For many Singaporeans, Sir Stamford Raffles was Great Leader and White Saviour all rolled into one. The one man, one country narrative allowed a simplistic telling of a complex tale concerning Singapore’s birth to take root. But Raffles was a deeply flawed man. Whether he was palming off most the heavy lifting to Farqhuar - and then publicly taking all the credit whilst privately criticising his man on the ground ...

Last week we upstreamed Milk-V Duo S SBC to Apache NuttX RTOS. (Based on Sophgo SG2000 RISC-V SoC) But NuttX Mainline changes every day. Will Milk-V Duo S suffer “Software Bit Rot”? And fail to boot NuttX someday? Let’s do Daily Automated Testing for NuttX on a Milk-V Duo S SBC, controlled by an IKEA Smart Power Plug with Home Assistant API.

DuckDB's CLI client is portable to many platforms and architectures. It handles CSV files conveniently and offers users the same rich SQL syntax everywhere. These characteristics make DuckDB an ideal tool to complement traditional Unix tools for data processing in the command line.

An RSAF report on the F-16 crash in May concluded the flight computer rejected accurate gyroscope readings, including the backup gyroscope.

When one thinks of designing an Application-specific Integrated Circuit (ASIC) chip, one would typically imagine a very high production cost, lack of access to tools and individuals can’t really do this unless you work in a company or academia. Thanks to Tiny Tapeout, these barriers are broken down and I managed to have a chip that contains my own design. I sent in a very simple project but it is still my submission no less. I went through the entire submission procedure including writing a small testbench and preparing my project for submission through the very nicely documented process from Tiny Tapeout. In this post, I will share my experience in development and demonstrating my design.

Here's how we run Rust Apps on Apache NuttX RTOS and QEMU RISC-V Emulator
