msk20 | 3 years ago | on: Ask HN: How are pull requests integrated in a repo with high commit frequency?

There is ZUUL Gating[0] CI it is actually the perfect solution for this. It works with Github or Git based repository system.

It automatically tests the changes with a simulated merge on master together. So it orders PR1 -> PR2 -> PR3 -> .... -> PR-100 by order of approval. If PR1 -> PR2 (Fails) -> PR3 -> .... -> PR-100

It restarts -> PR3 -> .... -> PR-100 and Up after removing PR2. This behavior is even customizable.

Video of it in action: https://zuul-ci.org/media/simulation.webm

msk20 | 4 years ago | on: Ask HN: How would you store 10PB of data for your startup today?

I don't really know much about optimizing storage costs, But You could learn from storage giants.

Example is Blackblaze storage pod 6.0 according to them it holds 0.5PB with a cost of 10k$, you will need about 20*10K$ = 200K$ + Maintenance(They also publish failure rates) , The schematics and everything is in their website and according to them they have already a supplier who provides them with such devices which you could probably buy from. Note: This was published 2016, they probably have Pod 7.0 by now so cost may be better.
