Go 語言延遲初始化 -Lazy Initialization- 最佳實踐
簡介—–在有些資源初始化成本很高，甚至在某些代碼路徑未觸發根本沒有必要初始化，可以將對象的創建、配置等耗時操作推遲到真正需要使用時才執行。延遲初始化實現———-2.1 sync.Oncesync.Once 是 Go 標準庫提供的線程安全初始化工具，確保初始化代碼只執行一次：var (    resource MyResource  // 需要延遲初始化的資源    once ⌘ Read more

18 rules of Software Engineering

  1. You will regret complexity when on-call
  2. Stop falling in love with your own code
  3. Everything is a trade-off. There’s no “best” 3. Every line of code you write is a liability 4. Document your decisions and designs
  4. Everyone hates code they didn’t write
  5. Don’t use unnecessary dependencies
  6. Coding standards prevent arguments
  7. Write meaningful commit messages
  8. Don’t ever stop learning new things
  9. Code reviews spread knowledge
  10. Always build for maintainability
  11. Ask for help when you’re stuck
  12. Fix root causes, not symptoms
  13. Software is never completed
  14. Estimates are not promises
  15. Ship early, iterate often
  16. Keep. It. Simple.

Solid list, even though 14 is up for debate in my opinion: Software can be completed. You have a use case / problem, you solve that problem, done. Your software is completed now. There might still be bugs and they should be fixed – but this doesn’t “add” to the program. Don’t use “software is never done” as an excuse to keep adding and adding stuff to your code.

↳ In-reply-to » Just discovered how easy it is to recall my last arg in shell and my brain went 🤯 How come I've never learned about this before!? I wonder how many other QOL shortcuts I'm missing on 🥲

@aelaraji@aelaraji.com I use Alt+. all the time, it’s great. 👌

FWIW, another thing I often use is !! to recall the entire previous command line:

$ find -iname '*foo*'
./This is a foo file.txt

$ cat "$(!!)"
cat "$(find -iname '*foo*')"
This is just a test.

Yep!

Or:

$ ls -al subdir
ls: cannot open directory 'subdir': Permission denied

$ sudo !!
sudo ls -al subdir
