Gampangnya, Variable adalah tempat kita menyimpan nilai yang nantinya bisa dipakai kembali. Misal kita ingin menampilkan data Nama Lengkap dari Siswa. Bisa saja langsung tampilkan seperti ini: <?php echo "Budi Sucipto"; ?> Hasil yang akan tampil adalah: Budi Sucipto Tapi bayangkan jika Nama Lengkap tersebut dipakai lagi 10x di tempat yang berbeda. Mungkin kamu akan berpikir untuk "Copy Paste
This technical post walks through the design and implementation of Secure Playground: a local web app that simulates prompt-injection attacks against large language models and demonstrates simple defenses. Provide a minimal, reproducible environment to test payloads and defensive strategies. Make it easy to add new providers and run mutation-based red-team experiments. Offer a leaderboard and scor

This is Part 1 of a two-part series. Part 2 (coming soon): Connecting to spoke clusters from a controller using multicluster-runtime, driven by ClusterProfile. The Cluster Inventory API (multicluster.x-k8s.io) is driven by SIG-Multicluster and centered on the ClusterProfile resource. It only delivers value when something produces those ClusterProfiles. That something is a cluster manager. Today, t
When developers travel, we usually prepare the obvious things. Laptop charger. But there is one dependency that is easy to underestimate until it breaks: mobile internet. A trip to China makes this especially obvious. Not because China is hard to travel in, but because so many basic interactions are mobile-first: navigation, translation, ride-hailing, hotel communication, ticket confirmations, pay
As developers, we often have a problematic relationship with primitives. We use a string for an email, a float for a price, and an int for a status. This is what we call Primitive Obsession—and it’s one of the common reasons why PHP codebases gradually become hard to maintain. If you’ve been following my series on Refactoring & Patterns, you know I’m a fan of the Introduce Parameter Object pattern
We've been there. JSON Schema gets hard to write as soon as your payload is non-trivial. Conditional logic, cross-field rules, business invariants, and at some point we stop writing contracts at all. We go code-first, generate the schema from annotations, and end up with 200 lines very few understand, and error messages referencing paths like #/properties/items/allOf/0/then/Then that map to nothin
