How to convert a map location (lat, lng) pair to a screen position (x, y) pair in mapbox

问题 I am using mapbox javascript API to do some cool stuff on a map. Now I have a map location (latitude, longitude) pair and I want to set the view to this location then use javascript to simulate a click at this location. The problem is that I need to find out the screen position (x, y) pair of this location after setting the view. But how do I do that? It seems there is an API L.ICRS. I tried but it returned NaN for both x and y -- please check my example javascript codes below. var latlng =

问题 I'm looking to create an app in android that basically tracks a phones location and periodically adds a marker to the google maps api so that a route can be displayed, the problem I have is that I don't know how to get the location periodically and in the background.

nginx基础配置篇

序言 nginx是非常流行的一个http反向代理服务器，虽然不是专业的运营人员，但作为开发人员，掌握一些基本的用法也是蛮必要的，本篇记录nginx的一些基本配置。 调整工作进程数 nginx启动会创建主进程和工作进程，默认只会创建一个工作进程用于处理连接（底层使用epoll等事件处理模型），如果是多核服务器，建议把工作进程的数量设置为cpu的核数，如8核cpu可以如下设置： worker_processes 8; 基本资源访问 1) 最常见的nginx用法就是把它当作一个静态资源服务器，先看一个最简单的例子： 在本机hosts文件中如下配置： 127.0.0.1 static.test.com nginx.conf配置server: server { listen static.test.com; root D:/learn/static; } 然后访问 http://static.test.com/hello.js 即可以访问到 D:/learn/static/hello.js。 2) 我们也可以配置多个域名同时访问同一个资源 在hosts中添加如下映射：127.0.0.1 static2.test.com nginx.conf配置server: server { listen 80; server_name static.test.com static2.test.com;
