    Is the threat of quantum computers over exaggerated?

    Posted: 12 Jul 2018 11:48 PM PDT

    Recently, it seems that one of the most common newly asked questions asked about a blockchain technology is whether it is quantum resistant? This is mostly asked by people without even the basic underlying understanding of cryptographic algorithms/encryptions, just another new term thrown around to create fear and uncertainty.

    As far as I know current cryptographic algos/hash etc are safe from any threats of quantum computers currently in existence and even symmetric cyphers are easy to protect against QT by just doubling the key size.

    So is this threat overblown or am i missing something?

    Working code to find 'all' shortest paths from vertex a to b in an undirected graph using Dijkstra's algorithm

    Posted: 13 Jul 2018 12:38 AM PDT

    Hello all,

    I need working code for finding all the shortest paths between vertices a and b for an undirected graph and I need to use the Dijkstra's algorithm.

    Below is the code I am using: https://gist.github.com/vcvcchaturvedi/3587fdea80e2329eef56380894e81805

    I have read that we need to take into account the relax variable and make a list of lists of paths but I am unable to convert all that into code and can't seem to visualize how I can do this. Please help.

    In my code as you can see the 'shortest_path' function gives just one path. I cannot seem to get all the paths from this function as I do not really know how I can do it. I have searched a lot on the internet with search engines for working code for same, but unable to find any.

    Thanks

    Is Computer Science anything else besides math?

    Does Computer Science / Programming consist of any other type of subject besides mathematics? If so, what all are they?
