You can call [Code|Inspect Code][1] (formerly Analyze|Inspect Code, thanks to @CrackerJack9) to get all errors and warnings and ways to fix them.
In result panel you can choose to see only errors (red/yellow button at the left side).

I&#39;ve read tons of documentation related to this problem but I still can&#39;t get all the pieces together, so I&#39;d like to ask a couple of questions.

1. First of all I&#39;ll describe briefly the authentication procedure as I understand it, as I may be mistaken in that regard: A client starts a connection, which a server responds to with a combination of public key, some metadata and digital signature of a trusted authority. Then the client takes the decision if she trusts the server, encrypts some random session key with the public key and sends it back. This session key can be decrypted only with private key stored on the server. Server does this and then the HTTPS session begins.

2. So, if I&#39;m correct above, the question is how the man-in-the-middle attack can occur in such scenario? I mean, even if somebody intercepts the server (e.g. www.server.com) response with public key and has some means to make me think that he is www.server.com, he still wouldn&#39;t be able to decrypt my session key without the private key.

3. Speaking about the mutual authentication, is it all about the server confidence about the client identity? I mean, the client can already be sure that she is communicating with the right server, but now the server wants to find out who the client is, right?

4. And the last question is about the alternative to the mutual authentication. If I act as a client in the situation described, what if I send a login/password in the HTTP header after the SSL session is established? As I see it, this information can&#39;t be intercepted because the connection is already secured and the server can rely on it for my identification. Am I wrong? What are the downsides of such an approach compared with mutual authentication (only security issues are important, not the implementation complexity)?

SSL and man-in-the-middle misunderstanding

Here&#39;s the scenario: Activity contains fragment `A`, which in turn uses `getChildFragmentManager()` to add fragments `A1` and `A2` in its `onCreate` like so:

    getChildFragmentManager()
      .beginTransaction()
      .replace(R.id.fragmentOneHolder, new FragmentA1())
      .replace(R.id.fragmentTwoHolder, new FragmentA2())
      .commit()


So far, so good, everything is running as expected.

We then run the following transaction in the Activity: 

    getSupportFragmentManager()
      .beginTransaction()
      .setCustomAnimations(anim1, anim2, anim1, anim2)
      .replace(R.id.fragmentHolder, new FragmentB())
      .addToBackStack(null)
      .commit()

During the transition, the `enter` animations for fragment `B` runs correctly but **fragments A1 and A2 disappear entirely**. When we revert the transaction with the Back button, they initialize properly and display normally during the `popEnter` animation.

In my brief testing, it got weirder - if I set the animations for the child fragments (see below), the `exit` animation runs intermittently when we add fragment `B`

    getChildFragmentManager()
      .beginTransaction()
      .setCustomAnimations(enter, exit)
      .replace(R.id.fragmentOneHolder, new FragmentA1())
      .replace(R.id.fragmentTwoHolder, new FragmentA2())
      .commit()

The effect I want to achieve is simple - I want the `exit` (or should it be `popExit`?) animation on fragment `A` (anim2) to run, animating the whole container, including its nested children. 

Is there any way to achieve that?

**Edit**: Please find a test case [here][1]

**Edit2**: Thanks to @StevenByle for pushing me to keep trying with the static animations. Apparently you can set animations on a per-op basis (not global to the whole transaction), which means the children can have an indefinite static animation set, while their parent can have a different animation and the whole thing can be committed in one transaction. See the discussion below and the [updated test case project][1].

I use python 2.7 in a virtual environment and PyCharm 2.7 (new build as of feb 07 2013).

Whenever I open a python file in it that has unambiguous errors (equivalent to compile errors in other languages, e.g. using undeclared variables, calling non-existing functions), it shows red stripes in the gutter of the file.

So, I discover errors randomly as I happened to navigate to a file that contains them. What I would really like is to be able to list all of the python errors in a separate window. The Visual Studio 2005/2008/2010/... IDE has a separate &quot;Errors&quot; view that lists all of them with file names and line numbers, and gives me the ability to click on any one of these errors and navigate directly to the source.

Does PyCharm have anything like this?

I want to run a python script and capture the output on a text file as well as want to show on console.

I want to specify it as a property of the python script itself.  NOT to use the command `echo &quot;hello world&quot; | tee test.txt` on command prompt every time.

Within script I tried:

    sys.stdout = open(&#39;log.txt&#39;,&#39;w&#39;)

But this does not show the stdout output on screen.

I have heard about logging module but I could not get luck using that module to do the job.

How to redirect stdout to both file and console with scripting?

To remove frame in figure, I write 

    frameon=False

works perfect with `pyplot.figure`, but with `matplotlib.Figure` it only removes the gray background, the frame stays . Also, I only want the lines to show, and all the rest of figure be transparent.

with pyplot I can do what I want, I want to do it with matplotlib for some long reason I &#39;d rather not mention to extend my question.

I&#39;m having trouble getting data POSTed from jquery ajax.

    $(&#39;#clickme&#39;).click( function() {
    	var data = save_input(); // data
    
    	data[&#39;_sid&#39;] = $survey_id;  // survey_id injected from flask
    	data[&#39;_uip&#39;] = $user_ip; // user_ip injected from flask, request.remote_addr
    
    	$.ajax({
    		type : &quot;POST&quot;,
    		url : &quot;{{ url_for(&#39;mod.load_ajax&#39;) }}&quot;,
    		data: JSON.stringify(data),
    		contentType: &#39;application/json;charset=UTF-8&#39;,
    		success: function(result) {
    			console.log(result);
    		}
    	});
    
    	console.log(data);
    });

from the code, `data` is a javascript object like


    {
        &#39;foo&#39; : &#39;foo&#39;,
        &#39;bar&#39; : &#39;bar&#39;,
        &#39;fo_&#39; : 42,
    }

what I&#39;m trying to do in flask is :


    @mod.route(&#39;/load_ajax&#39;, methods=[&quot;GET&quot;, &quot;POST&quot;])
    def load_ajax():
        if request.method == &quot;POST&quot;:
            # load _sid and _uip from posted JSON and save other data
            # but request.form is empty.
            # &gt;&gt;&gt; request.form
            # ImmutableMultiDict([]) 
            return str(request.form)

see, the ajax request is made but no data is submitted. I do `console.log(data)` with ajax so I can see that I really have some meaningful data in `data` variable in jquery. but request.form in ajax view is empty. Where is my data submitted? 

how can I use data posted from ajax in flask?

I would like to call `foo(n)` but stop it if it runs for more than 10 seconds.  What&#39;s a good way to do this?

&gt; Design a logical expression equivalent to the following statement:
&gt; 
&gt; `x` is a list of three or five elements, the second element of which is
&gt; the string `&#39;Hip&#39;` and the first of which is not a number or Boolean.

What I have: 

    x = [&#39;Head&#39;, &#39;Hip&#39;, 10]
    print x[1] is &#39;Hip&#39;

My question: How do you check for whether or not it is a Boolean or a number?

When writing a python module and functions in it, I have some &quot;public&quot; functions that are supposed to be exposed to outsiders, but some other &quot;private&quot; functions that are only supposed to be seen and used locally and internally.

I understand in python there is no absolute private functions. But what is the best, most neat, or most used style to distinguish &quot;public&quot; functions and &quot;private&quot; functions?

I list some of the styles I know:

1. use `__all__` in module file to indicate its &quot;public&quot; functions (https://stackoverflow.com/questions/2187583/whats-the-python-all-module-level-variable-for)
2. use underscore at the beginning of name of &quot;private&quot; functions

Is there any other idea or convention that people use?

Thank you very much!

I want to wrap a test project containing C++ and OpenMP code with Cython, and build it with distutils via a `setup.py` file. The content of my file looks like this:
