  • Strategy for managing lots of pictures for a website

    - by Nate
    I'm starting a new website that will (hopefully) have a lot of user generated pictures. I'm trying to figure out the best way to store and serve these pictures. The CMS I'm using (umbraco) has a media library that puts a folder on the server for each image. Inside of there you can have different sizes of that same image. That folder has an ID on it and the database has additional information for that image along with the ID of the folder. This works great for small sites, but what if the pictures get up to 10,000, 100,000 or 1,000,000? It seems like the lookup on the directory would take a long time to find the correct folder. I'm on windows 2008 if that makes a difference. I'm not so worried about load. I can load balance my server pretty easily and replicate the images across the servers. The nature of the site won't have a lot of users on it either, but it could have a lot of pics. Thanks. -Nate EDIT After some thought I think I'm going to create a directory for each user under a root image folder then have user's pictures under that. I would be pretty stoked if I had even 5,000 users, so that shouldn't be too bad of a linear lookup. If it does get slow I will break it down into folders like /media/a/adam/image123.png. If it ever gets really big I will expand the above method to build a bigger tree. That would take a LOT of content though.

  • Class Design and Structure Online Web Store

    - by Phorce
    I hope I have asked this in the right forum. Basically, we're designing an Online Store and I am designing the class structure for ordering a product and want some clarification on what I have so far: So a customer comes, selects their product, chooses the quantity and selects 'Purchase' (I am using the Facade Pattern - So subsystems execute when this action is performed). My class structure: < Order > < Product > <Customer > There is no inheritance, more Association < Order has < Product , < Customer has < Order . Does this structure look ok? I've noticed that I don't handle the "Quantity" separately, I was just going to add this into the "Product" class, but, do you think it should be a class of it's own? Hope someone can help.

  • Back to Basics: Structuring a Web Page with CSS and ASP.NET

    Nick Harrison explains why such habits as using nested HTML Tables to position content in the right place on the browser page is bad practice and, nowadays, avoidable. This is just one 'Markup smell' that he discusses on the way to demonstrating the benefits of CSS Style-sheets and ASP.NET Master Pages. span.fullpost {display:none;}

  • TDD - Outside In vs Inside Out

    - by Songo
    What is the difference between building an application Outside In vs building it Inside Out using TDD? These are the books I read about TDD and unit testing: Test Driven Development: By Example Test-Driven Development: A Practical Guide: A Practical Guide Real-World Solutions for Developing High-Quality PHP Frameworks and Applications Test-Driven Development in Microsoft .NET xUnit Test Patterns: Refactoring Test Code The Art of Unit Testing: With Examples in .Net Growing Object-Oriented Software, Guided by Tests---This one was really hard to understand since JAVA isn't my primary language :) Almost all of them explained TDD basics and unit testing in general, but with little mention of the different ways the application can be constructed. Another thing I noticed is that most of these books (if not all) ignore the design phase when writing the application. They focus more on writing the test cases quickly and letting the design emerge by itself. However, I came across a paragraph in xUnit Test Patterns that discussed the ways people approach TDD. There are 2 schools out there Outside In vs Inside Out. Sadly the book doesn't elaborate more on this point. I wish to know what is the main difference between these 2 cases. When should I use each one of them? To a TDD beginner which one is easier to grasp? What is the drawbacks of each method? Is there any materials out there that discuss this topic specifically?

  • Prewritten App for Used Car Dealer?

    - by Shawn Eary
    Is there somewhere I can find a prewritten WebApp (with database) for a used car dealer? The application would need to support the following: Easy setup in a low cost Shared or Cloud Host Give potential customers easy way to browse current inventory (cars on lot) with suggested prices Give dealership easy way to login and update inventory (cars on lot) and suggested prices Give potential customers easy way to send the dealership an inquiry about a specific vehicle on the lot with CAPTCHA style SPAM protection I prefer ASP.NET MVC and Microsoft SQL Server, but I might consider other technologies such as WebForms and LightSwitch (HTML5). I am reasonably comfortable with MVC and WebForms, but I really don't want to waste a bunch of time writing an application that might already exist. I did find a few interesting templates via Bing that seem to control CSS and Layout, but I'm not sure if they contain any business logic or if they would integrate well into an MVC App.

  • How can I screen clients that try to register multiple times?

    - by Aba Dov
    My company offers a bonus to every client that register. We would like to prevent people from abusing this by registering several times. we thought about filtering clients by ip (there is a problem with workplaces where all stations have the same ip) cookies (if cookies are not allowed we might lose a client) I would like your opinions on these two methods and will be glad to hear about new ones. thanks

  • Should I rely on externally-hosted services?

    - by Mattis
    I am wondering over the dangers / difficulties in using external services like Google Chart in my production state website. With external services I mean them that you can't download and host on your own server. (-) Potentially the Google service can be down when my site is up. (+) I don't have to develop those particular systems for new browser technologies, hopefully Google will do that for me. (-) Extra latency while my site fetch the data from the google servers. What else? Is it worth spending time and money to develop my own systems to be more in control of things?

  • What causes "All-in-one USB Card Reader" to create 6 drives that always appear in Disk Management?

    - by tim11g
    I installed a "All-in-one USB Card Reader" to read SD cards and other media. It has caused six new drives to appear in Disk Management with six new drive letter assignments. These drives and letters are always present, even when there are no cards in the reader. When unused, they are labeled "No Media". Why does this multifunction reader cause these phantom Disks to appear and consume drive letters? Every USB port can (and does) allow removable media to be mounted and assigned a drive letter, and the drive letter assignment "disappears" when the USB drive is removed. Why are these card reader's drives and letters staying allocated permanently? Is there anything that can be done to make the slots work like a typical USB drive? (The reader is in fact connected to USB).

    - by The Official Microsoft IIS Site
    How is all started So this week I was working on an extension for WebMatrix , Luke Sampson of http://StudioStyle.es just integrate a cool piece of code from Matt MCElheny .

Still we aspired for an even better experience, currently the WebMatrix user will have to install the ColorThemeEditor...(read more)

  • ASP.NET: Building tree picker dialog using jQuery UI and TreeView control

    - by DigiMortal
    Selecting things from dialogs and data represented as trees are very common things we see in business applications. In this posting I will show you how to use ASP.NET TreeView control and jQuery UI dialog component to build picker dialog that hosts tree data. Source code You can find working example with source code from my examples repository in GitHub. Please feel free to give me feedback about my examples. Source code repository GitHub Building dialog box As I don’t like to invent wheels then I will use jQuery UI to solve the question related to dialogs. If you are not sure how to include jQuery UI to your page then take a look at source code - GitHub also allows you to browse files without downloading them. I add some jQuery based JavaScript to my page head to get dialog and button work. <script type="text/javascript">     $(function () {         $("#dialog-form").dialog({             autoOpen: false,             modal: true         });         $("#pick-node")             .button()             .click(function () {                 $("#dialog-form").dialog("open");                 return false;             });     }); </script> Here is the mark-up of our form’s main content area. <div id="dialog-form" title="Select node">     <asp:TreeView ID="TreeView1" runat="server" ShowLines="True"          ClientIDMode="Static" HoverNodeStyle-CssClass="SelectedNode">         <Nodes>             <asp:TreeNode Text="Root" Value="Root">                 <asp:TreeNode Text="Child1" Value="Child1">                     <asp:TreeNode Text="Child1.1" Value="Child1.1" />                     <asp:TreeNode Text="Child1.2" Value="Child1.2" />                 </asp:TreeNode>                 <asp:TreeNode Text="Child2" Value="Child2">                     <asp:TreeNode Text="Child2.1" Value="Child2.1" />                     <asp:TreeNode Text="Child2.2" Value="Child2.2" />                 </asp:TreeNode>             </asp:TreeNode>         </Nodes>     </asp:TreeView>     &nbsp; </div> <button id="pick-node">Pick user</button> Notice that our mark-up is very compact for what we will achieve. If you are going to use it in some real-world application then this mark-up gets even shorter – I am sure that in most cases the data you display in TreeView comes from database or some domain specific data source. Hacking TreeView TreeView needs some little hacking to make it work as client-side component. Be warned that if you need more than I show you here you need to write a lot of JavaScript code. For more advanced scenarios I suggest you to use some jQuery based tree component. This example works for you if you need something done quickly. Number one problem is getting over the postbacks because in our scenario postbacks only screw up things. Also we need to find a way how to let our client-side code to know that something was selected from TreeView. We solve these to problems at same time: let’s move to JavaScript links. We have to make sure that when user clicks the node then information is sent to some JavaScript function. Also we have to make sure that this function returns something that is not processed by browser. My function is here. <script type="text/javascript">     function         $("#dialog-form").dialog("close");         alert("You selected: " + value + " - " + text);         return undefined;     } </script> Notice that this function returns undefined. You get the better idea why I did so if you look at server-side code that corrects NavigateUrl properties of TreeView nodes. protected override void OnPreRender(EventArgs e) {     base.OnPreRender(e);                 if (IsPostBack)         return;     SetSelectNodeUrls(TreeView1.Nodes); } private void SetSelectNodeUrls(TreeNodeCollection nodes) {     foreach (TreeNode node in nodes)     {         node.NavigateUrl = "javascript:selectNode('" + node.Value +                             "','" + node.Text + "');";         SetSelectNodeUrls(node.ChildNodes);     }        } Now we have TreeView that renders nodes the way that postback doesn’t happen anymore. Instead of postback our callback function is used and provided with selected values. In this function we are free to use node text and value as we like. Result I applied some more bells and whistles and sample data to source code to make my sample more informative. So, here is my final dialog box. Seems very basic but it is not hard to make it look more professional using style sheets. Conclusion jQuery components and ASP.NET controls have both their strong sides and weaknesses. In this posting I showed you how you can quickly produce good results when combining jQuery  and ASP.NET controls without pushing to the limits. We used simple hack to get over the postback issue of TreeView control and we made it work as client-side component that is initialized in server. You can find many other good combinations that make your UI more user-friendly and easier to use.

  • Recommendations for USB flash drive fast at writing small files

    - by Andrew Bainbridge
    I want a drive that I can be used as my work drive, storing a Subversion repo and sandbox for a small project. I'd also like it to be able to store a DVD rip. At the moment I've got a Super Talent pico-C 8gb. It's fast at reading and writing DVD rips, but the performance on small files (ie less than 4k) is utterly terrible (we're talking floppy disk speeds here). This Ars review measured a similar Super Talent drive and pretty much confirmed my measurements (take a look at the random write speeds on page 5). So, I'm looking for a 8gb or bigger drive that doesn't suck at read and write of small files and still has acceptable performance for very large files.

  • Tracking state of a one time event on a big website

    - by Mattis
    Assume a website with 250 million active users. I add a new feature to the website. Once a user visits I want to use a short tutorial to teach them how to use said feature. I only want them to complete the tutorial once (or actively click it away). What is the smart way to code the verification check for this? How do I track the progress in the database? Having a separate table with like NewTutorial_completed = 1 for user_id = 21312315 would just snowball. It also feels intuitively bad to check for every one-time event for every user on every page view. While writing the question I got one idea, to have a separate event log that is checked periodically for any new action the user need to see or perform. I push events to this log and once they are completed they are removed from the log. No need to store NewTutorial_completed = 1-type variables this way. I am sure this is a common problem. I would appreciate any input on what best practice is.

  • Re-Initialize RAID-0 in software after card failure

    - by Ben
    I'm working on a Friend's WD MyBook "1TB" HDD that is not mounting. When I got in to it, I discovered that it is really 2 500GB HDD's set up as RAID-0. It appears that the drives themselves are fine, but that the logic board has failed. My questions is this: can I re-initialize the RAID-0 using software RAID so that I can recover the data to another drive? If so, how and which software RAID would be best (Preferably open source. any platform OK).

  • Website design reviews and advice [closed]

Most of them don't really say what the problem is or how I can manage to redo or make amends to it. Please what do you advice that I do in this case to make it look better. Please feel free to migrate the question to the appropriate SO site, if this question does not belong here. Thank you.

  • Throughput = BS * IOPS?

    - by Marvin
    I've seen in many places that throughput = bs * iops should be true. For example writing at 128k block size to a SAS disk that can support 190 IOPS should give a throughput of ~23 MBps - 23.75(MBs) = 128(BS)*190(SAS-15 IOPS)/1024. Now when I tested it in a VM against a monster NetApp filer I got theses results: # dd if=/dev/zero of=/tmp/dd.out bs=4k count=2097152 8589934592 bytes (8.6 GB) copied, 61.5996 seconds, 139 MB/s To view the IO rate of the VM I used iostat and esxtop, and they both showed around 250 IOPS. So to my understanding the throughput was supposed to be ~1000k: 1000(KBs) = 4(BS)*250(IOPS). dd of 8GB is twice the size of RAM of course, so no page caching here. What am I missing? Thanks!

  • Open Source Bulletin Board with Facebook Group Integration

    - by Brian
    I'm working on a an open-source community-oriented project which needs a highly social component where users can post discussion topics and questions and interact with each other. It would be ideal to facilitate discussion seamlessly between a bulletin board and Facebook. Has anyone seen such an integration? I'm talking about something that goes beyond a simple FB OAuth and actually synchronizes both forum posts / topics / OAuth / comments. Pretty please if a moderator is going to delete this tell me which StackExchange forum is the appropriate place for posting such an inquiry. :)

  • How to access shared folders from file editors?

    - by Marchosius
    I am running a xampp server on one of my other computers, and when using the brows functionality from text editors like gedit, bluefish and Eclipse/Aptana studio I can access the shares I made for the sites running on the server. Even when I right click-edit with-application with the the file browser it does not open the file in the editor. How can get this to work without having to copy the file over from the share then edit and then upload again after I am done? Similar issue when trying to upload a file to hosting server direct from the file server I have with filezilla. with this I also need to copy the file over to my pc and then from there upload to the hosting server with filezilla. EDIT: For eclipse I found a build in functionality to do this. (new-remote system connection-Enter the access details) Nothing yet on FileZilla Hope my Question is clear

  • Semantic Form Markup for Yes or No Questions - Or Should I Tell my Designers to Bugger Off?

    - by sholsinger
    I frequently receive mock-ups of HTML forms with the following prototype: Some long winded yes or no question?   (o) Yes   ( ) No The (o) and ( ) in this prototype represent radio buttons. My personal view is that if the question has only a true or false value then it should be a check box. That said, I have seen this sort of "layout" from almost every designer I've ever worked with. If I were not to question their decision, or question the client's decision, I'd probably mark it up like this: <p class="pseudo_label">Some long winded yes or no question?</p> <input type="radio" name="the_question" id="the_question_yes" value="1"> <label for="the_question_yes" class="after_radio">Yes</label> <input type="radio" name="the_question" id="the_question_no" value="0"> <label for="the_question_no" class="after_radio">No</label> I really don't want to do that. I want to push back and convince them that this should really be a check box and not two radio buttons. But my question is, if I can't convince them – you're welcome to help me try – how should I code that original design requirement such that it is semantic and at least understandable for screen reader users? If I were able to convince my tormentors to change their minds, I would likely code it in the following fashion: <label for="the_question">Some long winded yes or no question?</label> <input type="checkbox" name="the_question" id="the_question" value="1"> What do you think about this issue? Should I push back? Possibly more importantly is either way semantically correct?
