Achievements

Essentials of Programming Languages
- Re-implemented chapter 3 using SLLGEN
Hacking: The Art of Exploitation
- learned about
  - memory segments
  - the foundation of network again
    - how is the content of a packet in binary

i could take a break
- honestly the first half of May i've been burned out and had no motivation
- that's good once in a while
Hacking: The Art of Exploitation is interesting
- i learned the foundation which is necessary for programming again
- i'm not good at network but i could get interesting in it
- read raw socket implementations
  - all data flowing on network is simply binary: a sequence of bits
    - which is thought that it should be arranged, following a standard like RFC
    - but we can send binary data by any bit arrangement to hack
- some knowledge about network was useful for my job
  - building local DNS server using Dnsmasq to access local web app on Mac by hostname from iPad
wish list
- learning Rust
  - i'm interesting in the lower part of programming
  - i wanna use static typed language
- books
  - Fluent Python 2nd Edtion
    - i read the 1st Edition
      - it was very long but the 2nd is twice longer!
    - honestly, recently i don't like python
    - but many project use python so the demand cannot be ignored
  - Mastering Regular Expressions: Understand Your Data and Be More Productive
    - after that, program is a sequence of strings before compiled
    - handling strings can be a hack
    - and regex is powerful enough to make my development more efficient
