• DWMEnableBlurBehind makes my interface controls semi transparent

  - by user146780

  I have enabled blur on my window. I have some edit fields and some custom controls and I would not want these to be affected by the blur, they are semi transparent as a result. How could I only blur the main window itself, not its child controls (sort of like Chrome). Thanks

  I would like to plot some image binary data on a grayscale matrix-like graph with custom values on axes. I'm using Perl on a Windows machine but I can't fine the right module to do this. I'm already using GD::Graph to plot other type of data but it seems unsuitable for this specific task.

  I'm using custom post types in WordPress 3.0 to manage 'courses' (or seminars, lectures, whatever term you'd prefer to have in mind). Now for viewing a single 'course', the url structure is; /course/course-name/ But for multiple courses? /courses/category/category-name/ Or... /course-category/category-name/ Or something entirely different?

• How do i create multiple URLs with /controller/action/ format?

  - by Angela

  I have several controller/actions where no :id needs to be passed. what I did with the first two was make a custom route defining the controller and action. I thought that the default would allow me to create controller/action.xml by using respond_to in the controller, but that doesn't appear to be the right way. How can I create controller/action URL's (some are .xml) without creating a special route with map.connect?

• Why is there no circle or ellipse primitive in openGL?

  - by Ram Bhat

  Hey guys. Circles are one of the basics geometric entities. Yet there is no primitives defined in openGl for this like lines or polygons. Why so? Its a little annoying to include custom headers for this all the time! Any specific reason to omit it?

• Send files between python+django and C#

  - by SuitUp

  Hi, i would like to know, what is the best way to send files between python and C# and vice versa. I have my own protocol which work on socket level, and i can send string and numbers in both ways. Loops works too. With this i can send pretty much anything, like package of users id, if it is simple data. But soon i will start sending whole files, maybe xml or executables. Simple server with files is no an option because i want sending files from client too. I was thinking about serialization but i don't know it is the best solution, but if it is i will love some tips from stackoverflow community. EDIT: I added django to question and chose using http.

• What do I need to know before working on an IM application?

  - by John

  I'm looking into building an IM-type application using Java stack (for the server at least). I'd be interested to see any information/advice on how applications like Skype/AIM/MSN work, as well as know any technologies/APIs that might be relevant. Without giving away the idea itself, it's perhaps more akin to Google Wave than Skype, but information useful for either is very welcome. Specific points I have already thought of include: Server Vs P2P... for reasons of logging my system will require all communication to go through a central server. Is this how other IM tools work... especially when audio/video comes into the equation? Cross-communication with other systems. Are there APIs for this or do all IM providers work hard to keep their protocol secret? The nature of what I'm designing means integration could probably only be limited, but it definitely seems worthwhile from a business perspective

  For a long time I used Courier New as default font for my code editor, until I got more into typography and found this new fixed-width font called Triskweline: The font is beautiful, but unfortunately it works only at size 10pt.

• drupal views block arguments

  - by slimcady

  I currently have a view (Drupal 6 using Views2) that properly aggregates a custom content type (videos) and filters them for a page display. When I create a block display, it previews the results in live preview just great, but when i go to the page expecting to see the block it doesn't appear. I'm fairly certain the argument I'm attempting to pass it fails because when I select "Display all results" for "Action to take if argument does not validate:" the block shows up on the page just fine. Any advice definitely appreciated.

• How to get at TCP RTT on Windows (Linux TCP_INFO) as an user

  - by FredAlkin

  I am porting a streaming TCP app from Linux to Windows. The app streams real-time audio data using a preexisting TCP protocol (so switching to UDP isn't an option). Further, I wish to avoid being "part of the problem" and requiring Administrator rights. The Linux code uses getsockopt(... ,SOL_TCP, TCP_INFO, ..) to get the RTT (round trip time) information from the TCP connection. The application level uses this to throttle the amount of data sent over the connection (apparently to balance quality with latency). Is there an equivalent to TCP_INFO on WIndows? (google tells me that Win2K and later supports "TCP Timestamps" which would provide this information, but I've yet to find a way to get at it. Thanks in advance.

• What is the most efficient way to pass data (list of pairs of [Integer + Double]) between two Google App Engine instances?

  - by ruslan

  What is the most efficient way to pass data (list of pairs of [Integer, Double]) between two Google App Engine instances ? Currently I use Java binary serialization. Frontend servlet receives data from the client in JSON format. I convert it to byte[] using ObjectOutput.writeObject and then send it to backend servlet via HTTP POST. It's not in production yet. Should I just pass client's JSON as it is to backend? It seems more logical. But it's bigger in size. Or should I use Google Protocol Buffers as stated in this benchmark article ? Thank you!!!

• How to setup a http(s) proxy with record/replay functionality?

  - by superb

  The use case is: I want to do some android app performance tests and I want to fix the data when app got from web. The solution I come up with is to setup a local http proxy, which can first record all http traffic, and later replay then app is running perf tests. I found http://mitmproxy.org/, which has exactly the features I want. but seems with the default settings it cannot be used as a https proxy. I tried using it as proxy and login to facebook but doesn't work. I am not familiar with the https protocol and how cert things work. Any one can provide some help? Thanks a lot.
