Writing really small TCP/IP stacks
Adam Dunkels, author of Contiki and the uIP embedded TCP/IP stack, held a talk at NUCCC 2005 this weekend about writing really small TCP/IP stacks and making them withstand slashdottings. Adam's various TCP/IP stacks have been both slashdotted and osnewsed several times. Nice quote from the talk: "Great hacks are the diamonds of computer science: 'Useless', yet priceless!".
