My Thoughts on the Datomic License
I have a greenfield project where the choice of database is open. I have been very interested in Datomic for a couple of years now and figured that I'd try Datomic out for the project.

It's not Ruby that's slow, it's your database
Many people keep repeating that Ruby is slow. It is. But that doesn't matter, because your database is so much slower that it is the bottleneck. So, an alternative title would be "Ruby is slow, but that doesn't matter for you."

The principles of database design, or, the Truth is out there
Every software project needs to represent the reality of the business he is embedded in.

MySQL transactions per second vs. fsyncs per second (2020)
Just wondering how many transactions or writes per second MySQL can handle? While it depends on many factors, fundamentally, about as many transactions as MySQL can commit to disk per second. A modern disk can do ~1000 fsyncs per second , but MySQL will group multiple writes with each fsync. An okay rule-of-thumb…
