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.
I have a Post Class and a Comment Class. I have a post object and want to convert it to a Comment object. I went through Rails api and found becomes(klass).For now there is not association between a Post and Comment. So i tried
@post.becomes(Comment).
but becomes method could not be found for @post object. Am i missing something ?
I know that to filter an element with an atttribute called attrName which has value attrValue I do:
filter("[attrName='attrValue']")
but looking at the docs http://api.jquery.com/category/selectors/ I can't see an option to select all elements s.t. attrNameattrValue
Will this work
filter("[attrName>'attrValue']")
Does it make sense to always wrap an InputStream as BufferedInputStream, when I know whether the given InputStream is something other than buffered? For e.g:
InputStream is = API.getFromSomewhere()
if(!(is instanceof BufferedInputStream))
return new BufferedInputStream(is);
return is;
What is the best way for an SWT application to clean up resources before application exit? I see two options:
1) Add a DisposeListener to main window (or better, to the Display). Will it get run if an uncaught exception happens?
2) Use a shutdown hook. Any problems to be aware of there which aren't mentioned in Design of the Shutdown Hooks API?
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.
I want to write a program to recover recently deleted files on windows 7..
Is there a function in windows API that recover files? If not, how can I begin in that?
EDIT:
Or an open source project for that?
Hi All,
I'm trying to use windows' API IsTextUnicode to check if a character input is unicode or not, but is sort of buggy. I figured, it might be better using a regex. However, I'm new to constructing regular expressions. What would be the regex to check if a character is unicode or not?
Thanks...
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.
Is there a quick way to check whether a path I have is on a local disk or somewhere on the network? I can't just check to see if it's a drive letter vs. UNC, because that would incorrectly identify mapped drives as local. I assumed it would be a boolean in the DirectoryInfo object, but it appears that it's not.
I've found classic VB code to do this check (through an API), but nothing for .NET so far.
I want to use Google Chart API using javascript. (I don't want to use the python wrapper)
So how do I send data from my python code into the javascript to create graphs?
Hi. I'm using the jQuery UI Button control but don't seem to be able to adjust the size (width and height). Here's the API documentation. I tried setting a STYLE attribute on it, but then the LABEL wasn't centered correctly. Thanks.
Is there any way in .NET for a thread to determine its 'parent', i.e. the thread that created it?
I'm diagnosing a timing issue with a black box third party API and would like to find out what custom code of mine it is executing on which thread.
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?'
}

Is it possible to use the google maps API to cache the map images of a certain location so it can be loaded locally whenever the map starts up again but from a different location?
I am programming in C, using the Windows API, and would like to know how I could draw separators.
I'm a total noob when it comes to writing GUI applications, so I may need a code example.
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', $something);
And the documentation says:
"User attributes can store any type of data (strings, arrays, and associative arrays)"
... but doesn't say anything more. The API documentation doesn't have a "SetAttributes" or something similarly obvious.
Thank you.
Hi -
I'm getting JSON-encoded output from another organization's API.
In many cases, the output can be either an array of objects (if there are many) or an object (if there's just one). Right now I'm writing tortured code like this:
if ( is_array($json['candidateList']['candidate'][0]) ) {
foreach ($json['candidateList']['candidate'] as $candidate) {
// do something to each object
}
}
else {
// do something to the single object
}
How can I handle it so the "do something" part of my code only appears once and uses a standard syntax?

I need put one bitmap image to my directshow filter. Then user can use this bitmap image and do not care where is it.
First, I import this bitmap file into resource bundle, and get one IDB_BITMAP1.
Then, I need to read this IDB_BITMAP1 using opencv cvLoadImage or some windows image API to load this image into buffer.
So question is how to do this ?
Or is that possible ?
Thanks

Hello.
I'm trying to make an application that can connecto to facebook. I've found Facebook Connect for iPhone and I don't like the login form that it has.
Is there any way to make a custom login form? Is there some api functions to call to login an user on Facebook?
Thank you.
