"Nonflood flooding is occurring and minor flooding is forecast" -- NWS bulletin
pondering chorded keyboards
Thought of a way to squeeze both a 64 byte previous message hash and a 64 byte signature into a message, using only 64 bytes.
Just leave out the previous message hash from the serialized message, but include it in the data that's signed. When verifying the signature, try recently seen messages's hashes as the previous message until finding the one that makes the signature verify. (Conveniently, Ed25519 verifies very fast and can do batch verifications.)
Playing with scuttlebutt for the first time today. Very impressive.
Very appropriately, I met one of its developers in a pub IRL.

I'm on several pubs, my impression is that at least the public ssb network is fairly well connected and it should not matter even if you ended up on different ones, I'd still see you.
It's a 3 hop gossip network, and pubs count as hops, so
me -- mypub -- yourpub -- youworks because 3 hops. Assuming our pubs are connected, and the pubs I can see are all interconnected.
Either I'm finally over the 48 hour flu, or finally found the right meds to mask the symptoms. Anyway, I can think again.
(Modern games have this strange habit of tracking how much time you wasted with them, so I know I played Thimbleweed park for 11 hours yesterday. I even remember most of it, but I was clearly not compos mentis.)

Sun is down, satellite internet is still up! Turns out there are few things more annoying than losing internet when the sun goes behind some object.
The DROK DC-DC booster solved it. I had originally planned to use it instead of the DC power supply, but that led to very loud coil whine not suitable for use. Don't understand why. Using the DROK to power an inverter, which then gets converted back to DC is not efficient, but at least it works. (And I tuned it so the inverter never spins its fan, so perhaps it's not super innefficient.)
Probably will switch to a better inverter that can handle lower voltages on its own.
Has Sumana Harihareswara invented a new form of presentation? her LibrePlanet keynote was a menu of 35 lightening talks, with the audience selecting between them.
Planning to rewatch this, it went so fast and there was so much in there. Also, got a little bit busy with politicking that resulted in the final pick of #15.
She could give this talk a dozen times and it would be a dozen different experiences I'll bet.

Hands-on Reproducible and Scalable Brain Imaging Analysis with Nipype note 3
Science, schmience.. it's all software development and IT. Not really news.
(Getting the feeling that scientists seem to have more fun than software developers on average. For example, I am sitting across the table from Arno, http://elloradaily.info/'s dad, a hilarious guy.)

When you have a whole workshop of people pulling the same container images, wifi gets overloaded. These systems need local LAN p2p sharing.

Docker is not super well suited for use in reproducing scientific research (command line complexity; need to GC old sessions etc), but they are using it anyway. The singularity container system may be better suited, won't be surprising if scientific communities switch to it.

awesome Libreplanet day
Some great taks and discussions today!
Meanwhile, backstage, I hung out a bit with science fiction author Cory Doctorow in the green room.
And had dinner with one of the founders of Can Masdeu, the leper hospital turned squat in Barcelona.
