• Should all presentational images be defined in CSS?

  - by Grant Crofton

  I've been learning (X)HTML & CSS recently, and one of the main principles is that HTML is for structure and CSS for presentation. With that in mind, it seems to me that a fair number of images on most sites are just for presentation and as such should be in the CSS (with a div or span to hold them in the HTML) - for example logos, header images, backgrounds. However, while the examples in my book put some images in CSS, they are still often in the HTML. (I'm just talking about 'presentational' images, not 'structural' ones which are a key part of the content, for example photos in a photo site). Should all such images be in CSS? Or are there technical or logical reasons to keep them in the HTML? Thanks, Grant

• Is there a centralized list of country names that can be used for web drop down boxes (and validatio

  - by Thr4wn

  There are examples online with web select boxes that have a huge list of countries and that probably will be good enough for me to use. However, by Murphy's law, there's bound to be some random country that someone is from and isn't on my list (and probably someone else also ran into this and has updated their local list). Also, when new countries are added, I won't know about it. Basically, I feel it's better practice and a better smell if there is some centralized list of country names that I can use / trust. (also it could set/follow standards for exact namings "United St..." vs "USA" etc.) I would prefer a solution that isn't IIS specific if possible

• What does :this means in Ruby on Rails?

  - by Marco

  Hi, I'm new to the Ruby and Ruby on Rails world. I've read some guides, but i've some trouble with the following syntax. I think that the usage of :condition syntax is used in Ruby to define a class attribute with some kind of accessor, like: class Sample attr_accessor :condition end that implicitly declares the getter and setter for the "condition" property. While i was looking at some Rails sample code, i found the following examples that i don't fully understand. For example: @post = Post.find(params[:id]) Why it's accessing the id attribute with this syntax, instead of: @post = Post.find(params[id]) Or, for example: @posts = Post.find(:all) Is :all a constant here? If not, what does this code really means? If yes, why the following is not used: @posts = Post.find(ALL) Thanks

• Singletons vs. Application Context in Android?

  - by mschonaker

  Recalling this post enumerating several problems of using singletons and having seen several examples of Android applications using singleton pattern, I wonder if it's a good idea to use Singletons instead of single instances shared through global application state (subclassing android.os.Application and obtaining it through context.getApplication()). What advantages/drawbacks would have both mechanisms? To be honest, I expect the same answer in this post http://stackoverflow.com/questions/2709071/singleton-pattern-with-web-application-not-a-good-idea but applied to Android. Am I correct? What's different in DalvikVM otherwise? EDIT: I would like to have opinions on several aspects involved: Synchronization Reusability Testing Thanks in advance.

• iPhone audio Filter Question

  - by Joe

  Okay, I am going to try to make this totally not a "plz send teh codez kthxbai" I am considering an app which takes sound (eventually an audio track) and applies an audio filter to it. So I can play sounds with AudioServicesPlaySystemSound via AudioToolbox framework just fine. What I need is a very simple example of how I might take a sound and apply (for instance) midrange boost etc. Actually the kind of alteration is irrelevant -- if I can get my head around how the alteration is done I can figure out the rest. I am just finding both docs and examples of altering audio in code to be very scarce. Thanks for any help!

• C++ WIN32: Short multitasking example

  - by Con Current

  I searched for examples on how to create a simple multithreaded app that does something similar to this: #include <iostream> using namespace std; int myConcurrentFunction( ) { while( 1 ) { cout << "b" << endl; } } int main( ) { // Start a new thread for myConcurrentFunction while( 1 ) { cout << "a" << endl; } } How can I get the above to output a and b "randomly" by starting a new thread instead of just calling myConcurrentFunction normally? I mean: What is the minimal code for it? Is it really only one function I have to call? What files do I need to include? I use MSVC 2010, Win32

• Suppress error with @ operator in PHP

  - by Mez

  In your opinion, is it ever valid to use the @ operator to suppress an error/warning in PHP whereas you may be handling the error? If so, in what circumstances would you use this? Code examples are welcome. Edit: Note to repliers. I'm not looking to turn error reporting off, but, for example, common practice is to use @fopen($file); and then check afterwards... but you can get rid of the @ by doing if (file_exists($file)) { fopen($file); } else { die('File not found'); } or similar. I guess the question is - is there anywhere that @ HAS to be used to supress an error, that CANNOT be handled in any other manner?

• Making a web interface for neo4j

  - by user2898839

  I have a local neo4j database server and I want to build a web interface using javascript. Ideally I want to do all the querying and display the result client side for the website. I am mostly a Java programmer and unfortunately don't have much experience with Javascript. How can I do a cypher query from the website and return the result in a format which I can display easily in a table for example? I have seen examples of doing the querying server side with servlets or node.js but really would like to just have the neo4j server and the website client. I would be interesting in seeing a small working example if it is at all possible. Thanks for your time.

• Using Linux C code and header files to compile a Windows DLL

  - by df382

  I would like to know if in general it is possible to create a C++ DLL with Visual C++ 2010 starting from C code and the header files I find in a Linux distribution. Theoretically, if I take a piece of C code (that includes different header files) from Linux and I find in the Linux file system all the header files needed for the linkage of the project, will I be able to successfully compile the project in Windows with Visual C++ 2010? Are there some examples or a tutorial for doing this? After compiling a DLL, I would like to use it in a C# application, which I will run under Linux with Mono.

• Maven overlay with war not generated by maven

  - by dnc253

  I'm pretty new to Maven, so I apologize if this is a newbie question. We are trying to integrate a 3rd-party app into ours. This 3rd-party functionality is delivered to us as a war file. As part of this integration, I want to add some extra jars and and a properties file. Googling around, I discovered overlays. However, in all the examples I've seen, it looks the the wars that are being overlayed, were themselves generated by Maven, and thus Maven can figure out dependencies, conflicts, etc. between the two. I'm just wondering if there's a way for me to overlay this 3rd-party war with this extra stuff I want. If so, what would that look like in the pom.xml?

• Using checkbox to enable eventlistener

  - by Lefty

  I have looked for a solution to this for days and days. The examples I found don't make sence to me, probably because I am both old and new (old to life and new to android/jave). I would like to add a checkbox to my preference activity that would either enable or disable receivers. This is for a service which will run in the background, at boot completed, and will depend on two things 1)is the preference true and 2) is wifi enabled. So it would work something like this; user turns on phone boot completed checks if receivers are enabled (set by checkboxpreference) if checkboxpreference is true - looks for wifi if wifi is true - registers receivers Also required would be if wifi or checkboxpreference goes "false", unregister receivers. Thanks

• Sorting issues in flexigrid with "json" data

  - by John Sieber

  I'm currently using flexigrid to display data in a current project, but am running into issues with its ability to properly sort certain columns that contain dates or numbers. The data is being sent from a ColdFusion CFC that selects the appropriate data and then delivers it in the proper "json" format. As the date/time stamps and other fields containing numbers are sent as "strings" they do not sort properly in the data grid. Is this a limitation of Flexigrid or am I sending the data improperly to Flexigrid? I can provide examples of my code if that is helpful.

• Using a JSON web service from a Java client application

  - by user383341

  I am developing a client-side Java application that has a bit of functionality that requires getting data from some web services that transmit in JSON (some RESTful, some not). No JavaScript, no web browser, just a plain JAR file that will run locally with Swing for the GUI. This is not a new or unique problem; surely there must be some open source libraries out there that will handle the JSON data transmission over HTTP. I've already found some that will parse JSON, but I'm having trouble finding any that will handle the HTTP communication to consume the JSON web service. So far I've found Apache Axis2 apparently which might have at least part of the solution, but I don't see enough documentation for it to know if it will do what I need, or how to use it. Maybe part of the problem is that I don't have experience with web services so I'm not able to know a solution when I see it. I hope some of you can point me in the right direction. Examples would be helpful.

• Resources for dashboard app backend design

  - by Nix

  I am looking for examples of code/data/infrastructure design for a dashboard-style webapp. I am designing an interface for staff and faculty at a university to access departmental resources and be alerted of cyclical processes, events, deadlines, etc. Technologies I am working with: apache tomcat 6 and a mySQL database, JSP (including JSTL), bootstrap 3, and javascript/jquery. I have basic experience most of these technologies building smaller web apps but was hoping someone could direct me towards a book or other resource that discusses how to design the db architecture (and maybe how to template) for a dashboard, esp. for something like a notification systems. Any suggestions?

• count(*) vs count(row-name) - which is more correct?

  - by bread

  Does it make a difference if you do count(*) vs count(row-name) as in these two examples? I have a tendency to always write count(*) because it seems to fit better in my mind with the notion of it being an aggregate function, if that makes sense. But I'm not sure if it's technically best as I tend to see example code written without the * more often than not. count(*): select customerid, count(*), sum(price) from items_ordered group by customerid having count(*) > 1; vs. count(row-name): SELECT customerid, count(customerid), sum(price) FROM items_ordered GROUP BY customerid HAVING count(customerid) > 1;

• [ASP.NET] Generating images: Alternate font by User Agent (OS)

  - by sinni800

  Hello, I need to generate small images for certain parts of text. Those will have to fit into the text seamlessly. I know I can not make up for every browser font settings available, but how do I have to check for Linux, Mac and Windows users depending on the user agent? I want to use the right font (of the three "Verdana, Arial, Helvetiva") for the right user agent OS. So: How do I check for the OS? What do I have to compare to in the user agent? Where can I get the other two fonts. Does the Windows-included Verdana look the same as the one used on Linux (or, is it free anyway? I don't know much about fonts)? Where do I get Helvetica? Is it Mac OS licensed? Any code examples can be in either c# or VB.NET. I can read both. Thank you in advance.

• ideas for simple objects for day to day web-dev use?

  - by Joel

  Dang-I know this is a subjective question so will probably get booted off/locked, but I'll try anyway, because I don't know where else to ask (feel free to point me to a better place to ask this!) I'm just wrapping my head around oop with PHP, but I'm still not using frameworks or anything. I'd like to create several small simple objects that I could use in my own websites to better get a feel for them. Can anyone recommend a list or a resource that could point me to say 10 day-to-day objects that people would use in basic websites? The reason I'm asking is because I'm confusing myself a bit. For example, I was thinking of a "database connection" object, but then I'm just thinking that is just a function, and not really an "object"?? So the question is: What are some examples of objects used in basic PHP websites (not including "shopping cart" type websites) Thanks!

• Excluding items from TOC in Sphinx (documenter)?

  - by Spot

  I'm using sphinx to document our internal API. For each class we're listing methods and then sub-sections under each such as Description and Examples, etc. The Table of Contents is generated automatically in the sidebar, which is great except that it lists all the sub-sections. I am looking for a way to tell Sphinx to ignore certain headings when generating the TOC. I have scoured the docs but have not found what I need. I'm sure it's something I missed. Some advice will be appreciated. Thanks.

• integrating facebook auth into my web form app

  - by user169692

  Hi, I would like to allow my users to authorise my app with their fb on registration. All of the examples i see redirect users to the fb canvas page after authorisation, but i only want this to be a step in the registration process. Essentially, i want an icon they can click that would open up a new window where they can login to fb and a simple postback to the registration page where i would detect the login and hide the login button. Any ideas on how I can achieve this using the facebook c# sdk? Thanks and Merry Christmas :)

• Random numbers from binomial distribution

  - by Sarah

  I need to generate quickly lots of random numbers from binomial distributions for dramatically different trial sizes (most, however, will be small). I was hoping not to have to code an algorithm by hand (see, e.g., this related discussion from November), because I'm a novice programmer and don't like reinventing wheels. It appears Boost does not supply a generator for binomially distributed variates, but TR1 and GSL do. Is there a good reason to choose one over the other, or is it better that I write something customized to my situation? I don't know if this makes sense, but I'll alternate between generating numbers from uniform distributions and binomial distributions throughout the program, and I'd like for them to share the same seed and to minimize overhead. I'd love some advice or examples for what I should be considering.

• How do i parse the new wow RSS feed? (LINQ to XML)

  - by Sunzaru Sven

  The link i want to parse is here. I'm looking to parse it in "real time" so that as things happen i can send myself messages/tweets and what not. I plan on having each element of the XML from the feed as an item of a class/struct. I'm really looking for LINQ to XML examples, and a good book. I've seen other LINQ to XML articles out there, but i'm just not grasping how they work. Old SQL minds are hard to break perhaps... /shrug.

• Is my way of doing threads in Android correct?

  - by Charlie

  Hi, I'm writing a live wallpaper, and I'm forking off two separate threads in my main wallpaper service. One updates, and the other draws. I was under the impression that once you call thread.start(), it took care of everything for you, but after some trial and error, it seems that if I want my update and draw threads to keep running, I have to manually keep calling their run() methods? In other words, instead of calling start() on both threads and forgetting, I have to manually set up a delayed handler event that calls thread.run() on both the update and draw threads every 16 milliseconds. Is this the correct way of having a long running thread? Also, to kill threads, I'm just setting them to be daemons, then nulling them out. Is this method ok? Most examples I see use some sort of join() / interrupt() in a while loop...I don't understand that one...
