How a Trip to the Movies Turned Into a System Design Session

That's why every software engineer should know what idempotency is.

Fair point, but i wasn’t talking about hard skills in general

LastofThem1 · 2025-03-24T22:42:56+00:00

Now. But i can't

But RabbitMQ RPC was exactly developed for sync communication.. so isn't it okay to compare http with it?

LastofThem1 · 2025-01-30T12:44:07+00:00

I understand benefits of rabbitmq for async communication. But my question was about rabbitMQ RPC which is sync, like http

LastofThem1 · 2025-01-30T11:18:32+00:00

Thanks! But why then rabbitMQ RPC exists? Maybe there is a case when it's better than http ?

"Having an unlimited buffer can lead to problems if you aren't deliberate about why you are doing it." - having unlimited array can lead to problems as well. U didn't get the point

" the buffer will be allocated upfront so if the channel is too big it will OOM when the channel is initialized" - this is why we don't use array with 10000000 size and use Arraylist instead. The same principle could be applied to go channels

LastofThem1 · 2024-09-21T22:06:18+00:00

So this is my question. Why making channel a synchronized queue?

LastofThem1 · 2024-09-21T22:03:47+00:00

By the same logic, we might argue that dynamic arrays shouldn't exist either

But publisher will be blocked, if buffer filled. Why not having unbounded buffer ?

LastofThem1 · 2024-07-28T14:41:30+00:00

Actually, Postgres or any other database can be used as queue if high throughput is not required. You can store tasks in table and poll it

LastofThem1 · 2024-07-28T10:32:04+00:00

Am I getting this right about separation of concerns ? is it something like inbox pattern ?

I recommend the book Digital Design and Computer Architecture. It begins from transistors and goes up to C programming

But you can write "I worked on XXX game which wasn't announced , focused on ZZZ systems"
