Q: Does MongoDB support transactions?

A: MongoDB does not provide ACID transactions.

( http://docs.mongodb.org/manual/faq/fundamentals/#does-mongod... )

It is crazy to be doing financial stuff in a DB that doesn't provide transactions. It completely blows my mind that anybody would do this.

We know all financial companies use databases running on tandem or tuxedo. But that's not cool sounding. How are they supposed to get fun jobs doing nothing with catered lunches? HOW, HOW I ASK!

I've heard of somewhere like ADP using it but they are using it as an analytics database, not for actual payroll processing.

I feel bad for someone that can't put a finger on his 30K, but I can't feel that bad if he didn't do a little research here first.

Hopefully on the next bubble people will be a little more enlightened.

Now, it's possible that other complaints on HN were nuked by PG or some other moderator, making it difficult for someone to find it.

That's not why he said that. He explains further down thread:

HN is a news site, not a customer support forum for companies funded by YC, and in fact the site guidelines explicitly ask that it not be used that way

If you bothered to read the other thread, you'll see parallels to the current situation:

- transaction delays on the order of 1 week

- Coinbase is blaming technology (last time it was a database migration, this time server upgrades)

- Customer support has been silent (znowi described it as "information vacuum" https://news.ycombinator.com/item?id=5427985)

- Online account system called into question, users unaware of current positions (e.g. https://news.ycombinator.com/item?id=5428090)

If this were the first time, you can cut some slack if Coinbase responded appropriately and took steps to prevent this from happening in the future. Based on what played out recently, it's not clear if Coinbase actually learned anything from the previous issues.

And in the future, if you ever do decide to start a company and find yourself in a similar situation, I hope you would be a bit more communicative and proactive than Coinbase was in this case.

You said that the standard approach on HN is to silence criticism -- a stupefying statement, given that at the time you posted it, this conversation had maybe 100+ comments and had been on the front page for a while. Also, in that same comment, you linked to another voluminous thread criticizing Coinbase. Amazingly, the existence of your comment strongly mitigates against your thesis being true.

I think you must realize this at some level, as you have chosen to employ the age-old tactic of the inescapably wrong: quietly change subjects and hope nobody notices.

> Strictly speaking I should have killed the post entirely

And this was 9 months ago. We are left to assume that the policy was enforced (after all, if the post were killed, it wouldn't show up in a search).

And even in this thread: https://news.ycombinator.com/item?id=6931168

> I've been keeping my mouth shut here about Coinbase after starting that thread 9 months ago.

I wouldn't be surprised to hear others echo the same sentiment (concern about expressing grievances about Coinbase) especially after PG's responses in the original conversation.

Others in the original thread refuted the argument you are presenting, so I recommend you start https://news.ycombinator.com/item?id=5428757 before rehashing arguments that have already been addressed

Given that many defenders of coinbase, including PG, are seeing support requests as criticisms, (threads that criticize coinbase = threads that seem like support requests) in their heads.

Therefore, (pointing to the statement that HN is not a support forum) + (commenting that PG should have killed the thread) = (PG is likely to kill all threads that may seem like support requests) = (PG is likely to kill all threads that criticize coinbase)
