  • Inside BackgroundWorker

    - by João Angelo
    The BackgroundWorker is a reusable component that can be used in different contexts, but sometimes with unexpected results. If you are like me, you have mostly used background workers while doing Windows Forms development due to the flexibility they offer for running a background task. They support cancellation and give events that signal progress updates and task completion. When used in Windows Forms, these events (ProgressChanged and RunWorkerCompleted) get executed back on the UI thread where you can freely access your form controls. However, the logic of the progress changed and worker completed events being invoked in the thread that started the background worker is not something you get directly from the BackgroundWorker, but instead from the fact that you are running in the context of Windows Forms. Take the following example that illustrates the use of a worker in three different scenarios: – Console Application or Windows Service; – Windows Forms; – WPF. using System; using System.ComponentModel; using System.Threading; using System.Windows.Forms; using System.Windows.Threading; class Program { static AutoResetEvent Synch = new AutoResetEvent(false); static void Main() { var bw1 = new BackgroundWorker(); var bw2 = new BackgroundWorker(); var bw3 = new BackgroundWorker(); Console.WriteLine("DEFAULT"); var unspecializedThread = new Thread(() => { OutputCaller(1); SynchronizationContext.SetSynchronizationContext( new SynchronizationContext()); bw1.DoWork += (sender, e) => OutputWork(1); bw1.RunWorkerCompleted += (sender, e) => OutputCompleted(1); // Uses default SynchronizationContext bw1.RunWorkerAsync(); }); unspecializedThread.IsBackground = true; unspecializedThread.Start(); Synch.WaitOne(); Console.WriteLine(); Console.WriteLine("WINDOWS FORMS"); var windowsFormsThread = new Thread(() => { OutputCaller(2); SynchronizationContext.SetSynchronizationContext( new WindowsFormsSynchronizationContext()); bw2.DoWork += (sender, e) => OutputWork(2); bw2.RunWorkerCompleted += (sender, e) => OutputCompleted(2); // Uses WindowsFormsSynchronizationContext bw2.RunWorkerAsync(); Application.Run(); }); windowsFormsThread.IsBackground = true; windowsFormsThread.SetApartmentState(ApartmentState.STA); windowsFormsThread.Start(); Synch.WaitOne(); Console.WriteLine(); Console.WriteLine("WPF"); var wpfThread = new Thread(() => { OutputCaller(3); SynchronizationContext.SetSynchronizationContext( new DispatcherSynchronizationContext()); bw3.DoWork += (sender, e) => OutputWork(3); bw3.RunWorkerCompleted += (sender, e) => OutputCompleted(3); // Uses DispatcherSynchronizationContext bw3.RunWorkerAsync(); Dispatcher.Run(); }); wpfThread.IsBackground = true; wpfThread.SetApartmentState(ApartmentState.STA); wpfThread.Start(); Synch.WaitOne(); } static void OutputCaller(int workerId) { Console.WriteLine( "bw{0}.{1} | Thread: {2} | IsThreadPool: {3}", workerId, "RunWorkerAsync".PadRight(18), Thread.CurrentThread.ManagedThreadId, Thread.CurrentThread.IsThreadPoolThread); } static void OutputWork(int workerId) { Console.WriteLine( "bw{0}.{1} | Thread: {2} | IsThreadPool: {3}", workerId, "DoWork".PadRight(18), Thread.CurrentThread.ManagedThreadId, Thread.CurrentThread.IsThreadPoolThread); } static void OutputCompleted(int workerId) { Console.WriteLine( "bw{0}.{1} | Thread: {2} | IsThreadPool: {3}", workerId, "RunWorkerCompleted".PadRight(18), Thread.CurrentThread.ManagedThreadId, Thread.CurrentThread.IsThreadPoolThread); Synch.Set(); } } Output: //DEFAULT //bw1.RunWorkerAsync | Thread: 3 | IsThreadPool: False //bw1.DoWork | Thread: 4 | IsThreadPool: True //bw1.RunWorkerCompleted | Thread: 5 | IsThreadPool: True //WINDOWS FORMS //bw2.RunWorkerAsync | Thread: 6 | IsThreadPool: False //bw2.DoWork | Thread: 5 | IsThreadPool: True //bw2.RunWorkerCompleted | Thread: 6 | IsThreadPool: False //WPF //bw3.RunWorkerAsync | Thread: 7 | IsThreadPool: False //bw3.DoWork | Thread: 5 | IsThreadPool: True //bw3.RunWorkerCompleted | Thread: 7 | IsThreadPool: False As you can see the output between the first and remaining scenarios is somewhat different. While in Windows Forms and WPF the worker completed event runs on the thread that called RunWorkerAsync, in the first scenario the same event runs on any thread available in the thread pool. Another scenario where you can get the first behavior, even when on Windows Forms or WPF, is if you chain the creation of background workers, that is, you create a second worker in the DoWork event handler of an already running worker. Since the DoWork executes in a thread from the pool the second worker will use the default synchronization context and the completed event will not run in the UI thread.

  • Wesquare (NL) helps major CG customer integrating Oracle Service Cloud (RightNow) with JDEdwards

    - by Richard Lefebvre
    Normal 0 false false false EN-US X-NONE X-NONE When this well known, Italy based, CG player claimed that they needed a new CRM tool, Oracle partner WeSquare had a precise idea of what would be required, knowing that the customer was using JDEdwards as an ERP: they immediately thoughts about a solution that would help synchronizing the customer’s back-end system with the new CRM interface. The customer asked for presentations from three companies, including Oracle, and eventually selected Oracle Service Cloud (RightNow) with Alfa Sistemi (Oracle Platinum Partner) as a System Integrator supported by Wesquare (Oracle Gold partner specialized in RightNow). Synchronizing an On Premises ERP with a new SaaS based CRM platform could be seen as an uphill task, but WeSquare was determined, during the presales cycle, to prove that they had the skills and the attitude to make the difference. So, they rolled up their sleeves and got to it: five days of relentless work, missed lunches, and hours of brainstorming showed its result in the form of a new interface that works fabulously well with the JDEdwards ERP back-end and was successfully pitched by Oracle to the end-customer to win the deal! WeSquare took the occasion to learn that they can integrate Oracle Service Cloud (RightNow) with practically every other solution that a customer may run. As part of the project, WeSquare was also involved in different add-on’s development with the aim of enriching Oracle Service Cloud’s functionality. WeSquare is based in The Netherlands with an in-shore practice supported by off-shore teams in India. WeSquare can integrate and synchronize any application with RightNow.

  • Best way to find freelance c# developer

    - by sturdytree
    I am a developer based in London developing a desktop WPF business application using c# (+ MVVM/DDD/Nhibernate/Unity/Postsharp...). I need to find someone to review my code to suggest improvements and then to write integration tests. This could potentially be an ongoing relationship, expanding into writing new features etc. It would suit an experienced developer with a strong interest in design principles and writing clean code, who can work part time. However, the developer would need to work at my home based office (although timing is flexible). Websites such as elance and odesk seem to tie you in, and I would prefer to pay a one off introduction fee and then deal with the developer direct. Stack exchange seems quite expensive but is a possibility if I don't find an alternative. So, are there any other websites I can try?

  • Advertising Campaign Bidding Network

    - by David
    I hope this is the correct stackexchange to post on. Seems to most relevant. I'm looking for more ways to monetize my site. I'm already using the usual Google Adsense, tradedoublers, ad networks, etc. What I want to know, is if anyone knows of a service/network out there (similar to tradedoubler), which allows you to accept (or bid) on campaigns (primarily CPM based). For example: I log in, I get a list of advertising campaigns that are available and the prices they are willing to pay or I can put a bid in with imp count and cpm rate. I'm looking for something ideally europe or UK based, but im open to others. Thanks!

  • New Procurement Report for Transportation Sourcing

    - by John Murphy
    Welcome to our fourth annual transportation procurement benchmark report. American Shipper, in partnership with the Council of Supply Chain Management Professionals (CSCMP) and the Retail Industry Leaders Association (RILA), surveyed roughly 275 transportation buyers and sellers on procurement practices, processes, technologies and results. Some key findings: • Manual, spreadsheet-based procurement processes remain the most prevalent among transportation buyers, with 42 percent of the total • Another 25 percent of respondents use a hybrid platform, which presumably means these buyers are using spreadsheets for at least one mode and/or geography • Only 23 percent of buyers are using a completely systems-based approach of some kind • Shippers were in a holding pattern with regards to investment in procurement systems the past year • Roughly three-quarters of survey respondents report that transportation spend has increased in 2012, although the pace has declined slightly from last year’s increases • Nearly every survey respondent purchases multiple modes of transportation • The number of respondents with plans to address technology to support the procurement process has increased in 2012. About one quarter of respondents who do not have a system report they have a budget for this investment in the next two years.

  • Harnessing Business Events for Predictive Decision Making - part 1 / 3

    - by Sanjeev Sharma
    Businesses have long relied on data mining to elicit patterns and forecast future demand and supply trends. Improvements in computing hardware, specifically storage and compute capacity, have significantly enhanced the ability to store and analyze mountains of data in ever shrinking time-frames. Nevertheless, the reality is that data growth is outpacing storage capacity by a factor of two and computing power is still very much bounded by Moore's Law, doubling only every 18 months.Faced with this data explosion, businesses are exploring means to develop human brain-like capabilities in their decision systems (including BI and Analytics) to make sense of the data storm, in other words business events, in real-time and respond pro-actively rather than re-actively. It is more like having a little bit of the right information just a little bit before hand than having all of the right information after the fact. To appreciate this thought better let's first understand the workings of the human brain.Neuroscience research has revealed that the human brain is predictive in nature and that talent is nothing more than exceptional predictive ability. The cerebral-cortex, part of the human brain responsible for cognition, thought, language etc., comprises of five layers. The lowest layer in the hierarchy is responsible for sensory perception i.e. discrete, detail-oriented tasks whereas each of the above layers increasingly focused on assembling higher-order conceptual models. Information flows both up and down the layered memory hierarchy. This allows the conceptual mental-models to be refined over-time through experience and repetition. Secondly, and more importantly, the top-layers are able to prime the lower layers to anticipate certain events based on the existing mental-models thereby giving the brain a predictive ability. In a way the human brain develops a "memory of the future", some sort of an anticipatory thinking which let's it predict based on occurrence of events in real-time. A higher order of predictive ability stems from being able to recognize the lack of certain events. For instance, it is one thing to recognize the beats in a music track and another to detect beats that were missed, which involves a higher order predictive ability.Existing decision systems analyze historical data to identify patterns and use statistical forecasting techniques to drive planning. They are similar to the human-brain in that they employ business rules very much like mental-models to chunk and classify information. However unlike the human brain existing decision systems are unable to evolve these rules automatically (AI still best suited for highly specific tasks) and  predict the future based on real-time business events. Mistake me not,  existing decision systems remain vital to driving long-term and broader business planning. For instance, a telco will still rely on BI and Analytics software to plan promotions and optimize inventory but tap into business events enabled predictive insight to identify specifically which customers are likely to churn and engage with them pro-actively. In the next post, i will depict the technology components that enable businesses to harness real-time events and drive predictive decision making.

  • What is considered to be a "modification" of sources under the BSD license?

    - by Den
    I have a question about the 3-clause BSD license based on it's Wiki description. It states: Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: ... What is understood by "modification"? Specifically I am interested whether any/all of the following is considered as such modification: 1) reading the original sources and then re-implementing; 2) reading the original sources, waiting for a year and then re-implementing something based on whatever you could remember; 3) direct and very significant "complete" refactoring of the original sources.

  • The Best How-To Geek Articles for June 2011

    - by Asian Angel
    June has been a busy month here at How-To Geek where we covered topics like cleaning keyboards, what to do when your e-mail has been compromised, creating high resolution Windows 7 icons, and more. Join us as we look back at the most popular articles from this past month. Note: Articles are listed as #10 through #1. What You Said: How Do You Keep Notes? Note taking applications have grown increasingly sophisticated. Historically, when people took notes on a computer they simply used the word processor or text editor installed on it and left it at that—mostly because there were few widely available alternatives. While many people still use simple txt files for their note taking needs an entire ecosystem of note taking apps exists now—thanks, in large part, to the rise of widespread internet access and easy synchronization.How To Encrypt Your Cloud-Based Drive with BoxcryptorHTG Explains: Photography with Film-Based CamerasHow to Clean Your Dirty Smartphone (Without Breaking Something)

  • Turnkey with LightSwitch

    - by Laila
    Microsoft has long wanted to find a replacement for Microsoft Access. The best attempt yet, which is due out in, or before, September is Visual Studio LightSwitch, with which it is said to be as 'easy as flipping a switch' to use Silverlight to create simple form-driven business applications. It is easy to get confused by the various initiatives from Microsoft. No, this isn't WebMatrix. There is no 'Razor', for this isn't meant for cute little ecommerce sites, but is designed to build simple database-applications of the card-box type. It is more clearly a .NET-based solution to the problem that every business seems to suffer from; the plethora of Access-based, and Excel-based 'private' and departmental database-applications. These are a nightmare for any IT department since they are often 'stealth' applications built by the business in the teeth of opposition from the IT Department zealots. As they are undocumented, it is scarily easy to bring a whole department into disarray by decommissioning a PC tucked under a desk somewhere. With LightSwitch, it is easy to re-write such applications in a standard, maintainable, way, using a SQL Server database, deployed somewhere reasonably safe such as Azure. Even Sharepoint or Windows Communication Foundation can be used as data sources. Oracle's ApEx has taken off remarkably well, and has shaken the perception that, for the business user, Oracle must remain a mystic force accessible only to the priests and acolytes. Microsoft, by comparison had only Access, which was first released in 1992, the year of the Madonna conical bustier. It looks just as dated. Microsoft badly needed an entirely new solution to the same business requirement that led to Access's and Foxpro's long-time popularity, but which had the same allure as ApEx. LightSwitch is sound in its ideas, and comfortingly conventional in its architecture. By giving an easy access to SQL Server databases, and providing a 'thumb and blanket' migration path to Access-heads, LightSwitch seems likely to offer a simple way of pulling more Microsoft users into the .NET community. If Microsoft puts its weight behind it, then it will give some glimmer of hope to the many Silverlight developers that Microsoft is capable of seeing through its .NET revolution.

  • JavaDay Taipei 2014 Trip Report

    - by reza_rahman
    JavaDay Taipei 2014 was held at the Taipei International Convention Center on August 1st. Organized by Oracle University, it is one of the largest Java developer events in Taiwan. This was another successful year for JavaDay Taipei with a fully sold out venue packed with youthful, energetic developers (this was my second time at the event and I have already been invited to speak again next year!). In addition to Oracle speakers like me, Steve Chin and Naveen Asrani, the event also featured a bevy of local speakers including Taipei Java community leaders. Topics included Java SE, Java EE, JavaFX, cloud and Big Data. It was my pleasure and privilege to present one of the opening keynotes for the event. I presented my session on Java EE titled "JavaEE.Next(): Java EE 7, 8, and Beyond". I covered the changes in Java EE 7 as well as what's coming in Java EE 8. I demoed the Cargo Tracker Java EE BluePrints. I also briefly talked about Adopt-a-JSR for Java EE 8. The slides for the keynote are below (click here to download and view the actual PDF): It appears your Web browser is not configured to display PDF files. No worries, just click here to download the PDF file. In the afternoon I did my JavaScript + Java EE 7 talk titled "Using JavaScript/HTML5 Rich Clients with Java EE 7". This talk is basically about aligning EE 7 with the emerging JavaScript ecosystem (specifically AngularJS). The talk was completely packed. The slide deck for the talk is here: JavaScript/HTML5 Rich Clients Using Java EE 7 from Reza Rahman The demo application code is posted on GitHub. The code should be a helpful resource if this development model is something that interests you. Do let me know if you need help with it but the instructions should be fairly self-explanatory. I am delivering this material at JavaOne 2014 as a two-hour tutorial. This should give me a little more bandwidth to dig a little deeper, especially on the JavaScript end. I finished off Java Day Taipei with my talk titled "Using NoSQL with ~JPA, EclipseLink and Java EE" (this was the last session of the conference). The talk covers an interesting gap that there is surprisingly little material on out there. The talk has three parts -- a birds-eye view of the NoSQL landscape, how to use NoSQL via a JPA centric facade using EclipseLink NoSQL, Hibernate OGM, DataNucleus, Kundera, Easy-Cassandra, etc and how to use NoSQL native APIs in Java EE via CDI. The slides for the talk are here: Using NoSQL with ~JPA, EclipseLink and Java EE from Reza Rahman The JPA based demo is available here, while the CDI based demo is available here. Both demos use MongoDB as the data store. Do let me know if you need help getting the demos up and running. After the event the Oracle University folks hosted a reception in the evening which was very well attended by organizers, speakers and local Java community leaders. I am extremely saddened by the fact that this otherwise excellent trip was scarred by terrible tragedy. After the conference I joined a few folks for a hike on the Maokong Mountain on Saturday. The group included friends in the Taiwanese Java community including Ian and Robbie Cheng. Without warning, fatal tragedy struck on a remote part of the trail. Despite best efforts by us, the excellent Taiwanese Emergency Rescue Team and World class Taiwanese physicians we were unable to save our friend Robbie Cheng's life. Robbie was just thirty-four years old and is survived by his younger brother, mother and father. Being the father of a young child myself, I can only imagine the deep sorrow that this senseless loss unleashes. Robbie was a key member of the Taiwanese Java community and a Java Evangelist at Sun at one point. Ironically the only picture I was able to take of the trail was mere moments before tragedy. I thought I should place him in that picture in profoundly respectful memoriam: Perhaps there is some solace in the fact that there is something inherently honorable in living a bright life, dying young and meeting one's end on a beautiful remote mountain trail few venture to behold let alone attempt to ascend in a long and tired lifetime. Perhaps I'd even say it's a fate I would not entirely regret facing if it were my own. With that thought in mind it seems appropriate to me to quote some lyrics from the song "Runes to My Memory" by legendary Swedish heavy metal band Amon Amarth idealizing a fallen Viking warrior cut down in his prime: "Here I lie on wet sand I will not make it home I clench my sword in my hand Say farewell to those I love When I am dead Lay me in a mound Place my weapons by my side For the journey to Hall up high When I am dead Lay me in a mound Raise a stone for all to see Runes carved to my memory" I submit my deepest condolences to Robbie's family and hope my next trip to Taiwan ends in a less somber note.

  • Database for survey

    - by zfm
    One of my job now is to design a database for a survey. Let's say we have a series of questions (web-based), in which one page contains one question. Not every person will be given the same questions, those are based on their previous answers and also randomness. I would like to know whether it is better to have database like this user question answer userX question1 answer1A userX question2 answer2C userX question5 answer5F userY question1 answer1B userY question3 answer3B userY question6 answer6D ... or user q1 q2 q3 q4 q5 q6 userX 1A 2C null null 5F null userY 1B null 3B null null 6D ... My idea here is, using the second approach seems better, however I would like to know whether updating the table is (much) slower than inserting a new row? Also with the first approach, I can omit having some null answers. The total questions given are fix, the client wont add any more question later on. So my question is, what will you do if you were me?

  • Wireframing: A Day In the Life of UX Workshop at Oracle

    - by ultan o'broin
    The Oracle Applications User Experience team's Day in the Life (DITL) of User Experience (UX) event was run in Oracle's Redwood Shores HQ for Oracle Usability Advisory Board (OUAB) members. I was charged with putting together a wireframing session, together with Director of Financial Applications User Experience, Scott Robinson (@scottrobinson). Example of stunning new wireframing visuals we used on the DITL events. We put on a lively show, explaining the basics of wireframing, the concepts, what it is and isn't, considerations on wireframing tool choice, and then imparting some tips and best practices. But the real energy came when the OUAB customers and partners in the room were challenge to do some wireframing of their own. Wireframing is about bringing your business and product use cases to life in real UX visual terms, by creating a low-fidelity drawing to iterate and agree on in advance of prototyping and coding what is to be finally built and rolled out for users. All the best people wireframe. Leonardo da Vinci used "cartoons" on some great works, tracing outlines first and using red ochre or charcoal dropped through holes in the tracing parchment onto the canvas to outline the subject. (Image distributed under Wikimedia commons license) Wireframing an application's user experience design enables you to: Obtain stakeholder buy-in. Enable faster iteration of different designs. Determine the task flow navigation paths (in Oracle Fusion Applications navigation is linked with user roles). Develop a content strategy (readability, search engine optimization (SEO) of content, and so on) Lay out the pages, widgets, groups of features, and so on. Apply usability heuristics early (no replacement for usability testing, but a great way to do some heavy-lifting up front). Decide upstream which functional user experience design patterns to apply (out of the box solutions that expedite productivity). Assess which Oracle Application Development Framework (ADF) or equivalent technology components can be used (again, developer productivity is enhanced downstream). We ran a lively hands-on exercise where teams wireframed a choice of application scenarios using the time-honored tools of pen and paper. Scott worked the floor like a pro, pointing out great use of features, best practices, innovations, and making sure that the whole concept of wireframing, the gestalt, transferred. "We need more buttons!" The cry of the energized. Not quite. The winning wireframe session (online shopping scenario) from the Applications UX DITL event shown. Great fun, great energy, and great teamwork were evident in the room. Naturally, there were prizes for the best wireframe. Well, actually, prizes were handed out to the other attendees too! An exciting, slightly different aspect to delivery of this session made the wireframing event one of the highlights of the day. And definitely, something we will repeat again when we get the chance. Thanks to everyone who attended, contributed, and helped organize.

  • Force Your Mac to Sort Folders on Top of Files (Windows Style)

    - by Eric Z Goodnight
    Even die-hard Mac converts have their issues with Mac OS, and one of those problems is that OS X lists folders mixed in with all other files. Here’s how to fix that in under five minutes with a clever hack. You know you’ve had that issue. You’ve dug through your files looking for that one elusive folder, and because it’s jumbled in with all the other stuff, it’s more or less impossible to find. Have no fear, with no downloads or silly plug-in software, you can finally make Mac OS behave like Windows and Linux and list those folders in the proper order.  How To Encrypt Your Cloud-Based Drive with BoxcryptorHTG Explains: Photography with Film-Based CamerasHow to Clean Your Dirty Smartphone (Without Breaking Something)

  • Optimizing data downloaded via 'link' media queries and asynchronous loading

    - by adam-asdf
    I have a website that tries to make sensible use of media queries and avoid 'expensive' CSS for users of mobile devices. My eventual goal is to make it 'mobile-first' but for now, since it is based on Twitter Bootstrap it isn't. I included some background images (Base64 encoded) and styles that would only apply to "full-size" browsers in a separate stylesheet loaded asynchronously via modernizr.load. In Firefox (but not webkit browsers) it makes it so that if you navigate away from the homepage and then return, the content (specifically, all those extras) 'blinks' when it finishes loading...or maybe I should say reloading. If, instead of using modernizr.load, I include that stylesheet via a link... in the head with a media query attribute will it prevent the data from being downloaded by non-matching browsers (mobile, based on screensize) that it is inapplicable to?

  • Displaying and updating score in Android (OpenGL ES 2)

    - by user16547
    I'm using a FrameLayout where I have a GLSurfaceView at the bottom and a few Views on top of it. One of those Views is a TextView that displays the current score. Here's how I'm updating the score TextView based on what happens in my game loop: whenever an event happens that increases the score, I call activity.runOnUiThread(updater), where activity is the activity that has the above FrameLayout (my main game activity) and updater is just a Runnable that increments the score. From my understanding, using runOnUiThread() from the OpenGL thread is standard practice - otherwise you'll get an exception, I can't remember its name. The problem is that there's a very noticeable lag between the event and the score update. For example the character gets a coin, but the coin count is not updated quickly. I tried summing all the score events from my game loop and calling runOnUiThread() only once per loop, but it doesn't seem to make much of a difference - the lag is still noticeable. How can I improve my design to avoid this lag?

  • How much should I charge for a web app

    - by Kostas
    I am a freelance web developer and I am working on a PHP/MySQL/Javascript based project. It's a web app that uses a custom CMS with user types, followers system, search forms, blogs, social integration. It will take about 3 months to finish, according to a roadmap I make (based on current development stage) and about a month after that for bug fixing and testing. So I have to tell them a price. What price range you think it's appropriate?? (It's a good regular client, so I want something reasonable) Can you give me some ideas?? Thanks.
