utilities

I have looked everywhere to find a linux utility that will allow me to download rtmp streams. Not flv video but MP3 streams. The location of the streams I want to download are in this format. rtmp://live.site.com/loc/45/std_fc74a6b7f79c70a5f60.mp3 Anyone know of such a command line tool? Or even anything close to what I am asking for? I do not want full software applications and it would be great if it worked on Linux via Shell or something. Thanks all One of the following should do, if you have mplayer or vlc compiled with RTMP access. mplayer -dumpstream rtmp://live.site.com/loc/45/std

So I asked a question a month ago. I had a really nice answer to that question. I wanted to test if the answer works right now. But I am getting ModuleNotFoundError . I did following before testing: conda install -c conda-forge pyomo conda install -c conda-forge pyomo.extras I want to run this script in my code (copy/pasted from the other question): from pyomo.util.infeasible import log_infeasible_constraints ... SolverFactory('your_solver').solve(model) ... log_infeasible_constraints(model) Error I encounter: N:\urbs>python runme.py Traceback (most recent call last): File "runme.py", line 9,

I am learning iOS and using Apress - Beggining iOS 5 development book. The book says there is a window to preview UI elements's autosizing behaviour in size inspector as: but I can not see such a window. After searching in Xcode windows I realized that that windows actually appearing in a very short time period while switching size inspector to any other section in utilities tab. How can I make it constanly appear? Olcay Ertaş I have found the answer here Xcode 4.3 not presenting Autoresizing panel in Size Inspector Just uncheck "Use Auto Layout" option on file inspector tab: While you are

Suppose I have an array of int, float, string etc. Is there any utility API (e.g. Commons, Guava) that will give me a comma separated string? Like so, int[] a = {1,2,3,4,5}. String s = magicAPI.getCSV(a); // s == "1,2,3,4,5"; I've used OpenCSV in the past. StringWriter stringWriter = new StringWriter(); int[] a = {1,2,3,4,5}; String[] b = new String[a.length]; for ( int i = 0; i < a.length; i++) { b[i] = a[i]; } CSVWriter csvWriter = new CSVWriter(stringWriter, ","); csvWriter.writeNext(b); However, for such a trivial example you might want to just use the a StringBuilder and a for loop For

But I don't know if I should go for static methods, just a header, a class, or something else? What would be best practice? But, I don't want to have an instance of a utility class. I want to add functions like: Uint32 MapRGB (int r, int g, int b); const char* CopyString(const char* char); // etc. You know: utility methods... Don't put them in a class; just make them non-member functions at namespace scope. There's no rule that says every function has to be a member function of some class. One factor is whether to even put them in a class, or just put them as nomembers in a namespace (in Java,

Is there any method or quick way to check whether a number is an Integer (belongs to Z field) in Java? I thought of maybe subtracting it from the rounded number, but I didn't find any method that will help me with this. Where should I check? Integer Api? Quick and dirty... if (x == (int)x) { ... } edit: This is assuming x is already in some other numeric form. If you're dealing with strings, look into Integer.parseInt . One example more :) double a = 1.00 if(floor(a) == a) { // a is an integer } else { //a is not an integer. } In this example, ceil can be used and have the exact same effect.

As a “hardcore” WinForms programmer from a Win32 background I have always used Spy++ to understand what my applications are doing at the UI level including: Seeing what events the controls are sending to each other. Seeing the control tree at run time Finding the control that is drawing part of the display I then often search for the control name in the source code, very useful when you have to change the UI on a large application you don’t know well. So how do I do the same with a WPF application? (You may assume I have access to the source code of the WPF application if needed, however I
