How to Build an AI Data Center

Published: 10 June 2024

Tags: ai, hardware

Brian Potter explains the key aspects of constructing an AI data center, focusing on the unique challenges and design considerations compared to traditional data centers. He highlights the increased importance of power density, cooling efficiency, and network infrastructure for supporting AI workloads.

Some highlights:

• Power Density and Cooling: AI data centers require significantly higher power density and cooling capabilities than traditional data centers to support the energy demands of AI hardware.

• Network Infrastructure: Enhanced network infrastructure is crucial for AI data centers to handle the immense data throughput and connectivity needs of AI systems.

• Physical Space and Layout: The physical layout of AI data centers must accommodate the specific heat distribution and airflow requirements of AI equipment, leading to different design considerations compared to conventional data centers.

React, Electron, and LLMs have a common purpose: the labour arbitrage theory of dev tool popularity

Published: 2 May 2024

Tags: frameworks, philosophy

Baldur Bjarnason critiques the use of frameworks and standardization in the context of labor arbitrage, arguing that these technologies often prioritize cost savings over quality and performance. He suggests that the pursuit of cheaper development methods can lead to suboptimal software solutions.

Some highlights:

• Technological Trade-offs: Bjarnason discusses how the adoption of frameworks can lead to compromises in software quality and performance due to a focus on reducing development costs.

• Labour Arbitrage: The article highlights the impact of labor arbitrage in software development, where companies leverage global labor markets and cost-cutting measures, often at the expense of product excellence.

• Sustainable Practices: Bjarnason calls for more sustainable software development practices that balance cost with quality, advocating for thoughtful use of technology that aligns with long-term goals rather than short-term savings.

The Developer's Guide to User Management

Published: 25 March 2024

Tags: sponsored, auth

WorkOS published an extensive guide on building modern day user management, diving into various auth topics like SSO, MFA, and even user provisioning.

Some highlights:

• Session management is a foundational piece of user management but is complex to build. Devs need to consider cookie-based vs. JWT-based auth and how to persist login state information for users that are part of multiple orgs

• At the 201 level, things like bot detection and org auth policies become more relevant

• 301 topics include invitation flows, email verification, and more

Failing at Combinatorics with Haskell

Published: 10 June 2024

Tags: haskell, math, functional

Chris explores the challenges and solutions involved in solving a combinatorial math problem using Haskell. The article delves into postfix notation for simplifying arithmetic expressions and presents a detailed implementation for generating and evaluating these expressions in Haskell.

Some highlights:

• Postfix Notation Simplification: Chris uses postfix notation to simplify the handling of arithmetic expressions, avoiding the complexity of parentheses and leveraging the order of numbers and operators.

• State-based Emission: The article introduces a state-based approach to generate valid postfix expressions by tracking previously emitted digits and operators, ensuring the correct formation of arithmetic expressions.

• Combinatorial Complexity: Chris demonstrates the combinatorial explosion when evaluating expressions over increasing digit ranges, illustrating the computational challenges and providing empirical runtime estimates for different digit intervals.
