SteveCoast··on Things I Wish I’d Known Before My Chronic Illness
The recent uproar about the NEJM issue containing only marketing is the counterpoint. Dr Fung pointed out that there's no wonder people turn to GOOP when the system is so broken.

So while I understand and appreciate your point, I don't think you understand how corrupted medicine has become. It's now a necessity to do your own research.

Dr Wahls curing of her own MS would be another example.

FWIW there are a fair number of people who report good results for this and the original post issues with keto, fasting and related things on Reddit. A bunch of claims around gluten too.

SteveCoast··on Lufthansa Is Suing a Passenger for Missing a Flight
Competition on high volume routes plus larger aircraft on those routes to amortize the costs.

This is exactly what happened with trains. High volume routes saw a lot of competition and were very cheap and local routes were very expensive. So I can often fly Denver to London cheaper than Denver to Durango, CO.

There's more parallels around regulating trains and how the train companies were eventually bankrupted and taken over, with the inverse happening around when Southwest was new.

SteveCoast··on Gum disease–causing bacteria could spur Alzheimer’s
Exactly, and put better than I could.

It appears that the simplicity of the explanation is itself a problem. Surely - all these chronic diseases can't be that simply explained? Dr. Wahls essentially claims carbs are the root cause of MS, which she cured in herself (with the corollary that carbs eliminate other nutrition). Dr. Fung claims it's the root cause of diabetes. Prof Seyfried claims it's the root cause of cancer. It surely can't be that simple?

Reading all their work, and others, I'm struck that it's very much a five-whys scenario[1].

Also there are two points wrapped up in the original response. One is about the cause, but there's a bigger issue about the avoidance of the problem in a first place. If someone never eats refined carbs and therefor avoids the root cause, why would they care about the details of the cause? We care about the details insomuch as we would like to treat the disease, but today we can't do that. On the other hand we do know with a lot of certainty that eating well, fasting and exercising are good for us and avoid the problems in the first place. For some reason, that doesn't matter as much.

The downside with treating the disease is that you also enable it, like how we "treat" T2 diabetes by essentially just giving you more diabetes via insulin shots.

The much simpler explanation is they're both caused by carbohydrates and especially sugar.
SteveCoast··on New Dell XPS 13 developer edition now available
I have an XPS 2-in-1 and I open to 180 degrees sometimes when laying down and using the touchscreen. It sometimes works in economy seats as you can rest the laptop on your lap and then the screen is kind of like a seatback IFE. But if you opened it flat on your lap, the screen can't open that far because of the restrictions of the seat in front of you. I also will put it in "tent mode" e.g. over 270 degrees open and the screen upside down on the tray table to watch a movie.

About the only thing I don't do much is use it as a tablet as its kind of heavy, even though I have the Dell pen for it.

SteveCoast··on Ford Buying San Francisco-Area E-Scooter Startup Spin
Humans will always need to move around, yet it's not clear how we'll move around in the future. While self-driving cars have potential it's not clear that dense urban areas will make a ton of sense for them, and so perhaps bikes or scooters or something else will become the norm.

On the other hand, we spend enormous amounts of money on other solutions like busses or underground metro systems in dense urban areas which have significant problems like not taking you where you want to go. If there are systems which do get you where you want to go you might not have to make those up front and gigantic investments in future.

If you have systems which are point to point, then the value of real estate that isn't near a metro stop can go up since you don't have to price in the walk from that place to a metro stop. There are all kinds of fun implications.

Also, scooters might only be step 1. Maybe self-driving scooters with a 5 mile range are step 2, or something.

So if you compare to existing systems you can argue that scooter valuations are cheap if that's the direction we're going, though that isn't certain.

SteveCoast··on FAA Issues Boeing 737 AOA Directive After Lion Air Crash
From memory; pitot tubes froze over and airspeed became unreliable. Autopilot disengaged and they had a stall warning. One pilot went full nose down, the other wanted full nose up. The latter probably believed the flight envelope protections were still in place which would not let you stall even if you did full nose up. But they weren't because the flight computer switched to alternate law when airspeed was unreliable so they had full control of the airplane and (probably) didn't realize it. Additionally when presented with two different control stick inputs the flight computer just averaged them, and since there was no force feedback there is no tactile sense that you're arguing with the other pilot over what you should be doing. Also only one person is supposed to be in command.

My memory is also that the senior captain was in the third seat and didn't have a full grasp of the situation either.

I did read the air accident report quite a while ago so this might be wrong, but in summary, it's not exactly arguable that the aircraft did the wrong thing (it did as designed minus the freeze issue which is suboptimal but something that can happen) and the pilots didn't exactly do the wrong thing either since they may have little to no experience flying the plane in alternate law (certainly not at high altitude and speed), and it's not unreasonable to be fully aware that they had full control (as opposed to the flight computer mediating and not letting them do something stupid like stall it all the way down to the ocean).

Lastly, when in cruise it's not completely trivial to fly like a Cessna at 1,000ft. At cruise on a big heavy jet you can't go much higher as the air is too thin to fly. You can't go much faster without braking the sound barrier. You can't go much slower as you'll stall. I believe it's called "coffin corner", and while commercial passenger planes do it every day it's not quite as simple as you might think.

SteveCoast··on Amazon is stuffing its search results pages with ads
Trying to find real data that amazon prices are going up:

Is it this product?

https://camelcamelcamel.com/Dr-Elseys-Premium-Clumping-Litte...

It looks like the price has been roughly the same for 4 years with jumps up and down. And before that, declined a lot.

If we include inflation the price seems to be declining.

Here's a graph for a chair mat:

https://camelcamelcamel.com/AmazonBasics-Carpet-Chair-Mat-47...

If anything, the graphs seem to show a lack of price discovery as it's not jumping around enough. Maybe camelcamelcamel doesn't sample at a high enough frequency.

I agree if the prices are now really higher. They don't "feel" higher to me. Here's cat litter that's $17.49 (one of the root comments mentioned this but it might not be the identical product):

So you saved $4.40 to go to Walmart.

* There's a non-zero chunk of the population not near a Walmart or similar.

* It costs time to go there

* It costs vehicle depreciation

So if you were going to Walmart anyway, or walked there with nothing better to do you saved the money.

But if you didn't then let's say the average wage is $25/hour or so and you spent 30 minutes there and back, and fully loaded vehicle depreciation is 50 cents/mile and it's 5 miles away then you spent $17.50 to go there.

I totally realize we could argue all this back and forth but just pointing out that most of the time the "savings" aren't real if you value your time and transport. And yes, I realize most people don't value their time and treat their transport as a sunk cost even if it isn't entirely.

edit: I was assuming going to walmart in person as opposed to online, because that's what most people appear to do but I'm happy to be wrong :-)

SteveCoast··on The 20-Hour Flight Is Coming, and It May Have a Gym and Bunks
Lay flat seems pretty common internationally, United Polaris for example...
SteveCoast··on The 20-Hour Flight Is Coming, and It May Have a Gym and Bunks
I spent some time on this a while ago and it's not quite as simple as I'd hoped.

People typically need to be facing/laying along the axis of flight for the seatbelt to work. If you're laying at 90 degrees and there's a big (de/a)cceleration and you have a belt across your waist, you get folded in half hanging off the bed.

If you stack three people on top of each other then the you need egress (space one one or both sides of the beds) which takes up a bunch of space to get back/forward. Most seats have the aisle as egress but you need more mini-aisles for bunkbeds. You might want to divide it and say some people have egress forward and some backward to save the space... but if there's some kind of emergency you want people to be able to go whatever way they want.

If you think about roughly the volume of 3x3 seats (9 pax) then roughly speaking you could have three sets of three bunkbeds. But the curvature of the airframe means you don't have the same height near the window you do in the middle of the plane, and you may take away cabin baggage space. One way to get around this is to make the lowest bunk very low, like an inch off the deck, but that would mean a smaller market as you have to have pax who can get down low or climb up to the top.

All of this is assuming you're trying to go for the same kind of density of pax as a plane has today. If you just want two bunks and charge more, or you want to have a seat and a bunk (so you sleep only half the flight or something then someone else gets the bunk...) then the space requirements all change. You can also just have some bunks or just in the middle rows on a widebody and on the outside have seats.

Lastly, my memory is the flight computers will try to direct smaller aircraft movements in the vertical axis / pitch angle. Again from memory, but people get really sick if they have a bunch of movement side to side or at some other funny angle their vestibular system isn't used to. And with bunkbeds you might not have a window to look out of for a frame of reference to help. This is another constraint on how you lay people out on the plane.

It's all fixable kind-of but not just "put in a bunch of bunkbeds and make the same amount of money / same price per seat-mile". Someone with more knowledge can probably list all the reasons the FAA wouldn't allow it.

I still want bunkbeds though.

SteveCoast··on Association of Type 2 Diabetes with Titanium Dioxide Crystals in the Pancreas
Dr Fung has been doing this for a long time, and it's not dangerous at all. My longest fast was for 14 days just water, though I wasn't diabetic.

Fung has lots of articles on Medium and /r/fasting is a great resource. Fung and also Taubes books are great and point out he maddening simplicity, that diabetes is high insulin is high sugar intake and that we treat it with... higher insulin. It's insanity, and because we can't see the wood for the trees we have smart people go study things like how much titanium you have in your body rather than solving the actual problem of carb intake.

I just read a book about Henry Ford. They evolved the model T rapidly so models coming off the line weeks or months apart had significant differences. They kept evolving it for years

SteveCoast··on Geolocating requests with Google Load Balancer for free
Ha.

Well right now a) we most likely have no idea where an ip address is and b) even if we do, it's nearest-city accuracy.... which is exactly what everyone else does.

Denying browser location doesn't stop the app or website from using your ip address against some third party service to figure out where you are.

SteveCoast··on Geolocating requests with Google Load Balancer for free
I've been working on and off on a system to build this data for free - https://www.open-geo-ip.com/

It uses your browser location to build the data, bootstrapped with Mechanical Turk workers around the world. It has one feedback loop, where if you use the JS library it will give you the users location if they deny browser location (if we have the data...) and if they do share location, then we update the database (but throw away the last part of their IP address).

There are two or three other loops where we could build more data (which you can get here https://www.open-geo-ip.com/data/download ).

I'm probably going to do a small kickstarter to pay for some cleanup and expansion work or just kill it if that fails to get funded. Any ideas appreciated on things to do with it.
