I can't access any cookie from JavaScript. I need to read some value and send them via JSON for my custom checks. I've tried to access cookies from JS, like it was described at: http://www.w3schools.com/js/js_cookies.asp Get cookie by name As you can see at the code, it's seen as clear as a crystal the next: var c_value = document.cookie; When I'm trying to access the document.cookie value from the Chrome's web-debugger, I see only the empty string at the Watch expressions : So I can't read cookies value, which I need. I've checked the cookie name, which I'm sending to get an associated value

I am trying to implement a dictionary (as in the physical book). I have a list of words and their meanings. What data structure / type does Java provide to store a list of words and their meanings as key/value pairs. How, given a key, can I find and return the value? You'll want a Map<String, String> . Classes that implement the Map interface include (but are not limited to): HashMap LinkedHashMap Hashtable Each is designed/optimized for certain situations (go to their respective docs for more info). HashMap is probably the most common; the go-to default. For example (using a HashMap ): Map

The ConfigParser module raises an exception if one parses a simple Java-style .properties file, whose content is key-value pairs (i..e without INI-style section headers). Is there some workaround? Alex Martelli Say you have, e.g.: $ cat my.props first: primo second: secondo third: terzo i.e. would be a .config format except that it's missing a leading section name. Then, it easy to fake the section header: import ConfigParser class FakeSecHead(object): def __init__(self, fp): self.fp = fp self.sechead = '[asection]\n' def readline(self): if self.sechead: try: return self.sechead finally: self

If I have a rdd, how do I understand the data is in key:value format? is there a way to find the same - something like type(object) tells me an object's type. I tried print type(rdd.take(1)) , but it just says <type 'list'> . Let's say I have a data like (x,1),(x,2),(y,1),(y,3) and I use groupByKey and got (x,(1,2)),(y,(1,3)) . Is there a way to define (1,2) and (1,3) as values where x and y are keys? Or does a key has to be a single value? I noted that if I use reduceByKey and sum function to get the data ((x,3),(y,4)) then it becomes much easier to define this data as a key-value pair Python
