Born in Finland.
→ Got curious about computers on his grandfather's machine.
→ Learned programming on a Commodore VIC-20.
→ Studied at the University of Helsinki.
→ Couldn't find the operating system he wanted... so he built one.
At just 21, Linus Torvalds released the Linux kernel and made it open source.
Years later, frustrated with existing version control systems, he created Git.
Today:
• Linux powers most of the world's servers and cloud infrastructure.
• Android runs on the Linux kernel.
• Every one of the world's Top500 supercomputers runs Linux.
• Git is the foundation of modern software development.
No billion-dollar marketing campaign.
No empire built on closed software.
Just decades of solving real problems and sharing the results with the world.
Few people have changed computing as profoundly as Linus Torvalds.

Day 8/60 - System Design Series 🚀
Data Centers:
Following diagram shows two data centers. In normal operation, users are geoDNS-routed also known as geo-routed, to the closest data center, with a split of traffic x% in US-East and (100-x)% in US-West.
geoDNS is a DNS service that allows domain names to be resolved to IP addresses based on the location of a user.
In the event of any significant data center outage, we direct all traffic to a healthy data center.
Technical challenges:
- Traffic redirection
geoDNS can be used to redirect traffic on the basis of user's location
- Data synchronization
Users from different regions could use different databases as well as caches. In failover cases, traffic might be routed to a data center where data is unavailable. Common strategy is to replicate the data across multiple data centers.
- Test and Deployment
With multi data server setup, it is important to test your website/app at different locations.

Finally achieved one of my 2026 goals.

Mr Ash@ash_twtz
My 2026 targets: - Hit 60K subscribers on my YouTube channel. - Get 6K followers on X with payout. - Switch my job. - Make $3,000/month. - Get $1,000 profit from the stock market. - Bulk +10 kg going to the gym. - Launch a SaaS. - Monetise 2 more YouTube channels. I don’t know exactly how I’ll achieve all of this and I really hope I can hit at least 50% by the end of the year.
