conorh··on The Astonishingly High Administrative Costs of U.S. Health Care
At my wife's practice they employ two people full time just to do insurance authorizations.

edit: actually one of those people does verification (checking to see what insurance patients have, what is covered, and estimate what they will owe) and the other person just does authorization (getting the insurance company to approve the procedure)

conorh··on Surgeon Atul Gawande selected as CEO of new health care company from Amazon
He seems like a very smart guy and an excellent communicator - I wonder if he'll be able to step up and make this role work. I will be rooting for him because the industry needs some players with deep pockets to step in and innovate.

On a side note I find it funny in a sort of inside baseball way that his description of an operation that he does, that he describes in detail and holds up as an example, drives my surgeon wife up the wall because it is not great (she does a lot more of them).

conorh··on Prevalence of vitamin D deficiency in adults admitted to psychiatric hospital
Yes, several times a week. She is a parathyroid surgeon.
conorh··on Prevalence of vitamin D deficiency in adults admitted to psychiatric hospital
If you are going to supplement your vitamin D, just make sure to monitor your calcium too. My wife sees patients taking high doses of vitamin D, because their doctor puts them on it, or they do it themselves, and they do not realize that they are doing massive damage to their bodies because their low vitamin D levels are caused by a parathyroid tumor.

conorh··on Don’t buy the MacBook Pros even on sale, in my opinion
This happened to my wife's macbook pro spacebar, $600 fix. It happens with mine every so often too, but fingers crossed it has 'fixed' itself each time.
conorh··on How to Learn Piano with Technology
I'm 40 years old, starting working with the Simply Piano app a few months ago and spend about 30 minutes to an hour each day practicing. I have zero prior musical experience. I think a piano teacher would probably be an excellent investment, my daughter started piano around the same time with a teacher and she is progressing slower, but I can see that she already has a much more solid base than I do and will learn to play much better than I likely ever will. However I'm not in this to learn in any serious way, just to noodle around and play songs that I like and I find that working with an app that gives instant feedback is a relaxed and low pressure way to do that.

conorh··on AWS DeepLens – Deep learning enabled video camera for developers
Sure will do, mostly I've been training squirrel recognition models on my laptop and also learning what it takes to run those models on the raspberry pi (low frame rates) with OpenCV. I did also buy one of these though https://www.adafruit.com/product/997 so once I get everything running I may also have videos of squirrels being sprayed by the garden hose :)
conorh··on AWS DeepLens – Deep learning enabled video camera for developers
This is great for my chicken coop project :) I have been working with a raspberry pi and camera to train a system to recognize and respond to squirrels (close the feeder to stop them eating food). There are many other options to build this, but it is nice that this is an integrated system that is easy to train!

conorh··on Patients with Access to Legal Medical Cannabis Are More Likely to Quit Opioids
My mother in law fits this group - long time opioid user due to chronic pain from lupus and various complications. Recently went on medical marijuana and dropped her opioid usage way down. There were other ancillary benefits too, less anxiety being a major one.
conorh··on Local Rails Development with Docker and Docker Compose
We've attempted this setup a few times with Rails, but we ran into the issue that the Docker OSXFS performance for mounted volumes was too slow when working with the parts of Rails that touch many files (asset compilation for example). It made it pretty much unusable for us. I know there are some new tuning parameters https://docs.docker.com/docker-for-mac/osxfs-caching/ - we haven't tried these yet though, has anyone tried them and do they work well enough for Rails?
conorh··on Toward Go 2
Would you mind providing examples of what you are talking about? My experience has been different - I find that the golang maintainers are thoughtful but also very very (very) busy people. So I find they tend to respond in a terse, and sometimes what might seem like an unfriendly way, but I haven't seen any of what you mention here.
conorh··on Defense Contractor Left Sensitive Pentagon Files on Unprotected AWS S3 Bucket
We had this issue previously as one of our clients was using cyberduck to upload files and it had default read access for public for uploads.

conorh··on Rails 5.1 Released: Loving JavaScript, System Tests, Encrypted Secrets, and More
I love the way Rails does new releases, always some good features in there. Been working with 5.1 since the initial rcs and using the Capybara, encrypted secrets and webpack integration - all have been working well.
conorh··on How to Raise a Creative Child – Step One: Back Off (2016)
> "These measures don't correlate well with the physician's credentials."

This. I think I've even posted about this here before. This has been my wife's experience too (surgeon). She trained with highly regarded academic surgeons that set the treatment recommendations and standards for her field. Then during her job search she went to a center with, well, surgeons not at all academic and she had a life changing moment because she realized their operations and outcomes (utilization, efficiency etc.) are far far better. At the academic centers you are recognized based on your research and publications, not on your surgical skills. These academic surgeons with relatively little experience are setting the standards for how the operation should be done and what the treatments should be. This is not at all recognized in her field unfortunately and is quite literally harming patients every day because of substandard treatment standards.

conorh··on Summary of the Amazon S3 Service Disruption
This part is also interesting:

> While this is an operation that we have relied on to maintain our systems since the launch of S3, we have not completely restarted the index subsystem or the placement subsystem in our larger regions for many years.

These sorts of things make me understand why the Netflix "Chaos Gorilla" style of operating is so important. As they say in this post:

> We build our systems with the assumption that things will occasionally fail

Failure at every level has to be simulated pretty often to understand how to handle it, and it is a really difficult problem to solve well.

conorh··on What should a young person do with $20,000?
Take half and invest it in an index fund. Take the rest and travel for a year.
conorh··on VR
I'm a casual gamer, enjoy gaming and like to buy a game and play it with my kids as a family activity. I bought an oculus rift when it came out, figuring it would be fun to try out. Everyone used it a few times and then it just sat there. Most of the enjoyment we get out of gaming is sitting around and interacting while playing, that really didn't work very well with the bulky headset on one person. I think maybe in a few years when the headsets are cheaper, smaller, and easier to manage then it will make sense, but I'm not sure that will be for a while.
conorh··on Google Data Studio
I have several websites with a reasonable number of users running on both MySQL and Postgres. On the balance I think I prefer MySQL - I find the replication in MySQL quite a lot simpler and the issues are not that big of a deal, and well known. Although I will say that both databases are fixing their faults as time goes on. For example Postgres is getting easier to configure replication and as of MySQL 5.7 the silent truncate default STRICT_TRANS_TABLES/STRICT_ALL_TABLES is fixed (although generally implementations I've used set SQL_MODE='STRICT_ALL_TABLES' by default, so it hasn't been an issue).
conorh··on Building a Shop with Sub-Second Page Loads: Lessons Learned
This is not a new trend. This is a trend since the dawn of, well, as long as I've been programming, ~20 years now. Turns out that most of the time there are many more important things than your stack or language speed, and yes, often times "fix it later" is the right tradeoff.
conorh··on Hillary Clinton’s Email Was Probably Hacked
What a terrible completely information free clickbait article.

"When the F.B.I. director, James B. Comey, said on Tuesday that his investigators had no “direct evidence” that Hillary Clinton’s email account had been “successfully hacked,” both private experts and federal investigators immediately understood his meaning: It very likely had been breached, but the intruders were far too skilled to leave evidence of their work."

Or aside from the rampant speculation in this article it could also mean just what he said!

conorh··on Why I Would Raise Chickens
Some interesting reasons there for first world chicken raising, but I'd disagree with most of them from my experience:

- lock you at home: with an automatic door on the coop (ours free range), waterer and multi day feeder, you can leave them for a week, possibly longer. If we moved we'd just give them away (or well, I'd probably eat them, but I'd be voted down)

- huge garden and social use: We don't have a big garden. They happily co-exist in the garden with our kids and friends running around with them.

- reliably lay: for their laying period chickens that are bred for laying are incredibly reliable. We have four chickens and get four eggs a day like clockwork.

- don't have the time: I spend about an hour a week taking care of the chickens. Collect the eggs once a day and clean the coop on the weekend.

- rats: They do attract rats if you keep their food easily accessible. This is definitely a problem. There are feeders that make this harder, we have one and it seems to work.

- gardening: The gardening thing could be true I guess, but my wife is an avid gardener and she seems to make it work. I think you just change your gardening practices a little. She does like their manure for compost.

- cost of keeping them vs fiscal benefit: this is an interesting one. I haven't done the numbers, but I know people who raise small flocks specifically to make money. I doubt I'm making money on them, but they seem incredibly cheap to raise to me.

conorh··on Why I Would Raise Chickens
Ours only make noise when they are laying eggs. We have 4 in our pretty small yard and ours make quite a lot of noise when they are laying, but that only lasts a few minutes usually.
conorh··on Why I Quit My Job to Travel the World
Hah. It is true that a lot of the people traveling are 'privileged', but probably not with 60k a month trust funds :) They are just privileged by where they were born, the value of their currency and the support they might have from family. A lot of the people I met when I did my traveling had little savings, had worked their asses off to save up for the trip and didn't have any employment lined up for when they get back. As software developers we are doubly lucky to have jobs that are portable worldwide and in demand, I did a little consulting on the way to help pay for things.

btw if you have an urge to do this do it before you have kids - after that, well, not going to happen probably.

conorh··on Ruby has been fast enough for 13 years
I work at a dev shop and we've been developing web apps for 10 years or so. We've run through PHP, Rails, Node, Python (Django) and lately Go. For the types of apps that we develop, web apps, or perhaps web apps with an API. We have found that ruby/rails is our fastest and happiest combination. It is the slowest combination in terms of code execution speed, but in terms of speed of development and developer happiness it Just Works (tm) and allows us to get reasonable code developed at lower cost. We deploy many sized apps from tiny one server apps to small/mid sized apps with 100k users, but we've never found the speed of Ruby to be a big issue - usually it is everything else, testing, maintainability etc. If speed is an issue we've always been able to work around it without too much difficulty, and these days if we know we will need the speed or scaling we'll resort to Go, but we find that our development time increases somewhat.
