is the remaining difference between SQL and NOSQL boils down to APIs? want relaxed schema? BSON want eventual consistency/availability? logical replication if we built a RESP or Mongo API out of the box on Postgres will that increase Postgres adaptability even more?

watch out when indexing variable length columns in SQL Server. Just ran into the index key limit in SQL Server where it can’t exceed 1,700 bytes (non clustered, 900 for clustered). If the inserted/updated row has value for that field exceeding 1,700 the query fails

@hnasr Allegro works great usually. Sometimes I feel like my computer is directly connected to their server. And no, it’s not cached data. There was a slow down couple of years ago when they switched from a simpler to a complex system I think but it didn’t take long to get back.
The way this man explains everything in absolutely amazing man. ✨️ Loved your content man @hnasr 🍻❤️
@PR0GRAMMERHUM0R I love to watch @hnasr analyze and explain articles and news from big tech companies.
@hnasr Awesome, i need to finish your other two courses first (backend and database), then coming to this.
@hnasr I have to say this. The way you explain the concept is very straightforward and easy to follow which is the sign of true expertise. It's like someone did research for you and gave you the idea, so you don't have to do it on your own.
@hnasr I think the main difference is that the NoSQL APIs is limited to calls declaring all read/write intents from the beginning of the transaction. SQL can have in-transaction procedural logic, in the app or in stored procedures, triggers, also useful for secondary indexes, mviews...
@hnasr Still 2 year old are easier to handle than A small young team handling kafka and debugging it 🥹
@hnasr It's refreshing to see an instructor pay so much attention and care after their students and the questions. Thank you for continuing to push out great and useful content!
@hnasr Amazing course! I am going through it right now
Just kicked off my journey into the Fundamentals of Operating Systems with @hnasr! Excited to dive deep into the core concepts and mechanics that make our digital world tick. Let's navigate through processes, memory management, and more! #OperatingSystems #TechEd
Bro just shared his 183 pages notes on "Fundamentals of Backend Engineering" by @hnasr I'm not pasting the link here, best to go to the source to see the doc since it's not mine. Original source: linkedin.com/posts/activity… (must be logged in) The course: udemy.com/course/fundame…
Yes, so I originally started with the aim of explaining the internals of the JIT compiler but realized I need to explain everything which happens before it. So, there is a compiler which generates the tier-1 bytecode. And it is executed by the main interpreter. But this…
@abhi9u bytecode interpreter is explicit. virtual machine is ambiguous. I’m also wondering what part takes my raw python code to bytocode, I am assuming this happens outside the bytecode interpreter. would be nice to mention that. looking forward to the blog
A big appeal of the Turbo C period was that the internet was barely a thing. There was very little distraction and it was easy to get 'into the zone'. How do you deal with all the distractions? Impossible to work without the internet these days.
@sarah_edo "Everything that is, you are it" Read it from some philosopher when I was at university. Reminds me that there I am not separate from the world. I am in the world and part of it, and the world is a part of me. Very useful when life feels meaningless.
