brown··on Launch HN: Medplum (YC S22) – Open-Source Firebase for Healthcare
Thanks! It means a lot from someone in the space. There is a ton of duplicated effort out there.

Good question. We take this seriously, and try to keep the dependency footprint small (which is a challenge in the node/npm ecosystem). We try to stick with large, battle-tested dependencies (express, react, etc). For less popular projects, we will clone and run and perform our own internal audit.

We also follow best practices with automated tools like Sonar and Dependabot to automatically scan dependencies. We've gone through multiple pen tests. There's no silver bullet though, so it's a constant battle.

Thanks!

Good question. Custom data is tricky. The first thing we always try to do is dig deep into the FHIR spec to see if the data is truly custom, or if there is an existing FHIR representation that will actually work. In many cases, there are good options, and it's nice to work within the spec.

If not, then falling back to extensions is the next logical step. FHIR extensions can be clunky to work with. Our client libraries provide a bunch of helper utilities to make it easier.

In extreme cases, we have created custom FHIR resources via custom StructureDefinition and SearchParameter resources to represent completely unique data elements (examples: https://github.com/medplum/medplum/blob/main/packages/defini...).

That's a great question. Healthcare tech is a big and diverse space, and we are still honing a product description that speaks to all audiences.

Among technical decision makers (Software Engineers, Architects, etc), the Firebase analogy clicks much faster. Among traditional healthcare administrators, "EHR" or "API first EHR" or "Headless EHR" resonate more.

We're definitely open to suggestions!

brown··on Rust 2024 the Year of Everywhere?
I could not disagree more.

The moment you need to do something remarkably simple, such as string concatenation, you are confronted with the reality that Rust is a much lower level language.

brown··on Launch HN: Payload (YC S22) – Headless CMS for Developers
Congrats! So much opportunity for an API-first CMS.
brown··on The Only Unbreakable Law [video]
Nice video. Conway's 1968 paper is a good find.

The conclusion is slightly defeatist, but ultimately correct. At time 49:23, Casey says "But we have to do them right now, because we haven't figured out how to do it better."

[excessive modularity] is the worst form of [software development] – except for all the others that have been tried.

brown··on Disasters I've seen in a microservices world
Next up, leftpad.io, leftpad as a service.
brown··on Do I have to worry about copyright issues for code posted on Stack Overflow?
Previous company went through source code audit during acquisition. Auditor inevitably found code from Stack Overflow. Their guidance, which got us a passing grade, was to just include links to the SO answer and link to CC in a nearby comment in the code.

This is not legal advice, just sharing our story.

brown··on IAM is hard – Thoughts on $80M fine from the Capital One Breach
IAM wildcards are the new chmod 777.
brown··on Why are we so quick to scrutinise how low-income families spend their money?
Yes?
brown··on From Java to Go, and Back Again (2016)
Language wars aside, I liked this:

Returning to Java (and Kotlin) development after a couple of months of Go development, [...] I discovered the value of a certain sort of "plain speaking" in code.

This resonates with me. I've spent 1 year+ in each of C, C++, C#, PHP, Java, Python, and JS. There are obvious benefits to taking advantage of a platform's strengths, but the "plain" code has merits too. Easier to reason about, often more maintainable, faster to ramp up new team members, etc.

brown··on Is the Age-Old Quest for a Baldness Cure Reaching Its End?
Gene Roddenberry was asked by a reporter about casting Patrick Stewart in Star Trek: TNG. "Surely by the 24th century, they would have found a cure for male pattern baldness." And Gene Roddenberry responded "No, by the 24th century, no one will care."

Should You Give Money to Homeless People?

http://www.theatlantic.com/business/archive/2011/03/should-y...

"The short answer is no. The long answer is yes, but only if you work for an organization that can ensure the money is spent wisely."

Reversal of Fortune is a 2005 Showtime documentary that asks the question "What would a homeless person do if they were given $100,000?"

https://en.wikipedia.org/wiki/Reversal_of_Fortune_(2005_film...

"When asked by Oprah how much of the $100,000 he still had, Ted replied "none." Ted also mentioned that he is homeless again, and content with his current circumstances."

brown··on San Francisco's homeless problem: A civic disgrace
The unique part of SF is our extreme inefficiency. We spend huge sums of money without much to show for it.

Homelessness is a crisis that is growing all over the US.

brown··on San Francisco's homeless problem: A civic disgrace
Not all of them. As the article states, SF "gets an influx of about 450 chronically homeless people a year".

Part of the problem is that SF has become known as a sanctuary city for the homeless. People come from all over the US. That is good, from the perspective that we have some positive karma for treating people better than other cities. It is bad, from the perspective that we bear more of the burden.

brown··on San Francisco's homeless problem: A civic disgrace
Indeed, but as the article points out, we can do a much better job of managing the problem. Paying $150,000 per year per person is simply ridiculous. We can look at Salt Lake City and Houston for proven examples of better solutions.
brown··on The Best Linux Distros of 2016
How do you tell if someone uses Arch Linux?

They tell you.

brown··on We only hire the trendiest
Not the OP, but I would have used the word "caginess" or "excess self preservation".

You don't want to hire a shark who's going to work against you.

Congrats to Christian and the Etleap team! Smart team, good product.

brown··on How St. Louis County, Missouri Profits from Poverty
If you're a millionaire, a $50 speeding ticket is barely a deterrent. If you're poor, the same $50 speeding ticket can completely break you. That doesn't feel right.

As much as I personally would dislike it, Finland's model for traffic fines is probably a more "fair" strategy.

brown··on MedXT (YC W13) Announces FDA-Cleared Medical Image Platform
The silver lining of regulatory burden is that there is less competition and higher willingness to pay. It is still annoying though.

Jonathan Bush, CEO of athenahealth, recently ranted at congress about excessive healthcare regulation. His frustration was palpable: https://www.youtube.com/watch?v=CekfvGDiab8

brown··on Show HN: I built a live Bitcoin price aggregator with multiple indexes
That's a classic arbitrage strategy. It works. The only reason that traditional "big" finance isn't doing it yet is that Bitcoin is too small/new.

As for risks:
