem to have connected automatically. How can I figure out what's going on? (I'll happily edit in the output of any relevant terminal commands.) Thank you.

  • Why does my mic boost automatically go to 100 on every boot?

    - by Ben
    When my computer turns on, it automatically sets the "mic boost" sound setting to 100. This causes a loud static sound in my speakers. I can manually go to alsamixer and turn the mic boost down manually, but I would prefer it if I didn't have to do this every time I turn the computer on. I've tried running sudo alsactl store after fixing the settings, and this does save them, but I have to run sudo alsactl restore to restore the settings. This means that I have to manually fix the sound every time I start the computer anyway, so it isn't really a fix. I tried putting sudo alsactl restore in my startup programs, but that didn't seem to fix anything. I'm running Ubuntu 12.04, but I started having this problem before upgrading from 11.10. I'm using a Sony Vaio laptop. I'm not really sure what made it start; it seemed like I just started having the problem randomly one day. Any help would be appreciated! Edit: here is the output from running amixer: http://paste.ubuntu.com/1060080/

    I have an X79 motherboard and a GTX 670. I have tried to install every combination of Ubuntu 11.10, 12.04, 12.10, Linux Mint 13 and the Nvidia Driver 304.43, 295.xx, etc. I have read everything and pretty much tried everything...drivers from the site, PPAs, some random scripts, editing the xorg.conf file. It has been four days of futile effort. Should I just wait...or something? Has anyone gotten hardware like this to work?

  • Powershell Win32_NetworkAdapterConfiguration Not "seeing" PPP Adapter

    I am trying to get the IP of a PPP VPN network connection, but Win32_NetworkAdapterConfiguration does not seem to "see" it.

  • C# remote web request certificate error

    - by Ben
    Hi. I am currently integrating a payment gateway into an application. Following a successful transaction the remote payment gateway posts details of the transaction back to my application (ITN). It posts to a HttpHandler that is used to read and validate the data. Part of the validation performed is a POST made by the handler to a validation service provided by the payment gateway. This effectively posts some of the original form values received back to the payment gateway to ensure they are valid. The url that I am posting back to is: "https://sandbox.payfast.co.za/eng/query/validate" and the code I am using: /// <summary> /// Posts the data back to the payment processor to validate the data received /// </summary> public static bool ValidateITNRequestData(NameValueCollection formVariables) { bool isValid = true; try { using (WebClient client = new WebClient()) { string validateUrl = (UseSandBox) ? SandboxValidateUrl : LiveValidateUrl; byte[] responseArray = client.UploadValues(validateUrl, "POST", formVariables); // get the resposne and replace the line breaks with spaces string result = Encoding.ASCII.GetString(responseArray); result = result.Replace("\r\n", " ").Replace("\r", "").Replace("\n", " "); if (result == null || !result.StartsWith("VALID")) { isValid = false; LogManager.InsertLog(LogTypeEnum.OrderError, "PayFast ITN validation failed", "The validation response was not valid."); } } } catch (Exception ex) { LogManager.InsertLog(LogTypeEnum.Unknown, "Unable to validate ITN data. Unknown exception", ex); isValid = false; } return isValid; } However, on calling WebClient.UploadValues the following exception is raised: System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure. at System.Net.Security.SslState.StartSendAuthResetSignal(ProtocolToken message, AsyncProtocolRequest asyncRequest, Exception exception) at For the sake of brevity I haven't listed the full call stack (I can do if anyone thinks it will help). The remote certificate does appear to be valid. To get around the problem I did try adding a new RemoteCertificateValidationCallback that always returned true but just ended up getting the following exception: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) at System.Security.CodeAccessPermission.Demand() at System.Net.ServicePointManager.set_ServerCertificateValidationCallback(RemoteCertificateValidationCallback value) at NopSolutions.NopCommerce.Payment.Methods.PayFast.PayFastPaymentProcessor.ValidateITNRequestData(NameValueCollection formVariables) The action that failed was: Demand The type of the first permission that failed was: System.Security.Permissions.SecurityPermission The Zone of the assembly that failed was: MyComputer So I am not sure this will work in medium trust? Any help would be much appreciated. Thanks Ben

  • Nested Sortable JQuery list doesn't work in IE while it does in FF

    - by Ben Fransen
    Hello everybody, While I'm using this site quite often as a resource for jQuery related problems I can't seem to find an answer this time. So here is my first post. During daytime at work I'm developing an informationsystem for generating MS Word documents. One of the modules I'm developing is for defining a default chapterselection for the table of contents and selecting texts by the given chapters. A user can submit new chapters and if necessary, add them as childchapter to a parent, flag them as 'adopt in TOC' and link a default text (from another module) to the chapter. My chapterlist is retreived recursively from a MySQL table and could look something like this: <ul class="sortableChapterlist"> <li>1</li> <li>2 <ul class="sortableChapterlist"> <li>2.1</li> <li>2.2</li> <li>2.3 <ul class="sortableChapterlist"> <li>2.3.1</li> <li>2.3.2</li> </ul> </li> </ul> </li> </ul> In FireFox the code works like a charm but IE (7) doesn't seem to like it that much. I'm only able to correctly drag arround the mainchapters. When attempting to drag a subchapter, no matter it's level, the correspondending mainchapter lifts up with some child, never all. This is the jQuery code I'm using to accomplish the task: $(function(){ $(".sortableChapterlist").sortable({ opacity: 0.7, helper: 'clone', cursor: 'move' }); $(".sortableChapterlist").selectable(); $(".sortableChapterlist").disableSelection(); }); Does anybody have some ideas about this? I'm guessing IE kinda falls over the multiple class reference "chapter_list" in combination with jQuery trying to handle the draggable/sortable. Kinds regards from Holland, Ben Fransen

  • please explain NHibernate HiLo

    - by Ben
    I'm struggling to get my head round how the HiLo generator works in NHibernate. I've read the explanation here which made things a little clearer. My understanding is that each SessionFactory retrieves the high value from the database. This improves performance because we have access to IDs without hitting the database. The explanation from the above link also states: For instance, supposing you have a "high" sequence with a current value of 35, and the "low" number is in the range 0-1023. Then the client can increment the sequence to 36 (for other clients to be able to generate keys while it's using 35) and know that keys 35/0, 35/1, 35/2, 35/3... 35/1023 are all available. How does this work in a web application as don't I only have one SessionFactory and therefore one hi value. Does this mean that in a disconnected application you can end up with duplicate (low) ids in your entity table? In my tests I used these settings: <id name="Id" unsaved-value="0"> <generator class="hilo"/> </id> I ran a test to save 100 objects. The IDs in my table went from 32768 - 32868. The next hi value was incremented to 2. Then I ran my test again and the Ids were in the range 65536 - 65636. First off, why start at 32768 and not 1, and secondly why the jump from 32868 to 65536? Now I know that my surrogate keys shouldn't have any meaning but we do use them in our application. Why can't I just have them increment nicely like a SQL Server identity field would. Finally can someone give me an explanation of how the max_lo parameter works? Is this the maximum number of low values (entity ids in my head) that can be created against the high value? This is one topic in NHibernate that I have struggled to find documentation for. I read the entire NHibernate in action book and it still doesn't go into how this works in any detail. Thanks Ben

  • Android - Transforming widgets within transformed widgets and the resulting usability issues.

    - by Ben Rose
    Hello. I'm new to Android application development and I'm currently experimenting with various UI ideas. In the image below, you can see a vertically scrolling list of horizontally scrolling galleries (and also textviews as you can see). I'm also doing some matrix and camera transformations which I will come to in a minute. For the background of the list elements, I use green. Blue is the background of the galleries, and red is the background for the images. These are just for my benefit of learning. The galleries being used are extended classes where I overrode the drawChild method to perform a canvas scale operation in order for the image closest to the center (width) to be larger than the others. The list view going vertically, I overrode the drawChild method and used the camera rotations from lack of depth dimension in the canvas functionality. The items in the list are scaled down and rotated relative to their position's proximity to the center (height). I understood that scrolling and clicking would not necessarily follow along with the image transforms, but it appears as though the parent Gallery class's drawing is constrained to the original coordinates as well (see photo below). I would love to hear any insight any of you have regarding how I can change the coordinates of the galleries in what is rendered via gallery scroll and the touch responsiveness of said gallery. Images in the gallery are not same dimensions, so don't let that throw you in looking at the image below Thanks in advance! Ben link to image (could not embed) -- Update: I was using my test application UI and noticed that when I got the UI to the point of the linked image and then I touched the top portion of the next row in the list, the gallery updated to display the proper representation. So, I added a call to clearFocus() in the drawChild method and that resulted in more accurate drawing. It does seem a tad slower, and since I'm on the Incredible, I'm worried it is a bloated solution. In any event, I would still appreciate any thoughts you have regarding the best way to have the views display properly and how to translate the touch events in the gallery's new displayed area to its touchable coordinates so that scrolling on the actual images works when the gallery has moved. Thanks!

  • UIScrollView Infinite Scrolling

    - by Ben Robinson
    I'm attempting to setup a scrollview with infinite (horizontal) scrolling. Scrolling forward is easy - I have implemented scrollViewDidScroll, and when the contentOffset gets near the end I make the scrollview contentsize bigger and add more data into the space (i'll have to deal with the crippling effect this will have later!) My problem is scrolling back - the plan is to see when I get near the beginning of the scroll view, then when I do make the contentsize bigger, move the existing content along, add the new data to the beginning and then - importantly adjust the contentOffset so the data under the view port stays the same. This works perfectly if I scroll slowly (or enable paging) but if I go fast (not even very fast!) it goes mad! Heres the code: - (void) scrollViewDidScroll:(UIScrollView *)scrollView { float pageNumber = scrollView.contentOffset.x / 320; float pageCount = scrollView.contentSize.width / 320; if (pageNumber > pageCount-4) { //Add 10 new pages to end mainScrollView.contentSize = CGSizeMake(mainScrollView.contentSize.width + 3200, mainScrollView.contentSize.height); //add new data here at (320*pageCount, 0); } //*** the problem is here - I use updatingScrollingContent to make sure its only called once (for accurate testing!) if (pageNumber < 4 && !updatingScrollingContent) { updatingScrollingContent = YES; mainScrollView.contentSize = CGSizeMake(mainScrollView.contentSize.width + 3200, mainScrollView.contentSize.height); mainScrollView.contentOffset = CGPointMake(mainScrollView.contentOffset.x + 3200, 0); for (UIView *view in [mainContainerView subviews]) { view.frame = CGRectMake(view.frame.origin.x+3200, view.frame.origin.y, view.frame.size.width, view.frame.size.height); } //add new data here at (0, 0); } //** MY CHECK! NSLog(@"%f", mainScrollView.contentOffset.x); } As the scrolling happens the log reads: 1286.500000 1285.500000 1284.500000 1283.500000 1282.500000 1281.500000 1280.500000 Then, when pageNumber<4 (we're getting near the beginning): 4479.500000 4479.500000 Great! - but the numbers should continue to go down in the 4,000s but the next log entries read: 1278.000000 1277.000000 1276.500000 1275.500000 etc.... Continiuing from where it left off! Just for the record, if scrolled slowly the log reads: 1294.500000 1290.000000 1284.500000 1280.500000 4476.000000 4476.000000 4473.000000 4470.000000 4467.500000 4464.000000 4460.500000 4457.500000 etc.... Any ideas???? Thanks Ben.

  • backbone.js Model.get() returns undefined, scope using coffeescript + coffee toaster?

    - by benipsen
    I'm writing an app using coffeescript with coffee toaster (an awesome NPM module for stitching) that builds my app.js file. Lots of my application classes and templates require info about the current user so I have an instance of class User (extends Backbone.Model) stored as a property of my main Application class (extends Backbone.Router). As part of the initialization routine I grab the user from the server (which takes care of authentication, roles, account switching etc.). Here's that coffeescript: @user = new models.User @user.fetch() console.log(@user) console.log(@user.get('email')) The first logging statement outputs the correct Backbone.Model attributes object in the console just as it should: User _changing: false _escapedAttributes: Object _pending: Object _previousAttributes: Object _silent: Object attributes: Object account: Object created_on: "1983-12-13 00:00:00" email: "[email protected]" icon: "0" id: "1" last_login: "2012-06-07 02:31:38" name: "Ben Ipsen" roles: Object __proto__: Object changed: Object cid: "c0" id: "1" __proto__: ctor app.js:228 However, the second returns undefined despite the model attributes clearly being there in the console when logged. And just to make things even more interesting, typing "window.app.user.get('email')" into the console manually returns the expected value of "[email protected]"... ? Just for reference, here's how the initialize method compiles into my app.js file: Application.prototype.initialize = function() { var isMobile; isMobile = navigator.userAgent.match(/(iPhone|iPod|iPad|Android|BlackBerry)/); this.helpers = new views.DOMHelpers().initialize().setup_viewport(isMobile); this.user = new models.User(); this.user.fetch(); console.log(this.user); console.log(this.user.get('email')); return this; }; I initialize the Application controller in my static HTML like so: jQuery(document).ready(function(){ window.app = new controllers.Application(); }); Suggestions please and thank you!

  • Saving child collections with NHibernate

    - by Ben
    Hi, I am in the process or learning NHibernate so bare with me. I have an Order class and a Transaction class. Order has a one to many association with transaction. The transaction table in my database has a not null constraint on the OrderId foreign key. Order class: public class Order { public virtual Guid Id { get; set; } public virtual DateTime CreatedOn { get; set; } public virtual decimal Total { get; set; } public virtual ICollection<Transaction> Transactions { get; set; } public Order() { Transactions = new HashSet<Transaction>(); } } Order Mapping: <class name="Order" table="Orders"> <cache usage="read-write"/> <id name="Id"> <generator class="guid"/> </id> <property name="CreatedOn" type="datetime"/> <property name="Total" type="decimal"/> <set name="Transactions" table="Transactions" lazy="false" inverse="true"> <key column="OrderId"/> <one-to-many class="Transaction"/> </set> Transaction Class: public class Transaction { public virtual Guid Id { get; set; } public virtual DateTime ExecutedOn { get; set; } public virtual bool Success { get; set; } public virtual Order Order { get; set; } } Transaction Mapping: <class name="Transaction" table="Transactions"> <cache usage="read-write"/> <id name="Id" column="Id" type="Guid"> <generator class="guid"/> </id> <property name="ExecutedOn" type="datetime"/> <property name="Success" type="bool"/> <many-to-one name="Order" class="Order" column="OrderId" not-null="true"/> Really I don't want a bidirectional association. There is no need for my transaction objects to reference their order object directly (I just need to access the transactions of an order). However, I had to add this so that Order.Transactions is persisted to the database: Repository: public void Update(Order entity) { using (ISession session = NHibernateHelper.OpenSession()) { using (ITransaction transaction = session.BeginTransaction()) { session.Update(entity); foreach (var tx in entity.Transactions) { tx.Order = entity; session.SaveOrUpdate(tx); } transaction.Commit(); } } } My problem is that this will then issue an update for every transaction on the order collection (regardless of whether it has changed or not). What I was trying to get around was having to explicitly save the transaction before saving the order and instead just add the transactions to the order and then save the order: public void Can_add_transaction_to_existing_order() { var orderRepo = new OrderRepository(); var order = orderRepo.GetById(new Guid("aa3b5d04-c5c8-4ad9-9b3e-9ce73e488a9f")); Transaction tx = new Transaction(); tx.ExecutedOn = DateTime.Now; tx.Success = true; order.Transactions.Add(tx); orderRepo.Update(order); } Although I have found quite a few articles covering the set up of a one-to-many association, most of these discuss retrieving of data and not persisting back. Many thanks, Ben

  • I'm looking for this graph solution

    - by Ben Fransen
    Hello all, Recently I found a pretty graph when I was browsing the adminskins at ThemeForest and in one of the templates I found a really nice, smooth, clean graph. But I've searching arround but so far without luck finding out which solution is used. And example can be found at: http://enstyled.com/adminus/original/page.html The source of this graph looks like: <table class="stats bar" cellpadding="0" cellspacing="0" width="100%"> <thead> <tr> <td>&nbsp;</td> <th scope="col">02.09</th> <th scope="col">03.09</th> <th scope="col">04.09</th> <th scope="col">05.09</th> <th scope="col">06.09</th> <th scope="col">07.09</th> <th scope="col">08.09</th> <th scope="col">09.09</th> <th scope="col">10.09</th> <th scope="col">11.09</th> <th scope="col">12.09</th> <th scope="col">01.10</th> <th scope="col">02.10</th> <th scope="col">03.10</th> </tr> </thead> <tbody> <tr> <th scope="row">Page views</th> <td>1800</td> <td>900</td> <td>700</td> <td>1200</td> <td>600</td> <td>2800</td> <td>3200</td> <td>500</td> <td>2200</td> <td>1000</td> <td>1200</td> <td>700</td> <td>650</td> <td>800</td> </tr> <tr> <th scope="row">Unique visitors</th> <td>1600</td> <td>650</td> <td>550</td> <td>900</td> <td>500</td> <td>2300</td> <td>2700</td> <td>350</td> <td>1700</td> <td>600</td> <td>1000</td> <td>500</td> <td>400</td> <td>700</td> </tr> </tbody> </table> Can someone please tell me which graphingsolution is used here? Thanks in advance, Ben Fransen
