URGENT ACTION 🚨 If you do one thing for trans rights today – contact your MP about the proposed EHRC Code of Practice, which would devastate trans people's lives. Even if you've sent a letter before, make sure you use our new tool to send another. Now is the moment to keep the pressure up 👇

🚨This is urgent🚨 Bridget Phillipson, the Minister for Women and Equalities, has a decision to make. The EHRC, a regulator mired in controversy over anti-trans views, has sent a new draft Code of Prac...

just wanted to share that after nearly 8 years of programming in Python and dabbling with other languages as-needed, I've finally written my first bash script! having random blind spots as professional does not make you bad at your job, and i just wanted to normalize that :)

with how good AI-assisted coding is now, are programmers going to become more of a luxury trade? "We hand-craft artisanal Python code to solve your use-case. Experts weave every letter of the variables into your codebase. All commits are done manually -- personalize your messages for a small fee."

being 194cm, this has always been the most frustrating thing about living & travelling in the uk compared to the rest of europe -- i have to go out of my way to get stupidly wide beds just to increase the length & not have my feet dangle off the end 😭

Today, we’re announcing the preview release of ty, an extremely fast type checker and language server for Python, written in Rust. In early testing, it's 10x, 50x, even 100x faster than existing type checkers. (We've seen >600x speed-ups over Mypy in some real-world projects.)

well, this is a new one for me 😄 turns out that python's list creation shorthand for duplicating elements (e.g. x = [obj] * n) does not make the instances of obj distinct in memory! TIL.

<proud advisor> Hot off the arXiv! 🦬 "Appa: Bending Weather Dynamics with Latent Diffusion Models for Global Data Assimilation" 🌍 Appa is our novel 1.5B-parameter probabilistic weather model that unifies reanalysis, filtering, and forecasting in a single framework. A thread 🧵

idk if this is a neurodivergent thing, but having a low-volume audiobed with some kind of background music can really help me stay in long meetings when i'm remote. i'd recommend giving it a try if your concentration can waver easily — i find it surprisingly grounding!

A friend included this anti-acknowledgement section on her PhD thesis. She also added the proposition: “Systematic bullying and undermining of girls and women in STEM starts early on and is the reason why they do not stay in science and related fields.” Absurd we still need to go through this 🧪👩‍🔬

There have been people less than helpful in my journey here. I wanted to acknowledge those too, bc I know I am not unique in this experience.
No thank you to the physics study assoc that made me sing songs about how women couldn't study physics without sleeping with the professor, the day I stepped into university life. No thank you to the 5th year physics student that decided to assign me a stripper name within the first minute of meeting me in the physics coffee corner in my first year. No thank you to the technician that was responsible for onboarding me on the use of the cluster in my third year who raised his eyebrows and asked me if that meant I was some sort of computer girl. No thank you to the senior researcher that sent me utterly inappropriate texts after a conference, then proceeded to apologise months later by telling me they had not been meant for me anyway so no hard feelings remain hopefully And no thank you to him for attending every conference I've been to since. No thank you to the people who told me that it was surprising that I was doing a PhD since I was a girl. No thank you to the man who mistook me for a coffee lady at a conference, and after having to correct him two times that I did not work there, responded with you should consider it. No thank you to the researcher that asked me what I was wearing underneath my outfit during a conference. No thank you to the physicist who declared to a room full of other physicists that biologists don't know how to design an experiment. No thank you to the people who have called me scary instead of strong and intimidating instead of intelligent.
And finally, no thank you to the exec board of the TU Delft, whose knee-jerk reaction to being held up a mirror about the social safety at the university, was to sue the party holding up the mirror instead of looking at the problems they highlighted.
... You have made me feel like I do not belong in science & I cannot forgive you for that.

Mark today in the history books. The first AI weather prediction model labeled “operational” by a major world forecast center. Congrats ECMWF 🎉

ECMWF@ecmwf.int · 2y ago

We have taken our Artificial Intelligence Forecasting System (AIFS) into operations today to run side by side with our physics-based weather forecasts. The #AIFS outperforms traditional models for many measures, at a fraction of energy use. ➡️ www.ecmwf.int/en/about/med... #AI #MachineLearning

after enjoying some testing of @simonwillison.net's LLM CLI tool, going to try some more regular use of models for my more organisation-related tasks. what model would people suggest that meets these reqs: - long context (e.g. many long text files) - economic - if local, fits in 32GB mem?
