Kali linux/Debian: Failed to copy file from CD-ROM. Retry?

1. Create a bootable USB image with Rufus in Windows 10 and make sure you select DD image and NOT ISO image, when you select DD it wont see the ISO file because it is looking for a different file type, just select "All files" then select the correct ISO file. 2. Boot from the USB and choose Graphic Install. 3. Make sure you connect to the Internet during the install using Ethernet or wifi and allow the package manager to setup correctly with mirrors etc. SOURCE

Sonoff doesn't connect to WiFi after the password changed

Today I change the password of my WiFi network, maintaining the same SSID name (or WiFi Name). After this I made again the pairing of my Sonoffs around the house... but can't connect! The problem is that if you change the password of your wifi and you still use the same name, the Sonoff go in trouble. But I found a tricky for resolve this: - create a new wifi network: example SSID: wifi1 PASSWORD: wifi11234 - put the Sonoff in the "Compatible Pairing Mode (AP)" - enter the wifi1 wifi information in the eWelink App - and the Sonoff will work Now do again the same procedure with other wifi name (example wifi2...) After this, put the official name and password of the WiFi and do again the pairing procedure and now the Sonoff will work with your WiFi

iPhone, Vodafone: non partono gli sms

Passo da TIM a Vodafone... non partono gli sms! In poche parole si deve riconfigurare, o meglio ripristinare, il cosiddetto "centro servizi sms" o qualcosa del genere. L'operatore Vodafone, Daniel, veramente bravo nel guidarmi. Apri l'app TELEFONO Nel tastierino digita le seguenti cifre *5005*7672*+393492000200# Premi l'icona verde di chiamata Ti compare un messaggio in inglese, premi ok Prova ad inviare un sms Funziona Prego  Questa operazione è valida anche per gli altri operatori, ma il numero +393492000200 deve essere sostituito con quello dell'operatore che usate!

Quante volte deve girare un ingranaggio affinché tutti si riallineano come prima?

Image
Sembrerà assurdo, ore ed ore di calcoli ed alla fine grazie ad una slide del liceo in cui c'è Paperino ho trovato la soluzione! Abbiamo realizzato con un amico una parete con questi ingranaggi e volevamo sapere: quante volte deve girare l'ingranaggio A affinché tutti gli ingranaggi si riallineano come da foto? Un momento del giro di... ingranaggi Ecco la soluzione: calcolate il minimo comune multiplo  del numero dei denti degli ingranaggi mcm(9,15,5,11,11,13,6) = 12.870  una volta trovato il mcm, dovete dividere 12.870 per il numero dei denti dell'ingranaggio desiderato. Nel nostro caso l'ingranaggio A ha 11 denti, quindi  12870/11 = 1.170  l'ingranaggio A dovrà girare 1170 volte! Lo abbiamo fatto... ed è così! Pazzesco Appunti finali
