• Project Showcase: SaaS Web Apps Hits a Home Run with New SCMS Database

  - by Webgui

  We love seeing projects from start to finish, and we’re happy to share the latest example with you. Who: SaaS Web Apps – they use Software as a Service to create web applications that look and feel like desktop applications. What: SaaS Web Apps needed to build a Sports Contract Management System (SCMS) for one of its customers, Premier Stinson Sports. Why: The SCMS database is used for collecting, analyzing and recording college coach and athletic directors’ employment and contract data. The Challenge: Premier Stinson Sports works with a number of partners, each with its own needs and unique requirements. For example, USA Today uses the system to provide cutting edge news analysis while The National Sports Law Institute of Marquette University Law School uses it to for the latest sports contract data and student analysis. In addition, the system needed to be secure due to the sensitivity of the data; it was essential that the user security and permissions be easily configurable. As always, performance was a key factor, especially with the intense reporting and analytical capabilities for this project. Because of this, most of the processing had to be done on a dedicated server but the project called for the richness and responsiveness of a desktop application. The Solution: To execute the project, SaaS Web Apps used APS.Net-based Visual WebGui from Gizmox, combined with SQL Server 2008 and SQL Reporting Services. This combination resulted in a quick deployment for SaaS Web Apps’ customers. The Result: The completed project gave each partner the scalability and availability of a web application with the performance and security of a desktop application. As an example, USA Today pulls data from this database to give readers the latest sports stats – Salary analysis of 2010 Football Bowl Subdivision Coaches. And here’s a screenshot of the database itself. Great work, SaaS Web Apps!

• A tip: Updating Data in SharePoint 2010 using REST API

  - by Sahil Malik

  SharePoint 2010 Training: more information Here is a little tip that will save you hours of head scratching. See there are two ways to update data in SharePoint using REST based API. A PUT request is used to update an entire entity. If no values are specified for fields in the entity, the fields will be set to default values. A MERGE request is used to update only those field values that have changed. Any fields that are not specified by the operation will remain set to their current value.   Now, sit back and think about it. You are going to update the entire entity! Hmm. Which means, you need to a) specify every column value, and b) ensure that the read only values match what was supplied to you. What a pain in the donkey! So 99/100 times, a PUT request will give you a HTTP 500 internal server error occurred, which is just so helpful. Read full article ....

• 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.

• 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.

• Dropping the full-time high-pay gig - I need help choosing a smart path that I can rely on to produce enough to survive comfortably ($2,500 per month)

  - by Jeff V

  I have about 6 years of full time experience developing web applications and tools. I know perl, python, PHP, ruby, and a good deal of SQL and relational theory. I have never had to choose a self-employed path as I have always had full time work or a bank account (credit cards) to support a big project. I'm planning to move out of the country to an area that will not offer local employment, and need some advice on what to focus on. I want to move in no more than six months, I have enough savings to live for an additional six months, but I would like to conserve it as much as possible. I enjoy taking risks, so I'm not looking for discussion of whether this is a good idea or not. I want advice on the most reliable solution given my skill set. Some paths I'm considering: Learn objective-c and build quality Apple software. Develop subscription based web tools for SEO, or other Marketing applications Attempt to acquire freelance projects by developing a reputation within open source projects, freelancer.com, and other online communities The last time I left my job, I was building a startup (that went under), and missed out living in a beautiful place due to the amount of time I worked. I would like to work 30-40 hours per week max. I can dedicate 10-15 hours per week while at my current job to prepare and learn. A preemptive thanks for the advice...

• 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.

• SonicWALL NetExtender - Client Install?

  - by JArmani

  We are about to push out a new VPN solution for our organization. One of the beautiful things we saw in SonicWALL's SSL-VPN was the thin, browser-based solution of NetExtender. Does anybody have experience with this? My specific concern is that, at least in Windows 7 during testing, it prompts for admin credentials to install the ActiveX NetExtender plugin, which is standard for installing anything in a Windows domain environment. But doesn't this mean I actually have to go in and install the client on all domain laptops that will be using the VPN in the field? They wouldn't actually be able to simply visit the site and run the client, as advertised? By the way, we're using the SonicWALL NSA 3500 device. We do have ManageEngine's Desktop Central, which can push out software installations, but it usually has to be in the form of a .MSI package. Is there any solution to this, besides hitting up all my organization's computers?

• 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

• UDK - How to make sure a PhysicalMaterial mask actually works?

  - by tomacmuni

  Hello, I have been reading the documentation for UDK about physical materials and masks. I have my 1bit BMP mask, and the two physical material assets I want to shoot off in the black and white channels. I have applied my material to both a rigid body and to a skeletal mesh and neither apparently uses the mask. If I assign a regular physical material (one that doesn't use a mask) then it will work fine, but this defeats the point because it gives only one hit reaction. In the documentation it states that it is possible to extend a class on which we want to use a physical material based on the KActor class's usage. How to do that? Here is the quote: "The following properties [ie, ImpactEffect - Particle system to spawn at the point of impact + ImpactSound - Sound to play when an impact occurs] allow you to attach sounds and effects to physical collisions. These only work on classes which support them, which at the moment is only KActor. By looking at the implementation in KActor though, you can add this functionality to other classes (or you can subclass KActor)." Essentially, how to make sure a PhysicalMaterial mask actually works? What code could be added to a skeletal mesh class perhaps, to get it going? Any help appreciated.

• CentOS 6 init script doesn't work properly

  - by user711643

  I'm setting up my ruby production server based on CentOS 6. I need a process called god (which is a process monitoring tool) to start at boot. I'm using an init script that I found here. Just as stated in the guide I ran: chkconfig --add god and then chkconfig --level 345 god on After this if I run "service god start|restart" everything works. It loads the available configurations and brings up the related processes (if they are not running). Problem is it doesn't work at boot. If I reboot the system, then I do "ps -aux | grep god". At this point "god" is running but apparently it didn't load the configuration files. If i run again service god restart, it loads everything without problems. What am I doing wrong?

• Outlook 2010 search stopped working with Exchange 2007

  - by Steve Hiner

  The quick search feature in Outlook 2010 used to work fine. We switched the computers over from a workgroup so that they are on the domain with our new server. We then copied all the email from the old PST file into the new Exchange based folders. Since we did that 3 of the 4 computers can't search email using Outlook's awesome search boxes. One of them works perfectly fine. Any idea what might have happened? There are only 5 users on the network and it's a pretty burly server for such a small network, I can't imagine the server is still indexing their mail. Is the quick search something that has to be turned on or might it be related to the permissions change from a non-domain user to a standard domain user?

• How can I insert the quoted price of gold from kitco.com into my excel spreadsheet?

  - by Frank Computer

  kitco.com provides a realtime price quote for gold and other metals. I have a spreadsheet which makes calculations based on the price of gold and would like for this realtime value to automatically be updated on my excel sheet. I tried 'get external data' from a website but that didn't work. any ideas? EDIT ADDED: Kitco has a gadget called KCAST which displays realtime quotes on the Windows taskbar. I tried capturing those values from the taskbar but that didn't work either. Maybe if Kitco provided an API or feed, it could be done?

• Developing with Oracle ADF Mobile and ADF Business Components Backend

  - by Shay Shmeltzer

  It's great to finally have the Oracle ADF Mobile solution out there. If you are not familiar with ADF Mobile - it basically lets you build applications that run on iOS and Android devices using the concepts you already know - components based UI constructions (same idea as JSF), taskflows, data controls, Java and of course JDeveloper. I created one demo that shows how to build an on-device application that gets data from local Java files (that run on the device - yes we do Java on iOS too) - you can see it here. However, one thing many of you might be wondering is how can you get data from your database into these mobile applications. Well if you already built your data access with Oracle ADF Business Components then here is a two step video demo that shows you what to do. The steps are: 1. Expose ADF Business Components as Services 2. Create an ADF Mobile application that consumes the above services with the Web service data control Simple right? That's the whole point of ADF Mobile - making on device application development as simple as possible. Try it out on your device.

• Cloning from a given point in the snapshot tree

  - by Fat Bloke

  Although we have just released VirtualBox 4.3, this quick blog entry is about a longer standing ability of VirtualBox when it comes to Snapshots and Cloning, and was prompted by a question posed internally, here in Oracle: "Is there a way I can create a new VM from a point in my snapshot tree?". Here's the scenario: Let's say you have your favourite work VM which is Oracle Linux based and as you installed different packages, such as database, middleware, and the apps, you took snapshots at each point like this: But you then need to create a new VM for some other testing or to share with a colleague who will be using the same Linux and Database layers but may want to reconfigure the Middleware tier, and may want to install his own Apps. All you have to do is right click on the snapshot that you're happy with and clone: Give the VM that you are about to create a name, and if you plan to use it on the same host machine as the original VM, it's a good idea to "Reinitialize the MAC address" so there's no clash on the same network: Now choose the Clone type. If you plan to use this new VM on the same host as the original, you can use Linked Cloning else choose Full.  At this point you now have a choice about what to do about your snapshot tree. In our example, we're happy with the Linux and Database layers, but we may want to allow our colleague to change the upper tiers, with the option of reverting back to our known-good state, so we'll retain the snapshot data in the new VM from this point on: The cloning process then chugs along and may take a while if you chose a Full Clone: Finally, the newly cloned VM is ready with the subset of the Snapshot tree that we wanted to retain: Pretty powerful, and very useful.  Cheers, -FB

• How to convert non key, value java arguments to applet params? (args like -Xmx64m)

  - by bwizzy

  I'm trying to use xvpviewer (based on TightVNC) to VNC into my VMs running on Citirx XenServer. There are a couple of caveats required with trusting the certificate from XenServer which I've got working. Essentially I'm trying to convert the java command below (which works on the command line to launch VncViewer) for use in an applet that can be accessed via HTML page. java -Djavax.net.ssl.trustStore=/tmp/kimo.jks -Xmx64m -jar VncViewer.jar HOST "/console?ref=OpaqueRef:141f4204-2240-4627-69c6-a0c7d9898e6a&session_id=OpaqueRef:91a483c4-bc40-3bb0-121c-93f2f89acc3c" PORT 443 PROXYHOST1 192.168.0.5 PROXYPORT1 443 SocketFactory "HTTPSConnectSocketFactory" I know I can put the HOST, PORT etc arguments into param tags for the applet but I'm not sure how to apply the two initial argments.

• Different Servers for incoming mails

  - by André

  Hi everybody, not sure if what I want is possible so I´d appreciate any pointers. I have full control over the infrastructure (DNS and servers) Currently I receive mails for domain.tld. MX record for domain.tld is gw.domain.tld. gw then does some spam and virus checking and forwards the mails to the internal exchange server. GW is a Proxmox Mail Gateway Box (Free license) Now what I want is to distribute mails for different recipients to other mail servers. Basicly I only want [email protected] and [email protected] to go to the exchange as before, but all others go to a different mail server (based on linux). Any idea how I could achieve this?

• What language available on commodity web hosts would suit a C# developer? [closed]

  - by billpg

  Recognising its ubiquity on commodity web hosting services, I tried developing in PHP a few years ago. I really didn't like it, later deciding that life was too short for PHP. (In brief, having to put $ on variable names; mis-spelt variable names become new variables; converting non-numeric strings to integers without complaint; the need for an "and this time I mean it" comparison operator.) In my ideal world, commodity web hosts would all support C#/ASP.NET, my preferred web-development language and framework, but this is not my ideal world. Even Mono has barely made a dent on Linux based hosts. However, last time I moaned about PHP's ubiquity, someone followed up that this was no longer the case, and that many other languages are now commonly usable on web hosts too. What programming language; a. Would suit a developer who prefers C#. b. Is available to run on many web hosts.

• Throwing and catching exceptions in the same function/method

  - by usr

  I've written a function that asks a user for input until user enters a positive integer (a natural number). Somebody said I shouldn't throw and catch exceptions in my function and should let the caller of my function handle them. I wonder what other developers think about this. I'm also probably misusing exceptions in the function. Here's the code in Java: private static int sideInput() { int side = 0; String input; Scanner scanner = new Scanner(System.in); do { System.out.print("Side length: "); input = scanner.nextLine(); try { side = Integer.parseInt(input); if (side <= 0) { // probably a misuse of exceptions throw new NumberFormatException(); } } catch (NumberFormatException numFormExc) { System.out.println("Invalid input. Enter a natural number."); } } while (side <= 0); return side; } I'm interested in two things: Should I let the caller worry about exceptions? The point of the function is that it nags the user until the user enters a natural number. Is the point of the function bad? I'm not talking about UI (user not being able to get out of the loop without proper input), but about looped input with exceptions handled. Would you say the throw statement (in this case) is a misuse of exceptions? I could easily create a flag for checking validity of the number and output the warning message based on that flag. But that would add more lines to the code and I think it's perfectly readable as it is. The thing is I often write a separate input function. If user has to input a number multiple times, I create a separate function for input that handles all formatting exceptions and limitations.

• MS Marketing Strategy

  - by Aaron Kowall

  I found this week’s Windows Phone 8 event interesting.  Not just because it looks like some fantastic new features in the new OS but because of the wait for release.  If I were a Nokia shareholder (which I am not) I’d be very unhappy with MS announcing that Windows Phone 8 will NOT work with current hardware.  So, there are some very nice Lumia devices that are now end-of-life that have arrived relatively recently at carriers and retailers. I understand that MS needs to demonstrate progress against iOS and Android and that there is some Windows 8 tie-in that they are trying to capitalize (and MS IS still all about Windows).  However, it’s a bit of a kick to partners that have invested in the platform with pretty decent devices (Samsung, HTC and of course Nokia). Personally, I’m still using a Samsung Foucs.  I was seriously considering upgrading to a Lumia 900 (we just got Lync mobile available) but will now wait it out until new devices arrive with Windows 8.  If MS had waited to announce, I would happily have upgraded to the Lumia and when I found out it couldn’t be upgraded then that would be a gamble I took and lost and I’d live with it.  Now, however, I can see the future and know that waiting is the better option for me so that is 1 sale Nokia will miss out on.  Based on some chats I’ve seen on mobile forums I’m certainly far from the only one. I’m sure glad I’m not in charge of marketing at MS.  There are tough decisions to be made there and I’m pretty sure you piss somebody off regardless. Technorati Tags: WP8,Lumia,Nokia,Samsung

• HTML Manifest for Content Folios

  - by Kyle Hatlestad

  I recently worked on a project to create a custom content folio renderer in WebCenter Content. It needed to output the native files in the folio along with a manifest file in HTML format which would list the contents of the folio along with any designated metadata and a relative link to the file within the download.  This way a person could hand someone the folio download and it would be a self-contained package with all of the content and a single file to display the information on the contents.  The default Zip rendition of the folio will output the web-viewable version of the file with an HDA formatted file for each one. And unless you are fluent in HDA or have a tool to read them, they are difficult to consume. I thought this might be useful for others, so I'm posting a copy of the component here. Beyond the standard instructions for installing a component, there is an environment configuration file (folionativezipwithmanifestrenderer_environment.cfg) which has a couple of options. FolioMetadataManifestList - This is a comma separated list of metadata fields (system or custom) that should be included in the manifest file. FolioMetadataManifestUseOriginalFilename - (True or False) If set to True, the filenames in the zip file will be based on the original filename as it was checked into WebCenter Content.  If False, it will use the 'Name' of the item as defined within the Folio.  This is usually the Title of the item. The component also includes the source code, so feel free to use this as a reference for creating other interesting folios.

• Windows Server Backup 2008 - Language Incompatibilities?

  - by Chris Walters

  I have 2 Windows 2008 Server R2 machines - one is Japanese language based and the other English. When I try to connect from the English language server using Windows Server Backup (snap-in) I get the following message: "An internal error has occurred in the backup engine or the computer that you are connected to remotely is running a version of backup application that is not compatible with the version on your local computer" Both claim to be running Version 1 of Windows Server Backup. Is remote connection to non-identical language server OSs a known problem? Specifically this is seen when attempting the "Connect To Another Server" in the action pane of Windows Server Backup.

• Is it possible to push DNS search suffices from DNS server to client?

  - by Mark

  Our (active directory, windows-server-based) intranet used to be called "intranet", and DNS worked fine for windows machines and iPads/Android devices. We have changed it to be "apps.intranet", and it still works for windows machines, but no longer for iPads/Android devices. I think this is because out windows clients are configured to append .company.com when searching DNS, to make it a fully qualified lookup (this search suffix list is pushed to the PCs via AD group policies). I must admit, though, I don't know why it worked with just "intranet"! Does anyone know if it's possible to get DNS to "tell" the iPads/Android devices to append .company.com ... or how we can make it work some other way (but still using the multi-label, non-qualified DNS names) ? Thanks!

• When adding second processor to SQL Server, will it automatically balance the load?

  - by ddavis

  We have a SQL Server 2008 R2 (10.5) on a dedicated box with a single 2.4Ghz processor, which regularly runs at 70-80% CPU. We are going to be adding a significant number of users to the application and therefore want to add a second processor to the box (scale up). Will SQL Server automatically use the second processor to balance threads, or is there additional configuration that will need to be done? In other words, will adding the second processor drop my CPU usage to 35-40% per CPU, automatically balancing the load? Based on what I read here, it seems that it will: http://msdn.microsoft.com/en-us/library/ms181007.aspx However, I've read elsewhere that CPU performance gains can be made by assigning database tables to different filegroups, but I'm not sure we want to get that complicated at this point.

• Privileged command as part of cronjob

  - by user42756

  Hi, I'm facing a weired problem on a unix-based machine. Here is the story: I have a personal username/password on a unix machine with limited privileges. Whenever I need to execute some commands I have to substitute user using the su command, then I execute it normally. Now, I need to add a cronjob that uses such privileged commands so I added the cronjob on the crontab of the user I substituted to in order to have access to these commands. Strangely, it turned out to me that these commands fail to run for some reason as a cronjob although when I execute them directly from shell (after su) they work seamlessly. Why does this happen? Why do these commands not work as part of cronjobs? Thank you

• 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.
