As G10 countries succumb to simplistic populism, reckless fiscal policy and fiscal dominance of their central banks, the line between the G10 and EM is getting blurred. Real long-term interest rates in the G10 have begun to rise towards EM levels...

Happy to know I'm not the only one who creates a ggplot2 theme package for every company I work with #positconf.

Not only does it standardize communication, but it also makes a great impression. theme_quintoandar() took about a day to make and led to me reporting directly to the C-level.

One strategy I'm using is to ask ClaudeCode to write a small summary of what it's done + add context for future work when it's almost done with a task. I then use /clear, ask Claude to read the document, and give it instructions on the next task.

4. Avoid auto-compacting

The last point is directly tied to this one. ClaudeCode has a context limit (the UI warns when approaching this limit) and it auto-compacts by default. The quality of compacting can sometimes be unreliable and I found it best to just workaround it.

You can ask for ClaudeCode to take notes of useful information and store it in separate md files to help build this knowledge.

A great example of useful context to provide Claude with (from @sarahjohnson.io) gist.github.com/sj-io/3828d6...

3. Knowledge

Anthropic recommends that you create a CLAUDE.md file to store important context. Currently, I'm experimenting with an entire claude/ directory stashed with useful content. Before starting a new task I ask Claude to read the relevant content.

Ex: I asked ClaudeCode to download an Excel file, import it in R, and make it tidy. The download, however, failed due to network issues and Claude decided to invent a dataset with fake values instead of stopping and pointing this error.

2. Manually approve

While ClaudeCode seems magical when it "just works" it often doesn't. Auto-accept can lead to errors that hard to detect since Claude can sometimes omit them and say that everything worked according to plan.

1. Make plans

Always start a new task in plan mode and invest some time making sure that Claude has a solid plan. A neat tip from Anthropic is to use "think more...", "think hard about potential issues...", "think step by step ... ".

"think" < "think hard" < "think harder" < "ultrathink."

Been working with ClaudeCode for the past ~2 months (mainly R and Quarto). My main tips:

1. Plan a lot.
2. Manually approve (auto-accept only for very simple tasks).
3. Create knowledge that can be referenced.
4. Avoid /compact and auto-compacting.

I've been using Air since switching to Positron and have been loving it. My only criticism is the styling of tibbles (it just breaks them). Apparently that has been solved

The fastest way to start using & exploring the new 2024 1-year ACS data?

R with tidycensus + mapgl.

With just a few lines of code, you can pull down any of the thousands of variables available in the new data and explore on an interactive MapLibre map.

I was loving Claude Code... until I tried it with #rstats. Constant errors, wouldn't use the tidyverse even when asked, "optimized" functions were slower.

Frustrated, I started a session just to teach R to Claude and summarize what it learned into a CLAUDE.md file gist.github.com/sj-io/3828d6...

Saw a post from an influencer telling followers to "stop using R for anything -- use Python like a normal person"

As a 10+ year R & Python user, the irony is that 2025 is the best time EVER to be using R.

Here's why:

Worst of all, since the numbers were generated with *data* they were heralded as an objective fact of the universe.

What a great piece on online advertising. Summarizes beautifully my frustrations when working as a data scientist (with econ background) in a big marketing department.

Leaders justified decisions with bad metrics, fueled by biased samples.

I do plan on splitting up my site. I think it's a bit too all over the place, and I find myself second-guessing whether I should write in Portuguese or English, whether I should break down my analysis in a tutorial or just present it as is, whether I should show the code or hide it, etc. etc.
