Backup in rete pratico e veloce con FTP – 2

Zarrelli il domenica, 24 Febbraio, 2008

Dopo quasi, ahem, un anno di stasi, vediamo di chiudere l’agomento inziato con il primo post Backup in rete pratico e veloce con FTP -1, passando alla parte più “operativa”.

backup_tape.jpg

Vediamo, qui di seguito, un semplice shell script che si occupa di creare un backup all’interno di un file tgz, che avrà come prefisso la data del giorno di archiviazione. Creato il file, provvederà a trasferirlo via ftp sulla macchina d’appoggio, e infine cancellerà l’archivio il cui suffisso sarà costituito dalla data odierna – 15 giorni.

Prima di procedere, però, un avvertimento: questo post è decisamente lungo e, per qualche verso, anche noioso.

Non dite che non vi avevo avvisati 🙂

Ma chi me l´ha fatto fare?

Mai visto i RIS su Canale 5.

Questa sera mentre ¨zappo¨ per i canali, vedo questi CSI e noantri che mettono le mani su un portatile recuperato sulla scena di un qualche delitto.

Il tecnico informatico, con espressione seria, quasi contrita afferma che gli hard disk dei portatili ¨ormai¨, vengono costruiti per resistere al calore. Oh, beh, almeno mettessero i fornitori nei titoli di coda…

Non contento, chiede al poliziotto che gli sta accanto di passargli i terminali. Ahem, in pratica i puntali di un tester elettrico.

Attacca i puntali in due punti del disco e inizia a…boh…scaricare dati?

All´inizio ho scorto un grafico a torta, poi il salvaschermo Matrix. Avete presente quello con stringhe alfanumeriche verdi su sfondo nero che calano dall´alto.

Alle rimostranze del poliziotto, che si lamenta nel vedere solo zero e uno, il tecnico, finalmente, spavaldo e gagliardo, chiede solo un´ora per ¨tradurre¨ gli zero e gli uno.

Questa gente mi toglierá il lavoro.

O forse tormenterá il mio buon senso…

Eeepc: ecco cosa dice lshw

Fontubuntu

Zarrelli il giovedì, 3 Gennaio, 2008

Vi interessa avere un set di font simili a quelli utilizzati per il logo di Ubuntu? Date un’occhiata al blog di Christian Robertson e scaricate l’archivio contenete i sorgenti in FontLab e gli script utilizzabili per ricavarne gli OTF e TTF.

 

E come dice l’autore…

 

As far as I’m concerned anyone can do anything they want with it. I haven’t wasted too many brain cycles reading all the licenses for creative works…
