• Game Server Language Selection

  - by mr.LiKaShing

  I am planning to make a online-multiplayer game with my friends. The game is a browser card game (so, players act in turns) and players could host rooms in a lobby. Flex + actionscript will be used to write for the client side. We are discussing what should be used for the server side. I suggested C#/Java and my friend suggested PHP. I kw there are couple of questions asking for what language to use but I think it should depend on specific conditions. Is there any suggestion for us? Thanks.

• Different characters take more/less data?

  - by Nathan

  I am working on a personal project and I'm wondering if certain characters take up more data in a text file than others. I need to choose a character to seperate items in my file, but if a 0 uses less bytes than a ! or something, it would be best to do that. I know all characters have an ASCII value, but would a lower ASCII value mean the character can be stored in fewer bytes? This might be an incredibly stupid question, but I don't see any information on the topic online so I came here to check. Thanks!

• Mongodb, simple IN problem

  - by afvasd

  Hi everyone I am new to mongo, this is my db design: product := { name: str group: ref, comments: [ ref, ref, ref, ref ] } comments := { ... a bunch of comments stuff } tag := { _id: int, #Need this for online requests tag: str, products: [ {product: ref, score: float}, ... ], comments: [ {comment: ref, score: float}, ...], } So my usage pattern is: GIVEN a product, find comments that have certain tag and sort them accordingly. My current approach involves: Look for that tag object that has tag=myTag pull all the comments out, sorted look for that product where product.name=myProduct pull all the comments out (which are dbrefs by the way) loop through the result of 2, and checking if they are in 4, (this I can do a limit 10) etc. It's pretty inefficient. Any better methods?

• Mobile web apps - Is this the right approach?

  - by Pasta

  I need to build a cross platform mobile app (iphone, android, etc). The app is for a company like a cellular operator (Tmobile, ATT). The app needs to do the following: Show previous bills (cached so that it does not have to download everytime) Need an internet connection to download newer bills, view recent data, etc. Can I build a mobile web app to handle this? I understand that there is offline storage and iPhone has good support for web apps (full screen, good icons, offline, etc). Will a web app be the best approach to take as the app requires to be online? The app will not be used by lots of people, just customers of the website who don't want to use an existing website. We are all web developers and a mobile web app looks like the best way to approach this.

• RSpec "undefined local variable or method `user'"

  - by Justin

  I have the following test written in RSpec: describe '#create' do ... it 'redirects users to profile page' do response.should redirect_to user_path(user) end ... ... And the following in my UsersController: def create @user = User.new(params[:user]) if @user.save redirect_to user_path(@user) end end Does anyone know why this is returning the following error: NameError: undefined local variable or method 'user' I also tried changing this to be root_url in both cases instead of user_path(user) and it gave a different error saying: Expected response to be a <:redirect>, but was <200> Does anyone know what the issue might be? I have double-checked my code and have seen similar questions posted online, but haven't been able to find a solution. Thanks in advance for any help!

• Reading in MIPS external file so another file can use it?

  - by SkyWookie

  Hey all, I'm working on this final thing for my MIPS project and it's deceptively easy. I need to get a procedure (called feed) and let its main driver program use it by reading it in. I know that I'm supposed to use the call code 14 and .globl sym (I think) in order to feed it into the file and have it read it. I just need a basic tutorial or something, as I CANNOT find it on the Internet or in my book (just lists the call code, real helpful). Here's what I know: I need to use read, but I also need a file descriptor (don't know where to get it). I need to put the buffer in $a1 and the length in $a2. Well, that's about it. If there's any decent tutorial you could whip up or if there is one online that I don't see let me know please :). I just need a push in the right direction, I'm sure it can't be too difficult, just can't find any info on it!

• Basic iphone timer example

  - by Rob

  Okay, I have searched online and even looked in a couple of books for the answer because I can't understand the apple documentation for the NSTimer. I am trying to implement 2 timers on the same view that each have 3 buttons (START - STOP - RESET). The first timer counts down from 2 minutes and then beeps. The second timer counts up from 00:00 indefinitely. I am assuming that all of the code will be written in the methods behind the 3 different buttons but I am completely lost trying to read the apple documentation. Any help would be greatly appreciated.

• Creating a file/folder structure and zipping it up?

  - by makeee

  I have a directory of image files and I need a php script or shell script that will rename them, create a structure of nested directories, and then insert each image into a specified place in the directory hierarchy. Ideally I would just specify a parent directory for each file and a parent directory for each directory and it would build it. And then finally, I need the script to zip up the whole thing. There's probably not an existing php class that will do all this for me, but if anyone knows of a php class or other script available online that would handle a lot of this logic that would be great.

• A server-side language to Learn

  - by Roth

  I'm a graphic designer, with experience in print design. In fact, I'm working on digital prepress since 4 years ago. I'm doing a course on web design right now, although I have been studying it on my own for a while, online. So, my question is, what kind of server-side language do I need to learn? I'm feel comfortable with HTML, CSS, and Javascript, even with preprocessors like SASS and LESS, but server-side scripting becomes a nightmare to me. So, what kind of language is necessary to learn? Any book or resource to that specific language? Thanks a lot for your answers.

• Run command with no terminal output

  - by Insomaniacal

  Hello, I've searched around online, but can't find the answer to my question. What I want to do is run a command in pythong, using the subprocess module, and store the output in a variable. However, I do not want the command's output to be printed to the terminal. For this code: def storels(): a = subprocess.Popen("ls",shell=True) storels() I get the directory listing in the terminal, instead of having it stored in a. I've also tried def storels(): subprocess.Popen("ls > tmp",shell=True) a = open("./tmp") [Rest of Code] storels() This also prints the output of ls to my terminal. I've even tried this command with the somewhat dated os.system method, since running "ls tmp" in the terminal doesn't print ls to the terminal at all, but stores it in tmp. However, the same thing happens. I'm using python 2.6. Any suggestions? Thanks in advance!

• How to Best Setup a Website Project in VS.NET

  - by Jason

  I have very little experience with setting up a website from scratch in a .NET environment. As I am doing this now, I am wondering - what's the best way to go? Is it better to create a new Website Project, and include the various backend services and database code as part of that project, or is it better to split out the various aspects of the project? If the second, how would I go about doing that? I want to ensure that this project is easy to manage in the future (in terms of source control, deployment, etc), so I want to make sure I'm starting off on the right foot. I was unable to find any tutorials online, but if you have any, I would appreciate those as well. Thanks!

• MySql database design for a quiz

  - by Mark

  I'm making an online quiz with php and mysql and need a bit of help deciding how to design the database for optimal insert of questions/answers and to select questions for the quiz. The table will hold 80 questions each with 4 possible options plus the correct answer. When retrieving the questions and options from the database I will randomly select 25 questions and their options. Is it better to make a single column for all questions, options, and correct answers? For example: ID | Q | OPT1 | OPT2 | OPT3 | OPT4 | ANS Or would it be better to make a column for each individual question, option, and correct answer? For example: Q1 | Q1_OPT1 | Q1_OPT2 | Q1_OPT3 | Q1_OPT5 | Q1_ANS | Q2 | Q2_OPT1 | Q2_OPT2...

• What's the best way to convert a date and time into a timestamp using php?

  - by user1267980

  I need to convert a date and time into a timestamp with php. The following code shows what I'm currently using: <?php $date="2012-06-29 10:50"; $timestamp = strtotime($date); echo $timestamp; ?> However, when I test the timestamp in an online convertor (http://www.epochconverter.com), the resulting date is 29th June 2012, 8:50, or 2 hours previous. Is it possible that the strtotime() function isn't completely accurate and is just an estimate of the time? If so, are there better methods I could use for getting the exact time? Thanks.

• receive xml file as a parameter to a .net web service

  - by fizch

  My company is currently looking into bringing a new piece of third party software in for online ordering. The software does not handle pricing so they are requesting the pricing information from a web service. Their software is passing an XML file as a parameter, and expecting an XML file as a response. I would think that returning an XML file would be pretty straight forward, but I cannot think of a way to receive an XML file as a parameter. Has anyone done this, or am I missing something really obvious?

• VS2010 (older) installer project - two or more objects have the same target location.

  - by Hamish Grubijan

  This installer project was created back in 2004 and upgraded ever since. There are two offending dll files, which produce a total of 4 errors. I have searched online for this warning message and did not find a permanent fix (I did manage to make it go away once until I have done something like a clean, or built in Release, and then in Debug). I also tried cleaning, and then refreshing the dependencies. The duplicated entries are still in there. I also did not find a good explanation for what this error means. Additional warnings are of this nature: Warning 36 The version of the .NET Framework launch condition '.NET Framework 4' does not match the selected .NET Framework bootstrapper package. Update the .NET Framework launch condition to match the version of the .NET Framework selected in the Prerequisites Dialog Box. So, where is this prerequisites box? I want to make both things agree on .Net 4.0, just having a hard time locating both of them.

• Are free and open source templates, themes, self content management systems replacing the need of we

  - by metal-gear-solid

  Are free and open source templates, themes, self content management systems replacing the need of web designers? You can find templates online for pretty much anything these days. There are html and css templates, templates for Wordpress, all sorts of different cms templates, e-ecommerce templates, etc. Many of these are pretty cheap and some are even free, so where do web designers fit into this picture? I’ve had many clients and potential customers ask why they should use my services instead of just buying a cheap template. Are web designers being replaced?

  Hi I am setting up a small website sort of like an online portfolio. I made the mistake of signing up for shared-web hosting before asking if they supported stored procedures which took me half the day to figure out they didn't. Basically i'm looking for a site that offers me PHP5.4+/ Mysql 5.5 + with support for triggers/stored procedures/ and if possible MyphpAdmin 3.5.1. I also have a domain name I already registered and which I would like to use. What is my best option to look for hosting provider which offers this functionality or to setup a VPS?

• Can I sell video and music in iPhone app via in-app purchase

  - by initialz

  Hi, I'm going to sell some video and music (which I have right to use and sell) in iPhone app. But I'm not sure whether this is allowed by Apple. The plan is to create a consumable in-app purchase product and ask user to pay it when visit the individual video page. After successful purchase, user can download or view it online without any limitation. Server side will also remember the purchase status so the user won't be asked to pay when he visit this vide page next time. So, does anyone have experience on this kind of business and give me some suggestions? Thanks a lot!

• how to detect an F5 refresh keypress event in jquery?

  - by chaonextdoor

  I noticed that jquery has a keypress function. But it seems that it can only detect keypress event of numbers and characters. It cannot detect the F5 keypress event. And What surprises me the most is everyone online says that the keyCode of F5 is 116, But when I use the jquery keypress function, it just shows that the character t has the keyCode of 116(it seems that 116 is the ascii code of lowercase t)! Can somebody give me any idea about this and how to detect the F5 event in javascript or jquery? Thanks so much in advance.

• what is the best approach for to use openGL in the web?

  - by Y_Y

  I wrote a program in C++/OpenGL (using Dev-C++ compiler) for my calculus 2 class. The teacher liked the program and he requested me to somehow put it online so that instead of downloading the .exe file and run it the web browser will run it automatically just like a java applet. The question is: How if possible, can I display a C++/OpenGL program in a web browser? I am thinking of moving to JOGL which is a java interpretation of OpenGL but I rather stay in C++ since I am more familiar with it. Also is there any other better and easier 3D web base API that I can consider?

• Beginner's Language app

  - by Eiseldora

  Hi I'm a techie with no programing experience. I know html and css, but I'd like to someday be able to make an app for my phone (I have an android) and possibly mobile websites. I made learning a programing language and creating a mobile app a goal for my job, and now my boss would like me to pick a programing language to learn. I found a free open course from MIT (http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-00-introduction-to-computer-science-and-programming-fall-2008/) called introduction to computer science. In the course they teach python, but more importantly it seems they teach how to think like a programmer. When I told my boss about the free online course she didn't think that Python was an appropriate language for me to learn. She'd like me to learn a language that is more similar to one used to make Phone apps. Does anyone out there know a better language for me to pick up that would be similar to Android or iPhone's App language. Thank you
