Logistics this week & agenda

• Cue-to-Cue assignment open
• Due to some drops, 1 team got re-distributed
• Customer intros happening today! Yay!
• 4-unit petition—reminder
• 2-minute mindfulness
• Today: live demo of Cue-to-Cue Dryrun assignment

2-minute mindfulness

• All devices in “do not disturb” (not silent) / quit apps so no stimulus/interruptions
• Chat will be off, everyone muted
• Start with 3 very deep breaths…

​

Goal: focus on 1 thing for 3 minutes.�Breathe normally.�If you get distracted, just acknowledge that, let go, and begin again.

Counting breaths may help.

Why?

• Training your mind to focus on the here & now measurably improves performance on high-concentration tasks
• In experiments with software engineering...
• Mindfulness group: 10 mins, 4x/week for 4 weeks
• Control: public speaking, same amount
• Treatment group had higher semantic expressiveness (i.e. capturing requirements clearly & completely in UML diagrams)
• …and higher efficiency (SemEx / time)
• We will post the paper(s) in bCourses

Cue-to-cue: live demo afterthoughts

• Close team communication is key
• Slack integration or other way to keep up
• short-lived branches!
• Propose merge to “golden repo” as soon as each feature merge is “clean”
• Consider setting up multiple staging apps
• Heroku pipelines allow an app per branch
• keeps “main” deploy clean for customer use
• Many other “SWE-as-a-service” solutions…
• CI: GitHub Actions, Heroku CI, Jenkins, Circle
• Code quality/coverage: Hound, CodeCov, Coveralls
• Project boards: GitHub Projects, Trello, Basecamp

Range and other Slack integrations

• GitHub
• TravisCI
• Heroku

What happens next

• Cue-to-cue is easy but not brainless
• Tracker (use your @b.e email)
• Customer intros
• Slack channels—you can then setup any integrations
