Job​

  • Scrum

    • joined scrum training
      • i had once but i had forgot many elemental things

  • TypeScript

    • i have really good development experience
    • strong static analysis
      • type errors, suggestions, etc.
    • structual typing
      • flexble to use
    • functional style
      • i wish JS supports more functional features
        • lazy evaluation on functions such as map() and filter()
        • if expression, switch expression

  • GCP

    • Firebase
      • i hadn't touch it although i knew the name
      • seems easier to use for simple web apps than using aws
    • i feel it is simpler than aws
      • i don't know that is beacuse i've used aws or aws is complex

  • GitHub Actions

    • parallelized jobs to shorten elapsed time

  • GraphQL

    • tried tutorials of Apollo
    • can we get better development experience using GraphQL with TS?
      • typing by TS and GraphQL is duplicate
      • i feel TS might be enough for type validation
        • after all we have to runtime-validations for values too
      • at least i feel introducing GraphQL doesn't match the cost for the current system

Others​

  • i wanna change my job soon
    • i had no offers still now...
    • i wanna develop softwares more technically difficult
      • bored now
    • recently also interested in infrastructures
      • IaC, system architectures

In Progress​

  • Go Programming Language

    • started learning golang because there are many company adopt golang
    • workspace repo: https://github.com/e5pe0n/gpl
    • Chapter 1 - 7
      • done!
    • for me
      • golang is not simple at all as others say so
        • pointers
        • goroutines and channels
      • i've thought that golang was a low-layer language like C/C++ but was made more easier to treat, but that was wrong; it's high-level language than i think so, truly general perpose language
        • standard library looks large and enough to develop web app
      • one of the good candidates in static typed languages for web app
        • prep to dev is easy; batteries included
          • package manager, linter, formatter, etc.
        • ecosystem and support from vendors is sufficient
          • libraries, cdk, sdk, etc
        • performance
        • compiled to executable binary
          • no need something like JVM
        • good compatible to docker containers
      • i hadn't liked golang, and i don't like it now too even my perspective for golang was changed
        • there are too many places side-effects occur
          • hard to track procedures correctly
            • the more i learn golang, the more i wanna use rust

  • Computer Systems: A Programmer's Perspective

    • Chapter 3 - 8
      • done reading!
      • it seams more clearer about low layer than before
        • processor architectures
        • memory systems
          • registers
          • L1-L3 cache
        • exceptions
    • Chapter 9. Virtual Memory
      • very important but also too difficult
      • mechanism of translation from virtual memory to physical memory is too complicated

honestly i don't wanna push these onto the stack but skills to be able to use instantly needed now for recruit.
