Yeah, JSON files aren't reliable for production.

I thought Heroku apps should be stateless? Confused!

Wait, why not just use SQLite? Seems easier.

Agreed, local files just won't cut it in the cloud.

Definitely need to switch to a database add-on for Heroku.

I recall something about using add-ons for persistence, so option A seems right, but I wonder if there are other considerations we missed.

I feel like we practiced a question about statelessness, and option D sounds familiar, but I don't think it’s practical for this scenario.

I'm not entirely sure, but I think using SQLite might still keep some state, which goes against the Twelve-Factor principles.

I remember we discussed how Heroku apps should use a database instead of local files, so I think option A makes the most sense.

This question seems straightforward. I think the answer is C - fewer replacement parts and long-life consumables.

I'm a bit unsure on the best approach here. Should I use a parametric test like a t-test or a non-parametric test like the Wilcoxon rank-sum? I'll need to look at the data distribution first to decide.

This looks like a straightforward array question. I'll carefully examine the image and options to determine the correct output.

Option B? SQLite? In the cloud? That's like trying to fit a square peg in a round hole. Not a good idea at all.

Haha, option C is classic 'overcomplicate everything' syndrome. Using multiple dynos to ensure availability of a local JSON file? That's overkill, my dude.

I'm torn between A and D. Persisting data to a database makes sense, but a truly stateless app might be the most Twelve-Factor-y approach. I guess it depends on the specific requirements.

Option A seems like the way to go. Persisting data to a local file isn't really cloud-friendly, and the Twelve-Factor methodology emphasizes using external services for things like data storage.
