🚨🩵🤍 Lisandro Martínez: “Leo Messi is a massive example because he has suffered a lot throughout his entire career, he has suffered losses and he never gave up”, told ESPN.
“Today he is here at 39 years old, fighting, battling, he has already won everything, he has absolutely nothing left to prove”.
“He is the best player in history, not just in football, but in all of sports. It's madness”.
“And for those of us coming up behind him, how can we not keep fighting if the best of all time does it with this kind of passion? We have to follow behind him in the exact same way”.

Yeah, he made a diss track about Indians instead of just T-Series (probably his most childish move).
But no one can deny... the man dominated social media for an entire decade and now lives a life many people dream of.
Most people think the internet is “fast” because their Wi-Fi signal is strong.
But signal strength and internet speed are two completely different things.
When you open a website, your request doesn’t magically appear on the server. A lot of invisible steps happen in milliseconds:
1. Your device asks a DNS server to translate the domain name into an IP address.
2. Your device establishes a TCP connection with that server.
3. If the site uses HTTPS, a TLS handshake happens to encrypt the connection.
4. Only then does your browser send the HTTP request asking for the page.
5. The server processes it, queries databases, and sends the response back.
6. Your browser downloads HTML, CSS, JavaScript, images, and fonts.
7. Finally, it renders the page visually for you.
All of this happens in less than a second.
So the next time a website feels slow, it might not be your Wi-Fi.
It could be:
• DNS lookup delays
• server processing time
• database bottlenecks
• large JavaScript bundles
• slow third-party APIs
Internet speed is just one piece of a much bigger system.
The real magic is how billions of devices coordinate these steps every second without us ever noticing.
Interviewer:
If a website goes viral and suddenly gets millions of users, what actually breaks first on the backend?
>Claude was used by the U.S. in the Iran strikes
>Iranian missiles hit an AWS data center.
>Anthropic runs Claude on AWS.
>Claude has been down for hours.
Interviewer:
If two users upload a file with the same name to a cloud service, how does the backend prevent collision?
