Debug, debug, debug… Somehow it all worked!

In my freshman year at Berkeley, I did a lot of projects for Electrical Engineering and Computer Science courses. I think those projects taught me way more than doing problem sets or preparing for exams, and they became a place to preserve my hacker spirit under intense academic pressures.

I like to think about doing projects as a combination of rigorous thinking, purposefully trying, and having a flow of creativity.

Maybe you think about it as to be formal and be scrappy. I think the picture below really captures the idea (you might…


Realizing, Re-learning, Optimizing | life and reflection of an EECS freshman

Well, well, well, it is uni time. Finally, I get to live in PST, not EST anymore, which made orientation week so sleep-deprived. However, the semester flew by so fast like a dream that I barely realize I got spring semester coming up tomorrow. I decided, for the first time, I need to sit down and look back on what really happened last fall.

In a Nutshell

So I started my journey as an engineering student at Berkeley, studying Electrical Engineering and Computer Sciences (EECS).

👨‍💻 Learned functional programming and lisp-like languages…


Published the day before the first Neuralink announcement

As a neurotech enthusiast, I can’t fall asleep after I saw Neuralink’s tweet recently. Tomorrow, they are finally going to reveal their secretive research — something that might make one of the biggest leaps in human cognition.

Being actively involved in neurotech projects and built a Brain-Computer Interface product (Muse 2, one of the most advanced consumer BCIs) before, I want to share some thoughts based on my understanding of the field. …


Small fun projects that I made with my peers

Besides numerous weekend-long hackathon projects, I have worked on a few fun projects that take about an hour or less. All of them are created at my high school, Upper Canada College, with my schoolmates and teachers. I have witnessed tremendous progress in the maker resources at the school, from using the first 3D-printer to the first dedicated maker space. I enjoy taking a break to express my creativity, mentoring younger schoolmates, and learning new techniques.


I want to try doing something different on birthday starting this year.

After a 3-day 5-AP marathon, here comes my birthday. While I don’t usually celebrate my birthday a lot — to be honest, it is just that day every year that you get lots of messages and several gifts — I want to take this particular day to reflect on the past year and set goals for the next 365 days.

My 16th year on earth has been quite challenging and quite rewarding. There were lots of first times, first time travelling alone, first time starting a business, first…


I was fortunate to get a ticket to attend the Consumer Electronics Show 2018 in Las Vegas as a 16-year-old. After two days of tireless walking and watching countless booths and demos, I was Whoa-ed by the innovations and concepts. Despite the rainy weather on the first day (which ruined Google’s booth) and the power outage on the second day, the show successfully showed the latest technological innovation and the trend in the consumer electronics sector. …

The Craziest Summer Trip Ever

I am Simon, and I am a die heart hardware lover. I grew up in Shanghai and started playing with electronics since very young. I have never gone to Shenzhen in my life. Being away from China for two years, I heard about some crazy hardware innovation going on there. I also found out TechCrunch was hosting a conference in Shenzhen in the summer. I immediately signed up and start planning my one-week trip there in Summer 2017. …

What were the motivations and objectives of the Marshall Plan?
By Simon Zirui Guo | CHA3U | May 2nd, 2017

The European Recovery Program (ERP), or known as the Marshall Plan, a program that the U.S. invested approximately $13 billion in rebuilding Western Europe’s economy over four years, undoubtedly played a significant role in shaping the post-WWII Europe. The plan was issued at a controversial period, when the European continent was left with severe destruction and poverty, and a rising ideology war between U.S. and U.S.S.R.. “Our policy is directed not against any country or doctrine but against hunger, poverty…

The Avro Arrow (CF-105) was a interceptor designed by Avro Canada. It was designed as a flying weapon system, to intercept high speed bombers invading North America, under the demands of NATO , NORAD, and the RCAF. However, it was cancelled by Diefenbaker’s Conservative government on 20 February 1959, which also ordered to destroy all aircrafts and research. Arrow was one of the most technically successful product and also one of the greatest mysteries in Canadian history. The reason for the cancellation has been widely discussed by…
