mapping

问题 OK first and foremost, performance is most important here so I doubt a map would work. I have a list of structs (about 16 of them) like struct A { ... }; struct B { ... }; ... each are different and each are of different sizes. I'm wondering what elegant way we might be able to do something along the lines of: char BufferA[sizeof(struct A)]; char BufferB[sizeof(struct B)]; then write some method or mapping to return BufferA if you are working with struct A. Speed is definitely the most

问题 I'm trying to get Kibana to see my location info as a geo_point. I've been running about mapping and how to do it, but I can't seem to figure it out. The data looks like this in mongodb: { "_id" : "3", "loc" : "[-122.0574, 37.41919999999999]", "fs" : "Clean", "name" : "www.googleapis.com", "timestamp" : "2016-07-02T21:02:53.623Z", "destination" : "192.168.79.136", "source" : "216.58.212.138", "vt" : "0" } How would I map the values that are stored in the key "loc" as geo_point? 回答1: In

问题 We are using Liferay 6.2 GA4, which allows you to map only few basic attributes for LDAP user import: screenName, password, emailAddress, firstName, lastName, jobTitle and group . If you want to map some custom fields you have to use custom mapping. Both cases are working fine but what we really want is to map LDAP attribute preferredLanguage to user languageId so the user language in Liferay is set based on LDAP value. What we have tried: Map preferredLanguage to languageId in standard ldap

问题 Suppose I have two files: file1 - map.txt 1, 178246 2, 289789 3, 384275 4, 869282 file2 - relation.txt 178246, 289789 384275, 178246 384275, 869282 Expected results are: 1, 2 3, 1 3, 4 But the results I got using the following code were: awk 'FNR==NR{map[$2]=$1} {$1=map[$1];$2=map[$2];print $0}' map.txt relation.txt 2, 1, 4, It was confused when I swapped the columns in map.txt like this: 178246, 1 289789, 2 384275, 3 869282, 4 relation.txt doesn't change The results became: awk 'FNR==NR{map[

问题 I have following class: public class Ad { public int Id {get;set;} public string Title { get; set; } public string UrlTitle { get; set; } public LookUp Color {get;set} public LookUp Condition {get;set} public int InsertUserId {get; set;} public DateTime InsertDate {get; set;} } LookUp class is as follows: public class LookUp { public int Id {get;set;} public string Name { get; set; } public int InsertUserId {get; set;} public DateTime InsertDate {get; set;} } Then I have ViewModels for these

问题 I'm trying to do a polar transform on the first image below and end up with the second. However my result is the third image. I have a feeling it has to do with what location I choose as my "origin" but am unsure. radius = sqrt(width**2 + height**2) nheight = int(ceil(radius)/2) nwidth = int(ceil(radius/2)) for y in range(0, height): for x in range(0, width): t = int(atan(y/x)) r = int(sqrt(x**2+y**2)/2) color = getColor(getPixel(pic, x, y)) setColor( getPixel(radial,r,t), color) 回答1: There

问题 I am working with the New York City taxi data set. The data set has columns including datetime, pickup lat/lon, dropoff lat/lon etc. Now I want to reverse geocode the lat/lon to find the borough/neighborhood. I have two data frames. 1) The first data frame contains all the points I want to classify with the name of the nearest newyork neighborhood. 2) The second data frame contains neighborhood names and their centroids. I show you a small example. df_points_to_classify: Click here to

问题 I have an OpenStreetMap server that uses TileCache to serve tiles. The tiles are generated with Mapnik. I have configured the Mapnik XML stylesheet and I can generate an image with the OSM Mapnik tool 'generate_image.py'. That image is correct and looks good. My TileCache server will serve tiles from my OSM layer; however, all I get are tiles with the background/water blue. I get no land forms, I get no street data. Can anybody help with this? TileCache Config: [osm] type=Mapnik mapfile=/var

问题 Problem: I have two overlapping 2D shapes, A and B, each shape having the same number of pixels, but differing in shape. Some portion of the shapes are overlapping, and there are some pieces of each that are not overlapping. My goal is to move all the non-overlapping pixels in shape A to the non-overlapping pixels in shape B. Since the number of pixels in each shape is the same, I should be able to find a 1-to-1 mapping of pixels. The restriction is that I want to find the mapping that

问题 I am working with Cygwin/Mintty/Vim. With <C-v> I see that <C-S-c> is encoded <83> . This mean vim can read it and I can map it using the map command. Unfortunately if I try: :inoremap <C-S-c> foobar it doesn't work... How can I make it work and why vim refuses to map Unicode keystokes? Same question for <C-S-F1> . If I execute this command: :inoremap <C-S-F1> foobar I will get something like this: [20;5~[20;5~[20;5~[20;5~[20;5~[20;5~[20;5~[20;5~[20;5~[20;5~[20;5~[20;5~[20;5~[20;5~[20;5~[20;5
