Most engineers learn system design backwards. You don't become good at system design by memorizing diagrams. You become good by understanding the physics of distributed systems. Latency. Durability. Throughput. Availability. Cost. Those 5 forces rule everything. #SystemDesign

@officialABAT Mr. President, your government has to do something about the insecurity in Nigeria. And also the religious leaders, prayers only doesn't solve problems, you have to back it up with actions. Call out the government. #NigUniteAgainstInsecurity

What are the API architectural styles? The diagram below shows the common API architectural styles in one picture: 1. REST 2. GraphQL 3. Web socket 4. Webhook 5. gRPC 6. SOAP

@_rain_miao_ Prompts get stucked, then hallucination begins.

@RichardOlajuwon prompts get stuck

Vibe coding only works when 80% of your effort goes into thinking and planning, and 20% goes into letting the AI execute.

@aitechbrief You have to tell AI what to do and how do it, else they're gonna hit a roadblock fast and start hallucinating

@RichardOlajuwon That 80/20 split is the key: AI speeds execution, but weak specs just produce bugs faster.

We are not the same

The best programming language: English. Language choice doesn't matter anymore. Instead; Master critical thinking. Go hard on testing practices. The best developers aren't loyal to languages. They're loyal to making customers happy.

You need to be good at coding to be good at vibe-coding. When your project hits 30+ files, fundamentals is the only thing that helps you catch AI mistakes.

These 6 codebase taught me more than a CS degree:

@WatcherGuru Finally some good news

JUST IN: Jim Cramer says now is a "chance for people to sell."

How Big 0 works explained: Big 0 tells how much slower the code gets as the input increases. There are best, average, and worst cases for a specific algorithm. Plus, there are Big Os for time, memory & storage efficiency. What else would you add?
