Why do we use intermediate representations / languages?

Published: 16 June 2024

Tags: compilers, optimization

Edaqa Mortoray discusses the role and benefits of using intermediate representations (IRs) in programming, particularly in the contexts of code analysis, optimization, and translation. He explains how IRs serve as a bridge between high-level code and machine code, enhancing the efficiency and flexibility of software development processes.

Some highlights:

• Intermediate Representations (IRs) are used to bridge the gap between high-level source code and low-level machine code, aiding in translation and optimization.

• IRs facilitate code analysis by providing a uniform framework that supports various programming languages and tools.

• The use of IRs enhances the flexibility of software development, allowing developers to implement optimizations and transformations more efficiently.

Pete Keen writes a ESPHome Protocol Server to drive the addressable LEDs on his house.

Some highlights:

• There are “three ways to get arbitrary devices and entities to show up automatically in Home Assistant”: write a home assistant integration, using MQTT autodiscovery, or using ESPHome firmware.

• includes code

• also includes information on deploying the code

WorkOS has published a guide on how to best integrate single sign-on (SSO) in your app.

Some highlights:

• SSO is a common requirement when organizations first start selling to enterprises

• ​describes the general request flow for a user logging in with SSO

• summarizes how to build SSO from scratch and how to use existing providers

A Logic Circuit Simulator with Cats-Actors

Published: 14 June 2024

Tags: scala, functional

Mark Galea dives into building a logic circuit simulator in scala.

Some highlights:

• “Cats-Actors is a reimagining of the actor paradigm model married with the functional paradigm.”

• The task is to “[develop] a logic circuit simulator that accounts for the internal delays of digital circuits, ensuring that all signals stabilize on each clock tick”

• creates basic components like wires and logic gates, and combined them into more complex structures such as half adders, full adders, and demultiplexers
