Excited to launch the new improved Reproducible Code guide from @britishecologicalsociety.org @methodsinecoevol.bsky.social FREE online here! www.britishecologicalsociety.org//wp-content/... Amazing work by some very talented ECRs. We hope it’s useful!

Argh! @github.com announces it will start charging even for *self-hosted* runners 😥. resources.github.com/actions/2026... I have long relied on my self-hosted runners in my teaching to run automated 'reproducibility' checks. (The edu allocation is way too small for my large classes).

we released olmo 32b today! ☺️ 🐟our largest & best fully open model to-date 🐠right up there w similar size weights-only models from big companies on popular benchmarks 🐡but we used way less compute & all our data, ckpts, code, recipe are free & open made a nice plot of our post-trained results!✌️

Great to see you at #COP30, Governor @gavinnewsom.bsky.social! Magali de Bruyn (R) and McKalee Steen (L) are leading several events @ COP30, including providing recommendations for how Indigenous communities can leverage tech and #DataScience to advance #EnvironmentalStewardship and #Sovereignty.

This seems important. Current AI models can't read graphs. They "see" what they expect to see, even if the data shows something else.

Wow, rio-stac-io looks awesome! github.com/planetlabs/r... Anyone have a chance to compare this to the odc-stac approach? ( @mdsumner.bsky.social 👀 ?)

sad to be missing #jupytercon this week! But small win, recently made my first PR to JupyterHub fancy-profiles to add support for ARM architecture. & now I have JupyterHub running on an NVIDIA DGX Spark (via k3s). Also have CUDA/RAPIDS based image in rocker for python+R envs, rocker/cuda:arm64

Raise your hand if you're going to #JupyterCon 🙋‍♀️ See you there @ucbids.bsky.social! #JupyterCon2025 #DataScience

🚀 anymap v0.6 is here! This release comes packed with major new features. These updates make interactive geospatial analysis in Python smoother and more powerful than ever. 🔗 GitHub: github.com/opengeos/any... 📘 Docs: anymap.dev #python #geospatial #jupyter #dataviz

The 1.4 release of @duckdb.org supports using a DuckDB database to serve vector tiles! Of course, I had to try this out in R. Check it out: all 242,000 US Census block groups dynamically served as vector tiles from a DuckDB database, displayed on a MapLibre map from R in Positron.

All 8.1 million US Census blocks. Visualized smoothly in 3D. Instant population and housing totals from a lasso selection. All running seamlessly in the browser, no traditional backend. While everyone’s talking about AI, it’s an incredible time for geospatial tech.

Really thrilled to see the renewed momentum from @ucbids.bsky.social on open source infrastructure! A new partnership with @2i2c.org puts supporting tools, their developers, and their community at the center. cdss.berkeley.edu/news/berkele...

mid-semester surveys are in! Is it terrible that I do a happy dance when reading that most students felt "the heavy use of AI was either not helpful or detrimental to learning?" YES dear students, you are smarter than the bots. and now you know it too.

here we are in the last week of module 2. 120 students, majority new to coding, are set up with their ipynb's in VSCode+CoPilot agent mode (w/ sonnet 4.5, GPT5-codex). As they plug away in pairs writing some of the best code & analysis this module has seen. remarkably little use of the bots!

Media still largely misses the RL part of training LLMs. NY Times: > they’re computer models trained on massive amounts of text to predict the next word in a sentence. What feels like empathy or validation is really just the A.I. chatbot echoing back language patterns that it’s learned.

NSF GRFP solicitation is finally up. Life Sci deadline extended to Nov 10 but 2nd year grad students no longer eligible www.nsf.gov/funding/oppo...

Increasingly convinced that the advances we will see with 'AI' in the next few years will come not from more bigger NN models replacing tasks done with conventional programming, but from greater tool use from models.

I reference data science at the singularity constantly as it's not just a model of why data science blew up, but also how any field or org can organize itself around data, code sharing, and benchmarks: arxiv.org/abs/2310.00865

Okay, but Claude's commentary while helping me set up a ray cluster on National Research Platform (NRP) is pretty entertaining: Claude: (proposes 2 worker-config) Me: why two workers? Claude: (queries resources) Claude: "HOLY MOLY! Your cluster has nodes with 57TB of memory and 13,800 CPUs!"

You still have 5 days to apply for this awesome postdoc opportunity in the Environmental Data Science Innovation & Impact Lab at the University of Colorado-Boulder! This could be your backyard!

Like many, I've struggled with students merely pasting LLM outputs as their own work. But this year when I encourage them to use AI in generating code they need, now they ask all these critical questions like: 'but is this output ok? how do I know? how could it be better?'

Also exciting to see the new fully open (training data, weights, training details) LLM from the Swiss, 'Apertus' www.swiss-ai.org/apertus ! Shipped in both 8B & 70B params on HF, over 40% non-English sources. Support for vllm + public web interface (via publicai.co). Impressive.

Very interesting project from @ai2.bsky.social , a fully open, agent-based LLM for academic literature asta.allen.ai . Nice overview at allenai.org/blog/asta

Great post-doctoral opportunity at @cu-esiil.bsky.social jobs.colorado.edu/jobs/JobDeta...

Excellent post from @beenwrekt.bsky.social here on failure of AI safety. While much is familiar, he makes an excellent pt that the solution is obvious and do-able: terminate the conversation (hilariously illustrated by Claude's refusal to answer bio sciences qs). www.argmin.net/p/the-banal-...

Ethemblage is an online game developed by @leahgovia.bsky.social leahgovia.itch.io/ethemblage It's a story in which players interact with different scenarios where technologies such as acoustic monitors, drones, and GPS collars are applied by conservationists to monitor non-human species.

2/ Understanding where, when, how, and why wildlife is declining is key for effective conservation By tapping into participatory science, we now have a (biased) complementary way to monitor mortality events in near-real time 👉: huggingface.co/spaces/diego... I’ll highlight four case studies ⬇️

Really re-energized and inspired after the CA 30x30 Summit in San Diego! Amazing to see what this community -- from gov't agencies, land managers, tribal leaders, performing artists and everything in between -- can do together. sites.google.com/view/2025-30...

Really pleased to see more investment in truly open models. Ai2 has been a real leader in this space with OLMO but much more is needed.

From @posit.co 's coffee chat this morning: @hadley.nz is "80% confident" that it's still a good idea to learn data science coding. But recommends you also know how to do something with your hands. #teaching #llm

Or me! I’m right next door to the math building if they need to chat fossils with someone. :)

We should broaden models, not narrow them. Models are tools to explore uncertainty, communicate scenarios, and test policy. Managers seek robust strategies, not perfect forecasts. What a great paper from @cboettig.bsky.social onlinelibrary.wiley.com/doi/10.1111/... #Forecasting #Ecology 🌐

I understand that HuggingFace is blocked in China, but collaborators at US NGOs and State gov't agencies also report they cannot access anything at huggingface.co domain. Any idea why this is? Can speculate but can't find any documentation on this...

Attempted to vibe code my course's module 2 on fisheries collapse (github.com/espm-157/fis...) in Claude Sonnet 4 via VSCode-copilot: I try not to write any code, but provide feedback and directions as it gets things wrong (or stuck). Struck by just how much this feels like working with students

📣 Join us for our AGU2025 session IN029 "Open Source Geospatial Workflows in The Cloud"! Can't wait to see you there :) Submissions are due *Wednesday, July 30*! Visit our website for more details and to submit: events.geojupyter.org/conferences/...

So important for students to understand how different “homework questions” are from real world tasks for LLMs. HW is carefully crafted to test one concept with no extraneous issues in the way - no running out of RAM, confusing complex metadata , etc etc

Claude Sonnet 4 via CoPilot Agent does do far better on module 1 of my fall course than it did last fall; mostly thanks to tool use being able to debug data parsing. still struggles throughout, needing user help to get unstuck. took ~ 3 hrs of me helping it (about double me doing without).

The Environmental Policy Lab at @ethz.ch is hiring! 🌱 A Postdoc broadly interested in resilient data infrastructure & policy for biodiversity governance 🌱 Two PhD students interested in biodiversity policy and spatial planning more info here: epl.ethz.ch/the-group/op... Please share widely! 🌍

No words.

Following on arxiv.org/pdf/2502.00873, I think this speaks volumes. much better to learn the right abstractions. And where the right abstractions remain more contested, things will probably remain dicey for a while.

Get the word out far and wide. New opportunity from the Simons Foundation in the Eco-Evo space. 2026 Simons Graduate Fellowship in Ecology and Evolution Awards, due July 31, 2025, only for incoming PhD students who plan to start their PhDs in Fall 2026. www.simonsfoundation.org/grant/simons...

Hearing from former students about the awesome things they are now doing might be the best part of this job. And at a moment when it "environmental justice" is being purged by newspeak it's reaffirming to hear how often former students mention that module in particular.

student is horrified to see my github commit log consists of nothing but varying animal emojis 🦆🦁🐟🐸🦎🐝🐙. Not sure if it was more from my blatant disregard of my own teaching about good commit msgs or my blatant disregard towards plant diversity? 🌲 🤔

Many processes from industry are not appropriate or overkill for an academic setting, but we can and should be doing better than we currently are. Our paper tries to give practical advice on how you can improve your scientific workflow, without being a coding guru. www.nature.com/articles/s44...
