• best way to make this app/website combo?

  - by mharris7190

  I have an idea for an app that lets different bars upload drink specials via a webpage to that app. They would log in the website, and the website would prompt them with a box to input the drink specials. When they are done, the app pulls the information and creates a card for that bar. The app would launch into a week view where you select the day you want to see specials for. After the day is selected, it brings you to a scroll view with different bars' cards laid out vertically, each taking up the width of the screen, allowing the user to scroll through the deals for that day of the week. How should I go about doing this if I have very little programming experience? Is there any convention in doing an app like this? Can anyone suggest any reading material that would help? Thank you!

• Usage examples of binary search

  - by python dude

  I just realized that in my 4+ years of Java programming (mostly desktop apps) I never used the binary search methods in the Arrays class for anything practical. Not even once. Some reasons I can think of: 100% of the time you can get away with linear search, maps or something else that isn't binary search. The incoming data is almost never sorted, and making it sorted requires an extra sorting step. So I wonder if it's just me, or do a lot of people never use binary search? And what are some good, practical usage examples of binary search?

• how to copy an array into somewhere else in the memory by using the pointer

  - by user2758510

  I am completely new in c++ programming. I want to copy the array called distances into where pointer is pointing to and then I want to print out the resul to see if it is worked or not. this is what I have done: int distances[4][6]={{1,0,0,0,1,0},{1,1,0,0,1,1},{1,0,0,0,0,0},{1,1,0,1,0,0}}; int *ptr; ptr = new int[sizeof(distances[0])]; for(int i=0; i<sizeof(distances[0]); i++){ ptr=distances[i]; ptr++; } I do not know how to print out the contents of the pointer to see how it works.

• What is the best way to start building a Web 2.0 / Start up?

  - by spyhunterx

  I'm planning on developing my own web 2.0 application from scratch, using Yii Framework, JQuery, and HTML5 Boilerplate or Boots Strap. But I have huge dilemma. To begin this web 2.0, where is it best to start ? I've already completed flowcharts, diagrams and descriptions sheets for my project; However, i'm stuck programming and design wise. Should I start with the CSS of the the website, Photoshop, or functionality ( Php ) ? Where should I start ? I would really love this start up to be a success. I will greatly appreciate some responses.

• Explanation of NSMutableURLRequest : setHTTPMethod

  - by kkmoslehpour

  I am new to objective c programming. I am currently trying to insert data into mysql database. I have read a couple links on this and could not find the exact answer I am looking for. Here is what I am trying to do: I have my app that user inputs a name in a text field and once the press the add button, it makes a connection to my php file and my php file does the rest of the work (using POST method) and adds the name to the mysql dataase. I have seen a lot of people use NSMutableURLRequest : setHTTPMethod :POST`` in their code (in my case my php file does that and I don't haveNSMutableURLRequest` included in my code and it works perfectly fine.) My questions are: Are there any benefits of including NSMutableURLRequest in your code when you can just call your php code to take care of the POST for you? What does NSMutableURLRequest exactly do and which way is more efficient?

• Understanding behaviour of read() and write()

  - by neo730

  hi i am a student and just start learning low level c programming.i tried to understand read() and write() methods with this program. #include <unistd.h> #include <stdlib.h> main() { char *st; st=calloc(sizeof(char),2);//allocate memory for 2 char read(0,st,2); write(1,st,2); } i was expecting that it would give segmentation fault when i would try to input more than 2 input characters.but when i execute program and enter " asdf " after giving " as " as output it executes "df" command. i want to know why it doesn't give segmentation fault when we assign more than 2 char to a string of size 2.and why is it executing rest(after 2 char)of input as command instead of giving it as output only? also reading man page of read() i found read() should give EFAULT error,but it doesn't. I am using linux.

• Language D compared to C++?

  - by Henrik

  Anyone here with experience of the language D? I was just reading through its presentation at http://www.d-programming-language.org/ and at Wikipedia and it seems like a good (better) alternative to C++. With good/better I mean that it seem simpler yet it has all the good stuff within C/C++. But without some of the difficulties that make C++ more difficult to learn and use in a good and efficient way. So anyone with comments/experience with the language D? Performance?

• Variable pre-fixes, Visual Studio 2010 onwards?

  - by thedixon

  I'm a bit bewildered on this subject, as I relate variable prefixes to being a thing of the past now, but with Visual Studio 2010 onwards (I'm currently using 2012), do people still do this and why? I only ask because, these days, you can hover over any variable and it'll tell you the variable type and scope. There's literally no requirement for pre-fixing being there for readability. By this I mean: string strHello int intHello etc. And I'm being language/tool biased here - as Visual Studio takes a lot of the legwork out for you in terms of seeing exactly what type the variable is, including after conversions in the code. This is not a "general programming" question.

• Make a simulation using python

  - by user3727759

  I am new to programming and using python. What I am trying to do is create a simulation of a thermostat system by using python. Is there a way to create a program that I can input data, for example temperature and humidity values and then have python constantly plotting the data as I enter the values. This is to simulate a device gathering data and sending it to this program and having it being plotted. I have found ways to plot data by using matplotlib but I have not been able to find a way that I can input the data and have the plot upgrade constantly. Thanks any advise is appreciated.

• Problem in the Android documentation

  - by Nick

  Hi all, This is my first post ever -- I love the Android SDK (been at it for a week), but I did notice a small typo in the official documentation that needs correcting. Not sure if this is where I post it, but on this page: http://developer.android.com/reference/android/os/CountDownTimer.html within the example source code, the source says "CountdownTimer" on line one when it should say "CountDownTimer" (notice the capitalization of the letter "D"). An easy fix for one with programming experience, but the code as written will not compile, which could be confusing for someone using this code for the first time. Is this where documentation bugs are submitted, and if not, where should I go to request the fix? Thanks all!

• Shift from Java to c++

  - by zengr

  Hello, I have been developing applications based on C# (.net) and Java (J2EE) from the last 3 years. But, now I feel, Java, C# makes you lame (from learning point of view) and you can develop your apps quickly but you fail to understand the basic underlying concepts of programming. So, I am trying to learn C++, but I find it a little "confusing" due to pointer, multiple inheritance, some conventions and other concepts of C++ which don't exist in Java. So, what do you guys suggest? How should I got about it? Thanks PS: I am a student, so have all the time in the world and actually shift.

• Simplest possible Ubuntu GUI app.

  - by Chris Becke

  On Windows, no matter which framework you use, all the frameworks need, ultimately, to call the user mode user32::CreateWindowEx API to actually create a window on the desktop. On Ubuntu, or indeed Linux systems in general, it seems that the choices are to use a widget framework like Wx or Qt or GTK+ to create a GUI application, but all these frameworks feel like they are wrapping something more fundamental. Do these all talk directly to X on Linux? I thought Ubuntu was moving to a non X window manager, so what are they going to use then? What library would I use to access the window manager all these frameworks use?

• Starting out with Objective C; need some guidance

  - by alimaxwell

  Hi Everyone, I have started learning Objective C with no prior programming experience from the 'Become an X-Coder' eBook (http://download.cocoalab.com.s3.amazonaws.com/BecomeAnXcoder.pdf). My question is, if I want to be doing iPhone development, am I going in the right direction? Am I learning the wrong language, or should I be learning Cocoa Touch? As I said, I have no prior experience, and just need someone to point me in the right direction. Apoligies if I have put this in the wrong place. Thanks very much for your time.

• Is there any way around the Chrome 5 breakage of Ajax for local files?

  - by nikow

  The recent Chrome 5.0 release completely blocks XMLHTTPRequest requests for local files comming from a local file. Here is just one of the many related bug reports and here is the code change (there is also a SO question caused by this). This breaks a lot of production code, e.g. for documentation systems. Users must be able to browse local documentation without the need to install anything or run executables. My question is if there is any way around this restriction? I'm only interested in solutions that don't require any fancy actions on the users side (nothing beyond a confirmation dialog). Is there any way the HTML5 File API could be used, or maybe postMessage()? Of course this whole issue is very frustrating for many people. Firefox takes a fare more reasonable approach and allows requests inside the directory. So it seems unlikely that other browser vendors will follow Chrome.

• increasing speed and efficiency of ajax call

  - by user1048824

  I'm not the most disciplined dev, dont know standards and am self-taught so bear with me. I create stuff very logically and fast but not always using 'programming standards'. I have a mobile app using geolocation API. it gets thousands of places from my db and makes gmaps v3 markers for the ones around the user's current location. there is an ajax call from my JS to an aspx page that calls the database, makes a json string, and sends the json string to the javascript that then creates the google map markers. would i save time if the json string was in a flat file? im not sure if, generally speaking, accessing a sql db from an aspx page is faster than c# file i/o on a flat file with pre-rendered JSON. (of course, using the flat file, it would update everytime the db is updated)

• SEO on a login based website

  - by Paul

  Ok so say I have a website that the majority of content is behind a closed door, login screen for paying customers only. How can I let google know what is there so people can find the site through a search engine. What programming techniques could I use to give more content to the google bot. I will have some overview and demonstration screens to tempt the users but will these five to ten pages of content be enough for the search engines. The key work is quite a highly sort one and there is quite alot of competition. And before anyone asks the site is not a subscription porn site (Sadly)

• int vs const int&

  - by Valdo

  I've noticed that I usually use constant references as return values or arguments. I think the reason is that it works almost the same as using non-reference in the code. But it definitely takes more space and function declarations become longer. I'm OK with such code but I think some people my find it a bad programming style. What do you think? Is it worth writing const int& over int? I think it's optimized by the compiler anyway, so maybe I'm just wasting my time coding it, a?

• Can you ask Google how common a search is?

  - by John

  I'm not familiar with Google Analytics but I think you can use it to see how many people get to your site using different search strings. But if you don't yet have the site, can you simply ask Google how popular a search is? For instance say you're choosing a new product name/slogan/etc. First of all, you want to see if that is already very crowded, which is easy through just Googling it. But now you might want to see if anyone is actually searching for this... an ideal situation would be to find a search-string lots of people are using, which doesn't put your competitors on the #1 spot. Is this possible? Not exactly programming-related, but closely related to web-development IMO... please vote to close if you disagree, I won't be offended!

• Whats wrong with my CSS?

  - by William

• Creating a CD auto-start dialog

  - by emilyshaun

  For me, compact discs and these customized auto-start dialogs are somewhat outdated and waste... However, I have to create such a dialog as an index for a CD consisting of a few PDF files. Making one to work on Microsoft Windows is quite easy. As there might be users from different platforms (Unix, Apple,...), the question raises how to offer them such a (auto-starting) dialog as well. Java is of course an option, but I think it's overloaded and naturally too slow for this purpose. Now, I think of a single webpage that will appear in the local browser. Using all these web standards this could a very creative, light-weight approach working on most systems. Do you see any problems that might occur here? Probably, there is a different and more elegant solution to this issue?

• Implementing an iterator over binary tree using C++ 11

  - by user1459339

  I would like to create an iterator over the binary tree so as to be able to use range-based for loop. I understand I ought to implement the begin() and end() function first. Begin should probably point to the root. According to the specification, however, the end() functions returns "the element following the last valid element". Which element (node) is that? Would it not be illegal to point to some "invalid" place? The other thing is the operator++. What is the best way to return "next" element in tree? I just need some advice to begin with this programming.

• iOS - How to pass information from the VIEW to the Controller?

  - by user1720503

  I am fairly new to programming in general, and have been following the CS193p videos on iTunesU. I am currently doing assignment 3, and am having trouble getting a bit of information from the View sent to the View Controller. I believe I have set up the whole delegation thing correctly, so the question really is to how to get my View Controller to see a bit of information (such as self.bounds.size.width), which is a property that only the View has. Would this involve using self.dataSource? And if so, through what means could I pass this bit of information? Thanks!!

• Tracking Useful Information

  - by Steve M

  What do the clever programmers here do to keep track of handy programming tricks and useful information they pick up over their many years of experience? Things like useful compiler arguments, IDE short-cuts, clever code snippets, etc. I sometimes find myself frustrated when looking up something that I used to know a year or two ago. My IE favourites probably represent a good chunk of the Internet in the late 1990s, so clearly that isn't effective (at least for me). Or am I just getting old? So.. what do you do?

• 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
