I have shifted to a Tech Lead role for 2 months.
And I've already learned a ton with my team.

These lessons cover a range of topics, from coaching, planning, to technical writing and more

I'll keep sharing these hard-learned lessons on Twitter.
This 🧵 would be an index:

COBE v2: reliably use any DOM elements as markers & arcs. CSS transition, animation, filter, interactivity, ...all just work.

High perf, zero deps, still ~5KB. Coming soon.

𝗧𝗵𝗲 𝗠𝗮𝗻𝗮𝗴𝗲𝗿'𝘀 𝗣𝗮𝗿𝗮𝗱𝗼𝘅: 𝗗𝗲𝘁𝗮𝗶𝗹𝘀 𝗪𝗶𝘁𝗵𝗼𝘂𝘁 𝗠𝗶𝗰𝗿𝗼𝗺𝗮𝗻𝗮𝗴𝗲𝗺𝗲𝗻𝘁

You absolutely need to know the details. If a department head doesn't know their numbers, that's a massive red flag--they're not on top of their responsibilities.

But micromanagement is equally toxic. When you interrogate every decision and dictate every action, you strip away autonomy and turn people into cogs.

But micromanagement always signals that the manager has failed.

Micromanagement is a flashing warning sign that something's broken, and it's always the manager's fault.

𝗦𝗰𝗲𝗻𝗮𝗿𝗶𝗼 𝟭: The person can't be trusted with decisions and needs constant direction. You hired wrong. That's on you.

𝗦𝗰𝗲𝗻𝗮𝗿𝗶𝗼 𝟮: They're capable but you won't let them work. You're the bottleneck, hurting good employees and preventing the company from scaling.

Either way, your best people will leave. People want autonomy. They want to contribute meaningfully, not follow scripts.

The Solution: 𝗠𝗼𝗻𝗶𝘁𝗼𝗿 𝗪𝗶𝘁𝗵𝗼𝘂𝘁 𝗖𝗼𝗻𝘁𝗿𝗼𝗹𝗹𝗶𝗻𝗴

You can know everything without dictating everything. Monitor performance and hold people accountable without micromanaging their process.

If you can't figure out how to do this, get help immediately--a book, a coach, something. Because right now, you're being a terrible manager.

The goal is simple: Stay informed while staying out of the way.

The article below is how I do it:

The BEAM Book 1.0 just dropped!

I was recently recommended this talk, and I really like it! If you develop software as part of a team and use git, check it out (and spread the word, it deserves more views 😉).

@springuper @geekplux Interesting take

但也确实说得通 😂
特别是中层，being pulled in so many directions

FactoryBot is the quickest way to kill your test suite performance with Rails. Our HEY suite runs in <2 mins on a modern Linux machine with over 30,000 assertions. Against a real database! The secret? Rails Fixtures! They're setup once, txn-wrapped for resets, and insanely fast.

@Manjusaka_Lee 我以前也以为从一个公司的技术栈、工具栈能看出靠谱程度

后面发现相关度其实不高
用 GraphQL 的公司肯定有靠谱的，也有不靠谱的（废话
