Inoltro da altra ml pubblica, sperando sia di interesse rob -------- Messaggio Inoltrato -------- Oggetto: [Linuxtrent] German Research Foundation: Data tracking in research Data: Mon, 7 Jun 2021 18:37:01 +0200 ... A: linuxtrent(a)freelists.org Ciao, il Committee on Scientific Library Services and Information Systems della German Research Fundation (DFG) ha pubblicato questo interessante documento sulle pratiche di tracciamento degli utenti da parte degli editori di riviste scientifiche e di servizi di indicizzazione: https://www.dfg.de/download/pdf/foerderung/programme/lis/datentracking_papi… C'è anche un appello da parte di ricercatori (per il momento soprattutto tedeschi) contro il tracciamento dei dati degli utenti che consultano o producono letteratura scientifica che chiede che gli istituti di ricerca sottoscrivano un Declaration of Research Assessment che proibisce di negoziare con aziende che usano il tracciamento degli utenti come business model: https://stoptrackingscience.eu/ I tedeschi su queste cose non scherzano ed hanno già ottenuto risultati concreti contro le pratiche bislacche degli editori scientifici con azioni simili in passato. Spero che anche questa campagna produca risultati. Spero sia di in interesse non solo ad Emanuele :-) Ciao, Daniele

[VIDEO] Ecco perché il voto elettronico è (ANCORA) una pessima idea.
by Matteo G.P. Flora June 8, 2021

June 8, 2021

Negli ultimi anni tanto è stato fatto sulla divulgazione delle problematiche del #VotoElettronico, e se ne è parlato spesso, raccontando i come e i perché sia una pessima idea: le contro-argomentazioni sono sempre state le stesse, di base espresse da persone che pensano di avere una soluzione “innovativa” ad un problema che le massime menti informatiche al mondo vedono come l’apocalisse. E no, nessuna ce le ha, le soluzioni alternative, perché si tratta di un problema complesso nel crocevia tra tecnologia e diritti. Ciò nonostante non passa settimana in cui qualcuno non tiri fuori dal cappello l'ennesimo "voto su tecnologia XXX" e ogni settimana qualcuno chiede agli esperti le stesse cose: le cose devono essere cambiate ormai, giusto? Nel senso, c’è questa nuova idea, questa nuova tecnologia, hanno trovato questa nuova cosa e studio, hanno finanziato questa piattaforma, ora aiuterà sicuramente! Vero, che il voto elettronico adesso è dietro l'angolo? No, non lo è. No, davvero. E non lo sarà probabilmente nello spazio di altri 100 anni, a meno di rivoluzioni copernicane. Prendendo le fila dal celeberrimo video di Tom Scott “Why Electronic Voting Is Still A Bad Idea” e con l'aiuto di stimati professionisti ed amici (anche qui in lista) come Fabio Pietrosanti, Maurizio Lana, Stefano Quintarelli, Stefano Zanero, Davide Del Monte, Stefano Fratepietro che hanno rivisto i testi oggi ho un video per voi, abbiamo pensato di affrontare e spiegare l’argomento una volta per tutte. Ecco perché il voto elettronico è ANCORA una pessima idea. https://youtu.be/GvPZe41S_as -- Per i curiosi di una sola parte: 00:00 <https://www.youtube.com/watch?v=GvPZe41S_as&t=0s> - Introduzione: ancora una pessima idea... 01:47 <https://www.youtube.com/watch?v=GvPZe41S_as&t=107s> - I requisiti di voto anonimo e segreto 04:30 <https://www.youtube.com/watch?v=GvPZe41S_as&t=270s> - Il requisito di fiducia e trasparenza 06:39 <https://www.youtube.com/watch?v=GvPZe41S_as&t=399s> - Gli attacchi al voto cartaceo e la scalabilità 08:58 <https://www.youtube.com/watch?v=GvPZe41S_as&t=538s> - La questione degli attacchi che scalano 11:25 <https://www.youtube.com/watch?v=GvPZe41S_as&t=685s> - Macchine di voto, Open Source, fiducia 13:52 <https://www.youtube.com/watch?v=GvPZe41S_as&t=832s> - Macchine di voto e checksum e ancora fiducia 17:37 <https://www.youtube.com/watch?v=GvPZe41S_as&t=1057s> - Il trasporto dei voti 20:17 <https://www.youtube.com/watch?v=GvPZe41S_as&t=1217s> - Il server centrale e la "fiducia ultima" 22:44 <https://www.youtube.com/watch?v=GvPZe41S_as&t=1364s> - L'attacco alla Fiducia (Trump, Biden e Leonardo...) 24:54 <https://www.youtube.com/watch?v=GvPZe41S_as&t=1494s> - E cosa ci dici del voto "online"? 27:05 <https://www.youtube.com/watch?v=GvPZe41S_as&t=1625s> - Voto elettronico in Estonia e Germania 31:35 <https://www.youtube.com/watch?v=GvPZe41S_as&t=1895s> - ...e la BlockChain? 31:53 <https://www.youtube.com/watch?v=GvPZe41S_as&t=1913s> - Conclusioni e ringraziamenti -- *Matteo G.P.

The Dark Side of Congo’s Cobalt Rush | The New Yorker
by Alberto Cammozzo June 8, 2021

June 8, 2021

<https://www.newyorker.com/magazine/2021/05/31/the-dark-side-of-congos-cobal…> [...] In Kolwezi, children as young as three learn to pick out the purest ore from rock slabs. Soon enough, they are lugging ore for adult creuseurs. Teen-age boys often work perilous shifts navigating rickety shafts. Near large mines, the prostitution of women and young girls is pervasive. Other women wash raw mining material, which is often full of toxic metals and, in some cases, mildly radioactive. If a pregnant woman works with such heavy metals as cobalt, it can increase her chances of having a stillbirth or a child with birth defects. According to a recent study in The Lancet, women in southern Congo “had metal concentrations that are among the highest ever reported for pregnant women.” The study also found a strong link between fathers who worked with mining chemicals and fetal abnormalities in their children, noting that “paternal occupational mining exposure was the factor most strongly associated with birth defects.” This year, cobalt prices have jumped some forty per cent, to more than twenty dollars a pound. The lure of mineral riches in a country as poor as Congo provides irresistible temptation for politicians and officials to steal and cheat. Soldiers who have been posted to Kolwezi during periods of unrest have been known to lay down their Kalashnikovs at night and enter the mines. At a meeting of investors in 2019, Simon Tuma Waku, then the president of the Chamber of Mines in Congo, used the language of a gold rush: “Cobalt—it makes you dream.” After Kasulo’s mayor fled, many residents began tearing away at the ground beneath them. Some wealthier locals hired creuseurs to dig under their houses, with an agreement to split the profits. Two teams of creuseurs could each work twelve-hour shifts, chipping at the rock with hammers and chisels. A pastor and his congregation began digging under their church, stopping only for Sunday services. By the end of 2014, two thousand creuseurs were working in the neighborhood, with little regulation. Kajumba and his coöperative soon joined in the hunt for minerals. One man on Kajumba’s team, Yannick Mputu, remembers this period as “the good times.” He told me, “There was a lot of money, and everybody was able to make some. The minerals were close to the surface, and they could be mined without digging deep holes.” But the conditions quickly became dangerous. Not long after the mayor formally prohibited excavating for minerals, a mine shaft collapsed, killing five miners. Still, people kept digging, and by the time researchers for Amnesty International visited, less than a year after the discovery of cobalt in Kasulo, some of the holes made by creuseurs were a hundred feet deep. Once diggers reached seams of ore, they followed the mineral through the soil, often without building supports for their tunnels. As Murray Hitzman, the former U.S.G.S. scientist, pointed out, the heterogenite closest to the surface often contains the least cobalt, because of weathering. Creuseurs in Kasulo were risking their lives to obtain some of the worst ore.[...]

Ban biometric surveillance: civil society demands outright prohibitions on public and private use
by Enrico Nardelli June 7, 2021

June 7, 2021

Access Now and over 175 civil society organizations, activists, and researchers from across the globe are calling for a ban on uses of facial recognition and remote biometric recognition that enable mass and discriminatory targeted surveillance. Civil society organizations, activists, researchers, and technologists are drawing a line in the sand and demanding legal prohibitions on the use of these tools in publicly accessible spaces, whether by governments, law enforcement, or private actors. “Facial recognition and related biometric recognition technologies have no place in public. These technologies track and profile people as they go about their daily lives, treating them as suspects and creating dangerous incentives for overuse and discrimination,” said Daniel Leufer, Europe Policy Analyst at Access Now. “They need to be banned here and now.” These surveillance tools have the capacity to identify, follow, single out, profile, and track people everywhere they go, undermining human rights and civil liberties. They are an attack on privacy and data protection, exacerbate inequality and discrimination, and have the potential to muzzle freedom of expression and assembly — further solidifying the criminalization of protest. ... continua qua https://www.accessnow.org/civil-society-ban-biometric-surveillance/ -- EN ===================================================================== Prof. Enrico Nardelli Dipartimento di Matematica - Universita' di Roma "Tor Vergata" Via della Ricerca Scientifica snc - 00133 Roma tel: +39 06 7259.4204 fax: +39 06 7259.4699 mobile: +39 335 590.2331 e-mail: nardelli(a)mat.uniroma2.it home page: http://www.mat.uniroma2.it/~nardelli blog: http://www.ilfattoquotidiano.it/blog/enardelli/ http://link-and-think.blogspot.it/ ===================================================================== --

Re: [nexa] Is Online Test-Monitoring Here to Stay?
by maurizio lana June 7, 2021

June 7, 2021

buongiorno, insegno all'università, e trovo che i software di proctoring siano deprecabili. non sto a raccontare qui a voi come e perché lo sono. la questione vera sono gli esami e il loro contenuto. se la prova d'esame verifica conoscenze nozionistiche è ovvio che si debba (?) ricorrere ai software di proctoring. ma un esame universitario non può continuare ad usare il medesimo modello concettuale dell'interrogazione alla scuola primaria. qui si vede che ai rivolgimenti portati dalla pandemia si può rispondere restando accozzati a quello che si faceva prima, oppure si può farne occasione e stimolo per rinnovare, cambiare, migliorare: come possiamo eliminare dagli esami la componente di nozionismo per centrarli sempre più, tutti, sulla verifica di competenze?
