@theburningmonk I wonder why AWS can skip the eventual consistency check when creating resources but MUST be consistent to when reporting a CREATE_COMPLETE.

Perhaps it's so that AWS can be sure that the CLI/SDKs will always see the created resources after the stack reports CREATE_COMPLETE.

This new CFN feature sounds incredible! Hopefully, it can now compete with Terraform. https://t.co/8ZzNIppcOW

I suspect this is the feature that caused this bug. 🐜

[Dale Salter @enepture]

It's wild that there has been an S3 / CFN bug causing stack creation failures around 5% of the time for > 60 days. It blows my mind how this was not picked up during some kind of internal testing. ESPECIALLY given how big both of these services are. https://t.co/P6fWam7uS6

@tsoding What’s a pointer

[Dale Salter @enepture]

Ever wondered how isolation levels work? How transactions are implemented?

I’ve spent the last few months going deep and @andy_pavlo’s CMU course is very approachable and is the best of the best. Also what’s even better is it’s free. https://t.co/y4ytVSfAQO

@petehanssens Rust solves a similar set of problems as C++, operating systems, drivers, UI, games etc. Excluding some games companies Australia does not write any software that needs this level of optimisation.

I was thinking that if you submit an entire transaction in 'one go' it would be treated as a statement. Though as far as pg/pgbouncer is concerned it doesn't matter if it's in 'one go', if it's go a BEGIN; pgboncer will drop the whole connection.

[Dale Salter @enepture]

Hey @jpcamara -- enjoyed your article. https://t.co/wfjJQEpnU1.

Question -- if you submit a transaction as a single query, e.g. the `BEGIN; statements; COMMIT`; in one go, can you still use statement pooling?

@ckarmstrong Seems like Australia is slowly heading towards the Chinese housing market 💣

@bulkanevcimen @petehanssens 3/ I know you didn’t ask, but I’ll share anyway. Where I’m starting is building a redis cone, one thread for the database, a thread per connection, and then MPSC channels for sending the request to the DB and a one shot channel for sending the response back.

[Dale Salter @enepture]

@bulkanevcimen @petehanssens 2/ If you really want to flex the language building very simple MVCC database a great learning experience. You get, file serialisation, networking, concurrency primaries, memory synchronisation, threading, networking, some mutability.

[Dale Salter @enepture]

@petehanssens Like cargo 😂? Been using python a lot recently, I’m starting to understand its appeal. It’s nice not needing to write await everywhere.

[Dale Salter @enepture]

@bulkanevcimen @petehanssens I was thinking of the same, though, ended up getting carried away on side projects. I love me some result / optional type, so good.

[Dale Salter @enepture]

@AWSbrett I think if you define an exports name the key will be static

[Brett Andrews @brettandrewsai]

@benjamenpyle Ahh. Dale Salter at @VendiaHQ dealt with some challenges there https://t.co/lfPsDkqQh6

Decorators don’t belong in JS

Don’t @ me (because that’s a decorator)
