This series of articles mainly introduces how to design and implement a Runtime based on the io-uring and Thread-per-core model.

Our final Runtime product Monoio is now open source, and you can find it at github.com/bytedance/monoio.

1. Rust Runtime Design and Implementation - General Introduction
2. Rust Runtime Design and Implementation - Design Part 1
3. Rust Runtime Design and Implementation - Design Part 2
4. Rust Runtime Design and Implementation - Component Part
5. Rust Runtime Design and Implementation - IO Compatibility Part

This article is the fourth in the series, and we have mostly covered the design aspects previously. In this part, we will focus on components such as channels.

This article is the first in the series, mainly introducing some general concepts as well as writing a very simple Runtime as an example.

UPDATE: Here is a presentation video I made(in Chinese), and the corresponding PPT. Interested viewers are welcome to watch the playback :)

I’ve recently made two attempts with eBPF and found it quite interesting, so I thought I’d share.

This article mainly summarizes common issues and thoughts in proxy framework design; it also touches on some engineering designs within the Rust + Tower ecosystem. Although there’s already plenty of discussion on this topic online, who knows, maybe after reading this article, you’ll come up with a new idea? Found out that since joining the company, I’ve been writing nothing but proxies

This article will introduce an unobtrusive method of encrypting cloud storage (using OneDrive as an example), and the code has been open sourced after the project was essentially complete.

The Raspberry Pi has already ruined three of my SD cards. Although I was able to directly contact SanDisk and Samsung customer service on two occasions, where they replaced the SD cards unconditionally adhering to the warranty terms.

However, SD (TF) cards can’t endure many write cycles. Depending on the type of flash memory cells, MLC (Multi-Level Cell) has a longer life expectancy than TLC (Triple-Level Cell) chips. Cheaper SD cards generally use TLC chips, which can only withstand a few thousand write/erase cycles. Typical Linux systems frequently delete and write a large amount of log data during use, which means that SD cards cannot be used reliably for a long period.

This time I tried to boot up the board with a damaged SD card using some unusual methods.

This article briefly summarizes current methods for accelerating internet access and details an acceleration project I developed based on Shadowsocks: go-shadowsocks-magic.

UPDATE 2019-10: Building on the ideas from this project, I extended it to support arbitrary TCP connections by decoupling the multi-connection acceleration: Rabbit TCP, which shows some improvements in stability and latency.

Let’s dig out some past work. These were some projects I worked on in July last year, and some of them might have become obsolete by now.

Last summer, I stumbled upon this device called the MiaoMiao Printer. As someone who enjoys tinkering, I got involved with reverse engineering and developing related to the MiaoMiao Printer. All the resources are available at: https://github.com/ihciah/miaomiaoji-tool

The MiaoMiao Printer is a Bluetooth thermal printer that you can connect to and print from using its app via Bluetooth. I once saw on Weibo that DIYGOD had fun with a remote print push project, which inspired me to create something similar. However, I did not fancy the idea of constantly needing to operate it manually from my phone. Considering I had a Raspberry Pi 3 handy, with Bluetooth functionality, I decided to take apart the MiaoMiao Printer’s app, extract its communication protocol, and then set up a control script on the Raspberry Pi.
