  • How can I get VirtualBox Guest Additions installed in an Ubuntu 9.10 server?

    - by sutch
    I have a freshly installed Ubuntu 9.10 server installed within a VirtualBox VM instance. From the VirtualBox menu bar, I selected Devices: Install Guest Additions... Then performed the following commands: > sudo apt-get install -y build-essential linux-headers-$(uname -r) > sudo mount /dev/cdrom /mnt/ > sudo /mnt/VBoxLinuxAdditions-amd64.run After some successful looking results, the following error is displayed: Installing the Window System drivers ...fail! (Could not find the X.Org or XFree86 Window System.) After restarting, I was looking forward to some UI integration with my host desktop (resize window, not needing to press right-Ctrl to escape the client window, and having copy and paste functionality. Is it possible to install the Guest Additions without the X Window overhead (I plan to only use for shell commands)? If additional packages are required, which ones?

  • SEO Implications of creating Niche Product Blogs vs Main Company Blog with Categories.

    - by Frank
    Our company has a dilemma that I am hoping the users of Pro WebMasters can help us with. Right now as it stands we create a seperate website for each product that we sell. We also have our corporate site which lists each of these brands. For Example: www.Apple.com < --- main company site www.Ipad.com <--- Product www.Iphone.com <--- Product www.Imac.com <-- Product We are looking to build a wordpress blog mainly for the purpose of increasing our SEO rank. Here are our two options: SINGLE BLOG - On Our Corporate Domain http://apple.com/blog Each post is categoried http://apple.com/category/ipad/ipad-5-realeasd.htm Easier to manage than multiple blogs More content since its listing about all our products. ONE BLOG PER PRODUCT - on each site http://ipad.com/blog Each product has its own blog with only its own articles Harder to manage, but does it benefit SEO? Can the team here tell me the SEO benefits of either approach? Similar to Apple all the products our company sells are loosely related. Although its not likely that a customer of product A would be interested in product B.

  • local cache for NAS or network folder

    - by HugoRune
    I am planning to build a network attached storage (NAS) server. Is there a way to cache frequently acccessed files from the remote storage automatically on the local PC? (I am not looking for a way to sync whole folders like rsync, but rather something that automatically and transparently caches the last accessed 50 gb of files.) Ideally I am searching for something that caches writes as well as reads, since only one pc will be accessing the server (and one day of lost changes if the local cache is damaged would be acceptable) I looked into windows offline files, but as far as I could tell this requires manual interaction to disconnect the server or go into offline mode in order to use the cache. The server would probably be running Linux or freeNAS, the pc runs Windows xp, but could be upgraded to 7 if required.

  • MSDN article on jQuery Mobile

    - by Wallym
    My article on jQuery Mobile has been published.  Please check it out.There’s no doubt about it. Wherever developers look and whoever they talk to, mobile is at the top of the list. Talk to a C-level executive, and the conversation turns to mobile, and the question “How do I get me some of that?” comes up. Talk to other developers, and they tell you they’re targeting mobile devices. Mobile has become a big deal as smartphones have taken hold in the consumer marketplace.In the years leading up to the current focus on mobile applications and devices, Web developers have been adding more and more client-side functionality to their applications. You can see this in the use of client-side JavaScript libraries like jQuery.With the growth of the market for mobile devices, the ability to create applications that run across platforms is very important for developers and for businesses that are trying to keep their expenses in check. There are a set of applications, mostly in the area of content consumption (think Amazon.com), that run well in a mobile Web browser. Unfortunately, there are differences between Web browsers on various mobile devices. The goal of the recently introduced jQuery Mobile (jQM) library is to provide cross-browser support to allow developers to build applications that can run across the various mobile Web browsers and provide the same—or at least a very similar—user interface.The jQuery Mobile library was introduced in an alpha release in the fall of 2010 and released to manufacturing in November 2011. At the time of this writing, the current version of jQuery Mobile is 1.1.1. By the time you read this, jQuery Mobile will almost certainly have reached version 1.2.0. The library has been embraced by Microsoft, Adobe and other companies for mobile Web development. In August 2011, jQM had 32 percent market share compared with other mobile JavaScript frameworks such as iWebKit and jQTouch. This market share is impressive given that it started from zero little more than 12 months ago, and the 1.0 release is the first officially supported release.

  • LINQ: Enhancing Distinct With The PredicateEqualityComparer

    - by Paulo Morgado
    Today I was writing a LINQ query and I needed to select distinct values based on a comparison criteria. Fortunately, LINQ’s Distinct method allows an equality comparer to be supplied, but, unfortunately, sometimes, this means having to write custom equality comparer. Because I was going to need more than one equality comparer for this set of tools I was building, I decided to build a generic equality comparer that would just take a custom predicate. Something like this: public class PredicateEqualityComparer<T> : EqualityComparer<T> { private Func<T, T, bool> predicate; public PredicateEqualityComparer(Func<T, T, bool> predicate) : base() { this.predicate = predicate; } public override bool Equals(T x, T y) { if (x != null) { return ((y != null) && this.predicate(x, y)); } if (y != null) { return false; } return true; } public override int GetHashCode(T obj) { if (obj == null) { return 0; } return obj.GetHashCode(); } } Now I can write code like this: .Distinct(new PredicateEqualityComparer<Item>((x, y) => x.Field == y.Field)) But I felt that I’d lost all conciseness and expressiveness of LINQ and it doesn’t support anonymous types. So I came up with another Distinct extension method: public static IEnumerable<TSource> Distinct<TSource>(this IEnumerable<TSource> source, Func<TSource, TSource, bool> predicate) { return source.Distinct(new PredicateEqualityComparer<TSource>(predicate)); } And the query is now written like this: .Distinct((x, y) => x.Field == y.Field) Looks a lot better, doesn’t it?

  • Tools of the Trade

    - by Ajarn Mark Caldwell
    I got pretty excited a couple of days ago when my new laptop arrived. “The new phone books are here!  The new phone books are here!  I’m a somebody!” - Steve Martin in The Jerk It is a Dell Precision M4500 with an Intel i7 Core 2.8 GHZ running 64-bit Windows 7 with a 15.6” widescreen, 8 GB RAM, 256 GB SSD.  For some of you high fliers, this may be nothing to write home about, but compared to the 32–bit Windows XP laptop with 2 GB of RAM and a regular hard disk that I’m coming from, it’s a really nice step forward.  I won’t even bore you with the details of the desktop PC I was first given when I started here 5 1/2 years ago.  Let’s just say that things have improved.  One really nice thing is that while we are definitely running a lean and mean department in terms of staffing, my boss believes in supporting that lean staff with good tools in order to stay lean instead of having to spend even more money on additional employees.  Of course, that only goes so far, and at some point you have to add more people in order to get more work done, which is why we are bringing on-board a new employee and a new contract developer next week.  But that’s a different story for a different time. But the main topic for this post is to highlight the variety of tools that I use in my job and that you might find useful, too.  This is easy to do right now because the process of building up my new laptop from scratch has forced me to assemble a list of software that had to be installed and configured.  Keep in mind as you look through this list that I play many roles in our company.  My official title is Software Engineering Manager, but in addition to managing the team, I am also an active ASP.NET and SQL developer, the Database Administrator, and 50% of the SAN Administrator team.  So, without further ado, here are the tools and some comments about why I use them: Tool Purpose Virtual Clone Drive Easily mount an ISO image as a DVD Drive.  This is particularly handy when you are downloading disk images from Microsoft for your tools. SQL Server 2008 R2 Developer Edition We are migrating all of our active systems to SQL 2008 R2.  Developer Edition has all the features of Enterprise Edition, but intended for development use. SQL Server 2005 Developer Edition (BIDS ONLY) The migration to SSRS 2008 R2 is just getting started, and in the meantime, maintenance work still has to be done on the reports on our SQL 2005 server.  For some reason, you can’t use BIDS from 2008 to write reports for a 2005 server.  There is some different format and when you open 2005 reports in 2008 BIDS, it forces you to upgrade, and they can no longer be uploaded to a 2005 server.  Hopefully Microsoft will fix this soon in some manner similar to Visual Studio now allows you to pick which version of the .NET Framework you are coding against. Visual Studio 2010 Premium All of our application development is in ASP.NET, and we might as well use the tool designed for it. I’ve used a version of Visual Studio going all the way back to VB 6.0 and Visual Interdev. Vault Professional Client Several years ago we replaced Visual Source Safe with SourceGear Vault (then Fortress, and now Vault Pro), and I love it.  It is very reliable with low overhead - perfect for a small to medium size development team.  And being a small ISV, their support is exceptional. Red-Gate Developer Bundle with the SQL Source Control update for Vault I first used, and fell in love with, SQL Prompt shortly before Red-Gate bought it, and then Red-Gate’s first release made me love it even more.  SQL Refactor (which has since been rolled into the latest version of SQL Prompt) has saved me many hours and migraine’s trying to understand somebody else’s code when their indenting was nonexistant, or worse, irrational.  SQL Compare has been awesome for troubleshooting potential schema issues between different instances of system databases.  SQL Data Compare helped us identify the cause behind a bug which appeared in PROD but could not be reproduced in a nearly (but not quite exactly) identical copy in UAT.  And the newest tool we are embracing: SQL Source Control.  I blogged about it here (and here, and here) last December.  This is really going to help us keep each developer’s copy of the database in sync with one another. Fiddler Helps you watch the whole traffic stream on web visits.  Haven’t used it a lot, but it did help me track down some odd 404 errors we were finding in our own application logs.  Has some other JavaScript troubleshooting capabilities, but some of its usefulness has been supplanted by the Developer Tools option in IE8. Funduc Search & Replace Find any string anywhere in a mound of source code really, really fast.  Does RegEx searches, if you understand that foreign language.  Has really helped with some refactoring work to pinpoint, for example, everywhere a particular stored procedure is referenced, whether in .NET code or other SQL procedures (which we have in script files).  Provides in-context preview of the search results.  Fantastic tool, and a bargain price. SciTE SciTE is a Scintilla based Text Editor and it is a fantastic, light-weight tool for quickly reviewing (or writing) program code, SQL scripts, and extract files.  It has language-specific syntax highlighting.  I used it to write several batch and CMD programs a year ago, and to examine data extract files for exchanging information with other systems.  Extremely handy are the options to View End of Line and View Whitespace.  Ever receive a file that is supposed to use CRLF as an end-of-line marker, but really only has CRs?  SciTE will quickly make that visible. Infragistics Controls We do a lot of ASP.NET development, and frequently use the WebGrid, WebTab, and date picker controls.  We will likely be implementing the Hierarchical Data Grid soon.  Infragistics has control suites for WebForms, WinForms, Silverlight, and coming soon MVC/JQuery. WinZip - WITH Command-Line add-in The classic compression program with a great command-line interface that allows me to build those CMD (and soon PowerShell) programs for automated compression jobs.  Our versioned Build packages are zip files. XML Notepad Haven’t used this a lot myself, but one of my team really likes it for examining large XML files. LINQPad Again, haven’t used this one a lot, but it was recommended to me for learning and practicing my LINQ skills which will come in handy as we implement Entity Framework. SQL Sentry Plan Explorer SQL Server Show Plan on steroids.  Great for helping you focus on the parts of a large query that are of most importance.  Also great for just compressing the graphical plan into more readable layout. Araxis Merge A great DIFF and Merge tool.  SourceGear provides a great tool called DiffMerge that we use all the time, but occasionally, I like the cross-edit capabilities of Araxis Merge.  For a while, we also produced DIFF reports in HTML that showed all the changes that occurred between two releases.  This was most important when we were putting out very small, but very important hot fixes on a very politically hot system.  The reports produced by Araxis Merge gave the Director of IS assurance that we were not accidentally introducing ripples throughout the system with our releases. Idera SQL Admin Toolset A great collection of tools including a password checker to help analyze your SQL Server for weak user passwords, a Backup Status tool to quickly scan a large list of servers and databases to identify any that are overdue for backups.  Particularly helpful for highlighting new databases that have been deployed without getting included in your backup processing.  I also like Space Analyzer to keep an eye on disk space consumed by database files. Idera SQL Job Manager This free tool provides a nice calendar view of SQL Server Job Schedules, but to a degree, you also get what you pay for.  We will be purchasing SQL Sentry Event Manager later this year as an even better job schedule reviewer/manager.  But in the meantime, this at least gives me a good view on potential resource conflicts across multiple instances of SQL Server. DBFViewer 2000 I inherited a couple of FoxPro databases that I have to keep an eye on occasionally and have not yet been able to migrate them to SQL Server. Balsamiq Mockups We are still in evaluation-mode on this tool, but I really like it as a quick UI mockup tool that does not require Visual Studio, so someone other than a programmer can do UI design.  The interface looks hand-drawn which definitely has some psychological benefits when communicating to users, too. FeedDemon I have to stay on top of my WAY TOO MANY blog subscriptions somehow.  I may read blogs on a couple of different computers, and FeedDemon’s integration with Google Reader allows me to keep them all in sync.  I don’t particularly like the Google Reader interface, or the fact that it always wanted to mark articles as read just because I scrolled past them.  FeedDemon solves this problem for me, and provides a multi-tabbed interface which is good because fairly frequently one blog will link to something else I want to read, and I can end up with a half-dozen open tabs all from one article. Synergy+ In my office, I run four monitors across two computers all with one mouse and keyboard.  Synergy is the magic software that makes this work. TweetDeck I’m not the most active Tweeter in the world, but when I want to check-in with the Twitterverse, this really helps.  I have found the #sqlhelp and #PoshHelp hash tags particularly useful, and I also have columns setup to make it easy to monitor #sqlpass, #PASSProfDev, and short term events like #sqlsat68.   Whew!  That’s a lot.  No wonder it took me a couple of days to get everything setup the way I wanted it.  Oh, that and actually getting some work accomplished at the same time.  Anyway, I know that is a huge dump of info, and most people never make it here to the end, so for those who did, let me say, CONGRATULATIONS, you made it! I hope you’ll find a new tool or two to make your work life a little easier.

  • Introducing the Oracle Parcel Service&ndash;Example/Reference Application

    - by Jeffrey West
    Over the last few weeks the product management team has been working on a webcast series that is airing in EMEA.  It is a 5-episode series where we talk about different features of WebLogic and show how to build applications that take advantage of these features.  Each session is focused at a different layer of the technology stack, and you can find the schedule below. The application we are building in this series is named the ‘Oracle Parcel Service’.  It is an example application and not a product of Oracle by any stretch of the imagination.  Over the next few weeks we will be finalizing the code and will be releasing it for you to check out.  For updates, request membership to the Oracle Parcel Service project on SampleCode.oracle.com: https://www.samplecode.oracle.com/sf/projects/oracle-parcel-svc/. Here are some of the key features that we are highlighting: JPA 2.0 (new in WebLogic 10.3.4) with EclipseLink Coherence TopLink Grid Level 2 cache for JPA JAX-RS (new in WebLogic 10.3.4) 1.0 for RESTful services Lightweight JQuery Web UI for consuming RESTful services JSF 2.0 (new in WebLogic 10.3.4) utilizing PrimeFaces EJB 3.0 Spring-WS Web Services JAX-WS Web Services Spring MDP’s for Event Driven Architectures Java MDB’s for Event Driven Architectures Partitioned Distributed Topics for Event Driven Architectures   Accessing the Code on SampleCode.Oracle.com You will need to log in using your Oracle.com username and password.  If you have not created an account, you will need to do so.  It’s a simple one-page form and we don’t bother you with too many emails.   Please join the project to be kept up to date on changes to the code and new projects.  Joining the project is not required, but very much appreciated. Once you have signed in you should see an icon for accessing the Source Code via Subversion.  You can also download a zip file containing the code.

  • ODI 11g - Scripting a Reverse Engineer

    - by David Allan
    A common question is related to how to script the reverse engineer using the ODI SDK. This follows on from some of my posts on scripting in general and accelerated model and topology setup. Check out this viewlet here to see how to define a reverse engineering process using ODI's package. Using the ODI SDK, you can script this up using the OdiPackage and StepOdiCommand classes as follows;  OdiPackage pkg = new OdiPackage(folder, "Pkg_Rev"+modName);   StepOdiCommand step1 = new StepOdiCommand(pkg,"step1_cmd_reset");   step1.setCommandExpression(new Expression("OdiReverseResetTable \"-MODEL="+mod.getModelId()+"\"",null, Expression.SqlGroupType.NONE));   StepOdiCommand step2 = new StepOdiCommand(pkg,"step2_cmd_reset");   step2.setCommandExpression(new Expression("OdiReverseGetMetaData \"-MODEL="+mod.getModelId()+"\"",null, Expression.SqlGroupType.NONE));   StepOdiCommand step3 = new StepOdiCommand(pkg,"step3_cmd_reset");   step3.setCommandExpression(new Expression("OdiReverseSetMetaData \"-MODEL="+mod.getModelId()+"\"",null, Expression.SqlGroupType.NONE));   pkg.setFirstStep(step1);   step1.setNextStepAfterSuccess(step2);   step2.setNextStepAfterSuccess(step3); The biggest leap of faith for users is getting to know which SDK classes have to be used to build the objects in the design, using StepOdiCommand isn't necessarily obvious, once you see it in action though it is very simple to use. The above snippet uses an OdiModel variable named mod, its a snippet I added to the accelerated model creation script in the post linked above.

  • Are there any vendors making a Gigabit Fiber solution for laptops?

    - by romandas
    I'm trying to build a laptop system that can connect to just about any network you might come across in a large enterprise. I realize I can use a media converter to go from twisted pair to fiber but prefer to have a NIC instead of a converter. Is there a vendor out there that actually makes a gigabit ethernet fiber adapter for laptops? Edit: A year after I asked this question, apparently Allied Telesis came out with the AT-2872SX ExpressCard which has an SC connector for Gigabit Ethernet. See syneticon-dj's answer below.

  • 'Unblock' / 'Yellow Out' game questions

    - by pimvdb
    I would very much like to build a game that is known as 'Unblock' or 'Yellow Out'. It is a puzzle game in which the task is to move a car out of a parking space by moving other cars in certain directions. These are links where the game can be played: Yellow Out Unblock My questions concerning this game are: Is this game actually licensed? I see it's available under two names (perhaps even more). Does this mean the game idea can be used freely? Is there an article about it? I have not been able to find it on Wikipedia. I would like to gather some information about the game so as to understand more details of it. Is there some database with puzzles available? I can just check the puzzles of existing games, but that's a pain because I have to finish a level to get on to the following one. I was wondering whether there is a general list of puzzles somewhere. Thanks!

  • “Big Data” Is A Small Concept Unless You Can Apply It To The Customer Experience

    - by Michael Hylton
    There’s been a lot of recent talk in the industry about “big data”.  Much can be said about the importance of big data and the results from it, but you need to always consider the customer experience when analyzing and applying customer data. Personalization and merchandising drive the user experience.  Big data should enable you to gain valuable insight into each of your customers and apply that insight at the moment they are on your Web site, talking to one of your call center agents, or any other touchpoint.  While past customer experience is important, you need to combine that with what your customer is doing on your Web site now as well what they are doing and saying on social networking sites.  It’s key to have a 360 degree view of your customer across all of your touchpoints in order to provide that relevant and consistent experience that they come to expect when interacting with your brand. Big data can enable you to effectively market, merchandize, and recommend the right products to the right customers and the right time.  By taking customer data and applying it to product recommendations, you have an opportunity to gain a greater share of wallet through the cross-selling and up-selling of additional products and services.  You can also build sustaining loyalty programs to continue to engage with your customers throughout their long-term relationship with your brand.

  • Associating multiple data with a single entry in Open Office Base

    - by idyllhands
    I'm trying to build a database that I can use to track prices of groceries on certain dates. My problem is that I cannot figure out how to have a single entry associate with multiple data. For example, carrots. The index would be carrots. Then, a few categorizing fields (ie, Produce|Vegetable) Then, I can enter a price, date that the price was valid, store that was selling for said price, etc. And the next time I buy carrots, I can just add a new set of pricing data that would be associated with the original carrots entry. I know very little about database building, so if anyone has something I could just modify, I would greatly appreciate it. Alternatively, a step by step tutorial would be great.

  • Java Champion Jorge Vargas on Extreme Programming, Geolocalization, and Latin American Programmers

    - by Janice J. Heiss
    In a new interview, up on otn/java, titled “An Interview with Java Champion Jorge Vargas,” Jorge Vargas, a leading Mexican developer, discusses the process of introducing companies to Enterprise JavaBeans through the application of Extreme Programming. Among other things, he gives workshops about building code with agile techniques and creates a master project to build all apps based on Scrum, XP methods and Kanban. He focuses on building core components such as security, login, and menus. Vargas remarks, “This may sound easy, but it’s not—the process takes months and hundreds of hours, but it can be controlled, and with small iterations, we can translate customer requirements and problems of legacy systems to the new system.” In regard to his work with geolocalization, he says: “We have launched a beta program of Yumbling, a geolocalization-based app, with mobile clients for BlackBerry, iPhone, Android, and Nokia, with a Web interface. The first challenge was to design a simple universal mechanism providing information to all clients and to minimize maintenance provision to them. I try not to generalize a lot—to avoid low performance or misunderstanding in processing data. We use the latest Java EE technology—during the last five years, I’ve taught people how to use Java EE efficiently.” Check out the interview here.

Be prepared to show up at Friday night and start working in a team to write some great code. You can stay until Sunday night for the full event or you can leave early (in previous events, some developers did marathon coding sessions for multiple days straight – but those guys are insane). My wife, Ruth Walther, is the director of this year’s GiveCamp. She’ll be there and I’ll be there. I hope to see you at GiveCamp!

  • Is there a way to create a copy-on-write copy of a directory?

    - by BCS
    I'm thinking of a situation where I would have something that creates a copy of a directory, tweaks a few files, and then does some processing on the result. This wold be done fairly often, maybe a few dozen times a day. (The exact use case is testing patch submissions; dupe the code, patch it, build/test/report/etc.) What I'm looking for could be done by creating a new directory structure and populating it with hard links from the origonal. However this only works if all the tools you use delete and recreate files rather than edit them in place. Is there a way to have the file system do copy-on-write for a file? Note: I'm aware that many FSs use COW at a block level (all updates are done via writes to new blocks) but this is not what I want.

    - by dschinn1001
    here is ubuntu 12.10 virtual-box is somehow not working: I was trying to install win7 on to an usb-hard-disk. boinc is switched off and RAM-size is set to 4096 MB (too big ? of possible 8 Gibi ) report of virtual-box is: the com-object for virtualbox could not be created. the application is now ended. Start tag expected, '&lt;' not found. Location: '/home/$user/.VirtualBox/VirtualBox.xml', line 1 (0), column 1. /build/buildd/virtualbox-4.1.18-dfsg/src/VBox/Main/src-server/VirtualBoxImpl.cpp[484] (nsresult VirtualBox::init()). Fehlercode:NS_ERROR_FAILURE (0x80004005) Komponente:VirtualBox Interface:IVirtualBox {c28be65f-1a8f-43b4-81f1-eb60cb516e66} comment of me: why is virtualbox installing xml into folder of $user in .VirtualBox ? should it not be on usb-harddisk ? (with 500 Gibi ) first installation attempt was breaking off (with win7 in 64Bit) should I try virtual-box (ubuntu 64Bit) with win7 in 32Bit ? should I leave RAM-size of virtual-box to default 512 MB ? thanks for reply

  • Technical development decision for my newly established software company

    - by test test
    I have a new software company where I am planning to develop CRM system. So I have settled down on the technological approach I am going to use:- I will use an open source Java-based CRM engine. I will use a third party reporting tool named JasperReports for providing reports capabilities for the CRM. I will develop the interface and any customization which the customer might ask for using asp.net mvc framework since my knowledge and experience are based on asp.net. And I will use the CRM API to integrate my asp.net web application with the Java-based CRM. I have developed a simple demo which integrate these three main components (CRM engine, asp.net application and the reporting tool) and they worked well. But I am afraid of the following risk that I might face if I go with the above approach: I should hire developers with different skills and experience: Developers with Java skills to be able to modify the Java-based CRM and writing plug-ins -when needed- to extend the CRM capabilities. Other developers with asp.net skills to be able to build the application such as application forms, the portal from where users will be able to start the CRM processes, searching capabilities, etc. So might the above point raise some risks when I start hiring a new team and start building the CRM application, OR I am on the right track at this early stage?

  • specify temp folder for msi extracted files used for installation

    - by Binoj Antony
    I was recently installing Microsoft Windows SDK for Windows 7 and .NET Framework 3.5 SP1 to create my build server on a VM (Windows 2003 R2 Std), I was wondering that it would be nice to specify the temporary folder for the files being extracted by MSI for use during the installation. This should ideally work for any MSIs. I have some more virtual hard disks I have attached to this VMs, to point the temporary folder for MSI to one of these virtual hard disks would be quite productive since I can remove/discard this virtual hard disk later. Compacting the C drive VHD is a pain, and does not always reclaim space correctly. I tried changing the %temp% and tmp environment variable with no effect? Or is there any concrete/alternative solution to this type of problem? References: TempFolder Property ?? Windows Installer Wiki

  • NAS + XBMC combination

    - by Hendrik
    I currently own a WD Sharespace and I am not too happy about it. It will freeze constantly and its rather slow. I've been thinking of replacing it. I also own a WD HD Live, and it works like it is supposed to, but recently I've seen XBMC in action and I was quite impressed. I've been wondering lately about the possibility of replacing both products with one new device: a fast reliable nas which I can install XBMC on and is capable of rendering video and has an HDMI out. Do any such devices exist for sale or is the only way to build one from scratch? I've seen HTPC's for sale but I've never seen any of them with a raid setup. I've also read about building your own NAS with freeNAS but those setups dont allow you to run XBMC. Does anyone have experience with this?

  • should the same machine key be used in development and production environments?

    - by Henry Troup
    Our production servers all have the same machine key. However, our production and development systems do not have identical machine keys. We get heaps (about one per second) of exceptions of the form System.Security.Cryptography.CryptographicException: Padding is invalid and cannot be removed. at System.Security.Cryptography.RijndaelManagedTransform.DecryptData() at System.Security.Cryptography.RijndaelManagedTransform.TransformFinalBlock() at System.Security.Cryptography.CryptoStream.FlushFinalBlock() at System.Web.Configuration.MachineKeySection.EncryptOrDecryptData() at System.Web.UI.Page.DecryptStringWithIV()... We deploy the code after a build, .cs source is not present on production. aspx files are present on production. (Should I have posted in Stack Overflow? It's not a coding question.) From experimentation, we've found using the dev machine key value causes the exceptions to go away. Does anyone have documentation that I can use with the security team on the need for identical keys at compile and deployment time?
