For the first time since 1992 (when I was 12) I’m completely disinterested by the UK General Election.

Sunak and the Tories will lose, Labour in uninspiring, the Lib Dems weedy, Greens weak and SNP weakened, and Reform simply grim. And Brexit is the elephant none of them will touch.

As I’m still a UK citizen I will vote, but it’s with less determination than ever before.

If I may: Greens are weak because people don't vote for them. Perhaps it's time to give them a strong chance – seems to be the only party still saying Brexit was a terrible mistake.

The ToR browser is really helpful here. All they seized was a domain name, not the actual server. Accessing alternative domain names that lead to the same server remains possible. Via ToR in particular.

libgen doesn't charge. b-ok.cc attempts to charge you, and the book collection is the same. I don't know it for sure though.

Last week there was a discussion in Leipzig city council about a seed library. A concept is now to be developed with partners!

I'm already looking forward to seeing online in the future where such seed libraries exist.

http://seedlibraries.weebly.com/

I also have a lot of questions: e.g. Does anyone know of a study on the effect of such seed libraries?

Not only market forces, also changes in habits and behaviours.

As an amateur baker, the bread I make is order of magnitude cheaper than when bought at the bakery, but for my time; the flour is barely a factor in the cost so splurging in fancy flours is possible: a 1 kg of fancy flour only costs 2 to 3 times as much as 1 kg of plain flour. And despite that a fancy flour baguette comes at ~35 cents of raw material. No market force here.

But what fraction of families bake at home, or cook at all for that matter, in the Western world? So the demand for good raw foods is low. Restaurants spice up and sell low quality stuff at high prices.

But that cost of time is not a cost at all, it's not time wasted, it's family time, social time, being together time, lovely time that makes for good memories of companionship, warmth, cooperative behaviours, constructive life-long busyness, a reference lifestyle, immersed in good smells and flavors to anchor taste and preferences for decades to come.

Just read a fantastic one, on the work of John Letts, from 2001:

"No one had excavated a thatched roof before."

"Before systematic crop breeding, cereals evolved into local land races. Different soils, slope, shading and drainage gave endless possibilities for adaptation. With variety in the seed stock, crops would grow differently even across a single farm. Whatever the weather or diseases, something would always flourish."

"Old thatch provides an opportunity to study this lost diversity. Letts often finds a mix of bread wheat, English rivet wheat - not grown commercially for more than a century - rye, oats and barley. He has also found 35 different weeds, from corn cockle and cornflower - now vanished from English farms - to yellow rattle and cow wheat."

On time: 5 minutes to mix, and 5 minutes to roll the dough into baguettes some hours later. Actual total work time is 15 to 20 minutes tops. One just has to plan around the waiting times.

On cooking cost: depends on the efficiency of your oven and how many you bake at once. In our case, our electric oven when used during the day can draw from solar panels.

On baguette cost: a lot of the weight is water. A 500g bread loaf does not have 500g of flour, nowhere near. Closer to half of that; water loss during cooking is not that great.

Rewilding the internet:

"Just like the crime-ridden, Corbusier-like towers Moses crammed people into when he demolished mixed-use neighborhoods and built highways through them, today’s top-down, concentrated internet is, for many, an unpleasant and harmful place. Its owners are hard to remove, and their interests do not align with ours."

"Apple and Google’s email clients manage nearly 90% of global email. Google and Cloudflare serve around 50% of global domain name system requests."

"For many people across the generations today, platforms like Facebook or TikTok are the internet. They’ve long dwelled in walled gardens they think are the world."

If you only read one article this year, it has to be THIS by @Mer__edith, the president of :

"AI is a marketing term, not a technical term of art. [...]
This is also why it’s imperative that we recognize mass surveillance – and ultimately the surveillance business model – as the root of the large-scale tech we’re currently calling “AI”."

"When and why does motor preparation arise in recurrent neural network models of motor control?"

"we modelled the motor cortex as an input-driven dynamical system, and we asked what the optimal way to control this system to perform fast delayed reaches is. We find that delay-period inputs consistently arise in an optimally controlled model of M1."

Current biases and trends in scientific journalism. Study from a sample of Nature articles:

"we found a skew toward quoting men in Nature science journalism. However, quotation is trending toward equal representation at a faster rate than authorship rates in academic publishing. Gender disparity in Nature quotes was dependent on the article type. We found a significant over-representation of names with predicted Celtic/English origin and under-representation of names with a predicted East Asian origin in both in extracted quotes and journal citations but dampened in citations."

"workers are not simply scaled-down versions of queens that have lost their wings."

"Instead workers have a distinct thorax architecture with an enlarged muscle system to strengthen the neck and increase the range of motion of the head ... appears to be a key adaptation to allow ants to lift and carry objects or prey that are many times their own weight"

Why would anyone inflict MSWord on themselves. Puzzled here.

@steveroyle

In such cases, I write latex or markdown and then pandoc to DOCX, then copy-paste into the funding agency's tabulated template.

Because actual writing in MSWord is infuriating, particularly when aggravated by a straightjacket template that keeps complaining and moving text around.

First book revisions. Tips?

(Academic press) book pre-publication reviews are back. Really positive. YES!!!!!!!!!!!! 🎉​🎉​🎉​.

So now I'm moving onto final revisions. It feels good to slip back into that headspace again.

My big question for anyone who has sent a book off to the world: What was your strategy for those last steps? There's addressing the feedback, of course. But after that? It will never been perfect. But it has to be great. How do you know when to let it go?

albertcardona,

@NicoleCRust

Not having written any book, but having found many typos and wrong formulae in books, I'd say, make sure the draft is seen by many eyes to catch them all. It's not like you can publish an erratum; won't reach someone's bookshelf.

Celebrating with 3 observations at this afternoon:

A masked bee sits attentive on a green leaf, its body entirely black but for its white face and shoulders, and white marks on the legs.
A leaf-cutter bee forages nectar in a flower with pink, bell-like petals that form a cup over it.
