Back in MeasureCamp Sydney I had the opportunity to reflect on lessons I picked up throughout my tenure as a data scientist at Atlassian. This led to a fun discussion at the APH on what it actually means to "get things right" in data analysis.

Major oopsies happen when data looks too good to be true...but we ignore our gut feeling. @arikf.net shared his hard-learned lesson about trusting intuition alongside rigorous analysis on the latest Analytics Power Hour! analyticshour.io/2026/04/28/2...

Oh, that's mean! 🤔

when i think about all the important moments in my life, and try to guess which will flash before my eyes at the end, my best guess is that it will be kurtosis🤔

I was tagged the other day by someone kindly sharing my Python Rgonomics post and realized that my thesis of "tooling keeps improving" held up too well and some of the recos have changed Hence, here's the 2025 update: www.emilyriederer.com/post/py-rgo-... Now feat uv (vs pyenv, pdm) and Positron

Switching languages is about switching mindsets - not just syntax. New developments in python data science toolings, like polars and seaborn’s object interface, can capture the ‘feel’ that converts fr...

Clio: Privacy-preserving insights into real-world AI use

Spent hours yesterday to get a SQL cell in a databricks job use a variable that was set in a prior python cell. Amazing how something that seems so trivial can be so convoluted. Is that what "business impact" looks like?

How did I just find this? wiki.postgresql.org/wiki/Don%27t... #databs

Great stuff, and an excuse to recommend the book Storytelling with Data by Cole Nussbaumer Knaflic for anyone who wants to learn more on this.

Trying something new: A 🧵 on a topic I find many students struggle with: "why do their 📊 look more professional than my 📊?" It's *lots* of tiny decisions that aren't the defaults in many libraries, so let's break down 1 simple graph by @jburnmurdoch.bsky.social 🔗 www.ft.com/content/73a1...

One of my favourite pieces on the role of the data analyst comes from @rdpeng.org , who in turn quotes Tukey's "The Future of Data Analysis" from 1962 (!) simplystatistics.org/posts/2019-0... #databs

In your view, what is the "problem" that a data analyst solves for an org?

one of the many things to like about atproto is that everything is authenticated and public you don't have to trust bluesky, you can read from the relay yourself it's not an API... more like a spinal tap into the central feed and this is an amazing example of what you can do with that power

A number of artists and creators have made their home on Bluesky, and we hear their concerns with other platforms training on their data. We do not use any of your content to train generative AI, and have no intention of doing so.

This is probably the one of the clearest explanations I’ve seen of zero-shot, etc arxiv.org/abs/2309.024...

I feel like this site's demographics can be described as "still mad about the loss of Google Reader"

I noticed my app habits changed over the last couple of weeks. I now head to bluesky for #dataBS, and head to X when I want to see temu ads.

This is a fantastic read. But depressing, but fantastic. hellooperator.substack.com/p/what-it-me...

What It Means to Be Data-Driven

Stop hiding behind the numbers and start using them instead.

Yeah, I think the immune response of "AI will replace us" was just so misguided. "AI will help us" is so much healthier. I write more code because of Cursor, not less.

I forgot to hashtag my #dataBS. Apparently this site doesn't have an edit button.

My takeaway: LLMs are risky for generating code unless: (a) it's simple enough to review quickly, (b) the output is easy to verify, or (c) mistakes are low-stakes and tolerable.

The talk about "automating analysts' work" reminded me of my past attempt to run an LLM through our Data Science Interview. medium.com/atlassiandat... A colleague of mine actually repeated that recently - it's clear that LLMs got better, but they still need a human in the loop to help them along.

Will Generative AI make data scientists obsolete?

Hi, I'm Arik. I'm a data scientist at Atlassian, living in Sydney, Australia. I did some software engineering and product management in the past, but a PhD on Privacy Preserving Data Mining eventually led me to work with data.
