内容简介:

Arduino in Action is a hands-on guide to prototyping and building DIY electronics. You’ll start with the basics—unpacking your board and using a simple program to make something happen. Then, you’ll attempt progressively more complex projects as you connect Arduino to motors, LCD displays, Wi-Fi, GPS, and Bluetooth. You’ll explore input/output sensors, including ultrasound, infrared, and light, and then use them for tasks like robotic obstacle avoidance.

Arduino programs look a lot like C or C++, so some programming skill is helpful.

网站宕机情况说明

首先对大家说声抱歉,网站于6月20日22时宕机,到6月22日1时30分恢复,总共持续了27小时30分钟。主机供应商给出的解释如下:

  1. 由于目前机器系统突然出现无法修复的错误,我们计划对这台服务器进行重装,请注意,您的数据不会受到任何影响,我们有对您的数据进行完整的备份。
  2. 由于现在无法安排到维护人员进入机房进行系统安装处理,所以暂时在今晚(20日)无法进行系统的安装,所以无法恢复正常,我们将系统的安装安排到了明天白天处理,处理后您的网站会恢复上线,服务器最晚在明天白天恢复正常运行。
  3. 此次故障修复时间过长,原因是我们最终采取的是订购了一台新的服务器进行数据转移,而不是重装之前的服务器,直接重装之前的会服务器会导致原始硬盘数据丢失(即大家的20日22点的数据),如果进行整盘备份将会更长时间,所以我们是将所有客户转移到了新的服务器,这也是导致这次故障修复时间过长的原因。

毫无疑问,这次宕机事件暴露出主机供应商太多问题。辛亏我的站点只是个人博客,稍微上点规模的网站都经不起这么长时间的故障处理。不过话说回来,恒创主机的客服响应速度快,事后也给出了额外一个月使用时间的补偿,算是厚道。考虑到我使用这大半年来主机的稳定性一直不错,我相信这只是偶然事件,并且仍然向大家推荐恒创主机。

是的,任何IDC都避免不了物理主机出现故障,如何做好容灾与备份,在最快的时间内恢复服务,才是最需要关注的问题。

另外百度网盘最近在做活动,VIP+上百G容量只需要几毛钱,大家可以去试试,我个人是百度网盘的忠实用户。
