Subject: [Action Required] API Migration Timeline

Hi Team,

Following up on the API migration discussion.
Here's the proposed timeline:

Phase 1 (Week 1-2): Deprecation notices
Phase 2 (Week 3-4): Parallel running old/new APIs
Phase 3 (Week 5): Old API shutdown

Please review and share any concerns or adjustments.

Key questions:
1. Are there dependencies we're missing?
2. Do we need to coordinate with frontend?

Looking forward to your feedback.

Best regards,

Top 10 Developer English Mistakes
================================

1. Missing articles (a/the)
   X: "I fixed bug in login page"
   O: "I fixed a bug on the login page"

2. Singular/plural confusion
   X: "There are many informations"
   O: "There is a lot of information"

3. Tense confusion
   X: "I already fix this issue"
   O: "I've already fixed this issue"

4. Preposition misuse
   X: "I'm working this feature"
   O: "I'm working on this feature"

5. Direct translation errors
   Unnatural: "Let's do our best fighting!"
   Natural: "Let's do our best!" / "Good luck!"

6. Overusing "I think"
   Variety: "I believe", "I'd suggest", "In my view"

7. Yes/No confusion (negative questions)
   Q: "Don't you think this needs refactoring?"
   "Yes" = I agree it needs refactoring
   "No" = I don't think it needs refactoring

8. Missing subject
   X: "Is good idea"
   O: "That's a good idea"

9. Active/passive confusion
   X: "The bug was happened"
   O: "The bug happened" / "The bug was caused by..."

10. Overly direct commands
    X: "Please fix this" (can sound cold)
    O: "Could you please fix this?"

Anki for Developer English
================================

Principle:
  Based on the Ebbinghaus forgetting curve
  Review at increasing intervals: 1d, 3d, 7d, 15d, 30d...
  Minimal time for maximum long-term retention

Anki Card Examples:

[Front] What does "refactor" mean?
[Back] Improving code's internal structure without changing
       external behavior.
       "We need to refactor this module to reduce complexity."

[Front] What does "deprecate" mean?
[Back] Marking something as no longer recommended
       (but still functional).
       "This API endpoint has been deprecated since v3.0."

Recommended Anki Decks:
  - Technical English vocabulary (500 words)
  - Code review essential phrases (100)
  - PR/Issue writing patterns (50)
  - Meeting English expressions (100)

Daily Routine:
  Morning 10 min: 10 new cards + review
  After lunch 5 min: Review only
  Before bed 5 min: Review only

English Learning Habit Stacking
================================

Connect existing habits + English learning:

While drinking morning coffee -> Read 1 English newsletter
On the commute -> 15 min English podcast
After lunch break -> Review 10 Anki cards
Walking home -> 15 min English audiobook
Before bed -> Read 1 English tech blog post

Core Principles:
  1. Start tiny (2-minute rule)
  2. Same time, same place
  3. Anchor to existing habits
  4. Track visibly (streaks)
  5. Never miss twice ("2-day rule")

Learning Streak Strategies
================================

[ ] Duolingo streak: 1 lesson daily (min 5 min)
[ ] Anki streak: Daily review (min 3 min)
[ ] Reading streak: 1 English article daily
[ ] GitHub streak: English commit messages daily

Streak Tips:
  - Set the minimum bar low ("1 Anki card" counts)
  - Enable app notifications
  - Share streaks with friends/colleagues
  - Milestone rewards (30 days, 100 days, 365 days)

When a streak breaks:
  - Don't beat yourself up
  - Restart the same day
  - Consistency matters more than perfection

Micro Goal Strategy
================================

Bad Goal: "Master English"
  -> Too vague, impossible to maintain motivation

Good Micro Goals:
  This week: "Write 5 commit messages in English"
  This month: "Read 10 English tech blog posts"
  This quarter: "Write 5 PRs in English"
  First half: "Introduce myself at an English meetup"
  This year: "Give a lightning talk in English"

Reward yourself at each milestone!

What Is the Intermediate Plateau?
================================

Beginner -> Intermediate: Rapid growth (3-6 months)
  New words, new grammar constantly building

Intermediate Plateau: Growth seems to stop (6-18 months)
  - Basic conversation is fine but deep discussion is hard
  - Can skim docs but miss nuances
  - Can listen but struggle with fast speech
  - Feels like "I'm not improving anymore"

Causes:
  - Staying in the comfort zone
  - Consuming only the same type of content
  - Insufficient output (speaking/writing)
  - Lack of feedback

Plateau Breakthrough Strategies
================================

1. Step Outside Your Comfort Zone
   - Consume content outside your tech domain
   - Read articles with 20%+ unknown words
   - Listen to faster-paced podcasts

2. Increase Output
   - Write 3-line English journal daily (tech-related)
   - Write 1 English blog post per month
   - Present in English study groups

3. Get Feedback
   - Corrections from online tutors
   - Use Grammarly for writing
   - Request reviews from native colleagues

4. Diversify Input
   - Listen to different accents (British, Australian, Indian)
   - Non-technical content: novels, essays
   - Movies/shows with English subtitles

5. Reset Clear Goals
   - "In 3 months, give a tech talk in English"
   - "In 6 months, apply with an English resume"
   - The more specific, the better for motivation

Japan Tech Opportunities
================================

Advantages:
  - Geographically close global opportunity

Technical Interview English Patterns
================================

[Understanding the Problem]
  "Let me make sure I understand the problem correctly."
  "Can I ask a few clarifying questions?"
  "So the input is... and the expected output is..."

[Explaining Your Thinking]
  "My initial approach would be..."
  "Let me think about the time complexity here."
  "I'm considering two approaches: ... and ..."
  "The tradeoff between these is..."

[During Coding]
  "I'll start with a brute force approach."
  "Let me handle the edge case where..."
  "I'll use a hash map to improve lookup time."

[Testing]
  "Let me trace through with a simple example."
  "Edge cases I should consider are..."

[When Unsure]
  "Could you repeat the question?"
  "That's a great question. Let me think."
  "I'm not entirely sure, but my best guess..."

Practice:
  - Solve LeetCode problems while explaining in English
  - Pramp (free mock interviews)
  - Practice in front of a mirror/camera

Cultural Differences in Global Collaboration
================================

Communication Styles:
  - Some cultures are indirect (Japan, Korea)
  - Others are very direct (US, Netherlands, Israel)
  - Both are valid; adapt to your audience

Practical Tips:
  - Respect time zones (schedule in UTC)
  - Prefer async communication (for global teams)
  - Be careful with humor (cross-cultural misunderstandings)
  - Use "I believe/suggest/recommend" for nuance
  - Written communication tends to be more formal than spoken
