The last few days I spent some time digging into the recently announced KIP-1150 ("Diskless Kafka"), as well AutoMQ’s Kafka fork, tightly integrating Apache Kafka and object storage, such as S3. …
So there are only 2 web browser engines, and it seems likely there will soon only be 1, and making a whole new web browser from the ground up is effectively impossible because the browsers vendors have weaponized web standards complexity against any newcomers. Maybe eventually someone will succeed and there will be 2…
How do you fit a dictionary in 64kb RAM? Unix engineers solved it with clever data structures and compression tricks. Here's the fascinating story behind it.
