Spent some time looking into software teams' effectiveness, and how software teams can use data to reflect and improve how they work. These days I'm trying to learn more about Statistical Process Control.

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.
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🤔

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?

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

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 (!)

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.

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.
