• How to Generate XBRL from Oracle's Applications

  - by Theresa Hickman

  I've been getting quite a few emails asking how Oracle supports XBRL. As of June 2011, all public US companies were required to produce XBRL-based financial statements to the SEC. The latest XBRL 2.1 specifications are supported by Oracle Hyperion Disclosure Management, which supports the XBRL tagging of financial statements as well as the disclosures and footnotes within your 10K and 10Q filings. Because many of our customers use Hyperion Financial Management (HFM) for their consolidation needs, they simply generate XBRL statements from their consolidated financial results. Click here to watch a 3 min demo about this cool tool. Question: What if you don't use Hyperion Financial Management, and you only use E-Business Suite General Ledger or PeopleSoft General Ledger? Answer: No problem, all you need is Hyperion Disclosure Management to generate XBRL from your general ledger. Here are the steps: Upload the XBRL taxonomy from the SEC or XBRL website into Hyperion Disclosure Management. Publish your financial statements out of general ledger to Excel. Perform the XBRL tag mapping from the Excel output to Hyperion Disclosure Management.

• Making a game with responsive resolution

  - by alexandervrs

  I am making a game, however I wish for it to be resolution agnostic. My target resolution i.e. where things look as intended is 1600 x 900. My ideas are: Make the HUD stay fixed to the sides no matter what resolution, use different size for HUD graphics under a certain resolution and another under a certain large one. Use large HD sprites/backgrounds which are a power of 2, so they scale nicely. Use the player's native resolution. Scale the game area (not the HUD) to fit (resulting zooming in some and cropping the game area sides if necessary for widescreen, no stretch), but always fill the screen. Have a min and max resolution limit for small and very large displays where you will just change the resolution(?) or scale up/down to fit. What I am a bit confused though is what math formula I would use to scale the game area correctly based on the resolution no matter the aspect ratio, fully fit in a square screen and with some clip to the sides for widescreen. Pseudocode would help as well. :)

• How to mange big amount users at server side?

  - by Rami

  I built a social android application in which users can see other users around them by gps location. at the beginning thing went well as i had low number of users, But now that I have increasing number of users (about 1500 +100 every day) I revealed a major problem in my design. In my Google App Engine servlet I have static HashMap that holding all the users profiles objects, currenty 1500 and this number will increase as more users register. Why I'm doing it Every user that requesting for the users around him compares his gps with other users and check if they are in his 10km radius, this happens every 5 min on average. That is why I can't get the users from db every time because GAE read/write operation quota will tare me apart. The problem with this desgin is As the number of users increased the Hashmap turns to null every 4-6 hours, I thing that this time is getting shorten but I'm not sure. I'm fixing this by reloading the users from the db every time I detect that it became null, But this causes DOS to my users for 30 sec, So I'm looking for better solution. I'm guessing that it happens because the size of the hashmap, Am I right? I have been advised to use spatial database, but that mean that I can't work with GAE any more and that mean that I need to build my big server all over again and lose my existing DB. Is there something I can do with the existing tools? Thanks.

• How do I get a Belkin F5D8053 wireless adapter working?

  - by disassembler

  I've tried getting my Belkin N Wireless adapter to work on Ubuntu many times with no luck at all. Each time I seem to arrive at a dead end.

• Nordics OTN ACE Tour 2013 - Recap

  - by Mike Dietrich

  The Nordics OTN ACE Tour 2013 with stops in Stockholm, Ballerup/Copenhagen and Oslo is over. A very intense week with plenty of excellent presentations from Lonneke Dikmans, Sten Vesterli, Tim Hall and others. I'm always impressed how much those people know and how good they present. It's such a great learning experience. And there's always some time to talk about weired things apart from the Oracle cosmos. So thanks a lot, folks - it was a pleasure to travel with you. And many many thanks also to the people from ORCAN, DOUG and OUGN. Everything worked out so well. And thanks for the great gifts. the dinners, everything!!! Of course a special thanks to all the people who went to my presentations. Hope you've enjoyed it - and sorry for any overtiming But as Tim said yesterday in the Shuttle Bus back to the airport: "45 min slots don't work out at all" The final slide set about "Different Ways to Upgrade, Migrate and Consolidate into Oracle Database 12c including Oracle Multitenant, New Features and other stuff" can be downloaded via this link. Hope to see you all again soon - and let me know once you have successfully upgraded to Oracle Database 12c or in case you'd like to become one of our Upgrade Reference Customers. Cheers - Mike PS: One thing I couldn't really understand - why is that thing below not labeled simply GRAPE JUICE??? And who's honestly drinking that?

• Multiple monitors showing same screen but different resolutions

  - by Luis Alvarado

  Is it possible to have 2 or more monitors showing the same screen, for example the same desktop but with different resolutions. Like the clone option in Nvidia or the mirror option using the Display settings in Ubuntu but instead of showing the same output with the same resolution, the both show the same output using a resolution that is native for each monitor connected. In my case if I have a netbook that has max resolution of 1360x768 and a TV that has 1280x1024, the would both show the same desktop but each with their own resolution that is compatible for each device. This would help in trying to find a resolution that works on both monitors and in cases like a mini netbook and a huge TV it would solve issues like having max 800x600 in one monitor and min 1024x768 in the other. In the case I tested I was using an HDMI cable but this question also involves VGA and any other connection. I have 3 tests scenarios for this: Scenario 1 - Laptop HP DV6000 (Intel Integrated Video) with 1360x760 connected to a Samsung LED 42 TV that has 1280x900. Scenario 2 - Laptop EEE with 1024x600 (Intel Integrated Video) connected to Sony LCD TV that supports 1280x900. Scenario 3 - Intel Desktop with Nvidia 440 GT with HDMI connected to Soneview 32' TV that supports 1920x1080 and VGA connected to an Epson Video Beam that supports 1280x1024 max. In this 3 scenarios I need to be able to show the same desktop and same views but on different resolutions for each output device. UPDATE: Tested with Xubuntu and the way it handles multiple monitors is precisely what I am asking. The ability to handle the resolution of different monitors showing the same thing.

• Mastering snow and Java development at jDays in Gothenburg

  - by JavaCecilia

  Last weekend, I took the train from Stockholm to Gothenburg to attend and present at the new Java developer conference jDays. It was professionally arranged in the Swedish exhibition hall close to the amusement park Liseberg and we got a great deal out of the top-level presenters and hallway discussions. Understanding and Improving Your Java Process Our main purpose was to spread information on JVM and our monitoring tools for Java processes, so I held a crash course in the most important terms and concepts if you want to affect the performance of your Java process. From the beginning - the JVM specification to interpretation of heap usage graphs. For correct analysis, you also need to understand something about process memory - you need space for the Java heap (-Xms for initial size and -Xmx for max heap size), but the process memory also contain the thread stacks (to a size of -Xss), JVM internal data structures used for keeping track of Java objects on the heap, method compilation/optimization, native libraries, etc. If you get long pause times, make sure to monitor your application, see the allocation rate and frequency of pause times.My colleague Klara Ward then held a presentation on the Java Mission Control product, the profiling and diagnostics tools suite for HotSpot, coming soon. The room was packed and very appreciated, Klara demonstrated four different scenarios, e.g. how to diagnose and fix latencies due to lock contention for logging.My German colleague, OpenJDK ambassador Dalibor Topic travelled to Sweden to do the second keynote on "Make the Future Java". He let us in on the coming features and roadmaps of Java, now delivering major versions on a two-year schedule (Java 7 2011, Java 8 2013, etc). Also letting us in on where to download early versions of 8, to report problems early on. Software Development in teams Being a scout leader, I'm drilled in different team building and workshop techniques, creating strong groups - of course, I had to attend Henrik Berglund's session on building successful teams. He spoke about the importance of clear goals, autonomy and agreed processes. Thomas Sundberg ended the conference by doing live remote pair programming with Alex in Rumania and a concrete tips for people wanting to try it out (for local collaboration, remember to wash and change clothes). Memory Master Keynote The conference keynote was delivered by the Swedish memory master Mattias Ribbing, showing off by remembering the order of a deck of cards he'd seen once. He made it interactive by forcing the audience to learn a memory mastering technique of remembering ten ordered things by heart, asking us to shout out the order backwards and we made it! I desperately need this - bought the book, will get back on the subject. Continuous Delivery The most impressive presenter was Axel Fontaine on Continuous Delivery. Very well prepared slides with key images of his message and moved about the stage like a rock star. The topic is of course highly interesting, how to create an infrastructure enabling immediate feedback to developers and ability to release your product several times per day. Tomek Kaczanowski delivered a funny and useful presentation on good and bad tests, providing comic relief with poorly written tests and the useful rules of thumb how to rewrite them. To conclude, we had a great time and hope to see you at jDays next year :)

• dynamic 2d texture creation in unity from script

  - by gman

  I'm coming from HTML5 and I'm used to having the 2D Canvas API I can use to generate textures. Is there anything similar in Unity3D? For example, let's say at runtime I want to render a circle, put 3 initials in the middle and then take the result and put that in a texture. In HTML5 I'd do this var initials = "GAT"; var textureWidth = 256; var textureHeight = 256; // create a canvas var c = document.createElement("canvas"); c.width = textureWidth; c.height = textureHeight; var ctx = c.getContext("2d"); // Set the origin to the center of the canvas ctx.translate(textureWidth / 2, textureHeight / 2); // Draw a yellow circle ctx.fillStyle = "rgb(255,255,0)"; // yellow ctx.beginPath(); var radius = (Math.min(textureWidth, textureHeight) - 2) / 2; ctx.arc(0, 0, radius, 0, Math.PI * 2, true); ctx.fill(); // Draw some black initials in the middle. ctx.fillStyle = "rgb(0,0,0)"; ctx.font = "60pt Arial"; ctx.textAlign = "center"; ctx.fillText(initials, 0, 30); // now I can make a texture from that var tex = gl.createTexture(); gl.bindTexture(gl.TEXTURE_2D, tex); gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, gl.RGBA, gl.UNSIGNED_BYTE, c); gl.generateMipmap(gl.TEXTURE_2D); I know I can edit individual pixels in a Unity texture but is there any higher level API for drawing to texture in unity?

• Looking into the jQuery LazyLoad Plugin

  - by nikolaosk

  I have been using JQuery for a couple of years now and it has helped me to solve many problems on the client side of web development.  You can find all my posts about JQuery in this link. In this post I will be providing you with a hands-on example on the JQuery LazyLoad Plugin.If you want you can have a look at this post, where I describe the JQuery Cycle Plugin.You can find another post of mine talking about the JQuery Carousel Lite Plugin here. Another post of mine regarding the JQuery Image Zoom Plugin can be found here. You can have a look at the JQuery Overlays Plugin here . There are times when when I am asked to create a very long page with lots of images.My first thought is to enable paging on the proposed page. Imagine that we have 60 images on a page. There are performance concerns when we have so many images on a page. Paging can solve that problem if I am allowed to place only 5 images on a page.Sometimes the customer does not like the idea of the paging.Believe it or not some people find the idea of paging not attractive at all.In that case I need a way to only load the initial set of images and as the user scrolls down the page to load the rest.So as someone scrolls down new requests are made to the server and more images are fetched. I can accomplish that with the jQuery LazyLoad Plugin.This is just a plugin that delays loading of images in long web pages.The images that are outside of the viewport (visible part of web page) won't be loaded before the user scrolls to them. Using jQuery LazyLoad Plugin on long web pages containing many large images makes the page load faster. In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like. You can use Visual Studio 2012 Express edition. You can download it here.  You can download this plugin from this link. I launch Expression Web 4.0 and then I type the following HTML markup (I am using HTML 5)<!DOCTYPE html><html lang="en">  <head>    <title>Liverpool Legends</title>    <script type="text/javascript" src="jquery-1.8.3.min.js"></script>        <script type="text/javascript" src="jquery.lazyload.min.js" ></script></head>  <body>    <header>                <h1>Liverpool Legends</h1>    </header>        <div id="main">             <img src="barnes.JPG" width="800" height="1100" /><p />        <img src="dalglish.JPG" width="800" height="1100" /><p />                <img class="LiverpoolImage" src="loader.gif" data-original="fans.JPG" width="1200" height="900" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="lfc.JPG" width="1000" height="700" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="Liverpool-players.JPG" width="1100" height="900" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="steven_gerrard.JPG" width="1110" height="1000" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="robbie.JPG" width="1200" height="1000" /><p />          </div>            <footer>        <p>All Rights Reserved</p>      </footer>                    <script type="text/javascript">                $(function () {                    $("img.LiverpoolImage").lazyload();                });        </script>     </body>  </html> This is a very simple markup. I have  added references to the JQuery library (current version is 1.8.3) and the JQuery LazyLoad Plugin. Firstly, I add two images         <img src="barnes.JPG" width="800" height="1100" /><p />        <img src="dalglish.JPG" width="800" height="1100" /><p />  that will load immediately as soon as the page loads. Then I add the images that will not load unless they become active in the viewport. I have all my img tags pointing the src attribute towards a placeholder image. I’m using a blank 1×1 px grey image,loader.gif.The five images that will load as the user scrolls down the page follow.         <img class="LiverpoolImage" src="loader.gif" data-original="fans.JPG" width="1200" height="900" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="lfc.JPG" width="1000" height="700" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="Liverpool-players.JPG" width="1100" height="900" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="steven_gerrard.JPG" width="1110" height="1000" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="robbie.JPG" width="1200" height="1000" /><p /> Then we need to rename the image src to point towards the proper image placeholder. The full image URL goes into the data-original attribute.The Javascript code that makes it all happen follows. We need to make a call to the JQuery LazyLoad Plugin. We add the script just before we close the body element.         <script type="text/javascript">                $(function () {                    $("img.LiverpoolImage").lazyload();                });        </script>We can change the code above to incorporate some effects.          <script type="text/javascript">  $("img.LiverpoolImage").lazyload({    effect: "fadeIn"  });    </script> That is all I need to write to achieve lazy loading. It it true that you can do so much with less!!I view my simple page in Internet Explorer 10 and it works as expected. I have tested this simple solution in all major browsers and it works fine. You can test it yourself and see the results in your favorite browser. Hope it helps!!!

• Running CORN job on Ubuntu server for SugarCRM

  - by Logik

  i am pretty inexperienced in Linux.So be descriptive on your answer. My environment :Local Linux server 12.04 hosting Sugar CRM 6.5.2. There is area in sugar CRM called scheduler. I can configured some predefined jobs here. in my case i am trying to run email reminders (ever min/hour/day/month). For this scheduler to be effective, i read some where i need to setup CRON job. So i did some research & finally put following lines in CRONTAB for the root user, as per instructions given in sugarCRM. cd /var/www/crm; php -f cron.php /dev/null 2&1 Well i am creating contracts in my sugarCRM (AOS module) & i want email reminders to be sent for these contracts to the concern person. Now my sugarCRM email is configured correctly & i can send test emails using it. But the CRON + scheduler not giving any result. I can't receive any emails. Then i tried to read /var/log/syslog & it is showing entry for following line each minute. Oct 27 15:03:01 unicomm CRON[28182]: (root) CMD (cd /var/www/crm; php -f cron.php /dev/null 2&1) I've few questions: 1) what does the CRON job line i've added in crontab mean? cd /var/www/crm; php -f cron.php /dev/null 2&1 is not making any sense to me. 2) How am i suppose to get this thing work? I've searched a lot (including SugarCRM forum), but no luck.

• Netbook Remix 10.04 to 10.10 upgrade using alternate iso

  - by Suman Subramonian

  I'm using Netbook Remix 10.04 now. I'm having the 10.10 alternate iso with me. If I use that iso to upgrade, will I lose my netbook version? I've seen in some forums that the upgrade resulted in a change from netbook version to desktop version. Updated on 15/12/2010 I upgraded the OS from 10.04 to 10.10. But I'm getting an error like this after restart: modprobe: FATAL: Could not load /lib/modules/2.6.35-22-generic/modules.dep: No such file or directory I searched in the forums and got a solution like this: Open Terminal gksudo gedit /etc/initramfs-tools/initramfs.conf change the line MODULES=most to MODULES=dep Then use Synaptic (SystemAdministrationSynaptic Package Manager) to reinstall initramfs-tools. I'll be definitely trying this later. After that when the system tries to login, my screen starts flashing with just the ubuntu netbook desktop wallpaper on the screen. No other options will be available. It will be flashing continuosly. If I press the power button then one window comes up with options like Shut down, Restart, Hibernate etc. And the screen won't stop flashing either. I've uploaded a 1 min video. Please go through it as it will give you a clear idea of the error which I'm facing now Video Link Here

• GLSL Normals not transforming propertly

  - by instancedName

  I've been stuck on this problem for two days. I've read many articles about transforming normals, but I'm just totaly stuck. I understand choping off W component for "turning off" translation, and doing inverse/traspose transformation for non-uniform scaling problem, but my bug seems to be from a different source. So, I've imported a simple ball into OpenGL. Only transformation that I'm applying is rotation over time. But when my ball rotates, the illuminated part of the ball moves around just as it would if direction light direction was changing. I just can't figure out what is the problem. Can anyone help me with this? Here's the GLSL code: Vertex Shader: #version 440 core uniform mat4 World, View, Projection; layout(location = 0) in vec3 VertexPosition; layout(location = 1) in vec3 VertexColor; layout(location = 2) in vec3 VertexNormal; out vec4 Color; out vec3 Normal; void main() { Color = vec4(VertexColor, 1.0); vec4 n = World * vec4(VertexNormal, 0.0f); Normal = n.xyz; gl_Position = Projection * View * World * vec4(VertexPosition, 1.0); } Fragment Shader: #version 440 core uniform vec3 LightDirection = vec3(0.0, 0.0, -1.0); uniform vec3 LightColor = vec3(1f); in vec4 Color; in vec3 Normal; out vec4 FragColor; void main() { diffuse = max(0.0, dot(normalize(-LightDirection), normalize(Normal))); vec4 scatteredLight = vec4(LightColor * diffuse, 1.0f); FragColor = min(Color * scatteredLight, vec4(1.0)); }

• Internet slow on one router only [the problem only in Ubuntu] [on hold]

  - by mrSuperEvening

  Internet works perfectly on every other router, but browsing sucks at home (slow browsing and slow loading times). I changed DNS servers to 8.8.0.0, still doesn't help. And funnily, download speed is extremely high on this network (meaning torrents for example), but using browsers and loading websites is extremely slow (only on this network). Do I need to change something in router settings or what can I try? By the way, I use wired connection to router. EDIT: There's no problems when using Windows.

• Making it GREAT! Oracle Partners Building Apps Workshop with UX and ADF in UK

  - by ultan o'broin

  Yes, making is what it's all about. This time, Oracle Partners in the UK were making great looking usable apps with the Oracle Applications Development Framework (ADF) and user experience (UX) toolkit. And what an energy-packed and productive event at the Oracle UK, Thames Valley Park, location it was. Partners learned the fundamentals of enterprise applications UX, why it's important, all about visual design, how to wireframe designs, and then how to build their already-proven designs in ADF. There was a whole day on mobile apps, learning about mobile design principles, free mobile UX and ADF resources from Oracle, and then trying it out. The workshop wrapped up with the latest Release 7 simplified UIs, Mobilytics, and other innovations from Oracle, and a live demo of a very neat ADF Mobile Android app built by an Oracle contractor. And, what a fun two days both Grant Ronald of ADF and myself had in running the workshop with such a great audience, too! I particularly enjoyed the wireframing and visual design sessions interaction; and seeing some outstanding work done by partners. Of note from the UK workshop were innovative design features not seen before and made me all the happier that developers were bringing their own ideas from the consumer IT world of mobility, simplicity, and social to the world of work apps in a smart way within an enterprise methodology too.  Partner wireframe exercise. Applying mobile design principles and UX design patterns means you've already productively making great usable apps! Next, over to Oracle ADF Mobile with it! One simple example from the design of a mobile field service app was that participants immediately saw how the UX and device functionality of the super UK-based app Hailo app could influence their designs (the London cabbie influence maybe?), as well as how we all use maps, cameras, barcode scanners and microphones on our phones could be used in work. And, of course, ADF Mobile has the device integration solutions there too! I wonder will U.S. workshops in Silicon Valley see an Uber UX influence (LOL)! That we also had partners experienced with Oracle Forms who could now offer a roadmap from Forms to Simplified UI and Mobile using ADF, and do it through through the cloud, really made this particular workshop go "ZING!" for me. Many thanks to the Oracle PartnerNetwork (OPN) team for organizing this event with us, and to the representatives of the Oracle Partners that showed and participated so well. That's what I love out this outreach. It's a two-way, solid value-add for all. Interested? Why would partners and developers with ADF skills sign up for this workshop? Here's why: Learn to use the Oracle Applications User Experience design patterns as the usability building blocks for applications development in Oracle Application Development Framework. The workshop enables attendees to build modern and visually compelling desktop and mobile applications that look and behave like Oracle Cloud Applications, and that can co-exist with partner integrations, new, or existing applications deployments. Partners learn to offer customers and clients more than just coded functionality; instead they can provide a complete user experience with a roadmap for continued ROI from applications that also creating more business and attracts the kudos and respect from other makers of apps as they're wowed by the results. So, if you're a partner and interested in attending one of these workshops and benefitting from such learning, as well as having a platform to show off some of your own work, stay well tuned to your OPN channels, to this blog, to the VoX blog, and to the @usableapps Twitter account too. Can't wait?

• Code Clone Analysis on Rawr &ndash; Part 1

  - by Dylan Smith

  In this post we’ll take a look at the first result from the Code Clone Analysis, and do some refactoring to eliminate the duplication.  The first result indicated that it found an exact match repeated 14 times across the solution, with 18 lines of duplicated code in each of the 14 blocks.   Net Lines Of Code Deleted: 179     In this case the code in question was a bunch of classes representing the various Bosses.  Every Boss class has a constructor that initializes a whole bunch of properties of that boss, however, for most bosses a lot of these are simply set to 0’s.     Every Boss class inherits from the class MultiDiffBoss, so I simply moved all the initialization of the various properties to the base class constructor, and left it up to the Boss subclasses to only set those that are different than the default values. In this case there are actually 22 Boss subclasses, however, due to some inconsistencies in the code structure Code Clone only identified 14 of them as identical blocks.  Since I was in there refactoring the 14 identified already, it was pretty straightforward to identify the other 8 subclasses that had the same duplicated behavior and refactor those also.   Note: Code Clone Analysis is pretty slow right now.  It takes approx 1 min to build this solution, but it takes 9 mins to run Code Clone Analysis.  Personally, if the results are high quality I’m OK with it taking a long time to run since I don’t expect it’s something I would be running all that often.  However, it would be nice to be able to run it as part of a nightly build, but at this time I don’t believe it’s possible to run outside of Visual Studio due to a dependency on the meta-data available in the VS environment.

• Code execution time out occationally

  - by Athul k Surendran

  I am working on an e-commerce website. There is a case where I need to fetch the whole data in database through third-party API and send it to an indexing engine. This third-party API has many functions like getproducts, getproductprice, etc., and each of that functions will return the data in XML format. From there I will take charge, I will use various API calls and will handle the XML data with XSLT. And will write to a CSV file. This file will be uploaded to an Indexing engine. Right now I have details of 8000 products to feed the engine, and almost all time the this process takes about 15 min to complete, and sometimes fails. I can't find a better solution for this. I am thinking about handling the XML data in C# itself and get rid of XSLT. As I think, XSLT is far slower than C#. Is it a good Idea? Or what else I can do to solve this issue?

• Flow Fields in Dynamics NAV

  - by T

  I don’t know the exact business reason but someone asked how to identify all sales shipping orders with any negative quantities on them.  They needed to print these separately from the shipments that only have all positive quantities. Here is one way to solve this problem In NAV, open Sales Shipment Header Add a field of type Boolean (The field type should match the value you expect to return from the flow field method.  In this case we will use an exist so we expect a bool but we could have used a Sum, Average, Min, Max, Count, or a Lookup to return a value). Define it as a flow field and click on the ellipse next to CalcFormula Now [Has Negative Qty] is false if no negatives exist And [Has Negative Qty] and true if a negative exist So it is ready to be used as a filter on the report. Don’t forget that if you are using it in code, you may need to CalcFields. Hope that helps.  If you really can’t afford the field in your header, you can use code to check the lines for a negative value each time and use a skip or break function to skip that header record but it seems expensive to check them all if you only want a few to print. Please let me know if you think of a better solution.

• Copy to USB memory stick really slow?

  - by Eloff

  When I copy files to the USB device, it takes much longer than in windows (same usb device, same port) it's faster than USB 1.0 speeds (1MB/s) but much slower than USB 2.0 speeds (12MB/s). To copy 1.8GB takes me over 10 minutes (it should be < 3 min.) I have two identical SanDisk Cruzer 8GB sticks, and I have the same problem with both. I have a super talent 32GB USB SSD in the neighboring port and it works at expected speeds. The problem I seem to see in the GUI is that the progress bar goes to 90% almost instantly, completes to 100% a little slower and then hangs there for 10 minutes. Interrupting the copy at this point seems to result in corruption at the tail end of the file. If I wait for it to complete the copy is successful. Any ideas? dmesg output below: [64059.432309] usb 2-1.2: new high-speed USB device number 5 using ehci_hcd [64059.526419] scsi8 : usb-storage 2-1.2:1.0 [64060.529071] scsi 8:0:0:0: Direct-Access SanDisk Cruzer 1.14 PQ: 0 ANSI: 2 [64060.530834] sd 8:0:0:0: Attached scsi generic sg4 type 0 [64060.531925] sd 8:0:0:0: [sdd] 15633408 512-byte logical blocks: (8.00 GB/7.45 GiB) [64060.533419] sd 8:0:0:0: [sdd] Write Protect is off [64060.533428] sd 8:0:0:0: [sdd] Mode Sense: 03 00 00 00 [64060.534319] sd 8:0:0:0: [sdd] No Caching mode page present [64060.534327] sd 8:0:0:0: [sdd] Assuming drive cache: write through [64060.537988] sd 8:0:0:0: [sdd] No Caching mode page present [64060.537995] sd 8:0:0:0: [sdd] Assuming drive cache: write through [64060.541290] sdd: sdd1 [64060.544617] sd 8:0:0:0: [sdd] No Caching mode page present [64060.544619] sd 8:0:0:0: [sdd] Assuming drive cache: write through [64060.544621] sd 8:0:0:0: [sdd] Attached SCSI removable disk

• D&rsquo;Arcy&rsquo;s Book Club - The New Strategic Selling

  - by D'Arcy Lussier

  The New Strategic Selling Miller and Heiman Amazon.ca Amazon.com Chapters Everybody is a salesmen. Every day, without knowing it, we sell something to someone. Now, the typical vision people think of when they hear the word “sales” is the sleazy used car salesperson who does whatever they can to get you to buy the clunker on their lot. But selling is not an action tied to money and products. Selling is about convincing people to see your point of view and act on it. If you want your company to cover a trip to a conference, you may have to sell the idea to your boss. If you want to buy that new big screen TV, you have to sell the idea to your significant other. If you want to go on a weekend fishing trip with the boys you might be called in to help sell the idea to your buddies wife. We all sell, but we don’t all sell very well. So enter The New Strategic Selling, a book based on the sales course put on by the Miller-Heiman group. In fact, this isn’t really a “New” strategy to selling as its been around for a number of years. But the concepts they present, the ideas about selling, these are still very radical based on what most of us have experienced. Gone are the high pressure, win at all cost, GlenGarry-GlenRoss style of sales…instead the book presents a framework to switch to need-based selling. It’s the idea that instead of going in raving about a product or service, you build a relationship where the buyer expresses what their needs are and your response is to present a solution that best fits that need. Instead of focussing on the amount of money you can squeeze out of a client, you focus on whether everyone wins, that they receive win-results from the engagement, that repeat business is developed over time delivering value over and over again. The great thing about the book is that what it teaches…things like how to identify different buying influencers, how to prepare for meetings, techniques to solicit information about what the buyer is really thinking/feeling…these things are entirely applicable in *any* situation that you need to sell to someone…and remember: selling is convincing people to see your point of view and act on it. So that new big screen TV you want to buy but need to convince your wife on? This book can help you. That training opportunity you want your company to send you on? This book can help you. The upgrade to your community park that you want to lobby the local civic authorities for? This book can help you. The book is a bit wordy. I found that the length could have been reduced and the points still have gotten across. That’s really the only knock that I have though; the insight that it provides is so worthwhile that having to chew through extra words is well worth it. You definitely don’t have to be a professional salesperson to benefit from this book. Rating: 4/5

• One-way platform collision

  - by TheBroodian

  I hate asking questions that are specific to my own code like this, but I've run into a pesky roadblock and could use some help getting around it. I'm coding floating platforms into my game that will allow a player to jump onto them from underneath, but then will not allow players to fall through them once they are on top, which require some custom collision detection code. The code I have written so far isn't working, the character passes through it on the way up, and on the way down, stops for a moment on the platform, and then falls right through it. Here is the code to handle collisions with floating platforms: protected void HandleFloatingPlatforms(Vector2 moveAmount) { //if character is traveling downward. if (moveAmount.Y > 0) { Rectangle afterMoveRect = collisionRectangle; afterMoveRect.Offset((int)moveAmount.X, (int)moveAmount.Y); foreach (World_Objects.GameObject platform in gameplayScreen.Entities) { if (platform is World_Objects.Inanimate_Objects.FloatingPlatform) { //wideProximityArea is just a rectangle surrounding the collision //box of an entity to check for nearby entities. if (wideProximityArea.Intersects(platform.CollisionRectangle) || wideProximityArea.Contains(platform.CollisionRectangle)) { if (afterMoveRect.Intersects(platform.CollisionRectangle)) { //This, in my mind would denote that after the character is moved, its feet have fallen below the top of the platform, but before he had moved its feet were above it... if (collisionRectangle.Bottom <= platform.CollisionRectangle.Top) { if (afterMoveRect.Bottom > platform.CollisionRectangle.Top) { //And then after detecting that he has fallen through the platform, reposition him on top of it... worldLocation.Y = platform.CollisionRectangle.Y - frameHeight; hasCollidedVertically = true; } } } } } } } } In case you are curious, the parameter moveAmount is found through this code: elapsed = (float)gameTime.ElapsedGameTime.TotalSeconds; float totalX = 0; float totalY = 0; foreach (Vector2 vector in velocities) { totalX += vector.X; totalY += vector.Y; } velocities.Clear(); velocity.X = totalX; velocity.Y = totalY; velocity.Y = Math.Min(velocity.Y, 1000); Vector2 moveAmount = velocity * elapsed;

• What are some best practices for minimizing code?

  - by CrystalBlue

  While maintaining the sites our development team has created, we have come across include files and plugins that have proven to be very useful to more then one part of our applications. Most of these modules have come with two different files, a normal source file and a min file. Seeing that the performance and speed of a page can be increased by minimizing the size of the file, we're looking into doing that to our pages as well. The problem that we run into is a lot of our normal pages (written in ASP classic) is a mix of HTML, ASP, Javascript, CSS, and include files. We have some pages that have their JS both in include files and in the page, depending on if the function is only really used in that page or if it's used in many other pages. For example, we have a common.js and an ajax.js file, both are used in a lot of pages, but not all of them. As well as having some functions in a page that doesn't really make sense to put into one master page. What I have seen a few other people do online is use one master JS file and place all of their javascript into that, minify it, gzip it, and only use that on their production server. Again, this would be great, but I don't know if that fully works for our purposes. What I'm looking for is some direction to go with on this. I'm in favor of taking all of our JS and putting it in one include file, and just having it included in every page that is hit. However, not every page we have needs every bit of JS. So would it be worth the compilation and minifying of the files into one master file and include it everywhere, or would it be better to minify all other files and still include them on a need-to-use basis?

• Unable to log in due to freeze, occasional error message

  - by Xianlin Xiong

  I'm new to Ubuntu. And I have some problems now. I downloaded Ubuntu 11.10 and burned it onto a CD. Then I load it in my conputer, it's easy. But when I finished those and restarted the computer, the problem comes: After I choose to log in the Ubuntu system,the screen stays in pink, and it can't jump into (about 30 min), and then I have no choices but to press Ctrl+Alt+Del to reboot. Another time I choose Ubuntu to log in, it shows on the screen that "BusyBox v1.18.4 ...... built-in shell ...... initramfs". However the Live CD works very well. What’s more, there is a Windows 7 partition on the hard drive. (Windows 7 is also okay.) But I leave more than 20GB on the hard drive to Ubuntu. When I installed Ubuntu, I only made two partitions (swap and /). I don’t know where the problems happened and how to deal with them. And I hope someone can help me out with the troubles.

• Dirt compression from vehicle tires

  - by Mungoid

  So I kinda have this working but its not correct because it just averages, so I wanted to know if anyone here has any ideas. I'm trying to simulate loose dirt compression under the tires of a vehicle to reduce the potential bumpiness of 'chunky' terrain. Currently how I do this is that I have a bounding box shape around my tires, set a little lower so they intersect with the terrain. Each frame, I (currently) average all of the heights of each point in the terrain that are within the box bounds of that tire, and then set them all to that average. Clearly this won't work in most cases because, for example, if i'm on a hill, the terrain will deform way too much. One way I thought was to have a max and min amount the points could raise and lower but that still doesn't seem to work properly and sometimes looks more like steps than smooth dirt. I wanna say that there is probably a bit more to this that what i'm currently doing but I am not sure where to look. Could anyone here shed some light on this subject? Would I benefit any by maybe looking up some smoothing algorith or something similar?

• How do I turn off PCI devices?

  - by ethana2

  With the purchase of an Intel SSD and 85WHr Li-ion battery and the linking of wifi and bluetooth to my laptop's wireless switch, extensive Intel PowerTop usage, switching from compiz to metacity, stopping of the desktop-couch daemon, removal of Ubuntu One and several other services from my startup, disabling of everything possible in my BIOS, and physical removal of my optical drive, I've gotten my battery life up fairly high, but I think there's still more to be done. Specifically, when I'm in class taking notes, I want to temporarily but completely power down: Ethernet Firewire USB ports SD card reader Optical drive Webcam Sound card PCMCIA slot ..without turning them off in my BIOS like they are now, if possible, because then I have to restart my computer to use any of them. As it stands, I still haven't managed to power down: Firewire USB connection to webcam sound card How do I tell Linux to disable and power down these devices? Is it true that any PCI slot can be physically powered down? My current idle power consumption is 7.9 watts plus the screen. (10.0W at min. brightness) Also, how do I set the screen timeout to ten seconds? gconf editor isn't honoring it when I set it to that. Will switching from nVidia to Nouveau save any significant amount of power?
