I sent my Bitcoin to somewhere but I’m not for sure if it was the correct address. Is there a way that I can see what address i sent it to? BTW the transaction was done on coinbaseRead more

The plot on ground ABYX, 1.416Hactares in extent is to be set out Given the following data bearing BA=YX 256′ 00′ 00” AX= 150′ 00′ 00” BY= 211′ 00′ 00” Calculate the lengths AX, XY and YB. Given that length AB is 228.60mRead more
Using python’s lxml I must read an XML file and print from each “basic” and “expert” tag, the name and email text from it. I’ve done a script that works but I don’t think is the best way of doing this. Is there a better (simpler) way for getting the data of the xml withoutRead more
I am interested in finding the distribution “$ p^*$ ” closest to an empirical distribution $ \hat{p}$ where $ p^*$ is a mixture of first and zeroth order Markov models. That is, I want to find $ $ p^* = \arg\min_p \sum_{i,j} D\left(\,\hat{p}(j|i)\, \| \, p(j|i) \,\right) $ $ subject to the following constraints $Read more
If I’m given a paclet server, “http://paclet.serv.er/” how can I determine what paclets are on it to install? E.g. how could I find all of the ServiceConnections on this server: “http://www.wolframcloud.com/objects/b3m2a1.paclets/PacletServer”?Read more
I decided to spend the last few days writing a file-finding utility in C (written for GNU/Linux) and would love to be told if this code makes my ass look fat. I want to learn the right way to write C code so that I can contribute to the opensource community (not that all opensourceRead more
Emerson and Meyer’s Paper “Dualizing the Coarse Assembly Map” (2006) states the following Proposition (5.1): Let $ X = [0,\infty)$ be the ray with its Euclidean metric coarse structure. Then the reduced K-theory of the Higson compactification $ \eta X$ of $ X$ is uncountable. The authors state that this is proved in the paperRead more
Suppose I have an even-degree polynomial $ P(x,a,b,c)$ where $ x$ is the main variable and $ a,b,c,…$ are parameters. $ P$ is also a polynomial in $ a,b,c$ . I am looking for conditions on $ a,b,c$ that makes $ P$ a square. Of course the corresponding set of equations can be written byRead more
I’m learning divide and conquer paradigm and gave a shot at a simple problem before proceeding to sorting algos. The problem is to find the sum of elements in a given array. The program works when there are more than 3 elements. As you expected, I’m talking about the base case. When I give theRead more
There is an algorithm which suggests if we start bfs from a random node(1) and reach last node t and again start bfs from t node we will get the longest path of a graph. I am trying to implement this algorithm. 1st i represent my graph through an adjacency matrix. and run bfs twice.Read more
