  • Tech necessary to build a live video chat site?

    - by tomeaton
    Hi, I'm looking to build a live video chat site. Before writing a project description, hiring a developer, etc., I'm doing a little research on what types of technologies / web development skills are necessary in order to build this type of site. The site will feature live video and audio for users to be able to chat with eachother, a simple profile which they can fill out, and the ability to filter the types of users they are connected with. Your feedback is appreciated. Thanks, Tom

  • Best way to do text processing in linux/mac ?

    - by euphoria83
    I generally need to do a fair amount of text processing for my research, such as removing the last token from all lines, extracting the first 2 tokens from each line, splitting each line into tokens, etc. What is the best way to perform this ? Should I learn Perl for this? Or should I learn some kind of shell commands? The main concern is speed. If I need to write long code for such stuff, it defeats the purpose.

  • Get notification when NSOperationQueue finishes all tasks

    - by porneL
    NSOperationQueue has waitUntilAllOperationsAreFinished, but I don't want to wait synchronously for it. I just want to hide progress indicator in UI when queue finishes. What's the best way to accomplish this? I can't send notifications from my NSOperations, because I don't know which one is going to be last, and [queue operations] might not be empty yet (or worse - repopulated) when notification is received.

  • Change TrayIcon Tooltip from ProgressMonitorDialog

    - by Raven
    Hello, i am using the Eclipse RCP trayitem, which is described in Vogellas tutorials here: http://www.vogella.de/articles/RichClientPlatform/article.html#systemtray The requirement now is not only to show the name of the app in the tooltip but also a percentage while doing lengthy operations. I understand that the trayitem attribute is a private from ApplicationWorkbenchWindowAdvisor, so I added a getter and setter method. The only thing missing is a possibility to access the trayitem instance from my ProgressMonitorDialog instance. Can you tell me, how you would solve this puzzle? Thanks

  • Performing application reliability using iis 6/7

    - by Erup
    I have web-services applications, running on Windows Server 2003. These hosts (each of them on separate appPool) contains multiple operations (consulting services). Does exist an approach to perform reliability on these hosts, in terms of appPools? If there is a way to perform it in IIS 7 - or using WCF - I would appreciate the information. Thanks

  • Django: FloatField or DecimalFied for Currency ?

    - by Hellnar
    I am curious which one would be better fitting as a currency field ? I will do simple operations such as taking difference, the percentage between old and new prices. I plan to keep two digits after the zero (ie 10.50) and majority of the time if these digits are zero, I will be hiding these numbers and display it as "10"

  • How do I move a file (or folder) from one folder to another in TortoiseSVN?

    - by codeflunky
    I would like to move a file or folder from one place to another within the same repository without having to use Repo Browser to do it, and without creating two independent add/delete operations. Using Repo Browser works fine except that your code will be hanging in a broken state until you get any supporting changes checked in afterwards (like the .csproj file for example). Update: People have suggested "move" from the command line. Is there a TortoiseSVN equivalent?

  • How can i interpret a time value in ascii into a numerical value?

    - by Bilal
    I have a file which is as follows: 15:03:21 II 0.88 0.64 15:03:31 II 0.88 0.64 15:03:42 II 0.40 0.40 etc. after loading the file in matlab, I want to be able to read the first column (which corresponds to time) and interpret them as numerical values. At the moment, they are interpreted as a string of ascii characters and i can't perform any mathematical operations on them. Does anyone have any suggestions as to how i can read the time as numbers instead of a string of ascii characters?

  • Java Best Practice for type resolution at runtime.

    - by Brian
    I'm trying to define a class (or set of classes which implement the same interface) that will behave as a loosely typed object (like JavaScript). They can hold any sort of data and operations on them depend on the underlying type. I have it working in three different ways but none seem ideal. These test versions only allow strings and integers and the only operation is add. Adding integers results in the sum of the integer values, adding strings concatenates the strings and adding an integer to a string converts the integer to a string and concatenates it with the string. The final version will have more types (Doubles, Arrays, JavaScript-like objects where new properties can be added dynamically) and more operations. Way 1: public interface DynObject1 { @Override public String toString(); public DynObject1 add(DynObject1 d); public DynObject1 addTo(DynInteger1 d); public DynObject1 addTo(DynString1 d); } public class DynInteger1 implements DynObject1 { private int value; public DynInteger1(int v) { value = v; } @Override public String toString() { return Integer.toString(value); } public DynObject1 add(DynObject1 d) { return d.addTo(this); } public DynObject1 addTo(DynInteger1 d) { return new DynInteger1(d.value + value); } public DynObject1 addTo(DynString1 d) { return new DynString1(d.toString()+Integer.toString(value)); } } ...and similar for DynString1 Way 2: public interface DynObject2 { @Override public String toString(); public DynObject2 add(DynObject2 d); } public class DynInteger2 implements DynObject2 { private int value; public DynInteger2(int v) { value = v; } @Override public String toString() { return Integer.toString(value); } public DynObject2 add(DynObject2 d) { Class c = d.getClass(); if(c==DynInteger2.class) { return new DynInteger2(value + ((DynInteger2)d).value); } else { return new DynString2(toString() + d.toString()); } } } ...and similar for DynString2 Way 3: public class DynObject3 { private enum ObjectType { Integer, String }; Object value; ObjectType type; public DynObject3(Integer v) { value = v; type = ObjectType.Integer; } public DynObject3(String v) { value = v; type = ObjectType.String; } @Override public String toString() { return value.toString(); } public DynObject3 add(DynObject3 d) { if(type==ObjectType.Integer && d.type==ObjectType.Integer) { return new DynObject3(Integer.valueOf(((Integer)value).intValue()+((Integer)value).intValue())); } else { return new DynObject3(value.toString()+d.value.toString()); } } } With the if-else logic I could use value.getClass()==Integer.class instead of storing the type but with more types I'd change this to use a switch statement and Java doesn't allow switch to use Classes. Anyway... My question is what is the best way to go about something thike this?

  • how can I get instance from the property.

    - by viky
    In my application I have a class which has properties of user-defined types like this: class MyType { public A MyProperty { get; set; } } class A { .....some methods and proeprties } for some operations that I need to perform from my main program, I create a List of MyProperty whenever creating object of MyType and pass it to my main program and there I perform different operation on these properties which reflects in there instances also. Is there any way by which I could get the object instance for any particular MyProperty from that property in the list.

  • Using a Cyc Image in Windows

    - by nrhine1
    Hi, I am trying to use a Microtheory for a research project I am working on, and am having trouble getting my saved Image of constants I create to work correctly. I save the image after creating the constants using (write-image "world\MyImage") and then going to the \server\run\ directory and using run-cyc-32bit.bat -w "world\MyImage" It loads the server correctly, but not with my constants. I found the above command at the reference page here. Thank you for any help

  • Running on Windows CE 6 'and' Windows XP

    - by Psychic
    Is it possible to create a small program that will run, without recompiling and without emulators, on both Windows CE 6 AND Windows XP SP3? From my knowledge, this isn't possible. Source code needs to be recompiled for the target platform. However, a hardware manufacturer for embedded boards is claiming otherwise. The application isn't anything complex, just a simple benchmarking tool analysing floating point operations, CPU ticks etc, and displaying the results on a plain GUI.

  • Fulltext searching array of strings

    - by Gotys
    I have a PHP array of strings: ie: "Big green car parked outside"..etc I would like to perform boolean search operations on these strings, similar to MySQL fulltext searching , or Sphinx Searching. For example, I would like to find all strings containing word "green" but not "car" Does anyone know of any existing PHP classes or libraries which would help me accomplish this ? Or can anyone suggest any google terms I could search for ? Thank you in advance!

  • For distributed applications, which to use, ASIO vs. MPI?

    - by Rhubarb
    I am a bit confused about this. If you're building a distributed application, which in some cases may perform parallel operations (although not necessarily mathematical), should you use ASIO or something like MPI? I take it MPI is a higher level than ASIO, but it's not clear where in the stack one would begin.

  • Instrumenting java core libraries

    - by Muneeb
    Hello, When we compile a java program, we get .class files. Can I access these .class files of java core libraries? e.g. can I have access to java.lang.String.class ? Actually I am doing a research and trying to find branch coverage of some java core libraries. The tool I am using for branch coverage actually instruments the .class files. Thanks

  • Projects with browsable source using dependency injection w/ guice?

    - by André
    I often read about dependency injection and I did research on google and I understand in theory what it can do and how it works, but I'd like to see an actual code base using it (Java/guice would be preferred). Can anyone point me to an open source project, where I can see, how it's really used? I think browsing the code and seeing the whole setup shows me more than the ususal snippets in the introduction articles you find around the web. Thanks in advance!

  • Which JavaScript graphics library has the best performance?

    - by DNS
    I'm doing some research for a JavaScript project where the performance of drawing simple primitives (i.e. lines) is by far the top priority. The answers to this question provide a great list of JS graphics libraries. While I realize that the choice of browser has a greater impact than the library, I'd like to know whether there are any differences between them, before choosing one. Has anyone done a performance comparison between any of these?
