What Is ChatGPT Doing … and Why Does It Work?

Exploring Row Level Security In PostgreSQL


Issue #334



My friend's company is looking for a data science intern, so if you're interested, go for it. Tell him you heard about it from the newsletter, so he knows how good of a friend I am ;)
"i am a biginner in python" -> good luck in your journey dear reader!
I recently closed on fulfilling a big software contract for a company, so that's been keeping me busy. That also means that I have some funds available to me to pay for help on the newsletter. If you're interested in helping me get sponsors or grow the newsletter/community, please reach out to me by replying to this email! I'd also like to find help for curating/making these emails, but in order to do that I'd have to spend some time making my dashboard accessible online via login and that sounds like a lot of work I don't really want to do for something that might not end up working out. I'll think about it though if someone is really interested in doing it.
Anyway last issue before the weekend. Hope you have a good one and here it is!

Stephen Wolfram illuminates how ChatGPT (and all large language models, LLMs) works.
Some highlights:

  • ChatGPT is a neural net that can automatically generate text that superficially reads like human-written text
  • ChatGPT does this by looking for patterns in human-written text and using these patterns to generate its own text
  • It's all based on the probability of what the next word should be

The author dives into how row level security works in postgres.
Some highlights:

  • Unlike other RDBMSs, postgres has a role system that helps separate identity, authentication, and authorization
  • Covers policies, checks, inheritance, partitioning, performance, and more concepts related to the topic
  • It ends with a sales pitch for the company's product, but all of the information beforehand is solid

Alex Mackenzie discusses the new WebGPU API for accelerated graphics and compute.
Some highlights:

  • Compares CPU and GPU
  • Alex uses a lot of fancy words I had to google, like "lionise" and "promulgate"
  • Presents what trends and applications WebGPU may unlock and popularize


How did I do?

* Amazing
* Articles not relevant to me
* Articles were relevant, but badly written
* Summaries told me everything I wanted to know
* I like turtles
