How to background avoid background colour from spreading all over the page in HTML5?

background: black ;
opacity: 0.5;
font-family: Verdana;
color:#9069CA;
text-align: left;
font-size: 18px;

Downloading file before is ready

I have a button to download a file from a db and writing info on it, but the button download the file before write the info so when I open it it's empty...

I have something like this:

File f = new File("file name");
for (int i = 0; i < datos.size(); i++) {
    /*write on the file*/
}


response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition", String.format("attachment; filename=\"%s\"", f.getName()));

PHP how to check if array is a collection of specific object

In my class I have a method which expects as array, and this array should be used differently depending on the collection type. The array items should be objects, and I need to know which class instance these objects are.

For example: in the array($obj1, $obj2), I need to check the instance of these objects, which class they were created from.

I know I could iterate the array and check instanceof of each item... but is there any better way to do so?

Speech to Text in Native Language

I want to develop an app which can convert speech to text in my langauge(Tamil). What are the possible api's such as Google Voice API, Alexa (I am not sure about these! I am confused! :-( ), that can convert voice to text in that particular language.

I am ready to merge the vocabulary of the language to work in that api. The platforms can be any like android or web. Anyone suggest please!

Also give a starting point to work with that api.

Note: I want the service free for atleast in development stage. Is there any?
