“The Coding Machine” at Meta with Michael Novati

Michael Novati, Co-founder and CTO of Formation, recently joined The Pragmatic Engineer to share information about his career and the engineering culture within Facebook.
Meta has created several software architect archetypes, such as the coding machine, to maintain fairness in the promotion of its engineers.
Meta has an engineering-first culture that empowers individual contributors (ICs) and provides career paths in the absence of traditional managerial positions.
The coding machine archetype was modeled after Michael Novati and is typically given to engineers who help move projects forward, refactor code quickly, and launch products that require a team of engineers.
The tenure of employees at a fast-growing scaleup like Meta can have a surprising amount of influence and deadlines must be met, even if it means taking risks and breaking products.
Meta's hiring process starts with a recruiter screen, then a technical screen followed by an on-site interview that includes two more coding interviews, a behavioral interview, and a systems design interview.
Michael advises engineers to find the right job that aligns with their interests and to understand the importance of storytelling to communicate well and share human experiences.
Michael believes preparing for interviews at Big Tech companies and scaleups is no longer a 'nice to have', it’s a necessity for even strong engineers who want to get a job offer.
Meta built much of their infrastructure from scratch, which resulted in custom-made tools and the development of many internal products.
Meta uses product reviews during the development cycle, also known as 'Zuck Reviews,' where Mark Zuckerberg provides feedback before products are launched.

Filling a 10 Million Image Grid with PHP for Internet History

10MPage is an internet history project which involves placing images onto a large grid.
The project requires that each image is approved before placement onto the grid.
Pending tiles need to be placed into the grid table that has an X and Y field.
The original approach was to loop through the grid to find an empty spot and place the pending tile there, however as the grid grew larger, it became slow.
The database table 'Placement blocks' was created to store available blocks, so that larger number of tiles could be handled at the same time.
Adding a pending tile larger than a single placement block is not supported, and the tile has to wait until the grid expands.
This implementation uses Laravel jobs with Laravel Horizon, where multiple workers are handling placements.
The scalability of this implementation is limited by the number of workers and available placement blocks.
The number of tiles that can be placed simultaneously can be increased by scaling up the workers.
The project offers a free experience for users.

How to Load a JSON File in Python

To load a JSON file in Python, you can use the json.load() method if you have a file, or the json.loads() method if you have a string.
Use json.load() to load a JSON file and convert it to a Python object.
If the file contains multiple JSON objects, you can iterate through each line and load them separately using json.loads().
If the JSON objects are not separated by newlines, you can use regex to identify and load each object one by one.

Building bun-tastic: A Fast, High-Performance Static Site Server (OSS)

Bun-tastic is a high-performance static site server that's designed to be fast, flexible, and easy to use. It uses any S3-compatible object storage to store the site files and it's built to run on Bun and its S3 API.
bun-tastic serve multiple static websites from one application, smart path handling with automatic index.html resolution, and globally fast and automatic TLS certificates (if using Fly).
It has a simple configuration through JSON, HTTP/3 support via Fly, Brotli & zstd compression support, and built-in monitoring with Grafana dashboard on Fly.
Built on Bun's native S3 client and web server, it uses zero dependencies and can run on a single machine with 256MB RAM. In terms of speed, bun-tastic performs well in load testing.
If you're managing multiple sites, bun-tastic might be a great option because it provides simplified management and you can tailor it to your individual needs.
While traditional hosting might be cheaper for a single low-traffic site, bun-tastic could save you money or offer more speed if you're managing many sites or dealing with higher traffic.
Tigris provides global caching out of the box and objects cached closer to users means faster subsequent requests.
Any S3-compatible storage will work just fine but using Fly provides additional benefits such as HTTP/3 support, automatic TLS certificates, and global compute for fast and reliable global distribution.
Future plans for bun-tastic include adding CLI for simplified site uploads, 103 Early Hints support, more caching semantics, multi-core configuration, and bot request blocking.
Overall, bun-tastic allows you to self-host static sites on your own terms, with control, flexibility, and top-notch performance.

Java’s Locale.getDefault() Method Explained

Java's Locale.getDefault() method returns a Locale object that represents the default locale of the JVM, which is typically set based on the operating system's settings but can also be customized programmatically.
The getDefault() method is used by many Java APIs as a fallback when no specific locale is provided.
Date formatting, Number and Currency formatting are some of the most common use cases for the default locale.
Java’s resource bundles rely heavily on the default locale when loading localized content, and the default locale is also used in scenarios where applications need to adapt their output to the user’s region.
When formatting dates or numbers for storage or communication between systems, using a fixed locale like Locale.US or Locale.UK provides predictable and uniform results.
The Locale.setDefault() method allows you to programmatically change the default locale, but doing so affects all threads in the application, which can lead to unintended side effects.
Applications that target international users should be tested with multiple locales to verify that formatting, translations, and other locale-sensitive operations behave correctly.
Make it clear in your codebase or documentation where the default locale is being used and why.
In applications where users can choose their preferred locale, make it possible to override the default locale retrieved from Locale.getDefault().
Careful implementation of Locale.getDefault() supports building applications that meet the needs of a global audience.

How the Mechanics of Spring Boot Actuator Health Indicators Work

Spring Boot Actuator automatically activates health indicators based on specific dependencies and integrates them with the /actuator/health endpoint.
Health indicators are registered through Spring Boot’s auto-configuration classes using ConditionalOnClass and ConditionalOnBean annotations.
The HealthContributorRegistry is a centralized registry that manages all health contributors (indicators and aggregators).
When a health check is triggered, the HealthEndpoint retrieves all registered contributors from the HealthContributorRegistry and evaluates their status.
Custom health indicators are implemented by creating a class that implements the HealthIndicator interface. These are automatically registered through Spring Boot when annotated with @Component or defined as a @Bean.
The /actuator/health endpoint aggregates information from all registered HealthIndicator beans and displays their statuses. Developers can control which indicators are included or excluded.
HTTP status codes returned by the health endpoint can be mapped to specific health statuses. Sensitive details in health responses can be selectively included or excluded.
Overall, Spring Boot Actuator’s health indicators provide default and custom functionality to monitor specific components and resources, and can be customized to meet specific requirements.
The framework’s architecture provides a structured yet adaptable way to monitor applications using predefined capabilities with developer-defined logic.
