Let’s talk about Design Patterns 👇 Design patterns are standard ways to solve common software design problems. Layman's Explanation (Real-life analogy) Imagine ordering a custom burger 🍔 at a restaurant. You could just say: “Give me a burger,” and get a plain one. But what

This is the way
African startups should stop defaulting to AWS and Kubernetes. Get a VPS on Hetzner, deploy with Coolify, and start experimenting until you start making money. Oh, and when you do start making money, still stay there!

419 errors are common in full-stack apps like Laravel. They happen when a CSRF token expires. Each form includes a time-based token, so if the page sits idle too long before submission, the token becomes invalid and it returns a 419 error.
Who has ever seen a 419 before? I’d read about it in the past when I was learning the fundamentals, but I’d never seen it in action until I came across it during a mobile app pentest this year 😅

someone like @ola_otesile don traumatize you people this post for don do million views... Well I wish you the best Desicodes👌🏾
Crazy how it starts with : " let me just learn HTML".....and ends with this. Proof that slow progress is still progress. Alhamdulillah for the journey 🙏

URL shorteners are a great way to learn system design. They take a long URL via POST, store it, and return a short version. Scaling it to TinyURL level requires careful architecture. High-level flow: Client → Load Balancer → App Server → Cache (Redis) → DB 1/🧵
Why URL Shorteners are Great for Beginners A URL Shortener hits the sweet spot because it is simple enough to finish but complex enough to learn real skills. You get to practice: - REST API design (POST to create, GET to redirect) - DB operations - unique ID generation

Edge cases & optimizations: Custom aliases with uniqueness checks TTL for temporary links Analytics via Kafka queue → DB Security: sanitize URLs, HTTPS, prevent open redirects Monitoring: Prometheus alerts on cache misses >5% 5/🧵

Short keys are 6–8 characters, giving ~56B combinations for 6 chars. Keys are generated randomly, checked in Redis, then DB for uniqueness. Rare collisions are handled by regenerating the key. Randomness ensures scalability without collisions. 4/🧵

Redis caches popular short→long URL mappings with TTL, speeding redirects and reducing DB load. NoSQL DBs (MongoDB, DynamoDB) store all mappings durably. Read-heavy, horizontally scalable systems benefit from this setup. 3/🧵

At scale (billions of URLs, millions of redirects/sec), redirects are read-heavy and shortenings are write-light. Clients hit API endpoints for shorten/redirect. Load balancers distribute traffic across multiple servers to handle load efficiently. 2/🧵

New Age parenting 😂🙃
So a child in my class brought food to school today but didn’t touch it. I asked why, and he said their house help hasn’t returned from Christmas break and the food his mummy cooked is not sweet. Now, in my school, if a child doesn’t eat and you don’t report it or inform the

I know we used to write code by hand back then, but do cloud engineers and cybersecurity folks also have to memorize all those Linux commands? 😂🔥

Termius might be the best SSH client I’ve used in a long time. Easy VPS access, modern UI, snippets, and smooth server management, also support multiple servers.
