crygin··on Gravitational pull 'has role in quakes'
There's some research out there that correlates certain types of marine quakes with tidal levels: http://onlinelibrary.wiley.com/doi/10.1111/j.1365-246X.2009....
crygin··on A Brief History of Bog Butter
Good post on Bog Butter from Nordic Food Lab: http://nordicfoodlab.org/blog/2013/10/bog-butter-a-gastronom...
crygin··on Theranos’s Fate Rests with a Founder Who Answers Only to Herself
Heh, this is, bluntly... untrue. In medicine, certain types of published studies are sometimes peer-reviewed, and sometimes people care about that, and that's about the extent of peer review as far as validity goes. Drug studies are not peer-reviewed in any meaningful way, and that's about as statistically strong a claim as exists in most of medicine. Medtech (implants, mechanisms, Theranos-like processes, etc) are certainly never "peer-reviewed".
crygin··on Wine Tech Upstart Drops Smart Bottle on a $300B Industry
This is bizarre. Insofar as this is solving a "problem", it's essentially solved by a Coravin, and I never thought I'd say this about the Coravin, but cheaper given that anyone who wants to do this will want to do with multiple wines (aside from overenthusiastic hobbyists, Coravins are mostly used to serve very expensive wines by the glass).

EDIT: I think I misread initially -- you can use it for multiple bottles, but only their prepackaged wines? No one with this money to burn on wine accessories is going to want the narrow range of wines they're going to be able to offer.

crygin··on What we’re doing to the Earth has no parallel in 66M yrs, scientists say
Sorry for the next-day response, went to bed shortly after posting that.

Long story short, this paper received a lot of press attention when it was published to the ACPD last summer for discussion: http://dotearth.blogs.nytimes.com/2015/07/23/whiplash-warnin...

Which led to a fair number of climate scientists upset about what they saw as the press reporting on preliminary results. It's linked in that article but the key point is that Hansen has spent the last ~10 years calling out what he sees as a reticent attitude among climate scientists towards (what he feels is justified) alarmism: http://iopscience.iop.org/1748-9326/2/2/024002/fulltext/

crygin··on What we’re doing to the Earth has no parallel in 66M yrs, scientists say
James Hansen is somewhat controversial, but this paper has been reviewed and accepted for publication in Atmospheric Chemistry and Physics, and it's very serious: https://app.box.com/s/i4u002tbpcvkamj9wq4n8t1u8wxsjhis

I'd summarize but anyone interested in the near-term (this century) effects of climate change and already on HN should be willing to read the actual paper.

crygin··on Ignore the GPS – That Ocean Is Not a Road
One of my favorite examples of this is using Google Maps to find your way from Monument Valley to Natural Bridges or vice versa -- sends you right up/down the Moki Dugway, which despite being part of a state highway is not a road for everyone.
crygin··on Grisly find suggests humans inhabited Arctic 45,000 years ago
Archaeological evidence indicates that the Inuit were generally involved in trade and border disputes with First Nations groups living south of the Arctic tree line. The "modern" Inuit that made contact with Europeans were a much smaller, more homogenous group than existed mere hundreds of years earlier, after being collectively forced to move south during the Little Ice Age.
crygin··on November 2015 was warmest November on record
This is more likely El Nino-related (the extremely strong El Nino currently in process is likely to make the East & South much warmer than usual), though of course worldwide temperature increases will compound to make the temperature higher than it might have been without climate change. My understanding is that it's still fairly unclear how climate change might be affecting equatorial oscillations like El Nino (as opposed to the Arctic/North Atlantic oscillations where there are some pretty specific mechanisms of action hypothesized).
crygin··on Deepwater Horizon Dispersants Backfired
Fair point, it's somewhat hyperbolic phrasing. A perhaps somewhat retroactive defence:

Surface contamination is deadly, particularly to bird/shore life, but dispersed oil is deadly throughout the water column (until it resurfaces, at which point it becomes deadly to birds again). There's relatively little life at the surface compared to the pelagic zone, so the impact of dispersants doesn't merely multiply the effect of the oil by the depth of the water, but actually moves that oil into the regions where life is densest.

crygin··on Deepwater Horizon Dispersants Backfired
Preauthorization for use of dispersants had already been withdrawn for Prince William Sound (the only zone in Alaska where they had been preauthorized) by the Department of the Interior in 2008 following this consensus report: http://dels.nas.edu/Report/Spill-Dispersants-Efficacy-Effect...

This is also an interesting and well-known report discussing the non-mechanical response to the Valdez spill from 2006: http://www.pwsrcac.org/wp-content/uploads/filebase/programs/...

I can't be clear enough on this -- the impact of dispersants on the environment and their lack of efficacy at actually decomposing oil (see: resurfacing) was well-known at the time of the Deepwater Horizon spill. There's ample discussion from the actual professionals in this field at the time of the incident regarding the obviously inadequate cleanup process. The responses from both BP and the EPA were meant to reduce metrics like visible sheen while ignoring the environment (it's even worse in the gulf since current variation at depth results in a much broader resurfacing pattern than simply leaving the oil on the surface would have done).

crygin··on Deepwater Horizon Dispersants Backfired
This is, unfortunately, quite well-known in the oil spill management community. We've chosen to measure incident response using visible oil on the surface of the water, so the companies use a method which reduces that metric but causes exponentially more environmental damage throughout the water column.
crygin··on Leading mathematician launches arXiv 'overlay' journal
Blind (or double-blind) review in most of academia is inherently impossible -- the people qualified to do the review will generally be able to recognize who the paper must have come from.

I agree that blinding would be preferable, but when the material itself reveals the author it's simply not possible.

crygin··on San Francisco Should Always Have a Subway Under Construction
That's 3.5 times the cost per foot than in Denver.

Heh, given that land out there east of the Arsenal refuge is almost free and the cost of building an elevated structure in an earthquake zone... this comparison is the first time the AirBART replacement has sounded cheap!

crygin··on What's Really Warming the World?
Ugh. This is exactly the type of poorly-informed response you generally get when people attempt to "read the data" for themselves with little to no understanding of the science behind it. Seems to be a lot of that going around HN today.
crygin··on Cinder (YC W15) – Smart Countertop Grill
It's a combination of temp & time -- 131F for four hours will pasteurize (and, conveniently, is below the coagulation temperature for both the white & yolk of eggs, so you can home-pasteurize eggs for mayo/etc with a water bath). Contrariwise, 140F wouldn't be safe if it only reached it for a few seconds.
crygin··on Cinder (YC W15) – Smart Countertop Grill
This definitely seems complementary to rather than a replacement for sous vide cooking (especially in terms of e.g. gelatinizing collagen in rare meat, since you'd get oxidative off-flavors over the duration necessary using your device).

I'd be very interested in hearing more comparisons between your device's caramelization abilities and e.g. pressure-cooker caramelization with or without added alkaline agents. My experiments doing temp-controlled caramelization in ambient air (rather than the hydrating environment of a pressure cooker) have had mixed results.

Will you have any physical demos in the bay area?

crygin··on U.S. Droughts Predicted to Be the Worst in 1,000 Years
The current consensus is that the drought will extend to the Great Plains. See for example this paper (recently discussed at the AAAS meeting): http://advances.sciencemag.org/content/1/1/e1400082

This is not a possible shift to an environment with a recent (human-timescale) analogue. If it comes to pass, we will not be able to farm or live in the same places or at the same volumes as we are currently capable of.

crygin··on The Etherkiller (2002)
I still have a 3.5" floppy disk that a friend of mine made in middle school in which he replaced the magnetic medium with a sheet of black fine-grit sandpaper. I don't think anyone ever used it, fortunately.
crygin··on Passenger Pigeon Comeback
That's commonly cited as fact, but the truth is we don't know that they required large flocks to survive (deforestation is another possibility). Charles Mann points out in his book 1491 that e.g. DeSoto didn't report large groups, and hypothesizes that the enormous flocks of the 1800s are an aberration due to wide-scale crop production.
crygin··on Epic Drought in West Is Literally Moving Mountains
It's also known that certain types of marine quakes are more frequent at low tide, though the weight differential involved there is orders of magnitude larger than in the case of the CA drought: http://onlinelibrary.wiley.com/doi/10.1111/j.1365-246X.2009....
crygin··on Atlantropa
Your "meanwhile" is on the order of hundreds of thousands of years, at a bare minimum, whereas the extinction of specialists can easily happen over the course of a single human lifespan.

It's not thinking critically about the issues in play or how they would affect the lives of millions or billions of people, let alone the animals, plants, and microorganisms involved. It's not heresy, it's just hubris.

crygin··on Mapping the Spread of Drought Across the U.S
I apologize for not having time right now to track down primary sources for you, but if you're interested in learning more about the current research specifically on this drought and climate, look up stuff related to the position and strength of the North Pacific High, how it's affected by the Arctic Oscillation (and decoupling of the AO from the North Atlantic Oscillation), and how those are related to extreme jet stream configurations (regarding which there is emerging evidence for a relationship with Arctic sea ice extent).

And if you find good stuff, post the links!

crygin··on Uber Makes Economists Sad
Yes. I had a friend once who took a cab to work when her bus didn't arrive, even though it meant she would have a net negative income for that day, so she wouldn't lose her job.
crygin··on Sell your S.F. street parking spot for $20?
Fair, I'd love to see some hard data on this. I don't think I've ever spent more than ten minutes looking for a spot, though it's certainly seemed like a lot longer during the process itself.
crygin··on Sell your S.F. street parking spot for $20?
$20 is probably more than enough to incentivize a market of people who will occupy spots in order to resell them, though, if this takes off. I bet you could do 10+ spots/hour driving around at the right day/time.
crygin··on Microsoft rescues XP users with emergency browser fix
Seriously. A few years ago (2010ish) I was roped into helping out with a microprobe array that would have cost about $150k to replace, whose controller software would only run on Windows 95... not OSR2, meaning that USB wouldn't even work (we used ZIP disks to move sequence files on and off of it). The fellow in charge of the thing would grab systems being surplussed from elsewhere in the department that might run Win95 and clone to their drives... when I left he had 4-5 spares in a closet for the day the current controller died.

EDIT: And we did attempt to virtualize it, but at least at the time were unable to do so successfully (timing issues, I think).

crygin··on Brendan Eich
As a single, useless data point, I'm not at all involved in the Mozilla community (though I've been a user for a very long time), or in the same-sex marriage fight, nor am I a resident of California. And my first thought when I heard the announcement was basically "really? The Prop 8 guy?"

This is pretty basic stuff for high-profile executive appointments...

crygin··on NHTSA to require backup cameras on all vehicles
Seriously. My entire rear window is unusable after five minutes on the road this winter, no idea how any rear-facing camera could function.
