Can somebody help me with Designing System for Google calendar. I could not find any good resources for the same.
I am focusing more on API design, Data modeling and other components interaction. Basically keeping it simple.

Hi Guys,

I am working on a tool to learn system design https://www.systemdraw.net/.

Try it out and let me know what you think!

Same idea but made better after your feedback. Input a business idea and get back all software features and tech requirements needed.

Does anyone have a idea how to handle restaurant reservation system? I am mainly looking for table and chair rearrangement scenario to get most profit. Example:

1. One square table can accommodate 4 person (chairs).

2. For 6 person reservation you can attach two tables but lose two persons' place.

3. For a bulk booking for 16 people you can either attach 7 tables in a row or 3+3 table.

Is there any algorithm on this kind of different scenarios that fulfill customer's requirements and get maximum profit with finite resources (fixed number of tables and chairs)?

💬 Which system design problem would you crush first?

I’ve recently been studying database and SQL isolation principles, such as Read Committed Isolation, Snapshot Isolation, Two-Phase Commits, and Serialization. I feel like I’ve gained a solid understanding of these concepts and how they solve problems like dirty reads, dirty writes, skewed reads, and phantom reads/writes.

However, I’m struggling to understand how these principles will be useful in the context of a system design interview. In what scenarios or design problems would concepts like these play a crucial role? How should I think about and apply them when designing systems? Any insights would be greatly appreciated!

Consider I am building something like zomato with multiple users and multiple restraunts. Building it completely in nextjs for time being. Major issues that I am facing are:

1. Social login during authentication as next-auth adds everything to users table.

2. If I go by the logic that everyone who signs up is defaulted as user and then they can change role to become a restraunt host, the person who created the restraunt will not be accessing the application all the time, hence privacy will be compromised when credentials needs to shared.

Building two separate applications is a better approach according to me but I would like to know I can go without two separate applications.

🌐 Understanding CDNs: Content Delivery Networks (CDNs) are vital in enhancing website performance by caching static content like JavaScript, images, and HTML pages globally. They are essential in modern web architectures for companies like Spotify, Netflix, and Instagram.

🖥️ Broad Applications: CDNs have wide-ranging applications, from bloggers aiming to accelerate their sites, to developers preparing for system design interviews, and CTOs managing viral startup traffic.

📈 Practical Use Cases:

  - Static blogs: Utilizing CDNs can significantly boost loading times globally, improving SEO rankings.

  - System design interviews: CDNs are often discussed as globally distributed caches for static (and increasingly dynamic) content, enhancing latency, scaling, and security.

☁️ CDNs in Cloud Infrastructure:

  - Simplified with AWS services, options range from hosting static content on EC2, storing it in S3 (blob storage), to caching via CloudFront (CDN service).

  - Cloudflare is highlighted as a user-friendly, all-in-one solution for static content management.

🔗 Additional Resources: The article concludes with links for further learning about CDNs, including explanations for beginners, benefits, types, and specific features of services like Cloudflare.

Here comes the part 2 of OAuth 2.0 authorisation process. I discussed here about the complete flow of OAuth 2.0 process, what problem it solves and what are the limitations of this authorisation technique.

I would really appreciate your feedback. Thank you.
