  • What would a start-to-finish development procedure would look like?

    - by Tom Busby
    I have a problem that my developer friends share. We recently left university and find ourselves either end up working for a firm which already has good procedures (TDD, automated testing, proper agile development, etc) or working for a firm which doesn't. I want to learn some of these vital skills and get a grip on what a complete start-to-finish development procedure would look like. What differences would be between a smaller project, and a long term project with many team members.

  • How to Export Multiple Contacts in Outlook 2013 to Multiple vCards or a Single vCard

    - by Lori Kaufman
    We’ve shown you how to export a contact to and import a contact from a vCard (.vcf) file. However, what if you want to export multiple contacts at the same time to multiple vCard files or even a single vCard file? Outlook doesn’t allow you to directly export all your contacts as vCard files or as a single vCard file, but there is a way to accomplish both tasks. Export Multiple Contacts to Multiple vCard Files Outlook allows you to forward contact information as a vCard. You can also select multiple contacts and forward them all at once. This feature allows you to indirectly export multiple contacts at once to multiple vCard files. Click the People tab to access your contacts. Select all the contacts you want to export using the Shift and Ctrl keys as needed. Select Contacts the same way you would select files in Windows Explorer. Click Forward Contact in the Share section on the Home tab and select As a Business Card from the drop-down menu. The selected contacts attached to a new email message as .vcf files. To select all the attached .vcf files, right-click in the Attached box and select Select All from the popup menu. Make sure the folder to which you want to export the contacts is open in Windows Explorer. Drag the selected attached .vcf files from the new email message to the open folder in Windows Explorer. A .vcf file is created for each contact you selected and dragged to the folder. You can close the Message window by clicking on the X in the upper, right corner of the window. NOTE: You can also close the Message window by clicking the File tab. Then, click the Close option on the left. Because you already have your .vcf files, you don’t need to save or send the message, so click No when asked if you want to save your changes. If it turns out that a draft of your message was saved, the following message displays. Click No to delete the draft. Export Multiple Contacts to a Single vCard (.vcf) File If you would rather export your contacts to a single vCard (.vcf) File, there is a way to do this using Gmail. We’ll export the contacts from Outlook as a .csv file and then use Gmail to convert the .csv file to a .vcf file. Select the contacts you want to export on the People page and click the File tab. On the Account Information screen, click Open & Export in the list on the left. On the Open screen, click Import/Export. The Import and Export Wizard displays. Select Export to a file from the Choose an action to perform list and click Next. In the Create a file of type box, select Comma Separated Values. Click Next. Contacts should be already selected in the Select folder to export from box. If not, select it. Click Next. Click Browse to the right of the Save exported file as box. Navigate to the folder to which you want to export the .csv file. Enter a name for the file in the File name edit box, keeping the .csv extension. The path you selected is entered into the Save exported file as edit box. Click Next. The final screen of the Export to a File dialog box displays listing the action to be performed. Click Finish to begin the export process. Once the export process is finished, you will see the .csv file in the folder in Windows Explorer. Now, we will import the .csv file into Gmail. Go to Gmail and sign in to your account. Click Gmal in the upper, left corner of the main page and select Contacts from the drop-down menu. On the Contacts page, click More above your list of contacts and select Import from the drop-down menu. Click Browse on the Import contacts dialog box that displays. Navigate to the folder in which you saved the .csv file and select the file. Click Open. Click Import on the Import contacts dialog box. A screen displays listing the contacts you imported, but not yet merged into your main Gmail contacts list. Select the contacts you imported. NOTE: The contacts you imported may be the only contacts in this list. If that’s the case, they all should be automatically selected. Click More and select Export from the drop-down menu. On the Export contacts dialog box, select Selected contacts to indicate which contacts you want to export. NOTE: We could have selected The group Imported 10/10/13 because that contains the same two contacts as the Selected contacts. Select vCard format for the export format. Click Export. Gmail creates a contacts.vcf file containing the selected contacts and asks you whether you want to open the file with Outlook or save the file. To save the file, select the Save File option and click OK. Navigate to the folder in which you want to save the contacts.vcf file, change the name of the file in the File name edit box, if desired, and click Save. The .vcf file is saved to the selected directory and contains all the contacts you exported from Outlook. This could be used as a way to backup your contacts in one file. You could also backup the .csv file. However, if you have a lot of contacts you will probably find that the .vcf file is smaller. We only exported two contacts, and our .csv file was 2 KB, while the .vcf file was 1 KB. We will be showing you how to import multiple contacts from a single .vcf file into Outlook soon.

  • FTP Publishing with the new Windows Azure Release

    - by Harish Ranganathan
    There is a good chance you might have stumbled upon the new Windows Azure Release that we made on June 6th.  Scott Guthrie’s Post quite summarizes the overall new features. One of my favorite features is the Windows Azure Websites and the ability to do publish files to Azure using your FTP Client. Windows Azure Websites offers low cost (free upto 10 websites) web hosting where you can deploy any website that can run on IIS 7.0, quickly. The earlier releases of Azure SDKs and the Azure platform support .NET 3.5 & above for running your applications.  This was a constraint for many since there are/were a lot of ASP.NET 2.0 applications built over time and simply to put it on Azure, many of you were skeptical to migrate it to .NET 4. Windows Azure Websites offer the flexibility of running IIS 7.0 supported .NET Versions which means you can run .NET 1.1, 2.0, 3.5 and .NET 4.  Not just that! You can also run classic ASP Applications. Windows Azure Websites don’t need you to go through the complexity of adding the Cloud Project Template and then publishing the Configuration Files.  Lets take a step by step understanding of Websites and publishing using FTP. I downloaded the Club Website Starter Kit from http://www.asp.net/downloads/starter-kits/club It also requires a database and I downloaded the SQL Scripts and created a SQL Server Database called Club. This installs a Web Site Project Template.  Note that I am running Windows 8 Release Preview and Visual Studio 2012 RC.  After installing the template, select File – New – Website and don’t forget to choose the Framework version as .NET 2.0 You can see the “Club Website Starter Kit” .  Once you select the Website gets created.  You would encounter a warning indicating that the Club Website Starter Kit uses SQL Express and the recommended database is LocalDB Express.  Click ok to continue.  Once the Website is created open up the Web.config and locate the “ClubSiteDB” connection string.  By default, it points to a SQL Express Database.  Instead configure it to use your local SQL Server. Also, open up Global.asax and comment out the following line if (!Roles.RoleExists("Administrators")) Roles.CreateRole("Administrators"); There seems to be an issue in the code that doesn’t create the role.  Post that, hit CTRL+F5 and you should be able to see the Website Running, as below So, now we have the Club Starter Kit site up running locally.  Moving to Azure Visit http://manage.windowsazure.com/ and sign up for a trial account.  This allows you to host up to 10 websites for free and a host of other benefits.  The free Websites can be extended to an year without any charge.  Once you have signed up, sign in to the portal using the Live ID used for sign up. After signing in, you would be presented with the “All Items” listing page which lists, Websites, Cloud Services, Databases etc.,  If this is the first time, you wouldn’t find anything. Click on the “Websites” link from the left menu.  Click on “New” in the bottom and it should show up a dialog.  In the same, select Website and click on “Quick Create” and in the URL Textbox, specify “MyFirstDemo” and click the “Create Web Site” link below. It should take a few seconds to create the Website.  Once the Website is created, click on the listing and it should open up the Dashboard.  Since we haven’t done anything yet, there shouldn’t be any statistics Click on the “Download publish profile” link in the right bottom.  This file has the FTP publishing settings. Also, if you scroll down you can see the FTP URL for this site.  It should typically start ftp://waws-xxxx-xxx-xxxx In the downloaded publish profile file, you can also find the ftp URL.  Pick the following from this file publishUrl (the 2nd one, the one that features after publishMethod =”FTP”) and the userName and userPWD that follows. Note that we have everything required to publish the files.  But since the Club Starter Kit uses Databases, we need to have the Database running on SQL Azure.  Go back to the Main Menu and click on “New” in the bottom but this time select “SQL Database” and provide “Club” as Database name for “Quick Create” If this is the first time a Server would be created.  Otherwise, it would pickup the existing server name. Once the database is created, you can use the SQL Azure Migration Wizard http://sqlazuremw.codeplex.com/ and provide the credentials to connect to local database and then the SQL Azure database for migrating the “Club” database.  The migration wizard UI hasn’t changed much and is the same as explained by me in one my posts earlier http://geekswithblogs.net/ranganh/archive/2009/09/29/taking-your-northwind-database-to-sql-azure-and-binding-it.aspx Once the database is migrated, come back to the main screen and click on the Database base in the Azure Management Portal.  It opens up the dashboard of the database.  Click on “Show connection Strings” and it would popup a list of connection string formats.  Choose the ADO.NET connection string and after editing the password with the password that you provided when creating the database server in the Azure Portal, paste it into the config file of the Club Starter Kit Website.  Just to reiterate, the connection string key is ClubSiteDB. Try running the Website once to ensure that the application though running locally could connect to the SQL Database running on Azure. Once you are able to run the website successfully, we are all set to do the FTP Publishing. Download your favorite FTP tool.  I use http://filezilla-project.org/ In the Host Textbox, paste the FTP URL that you picked up from the publish profile file and also paste the username and password.  Click on “QuickConnect”.  If everything is fine, you should be able to connect to the remote server.  If it is successfully connected, you can see the wwwroot folder of the Website, running in Azure Make sure on the “Local Site” in the left, you choose the path to the folder of your Website.  Open up the Website folder on the left such that it lists all the files and folders inside.  Select all of them and click select “Upload” or simply drag and drop all the files to the root folder that is listed above.  Once the publishing is done, you should be able to hit the SiteURL that you can find the dashboard page of the website.  In our case, it would be http://MyFirstDemo.azurewebsites.net That’s it, we have now done FTP publishing in Azure and that too we are running a .NET 2.0 Website on Azure. Cheers !!!

Then on Tuesday and Wednesday, the Forrester Customer Experience Forum East also kicks off in New York City where they'll examine how businesses can "reap the full business benefits of the customer experience revolution." So, are we in the midst of a customer experience revolution? As a consumer, I can answer that question with a definitive “yes.” When I bought my very first car, I had a lot of questions. How do I know if I’m paying a fair price? How do I know if this dealer is honest? Why do I have to sit through these good cop, bad cop shenanigans between sales and sales management at the dealership? Why do I feel like I’m doing these people a favor by giving them my business? In the end the whole experience left me feeling deeply unsatisfied. I didn’t feel that I held all that much power over the experience and the only real negotiating trick I had was to walk out, which I did, many times before actually making a purchase. Fast forward to a year ago and I found myself back in the market for a new car. The very first car that I bought had finally kicked the bucket after many years, many repair bills, and much wear and tear. Man, I had loved that car. It was time to move on, but I had a knot in my stomach when I reflected back on my last car purchase experience and dreaded the thought of going through that again. Could that have been the reason why I drove my old car for so long? But as I started the process of researching new cars, I started to feel really confident. I had a wealth of online information that helped me in my search. I went to Edmunds and plugged in some information on my preferences and left with a short list of vehicles. After an afternoon spent test driving the cars my short list, I had determined my favorite – it was a model I didn’t even know about until my research on Edmunds! But I didn’t want to go back to the dealership where I test drove it. They were clearly old school and wanted me to buy the way that they wanted to sell. No thanks! After that I went back online. I figured out exactly what people had paid for this car in my area. I found out what kind of discount others were able to negotiate from an online community forum dedicated to the make and model. I found out how the sales people were being incentivized by the manufacturer that month. I learned which dealers had the best ratings and reviews. This was actually getting exciting. I was feeling really empowered. My next step was to request online quotes from the some of the highest rated dealers but I already knew exactly how much I was going to pay. This was really a test for the dealers. My new mantra was “let he who delivers the best customer experience win.” An inside sales rep from one dealer responded to my quote request within a couple of hours. I told him I had already decided on the make and model and it was just a matter of figuring out who I would buy it from. I also told them that I was really busy and wouldn’t set foot in the dealership unless we had come to terms beforehand. Lastly, I let him know that I’d prefer to work out the details via email. He promised to get back to me shortly with a detailed quote. Over the next few days I received calls from other dealers. One asked me a host of questions that I had already answered in their lengthy online form. Another blamed their website performance issues for their delay in responding to my request. But by then it didn’t really matter because I’d already bought the car days before from the dealer who responded to me first and who was willing to adjust their sales process to accommodate my buying one. So, yes, I really do believe we are in the midst of a customer experience revolution. And every revolution leaves some victorious and other vanquished. Which side do you want to be on when it comes to the customer experience revolution?

  • Using JQuery tabs in an HTML 5 page

    - by nikolaosk
    In this post I will show you how to create a simple tabbed interface using JQuery,HTML 5 and CSS.Make sure you have downloaded the latest version of JQuery (minified version) from http://jquery.com/download.Please find here all my posts regarding JQuery.Also have a look at my posts regarding HTML 5.In order to be absolutely clear this is not (and could not be) a detailed tutorial on HTML 5. There are other great resources for that.Navigate to the excellent interactive tutorials of W3School.Another excellent resource is HTML 5 Doctor.Two very nice sites that show you what features and specifications are implemented by various browsers and their versions are http://caniuse.com/ and http://html5test.com/. At this times Chrome seems to support most of HTML 5 specifications.Another excellent way to find out if the browser supports HTML 5 and CSS 3 features is to use the Javascript lightweight library Modernizr.In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like.You can use Visual Studio 2012 Express edition. You can download it here. Let me move on to the actual example.This is the sample HTML 5 page<!DOCTYPE html><html lang="en">  <head>    <title>Liverpool Legends</title>    <meta http-equiv="Content-Type" content="text/html;charset=utf-8" >    <link rel="stylesheet" type="text/css" href="style.css">    <script type="text/javascript" src="jquery-1.8.2.min.js"> </script>     <script type="text/javascript" src="tabs.js"></script>       </head>  <body>    <header>        <h1>Liverpool Legends</h1>    </header>     <section id="tabs">        <ul>            <li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=9143136#first-tab">Defenders</a></li>            <li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=9143136#second-tab">Midfielders</a></li>            <li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=9143136#third-tab">Strikers</a></li>        </ul>   <div id="first-tab">     <h3>Liverpool Defenders</h3>     <p> The best defenders that played for Liverpool are Jamie Carragher, Sami Hyypia , Ron Yeats and Alan Hansen.</p>   </div>   <div id="second-tab">     <h3>Liverpool Midfielders</h3>     <p> The best midfielders that played for Liverpool are Kenny Dalglish, John Barnes,Ian Callaghan,Steven Gerrard and Jan Molby.        </p>   </div>   <div id="third-tab">     <h3>Liverpool Strikers</h3>     <p>The best strikers that played for Liverpool are Ian Rush,Roger Hunt,Robbie Fowler and Fernando Torres.<br/>      </p>   </div> </div></section>            <footer>        <p>All Rights Reserved</p>      </footer>     </body>  </html>  This is very simple HTML markup. I have styled this markup using CSS.The contents of the style.css file follow* {    margin: 0;    padding: 0;}header{font-family:Tahoma;font-size:1.3em;color:#505050;text-align:center;}#tabs {    font-size: 0.9em;    margin: 20px 0;}#tabs ul {    float: left;    background: #777;    width: 260px;    padding-top: 24px;}#tabs li {    margin-left: 8px;    list-style: none;}* html #tabs li {    display: inline;}#tabs li, #tabs li a {    float: left;}#tabs ul li.active {    border-top:2px red solid;    background: #15ADFF;}#tabs ul li.active a {    color: #333333;}#tabs div {    background: #15ADFF;    clear: both;    padding: 15px;    min-height: 200px;}#tabs div h3 {    margin-bottom: 12px;}#tabs div p {    line-height: 26px;}#tabs ul li a {    text-decoration: none;    padding: 8px;    color:#0b2f20;    font-weight: bold;}footer{background-color:#999;width:100%;text-align:center;font-size:1.1em;color:#002233;}There are some CSS rules that style the various elements in the HTML 5 file.

  • Converting from different handedness coordinate systems

    - by SirYakalot
    I am currently porting a demo from XNA to DirectX which, as I understand it, both have coordinate systems with different handednesses. What are the things I need to bare in mind when converting between the two? I understand not everything needs to be changed. Also I notice that many of the 3D maths functions in some of the direct3D libraries have right handed and left handed alternatives. Would it be better to just use these?

  • How to Assign a Default Signature in Outlook 2013

    - by Lori Kaufman
    If you sign most of your emails the same way, you can easily specify a default signature to automatically insert into new email messages and replies and forwards. This can be done directly in the Signature editor in Outlook 2013. We recently showed you how to create a new signature. You can also create multiple signatures for each email account and define a different default signature for each account. When you change your sending account when composing a new email message, the signature would change automatically as well. NOTE: To have a signature added automatically to new email messages and replies and forwards, you must have a default signature assigned in each email account. If you don’t want a signature in every account, you can create a signature with just a space, a full stop, dashes, or other generic characters. To assign a default signature, open Outlook and click the File tab. Click Options in the menu list on the left side of the Account Information screen. On the Outlook Options dialog box, click Mail in the list of options on the left side of the dialog box. On the Mail screen, click Signatures in the Compose messages section. To change the default signature for an email account, select the account from the E-mail account drop-down list on the top, right side of the dialog box under Choose default signature. Then, select the signature you want to use by default for New messages and for Replies/forwards from the other two drop-down lists. Click OK to accept your changes and close the dialog box. Click OK on the Outlook Options dialog box to close it. You can also access the Signatures and Stationery dialog box from the Message window for new emails and drafts. Click New Email on the Home tab or double-click an email in the Drafts folder to access the Message window. Click Signature in the Include section of the New Mail Message window and select Signatures from the drop-down menu. In the next few days, we will be covering how to use the features of the signature editor next, and then how to insert and change signatures manually, backup and restore your signatures, and modify a signature for use in plain text emails.

    When I start Xchat, I note the issue: As you can see, the bottom edge of the window is covered by some other thing (in this case, it's firefox status bar, but if I have no other window opened, I see my desktop background in that position), so I reduce it with the maximize button on top left: Finally I maximize it again and obtain the wanted behaviour: Is this a bug or can I adjust it in any way?

  • Atmospheric scattering sky from space artifacts

    - by ollipekka
    I am in the process of implementing atmospheric scattering of a planets from space. I have been using Sean O'Neil's shaders from http://http.developer.nvidia.com/GPUGems2/gpugems2_chapter16.html as a starting point. I have pretty much the same problem related to fCameraAngle except with SkyFromSpace shader as opposed to GroundFromSpace shader as here: http://www.gamedev.net/topic/621187-sean-oneils-atmospheric-scattering/ I get strange artifacts with sky from space shader when not using fCameraAngle = 1 in the inner loop. What is the cause of these artifacts? The artifacts disappear when fCameraAngle is limtied to 1. I also seem to lack the hue that is present in O'Neil's sandbox (http://sponeil.net/downloads.htm) Camera position X=0, Y=0, Z=500. GroundFromSpace on the left, SkyFromSpace on the right. Camera position X=500, Y=500, Z=500. GroundFromSpace on the left, SkyFromSpace on the right. I've found that the camera angle seems to handled very differently depending the source: In the original shaders the camera angle in SkyFromSpaceShader is calculated as: float fCameraAngle = dot(v3Ray, v3SamplePoint) / fHeight; Whereas in ground from space shader the camera angle is calculated as: float fCameraAngle = dot(-v3Ray, v3Pos) / length(v3Pos); However, various sources online tinker with negating the ray. Why is this? Here is a C# Windows.Forms project that demonstrates the problem and that I've used to generate the images: https://github.com/ollipekka/AtmosphericScatteringTest/ Update: I have found out from the ScatterCPU project found on O'Neil's site that the camera ray is negated when the camera is above the point being shaded so that the scattering is calculated from point to the camera. Changing the ray direction indeed does remove artifacts, but introduces other problems as illustrated here: Furthermore, in the ScatterCPU project, O'Neil guards against situations where optical depth for light is less than zero: float fLightDepth = Scale(fLightAngle, fScaleDepth); if (fLightDepth < float.Epsilon) { continue; } As pointed out in the comments, along with these new artifacts this still leaves the question, what is wrong with the images where camera is positioned at 500, 500, 500? It feels like the halo is focused on completely wrong part of the planet. One would expect that the light would be closer to the spot where the sun should hits the planet, rather than where it changes from day to night. The github project has been updated to reflect changes in this update.

  • Unity desktop became transparent after installing VBox Guest Additions [closed]

    - by Stoune
    I have installed Ubuntu Desktop x64 12.01.1 as guest in VirtualBox. When I installed VirtualBox Guest Additions, Unity desktop (top bar and left program icons bar) becomes invisible. The problem was found in VirtualBox 4.1.20 and still exist in 4.1.22. Reinstalling doesn't help. Maybe someone knows how to overcome this issue?

  • Should I organize my folders by business domain or by technical domain?

    - by Florian Margaine
    For example, if I'm using some MVC-like architecture, which folder structure should I use: domain1/ controller model view domain2/ controller model view Or: controllers/ domain1 domain2 models/ domain1 domain2 views/ domain1 domain2 I deliberately left out file extensions to keep this question language-agnostic. Personally, I'd prefer to separate by business domain (gut feeling), but I see that most/many frameworks separate by technical domain. Why whould I choose one over the other?

  • Building a Flash Platformer

    - by Jonathan O
    I am basically making a game where the whole game is run in the onEnterFrame method. This is causing a delay in my code that makes debugging and testing difficult. Should programming an entire platformer in this method be efficient enough for me to run hundreds of lines of code? Also, do variables in flash get updated immediately? Are there just lots of threads listening at the same time? Here is the code... stage.addEventListener(Event.ENTER_FRAME, onEnter); function onEnter(e:Event):void { //Jumping if (Yoshi.y > groundBaseLevel) { dy = 0; canJump = true; onGround = true; //This line is not updated in time } if (Key.isDown(Key.UP) && canJump) { dy = -10; canJump = false; onGround = false; //This line is not updated in time } if(!onGround) { dy += gravity; Yoshi.y += dy; } //limit screen boundaries //character movement if (! Yoshi.hitTestObject(Platform)) //no collision detected { if (Key.isDown(Key.RIGHT)) { speed += 4; speed *= friction; Yoshi.x = Yoshi.x + movementIncrement + speed; Yoshi.scaleX = 1; Yoshi.gotoAndStop('Walking'); } else if (Key.isDown(Key.LEFT)) { speed -= 4; speed *= friction; Yoshi.x = Yoshi.x - movementIncrement + speed; Yoshi.scaleX = -1; Yoshi.gotoAndStop('Walking'); } else { speed *= friction; Yoshi.x = Yoshi.x + speed; Yoshi.gotoAndStop('Still'); } } else //bounce back collision detected { if(Yoshi.hitTestPoint(Platform.x - Platform.width/2, Platform.y - Platform.height/2, false)) { trace('collision left'); Yoshi.x -=20; } if(Yoshi.hitTestPoint(Platform.x, Platform.y - Platform.height/2, false)) { trace('collision top'); onGround=true; //This update is not happening in time speed = 0; } } }

  • How do I fix the problems I'm having with Xfce and Xubuntu?

    - by Noel Quiles
    I booted into a Xubuntu session and when the splash disappeared it left behind artifacts on the desktop. I went into Desktop to change the background but it stayed completely gray. Not only that, GTK isn't theming any of my windows, nor can I change GTK themes in the settings manager. I recently installed GTK+ 2.x alongside GTK+ 3 for a compatibility issue with xfce-battery-plugin, which also refuses to show anything but 0%. What is going on?
