Hi. I am starting a project that will be a program to learn. My idea is use
every single function of Cocoa framework to show any behavior. For newbie
like me, same time is difficult read the Apple docs and know what the
function exact do, and what object I have to use in same cases.

Ok, but firstly I have to chose a name. First I thought use “Cocoa with
hate”, a joke because exist the site “Cocoa with love” (I am not hate Cocoa,
not all the time 😛 ). But I thought this a bit bad.

My new idea was use the disease of cocoa, namely “witch’s broom”. Here in
Brazil, this is a pest and isn’t a easy to prevent. There are two meanings
in this name. First is the joke because we have to “fight” with cocoa to
learn. The disease itself is a (don’t know the correct english name for
this) huddle, congeries… of wood and leaves that look like a witch’s
broom. <http://www.sierrapotomac.org/W_Needham/WitchesBroom_R041220.htm> And
this will be the program, a lot of thing in a small place.

Witch’s broom isn’t disease only for cocoa. So “Witch’s broom” itself isn’t
a good name for a program. My ideas was:

– Cocoa Witch’s Broom (Do this the most correct?)
– Cocoa Witches Broom  (Isn’t it the correct?)
– Cocoa’s With Broom (With Broom of cocoa)
– Cocoa’s Witch’s Broom
– Witch’s Broom of Cocoa
– Witches Broom of Cocoa

For you, English speaker, what is the most correct, The first is not the
correct? Witches is the plural? Give-me a idea for this.
_______________________________________________

I’m not sure creating a program to use every method in Cocoa is such a great idea. What you should probably do instead is pick a small simple idea and implement it. Perhaps you can make an app that lists the native trees of Brazil and their diseases. 🙂

trovare ip
_____________________________________________________________________

Come faccio a trovare tutti gli ip associati ad un dominio ?
Per esempio grossi “servizi” , google, facebook, ecc, hanno associati intere classi.
Tralasciando l’idea di fare centinaia di “host nome”/”nslookup nome”, come posso fare ??
Walter

dig ti da un dettaglio di tutti gli IP associati al nome:

$ dig +short www.google.com
www.l.google.com.
74.125.39.147
74.125.39.106
74.125.39.105
74.125.39.104
74.125.39.99
74.125.39.103

Ma anche nslookup e host lo fanno, perché dovresti fare centinaia di questi comandi?

Per esempio grossi “servizi” , google, facebook, ecc, hanno associati intere classi.
Spesso un record A ha tanti valori per fare DNS round robin come hanno evidenziato RaSca e Innocenzo.

La cosa interessante da cui credo nasca la tua domanda è che circa ogni minuto e mezzo www.facebook.com cambia record A andando anche su autonomous systems diversi:

www.facebook.com A 66.220.156.18
www.facebook.com A 69.63.190.10
www.facebook.com A 69.63.190.18
www.facebook.com A 66.220.156.32

La cosa che non mi spiego č perchč nessuno dei DNS autoritativi di facebook.com conosca l’A di www.facebook.com:
$ hostx www.facebook.com ns1.facebook.com
www.facebook.com A record currently not present at ns1.facebook.com

Se qualcuno ha idee di come funziona www.facebook.com si faccia avanti 😉

Comuneuq puoi trovare informazioni interessanti sulla rete facendo il whois sull’IP:

$ whois `hostx facebook.com | awk ‘{ print $3 }’ | head -n1`

NetRange:       69.63.176.0 – 69.63.191.255
CIDR:           69.63.176.0/20
OriginAS:       AS32934
NetName:        TFBNET2

$ whois 66.220.156.18

NetRange:       66.220.144.0 – 66.220.159.255
CIDR:           66.220.144.0/20
OriginAS:       AS32934
NetName:        TFBNET3
