Arriva il fratello maggiore di Arduino?

raspberry

 

Si chiama Raspberry Pi ed è dotato di tutto quello che si può desiderare da una piattaforma embedded: processore ARM11 da 700MHz, 256MB di RAM, scheda di rete, audio, uscita video composito e hdmi, lettore di SD card e un interfaccia GPIO. Il tutto ad un costo che varia da 25$ a 35$ a dipendenza della variante scelta (variante A: 1 sola USB; variante B: 2 USB e ethernet).

FLL 2011: 6 team SAM al torneo di robotica

Sono ben sei i team targati SAM che si stanno preparando per partecipare al torneo di robotica First Lego League che si terrà il 26 novembre a Locarno. Quattro team apartengono dalla sezione informatica mentre altri due sono formati da alunni provenienti rispettivamente dalla sezione del disegno e da quella dell'elettronica.

0.999... = 1 ?

Un quesito interessante da proporre al vostro docente di matematica:

Ma 0.999... corrisponde a 1 oppure sono due numeri reali diversi?  Se sono uguali allora ogni volta che in un'espressione matematica troviamo il valore periodico 0.999... lo possiamo tranquillamente sostituire con 1. Giusto?

Ma come dimostrare che 0.999... è uguale a 1?

Proviamo a fare dei semplici ragionamenti matematici partendo dall'uguaglianza (o equazione) 1 = 1:

Un numero intero diviso per se stesso da sempre uno, quindi possiamo scrivere ad esempio:

1 = 9/9

Se 1 = 9/9, allora possiamo anche scrivere:

1 = 9 * 1/9

Ma 1/9 corrisponde a 0.111...  quindi

1 = 9 * 0.111...

E di conseguenza

1 = 0.999...

;-)

Truffa alla cinese

Recentemente abbiamo ricevuto dei messaggi di posta elettronica da parte di una sedicente azienda di registrazione di nomi di dominio cinese. Ecco un'estratto del messaggio:

"...Dear CFO / CIO,

 
We are a professional intellectual property rights consultant organization based in HongKong. Now, we have an important issue to confirm with you.
 
1. On Aug 22, 2011, one company named Cowny Investment LLC applied for the following Domain Names with our organization.
 
...
 
2. During our preliminary investigation, we found that these Domain Names' keyword is identical with your Trademark, this is why we inform you.
 
3. I wonder whether did you consigned Cowny Investment LLC to register these Domain Names with us?
 
4. If you do not have any relationship with this applicant, we assume that they have other purposes to obtain these Domain Names.
 
Currently, We have already postponed this company's application due to the seriousness of this issue. In order to avoid the vicious domain name grab, please let the relevant principal make a confirmation with me ASAP.
Thanks & Regards,
 
Angus Luo

 

..."

Se ricevete messaggi simili non rispondete, si tratta di un tentativo di truffa...
