Hey everyone. Check out our next 1BitSquared CrowdSupply campaign. We will be making @whitequark’s Glasgow Interface Explorer. Sign up to get notified when it launches and take advantage of those sweet early bird tiers. ;) https://www.crowdsupply.com/1bitsquared/glasgow
"Bone has traditionally been regarded as a static structural organ that supports movement of the body and protects the internal organs. However, evidence has been accumulated in the past decade showing that bone also functions as an endocrine organ that regulates systemic glucose and energy metabolism." https://sci-hub.se/https://www.sciencedirect.com/science/article/abs/pii/S0006295217300631

BSD vs. Linux flamewar trigger
Well, I just posted this paper to the 
and I fully expect a flamewar of gargantuan proportions to develop.
I am posting it here because it is actually a study on reliability, one of the very few which are around, and it is worth taking notice of:
J. Ruohonen and K. Rindell, "Empirical Notes on the Interaction Between Continuous Kernel Fuzzing and Development”
https://arxiv.org/abs/1909.02441
"Pharmacological uses and perspectives of heavy water and deuterated compounds" https://www.nrcresearchpress.com/doi/10.1139/y99-005
in english, Heterocephalus glaber is called a "naked mole-rat", but in my first language, it's called a "[naked hole digger]" so each time you listen to some kind of cancer research being presented you end up thinking about burly men with shovels and way too much visible skin

After a few hours of bring up, finding out that the 1v2 and 3v3 regulators were swapped and matching LED resistors. The Glasgow revC1 passes it's self test! This is very exciting! Now I can send the prototypes to the core developers for validation! :D

Setting up a jig to apply solder paste to the top side of the Glasgow was easier than I expected! Glasgow has generous margins around the edges making it fairly easy.

The engineering of the giant dragonflies of the Permian: revised body mass, power, air supply, thermoregulation and the role of air density

It looks like Meganeura monyi, with a mass of 150 g, would have flapped its wings at 3 Hz, which means it'd look more like a bird than an insect. It would also have a whole lot of thermoregulation issues even without flight; just rejecting solar heat.

Now that both sides of Glasgow are programmed I can run the PnP table top optimizer. It places all the necessary feeders so that the parts with the highest placement count are closest to the board. This saves on the nozzle travel time. Glasgow has a lot of unique parts!

The PnP machine programming for the Glasgow digital interface explorer revC1 front and back side are done. Setting up the new IC profiles for the parts that I don't have in my database always takes the longest time as I have to double and triple check the datasheets.

The Glasgow digital interface explorer revC1 prototype boards arrived! I will change Hana drawing to be only outlines so she also looks good on a white background PCB in the next update. Yes they did arrive a little while back but I did not have the spare time to work on them.

Just placed an order for some Glasgow digital interface explorer revC1 prototype boards! Can't wait to assemble them! :)
*taps mic* does this thing still work or has everyone left while i was trying to get a brain to cooperate

sometimes i wonder if i should post anything here other than biomed snippets, and each time this place feels inexplicably hostile.
i don't know why; it's odd
