// Assuming N/search is imported as `s` var mySalesOrderSearch = s.create({ type: 'salesorder' // Use the summary property of a Column to perform grouping/summarizing columns: [{ name: 'salesrep', summary: s.Summary.GROUP },{ name: 'internalid', ...

The WordPress posts table will be called wp_posts for example. By changing the table prefix you can create some security by ...

To draw a cuboid, you have to use the box() function by giving its dimensions as its parameters. size(200, 200, P3D); //Starting the P3D renderer translate(width/2, height/2); //Translating to the centre of the sketch rotateY(PI/4); //rotate so that... rotateX(PI/6); //... it will be easy to see...

Here's a program which might benefit from refactoring. It's a simple program using C++11 which is intended to calculate and print all prime numbers from 1 to 100 and is based on a program that was posted on CodeReview for review. #include <iostream> #include <vector> #include <cma...

You need to get some details from your OAuth provider of choice. We'll be looking at Google, but ASP.NET is also set up to allow out-the-box use of Twitter, Facebook and Microsoft (obviously). You'll want to go to the Google developer console (https://console.developers.google.com/) and create a pr...

When someone registers with your application, a new ApplicationUser object will be stored in the database. By default the class is very barebones, but it can be customised - you can find it in Models > IdentityModels.cs. This is mine: public class ApplicationUser : IdentityUser { public ...

Go to Providers > ApplicationOAuthProvider.cs and edit the ValidateClientRedirectUri function. This was a big gotcha to me, as if you don't do this there'll be a fantastically unhelpful error message. By default, this code will make any callbacks to your site invalid unless they're to the site's ...

I have found that the Web API template is broken - the default implementation relies on cookies in the final step, which you probably don't want to be using in a Rest API. Without a cookie, GetExternalLoginInfoAsync in RegisterExternal always returns null. I removed RegisterExternal entirely, inste...

The Shortest Common Super Sequence is a problem closely related to the longest common subsequence, which you can use as an external function for this task. The shortest common super sequence problem is a problem closely related to the longest common subsequence problem. A shortest common superseque...

public class ShortestCommonSupersequence { private static int Max(int a, int b) { return a > b ? a : b; } private static int Lcs(string x, string y, int m, int n) { var l = new int[m + 1, n + 1]; for (var i = 0; i <= m; i++) {...

In this example, we will compile functions that computes sum and difference given two real number. from __future__ import print_function import theano import theano.tensor as T #define two symbolic scalar s_x = T.fscalar() s_y = T.fscalar() #compute something s_sum = s_x + s_y s_diff = ...

The most important part of your RMD file is the YAML header. For writing an academic paper, I suggest to use PDF output, numbered sections and a table of content (toc). --- title: "Writing an academic paper in R" author: "Author" date: "Date" output: pdf_documen...

Unary operators can be defined by prepending the operator with unary_. Unary operators are limited to unary_+, unary_-, unary_! and unary_~: class Matrix(rows: Int, cols: Int, val data: Seq[Seq[Int]]){ def +(that: Matrix) = { val newData = for (r <- 0 until rows) yield for (c <...

scan is used for calling function multiple times over a list of values, the function may contain state. scan syntax (as of theano 0.9): scan( fn, sequences=None, outputs_info=None, non_sequences=None, n_steps=None, truncate_gradient=-1, go_backwards=False, m...

theano.map and theano.scan_module.reduce are wrappers of theano_scan. They can be seen as handicapped version of scan. You can view Basic scan usage section for reference. import theano import theano.tensor as T s_x = T.ivector() s_sqr, _ = theano.map( fn = lambda x:x*x, sequences = [s...
