One day, it became necessary to have a tool to easily observe resource consumption trends of a Go process. I’m aware that there are tons of APM tools out there; also, Go has enough profiling tools including pprof.

I recently had the opportunity to encrypt/decrypt stuff using AES, but I didn’t know it inside out well. I couldn’t help but be curious about how it is working, and I realized my mind could only be satisfied by digging deeper into its implementation.

As reported by DORA’s The Accelerate State of DevOps Report, elite performers deploy code to production a bunch of times a day,

An Introduction to Progressive Delivery

What do you refer to when you’re curious about the Go AST? A document? Source code? While reading the documentation helps you understand it in the abstract, you can’t see how APIs relate to each other, etc.

Take a walk the Go AST

The analysis of source code at the syntactic level can help you with your coding in a variety of ways. For that, the text is almost always converted to AST first to make it easier to handle in most languages.

Things That Could Drive Me Into a Nervous Breakdown

Unfortunately, as mentioned earlier I was not able to get into Google Summer of Code 2019.  Despite things never worked out as my expect, I do not despaired at all.

Incredible reasons I make a recommendation to apply to GSoC despite never got accepted

Necessity of distributed tracing Since distributed architecture such as Microservices are handled across multiple services, it’s difficult to keep track of communication between services.

Realization of distributed tracing by Envoy

Now, the architecture called Service Mesh is attracting attention in the Microservice industry.There are various products for realization, but I made a small control-plane called sxds.

The term gRPC became very famous, and articles such as “Introducing gRPC in house” and “How to build gRPC server” can now overflow.

Why was gRPC born?
