AI Engineering Handbook (Draft)

What is AI Engineering?

AI engineers operate at a higher level of abstraction than Machine Learning (ML) engineers or large language model (LLM) engineers and don't necessarily need to know how to build an LLM or a ML model.

AI engineering builds upon ML systems[^1], but with a focus on large scale, ready made models (aka. base models).

The distinct skills that AI engineers need to know include prompt engineering,

log4j RCE Exploitation Detection

You can use these commands and rules to search for exploitation attempts against log4j RCE vulnerability CVE-2021-44228

Grep / Zgrep

This command searches for exploitation attempts in uncompressed files in folder /var/log and all sub folders

sudo egrep -I -i -r '\$(\{|%7B)jndi:(ldap[s]?|rmi|dns|nis|iiop|corba|nds|http):/[^\n]+' /var/log

React Native + macOS + Clojurescript

Project Catalyst

Since the recent release of Catalina, macOS has shipped with the ability to allow iOS/iPAD apps to run on macOS without any modification via a featureset known as Project Catalyst.

This is exciting, as writing React Native + Clojurescript apps as a target for the desktop is much more compelling than a pure Electron app (imo).

CQRS, Task Based UIs, Event Sourcing agh!

Posted by gregyoung on February 16, 2010

Many people have been getting confused over what CQRS is. They look at CQRS as being an architecture; it is not. CQRS is a very simple pattern that enables many opportunities for architecture that may otherwise not exist. CQRS is not eventual consistency, it is not eventing, it is not messaging, it is not having separated models for reading and writing, nor is it using event sourcing. I want to take a few paragraphs to describe first exactly what CQRS is and then how it relates to other patterns.

CQRS Command and Query Responsibility Segregation

Starting with CQRS, CQRS is simply the creation of two objects where there was previously only one. The separation occurs based upon whether the methods are a command or a query (the same definition that is used by Meyer in Command and Query Separation, a command is any method that mutates state and a query is any method that returns a value).

Realtime Database triggers with Cloud Functions for Firebase - source

This gist contains the source code in my video series about Realtime Database triggers. You can watch the three parts here:

Part 1 (intro, onCreate)
Part 2 (onUpdate, infinite loops)
Part 3 (onDelete, transactions)

index.ts contains the Cloud Functions code, and dialog.ts contains the script to run

-open Utilities -> Terminal
-in the terminal, type: `csrutil disable`
-restart your Mac
-open a Terminal window and type: `systemextensionsctl list`
-It will show something like:

	In JavaScript, objects can be used to serve various purposes.

	To maximise our usage of the type system, we should assign different types to our objects depending
	on the desired purpose.

	In this blog post I will clarify two common purposes for objects known as records and dictionaries
	(aka maps), and how they can both be used with regards to the type system.
