问题 I am working on setting up an HTML5 GeoLocation script and I would like to store the zip code in a cookie but for now I am just trying to figure out how to pass the zip code variable into another function. Here is my script to reverse geo-code based on lat/long: function retrieve_zip(callback) { try { if(!google) { google = 0; } } catch(err) { google = 0; } // Stupid Exceptions if(navigator.geolocation) // FireFox/HTML5 GeoLocation { navigator.geolocation.getCurrentPosition(function(position)

nested sapply in R - breakdown

旧巷老猫 提交于 2020-04-18 05:44:18
问题 This post is related to my previous question about extracting data from nested lists, which has been answered. One of the answers contains a sapply function: usageExist <- sapply(garden$fruit, function(f){ sapply(garden$usage, '%in%', x = names(productFruit$type[[f]][["usage"]]))}) I am very new to data.table and apply functions and struggle to understand: what is happening in this particular line of code ? Why does cooking appear twice in the lists after running usageExists ? What is the

Naming issues on Oracle Packages conversion to PostgreSQL using Aws SCT tool

早过忘川 提交于 2020-04-18 05:35:13
问题 I had migrated Oracle db to Aurora postgreSQL with the help of AWS SCT tool. All packages and triggers are converted as functions in PostgreSQL. My issue here is all the names are converted with a $ (dollar) symbol. for example, A package and associated stored proc in Oracle pk_audit.sp_get_audit converted to postgreSQL as pk_audit$sp_get_audit with a $ symbol. but, In the middleware db object name is pk_audit.sp_get_audit . In order to minimise the effort on the middleware, I need to convert

Python function not supposed to change a global variable

一世执手 提交于 2020-04-15 19:22:28
问题 I am fairly new to Python and Numpy, and I encountered this issue when translating a MATLAB program into Python. As far as I can tell, the code below is behaving abnormally by modifying a global variable even though it shouldn't. import numpy as np A = np.matrix([[0, 1, 2], [3, 4, 5], [6, 7, 8]]) def function(B): B[1,1] = B[1,1] / 2 return B C = function(A) print(A) The output is: [[0 1 2] [3 2 5] [6 7 8]] The function divides the middle number of the matrix by two and returns it. But it
