🚨🗣 Jamie Carragher on Egypt's Canceled goal by VAR:
🗣"I am telling you that, if that was against another team it would have been awarded as a goal"
"If that was in the premier league, Laliga or Serie A, it would have been a goal even after VAR review, there is a lot of inconsistency lately in this tournament"
Incredible Egyptian goal is disallowed because of a foul far away, then same situation a few minutes later and goal for Argentina not disallowed! No VAR, nothing? FIFA again looks like a corrupt joke, playing favorites for stars.
🚨🗣 Egypt's Coach Hossam Hassan couldn't control himself after full-time:
"I will say what's on my mind regardless of the consequence, this was clearly a rigged match and the whole world saw it"
"And I want to say one more thing, if they want them [Argentina] to win so bad, why call everyone to come and participate?"

How a write-heavy backend slowly kills itself:
Most backends don't die from a single catastrophic failure.
They die slowly.
Every write operation quietly stacking pressure on a system that was never designed to handle it.
By the time you notice, the damage is already done.
This thread explains everything you need to know.

I've been a backend Engineer for 12+ years. Today, I'm a Principal Engineer at Atlassian.
I've designed systems that handle millions of requests. Sat on both sides of system design interviews.
Reviewed more architecture docs than I can count.
Starting today, I'm breaking down the fundamentals of scaling for the next 25 days.

Building an Optimized Chat System Like WhatsApp: A Professional, Step-by-Step Implementation Guide
Building a messaging platform capable of handling millions of concurrent users with WhatsApp-level performance requires deliberate engineering choices in distributed systems, security, and mobile optimization.
This 23-part thread provides a realistic, production-oriented implementation roadmap.
We focus on how actually to build each component. Not just lists.
This assumes a small experienced team and prioritizes reliability, E2E encryption, and efficiency.
