translate hexadecimal color code to visible color

I have a hexadecimal color code: #FF5733 but I don't know what exact color it is. Can anyone tell me what this color is? It would be the best if you can post an image to show this color!

getting select values with flask

I'm using html tag in my website but I'm not sure how to get it to submit back to flask. Do I need a submit button? Every time I try to submit I get an error "Bad Request: The browser (or proxy) sent a request that this server could not understand."

Here's my html:

<div class="two columns">
    <form name="cat" action="" method="post">
        <select name="cat">
            <option value="cats" >Categories</option>
            <option value="soon" >starting soon</option>
            <option value="football" >football</option>
            <option value="baseball" >baseball</option>
            <option value="basketball" >basketball</option>
            <option value="hockey">hockey</option>
        </select>
    </form>
</div>

and here's my function that I want to get the values from:

@app.route('/search_book', methods=['GET', 'POST'])
def search_book():

    if request.form['cat']:
        search = request.form['cat']

    print search

    return render_template('book.html')

HttpClient not reaching url

I'm writing a WP8.1 app that reads and sends data through REST API. All of them work without problems excepts the "search" one.

This API works in POST and I need to send a string in Json format defining my query. If I set only few filters, the REST API takes too long to respond. Therefore the HttpResponseMessage object has no success code and it returns a "NotFound" message, even if the web API is correcly runnning.

If I try the same request via Postman it works correctly, but if I try it via SoapUi I get a "java.net.SocketTimeoutException: Read timed out" error message.

In SoapUi I managed to extend timeout in order to get a response, but my C# code keeps on not working even if I set the TimeOut property to HttpClient object.

Can someone please help me to resolve my problem? Thanks!

When do we remove the product from website. Say, around 8 people are trying to check-out "ItemA". Many might cancel later as well. What is the general strategy that companies follow in this case?
