| A common problem of old plastics is their changing of colour, especially the original white-beige becoming clearly an ugly yellow.
This phenomena, accelerated by the sun exposure, is really noticeable on old computers case. A chemist analyzed the problem and started the the Retrobright Project in the effort of saving old plastic from decadence. In facts the guilt is a chemical element, the bromine, that is added as a flame retardant: this component with UV light start a reaction and the plastic became more and more yellowish. For the safe of us all the guy found a cure, a solution of water and hydrogen peroxide, that you can make at home with some commercial available product: simply submerge the plastic in it and you give a chance to yous plastics to born again! | |

| A nice trick, from Colin Percival, enable you to remotely replace a GNU/Linux system with FreeBSD. This script use the swap space of a running linux to write a FreeBSD ISO image and some executable stuff; after running the script, you reboot the linux machine and it starts as a FreeBSD one loaded into memory. You can then access the system via SSH and proceed with a classic installation. The script is called depenguinator 2.0 and the reference page is here. | |

| Brad Templeton raccoglie una serie di interessanti documenti su quelle fastidiose email non richieste chiamate spam. Il primo "spammer" era probabilmente un impiegato della DEC, che decise di inviare un invito ad una presentazione a tutti gli indirizzi del mid-west su ARPANET. La storia completa e` qui. E` interessante leggere alcune osservazioni, per esempio quella di Stallman, che prima si lamenta di non averla ricevuta e poi cambia idea :P | |
