Is your Wireguard server not as fast as you thought? Does it suffer from constant disconnects and packet drops? Sometimes, it is simply caused by Wireguard using UDP instead of TCP. In some public networks, the ISP loves interrupting UDP traffic. With a technique called Quality of Service, they deliberately slow down UDP traffic to avoid network congestion in busy hours.
The Raspberry Pi 4 is the fastest of all Pi. It brings new interfaces to the Pi family: The USB 3.0 port, and gigabit ethernet. Now, people won’t have to be constrained by the crappy USB 2.0 interface of the previous Raspberry Pi generations. The Raspberry Pi Compute Module 4 is even better.
Those nasty little dot files… When I tried to setup a Gitlab continuous deployment, I encountered a tiny problem: How to remove all files within a Linux directory? Apparently it is quite easy. Just with a simple rm -rf dir/* Wrong! The above command rm -r dir/* only remove all visible files and directories from the directory dir.
Installing new Arch Linux machines are always delightful. Customization, lightweight, and maximum performance. However, in my career of installing 5 Arch Linux servers, there is this one server that always seems fishy. When zsh-autosuggestions tries to suggest past commands, the terminal’s cursor always gets messed up and starts to glitch everywhere.
Wireguard sure is nice. It is both easy to use and has quite good network performance. It is almost unambiguously better than its predecessor, OpenVPN. Moreover, Wireguard is already deployed everywhere (yes, Cloudflare Warp is pure Wireguard). So, what’s the problem? If Wireguard is so good, just use a Wireguard VPN everywhere, and you can forget about leaking your IP addresses or being DDoSed.
