For every problem, practice:
Requirements
→ Scale estimation
→ APIs
→ Data model
→ Architecture
→ Caching
→ Queues
→ Database
→ Failure handling
→ Trade-offs
Don't just memorise the architecture.
Pick one problem and try designing it yourself
before looking at the solution.
That's where the real interview preparation starts.
Who created all our Superheroes?
How is it that ONLY "they" can create Superheroes?
Anyone can, however with "their" media monopoly do "they" only put forward work from "their" own people.
Intellectual gatekeeping based on ethnicity.
Thank you and Follow my CoHost @InsideWithSam too 🫡
Omarchy Quattro is out!! This is one of the greatest software releases in my professional career. I hope you enjoy using it just as much as I did building it ✌️ https://t.co/81wLStgH7P
الفرق بين الجيل الحالى من الفنانين والجيل الماضى يتلخص فى الحوار ده 👇
لما سمعت كلام الفنان الجميل عمر الشريف افتكرت اتنين فنانين من الجيل الحالى كانوا قاعدين في برنامج بيتباهوا ويفتخروا أن ولادهم عمرهم ماشافوا مناطق شعبية وأنهم مش بيخرجو أولادهم خارج نطاق مناطق زى التجمع الخامس وزايد 😐😶
Only if education could be this interactive ❤️🔥
I've had a looong wish to build something genuinely useful through vibe coding, and I finally did it.
A 3D human anatomy application built with @threejs using GPT 5.6 Sol.
It all started with a single design image that I created using GPT Image 2.0. I then used it to generate every 3D organ image, one by one.
Next, I converted each of those images into 3D models using @tripoai (and no, they didn't sponsor this 😄).
After that, I opened Codex, wrote a master prompt based on the design, and gave it the prompt, the design image, and all the 3D models.
Codex built the first version beautifully, but there was one big problem.
Every single 3D model was nearly 120-150 MB. That obviously wasn't practical for the web and was giving a performance of 16fps.
After a few iterations, Codex optimized each model down to roughly 2–5.5 MB while preserving the visual quality, reducing the total asset size from ~900 MB to just 28.6 MB. And each model loads on demand.
Along the way, Codex also generated those anatomical illustrations showing where each organ sits in the human body, and even created the interactive hotspot markers that explain different parts of every organ. It handled all of that.
The process wasn't exactly one shot, but it also wasn't difficult. You just have to do it step by step.
It genuinely felt like building something that could make learning anatomy much more engaging.
The inspiration came from @DilumSanjaya's 3D animal plant cell project. I remember seeing it and thinking, "I want to build something like this one day."
And I did it :D
