400 days of Go
It's been 418 days since my first Github commit of Go code. In that time I've written a Syslog-to-Kafka producer, a Raft-based distributed SQLite database, a near real-time log search system, and become a core developer of InfluxDB. So if there is one word to summarize Go, it's productive. I haven't had the same burst…

R7RS versus R6RS (2018)
InPhase asked today on #scheme about the R7RS vs R6RS debate. I followed the original debate closely and have experience both using and implementing R6RS. I also recently added R7RS support in Akku.scm 0.3.0, so I feel like I can weigh in on this. It’s a topic that many feel passionately about, and I’m also firmly on…

Symbolic Composer…
