  - by Starx

  Lets say I have a parent class class parent { } .....

• What standards and best practices should I follow to write interoperable portlets or web gadgets?

  - by Adam

  I am trying to design the standards and patterns for implementing portlets/web gadgets with the main goal of maximizing interoperability if those components were hosted in a Java app server framework or within an existing ASP.NET technology (SharePoint webparts), or a client side-only framework. Is there any guidance anywhere of the parts of different portlet standards that are shared between most portal frameworks? Is the best I can hope for is to adhere to the JSR 168 and 286 standards and hitch my wagon to Java?

• Why do so many wpf controls implement CLR properties instead of dependency properties ?

  - by msfanboy

  Hello, is it because the controls programmers are lazy, too hard to implement or not knowledgeable? Wether they are custom controls from 3rd party vendors or Microsoft itself, very much controls have often clr properties instead of DP. Result is I can not bind to them and is wpf not all about binding? :/ My next side question would be, why do so many wpf controls offer visual parts but they are not member of the visual tree ? see wpf datagrid columns, headers... What do you think?

• persistent view controller

  - by derrichh

  Im building an iphone radio application and I want to have the controls, play, pause, stop, etc. in a tool bar (a custom view controller) at the bottom of the application. I want to keep this there throughout all the views so you can control the audio while navigating through the other parts of the application (multiple view/table controllers). Is there a way to create a view that stays in place like a tab bar?

• Is INotifyPropertyChanged only for the presentation layer?

  - by D.H.

  The INotifyPropertyChanged is obviously very useful in the view model for data binding to the view. Should I also use this interface in other parts of my application (e.g. in the business layer) when I want notifications of property changes, or I am better off using other notification mechanisms? I realize that there is nothing stopping me from using it, but are there any reasons that I shouldn't?

• Easiest way to split up a large controller file

  - by timpone

  I have a rails controller file that is too large (~900 lines - api_controller). I'd like to just split it up like something like this: api_controller.rb api_controller_item_admin.rb api_controller_web.rb I don't want to split into multiple controllers. What would be the preferred way to do this? Could I just require the new parts at the end? like: require './api_controller_item_admin' require './api_controller_web'

• Camera and Image recognition

  - by kjh

  I recently watched a youtube video where a guy got a camera to recognize when a rubik's cube was held up to it, and it captured the 9 square color combination before snapping a picture of the cube and displaying the 3x3 grid on the screen of his computer. What kind of programming is this and where would I start reading to get into this sort of thing? specifically, controlling a camera, and getting it to pick out certain parts of an image and translate that data.

• buffer size for socket connection in c++

  - by wyatt

  I'm trying to build a basic POP3 mail client in C/++, but I've run into a bit of an issue. Since you have to define the buffer size when building the program, but a message can be arbitrarily large, how do you, say, get the mail server to send it to you in parts? And if this isn't the correct means of solving the problem, what is? And while I'm here, can anyone confirm for me that RFC 2822 is still the current document defining email layout? Thanks

  - by karlthorwald

  Does watir's browser.text.include? count text inside invisible divs? If so, how to search only for visible text? I put all the instructions into the html from the beginning and use jQuery to hide and unhide the relevant parts. How can I use watir's waiter to wait for only text that is visible? My problem is, that the waiter always returns true, even before I have shown a certain text.

• Writing csv header removes data from numpy array written below

  - by user338095

  I'm trying to export data to a csv file. It should contain a header (from datastack) and restacked arrays with my data (from datastack). One line in datastack has the same length as dataset. The code below works but it removes parts of the first line from datastack. Any ideas why that could be? s = ','.join(itertools.chain(dataset)) + '\n' newfile = 'export.csv' f = open(newfile,'w') f.write(s) numpy.savetxt(newfile, (numpy.transpose(datastack)), delimiter=', ') f.close()

• Making a Game Without Graphics?

  - by cam

  Is it possible or even constructive to make a game without any graphics (but is intended to become graphical) I'm not good with graphics at all, so I'd like to write the skeleton for the game then have a graphics programmer/artist fill in the rest. I could write up all the major classes, and their interactions, and all the major functions/parts of the game. If so, what should I do to make it easier to integrate graphics into the game later on (every drawn object should have a Draw, Rotate, Collide, etc method) ?

• Can one construct a "good" hash function using CRC32C as a base.

  - by DavidD

  Given that SSE 4.2 (Intel Core i7 & i5 parts) includes a CRC32 instruction, it seems reasonable to investigate whether one could build a faster general-purpose hash function. According to this only 16 bits of a CRC32 are evenly distributed. So what other transformation would one apply to overcome that? David

  How can I localize/internationalize attribute values in .NET? My specific example is for ASP.NET web parts such as WebDisplayName, WebDescription, etc. where I inherit from the base class that uses these attributes.

  In Latex, I've created a new command 'changedtext' to mark specifics parts in my document and make it appear blue: \newcommand{\changedtext}[1]{\textcolor{blue}{#1} } Is there any easy way to alter the command to have change bars appear next to the text in the resulting PDF? If not possible, any other suggestion for a visual markup (other than change bars) that would be clear on a black & white printout would be useful as well.
