Hello! The teams are back from their trips to ZF Dev Summit and conferences in Sofia. Last arborist call already showed a lot of progress made on all fronts. Don’t miss it!

Kudos to Zaino and Zebra devs for squashing this annoying bug bug: Repeated error in TrustedChainSync when syncing coinbase spend that was affecting Zaino development!

Marek had been battling with Continuous Integration infrastructure that was slowing down Zebra development and the team announced those problems were solved. To those who don’t know, CI is crucial for development.It provides quick (but not instant) feedback to developers on how changes may have impacted the overall system. The downside is that CI is very difficult to deal with. Requires maintenance and when it breaks, it’s hard and slow to fix. Imagine that you had to troubleshoot a problem on your PC, but in this case you are not home, you call your house and someone does the steps you instructed and tell you what happened. That’s how working with cloud-based CI is. The advantages are HUGE but there are moments like these where the benefits are shadowed by the maintenance efforts.

The Zebra team is currently working on important things for Zaino and Block Explorer support.
