PR Your Own PRs: How to Slow Down and Improve Code Quality

reddit.com
Author: RGBrewskies
Date: Dec 07, 2024

Key Comment “For most developers, this ‘you’re going too fast’ really means ‘you’re solving the problem, but you’re stopping once it’s solved.’”

• Common mistakes:

  • Only handling the happy path, missing edge cases.
  • Lack of tests that catch those edge cases.
  • Poor code quality: unclear variable names, functions doing too much, lack of DRY principles.

• Solution:

  • “PR your own PRs. Thoroughly. Be a jerk to yourself.”
  • Imagine the toughest critic reviewing your code.
  • Review your PR at least three times:
    1. Before submission (for yourself).
    2. Immediately after submission (to avoid wasting your team’s time).
    3. After approval, before merging (to avoid 2 AM calls).

• Many engineers start in environments that prioritize speed over quality. As you advance, professionals emphasize clean code, tests, and quality.

• Quote: “If you want to go fast, go well” - Robert Martin, Clean Code.

Replies

• portra315: PRing your own PR is a major skill; leaving comments on your own PR clarifies decisions before others ask.
• catch_dot_dot_dot: Most devs don’t leave comments on their own PRs, but it’s incredibly useful.
• MrJohz: Start reviewing before writing code—think through edge cases, task purpose, and possible refactors first.
• danielt1263: “Never turn in your first draft.” Apply red-green-refactor—too many stop at “green” (just making it work).
• gyroda: Reviewing code in the PR UI instead of an IDE helps with context switching.
• randizz1e: Rushing prevents consideration of architecture and long-term maintainability. OP’s managers likely see the effects of this. Ask questions early to avoid costly refactors.
• Greedy-Grade232: PR YOUR OWN PRs should be in bold, caps, and large font. Leaving self-comments shows constructive thought.

Design Token-Based UI Architecture

martinfowler.com
Author: Andreas Kutschmann
Date: December 12, 2024

• Design Tokens as a Single Source of Truth

  • Tokens represent design decisions as structured data for consistency across platforms.
  • Automates updates and code generation using tools like Style Dictionary³¹ and Specify App³².

• Layered Architecture for Scalability

  • Option Tokens: Define base styles (e.g., color palettes, spacing).
  • Decision Tokens: Specify how styles are applied in different contexts.
  • Component Tokens: Determine where styles are applied in UI components.

• Automating Design Token Distribution

  • Version control with Git: Ensures traceability and synchronization across teams. Tokens Studio³³ supports bidirectional syncing.
  • Pipeline integration: Converts tokens into platform-specific formats (CSS, SCSS, XML) with Theo³⁴ and Diez³⁵.
  • CI/CD integration: Uses Style Dictionary³¹ to automate validation, testing, and publishing.
  • Testing & Documentation: Storybook³⁶ enables visual regression testing.

• Scope and Token Management

The Miyawaki Method: A Revolutionary Way to Grow Mini-Forests

youtube.com

• Miyawaki Forests Grow Faster & Denser: Trees grow 10x faster, are 30x denser, and 100x more biodiverse than conventional tree planting.
• Methodology:
  • Soil is carefully analyzed and prepared with organic fertilizers and mycorrhizal fungi.
  • Dense planting: 3–5 species per square meter vs. one tree per square meter in traditional methods.
  • Layered structure: Mimics natural forests—canopy, secondary trees, shrubs, and ground cover.
• Proven Benefits:
  • 99% survival rate (vs. 75% in conventional planting).
  • Twice the wildlife density and retains leaves longer into autumn.
  • Lower long-term costs due to high survival rates and minimal maintenance.
• Community Involvement: A core part of the method, making reforestation a shared, local effort.

Large Concept Models: Language Modeling in a Sentence Representation Space

vizuara.substack.com
Author: Siddhant Rai and Vizuara AI
Date: December 30, 2024

• Conceptual Shift: LCMs move away from token-level modeling (like GPT) to sentence-level processing, treating sentences as the atomic unit.
• Separation of Representation and Computation: Encoding (SONAR) and processing (LCM) are decoupled, allowing flexible operations in concept space.
• Bias and Manifold Learning:
  • Inductive bias can aid efficiency, robustness, and interpretability.
  • Instead of constraining data, LCMs apply structure to concept space movement (e.g., via diffusion models).
• Architecture:
  • Encoder (SONAR): Fixed character-level tokenizer maps input to embedding space.
  • Processing (LCM):
    • Base LCM: Simple transformer using MSE for embedding alignment.
    • Diffusion LCM: Predicts next sentence embedding via noise interpolation (One-Tower and Two-Tower variants).
    • Quantized LCM: Uses residual vector quantization to approximate embeddings.
  • Decoder: Converts sentence-level embeddings back into output modalities (text, speech, etc.).
• Key Findings:
  • Diffusion LCM outperforms other methods in paraphrasing and content generation.
  • Concept-level processing enables cross-lingual and multimodal generalization.
• Future Research:
  • Hierarchical LCMs for multi-level information processing.
  • Applying PEFT (Parameter Efficient Fine-tuning) for knowledge extension.
  • Testing fixed manifolds with known boundary conditions.
