• How to explain to a non-technical person what source code is in a few words?

  - by marcusw

  I'm writing a bit of open-source propaganda and I need to explain what source code is to a non-technical audience in ten words or less without them losing interest. I've tried things relating to recipes and the like but I'm not an English major so I'm having a really hard time with this. Any ideas?

• How to integer-divide round negative numbers *down*?

  - by Conrad Albrecht

  Seems like whenever I divide a negative int by a positive int, I need it to round down (toward -inf), not toward 0. But both C# and C++ round toward 0. So I guess I need a DivideDownward() method. I can write it in a few lines with a test for negative and so on, but my ideas seem klugey. So I'm wondering if I'm missing something and if you have an "elegant" way to round negative division downward.

• WCF hosting in .NET compact framework

  - by jauwaad

  I would like to host a service on a WinCE device. The WinCE device is the host which can be accessed(control and data acquisition) by multiple clients (PC or WinCE) over serial port, TCP, USB etc. I was considering using Protocol Buffers for serialization on the wire. It would be ideal to use WCF or remoting but as far as I see they are not implement on the Compact Framework. Anyone have any ideas how this can be achieved.

• Rails Pretty URL with Decimals

  - by Kevin Sylvestre

  I have a rails application that allows searches using longitude and latitude. I have added a 'pretty' route with: map.connect 'stores/near/:longitude/:latitude', :controller => 'stores', :action => 'index' This works for integer latitude and longitude values (http://localhost:3000/stores/near/-88/49) but fails for decimal values (http://localhost:3000/stores/near/-88.341/49.123) giving: Routing Error No route matches "/stores/near/-88/49.0" with {:method=>:get} Any ideas how to use pretty URLs in rails with decimals?

• Data-Virtualization problem with SurfaceScrollViewer

  - by TWith2Sugars

  I'm in a situation where I'm using an ItemsControl with a SurfaceScrollViewer bound to an AsyncVirtualizingCollection and all of the data is being requested. I'm aware that it's due to the ItemsControl request all of the data but I'm not sure how to get around this. I've tried the AsyncVirtualizingCollection bound to a ListBox and it works fine and I'm now attempting to having it bound to a SurfaceListBox but the problem persists. Any ideas of how to overcome this? Thanks & Regards Tony

  - by w00t

  Hi. I'm trying to do the following in a bash script: com=`ssh host "ls -lh" ` echo $com It works, but the echo will break the output (instead of getting all lines in a column, I get them all in a row). If I do: ssh host ls -lh in the CLI it will give me the correct output + layout. Any ideas?

• DataGridViewComboBoxCell inactive item painting

  - by Tired

  Hi All, We're trying to alter the DataGridViewComboBoxCell so that when the user expands the dropdown menu, inactive items are displayed in grey text. I've found out how to do this by creating a new object, which inherits from DataGridViewComboBoxEditingControl. The problem with this, is that I'm not sure how to tell the comboBoxCell, or column, to use this EditingControl, when the user clicks on the cell. Any ideas?

• Jruby rspec to be run parallely

  - by Priyank

  Hi. Is there something like Spork for Jruby too? We want to parallelize our specs to run faster and pre-load the classes while running the rake task; however we have not been able to do so. Since our project is considerable in size, specs take about 15 minutes to complete and this poses a serious challenge to quick turnaround. Any ideas are more than welcome. Cheers

• Ruby - How to remove a setter on an object

  - by Markus Orrelly

  Given a class like this: class B class << self attr_accessor :var end end Suppose I can't modify the original source code of class B. How might I go about removing the setter on the class variable var? I've tried using something like B.send("unset_method", "var="), but that doesn't work (nor does remove_method, or overwriting that method with a var= method that doesn't do anything). Any ideas?

• Determine if method is unsafe via reflection

  - by hmemcpy

  I'm looking for a way to filter out methods which have the unsafe modifier via reflection. It doesn't seem to be a method attribute. Is there a way? EDIT: it seems that this info is not in the metadata, at least I can't see it in the IL. However reflector shows the unsafe modifier in C# view. Any ideas on how it's done? Thanks!

Any ideas?

• HTML File upload field style

  - by Steven1350

  I am trying to create a file upload field that has a little bit of style to it, but I seem to be having problems finding examples of this. I know part of the reason is that the field itself varies from browser to browser. Any ideas how to do this? Or is there a way to do this without using a file element of a form that can be styled?
