|
|
@joshvera:

|
|
|
|
@robrix:
|
|
|
|
- Alignment resolved!
|
|
- Getting diff summaries merged.
|
|
|
|
|
|
## What was challenging?
|
|
|
|
@joshvera:
|
|
|
|
- Didn't make as much progress on the structure of diff summaries as desired.
|
|
|
|
@rewinfrey:
|
|
|
|
- Continuing to adjust to the project.
|
|
- Hit an edge case in Minimax that is tricky.
|
|
|
|
@robrix:
|
|
|
|
- Not sure why the line approach in alignment solved the problem.
|
|
- In stack 1.1 you cannot rely on it rebuilding internal packages (must clean and rebuild semantic diff tool)
|
|
|
|
|
|
## What did you learn?
|
|
|
|
@joshvera:
|
|
|
|
- Learned about the different types of preludes.
|
|
- Learned about an extension in GHC 8.0 that introduces Applicative Do syntax, but is tricky to use in parallel computations because of the order of executation.
|
|
|
|
@rewinfrey:
|
|
|
|
- Learned about different recursion schemes (zygotmorphism
|
|
- The transition from thinking about function application to thinking about function composition was an eye-opener.
|
|
- Understanding a lot more about why certain shapes are advantageous.
|
|
- http://livestream.com/accounts/16500216/events/5467460 (first video)
|
|
- Greg Pfeil's talk: 02:24 Recursion Where FP Hits Bottom
|
|
- Amar Shah's talk: 04:24 Point Free or Die
|
|
- Ashley Powell's talk: 05:57 Negotiating Salary for Women in Tech
|
|
- Patrick Thomson's talk: 06:25 Bracer: Transforming Real-World Languages with Coproducts and Recursion Schemes
|
|
|
|
@robrix:
|
|
|
|
- Learned a lot about GHCi debugging.
|
|
- Remembered to question assumptions, specifically about alignment property tests that were throwing results off.
|
|
- Using Arbitrary for purposes other than QuickCheck.
|
|
