I've started a 25-day series on Scaling and Architecture.
One topic per day.
As a Principal Backend Engineer with 12+ years of building systems at scale, I want to break down every concept I wish someone explained to me earlier in my career.
Day 1 was Load Balancing.
Today is Day 2: CDN.
Follow along if you're serious about system design. This will be worth your time.
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.
If you're learning system design bookmark this thread, you're going to get a lot of learning from this.
Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use.
Its capabilities exceed those of any model we’ve ever made generally available.
President Trump is undefeated in the stock market.
On May 8th, President Trump told everyone to "go out and buy a Dell."
19 days later, on May 27th, Dell was awarded a $9.7B contract with the US Pentagon.
Today, Dell, $DELL, reported stronger than expected earnings and the stock surged +30%.
Dell's stock is now up +80% since May 8th, adding +$120 BILLION in market cap.
Truly unprecedented.

I seriously have no words to describe what I JUST watched!!
Every single episode feels like a cinematic movie!!
The animation and visuals in this series are UNBELIEVABLE
