I'm building a neural net that predicts stability of solid phases. The details are not quite settled yet, there's a lot of trial going on. Generally it's a classifier that guesses if energy above the hull is greater than zero or is equal to zero.
Convex hull is a thermodynamic concept: set of compounds that are thermodynamically stable, and their unstable polymorphs are higher in energy (hence E above the hull).
@academicalnerd Looks cool, I had a friend who was working on something similar (if I correctly understood what you're doing...).
How do you represent phases in a computer? Do you place the dustances and angles of all the molecules or something like that?
@post @poterealpopolo non conosco questa teoria, leggerò qualcosa a riguardo.
Puoi consigliarmi un compendio introduttivo non troppo lungo?
Ciò detto, non vedo come il salario minimo possa guastare qualora venga aggiustato regolarmente all'aumento dei prezzi.
Magari non risolve i problemi ed aumenta la quantità di lavoro in nero, però quantomeno stabilisce che a noi come società certe cose non vanno bene, non sembrano accettabili e che se qualcuno paga da fame i suoi dipendenti sta commettendo un illecito.
@TheStrugglingScientists But most importantly, how many have died from it after it was banned?
@poterealpopolo Non vedo perché questo dovrebbe provare che gli stage andrebbero aboliti.
Questo dovrebbe portare semmai all'introduzione di un salario minimo umano che permetta ad una persona di affittare una stanza, comprare il cibo necessario per sopravvivere un mese includendovi un po' di carne ed avere qualche soldo in più in tasca a fine mese per svago ed altri progetti.

RT @Giul_Granato@twitter.com
Una SpA che fattura più di 20mln di € l'anno cerca personale con “Master in Gestione Risorse Umane e ottima conoscenza della lingua inglese e di Excel” in cambio di uno schifo di stage pagato 500€ al mese.
3,12€ l'ora.
Basterebbe questo per dire che gli #stage vanno aboliti.
@academicalnerd What are you working on?

I've been sharing @skrishna 's guide to Mastodon with people. I found it very helpful myself! It's not just technical but also about the culture of Mastodon. #mastodonhelp #guide https://www.swapnakrishna.com/blog/mastodon-primer-part-2
@allinone0@fosstodon.org It appears to me that a large number of researchers is moving here; that's quite cool.
If it's only researchers it should be fairly quick to actually integrate them.
@cypher07h @allinone0@fosstodon.org @MattTheQuick As far as I heard there's a huge Japanese instance that makes up for a large part of the total user base.

@academicalnerd I mean, if you're working with ML for chemistry the utmost important problem is finding some reliable data to use; then how to represent chemical data in a machine interpretable way and then training ML models.
If you're going into NN I hope you've got a lot of data to throw at it.

I've been working with a bunch of ML and quantum chemistry lately. At this point the hardest part is to actually come up with the problem (i.e. translate chemistry into reasonable mathematical expressions) and then make all the servers and packages work. The code and NN architecture themselves are like 10-20% of the work.
@GustavinoBevilacqua @neurob Quello si, ma per ora non ho visto alcuna domanda del genere...
Si vede che mi avranno bloccato da mastodon.uno a questo punto
@zeppe Ciao, io da quando è successo mi sono rimosso l'applicazione dal cellulare così non mi mantiene la posizione nella timeline e non posso leggere tutto.
Rimuoviti qualche iscrizione e prova a dare un'occhiata al #GustavinoRatio per misurare come vanno le interazioni con gli altri utenti con gustavino.crucitti.xyz
@neurob No dai, questo non si fa.
Poveri ragazzi già sono stati scacciati dal loro social e si ritrovano qui spaesati e poi andiamo pure a dirgli RTFM?
Cari nuovi utenti, se vi sentite spaesati o volete aiuto chiede pure qui o con un messaggio privato!

I mentioned this in a private message to someone recently about why a small handful of servers block qoto. I wanted to reiterate it here for the new comers on QOTO who dont know the history:
So there are some servers out there that demand every server int he network block every instance they do, and if a server doesnt block an instance they block then they block you in rettatliation.
Their reason for this is quite flawed but it goes like this.. If we federate with a bad actor instance and we boost one of their posts then their users will see it and defeat the purpose of the block. The problem is, this isnt how it actually works. If they block a server and we boost it, they wont see the boost, thats how blocks work.
The issue becomes even more complicated when you consider the fact that these servers, by virtue of their policy, have huge block lists where they block tons of major servers. So in order to satisfy them we too would have to block a huge number of servers.
This means you have a choice, you either join a server that isnt blocked, but has a huge block list themselves, or, you join a server that doesnt block and be blocked by a small handful of servers. Obviously that means on QOTO you will have bigger view of the world than you would on any of these others servers. In fact QOTO has onne of the largest federation footprints of any server in the network.
I want to also explain why we choose the decision we did. Years ago when this controversy started and servers across the fediverse started blocking there was a divide of people taking sides. WOTO was one of the few servers that didnt take sides and allowed people read content from any server (but with strict hate speech rules). This caused a huge influx of people,s pecifically from the LGBTQ community, onto our server. It turns out many people relied on us not-blocking for their physical safety. There were big name biggots (like milo yanappolus) who were on the network. They used their accounts here to watch his account for doxing so they could warn themselves and their community and protect themselves accordingly. In fact we added a feature just for them called subscriptions which allowed them to monitor accounts without following them so they could do so anonymously.
In tthe end for the safety of the LGBTQ community here we refused to engage in mass server blocking and instead encouraged our users to block servers on an individual basis and provided access to block lists for them to do so. But some really misguided servers blocked us anyway.
Thankfully the servers blocking us are few and far between and are limited to only the most excessive and aggressive block lists. As I said, QOTO has one of the largest federation footprints on the fediverse,
@ToxWells @lordmax Try to make friends as you would do in a bar rather than advertising yourself in a TV screen.
Thus: slowly meet and talk with people from your instance, get to know the people they know and so on.
I'm not saying you should not advertise what you do and what you like; but definitely not follow people just because they're interested in the same things.
@freemo I think a slower growth is better. Since now people have started migrating in communities however I believe the amount of new users will increase in the future as more and more people belonging to those communities will get to know about it.

Questo è vero; non credo assolutamente in uno spostamento di tutti gli utenti Twitter su Mastodon.
Tuttavia ci sono certi gruppi che si stanno spostando in massa e rinnegando Twitter.
Questo significa che Mastodon diventerà il luogo di ritrovo di quelle persone e che le altre persone che erano interessate in quelle cose prima o poi si sposteranno su Mastodon.
Ad esempio: io ho notato una grande migrazione di ricercatori anche famosi. Questo significa che i ricercatori su Twitter saranno comunque spinti a spostarsi su Mastodon, a prescindere dal cambio delle regole su Twitter.
Questa mi sembra la grossa differenza con la prima migrazione: nel primo caso si è iscritta tanta gente "isolata"; mentre in questo caso si stanno spostando intere comunità.
