Xen DNA TShirt

I got this TShirt at FOSDEM, I was told that it means something .

First here is all of the text from the tshirt, which should make the page more discoverable:

Forging the 
DNA of the Cloud

AGTCTACTCAGCCGTACTTCATCGACTTAGCGTTGTCTCAGC
GCTTGTCACGTCCTGCTCGTCAGCTAGCGTCTAAGCTACCTC
ACTAGCTGTGCTAGCTAGCGTCTAAGCTCAATCTGTGATTAC

These three strings are a bit unweildly to work with, lets break them down into groups of three.

AGT CTA CTC AGC CGT ACT TCA TCG ACT TAG CGT TGT CTC AGC
GCT TGT CAC GTC CTG CTC GTC AGC TAG CGT CTA AGC TAC CTC
ACT AGC TGT GCT AGC TAG CGT CTA AGC TCA ATC TGT GAT TAC

Now to wikipedia to get a DNA Codon Table to refer to:

I poked at this for ages, I wondered if I had need to the take the codons in as they are written. A column at a time. But even looking at that, there was nothing obvious about the codon sequence.

After a while I started searching for subsequences from the string. This didn't help at all, but one page on google had a related search for ['dna message translator'][3]. Annoyingly I fed in this string:

AGTCTACTCAGCCGTACTTCATCGACTTAGCGTTGTCTCAGCGCTTGTCACGTCCTGCTCGTCAGCTAGCGTCTAAGCTACCTCACTAGCTGTGCTAGCTAGCGTCTAAGCTCAATCTGTGATTAC

And got the result:

Trains Home

Long journey back from FOSDEM, a train to Paris, train to the Airport and a hop through Amsterdam before making it home.

FOSDEM is Done

FOSDEM is done! I want to start writing about the things I saw, but my phone still won't speak to my laptop. Tomorrow should be more differenter, once the travel is done I will have access to sane computing.


It is Sunday, so that makes seven days of writing .

FOSDEM 2017

I did my talks today, there is video coming, but I am told the audio is out of sync. My hotel doesn't seem to be up to doing streaming video so I haven't even tried.

Here are the slides:

Which should be clickable, but I can't figure out how to trick my site to do it

FOSDEM Prep

Tomorrow, I am presenting at FOSDEM . Somehow I have gotten roped into doing two talks at almost the same time.

At 1555, I will present QoS Challenges for Real Time Traffic in the Real Time Communications devroom. I am pretty certain I am going to explain what the hell QoS in the internet is, some of the benefit you might see and how to do any of this with NEAT. The recent measurements we have been doing suggest that QoS shouldn't be a deal breaker for any connection, great news, but it doesn't make much of a discussion.

At 1630, I will present Transport Evolution on top of the BSD's in the BSD devroom. The two talks are in the same building, but 15 minutes is a bit tighter than I would have liked. This talk will be about the problems faced in making the internet better and how NEAT will help.

I know the BSD devroom will be recorded, but not streamed. I haven't heard anything about the RTC rooms video setup. If you are around for FOSDEM you should drop by and ask me difficult questions. If not I will take them over email.
