After changing my Wordpress from http to https, the wp-admin login page failed because of too many redirections. I finally solved this problem by adding the following line to wp-config.php: $_SERVER['HTTPS'] = 'on';

准备工作： 下载Shadowsocks客户端，请参见： https://geekwagner.blogspot.com/2019/02/shadowsocks-clients-ss-for_28.html （下载ShadowsocksX-NG.app.x.x.x.zip就行，x.x.x是版本号） 注册Just My Socks账号： 点此进入 Step 1: 解压 解压下载好的ShadowsocksX-NG.app.x.x.x.zip，会得到一个名为ShadowsocksX-NG.app的应用（小飞机的图标），将它复制到你的Mac的应用程序下，便可以在launchpad中找到，方便日后使用。 Step 2: 隐私设置（ 非Mac系统不需要此步骤 ） 为顺利打开小飞机，我们需要将在“系统偏好设置”>“安全性与隐私”中，将“允许从以下位置下载的应用”设置为“任何来源”。 点击小锁头，选中“任何来源”。如果“安全性与隐私”设置中找不到“任何来源”这一项，则请进行如下设置： 1. 打开“终端”； 2. 输入命令 sudo spctl --master-disable 回车后输入你的mac密码，注意输入密码时屏幕不会有显示，输入完毕回车即可，如果没有提示错误，则说明成功。 3. 重新打开“安全性与隐私”，此时已经可以看到“任何来源”。点击小锁头，输入密码后，选择“任何来源”，然后返回。 Step 3: 打开ShadowsocksX-NG 双击小飞机，打开ShadowsocksX-NG。 便可以在右上角看到一个小飞机，说明成功安装。 Step 4: 注册Just My Socks 点此注册 进入Just My Socks官网，点击右上角“Register”或者“注册”，依照提示注册。注册完成后，在菜单栏中点击“Store”>“Browse all”，购买合适的套餐。 建议购买2.88刀每月的套餐，只要不乱看视频乱下载，肯定是足足的够用。建议月付，防止因为不可名状的原因造成太大损失。 Step 5: 获取服务器信息 登陆Just My Socks网站，点击菜单里的“Home”或者“首页”，选择右边页面中的“Your Active Products/Services”中刚刚购买的套

WordPress sites administrators often encounter a problem - zombie or fake users register to your site using fake Emails. The emails they use often strictly follow the Email format so it's hard for our program to judge if they are valid or not. Although we can prevent these users from really using our sites by sending activation Email, still they are a waste of database space and make it harder to manage members. As a result, an Email whitelist is needed to filter these annoying registrations. Geek Mail Whitelist is a plugin which can allow users with certain emails to register to your WordPress site by adding whitelist rules. What's more, it supports regular expression rules which makes it more powerful to fit all kinds of situations. And it is COMPLETELY FREE!

As the picture shows, a small square showed on every rounded div element after hover or click event in Chrome but not in Safari. To solve this strange problem, I did some search and found the solution - add the following lines to the related css code: -webkit-backface-visibility: hidden; -moz-backface-visibility: hidden;

We can use jquery-ui-bundle: npm install jquery-ui-bundle --save Then import: import 'jquery-ui-bundle'; import 'jquery-ui-bundle/jquery-ui.css';

I think most of us have one or a few old mobiles which may lie in a corner without being touched for a long time. Most of those mobiles can still work but their batteries may be dead. Some of the mobiles can be turned on without batteries but some can not especially for those smart phones. Because they will check for a valid battery before properly start up. I found an old HUAWEI PLK-AL10 from my drawer and wanted to transform it into an alarm clock. But the problem was the battery had been completely dead. I had to do some modifications to fake a batter signal to make the board believe there is a healthy battery there and rely on the micro-usb power to start up. I took the mobile apart and got the battery with which I used a multimeter to test all the pads of its connector. Here is the definition of each pad. To fake battery signal I need at least two things: 1. Add a 10K resistor between temperature sensor pad and '-' pad. Or I take apart the battery and get the protec

After flashing the local compiled image to my route, I got this error when using opkg install sometimes: * satisfy_dependencies_for: Cannot satisfy the following dependencies for iptables-mod-tproxy: * kernel (= 4.9.152-1-0b692028eb19a63deb9c9d19c9fee83c) * opkg_install_cmd: Cannot install package iptables-mod-tproxy. Here is how the OpenWRT official site says: You will get the message  “Cannot satisfy the following dependencies for…” if the kernel version installed on your device does not match the kernel version required by the package you want to install. This happens very easily when you are using a snapshot image. Try to install via opkg with option  --force-depends  (=Install/remove despite failed dependencies). Mind that this is likely to fail for kernel related packages (kmods). Make local copy of snapshot packages (not recommended, needs much space!) if you are using a snapshot image, and the snapshot packages are missing in current builds. Wait

After flashing OpenWRT to Netgear WNDR4300v1, I surprisingly found that 5GHz wireless card was missing. And I tried to flash back to OEM version but ended up in dead loop rebooting. The 5GHz wifi of WNDR4300 is provided by AR9580 which is connected by the PCI interface. I used dmesg to inspect the log of openwrt and found that PCI found nothing when starting. Was the chip broken? I nearly gave up and tried to disconnect the router with its power and went to dinner. After the dinner, I powered up the router and -- it just worked! Here is the log from dmesg.

1. Clone OpenWRT project from github git clone https://github.com/openwrt/openwrt.git 2. Find the release info from their github page. Click the 'X releases' tab can copy the commit number of the release you want. 3. Enter the folder of your cloned openwrt and reset header to that release. git reset --hard <commit number> 4. Install feeds. ./scripts/feeds update -a ./scripts/feeds install -a 5. Config. You must choose your target according to your router. make menuconfig e.g.: For router Netgear WNDR4300 * Target System => Atheros AR7xxx/AR9xxx * Subtarget  => Generic devices with nand flash * Target Profile => Netgear WNDR4300v1 * You may need LuCi Web admin interface. Please choose LuCi/Collections/luci 6. Download all packages before make make download 7. Make. (If you are in China, you may encounter some errors caused by GFW. Try to use a proxy to solve the problem.) make 8. The image will be in ./bin/targets/<your

Stateful DHCPv6  auto-configuration of IPv6 is the equivalent of DHCP in IPv4. A DHCPv6 service provides the IPv6 address to the client device and both client and server maintain the "state" of that address (i.e. lease time, etc). The router in its router advertisement message will tell the newly come-up host to ask for all address (global address, DNS address, SIP proxy server address) from the DHCPv6 server. Stateless DHCPv6  is for the auto-configuration by the client device of its IPv6 address and routing based on the router advertisements. The router tells the newly come-up host to take only the extra information like DNS, SIP proxy server address from the DHCPv6 server, while the global address is given to the host by the prefix present in the router advertisement message. The router gives the prefix of 64 bits and the host uses its MAC address (48 bits) converted in  EUI-64  method to obtain a global IPv6 address. In detail, from the article  What is the differenc
