修改 ServerStatus-V 探针脚本配合 vnStat 2.x 版本使用
网上常见的改版 ServerStatus 探针里采用的流量统计是根据
python函数psutil.net_io_counters()所返回的数值来显示的。所以每次系统重启就会清零，作为检测小鸡每月流量有没有跑超的实用性不大。后来发现了以 vnStat 流量统计为基础的 ServerStatus-V 项目，用比较科学的自然月流量采集方式补足了原来 ServerStatus 的短板，这也是我一直沿用的版本。最近适逢 Ubuntu 20.04 LTS 问世，我把手头上一大波的 VPS 系统更新，大致顺利。但后来发现探针监控台里越来越多小鸡的流量报告均为 0 | 0。难道是更新后比较节省流量吗？当然是不存在的。强迫症发作下无可奈何只好研究一下代码…
果然，问题就出现在这行代码里：

Installing the latest version of Aria2 in Ubuntu 18.04 LTS
Aria2 is a headless (command-line based) multi-protocol downloader. It supports the downloading of HTTP/HTTPS, FTP, SFTP, BitTorrent and Metalink resources. Many frontends exist for Aria2, they are available either as standalone apps, or browser extensions.
Technically Aria2 can function by itself, but I don’t consider its command-line functionalities to be usable for most. Thanks to its frontend-backend separation architecture, Aria2 can easily be deployed on headless servers, such as a VPS, where you can remotely push download tasks to the backend server. Since the actual download takes place on on the backend server and not your frontend device, you don’t have to worry about leaving your devices on or preventing it from entering sleep/suspend states.

Activating Google Mobile Services on a HUAWEI MediaPad M6 8.4″
My Huawei MediaPad M6 8.4″ tablet has just arrived as a replacement for the everyday tablet that I broke earlier. Shattered glass and shit. Being a super-thin bezels sucker, I find the M6’s sub-S$400 pricetag irresistible. It even has harman/kardon audio… but I was soon disappointed to find out that it doesn’t support aptX codec. In fact, the only Bluetooth codec it supports is SBC. Crap. Being a China-only model, the M6 does not come pre-installed with Google Mobile Services (GMS), which means we will need to deal with the dreaded GMS installation issue.
