My mother worked in a factory that sewed drapes for film sets before she retired. My brother-in-law used to be an operations manager for a warehouse that rented equipment to film sets.

There is just a very long tail of services and a robust supply chain that is required for most industries to be successful.

I was never a prolific blogger. I do write a LOT internally at work and I write very long messages in group chats.

With the advent of LLMs, I've felt even less need to publish publicly. It's as if an LLM can either produce something higher-quality and more tailored to the reader's context in a shorter period of time. Or the topic I write would be so niche that it should just be in a group chat.

I found the accompanying blog post excellent. In my experience, systems go from a monolith to a distributed monolith to a reliable distributed system. A durable workflow engine is one of the pieces that is required to get to target state.

I'm also currently reading "On the Calculation of Volume". It is fantastic.

Meta-comment about the post. I used to read and write book reviews like this all of the time. Not anymore. ChatGPT and Claude can do a just a good of a job. Now I'm looking for what you think, a unique insight, what did you feel from a book review from a humanoid. LLMs do a fine job summarizing.

Yup.

Woke up at 6am. Child 1 woke up at 7am. Dropped her off at daycare at 8am. All the other children were being dropped off by their dads, too. Full day of work ahead. Dinner at 6pm. Bath at 7pm. Bedtime and story at 8pm. Usually calls with Bangalore from 9pm to midnight but it's Labour Day over there. Sleep at midnight.

Rinse. Repeat.

As others have said, levels and titles are generally for compensation and performance reviews. Each company has their own bespoke ladder but it generally maps to:

  - L1: Intern with undergrad degree
  - L2: Intern with graduate degree
  - L3: Junior
  - L4: Intermediate
  - L5: Senior
  - L6: Staff
  - L7: Senior Staff
  - L8: Principal
  - L9: Distinguished
  - L10: Fellow

Each company has their own numbers and names but it generally progresses like that. Impact and scope scales as you head up the ladder.

L5 or Senior is usually considered a “terminal” role. That means all engineers should be able to get to this role. And people without the headroom get managed out if they can’t get to L5.

Staff+ is usually “special”. It means that people count on you to drive initiatives and you have something special other than just writing code. You are able to make product and business impact.

Distinguished and Fellow are very rare. Large FAANG companies will only have a handful of these engineers. It means you’ve made industry-wide impact like inventing map-reduce or DynamoDB or Kubernetes.

SIMD and data locality. You probably want to check across three vectors simultaneously and load the coordinates next to each other.

I'm guessing here. I haven't written video games in 20 years but struct packing/alignment was super important on the Sony PSP back then.
