A workshop we're running at ECMWF in November - and very much not just for the weather/climate crowd. There are five confirmed keynote speakers from JCSDA, DKRZ, Météo-France, RMIB, and the Met Office.

If you work with large/complex scientific codebases anywhere (CFD, materials, plasma, astro...), and are thinking about software sustainability, please consider submitting an abstract by 4 September: https://events.ecmwf.int/event/529/

Workshop on software strategies for sustainable physical modelling

Overview This workshop will address the critical needs for a sustainable physical modelling capability over the next decade, amid uncertainties in HPC technology, programming languages, and scientific strategies. We will explore how to best achieve a forecasting system that can adapt to current changes in circumstances and requirements for model development. These include the rise of machine learning, which is becoming both a tool for software development and a foundation for emerging...

ECMWF’s portable global forecasting model OpenIFS now available for all

OpenIFS is now open source, expanding global access, accelerating innovation and strengthening collaboration.

ECMWF
We've gradually made some components of the IFS open-source over recent years, such as the radiation scheme (https://github.com/ecmwf-ifs/ecrad), wave model, and land-surface model. But now we're able to release the full forecast model - no licence, no restrictions. (No data assimilation either though.)

ECMWF's OpenIFS weather forecasting model is now fully open source on GitHub.

OpenIFS is a version of the same system used to produce our operational forecasts. After 15 years of licensed access, it's now genuinely open - publicly available with an Apache 2 licence.

«The whole thing is a mess and yet another embarrassment for the UK. And they were all warned about it, while insisting these concerns were exaggerations. But this isn’t just about the UK—it’s a cautionary tale for every democracy grappling with how to regulate the internet»

Go UK, "yet another embarrassment" is just too fitting 😅

Didn’t Take Long To Reveal The UK’s Online Safety Act Is Exactly The Privacy-Crushing Failure Everyone Warned About

Well, well, well. The “age assurance” part of the UK’s Online Safety Act has finally gone into effect, with its age checking requirements kicking in a week and a half ago. And what do you kno…

The mathematician John Venn was born on this day in 1834. To commemorate the occasion, here’s a poem in the form of a Venn diagram.

For the next three years I'll have the (additional) post of Frank Jackson Professor of the Environment at Gresham College, giving a series of free public lectures on Earth and how it works. All will be freely available online. You can see their whole programme here:

The UK Online Safety Act has erected an age wall through the Internet 🚧

UK users are forced to accept censorship or hand over sensitive data to unregulated providers.

The government’s response? You’re a predator 🤨

Enough. Tell your MP to fix it now ⬇️

Tell your MP: The Online Safety Act isn’t working

What's the problem? The Online Safety Act has been a disaster. Rather than protect children, millions of adults are facing widespread censorship, and teenagers are having their freedom of expression restricted. Here are some of the key problems with the law: Wrongful Censorship: The law places huge liabilities and threats of jail on platforms if they don't censor the right content. It does little to protect freedom of expression. The results are in. Footage of protest censored on X. Subreddits about stopping smoking, sexual health, and the news age-gated and shadow-banned.

#Libdems opposition to the #onlinesafetyact is beginning to snowball

Quite rightly, they are asking for suspension and a rethink.

Where is the opposition within Labour, Jeremy Corbyn's new grouping and the UK Green Parties? I hope they can also speak out against this car crash.

We have a duty of care to speak out against the Online Safety Act

We are the party of civil liberties – that is what, we would argue, should be an uncontested fact. From the Snoopers Charter to campaigning for equal rights for minority communities, it is the raison d’être of the Liberal Democrats and the Liberal Party before us to stand up for civil liberties, recognising that the...

Interest in LibreOffice, the open-source alternative to Microsoft Office, is on the rise, with weekly downloads of its software package close to 1 million a week as users look to avoid subscription costs. That’s the highest download number since 2023. It works on Linux, macOS, Windows and Unix like systems. https://www.computerworld.com/article/3840480/libreoffice-downloads-on-the-rise-as-users-look-to-avoid-subscription-costs.html
