  • Inserting a WAV at a certain point in an audio file using python

    - by Onion
    My problem is the following: I have a 2-minute long WAV file, and my aim is to insert another WAV file (7 seconds long), at a certain point in the first WAV file (say, 0:48), essentially combining the two WAVs, using python. Unfortunately I haven't been able to figure out how to do that, and was wondering if there was some obvious solution that I was missing, or if it is even feasible to do with python. Is there perhaps a library available that might provide a solution? Thanks to all in advance.

  • How to draw a single point with .Net?

    - by SoMoS
    Hello, this should be pretty simple but I don't get it. How can I draw a single point in .Net? If I use g.DrawLine(Black,0,0,0,0) nothing is drawn and if I use g.DrawLine(Black,0,0,1,0) a line with 2 dots is used. The same happens with g.DrawRectangle. This has me intrigued. Thanks in advance.

  • Measuring the limit of a point on a smooth.spline in R

    - by Subtle Array
    I'm not sure if that's the right terminology. I've entered some data into R, and I've put a smoothingSpline through it using the following command. smoothingSpline = smooth.spline(year, rate, spar=0.35) plot(x,y) lines(smoothingSpline) Now I'd like to measure some limits (or where the curve is at a given y point), and maybe to some predictive analysis on points that extend beyond the graph. Are there commands in R for doing this?

  • static wsdl for a certain end point

    - by Costa
    Hi A certain EndPoint in a web service is not likely to change a lot, also it had a problem which we worked around by putting a static wsdl to the whole web service like this <serviceMetadata httpGetEnabled="true" httpGetUrl="" externalMetadataLocation="http://IP:8250/wsdl.xml"/> Now I want the rest of end points to have a wsdl dynamically created, and one end point which require a static WSDL. I think this is impossible because there is one WSDL per WCF service.

  • Sending floating point values between processes with pipes in C

    - by Alex
    Is there a standard way of sending floating point values from a child process to a parent process in C. I have a some calculations where I want to fork a process, then have the child do some busy work, the parent do something else, and then the child send its values (which are doubles) back to the parent (presumably through a pipe). Clearly the parent could parse the stream, but I'm just wondering if there's a cleaner way?

  • Matlab - Find point of intersection between two vectors

    - by Silv3rSurf
    I have a very simple matlab question. What is the easiest way to find the point of intersection between two vectors. I am not familiar with the various matlab fuctions -- it seems like there should be one for this. For example if I have one vector from (0,0) to (6,6) and another vector from (0,6) to (6,0), I need to determine that they intersect at (3,3) Thanks.

  • Is a point inside or outside a polygon which is on the surface of a globe

    - by richard
    How do I determine if a point is inside or outside a polygon that lies on the the surface of the earth? The inside of the polygon can be determined via the right hand rule, ie. the inside of the polygon is on your right hand side when you walk around the polygon. The polygon may Circle either pole Cross the 180 longitude Cover more than 50% of the globe As the globe is a sphere the normal ray crossing algorithms do not work correctly.

  • Good starting point to learn regular expressions.

    - by Jeremy Rudd
    I'm good at learning new languages and platforms, though whenever I try to learn Reg Ex I cannot make sense of it. I once even used the Regular Expression Designer to try and put some together. What's a good starting point to understanding what looks like the only rocket-science programming language in the world? Links to articles, books or anything else that could help me get my grounding would be appreciated.

  • Preferred Access point name

    - by rantravee
    Hi, I'm hoping that someone will explain to me what preferred access point name refers to in the android system , and what is it's role . Also I'd like to know if by messing with all APN (adding a suffix to the "apn" and "type" fields to disable 3G/EDGE/GPRS connections , and the deleting this suffix ) , the preferred APN can be disrupted. Also if it need special settings in case an APN manipulation is desired.

  • Why does 99.99 / 100 = 0.9998999999999999

    - by the-locster
    Whereas 99.99 * 0.01 = 0.99 Clearly this is the age old floating point rounding issue, however the rounding error in this case seems quite large to me; what I mean is I might have expected a result of 0.99990000001 or some similar 'close' result. And for the record I got the same answer in a JavaVM and in a .Net environment.

  • Best way to send floating point numbers from .NET to Java and back

    - by Evgeny
    I'm writing a .NET application that will make an RPC call to a Java application (via a message queue). The data sent in both directions will be large arrays of floating-point numbers. What is the best way to serialize them to send them across the wire? I'd like something more compact than text, but architecture-independent as the server may not be an x86 machine. The Java application can be changed as needed.

  • Point one style class to another?

    - by user246114
    Hi, I have a css class like: .foo { background-color: red; } then I have a class specified for a list: .list1 li { background-color: tan; } is it possible to set one style class to just point to another? Something like: .list1 li { .foo; } not sure how to articulate that - I just want the .list li style to be whatever I define for the .foo class. Thanks

  • Changing git origin to point to an existing repository

    - by int3
    I'd like to make my local repo point to a different fork of the same project. Will this work? Do a merge with the 'target origin' Change the origin repo in my config file to the 'target origin' Also, if my local repo is not entirely identical to the new origin (say, I've resolved some merge conflicts in my favor), will these changes be pushed to the new origin when I do a git push, or will only commits made after the change of origin get pushed?

  • round() for float in C++

    - by Roddy
    I need a simple floating point rounding function, thus: double round(double); round(0.1) = 0 round(-0.1) = 0 round(-0.9) = -1 I can find ceil() and floor() in the math.h - but not round(). Is it present in the standard C++ library under another name, or is it missing??

  • XNA: What is the point of Unload()?

    - by Rosarch
    XNA games have an Unload() method, where content is supposed to be unloaded. But what is the point of this? If all the content is being unloaded, then the game must be exiting, in which case everything would be garbage collected anyway, right?

  • HashMap.containsValue - What's the point?

    - by Frederik
    I've got a HashMap and I need to fetch an item by its integer value. I notice there's a containsValue() function, but it would appear I still have to iterate through the map to find the correct index anyway. My question is; why use containsValue() if I'm required to traverse it afterwards? Also, am I missing the point completely? ;-)
