@mizer_model Pre-announcing mizer 3.0: growth diffusion, better numerics, interactive analysis objects, and composable extension chains. Please try the GitHub version and send feedback before the CRAN release.

@UoYEvents @CMO_England How can one join this online event? I can not find a link.

[Gustav Delius @gustavdelius]

From next Monday I will run a 3-week online course on multi-species size-spectrum modelling of fished ecosystems using the R package mizer. We will build and explore a model for the Celtic sea from scratch and you could build a model for your own region: https://t.co/cUZiVY47J6

As I am currently working on a #shiny app for @mizer_model , I just signed up for this talk.

[Ecological Forecasting Initiative @eco4cast]

The 2nd of 4 sessions in our virtual R Shiny Seminar Series is tomorrow TUES, AUG 17 @ 2pm EDT.
@margaretsiple
will be presenting on "Creative Visualization of Model Results and Uncertainty in Shiny". Details & registration link at: https://t.co/ldInv9td2I

It is amazing how easy it has become to share code. With the help of https://t.co/IOIU6SkdeI others can work with your code in their browser without having to install anything. https://t.co/l3npEwiDVf

[Gustav Delius @gustavdelius]

@CliveJFox I fully agree. I just had a narrow definition of "tool" in mind, taking it to mean software tool. That's the only reason why I said that the project is much wider than "tools" for EBM.

[Gustav Delius @gustavdelius]

@CliveJFox The tool we are going to use is the mizer multispecies dynamic size-spectrum model (https://t.co/j9rJ0U1eQR). But the project is much wider than tools for EBM. It will also try to change consumer behaviour in order to allow us to move towards ecosystem-friendly balanced fishing.

[Gustav Delius @gustavdelius]

mizer (https://t.co/j9rJ0U1eQR) now has its own twitter account, posting updates and tips for using the mizer package. Given that new functionality is added all the time, this should be a useful account to follow if you are using mizer.

[mizer @mizer_model]

One useful function that was added in version 2.2.0 is `animateSpectra()` that produces an animation of how the size spectra change with time in a simulation. You can see an example at

[Gustav Delius @gustavdelius]

We are being funded! Many thanks to @SMMR_UK and to our project partners. We at @UoY_Maths will develop the mathematical modelling to support the project's aim of sustainable #fisheries. We'll be hiring -- more next week.

My last tweet was over 12 years ago! I will now start tweeting more often about #sizespectrum dynamic size-based multi-species modelling of fish communities, in particular about new developments in the #mizer model (https://t.co/fBNGQYmCed)

@DegrowthPedia What happened to degrowthpedia? The url http://t.co/XTPHkcDcEW has disappeared.

Just realised that the Smoluchowski coagulation equation is a special case of our jump-growth equation (http://arxiv.org/abs/0812.4968)

[Gustav Delius @gustavdelius]

To speed up my stochastic simulation I need to learn how to best draw from a given distribution. Will read book http://tiny.cc/lznJb

[Gustav Delius @gustavdelius]

Have written and run my first real stochastic simulation using Gillespie algorithm with no less than 82500 reaction channels and 750 species

Returning from PANDA meeting in Leeds on "Patterns in Complexity" (http://tinyurl.com/cznjhz). Most interesting talks by Budd and Jensen.

[Gustav Delius @gustavdelius]

Just came back to York after 3 months in Berlin. Good time to start to twitter. Let's see how I like it.
