Case Study: Your API suddenly starts receiving 40k requests per minute from a single IP trying random login attempts against user accounts. Question: How would you protect the authentication system without affecting legitimate users?

yes. where I work, we run 8 mssql shards because we store up to 20 entries per search and handle over 150k searches daily. we use shard keys to identify the appropriate server and route reads and writes accordingly. the routing is handled at the application layer.

People who love MongoDB either love it because it's the first database you're introduced to, or you're just running away from the cost of defining schemas. The irony is that while MongoDB may reward you with "schemaless" benefits when setting up, you still go ahead to define schemas in your code with Mongoose.. 🤔

you got 3 job offers one from Amazon one from the place you really want to work at one from the noname company paying you $470k base which one you pick?

I once worked with a senior backend engineer who believed that the strongest backend systems were the ones where logic is written more on the database layer than on the code layer. The normal if-else statement you would write to check a users balance, bro writes all that logic directly on the DB, there were triggers, database functions etc. Bro was literally coding with SQL. At that point I didn’t know SQL could even do all that. Bro would review my code then and ask me why was I writing all that logic in code when it could reside directly on the db😂. This was way before AI and bro would prefer to write every single thing by hand rather than install a package, he felt they were not secure. Bro uses a framework just to repurpose it and customize everything! At The point working with bro, he was almost 40. Man! I’ve worked with cracked devs, and I’m grateful for every experience that has shaped me.

The average Techie might not be able to afford Ai in the next 5years and it’s beyond sad

Sure. same problem with most people getting in the industry. Learn all the skills you want. You're still useless if you do not have a deep understanding of topics like: - Version control & team collaboration - Scale, system design, system architecture - Product engineering - Engineering cycles - Customer feedback to production software - Feature flagging & testing in production - Leadership, feedback giving and receiving - CI & CD pipelines, PR reviews - Analytical thinking, product management - Product strategy, user experience, communication And this does not even scratch the surface. And no. You can't learn this in 1 year.

Code mode improves MCP by allowing agents write code to invoke tools…but makes me wonder, maybe we should just ship SDKs instead of MCPs
