When I use Application Loader, I get to the point where it asks me to &quot;Choose...&quot; the file to be uploaded.

If I understand correctly, it supposes to be the appName.app file I see under &quot;Products&quot; on my app bundle (I right click it and select &quot;Show in Finder&quot; to get to the specific file in library; then I&#39;m supposed to ZIP it and the ZIP file is what I will choose in Application Loader). First, am I correct with this assumption?

if yes...

What should I define different in XCode than the way I used to build the application for testing (on simulator and on my personal iPhone)?

Should I change the **Info---&gt;Command-line build use** from **Debug** to **Release**?

How should I define the **Build Settings---&gt;Code Signing** section (in which field should I select the &quot;**iPhone Developer**&quot; option and in which should it be &quot;**iPhone Distribution**&quot;)?

Are there any other important Info/Build Settings/p.list/etc... fields I should relate to?

any help will be appreciated...

I recently had to move some code from a [PreBuildEvent in Visual Studio into the BeforeBuild target to make it work on AppHarbor][1]. While doing so, I also noticed a BeforeCompile target.

What is the difference between these three seemingly similar events: PreBuildEvent, BeforeBuild Target, BeforeCompileTarget?

What can/can&#39;t be done with each, and why would you pick one over another?

I want to run a Python script from a Python script with `subprocess`, and I wish to do it using the same interpreter for each of them.

I&#39;m using virtualenv, so I&#39;d like to do something like:

    subprocess.Popen(&#39;%s script.py&#39; % python_bin)

How do I get `python_bin`?

It should be `/usr/bin/python` outside a virtualenv, and `/path/to/env/bin/python` in a virtualenv.

I have a problem with the transfer of the variable `insurance_mode` by the decorator. I would do it by the following decorator statement:

    @execute_complete_reservation(True)
    def test_booking_gta_object(self):
        self.test_select_gta_object()

but unfortunately, this statement does not work. Perhaps maybe there is better way to solve this problem.

    def execute_complete_reservation(test_case,insurance_mode):
        def inner_function(self,*args,**kwargs):
            self.test_create_qsf_query()

I&#39;m trying to make a set of sets in Python.  I can&#39;t figure out how to do it.

Starting with the empty set `xx`:

    # Now we have some other set, for example
    elements = set([2,3,4])
    xx.add(elements)

I need to install several Python modules on a RHEL where I don&#39;t have root access. At least one of the modules also needs access to `Python.h`.

In this case I find that the best thing is to install python and it dependencies in `~/local`. It usually just works, but this time Python fails to build the SSL module (see details below). Here&#39;s the trace of what I&#39;m doing.

So I  downloaded python 6 source and off I went:

    ./configure --prefix=/home/fds/rms/local
    make &gt;&amp; make.log

An inspection to log reveals that ssl module has not been compiled, but there is no mention of the cause (no other occurence of ssl in make or configure):

    Failed to find the necessary bits to build these modules:
    _bsddb             _curses            _curses_panel
    _hashlib           _sqlite3           _ssl   &lt;----------


So I figure, python is not finding any ssl library at all (which is strange, but hey...). So I download openssl-0.9.8r and

    ./config --prefix=/home/fds/rms/local shared
    make
    make install

Now back to Python, I ./configure and make again. It fails, but this time it&#39;s different:

    Failed to build these modules:
    _hashlib           _ssl

A closer inspection to the log file reveals this:

    gcc -pthread -shared build/temp.linux-x86_64-2.6/home/fds/rms/installers/Python-2.6.6/Modules/_ssl.o -L/home/fds/rms/local/lib -L/usr/local/lib -lssl -lcrypto -o build/lib.linux-x86_64-2.6/_ssl.so
    *** WARNING: renaming &quot;_ssl&quot; since importing it failed: libssl.so.0.9.8: cannot open shared object file: No such file or directory

So now it&#39;s picking up the library but not quite getting it right (the file is there where is should be):

    $ find /home/fds/rms/local -iname libssl.so.0.9.8
    /home/fds/rms/local/lib/libssl.so.0.9.8

Next thing is tracing make and see where is it looking for the file:

    $ strace -f make 2&gt;&amp;1 | grep libssl.so.0.9.8
    [pid  5584] open(&quot;/lib/libssl.so.0.9.8&quot;, O_RDONLY) = -1 ENOENT (No such file or directory)

Mhhh, it&#39;s looking in all the wrong places. I try to give a hint:

    CPPFLAGS=&quot;-I/home/fds/rms/local/include -I/home/fds/rms/local/include/openssl&quot; LDFLAGS=&quot;-L/home/fds/rms/local/lib&quot; ./configure --prefix=/home/fds/rms/local

But nothing changes, and `make` does not seem to try `/home/fds/rms/local/lib` at all.

I haven&#39;t done this in years, so maybe I&#39;m overlooking something. Can anyone help with the problem?

Thanks in advance.

Building Python with SSL support in non-standard location

I thought I could use named parameters after variable-length positional parameters in a function call in Python 2, but I get a `SyntaxError` when importing a python class. I&#39;m writing with the following &quot;get&quot; method, for example:

    class Foo(object):
        def __init__(self):
            print &quot;You have created a Foo.&quot;

        def get(self, *args, raw=False, vars=None):
            print len(args)
            print raw
            print vars

The error looks like:

    def get(self, *args, raw=False, vars=None):
                         ^
    SyntaxError: invalid syntax


I&#39;d like to be able to call the method several ways:

    f = Foo()
    f.get(arg1, arg2)
    f.get(arg1, raw=True)
    f.get(arg1, arg2, raw=True, vars=something)

etc.

I am trying to include the path to extra libraries in my makefile, but I can&#39;t figure out how to get the compiler to use that path.  so far I have:

    g++ -g -Wall testing.cpp fileparameters.cpp main.cpp -o test

and I want to include the path to

    /data[...]/lib

because testing.cpp includes files from that library.  Also, I&#39;m on a linux machine.

EDIT: Not a path to a library.  Just to files that were included.  My bad.

Is there a way to convert this:

    /C:/Users/David/Dropbox/My%20Programs/Java/Test/bin/myJar.jar
into this?:

    C:\Users\David\Dropbox\My Programs\Java\Test\bin\myJar.jar

I am using the following code, which will return the full path of the .JAR archive, or the /bin directory.

    fullPath = new String(MainInterface.class.getProtectionDomain()
    			.getCodeSource().getLocation().getPath());

The problem is, `getLocation()` returns a `URL` and I need a normal windows filename.
I have tried adding the following after `getLocation()`:

`toString()` and `toExternalForm()` both return:
	
    file:/C:/Users/David/Dropbox/My%20Programs/Java/Test/bin/

`getPath()` returns:
	
    /C:/Users/David/Dropbox/My%20Programs/Java/Test/bin/

Note the `%20` which should be converted to space.
  
Is there a quick and easy way of doing this?

When I run Ruby commands like `gem -v` I get this error:

&gt; /Users/kristoffer/.rvm/rubies/ruby-1.9.2-p180/bin/gem:4:
&gt; warning: Insecure world writable dir
&gt; /Users/kristoffer in PATH, mode 040777 

&gt;1.6.2

First of all I don&#39;t understand what this means. /Users/kristoffer is not in my path according to `echo $PATH`. The result of `echo $PATH` is:

&gt; /Users/kristoffer/.rvm/gems/ruby-1.9.2-p180/bin:/Users/kristoffer/.rvm/gems/ruby-1.9.2-p180@global/bin:/Users/kristoffer/.rvm/rubies/ruby-1.9.2-p180/bin:/Users/kristoffer/.rvm/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

As you can see, the PATH is pretty clean. Just the default path + what RVM added. 

I&#39;ve seen the other posts similar to this where the recommended way to solve the issue is to run `chmod go-w path/to/folder`

However, I&#39;m pretty sure that it&#39;s a bad idea to make my Home folder non-writeable, right? I&#39;ve repaired permissions using Disk Utility and it didn&#39;t find anything wrong with the permissions on my Home folder.

Any idea of what the problem is and how I can fix it?

Insecure world writable dir /Users/username in PATH, mode 040777 when running Ruby commands

I am just wondering: I am looking for a way to validate if a given path is valid.
*(Note: I do not want to check if a file is existing! I only want to proof the validity of the path - So if a file could possibly exists at the location)*.

Problem is, I can&#39;t find anything in the .Net API.
Due to the many formats and locations that Windows supports, I&#39;d rather use something MS-native.

Since the function should be able to check against:

&gt; - Relative Paths (./)
&gt; - Absolute Paths (c:\tmp)
&gt; - UNC-Pathes (\\some-pc\c$)
&gt; - NTFS-Limitations like the full path 1024 chars - If I am not mistaken exceeding the path will make a file inaccessible for many
&gt; internal Windows functions. Renaming it with Explorer still works
&gt; - Volume GUID Paths : &quot;\\?\Volume{GUID}\somefile.foo

Does anyone have a function like this?

How do I go about writing a Parser (Recursive Descent?) in C#? For now I just want a simple parser that parses arithmetic expressions (and reads variables?). Though later I intend to write an xml and html parser (for learning purposes). I am doing this because of the wide range of stuff in which parsers are useful: Web development, Programming Language Interpreters, Inhouse Tools, Gaming Engines, Map and Tile Editors, etc. So what is the basic theory of writing parsers and how do I implement one in C#? Is C# the right language for parsers (I once wrote a simple arithmetic parser in C++ and it was efficient.  Will JIT compilation prove equally good?). Any helpful resources and articles. And best of all, code examples (or links to code examples). 

Note: Out of curiosity, has anyone answering this question ever implemented a parser in C#?

I have some Scala functions defined in a file, not in a class, and I would like to use them in the Scala interpreter. I know I can say `scala filename.scala` to simply run the file and exit the interpreter, but I would like to run the file and then stay in the interpreter so I can do some testing. Can anyone tell me how to simply load a file into the interpreter so I can use the functions defined within it?

How can i measure the time taken by a method and the individual statements in that method in Ruby. If you see the below method i want to measure the total time taken by the method and the time taken for database access and redis access. I do not want to write Benchmark.measure before every statement. Does the ruby interpreter gives us any hooks for doing this ?

    def foo
    # code to access database
    # code to access redis. 
    end

I created this function in Python 2.7 with `ipython`:

    def _(v):
        return v

later if I call `_(somevalue)`, I get `_ = somevalue`.

    in[3]: _(3)
    out[3]: 3
    in[4]: print _
    out[4]: 3

The function has disappeared! If I call `_(4)` I get:

```none
TypeError: &#39;int&#39; object is not callable
```

Why? What&#39;s wrong with this function?
