• parse/collator for php

  - by dramatic

  I'm pretty much a newbie at php (at the "install an app and try to tweak it a bit" stage). Is there a tool anywhere which can take a script which is spread over many files and show you all the code which is processed (for a given set of arguments passed to the script) in a single output? For example, I want to make a call to zen cart from a script in a different language, which returns a category listing without any surrounding page. So I want to be able to trace what the actual process is to generate that then strip off all the unwanted bits to create a custom script.

• What is the advantage of using static methods in Python?

  - by Curious2learn

  I ran into unbound method error in python with the code class Sample(object): '''This class defines various methods related to the sample''' def drawSample(samplesize,List): sample=random.sample(List,samplesize) return sample Choices=range(100) print Sample.drawSample(5,Choices) After reading many helpful posts here, I figured how I could add @staticmethod above to get the code working. I am python newbie. Can someone please explain why one would want to define static methods? Or, why are not all methods defined as static methods. Thanks in advance.

• Looking to eventually build a smartphone app...

  - by Brian L

  Hi all- I'm a young, inexperienced programmer (I've had a year of Java, some MATLAB, and HTML/CSS in school) but I've decided that to get better, I'm making it my goal to produce a simple smartphone app of some kind this year- probably either webOS or Android since I'm on a PC and can't afford a Mac just to write an iPhone app. So my question is, where do I start? I've read the threads about How to Write for Android and such, but I'm not sure I have enough Java experience to just jump right in. And then there's webOS which is based on JavaScript, correct? I guess I'd just like some input from more experienced folks. I have some Barnes and Noble book credit I'm looking to get rid of too, so if there's a guide you think would be useful, feel free to request. tl;dr: Programming newbie ultimately wants to build a simple smartphone app. Where do I start?

• Integer output in Java method not same as pre-converted char value.

  - by David

  I'm trying to parse a simple text file in an integer method and then output an integer from such file so that other parts of the program can use it. For testing purposes it also displays the character value (9 in this case). The integer value for some reason is 57. I've also tried it with another part of the text file (which in that case should be 5, but is instead 53). After looking at an ASCII chart, I see that 57 is the ASCII version of the "symbol" 9 and that 53 is the ASCII version of the "symbol" 5. Is there any simple way I can fix this? I'm getting kind of frustrated as I'm a Java newbie (I've mostly only used FreePascal before this).

• Another question about ASP.NET MVC and a separate project for helper classes

  - by rockinthesixstring

  I know this topic has been discussed to death, but there is one thing that I can't wrap my head around. I'm working on a Web Application using ASP.NET MVC and I come across a scenario where I need a helper class (this usually happens in the early stages of development. So I go ahead and create a helper project in my solution that I use to manage all of my Helper Classes. Now, do I have to build that project and dump the dll in the bin directory every time I make changes to is, or is there a way to have the main web application reference the classes contained within the separate project without the separate build process? I'm just looking for the easiest way to add helper classes without the hastel of building and moving the dll every time I make a change or addition. Also, sorry for the very newbie-esque question here. All of the web apps I've build in the past have all been in the same project (web forms, App_Code, etc).

• Asp.net Site on GoDaddy Loads Slowly

  - by Randy

  I just published a very small site to GoDaddy that I programmed in Microsoft Visual Web Developer 2008. The site only contains 6 sheets, none of which are data intensive. Each has a few small images that serve mostly to navigate to the other sheets. There is no data, no SQL, nothing like that. There is one master page that governs the page layout for all of the pages. Everything works fine, for the most part. I am posting because the site loads quite slowly, particularly considering how little content is being loaded. Can anybody give me any advice about what I should look at to speed this thing up a little bit? Is this an asp.net issue? Use of master pages? Godaddy? Something else? I'm a newbie, so speak slowly. Thanks.

• Problem with displaying graphs on a Qt canvas

  - by Michal Nowotka

  Let's say I'm a Qt newbie. I want a good Qt library for displaying simple graphs. I've found the quanava library. But there is a problem. When I compiled a basic example it looks like graph edges are not painted properly when moving nodes. I don't have any idea where is a bug but this code seems to be rather simple. I think this is a problem with paint method in NodeItem class. Maybe someone has already solved this problem because this library is quite popular.

  Hi everyone, I'm a socket programming newbie. Here's a snippet: struct sockaddr_storage client_addr; ... client_addr_size = sizeof(client_addr); client_socket = accept( server_socket, (struct sockaddr *)&client_addr, &client_addr_size ); ... result = inet_ntop( AF_INET, &((struct sockaddr_in *)&client_addr)->sin_addr, client_addr_str, sizeof(client_addr_str) ); Whenever the client connects the address I get is 0.0.0.0 regardless from the host. Can anybody explain, what I'm doing wrong? Thanks.

• What are annotations and how do they actually work for frameworks like Spring?

  - by Rachel

  I am new to Spring and now a days I hear a lot about Spring Framework. I have two sets of very specific questions: Set No. 1: What are annotations in general ? How does annotations works specifically with Spring framework ? Can annotations be used outside Spring Framework or are they Framework specific ? Set No. 2: What module of Spring Framework is widely used in Industry ? I think it is Spring MVC but why it is the most used module, if am correct or correct me on this ? I am newbie to Spring and so feel free to edit this questions to make more sense.

• Basic Android Layout Question

  - by jonhobbs

  Hi, I'm new to android but I've been working my way through the tutoials. Still trying to get my head round layouts in a non-html world and was wondering how to achieve the following.... 1) I'd like to set a tiled background to fill the screen behind the whole activity 2) I'd like to place a graphic and a button underneath it centred in the middle of the screen. 3) When the user clicks the button I'd like to start a new activity and presumably I have to do something to the current activity so the user can use the back button to get back to it. Sorry for the newbie question. Jon

• Is there a smart web developer language skill combination?

  - by Cryo

  I'm no newbie to programming, but I'm making the move to a career in web development, and I've noticed that so many job postings have different combinations of skill requirements: (PHP, C#, XML, XHTML/CSS, ASP, .NET, jQuery, YUI, Joomla, Ruby, Perl, Python, Java, Javascript... the list goes on.) As of now, I've started learning XHTML, CSS, JavaScript, jQuery, PHP, and mySQL, but with so many combinations, I want to plan ahead to have a marketable combination of skills as early on as possible. Am I on the right path? What is vital for a marketable web programmer's arsenal? Thanks for your thoughts.

• Implementing simple business model in Haskell

  - by elmes

  Supose we have a very simple model: Station has at least one Train Train has at least two Stations The model has to allow to check what stations any given train visits and to check what trains visit a particular station. How to model it in Haskell? I am a Haskell newbie, so please correct me: once an object is created, you cannot modify it - you can only make a new object based on that one (~immutability). Am I right? If so, I'll have to create a lot of temporary variables with semi-initialized objects (during deserialization or even in unit tests). Basically what I need is an example of modeling domain classes in Haskell - after reading "Learn you a haskell.." I still have no idea how to use this language.

• need some jquery if-else statement help

  - by zeemy23

  Hello, the code below is broken, but I'm not sure how. I've definitely made some big assumptions here as a newbie. I'm basically trying to create an if else where imBannerRotater functions on #cast if the variable is true and #pram if it is false. How could I fix this to get that result? The # are URLs. Thanks!-zeem $(document).ready(function(){ if (mmjsRegionName == 'CO') { $("#cast").imBannerRotater({ return_type: 'json', data_map: { image_name: 'name', url_name: 'url' }, image_url: '#', base_path: '#', }); } else { $("#pram").imBannerRotater({ return_type: 'json', data_map: { image_name: 'name', url_name: 'url' }, image_url: '#', base_path: '#', }); });

• Which PHP session settings are incorrect here?

  - by Greg McNulty

  I see the savepath has no value but does it default to something? Are the other values OK? I have access to the server and PHP files but how and what do I change? The specific issue - On page 1: session_start(); $_SESSION['uType']=$row['usertype']; //save user type to session print_r($_SESSION); //Prints the user type successfully On page 2: session_start(); print_r($_SESSION); //BLANK?? Observed: Page 1 displays the session data. However, there are NO cookies created anywhere on the browser? Page 1 does a require to display page 2. Page 2 does not contain the session data. Using FireFox as the target browser (looking at cookies with web developer add-in) How do I get the session to work across all pages? Thank You and yes I am a newbie at this.

• What is the differnce between "LINQ to Entities", "LINQ to SQL" and "LINQ to Dataset".

  - by Marcel

  Hi all, I'm working for quite a while now with LINQ. However, it remained still a bit of a mystery what are the real differences between the mentioned flavours of LINQ. The successful answer will contain a short differentiation between them. What is the main goal if it, what is the benefit, and is there a performance impact... P.S. I know that there are a lot of information sources out there, but I look for a kind of a "cheat sheet" which instructs a newbie where to head to for a specific goal.

• Storm Trident 'average aggregator

  - by E Shindler

  I am a newbie to Trident and I'm looking to create an 'Average' aggregator similar to 'Sum(), but for 'Average'.The following does not work: public class Average implements CombinerAggregator<Long>.......{ public Long init(TridentTuple tuple) { (Long)tuple.getValue(0); } public Long Combine(long val1,long val2){ return val1+val2/2; } public Long zero(){ return 0L; } } It may not be exactly syntactically correct, but that's the idea. Please help if you can. Given 2 tuples with values [2,4,1] and [2,2,5] and fields 'a','b' and 'c' and doing an average on field 'b' should return '3'. I'm not entirely sure how init() and zero() work. Thank you so much for your help in advance. Eli

• Which rdfa parser for java that supports currently used rdfa attributes?

  - by lennyks

  I am building an app in Java using Jena for semantic information scraping. I am looking for a RDFa parser that would allow me to correctly extract all the rdfa statements. Specifically, one that extracts info about namespaces used and presuming that rdfa tags are correct in the page produces correct triples, ones that distinguish between object and data properties. I went through all rdfa parsers from the site http://rdfa.info/wiki/Consume for Java. They all struggle to extract any rdfa statements and if they do not crash, Jena RDFa parser shows plenty of errors and then dies a terrible death, the data is of little use as it is incorrectly processed and generally mixed up. I am newbie in this area so please be gentle:) I was also thinking of using a library written in different language but then again I don't really know how to plug it into Java code. Any suggestions?

• Calculating terrain height in 3d-space

  - by Jonas B

  Hi I'm diving into 3d programming a bit and am currently learning by writing a procedural terrain generator that generates terrain based on a heightmap. I would also want to implement some physics and my first attempt at terrain collision was by simply checking the current position vs the heightmap. This however wont work well against small objects as you'd have to calculate the height by taking the heightdifference of the nearest vertices of the object and doing this every colision check is pretty slow. Beleive me I tried googling for it but there's simply so much crap and millions of blogs posting ripped-of newbie tutorials everywhere with basically no real information on the subject, I can't find anything that explains it or even names any generally used techniques. I'm not asking for code or a complete solution, but if anyone knows a particular technique good for calculating a high-res heightmap out of the already generated and smoothed terrain I would be very happy as I could look into it further when I know what I'm looking for. Thanks

• How do I make PyScripter work? Says it cant find python26.dll

  - by Alex

  I installed PyScript to try it out but it just wont start. It only gives me the error: "Error126: Could not open Dll "python26.dll" followed by: "Python could not be properly initialized. We must quit." I think this may have something to do with the PYTHONPATH but since I'm a newbie and dont know what it is or exactly what to put in the PYTHONPATH, after some googling, I ask here. Also, when I tried to install wxPython it was impossible becouse the PYTHONPATH could not be found.(Just a side note) I have installed ActivePython 2.6 and the PATH is set so I can access python in cmd.

• How to Include SVG file as <input> background

  - by eknown

  I'm a newbie to the SVG world, just started experimenting today. I'm trying to create a mobile site where the primary graphics are all scalable, thus supporting all display resolutions. I created an svg file for my input (currently type="image"), and suprisingly the results are as expected in my code editor (Coda). In testing (mobile Safari, DT Safari and DT FF), the input displays broken image path placeholder (the oath is correct because I can right-click to download the file). How do I go about including my SVG file in the (html5) document?
