SQLite’s BEGIN CONCURRENT enhancement allows multiple writers to process write transactions at the same time, as long as the database is in “wal” or “wal2” mode. However, COMMIT commands are still serialized. When a write transaction is initiated with “BEGIN CONCURRENT”, the database is not locked until a COMMIT is executed. This means that multiple […]
Design Thinking is a concept that has gained popularity in design circles and business networks. It has been associated with organizations like Singularity University and IDEO, and individuals at Stanford University’s design school have been pushing and selling Design Thinking. However, the deeper you dig into Design Thinking, the more vague it becomes. Despite this, […]

MultiBoy is a multiplayer gameboy that runs on WebRTC and Nitric. While I did not create the emulator used in this project, I have made some modifications to enable audio streaming. If you’re interested in trying out the demo, let me know or you can run it locally or deploy it on your AWS account. […]
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences have developed a new hydrogel ink infused with gelatin fibers that enables 3D printing of a functional heart ventricle that mimics the beating of a human heart. This breakthrough in 3D printing technology allows for the alignment of heart muscle cells in […]
How cool is this! Wavy walls, also known as crinkle crankle walls, crinkum crankum walls, serpentine walls, or ribbon walls, are gaining popularity. Not only do these walls look unique and clever, but they also use less bricks than straight walls because they can be made just one brick thin. The alternating convex and concave […]
