The Fetch API provides modern interface for HTTP requests returning promises. I use fetch(url) to make GET requests that resolve with Response objects. The response.json() parses JSON data asynchronously. POST requests need method, headers, and body o

Soft deletes mark records as deleted without removing them from the database, enabling recovery and audit trails. I add SoftDeletes trait to models and a deleted_at timestamp column. Calling delete() sets deleted_at instead of removing rows. Soft-dele

For image work, I start with a compact CNN before reaching for heavy pretrained models. That baseline helps confirm whether labels, normalization, and augmentation are sane. It also makes failure cases easier to explain because the model architecture

Service objects extract complex business logic from models and controllers, following Single Responsibility Principle. I structure services with a clear public interface—typically a call method. Services handle multi-step operations, external API call

Spring Boot handles multipart file uploads efficiently. MultipartFile represents uploaded files. I validate file types, sizes, and content. Files are stored locally, in cloud storage (S3, Azure Blob), or databases. Streaming large files prevents memor

Health checks verify container readiness and liveness. The HEALTHCHECK Dockerfile instruction defines container-level checks. Kubernetes readinessProbe gates traffic routing—failing probes remove Pods from Service endpoints. livenessProbe detects dead

Geospatial data represents geographic locations and shapes. I use PostGIS for spatial queries. Point data stores coordinates—latitude, longitude. LineString represents paths. Polygon defines areas. Spatial indexes (GIST) enable fast proximity queries.

I avoid handing broad cluster access to workloads just because it is convenient during setup. Service accounts should have the minimum verbs and resources needed for the job, nothing more. Over-permissioned cluster identities make post-exploitation mu

Laravel notifications send messages across email, SMS, Slack, database, and more via a unified API. I create notification classes extending Notification with channel-specific methods—toMail(), toDatabase(), toSlack(). The via() method determines which

Blade components create reusable, self-contained UI elements with their own logic and styling. Anonymous components are simple Blade files, while class-based components have PHP backing classes. I pass data via attributes—<x-alert type='success' /&

XML is still a problem when parsers are left in permissive mode. I disable external entities, refuse network fetches, and prefer simpler formats unless XML is required by an external integration. Attackers love parser defaults that nobody revisited af

Pseudo-classes select elements based on state like :hover, :focus, :active, and :visited. I use :nth-child() and :nth-of-type() for pattern-based selection. The :first-child, :last-child, and :only-child target specific positions. Form pseudo-classes
