  • How to make software which will work like torrent?

    - by Nitz
    Hey guys How to make software work like torrent work? Bcz always when i see that torrent software then i am really amazed by their sizes and what they do in that sizes? How they managed the download by parts and then all together as soon as u downloaded full part? and as soon as you had great speed then your download speed automatically goes up? How to make software which will work like torrent means peer-to-peer? how to make this kind of software which can download from different servers and managed to know each users download and upload? and how they have pretty small size? which tech. they have used in that kind of software? Sorry i had asked many question. I know how downloading is happening means peer-to-peer all that.. but i don't know how they have built that kind of thing?

  • I have a bunch of divs floated left, lined up in columns with different heights. They dont create a

    - by Roeland
    Hey guys, I am trying to create a grid like system with div's with content floated left. The problem is that the height of each div is not static since the content is different in each one. Since the height is different.. things get outta whack if one is taller then another in one row. Is there some sort of css way or js (prefer javascript) way to get around this. I really want to avoid setting large heights on the divs to get them to line up. You can see the example here: http://www.foreclosurejournalinc.com/index.php?option=com_hotproperty&view=type&id=1

  • Develop applications to mobiles

    - by muek
    Hi there, I have very easy question, but I simply have any idea of the answer. I have developed a small mobile-application using java, for my nokia. The problem is that when installed on my samsung the application simply crashed. Then I tried on my other nokia but different model, and I didn't got the normal behavior. So my question is, does anyone have any idea how companies that develop mobiles applications/games test their software. Does they have to have all models for all mobiles phones??

  • Spring MVC working with Web Designers

    - by jboyd
    When working with web-designers in a Spring-MVC and JSP environment, are there any tools or helpful patterns to reduce the pain of going back and forth from HTML to JSP and back? Project requirements dictate that views will change often, and it can be difficult to make changes efficiently because of the amount of Java code that leaks into the view layer. Ideally I'd like to remove almost all Java code from the view, but it does not seem like this works with the Spring/JSP philosophy where often the way to remove Java code is to replace that code with tag libraries, which will still have a similar problem. To provide a little clarity to my question I'm going to include some existing code (inherited by me) to show the kinds of problems I'm likely to face when change the look of our views: <%-- Begin looping through results --%> <% List memberList = memberSearchResults.getResults(); for(int i = start - 1; i < memberList.size() && i < end; i++) { Profile profile = (Profile)memberList.get(i); long profileId = profile.getProfileId(); String nickname = profile.getNickname(); String description = profile.getDescription(); Image image = profile.getAvatarImage(); String avatarImageSrc = null; int avatarImageWidthNum = 0; int avatarImageHeightNum = 0; if(null != image) { avatarImageSrc = image.getSrc(); avatarImageWidthNum = image.getWidth(); avatarImageHeightNum = image.getHeight(); } String bgColor = i % 2 == 1 ? "background-color:#FFF" : ""; %> <div style="float:left;clear:both;padding:5px 0 5px 5px;cursor:pointer;<%= bgColor %>" onclick='window.location="profile.sp?profileId=<%= profileId %>"'> <div style="float:right;clear:right;padding-left:10px;width:515px;font-size:10px;color:#7e7e7e"> <h6><%= nickname %></h6> <%= description %> </div> <img style="float:left;clear:left;" alt="Avatar Image" src="<%= null != avatarImageSrc && avatarImageSrc.trim().length() > 0 ? avatarImageSrc : "images/defaultUserImage.png" %>" <%= avatarImageWidthNum < avatarImageHeightNum ? "height='59'" : "width='92'" %> /> </div> <% } // End loop %> Now, ignoring some of the code smells there, it's obvious that if someone wants to change the look of that DIV it would be neccesary to re-place all the Java/JSP code into the new HTML given (the designers don't work in JSP files, they have their own HTML versions of the website). Which is tedious, and prone to errors.

  • UIImageView "Sprite Movement" How?

    - by Tate Allen
    Hi all, I am trying to make a game for the iPhone/iPod Touch. I am somewhat new to iPhone programming and extremely new to iPhone game programming so try to bear with me if this is a stupid question. How to I make my character, a UIImageView, move to the right or left, along the x axis. Just a simple translation across the screen. This is very frustrating so if you could link me to a tutorial or something like that, it would be much appreciated. Thanks in advance, Tate

  • Modelling deterministic and nondeterministic data separately

    - by Superstringcheese
    I'm working with the Microsoft ADO.NET Entity Framework for a game project. Following the advice of other posters on SO, I'm considering modelling deterministic and nondeterministic data separately. The idea for this came from a discussion on multiplayer games, but it seemed to make sense in a single-player scenario as well. Deterministic (things that aren't going to change during gameplay) Attributes (Strength, Agility, etc.) and their descriptions Skills and their descriptions and requirements Races, Factions, Equipment, etc. Base Attribute/Skill/Equipment loadouts for monsters Nondeterministic (things that will change a lot during gameplay) Beings' current AttributeModifers (Potion of Might = +10 Strength), current health and mana, etc. Player inventory, cash, experience, level Player quests states Player FactionRelationships ...and so on. My deterministic model would serve as a set of constants. My nondeterministic model would provide my on-the-fly operable data and would be serialized to a savegame file to maintain game state between play sessions. The data store will be an embedded SQL Compact database. So I might want to create relations between my Attributes table (deterministic model) and my BeingAttributeModifiers table (nondeterministic model), but how do I set that up across models? Det model/db Nondet model/db ____________ ________________________ |Attributes | |PlayerAttributeModifiers| |------------| |------------------------| |Id | |Id | |Name | |AttributeId | |Description | |SourceId | ------------ |Value | ------------------------ Should I use two separate models (edmx) that transact with a single database containing both deterministic-type and nondeterministic-type tables? Or should/can I use two separate databases in one model? Or two models each with their own database? With distinct models/dbs it seems like this will get really complicated and I'll end up fighting EF a lot, rolling my own transaction code, and generally losing out on a lot of the advantages of the framework. I know these are vague questions, I'm just looking for a sanity check before I forge ahead any further.

  • What first game did you program, and did it make you a better developer?

    - by thenonhacker
    What first game did you program? Name your game, the OS and language, and even a Website URL to get your game. Old DOS Games and Flash Games with ActionScript are allowed. Game kits are allowed, too. ...and did it make you a better developer? Programming games can be addicting, and it will bring out the best in us as we create our first game. What lessons did you learn form most? Algorithm and/or AI's? Graphics? User Interface? File Formats and Data Storage? Project and Time Management? Can you say that because you practiced programming by creating this game, you became more immersed with the programming language you used and helped you become a better developer?

  • Struggling with ASP.NET MVC auto-scaffolder template

    - by DanM
    I'm trying to write an auto-scaffolder template for Index views. I'd like to be able to pass in a collection of models or view-models (e.g., IQueryable<MyViewModel>) and get back an HTML table that uses the DisplayName attribute for the headings (th elements) and Html.Display(propertyName) for the cells (td elements). Each row should correspond to one item in the collection. Here's what I have so far: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> <% var items = (IQueryable<TestProj.ViewModels.TestViewModel>)Model; // How do I make this generic? var properties = items.First().GetMetadata().Properties .Where(pm => pm.ShowForDisplay && !ViewData.TemplateInfo.Visited(pm)); %> <table> <tr> <% foreach(var property in properties) { %> <th> <%= property.DisplayName %> </th> <% } %> </tr> <% foreach(var item in items) { HtmlHelper itemHtml = ????; // What should I put in place of "????"? %> <tr> <% foreach(var property in properties) { %> <td> <%= itemHtml.Display(property.DisplayName) %> </td> <% } %> </tr> <% } %> </table> Two problems with this: I'd like it to be generic. So, I'd like to replace var items = (IQueryable<TestProj.ViewModels.TestViewModel>)Model; with var items = (IQueryable<T>)Model; or something to that effect. A property Html is automatically created for me when the view is created, but this HtmlHelper applies to the whole collection. I need to somehow create an itemHtml object that applies just to the current item in the foreach loop. I'm not sure how to do this, however, because the constructors for HtmlHelper don't take a Model object. How do I solve these two problems?

  • Web based weekly planner

    - by Calum
    Hello I'm looking to implement a web based weekly planner where a user can set when they will be unavailable to work. The state of the week will be saved as a 'varbinary' with a length of 168 which will represent every hour of everyday of a week. The database only needs to store the value of one week as the times unavailable to work will be the same each week. I'm looking for a quick and effective method, possibly based on jquery. Thanks

  • Postback problem downloading zip file

    - by Chris Conway
    I've got a problem on a webforms application where a user selects some criteria from dropdowns on the page and hits a button on the page which calls this method: protected void btnSearch_Click(object sender, EventArgs e) They then click on button to download a zip file based on the criteria which calls this method: protected void btnDownload_Click(object sender, EventArgs e) In IE, they are prompted with the bar at the top of the browser that tells them "To help protect your security, Internet Explorer blocked this site from downloading files to your computer". When they click on that bar to download the file, it fires the btnSearch_Click event again. Response.ContentType and Response.AddHeader has been set up correctly. The problem is, that btnSearch appends criteria so basically it is being appended twice and causing problems. Is there something I can do to prevent this? This is a vs2008 web app using c# 3.5 for what it's worth. Thanks!

  • ImageMagick - how to enforce min/max heights/widths?

    - by Henryh
    Using ImageMagick, how can I resize an image to have a minimum: height of 150px width of 200px and also have a maximum: height of 225px width of 275px UPDATE: In case it helps, here's a further explanation of what I'm experiencing. I have a buch of images with all different ratio dimensions. Some images have 1:5 height/width ratios. Some have 5:1 height/width ratios. So that I want to do is set that a minimum height/width size for the image but also don't want the image size to be larger than a particular size. If I need to apply white padding to an image to make it fit within my constraint so that I don't have to distort the image, I'd like to do so.

  • Webfaction apache + mod_wsgi + django configuration issue

    - by Dmitry Guyvoronsky
    A problem that I stumbled upon recently, and, even though I solved it, I would like to hear your opinion of what correct/simple/adopted solution would be. I'm developing website using Django + python. When I run it on local machine with "python manage.py runserver", local address is http://127.0.0.1:8000/ by default. However, on production server my app has other url, with path - like "http://server.name/myproj/" I need to generate and use permanent urls. If I'm using {% url view params %}, I'm getting paths that are relative to / , since my urls.py contains this urlpatterns = patterns('', (r'^(\d+)?$', 'myproj.myapp.views.index'), (r'^img/(.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT + '/img' }), (r'^css/(.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT + '/css' }), ) So far, I see 2 solutions: modify urls.py, include '/myproj/' in case of production run use request.build_absolute_uri() for creating link in views.py or pass some variable with 'hostname:port/path' in templates Are there prettier ways to deal with this problem? Thank you. Update: Well, the problem seems to be not in django, but in webfaction way to configure wsgi. Apache configuration for application with URL "hostname.com/myapp" contains the following line WSGIScriptAlias / /home/dreamiurg/webapps/pinfont/myproject.wsgi So, SCRIPT_NAME is empty, and the only solution I see is to get to mod_python or serve my application from root. Any ideas?

  • What things on a job listing should be avoided?

    - by Earlz
    Hello, I'm looking at trying my hand at a bit of freelancing. And looking at some of the listings, I can tell some of them are definitely, obviously wrong. "A web application mimicking youtube. Project must be completed in 2 weeks. Flat payment of $200. If you are not willing to do things this fast paced then do not apply" But some of them are more subtle and they give me a red flag inside, but I'm not sure to avoid them. What are some things in job listings to avoid for freelance programming jobs? What is the reason for avoiding that?

  • Basic Contact Form in PHP

    - by NessDan
    I'm working on a contact form for my church website. The church has an email already registered (it's POP3) and the hosting company says their mail server is mymail.brinkster.com . With all that information, how can you send the form using mail()? The server won't show PHP errors. The current code looks like this: $headers = 'MIME-Version: 1.0' . "\r\n"; $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n"; $headers .= 'From: *ChurchsEmail*' . "\r\n"; if(mail("*MyEmailHere*", "Setting Up PHP Email", "This would be the body of the email.", $headers)) { echo "The email was successfully sent."; } else { echo "The email was NOT sent."; } All I get back is "The email was NOT sent." So does anyone have any experience setting up an email form like this? My thanks to anyone who can help me out and any efficient ways of doing this, let me know!

  • How to determine what in my script is blocking my HTML rendering?

    - by Vicki
    I have a web application that uses quite a bit of JavaScript. When the page loads, it's very clear visually that something is blocking the rendering of a particular portion of the web site. This portion is generated by a Tabber Tabify JavaScript library. How can I determine what's blocking the HTML rendering specifically so that I can modify my code to prevent this blocking? Can I use Firebug, or some other tool, to walk through my HTML/JavaScript to determine where the HTML rendering is being blocked and if so, how? UPDATE: YSlow gives my web-application a score of "A" and Page Speed give a score of 94/100. UPDATE 2: The live site is linked below. http://www.uptownelite.com/index.uncompressed.html?city=Dallas,TX What I'm specifically referring too is the actual Tabs themselves being rendering (and NOT the panel content inside the tab panes). It seems strange to me that the Tab headings themselves are taking so long to generate on the first (empty cache) page load.
