[Python] Tornado - send POST parameters in the body with AsyncHTTPClient

If you want to send POST data to an URL(a RESTful web service for example) with AsyncHTTPClient, you can do that :

import urllib
post_data = { 'data': 'test data' } #A dictionary of your post data
body = urllib.urlencode(post_data) #Make it into a post request
http_client = tornado.httpclient.AsyncHTTPClient()
http_client.fetch("http://127.0.0.1:8888", handle_request, method='POST', headers=None, body=body)

[Python] pip install : gcc: error: unrecognized command line option '-mno-cygwin'

If you are on Windows and get this message :

gcc: error: unrecognized command line option '-mno-cygwin'

when you type pip install greenlet (or another lib)

Then you must :
- edit or create C:\PythonXX\Lib\distutils\cygwinccompiler.py and remove any traces of -mno-cygwin

- open an new cmd and type again your pip install greenlet (or another lib)

Have fun
:o)

[iOS] viewDidLoad viewDidAppear viewWillAppear

viewWillLoad/viewDidLoad - called when the view is constructed (via the first call to retrieve the view controller's UIView via it's view property - aka lazy loading)
viewWillAppear: - when the view is being prepared to appear either immediately (animated == NO) or view a transition (animated == YES)
viewDidAppear: - if the view appearance wasn't cancelled and the view controller's view fully appears
viewWillDisappear: - complements viewWillAppear:
viewDidDisappear: - complements viewDidAppear:

viewWillUnload/viewDidUnload - deprecated APIs when the view is unload due to memory constraints (don't worry about these anymore)

[iOS 8] Detected a case where constraints ambiguously suggest a height of zero for a tableview cell's content view. We're considering the collapse unintentional and using standard height instead

If you have this message :

Warning once only: Detected a case where constraints ambiguously suggest a height of zero for a tableview cell's content view. We're considering the collapse unintentional and using standard height instead.

then just write :

- (CGFloat)tableView:(UITableView *)tableView estimatedHeightForRowAtIndexPath:(NSIndexPath *)indexPath

{

return 44;

}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath

{

return 44;

}
