What I like about interviews is that they can directly show your weaknesses to you. When you think about a friend, girlfriend, parents and even your teacher, they all might say that you are great. Well, maybe you are really good at what you do but hearing it from someone who has objective views on you is very effective. It is all about trade offs. Here, objective views refer to from the perspective of conducting interviews to you, it will not be fair to have your closest friend as interviewer. All judgment is done based on your technical skills rather than personal thoughts. Sure, you do not want to hear bad judgments from your close friends, girlfriend or parents. However you might still want to see your value in industry independently from what your friends, parents think about. Therefore, I started interviewing with companies to find my weaknesses and desired job. ...

Imagine a scenario where you have a monolithic application which uses a config file to store information about log directories, cert dirs and other service information. As an example to it following config file (- it is taken and modified from Haaukins project which I work on- ) can be considered: host: http: myapplication.mrturkmen.com port: insecure: 8080 secure: 8081 tls: enabled: false certfile: "/home/mrturkmen/certs/cert.crt" certkey: "/home/mrturkmen/certs/cert.key" cafile: "/home/mrturkmen/certs/ca.crt" files: ova-directory: "/home/mrturkmen/ova" users-file: "/home/mrturkmen/configs/users.yml" exercises-file: "/home/mrturkmen/configs/exercises.yml" frontends-file: "/home/mrturkmen/configs/frontends.yml" prodmode: true vpn-service: grpc: "vpnservice.mrturkmen.com:4000" auth-key: random-auth-key sign-key: random-sign-key tls: enabled: true certfile: "/home/mrturkmen/certs/cert.crt" certkey: "/home/mrturkmen/certs/cert.key" cafile: "/home/mrturkmen/certs/ca.crt" In this config file we have some set of keys which are defined to be used inside the application, however let’s say we would like to update some values from the config file. Then in normal cases (-if no hot reload kind of function implemented- ), user needs to restart entire application. It means application will have some down time, it may be less or more however it is not good way of doing it, in particular to update only a value from config file. ...

Concurrency in Go Concurrency in Go, makes Go programming language very unique and attractive compared to other languages, in this section I am going to share the notes which I took when I was watching coursera video series. If you did not already check previous post on Go, it could be helpful to check it out first. Go Notes (OOP) Specialization serie is Programming with Google Go ...

In this post, I would like to share the notes that I took when I was completing following Go series education on Coursera. I can recommend it for anyone who would like to get rapid introduction to Go programming. Programming with Google Go I should admit that although it looks fancy, nothing can be compared to actual development and contribution to open source projects. The course itself is quite interesting and contains very handy exercises regarding to Go development mentality. I would recommend it for anyone who has some interest in Go development and do not know where to start. ...
