• Exchange 2010 Autodiscover/OAB update issue

  - by bulldog5046

  Mid way through migration from 2003 to 2010 and with a few test users on 2010 i've noticed that the OAB is not being downloaded to outlook clients. I've checked the URL's are configured, addded both our CAS servers to the web based distribution list for the OAB and assigned the OAB to 2 mailbox databases we use but when i use outlook 'Test E-Mail AutoConfiguration' test i still see that the autodiscover says "OAB URL: Public Folder" even though i've now deselected the option. I've ran Test-OutlookWebServices to which i was getting an OAB error about no URL in the autodiscovery but having just re-ran it now appears fine, yey the autoconfigure test still does not. Does anyone have any idea why i'm getting this discrepency?

• What motherboard for a Core i7 920 Processor?

  - by jasondavis

  I am wanting to build a really nice PC, price is not to important as I will buy pieces every week or whatever it takes until I get everything I need. I am not a gamer but I would like to watch video and have 3-4 monitors. I do a lot of programming and use a lot of big programs so I would like to go all out and get a lot of Memory, probably at least 12gb but possibly more even as I see many boards support up to 24gb now. Will be using Windows 7. I have decided to go with the Core i7 920 Processor BX80601920. Based on what I posted above, can you please recommend some good motherboards I should look at ? Also some good places to purchase them online. Thanks for any help, tips, etc.

• Interactive command to let user change directory in bash

  - by Rich

  I am looking for a CURSES-based way (bash, c, doesn't really matter) of letting a user choose a folder or even a file in roughly the same way that they would do using Midnight Commander. I envisage using up/down for moving the cursor, esc to cancel, and enter to select the item under the cursor. If the item is a file, then return the full path to that file, if the item is a folder, change into that folder. Does anyone know of one that exists? If not, how would I go about writing one? I'm mainly a Java programmer, so I could use JavaCurses, but it feels a bit like overkill.

• Changing the Default Install Location of an MSI

  - by PSteele

  A few months ago, I had to tweak an MSI installer.  It was installing into a specific directory (named the same as the application) underneath Program Files.  Since the location of Program Files can change from machine to machine, the MSI has a special token you can use for Program Files (as well as for the application name).  So the current value for “DefaultLocation” of the Application Folder was: [ProgramFilesFolder]\[ProductName] During installation, these tokens would be replaced by the actual location based on the current machine. I needed to change this to a specific folder underneath the users My Documents directory.  I poked around the help file and I could not find where these special tokens (like “[ProgramFilesFolder]”) were defined.  Obviously, there must be some specific set of values that are available and I’m sure My Documents is one of them. I finally found them documented so I’m posting the link here.  Hopefully, it will help someone else out.  Not sure where I found this link… System Folder Properties For me, it was as easy as changing the DefaultLocation to: [PersonalFolder]\MyToolName\Application Technorati Tags: .NET,MSI

• How can I figure out which PHP extensions aren't being used?

  - by Tom Marthenal

  I manage a server (running Ubuntu) which hosts our client's sites with a few dozen different PHP-based websites, mostly small sites but also some installations of CMSes and forums. I used the get_loaded_extensions() method to see what extensions I have loaded. To help streamline the server (remove unnecessary extensions to make upgrading easier and marginally improve speed), I'd like to remove extensions that aren't being used by any of the sites. I currently have 54 different extensions loaded. I can easily eliminate some of these from the list which I know are used, but others I am less sure about. Is there some way that I can see extensions which have not been used recently?

• Working with lots of cubes. Improving performance?

  - by Randomman159

  Edit: To sum the question up, I have a voxel based world (Minecraft style (Thanks Communist Duck)) which is suffering from poor performance. I am not positive on the source but would like any possible advice on how to get rid of it. I am working on a project where a world consists of a large quantity of cubes (I would give you a number, but it is user defined worlds). My test one is around (48 x 32 x 48) blocks. Basically these blocks don't do anything in themselves. They just sit there. They start being used when it comes to player interaction. I need to check what cubes the users mouse interacts with (mouse over, clicking, etc.), and for collision detecting as the player moves. Now I had a massive amount of lag at first, looping through every block. I have managed to decrease that lag, by looping through all the blocks, and finding which blocks are within a particular range of the character, and then only looping through those blocks for the collision detection, etc. However, I am still going at a depressing 2fps. Does anyone have any other ideas on how I could decrease this lag? Btw, I am using XNA (C#) and yes, it is 3d.

• Use Google Apps/Cloud Services as a Domain Controller Replacement

  - by user124548

  This is a Canonical Question about Cloud Services replacing Active Directory. Is it possible to use Google Apps or another Cloud Service as a replacement for a Windows Domain Controller (replacing my whole AD infrastructure)? Specifically, I want to remove our dependence on a local Windows Server; currently it acts as a Domain Controller with File and Print Services. I'd like to seamlessly replace this server with something based on hosted applications. I do not just want to move the server to a dedicated or collocated server. I have yet to figure out how to piece together printer/etc sharing. If anyone has any insight into this, it would be appreciated. The goal is to eventually move all my servers to the cloud then write up a case study on the whole affair.

• XML Rules Engine and Validation Tutorial with NIEM

  - by drrwebber

  Our new XML Validation Framework tutorial video is now available. See how to easily integrate code-free adaptive XML validation services into your web services using the Java CAMV validation engine. CAMV allows you to build fault tolerant content checking with XPath that optionally use SQL data lookups. This can provide warnings as well as error conditions to tailor your validation layer to exactly meet your business application needs. Also available is developing test suites using Apache ANT scripting of validations.  This allows a community to share sets of conformance checking test and tools . On the technical XML side the video introduces XPath validation rules and illustrates and the concepts of XML content and structure validation. CAM validation templates allow contextual parameter driven dynamic validation services to be implemented compared to using a static and brittle XSD schema approach.The SQL table lookup and code list validation are discussed and examples presented.Features are highlighted along with a demonstration of the interactive generation of actual live XML data from a SQL data store and then validation processing complete with errors and warnings detection.The presentation provides a primer for developing web service XML validation and integration into a SOA approach along with examples and resources. Also alignment with the NIEM IEPD process for interoperable information exchanges is discussed along with NIEM rules services.The CAMV engine is a high performance scalable Java component for rapidly implementing code-free validation services and methods. CAMV is a next generation WYSIWYG approach that builds from older Schematron coding based interpretative runtime tools and provides a simpler declarative metaphor for rules definition.

• What's a good tool for collecting statistics on filesystem usage?

  - by Kamil Kisiel

  We have a number of filesystems for our computational cluster, with a lot of users that store a lot of really large files. We'd like to monitor the filesystem and help optimize their usage of it, as well as plan for expansion. In order to this, we need some way to monitor how these filesystems are used. Essentially I'd like to know all sorts of statistics about the files: Age Frequency of access Last accessed times Types Sizes Ideally this information would be available in aggregate form for any directory so that we could monitor it based on project or user. Short of writing something up myself in Python, I haven't been able to find any tools capable of performing these duties. Any recommendations?

• Client/Server game even in solo: any big problem?

  - by Klaim

  I'm making a game which have strong basic design based on multiplayer but also should provide a really interesting and self-sufficient solo game. A bit like a real-time strategy game. The events and actions taken shouldn't be as massive and immediate as in a FPS, so you can also think the networking like for an RTS. It's a PC game, targetting Windows, MacOSX and Linux (Ubuntu & Fedora). It's programmed in C++, using a variety of open source libraries, so I have great (potential) control over the performances. So far I always considered that just making the game work with two applications, client & server, even in solo mode was ok. However, as I'm in the process of starting the network code I'm having doubts about if it's a good idea. I'm not a specialist so I might be missing something in my analysis. I see these pros and cons: Pros: The game works only one way so if I fix a bug it should apply on all game modes, whatever the distance with the server is; Basic networking issues would be detected early, including behaviour with the protection softwares (firewall) installed (i am not specialist so this might be wrong); Cons: I suppose that even if it should be really fast enough, networking client and server on the same computer would still be slower than no networking and message passing in (one) process memory. Maybe debugging would be more difficult? I don't have experience in this case but so far I assume that debugging with Visual Studio allows me to debug multiple process so it shouldn't be really different. Also, remote debugging. My question is: is there a big disadvantage that I missed? Or maybe there are advantages that I missed and that should encourage me to just continue with only client-server game sessions?

• Installation questions

  - by user12609425

  I've gotten a couple more questions about the installation process for Ops Center. "Can I install on any SPARC / X86 based platform?" Ops Center can run on Oracle Solaris on either architecture, or on Linux. The Certified Systems Matrix lists the supported OSes, and the Linux and Solaris install guides go into more detail about the hardware and OS requirements. "Can we install it on local zones or LDOMS?" Zones, yes; LDOMS, sort of. You can install the Enterprise Controller in a local zone. There are a few caveats, which are explained in the Preparing a Non-Global Zone section. You can also install a Proxy Controller in an Oracle Solaris 11 zone. Agent Controllers, which are the part of the infrastructure that's installed on managed systems, can be put on zones or LDOMS. "Do we need any dedicated network ports from all agent monitoring systems?"  Yes. The port requirements are covered in the Network Port Requirements and Protocols table, which is in the feature reference guide as well as in the install guides.

• Using VMware's ESXi, can I plug in 30 USB Wireless adapters and allow each of 30 VMs one?

  - by 31eee384

  I'm assuming ESXi will act very similarly to VMware Workstation or other products, so answers based on knowledge of those programs might also help. I want to plug in 30 USB Wireless or Ethernet adapters into my server, and let each VM access one and only one of these devices. Unfortunately, I don't have the hardware to just try it out as the purchase of hubs and adapters hinges on the result of this question. The answer could be a resounding "yes, easy!" and that would be great. I couldn't find any answers to this question with google, and it's possible that this is because it's so easy to do.

• What is a Relational Database Management System (RDBMS)?

  A Relational Database Management System (RDBMS)  can also be called a traditional database that uses a Structured Query Language (SQL) to provide access to stored data while insuring the integrity of the data. The data is stored in a collection of tables that is defined by relationships between data items. In addition, data permitted to be joined in new relationships. Traditional databases primarily process data through transactions called transaction processing. Transaction processing is the methodology of grouping related business operations based predefined business events. An example of this can be seen when a person attempts to purchase an item from an online e-tailor. The business must execute specific operations for a related  business event. In this case, a business must store the following information: Customer Info, Order Info, Order Item Info, Customer Payment Data, Payment Results, and Current Order Status. Example: Pseudo SQL Operations needed for processing an online e-tailor sale. Insert Customer into Customers Insert New Order into Orders Insert Each New Order Item into OrderItems Insert Customer Payment Info into PaymentInfo Insert Payment Processing Result into PaymentDetails Update Customer for Current Order Status Common Relational Database Management System Microsoft SQL Server Microsoft Access Oracle MySQL DB2 It is important to note that no current RDBMS has fully implemented all of the Relational Principles. Common RDBMS Traits Volatile Data Supports Transaction Processing Optimized for Updates and Simple Queries

• Computer Invisible On Domain

  - by Giawa

  Good afternoon, I'm sorry that this isn't a programming question specifically, but stackoverflow has been great at answering questions in the past, so I thought I'd give it a shot. One of our Linux users attempted to install Cygwin on our Windows Server 2008 Domain Controller. Now it is no longer possible to browse the domain and see all of the computers. For example, \\my_domain_name will just bring up a username/password dialog box (that will not accept any username or password, even the domain administrator) and no computers will ever be listed. However, I can still connect to computers based on their name or IP address. So \\eridanus or \\192.168.1.85 still work to connect to the shared directories of computers on our network. Does anyone know where I can find these settings? and how I can fix this problem? Thanks, Giawa

• JavaScript and the User Experience

  5 sites I commonly vist at home: Google.com Gmail.com Linkedin.com Capella.edu Codeplex.com All of the top 5 sites I visit at home use JavaScript and is applied in various ways for various reasons. Gmail and Google make use of Ajax to retrieve information without the user having to call another page. In addition, all 5 of the websites use JavaScript to enhance a user's experience. Examples of this can be found in content rotation on Capella's main site and the displaying and hiding of specific content sections from within our course room. Codeplex uses Ajax and JavaScript to show dynamic content on its homepage and allow users to page through the data. I think there use of JavaScript is well placed and enhances the viewing experience of the user because it reduces the amount of interaction a user has to perform for them to obtain information they are looking to see. I have used JavaScript in various ways. One of the most memorable ways was to enable an HTML table to be able to have its rows paged and sorted based on the values in each table row.

• Java game design question (graphical objects)

  - by vemalsar

  Hello Guys, I'm beginner in game development, in Java and here on this site too and I have a game design question. Please comment my idea: I have a main loop which call update and draw method. I want to use an ArrayList which store graphical objects, they have coordinate and image or text to draw and my game objects extends this class. In update, I can choose which objects should be put in the array and in draw method I'll display the elements of array on the screen. I'm using a buffer and draw first there, but it is not important now I guess...Here is a simple (not full) code, only the logic: public class GamePanel extends JPanel implements KeyListener { ArrayList<graphicalObjects> graphArray = new ArrayList<graphicalObjects>(); public void update() { //change the game scene, update the graphArray, process input etc. } public void draw() { //draws every element of graphArray to a JPanel } public static main(String[] args) { while(true) { update(); draw(); } } } My questions: Should have I use interface or abstract class for graphicalObjects? graphicalObjects class and the ArrayList really needs or there is some better solution? How to draw objects? They draw themself with their own method or in the draw method I have to draw manually based on graphicalObjects variables (x,y coordinates, image etc.)? If this conception is wrong, please suggest another one! All comments are welcome and sorry if this is dumb question, thanks!

• Good podcasting solution?

  - by burnso

  I simply ask for the best, most common and simple way to set up a podcast? Please, I need an answer so I can close this question? I run a joomla-based website for a small church and now need a simple, cheap and effective solution for an audio podcast. I am looking for a solution that will do the following: User uploads audio files to service (preferably not to our own site) that is cheap, fast and simple to use. Dropbox for example? Files are easily embeddable into Joomla website articles to be played on the spot (through simple-to-use and media player). Preferably through RSS feeds (to make it easy to update every week). Files are downloadable. Files are viewable on iPhones and other smartphones. Solution can be broadcasted via iTunes. Solution doesn't need a lot of extra, new third party software. I'd rather keep it simple and familiar than have it be a complete new system but with a steep learning curve. At the moment we use vimeo to host the podcast, through video files. But we'd like to move to something simpler that doesn't involve a series of difficult steps to upload the files to the web.

• Fault Handling Slides and Q&A by Vennester

  - by JuergenKress

  Fault Handling It is one thing to architect, design, and code the “happy flow” of your automated business processes and services. It is another thing to deal with situations you do not want or expect to occur in your processes and services. This session dives into fault handling in Oracle Service Bus 11g and Oracle SOA Suite 11g, based on an order-to-cash business process. Faults can be divided into business faults, technical faults, programming errors, and faulty user input. Each type of fault needs a different approach to prevent them from occurring or to deal with them. For example, apply User Experience (UX) techniques to improve the quality of your application so that faulty user input can be prevented as much as possible. This session shows and demos what patterns and techniques can be used in Oracle Service Bus and Oracle SOA Suite to prevent and handle technical faults as well as business faults. Q&A This section lists answers to the questions that were raised during the preview event. Q: Where can retries be configured in Oracle Service Bus? The retry mechanism is used to prevent faults caused by temporary glitches such as short network interruptions. A faulted message is resend (retried) and might succeed this time since the glitch has passed. Retries are an out-of-the-box feature that can be used in Oracle Service Bus and Oracle SOA Suite using the Fault Policy framework. By default, retries are disabled in Oracle Service Bus.

• Java and .NET cost of use [on hold]

  - by 1110

  I work with .NET technology stack for about 4 years. I am learning and enjoy working with ASP MVC framework and I never did anything serious in other languages. This is not the question like what is better (I read all similar questions). What interest me is the cost of switching. For example: If you are about to start a start-up company today and you are in my situation not too much money, some good idea that you think others will use and have a knowledge of .NET. In my head I have a few questions that I can't answer and I know that somebody with experience can: 1) Java & .NET hosting. Suppose shared hosting is not good enough anymore, your site has grown and you need more resources. How much Java services is cheaper compared to .NET? 2) I didn't follow hype about ORACLE will kill java long time. Does oracle show interest in investing in java. I mean is is safe to bet on java as a technology when starting start-up (basically did oracle show some will to destroy java platform)? 3) I am not sure what I am asking here. When you use Java you can use JEEE stack or Java with third party stack (spring, hibernate, maven etc.). I saw a lot of project that work with second option if web application is not enterprise level but social networking site for example which stack is best pick? Summary of this question is is it safe to jump in to Java learn it and build product based on it. It's not too hard for me to learn it. But how much can I get from it.

• Reverse proxy with SSL and IP passthrough?

  - by Paul

  Turns out that the IP of a much-needed new website is blocked from inside our organization's network for reasons that will take weeks to fix. In the meantime, could we set up a reverse proxy on an Internet-based server which will forward SSL traffic and perhaps client IPs to the external site? Load will be light. No need to terminate SSL on the proxy. We may be able to poison DNS so original URL can work. How do I learn if I need URL rewriting? Squid/apache/nginx/something else? Setup would be fastest on Win 2000, but other OSes are OK if that would help. Simple and quick are good since it's a temporary solution. Thanks for your thoughts!

• OGRE 3D: How to create very basic gameworld [on hold]

  - by skiwi

  I'm considering trying around to create an FPS (First person shooter), using the Ogre 3D engine. I have done the Basic Tutorials (except CEGUI), and have read through the Intermediate Tutorial, I understand some of the more advanced concepts, but I'm stuck with very simple concepts. First of all: I would want to use some tiles (square ones, with relative little height) as the floor, I guess I need to set up a loop to get those tiles done. But how would I go about creating those tiles exactly? Like making it to be their own mesh, and then I would need to find some texture. Secondly: I guess I can derive the camera and movement functions from the basic tutorial. But I'll be needing a "soldier" (anything does for now), what is the best way to create a moderately decent looking soldier? (Or obtain a decent one from an open library?) And thirdly: How can I ensure that the soldier is actually walking on the ground, instead of mid air? Will raycasting into the ground + adjust position based on that, suffice?

• Building an intranet

  - by WernerCD

  I'm researching for a project I'm going to be doing at work on the side... I work for a small hospital and we recently upgraded all the browsers inside our intranet to IE8 (Goodbye 6 :). We have a small, obsolete intranet built by someone who isn't a web designer... functional enough, but annoying to maintain and really sparse. What I'm wanting to do... is use a good framework. I'm looking for suggestions... I'm looking for something Windows IIS based. I'd love windows authentication - with the ability to delegate sub-sections of the website to managers. Right now it's my job to add/update/delete anything from the site... I'd like something not complicated that can be delegated to non-technical people. Like... the Cafeteria Manager should be able to update the menu without putting a ticket into me. She'd log into her computer, open the intranet (which would use her windows log-on to identify her) and have elevated privileges to edit her section of the intranet. If I have to "extend" a good framework to get Windows Authentication, I'll do it... but I'd prefer it to be baked in. What are some good frameworks, tools and places to start? While this isn't a "Huge" project... it's going to be bigger than the basic stuff I've done before and I'd like a good place to start.
