• Deployment Error: Silverlight 4.0 w/WCF RIA Services in ASP.NET MVC 2 App

  - by Dennis Ward

  I've got an MVC 2 App with an RIA Services link to a Silverlight Application. On my local machine, all is well, but when I deploy to Discount ASP servers, neither the MVC controller nor the WCF RIA services called from silverlight function: A silverlight datagrid gets a load error: System.ServiceModel.DomainServices.Client.DomainOperationException: Load operation failed for query... The remote server returned an error NotFound. In the MVC page where I had a simple table that worked prior to adding an EF model and DomainDataSource, I now get the error: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information. This is very similar to an issue I had before, but after upgrading from the betas of WCF/Silverlight 4, but the fix I had added there doesn't seem to work any longer. The link for that issue is: SL4/MVC2/WCF RIA Services = Load Error I'm really struggling with deploying, and could use some help if anybody can shed any light on this. Thanks! Dennis

• Windows Web Server 2008 R2 Server Core local password complexity

  - by Dennis Allen

  How can I disable the local user account password complexity settings on Windows 2008 R2 "Server Core"? I am trying to migrate our windows 2003 web server to windows 2008 R2. I am trying to see if I can use the "Server Core" install, and it has been a very internet search intensive experience. What I can't find out how to do is to find out how to disable password complexity for local user accounts. While our user account generator currently creates nice strong passwords, there was a time when this was not the case and unfortunately forcing the users to change their password is not an option at this time. Any help greatly appreciated. Dennis

• javascript return function's data as a file

  - by Dennis

  I have a function in javascript called "dumpData" which I call from a button on an html page as **onlick="dumpData(dbControl);"* What it does is return an xml file of the settings (to an alert box right now). I want to return it to the user as a file download. Is there a way to create a button when click will open a file download box and ask the user to save or open it? (sorta of like right-clicking and save target as)... Or can it be sent to a php file and use export();? Not sure how I would send a long string like that to php and have it simple send it back as a file download. Dennis

• Last element not getting insert in Tree

  - by rdk1992

  So I was asked to make a Binary Tree in Haskell taking as input a list of Integers. Below is my code. My problem is that the last element of the list is not getting inserted in the Tree. For example [1,2,3,4] it only inserts to the tree until "3" and 4 is not inserted in the Tree. data ArbolBinario a = Node a (ArbolBinario a) (ArbolBinario a) | EmptyNode deriving(Show) insert(x) EmptyNode= insert(tail x) (Node (head x) EmptyNode EmptyNode) insert(x) (Node e izq der) |x == [] = EmptyNode --I added this line to fix the Prelude.Head Empty List error, after I added this line the last element started to be ignored and not inserted in the tree |head x == e = (Node e izq der) |head x < e = (Node e (insert x izq) der) |head x > e = (Node e izq (insert x der)) Any ideas on whats going on here? Help is much appreciated

• What’s the Difference Between Succession Management and Talent Reviews?

  - by HCM-Oracle

  By Marcie Van Houten Is there a difference or are they pieces of one holistic strategic talent process? And can you have one without the other?  First, let me give a quick definition of each.  Succession planning (or management) is about creating succession slates or talent pools in support of a critical job or position or sets thereof. And then using those plans to help mitigate risk and plan talent needs for the organization.  Talent reviews (known by other names often) are sets of meetings where managers and executives come together to review, discuss and often heatedly debate the merits and potential of their employees, and then place and sometimes calibrate that talent on a performance to potential matrix.  These are some of the most strategic conversations happening in conference rooms across the globe. I speak with a lot of organizations about their practices in this area and the answers to these questions are as varied and nuanced as there are organizations thinking about them.  Some are passionate about their talent review processes and have a very evolved and thoughtful approach.  They really know their people, where their talent is, and the opportunities they plan to offer them.  And to them that is their succession process.  They may never create a slate of named candidates for a job or assign employees to formal talent pools.   On the flip side there are other organizations that create slates and slates and often multiple talent pools to support their strategic positions.  Through these, they are able to mitigate the risk associated with having a key player leave their organization.  And for them, that is their succession process.  Some will start from the lower levels of their organization and roll up their succession plans, while other organizations only cover their top 200 executives and key positions with plans.  And then there are organizations that leverage some of all of these.  Ultimately, the goals are to increase employee engagement, reduce talent-related risk, ensure the right talent is aligned to the strategic initiatives and to drive business value.  The approaches are as unique as the organizations they represent and the business opportunities they are looking to seize upon.   And that's ok.  It's great in fact. Because one thing that is common is the recognition that the need to know your people and align your top talent to the future needs of the organization is mission critical. Sure, there are a set of commonly recognized best practices and guiding principles for all of this.  There is no one right or perfect answer.  And that is what makes this all so much darn fun.  With Talent Review and Succession Management from Oracle HCM Cloud, we’ve blended the ability to support your strategic talent review conversations with both succession plans and talent pools allowing for one very seamless and interactive process. So whether you create a lot of succession plans, only focus on talent pools, have a robust talent review process, or all of the above, Oracle has you covered. I’m looking forward to spending time with our customers at the upcoming OHUG Global Conference 2014 happening June 9-13 in Las Vegas.  It’s an opportunity for me to talk to customers about their business and how they are doing strategic talent processes like talent reviews and succession.  I hope to see you there.

• Distributed storage and computing

  - by Tim van Elteren

  Dear Serverfault community, After researching a number of distributed file systems for deployment in a production environment with the main purpose of performing both batch and real-time distributed computing I've identified the following list as potential candidates, mainly on maturity, license and support: Ceph Lustre GlusterFS HDFS FhGFS MooseFS XtreemFS The key properties that our system should exhibit: an open source, liberally licensed, yet production ready, e.g. a mature, reliable, community and commercially supported solution; ability to run on commodity hardware, preferably be designed for it; provide high availability of the data with the most focus on reads; high scalability, so operation over multiple data centres, possibly on a global scale; removal of single points of failure with the use of replication and distribution of (meta-)data, e.g. provide fault-tolerance. The sensitivity points that were identified, and resulted in the following questions, are: transparency to the processing layer / application with respect to data locality, e.g. know where data is physically located on a server level, mainly for resource allocation and fast processing, high performance, how can this be accomplished? Do you from experience know what solutions provide this transparency and to what extent? posix compliance, or conformance, is mentioned on the wiki pages of most of the above listed solutions. The question here mainly is, how relevant is support for the posix standard? Hadoop for example isn't posix compliant by design, what are the pro's and con's? what about the difference between synchronous and asynchronous opeartion of a distributed file system. Though a synchronous distributed file system has the preference because of reliability it also imposes certain limitations with respect to scalability. What would be, from your expertise, the way to go on this? I'm looking forward to your replies. Thanks in advance! :) With kind regards, Tim van Elteren

• Surface development: it&rsquo;s just like software development

  - by Dennis Vroegop

  Surface is magic. Everyone using it seems to think that way. And I have to be honest, after working for almost 2 years with the platform I still get that special feeling the moment I turn on the unit to do some more work. The whole user experience, the rich environment of the SDK, the touch, even the look and feel of the Surface environment is so much different from the stuff I’ve been working on all my career that I am still bewildered by it. But… and this is a big but.. in the end we’re still talking about a computer and that needs software to become useful. Deep down the magic of the Surface unit there is a PC somewhere, running Windows Vista and the .net framework 3.5. When you write that magic software that makes the platform come alive you’re still working with .net, WPF/XNA, C#, VB.Net and all those other tools and technologies you know so well. Sure, the whole user experience is different from what you’ve known. And the way of thinking about users, their interaction and the positioning of screen elements requires a whole new paradigm. And that takes time. It took me about half a year before I had the feeling I got it nailed down. But when that moment came (about 18 months ago…) I realized that everything I had learned so far on software development still is true when it comes to Surface. The last 6 months I have been working with some people with a different background to start a new company. The idea was that the new company would be focussing on Surface and Surface only. These people come from a marketing background and had some good ideas for some applications. And I have to admit: their ideas were good. Very good. Where it all fell down of course is that these ideas need to be implemented in a piece of software. And creating great software takes skilled developers and a lot of time and money. That’s where things went wrong: the marketing guys didn’t realize and didn’t want to realize that software development is a job that takes skill. You can’t just hire a bunch of developers and expect them to deliver the best sort of software, especially not when it comes to Surface. I tried to explain that yes, their User Interface in Photoshop looked great, but no: I couldn’t develop an application like that in a weeks time. Even worse: the while backend of the software (WCF for communications, SQL Server for the database, etc) would take a lot more time than the frontend. They didn’t understand. It took them a couple of days to drawn the UI in Photoshop so in Blend I should be able to build the software in about the same amount of time. Well, you and I know that it doesn’t work that way. Software is hard to write, and even harder to write well, and it takes skill and dedication. It’s not something you can do as fast as you can draw a mock up for a Surface application in Photohop. The same holds true for web applications of course. A lot of designers there fail to appreciate the hard work that goes into writing the plumbing for a good web app that can handle thousands of users. Although the UI is very important, it’s not all there is to it. And in Surface development this is the same. The UI should create the feeling of magic, but the software behind it is what makes it come alive. And that takes time. A lot of time. So brush of you skills and don’t throw them away if you start developing for Surface. Because projects (and colaborations) can fail there as hard as they can in any other area of software development. On a side note: we decided to stop the colaboration (something the other parties involved didn’t appreciate and were very angry about) and decided to hire a designer for the Surface projects. The focus is back where it belongs: on the software development we know so well and have been doing very well for 13 years. UI is just a part of the whole project and not the end product. So my company Detrio is still going strong when it comes to develivering Surface solutions but once again from a technological background, not a marketing background.

• Windows Phone appointment task

  - by Dennis Vroegop

  Originally posted on: http://geekswithblogs.net/dvroegop/archive/2014/08/10/windows-phone-appointment-task.aspxI am currently working on a new version of my AgeInDays app for Windows Phone. This app calculates how old you are in days (or weeks, depending on your preferences). The inspiration for this app came from my father, who once told me he proposed to my mother when she was 1000 weeks old. That left me wondering: how old in weeks or days am I? And being the geek I am, I wrote an app for it. If you have a Windows Phone, you can find it at http://www.windowsphone.com/en-in/store/app/age-in-days/7ed03603-0e00-4214-ad04-ce56773e5dab A new version of the app was published quite quickly, adding the possibility to mark a date in your agenda when you would have reached a certain age. Of course the logic behind this if extremely simple. Just take a DateTime, populate it with the given date from the DatePicker, then call AddDays(numDays) and voila, you have the date. Now all I had to do was implement a way to store this in the users calendar so he would get a reminder when that date occurred. Luckily, the Windows Phone SDK makes that extremely simple: public void PublishTask(DateTime occuranceDate, string message) { var task = new SaveAppointmentTask() { StartTime = occuranceDate, EndTime = occuranceDate, Subject = message, Location = string.Empty, IsAllDayEvent = true, Reminder = Reminder.None, AppointmentStatus = AppointmentStatus.Free };   task.Show(); }  And that's it. Whenever I call the PublishTask Method an appointment will be made and put in the calendar. Well, not exactly: a template will be made for that appointment and the user will see that template, giving him the option to either discard or save the reminder. The user can also make changes before submitting this to the calendar: it would be useful to be able to change the text in the agenda and that's exactly what this allows you to do. Now, see at the bottom of the screen the option "Occurs". This tiny field is what this post is about. You cannot set it from the code. I want to be able to have repeating items in my agenda. Say for instance you're counting down to a certain date, I want to be able to give you that option as well. However, I cannot. The field "occurs" is not part of the Task you create in code. Of course, you could create a whole series of events yourself. Have the "Occurs" field in your own user interface and make all the appointments. But that's not the same. First, the system doesn't recognize them as part of a series. That means if you want to change the text later on on one of the occurrences it will not ask you if you want to open this one or the whole series. More important however, is that the user has to acknowledge each and every single occurrence and save that into the agenda. Now, I understand why they implemented the system in such a way that the user has to approve an entry. You don't want apps to automatically fill your agenda with messages such as "Remember to pay for my app!". But why not include the "Occurs" option? The user can still opt out if they see this happening. I hope an update will fix this soon. But for now: you just have to countdown to your birthday yourself. My app won't support this.

• Windows 8, the biggest struggle&hellip;.

  - by Dennis Vroegop

  As always, it’s hard to be original. It’s easy to copy great stuff others have done but to think of something nice that others might have done is not trivial. The number of applications in the Windows 8 Store is growing rappidly. That was to be expected; a lot of developers already have the skills needed to build Win8 apps so all it took was some ideas. And they have ideas. Another factor that helps with the growing number of apps in the store is the availability of the project templates in Visual Studio 2012. When you start a new project you are given a ready to run sample that you can adapt to your needs. All the stuff needed to navigate through the app, to display data, to do semantic zoom, it’s all available. So what do we do? We tweak, change, adapt and modify these samples to fit our application. However, the underlying structure of the app remains the same. Somehow developers can’t seem to break free from the structure that the sample apps give you. Result: all apps looks alike. My tip for the day: take the samples and use them to learn. Don’t use them as a foundation of your app. Make you app different from those others and you’ll find you will have something special. I’m curious to see what you come up with!

  ...Gab es da nicht mal ein gutes Oracle-Poster, wo man schnell nachschauen konnte und einen guten Überblick bekam? Viele Datenbankadministratoren haben das besagte Poster, das die Architektur und Prozesse sowie die Data Dictionary-Struktur der Oracle Datenbank beschreibt, vermisst! Daher wurde nun eine handliche kleine Flash-Applikation mit erweitertem Inhalt entwickelt - Oracle Database 11g: Interactive Quick Reference - die man sich hier downloaden kann (einfach auf den Button "Download now" klicken (Größe der Zip-Datei: 4.6 MB).

• Charms and the App Bar

  - by Dennis Vroegop

  Ok. I admit. I made a mistake in the last post about our planespotter app. I have dedicated a full part of the hub to Social. I also had a section called Friends but that made sense since I said that “Friends” is a special group of people that connect to each other through our app and only our app. Social however is sharing our spots with Twitter, Facebook and so on. Now, we could write that functionality in our app in a different section but there is one small problem with that: users don’t expect that. Ok, I admit. The mistake was quite deliberate to give me an excuse to write this part. But still: the mistake is one I see a lot. People are trying to do stuff in their application that they shouldn’t be doing. This always strike me as slightly odd: why do some work when others have already done it for you and you can just use it? After all: good developers are lazy (lazy people will always try to find the easiest way to do something and in development land this usually means the cleanest and best to support way…) So. What is that part that Microsoft has done for us and we don’t have to do ourselves? The answer lies on the right hand of your Win8 screen: This is a screenshot of my tablet (as you can see I am writing this right now….) When I swipe my finger from out of the screen on the right inside the screen (or move the mouse to the upper right corner) this menu will appear. Next to settings and the start menu button we’ll find the Search and the Share charms. These are two ways that your app can share the information it contains with the rest of the world, or at least: the rest of your system. So don’t write a Search feature in your app. Don’t write a Share feature in your app. It’s here already. Users, once they are used to Windows 8, will use that feature and expect it to work. If it doesn’t, they won’t like your app and you can kiss you dreams of everlasting fame goodbye. So use these two. What are they? Well, simply they are parts of a contract. In your app you say somewhere in code that you are supporting Search and Share. So when the user selects Share the system will interrogate the current app in the foreground if it supports this feature. Your app will say “But why, yes, I do!” Then the system will ask the app “Ok then, wisecrack, then share!” and you will have to provide the system with some information about the format. Other applications have subscribed to be at the receiving end of the Share contract. They have told the system that they support Sharing (receiving) and which formats they understand. If one or more of them support the formats you specify, the user will see them. The user clicks / taps on the app of their choice and data is moved from your app to the new one. So if you say you support Facebook and Twitter users can post data from your app to these networks by selecting Share. The same applies to Search. Don’t make a “search” button in your app but use the contract to tell the system that you support search and use that instead. Users will be grateful (remember that bar with men/women/creatures that are waiting for you?) The more and more people get to know Windows 8, the more they will use this. And if you are one of the people who wrote an app that helped them learn the system, well, that’s even better. So. We don’t have a Share or a Search button. We do have other buttons. Most important: we probably need a “New Spot” button. And a “Filter” might be useful. Or someway to open the camera so you can add a picture to the spot. Where will be put those? The answer is the “Appbar” . This is a application / context aware menu that slides up from the bottom of the screen when you move your finger / mouse from below the screen into it. From above downwards works just as well. Here you see an example of the appbar from the People app. (click on it for a larger version). This appears whenever you slide your finger up from below of down from above. This is where you put your commands. Remember, this is context aware so this menu will change when you are in different parts of your app or when you have selected different items. There are a few conventions when you create this appbar. First, the items on the right are “General” items, meaning they have little to do with what is on the screen right now. I think this would be a great place to add our “New Spot” icon. On the far left are items associated with the current selected item or screen. So if you have a spot selected, the button for Add Photo should be visible here and on the left hand side. Not everything is as clear as this, but this is what you should strive for. Group items together. And please note: this is the only place in Metro design where we are allowed to use lines as separators. So when you want to separate a group of icons from another group, add a line. Also note the simplicity of the buttons. No colors, no lights or shadows, no 3D. After a couple of years of fancy almost realistic looking icons people have finally decided that hey, this is a virtual world: it’s ok to look virtual as well. So make things as readable and clear as possible and don’t try to duplicate nature. It’s all about the information, remember? (If you don’t remember I’d like to point you to a older blog post of mine about the what and why of Metro). So.. think about the buttons a bit and think about Share and Search. What will you put there? Remember: this is the way the users interact with your apps and while you shouldn’t judge a book by its covers when it comes to people, this isn’t entirely so when it comes to apps. People DO judge an app by its looks and the way it feels. Take advantage of that. History has learned that a crappy app with a GREAT user interface gets better reviews than a GREAT app with a lousy UI… I know: developers will find this extremely unfair but that’s the world we live in (No, I am not saying you should deliver rubbish apps). Next time: we’ll start by building the darn thing!

• Everythings changes, except that it doesn&rsquo;t

  - by Dennis Vroegop

  You may have noticed this. Microsoft launched a new product this week. Well, launched is a strong word, they announced it. They call it.. The Surface! What is it? Well, it’s a cool looking family of tablets designed for Windows 8. And I have to say: they look stunning and I can’t wait to have one. There’s just one thing.. The name..Where have I heard that before? Why, indeed! Yes, it is also the name of a new paradigm in computing: Surface Computing. You may have read something about that, here on this blog for instance. Well, in order to prevent confusion they have decided to rename Surface to Pixelsense. You know, the technology that drives the ‘camera’ inside the Samsung SUR40 for Microsoft Surface…. So now, when we talk about Surface, we mean the new tablet. When we talk about Pixelsense we mean that big table… So there you have it… Welcome PixelSense! For more info see http://www.surface.com for the tablet and http://www.pixelsense.com for Pixelsense.

• apache domain redirect to subfolder

  - by Dennis

  I have a hosting account with godaddy. Its a linux system running apache. The way they do their setup is your primary domain is the root folder. When you add a subdomain its in a subfolder of the root which sucks. I want to setup a subfolder structure to organize my domains.. I called godday support and they said to use redirects.. but did not know how to do that.. How its setup now: primary domain: www.domain.com / sub.domain.com /sub I want to create a directory structure and then redirect to each but only show www.domain.com in the url www.domain.com /domain/www sub.domain.com /domain/sub I tried using: RewriteEngine On RewriteCond %{HTTP_HOST} ^(www.)?domain.com$ RewriteRule ^(/)?$ domain/www [L] but it just changes the url to www.domain.com/domain/www Can this be done in htaccess?

• URL rewrite and domain frame

  - by Dennis

  I have registered the domain www.posti.sh at nic.sh. The website is on the server www.myskoob.com/postish. Unfortunately, nic.sh does not support frames, i.e. that the domain stays posti.sh as it forwards to www.myskoob.com/postish - so I thought about a URL rewrite on the server. Unfortunately I have no idea how rewriting works - I am thankful for explanations - but I would also like to ask whether this is generally possible. What I need is: The server needs to recognize that the folder postish is accessed Depending on the file that is opened, it needs to rewrite the url to www.posti.sh/<-according filename here- Also, the server needs to understand that a link to www.posti.sh/about.php links to www.myskoob.com/postish/about.php and likewise for other files - at the moment, when I type in posti.sh/about.php it redirects to http://www.myskoob.com/postishabout.php, which does not exist All this should be possible irrespective of whether the url contains a "www" at the beginning or not A plus but not necessary would be that it does not display the .php extensions Would that generally be possible? If not, what would be the alternatives? If anyone knows how to do it, any code and/or way to do it would be much appreciated!
