calc(1)(2)(3)() = 6, calc(1)(1)(1)(1)() = 4, calc(a)(b)(c)...(z) = a + b + c + ... + z, find the calc function. Guys, let me know your solution.
<script>
var calc = function () {
var value = (this instanceof Number ? +this : 0);
if (!arguments.length) return value;
return calc.bind(arguments[0] + value);
}
console.log(calc(1)(8)(3)(99)());
</script>

Convert an lxml.etree node tree into an object.

"""
Convert an lxml.etree node tree into an object.
Notice: Since the xml and object (json) structure is not the same,
this utils will not work correctly if there is an xml element that
contains multiple duplicate child elements. For example:
<root>
<name>Hello</name>
<name>Is it me</name>
<hello>You looking for</hello>

Steps to install a Comodo PositiveSSL certificate with Nginx.

Setting up a SSL Cert from Comodo

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.

Purchase the cert
