  • SQL Cruise Alaska 2011

    - by Grant Fritchey
    I had the extreme good fortune to get sent on the last SQL Cruise to Alaska. I love my job. In case you don't what this is, SQL Cruise is a trip on a cruise ship during which you get to attend classes while on the boat, learning all about SQL Server and related topics as well as network with the instructors and the other Cruisers. Frankly, it's amazing. Classes ran from Monday, 5/30, to Saturday, 6/4. The networking was constant, between classes, at night on cruise ship, out on excursions in Alaskan rainforests and while snorkeling in ocean waters. Here's a run down of the experience from my point of view. Because I couldn't travel out 2 days early, I missed the BBQ that occurred the day before the cruise when many of the Cruisers received their swag bags. Some of that swag came from Red Gate. I researched what was useful on a cruise like this and purchased small flashlights and binoculars for all the Cruisers. The flashlights were because, depending on your cabin, ships can be very dark. The binoculars were so that the cruisers could watch all the beautiful landscape as it flowed by. I would have liked to have been there when the bags were opened, but I heard from several people that they appreciated the gifts. Cruisers "In" the hot tub. Pictured: Marjory Woody, Michele Grondin, Kyle Brandt, Grant Fritchey, John Halunen Sunday I went to board the ship with my wife. We had a bit of an adventure because I messed up our documents. It all worked out and we got on board to meet up at the back of the boat at one of the outdoor bars with the other Cruisers, thanks to tweets letting everyone know where to go. That was the end of electronic coordination on the trip (connectivity in Alaska was horrible for everyone except AT&T). The Cruisers were a great bunch of people and it was a real honor to meet them and get to spend time with them. After everyone settled into their cabins, our very first activity was a contest, sponsored by Red Gate. The Cruisers, in an effort to get to know each other and the ship, were required to go all over taking various photographs, some of them hilarious. The winning team of three would all win prizes. Some of the significant others helped out and I tagged along with a team that tied for first but lost the coin toss. The winning team consisted of Christina Leo (blog|twitter), Ryan Malcom (twitter), Neil Hambly (blog|twitter). They then had to do math and identify the cabin with the lowest prime number, oh, and get a picture of it and be the first to get back up to the bar where we were waiting. Christina came in first and very happily carried home an Ipad2. Ryan won a 1TB portable hard drive and Neil won a wireless mouse (picture below, note my special SQL Server Central Friday Shirt. Thanks Steve (blog|twitter)). Winners: Christina Leo, Neil Hambly, Ryan Malcolm. Just Lucky: Grant Fritchey Monday morning classes started. Buck Woody (blog|twitter) was a special guest speaker on this cruise. His theme was "Three C's on the High Seas: Career, Communication and Cloud." The first session was all on Career. I'm not going to type out all my notes from the session, but let's just say, if you get the chance to hear Buck talk about how to manage your career, I suggest you attend. I have a ton of blog posts that I'll be putting together over the next several months (yes, months) both here and over on ScaryDBA. I also have a bunch of work I'm going to be doing to get my career performance bumped up a notch or two (and let's face it, that won't be easy). Later on Monday, Tim Ford (blog|twitter) did a session on DMOs. Specifically the session was on Tim's Period Table of DMOs that he has put together, and how to use some of the more interesting DMOs in your day to day job. It was a great session, packed with good information. Next, Brent Ozar (blog|twitter) did a session on how to monitor and guide SAN configuration for the DBA that doesn't have access to the SAN. That was some seriously useful information. Tuesday morning we only had a single class. Kendra Little (blog|twitter) taught us all about "No Lock for Yes Fun".  It was all about the different transaction isolation levels and how they work. There is so often confusion in this area and Kendra does a great job in clarifying the information. Also, she tosses in her excellent drawings to liven up the presentation. Then it was excursion time in Juneau. My wife and I, along with several other Cruisers, took a hike up around the Mendenhall Glacier. It was absolutely beautiful weather and walking through the Alaskan rain forest was a treat. Our guide, Jason, was a great guy and it was a good day of hiking. Wednesday was an all day excursion in Skagway. My wife and I took the "Ghost and Good Time Girls" walking tour that ended up at a bar that used to be a brothel, the Red Onion. It was a great history of the town. We went back out and hit a few museums and exhibits. We also hiked up the side of the mountain to see the Dewey Lake and some great views of the town. Finally we hiked out to the far side of town to see the Gold Rush cemetery. Hiking done we went back to the boat and had a quiet dinner on our own. Thursday we cruised through Glacier Bay and saw at least four different glaciers including sitting next to the Marjory Glacier for  about an hour. It was amazing. Then it got better. We went into class with Buck again, this time to talk about Communication. Again, I've got pages of notes that I'm going to be referring back to for some time to come. This was an excellent opportunity to learn. Snorkelers: Nicole Bertrand, Aaron Bertrand, Grant Fritchey, Neil Hambly, Christina Leo, John Robel, Yanni Robel, Tim Ford Friday we pulled into Ketchikan. A bunch of us went snorkeling. Yes, snorkeling. Yes, in Alaska. Yes, snorkeling in the ocean in Alaska. It was fantastic. They had us put on 7mm thick wet suits (an adventure all by itself) so it was basically warm the entire time we were in the water (except for the occasional squirt of cold water down my back). Before we got in the water a bald eagle flew up and landed about 15 feet in front of us, which was just an incredible event. Then our guide pointed out about 14 other eagles in the area, hanging out in the trees. Wow! The water was pretty clear and there was a ton of things to see. That was absolutely a blast. Back on the boat I presented a session called Execution Plans: The Deep Dive (note the nautical theme). It seemed to go over well and I had several good questions come out of the session that will lead to new blog posts. After I presented, it was Aaron Bertrand's (blog|twitter) turn. He did a session on "What's New in Denali" that provided a lot of great information. He was able to incorporate new things straight out of Tech-Ed, so this was expanded beyond his usual presentation. The man really knows what he's talking about and communicates it well. Saturday we were travelling so there was time for a bunch of classes. Jeremiah Peschka (blog|twitter) did a great overview of some of the NoSQL databases and what they should be used for. The session was called "The Database is Dead" but it was really about how there are specific uses for these databases that SQL Server doesn't fill, but also that these databases can't replace SQL Server in other areas. Again, good material. Brent Ozar presented again with a session on Defensive Indexing. It was an overview of how indexes work and a deep dive into how to apply them appropriately in your databases to better support access. A good session, as you would expect. Then we pulled into Victoria, BC, in Canada and had a nice dinner with several of the Cruisers, including Denny Cherry (blog|twitter). After that it was back to Seattle on Sunday. By the way, the Science Fiction Museum in Seattle isn't a Science Fiction Museum any more. I was very disappointed to discover this. Overall, it was a great experience. I'm extremely appreciative of Red Gate for sending me and for Tim, Brent, Kendra and Jeremiah for having me. The other Cruisers were all amazing people and it was an honor & privilege to meet them and spend time with them. While this was a seriously fun time, it was also a very serious training opportunity with solid information coming from seasoned industry pros.

  • CMOTECH D-50 modem installation in Ubuntu 12.04

    - by Ricardo
    I have recently upgraded from 10.04 to 12.04. I had installed a 3G D-50 modem from CMOTECH. The program for Debian is provided by a Swedish company (ice.net). Usually after some mambo jambo of installung the libg++ libraries requested you can install it and runned in Ubuntu 8.04, 9.04, 10.04 and as far as I know in 11.04. When I upgraded and I click on the icon of ice.net it worked. However, I noticed that the usb D-50 modem was never mounted as usb and it didn't show up in the Lauchnpad or workspace (as when you plug a usb memory stick or another HD). I moved the icon from place in the launchpad and since when I click on the ice.net icon the same message appears: "please plug in your modem". The modem works (I've tested in Windows after this) and it blinks blue (sign that it works and picks up signal). If I type lsusb then I see that Ubuntu sees it on BUS address 006: Bus 006 Device 003: ID 16d8:6803 CMOTECH Co., Ltd. CNU-680 CDMA EV-DO modem I've tried wvdial without success. How can I get the D-50 usb modem mounted as in the previous versions of Ubuntu ?. Any help will be much appreciated. bests. Ricardo

  • The Social Business Thought Leaders - Steve Denning

    - by kellsey.ruppel
    How is the average organization doing? Not very well according to a number of recent books and reports. A few indicators provide quite a gloomy picture: Return on assets and invested capitals dropped to 25% of its value in 1965 in the entire US market (see The Shift Index by John Hagel) Firms are dying faster and faster with the average lifespan of companies listed in the S&P 500 index gone from 67 years in the 1920s to 15 years today (see Creative Disruption by Richard Foster) Employee engagement ratio, a high level indicator of an organization’s health proved to affect performance outcomes, does not exceed on average 20%-30% (see Employee Engagement, Gallup or The Engagement Gap, Towers Perrin) In one of the most enjoyable keynotes of the Social Business Forum 2012, Steve Denning (Author of Radical Management and Independent Management Consultant) explained why this is happening and especially what leaders should do to reverse the worrying trends. In this Social Business Thought Leaders series, we asked Steve to collapse some key suggestions in a 2 minutes video that we strongly recommend. Steve discusses traditional management - that set of principles and practices born in the early 20th century and largely inspired by thinkers such as Frederick Taylor and Henry Ford - as the main responsible for the declining performance of modern organizations. While so many things have changed in the last 100 or so years, most companies are in fact still primarily focused on maximizing profits and efficiency, cutting costs, coordinating individuals top-down through command and control. The issue is, in a knowledge intensive, customer centred, turbulent market like the one we are experiencing, similar concepts are not just alienating employees' passion but also destroying the last source of competitive differentiation left: creativity and the innovative potential. According to Steve Denning, in a phase change from old industrial to a creative, collaborative, knowledge economy, the answer is hidden in a whole new business ecosystem that puts the individual (both the employee and the customer) at the center of the organization. He calls this new paradigm Radical Management and in the video interview he articulates the huge challenges and amazing rewards our enterprises are facing during this inevitable transition.

  • Hack Apart a Highlighter to Create UV-Reactive Flowers [Science]

    - by ETC
    College students have long been hacking apart highlighters to create glowing bottles of booze to line their dorm room walls. Far more interesting, however, is the application of the hack to flowers. Many of you may remember a science class experiment from years gone by where in you put food coloring in a beaker and then some freshly cut white flowers; returning to the experiment a day later yielded flowers colored to match the dye you added. This little experiment relies on the same technique, only instead of blue food coloring the flowers suck up UV-reactive highlighter dye.

  • Embedding BIP just got easier!

    - by Tim Dexter
    To make up for yesterday's documentation faux pas, when I referenced Kan's blog as a source for the debug feature over Leslie's fine official documentation that had come out some time before Kan's blog. Apologies again Leslie! I noticed another new feature that I was unaware of in the New Features guide for 10.1.3.4.1. The ability to remove the BI Publisher header from the user interface so you can get this: instead of this. Useful? If you wanted to host BIP inside another application such as a portal or custom app, you can make the BIP UI app look much more integrated. By default you still get our 'blue' look and feel' but I have documented else where how you can change that. For instance, now you can have BIP hosted inside a BIEE instance and provide access to all the reports a user might wish to run with very little effort rather than picking and choosing what to bubble up to the dashboard. How do you do it? Get on over to the New Features guide and find out, there are some other goodies there too. Note to self, RTFM!

  • CERN Announces the Discovery of a Higgs-Boson-like Particle

    - by Jason Fitzpatrick
    CERN scientists dropped a press release today indicating they’ve found a particle consistent with the long sought after Higgs Boson particle–the “God” particle, that could help radically refine our understanding of Standard Model of Particle Physics. For years scientists at CERN have been harnessing the power of the Large Hadron Collider to answer fundamental questions about the nature of particles and the universe around us. In the above video John Ellis, a theoretical physicist, answers the question “What is the Higgs Boson?” The video pairs nicely with the CERN press release: “We observe in our data clear signs of a new particle, at the level of 5 sigma, in the mass region around 126 GeV. The outstanding performance of the LHC and ATLAS and the huge efforts of many people have brought us to this exciting stage,” said ATLAS experiment spokesperson Fabiola Gianotti, “but a little more time is needed to prepare these results for publication.” “The results are preliminary but the 5 sigma signal at around 125 GeV we’re seeing is dramatic. This is indeed a new particle. We know it must be a boson and it’s the heaviest boson ever found,” said CMS experiment spokesperson Joe Incandela. “The implications are very significant and it is precisely for this reason that we must be extremely diligent in all of our studies and cross-checks.” “It’s hard not to get excited by these results,” said CERN Research Director Sergio Bertolucci. “ We stated last year that in 2012 we would either find a new Higgs-like particle or exclude the existence of the Standard Model Higgs. With all the necessary caution, it looks to me that we are at a branching point: the observation of this new particle indicates the path for the future towards a more detailed understanding of what we’re seeing in the data.” How to Use an Xbox 360 Controller On Your Windows PC Download the Official How-To Geek Trivia App for Windows 8 How to Banish Duplicate Photos with VisiPic

  • Trying to format drive fails

    - by david
    since I will be doing an internship for which i need to use Windows software, I have decided to ruin my day trying to remove my Ubuntu 12.04, install Win XP SP3 (since the DualBoot theme from ubuntu suggests to first install Windows and then Ubuntu, for problems with the bootloader if you do it the other way around) and then reinstall Ubuntu 12.04 since I would like to keep using it as my primary operating system, using WinXP exclusively for the internship. Other than that, I would like to have a partition for the data, which can be used by both Ubuntu and Windows. So now, I have used the disk utility run from an ubuntu-live cd to format my drive with Master Boot Record (being conscious of the fact that this way I will lose all my data, which I have saved on an external drive before, and that my Ubuntu won't work anymore afterwards), creating partitions for Windows (NTFS), personal data (FAT, since as far as I know both Ubuntu and Windows can deal with this), a Swap partition for Linux, and one partition for Ubuntu (ext4); trying to install Win XP from cd gives me a blue screen, which stops the setup and telling me to remove all recently installed drives and to run CHKDSK. So I thought, that maybe Windows doesn't like pre-partitioned drives for its installation and thus I need to re-format my hard drive in order to have a completely "new" drive, which I can then, during the Windows-installation, partition in order to create the partitions I need. Trying to do this, though, the disk-utility run from the live-CD gives me this warning: Error creating partition table: helper exited with exit code 1: In part_create_partition_table: device_file=/dev/sda, scheme=0 got it got disk committed to disk BLKRRPART ioctl failed for /dev/sda: Device or resource busy I do not understand why it tells me that the hard-drive is busy, because, as stated above, I am doing all this from a live-CD. Thus, my questions are: How can I resolve the error given by the disk utility? Does it make sense to use four partitions in the way mentioned above? And if not so, which partitions should I create? Can I, theoretically, partition my drive from an Ubuntu live-cd in order to create the partitions I want and to install first Windows and then Ubuntu? Thanks for any help, David

  • Problems with both LightDM and GDM using DisplayLink USB monitor

    - by Austin
    When I use LightDM, it will auto-login to desktop just fine. The only problem is Compiz doesn't work, and menus don't work. I can't right-click the desktop, and I can't select program menus in the top bar (I.e clicking "File" does nothing). When I use GDM, I only get a blank blue screen and the mouse cursor. I can't Ctrl+Alt+Backspace to restart, but I can Ctrl+Alt+F1 and Ctrl+Alt+F7 to switch modes. I don't think it's auto-logging me in, but I'm not sure. It plays the login screen noise. Will update with more information when I get home! EDIT: Okay, so I did a fresh install, just to ensure I hadn't borked something playing in the console. I reconfigured my setup as I did before, with the same results. Here's what I followed. The only difference is that instead of setting "vga=normal nomodeset" I set "GRUB_GFXPAYLOAD_LINUX = text". Also I only have the DisplayLink monitor configured in my xorg.conf file. At this point I'm using the open radeon driver, although I used the proprietary ati driver before. I'm not sure if I'm having a problem with: - X configuration - Graphics driver - DisplayLink driver - Unity - LightDM - Compiz - Or something else The resolution of the monitor is 800x480, 16bit. I tried setting a larger virtual resolution of 1200x720 (because the real resolution is lower than the recommended resolution), but it causes Ubuntu to boot into low graphics mode. When I get home I'm going to install the fglrx driver and see if it enables virtual resolutions, which may further enable my window manager to function properly.

  • How to start gnome-shell?

  • JQGrdi PDF Export

    - by thanigai
    Originally posted on: http://geekswithblogs.net/thanigai/archive/2013/06/17/jqgrdi-pdf-export.aspxJQGrid PDF Export The aim of this article is to address the PDF export from client side grid frameworks. The solution is done using the ASP.Net MVC 4 and VisualStudio 2012. The article assumes the developer to have a fair amount of knowledge on ASP.Net MVC and C#. Tools Used Visual Studio 2012 ASP.Net MVC 4 Nuget Package Manager JQGrid  is one of the client grid framework built on top of the JQuery framework. It helps in building a beautiful grid with paging, sorting and exiting options. There are also other features available as extension plugins and developers can write their own if needed. You can download the JQgrid from the  JQGrid  homepage or as NUget package. I have given below the command to download the JQGrid through the package manager console. From the tools menu select “Library Package Manager” and then select “Package Manager Console”. I have given the screenshot below. This command will pull down the latest JQGrid package and adds them in the script folder. Once the script is downloaded and referenced in the project update the bundleconfig file to add the script reference in the pages. Bundleconfig can be found in the  App_Start  folder in the project structure. bundles .Add (newStyleBundle(“~/Content/jqgrid”).Include (“~/Content/ui.jqgrid.css”)); bundles.Add( newScriptBundle( “~/bundles/jquerygrid”) .Include( “~/Scripts/jqGrid/jquery.jqGrid*”)); Once added the config’s refer the bundles to the Views/Shared/LayoutPage.cshtml. Add the following lines to the head section of the page. @Styles.Render(“~/Content/jqgrid”) Add the following lines to the end of the page before html close tags. @Scripts.Render(“~/bundles/jquery”) @Scripts.Render(“~/bundles/jqueryui”) @Scripts.Render(“ ~/bundles/jquerygrid”)              That’s all to be done from the view perspective. Once these steps are done the developer can start coding for the JQGrid. In this example we will modify the HomeController for the demo. The index action will be the default action. We will add an argument for this index action. Let it be nullable bool. It’s just to mark the pdf request. In the Index.cshtml we will add a table tag with an id “ gridTable “. We will use this table for making the grid. Since JQGrid is an extension for the JQUery we will initialize the grid setting at the  script  section of the page. This script section is marked at the end of the page to improve performance. The script section is placed just below the bundle reference for JQuery and JQueryUI. This is the one of improvement factors from “ why slow” provided by yahoo. < tableid=“gridTable”class=“scroll”></ table> < inputtype=“button”value=“Export PDF”onclick=“exportPDF();“/>  @section scripts { <scripttype=“text/javascript”> $(document).ready(function(){$(“#gridTable”).jqGrid({datatype:“json”,url:‘@Url.Action(“GetCustomerDetails”)‘,mtype:‘GET’,colNames:["CustomerID","CustomerName","Location","PrimaryBusiness"],colModel:[{name:"CustomerID",width:40,index:"CustomerID",align:"center"},{name:"CustomerName",width:40,index:"CustomerName",align:"center"},{name:"Location",width:40,index:"Location",align:"center"},{name:"PrimaryBusiness",width:40,index:"PrimaryBusiness",align:"center"},],height:250,autowidth:true,sortorder:“asc”,rowNum:10,rowList:[5,10,15,20],sortname:“CustomerID”,viewrecords:true});});  function exportPDF (){ document . location = ‘ @ Url . Action ( “Index” ) ?pdf=true’ ; } </ script >  } The exportPDF methos just sets the document location to the Index action method with PDF Boolean as true just to mark for download PDF. An inmemory list collection is used for demo purpose. The  GetCustomerDetailsmethod is the server side action method that will provide the data as JSON list. We will see the method explanation below. [ HttpGet] publicJsonResultGetCustomerDetails(){ varresult=new { total=1, page=1, records=customerList.Count(), rows=( customerList.Select( e=>new { id=e.CustomerID, cell=newstring[]{ e.CustomerID.ToString(), e.CustomerName, e.Location, e.PrimaryBusiness}})) .ToArray()}; returnJson( result,  JsonRequestBehavior.AllowGet); }   JQGrid can understand the response data from server in certain format. The server method shown above is taking care of formatting the response so that JQGrid understand the data properly. The response data should contain totalpages, current page, full record count, rows of data with id and remaining columns as string array. The response is built using an anonymous object and will be sent as a MVC JsonResult. Since we are using HttpGet it’s better to mark the attribute as HttpGet and also the JSON requestbehavious as AllowGet. The inmemory list is initialized in the homecontroller constructor for reference. Public class HomeController : Controller{ private readonly Ilist < CustomerViewModel > customerList ; public HomeController (){ customerList=newList<CustomerViewModel>() { newCustomerViewModel{ CustomerID=100, CustomerName=“Sundar”, Location=“Chennai”, PrimaryBusiness=“Teacing”}, newCustomerViewModel{ CustomerID=101, CustomerName=“Sudhagar”, Location=“Chennai”, PrimaryBusiness=“Software”}, newCustomerViewModel{ CustomerID=102, CustomerName=“Thivagar”, Location=“China”, PrimaryBusiness=“SAP”}, }; }  publicActionResultIndex( bool?pdf){ if ( !pdf.HasValue){ returnView( customerList);} else{ stringfilePath=Server.MapPath( “Content”)  +“Sample.pdf”; ExportPDF( customerList,  new string[]{  “CustomerID”,  “CustomerName”,  “Location”,  “PrimaryBusiness” },  filePath); return File ( filePath ,  “application/pdf” , “list.pdf” ); }}   The index actionmethod has a Boolean argument named “pdf”. It’s used to indicate for PDF download. When the application starts this method is first hit for initial page request. For PDF operation a filename is generated and then sent to the  ExportPDF  method which will take care of generating the PDF from the datasource. The  ExportPDF method is listed below.  Private static void ExportPDF<TSource>(IList<TSource>customerList,string [] columns, string filePath){ FontheaderFont=FontFactory.GetFont( “Verdana”,  10,  Color.WHITE); Fontrowfont=FontFactory.GetFont( “Verdana”,  10,  Color.BLUE); Documentdocument=newDocument( PageSize.A4);  PdfWriter writer = PdfWriter . GetInstance ( document ,  new FileStream ( filePath ,  FileMode . OpenOrCreate )); document.Open(); PdfPTabletable=newPdfPTable( columns.Length); foreach ( varcolumnincolumns){ PdfPCellcell=newPdfPCell( newPhrase( column,  headerFont)); cell.BackgroundColor=Color.BLACK; table.AddCell( cell); }  foreach  ( var item in customerList ) { foreach ( varcolumnincolumns){ stringvalue=item.GetType() .GetProperty( column) .GetValue( item) .ToString(); PdfPCellcell5=newPdfPCell( newPhrase( value,  rowfont)); table.AddCell( cell5); } }  document.Add( table); document.Close(); }   iTextSharp is one of the pioneer in PDF export. It’s an opensource library readily available as NUget library. This command will pulldown latest available library. I am using the version 4.1.2.0. The latest version may have changed. There are three main things in this library. Document This is the document class which takes care of creating the document sheet with particular size. We have used A4 size. There is also an option to define the rectangle size. This document instance will be further used in next methods for reference. PdfWriter PdfWriter takes the filename and the document as the reference. This class enables the document class to generate the PDF content and save them in a file. Font Using the FONT class the developer can control the font features. Since I need a nice looking font I am giving the Verdana font. Following this PdfPTable and PdfPCell are used for generating the normal table layout. We have created two set of fonts for header and footer. Font headerFont=FontFactory .GetFont(“Verdana”, 10, Color .WHITE); Font rowfont=FontFactory .GetFont(“Verdana”, 10, Color .BLUE);   We are getting the header columns as string array. Columns argument array is looped and header is generated. We are using the headerfont for this purpose. PdfWriter writer=PdfWriter .GetInstance(document, newFileStream (filePath, FileMode.OpenOrCreate)); document.Open(); PdfPTabletable=newPdfPTable( columns.Length); foreach ( varcolumnincolumns){ PdfPCellcell=newPdfPCell( newPhrase( column,  headerFont)); cell.BackgroundColor=Color.BLACK; table.AddCell( cell); }   Then reflection is used to generate the row wise details and form the grid. foreach  (var item in customerList){ foreach ( varcolumnincolumns) { stringvalue=item.GetType() .GetProperty( column) .GetValue( item) .ToString(); PdfPCellcell5=newPdfPCell( newPhrase( value,  rowfont)); table.AddCell( cell5); } } document . Add ( table ); document . Close ();   Once the process id done the pdf table is added to the document and document is closed to write all the changes to the filepath given. Then the control moves to the controller which will take care of sending the response as a JSON result with a filename. If the file name is not given then the PDF will open in the same page otherwise a popup will open up asking whether to save the file or open file. Return File(filePath, “application/pdf”,“list.pdf”);   The final result screen is shown below. PDF file opened below to show the output. Conclusion: This is how the export pdf is done for JQGrid. The problem area that is addressed here is the clientside grid frameworks won’t support PDF’s export. In that time it’s better to have a fine grained control over the data and generated PDF. iTextSharp has helped us to achieve our goal.

  • Sharing A Stage: JDeveloper/ADF & NetBeans/Java EE 6?

    - by Geertjan
    A highlight for me during last week's Oracle Developer Day in Romania (which I blogged about here) was meeting Jernej Kaše (who is from Slovenia, just like my philosopher hero Slavoj Žižek), who is an Oracle Fusion Middleware evangelist. At the conference, while I was presenting NetBeans and Java EE 6 in one room, Jernej was presenting JDeveloper and ADF in another room. The application he created looks as follows, i.e., a realistic CRUD app, with a master/detail view, a search feature, and validation: In a conversation during a break, we started imagining a scenario where the two of us would be on the same stage, taking turns talking about NetBeans/Java EE and JDeveloper/ADF. In that way, attendees at a conference wouldn't need to choose which of the two topics to attend, because they'd be handled in the same session, with the session possibly being longer so that sufficient time could be spent on the respective technologies. (The JDeveloper/ADF session would then not be competing with the NetBeans/Java EE 6 session, since they'd be handled simultaneously.) The session would focus on the similarities/differences between the two respective tools/solutions, which would be extremely interesting and also unique. The crucial question in making this kind of co-presentation possible is whether (and how quickly) an application such as the one created above with JDeveloper/ADF could be created with NetBeans/Java EE 6. The NetBeans/Java EE 6 story is extremely strong on the model and controler levels, but less strong on the view layer. Though there are choices between using PrimeFaces, RichFaces, and IceFaces, that support is quite limited in the absence of a visual designer or of other specific tools (e.g., code generators to generate snippets of PrimeFaces) connected to JSF component libraries. However, it so happens that in recent months we at NetBeans have established really good connections with the PrimeFaces team (more about that another time). So I asked them what it would take to write the above UI in PrimeFaces. The PrimeFaces team were very helpful. They sent me the following screenshot, which is of the UI they created in PrimeFaces, reproducing the ADF screenshot above: Of course, the above is purely the UI layer, there's no EJB and entity classes and data connection hooked into it yet. However, this is the Facelets file that the PrimeFaces team sent me, i.e., using the PrimeFaces component library, that produces the above result: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:p="http://primefaces.org/ui"> <f:view> <h:head> <style type="text/css"> .alignRight { text-align: right; } .alignLeft { text-align: left; } .alignTop { vertical-align: top; } .ui-validation-required { color: red; font-size: 14px; margin-right: 5px; position: relative; vertical-align: top; } .ui-selectonemenu .ui-selectonemenu-trigger .ui-icon { margin-top: 7px !important; } </style> </h:head> <h:body> <h:form prependId="false" id="form"> <p:panel header="Employees"> <h:panelGrid columns="4" id="searchPanel"> Search <p:selectOneMenu> <f:selectItem itemLabel="FirstName" itemValue="FirstName" /> <f:selectItem itemLabel="LastName" itemValue="LastName" /> <f:selectItem itemLabel="Email" itemValue="Email" /> <f:selectItem itemLabel="PhoneNumber" itemValue="PhoneNumber" /> </p:selectOneMenu> <p:inputText /> <p:commandLink process="searchPanel" update="@form"> <h:graphicImage name="next.gif" library="img" /> </p:commandLink> </h:panelGrid> <h:panelGrid columns="3" columnClasses="alignTop,,alignTop" style="width:90%;margin-left:10%"> <h:panelGrid columns="2" columnClasses="alignRight,alignLeft"> <h:outputLabel for="firstName">FirstName</h:outputLabel> <p:inputText id="firstName" /> <h:outputLabel for="lastName"> <sup class="ui-validation-required">*</sup>LastName </h:outputLabel> <p:inputText id="lastName" style="width:250px;" /> <h:outputLabel for="email"> <sup class="ui-validation-required">*</sup>Email </h:outputLabel> <p:inputText id="email" style="width:250px;" /> <h:outputLabel for="phoneNumber" value="PhoneNumber" /> <p:inputMask id="phoneNumber" mask="999.999.9999" /> <h:outputLabel for="hireDate"> <sup class="ui-validation-required">*</sup>HireDate</h:outputLabel> <p:calendar id="hireDate" pattern="MM/dd/yyyy" showOn="button" /> </h:panelGrid> <p:outputPanel style="min-width:40px;" /> <h:panelGrid columns="2" columnClasses="alignRight,alignLeft"> <h:outputLabel for="jobId"> <sup class="ui-validation-required">*</sup>JobId </h:outputLabel> <p:selectOneMenu id="jobId" > <f:selectItem itemLabel="Administration Vice President" itemValue="Administration Vice President" /> <f:selectItem itemLabel="Vice President" itemValue="Vice President" /> </p:selectOneMenu> <h:outputLabel for="salary">Salary</h:outputLabel> <p:inputText id="salary" styleClass="alignRight" /> <h:outputLabel for="commissionPct">CommissionPct</h:outputLabel> <p:inputText id="commissionPct" style="width:30px;" maxlength="3" /> <h:outputLabel for="manager">ManagerId</h:outputLabel> <p:selectOneMenu id="manager"> <f:selectItem itemLabel="Steven King" itemValue="Steven" /> <f:selectItem itemLabel="Michael Cook" itemValue="Michael" /> <f:selectItem itemLabel="John Benjamin" itemValue="John" /> <f:selectItem itemLabel="Dav Glass" itemValue="Dav" /> </p:selectOneMenu> <h:outputLabel for="department">DepartmentId</h:outputLabel> <p:selectOneMenu id="department"> <f:selectItem itemLabel="90" itemValue="90" /> <f:selectItem itemLabel="80" itemValue="80" /> <f:selectItem itemLabel="70" itemValue="70" /> <f:selectItem itemLabel="60" itemValue="60" /> <f:selectItem itemLabel="50" itemValue="50" /> <f:selectItem itemLabel="40" itemValue="40" /> <f:selectItem itemLabel="30" itemValue="30" /> <f:selectItem itemLabel="20" itemValue="20" /> </p:selectOneMenu> </h:panelGrid> </h:panelGrid> <p:outputPanel id="buttonPanel"> <p:commandButton value="First" process="@this" update="@form" /> <p:commandButton value="Previous" process="@this" update="@form" style="margin-left:15px;" /> <p:commandButton value="Next" process="@this" update="@form" style="margin-left:15px;" /> <p:commandButton value="Last" process="@this" update="@form" style="margin-left:15px;" /> </p:outputPanel> <p:tabView style="margin-top:25px"> <p:tab title="Job History"> <p:dataTable var="history"> <p:column headerText="StartDate"> <h:outputText value="#{history.startDate}"> <f:convertDateTime pattern="MM/dd/yyyy" /> </h:outputText> </p:column> <p:column headerText="EndDate"> <h:outputText value="#{history.endDate}"> <f:convertDateTime pattern="MM/dd/yyyy" /> </h:outputText> </p:column> <p:column headerText="JobId"> <h:outputText value="#{history.jobId}" /> </p:column> <p:column headerText="DepartmentId"> <h:outputText value="#{history.departmentIdId}" /> </p:column> </p:dataTable> </p:tab> </p:tabView> </p:panel> </h:form> </h:body> </f:view> </html> Right now, NetBeans IDE only has code completion to create the above. So there's not much help for creating such a UI right now. I don't believe that a visual designer is mandatory to create the above. A few code generators and file templates could do the job too. And I'm looking forward to seeing those kinds of tools for PrimeFaces, as well as other JSF component libraries, appearing in NetBeans IDE in upcoming releases. A related option would be for the NetBeans generated CRUD app to include the option of having a master/detail view, as well as the option of having a search feature, i.e., the application generators would provide the option of having additional features typical in Java enterprise apps. In the absence of such tools, there still is room, I believe, for NetBeans/Java EE and JDeveloper/ADF sharing a stage at a conference. The above file would have been prepared up front and the presenter would state that fact. The UI layer is only one aspect of a Java EE 6 application, so that the presenter would have ample other features to show (i.e., the entity class generation, the tools for working with servlets, with session beans, etc) prior to getting to the point where the statement would be made: "On the UI layer, I have prepared this Facelets file, which I will now show you can be connected to the lower layers of the application as follows." At that point, the session beans could be hooked into the Facelets file, the file would be saved, the browser refreshed, and then the whole application would work exactly as the ADF application does. So, Jernej, let's share a stage soon!

  • Clipping polygons in XNA with stencil (not using spritebatch)

    - by Blau
    The problem... i'm drawing polygons, in this case boxes, and i want clip children polygons with its parent's client area. // Class Region public void Render(GraphicsDevice Device, Camera Camera) { int StencilLevel = 0; Device.Clear( ClearOptions.Stencil, Vector4.Zero, 0, StencilLevel ); Render( Device, Camera, StencilLevel ); } private void Render(GraphicsDevice Device, Camera Camera, int StencilLevel) { Device.SamplerStates[0] = this.SamplerState; Device.Textures[0] = this.Texture; Device.RasterizerState = RasterizerState.CullNone; Device.BlendState = BlendState.AlphaBlend; Device.DepthStencilState = DepthStencilState.Default; Effect.Prepare(this, Camera ); Device.DepthStencilState = GlobalContext.GraphicsStates.IncMask; Device.ReferenceStencil = StencilLevel; foreach ( EffectPass pass in Effect.Techniques[Technique].Passes ) { pass.Apply( ); Device.DrawUserIndexedPrimitives<VertexPositionColorTexture>( PrimitiveType.TriangleList, VertexData, 0, VertexData.Length, IndexData, 0, PrimitiveCount ); } foreach ( Region child in ChildrenRegions ) { child.Render( Device, Camera, StencilLevel + 1 ); } Effect.Prepare( this, Camera ); // This does not works Device.BlendState = GlobalContext.GraphicsStates.NoWriteColor; Device.DepthStencilState = GlobalContext.GraphicsStates.DecMask; Device.ReferenceStencil = StencilLevel; // This should be +1, but in that case the last drrawed is blue and overlap all foreach ( EffectPass pass in Effect.Techniques[Technique].Passes ) { pass.Apply( ); Device.DrawUserIndexedPrimitives<VertexPositionColorTexture>( PrimitiveType.TriangleList, VertexData, 0, VertexData.Length, IndexData, 0, PrimitiveCount ); } } public static class GraphicsStates { public static BlendState NoWriteColor = new BlendState( ) { ColorSourceBlend = Blend.One, AlphaSourceBlend = Blend.One, ColorDestinationBlend = Blend.InverseSourceAlpha, AlphaDestinationBlend = Blend.InverseSourceAlpha, ColorWriteChannels1 = ColorWriteChannels.None }; public static DepthStencilState IncMask = new DepthStencilState( ) { StencilEnable = true, StencilFunction = CompareFunction.Equal, StencilPass = StencilOperation.IncrementSaturation, }; public static DepthStencilState DecMask = new DepthStencilState( ) { StencilEnable = true, StencilFunction = CompareFunction.Equal, StencilPass = StencilOperation.DecrementSaturation, }; } How can achieve this? EDIT: I've just relized that the NoWriteColors.ColorWriteChannels1 should be NoWriteColors.ColorWriteChannels. :) Now it's clipping right. Any other approach?

  • Why I don't use SSIS checkpoint files

    - by jamiet
    In a recent discussion in regard to general ETL best practises the subject of checkpoint files as a means for package restartability came up and I stated that I was dead against using them. For anyone that may care, here is why: Configuring them is distinctly unintuitive (that's a matter of opinion but if you follow the link I'll wager that you will agree) they don't make any allowance for loop iterations they cannot store variables of type Object they are limited in ability. There are many scenarios where you may want to execute certain containers regardless of whether the package is started from a checkpoint file but the current usage model does not allow for this. they are ignored by eventhandlers, which wouldn't be so bad if there were a way to toggle this behaviour in certain scenarios they dont work properly I'll expand on the last bullet point. I have encountered situations where the behaviour for tasks executing concurrently is unpredictable. That is, sometimes the completion of a task that executes concurrently with a failed/failing task will make it into the checkpoint file and sometimes it won't. This is near-impossible to reproduce but it does happen as my good friend John Welch will hopefully concur (if he is reading). Is anyone out there making successful use of checkpoint files within SSIS? I would be interested in knowing about that if so. @Jamiet

  • Visual WebGui helps Dawsons put its Windows Forms HR system on the web

    - by Webgui
    Dawsons needed to upgrade their existing Windows Forms LAN human resources system to allow better and flexible access to the ever increasing data size as labor hire clients are demanding easy access to copies of tickets and licenses and etc. The company has some 30,000 applicants on file, but access to this data has been complex and limited with the current system. Therefore the IT department was asked to find a possible solutions that would allow creating a web based application while utilizing as much of the existing Windows Forms code as possible. Visual WebGui was found to be highly regarded in many frameworks comparisons so the team decided to give Visual WebGui a try. It didn’t take long for them to recognize that the Visual WebGui controls appear and react over the web the same as desktop controls. This and the fact that most of the code was directly ported which saved Dawsons hundreds of development hours are what make Visual WebGui so unique and productive. “My first impression of Visual WebGui was perhaps disbelief. Not being a seasoned Web programmer, I initially found it hard to accept so much functionality from a web based application. Also, the speed is exceptional” said John Sainsbury, Financial Controller of the Dawsons Group who added “Since working with Visual WebGui, I have showcased parts of the application to our major clients, some of whom use SAP portals, and they are amazed.” The result was so satisfying that the company is now looking to produce a mobile version for accessing the labor pool on the go. “By removing the barriers of the local network, Visual WebGui has changed how we can do business” said Lloyd Everist, General Manager Dawsons Group.

  • How can I move along an angled collision at a constant speed?

    - by Raven Dreamer
    I have, for all intents and purposes, a Triangle class that objects in my scene can collide with (In actuality, the right side of a parallelogram). My collision detection and resolution code works fine for the purposes of preventing a gameobject from entering into the space of the Triangle, instead directing the movement along the edge. The trouble is, the maximum speed along the x and y axis is not equivalent in my game, and moving along the Y axis (up or down) should take twice as long as an equivalent distance along the X axis (left or right). Unfortunately, these speeds apply to the collision resolution too, and movement along the blue path above progresses twice as fast. What can I do in my collision resolution to make sure that the speedlimit for Y axis movement is obeyed in the latter case? Collision Resolution for this case below (vecInput and velocity are the position and velocity vectors of the game object): // y = mx+c lowY = 2*vecInput.x + parag.rightYIntercept ; ... else { // y = mx+c // vecInput.y = 2(x) + RightYIntercept // (vecInput.y - RightYIntercept) / 2 = x; //if velocity.Y (positive) greater than velocity.X (negative) //pushing from bottom, so push right. if(velocity.y > -1*velocity.x) { vecInput = new Vector2((vecInput.y - parag.rightYIntercept)/2, vecInput.y); Debug.Log("adjusted rightwards"); } else { vecInput = new Vector2( vecInput.x, lowY); Debug.Log("adjusted downwards"); } }

  • Why doesn't Unity's OnCollisionEnter give me surface normals, and what's the most reliable way to get them?

    - by michael.bartnett
    Unity's on collision event gives you a Collision object that gives you some information about the collision that happened (including a list of ContactPoints with hit normals). But what you don't get is surface normals for the collider that you hit. Here's a screenshot to illustrate. The red line is from ContactPoint.normal and the blue line is from RaycastHit.normal. Is this an instance of Unity hiding information to provide a simplified API? Or do standard 3D realtime collision detection techniques just not collect this information? And for the second part of the question, what's a surefire and relatively efficient way to get a surface normal for a collision? I know that raycasting gives you surface normals, but it seems I need to do several raycasts to accomplish this for all scenarios (maybe a contact point/normal combination misses the collider on the first cast, or maybe you need to do some average of all the contact points' normals to get the best result). My current method: Back up the Collision.contacts[0].point along its hit normal Raycast down the negated hit normal for float.MaxValue, on Collision.collider If that fails, repeat steps 1 and 2 with the non-negated normal If that fails, try steps 1 to 3 with Collision.contacts[1] Repeat 4 until successful or until all contact points exhausted. Give up, return Vector3.zero. This seems to catch everything, but all those raycasts make me queasy, and I'm not sure how to test that this works for enough cases. Is there a better way?
