avva- О телевизорах. У меня есть такие знакомые ;-) А у вас?
- Оказывается, волосы и ногти всё же не растут после смерти.
- Удивительная и очень смешная история для программистов и сисадминов.
- Статья из двух частей. Первая - о том, как в 60-х и 70-х годах кварки из красивой теоретической идеи превратились в признанную часть реального мира. Вторая - об опасности тенденции в современной физике пренебрегать формулированием эмпирически проверяемых утверждений (testable hypotheses); с явным намёком на теорию струн.

Date: 2003-10-30 08:26 pm (UTC)The funniest use of `ping' to date was described in January 1991 by Steve Hayman on the Usenet group comp.sys.next. He was trying to isolate a faulty cable segment on a TCP/IP Ethernet hooked up to a NeXT machine, and got tired of having to run back to his console after each cabling tweak to see if the ping packets were getting through. So he used the sound-recording feature on the NeXT, then wrote a script that repeatedly invoked ping(8), listened for an echo, and played back the recording on each returned packet. Result? A program that caused the machine to repeat, over and over, "Ping ... ping ... ping ..." as long as the network was up. He turned the volume to maximum, ferreted through the building with one ear cocked, and found a faulty tee connector in no time.
