  • persistant message queues

    - by Will
    I have several services on different machines and a message-passing system suits my problem. Reliability - sent messages always delivered, even if one end goes down - is the key concern, although it should also be fast and reasonably bandwidth-efficient. So which message queue should I use?

  • Is there a tool to generate MVC code in C#?

    - by Rity
    I was working on a project with a colleague and went out for lunch one day. Given that we only spent a few days doing design and no coding, I was surprised to find out that after lunch, he had over 40 files completed (various classes, interfaces, DTOs, etc). He told me he is just a fast typist but I need to know the real deal. He hasn't been able to sustain that kind of productivity just the initial skeletal code but still, any ideas how he did this?

  • Determining if two lines intersect

    - by Faken
    I have two lines that extend to infinity but both have a starting point. They are both described by a starting point and a vector in the direction of the line extending to infinity. I want to find out if the two lines intersect but i don't need to know where they intersect (its part of a collision detection algorithm). Everything i have looked at so far describes finding the intersection point of two lines or line segments. Anyone know a fast algorithm to solve this?

  • Collision free hash function for a specific data structure

    - by Max
    Is it possible to create collision free hash function for a data structure with specific properties. The datastructure is int[][][] It contains no duplicates The range of integers that are contained in it is defined. Let's say it's 0..1000, the maximal integer is definitely not greater than 10000. Big problem is that this hash function should also be very fast. Is there a way to create such a hash function? Maybe at run time depending on the integer range?

  • Python: Streaming Input with Subprocesses

    - by beary605
    Since input and raw_input() stop the program from running anymore, I want to use a subprocess to run this program... while True: print raw_input() and get its output. This is what I have as my reading program: import subprocess process = subprocess.Popen('python subinput.py', stdout=subprocess.PIPE, stderr=subprocess.PIPE) while True: output=process.stdout.read(12) if output=='' and process.poll()!=None: break if output!='': sys.stdout.write(output) sys.stdout.flush() When I run this, the subprocess exits almost as fast as it started. How can I fix this?

How do i make it so that even if i hover fast over them all other submenus are closed? Thanks.

  • How can I lock the cursor to the inside of a window on Mac OS X?

    - by ZorbaTHut
    I'm trying to put together a game for Mac OS X which involves a lot of fast action and flinging around of the mouse cursor. If the user wants to play in windowed mode, I'd quite like to lock the cursor to the inside of the window to avoid accidentally changing programs in the heat of battle (obviously this will cancel itself if the user changes programs or hits escape for the pause menu.) On Windows, this can be accomplished easily with ClipCursor(). I can't find an equivalent on Mac OS X. Is there one?

  • Where to put Assertions?

    - by sud03r
    Hi, Having assertions for unexpected conditions is considered to be good defensive coding practice. I happen to place assertions whenever i think something unexpected may happen, but that now seems to be an overkill to me. Additionally, sometimes mild unexpected conditions that don't necessarily lead to crash may even cause failure on customer end. Is there a hard and fast rule to put assertions? Thanks.

  • Cheap and cheerful rand() replacement.

    - by Mick
    After profiling a large game playing program, I have found that the library function rand() is consuming a considerable fraction of the total processing time. My requirements for the random number generator are not very onerous - its not important that it pass a great battery of statistical tests of pure randomness. I just want something cheap and cheerful that is very fast. Any suggestions?

  • If I never ever use HashSet, should I still implement GetHashCode?

    - by Dimitri C.
    I never need to store objects in a hash table. The reason is twofold: coming up with a good hash function is difficult and error prone. an AVL tree is almost always fast enough, and it merely requires a strict order predicate, which is much easier to implement. The Equals() operation on the other hand is a very frequently used function. Therefore I wonder whether it is necessary to implement GetHashCode (which I never need) when implementing the Equals function (which I often need)?

  • How to find which existing .NET solutions contain a certain project?

    - by Daniel Daranas
    I am exploring a structure of folders with C# projects such as the following: Projects ProjectA ProjectB ProjectC ProjectD Scattered around in the same folders as the .csproj files, there are several solution (.sln) files. Is there a fast way to find all the solutions that contain ProjectD.csproj? I can open them one by one and see what they contain, but I would like a feature such as "find all the solutions containing this project".

  • jQuery apply functionality only to class and parent elements.

    - by kylex
    I have the following list: <ul> <li class="topCurrent">One <ul> <li>One-1 <ul> <li>One-1.1 <ul> <li class="current">One-1.1.1 <ul> <li>One-1.1.1.1</li> <li>One-1.1.1.2</li> <li>One-1.1.1.3</li> </ul> </li> <li>One-1.1.2</li> </ul> </li> <li>One-1.2</li> </ul> </li> <li>One-2</li> <li>One-3</li> </ul> </li> <li>Two <ul> <li>Two-1</li> <li>Two-2</li> </ul> </li> Using the following jQuery: $("ul li ul").hide(); $("ul li").hoverIntent( function(){ $(this).children('ul').slideDown('fast'); }, function(){ $(this).children('ul').slideUp('fast'); } ); What this does is hide all of the ul below the top level ul until there is a hover over it. What I would like to do is this: If an li has a class="current" I would like that structure to be open up until the point that current is hit. It would still allow the ul below it to be displayed on a hover, as well as any other ul's, but at no point would the parents of class="current" be hidden. Suggestions? This problem has been driving me crazy. Thanks!
