Let's talk about code reading (teaser)
- 1. let’s talk about code reading
- 7. when did you last talk about code reading?
- 8. most developers never talk about code reading
- 9. yet, code reading occupies some half of developers’ time
- 10. so, not talking about code reading is not talking about half of developers’ time
- 11. so, not talking about code reading is not talking about half of the budget
- 12. so, not talking about code reading is not talking about half of the budget that’s this much
- 13. and, these are just the direct costs of code reading that’s this much
- 14. we cannot afford not to talk about code reading
- 15. why do we need code reading?
- 16. code reading is how engineers gather information
- 17. code reading is how engineers gather information to make decisions
- 18. but, is code reading the best way to gather information?
- 19. code reading is a flexible way to gather information
- 20. code reading is a detailed way to gather information
- 21. yet, code reading is also the most manual way to gather information
- 22. unfortunately, code reading does not scale
- 23. by the way, where does code reading happen?
- 24. code reading happens in an editor
- 25. an editor
- 26. an editor is like a magnifier glass
- 27. an editor is good for details
- 28. an editor is terrible for overviews
- 29. yet, code reading happens in an editor
- 30. code reading does not scale
- 31. let’s see: how long would code reading take if we were to read 250’000 lines of code?
- 32. 250’000 lines of code:
- 33. 250’000 lines of code: reading 1 line in 2 seconds
- 34. 250’000 lines of code: reading 1 line in 2 seconds would require ~1 person-month
- 35. and 250’000 lines of code is a small system
- 36. code reading does not scale even for a small system
- 38. no, code reading is not at all useless
- 39. only, code reading is not the only option
- 40. there are alternatives to code reading
- 41. there are alternatives to code reading and some are quite exciting
- 42. there are alternatives to code reading
- 43. but, to find those alternatives to code reading we have to start talking about it
- 44. let’s talk about code reading a humane-assessment.com concept by @girba
