• Eloqua Experience 2013: Mystique, Modern Marketing and Masterful Engagement

  - by Mike Stiles

  The following is a guest post from Erick Mott, a social business leader at Oracle Eloqua. There’s a growing gap between 20th century marketing and a modern marketing way of doing business. I can’t think of a better example of modern marketing in action than what more than 2,000 people experienced in San Francisco at #EE13; customer-obsession, multichannel content, and real-time engagement all coming together at one extraordinary event. This was my first Eloqua Experience as a new Oracle Eloqua employee. In weeks prior, I heard about the mystique but didn’t know what to expect. What I’ve come to understand with more clarity is everything we do revolves around customer success, and we operate and educate at all times with these five tenets in mind: 1. Targeting: Really Know Your Buyer 2. Engagement: Create a 1:1 Relationship 3. Conversion: Visualize Guided Thinking 4. Analysis: Learn What’s Working 5. Marketing Technology: Enable and Extend the Cloud Product News from Eloqua Experience 2013 We made some announcements that John Stetic, VP of Products, Oracle Eloqua covers in this brief ‘Modern Marketing Minute’ video recorded after Wednesday’s keynote; summarized below, too: Oracle Eloqua AdFocus: While understanding the impact of a specific marketing channel was formerly relegated to marketers’ wish lists, the channels we now focus on are digital, social, and mobile. AdFocus gives marketers a single platform to dynamically create, manage and measure display ads alongside owned and earned media. AdFocus enables marketers to target only key accounts or prospects you want to reach with display ads, as well as provide creative content or personalized ad copy based on their persona and activities. Oracle Eloqua Profiler: The details of what we now know about customers have expanded into a universal customer profile, which can be used to create highly targeted segments. Marketers now can take data that’s not even stored in Eloqua to help targeted and score prospects for a complete, multichannel view of the customer. Profiler gives sales reps one, detailed view of the prospect to extend views beyond Oracle Eloqua asset activity (emails, forms, page views) to any external assets stored in Oracle Eloqua. Marketing Resource Management: New capabilities create more secure and controlled access to marketing resources and data. New integrations provide greater insight into campaign resources and management through a central marketing calendar and simplify resource management. Integrated Sales and Marketing Funnel: An integrated sales and marketing funnel view gives marketing and sales users, cross-functional teams, and executive management a consistent and clear view of pipeline performance. It also quickly provides users with historical metrics across different time spans and conditions. Eloqua AppCloud: More than 20 new AppCloud partners have been added to the community, which now includes 100+ apps. Eloqua AppCloud now provides modern marketers with an even broader range of marketing applications that help expand and enrich sales and marketing efforts; easily accessible in the Topliners Community. Social Capabilities: Recent integration between Oracle Eloqua and Oracle Social Relationship Management (SRM) deliver a comprehensive, scalable and integrated modern marketing solution. New capabilities include better tracking of social activities for a more complete customer profile. Engage Facebook custom audiences with AdFocus to deliver ads and meaningful experiences through trusted social networks. Biggest and Best Eloqua Experience. There’s a lot of talk in the industry about the Marketing Cloud. At Oracle Eloqua, we have been on a mission of delivering the most advanced and integrated modern marketing technology on the planet. It’s not just a concept but reality with proven execution, as seen first-hand this week in San Francisco. In this video, Kevin Akeroyd, SVP of Oracle Eloqua, provides some highlights of what made this year’s Eloqua Experience, exceptional, including Steve Woods’ presentation about the journey of modern marketers and Andrea Ward’s conversation with Vince Gilligan, creator of the Breaking Bad television series. The 2013 Markie Awards The Oracle Eloqua Marketing Cloud was best exemplified for me as 19 Markies were awarded to customers for their exceptional creativity and results as modern marketers. Wow, what a night to remember with so many committed and talented people working to create an extraordinary experience! To learn more about how to become a modern marketer, check out these resources. We look forward to seeing you next year at Eloqua Experience. More on Erick: 20 years experience at Oracle, Ektron, Sitecore, Lyris, Habeas, Nokia, creatorbase, Mark Monitor, Cisco Systems, GlobalFluency, Sun Microsystems, Philips NV, Elm Products and CBS TV.

• 4 Key Ingredients for the Cloud

  - by Kellsey Ruppel

  It's a short week here with the US Thanksgiving Holiday. So, before we put on our stretch pants and get ready to belly up to the dinner table for turkey, stuffing and mashed potatoes, let's spend a little time this week talking about the Cloud (kind of like the feathery whipped goodness that tops the infamous Thanksgiving pumpkin pie!) But before we dive into the Cloud, let's do a side by side comparison of the key ingredients for each. Cloud Whipped Cream  Application Integration  1 cup heavy cream  Security  1/4 cup sugar  Virtual I/O  1 teaspoon vanilla  Storage  Chilled Bowl It’s no secret that millions of people are connected to the Internet. And it also probably doesn’t come as a surprise that a lot of those people are connected on social networking sites.  Social networks have become an excellent platform for sharing and communication that reflects real world relationships and they play a major part in the everyday lives of many people. Facebook, Twitter, Pinterest, LinkedIn, Google+ and hundreds of others have transformed the way we interact and communicate with one another.Social networks are becoming more than just an online gathering of friends. They are becoming a destination for ideation, e-commerce, and marketing. But it doesn’t just stop there. Some organizations are utilizing social networks internally, integrated with their business applications and processes and the possibility of social media and cloud integration is compelling. Forrester alone estimates enterprise cloud computing to grow to over $240 billion by 2020. It’s hard to find any current IT project today that is NOT considering cloud-based deployments. Security and quality of service concerns are no longer at the forefront; rather, it’s about focusing on the right mix of capabilities for the business. Cloud vs. On-Premise? Policies & governance models? Social in the cloud? Cloud’s increasing sophistication, security in applications, mobility, transaction processing and social capabilities make it an attractive way to manage information. And Oracle offers all of this through the Oracle Cloud and Oracle Social Network. Oracle Social Network is a secure private network that provides a broad range of social tools designed to capture and preserve information flowing between people, enterprise applications, and business processes. By connecting you with your most critical applications, Oracle Social Network provides contextual, real-time communication within and across enterprises. With Oracle Social Network, you and your teams have the tools you need to collaborate quickly and efficiently, while leveraging the organization’s collective expertise to make informed decisions and drive business forward. Oracle Social Network is available as part of a portfolio of application and platform services within the Oracle Cloud. Oracle Cloud offers self-service business applications delivered on an integrated development and deployment platform with tools to rapidly extend and create new services. Oracle Social Network is pre-integrated with the Fusion CRM Cloud Service and the Fusion HCM Cloud Service within the Oracle Cloud. If you are looking for something to watch as you veg on the couch in a post-turkey dinner hangover, you might consider watching these how-to videos! And yes, it is perfectly ok to have that 2nd piece of pie

• Asynchrony in C# 5 (Part II)

  - by javarg

  This article is a continuation of the series of asynchronous features included in the new Async CTP preview for next versions of C# and VB. Check out Part I for more information. So, let’s continue with TPL Dataflow: Asynchronous functions TPL Dataflow Task based asynchronous Pattern Part II: TPL Dataflow Definition (by quote of Async CTP doc): “TPL Dataflow (TDF) is a new .NET library for building concurrent applications. It promotes actor/agent-oriented designs through primitives for in-process message passing, dataflow, and pipelining. TDF builds upon the APIs and scheduling infrastructure provided by the Task Parallel Library (TPL) in .NET 4, and integrates with the language support for asynchrony provided by C#, Visual Basic, and F#.” This means: data manipulation processed asynchronously. “TPL Dataflow is focused on providing building blocks for message passing and parallelizing CPU- and I/O-intensive applications”. Data manipulation is another hot area when designing asynchronous and parallel applications: how do you sync data access in a parallel environment? how do you avoid concurrency issues? how do you notify when data is available? how do you control how much data is waiting to be consumed? etc.  Dataflow Blocks TDF provides data and action processing blocks. Imagine having preconfigured data processing pipelines to choose from, depending on the type of behavior you want. The most basic block is the BufferBlock<T>, which provides an storage for some kind of data (instances of <T>). So, let’s review data processing blocks available. Blocks a categorized into three groups: Buffering Blocks Executor Blocks Joining Blocks Think of them as electronic circuitry components :).. 1. BufferBlock<T>: it is a FIFO (First in First Out) queue. You can Post data to it and then Receive it synchronously or asynchronously. It synchronizes data consumption for only one receiver at a time (you can have many receivers but only one will actually process it). 2. BroadcastBlock<T>: same FIFO queue for messages (instances of <T>) but link the receiving event to all consumers (it makes the data available for consumption to N number of consumers). The developer can provide a function to make a copy of the data if necessary. 3. WriteOnceBlock<T>: it stores only one value and once it’s been set, it can never be replaced or overwritten again (immutable after being set). As with BroadcastBlock<T>, all consumers can obtain a copy of the value. 4. ActionBlock<TInput>: this executor block allows us to define an operation to be executed when posting data to the queue. Thus, we must pass in a delegate/lambda when creating the block. Posting data will result in an execution of the delegate for each data in the queue. You could also specify how many parallel executions to allow (degree of parallelism). 5. TransformBlock<TInput, TOutput>: this is an executor block designed to transform each input, that is way it defines an output parameter. It ensures messages are processed and delivered in order. 6. TransformManyBlock<TInput, TOutput>: similar to TransformBlock but produces one or more outputs from each input. 7. BatchBlock<T>: combines N single items into one batch item (it buffers and batches inputs). 8. JoinBlock<T1, T2, …>: it generates tuples from all inputs (it aggregates inputs). Inputs could be of any type you want (T1, T2, etc.). 9. BatchJoinBlock<T1, T2, …>: aggregates tuples of collections. It generates collections for each type of input and then creates a tuple to contain each collection (Tuple<IList<T1>, IList<T2>>). Next time I will show some examples of usage for each TDF block. * Images taken from Microsoft’s Async CTP documentation.

• PHP-FPM stops responding and dies [migrated]

  - by user12361

  I'm running Drupal 6 with Nginx 1.5.1 and PHP-FPM (PHP 5.3.26) on a 1GB single core VPS with 3GB of swap space on SSD storage. I just switched from shared hosting to this unmanaged VPS because my site was getting too heavy, so I'm still learning the ropes. I have moderately high traffic, I don't really monitor it closely but Google Adsense usually record close to 30K page views/day. I usually have 50 to 80 authenticated users logged in and a few hundred more anonymous users hitting the Boost static HTML cache at any given moment. The problem I'm having is that PHP-FPM frequently stops responding, resulting in Nginx 502 or 504 errors. I swear I have read every page on the internet about this issue, which seems fairly common, and I've tried endless combinations of configurations, and I can't find a good solution. After restarting Nginx and PHP-FPM, the site runs really fast for a while, and then without warning it simply stops responding. I get a white screen while the browser waits on the server, and after about 30 seconds to a minute it throws an Nginx 502 or 504 error. Sometimes it runs well for 2 minutes, sometimes 5 minutes, sometimes 5 hours, but it always ends up hanging. When I find the server in this state, there is still plenty of free memory (500MB or more) and no major CPU usage, the control and worker PHP-FPM processes are still present, and the server is still pingable and usable via SSH. A reload of PHP-FPM via the init script revives it again. The hangups don't seem to correspond to the amount of traffic, because I observed this behavior consistently when I was testing this configuration on a development VPS with no traffic at all. I've been constantly tweaking the settings, but I can't definitively eliminate the problem. I set Nginx workers to just 1. In the PHP-FPM config I have tried all three of the process managers. "Dynamic" is definitely the least reliable, consistently hanging up after only a few minutes. "Static" also has been unreliable and unpredictable. The least buggy has been "ondemand", but even that is failing me, sometimes after as much as 12 to 24 hours. But I can't leave the server unattended because PHP-FPM dies and never comes back on its own. I tried adjusting the pm.max_children value from as low as 3 to as high as 50, doesn't make a lot of difference, but I currently have it at 10. Same thing for the spare servers values. I also have set pm.max_requests anywhere from 30 to unlimited, and it doesn't seem to make a difference. According to the logs, the PHP-FPM processes are not exiting with SIGSEGV or SIGBUS, but rather with SIGTERM. I get a lot of lines like: WARNING: [pool www] child 3739, script '/var/www/drupal6/index.php' (request: "GET /index.php") execution timed out (38.739494 sec), terminating and: WARNING: [pool www] child 3738 exited on signal 15 (SIGTERM) after 50.004380 seconds from start I actually found several articles that recommend doing a graceful reload of PHP-FPM via cron every few minutes or hours to circumvent this issue. So that's what I did, "/etc/init.d/php-fpm reload" every 5 minutes. So far, it's keeping the lights on. But it feels like a dreadful hack. Is PHP-FPM really that unreliable? Is there anything else I can do? Thanks a lot!

• Modernizr Rocks HTML5

  - by Laila

  HTML5 is a moving target.  At the moment, we don't know what will be in future versions.  In most circumstances, this really matters to the developer. When you're using Adobe Air, you can be reasonably sure what works, what is there, and what isn't, since you have a version of the browser built-in. With Metro, you can assume that you're going to be using at least IE 10.   If, however,  you are using HTML5 in a web application, then you are going to rely heavily on Feature Detection.  Feature-Detection is a collection of techniques that tell you, via JavaScript, whether the current browser has this feature natively implemented or not Feature Detection isn't just there for the esoteric stuff such as  Geo-location,  progress bars,  <canvas> support,  the new <input> types, Audio, Video, web workers or storage, but is required even for semantic markup, since old browsers make a pigs ear out of rendering this.  Feature detection can't rely just on reading the browser version and inferring from that what works. Instead, you must use JavaScript to check that an HTML5 feature is there before using it.  The problem with relying on the user-agent is that it takes a lot of historical data  to work out what version does what, and, anyway, the user-agent can be, and sometimes is, spoofed. The open-source library Modernizr  is just about the most essential  JavaScript library for anyone using HTML5, because it provides APIs to test for most of the CSS3 and HTML5 features before you use them, and is intelligent enough to alter semantic markup into 'legacy' 'markup  using shims  on page-load  for old browsers. It also allows you to check what video Codecs are installed for playing video. It also provides media queries  and conditional resource-loading (formerly YepNope.js.).  Generally, Modernizr gives you the choice of what you do about browsers that don't support the feature that you want. Often, the best choice is graceful degradation, but the resource-loading feature allows you to dynamically load JavaScript Shims to replace the standard API for missing or defective HTML5 functionality, called 'PolyFills'.  As the Modernizr site says 'Yes, not only can you use HTML5 today, but you can use it in the past, too!' The evolutionary progress of HTML5  requires a more defensive style of JavaScript programming where the programmer adopts a mindset of fearing the worst ( IE 6)  rather than assuming the best, whilst exploiting as many of the new HTML features as possible for the requirements of the site or HTML application.  Why would anyone want the distraction of developing their own techniques to do this when  Modernizr exists to do this for you?

• Integrating Amazon S3 in Java via NetBeans IDE

  - by Geertjan

  To continue from yesterday, let's set up a scenario that enables us to make use of this drag/drop service in NetBeans IDE: The above service is applicable to Amazon S3, an Amazon storage provider that is typically used to store large binary files. In Amazon S3, every object stored is contained in a bucket. Buckets partition the namespace of objects stored in Amazon S3. More on buckets here. Let's use the tools in NetBeans IDE to create a Java application that accesses our Amazon S3 buckets. Create a Java application named "AmazonBuckets" with a main class named "AmazonBuckets". Open the main class and then drag the above service into the main method of the class. Now, NetBeans IDE will create all the other classes and the properties file that you see in the screenshot below. The first thing to do is to open the properties file above and enter the access key and secret: access_key=SOMETHINGsecret=SOMETHINGELSE Now you're all set up. Make sure to, of course, actually have some buckets available: Then rewrite the Java class to parse the XML that is returned via the generated code: package amazonbuckets;import java.io.ByteArrayInputStream;import java.io.IOException;import javax.xml.parsers.DocumentBuilder;import javax.xml.parsers.DocumentBuilderFactory;import javax.xml.parsers.ParserConfigurationException;import org.netbeans.saas.amazon.AmazonS3Service;import org.netbeans.saas.RestResponse;import org.w3c.dom.DOMException;import org.w3c.dom.Document;import org.w3c.dom.Node;import org.w3c.dom.NodeList;import org.xml.sax.InputSource;import org.xml.sax.SAXException;public class AmazonBuckets {    public static void main(String[] args) {        try {            RestResponse result = AmazonS3Service.getBuckets();            String dataAsString = result.getDataAsString();            DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();            DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();            Document doc = dBuilder.parse(                    new InputSource(new ByteArrayInputStream(dataAsString.getBytes("utf-8"))));            NodeList bucketList = doc.getElementsByTagName("Bucket");            for (int i = 0; i < bucketList.getLength(); i++) {                Node node = bucketList.item(i);                System.out.println("Bucket Name: " + node.getFirstChild().getTextContent());            }        } catch (IOException | ParserConfigurationException | SAXException | DOMException ex) {        }    }}That's all. This is simpler to setup than the scenario described yesterday. Also notice that there are other Amazon S3 services you can interact with from your Java code, again after generating a heap of code after drag/drop into a Java source file: I tried the above, e.g., I created a new Amazon S3 bucket after dragging "createBucket", adding my credentials in the properties file, and then running the code that had been created. I.e., without adding a single line of code I was able to programmatically create new buckets. The above outlines a handy set of tools and techniques to use if you want to let your users store and access data in Amazon S3 buckets directly from the application you've created for them.

• Multitenancy in SQL Azure

  - by cibrax

  If you are building a SaaS application in Windows Azure that relies on SQL Azure, it’s probably that you will need to support multiple tenants at database level. This is short overview of the different approaches you can use for support that scenario, A different database per tenant A new database is created and assigned when a tenant is provisioned. Pros Complete isolation between tenants. All the data for a tenant lives in a database only he can access. Cons It’s not cost effective. SQL Azure databases are not cheap, and the minimum size for a database is 1GB.  You might be paying for storage that you don’t really use. A different connection pool is required per database. Updates must be replicated across all the databases You need multiple backup strategies across all the databases Multiple schemas in a database shared by all the tenants A single database is shared among all the tenants, but every tenant is assigned to a different schema and database user. Pros You only pay for a single database. Data is isolated at database level. If the credentials for one tenant is compromised, the rest of the data for the other tenants is not. Cons You need to replicate all the database objects in every schema, so the number of objects can increase indefinitely. Updates must be replicated across all the schemas. The connection pool for the database must maintain a different connection per tenant (or set of credentials) A different user is required per tenant, which is stored at server level. You have to backup that user independently. Centralizing the database access with store procedures in a database shared by all the tenants A single database is shared among all the tenants, but nobody can read the data directly from the tables. All the data operations are performed through store procedures that centralize the access to the tenant data. The store procedures contain some logic to map the database user to an specific tenant. Pros You only pay for a single database. You only have a set of objects to maintain and backup. Cons There is no real isolation. All the data for the different tenants is shared in the same tables. You can not use traditional ORM like EF code first for consuming the data. A different user is required per tenant, which is stored at server level. You have to backup that user independently. SQL Federations A single database is shared among all the tenants, but a different federation is used per tenant. A federation in few words, it’s a mechanism for horizontal scaling in SQL Azure, which basically uses the idea of logical partitions to distribute data based on certain criteria. Pros You only have a single database with multiple federations. You can use filtering in the connections to pick the right federation, so any ORM could be used to consume the data. Cons There is no real isolation at that database level. The isolation is enforced programmatically with federations.

• Add a row to UITableView for adding new item?

  - by David.Chu.ca

  In order to provide UI for user to add new items to my table view, I would like to add a new row in my table at a specified location (last row for example) when the view is in edit mode (I have a edit button on the view's navigation bar right side). This new row will have a add button indicator on the left side and disclosure accessory arrow on the right. When the view is not in edit mode, this add row should not be displayed. I am not sure if I should overwrite: - (void)setEditing:(BOOL)editing animated:(BOOL)animated{...} where I call the UITableView's method: insertRowsAtIndexPaths:(NSArray *)indexPaths withRowAnimation: (UITableViewRowAnimation)animation to insert a new row? My understanding is that this call may add a new row into the table view. The table view's data source is from CoreData storage. Not sure this may cause inconsistent numbers of data in the data store and table view? If it is OK and I have to manage rows in the table view, how can I add left add indicator and left disclosure arrow to the new row? Another question is that if I can do it to insert a new row as Add row, should I remove it when the table view not in edit mode? Just want to know if I am on the right track.

• Sending formatted Lotus Notes rich text email from Excel VBA

  I have little Lotus Script or Notes/Domino knowledge but I have a procedure, copied from somewhere a long time ago, that allows me to email through Notes from VBA. I normally only use this for internal notifications where the formatting hasn't really mattered. I now want to use this to send external emails to a client, and corporate types would rather the email complied with our style guide (a sans-serif typeface basically). I was about to tell them that the code only works with plain text, but then I noticed that the routine does reference some sort of CREATERICHTEXTITEM object. Does this mean I could apply some sort of formatting to the body text string after it has been passed to the mail routine? As well as upholding our precious brand values, this would be quite handy to me for highlighting certain passages in the email. I've had a dig about the 'net to see if this code could be adapted, but being unfamiliar with Notes' object model, and the fact that online Notes resources seem to mirror the application's own obtuseness, meant I didn't get very far. The code: Sub sendEmail(EmailSubject As String, EMailSendTo As String, EMailBody As String, MailServer as String) Dim objNotesSession As Object Dim objNotesMailFile As Object Dim objNotesDocument As Object Dim objNotesField As Object Dim sendmail As Boolean 'added for integration into reporting tool Dim dbString As String dbString = "mail\" & Application.UserName & ".nsf" On Error GoTo SendMailError 'Establish Connection to Notes Set objNotesSession = CreateObject("Notes.NotesSession") On Error Resume Next 'Establish Connection to Mail File Set objNotesMailFile = objNotesSession.GETDATABASE(MailServer, dbString) 'Open Mail objNotesMailFile.OPENMAIL On Error GoTo 0 'Create New Memo Set objNotesDocument = objNotesMailFile.createdocument Dim oWorkSpace As Object, oUIdoc As Object Set oWorkSpace = CreateObject("Notes.NotesUIWorkspace") Set oUIdoc = oWorkSpace.CurrentDocument 'Create 'Subject Field' Set objNotesField = objNotesDocument.APPENDITEMVALUE("Subject", EmailSubject) 'Create 'Send To' Field Set objNotesField = objNotesDocument.APPENDITEMVALUE("SendTo", EMailSendTo) 'Create 'Copy To' Field Set objNotesField = objNotesDocument.APPENDITEMVALUE("CopyTo", EMailCCTo) 'Create 'Blind Copy To' Field Set objNotesField = objNotesDocument.APPENDITEMVALUE("BlindCopyTo", EMailBCCTo) 'Create 'Body' of memo Set objNotesField = objNotesDocument.CREATERICHTEXTITEM("Body") With objNotesField .APPENDTEXT emailBody .ADDNEWLINE 1 End With 'Send the e-mail Call objNotesDocument.Save(True, False, False) objNotesDocument.SaveMessageOnSend = True 'objNotesDocument.Save objNotesDocument.Send (0) 'Release storage Set objNotesSession = Nothing Set objNotesMailFile = Nothing Set objNotesDocument = Nothing Set objNotesField = Nothing 'Set return code sendmail = True Exit Sub SendMailError: Dim Msg Msg = "Error # " & Str(Err.Number) & " was generated by " _ & Err.Source & Chr(13) & Err.Description MsgBox Msg, , "Error", Err.HelpFile, Err.HelpContext sendmail = False End Sub

• The null value cannot be assigned to a member with type System.Int64 which is a non-nullable value t

  - by BritishDeveloper

  I'm getting the following error in my MVC2 app using Linq to SQL (I am new to both). I am connected to an actual SQL server not weird mdf: System.InvalidOperationException The null value cannot be assigned to a member with type System.Int64 which is a non-nullable value type My SQL table has a column called MessageID. It is BigInt type and has a primary key, NOT NULL and an IDENTITY 1 1, no Default In my dbml designer it has the following declaration for this field: [global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_MessageId", AutoSync=AutoSync.OnInsert, DbType="BigInt NOT NULL IDENTITY", IsPrimaryKey=true, IsDbGenerated=true)] public long MessageId { get { return this._MessageId; } set { if ((this._MessageId != value)) { this.OnMessageIdChanging(value); this.SendPropertyChanging(); this._MessageId = value; this.SendPropertyChanged("MessageId"); this.OnMessageIdChanged(); } } } It keeps telling me that null cannot be assigned - I'm not passing through null! It's a long - it can't even be null! Am I doing something stupid? I can't find a solution anywhere! I made this work by changing the type of this property to Nullable<long> but surely this can't be right? Update: I am using InsertOnSubmit. Simplified code: public ActionResult Create(Message message) { if (ModelState.IsValid) { var db = new MessagingDataContext(); db.Messages.InsertOnSubmit(message); db.SubmitChanges(); //line 93 (where it breaks) } } breaks on SubmitChanges() with the error at the top of this question.

• "cloud architecture" concepts in a system architecture diagrams

  - by markus

  If you design a distributed application for easy scale-out, or you just want to make use of any of the new “cloud computing” offerings by Amazon, Google or Microsoft, there are some typical concepts or components you usually end up using: distributed blob storage (aka S3) asynchronous, durable message queues (aka SQS) non-Relational-/non-transactional databases (like SimpleDB, Google BigTable, Azure SQL Services) distributed background worker pool load-balanced, edge-service processes handling user requests (often virtualized) distributed caches (like memcached) CDN (content delivery network like Akamai) Now when it comes to design and sketch an architecture that makes use of such patterns, are there any commonly used symbols I could use? Or even a download with some cool Visio stencils? :) It doesn’t have to be a formal system like UML but I think it would be great if there were symbols that everyone knows and understands, like we have commonly used shapes for databases or a documents, for example. I think it would be important to not mix it up with traditional concepts like a normal file system (local or network server/SAN), or a relational database. Simply speaking, I want to be able to draw some conclusions about an application’s scalability or data consistency issues by just looking at the system architecture overview diagram. Update: Thank you very much for your answers. I like the idea of putting a small "cloud symbol" on the traditional symbols. However I leave this thread open just in case someone will find specific symbols (maybe in a book or so) - or uploaded some pimped up Visio stencils ;)

• File path for J2ME FileConnection?

  - by Kilnr

  Hi, I'm writing a MIDlet which needs to write file. I'm using FileConnection from JSR-75 to accomplish this. The intention is to have this MIDlet runnning on as much devices as possible (all MIDP 2.0 devices with JSR-75 support, ideally). On several emulators and an HTC Touch Pro2, I can perfectly use the following code to get the root of the filesystem: Enumeration drives = FileSystemRegistry.listRoots(); String root = (String) drives.nextElement(); String path = "file:///" + root; However, on a Nokia S60 5th edition emulator, trying to open a FileConnection to this path throws a java.lang.SecurityException. Apparently S60 devices do not allow connections to the root of the filesystem. I realise I can use something like System.getProperty("fileconn.dir.photos"), but that isn't supported on all devices either. So, my actual question: what is the best approach to get a path to create a FileConnection with, that allows for maximum portability? Thanks. Edit: I suppose I could iterate over all the roots in the Enumeration, and check for a writable one, but that's hardly optimal for two reasons. First, there aren't necessarily any writable roots. Second, this could be the phone memory or a memory card, so the storage method wouldn't be consistent across devices, which is rather ugly.

• Hive Based Registry in Flash

  - by Psychic

  To start with I'll say I've read the post here and I'm still having trouble. I'm trying to create a CE6 image with a hive-based registry that actually stores results through a reboot. I've ticked the hive settings in the catalog items. In common.reg, I've set the location of the hive ([HKEY_LOCAL_MACHINE\init\BootVars] "SystemHive") to "Hard Drive\Registry" (Note: the flash shows up as a device called "Hard Drive") In common.reg, I've set "Flags"=dword:3 in the same place to get the device manager loaded along with the storage manager I've verified that these settings are wrapped in "; HIVE BOOT SECTION" This is where it starts to fall over. It all compiles fine, but on the target system, when it boots, I get: A directory, called "Hard Disk" where a registry is put A device, name called "Hard Disk2" where the permanent flash is Any changes made to the registry are lost on a reboot What am I still missing? Why is the registry not being stored on the flash? Strangly, if I create a random file/directory in the registry directory, it is still there after a reboot, so even though this directory isn't on the other partition (where I tried to put it), it does appear to be permanent. If it is permanent, why don't registry settings save (ie Ethernet adapter IP addresses?) I'm not using any specific profiles, so I'm at a loss as to what the last step is to make this hive registry a permanent store.

• Mapping and metadata information could not be found for EntityType Exception

  - by dcompiled

  I am trying out ASP.NET MVC Framework 2 with the Microsoft Entity Framework and when I try and save new records I get this error: Mapping and metadata information could not be found for EntityType 'WebUI.Controllers.PersonViewModel' My Entity Framework container stores records of type Person and my view is strongly typed with class PersonViewModel which derives from Person. Records would save properly until I tried to use the derived view model class. Can anyone explain why the metadata class doesnt work when I derive my view model? I want to be able to use a strongly typed model and also use data annotations (metadata) without resorting to mixing my storage logic (EF classes) and presentation logic (views). // Rest of the Person class is autogenerated by the EF [MetadataType(typeof(Person.Metadata))] public partial class Person { public sealed class Metadata { [DisplayName("First Name")] [Required(ErrorMessage = "Field [First Name] is required")] public object FirstName { get; set; } [DisplayName("Middle Name")] public object MiddleName { get; set; } [DisplayName("Last Name")] [Required(ErrorMessage = "Field [Last Name] is required")] public object LastName { get; set; } } } // From the View (PersonCreate.aspx) <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<WebUI.Controllers.PersonViewModel>" %> // From PersonController.cs public class PersonViewModel : Person { public List<SelectListItem> TitleList { get; set; } } // end class PersonViewModel

• PHP MYSQL FPDF retrieving pdf string stored as blob.

  - by jj.amonit

  Using the above technologies, I want to create a PDF, store it in my db, and email it. All with the click of one button. I also want to call it up and have it be able to display with a hyperlink. I am very new to FPDF. Therefore, I am trying to start off very slowly. I began with this link stackoverflow Q I put both parts of his code into the same page and tried with separate pages. I made the suggested changes/additions and even did a line by line comparison. I still get the message, "format error: not a PDF or corrupted" If I just $pdf-Output(); I get the pdf to display. It's either the way the string is being Output, or it's the header() function. It's not the storage method, unless my column setup is incorrect. BUt a blob is a blob, right? If you want, I can upload the sanitized code. Just let me know what would help answer this. Thanks JJ

• Using db4o with multiple application instances under medium trust

  - by Anders Fjeldstad

  I recently stumbled over the object database engine db4o which I think looks really interesting. I would like to use it in an ASP.NET MVC application that will be deployed to a shared hosting environment under medium trust. Because of the trust level, I'm restricted to using db4o in embedded/in-process mode. That in itself should be no problem, but the hosting provider also transparently runs each web application in multiple (load-balanced) server instances with shared storage, which I would say is normally a very nice feature for a $10/month hoster. However, since an instance of a db4o server with write access (whether in-process or networked) locks the underlying database file, having multiple instances of the application using the same file won't work (or at least I can't see how it would). So the question is: is it possible to use db4o in this specific environment? I have considered letting each application have its own database which is synchronized with a master database using replication (dRS), but that approach will most likely end up with very frequent bi-directional replication (read master changes at beginning of each request, write to master after each change) which I don't think will be very efficient. Summary of the web application/environment characteristics: Read-intensive (but not entirely read-only) Some delay (a few seconds) is acceptible between the time that a change is made and the time when the change shows up in all the application instances' data Must run in medium trust No guarantee that the load-balancer uses "sticky sessions" All suggestions are much appreciated!

• Does the WMI event Win32_VolumeChangeEvent work on Windows XP

  - by Christian Rodemeyer

  I'm trying to use the following c# code to detect the attached/removed event of usb mass storage devices. I'm using the Win32_VolumeChangeEvent. // Initialize an event watcher and subscribe to events that match this query var _watcher = new ManagementEventWatcher("select * from Win32_VolumeChangeEvent"); _watcher.EventArrived += OnDeviceChanged; _watcher.Start(); void OnDeviceChanged(object sender, EventArrivedEventArgs args) { Console.WriteLine(args.NewEvent.GetText(TextFormat.Mof)); } The problem is that this works fine on Vista but it doesn't work on XP at all (no events received). The Microsoft documentation says that this should work (http://msdn.microsoft.com/en-us/library/aa394516(VS.85).aspx). I googled for this quite a while and found other that have this problem too. But I also found a couple of articles which claim that this kind of query (mostly in vbscript) works with XP. But I cannot find some offical information from microsoft for this issue and I can't believe that Microsoft have overlooked this issue for three service packs. So my question is: has anybody used the Win32_VolumeChangeEvent with success on XP or can provide a link/explanation why it shouldn't work on XP?

• Draw to offscreen renderbuffer in OpenGL ES (iPhone)

  - by David Ensminger

  I'm trying to create an offscreen render buffer in OpenGL ES on the iPhone. I've created the buffer like this: glGenFramebuffersOES(1, &offscreenFramebuffer); glBindFramebufferOES(GL_FRAMEBUFFER_OES, offscreenFramebuffer); glGenRenderbuffersOES(1, &offscreenRenderbuffer); glBindRenderbufferOES(GL_RENDERBUFFER_OES, offscreenRenderbuffer); glFramebufferRenderbufferOES(GL_FRAMEBUFFER_OES, GL_COLOR_ATTACHMENT0_OES, GL_RENDERBUFFER_OES, offscreenRenderbuffer); But I'm confused on how to render the storage. Apple's documentation says to use the EAGLContext renderBufferStorage:fromDrawable: method, but this seems to only work for one render buffer (the main one being displayed). If I use the normal OpenGL function glRenderBufferStorageOES, then I can't seem to get it to display. Here's the code: // this is in the initialization section: glRenderbufferStorageOES(GL_RENDERBUFFER_OES, GL_RGB8_OES, backingWidth, backingHeight); // and this is when I'm trying to draw to it and display it: glBindFramebufferOES(GL_FRAMEBUFFER_OES, offscreenFramebuffer); GLfloat vc[] = { 0.0f, 0.0f, 0.0f, 10.0f, 10.0f, 10.0f, 0.0f, 0.0f, 0.0f, -10.0f, -10.0f, -10.0f, }; glLoadIdentity(); glEnableClientState(GL_VERTEX_ARRAY); glVertexPointer(3, GL_FLOAT, 0, vc); glDrawArrays(GL_LINES, 0, 4); glDisableClientState(GL_VERTEX_ARRAY); glBindRenderbufferOES(GL_RENDERBUFFER_OES, offscreenRenderbuffer); [context presentRenderbuffer:GL_RENDERBUFFER_OES]; Doing it this way, nothing is displayed on the screen. However, if I switch out the references to "offscreen...Buffer" to the buffers that were created with the renderBufferStorage method, it works fine. Any suggestions?

• LINQ-to-SQL: Could not find key member 'x' of key 'x' on type 'y'

  - by Austin Hyde

  I am trying to connect my application to a SQLite database with LINQ-to-SQL, and so far everything has worked fine. The only hitch was that the SQLite provider I am using does not support code generation (unless I was doing something wrong), so I manually coded the 4 tables in the DB. The solution builds properly, but will not run, giving me the error message Could not find key member 'ItemType_Id' of key 'ItemType_Id' on type 'Item'. The key may be wrong or the field or property on 'Item' has changed names. I have checked and double checked spellings and field names on the database and in the attribute mappings, but could not find any problems. The SQL for the table looks like this: CREATE TABLE [Items] ( [Id] integer PRIMARY KEY AUTOINCREMENT NOT NULL, [Name] text NOT NULL, [ItemType_Id] integer NOT NULL ); And my mapping code: [Table(Name="Items")] class Item { // [snip] [Column(Name = "Id", IsPrimaryKey=true, IsDbGenerated=true)] public int Id { get; set; } // [snip] [Column(Name="ItemType_Id")] public int ItemTypeId { get; set; } [Association(Storage = "_itemType", ThisKey = "ItemType_Id")] public ItemType ItemType { get { return _itemType.Entity; } set { _itemType.Entity = value; } } private EntityRef<ItemType> _itemType; // [snip] } This is really my first excursion into LINQ-to-SQL, and am learning as I go, but I cannot seem to get past this seeming simple problem. Why cannot LINQ see my association?

• Paperclip and Amazon S3 Issue

  - by Jimmy

  Hey everyone, I have a rails app running on Heroku. I am using paperclip for some simple image uploads for user avatars and some other things, I have S3 set as my backend and everything seems to be working fine except when trying to push to S3 I get the following error: The AWS Access Key Id you provided does not exist in our records. Thinking I mis-pasted my access key and secret key, I tried again, still no luck. Thinking maybe it was just a buggy key I deactivated it and generated a new one. Still no luck. Now for both keys I have used the S3 browser app on OS X and have been able to connect to each and view my current buckets and add/delete buckets. Is there something I should be looking out for? I have my application's S3 and paperclip setup like so development: bucket: (unique name) access_key_id: ENV['S3_KEY'] secret_access_key: ENV['S3_SECRET'] test: bucket: (unique name) access_key_id: ENV['S3_KEY'] secret_access_key: ENV['S3_SECRET'] production: bucket: (unique_name) access_key_id: ENV['S3_KEY'] secret_access_key: ENV['S3_SECRET'] has_attached_file :cover, :styles => { :thumb => "50x50" }, :storage => :s3, :s3_credentials => "#{RAILS_ROOT}/config/s3.yml", :path => ":class/:id/:style/:filename" Note: I just added the (unique name) bits, those aren't actually there--I have also verified bucket names, but I don't even think this is getting that far. I also have my heroku environment vars setup correctly and have them setup on dev

• Linq - how does it work??

  - by clarkeyboy

  Hey, I have just been looking into Linq with ASP.Net. It is very neat indeed. I was just wondering - how do all the classes get populated? I mean in ASP.Net, suppose you have a Linq file called Catalogue, and you then use a For loop to loop through Catalogue.Products and print each Product name. How do the details get stored? Does it just go through the Products table on page load and create another instance of class Product for each row, effectively copying an entire table into an array of class Product? If so, I think I have created a system very much like this, in the sense that there is a SiteContent module with an instance of each Manager class - for example there is UserManager, ProductManager, SettingManager and alike. UserManager contains an instance of the User class for each row in the Users table. They also contain methods such as Create, Update and Remove. These Managers and their "Items" are created on every page load. This just makes it nice and easy to access users, products, settings etc in every page as far as I, the developer, am concerned. Any any subsequent pages I need to create, I just need to reference SiteContent.UserManager to access a list of users, rather than executing a query from within that page (ie this method separates out data access from the workings of the page, in the same way as using code behind separates out the workings of the page from how the page is layed out). However the problem is that this technique seems rather slow. I mean it is effectively creating a database on every page load, taking data from another database. I have taken measures such as preventing, for example, the ProductManager from being created if it is not referenced on page load. Therefore it does not load data into storage when it is not needed. My question is basically whether my technique does the exact same thing as Linq, in the sense of duplicating data from tables into properties of classes.. Thanks in advance for any advice or answers about this. Regards, Richard Clarke

• Storing data on SD Card in Android

  Using the guide at Android Developers (http://developer.android.com/guide/topics/data/data-storage.html) I've tried to store some data to the SD-Card. This is my code: // Path to write files to String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Android/data/"+ctxt.getString(R.string.package_name)+"/files/"; String fname = "mytest.txt"; // Current state of the external media String extState = Environment.getExternalStorageState(); // External media can be written onto if (extState.equals(Environment.MEDIA_MOUNTED)) { try { // Make sure the path exists boolean exists = (new File(path)).exists(); if (!exists){ new File(path).mkdirs(); } // Open output stream FileOutputStream fOut = new FileOutputStream(path + fname); fOut.write("Test".getBytes()); // Close output stream fOut.flush(); fOut.close(); } catch (IOException ioe) { ioe.printStackTrace(); } When I create the new FileOutputStream I get a FileNotFound exception. I have also noticed that "mkdirs()" does not seem to create the directory. Can anyone tell me what I'm doing wrong? I'm testing on an AVD with a 2GB sd card and "hw.sdCard: yes", the File Explorer of DDMS in Eclipse tells me that the only directory on the sdcard is "LOST.DIR".

• Performance penalty of typecasting and boxing/unboxing types in C# when storing generic values

  - by kitsune

  I have a set-up similar to WPF's DependencyProperty and DependencyObject system. My properties however are generic. A BucketProperty has a static GlobalIndex (defined in BucketPropertyBase) which tracks all BucketProperties. A Bucket can have many BucketProperties of any type. A Bucket saves and gets the actual values of these BucketProperties... now my question is, how to deal with the storage of these values, and what is the penalty of using a typecasting when retrieving them? I currently use an array of BucketEntries that save the property values as simple objects. Is there any better way of saving and returning these values? Beneath is a simpliefied version: public class BucketProperty<T> : BucketPropertyBase { } public class Bucket { private BucketEntry[] _bucketEntries; public void SaveValue<T>(BucketProperty<T> property, T value) { SaveBucketEntry(property.GlobalIndex, value) } public T GetValue<T>(BucketProperty<T> property) { return (T)FindBucketEntry(property.GlobalIndex).Value; } } public class BucketEntry { private object _value; private uint _index; public BucketEntry(uint globalIndex, object value) { ... } }

• Eclipse RAP - Firefox doesn't forget session

  - by Fritz H

  We've got an Eclipse RAP application that's behaving a bit strangely in Firefox - two distinct problems. When you browse around, you can click on a button in one part of the system. This opens a popup window like so: IWorkbenchBrowserSupport bs; bs = PlatformUI.getWorkbench().getBrowserSupport(); int style = IWorkbenchBrowserSupport.AS_EXTERNAL; IWebBrowser b = bs.createBrowser(style, getRandomID(), "Hello world", ""); b.openURL(new URL(...)); where the URL is another servlet in the application. This servlet is in the same runtime, but has nothing to do with RAP - it takes a binary blob from in-memory storage and dumps it in the output stream. Problem 1: This causes the HTTP session to die in firefox, and shows the "session expired" RAP error page with a link to restart the session. Problem 2: Now, when you click on the link to restart the session, it shows the application's dialog again, but the session expired error is shown again the moment you do anything. This prevents the user from using the system again, unless Firefox is closed down completely and restarted. A quick peek with FireBug reveals that the JSESSIONID passed by Firefox does not change. Has anyone seen this before?
