jw887c··on EVs are depreciating faster than gas-powered cars
You are the poster child for depreciation. You might have received more utility than the price you paid but at the end of the day, that dollar value once you gave it away was $0
jw887c··on Python Modern Practices
>Avoid using Poetry for new projects. Poetry predates many standards for Python tooling. This means that it uses non-standard implementations of key features, such as the dependency resolver and configuration formats in pyproject.toml files.

What? This is the first I've heard of this.

jw887c··on Mpire: A Python package for easier and faster multiprocessing
Multiprocessing is great as a first pass parallelization but I've found that debugging it to be very hard, especially for junior employees.

It seems much easier to follow when you can push everything to horizontally scaled single processes for languages like Python.

jw887c··on Is technical analysis just stock market astrology?
Yes
jw887c··on Airflow's Problem
>We were on AWS Managed Airflow, but to stay on it and have a solid platform, I would have been writing Github Actions for CI/CD, standing up ECR and IAM roles with Terraform, setting up EKS to run Kubernetes jobs, managing infra monitoring with Datadog, etc., etc.

This sounds like an issue not with Airflow but with integration.

jw887c··on Amazon Redshift re-invented
This is the case for most column oriented data warehouses (including BigQuery, but Snowflake does allow for 1 PK). It's just the nature of the technology.
jw887c··on A naked skydive inspired a way to keep pilots oriented in flight
Skydiving is cold. Skydiving while naked sounds freezing
jw887c··on Flaw of Averages (2002)
My favorite flaw of averages isn't even mentioned in this article. It's the aggregation of averages across covariates. The more covariates (higher dimensions) your problem has, the less likely the population will exist "in the average".

This was explored in a famous study of Air Force pilots and when measuring across 10 different dimensions, found that 0 pilots were "average" across all 10.

>There was no such thing as an average pilot. If you’ve designed a cockpit to fit the average pilot, you’ve actually designed it to fit no one.

jw887c··on Religious fervour is migrating into politics
Great tip.
jw887c··on A Brief History of the Hedge Fund
A $40B manager once told if I could deliver 6% annual return with 1% volatility, he would give me all his money. Yeah, they want as little volatility as possible.
jw887c··on Amazon S3 Object Lambda
GCP is behind. They're are behind in niche services to be fair but behind nonetheless. Nothing that prevents building similar services, but coming from AWS, I routinely feel frustrated by lack of finesse and comparable offerings. IMO, GCP's greatest benefits over AWS are:

* BigQuery

* Tighter k8s integration with GKE

* Single message service (PubSub)

Unless BigQuery is your first class citizen, I would avoid GCP.

jw887c··on Argo Workflows v3.0
If you prefer yaml > Python or if you prefer installing one k8s app instead of managing all of the airflow dependencies (scheduler, webserver, workers, etc)
jw887c··on Laptop stolen from Pelosi's office during storming of U.S. Capitol, says aide
Special room for classified stuff. Even once you're inside the classified room (usually windowless and behind a locked keypad) a lot of stuff is also behind locked filing cabinets.
jw887c··on Poor evidence that Q-tips are harmful
Oh definitely. I have TONS of buildup after a few days. There is a (anecdotally) significant difference in hearing ability post cleaning via q-tip. If I don't use the q-tip, Airpods get very gross within a few days.
jw887c··on Private Equity Investing Now Allowed in 401(k) Retirement Funds
Depends on which part of the ladder you are on. If you're the fund manager of a big fund, you got rich. If you're the LP of growth seed rounds, you probably got rich. If you're the LP of later stage rounds, you probably didn't get rich.
jw887c··on Boeing cutting more than 12,000 U.S. jobs with thousands more planned
Ex-aerospace engineer here, now software developer. This is one major reason why a lot of younger folks at Boeing leave (at least the ones with a more broader view of their industry).

A lot of "engineers" at Boeing are actually project / program / product managers and can pivot to similar roles at tech firms. The stress engineers have it a lot tougher.

jw887c··on AI Gahuku: AI Generator Will Turn Your Photos into Renaissance Paintings
Yeah this doesn't work for non-white folk. Just makes us look like white folk
jw887c··on SoftBank expects $24B in losses from Vision Fund, WeWork and OneWeb
Softbank is every VC/PE's analyst and associates punching bag
jw887c··on Lets Use ML for Insights
I view it as:

Explainable models = statistical models (regression / multilevel models).

Black box models = machine learning (tree based models).

AI = black box models for computer vision / NLP.

jw887c··on 23andMe lays off 100 people as DNA test sales decline
Its not surprising when you realize how bad wealth inequality has made investors searching desperately for any place to put money.
