Microsoft M365 Account Management

This guide provides a brief introduction to administering Microsoft 365 using the m365 CLI targeted at new PowerShell users. Many Microsoft 365 administrative tasks can be easily automated with PowerShell and the Microsoft 365 command line interface (cli), such as creating and deleting user accounts, granting and revoking licenses and many others!

The m365 CLI for Microsoft 365 is a Microsoft 365 Platform Community (PnP) project. Microsoft 365 Platform Community is a virtual team consisting of

High Level Objects

The Organization is the Root of the Azure DevOps (ADO)
Projects are the highest level Azure Devops Container -- Everything lives within a project
Teams are groups of people -- managed within a project

Fast sparse, exact KNN Manhattan Distance

Given a 1xN (row) vector and a MxN matrix, the code below calculates the manhattan distance between the row vector and each row in the matrix. It uses Numba for significant speadup.

Currenlty I'm using this to calculate distances between a 1 x 60K row vector and a 64k x 60x matrix (with about 500k non-empty values) in ~ 10ms on a single processor

Learn to Love Tolerate FetchXML

Overview

FetchXML seems to be a quirky subset of the SQL implemented in XML and optimized for UI tasks, including:

the ability select specific fields (foo, b.bar) or all fields (*) from an entity
perform LEFT OUTER and INNER joins
assign aliases to attributes (select a.b as foo) and (joined) entities (left join foo as BAR)

Motivation

Least Recently Used Caching can fail when usage frequency is correlated with object size. For example an address database sharded by City and State would likely have increased activity in the largest shards. The cache may initially contains a random subset of cities (e.g. due to an automated process that runs through cities alphabetically) but can eventually become populated by just the largetst shards due to organic traffic (i.e. user based web traffic).

This code is inspired by this gist

Load and Dump JSON and YAML to / From NamesSpaces

Why

Typed Namespaces ensure object typing is correct in the IDE!

Usage

import yaml

These are a few of my favorite courses on tech topics

General Coding:

Python Concurrency
Nginx: Quikly build high performance servers and proxies

Aside: when writing python packages (not just scripts), consider haveing the phrase "If its name has no dots, you cannot use relative imports" tattooed someplace readily accessible.

Aside 2: In python multiprocessing, you cannot use interactive telatype to interact with subprocesses, so if your subprocess that reaches a a call to pdb.set_trace(), the sub-process will simply hang waiting for a reponse, which can be a real pain to debug
