  • How to use GetActiveUniform (in SharpGL)?

    - by frankie
    Generally, guesting is in header. I cannot understand how to use GetActiveUniform function. public void GetActiveUniform(uint program, uint index, int bufSize, int[] length, int[] size, uint[] type, string name); My attempt looks like this (everything is compiled and linked): var uniformSize = new int[1]; var unifromLength = new int[1]; var uniformType = new uint[1]; var uniformName = ""; Gl.GetActiveUniform(Id, index, uniformNameMaxLength[0], unifromLength, uniformSize, uniformType, uniformName); After call I get proper uniformSize, length and type, but not name.

  • Login and redirect to user home page [migrated]

    - by Rich
    The problem I can't currently solve is when a user logs in. They arrive at the site (index.php) and enter username and password, which gets submitted via a Post form back to index.php - if there are incorrect details then they get an error message. But if successful then I would like them to be taken to their user home page - but I can't do this! I am left presenting them with a link to the home page, which is more than a little clunky. Seems there must be an obviously solution - never seen a site before that didn't redirect! Not sure is the answer is PHp, HTML, or Javascript.

  • Motivation for service layer (instead of just copying dlls)?

    - by BornToCode
    I'm creating an application which has 2 different UIs so I'm making it with a service layer which I understood is appropriate for such case. However I found myself just creating web methods for every single method I have in the BL layer, so the services basically built from methods that looks like this: return customers_bl.Get_Customer_Prices(customer_id); I understood that a main point of the service layer is to prevent duplication of code so I asked myself - well, why not just import the BL.dll (and the DAL.dll) to the other UI, and whenever making a change re-copy the dll files, it might not be so 'neat', but is the all purpose of the service layer to prevent this? {I know something is wrong in my approach, I'm probably missing the importance of service layer, I'd like to get more motivation to create another layer, especially because as it is I found that many of my BL functions ALREADY looks like: return customers_dal.Get_Customer_Prices(cust_id) which led me to ask: was it really necessary to create the BL just because on several functions I actually have LOGIC inside the BL?} so I'm looking for more motivation to creating ONE MORE layer, I'm sure it's not just to make it more convenient that I won't have to re-copy the dlls on changes? Am I grasping it wrong? Any simple guidelines on how to design service layer (corresponding to all the BL layer functions or not? any simple example?) any enlightenment on the subject?

  • How can redirect pages from old core PHP site to new Joomla site?

    - by pkachhia
    We have our old site into core PHP and we have developed it again into Joomla 1.5 last year( because of some limitations we have to build it into 1.5). Now the problem is the URL of sites changed as we have use SEO URLS on joomla. In between we have use .htaccess to redirect user from old URL to new like this Redirect /pages/oldpage.php http://www.mydomain.com/products/category/new_page.html Is this good practice to redirect user to new URL or not?(we have used same server). One more thing, We have used splash page on our site, and to set up it we have made some changes and because of it one of the important link is not working, and it is http://www.mydomail.com/index.php How can I get rid of it? I have used DirectoryIndex splash.html home.html index.php in .htaccess to open splash page first when someone open my site http://www.mydomain.com. Note: my website hosted on dedicated ubuntu server.

  • XNA VertexBuffer.SetData performance suggestions

    - by CodeSpeaker
    I have a 3d world in a grid layout where each grid cell contains its separate vertex and index buffer for the mesh/terrain of that cell. When the player moves outside the boundaries of his cell, i dynamically load more cells in his walking direction based on his viewing distance. This triggers x number of vertex and indexbuffer initializations depending on how many cells that needs to be generated and causes the framerate to drop annoyingly during this time. The generation of terrain data is handled in a separate thread and runs smoothly. The vertex and index buffers are added during the update cycle of the game loop. I´ve tried batching the number of cells to be processed to avoid sending too much data at once into the buffers, which worked ok at a shorter viewing distance (about 9 cells to process), but not as well at greater distances with around 30 cells to process. Any idea how i can optimize this?

  • How to synchronize the ball in a network pong game?

    - by Thaars
    I’m developing a multiplayer network pong game, my first game ever. The current state is, I’ve running the physic engine with the same configurations on the server and the clients. The own paddle movement is predicted and get just confirmed by the authoritative server. Is a difference detected between them, I correct the position at the client by interpolation. The opponent paddle is also interpolated 200ms to 100ms in the past, because the server is broadcasting snapshots every 100ms to each client. So far it works very well, but now I have to simulate the ball and have a problem to understanding the procedure. I’ve read Valve’s (and many other) articles about fast-paced multiplayer several times and understood their approach. Maybe I can compare my ball with their bullets, but their advantage is, the bullets are not visible. When I have to display the ball, and see my paddle in the present, the opponent in the past and the server is somewhere between it, how can I synchronize the ball over all instances and ensure, that it got ever hit by the paddle even if the paddle is fast moving? Currently my ball’s position is simply set by a server update, so it can happen, that the ball bounces back, even if the paddle is some pixel away (because of a delayed server position). Until now I’ve got no synced clock over all instances. I’m sending a client step index with each update to the server. If the server did his job, he sends the snapshot with the last step index of each client back to the clients. Now I’m looking for the stored position at the returned step index and compare them. Do I need a common clock to sync the ball? EDIT: I've tried to sync a common clock for the server and all clients with a timestamp. But I think it's better to use an own stepping instead of a timestamp (so I don't need to calculate with the ping and so on - and the timestamp will never be exact). The physics are running 60 times per second and now I use this for keeping them synchronized. Is that a good way? When the ball gets calculated by each client, the angle after bouncing can differ because of the different position of the paddles (the opponent is 200ms in the past). When the server is sending his ball position, velocity and angle (because he knows the position of each paddle and is authoritative), the ball could be in a very different position because of the different angles after bouncing (because the clients receive the server data after 100ms). How is it possible to interpolate such a huge difference? I posted this question some days ago at stackoverflow, but got no answer yet. Maybe this is the better place for this question.

  • Can I redirect the HTTP request towards an old folder to the homepage using .htaccess file?

    - by AndreaNobili
    I have to following situation: I had an old blog that was made using Joomla (this blog was indexed well enough by search engines). For some problems I delete it and I have create it again using WordPress. Now I have many visit (from Google) that leading to specific pages of the old site (pages that don't exist in the new version). For example I have visit to URL as: /scorejava/index.php/corso-spring-mvc/1-test that don't exist on my new site. I would know if using the .htaccess file (or other sistem) I can redirect the HTTP request directed to some subfolder (that don't exist in the new version) to the homepage of my new site. For example I have the request towards the void URL: /scorejava/index.php/corso-spring-mvc/1-test. And I would create a regular expression that say something like: all the request toward the subfolder corso-spring-mvc (and all it's content file and subfolder) have to be redirected to www.scorejava.com. Is it possible?

  • What makes C so popular in the age of OOP?

    - by GradGuy
    I code a lot both in C and C++ but did not expect C to be the second popular language, slightly behind Java! http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html I'm curious as why, in this age of OOP, C is still all that popular? Note that 4 out of top 5 popular languages are all "modern" object-oriented capable languages. Now I agree that you can do OOP in C to some extend, but that's sort of painful and not quite elegant! (well at least compared to C++ I guess) So what makes C this popular? efficiency? being low-level? or the vast majority of libraries that already exist? ... or something else?

  • How do I add restrictions for users to sign up before they can access web site?

    - by user1867842
    How do I get my webpage not to go back when they hit the back button and are logged out and how can I add a web page to be blocked like FACEBOOK doesn't let you get into their site with out having a page or a account with them, and if you try to put something in the url and try to go to something on their site it gives you a web page that says "you have to be logged in first" . Like I don't want someone going to the url of the "index" page before they have signed up as a member they need to make an account first then they can have access to the "index" page. How do I do this. I have a website so far that has a database and the website has 5 pages so far and two of them which is the login and sign up page which are both used with php and mysql and they work fine. How do I restrict access to the main website by first having the users sign up with me for an account.

  • Configuring httpd.conf to handle wildcard domains and multiple scripts?

    I have a full-blown site like: http://www.example.com (uses index.php) http://www.example.com/scriptA.php http://www.example.com/scriptB.php I now want to have the possibility of setting up subsites like: http://alpha.example.com http://alpha.example.com/scriptA.php http://alpha.example.com/scriptB.php From http://stackoverflow.com/questions/2844004/subdomain-url-rewriting-and-web-apps/2844033#2844033 , I understand that I have to do: RewriteCond %{HTTP_HOST} ^([^./]+)\.example\.com$ RewriteCond %1 !=www RewriteRule ^ index.php?domain=%1 But what about the other scripts like scriptA and scriptB? How do I tell httpd.conf to handle those properly as well? How can I tell httpd.conf that handle everything after the 'forwardslash', exactly as it does on the main site, but pass a parameter flag like ?domain=alpha (Cross posted at: http://stackoverflow.com/questions/11365566/configuring-httpd-conf-to-handle-wildcard-domains-and-multiple-scripts)

  • Javascript Only Search Method [on hold]

    - by user2118228
    I need to put a search function on a website that is going to be on a CD-ROM with no access to the internet. It has 80 pages, and about 500 'items', so I'd prefer to not have to hard code 100's of 'if statements if possible. I've found a few programs you can buy that will index and generate results (Zoom Search, JSS Index, The German Guys') but there are odd quirks with each one. Plus I would rather code it myself to get complete control over it, and to really understand what it's doing. Basically searching for a few words would display the product image and description; clicking on that would take you the related URL. This is kind of complicated, I can't find an easy solution not dealing with hundreds of if Statements. Has anyone ever created anything like this or know a better method? I'm not really sure a better way to go about this. I've used PHP/MYSQL for search results before, but this cannot run any php.

  • Redirecting to a default (or last visited) subdirectory. Does Google like this?

    - by andufo
    i have a site that has 3 web applications, lets use this example: example.com/nicy example.com/mash example.com/zoken The main application is nicy, so if the user comes for the first time (or if Google indexes my site) that will be the default choice. This is the code placed inside example.com/index.php <? header('HTTP/1.1 301 Moved Permanently'); header('Location: http://example.com/nicy'); die(); ?> Is this solution SEO friendly for Google to index the nicy subdirectory as the main entrance page for the domain? (because of the 301 redirect). Thanks!

  • 301 redirect from a country specific domain

    - by Raj
    I originally started using a .do domain extension for my site, but later realized that this country specific domain would prevent us from appearing in search results for places outside of the Dominican Republic. We started using a .co domain extension and redirected all requests to the new domain using an HTTP 301. The "Crawl Stats" in Google Webmaster Tools shows me that the .co domain is being crawled, but the "Index Status" shows the number of pages indexed at 0. The "Crawl Stats" for the .do domain says that it's being crawled and the "Index Status" shows a number greater than 0. I also set a "Change Of Address" in Google Webmaster Tools to have the .do domain point to the new .co domain. We're still not appearing in search results at all even for very specific strings where I would expect to find us. Am I doing something wrong?

  • In addition to Google's First Flick Free, should you whitelist search engine bots past a paywall?

    - by tobek
    Our site has subscription-only pages - non-subscribed visitors see a snippet preview. As per Google's FCF requirements, your first 5 hits to a subscriber-only pages with .google. as the referrer, you see the full page. In addition to this, should we whitelist search engine bots so that they can index the full content? I assume this is not required for Google, which can use FCF to index our content, but what about other search engines? Is this considered cloaking? My gut says that whitelisting bots past the paywall is bad practice., but I wanted to confirm - any evidence or references would be amazing.

  • Domain Specific Software Engineering (DSSE)

    Domain Specific Software Engineering (DSSE) believes that creating every application from nothing is not advantageous when existing systems can be leveraged to create the same application in less time and with less cost.  This belief is founded in the idea that forcing applications to recreate exiting functionality is unnecessary. Why would we build a better wheel when we already have four really good and proven wheels? DSSE suggest that we take an existing wheel and just modify it to fit an existing need of a system. This allows developers to leverage existing codebases so that more time and expense are focused on creating more usable functionality compared to just creating more functionality. As an example, how many functions do we need to create to send an email when one can be created and used by all other applications within the existing domain? Key Factors of DSSE Domain Technology Business A Domain in DSSE is used to control the problem space for a project. This control allows for applications to be developed within specific constrains that focus development is to a specific direction.Technology in DSSE offers a variety of technological solutions to be applied within a domain. Technology Examples: Tools Patterns Architectures & Styles Legacy Systems Business is the motivator for any originations to use DSSE in there software development process. Business reason to use DSSE: Minimize Costs Maximize market and Profits When these factors are used in combination additional factors and benefits can be found. Result of combining Key Factors of DSSE Domain + Business  = Corporate Core Competencies Domain expertise improved by market and business expertise Domain + Technology = Application Family Architectures All possible technological solutions to problems in a domain without any business constraints.  Business + Technology =  Domain independent infrastructure Tools and techniques for building systems  independent of all domains  Domain + Business + Technology = Domain-specific software engineering Applies technology to domain related goals in the context of business and market expertise

  • Finding "Stuff" In OUM

    - by Dave Burke
    One of the first questions people asked when they start using the Oracle Unified Method (OUM) is “how do I find X ?” Well of course no one is really looking for “X”!! but typically an OUM user might know the Task ID, or part of the Task Name, or maybe they just want to find out if there is any content within OUM that is related to a couple of keys words they have in their mind. Here are three quick tips I give people: 1. Open up one of the OUM Views, then click “Expand All”, and then use your Browser’s search function to locate a key Word. For example, Google Chrome or Internet Explorer: <CTRL> F, then type in a key Word, i.e. Architecture This is fast and easy option to use, but it only searches the current OUM page 2. Use the PDF view of OUM Open up one of the OUM Views, and then click the PDF View button located at the top of the View. Depending on your Browser’s settings, the PDF file will either open up in a new Window, or be saved to your local machine. In either case, once the PDF file is open, you can use the built in PDF search commands to search for key words across a large portion of the OUM Method Pack. This is great option for searching the entire Full Method View of OUM, including linked HTML pages, however the search will not included linked Documents, i.e. Word, Excel. 3. Use your operating systems file index to search for key words This is my favorite option, and one I use virtually every day. I happen to use Windows Search, but you could also use Google Desktop Search, of Finder on a MAC. All you need to do (on a Windows machine) is to make sure your local OUM folder structure is included in the Windows Index. Go to Control Panel, select Indexing Options, and ensure your OUM folder is included in the Index, i.e. C:/METHOD/OM40/OUM_5.6 Once your OUM folders are indexed, just open up Windows Search (or Google Desktop Search) and type in your key worlds, i.e. Unit Testing The reason I use this option the most is because the Search will take place across the entire content of the Indexed folders, included linked files. Happy searching!

  • Simple mod_rewrite Question

    - by user5358
    Hello, I want to have everything that looks like this: /1/2/3/4/5/[...] to redirect to this: /index.php?u=/1/2/3/4/5/[...] unless the requested string is a specific file. So anything that doesn't have a ".", I want to redirect to "index.php?u=[...]". I'll then parse the URI segments in PHP to determine what the user is requesting. I've been looking around for how to do this, but have only a very rough understanding of regular expressions and have been unable to find an example of how to do it. Thanks!

  • How does one redirect from one wordpress page to another via htaccess?

    - by jchwebdev
    I tried making the following change to my wordpress site to permanently redirect a common link to a new page. I could've -sworn- that this used to work. But it simply does not (at least in WP 3.9). I have had to resort to using a Redirect Plug-In. I'm wondering -why- it doesn't work and if there is a technique which -will- work. I'd prefer to continue to use .htaccess for simplicity. Below is the .htaccess file: # MY CHANGES Redirect 301 http://mysite.com/gigs http://mysite.com/booking/ # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> Again, it works by using a redirect plug-in inside WP, but there must be a way to force the 'redirection' to occur -before- the URL is passed to the WP engine, right? How is the done?

  • .htaccess two different rules but only one per time

    - by dragon112
    I'm rather new to the whole .htaccess thing and I'm using the following right now to use 'pretty url's': <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?path=$1 [NS,L] </IfModule> Now i found my website a bit slow and decided to start gzipping my CSS files thru a php script I found somewhere on the web (the website). For this to work I need to rewrite the url to open the correct php file. That would look something like this: RewriteRule ^(.*).css$ /csszip.php?file=$1.css [L] But I only want the first to happen when the second doesn't and vice versa. In other words i'd like something like this: <IfModule mod_rewrite.c> RewriteEngine On if request doesn't contain .css do RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?path=$1 [NS,L] else do RewriteRule ^(.*).css$ /csszip.php?file=$1.css [L] </IfModule> Can anyone help me with the proper code or a place where i can find a way to use some kind of conditional statement in htaccess files? Thanks in Advance!:)

  • Are areas a good organizational feature, or just extra work?

    - by SOfanatic
    Do Areas in ASP.NET MVC end up being a help or just a drag in the end (because of the URL construction)? Would it be better to have subdirectories inside the main Controllers folder? or are there any other options to organizing a project? EDIT For example, this is your average link without Areas: @Html.ActionLink("Home","Index","Home") and this is your average link with Areas: @Html.ActionLink("Home","Index", new { Area = "", Controller = "Home"}) Could the following work? (Main controller with subdirectories) I'm just trying to find out if implementing Areas in a project is worthwhile, because I also read that it can be problematic when using Dependency Injection. And is there an alternative to Areas?
