1. Can LLMs write better code if you keep asking them to “write better code”?
Total comment counts : 63
Summary
The article discusses a trend where users of ChatGPT, after integrating DALL-E 3 for image generation, engaged in a meme where they iteratively modified images to become more extreme versions of a given attribute (e.g., making Santa Claus more serious). This trend, although short-lived and considered “AI slop,” showed an interesting convergence in the images towards something cosmic regardless of the initial prompt.
The author then pivots to explore a similar concept with coding, questioning whether iteratively prompting an AI like Claude 3.5 Sonnet to “make the code better” could enhance productivity. They conduct an experiment using a simple coding task in Python, asking the AI to optimize the code iteratively. Initially, the code provided by Claude is functional but basic, typical of a novice programmer. Upon iterative prompting for optimization, Claude refactors the code into a more object-oriented structure and makes algorithmic improvements, significantly enhancing performance by 2.7 times compared to the initial version.
The article highlights the potential productivity benefits of such AI-assisted coding practices while also touching on the distractions and costs associated with using AI tools for coding. The author expresses skepticism about AI coding assistants but acknowledges the impressive capabilities of newer models like Claude 3.5 Sonnet in adhering to complex coding prompts and optimizing code effectively.

The article discusses an optimization for code that checks if a number falls outside a given range before performing a digit sum operation. Here are the key points:
Optimization Suggestion: The author points out that a simple optimization was missed both by an LLM (Language Learning Model) and the original code’s author. This optimization involves checking if a number is less than the minimum or greater than the maximum before calculating the sum of its digits. This check can significantly speed up the process.
Performance Impact: On an M1 MacBook Pro, using NumPy for random number generation and mod/div for digit sum:
- The base version of the code took 55ms to execute.
- Implementing the range check before digit sum reduced execution time to 7-10ms, which is nearly as fast as a more complex optimization involving Numba (a just-in-time compiler for Python).
Comparison with Numba: Using Numba actually slowed down the process unless extensive pre-calculation of digit sums was performed, which was deemed inefficient.
Observation on LLMs: The author notes that LLMs are less effective at identifying significant algorithmic or big-O improvements compared to other coding tasks, based on personal experience.
In summary, a straightforward logical check before performing a more complex operation can lead to substantial performance improvements, often making more sophisticated optimizations unnecessary.

The article discusses the author’s experience with using an AI model, specifically mentioning issues with initial mediocre or incorrect responses, particularly with more obscure tasks like OpenSCAD coding. The author has developed two strategies to improve the AI’s performance:
Direct Request for Quality: The author instructs the AI to skip the initial mediocre attempts and provide a high-quality solution right away.
Negative Incentives: Out of frustration, the author employs a strategy of threatening the AI, not directly but by warning of severe consequences for OpenAI (the company behind the AI) like lawsuits and imprisonment of board members if the AI provides incorrect information. This approach seems to yield better results, possibly due to triggering some form of risk-averse behavior or alignment protocols within the AI’s programming.

The article discusses the “type=history” mode in a data streaming tool called Streamer by Kuvasz, which automatically constructs a Slowly Changing Dimension Type 2 (SCD Type 2). This mode is useful for managing historical data changes:
Functionality: The mode helps in creating an SCD Type 2 which tracks changes over time by inserting new records for each change rather than updating existing ones.
Issues with Implementation: However, the author points out that the current implementation has flaws, particularly in handling multiple updates within the same day, leading to potential date overlap issues in SQL queries which could result in duplicate records.
Suggested Improvements:
- A) Update the end date of the previous row to the day before the change rather than the current day.
- B) For records that begin and end on the same day, use NULL or a very old/future date for either the start or end date to prevent these records from appearing in typical date-based joins, yet still maintain an audit trail.
These improvements would ensure that queries return only one relevant record for each date, avoiding duplicates and maintaining data integrity.
