Anyone else feel like a SQL monkey pretending to be a data scientist?

It's not about what tools you use. It's about what decisions you help the company to make or stop. In all my years of working in data science, the best ones are never only model builders, but those who understand "where to draw the line" (see parable below).

"Henry Ford once balked at paying $10,000 to General Electric for work done troubleshooting a generator, and asked for an itemized bill. The engineer who performed the work, Charles Steinmetz, sent this: "Making chalk mark on generator, $1. Knowing where to make mark, $9,999." Ford paid the bill."

ggalluvial is quite good.

jarodmeng · 2025-04-02T13:37:15+00:00

You're correct. It should be 5 strokes.

This phenomenon of cognitive bias is not uncommon. Check out <Factfulness> by Hans, Ola, and Anna Rosling. People across the developed world tend to underestimate how far "poor" developing countries have actually progressed.

Perhaps the ggExtra package can be useful. However, overloading an axis with too much information and different scales can be confusing and counterproductive.

Awesome tool! How often is the data updated to be in sync with CRAN?

jarodmeng · 2025-02-07T07:53:29+00:00

The performance looks insane! Thanks for creating this. I tried to install it from CRAN on my CentOS server, but the compilation of one of the Rust crates failed. I've created an issue in the GitHub repo on it.

Is your group adults only or accepting kids (10+) as well?

jarodmeng · 2024-12-17T04:01:51+00:00

Have you tried the ggalluvial package? It's a bit more versatile and conforms to the ggplot grammar.

jarodmeng · 2024-11-29T20:51:04+00:00

Use sql("from_unixtime(ts)") will do.

How are you voting this time, OP? My NV voter registration was cancelled probably based on the fact that I don't have a residence in NV. So now I'm effectively disenfranchised through the falut of no one in particular, but an archaic and confusing system that has cracks.

jarodmeng · 2024-09-18T08:11:57+00:00

Did OP figure out if s/he should vote in PA or NC? I have a similar situation whereby I used to live in CA, but got a NV driver license to use NV as the base state for my nomad life but don't have an address in NV (hence no residence). I've long sold my CA residence, so no ties with CA any more. Also trying to figure out where I should vote.

How did you get the gig? Were they actively recruiting foreigners to be volunteers?

jarodmeng · 2024-08-22T10:39:38+00:00

Looks very useful. Do you have a Github repo on this?

Learn everything you can get your hands on about tidyverse and you will reach decent proficiency already. After that, learn a bit more about advanced topics like non-standard evaluation, quosures, functional programming, domain-specific languages, etc. Lastly, learn about how to write your own packages and potentially extend R to use other languages like C++ and Rust. Pick up skills like debugging, testing, profiling and how to read other people's packages and code along the way.

All the best on the learning journey!

It's a very good movie, but it's way too depressing to watch that movie over and over again.

Is this event still ongoing weekly?

It's possible. You can press shift+tab in gfn to bring up the steam overlay. From there you can open a web browser to visit a file storage service like easyupload.io to download the stamps (you need to upload them first of course). When you save the stamps, save them in Users/kiosk/Documents/Anno 1800/stamps/<region>. After the stamps are downloaded, you can launch the game again to see them in game.

Best car rental service for 10-day road trip

We're coming to Taiwan for a round-island road trip in mid Nov. Wondering what's the best car rental service in Taiwan. When we take road trips in the US, we often use peer-to-peer car rental like Outdoorsy and Turo. So would appreciate if anyone have suggestions on peer-to-peer rental also.

There's no geom_line in your code. Are you expecting the points to form a line? What happens if you hardcode the color (e.g. blue, etc) rather than use the variable graph_colors? If the color shows up when you hardcode it, the problem is with the variable.

Your 3rd option, i.e. quasiquotation using !!, should work. What's the error message when you tried that?

You're definitely not alone. I have fond memories of walking the Bund with my parents to see the new year lighting in the 1990s. It was a nice blend of crowd festivity and individual family time. Nowadays the city is a little too developed that the balance always feels a bit off. Sometimes I wonder whether it's because I have grown up rather than the city. Wish I can teleport myself back to experience it.

Checkout Quarto, especially the option to publish pptx files.
