A short note, that I manually made this list clickable links as an iteration. Please post feedback via GitHub issues.

Notes

Profiling Datadog

• Golang 4kb per stack.
• Heap allocation is ~20% of any golang process.
• Heap GC can invalidate caches.
• CPU profiler interrupts program every 100hz.

Go on mainframes

• First one in 1944 At Harvard (Mark I).
• 70% of Fortune 500 companies use Mainframes.
• 90% of credit card transactions on mainframe.
• 40TB of Ram.
• Survive 8.0 on Richter scale.
• Teams need to be prepared, and embrace iteration.

Web Assembley

• Supports JIT and AOT compilation.
• Deny by default security sandbox model.
• Languages with a larger standard library can impact AOT.
• No longer browser-only.
• Faster than Lambda.
• Really interesting take on WASM as an ultimate application-as-a-service, vs FAAS / Container Microservices and Nanoservices.
  Containers still commonly distribute an entire file-system. Wasm is only concerned with a binary.

Disclaimer

I have not watched all the talks; my notes are by no means comprehensive or the only take-aways.

It was 3AM after several hours when I finished indexing having watched 4:22:00 of the day 1 conference online.

I am a little bit exhausted right now, so my attention is ebbing and flowing.

That is not a comment on the talks, more on biology and fatigue. Personally I enjoyed Day 1 and Day 3 the most.; but i skipped and scanned through both.
