China Plans to Dominate a Key Semiconductor Material(Polysilicon).
- Polysilicon is often described as one of the purest materials on Earth. It is used as the substrate material for a range of products, most importantly chips and solar panels.
- Beijing has provided significant support to its domestic polysilicon industry to establish Chinese firms as the dominant global suppliers of solar-grade polysilicon and is seeking to push its firms to expand their share of semiconductor-grade polysilicon.
- Chinese overproduction of polysilicon and silicon carbide is causing the global price for these materials to crater, undermining the short- and long-term financial viability of leading firms in the United States and allied countries.
- Forced labor has already been linked to China’s critical minerals sector, in particular rare earth mining and refining, increasing the likelihood that forced labor is integrated into China’s polysilicon supply chain.
- The Commerce Department has launched a Section 232 investigation into polysilicon and derivative products, providing a unique opportunity to ensure that critical infrastructure supply chains do not become dependent on Chinese inputs.
- The administration should prohibit imports of Chinese-origin or -linked polysilicon or derivative products, and require products containing Chinese-origin or -linked polysilicon to document that no forced labor was used in their production.
- The departments of Commerce, Defense, and Treasury should support U.S.-based expansion of polysilicon and silicon-carbide production capacity.

«Not Even The “Tech Bros” Want Their Own “Tech”» — «Nemmeno i Techbro Vogliono la propria Tecnologia»
youtube.com/watch?v=a-YVtACnfW…A proposito dei ricchi e motivi per odiarli, ho trovato questo video che spiega quanto la situazione è greve con la Valle del Silicio… o meglio, ciò che un tempo era il posto del silicio e oggi è diventato il posto dello schifo, il quartier generale di centinaia di signori del male digitale, per mano dei quali la parola “utente” assume un significato più distante dall’accezione informatica e più vicino a quello con cui gli spacciatori si riferiscono a chi compra le loro schifezze… 😷
I techbro di queste grosse aziende (non nello specifico le FAANG, anche centinaia di “minori”) sono non solo stronzi, in quanto perfettamente consapevoli di contribuire direttamente alla creazione di prodotti e servizi equiparabili a droga, software sempre in qualche modo dannoso per la psiche umana, nonostante sono loro che fanno le decisioni (insomma, parlo più di manager e salcazzi vari, non coloro che scrivono il codice sotto gli ordini dei draghi sputafuoco; anche se, qualora siano molto ricchi anche loro, non saranno risparmiati)… Sono soprattutto giganteschi ipocriti, che in primis si fanno riserve sull’usare la loro stessa tecnologia! 🤮
Il video fa diversi esempi, uno più allucinante dell’altro, ma secondo me il peggiore (cioè, quello che funziona meglio) è il fatto che i techbro restringono questa tecnologia in famiglia, andando dal non usarla a casa fino al bandirla completamente ai figli! Probabilmente molti conoscono quello che all’epoca pareva un caso eclatante, cioè che Steve Jobs non lasciava usare ai suoi figli (piccoli?) iPod e iPad… ma io ignoravo (e penso quasi tutti, altrimenti la società non sarebbe come è oggi) che nel salotto cattivo della California questa fosse praticamente la norma… 😱
…Ma, non solo niente tecnologie smart moderne AI agile connection cloud touch ai figli, ma addirittura niente in generale… neanche a scuola: li mandano in istituti di primo e secondo grado che costano più di una fottuta università (ricchi di merda) e dove, a differenza di qualsiasi scuola per persone normali, per i figli del popolo e non di un élite dei miei coglioni, tutto viene fatto senza alcuna tecnologia, perché si ritiene (forse non a torto, stando alle statistiche) che evitarla completamente porti più pro che contro nell’ambito dell’istruzione. E se è davvero così come si pensa, è gravissimo, perché vorrebbe dire (come se non ci fossero già altre mille conferme a riguardo, vabbé) che tutta la storiella delle pari opportunità sotto il nostro sistema economico, che ognuno può “farsi da sé”, è una stronzata colossale: i bambini non hanno margine di manovra, e non sono loro che scelgono se andare ad una scuola per ricchi dove imparano veramente, o una normale dove si brainrottano. 😫
Ora, io personalmente spero che questi bambini non stiano totalmente a secco di tecnologia, perché sarebbe triste… cioè spero abbiano almeno un 3DS per fare il gaming e magari foto e video, e quantomeno un PC a casa per rovinarsi già in tenera età con il coding, o fare un server Minecraft, o creare siti web, non lo so… Però, a parte la mia opinione personale, la situazione è oggettivamente vomitevole. Questi ricchi bastardi, che sono per esempio capi di social network (come uno di Facebook nel video), non lasciano usare il social ai figli non per i motivi soliti e giusti del tipo di “è pieno di pedofili” (cosa a cui risponderei di sistemare la moderazione, merde!), o che dovrebbero tenere d’occhio cosa ci fanno sopra ma non hanno tempo… glieli vietano per la struttura in sé: perché queste piattaforme sono fatte apposta, come sappiamo, per causare assuefazione. 😶
Io, come sempre, non ho parole. Questi minchioni sanno perfettamente i danni che il loro “lavoro” causa alla società, e invece di cambiare rotta se ne fottono — ma, non quando si tratta delle persone a loro care. Un comportamento immorale e sociopatico a dire poco… e io, veramente, non so come devo fare ancora a vivere in un mondo così terribile, visto che la gente non si sveglia e quindi fare una rivoluzione a livello mondiale, che è l’unica rivoluzione che funzionerebbe, è praticamente impossibile. 😭😭😭

Abbiamo bisogno di un mondo cucito su misura?
Buongiorno a tutti, sono Erika e apro con piacere un piccolo mondo dedicato al cucito.
Perché potremmo avere bisogno di questo spazio? Perché cucire è un intimo atto politico, di resistenza ma soprattutto di amore.
Per approfondire questo aspetto consiglio la lettura di ‘I fili della vita’, Clare Hunter, edito da Bollati Boringhieri.
Ma inoltrandoci un po’ più nel vivo della questione, vi propongo una delle mille possibilità con le quali approcciarsi al mondo del cucito e sarei felice di sapere la vostra.
Cucire la necessità.
Parliamo di cucito sartoriale e creativo, senza distinzione. Reinizia la scuola, ci serve un astuccio: cuciamolo. Abbiamo le mestruazioni e ci rendiamo conto che abbiamo voglia di fare la differenza, disegnandoci un cartamodello di assorbenti su misura. Mutande lise? Cuciamocene un bel paio! Grembiule per non sporcarci? Ecco fatto!
Non si arriva a fare tutto dall’oggi al domani, ma con il sostegno dei tanti account che condividono gratuitamente le loro esperienze, qualche libro e qualche modellista che vi vende le sue preziose idee su carta (la conoscete mammaconstoffa, Elisa Masi?) ), ecco che abbiamo le basi per partire!
A proposito, urgono contenuti liberi anche su #peertube. Chi si propone? 😀

Every lens leaves a blur signature—a hidden fingerprint in every photo; With it, we can tell apart ‘identical’ phones by their optics, deblur images, and render realistic blurs.
cross-posted from: programming.dev/post/37278389
Optical blur is an inherent property of any lens system and is challenging to model in modern cameras because of their complex optical elements. To tackle this challenge, we introduce a high‑dimensional neural representation of blur—the lens blur field—and a practical method for acquisition.
The lens blur field is a multilayer perceptron (MLP) designed to (1) accurately capture variations of the lens 2‑D point spread function over image‑plane location, focus setting, and optionally depth; and (2) represent these variations parametrically as a single, sensor‑specific function. The representation models the combined effects of defocus, diffraction, aberration, and accounts for sensor features such as pixel color filters and pixel‑specific micro‑lenses.
We provide a first‑of‑its‑kind dataset of 5‑D blur fields—for smartphone cameras, camera bodies equipped with a variety of lenses, etc. Finally, we show that acquired 5‑D blur fields are expressive and accurate enough to reveal, for the first time, differences in optical behavior of smartphone devices of the same make and model.
Every lens leaves a blur signature—a hidden fingerprint in every photo; With it, we can tell apart ‘identical’ phones by their optics, deblur images, and render realistic blurs.

in reply to Sunshine (she/her) • • •And the majority of Mastodon users will think that Gargron has introduced quote-posts to the Fediverse.
What next to nobody on Mastodon knows is that the Fediverse has had quote-posts for a bit over 15 years, namely since the launch of Mistpark (today known as Friendica) in 2010. That's not only longer than the term "Fediverse" is old, it's also longer than Mastodon has been around.
For as long as Mastodon has existed, it has been possible to quote-post just about anyone and anything on Mastodon.
