How to get one value at a time from a generator function in Python?
...but not Python 3.x
In Python >= 2.6, use next(gen). This is a built in function, and is clearer. It will also work in Python 3.

Map vs Object in JavaScript
...d Symbol keys where as Maps support more or less any key type.
If I do obj[123] = true and then Object.keys(obj) then I will get ["123"] rather than [123]. A Map would preserve the type of the key and return [123] which is great. Maps also allow you to use Objects as keys. Traditionally to do this y...

How to filter by IP address in Wireshark?
...can also limit the filter to only part of the ip address.
E.G. To filter 123.*.*.* you can use ip.addr == 123.0.0.0/8. Similar effects can be achieved with /16 and /24.
See WireShark man pages (filters) and look for Classless InterDomain Routing (CIDR) notation.
