• Create Advanced Panoramas with Microsoft Image Composite Editor

  - by Matthew Guay

  Do you enjoy making panoramas with your pictures, but want more features than tools like Live Photo Gallery offer?  Here’s how you can create amazing panoramas for free with the Microsoft Image Composite Editor. Yesterday we took a look at creating panoramic photos in Windows Live Photo Gallery. Today we take a look at a free tool from Microsoft that will give you more advanced features to create your own masterpiece. Getting Started Download Microsoft Image Composite Editor from Microsoft Research (link below), and install as normal.  Note that there are separate version for 32 & 64-bit editions of Windows, so make sure to download the correct one for your computer. Once it’s installed, you can proceed to create awesome panoramas and extremely large image combinations with it.  Microsoft Image Composite Editor integrates with Live Photo Gallery, so you can create more advanced panoramic pictures directly.  Select the pictures you want to combine, click Extras in the menu bar, and select Create Image Composite. You can also create a photo stitch directly from Explorer.  Select the pictures you want to combine, right-click, and select Stitch Images… Or, simply launch the Image Composite Editor itself and drag your pictures into its editor.  Either way you start a image composition, the program will automatically analyze and combine your images.  This application is optimized for multiple cores, and we found it much faster than other panorama tools such as Live Photo Gallery. Within seconds, you’ll see your panorama in the top preview pane. From the bottom of the window, you can choose a different camera motion which will change how the program stitches the pictures together.  You can also quickly crop the picture to the size you want, or use Automatic Crop to have the program select the maximum area with a continuous picture.   Here’s how our panorama looked when we switched the Camera Motion to Planar Motion 2. But, the real tweaking comes in when you adjust the panorama’s projection and orientation.  Click the box button at the top to change these settings. The panorama is now overlaid with a grid, and you can drag the corners and edges of the panorama to change its shape. Or, from the Projection button at the top, you can choose different projection modes. Here we’ve chosen Cylinder (Vertical), which entirely removed the warp on the walls in the image.  You can pan around the image, and get the part you find most important in the center.  Click the Apply button on the top when you’re finished making changes, or click Revert if you want to switch to the default view settings. Once you’ve finished your masterpiece, you can export it easily to common photo formats from the Export panel on the bottom.  You can choose to scale the image or set it to a maximum width and height as well.  Click Export to disk to save the photo to your computer, or select Publish to Photosynth to post your panorama online. Alternately, from the File menu you can choose to save the panorama as .spj file.  This preserves all of your settings in the Image Composite Editor so you can edit it more in the future if you wish.   Conclusion Whether you’re trying to capture the inside of a building or a tall tree, the extra tools in Microsoft Image Composite Editor let you make nicer panoramas than you ever thought possible.  We found the final results surprisingly accurate to the real buildings and objects, especially after tweaking the projection modes.  This tool can be both fun and useful, so give it a try and let us know what you’ve found it useful for.

• Disabling Password and Key Login

  - by Matthew Miller

  I want to disable the login prompt to access the Passwords and Keys. Right clicking the prompt does not bring up a change password dialogue. Under Applications System Tools Preferences there is "Passwords and Keys" but right clicking that does not allow me to change the password either. There is no Password and Keys selection under Accessories. I used to be able to change the password to a blank character, which allowed it to automatically login, but there doesn't seem to be an option for that now. Using Gnome 3 in 12.10 Thank you

• How I might think like a hacker so that I can anticipate security vulnerabilities in .NET or Java before a hacker hands me my hat [closed]

  - by Matthew Patrick Cashatt

  Premise I make a living developing web-based applications for all form-factors (mobile, tablet, laptop, etc). I make heavy use of SOA, and send and receive most data as JSON objects. Although most of my work is completed on the .NET or Java stacks, I am also recently delving into Node.js. This new stack has got me thinking that I know reasonably well how to secure applications using known facilities of .NET and Java, but I am woefully ignorant when it comes to best practices or, more importantly, the driving motivation behind the best practices. You see, as I gain more prominent clientele, I need to be able to assure them that their applications are secure and, in order to do that, I feel that I should learn to think like a malevolent hacker. What motivates a malevolent hacker: What is their prime mover? What is it that they are most after? Ultimately, the answer is money or notoriety I am sure, but I think it would be good to understand the nuanced motivators that lead to those ends: credit card numbers, damning information, corporate espionage, shutting down a highly visible site, etc. As an extension of question #1--but more specific--what are the things most likely to be seeked out by a hacker in almost any application? Passwords? Financial info? Profile data that will gain them access to other applications a user has joined? Let me be clear here. This is not judgement for or against the aforementioned motivations because that is not the goal of this post. I simply want to know what motivates a hacker regardless of our individual judgement. What are some heuristics followed to accomplish hacker goals? Ultimately specific processes would be great to know; however, in order to think like a hacker, I would really value your comments on the broader heuristics followed. For example: "A hacker always looks first for the low-hanging fruit such as http spoofing" or "In the absence of a CAPTCHA or other deterrent, a hacker will likely run a cracking script against a login prompt and then go from there." Possibly, "A hacker will try and attack a site via Foo (browser) first as it is known for Bar vulnerability. What are the most common hacks employed when following the common heuristics? Specifics here. Http spoofing, password cracking, SQL injection, etc. Disclaimer I am not a hacker, nor am I judging hackers (Heck--I even respect their ingenuity). I simply want to learn how I might think like a hacker so that I may begin to anticipate vulnerabilities before .NET or Java hands me a way to defend against them after the fact.

• What stressors do programmers encounter on the job, and how do you deal with them? [closed]

  - by Matthew Rodatus

  Learning to manage stress is vital to staying healthy while working at any job. A necessary subtask is learning to recognize and limit the sources of stress. But, in the midst of the daily grind, it can be difficult to recognize sources of stress (especially for an intense, focused persona such as a programmer). What types of stressors should programmers look out for, and how can they be managed?

• Change The Windows 7 Start Orb the Easy Way

  - by Matthew Guay

  Want to make your Windows 7 PC even more unique and personalized?  Then check out this easy guide on how to change your start orb in Windows 7. Getting Started First, download the free Windows 7 Start Button Changer (link below), and extract the contents of the folder.  It contains the app along with a selection of alternate start button orbs you can try out.   Before changing the start button, we advise creating a system restore point in case anything goes wrong.  Enter System Restore in your Start menu search, and select “Create a restore point”. Please note:  We tested this on both the 32 bit and 64 bit editions of Windows 7, and didn’t encounter any problems or stability issues.  That said, it is always prudent to make a restore point just in case a problem did happen. Click the Create button… Then enter a name for the restore point, and click Create. Changing the Start Orb. Once this is finished, run the Windows 7 Start Button Changer as administrator by right-clicking on it and selecting “Run as administrator”.  Accept the UAC prompt that will appear. If you don’t run it as an administrator, you may see the following warning.  Click Quit, and then run again as administrator. You should now see the Windows 7 Start Button Changer.  On the left it shows what your current (default) start orb looks like inactive, when hovered over, and when selected.  Click the orb on the right to select a new start button. Here we browsed to the sample orbs folder, and selected one of them.  Let’s give Windows the Media Center orb for a start orb.  Click the orb you want, and then select open. When you click Open, your screen will momentarily freeze and your taskbar will disappear.  When it reappears, your computer will have gone from having the old, default Start orb style… …to your new, exciting Start orb!  Here it is default, and glowing when hovered over. Now, the Windows 7 Start Orb Changer will change, and show your new Start orb on the left side.  If you would like to revert to the default orb, simply click the folder icon to restore it.  Or, if you would like to change the orb again, restore the original first and then select a new one. The orbs don’t have to be round; here’s a fancy Windows 7 logo as the start button. The start orb change will work in the Aero and Aero basic (which Windows 7 Start uses) themes, but will not show up in the classic, Windows 2000 style themes.  Here’s how the new start button looks with the Aero Classic theme: There are tons of orbs available, including this cute smiley, so choose one that you like to make your computer uniquely yours. Conclusion This is a cute way to make your desktop unique, and can be a great way to make a truly personalized theme.  Let us know your favorite Start orb!

• Sounds to describe the weather?

  - by Matthew

  I'm trying to think of sounds that will help convey the time of day and weather condition. I'm not even sure of all the weather conditions I would consider, and some are obvious. Like if it's raining, the sound of rain. But then I'm thinking, what about for a calm day? If it's morning time, I could do birds chirping or something. Night time could be an owl or something. What are some good combinations of sounds/weather/time to have a good effect?

• problem with frustum AABB culling in DirectX

  - by Matthew Poole

  Hi, I am currently working on a project with a few friends, and I am trying to get frustum culling working. Every single tutorial or article I go to shows that my math is correct and that this should be working. I thought maybe posting here, somebody would catch something I could not. Thank you. Here are the important code snippets /create the projection matrix void CD3DCamera::SetLens(float fov, float aspect, float nearZ, float farZ) { D3DXMatrixPerspectiveFovLH(&projMat, D3DXToRadian(fov), aspect, nearZ, farZ); } //build the view matrix after changes have been made to camera void CD3DCamera::BuildView() { //keep axes orthoganal D3DXVec3Normalize(&look, &look); //up D3DXVec3Cross(&up, &look, &right); D3DXVec3Normalize(&up, &up); //right D3DXVec3Cross(&right, &up, &look); D3DXVec3Normalize(&right, &right); //fill view matrix float x = -D3DXVec3Dot(&position, &right); float y = -D3DXVec3Dot(&position, &up); float z = -D3DXVec3Dot(&position, &look); viewMat(0,0) = right.x; viewMat(1,0) = right.y; viewMat(2,0) = right.z; viewMat(3,0) = x; viewMat(0,1) = up.x; viewMat(1,1) = up.y; viewMat(2,1) = up.z; viewMat(3,1) = y; viewMat(0,2) = look.x; viewMat(1,2) = look.y; viewMat(2,2) = look.z; viewMat(3,2) = z; viewMat(0,3) = 0.0f; viewMat(1,3) = 0.0f; viewMat(2,3) = 0.0f; viewMat(3,3) = 1.0f; } void CD3DCamera::BuildFrustum() { D3DXMATRIX VP; D3DXMatrixMultiply(&VP, &viewMat, &projMat); D3DXVECTOR4 col0(VP(0,0), VP(1,0), VP(2,0), VP(3,0)); D3DXVECTOR4 col1(VP(0,1), VP(1,1), VP(2,1), VP(3,1)); D3DXVECTOR4 col2(VP(0,2), VP(1,2), VP(2,2), VP(3,2)); D3DXVECTOR4 col3(VP(0,3), VP(1,3), VP(2,3), VP(3,3)); // Planes face inward frustum[0] = (D3DXPLANE)(col2); // near frustum[1] = (D3DXPLANE)(col3 - col2); // far frustum[2] = (D3DXPLANE)(col3 + col0); // left frustum[3] = (D3DXPLANE)(col3 - col0); // right frustum[4] = (D3DXPLANE)(col3 - col1); // top frustum[5] = (D3DXPLANE)(col3 + col1); // bottom // Normalize the frustum for( int i = 0; i < 6; ++i ) D3DXPlaneNormalize( &frustum[i], &frustum[i] ); } bool FrustumCheck(D3DXVECTOR3 max, D3DXVECTOR3 min, const D3DXPLANE* frustum) { // Test assumes frustum planes face inward.

• Is it just me or is this a baffling tech interview question

  - by Matthew Patrick Cashatt

  Background I was just asked in a tech interview to write an algorithm to traverse an "object" (notice the quotes) where A is equal to B and B is equal to C and A is equal to C. That's it. That is all the information I was given. I asked the interviewer what the goal was but apparently there wasn't one, just "traverse" the "object". I don't know about anyone else, but this seems like a silly question to me. I asked again, "am I searching for a value?". Nope. Just "traverse" it. Why would I ever want to endlessly loop through this "object"?? To melt my processor maybe?? The answer according to the interviewer was that I should have written a recursive function. OK, so why not simply ask me to write a recursive function? And who would write a recursive function that never ends? My question: Is this a valid question to the rest of you and, if so, can you provide a hint as to what I might be missing? Perhaps I am thinking too hard about solving real world problems. I have been successfully coding for a long time but this tech interview process makes me feel like I don't know anything. Final Answer: CLOWN TRAVERSAL!!! (See @Matt's answer below) Thanks! Matt

• Is there an established or defined best practice for source control branching between development and production builds?

  - by Matthew Patrick Cashatt

  Thanks for looking. I struggled in how to phrase my question, so let me give an example in hopes of making more clear what I am after: I currently work on a dev team responsible for maintaining and adding features to a web application. We have a development server and we use source control (TFS). Each day everyone checks in their code and when the code (running on the dev server) passes our QA/QC program, it goes to production. Recently, however, we had a bug in production which required an immediate production fix. The problem was that several of us developers had code checked in that was not ready for production so we had to either quickly complete and QA the code, or roll back everything, undo pending changes, etc. In other words, it was a mess. This made me wonder: Is there an established design pattern that prevents this type of scenario. It seems like there must be some "textbook" answer to this, but I am unsure what that would be. Perhaps a development branch of the code and a "release-ready" or production branch of the code?

• Good Freelance models for web developers

  - by Matthew Underwood

  I am a web developer with four years of experience in PHP, MYSQL and experience in Javascript etc. One day I hope to develop a freelance career in web development. Areas of freelance that I am thinking of going towards includes Wordpress, Magento development along with bespoke applications. I am also thinking of doing some consultancy work for clients and businesses when I build up some more experience and technical knowledge. I want to offer a web development service to potential clients that plays on my strengths in what I know but most importantly has a market. Web development can cover so many subjects that its difficult to pick out the areas that have demand. I am also curious to find out if web developers offer services that bring in a monthly income e.g application maintenance or database maintenance? Is there a market for certain areas like WordPress plugins or bespoke applications? Are there certain things to avoid because of work duration, unrealistic client expectations or the fact that its impossible to find a market for it? As professional and experienced freelance web developers have you learned some important do's and don'ts? Is there certain services that the majority of web developers offer because its in high demand? This is the one area of web development freelancing that I cant get my head around. I know there is never a definitive answer but there must be some good practises and general consensus on this subject. Web designers design websites they offer a lump sum and get paid monthly sometimes to add new content, PPC and SEO consultants market sites to the top this will involve monthly payments, web development doesn’t seem so clear cut.

• Discover What Powers Your Favorite Websites

  - by Matthew Guay

  Have you ever wondered if the site you’re visiting is powered by WordPress or if the webapp you’re using is powered by Ruby on Rails?  With these extensions for Google Chrome, you’ll never have to wonder again. Geeks love digging under the hood to see what makes their favorite apps and sites tick.  But opening the “View Source” window today doesn’t tell you everything there is to know about a website.  Plus, even if you can tell what CMS is powering a website from its source, it can be tedious to dig through lines of code to find what you’re looking for.  Also, the HTML code never tells you what web server a site is running on or what version of PHP it’s using.  With three extensions for Google Chrome you’ll never have to wonder again.  Note that some sites may not give as much information, but still, you’ll find enough data from most sites to be interesting. Discover Web Frameworks and Javascript Libraries with Chrome Sniffer If you want to know what CMS is powering a site or if it’s using Google Analytics or Quantcast, this is the extension for you.  Chrome Sniffer (link below) identifies over 40 different frameworks, and is constantly adding more.  It shows the logo of the main framework on the site on the left of your address bar.  Here wee see Chrome Sniffer noticed that How-To Geek is powered by WordPress.   Click the logo to see other frameworks on the site.  We can see that the site also has Google Analytics and Quantcast.  If you want more information about the framework, click on its logo and the framework’s homepage will open in a new tab. As another example, we can see that the Tumblr Staff blog is powered by Tumblr (of course), the Discus comment system, Quantcast, and the Prototype JavaScript framework. Or here’s a site that’s powered by Drupal, Google Analytics, Mollom spam protection, and jQuery.  Chrome Sniffer definitely uncovers a lot of neat stuff, so if you’re into web frameworks you’re sure to enjoy this extension. Find Out What Web Server The Site is Running On Want to know whether the site you’re looking at is running on IIS or Appache?  The Web Server Notifier extension for Chrome (link below) lets you easily recognize the web server a site is running on by its favicon on the right of the address bar.  Click the icon to see more information. Some web servers will show you a lot of information about their server, including version, operating system, PHP version, OpenSSL version, and more. Others will simply tell you their name. If the site is powered by IIS, you can usually tell the version of Windows Server its running on since the IIS versions are specific to a version of Windows.  Here we see that Microsoft.com is running on the latest and greatest – Windows Server 2008 R2 with IIS 7.5. Discover Web Technologies Powering Sites Wondering if a webapp is powered by Ruby on Rails or ASP.NET?  The Web Technology Notifier extension for Chrome (link below), from the same developer as the Web Server Notifier, will let you easily discover the backend of a site.  You’ll see the technology’s favicon on the right of your address bar, and, as with the other extension, can get more information by clicking the icon. Here we can see that Backpack from 37signals is powered by the Phusion Passenger module to run Ruby on Rails.   Microsoft’s new Docs.com Office Online apps is powered by ASP.NET…   And How-To Geek has PHP running to power WordPress. Conclusion With all these tools at hand, you can find out a lot about your favorite sites.  For example, with all three extensions we can see that How-To Geek runs on WordPress with PHP, uses Google Analytics and Quantcast, and is served by the LightSpeed web server.  Fun info, huh?   Links Download the Chrome Sniffer extension Download the Web Server Notifier extension Download the Web Technology Notifier extension Similar Articles Productive Geek Tips Enjoy a Clean Start Page with New Tab PageEnjoy Image Zooming on Your Favorite Photo Websites in ChromeAdd Your Own Folders to Favorites in Windows 7Find User Scripts for Your Favorite Websites the Easy WayAdd Social Elements to Your Gmail Contacts with Rapportive TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips Xobni Plus for Outlook All My Movies 5.9 CloudBerry Online Backup 1.5 for Windows Home Server Snagit 10 tinysong gives a shortened URL for you to post on Twitter (or anywhere) 10 Superb Firefox Wallpapers OpenDNS Guide Google TV The iPod Revolution Ultimate Boot CD can help when disaster strikes

• grub/burg listing a lot of os's

Each of the ubuntu installations also list something extra (maybe like a safe mode?) within grub. Firstly, how do I remove the ubuntu installations I don't use? (how do I first identify the one I do use? I log into it after booting it, but how do I delete the others) Also, how do I leave just a Windows 7 option and an Ubuntu option?

• DNS query re website Status: inactive

  - by Matthew Brookes

  There is a website that I am assisting with which, when you do a DNS look up on Who.is, returns a Website Status of "inactive". I also noticed the server type is incorrectly reported. This is not a website I generally use for DNS queries so am unsure if it is reliable. Using other DNS checking services reports what Iwould expect and the site is functioning correctly. Research I have done with regard to Website Status: inactive suggests an issue with the DNS configuration? I am looking for help understanding if this is something to be concerned with and if possible how to update this value or how it gets set in the first place.

• Moving Character in C# XNA Not working

  - by Matthew Stenquist

  I'm having trouble trying to get my character to move for a game I'm making in my sparetime for the Xbox. However, I can't seem to figure out what I'm doing wrong , and I'm not even sure if I'm doing it right. I've tried googling tutorials on this but I haven't found any helpful ones. Mainly, ones on 3d rotation on the XNA creators club website. My question is : How can I get the character to walk towards the right in the MoveInput() function? What am I doing wrong? Did I code it wrong? The problem is : The player isn't moving. I think the MoveInput() class isn't working. Here's my code from my character class : using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Graphics; using Microsoft.Xna.Framework.Input; namespace Jumping { class Character { Texture2D texture; Vector2 position; Vector2 velocity; int velocityXspeed = 2; bool jumping; public Character(Texture2D newTexture, Vector2 newPosition) { texture = newTexture; position = newPosition; jumping = true; } public void Update(GameTime gameTime) { JumpInput(); MoveInput(); } private void MoveInput() { //Move Character right GamePadState gamePad1 = GamePad.GetState(PlayerIndex.One); velocity.X = velocity.X + (velocityXspeed * gamePad1.ThumbSticks.Right.X); } private void JumpInput() { position += velocity; if (GamePad.GetState(PlayerIndex.One).Buttons.A == ButtonState.Pressed && jumping == false) { position.Y -= 1f; velocity.Y = -5f; jumping = true; } if (jumping == true) { float i = 1.6f; velocity.Y += 0.15f * i; } if (position.Y + texture.Height >= 1000) jumping = false; if (jumping == false) velocity.Y = 0f; } public void Draw(SpriteBatch spriteBatch) { spriteBatch.Draw(texture, position, Color.White); } } }

• Ruby on Rails background API polling

  - by Matthew Turney

  I need to integrate a free/busy calendar integration with Zimbra. Unlike outlook, it seems, Zimbra requires polling their API. I need to be able to grab the free/busy data in background tasks for 10's of thousands of users on a regular time interval, preferably every few minutes. What would be the best way to implement this in a Rails application without bogging down our current resque tasks? I have considered moving this process to something like node.js or something similar in Ruby. The biggest problem is that we have no control over the IO, as each clients Zimbra instances could be slow and we don't want to create a huge backup in tasks. Thoughts and ideas?

• How can programming ability be used to help people in poverty?

  - by Matthew

  As a student studying Computer Science in college, I often hear from friends working on various humanitarian projects, and I want to do something myself. But it seems that programmers don't have as many obvious avenues to help out as, say, doctors or teachers. What are some ways in which programmers can put their talent to use for people in poverty. Disclaimer: I am not saying that programmers have some obligation to do this, merely that I want to. I apologize if this question is too subjective for this site--I am marking it community wiki just in case (edit: I can't figure out how to mark this as community wiki. Can someone help me out?).

• Exclusive use of a Jini server during long-running call

  - by Matthew Flint

  I'm trying to use Jini, in a "Masters/Workers" arrangement, but the Worker jobs may be long running. In addition, each worker needs to have exclusive access to a singleton resource on that machine. As it stands, if a Worker receives another request while a previous request is running, then the new request is accepted and executed in a second thread. Are there any best-practices to ensure that a Worker accepts no further jobs until the current job is complete? Things I've considered: synchronize the job on the server, with a lock on the singleton resource. This would work, but is far from ideal. A call from a Master would block until the current Worker thread completes, even if other Workers become free in the meantime unregister the Worker from the registry while the job is running, then re-register when it completes. Might work OK, but something doesn't smell right with this idea... Of course, I'm quite happy to be told that there are more appropriate technologies than Jini... but I wouldn't want anything too heavyweight, like rolling out EJB containers all over the place.

• Android Live Testing

  - by Matthew Dockerty

  I am making a game for android and in it I am using sensors which are not available in the emulator. At the moment I am connecting my device and transferring the apk, then installing to test but that is a pain to do, and I have gotten to the stage where I need to start logging values for debugging. I have gone into the run configs of my app and set it to prompt me to pick a device, but my device is never in the list when it is connected to my PC and I try to run it. How am I supposed to set it up to work properly? Thanks for the help.

• Why are Javascript for/in loops so verbose?

  - by Matthew Scharley

  I'm trying to understand the reasoning behind why the language designers would make the for (.. in ..) loops so verbose. For example: for (var x in Drupal.settings.module.stuff) { alert("Index: " + x + "\nValue: " + Drupal.settings.module.stuff[x]); } It makes trying to loop over anything semi-complex like the above a real pain as you either have to alias the value locally inside the loop yourself, or deal with long access calls. This is especially painful if you have two to three nested loops. I'm assuming there is a reason why they would do things this way, but I'm struggling with the reasoning.

• Lenovo e420s overheating

  - by Matthew

  I recently bought a Lenovo e420s and decided to install Ubuntu (first time). The interface is great, but the computer overheats horribly (the fan is on full all the time and the cpu temperature is much higher than in Windows). In other words, it's not a fan problem, but an OS problem. Does anybody have a fix that is implementable by a luddite? I'd like to use linux, but it's not possible if it turns my computer into a radiator. Thanks.

• What is the difference between Workcenters, Dashboards, and the Interaction Hub?

  - by Matthew Haavisto

  Oracle Open World has just concluded.  Over the course of the conference, we presented several sessions covering different aspects of the PeopleSoft user experience, including Workcenters, Dashboards, and the PeopleSoft Interaction Hub (formerly known as the PeopleSoft Applications Portal).  Although we've produced collateral on these features and covered them in sessions, it became apparent at the conference that customers still have many questions about the these products, including how they are licensed, how they are installed, what their various purposes are, and how they can be used together synergistically. Let's Start with Licensing and Installation As you may know, we've extended the restricted use license (RUL) for the Interaction Hub.  This grants customers with PeopleTools 8.52 licenses the right to install the Interaction Hub for free for use as specified in the Tools license notes.  Note that this means customers receive a restricted use license for the Interaction Hub that doesn't cost them an additional license fee, but it is a separate product, not part of PeopleTools or PeopleSoft applications, and is a separate installation.  This means customers must provide the infrastructure to install and run the Hub, just like any other application.  The benefits of using the Hub to unify your PeopleSoft user experience can be great.  PeopleSoft applications have not yet delivered instances of the Hub with their products, though they may in the future. Workcenters and Dashboards, on the other hand, are frameworks provided by PeopleTools.  No other license is required, and no additional installation of a separate product is needed (apart from PeopleTools and PeopleSoft applications).  PeopleSoft applications are delivering instances of the workcenters and dashboards with their products.  Some are available now, and more are coming in future releases.  These delivered workcenter and dashboard instances require no additional licenses, and no additional installations beyond Tools and the applications that provide them.  In addition, the workcenter and dashboard frameworks provided by PeopleTools can be used by customers to build their own workcenters and dashboards, and it's quite easy and simple to do so. What are Their Differences?  What Purposes do they Serve? Workcenters, Dashboards and the Interaction Hub appear somewhat similar.  They all contain pagelets, and have some visual characteristics in common.  However, their strengths and purposes are very different, and they were designed to provide different benefits to your PeopleSoft ecosystem. Workcenters and Dashboards have the following characteristics: Designed for specific roles Focus on the daily tasks of those roles Help to streamline the work performed most often Personal view of my work world Makes navigation and search easier and quicker, particularly for transactions and decision support Reports and data needed for day-to-day work Personalizable, but minimal Delivered by PS Apps, but can be altered by customer for their requirements Customers can create their own Workcenters can be used for guided processes  The Interaction Hub is designed to aggregate content from multiple applications, and is is used to unify the user experience of those applications.  It offers a rich, web site-based user experience, and is often used to provide access to infrequently performed activities like benefits enrollment, payroll inquiries, life event changes, onboarding, and so on. Full-featured and robust Centrally administered Pushed to large audience Broad info like Company News Infrequent activities like benefits, not day-to-day tasks Self-service, access to employer info Central launch point for other activities and can navigate to workcenters and dashboards Deployed by customers or consultants, instances not delivered by PeopleSoft (at this time) Content management Unified PS application navigation Although these products are quite different and serve different purposes in your PeopleSoft environment, they can be used together to provide a richer, more efficient and engaging user experience for your all your user communities.
