The 19 Pandas functions you need to memorize
Long time readers at the Sharp Sight blog will know the emphasis I place on data manipulation. You've heard me repeat the statistic many times: 80% of your work as a data scientist will be data manipulation. Although it's a little more complicated than that, roughly...
Master the core, then expand
Last week, I wrote a blog post explaining that it's actually hard to master data science ultra fast. In order to master data science at an accelerated rate, you need to do a lot of things correctly. You need to work hard, and you need to do things that most students...
The hard way is the best way
Here at Sharp Sight, we teach data science. And in particular, we show people how to master data science extremely fast. Exceptional results, as fast as possible. Our training methodology borrows heavily from elite performers and "ultra learners," wherever we can find...
Why fluency matters
Here at Sharp Sight, I frequently use the word "fluent" to describe an ideal skill level with data science. When you join our courses, our goal is to help you become "fluent" in data science, or "fluent" in a particular skill. We want to help you become fluent in data...
Start Small, then Go Big
One of the common questions that I get from my readers is about "big data." This is particularly true of beginners, who frequently read or hear the term "big data," and think that it's extremely important, and that being able to work with big data is necessary for a...

How to create a beautiful map with R and geom_sf [part 2]
Last week in Mapping Texas Ports with R [part 1], we created a simple map of Texas ports with R, ggplot2, and geom_sf. That map was really just a "rough draft." It's not terrible, but it didn't look great either. This week, we're going to take that map and polish it...

Mapping Texas ports with R [part 1]
In the last few months since covid-19 has struck, everyone is suddenly talking about supply chains. Just a few months ago, this was sort of a "boring" topic, only discussed by import specialists and corporate operations managers. But now, here we are, wondering where...
Why I still love R
One of the most common questions I get from data science students is "should I learn R or Python?" In the last year or so, many of the blog posts at the Sharp Sight blog have been Python data science tutorials, and I've actually been using Python a lot myself. But...
