  • Configuration file for PHP server script

    - by teehoo
    Right now I have a very high volume of requests coming to my webserver which execute a PHP CGI script. Every one of these scripts opens up a config file that I have created to load options of how the script should run. Doing a file I/O operation everytime a request comes in seems very resource intensive to me. I'm not too familiar with the advanced features of PHP, are there any alternatives to achieve what I'm doing?

  • basic json > struct question

    - by danwoods
    I'm working with twitter's api, trying to get the json data from http://search.twitter.com/trends/current.json which looks like: {"as_of":1268069036,"trends":{"2010-03-08 17:23:56":[{"name":"Happy Women's Day","query":"\"Happy Women's Day\" OR \"Women's Day\""},{"name":"#MusicMonday","query":"#MusicMonday"},{"name":"#MM","query":"#MM"},{"name":"Oscars","query":"Oscars OR #oscars"},{"name":"#nooffense","query":"#nooffense"},{"name":"Hurt Locker","query":"\"Hurt Locker\""},{"name":"Justin Bieber","query":"\"Justin Bieber\""},{"name":"Cmon","query":"Cmon"},{"name":"My World 2","query":"\"My World 2\""},{"name":"Sandra Bullock","query":"\"Sandra Bullock\""}]}} My structs look like: type trend struct { name string query string } type trends struct { id string arr_of_trends []trend } type Trending struct { as_of string trends_obj trends } and then I parse the JSON into a variable of type Trending. I'm very new to JSON so my main concern is making sure I've have the data structure correctly setup to hold the returned json data. I'm writing this in 'Go' for a project for school. (This is not part of a particular assignment, just something I'm demo-ing for a presentation on the language)

  • Php mail pulling form data from previous page

    - by Mark
    So I have a form being filled out on one php like so: <p> <label for="first_name">First Name: </label> <input type="text" size="30" name="first_name" id="first_name"/> </p> <p> <label for="last_name"> Last Name:</label> <input type="text" size="30" name="last_name" id="last_name"/> </p> <p> <label for="address_street">Street:</label> <input type="text" size="30" name="address_street" id="address_street"/> </p> <p> <label for="address_city">City:</label> <input type="text" size="30" name="address_city" id="address_city"/> </p> <p> <label for="address_state">State/Province:</label> <input type="text" size="30" name="address_state" id="address_state"/> </p> <p> <label for="email">Your e-mail: </label> <input type="text" size="30" name="email" id="email"/> </p> <p> <label for="phone">Your phone number: </label> <input type="text" size="30" name="phone" id="phone"/> </p> This is on one php page. From here, it goes to another php which part of it contains script to send a html email to recipient. Problem is, I cannot seem to get it to pull the variables even though I thought I declared them correctly and mixed them into the html correctly. <?php $first_name = $_POST['first_name']; $last_name = $_POST['last_name']; $to = "[email protected], [email protected]"; $subject = "HTML email for ALPS"; $message .= ' <html> <body> <div style="display: inline-block; width: 28%; float: left;"> <img src="http://englishintheusa.com/images/alps-logo.jpg" alt="ALPS Language School" /> </div> <div style="display: inline-block; width: 68%; float: right;"> <p style="color: #4F81BD; font-size: 20px; text-decoration: underline;">Thanks You For Your Inquiry!</p> </div> <div style="padding-left: 20px; color: #666666; font-size: 16.8px; clear: both;"> <p>Dear $first_name $last_name ,</p> </br > <p>Thank you for the following inquiry:</p> </br > </br > </br > </br > <p>****Comment goes here****</p> </br > </br > <p>We will contact you within 2 business days. Our office is open Monday-Friday, 8:30 AM - 5:00 PM Pacific Standard Time.</p> </br > <p>Thank you for your interest!</p> </br > </br > <p>Best Regards,</p> </br > </br > <p>ALPS Language School</p> </br > </br > <p>430 Broadway East</p> <p>Seattle WA 98102</p> <p>Phone: 206.720.6363</p> <p>Fax: 206. 720.1806</p> <p>Email: [email protected]</p> </div> </body> </html>'; // Always set content-type when sending HTML email $headers .= "MIME-Version: 1.0" . "\r\n"; $headers .= "Content-type:text/html;charset=UTF-8" . "\r\n"; // More headers mail($to,$subject,$message,$headers); ?> So you see where I am trying to get first_name and last_name. Well it doesn't come out correctly. Can someone help here?

  • C++ Thread level constants

    - by Gokul
    Is there a way by which we can simulate thread level constants in C++? For example, if i have to make a call to template functions, then i need to mention the constants as template level parameters? I can use static const variables for template metaprogramming, but they are process level constants. I know, i am asking a question with a high probability of 'No'. Just thought of asking this to capitalize on the very rare probability :)) Thanks, Gokul.

  • How can I use Three20 to create a dynamic TTThumbsViewController that feeds from a website directory?

    - by Cory Robbins
    Hello, I'm pretty new to the iPhone developing scene, and I am designing an app for a high school band program. Part of the app needs to be an image gallery that retrieves photos from a directory on the band's website and lists them in the thumbnail view. I can't figure out how to create a thumsview that isn't directly linked to specific pictures. I currently have this setup to work with a UIWebView that points to a PHP photo album designed to look like the iPhone Photo Album. This method works, but it is not ideal, and the navigation is obviously a bit less than what would be expected. Is Three20 the right tool for this job? If not, what should I be using? Thanks!

  • Which is the "best" data access framework/approach for C# and .NET?

    - by Frans
    (EDIT: I made it a community wiki as it is more suited to a collaborative format.) There are a plethora of ways to access SQL Server and other databases from .NET. All have their pros and cons and it will never be a simple question of which is "best" - the answer will always be "it depends". However, I am looking for a comparison at a high level of the different approaches and frameworks in the context of different levels of systems. For example, I would imagine that for a quick-and-dirty Web 2.0 application the answer would be very different from an in-house Enterprise-level CRUD application. I am aware that there are numerous questions on Stack Overflow dealing with subsets of this question, but I think it would be useful to try to build a summary comparison. I will endeavour to update the question with corrections and clarifications as we go. So far, this is my understanding at a high level - but I am sure it is wrong... I am primarily focusing on the Microsoft approaches to keep this focused. ADO.NET Entity Framework Database agnostic Good because it allows swapping backends in and out Bad because it can hit performance and database vendors are not too happy about it Seems to be MS's preferred route for the future Complicated to learn (though, see 267357) It is accessed through LINQ to Entities so provides ORM, thus allowing abstraction in your code LINQ to SQL Uncertain future (see Is LINQ to SQL truly dead?) Easy to learn (?) Only works with MS SQL Server See also Pros and cons of LINQ "Standard" ADO.NET No ORM No abstraction so you are back to "roll your own" and play with dynamically generated SQL Direct access, allows potentially better performance This ties in to the age-old debate of whether to focus on objects or relational data, to which the answer of course is "it depends on where the bulk of the work is" and since that is an unanswerable question hopefully we don't have to go in to that too much. IMHO, if your application is primarily manipulating large amounts of data, it does not make sense to abstract it too much into objects in the front-end code, you are better off using stored procedures and dynamic SQL to do as much of the work as possible on the back-end. Whereas, if you primarily have user interaction which causes database interaction at the level of tens or hundreds of rows then ORM makes complete sense. So, I guess my argument for good old-fashioned ADO.NET would be in the case where you manipulate and modify large datasets, in which case you will benefit from the direct access to the backend. Another case, of course, is where you have to access a legacy database that is already guarded by stored procedures. ASP.NET Data Source Controls Are these something altogether different or just a layer over standard ADO.NET? - Would you really use these if you had a DAL or if you implemented LINQ or Entities? NHibernate Seems to be a very powerful and powerful ORM? Open source Some other relevant links; NHibernate or LINQ to SQL Entity Framework vs LINQ to SQL

  • Resize form objects in Java

    - by PeerFull
    I have a Java applet, which is a form that draw shapes into it (Rect, Oval, Line). Each shape is represented by 2 points and can draw itself to the form. When the JApplet form resizes, I need to resize the shapes also while keeping the aspect ratio. I didn't find an high quality solution for doing this that solves this problem. Tried to write a solution from this, but it came up as lousy when tested, Can someone publish an example code for doing that please?

  • Application security issues to consider

    - by user279521
    I am working on the design of a high security application (involving financial information, personal information etc). I need to identify what security measures (application level) will be implemented. The application will involve sending data to and from a database, user login, import export to csv, txt files, and print function. What security features do I need to consider for such an application. (SQL injection for starters) ?

  • X264 encoding using Opencv

    - by user573193
    I am working with a high resolution camera: 4008x2672. I a writing a simple program which grabs frame from the camera and sends the frame to a avi file. For working with such a high resolution, I found only x264 codec that could do the trick (Suggestions welcome). I am using opencv for most of the image handling stuff. As mentioned in this post http://doom10.org/index.php?topic=1019.0 , I modified the AVCodecContext members as per ffmpeg presets for libx264 (Had to do this to avoid broken ffmpeg defaults settings error). This is output I am getting when I try to run the program [libx264 @ 0x992d040]non-strictly-monotonic PTS 1294846981.526675 1 0 //Timestamp camera_no frame_no 1294846981.621101 1 1 1294846981.715521 1 2 1294846981.809939 1 3 1294846981.904360 1 4 1294846981.998782 1 5 1294846982.093203 1 6 Last message repeated 7 times [avi @ 0x992beb0]st:0 error, non monotone timestamps -614891469123651720 = -614891469123651720 OpenCV Error: Unspecified error (Error while writing video frame) in icv_av_write_frame_FFMPEG, file /home/ajoshi/ext/OpenCV-2.2.0/modules/highgui/src/cap_ffmpeg.cpp, line 1034 terminate called after throwing an instance of 'cv::Exception' what(): /home/ajoshi/ext/OpenCV-2.2.0/modules/highgui/src/cap_ffmpeg.cpp:1034: error: (-2) Error while writing video frame in function icv_av_write_frame_FFMPEG Aborted Modifications to the AVCodecContext are: if(codec_id == CODEC_ID_H264) { //fprintf(stderr, "Trying to parse a preset file for libx264\n"); //Setting Values manually from medium preset c-me_method = 7; c-qcompress=0.6; c-qmin = 10; c-qmax = 51; c-max_qdiff = 4; c-i_quant_factor=0.71; c-max_b_frames=3; c-b_frame_strategy = 1; c-me_range = 16; c-me_subpel_quality=7; c-coder_type = 1; c-scenechange_threshold=40; c-partitions = X264_PART_I8X8 | X264_PART_I4X4 | X264_PART_P8X8 | X264_PART_B8X8; c-flags = CODEC_FLAG_LOOP_FILTER; c-flags2 = CODEC_FLAG2_BPYRAMID | CODEC_FLAG2_MIXED_REFS | CODEC_FLAG2_WPRED | CODEC_FLAG2_8X8DCT | CODEC_FLAG2_FASTPSKIP; c-keyint_min = 25; c-refs = 3; c-trellis=1; c-directpred = 1; c-weighted_p_pred=2; } I am probably not setting the dts and pts values which I believed ffmpeg should be setting it for me.

  • what do i need to do now that I want to take programming hobby to next level ?

    - by hohog
    i've always wanted to make games but did not start actively learning programming by myself until 1st year of university. i kept going throughout university learning new languages, showing off things i had made, while neglecting my major in Biology. Anyways, i've ended up with an Economics degree, with a portfolio of SaaS and web apps i had created so i could eat during my final year. So far, I'm getting a few interviews here and there in web programming positions. When I get a logic pretest, I fail miserably. or job requires comp sci degree. I mean I can easily design and code an entire app which I emphasize through my portfolio.... but i dont know why I am so slow at logic puzzles on prescreening interview... So what should I do now ? get certificates in languages ? go back to school and learn CS ? is it too late to get into windows programming jobs than web programming ?

  • Browser based online game question

    - by Emre
    I am developing a small browser based game in asp.net. Think of a game room which has a capaticy of 22 players and players join the room by clicking a button. ( I am saving the number of players in the room in database) I need to call a method when the number of players in the room is 22. The problem is I don't know how to control the number of players in the room. I mean I think like there need to be a bacground code which has to run all the time at the server and that code controls the number and call the function. It's my first web project(school project) and I hope you all can help me.

  • Access to a single pixel in C#

    - by Malki
    Hello, I'm working on a school project right now. It's meant to be a 3D editing software, (like a very minimized version of Maya). I have to write it in C#, using the 'Windows Application Project'. I intend to implement all the 3D stuff myself, from projections to shading. My question is, how can I get direct access to a single pixel in the C# windows application? I know I'm going to have a main view port in the window. But I haven't decided yet how it will be made. Is there a built in object that I can use, that will let me define the boundaries of the view port, and then paint each pixel individually? (I'm just shooting in the dark here, I don't know much about C#. I mostly program in C) Thanks, Malki.

  • License plate recognition

    - by WowtaH
    As a side-project I'm trying to create an app that scans license plates from passing cars from my living-room window. I have hooked up a high resolution camera to my system to capture (moving) images into my c# app. Now all I need is a way to interpret these images into something readable. I´m thinking about some sort of OCR-solution that is fast/accurate enough for moving images. Hope you can give me some direction!

  • Windows Azure: Parallelization of the code

    - by veda
    I have some matrix multiplication operation. I want to parallelize the execution of those operations through multiple processors.. This can be done on high performance computing cluster using MPI (Message Passing Interface). Like wise, can I do some parallelization in the cloud using multiple worker roles. Is there any means for doing that.

  • Why is C++ backward compatible with C ? Why isn't there some "pure" C++ language ?

    - by gokoon
    C and C++ are different languages, blababla we know that. But if those language are different, why is it still possible to use function like malloc or free ? I'm sure there are all sort of dusty things C++ has because of C, but since C++ is another language, why not remove those things to make it a little less bloat and more clean and clear ? Is it because it allows programmers to work without the OO model or because some compilers doesn't support high-level abstract features of C++ ?

  • C: performance of assignments, binary operations, et cetera...

    - by Shinka
    I've heard many things about performance in C; casting is slow compared to normal assignments, functional call is slow, binary operation are much faster than normal operations, et cetera... I'm sure some of those things are specific to the architecture, and compiler optimization might make a huge difference, but I would like to see a chart to get a general idea what I should do and what I should avoid to write high-performance programs. Is there such a chart (or a website, a book, anything) ?

  • Lambda functions

    - by Oden
    Hey, I'm really interested in the way of using lambda functions. Does it make sense to use them in a high-level programming language? If yes, why? Is this really just a function embedded in a function (like this) or is there more behind?
