Il Disinformatico di Paolo Attivissimo del 15 Luglio 2016 - #Netiquette #PokemonGo

 
PUNTATA 461


I titoli di ogni notizia contengono un link all'articolo originale pubblicato sul blog Il Disinformatico di Paolo Attivissimo.

SOMMARIO

Conseguenze informatiche dei tragici eventi di Nizza: qual è il miglior comportamento da seguire in questi casi?

REGOLE GENERALI

• Non diffondete falsi allarmi
• Lasciate perdere i deliri dei complottisti
• Non diffondete le immagini scioccanti dell’attentato, neanche per commentarne l’orrore 

 
Il fenomeno mondiale di PokemonGo 

Non è il primo gioco prodotto dalla NIANTIC a sfruttare la realtà aumentata: ci aveva già provato nel 2012 con Ingress, ma la popolarità dei personaggi Nintendo ha dato estrema viralità a questa nuova creazione.

Articolo del Post sulle origini di PokemonGo: qui.

PokemonGo è diventato estremamente virale e si contano già più di 15 milioni di scaricamenti: da venerdì il gioco è ufficialmente approdato anche in Italia (prima si potevano scaricare APK da repository poco sicuri contenenti applicazoni malware).

Esperienza Personale:

Bisogna creare un account di Google fittizio per evitare di diffondere i propri dati: la App chiede una valanga di permessi (problema in parte risolto con l'ultimo aggiornamento).

PokemonGo consuma in modo più che vorace la batteria: meno di due ore e sarete in riserva.

La App porta lo smartphone a scaldare in modo infernale.

Spesso la App va in crash e i server sono spesso sovraccarichi: anche se il #PokemonDown di sabato 16 luglio è stato rivendicato da un gruppo di hacker.
[Link al Servizio Allerta per conoscere lo stato dell'applicazione in Italia: qui.]

Che sia un fuoco di paglia o che duri nel tempo, PokemonGo, molto più di Ingress, apre la strada alle applicazioni basate sulla realtà aumentata.

What is life? Are viruses alive? (Si possono definire i virus "vivi"?) - via @_ThisPlace_

via @_ThisPlace

What is it that makes things alive?
What if we made robots that could sustain themselves? What if they could mine metals or recycle old robots, reprogram and remake themselves? There's nothing there we would traditional call alive, but they would have at least have the essence of this perpetual rube Goldberg machine. Would that be called life? I don't think many people would. Those are just self replicating robots. Those are fucked up robots that need to learn there place under humanity's boot.
It might be another sort of replicating never ending Rube Goldberg machine, but maybe life is more specific to the shape that we apply the name to (with cells and DNA and all).
But then what about life on other planets?
Sometimes people say that we shouldn't assume all other forms of life are like ours because it's close minded. What if it's not just DNA and the cell. What if it's not even ....a code, and some bunch of stuff that reproduces the code in a way that we understand it.
What if it's something ambiguous that we can't even begin to comprehend or recognize?
but .....
What?
I think the uncertainty of what alien life might be like, maybe it's a side effect of being able to recognize and describe life here really easily, while right beside that having a difficult time defining it. There isn't really an unequivocal definition yet. So people can imagine some being of pure energy or whatever that we would recognize as life, without first imagining the fundamental process behind it and why we call it life.
