When I started my Piscine at @Zone01Kisumu his book was one of the major boost that helped me try and learn Go.
It was search a great experience listening to @alextrending at @gophers_africa.
Asante sana and Karibu Kenya.
🔒 Before you replace a lock, profile it and find where the contention really is.
In @alextrending benchmark, 98.78% of the delay showed up at sync.(*Mutex).Unlock, because waiters add the delay and Unlock gets the stack.

📱 p95 latency of 5.8 to 15.7 seconds before optimization.
Paul Okeke and Peter Dada from @moniepoint at #GopherConAfrica2026 on where a tap's time actually goes.
Fewer round trips. Shorter round trips. Smaller payloads. And rejecting bad requests at the edge.

🤖 A rule the agent has to remember is a suggestion. A rule with a test is something it can check on its own.
@_bigzoo at #GopherConAfrica2026 on invariants as the new interface.
Balanced, atomic, exact, append-only, monotonic IDs. Five ledger rules, five tests.

📦 Docker isn't magic. It's Linux primitives assembled together.

@t_starkx : sagas with Temporal, compensation registered first.
Toluwase: synctest, testing a 10 minute delay without waiting 10 minutes.
@alextrending : a good lock is a policy, not just a loop.
ESHU: standardize the path to production, not how every team writes code.

Intoxicating.
I’ve been programming for 45 years, since so was 10. I’ve been a pro game coder for 33 years. Everything from hand coded assembly to UE 5.8. The paradigm shift to agentic coding is intoxicating. It is the biggest productivity jump I have ever experienced.
