  • Code for Parallelism Features Tour

    Last year I linked to a screencast that shows off many VS2010 features delivered by the Parallel Computing team.There have been requests for the code used to demonstrate the features. Like with all my screencasts, you can see all the code in action, so you could simply type it in. To save you doing that though, you may download the two files with the demo code here: MM.cs and Program.cs. HTH. Comments about this post welcome at the original blog.

  • OTN Latinoamérica Tour 2012

    - by Dana Singleterry
    Better late than never. Sorry for the delay on getting this content up for all of you and thanks again for your attendance. A number of excellent questions came out of the sessions I delivered and herein I'm providing you with the content, in pdf format, for those sessions. I'm also providing pointers to Forms to ADF integration/migration as well as some details around OAF as used in E-Business Suite and ADF. Here's the sessions delivered by location. Click on any of the links to download the session content in pdf format. Montevideo Uruguay: Is Oracle ADF Simpler than Oracle Forms? Understanding the Fusion Development Platform Building Web Data Dashboards Without Coding Buenos Aires, Argentina: Is Oracle ADF Simpler than Oracle Forms? Developing Cross Device Mobile Applications Sao Paulo, Brazil Understanding the Fusion Development Platform Is Oracle ADF Simpler than Oracle Forms? A brief note on Form Integration & Migration: Does your organization have an Oracle Forms application that you'd like to migrate to ADF? Or, perhaps you're an Oracle Forms Developer and want to modernize your application development skills? If so, you've come to the right place! This section will strive to answer common questions that arise as you move from Forms to ADF. Our Oracle Forms Statement of Direction points out that Oracle is committed to the long-term support of Oracle Forms and Reports. However, many customers feel they are outgrowing their Forms applications. Users are demanding more sophisticated and interactive users interfaces. Executives are requiring SOA-enabled applications that integrate with peripheral services. Development leads are encouraging a more modern approach to application development, including adherence to design patterns like MVC. So even as Oracle still supports Forms, the list of reasons to move off of it is becoming more compelling and is only gaining further momentum by the fact that Oracle's own Fusion Applications are using ADF. Developers and organizations looking to align with both the technology stack and look-and-feel of Fusion Applications are choosing ADF, and thus reaping the benefits of years of best practices in enterprise application development that are baked into the ADF framework. So, if you decide to migrate off of Forms for any of these reasons, ADF is the way to go. Grant Ronald has published a video of our position on the subject, along with an ODTUG article explaining our direction. These materials explain that there are other migration tools/frameworks/paths, but the best choice is usually to follow Gartner's recommendation that if you are going to migrate off of Oracle Forms, ADF is the least risky and least costly migration path. Please visit the Oracle Forms page here. For details around OAF as used in E-Business Suite (EBS) and when to use ADF with EBS you can review the following blogs from Shay Shmeltzer. To ADF or to OAF? or Can I use ADF with Oracle E-Business Suite?

  • NRF Week - Disney Store Tour

    - by sarah.taylor(at)oracle.com
    Disney has created a real buzz at this year's NRF event. Yesterday morning we began the Oracle Retail Exchange program with a visit to the flagship Disney store in Times Square. Additionally Oracle made a key announcement with Disney  on Oracle Retail's Point of Sale implementation in 330 stores worldwide. Today   Disney's Steve Finney gave a super session on The Magic of Disney at the NRF Big Show. We also saw Disney making an exclusive news announcement about their plans for Global store openings at the Oracle trade show stand - with a little help from Mickey and Minnie Mouse. Disney Stores have been entirely reinvented since the company in 2008 took ownership after previously franchising the retail arm of the business. They have subsequently been a strong Oracle partner and technology has played a key role in their re imagination of the store environment. The new Imagination stores have a 20% higher footfall and margins are up 25%. The Disney brand is synonymous with magical and memorable experiences for children of all ages. The company is achieving a unique retail experience that delights children and shareholders alike! Technology is a key pillar in helping to deliver on both a strong operating model and a unique customer experience - the best thirty minutes in a child's day is their aim. Steve Finney this morning said their technology has to be as reliable as a theme park ride. Store experiences are much more enjoyable when there are short waiting times and children can interact with their favourite characters through magic mirrors, mobile point of sale, touch screens and custom animations that are digitally transmitted to stores globally. The Oracle Retail Point of Sale with iPad touch screens reduces check out times, stores customer data, ensures that promotions are delivered accurately and reduces losses. This means higher levels of guest conversion, increased availability and convenience for customers who want to check availability at other locations. Disney is a pioneer. At NRF's 100th show, we had the privilege of learning from a retailer using technology as a creative force to drive their business forward.

  • Craftsmanship Tour Day 1: Didit Long Island

    - by Liam McLennan
    On Monday I was at Didit for my first ever craftsmanship visit. Didit seem to occupy a good part of a non-descript building in Rockville Centre Long Island. Since I had arrived early from Seattle I had some time to kill, so I stopped at the Rockville Diner on the corner of N Park Ave and Sunrise Hwy. I thoroughly enjoyed the pancakes and the friendly service. After walking to the Didit office I met Rik Dryfoos, the Didit Engineering Manager who organised my visit, and got the introduction to Didit and the work they are doing. I spent the morning in the room shared by the Didit developers, who are working on some fascinating deep engineering problems. After lunch at a local Thai place I setup a webcam to record an interview with Rik and Matt Roman (Didit VP of Engineering). I had a lot of trouble with the webcam, including losing several minutes of conversation, but in the end I was very happy the result. Here are the full interviews with Rik and Matt: Interview with Rik Dryfoos Interview with Matt Roman We had a great chat, much of which is captured in the recording. It was such great conversation that I almost missed my train to Manhattan. I’m sure Didit will continue to do well with such a dedicated and enthusiastic team. I sincerely thank them for hosting me for the day. If you are looking for a true agile environment and the opportunity to work with a high quality team then you should talk to Didit.

  • A tour of the GlassFish 3.1.2 DCOM support

    - by alexismp
    While we've mentioned the DCOM support in GlassFish 3.1.2 several times before, you'll probably find Byron's DCOM blog entry to be useful if you're using Windows as a deployment platform for your GlassFish cluster. Byron discusses how DCOM is used to communicate with remote Windows nodes participating in a GlassFish cluster, what Java libraries were used to wrap around DCOM, what new asadmin commands were addd (in particular validate-dcom) as well as some tips to make this all work on your specific environment. In addition to this blog post, you should considering reading the official product documentation : • Considerations for Using DCOM for Centralized Administration • Setting Up DCOM and Testing the DCOM Set Up

  • Do MORE with WebCenter - Webcast Overview & TIES Tour

    - by Michael Snow
    Today's post is from Michelle Huff, Senior Director, Product Management, Oracle WebCenter `````````````````  In case you missed it, I presented on a webcast yesterday focused on how you can “Do More with Oracle WebCenter – Expand Beyond Content Management.” As you may remember, we rebranded Oracle’s Enterprise Content Management (ECM) Suite, which some people knew by the wonderfully techie three-letter acronyms -- UCM, URM & IPM -- to Oracle WebCenter Content last year. Since it’s a unified ECM platform, I’ve seen many customers over the years continue to expand the number of content-centric solutions and application integrations powered by WebCenter throughout their organizations. But, did you know WebCenter also provides portal, collaboration and web experience management capabilities as well? This enables you to leverage your existing investment in the WebCenter platform as well as the information you’re managing to create engaging sites, collaborative spaces, or self-service portals and composite applications. In the webcast I walked through six different ways that you can do more with WebCenter: Collaborative content contribution and sharing environment Share content across intranets and extranets Combine content in composite applications Create targeted online experiences Manage interactive social experiences Optimize multi-channel customer experiences Joining me on the call was Greg Utecht with TIES. TIES is a joint powers cooperative owned by 46 Minnesota school districts, represents 514 schools – and provides software applications, hardware and software, internet service and professional development designed by educators for education. I was having a lot of fun over the past few days talking with Greg about the TIES implementation and future plans with WebCenter. He joined me on the call for a little Q&A to explain how he’s using WebCenter today for their iContent implementation for document management, records management and archiving. And also covered how they have expanded their implementation to create a collaborative space called their HRPay System with WebCenter to facilitate collaboration and to better engage their users within the school districts. During our conversation a few questions came from the audience about their implementation. They were curious to see how the system looked – so let’s take a peak. This first screenshot shows the screen that a human resources or payroll worker in one of our member districts would see upon logging in, based on their credentials and role in their district. This shows the result of clicking on the SUBSCRIBE link on the main page. It allows the user to subscribe to parts of the portal which will e-mail him/her when those are updated in any way. This shows the screen that a human resources or payroll worker in one of our member districts would see upon clicking on the Resources link. This shows the screen that a human resources or payroll worker in one of our member districts would see upon clicking on the Finance Advisory link. It shows the discussion threads and document sharing areas. This shows the screen that appears when the forum topic on the preceding screen is clicked. This shows the screen portlet up close with shared documents. This shows the screen that appears when a shared document is clicked on. Note that there is also a download button and an update button, meaning people can work on these collaboratively. If you missed the webcast, check it out! You can watch the replay OnDemand HERE. If you attended the webcast, thanks for joining - I hoped you learned a little from the session. I learned that kids are getting digital report cards today! Wow, have times changed with technology. Uh oh, is this when I start saying “You know, back in my days…?”

  • Screenshot Tour: 10 New Features in Android 4.2 Jelly Bean

    - by Chris Hoffman
    Android 4.2 improves on Android 4.1 in numerous ways, adding a variety of new features. Android 4.2 isn’t as big an update as Android 4.1, also called Jelly Bean, but it’s a definite improvement. If you have a Nexus 7 or Galaxy Nexus, you should be getting this update very soon. Unfortunately, it will likely take quite a bit longer for manufacturers to ship Android 4.2 on non-Nexus devices.

  • A Tour of the 20 Built-in Apps on Windows 8 and What They Can Do

    - by Chris Hoffman
    Windows 8’s new touch-first Modern interface includes quite a few apps. Before you start looking at the Windows Store to find new apps, take a look at the included apps and what they can do. These apps share a few things in common. They all have a minimal feel that emphasizes content, most have support for live tiles that show updated information on the Start screen, and most push Microsoft’s online services.

  • Screenshot Tour: Ubuntu Touch 14.04 on a Nexus 7

    - by Chris Hoffman
    Ubuntu 14.04 LTS will “form the basis of the first commercially available Ubuntu tablets,” according to Canonical. We installed Ubuntu Touch 14.04 on our own hardware to see what those tablets will be like. We don’t recommend installing this yourself, as it’s still not a polished, complete experience. We’re using “Ubuntu Touch” as shorthand here — apparently this project’s new name is “Ubuntu For Devices.” The Welcome Screen Ubuntu’s touch interface is all about edge swipes and hidden interface elements — it has a lot in common with Windows 8, actually. You’ll see the welcome screen when you boot up or unlock a Ubuntu tablet or phone. If you have new emails, text messages, or other information, it will appear on this screen along with the time and date. If you don’t, you’ll just see a message saying “No data sources available.” The Dash Swipe in from the right edge of the welcome screen to access the Dash, or home screen. This is actually very similar to the Dash on Ubuntu’s Unity desktop. This isn’t a surprise — Canonical wants the desktop and touch versions of Ubuntu to use the same code. In the future, the desktop and touch versions of Ubuntu will use the same version of Unity and Unity will adjust its interface depending on what type of device your’e using. Here you’ll find apps you have installed and apps available to install. Tap an installed app to launch it or tap an available app to view more details and install it. Tap the My apps or Available headings to view a complete list of apps you have installed or apps you can install. Tap the Search box at the top of the screen to start searching — this is how you’d search for new apps to install. As you’d expect, a touch keyboard appears when you tap in the Search field or any other text field. The launcher isn’t just for apps. Tap the Apps heading at the top of the screen and you’ll see hidden text appear — Music, Video, and Scopes. This hidden navigation is used throughout Ubuntu’s different apps and can be easy to miss at first. Swipe to the left or right to move between these screens. These screens are also similar to the different panels in Unity on the desktop. The Scopes section allows you to view different search scopes you have installed. These are used to search different sources when you start a search from the Dash. Search from the Music or Videos scopes to search for local media files on your device or media files online. For example, searching in the Music scope will show you music results from Grooveshark by default. Navigating Ubuntu Touch Swipe in from the left edge anywhere on the system to open the launcher, a bar with shortcuts to apps. This launcher is very similar to the launcher on the left of Ubuntu’s Unity desktop — that’s the whole idea, after all. Once you’ve opened an app, you can leave the app by swiping in from the left. The launcher will appear — keep moving your finger towards the right edge of teh screen. This will swipe the current app off the screen, taking you back to the Dash. Once back on the Dash, you’ll see your open apps represented as thumbnails under Recent. Tap a thumbnail here to go back to a running app. To remove an app from here, long-press it and tap the X button that appears. Swipe in from the right edge in any app to quickly switch between recent apps. Swipe in from the right edge and hold your finger down to reveal an application switcher that shows all your recent apps and lets you choose between them. Swipe down from the top of the screen to access the indicator panel. Here you can connect to Wi-Fi networks, view upcoming events, control GPS and Bluetooth hardware, adjust sound settings, see incoming messages, and more. This panel is for quick access to hardware settings and notifications, just like the indicators on Ubuntu’s Unity desktop. The Apps System settings not included in the pull-down panel are available in the System Settings app. To access it, tap My apps on the Dash and tap System Settings, search for the System Settings app, or open the launcher bar and tap the settings icon. The settings here a bit limited compared to other operating systems, but many of the important options are available here. You can add Evernote, Ubuntu One, Twitter, Facebook, and Google accounts from here. A free Ubuntu One account is mandatory for downloading and updating apps. A Google account can be used to sync contacts and calendar events. Some apps on Ubuntu are native apps, while many are web apps. For example, the Twitter, Gmail, Amazon, Facebook, and eBay apps included by default are all web apps that open each service’s mobile website as an app. Other applications, such as the Weather, Calendar, Dialer, Calculator, and Notes apps are native applications. Theoretically, both types of apps will be able to scale to different screen resolutions. Ubuntu Touch and Ubuntu desktop may one day share the same apps, which will adapt to different display sizes and input methods. Like Windows 8 apps, Ubuntu apps hide interface elements by default, providing you with a full-screen view of the content. Swipe up from the bottom of an app’s screen to view its interface elements. For example, swiping up from the bottom of the Web Browser app reveals Back, Forward, and Refresh buttons, along with an address bar and Activity button so you can view current and recent web pages. Swipe up even more from the bottom and you’ll see a button hovering in the middle of the app. Tap the button and you’ll see many more settings. This is an overflow area for application options and functions that can’t fit on the navigation bar. The Terminal app has a few surprising Easter eggs in this panel, including a “Hack into the NSA” option. Tap it and the following text will appear in the terminal: That’s not very nice, now tracing your location . . . . . . . . . . . .Trace failed You got away this time, but don’t try again. We’d expect to see such Easter eggs disappear before Ubuntu Touch actually ships on real devices. Ubuntu Touch has come a long way, but it’s still not something you want to use today. For example, it doesn’t even have a built-in email client — you’ll have to us your email service’s mobile website. Few apps are available, and many of the ones that are are just mobile websites. It’s not a polished operating system intended for normal users yet — it’s more of a preview for developers and device manufacturers. If you really want to try it yourself, you can install it on a Wi-Fi Nexus 7 (2013), Nexus 10, or Nexus 4 device. Follow Ubuntu’s installation instructions here.

  • Cities from Space: A Tour of Urban Planning Patterns

    - by Jason Fitzpatrick
    While many cities developed haphazardly and organically with little structured planning, other cities were developed following strict organization–organization that reveals itself beautifully when seen from space. Wired magazine shares a roundup of ten well-planned cities viewed with a satellite’s eye. Among the roundup our favorite is the oldest, seen in the photo above: This nine-pointed fortress is perhaps the best example of a planned city from the Renaissance. Palmanova was built in 1593 and is located in the northeastern corner of Italy near the border with Slovenia. It was intended to be home to a completely self-reliant utopian community that could also defend itself against the Ottomans. It had three guarded entrances, ramparts between each of the star points and eventually a moat. Sadly, nobody was willing to move there. Eventually it was used as free housing for pardoned criminals. Today it is a national monument, a tourist destination and home to around 5,000 people. Hit up the link below to check out the other nine well-planned entries in the roundup.

  • Virtual Tour Viewer?

    - by Jessica
    My client wanted me to put a virtual tour video on their website. They bought it from "ForRent.com". They forwarded it to me, and its nothing but the panoramic images. When I asked about some type of viewer/player, they simply stated I would need js or flash installed on my computer (i do). Of course, thats not going to magically put these photos into a virtual tour. This is my first time working with a virtual tour, so does anyone know of any viewers I could just put the images into so that the user could click and drag?

  • Improve SQL strategy - denormalize in object-children-images case

    - by fesja
    Hi, I have a Tour object which has many Place objects. For the list of tours, I want to show some info of the tour, the number of places of the tour, and three Place's images. Right one my SQL queries are (i'm using Doctrine with Symfony on MySQL) get Tour get Tour 1 places get Tour 2 places get Tour 3 places ... get Tour n places If I have a three Tour list, it's not so bad; but I'm sure it can get bad if I do a 10-20 tour-list. So, thinking on how to improve the queries I've thought of several measures: Having a place count cache Storing the urls of three images on a new tour field. The problem with 2. is that if I change the image, I have to check all the tours to update that image for another one. What solution do you think is best to scale the system in a near future? Any other suggestion. thanks!

  • How do I disable the firewall on blackberry?

    - by user15660
    I own a Blackberry 9630 tour.(Sprint). The firewall is enabled with a lock sign and grayed out. I'm not able to disable it. Because of this many of my blackberry apps don't work as it gives a message "The application has tried to open a connection that's not allowed by your IT policy". I tried all options and there's nothing to disable. This is a personal blackberry and I don't have an IT policy on it. I did all methods like wiping, formatting/resetting to factory settings acc. to blackberry site by running their reset app from PC etc etc. but nothing works I tried CrackUtil for blackberry and that worked and wiped the blackberry. I restored my bb and started using it just to notice that the firewall is enabled back after a desktop manager connection to PC. I even made sure the policy.bin file on PC is a regular one with no IT policy. How do I get this disabled? I had the same problem on my old blackberry 8330 and crackutil disabled the firewall. but after a few days after a desktop manager update of blackberry OS and other small stuff the firewall got enabled again. Please give me a solutions to disable the firewall on blackberry

  • need help building a stored procedure that takes rows from one table into another.

    - by MyHeadHurts
    alright i built this stored procedure to take the columns from a stagging table and copy them into my other table, but if these four columns are duplicates it wont insert the rows, works fine. however, what i want to do is if only the tour, taskname and deptdate are the same, then i will update the rest of the information. and if all four columns are the same dont instert. INSERT INTO dashboardtasks1 SELECT [tour], [taskname], [deptdate], [tasktype], [desc], [duedate], [compdate], [comments], [agent], [compby], [graceperiod] FROM staggingtasks WHERE NOT EXISTS(SELECT * FROM dashboardtasks1 WHERE (staggingtasks.tour=dashboardtasks1.tour and staggingtasks.taskname=dashboardtasks1.taskname and staggingtasks.deptdate=dashboardtasks1.deptdate and staggingtasks.duedate=dashboardtasks1.duedate ) ) i saw something like this INSERT INTO table (a,b,c) VALUES (1,2,3) ON DUPLICATE KEY UPDATE c=c+1; UPDATE table SET c=c+1 WHERE a=1; but how could i do it if my stated 3 columns are the samed then update? or is there a way to do this with an if statement and use 2 different queries, but how would my if statement work would it check if the row exists in the table i am uploading to and then run the insert statement? or what if i did something like IF EXISTS (SELECT * FROM dashboardtasks WHERE staggingtasks.tour=dashboardtasks.tour and staggingtasks.taskname=dashboardtasks.taskname and staggingtasks.deptdate=dashboardtasks.deptdate ) begin UPDATE [dashboardtasks] SET [tour] = staggingtasks.tour, [taskname] = staggingtasks.taskname, [deptdate] = staggingtasks.deptdate, [tasktype] = staggingtasks.tasktype, [desc] = staggingtasks.desc, [duedate] = staggingtasks.duedate, [compdate] = staggingtasks.compdate, [comments] = staggingtasks.comments, [agent] = staggingtasks.agent, [compby] = staggingtasks.compby, [graceperiod] = staggingtasks.graceperiod end else EXISTS (SELECT * FROM dashboardtasks WHERE staggingtasks.tour=dashboardtasks.tour and staggingtasks.taskname=dashboardtasks.taskname and staggingtasks.deptdate=dashboardtasks.deptdate and staggingtasks.duedate=dashboardtasks.duedate ) begin INSERT INTO dashboardtasks1 SELECT [tour], [taskname], [deptdate], [tasktype], [desc], [duedate], [compdate], [comments], [agent], [compby], [graceperiod] FROM staggingtasks WHERE NOT EXISTS(SELECT * FROM dashboardtasks1 WHERE (staggingtasks.tour=dashboardtasks1.tour and staggingtasks.taskname=dashboardtasks1.taskname and staggingtasks.deptdate=dashboardtasks1.deptdate and staggingtasks.duedate=dashboardtasks1.duedate ) ) end end

  • Trouble with go tour crawler exercise

    - by David Mason
    I'm going through the go tour and I feel like I have a pretty good understanding of the language except for concurrency. On slide 71 there is an exercise that asks the reader to parallelize a web crawler (and to make it not cover repeats but I haven't gotten there yet.) Here is what I have so far: func Crawl(url string, depth int, fetcher Fetcher, ch chan string) { if depth <= 0 { return } body, urls, err := fetcher.Fetch(url) if err != nil { ch <- fmt.Sprintln(err) return } ch <- fmt.Sprintf("found: %s %q\n", url, body) for _, u := range urls { go Crawl(u, depth-1, fetcher, ch) } } func main() { ch := make(chan string, 100) go Crawl("http://golang.org/", 4, fetcher, ch) for i := range ch { fmt.Println(i) } } The issue I have is where to put the close(ch) call. If I put a defer close(ch) somewhere in the Crawl method, then I end up writing to a closed channel in one of the spawned goroutines, since the method will finish execution before the spawned goroutines do. If I omit the call to close(ch), as is shown in my example code, the program deadlocks after all the goroutines finish executing but the main thread is still waiting on the channel in the for loop since the channel was never closed.

  • Graph Tour with Uniform Cost Search in Java

    - by user324817
    Hi. I'm new to this site, so hopefully you guys don't mind helping a nub. Anyway, I've been asked to write code to find the shortest cost of a graph tour on a particular graph, whose details are read in from file. The graph is shown below: http://img339.imageshack.us/img339/8907/graphr.jpg This is for an Artificial Intelligence class, so I'm expected to use a decent enough search method (brute force has been allowed, but not for full marks). I've been reading, and I think that what I'm looking for is an A* search with constant heuristic value, which I believe is a uniform cost search. I'm having trouble wrapping my head around how to apply this in Java. Basically, here's what I have: Vertex class - ArrayList<Edge> adjacencies; String name; int costToThis; Edge class - final Vertex target; public final int weight; Now at the moment, I'm struggling to work out how to apply the uniform cost notion to my desired goal path. Basically I have to start on a particular node, visit all other nodes, and end on that same node, with the lowest cost. As I understand it, I could use a PriorityQueue to store all of my travelled paths, but I can't wrap my head around how I show the goal state as the starting node with all other nodes visited. Here's what I have so far, which is pretty far off the mark: public static void visitNode(Vertex vertex) { ArrayList<Edge> firstEdges = vertex.getAdjacencies(); for(Edge e : firstEdges) { e.target.costToThis = e.weight + vertex.costToThis; queue.add(e.target); } Vertex next = queue.remove(); visitNode(next); } Initially this takes the starting node, then recursively visits the first node in the PriorityQueue (the path with the next lowest cost). My problem is basically, how do I stop my program from following a path specified in the queue if that path is at the goal state? The queue currently stores Vertex objects, but in my mind this isn't going to work as I can't store whether other vertices have been visited inside a Vertex object. Help is much appreciated! Josh
