Meeting #1 report + audio-und-slideware of Hans’ talk

February 9, 2011

So we had a very lovely evening yesterday at the ZSLUG revampening. It must have been the FPGA raffle, because the attendance was a bit above expected. Around 25 people dropped by, from as far as Munchen and Lisbon. Far more people than the catering department had dimensioned for.

We got both Hans’ slideware and recorded his talk, which was about his rocky road towards trying and put a big ol’ Lisp machine on an FPGA.

He brought up some cool stuff. Listen for yourself:
MP3: here!
Slideware: here!

00.00 -> FPGA introduction
Start at slide 3: The quest for a new Lisp machine

16.22 -> Hans’s personal dabblings
Start at slide 20: From CADR through SECD to rekonstrukt

31.50 -> Questions (not always clear voices due to microphone proximity, or rather lack thereof)

Then it was FPGA give-away time. A Xilinx board if memory serves well. The green board from the slides. We managed to catch several participants on cheating as they scribbled their name twice or trice on little white pieces of paper, but in the end it was Joshi who got his name drawn out of the soup-plate. Another hacker set up for boundry-diffusion greatness.

After the excitement settled down, Luke let loose upon an unexpected public TCP diagrams explaining the difference between TCP behaviour in fixed-line networks vs mobile networks. Walking us in detail back and forth between client and server, and pulling us into the murder mystery of what could have happened with those lost tcp packets (think I just stole that analogy from the bufferbloat hubbub of late). Because it is a fascinating world within the two lines between client and server. One can think up a thousand scenario’s on what might have gone wrong.

We didn’t make it that late though. Tummies were rumbling, and we managed to get the last scraps from the kitchen of the tapas place around the corner, and left nodding politely as they turned the hard bright lights on us.

Thanks people for a great night! Hope to see you all soon.

    Hi guys

    As You were talking about these FPGA and other weird stuffs on Friday, this might be of interest for You:

    Keep on lisping and hacking, good luck

    is there audio of Luke’s mobile tcp presentation, too? or at least copies of his diagrams?
