  • HLSL/XNA Ambient light texture mixed up with multi pass lighting

    - by Manu-EPITA
    I've been having some troubles lately with lighting. I have found a source on google which is working pretty good on the example. However, when I try to implement it to my current project, I am getting some very weird bugs. The main one is that my textures are "mixed up" when I only activate the ambient light, which means that a model gets the texture of another one . I am using the same effect for every meshes of my models. I guess this could be the problem, but I don't really know how to "reset" an effect for a new model. Is it possible? Here is my shader: float4x4 WVP; float4x4 WVP; float3x3 World; float3 Ke; float3 Ka; float3 Kd; float3 Ks; float specularPower; float3 globalAmbient; float3 lightColor; float3 eyePosition; float3 lightDirection; float3 lightPosition; float spotPower; texture2D Texture; sampler2D texSampler = sampler_state { Texture = <Texture>; MinFilter = anisotropic; MagFilter = anisotropic; MipFilter = linear; MaxAnisotropy = 16; }; struct VertexShaderInput { float4 Position : POSITION0; float2 Texture : TEXCOORD0; float3 Normal : NORMAL0; }; struct VertexShaderOutput { float4 Position : POSITION0; float2 Texture : TEXCOORD0; float3 PositionO: TEXCOORD1; float3 Normal : NORMAL0; }; VertexShaderOutput VertexShaderFunction(VertexShaderInput input) { VertexShaderOutput output; output.Position = mul(input.Position, WVP); output.Normal = input.Normal; output.PositionO = input.Position.xyz; output.Texture = input.Texture; return output; } float4 PSAmbient(VertexShaderOutput input) : COLOR0 { return float4(Ka*globalAmbient + Ke,1) * tex2D(texSampler,input.Texture); } float4 PSDirectionalLight(VertexShaderOutput input) : COLOR0 { //Difuze float3 L = normalize(-lightDirection); float diffuseLight = max(dot(input.Normal,L), 0); float3 diffuse = Kd*lightColor*diffuseLight; //Specular float3 V = normalize(eyePosition - input.PositionO); float3 H = normalize(L + V); float specularLight = pow(max(dot(input.Normal,H),0),specularPower); if(diffuseLight<=0) specularLight=0; float3 specular = Ks * lightColor * specularLight; //sum all light components float3 light = diffuse + specular; return float4(light,1) * tex2D(texSampler,input.Texture); } technique MultiPassLight { pass Ambient { VertexShader = compile vs_3_0 VertexShaderFunction(); PixelShader = compile ps_3_0 PSAmbient(); } pass Directional { PixelShader = compile ps_3_0 PSDirectionalLight(); } } And here is how I actually apply my effects: public void ApplyLights(ModelMesh mesh, Matrix world, Texture2D modelTexture, Camera camera, Effect effect, GraphicsDevice graphicsDevice) { graphicsDevice.BlendState = BlendState.Opaque; effect.CurrentTechnique.Passes["Ambient"].Apply(); foreach (ModelMeshPart part in mesh.MeshParts) { graphicsDevice.SetVertexBuffer(part.VertexBuffer); graphicsDevice.Indices = part.IndexBuffer; // Texturing graphicsDevice.BlendState = BlendState.AlphaBlend; if (modelTexture != null) { effect.Parameters["Texture"].SetValue( modelTexture ); } graphicsDevice.DrawIndexedPrimitives( PrimitiveType.TriangleList, part.VertexOffset, 0, part.NumVertices, part.StartIndex, part.PrimitiveCount ); // Applying our shader to all the mesh parts effect.Parameters["WVP"].SetValue( world * camera.View * camera.Projection ); effect.Parameters["World"].SetValue(world); effect.Parameters["eyePosition"].SetValue( camera.Position ); graphicsDevice.BlendState = BlendState.Additive; // Drawing lights foreach (DirectionalLight light in DirectionalLights) { effect.Parameters["lightColor"].SetValue(light.Color.ToVector3()); effect.Parameters["lightDirection"].SetValue(light.Direction); // Applying changes and drawing them effect.CurrentTechnique.Passes["Directional"].Apply(); graphicsDevice.DrawIndexedPrimitives( PrimitiveType.TriangleList, part.VertexOffset, 0, part.NumVertices, part.StartIndex, part.PrimitiveCount ); } } I am also applying this when loading the effect: effect.Parameters["lightColor"].SetValue(Color.White.ToVector3()); effect.Parameters["globalAmbient"].SetValue(Color.White.ToVector3()); effect.Parameters["Ke"].SetValue(0.0f); effect.Parameters["Ka"].SetValue(0.01f); effect.Parameters["Kd"].SetValue(1.0f); effect.Parameters["Ks"].SetValue(0.3f); effect.Parameters["specularPower"].SetValue(100); Thank you very much UPDATE: I tried to load an effect for each model when drawing, but it doesn't seem to have changed anything. I suppose it is because XNA detects that the effect has already been loaded before and doesn't want to load a new one. Any idea why?

  • MVC DropDownListFor not populating the selected value

    - by user2254436
    I'm really having troubles with MVC, in another project I've done the same thing and it worked fine but in this project I just don't understand why the selected item in the dropdown is not populating the class correctly with EF. I have 2 classes: public partial class License { public License() { this.Customers = new HashSet<Customer>(); } public int LicenseID { get; set; } public int Lic_LicenseTypeID { get; set; } public int Lic_LicenseStatusID { get; set; } public string Lic_LicenseComments { get; set; } public virtual EntitiesList LicenseStatus { get; set; } public virtual EntitiesList LicenseType { get; set; } } public partial class EntitiesList { public EntitiesList() { this.LicensesStatus = new HashSet<License>(); this.LicensesType = new HashSet<License>(); } public int ListID { get; set; } public string List_EntityValue { get; set; } public string List_Comments { get; set; } public string List_EntityName { get; set; } public virtual ICollection<License> LicensesStatus { get; set; } public virtual ICollection<License> LicensesType { get; set; } public string List_DisplayName { get { return Regex.Replace(List_EntityName, "([a-z])([A-Z])", "$1 $2"); ; } } public string List_DisplayValue { get { return Regex.Replace(List_EntityValue, "([a-z])([A-Z])", "$1 $2"); } } } The EntitiesList is table in db that have all my "enum" lists. For example: ListID - 0 List_EntityValue - Activate List_EntityName - LicenseStatus ListID - 1 List_EntityValue - Basic List_EntityName - LicenseType This is my model: public class LicenseModel { public License License { get; set; } public SelectList LicenseStatuses { get; set; } public int SelectedStatus { get; set; } public SelectList LicenseTypes { get; set; } public int SelectedType { get; set; } } My controller for create: public ActionResult Create() { LicenseModel model = new LicenseModel(); model.License = new License(); model.LicenseStatuses = new SelectList(managerLists.GetAllLicenseStatuses(), "ListID", "List_DisplayValue"); model.LicenseTypes = new SelectList(managerLists.GetAllLicenseTypes(), "ListID", "List_DisplayValue"); return View(model); } [HttpPost] [ValidateAntiForgeryToken] public ActionResult Create(LicenseModel model) { if (ModelState.IsValid) { model.License.Lic_LicenseTypeID = model.SelectedType; model.License.Lic_LicenseStatusID = model.SelectedStatus; managerLicense.AddNewObject(model.License); return RedirectToAction("Index"); } return View(model); } managerLists and managerLicense are the managers that connect between the entities in db and the MVC UI, nothing special... they contains queries for adding new objects, getting the lists, editing and so on. And the view for creating the License: @using (Html.BeginForm()) { @Html.AntiForgeryToken() @Html.ValidationSummary(true) <fieldset> <legend>License</legend> <div class="form-group"> @Html.LabelFor(model => model.License.Lic_LicenseTypeID) @Html.DropDownListFor(model => model.SelectedType, Model.LicenseTypes, new { @class = "form-control" }) <p class="help-block">@Html.ValidationMessageFor(model => model.License.Lic_LicenseTypeID)</p> </div> <div class="form-group"> @Html.LabelFor(model => model.License.Lic_LicenseStatusID) @Html.DropDownListFor(model => model.SelectedStatus, Model.LicenseStatuses, new { @class = "form-control" }) <p class="help-block">@Html.ValidationMessageFor(model => model.License.Lic_LicenseStatusID)</p> </div> <div class="form-group"> @Html.LabelFor(model => model.License.Lic_LicenseComments) @Html.TextAreaFor(model => model.License.Lic_LicenseComments, new { @class = "form-control", rows = "3" }) <p class="help-block">@Html.ValidationMessageFor(model => model.License.Lic_LicenseComments)</p> </div> <p> <input type="submit" value="Create" /> </p> </fieldset> } Now, when I'm trying to save the new license, when it gets to the db.SaveChanges() in the manager I'm getting: "Validation failed for one or more entities. See 'EntityValidationErrors' property for more details." In breakpoint, the Lic_LicenseTypeID and Lic_LicenseStatusID are getting correctly the ID's from the selected item in the dropdown but the LicenseStatus and LicenseStatus properties are null. What an I missing?

  • Problems configuring nameserver in plesk

    - by Saif Bechan
    Hello, i have some troubles with setting up a nameserver in PLESK for months now. I have tried all possible scenario's but i can not get this to work. I am really in need for some help, and if you can i will really appreciate it. Basically what i want is to just set up a nameserver in PLESK. I have a primary IP, and my host gave me a secondary nameserver i can use. My host is leaseweb in the netherlands. I have made some screenshots of the important parts in my opinion, maybe you guys can see some errors in them. To use the secondary nameserver provided by leaseweb i had to enable ACL on that account, i did so and made a screenshot of that too. The DNS recursion is set to localnets. These settings have not changed for months, so the dns should be fully updated everywhere. The check i run is the following: https://www.sidn.nl/over-nl/aanvraag...-server-check/ Domeinnaam (inclusief .nl): rdshosting.nl Eerste Nameserver: ns1.rdshosting.nl Eerste IP: 62.212.66.33 Tweede Nameserver: ns7.leaseweb.net Tweede ip: 62.212.76.50 If i run the dns check of the netherlands it gives me the following errors: primary name server "ns1.rdshosting.nl." Error: specified name server is not listed as NS record. All public name servers for a domain must also be listed as NS records in the zone of the domain. This domain was specified explicitly as a name server, but not found in the zone description of the primary name server. TE.6a rdshosting.nl. 86400 IN SOA ns1.rdspartners.nl. saif2k.hotmail.com. (2010031102 12H 1H 7D 3H) Error: the MNAME in SOA says "ns1.rdspartners.nl." is the primary name server.

Warning: hidden name server "ns1.rdspartners.nl." never used for first contact. The zone contains an NS record for a host which is not in the list of specified name servers. Hence, this name server will not be used to initiate contact to the domain. It may be used in sequential lookups, so it may still be useful. secondary name server "ns1.rdspartners.nl." [BROKEN] [HIDDEN] Failure: name server at 77.232.85.129 cannot be reached: (unknown error) The name server could not be contacted, which may be due to temporary technical problems or global DNS configuration mistakes.

FreeBSD runs bind in a sandbox (see named_flags in rc.conf). // The directory containing the secondary zones must be write accessible // to bind.

Thank you for your time! PS. I am dutch so dutch answers are welcome aswell

  • My computer freezes irregularly

    - by Manhim
    My computer started to freeze at irregular times for 3 weeks now. Please note that this question change with each things that i try. (For additional details) What happens My computer freezes, the video stops. (No graphic glitches, it just stops) Sound keeps playing up to some time (Usually 10-30 seconds) then stops playing. Sometimes, randomly, the screen on my G-15 keyboard flickers and I see caracters not at the right places. Usually happens for about 1-2 seconds and a bit before my computer freezes. I have to keep the power button pressed for 4 seconds to shut my computer down. I still hear my hard drives and fans working. Sometimes it works with no problems for a full day, some other times it just keeps freezing each time I restart my computer and I have to leave it for the rest of the day. Sometimes my mouse freezes for a fraction of a second (Like 0.01 to 0.2 seconds) quite randomly, usually before it freezes. No errors spotted by the "Action center" unlike when I had problems with my last video card on this system (Driver errors). My G-15 LCD screen also freezes. Sometimes my G-15 LCD screen flickers and caracters gets caried around temporary under heavy load. Now, most of the times, the BIOS hard disks boot order gets reversed for some reason and I have to put it to the right one and save each times I boot. (Might be unrelated, not sure, but it first started yesterday) Sometimes the BIOS doesn't detect my 750GB hard drive plugged in SATA1. What I did so far I have had similar problems in the past and I had changed my hard drive (It was faulty), so I tested my software RAID-0 array and it was faulty so I changed it. (I reinstalled Windows 7 with this part). I also tested with unplugging my secondary hard drive. My CPU was running at about 100 degree Celsius, I removed the dust between the fans and the heatsink and it's now between 45-55. I ran a CPU stress-test and it didn't freeze during the tests (using Prime95 on all cores) Ran a memory test (using memtest86+) for a single pass and there were no errors. Ran a GPU stress test with ati-tools and furmark and it didn't freeze during the tests. (No artefacts either) I had troubles with my graphic card when I got it, but I think that it got fixed with a driver update. I checked the voltages in my BIOS setup and they all seemed ok (±0.2 I think). I have ran on the computer without problems with Fedora 15 on an external hard drive (Appart that it couldn't load Gnome 3 and was reverting to Gnome 2, didn't want to install drivers since I use it on multiple computers) I used it to backup my files from the raid array to my 1TB hard drive for the reinstallation of Windows. (So the crashes only happenned on Windows) [The external hard drive is plugged directly on a SATA port] I contacted EVGA (My graphic card vendor) and pointed them on this question, I'm looking for an answer. Ran sensors on Fedora 15 and got this output: http://pastebin.com/0BHJnAvu Ran 6 short different CPU stress test on Fedora 15 (Haven't found any complete stress testers for Linux) and it didn't crash. Changed the thermal paste to some Artic Silver 5 for my CPU and stress tested the CPU, temperature was at 50 idle, then 64 highest and slowly went down to 62 during the test. Ran some stress testing with a temporary graphic card and it went ok. Ran furmark stress test with my original graphic card and it freezed again. GPU had a temp of 74C, a CPU temp of 58C and a mobo temp of 40C or 45C (Dunno which one it is from SpeedFan). Ran a furmark stress test and a CPU stress test at the same time, results: http://pastebin.com/2t6PLpdJ I have been using my computer without stressing it for about 2 hours now and no crashes yet. I also have disabled the AMD Cool'n'quiet function on the BIOS for a more regular power to the CPU. When I ran Furmark without C'n'q my computer didn't freeze but I had a "Driver Kernel Error" that have recovered (And Furmark crashed) all that while running a CPU stress test. The computer eventually frozed without me being at it, but this time my screen just went on sleep and I couldn't wake it. Using the stability tester in nTune my computer freezed again (In the same manner as before). I notived that Speedfan gives me a -12V of -16.97V and a -5V of -8.78V. I wonder if these numbers are reliable and if they are good or bad. I have swapped my G-15 with another basic USB keyboard (HP) and I have ran furmark for about 10 minutes with a CPU stability test running each 60 seconds for 30 seconds and my computer haven't crashed yet. Ran some more extended tests without my G-15 and it freezed like it usually do. Removed the nForce Hard disk controler. Disabled command queuing in the NVIDIA nForce SATA Controller for both port 0 and port 1 (Errors from the logs) Used CPUID HwMonitor, here are the voltages: http://pastebin.com/dfM7p4jV Changed some configurations in the motherboard BIOS: Disabled PEG Link Mode, Changed AI Tuning to Standard, Disabled the 1394 Controller, Disabled HD Audio, Disabled JMicron RAID controller and Disabled SATA Raid. When it happens When I play video games (Mostly) When I play flash games (Second most) When I'm looking at my desktop background (It rarely happens when I have a window open, but it does, sometimes) When my Graphic card and my CPU are stressed. Sometimes when my Graphic card is stressed. Never happenned while stressing only the CPU. Sometimes when my CPU is stressed. Specs Windows Seven x64 Home Premium Motherboard: M2N-SLI Deluxe CPU: AMD Phenom 9950 x2 @ 2.6GHz Memory: Kingston 4x2GB Dual Channel (Pretty basic memory sticks) Hard drives: Was 2x250GB (Western digital caviar) in raid-0 + 1TB (WD caviar black), I replaced the raid array with a 750GB (WD caviar black) [Yes I removed the array from the raid configurations] 750W Power supply No overcloking. Ever. There have been some power-downs like 4-5 weeks ago, but the problem didn't start immediately after. (I wasn't home, so my computer got shut-down) Event logs (Warnings, errors and critical errors) for the last 24 hours: http://pastebin.com/Bvvk31T7 My current to-try list Reinstall the drivers and software 1 by 1 and do extensive stress testing between each. Update the BIOS firmware to the most recent stable one. Change my motherboard. Status updates Keeping only the last 3 (28/06 04pm) More stress testing and still pass the tests. (28/06 03pm) Been stress testing for 10 minute straight now and 5 minutes with both CPU and GPU being stressed at the same time. (28/06 03pm) Stress-testing right now, so far no problems. A little hope Tests with Furmark and Prime95. Testing Windows bare-bone: 30 Minutes stress, no freeze. Installing an Anti-virus and some software, restarting computer. Testing with Anti-virus and some software (No drivers installed): 30 Minutes stress, no freeze. Installing audio drivers, restarting computer. Testing with the audio drivers: 30 Minutes stress, no freeze. Installing the latest graphic drivers from EVGA's website (without 3d vision since I don't use it), restarting computer. Testing with the graphic drivers: 30 Minutes stress, no freeze. Configuring Windows to my liking and installing more softwares. In this situation, how can I successfully pin-point the current hardware problem? (If it's a hardware problem) Because I don't really have the budget to just forget and replace everything. I also don't really have hardware to test-replace current hardware.

  • nginx + apache subdomain redirection fault

    i really need your advice folks since i'm experiencing some troubles with nginx & apache2 subdomains configs first of all, there's a site (say, site.com) and two subdomains (links.site.com and shop.site.com) whose files are physically located at the same level of FS hierarchy as the site.com itself my hoster has configured both apache and nginx by my request, but it still doesn't work as it used to both of subdomains point to the main page of site.com for some unknown and implicit (for me) reason :( my assumption is that's happen because site.com record is placed first in both configs?!.. please help me solve this out! every opinion would be appreciated =) nginx.conf: server { listen 95.169.187.234:80; server_name site.com www.site.com ; access_log /home/www/site.com/logs/nginx.access.log main; location ~* ^.+\.(jpeg|jpg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|swf|avi|mp3|mpg|mpeg|asf|vmw)$ { expires 30d; root /home/www/site.com/www; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # location ~ /\.ht { deny all; } location / { set $referer $http_referer; proxy_pass http://127.0.0.1:8080/; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Referer $referer; proxy_set_header Host $host; client_max_body_size 10m; client_body_buffer_size 64k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; } } server { listen 95.169.187.234:80; server_name links.site.com www.links.site.com ; access_log /home/www/links.site.com/logs/nginx.access.log main; location ~* ^.+\.(jpeg|jpg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|swf|avi|mp3|mpg|mpeg|asf|vmw)$ { expires 30d; root /home/www/links.site.com/www; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # location ~ /\.ht { deny all; } location / { set $referer $http_referer; proxy_pass http://127.0.0.1:8080/; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Referer $referer; proxy_set_header Host $host; client_max_body_size 10m; client_body_buffer_size 64k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; } } server { listen 95.169.187.234:80; server_name shop.site.com www.shop.site.com ; access_log /home/www/shop.site.com/logs/nginx.access.log main; location ~* ^.+\.(jpeg|jpg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|swf|avi|mp3|mpg|mpeg|asf|vmw)$ { expires 30d; root /home/www/shop.site.com/www; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # location ~ /\.ht { deny all; } location / { set $referer $http_referer; proxy_pass http://127.0.0.1:8080/; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Referer $referer; proxy_set_header Host $host; client_max_body_size 10m; client_body_buffer_size 64k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; } } httpd.conf: # ServerRoot "/usr/local/apache2" PidFile /var/run/httpd.pid Timeout 300 KeepAlive On MaxKeepAliveRequests 100 KeepAliveTimeout 15 Listen 127.0.0.1:8080 NameVirtualHost 127.0.0.1:8080 ... #Listen *:80 NameVirtualHost *:80 ServerName www.site.com ServerAlias site.com UseCanonicalName Off CustomLog /home/www/site.com/logs/custom_log combined ErrorLog /home/www/site.com/logs/error_log DocumentRoot /home/www/site.com/www AllowOverride All Options +FollowSymLinks Options -MultiViews Options -Indexes Options Includes Order allow,deny Allow from all DirectoryIndex index.html index.htm index.php ServerName www.links.site.com ServerAlias links.site.com UseCanonicalName Off CustomLog /home/www/links.site.com/logs/custom_log combined ErrorLog /home/www/links.site.com/logs/error_log DocumentRoot /home/www/links.site.com/www AllowOverride All Options +FollowSymLinks Options -MultiViews Options -Indexes Options Includes Order allow,deny Allow from all DirectoryIndex index.html index.htm index.php ServerName www.shop.site.com ServerAlias shop.site.com UseCanonicalName Off CustomLog /home/www/shop.site.com/logs/custom_log combined ErrorLog /home/www/shop.site.com/logs/error_log DocumentRoot /home/www/shop.site.com/www AllowOverride All Options +FollowSymLinks Options -MultiViews Options -Indexes Options Includes Order allow,deny Allow from all DirectoryIndex index.html index.htm index.php # if DSO load module first: LoadModule rpaf_module modules/mod_rpaf-2.0.so RPAFenable On RPAFsethostname On RPAFproxy_ips 127.0.0.1 RPAFheader X-Forwarded-For Include conf/virthost/*.conf

  • Using TPL and PLINQ to raise performance of feed aggregator

    - by DigiMortal
    In this posting I will show you how to use Task Parallel Library (TPL) and PLINQ features to boost performance of simple RSS-feed aggregator. I will use here only very basic .NET classes that almost every developer starts from when learning parallel programming. Of course, we will also measure how every optimization affects performance of feed aggregator. Feed aggregator Our feed aggregator works as follows: Load list of blogs Download RSS-feed Parse feed XML Add new posts to database Our feed aggregator is run by task scheduler after every 15 minutes by example. We will start our journey with serial implementation of feed aggregator. Second step is to use task parallelism and parallelize feeds downloading and parsing. And our last step is to use data parallelism to parallelize database operations. We will use Stopwatch class to measure how much time it takes for aggregator to download and insert all posts from all registered blogs. After every run we empty posts table in database. Serial aggregation Before doing parallel stuff let’s take a look at serial implementation of feed aggregator. All tasks happen one after other. internal class FeedClient {     private readonly INewsService _newsService;     private const int FeedItemContentMaxLength = 255;       public FeedClient()     {          ObjectFactory.Initialize(container =>          {              container.PullConfigurationFromAppConfig = true;          });           _newsService = ObjectFactory.GetInstance<INewsService>();     }       public void Execute()     {         var blogs = _newsService.ListPublishedBlogs();           for (var index = 0; index <blogs.Count; index++)         {              ImportFeed(blogs[index]);         }     }       private void ImportFeed(BlogDto blog)     {         if(blog == null)             return;         if (string.IsNullOrEmpty(blog.RssUrl))             return;           var uri = new Uri(blog.RssUrl);         SyndicationContentFormat feedFormat;           feedFormat = SyndicationDiscoveryUtility.SyndicationContentFormatGet(uri);           if (feedFormat == SyndicationContentFormat.Rss)             ImportRssFeed(blog);         if (feedFormat == SyndicationContentFormat.Atom)             ImportAtomFeed(blog);                 }       private void ImportRssFeed(BlogDto blog)     {         var uri = new Uri(blog.RssUrl);         var feed = RssFeed.Create(uri);           foreach (var item in feed.Channel.Items)         {             SaveRssFeedItem(item, blog.Id, blog.CreatedById);         }     }       private void ImportAtomFeed(BlogDto blog)     {         var uri = new Uri(blog.RssUrl);         var feed = AtomFeed.Create(uri);           foreach (var item in feed.Entries)         {             SaveAtomFeedEntry(item, blog.Id, blog.CreatedById);         }     } } Serial implementation of feed aggregator downloads and inserts all posts with 25.46 seconds. Task parallelism Task parallelism means that separate tasks are run in parallel. You can find out more about task parallelism from MSDN page Task Parallelism (Task Parallel Library) and Wikipedia page Task parallelism. Although finding parts of code that can run safely in parallel without synchronization issues is not easy task we are lucky this time. Feeds import and parsing is perfect candidate for parallel tasks. We can safely parallelize feeds import because importing tasks doesn’t share any resources and therefore they don’t also need any synchronization. After getting the list of blogs we iterate through the collection and start new TPL task for each blog feed aggregation. internal class FeedClient {     private readonly INewsService _newsService;     private const int FeedItemContentMaxLength = 255;       public FeedClient()     {          ObjectFactory.Initialize(container =>          {              container.PullConfigurationFromAppConfig = true;          });           _newsService = ObjectFactory.GetInstance<INewsService>();     }       public void Execute()     {         var blogs = _newsService.ListPublishedBlogs();                var tasks = new Task[blogs.Count];           for (var index = 0; index <blogs.Count; index++)         {             tasks[index] = new Task(ImportFeed, blogs[index]);             tasks[index].Start();         }           Task.WaitAll(tasks);     }       private void ImportFeed(object blogObject)     {         if(blogObject == null)             return;         var blog = (BlogDto)blogObject;         if (string.IsNullOrEmpty(blog.RssUrl))             return;           var uri = new Uri(blog.RssUrl);         SyndicationContentFormat feedFormat;           feedFormat = SyndicationDiscoveryUtility.SyndicationContentFormatGet(uri);           if (feedFormat == SyndicationContentFormat.Rss)             ImportRssFeed(blog);         if (feedFormat == SyndicationContentFormat.Atom)             ImportAtomFeed(blog);                }       private void ImportRssFeed(BlogDto blog)     {          var uri = new Uri(blog.RssUrl);          var feed = RssFeed.Create(uri);           foreach (var item in feed.Channel.Items)          {              SaveRssFeedItem(item, blog.Id, blog.CreatedById);          }     }     private void ImportAtomFeed(BlogDto blog)     {         var uri = new Uri(blog.RssUrl);         var feed = AtomFeed.Create(uri);           foreach (var item in feed.Entries)         {             SaveAtomFeedEntry(item, blog.Id, blog.CreatedById);         }     } } You should notice first signs of the power of TPL. We made only minor changes to our code to parallelize blog feeds aggregating. On my machine this modification gives some performance boost – time is now 17.57 seconds. Data parallelism There is one more way how to parallelize activities. Previous section introduced task or operation based parallelism, this section introduces data based parallelism. By MSDN page Data Parallelism (Task Parallel Library) data parallelism refers to scenario in which the same operation is performed concurrently on elements in a source collection or array. In our code we have independent collections we can process in parallel – imported feed entries. As checking for feed entry existence and inserting it if it is missing from database doesn’t affect other entries the imported feed entries collection is ideal candidate for parallelization. internal class FeedClient {     private readonly INewsService _newsService;     private const int FeedItemContentMaxLength = 255;       public FeedClient()     {          ObjectFactory.Initialize(container =>          {              container.PullConfigurationFromAppConfig = true;          });           _newsService = ObjectFactory.GetInstance<INewsService>();     }       public void Execute()     {         var blogs = _newsService.ListPublishedBlogs();                var tasks = new Task[blogs.Count];           for (var index = 0; index <blogs.Count; index++)         {             tasks[index] = new Task(ImportFeed, blogs[index]);             tasks[index].Start();         }           Task.WaitAll(tasks);     }       private void ImportFeed(object blogObject)     {         if(blogObject == null)             return;         var blog = (BlogDto)blogObject;         if (string.IsNullOrEmpty(blog.RssUrl))             return;           var uri = new Uri(blog.RssUrl);         SyndicationContentFormat feedFormat;           feedFormat = SyndicationDiscoveryUtility.SyndicationContentFormatGet(uri);           if (feedFormat == SyndicationContentFormat.Rss)             ImportRssFeed(blog);         if (feedFormat == SyndicationContentFormat.Atom)             ImportAtomFeed(blog);                }       private void ImportRssFeed(BlogDto blog)     {         var uri = new Uri(blog.RssUrl);         var feed = RssFeed.Create(uri);           feed.Channel.Items.AsParallel().ForAll(a =>         {             SaveRssFeedItem(a, blog.Id, blog.CreatedById);         });      }        private void ImportAtomFeed(BlogDto blog)      {         var uri = new Uri(blog.RssUrl);         var feed = AtomFeed.Create(uri);           feed.Entries.AsParallel().ForAll(a =>         {              SaveAtomFeedEntry(a, blog.Id, blog.CreatedById);         });      } } We did small change again and as the result we parallelized checking and saving of feed items. This change was data centric as we applied same operation to all elements in collection. On my machine I got better performance again. Time is now 11.22 seconds. Results Let’s visualize our measurement results (numbers are given in seconds). As we can see then with task parallelism feed aggregation takes about 25% less time than in original case. When adding data parallelism to task parallelism our aggregation takes about 2.3 times less time than in original case. More about TPL and PLINQ Adding parallelism to your application can be very challenging task. You have to carefully find out parts of your code where you can safely go to parallel processing and even then you have to measure the effects of parallel processing to find out if parallel code performs better. If you are not careful then troubles you will face later are worse than ones you have seen before (imagine error that occurs by average only once per 10000 code runs). Parallel programming is something that is hard to ignore. Effective programs are able to use multiple cores of processors. Using TPL you can also set degree of parallelism so your application doesn’t use all computing cores and leaves one or more of them free for host system and other processes. And there are many more things in TPL that make it easier for you to start and go on with parallel programming. In next major version all .NET languages will have built-in support for parallel programming. There will be also new language constructs that support parallel programming. Currently you can download Visual Studio Async to get some idea about what is coming. Conclusion Parallel programming is very challenging but good tools offered by Visual Studio and .NET Framework make it way easier for us. In this posting we started with feed aggregator that imports feed items on serial mode. With two steps we parallelized feed importing and entries inserting gaining 2.3 times raise in performance. Although this number is specific to my test environment it shows clearly that parallel programming may raise the performance of your application significantly.

  • Data Modeling: Logical Modeling Exercise

    - by swisscheese
    In trying to learn the art of data storage I have been trying to take in as much solid information as possible. PerformanceDBA posted some really helpful tutorials/examples in the following posts among others: is my data normalized? and Relational table naming convention. I already asked a subset question of this model here. So to make sure I understood the concepts he presented and I have seen elsewhere I wanted to take things a step or two further and see if I am grasping the concepts. Hence the purpose of this post, which hopefully others can also learn from. Everything I present is conceptual to me and for learning rather than applying it in some production system. It would be cool to get some input from PerformanceDBA also since I used his models to get started, but I appreciate all input given from anyone. As I am new to databases and especially modeling I will be the first to admit that I may not always ask the right questions, explain my thoughts clearly, or use the right verbage due to lack of expertise on the subject. So please keep that in mind and feel free to steer me in the right direction if I head off track. If there is enough interest in this I would like to take this from the logical to physical phases to show the evolution of the process and share it here on Stack. I will keep this thread for the Logical Diagram though and start new one for the additional steps. For my understanding I will be building a MySQL DB in the end to run some tests and see if what I came up with actually works. Here is the list of things that I want to capture in this conceptual model. Edit for V1.2 The purpose of this is to list Bands, their members, and the Events that they will be appearing at, as well as offer music and other merchandise for sale Members will be able to match up with friends Members can write reviews on the Bands, their music, and their events. There can only be one review per member on a given item, although they can edit their reviews and history will be maintained. BandMembers will have the chance to write a single Comment on Reviews about the Band they are associated with. Collectively as a Band only one Comment is allowed per Review. Members can then rate all Reviews and Comments but only once per given instance Members can select their favorite Bands, music, Merchandise, and Events Bands, Songs, and Events will be categorized into the type of Genre that they are and then further subcategorized into a SubGenre if necessary. It is ok for a Band or Event to fall into more then one Genre/SubGenre combination. Event date, time, and location will be posted for a given band and members can show that they will be attending the Event. An Event can be comprised of more than one Band, and multiple Events can take place at a single location on the same day Every party will be tied to at least one address and address history shall be maintained. Each party could also be tied to more then one address at a time (i.e. billing, shipping, physical) There will be stored profiles for Bands, BandMembers, and general members. So there it is, maybe a bit involved but could be a great learning tool for many hopefully as the process evolves and input is given by the community. Any input? EDIT v1.1 In response to PerformanceDBA U.3) That means no merchandise other than Band merchandise in the database. Correct ? That was my original thought but you got me thinking. Maybe the site would want to sell its own merchandise or even other merchandise from the bands. Not sure a mod to make for that. Would it require an entire rework of the Catalog section or just the identifying relationship that exists with the Band? Attempted a mod to sell both complete albums or song. Either way they would both be in electronic format only available for download. That is why I listed an Album as being comprised of Songs rather then 2 separate entities. U.5) I understand what you bring up about the circular relation with Favorite. I would like to get to this “It is either one Entity with some form of differentiation (FavoriteType) which identifies its treatment” but how to is not clear to me. What am I missing here? u.6) “Business Rules This is probably the only area you are weak in.” Thanks for the honest response. I will readdress these but I hope to clear up some confusion in my head first with the responses I have posted back to you. Q.1) Yes I would like to have Accepted, Rejected, and Blocked. I am not sure what you are referring to as to how this would change the logical model? Q.2) A person does not have to be a User. They can exist only as a BandMember. Is that what you are asking? Minor Issue Zero, One, or More…Oops I admit I forgot to give this attention when building the model. I am submitting this version as is and will address in a future version. I need to read up more on Constraint Checking to make sure I am understanding things. M.4) Depends if you envision OrderPurchase in the future. Can you expand as to what you mean here? EDIT V1.2 In response to PerformanceDBA input... Lessons learned. I was mixing the concept of Identifying / Non-Identifying and Cardinality (i.e. Genre / SubGenre), and doing so inconsistently to make things worse. Associative Tables are not required in Logical Diagrams as their many-to-many relationships can be depicted and then expanded in the Physical Model. I was overlooking the Cardinality in a lot of the relationships The importance of reading through relationships using effective Verb Phrases to reassure I am modeling what I want to accomplish. U.2) In the concept of this model it is only required to track a Venue as a location for an Event. No further data needs to be collected. With that being said Events will take place on a given EventDate and will be hosted at a Venue. Venues will host multiple events and possibly multiple events on a given date. In my new model my thinking was that EventDate is already tied to Event . Therefore, Venue will not need a relationship with EventDate. The 5th and 6th bullets you have listed under U.2) leave me questioning my thinking though. Am I missing something here? U.3) Is it time to move the link between Item and Band up to Item and Party instead? With the current design I don't see a possibility to sell merchandise not tied to the band as you have brought up. U.5) I left as per your input rather than making it a discrete Supertype/Subtype Relationship as I don’t see a benefit of having that type of roll up. Additional Revisions AR.1) After going through the exercise for FavoriteItem, I feel that Item to Review requires a many-to-many relationship so that is indicated. Necessary? Ok here we go for v1.3 I took a few days on this version, going back and forth with my design. Once the logical process is complete, as I want to see if I am on the right track, I will go through in depth what I had learned and the troubles I faced as a beginner going through this process. The big point for this version was it took throwing in some Keys to help see what I was missing in the past. Going through the process of doing a matrix proved to be of great help also. Regardless of anything, if it wasn't for the input given by PerformanceDBA I would still be a lost soul wondering in the dark. Who knows my current design might reaffirm that I still am, but I have learned a lot so I am know I at least have a flashlight in my hand. At this point in time I admit that I am still confused about identifying and non-identifying relationships. In my model I had to use non-identifying relationships with non nulls just to join the relationships I wanted to model. In reading a lot on the subject there seems to be a lot of disagreement and indecisiveness on the subject so I did what I thought represented the right things in my model. When to force (identifying) and when to be free (non-identifying)? Anyone have inputs? EDIT V1.4 Ok took the V1.3 inputs and cleaned things up for this V1.4 Currently working on a V1.5 to include attributes.

  • XSLT 1.0 help with recursion logic

    - by DashaLuna
    Hello guys, I'm having troubles with the logic and would apprecite any help/tips. I have <Deposits> elements and <Receipts> elements. However there isn't any identification what receipt was paid toward what deposit. I am trying to update the <Deposits> elements with the following attributes: @DueAmont - the amount that is still due to pay @Status - whether it's paid, outstanding (partly paid) or due @ReceiptDate - the latest receipt's date that was paid towards this deposit Every deposit could be paid with one or more receipts. It also could happen, that 1 receipt could cover one or more deposits. For example. If there are 3 deposits: 500 100 450 That are paid with the following receipts: 200 100 250 I want to get the following info: Deposit 1 is fully paid (status=paid, dueAmount=0, receiptNum=3. Deposit 2 is partly paid (status=outstanding, dueAmount=50, receiptNum=3. Deposit 3 is not paid (status=due, dueAmount=450, receiptNum=NAN. I've added comments in the code explaining what I'm trying to do. I am staring at this code for the 3rd day now non stop - can't see what I'm doing wrong.

  • Ubuntu and Windows 8 shared partition gets corrupted

    - by Bruno-P
    I have a dual boot (Ubuntu 12.04 and Windows 8) system. Both systems have access to an NTFS "DATA" partition which contains all my images, documents, music and some application data like Chrome and Thunderbird Profiles which used by both OS. Everything was working fine in my Dual boot Ubuntu/Windows 7, but after updating to Windows 8 I am having a lot of troubles. First, sometimes, I add some files from Ubuntu into my DATA partition but they don't show up in Windows. Sometimes, I can't even use the DATA partition from Windows. When I try to save a file it gives an error "The directory or file is corrupted or unreadable". I need to run checkdisk to fix it but after some time, same error appears. Before upgrading to Windows 8 I also installed a new hard drive and copied the old data using clonezilla (full disk clone). Here is the log of my last chkdisk: Chkdsk was executed in read/write mode. Checking file system on D: Volume dismounted. All opened handles to this volume are now invalid. Volume label is DATA. CHKDSK is verifying files (stage 1 of 3)...

like PersonalInfo,contactInfo,Address there will be only one record, but for tags like "OtherInfo","academicInfo","ProfessionalInfo" there will be multiple records so in xml there are tags for that. now to edit tags having one record only for one user i did coding like: private void FillFamilyInfoControls(XElement rootElement) { ddlSunsign.DataBind(); XElement parentElement; string xPathQuery = "FamilyInfo/Fields"; parentElement = rootElement.XPathSelectElement(xPathQuery); txtGallantryHistory.Text = parentElement.Element("GallantryHistory").Attribute("value").Value; txtEthinicity.Text = parentElement.Element("Ethinicity").Attribute("value").Value; txtKulDev.Text = parentElement.Element("KulDev").Attribute("value").Value; txtKulDevi.Text = parentElement.Element("KulDevi").Attribute("value").Value; txtCaste.Text = parentElement.Element("Caste").Attribute("value").Value; ddlSunsign.SelectedValue = parentElement.Element("SunSignId").Attribute("value").Value; ddlSunsign.SelectedItem.Text = parentElement.Element("SunSignName").Attribute("value").Value; } private XElement UpdateFamilyInfoXML(XElement rootElement) { XElement parentElement; string xPathQuery = "FamilyInfo/Fields"; parentElement = rootElement.XPathSelectElement(xPathQuery); parentElement.Element("GallantryHistory").Attribute("value").Value = txtGallantryHistory.Text; parentElement.Element("Ethinicity").Attribute("value").Value = txtEthinicity.Text; parentElement.Element("KulDev").Attribute("value").Value = txtKulDev.Text; parentElement.Element("KulDevi").Attribute("value").Value = txtKulDevi.Text; parentElement.Element("Caste").Attribute("value").Value = txtCaste.Text; parentElement.Element("SunSignId").Attribute("value").Value = ddlSunsign.SelectedItem.Value; parentElement.Element("SunSignName").Attribute("value").Value = ddlSunsign.SelectedItem.Text; parentElement.Element("ModifiedBy").Attribute("value").Value = UMSession.CurrentLoggedInUser.UserId.ToString(); parentElement.Element("ModifiedOn").Attribute("value").Value = System.DateTime.Now.ToString(); return rootElement; //rootElement.XPathSelectElement(xPathQuery) = parentElement; } these 2 functions i have used to update xml and to get data from xml and fill into controls. but for the tags where there are multiple records... i am not able to find any solution /control using which i an do it easily. coz my field's value is in attribute named "Value" when in the examples i saw its between opening and closing tag.. i have 2 methods to do so. 1 . i make one page to edit a single record and pass id of record to that page on editing. open the page in iframe on same page to edit and in page_load get data from database for id passed and fill it in control. 2 . i store xml on server as physical file and use it in page i opened in iframe to edit the record. so i am confused... can anybody please guide me that what shpould i do to let user provide interface to edit this xml data/user profile ?
