file upload - Uploading Directly to S3 on CORS without Flash, from HTTPS hosted site -

-

We are looking for S3 in uploading large files (~ 100MB +)

HTML-Form includes other meta information about the file, which will be stored in our application database and not in S3. Depending on the success / failure of file-uploads on S3, the metadata about the image will be inserted in our application DB.

The application is on the Ruby-on-Rails stack and HTTPS is enabled. S3 is denied form submission, so a flash based upload is done.

  1. Direct JS uploads are not possible due to a cross-domain (CORS) limit with S3.

  2. Configuring the HTTP Server (NGNX) with the option described here (http://zefer.posterous.com/pure-html-ajax-solutions-to-upload- Files-to-s) but the application (ie, NGNX) will run behind elastic load balancer at HLTPS.

    Is there another good pattern for this requirement in the AdWords World?

    Thanks, Shriram

    CORS is now supported, then your option is 1 now

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
