  • Why is this mod_rewrite RewriteRule directive not working in the .htaccess file?

    - by morgant
    I've got a site that was hosted on a linux el cheapo hosting service that I'm migrating to my Mac OS X 10.5 Leopard Server server running Apache 2.2.8 & PHP 5.2.5 w/rewrite_module enabled and AllowOverride All, but I'm running into an issue with the following lines in the .htaccess file: RewriteEngine On #RewriteRule ^view/([^/\.]+)/?$ /view.php?item=$1 [L] #RewriteRule ^order/([^/\.]+)/?$ /order.php?item=$1 [L] RewriteRule ^category/([^/\.]+)/?$ /category.php?category=$1 [L] As you can see, I've commented out the RewriteRule directives for /view/ and /order/, so I'm only dealing with /category/. When I attempt to load http://domain.tld/category/2/ it runs category.php (I've added debug code to confirm), but $_SERVER['REQUEST_URI'] comes through as /category/2/ and $_GET['category'] comes through as empty. I'm usually fine with troubleshooting .htaccess files and mod_rewrite directives, but this one's got me stumped for some reason. Update: I followed Josh's suggestion and here's the what's dumped to mod_rewrite.log when I try to access http://domain.tld/category/2/: 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (2) init rewrite engine with requested uri /category/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) applying pattern '.*' to uri '/category/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (1) pass through /category/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] add path info postfix: /Library/WebServer/Documents/tld.domain.www/category.php -> /Library/WebServer/Documents/tld.domain.www/category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] strip per-dir prefix: /Library/WebServer/Documents/tld.domain.www/category.php/13 -> category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] applying pattern '^category/([^/\.]+)/?$' to uri 'category.php/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (1) [perdir /Library/WebServer/Documents/tld.domain.www/] pass through /Library/WebServer/Documents/tld.domain.www/category.php 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] add path info postfix: /Library/WebServer/Documents/tld.domain.www/category.php -> /Library/WebServer/Documents/tld.domain.www/category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] strip per-dir prefix: /Library/WebServer/Documents/tld.domain.www/category.php/13 -> category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] applying pattern '^category/([^/\.]+)/?$' to uri 'category.php/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (1) [perdir /Library/WebServer/Documents/tld.domain.www/] pass through /Library/WebServer/Documents/tld.domain.www/category.php 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (2) init rewrite engine with requested uri /13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (3) applying pattern '.*' to uri '/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (1) pass through /13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] strip per-dir prefix: /Library/WebServer/Documents/tld.domain.www/13 -> 13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] applying pattern '^category/([^/\.]+)/?$' to uri '13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (1) [perdir /Library/WebServer/Documents/tld.domain.www/] pass through /Library/WebServer/Documents/tld.domain.www/13

  • SSH connection times out

    - by mark
    Given: vm - a WinXPsp3 virtual machine hosted by a Win7sp1 physical machine alice is the user on vm srv - a Win2008R2sp1 server bob is the user on srv quake - a linux server mark is the user on quake Both vm and srv have the same new installation of cygwin (1.7.9) and openssh. Firewall service is disabled on vm (and its host) and on srv All the machines can be pinged from all the machines. ssh mark@quake works OK from both vm and srv. ssh bob@srv works OK from both quake and vm. ssh alice@vm works on the vm itself only, but it fails on the other two machines: alice@vm ~ $ ssh alice@vm alice@vm's password: Last login: Tue Oct 25 23:42:09 2011 from vm.shunra.net [mark@Quake ~]$ ssh -vvv alice@vm OpenSSH_4.3p2, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to vm [172.30.2.60] port 22. debug1: connect to address 172.30.2.60 port 22: Connection timed out ssh: connect to host vm port 22: Connection timed out bob@Srv ~ $ ssh -vvv alice@vm OpenSSH_5.9p1, OpenSSL 0.9.8r 8 Feb 2011 debug1: Reading configuration data /etc/ssh_config debug2: ssh_connect: needpriv 0 debug1: Connecting to vm [172.30.2.60] port 22. debug1: connect to address 172.30.2.60 port 22: Connection timed out ssh: connect to host vm port 22: Connection timed out I used ssh-host-config both on vm and srv to configure the ssh to run as a windows service. Besides that I did nothing else. Can anyone help me troubleshoot this issue? Thank you very much. EDIT The virtual machine software is VMWare Workstation 7.1.4. I think the problem is in its settings, but I have no idea where exactly. The Network Adapter is set to Bridged. EDIT2 All the machines are located in the company lab, I think all of them are on the same segment, but I may be wrong. Below is the ipconfig /all output for each machine (skipping the linux server). I have deleted the Tunnel adapters to keep the output minimal. If anyone thinks they matter, do tell so and I will post them as well. In addition ping output is given to show that DNS is correct. Something else, may be relevant, may be not. Doing psexec to srv works OK, whereas to vm failes with Access Denied. srv: C:\Windows\system32>ipconfig /all Windows IP Configuration Host Name . . . . . . . . . . . . : srv Primary Dns Suffix . . .

  • Podcast Show Notes: Collaborate 10 Wrap-Up - Part 1

    - by Bob Rhubart
    OK, I know last week I promised you a program featuring Oracle ACE Directors Mike van Alst (IT-Eye) and Jordan Braunstein (TUSC) and The Definitive Guide to SOA: Oracle Service Bus author Jeff Davies. But things happen. In this case, what happened was Collaborate 10 in Las Vegas. Prior to the event I asked Oracle ACE Director and OAUG board member Floyd Teter to see if he could round up a couple of people at the event for an impromtu interview over Skype (I was here in Cleveland) to get their impressions of the event. Listen to Part 1 Floyd, armed with his brand new iPad, went above and beyond the call of duty. At the appointed hour, which turned out to be about hour after the close of Collaborate 10,  Floyd had gathered nine other people to join him in a meeting room somewhere in the Mandalay Bay Convention Center. Here’s the entire roster: Floyd Teter - Project Manager at Jet Propulsion Lab, OAUG Board Blog | Twitter | LinkedIn | Oracle Mix | Oracle ACE Profile Mark Rittman - EMEA Technical Director and Co-Founder, Rittman Mead,  ODTUG Board Blog | Twitter | LinkedIn | Oracle Mix | Oracle ACE Profile Chet Justice - OBI Consultant at BI Wizards Blog | Twitter | LinkedIn | Oracle Mix | Oracle ACE Profile Elke Phelps - Oracle Applications DBA at Humana, OAUG SIG Chair Blog | LinkedIn | Oracle Mix | Book | Oracle ACE Profile Paul Jackson - Oracle Applications DBA at Humana Blog | LinkedIn | Oracle Mix | Book Srini Chavali - Enterprise Database & Tools Leader at Cummins, Inc Blog | LinkedIn | Oracle Mix Dave Ferguson – President, Oracle Applications Users Group LinkedIn | OAUG Profile John King - Owner, King Training Resources Website | LinkedIn | Oracle Mix Gavyn Whyte - Project Portfolio Manager at iFactory Consulting Blog | Twitter | LinkedIn | Oracle Mix John Nicholson - Channels & Alliances at Greenlight Technologies Website | LinkedIn Big thanks to Floyd for assembling the panelists and handling the on-scene MC/hosting duties.  Listen to Part 1 On a technical note, this discussion was conducted over Skype, using Floyd’s iPad, placed in the middle of the table.  During the call the audio was fantastic – the iPad did a remarkable job. Sadly, the Technology Gods were not smiling on me that day. The audio set-up that I tested successfully before the call failed to deliver when we first connected – I could hear the folks in Vegas, but they couldn’t hear me. A frantic, last-minute adjustment appeared to have fixed that problem, and the audio in my headphones from both sides of the conversation was loud and clear.  It wasn’t until I listened to the playback that I realized that something was wrong. So the audio for Vegas side of the discussion has about the same fidelity as a cell phone. It’s listenable, but disappointing when compared to what it sounded like during the discussion. Still, this was a one shot deal, and the roster of panelists and the resulting conversation was too good and too much fun to scrap just because of an unfortunate technical glitch.   Part 2 of this Collaborate 10 Wrap-Up will run next week. After that, it’s back on track with the previously scheduled program. So stay tuned: RSS del.icio.us Tags: oracle,otn,collborate 10,c10,oracle ace program,archbeat,arch2arch,oaug,odtug,las vegas Technorati Tags: oracle,otn,collborate 10,c10,oracle ace program,archbeat,arch2arch,oaug,odtug,las vegas

  • LSI SAS 9240-8i on Ubuntu 12.04 Hangs on Modprobe

    - by Francois Stark
    I used the LSI 9240-8i card on a smaller Intel motherboard with no problems in Ubuntu, with ZFS. However, we rebuilt the server to allow for more disks, using the ASROCK X79 Extreme 11 motherboard. It has 7 PCIe slots, and a LSI 2008 on-board. At first I thought the LSI 9240, when plugged in to PCIe, clashed with the on-board LSI 2008. Every time I plugged in the LSI 9240, modprobe would hang. Then I completely disabled the on-board LSI 2008, and the problem persisted. Last night it booted perfectly ONCE - all LSI cards and connected disks visible... However, all subsequent reboots failed. Both LSI cards' bios scans appear and they both see the disks connected to them, but Ubuntu modprobe hangs. Some selected dmesg lines, with both LSI cards enabled: [ 190.752100] megasas: [ 0]waiting for 1 commands to complete [ 195.772071] megasas: [ 5]waiting for 1 commands to complete [ 200.792079] megasas: [10]waiting for 1 commands to complete [ 205.812078] megasas: [15]waiting for 1 commands to complete [ 210.832037] megasas: [20]waiting for 1 commands to complete [ 215.852077] megasas: [25]waiting for 1 commands to complete [ 220.872072] megasas: [30]waiting for 1 commands to complete [ 225.892078] megasas: [35]waiting for 1 commands to complete [ 230.912086] megasas: [40]waiting for 1 commands to complete [ 235.932075] megasas: [45]waiting for 1 commands to complete [ 240.306157] usb 2-1.5: USB disconnect, device number 7 [ 240.952076] megasas: [50]waiting for 1 commands to complete [ 240.960034] INFO: task modprobe:233 blocked for more than 120 seconds.

  • From DBA to Data Analyst

    - by Denise McInerney
    Cross posted from the PASS Blog There is a lot changing in the data professional’s world these days. More data is being produced and stored. More enterprises are trying to use that data to improve their products and services and understand their customers better. More data platforms and tools seem to be crowding the market. For a traditional DBA this can be a confusing and perhaps unsettling time. It’s also a time that offers great opportunity for career growth. I speak from personal experience. We sometimes refer to the “accidental DBA”, the person who finds herself suddenly responsible for managing the database because she has some other technical skills. While it was not accidental, six months ago I was unexpectedly offered a chance to transition out of my DBA role and become a data analyst. I have since come to view this offer as a gift, though at the time I wasn’t quite sure what to do with it. Throughout my DBA career I’ve gotten support from my PASS friends and colleagues and they were the first ones I turned to for counsel about this new situation. Everyone was encouraging and I received two pieces of valuable advice: first, leverage what I already know about data and second, work to understand the business’ needs. Bringing the power of data to bear to solve business problems is really the heart of the job. The challenge is figuring out how to do that. PASS had been the source of much of my technical training as a DBA, so I naturally started there to begin my Business Intelligence education. Once again the Virtual Chapter webinars, local chapter meetings and SQL Saturdays have been invaluable. I work in a large company where we are fortunate to have some very talented data scientists and analysts. These colleagues have been generous with their time and advice. I also took a statistics class through Coursera where I got a refresher in statistics and an introduction to the R programming language. And that’s not the end of the free resources available to someone wanting to acquire new skills. There are many knowledgeable Business Intelligence and Analytics professionals who teach through their blogs. Every day I can learn something new from one of these experts. Sometimes we plan our next career move and sometimes it just happens. Either way a database professional who follows industry developments and acquires new skills will be better prepared when change comes. Take the opportunity to learn something about the changing data landscape and attend a Business Intelligence, Business Analytics or Big Data Virtual Chapter meeting. And if you are moving into this new world of data consider attending the PASS Business Analytics Conference in April where you can meet and learn from those who are already on that road. It’s been said that “the only thing constant is change.” That’s never been more true for the data professional than it is today. But if you are someone who loves data and grasps its potential you are in the right place at the right time.

  • Business School graduate joins Oracle

    - by jessica.ebbelaar(at)oracle.com
    My name is Mathias, I work as an Applications Inside Sales Rep for the French market, and I’d like to give you a brief snapshot of my experience at Oracle. First things first, how did you hear about Oracle? Where have you seen the sharp and recognizable red logo? Was it in Charles de Gaulle Airport when your eyes crossed the 20-metre banner with a picture of a strange big machine in the middle? Was it through reading the Forbes 10 top IT companies worldwide ranking? Or is it because IT is your thing and you cannot but know one of the “big four”? Meeting with a Grenoble Alumnus My story is a little different. My plan was to work in sales, in the IT industry. I had heard about Oracle, but my opinion at the time was that this kind of multinational company was way out of reach for a young graduate, even with high enthusiasm and great excitement to be (finally) on the job market. So, I was really surprised when I had an interesting conversation with a top alumnus of my business school. We were at the Grenoble Ecole de Management graduation ceremony (our graduation!), and before the party got really started, I got to chat with her. She told me of the great experience she was getting by living and working in Dublin. She had already figured it all out: “you work with another 100 young people from 10 different nationalities across Europe, you can be based in Dublin, but then once you work really hard you can move to Malaga Spain or other BUs around the world, you can work with different lines of business and learn about new “techy” and business oriented products, move to the field in your home country or elsewhere, etc.” What, what, what? Moving around Europe, trained by the best sales coaches in the world, acquiring strong IT knowledge and getting on board with one of fastest-growing and most watched companies in the world? Well, I was in. The next day (OK, 3 days after, the time to recover), I sent her my CV, and 3 months later I started as a Business Development Consultant at Oracle in Dublin, representing the latest cloud based CRM across the French market. That was 15 months ago. Since then, I moved line of business twice, I’m always learning new things and working with different and senior stakeholders; I have attended hundreds of hours of sales and product training (priceless when you come from a business background); I passed the Dublin Institute of Technology Sales Certification through different trainings given onsite within Oracle; I’ve led projects based around social media and I’ve gotten involved within various sales deals going on my market. Despite all of these great things, two will remain in my spirit: the multiculturalism that I experience every day in the office, and the American style of management - more direct and open than what you can find in “regular French companies”. Sales Progression Board In May 2012, I passed what we call a ‘Sales Progression Board’ to be promoted to an Inside Sales position. I am now in charge of generating revenue through the sale of Oracle applications on my specific territory. Always keeping in my mind my personal ambition: going to the field one day. Interested to join Oracle in the same role as Mathias? Visit http://campus.oracle.com.

  • Can't remove JPanel from JFrame while adding new class into it

    - by A.K.
    Basically, I have my Frame class, which instantiates all the properties for the JFrame, and draws a JLabel with an image (my title screen). Then I made a separate JPanel with a start button on it, and made a mouse listener that will allow me to remove these objects while adding in a new Board() class (Which paints the main game). *Note: The JLabel is SEPARATE from the JPanel, but it still gets moved to the side by it. Problem: Whenever I click the button though, it only shows a little square of what I presume is my board class trying to run. Code below for the Frame Class: package OurPackage; //Made By A.K. 5/24/12 //Contains Frame. import java.awt.BorderLayout; import java.awt.Color; import java.awt.Container; import java.awt.Dimension; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.GridBagLayout; import java.awt.GridLayout; import java.awt.Image; import java.awt.Rectangle; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.KeyEvent; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import java.awt.event.MouseListener; import javax.swing.*; import javax.swing.plaf.basic.BasicOptionPaneUI.ButtonActionListener; public class Frame implements MouseListener { public static boolean StartGame = false; ImageIcon img = new ImageIcon(getClass().getResource("/Images/ActionJackTitle.png")); ImageIcon StartImg = new ImageIcon(getClass().getResource("/Images/JackStart.png")); public Image Title; JLabel TitleL = new JLabel(img); public JPanel panel = new JPanel(); JButton StartB = new JButton(StartImg); JFrame frm = new JFrame("Action-Packed Jack"); public Frame() { TitleL.setPreferredSize(new Dimension(1200, 420)); frm.add(TitleL); frm.setLayout(new GridBagLayout()); frm.add(panel); panel.setSize(new Dimension(220, 45)); panel.setLayout(new GridBagLayout ()); panel.add(StartB); StartB.addMouseListener(this); StartB.setPreferredSize(new Dimension(220, 45)); frm.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frm.setSize(1200, 420); frm.setVisible(true); frm.setResizable(false); frm.setLocationRelativeTo(null); } public static void main(String[] args) { new Frame(); } public void mouseClicked(MouseEvent e) { StartB.setContentAreaFilled(false); panel.remove(StartB); frm.remove(panel); frm.remove(TitleL); //frm.setLayout(null); frm.add(new Board()); //Add Game "Tiles" Or Content. x = 1200 frm.validate(); System.out.println("Hit!"); } @Override public void mouseEntered(MouseEvent arg0) { // TODO Auto-generated method stub } @Override public void mouseExited(MouseEvent arg0) { // TODO Auto-generated method stub } @Override public void mousePressed(MouseEvent arg0) { // TODO Auto-generated method stub } @Override public void mouseReleased(MouseEvent arg0) { // TODO Auto-generated method stub } }

  • Representing Mauritius in the 2013 Bench Games

    Only by chance I came across an interesting option for professionals and enthusiasts in IT, and quite honestly I can't even remember where I caught attention of Brainbench and their 2013 Bench Games event. But having access to 600+ free exams in a friendly international intellectual competition doesn't happen to be available every day. So, it was actually a no-brainer to sign up and browse through the various categories. Most interestingly, Brainbench is not only IT-related. They offer a vast variety of fields in their Test Center, like Languages and Communication, Office Skills, Management, Aptitude, etc., and it can be a little bit messy about how things are organised. Anyway, while browsing through their test offers I added a couple of exams to 'My Plan' which I would give a shot afterwards. Self-assessments Actually, I took the tests based on two major aspects: 'Fun Factor' and 'How good would I be in general'... Usually, you have to pay for any kind of exams and given this unique chance by Brainbench to simply train this kind of tests was already worth the time. Frankly speaking, the tests are very close to the ones you would be asked to do at Prometric or Pearson Vue, ie. Microsoft exams, etc. Go through a set of multiple choice questions in a given time frame. Most of the tests I did during the Bench Games were based on 40 questions, each with a maximum of 3 minutes to answer. Ergo, one test in maximum 2 hours - that sounds feasible, doesn't it? The Measure of Achievement While the 2013 Bench Games are considered a worldwide friendly competition of knowledge I was really eager to get other Mauritians attracted. Using various social media networks and community activities it all looked quite well at the beginning. Mauritius was listed on rank #19 of Most Certified Citizens and rank #10 of Most Master Level Certified Nation - not bad, not bad... Until... the next update of the Bench Games Leaderboard. The downwards trend seemed to be unstoppable and I couldn't understand why my results didn't show up on the Individual Leader Board. First of all, I passed exams that were not even listed and second, I had better results on some exams listed. After some further information from the organiser it turned out that my test transcript wasn't available to the public. Only then results are considered and counted in the competition. During that time, I actually managed to hold 3 test results on the Individuals... Other participants were merciless, eh, more successful than me, produced better test results than I did. But still I managed to stay on the final score board: An 'exotic' combination of exam, test result, country and person itself Representing Mauritius and the Visual FoxPro community in that fun event. And although I mainly develop in Visual FoxPro 9.0 SP2 and C# using .NET Framework from 2.0 to 4.5 since a couple of years I still managed to pass on Master Level. Hm, actually my Microsoft Certified Programmer (MCP) exams are dated back in June 2004 - more than 9 years ago... Look who got lucky... As described above I did a couple of exams as time allowed and without any preparations, but still I received the following mail notification: "Thank you for recently participating in our Bench Games event.  We wanted to inform you that you obtained a top score on our test(s) during this event, and as a result, will receive a free annual Brainbench subscription.  Your annual subscription will give you access to all our tests just like Bench Games, but for an entire year plus additional benefits!" -- Leader Board Notification from Brainbench Even fun activities get rewarded sometimes. Thanks to @Brainbench_com for the free annual subscription based on my passed 2013 Bench Games Master Level exam. It would be interesting to know about the total figures, especially to see how many citizens of Mauritius took part in this year's Bench Games. Anyway, I'm looking forward to be able to participate in other challenges like this in the future.

  • Why RenderTarget2D overwrites other objects when trying to put some text in a model?

    - by cad
    I am trying to draw an object composited by two cubes (A & B) (one on top of the other, but for now I have them a little bit more open). I am able to do it and this is the result. (Cube A is the blue and Cube B is the one with brown text that comes from a png texture) But I want to have any text as parameter in the cube B. I have tried what @alecnash suggested in his question, but for some reason when I try to draw cube B, cube A dissapears and everything turns purple. This is my draw code: public void Draw(GraphicsDevice graphicsDevice, SpriteBatch spriteBatch, Matrix viewMatrix, Matrix projectionMatrix) { graphicsDevice.BlendState = BlendState.Opaque; graphicsDevice.DepthStencilState = DepthStencilState.Default; graphicsDevice.RasterizerState = RasterizerState.CullCounterClockwise; graphicsDevice.SamplerStates[0] = SamplerState.LinearClamp; // CUBE A basicEffect.View = viewMatrix; basicEffect.Projection = projectionMatrix; basicEffect.World = Matrix.CreateTranslation(ModelPosition); basicEffect.VertexColorEnabled = true; foreach (EffectPass pass in basicEffect.CurrentTechnique.Passes) { pass.Apply(); drawCUBE_TOP(graphicsDevice); drawCUBE_Floor(graphicsDevice); DrawFullSquareStripesFront(graphicsDevice, _numStrips, Color.Red, Color.Blue, _levelPercentage); DrawFullSquareStripesLeft(graphicsDevice, _numStrips, Color.Red, Color.Blue, _levelPercentage); DrawFullSquareStripesRight(graphicsDevice, _numStrips, Color.Red, Color.Blue, _levelPercentage); DrawFullSquareStripesBack(graphicsDevice, _numStrips, Color.Red, Color.Blue, _levelPercentage); } // CUBE B // Set the World matrix which defines the position of the cube texturedCubeEffect.World = Matrix.CreateTranslation(ModelPosition); // Set the View matrix which defines the camera and what it's looking at texturedCubeEffect.View = viewMatrix; // Set the Projection matrix which defines how we see the scene (Field of view) texturedCubeEffect.Projection = projectionMatrix; // Enable textures on the Cube Effect. this is necessary to texture the model texturedCubeEffect.TextureEnabled = true; Texture2D a = SpriteFontTextToTexture(graphicsDevice, spriteBatch, arialFont, "TEST ", Color.Black, Color.GhostWhite); texturedCubeEffect.Texture = a; //texturedCubeEffect.Texture = cubeTexture; // Enable some pretty lights texturedCubeEffect.EnableDefaultLighting(); // apply the effect and render the cube foreach (EffectPass pass in texturedCubeEffect.CurrentTechnique.Passes) { pass.Apply(); cubeToDraw.RenderToDevice(graphicsDevice); } } private Texture2D SpriteFontTextToTexture(GraphicsDevice graphicsDevice, SpriteBatch spriteBatch, SpriteFont font, string text, Color backgroundColor, Color textColor) { Vector2 Size = font.MeasureString(text); RenderTarget2D renderTarget = new RenderTarget2D(graphicsDevice, (int)Size.X, (int)Size.Y); graphicsDevice.SetRenderTarget(renderTarget); graphicsDevice.Clear(Color.Transparent); spriteBatch.Begin(); //have to redo the ColorTexture //spriteBatch.Draw(ColorTexture.Create(graphicsDevice, 1024, 1024, backgroundColor), Vector2.Zero, Color.White); spriteBatch.DrawString(font, text, Vector2.Zero, textColor); spriteBatch.End(); graphicsDevice.SetRenderTarget(null); return renderTarget; } The way I generate texture with dynamic text is: Texture2D a = SpriteFontTextToTexture(graphicsDevice, spriteBatch, arialFont, "TEST ", Color.Black, Color.GhostWhite); After commenting several parts to see what caused the problem, it seems to be located in this line graphicsDevice.SetRenderTarget(renderTarget);

  • How to mix C++ Qt objects and Qt Jambi objects

    - by Dan
    Hi, I'm trying to combine some existing Qt code written in C++ with some code written in Java using Qt Jambi, but I'm not quite sure how to do it. I'm basically trying to acieve two things: Pass a QObject from C++ to Java using JNI Pass a Qt Jambi QObject from Java to C++ It looks like I can pass the pointer directly and then wrap it in QNativePointer on the Java side, but I can't figure out how to turn a QNativePointer back into the original object, wrapped by Qt Jambi. Eg: I can pass a QWidget* as a long to Java and then create a QNativePointer in Java, but how can I then construct a QWidget out of this? QJambiObject and QObject dont seem to have a "setNativePointer" method and I'm not sure how to convert it. In C++: QWidget* widget = ... jclass cls = env->FindClass("Test"); jmethodID mid = env->GetStaticMethodID(cls, "test", "(I)V"); env->CallStaticVoidMethod(cls, mid, int(widget)); In Java: public class Test { public static void test (int ptr) { QNativePointer pointer = new QNativePointer(QNativePointer.Type.Int); pointer.setIntValue(ptr); QWidget widget = ...

  • How to program a neural network for chess?

    - by marco92w
    Hello! I want to program a chess engine which learns to make good moves and win against other players. I've already coded a representation of the chess board and a function which outputs all possible moves. So I only need an evaluation function which says how good a given situation of the board is. Therefore, I would like to use an artificial neural network which should then evaluate a given position. The output should be a numerical value. The higher the value is, the better is the position for the white player. My approach is to build a network of 385 neurons: There are six unique chess pieces and 64 fields on the board. So for every field we take 6 neurons (1 for every piece). If there is a white piece, the input value is 1. If there is a black piece, the value is -1. And if there is no piece of that sort on that field, the value is 0. In addition to that there should be 1 neuron for the player to move. If it is White's turn, the input value is 1 and if it's Black's turn, the value is -1. I think that configuration of the neural network is quite good. But the main part is missing: How can I implement this neural network into a coding language (e.g. Delphi)? I think the weights for each neuron should be the same in the beginning. Depending on the result of a match, the weights should then be adjusted. But how? I think I should let 2 computer players (both using my engine) play against each other. If White wins, Black gets the feedback that its weights aren't good. So it would be great if you could help me implementing the neural network into a coding language (best would be Delphi, otherwise pseudo-code). Thanks in advance!

  • Tricky SQL query involving consecutive values

    - by Gabriel
    I need to perform a relatively easy to explain but (given my somewhat limited skills) hard to write SQL query. Assume we have a table similar to this one: exam_no | name | surname | result | date ---------+------+---------+--------+------------ 1 | John | Doe | PASS | 2012-01-01 1 | Ryan | Smith | FAIL | 2012-01-02 <-- 1 | Ann | Evans | PASS | 2012-01-03 1 | Mary | Lee | FAIL | 2012-01-04 ... | ... | ... | ... | ... 2 | John | Doe | FAIL | 2012-02-01 <-- 2 | Ryan | Smith | FAIL | 2012-02-02 2 | Ann | Evans | FAIL | 2012-02-03 2 | Mary | Lee | PASS | 2012-02-04 ... | ... | ... | ... | ... 3 | John | Doe | FAIL | 2012-03-01 3 | Ryan | Smith | FAIL | 2012-03-02 3 | Ann | Evans | PASS | 2012-03-03 3 | Mary | Lee | FAIL | 2012-03-04 <-- Note that exam_no and date aren't necessarily related as one might expect from the kind of example I chose. Now, the query that I need to do is as follows: From the latest exam (exam_no = 3) find all the students that have failed (John Doe, Ryan Smith and Mary Lee). For each of these students find the date of the first of the batch of consecutively failing exams. Another way to put it would be: for each of these students find the date of the first failing exam that comes after their last passing exam. (Look at the arrows in the table). The resulting table should be something like this: name | surname | date_since_failing ------+---------+-------------------- John | Doe | 2012-02-01 Ryan | Smith | 2012-01-02 Mary | Lee | 2012-01-04 Ann | Evans | 2012-02-03 How can I perform such a query? Thank you for your time.

  • Android Scoreloop, OpenFeint etc al

    - by theblitz
    I am looking to use one of the social networks in my Android program. Most important for me is the ability to build a continuous leadership board in which players move up and down depending their wins/loses to others. The idea is for players to challenge others head-to-head. The winner gains points and the loser loses points. Equally important, I want this feature to include the possibility to "charge" the player game coins. Scoreloop includes the possibility of challenges but they are there in order to win coins off other players. In other words, they are the means to the end. In my case I need it to be the other way around. The "ends" is to be higher in the leadership board and the "means" are to play others with coins. Scoreloop do have a continuos leadership board but it is not accessible from the program. I tried looking at OpenFeint but their site is a real mess. It is impossible to understand from there exactly what is and isn't available. I signed up and tried to add my program. I ended up adding it four times and cannot delete it!

  • Unit Testing - Validation of ViewModel ASP.NET MVC 2

    - by dean nolan
    I am currently unit testing a service that adds users to a repository. I am using dependency injection to test using a fake repository. The repository has a method CreateUser(User user) which just adds it to the database or in this case a List of Users. The logic for the creation is in the UserServices class. The application has a form for creating a user that requires some properties such as name and address. This is an MVC 2 app and I will be using the new validation using data annotations. This makes me wonder about a few things: 1) Should I annotate a POCO object that will map to the database? Or should I create a specific View Model that has these annotations and pass this data to the UserServices class? 2)Should the UserServicesClass also check this data? Would I best be constructing a Usr out of the ViewModel and passing this into the Service as a parameter? 3) The actual unit testing would depend on 2), I either populate a User object and pass that in, or I pass a large list of strings to the method CreateUser. Writing this out I get a basic idea that I should probably annotate the view model only, pass in a user (constructed by the view model if the data is valid) and also just construct the user in the unit test also. Is this the best way to go?

  • SQL Server Trouble with Rails

    - by Earlz
    Ok, I've been trying to get this to work like all day now and I'm barely any further from when I started. I'm trying to get Ruby On Rails to connect to SQL Server. I've installed unixODBC and configured it and FreeTDS and installed just about every Ruby gem relating to ODBC that exists. [earlz@earlzarch myproject]$ tsql -S AVP1 -U sa -P pass locale is "en_US.UTF-8" locale charset is "UTF-8" 1> quit [earlz@earlzarch myproject]$ isql AVP1 sa pass [ISQL]ERROR: Could not SQLConnect [earlz@earlzarch myproject]$ rake db:version (in /home/earlz/myproject) rake aborted! IM002 (0) [unixODBC][Driver Manager]Data source name not found, and no default driver specified (See full trace by running task with --trace) so, as you can see, tsql works, but not isql. What is the difference in the two that breaks it? /etc/odbc.ini [AVP1] Description = ODBC connection via FreeTDS Driver = TDS Servername = my.server UID = sa PWD = pass port = 1232 Database = mydatabase /etc/odbcinst.ini [TDS] Description = v0.6 with protocol v7.0 Driver = /usr/lib/libtdsodbc.so Setup = /usr/lib/libtdsS.so CPTimeout = CPReuse = FileUsage = 1 (and yes, I've made sure that the .so files exist) the relevant part in freetds.conf [AVP1] host = my.server port = 1232 tds version = 8.0 and finally, my database.yml development: adapter: sqlserver mode: odbc dsn: AVP1 username: sa password: pass Can anyone please help me before I pull all my hair out? I am using a 64 bit Arch Linux that is completely up to date.

  • Ajax/PHP contact form not able to send mail

    - by Steph
    The funny thing is it did work for one evening. I contacted my host, and they are saying there's no reason it should not be working. I have also attempted to test it in Firebug, but it seemed to be sending. And I specifically put the email address (hosted in my domain) on my email safe list, so that is not the culprit either. Would anyone here take a look at it for me? I'd be so grateful. In the header I have: <script type="text/javascript"> $(document).ready(function() { var options = { target: '#alert' }; $('#contactForm').ajaxForm(options); }); $.fn.clearForm = function() { return this.each(function() { var type = this.type, tag = this.tagName.toLowerCase(); if (tag == 'form') return $(':input',this).clearForm(); if (type == 'text' || type == 'password' || tag == 'textarea') this.value = ''; else if (type == 'checkbox' || type == 'radio') this.checked = false; else if (tag == 'select') this.selectedIndex = -1; }); }; </script> Here is the actual form: <form id="contactForm" method="post" action="sendmail.php"> <fieldset> <p>Email Me</p> <div id="fieldset_container"> <label for="name">Your Name:</label> <input type="text" name="name" id="name" /><br /><br /> <label for="email">Email:</label> <input type="text" name="email" id="email" /><br /><br /> <span style="display:none;"> <label for="last">Honeypot:</label> <input type="text" name="last" value="" id="last" /> </span><br /><br /> <label for="message">Comments &amp; Inquiries:</label> <textarea name="message" id="message" cols="" rows=""></textarea><br/> </div> <div id="submit_button"> <input type="submit" name="submit" id="submit" value="Send It" /> </div> </fieldset> </form> <div class="message"><div id="alert"></div></div> Here is the code from my validating page, sendmail.php: <?php // Who you want to recieve the emails from the form.

  • How can I get browser to prompt to save password?

    - by Eric
    Hey, I'm working on a web app that has a login dialog that works like this: User clicks "login" Login form HTML is loaded with AJAX and displayed in DIV on page User enters user/pass in fields and clicks submit. It's NOT a <form> -- user/pass are submitted via AJAX If user/pass are okay, page reloads with user logged in. If user/pass are bad, page does NOT reload but error message appears in DIV and user gets to try again. Here's the problem: the browser never offers the usual "Save this password? Yes / Never / Not Now" prompt that it does for other sites. I tried wrapping the <div> in <form> tags with "autocomplete='on'" but that made no difference. Is it possible to get the browser to offer to store the password without a major rework of my login flow? thanks Eric p.s. to add to my question, I'm definitely working with browers that store passwords, and I've never clicked "never for this site" ...this is a technical issue with the browser not detecting that it's a login form, not operator error :-)

  • Problem with JMX query of Coherence node MBeans visible in JConsole

    - by Quinn Taylor
    I'm using JMX to build a custom tool for monitoring remote Coherence clusters at work. I'm able to connect just fine and query MBeans directly, and I've acquired nearly all the information I need. However, I've run into a snag when trying to query MBeans for specific caches within a cluster, which is where I can find stats about total number of gets/puts, average time for each, etc. The MBeans I'm trying to access programatically are visible when I connect to the remote process using JConsole, and have names like this: Coherence:type=Cache,service=SequenceQueue,name=SEQ%GENERATOR,nodeId=1,tier=back It would make it more flexible if I can dynamically grab all type=Cache MBeans for a particular node ID without specifying all the caches. I'm trying to query them like this: QueryExp specifiedNodeId = Query.eq(Query.attr("nodeId"), Query.value(nodeId)); QueryExp typeIsCache = Query.eq(Query.attr("type"), Query.value("Cache")); QueryExp cacheNodes = Query.and(specifiedNodeId, typeIsCache); ObjectName coherence = new ObjectName("Coherence:*"); Set<ObjectName> cacheMBeans = mBeanServer.queryMBeans(coherence, cacheNodes); However, regardless of whether I use queryMBeans() or queryNames(), the query returns a Set containing... ...0 objects if I pass the arguments shown above ...0 objects if I pass null for the first argument ...all MBeans in the Coherence:* domain (112) if I pass null for the second argument ...every single MBean (128) if I pass null for both arguments The first two results are the unexpected ones, and suggest a problem in the QueryExp I'm passing, but I can't figure out what the problem is. I even tried just passing typeIsCache or specifiedNodeId for the second parameter (with either coherence or null as the first parameter) and I always get 0 results. I'm pretty green with JMX — any insight on what the problem is? (FYI, the monitoring tool will be run on Java 5, so things like JMX 2.0 won't help me at this point.)

  • What's the deal with Java's public fields?

    - by Annan
    I've been reading two articles (1)(2) on javaworld.com about how all class fields should be private and getter/setter methods are just as bad. An object should act on the data it has rather than allowing access to it. I'm currently working on a University assignment for Connect Four. In designing the program the Agents playing the Game need access to the Board's state (so they can decide what to move). They also need to pass this move to the Game so it can validate it as a legal move. And during deciding what to move pieces are grouped into Threats with a start and end Points. Board, Threat and Point objects don't really do anything. They are just there to store related data that can be accessed in a human readable way. At the start of design I was representing Points on the board as two element int arrays, however that got annoying when creating points or referencing components of them. So, the class: public class Point { public int x; public int y; public Point(int x, int y){ this.x = x; this.y = y; } } Perfect in every way I can think of. Except it breaks every rule I've learned. Have I sinned?

  • Flash Builder 4: Call main function from a component function

    - by hyper
    i try to make a login sistem in flex, and my app looks like this: i have a main.mxml. when the app loads, a function named "start" is called. it verifies if the user is logged in or not. if "true" the user is redirected to a dashboard, if "false", a component named login is loaded. my login.mxml component has 2 input boxes (user & pass) and a "Submit" button. when the button is pressed a function named "send_login" sends the user and the pass values to the server. My problem sounds like this: when i press the Submit button in my login component, after user and pass are sended... i want to call again the "start" function from my main.mxml to check again if the user is logged in or not... i need some kind of as2 "_root" this is how my code looks: main.mxml public function start():void { currentState="Start"; loginstatus(); } login.mxml private function send_login(event:Event):void { ... bla bla send user and pass.... scriptLoader.addEventListener(Event.COMPLETE, handleLoadSuccessful); } private function handleLoadSuccessful(evt:Event):void { trace("Data sent."); start(); <-- HERE i want to call the function from main.mxml } any help is welcomed!

  • APS.NET MVC Ajax: Passing a IList from the View to the Controller

    - by Bpimenta
    I need to pass the grid rows from the view to the controller using POST. The idea is to pass an IList of objects (people) that have the following structure: String Name String Address String ID I want to read the data from the JQGrid and pass it to the controller to fill the IList. I'm trying to build the data object to pass through the Ajax data parameter. Here is the Javascript code: $("#saveButton").click( function() { var returnData = '{'; var existingIDs = $('#listPeople').getDataIDs(); if (idsPeople.length > 0) { for (i=0;i<idsPeople.length;i++) { //Trying to build the obejct data ret = ret + '"people['+ i +'].Name":' $('#listPeople').getRowData(idsPeople[i]).Name + ','; ret = ret + '"people['+ i +'].Address":' $('#listPeople').getRowData(idsPeople[i]).Address+ ','; ret = ret + '"people['+ i +'].Id":' $('#listPeople').getRowData(idsPeople[i]).Id+ ','; //If it has more than one element if (idsPeople.length>1 && (i+1)<idsPeople.length) { ret = ret + ','; } } } ret = ret + '}'; My Ajax function for sending: var url_all = '<%=Url.Action("SaveData") %>; $.ajax({ type: "POST", url: url_all, data: ret, dataType: "json", success: function(){ alert("OK"); }, error: function(){ alert("Error: check SaveData"); } }); My controller: public ActionResult SaveData(IList<PeopleHeader> people){ // using debug to know if "people" variable has any values return Json(true); } The problem I'm getting is an error: "System.NotSupportedException: Fixed size collection", and no data is being delivered. I think my problem relies on creating the object... is there any simpler way of doing this procedure? Thanks in advance,

  • Passing data between ViewControllers versus doing local Fetch in each VC

    - by Tofrizer
    Hi All, I'm developing an iPhone app using Core Data and I'm looking for some general advice and recommendations on whether its acceptable to pass data between ViewControllers versus doing a local fetch in each ViewController as you navigate to it. Ordinarily I would say it all depends on various factors (e.g. performance etc) but the passing data approach is so prevalent in my app and I'm spooked by all the stories about Apple rejecting apps because of not conforming to their standard guidelines. So let me put another way -- is it non-standard to pass data between VC's? The reason I pass data so much is because each ViewController is just another view on to data present in my object model / graph. Once I have a handle on my first object in the first view controller (which I of course do have to fetch), I can use the existing object composition / relationships to drill down into the next level of detail into data and so I just pass these objects to the next VC. Separately, one possible downside with this passing-data-to-each-VC approach is I don't benefit from (what I perceive to be) the optimisation/benefits that NSFetchedResultsController provides in terms of efficient memory usage and section handling. My app is read-only but I do have one table with 5000 rows and I'm curious if I am missing out on NSFetchedResultsController benefits. Any thoughts on this as well? Can I somehow still benefit from NSFetchedResultsController goodness without having to do a full fetch (as I would have already passed in the data from my previous VC)? Thanks a lot.
