Code review antipatterns
Code review seems like a great idea, right? Two developers looking at the same code means two chances to spot problems; it spreads understanding of the way the project is evolving; the reviewer can learn useful tricks from reading the author’s code in detail, or spot opportunities to teach the author a useful trick…

Sourcegraph went dark
Towards the end of my mid-2019 job search, I was down to joining the Google Go team or Sourcegraph. Sourcegraph ultimately won due to cultural factors - the most important of which was the ability to build 100% in the open . All documents were public by default. Technical and product RFCs (and later PR/FAQs) were…
