When it’s really really cold it is usually very calm winds. This lets the cold air pool near the ground. It’s unusual to have really extreme cold and high wind. This story is a little weird bc the coldest temp ever recorded is -128.6 on the

This app: https://selfcontrolapp.com/ I don't quite know how it works, but it allows me to setup a website block list that I can't get around. I'm sure if I really tried I could figure out what it changed and

I do! I like my coffee straight up and if I want coffee, will stand in line for 10 minutes for it.

I have a memory from when I was a kid and learning about the universe. In my head it definitely had an edge, and it resembled a really really big hockey rink with boards. But it was also only 2d at that time, which I think I remember knowin

I've done a lot of ultralight backpacking. That community is, in general, on the more liberal/hippie side of the spectrum. One of the funniest things I noticed however is that the far other end, the doomsday-preppers, start to sha

One of my favorite quotes is "Good judgement comes from experience; experience comes from bad judgement". I really like this article for showing the other side to viewing other people's mistakes... almost everyone very experi

"Harms 0% non-old and non-weak population" -- completely 100% demonstrably false. One of my friends older sisters, in her late 20's came down with the flu at night, then in the morning didn't go to school (she was a teac

One of my coaches in college raced for a pro/semi-pro team. Their first race of the season was on new/pre-production bikes straight from one of the major manufacturers. 3, I repeat, 3 steer tubes broke in that 1 race. It was a rea

After having worked with Google's Health API & HAPI FHRI, I really appreciate the "other" features that are baked into this like auth and user management. We ended up proxying all of our FHIR requests through Rails to HAP

Your use of custom StructureDefinitions for the very non-FHIR models that you need is impressive. I don't think I've seen such a clear example out there of someone extending FHIR to this degree. Well done!

by xcskier56 4y ago
Thanks for the thoughts! I agree that FHIR extensions are clunky and very commonly the data you're trying to store can be represented by a FHIR resource. Extensions are clunky, but for some of our projects have been the only way to sto

Another question that I can't quite figure out from your docs is if your bots functionality works with non-AWS hosting?

Very cool and impressive work! One question I have is how you think about handling custom data fields. FHIR has the `extension` attribute on all DomainResources that allows you to store any non-standard information, but building code and va

The view from below of the boosters after entry burn where you can clearly see they're not just falling straight down but actually achieving some horizontal velocity across the ground was really cool. I've always known that they h

by xcskier56 4y ago
The booster was doing 14,000km/h at MECO which is about 3.8km/s. Orbital velocity is 7-7.5km/s depending on altitude and escape velocity is even higher, so no, it was not at escape velocity or anywhere near it.

I’m not sure if they developed them themselves, but the alloys SpaceX uses in the pre burners in the raptor engines are really advanced and likely have not been known (in the US) before. They have to be able to withstand pure (nearly) oxyge

The hierarchical nature of the information he's talking about really reminds me of the ontologies and terminologies that are used in healthcare to organize medical information. E.g. Ibuprofen 10mg Tab < Ibuprofen < NSAID < ...

I have always had a very strong internal sense of direction and I've found that it relies strongly on knowing which way is north. This means that when I'm in a mall or other large building (malls are the worst) I get very lost and

I use AWS all the time and for startups I 100% agree with this. Sure, I could get a cool stack up and running in AWS much faster than this article, but the infrastructure by its self delivers ZERO value even if it’s shiny and fun to work on

One of the big caveats is that the information must be personally identifiable AND include information about the care of that person. Just my going to the website of a healthcare organization doesn't immediately identify me as a patien

Another trade off: Liquid hydrogen is very low density, and requires extremely low temperatures. This means that you need a much bigger tank for a given weight of fuel, and that tank needs to be insulated bc liquid hydrogen must be kept bel

While I see the great potential in this technology, the collateral damage is the loss of places where one can truly disconnect. I just got back from 4 days camping at a remote mountain lake with zero phone coverage, and it’s one of the most

I’m know there are other more complex applications of a message queue, but I really appreciate the fact that Rails has simplified this very common functionality so much that it’s not a “message queue” but simply background job processing. F

There are a few coincidences in the imperial system that make life easy. That highway driving speed is around 1 mile per minute is a pure coincidence. Most/all of the other examples you list are pretty useless to me for daily life: - A
