Shocking how far ahead Claude Code is from Codex on the CLI front.

With Claude Code I created an agent that spawns 5 copies of itself branching git worktrees from main branch using subagents so no context leaks into their instructions. The agent will every 60 seconds analyze the performance of each of the copies which run for about 40 minutes answering the question "what would you do different?". After they finish the task, the parent will update the .claude/ files enhancing itself…

Where is 263 GB database of every stock quote and options trade in the past 4 years?

I think this is the argument for UIs - it should be self-explanatory since it's singificantly simpler than an IDE

> I think this is the argument for UIs

To quote The Godfather II, "This is the business we have chosen."

The most popular and important command line tools for developers don't have the consistency that Claude Code's command line interface does. One reason Claude Code became so popular is because it worked in the terminal, where many developers spend most of their time. But using tools like Claude Code's CLI is a daily occurrence for many developers. Some IDE's can be just as difficult to use.

For people who don’t use the terminal, Claude Code is available in the Claude desktop app, web browsers and mobile phones. There are trade-offs, but to Anthropic’s credit, they provide these options.

I use TimescaleDB which is fast with the compression. People say there are better but I don’t think I can fit another year of data on my disk drive either or

Options quotes alone for US equities (or things that trades as such, like ADS/ADR) represent 40 Gbit per second during options trading hours. There are more than 60 million trades (not quotes, only trades) per day. As the stock market is opened approx 250 days per year (a bit more), that's more than 60 billion actual options trades in 4 years. If we're talking about quotation for options, you can add several orders of magnitude to these numbers.

And I only mentioned options. How do you store "every stock quote and options trade in the past 4 years" in 263 GB!?

I think this would be pretty straightforward for Parquet with ZSTD compression and some smart ordering/partitioning strategies.
