Reddit started as a monolithic Python application and has evolved its architecture into smaller microservices in Golang. It replaced database snapshots with real-time data replication using Kafka. Reddit has a dedicated metadata store built with AWS Aurora Postgres and it uses Flink Stateful Functions for modern rule-based content moderation.
This tutorial teaches how to use Next.js Server Actions for manipulating data. Server Actions, combined with React Server Components (RSC) and the App Router, can be used to edit entities within the database without the need to convert Server Components to Client Components for database interactions.
GitHub engineers use GitHub Copilot to semi-automate repetitive tasks like protobuf ID number generation. It also helps them stay focused by generating regular expressions on the fly. GitHub Copilot can be used for documenting code properly.
Simpler code is easier to understand and manage. Establishing clear design goals and non-goals can prevent over-engineering when complexity creeps in. Using less powerful tools can sometimes lead to simpler solutions as the constraints force less complex designs.
Great debuggers follow systematic processes rather than haphazardly tweaking code. They constantly form and test hypotheses, take breaks, and document their learnings from debugging.
Gemini Code Assist offers AI-powered assistance to software engineers in their IDE, similar to GitHub Copilot. It is available to try at no cost until July 11.
Airbnb has open-sourced Chronon, which is an open-source end-to-end feature platform that allows machine learning teams to easily build, deploy, manage, and monitor data pipelines for machine learning. It’s currently used by Airbnb and Stripe for major use cases internally.
DrawDB is a database entity relationship editor right in the browser. It can be used to build diagrams with a few clicks, export SQL scripts, and more.
Datadog's Real User Monitoring (RUM) package has an API that can lead to sensitive user data being accidentally sent to unintended domains. The "site" parameter can be confusing - developers can easily mistake it for their website domain. Instead of defaulting to Datadog's data intake domains, the RUM package constructs a new domain based on the provided "site" value, which could potentially send data to a domain the developer doesn't control. This happened to a company called Corporate Clash, where a misconfiguration led to user data being sent to an unauthorized third-party domain.
Google’s new Gemini Code Assist is an AI-powered coding assistant that helps programmers streamline development tasks. It runs within popular IDEs and can generate code, explain existing code, and assist with large-scale codebase changes. However, similar to GitHub Copilot, it can’t write code completely by itself and will probably need developer oversight to be fully effective.
A list of software bugs and outages that occurred on February 29th, 2024, including problems like payment terminal failures at gas stations and minor glitches in weather apps.
The US Army has announced a new policy for agile and lean software development practices.
zx is a tool for writing complex scripts in JavaScript. zx version 8.0.0 makes it smaller, faster, and adds new features like easier command handling and better process control, but changes some defaults and removes the SSH API.
Google has announced Axion, a new custom-designed Arm-based CPU for data centers that is meant to be more performant and energy-efficient compared to existing x86 and Arm-based solutions.
