Weekly Notes and Discoveries | S Anand

Measuring developer productivity with the DX Core 4 is a framework for measuring developer productivity. It encapsulates other frameworks like DORA, SPACE, and DevEx. #ai-coding-tools #best-practices #dev #markdown

Wednesday comes from Wōdnesdæg - named after Odin (or Woden).

Cloudflare tunnel is like ngrok but more permanent. It's a bit more complex, too. But given CloudFlare's liberal free tier, it's a good, viable option for long-term local hosting. #cloud #hosting #networking

John Wheeler: "We live on an island surrounded by a sea of ignorance. As our island of knowledge grows, so does the shore of our ignorance." A great way to understand how ignorance actually grows as you learn more.

There is little reason to use Redis. There are several clones like Microsoft's Garnet or DragonFly (only Linux) that are better. Databases in 2024: A Year in Review

Every few years, something comes along trying to replace relational databases and SQL, and gets absorbed. YouTube #database
- Key value stores. People soon realize they need more features, e.g. indices.
- MapReduce systems. Most MapReduce vendors put SQL on top of SQL. Then the Hadoop market crashed. (But HDFS, S3, distributed storage systems are a good idea)
- Document Databases. JSON. SQL absorbed that. SQLite 3.45+ supports even JSONB. DuckDB, of course, has JSON.
- Column Databases. Again, these introduced SQL.
- Graph Databases. SQL:2023 introduced graph queries via SQL/PGQ (Property Graph Queries). DuckPGQ beats Neo4J
- Array Databases. SQL:2023 adds SQL/MDA which allows for matrix operations. But specialized databases might make sense in this category.
- Vector Databases. Every DB is adding support for this.

Can LLMs write better code if you keep asking them to “write better code”? A delightful exploration of how Claude 3.5 Sonnet keeps optimizing and adding features to improve code. My takeaway: repeatedly applying a prompt gives us interesting new directions to explore. #ai-coding-tools #code-agents #llm-ops #markdown #optimization #prompt-engineering

smolagents is a new agents library from HuggingFace. It seems simple enough to use. #code-agents #huggingface

whisper-flow does real-time speech transcription! #future #speech-to-text #tts #voice-cloning

Switchboard-1 is a labelled audio corpus with ~260 hours of speech. It has ~2,400 calls among 500+ speakers in the US. #speech-to-text #voice-cloning

Salvatore Sanfilippo (antirez - Redis) finds DeepSeek v3 comparable with Claude 3.5 Sonnet. YouTube #search
- He also passed a paper and his code to compare them. A useful prompt. YouTube
