I'll forgive the fact that the Bohr atomic model only works for a single orbital electron. (Details)
Apart from the fact that this GenAI can't spell ... AFAIK, Bohr never wore a bowtie (but Thomas Edison did) and Schrödinger never sported a mustache (but Max Planck did). 🥸
Ordinary AI output requires extraordinary human verification. (Apologies to C. Sagan)
DR still in progress for AMZN.com itself ... 🧐

Out of The Queue Comes ... Amdahl’s Law!

RIP James Lovell, commander of Apollo 13 (played by Tom Hanks in the movie of the same name), has died at age 97.
B. All measurements (data) are wrong ... by definition.
The only question is, can you tolerate the wrongness?
If you're not informed how wrong data is, how can you decide?
A. Displaying metrics, errors, etc., is not the same thing as displaying metric errors.
1. How it is (old school top)
CPU usage: 5.79 %usr, 4.51 %sys, 89.68 %idl
2. How it could be (nay, SHOULD be)
CPU usage: 5.79 ± 0.29 %usr, 4.51 ± 0.23 %sys, 89.68 ± 4.48 %idl

GCAP Day 10. What you missed:
❥ Avalanche vs. Paxos coordination scalability
❥ Memcache scalability analysis with USL
❥ Queueing models of Kubernetes control and data planes
❥ Class dismissed 📚 🎓🍻
Never let reality get in the way of a good performance model.
GCAP Day 9. What you missed:
❥ Rate limiting services via Guerrilla queueing models
❥ Performance visualization tools
❥ Zookeeper scalability analysis with the USL
www.perfdynamics.com/Manifesto/US...
GCAP Day 8. What you missed:
❥ Linear vs Dynamic programming
❥ Benchmarking/load testing prats and pitfalls
❥ Prelim discussion about Kefka, Kubernetes
❥ What kind of scheduler is in the K8s control plane?
GCAP Day 7. What you missed:
❥ Python least_squares() seems to be a bloated implementation of codes in the "Numerical Recipes" book.
❥ To apply the USL, use curve_fit() instead.
❥ Multivariate regression: How to reattach (noisy) fingers to amputated daily "numero uno" data
GCAP Day 6. What you missed:
❥ USL scalability analysis

❥ Student gets PDQ 7.0 running on Python 3.12 👏🎉
lnkd.in/gPzzHiez
❥ Homework Q-5 solved (a) analytically (b) cf. with corresponding PyDQ model
- Discussed why analytic calculation was wrong
Ditto for the performance analysis & capacity planning of computer systems in general:
- Assume failure
- Plan for resilience
- Monitor everything
- Analyze and predict performance and capacity
- Have an exceptional performance team of skilled experts

I recently discovered the original 1992 paper where I first introduced the concept of barycentric coordinates for visualizing multiprocessor/multicore performance. www.perfdynamics.com/papers.pdf
More modern renditions (animations) can be viewed here www.perfdynamics.com/Tools/tools....
Yep.
Guerrilla training classes (GCAP) online are brutal.
Despite the rumors, there are no long lunches.
Only performance zealots should apply.
Next class starts July 21, 2025.

Even worse, without access to another phone or computer, you're really screwed. The longer it takes to contact Lyft, the lower the likelihood of ever seeing your phone again.
Thank God it wasn't BART.
