  • How to test my GAE site for performance

    - by Sergey Basharov
    I am building a GAE site that uses AJAX/JSON for almost all its tasks including building the UI elements, all interactions and client-server requests. What is a good way to test it for highloads so that I could have some statistics about how much resources 1000 average users per some period of time would take. I think I can create some Python functions for this purpose. What can you advise? Thanks.

  • Ubuntu quickly (python/gtk) - how to monitor stdin?

    - by neil
    I'm starting to work with Ubuntu's "quickly" framework, which is python/gtk based. I want to write a gui wrapper for a textmode C state-machine that uses stdin/stdout. I'm new to gtk. I can see that the python print command will write to the terminal window, so I assume I could redirect that to my C program's stdin. But how can I get my quickly program to monitor stdin (i.e. watch for the C program's stdout responses)? I suppose I need some sort of polling loop, but I don't know if/where that is supported within the "quickly" framework. Or is redirection not the way to go - should I be looking at something like gobject.spawn_async?

    - by quano
    Say I've got an integer, 13941412, that I wish to separate into bytes (the number is actually a color in the form 0x00bbggrr). How would you do that? In c, you'd cast the number to a BYTE and then shift the bits. How do you cast to byte in Python?

  • Pros and Cons of oursql [closed]

    - by S.Mark
    According to this python page, oursql looks very cool. oursql has real parameterization. oursql allows text or binary data to be streamed into the database and streamed out of the database, instead of requiring everything to be buffered in the client. oursql can both insert rows lazily and fetch rows lazily. oursql has unicode support on by default. So, Anyone start using it in the live projects and could share pros and cons over it?
