I would upvote this comment more if I could. I already refrained from introducing event sourcing to tackle wierd dependecies multiple time just by justaposing the amount of discipline that the team has that lead to the current state vs the

I don't agree with this cache take. Adding operations to the cache is easy. Taking the django-redis project as an example there are only two levels until you reach redis-py: The cache abstraction and the client abstraction.

The problem with channels is that if you need to touch the ORM you will have to use a sync_to_async call which will block the event loop.

Scale articles are too focused on architecture. What about business problems that come with scale. At a certain scale rare events are common many cases cease to be fixable by some random process that involves humans you have to handle a lot

AWS can make major version upgrades automatically now with less downtime. I think they do the logical replication dance internally.

In my experience PMs often work at a very high level. How things shold work are defined in a incosistent way when we take into account all the user flows, subtelness and restrictions of other systems. So programmers end up doing a significa

I will believe this theory if someone shows me that the ratio of scientists to engineers of leading teams of the leading companies deploying AI products is bigger than 1.

The author keeps aluding to the problem of loss of type inference without giving any example. I have no idea if the problem is relevant or not.

Are you refering to DRF model serializers? For medium to big applications I think they are worthless.

It's not FUD. For all the trouble you claim to have with Postgres I experienced 0 of it in the last 4 years. The only thing extra for a simple setup is a couple of lines in your docker compose files which is completely amortised becaus

This is a cool example but I think it is missing the perspective of what the interface can abstract. For example if I program a data structure to provide an Iterator I get to use these itertool functions for free no matter how complex the d

Java supports it? Are you conflating method overload (which is statically determined) with multimethods?

I'm looking at our Datadog stats right now. It is 64% cpu 36% IO.

Doesn't this depend on the number of servers, crash rates and recovery times? I wouldn't feel confident running 3 servers running at 80% capacity in ultra low latency scenarios. A single crash would overwhelm the other 2 servers i

This is using docker-compose. The old deprecated python standalone tool. Doctor compose v2 is a plug-in written in go for the docker cli. Edit: looks like Docker release docker-compose v2 as a go standalone tool ( https://docs.doc

Very nice discussion. A lot of times I see people assuming that Web Apps are IO bound anyway to justify technical decisions. Nevertheless here am I looking at our stats: 60% is python, 40% is IO and Postgres is getting faster than Python at

Well my experience has always been the opposite. New query patterns are always appearing. The difference between an OLTP and an OLAP query is not as clear cut as one might imagine that justifies huge changes to an existing system.

I don't read all the lines of code but I open and scan a ton of files from the code base to get a feel of which concepts abstractions and tricks are used.
