I like some concepts and design of Mbin, something to learn from, but I’d believe more in its growth potential if not written mainly in php.

Interesting observation and analysis, and illustrates the potential of more lemmy-mastodon interaction.
Indeed mdon like-federation seems weird but I presume it was setup this way for efficiency, to reduce the number of small communications? Although Lemmy has a backend in rust - more efficient than mdon’s ruby - still I wonder whether the lemmy system of federating all upvotes would scale well if the number of users grows to that of mastodon and beyond ? Could there be some intermediate compromise solution (e.g. federate batches of 100 likes)?

Indeed to use scala-native you’d need pure-scala libraries, but the core lib re-implements most java lib, and there are now small simple external libs available for common tasks like file management, database, etc. - for example check out the lihaoyi suite.
I mainly use scala-js (to make this) which was formerly a java app - as it compiles to both js and jvm (cross-project) can gradually convert stuff you already wrote. I’ve tried native for stuff like pre-processing data files.

I didn’t discover Lemmy through search, nor did I ever use reddit - I found it from mastodon where a few people promote lemmy posts. Then gradually realised I preferred the community-focus here, compared to the individual-focus of mdon (although combining both could be good). As mdon has many more users, improving this inter-op would help to bring people here.

Scala compiles either to native, js or jvm - obviously the IO / interface options vary between these envs, but the lang is the same. Recently Scala 3.5 incorporates a simple-to-use CLI which makes it easier to compile to native (or just run a small file as a script, or experiment with a repl), native binaries are small and fast, and there are some simple io libraries. Since you can also compile to jvm to interop with java, that might help with transition.

I now use Scala 3, and very happy with syntactic whitespace (combined with an intelligent compiler)

Well, in most countries wind and solar are rapidly growing compared to hydro. A more critical question for India is what else could replace the melting Himalayan glaciers and reducing snow cover, as a storage of water for the dry season?

Indeed that’s strange, and the flat slope in 2060 seems inconsistent with declared net-zero policies of China and even India. Russia has no such policy, but still strange to assume continuation of current government concepts there until 2060. (you can see the regional breakdown in supplem Fig 1. )

Regarding the map - an annual average cost is not so meaningful - in higher latitudes solar is not enough in winter - especially where it’s mostly cloudy during the first half of winter. Wind helps the balance but not everywhere, always. Of course, the sophisticated models behind the article know all that, the issue is simplistic presentation. I note “we assume hydrogen is used for seasonal storage” - this may be rather optimistic - how many dark months can that cover?

for info - lemmy even has its own beaver community - !Beavers@lemmy.world
(and plenty beavers thriving here by the Meuse in .be)

Tu as raison, ce ne sont pas des bonnes exemples, mais qu’est-ce que tu penses serait meilleur comme politique ? (c’est facile critiquer, mais le gouvernement d’espagne, dans ce cas, cherche améliorer un peu l’equilibre, il pourrait devenir pire )

C’est possible. Mais au moins, s’ils voyagent de façon légale pour passer telle expérience (un rêve partagé par nombreux, avant qu’il se reveille), ils auraient un peu meilleur chance défendre des droits d’emploi, et leurs familles payeraient moins aux trafiquants ?

Scala-js is working on it - as its compiler design may facilitate this.
I haven’t yet tried (on todo list) and am not an expert, but bookmarked in passing:
recent github implementation, some history, following older discussion

Seems like Germany has a good idea to vary it, to reduce pressure on travel. However we should think bolder still, reimagine the whole timing of the academic year which derived from nineteenth century traditions when children helped plant and gather crops. Now instead we should consider climate change, and July became too hot for comfortable travel in most of continental europe. So it would be better to have long holidays in May-June and maybe September, while also investing in cooling for school buildings (maybe more practical than for small homes).

Aucune réservation obligatoire (hors international) en Belgique, Suisse, Allemagne, Grand-Bretagne … Cette proposition est ridicule, on pousse les gens au voiture. Et la France avait si bon système de chemin de fer, avant qu’ils ont essayé copier l’aviation.

Vietnam is such a long-thin country, high quality rail infrastructure really makes sense given such a geography. I hope they connect their network west too, to other south-east asian countries, such network could also help to balance the development negotiations.

Interesting discussion. ‘Quit while ahead’ sounds obvious with hindsight, but who can say when a peak has been reached during events, and who, in such movements, would have the authority to impose that on others ? What could China learn from other countries ? For example, rapid student-led change in Bangladesh recently.

What better times? They’ll be competing with more solar and wind every year (also fewer people).

I think it makes sense. China also has a housing surplus, loads of infrastructure, plenty of educated graduates, and great diversity of climate (therefore resilience to that problem), but will lack young people to help with services. The first generation will feel discrimination (even europeans who’ve worked there know the laowai feeling) but attitudes could gradually change for their children.

Stability is indeed a strength of EU - effectively averaging over all the countries smooths over political oscillations - which is useful for tackling long-term policy problems (like climate). I’m not advocating majoritarian voting where 51% overrides 49%. However with ± 30 countries, one or two should not block the rest - the current system leads to transactional brinkmanship where the last hold-outs get some prize in return for postponed obstruction. I’ve seen similar (worse) problems in UN climate negotiations - also due to “consensus” principle.
