My question is: how do I choose the verb to begin the method name? To make this question less vague, I'm often in the situation where my first choice for a method name is a noun describing the output. In these cases, I'm usually torn between appending generic

I'm using the arcpy function NumPyArraytoTable , so a NumPy structured array is the only data format that will work. Based on this thread: Writing to numpy array from dictionary and this thread: How to convert Python dictionary object to numpy array I've tried this: result = {0: 1.1181753789488595, 1: 0.5566080288678394, 2: 0.4718269778030734, 3: 0.48716683119447185, 4: 1.0, 5: 0.1395076201641266, 6: 0.20941558441558442} names = ['id','data'] formats = ['f8','f8'] dtype

I am using it as my search engine where users will type a search word, and then ZendSearch will return me an array of results ordered by relevance. However, the array that ZendSearch returns, only returns my record ID's (it doesn't return any of the actual record information). What would next be the correct way to query my Model to retrieve the results based on the ZendSearch array results which is just an array of ID's ordered based on relevance. I know of Model::find(1) which would

Is it possible to do inline or would I need two definitions? userTestStatus xxxx = { "0": { "id": 0, "name": "Available" }, "1": { "id": 1, "name": "Ready" }, "2": { "id": 2, "name": "Started" } }; I'm looking to replace the "xxx" with a definition ( I think that's the correct word ). So that later on Typescript would alert me if I used something like userTestStatus[3].nammme by mistake. 回答1: You are better off using a native array instead of an

Checking every sub-sequence is O(n^2) which is too inefficient. Any idea for improvements? 回答1: Make a new array with each element equal to the sum of the previous elements plus that one. Input: 1 4 - 3 - 4 6 - 7 8 - 5 Becomes: 1 5 2 - 2 4 - 3 5 0 ^ ^ Then look for elements that match in the resulting array. Since these represent locations where the overall change in the function is zero, you

If LinkedBlockingQueue default capacity is equal to MAX Integer, is it really helpful to use it as BlockingQueue with default capacity? 回答1: ArrayBlockingQueue is backed by an array that size will never change after creation. Setting the capacity to Integer.MAX_VALUE would create a big array with high costs in space. ArrayBlockingQueue is always bounded. LinkedBlockingQueue creates nodes dynamically until the capacity is

I've looked at Apple's example project, but without any sense of direction or explanation, I'm finding it difficult to grasp the concept of exactly how they work. I know how to use the excellent PXSourceList as a fallback, but would really like to start using view-based source lists instead if at all possible. 回答1: You tagged this with the cocoa-bindings tag, so I assume you mean "with bindings." I

Sadly I'm not very fond of the syntax (why write a and b twice?): var a, b; [a, b] = f(); Something like this would have been a lot better: var [a, b] = f(); That would still be backwards compatible. Python-like destructuring would not be backwards compatible. Anyway the best solution for JavaScript 1.5 that I have been able to come up with is: function assign(array, map) { var o = Object(); var i = 0; $.each(map, function(e, _) { o[e] = array

Here is how I do it: let array = Array(results) // la fin 回答2: If you absolutely must convert your Results to Array , keep in mind there's a performance and memory overhead, since Results is lazy. But you can do it in one line, as results.map { $0 } in swift 2.0 (or map(results)

In perl, there is an easy (and fast) way to do this: my @array = qw( 1 2 3 ); my %hash; @hash{@array} = undef; This generates a hash that looks like: { 1 => undef, 2 => undef, 3 => undef, } The best I've come up with in Ruby is: array = [1, 2, 3] hash = Hash[array.map {|x| [x, nil]}] which gives: {1=>nil, 2=>nil, 3=>nil} Is there a better Ruby way? EDIT 1 No, Array.include? is not a good idea. Its slow . It does a query in O(n) instead of O(1). My example
