• Can a Heroku app add/remove dynos or workers to/from itself?

  - by Kiwi

  Heroku allows you to add and remove dynos and workers on the fly and charges you per second that each is used. Is it possible to set up my app so that it can add/remove dynos and workers from itself depending on the load it's under? This paragraph on Heroku.com mentions an API, but I can't find out much more about it.

• Is there an OpenID demo server out there?

  - by billpg

  Hi everyone. I'm doing some experiements with adding OpenID to something I'm working on, and I'd like to test out a few providers. Is there a server out there that will go through the OpenID login process (same way that the StackOverflow group does) and tell me all the information the provider shows. I imagine it would work like... I go to example.com and type in https://www.google.com/accounts/o8/id example.com bounces me to google. I log in. Google asks me to confirm if I allow example.com access to everything. Google bounces me back to example.com example.com tells me my OpenID, email address, anything else it's got. Does such a thing please already exist?

• How to specify or add directory to Python.h search path during setup.py build/install

  - by ca2longoria

  I'm running Linux, and have downloaded a python module I must install without access to any but my particular /home/user directory (I have no root privileges nor the option to pursue them). This of course requires the Python source. This I've downloaded and have laying around in said user directory. While asking the admin to copy the proper files into /usr/include/python2.7 is the easiest way to go about this, I am hoping for a more general and portable solution to this kind of problem. Changing only data in the module source (MANIFEST.in, README.txt, setup.py, etc.), how might I add an arbitrary directory to the search path for Python.h and friends? (Without a solution, "python setup.py build" will continue returning with the "Python.h: No such file or directory" error) Thank you very much. (Additionally, is it acceptable to post this both here and on StackOverflow?)

• Disadvantages of using a swap file/partition on an SSD, even when swappiness is set to 0

  - by pjv

  What are the disadvantages of using a swap file/partition on an SSD, even when swappiness is set to 0 I'm particularly interested in the /proc/sys/vm/swappiness=0 case. How much writes are still done, in practice, to that swap file, and does it have a negative impact to the SSD or any other disadvantage? Or would it nearly compare to not having a swap file? I am pretty aware of what swappiness=0 means, just not of what it amounts to in practice. My question stems from a problem I am experiencing without a swap: http://stackoverflow.com/questions/4567972/error-executing-aapt-all-of-the-sudden. There are similar questions regarding SSD and swap but they don't go in-depth into the swappiness=0: Disadvantages of not having a swap partition, Should I keep my swap file on an SSD drive?

• Are there any StatusNet toolkits for .NET?

  - by Broam

  There are plenty of projects out there that assist developers in posting things to Twitter; the one I can think of off the top of my head is Twitterizer. Are there any projects for posting to StatusNet? Given that StatusNet implements an API very similar to Twitter, I could probably modify/extend Twitterizer to do just that. However, I'd like to avoid reinventing the wheel if at all possible if something exists already.

• Django Piston - how can I create custom methods?

  I put my questions in the code comments for clarity: from piston.handler import AnonymousBaseHandler class AnonymousAPITest(AnonymousBaseHandler): fields = ('update_subscription',) def update_subscription(self, request, months): # Do some stuff here to update a subscription based on the # number of months provided. # How the heck can I call this method? return {'msg': 'Your subscription has been updated!'} def read(self, request): return { 'msg': 'Why would I need a read() method on a fully custom API?' }

• Win32 C/C++ Load Image from memory buffer

  - by Bruno

  I want to load a image (.bmp) file on a Win32 application, but I do not want to use the standard LoadBitmap/LoadImage from Windows API: I want it to load from a buffer that is already in memory. I can easily load a bitmap directly from file and print it on the screen, but this issue is making me stuck :( What I'm looking for is a function that works like this: HBITMAP LoadBitmapFromBuffer(char* buffer, int width, int height); Thanks.

• Symfony 1.4: Storing an array in session with SetAttribute

  - by Tom

  Hi, I'm wondering if someone knows how to store an array into a user session? This is the method to store a single attribute: $this->getUser()->setAttribute('something', $something); And the documentation says: "User attributes can store any type of data (strings, arrays, and associative arrays)" ... but doesn't say anything more. The API documentation doesn't have a "SetAttributes" or something similarly obvious. Thank you.
