Dopo i miei dubbi su Ubuntu 20, ho installato a casa una distribuzione Debian 11 e riporto qui le mie prime impressioni."Ora bevo la pozione magica, divento Asterix e ti picchio!"
Debian è una distribuzione molto solida, ma non avevo mai avuto modo di provarla in modo continuativo: ai tempi dell’università preferii Slackware e RedHat.

Slackware was my first real distro in 1995 and I am happy it is still alive and kicking. It was a floppy disk based distribution. So you end up filling about 20 disks (!) of 1.44MB to install and boot Linux on your old i386 with 1MB of RAM and 40MB of HardDisk. After
some upgrade I finally got a PC with 8MB RAM and 500MB hard disk (and yes, it was a lot of space for that times!).

C’è un bellissimo pezzo di Luca Sofri, che ci fa riflettere sulla mirabolante idea della
democrazia diretta, tanto cara al M5S, e della cui zoippicante implementazione sofware noi siamo stati dubbiosi in tempi non sospetti.Riporto dal pezzo di Sofri, che a sua volta cita due importantissimi quotidiani, dei virgolettati da una chat interna del M5S, che sono con tutta probabilità veri, perché provienenti da moltissime fonti diverse con il medesimo significato

La cosa che ho sempre apprezzato dei computer Commodore era la loro immediatezza. Grazie ai caratteri grafici impressi sui tasti, era possibile scrivere piccoli e gradevoli programmi con poco sforzo.

In questo articolo vi mostro come fare delle piccole animazioni , usando il Commodore 16.

Nel 1984, dopo il successo del C/64, la Commodore lanciò sul mercato il Plus4 ed il Commdore16, due macchine quasi identiche che si differenziavano per il quantitativo di RAM a bordo e per la dotazione del software in ROM.
Il Commodore 16 idealmente doveva soppiantare il Vic20, aveva 16 KB di RAM e il Basic 3.5, notevolmente più comodo del BasicV2 della coppia Vic20, C/64. La CPU era anche il 75% più veloce rispetto ai predecessori, ma il chip grafico era incompatibile con il C/64 e il C/16 non disponeva né di Sprite né della profondità sonora del SID:
