树莓派GPIO接口只能输入输出数字信号（0&1等），传感器等模拟信号，需要通过ADC（模数转换器）进行转化。
树莓派3的GPIO管脚定义与前代有所差别了，具体的管脚参照下图：

ubuntu 17.04/Debian 10无法运行gparted，错误信息“Gtk-WARNING **: cannot open display: :0.0”,具体信息如下：

具体的解释以及解决方法如下：
If running Ubuntu 17.10/Debian 10 or newer, this issue can arise when an application has not been updated with full support for Wayland. As a workaround until the application is updated, you can run
|
1 |
$ xhost +SI:localuser:root |
which will allow the root user to display applications on your desktop.
为了保证每次启动脚本都可以自动执行，可以把上面的命令加入到.bashrc:
|
1 |
$ sed -i '$a\xhost +SI:localuser:root' ~/.bashrc |

Ubuntu 17.10上使用crosstool-ng-1.23.0建立WD MyCloud修复工具编译环境(uClibc)
参考更优雅的(不拆硬盘)拯救死翘翘了的WD MyCloud(Ubuntu 17.10)编译出来的Busybox是只有3MB大小的样子，这样编译出来的东西非常基础，功能有限。如果想要增加其他软件的时候，最少改动的情况下，一般都依赖GLIBC,而GLIBC完整编译出来的库接近50MB，而我们修复系统，是一个纯内存文件系统。直接采用GLIBC会非常浪费不多的内存空间。
因此在低内存的系统上采用uClibc，变成一个不错的选择。下面我们讲一下如何通过crosstool-ng-1.23.0构建一个我们需要的编译系统出来。
首先编译crosstool-ng-1.23.0源代码

WordPress 4.9.1无法更新翻译文件
最近更新到WordPress 4.9.1版本，结果出现了系统一直提示“翻译更新”，但是却在更新页面中找不到更新列表的问题，如下图：
WD MyCloud编译的busybox-1.23.2中增加mdadm-3.2.6
参考更优雅的(不拆硬盘)拯救死翘翘了的WD MyCloud(Ubuntu 17.10)配置编译出来的镜像中缺少mdadm，我们在此介绍一下如何增加mdadm-3.2.6的功能。

PTP简介
在通信网络中，许多业务的正常运行都要求网络时钟同步，即整个网络各设备之间的时间或频率差保持在合理的误差水平内。网络时钟同步包括以下两个概念：
时间同步：也叫相位同步（Phase synchronization），是指信号之间的频率和相位都保持一致，即信号之间的相位差恒为零。
频率同步（Frequency synchronization）：也叫时钟同步，是指信号之间在频率或相位上保持某种严格的特定关系，信号在其对应的有效瞬间以同一平均速率出现，以保证通信网络中的所有设备都以相同的速率运行，即信号之间保持恒定的相位差。
