nginx中文文档 官方中文文档 bookstack的中文文档 一、nginx基本概念 1. nginx是什么, 做什么事情 Nginx是一款轻量级的Web 服务器/反向代理服务器及电子邮件（IMAP/POP3）代理服务器，在BSD-like 协议下发行。其特点是占有内存少，并发能力强，事实上nginx的并发能力在同类型的网页服务器中表现较好，中国大陆使用nginx网站用户有：百度、京东、新浪、网易、腾讯、淘宝等。 以上内容摘自 百度百科 2. 反向代理 正向代理： 例如, 我们访问谷歌访问不到, 但是有一个服务器可以访问到, 那么, 我们就可以通过那个服务器访问谷歌. 对于谷歌来说, 他不知道我们是谁, 他只知道是代理服务器访问了它. 如图所示: 反向代理： 客户端对代理是无感知的, 因为客户端不需要任何配置就可以访问 注意： 正向代理需要客户端配置代理服务器, 较为常用的场景是 VPN翻墙 , 对服务器来说, 它只能感知到代理服务器的存在, 它是感知不到客户端的, 从图中就可以看出 反向代理不需要客户端配置服务器, 较为常用的场景是 负载均衡 、 防止web攻击 . 对于客户端来说, 它感知不到真实的服务器, 而是感知到了代理服务器, 可以参考图片理解 更加详细的信息可以参考大佬的博客: 博客园 Rabbit_Dale 、 知乎 3. 负载均衡 即: 当并发很高的时候,

Some time ago there was a field called targeting in the Post API Reference but now it's gone and I don't know how to add a specific location and language targeting to the post via API. I've search a lot: some results refer to the targeting parameter. I've tried it, but it seems don't working. I've tried 2 ways to achieve this, but without any success: $post_details = array('message' => $msg, 'privary' => array('value' => 'CUSTOM', 'description' => array('country' => 'Germany'))); $fb->api('/PAGE_ID/feed', 'POST', $post_details); and $post_details = array('message' => $msg, 'targeting' => array

I'm trying to set up a quick and dirty GPS lookup via LocationManager which fetches a network location (within 500 meters) every half second for ten seconds. In other words, I'm just trying to find the correct coarse Criteria settings and the correct logic to stop checking after 10 seconds of no better locations within my Handler thread. I'm thinking my main loop should look something like this: /** * Iteration step time. */ private static final int ITERATION_TIMEOUT_STEP = 500; //half-sec intervals public void run(){ boolean stop = false; counts++; if(DEBUG){ Log.d(TAG, "counts=" + counts); }

My application uses iPhone's GPS functionality, and it was working fine previously, as in it prompts user to allow the use of location services and it shows up under Settings > Location Services list. I uninstalled and re-downloaded the app from the app store, but it no longer does either of them. The app was of the same version, and hasn't been updated for a while, but the problem had started recently. The problem has been found in multiple devices (iPhone 3GS, iPhone 4, iPhone 4S) running different OS (iOS 4-5). Did Apple change how Location Services work recently? This same happend to me

I have an App with a TextView that finds your location and when you move, the value in TextView changes. I want to know what can I do in order to register the first location and then look for the location 5 min after. For example: min 0 LAT 000000 LONG 000000 ( SAVE IT ) min 5 LAT 1111111 LONG 111111 if min0 == min 5 ... To sum up, I want to compare 2 strings (lat & long at the beginning) and lat & long after 5 minutes. Any suggestion will be appreciated. This Link should serve your purpose; Go through distanceTo or distanceBetween . You can create a Location object from a latitude and
