At 42Floors, we experienced a similar need for auditing. Initial we did a
similar approach as described in the post. Over time the audit tables began
to be incorporated into every aspect of the product, which over time caused the
table to become quite large, and ended up causing a lot of downtime. Our initial
implementation only audited what was inserted by our Rails application. If a
change was made by another application or manually, it wouldn’t appear in the
table.
Over the course of a few months we extracted the system and built a standalone application that today has become [changebase.io](https://changebase.io/). We now use CDC, change data capture, to capture all events in the database and a metadata table to capture the context of why the change occurred and who made the change. The changes are then structured to be easily queryable.
Initially, we encoded the data as JSON, but over time have opted for encoding the data in the database’s native format. This creates a more complex query system, but at the end of the day we don’t have to worry about type conversions and querying is done in the same format the database that was replicated. Teams have benefited from the system by being able to recover data that was accidentally deleted, or deleted maliciously. Notifications have also been used for high value datasets where someone on a sales team wants to immediately know of a change in the system.

Strange that it would cost just less than a full tank of gas. I was assuming it would be much cheaper, not comparable to gas.

My guess is that this was just an easier story to sell because they can just approve accredited investors and not have to deal with those who are not due to regulations. They may have planned to make it open to everyone but had to step the plan back a bit.

Facebook users generally don't intend to transact though.

People did not criticize the post but the person.

It is a shame to see such hate against people. @antirez was attacked for openly sharing his thoughts about sexism. The sad part is that those who attacked him seek respect for their points of view yet do not give it to others.

This is an emotional article full of personal attacks and not worthy of reading.

Misleading title.

I'm not that great of a writer. My papers were usually in the B range and I almost never got an A. Then I started using LaTeX and now my papers are used as examples in classes.

Inflation isn't an increase in demand that leads to higher cost. Inflation is a general increase in supply. A rise in prices is not the same as inflation. Inflation will eventually cause a rise in prices but it is not the only reason for an increase in prices.
