free party (thing)

2003-10-31T21:19:35Z

Mostly found in the UK, a free party is an illegal, outdoor rave, held in fields, under motorway bridges, etc. The free party culture is heavily influenced by Jamaican Soundsystems, and the format is roughly the same as in JA.

Usually the party crew (the organisers) will arrive at the site just after dark, and set up. At about 11, we record directions on a mobile phone voice mail, and people phone the number for directions. This keeps the police from getting to the party too soon. Although they have the power to shut down parties, they will usually not try once there are a hundred or so people.

For most people who attend free parties, they are part of a good night out, without the hassle of bouncers and dress codes. For some of us, however, the party follows several hours of running from police helicopters, setting up the rig, and hoping someone will turn up. A decent (10-20 KW) system is worth tens of thousands, and the owners are usually…

iptables (thing)

The MANGLE table is used to alter certain properties of packets as they traverse the firewall. You can change the TOS (type of service), TTL (time to live), and MARK .

The TOS is used by (some) routers to make routing decisions, as is the MARK. They are useful for internal routing on a large network, and various esoteric rituals. However, these properties are poorly implemented on the internet at large, so these fieldsare little use for traffic bound for the intraweb.

The only example I have seen for MANGLEing the TTL of packets is to disguise multiple computers sharing an internet connection, althoght there are doubtless many subtle and confusing applications.

(This really ought to be part of JCCyC's w/u above, 'cos he explains iptables better than I could. Just filling a gap :-)

TTL (idea)

Also transistor-transistor logic . One of several types of IC (Integrated Circuit). TTL logic gates are found in most simple Dual In-line Package chips.

Other types include resistor-transistor logic (RTL), diode-transistor logic (DTL), emitter coupled logic (ECL).

TTL circuits were used in Texas Instruments' TTl74 IC series in 1962, and were used into the 90's, when the +5v rail proved too inefficient for modern computer systems. They are still used in simple, DIL chips for teaching/simple logic purposes.

Evelyn Waugh (person)

Evelyn Waugh was born in Hampstead in 1903, son of Arthur Waugh, and brother of Alec Waugh, both novelists. He was educated at Lancing and read Modern History at Hertford College Oxford.

In 1928 he wrote Decline and Fall a satire of the preparatory school industry, followed in 1930 by Vile Bodies, another biting satire, this time of the pre-war smart set, the "bright young things." (Recently filmified under that title)

Before the Second World War, Waugh travelled extensively, mostly in the "uncivilised" world - Africa, South America, and the Middle East. His books of this period are full of minute - but impersonal - observations of people and their behaviour, and make fascinating reading.

During the War, he commisioned in the Royal Marines, and served in the Middle East and Yugoslavia. This experience led to Put Out More Flags, and the Sword of Honour trilogy, which are all set in and around WW2, and are much…
