A Better Duino Coin Miner

If you just want the miner (and see the world burn), click here. When talking about mining cryptocurrency, most people will first think about large mining farms with thousands of machines with powerful GPUs, or even ASICs. It is strikingly similar to the “fields” in the Matrix series. I mean, just search for images of mining farms. They are one of the few things in 21st century that looks straight out of a science fiction....

When not to Pi: Projects you shouldn't give to your Raspberry Pi

For a long time, I have pictured Raspberry Pi as the perfect computer. It’s cheap, its price is low, the manufacturing costs are minimal. To me, the most significant advantage of a Pi to a conventional computer is: “I won’t feel any remorse after accidentally breaking a Raspberry Pi or ripping it apart.” So why aren’t Raspberry Pis used everywhere? Turns out Pis are known to the State of California to cause [REDACTED], if consumed....

Improve Battery Life on Linux Laptop to the Extreme

Recently I got a new laptop. It is an ASUS Zenbook flip model with i7-1165G7 (4 core…). I thought about getting an AMD model, but if there is anything good about Intel these days, it is their Linux support for mobile CPU. Right after I got this laptop, I did the thing any conscious human would do: Putting Arch Linux on it. The bundled Windows 10 is anything but user-friendly. Upon first boot, the laptop immediately exploded....

Hiding Wireguard over TCP with udp2raw

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. As much as I hate it, they are probably doing the right thing....

3 Ways to Speed up Raspberry Pi's File Transfer

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. A whole PCIe 2.0 port? That’s like 5Gbps of transfer speed! That is enough to enjoy the lightning speed of NVMe SSDs....
