I’ve had good success using lambda and functions for analytics data pipelines. It allows a team of python developers to focus on the business logic instead of the infrastructure. On my current project we’ve been struggling with K8 for months (not our decision) and I intend to push for a refactor to functions as soon as we get to MVP.

A close family member has been diagnosed with Parkinson's disease a while back. I've been trying to educate myself on neurodegenerative diseases since, with the hope of launching something one day to tackle treatments and potential cures.

I don't have a formal biology background, so there is a lot of things to learn. But I can't sit down on the sidelines without attempting to do something about it. That's what's driving this passion.

If you're in a similar boat, or have experience in building healthcare products/companies, please reach out! I've been wanting to meet likeminded individuals for quite some time.

For the common use-cases, SVGs do render consistently across browsers, but there are differences in feature support and rendering behavior outside of those.

refX/refY is one example of this. These attributes were added to the SVG spec in 2015 and didn’t have support in all major browsers until a few weeks ago.
This is amazing!

Have you looked at differential-datalog? It's rust-based, maintained by VMWare, and has a very rich, well-typed Datalog language. differential-datalog is in-memory only right now, but could be ideal to integrate your graph as a datastore or disk spill cache.

> Therefore the law applies to bicyclists as well

You left out the second part of the law you cited:

>> (1) Every person propelling a vehicle by human power has all of the rights and all of the duties applicable to the driver of any other vehicle under this chapter, *except as to special regulations in this chapter, and except as to provisions of this chapter which by their nature can have no application.*

A statute that applies to motor vehicles, by its nature, cannot apply to a pedalcyclist.

Also, the definition of the term "motor vehicle"[1] in the same chapter reads as follows:

>> (46) MOTOR VEHICLE.—Except when used in s. 316.1001, a self-propelled vehicle not operated upon rails or guideway, but not including any bicycle, electric bicycle, motorized scooter, electric personal assistive mobility device, mobile carrier, personal delivery device, swamp buggy, or moped. For purposes of s. 316.1001, “motor vehicle” has the same meaning as provided in s. 320.01(1)(a).

That definition specifically excludes bicycles.

Having maintained a service that uses Lambda. I think Lambda is probably fine for one-shot tasks, or taking from a queue (which is what it was built for), but I would never use it for API endpoints.

The main issues:
1. Unpredictable performance - latency (with cold start), concurrency limits (how quickly can we scale to X concurrent requests), etc? We spent many hours with AWS support before moving away from lambda.
2. Short running process are terrible in many ways - no DB connection pooling, no in memory cache.

I'd be much more happy if AWS fixed scale-up speed of ECS tasks so you can scale up your services in a reasonable time, than having these one-shot tasks.
The issue with those ultra-deep frequencies is that the waves become really long and the acoustics to make them behave become increasingly unwieldy the lower you go.

Dampening a the 9.8 meter long wave of a 35 Hz tone is already hard, dampening a ~19 meter long 18Hz wave mist be pretty much impossible.

The only thing more amazing than loud low bass is bone dry loud low bass that starts and stops precisely.
In AWS that post hooks workflow also is usually "firehose" apis such as events from table writes, and they work well for streaming ETL type work.

Lambdas and workflows are like SQS and workflows. you get a few of them just use lambdas and workflows, you have a lot of them switch to a workflow engine.

If the architect has taken the reins for this project, I think this will be OP’s best bet. Nearly all of the other comments on this post indicate that this plan will end badly (given what we have been told), so best be prepared to land when it all falls apart. Start the job search now.
Nothing. You should be. For any serious workload it will be wayyyy more expensive than an RI running a vm or ecs/eks running a container or two. It will also perform worse most likely or at least be less consistent.
These are great comments.
Cyberpunk 2077 at least pushed the rendering part of the engine into next-gen territory: Volumetric lightning and fog almost everywhere, environment reflection on even the smallest water surface and monochromatic light actually turns many surfaces into mirrors. All that in an outdoors setting with a ton of assets and an almost impracticle amount of verticality (no naturally empty half of the Screen).
Before that release, most game devs would have told you that this is still impossible on todays hardware.

But that engine also shows that you are not wrong with your remark about consoles holding progress back: The game barely ran on the ps4, and even on the ps5 you won't get stellar framerates... You need a really nice PC to run the thing smoothely...
Launch HN: Medplum (YC S22) – Open-Source Firebase for Healthcare
Hi HN! Cody, Reshma, and Rahul here and we’re building Medplum (https://www.medplum.com), an open-source platform that lets you quickly build complex healthcare applications. We provide a headless EHR (electronic health record) that supports common standards like FHIR, HL7 and more. You build whatever UI and UX you want, and we handle the infrastructure and give you lots of interoperability and automation tools.

The digital healthcare space has been hampered by proprietary tech, walled gardens, and vendor lock-in. Working as healthcare app developers ourselves, we kept seeing organizations developing the same infrastructure over and over. The question “how is this stuff not open source?” came up so often that we finally decided to just build it.

Out of the box, Medplum includes:

- Auth - An end-to-end identity solution for easy user authentication, sign-in, and permissions using OAuth, OpenID, and SMART App Launch

- Clinical Data Repository (CDR) - A back-end server that hosts your healthcare data in a secure, compliant, vendor neutral, and standards based repository

- A FHIR-based API for sending, receiving, and manipulating data

- SDK - Client libraries that simplify the process of interacting with our API or any FHIR server

- A web application where you can view your data, perform basic editing tasks

- UI Component Library - React components designed to help you quickly develop custom healthcare applications

- Medplum Bots - Write and run application logic server-side without needing to set up your own server

Our team has years of experience in healthcare technology. We were the founders of MedXT (YC W13) and have held engineering leadership roles at Box and One Medical.

Our repo is at https://github.com/medplum/medplum and you can see a demo video here: https://youtu.be/nf6OElRWOJ4. There’s a sample app at https://foomedical.com, with code at https://github.com/medplum/foomedical.

Medplum is under the Apache 2.0 license so any developer can use it for free with no strings attached. We make money through enterprise integrations, and by providing a hosted version and support. Compliance is a priority—we are SOC 2 and HIPAA compliant and are pursuing ONC and HITRUST. Our hosted service runs on AWS and uses cloud infrastructure similar to a typical SaaS application. This is also rare in healthcare.

We would love to know what you think - especially any recommendations or ideas you want to share, and would love to hear about your experiences developing healthcare applications!
Differential Datalog: a programming language for incremental computation
I've been building websites for about the same amount of time, and have never done JS animations and stayed away from GreenSock because I was scared of it, even though I was always curious.

This is the first time I've felt like the effort to learn and make something cool would be worth it. Thank you!
Yes, the correct word is "inaudible".

Anyone who's ever been to a live music event can attest to "detecting" sound <20Hz without their ears. And it's pretty obvious how feeling the sound in your body, especially the percussive elements, would encourage dancing.
4.26 and 4.27 still use physx by default, and their chaos version is basically unusable[1] (because of bugs and performance). There is a 4.27-chaos branch which is more updated (maybe the same version as Ue5 chaos?) but I don't know how usable it is.

But yes the future for UE is chaos.

[1] to be fair fortnite used it, but clearly they optimized and fixed only the subset of features that fortnite uses.

I think there is a lot more controversy than you’re implying, even among serious scientists, but an HN comment thread is probably not the right place to litigate a complex issue that is also a partisan political football.

I've been a cyclist in many cities. Never once seen a cop cite someone for this. I'm guessing if you got into a bad accident things would go poorly for you after it was discovered what you did, but has anyone here actually seen something come of people riding these bikes where they are banned?

The problem is that they get you in the long run when inflation erodes away the money you would have saved. There needs to be some sort of stable way of transferring that value into a medium that can retain it. I don't think anything exists that can satisfy this requirement. Everything i've seen (Bitcoin, gold, etc.) has not cut the mustard.

There's nothing inconsistent about that. Cars are multi-thousand-pound multi-hundred-horsepower machines traveling at deadly speeds, with an ability to kill multiple people with a minor movement of the wrist.

Someone riding on a bicycle going 22km/h has, without exaggeration, less than 1% of the momentum of a car going 60km/h, and 1/2500th the amount of power. They have orders of magnitude less capacity to cause harm to anyone.

Appropriately, and reasonably, they bear a lot less responsibility on the road and can be a lot more flexible with the rules. Similarly, pedestrians have even less capacity to cause harm so they enjoy even more flexibility. On the other hand, semi trucks have more ability to cause harm and so have to contend with even stricter regulations, licensing etc. Commercial aircraft, stricter still.

Traffic laws and infrastructure in North America are almost entirely put in place for the benefit of cars and ignore the existence of all other modes of transportation. I submit that the North American legal and physical environment are just flat out broken, unjust and illogical when it comes to cyclists (as well as pedestrians to an extent). It really is reasonable that someone on a bicycle should enjoy more flexibility than a 3 ton SUV. The fact people are so upset that cyclists would behave any differently than cars despite being completely different is a great achievement of motorists and the auto industry to manipulate our culture, to force everyone to navigate society on their terms for the benefit of cars, to the point of insanity.

The fact that you refer to bicycles as "toys" reveals that the real issue you have with cyclists is not the bullshit story you present, where you pretend that cyclists doing the same exact thing as every motorist does - rolling through stop signs - presents some danger to society. You simply hate cyclists outright, you don't care about their safety, and think they don't deserve any space on the road at all. You just don't care about people who want to, or have to get around without a car. Your motivations are selfish and you should feel bad about yourself.
> photogenic

Maybe I am taking crazy pills, but even Unabomber at his unshaven peak (far from what most people would consider photogenic) was appearing more sane and photogenic than Holmes in her own promo photoshoots.

Agreed with your ultimate conclusion though. No matter how you stack the cards here, I had a gut feeling that she would make it out just fine, with Sunny being scapegoated as the "manipulator". Don't get me wrong, I believe he deserves at least just as much blame as Holmes. But he stood no chance.

Re Datalog syntax: yes, the "composability" is the main reason that I decided to adopt it as the query language. This is also the reason why we made storing query results back into the database very easy (no pre-declaration of "tables" necessary) so that intermediate results can be materialized in the database at will and be used by multiple subsequent queries.

I was wondering why this answer was rubbing me the wrong way and I realized it is because your answer shows a complete lack of empathy for "the other side". I have worked on warehouses and it is complicated.

>This says volumes about what they think about you and worse, what they think about their business and the problem at hand.

Why is this bad? If someone who is not technical, asks you to explain in detail about how the networking is setup and why is it not possible to just rewire the entire network to support something small, I wonder what your answer would be..

Operations managers in warehouses hone their skill over many years, running a large, very variable labor force efficiently. There are many variations over every single process and they have to keep the flow going while people come and go. If you cannot deal with an abstract request without asking everyone undergo "digital transformation", maybe you are in the wrong business.
Who is against a free government ID? I never heard of such opposition.
Back circa 1994, I was getting e-mail by dialing in to the Boulder Internet Coop via UUCP. They were really experienced Unix folks (Trent Hein, Evi Nemeth RIP), running Sun. At one point, the uucp queue got big enough (I believe from machines that were connecting infrequently or maybe not at all), that the directory holding all those files couldn't be scanned in less than the UUCP timeout. All the while I was paying long distance rates (remember those) to sit on the line idling.

I had recommended they switch to using Taylor UUCP, because it splits the queue directory up into a hierarchy. They said Taylor wasn't mature enough, but I asked Ian Lance Taylor about it and he laughed and said "<THE major commercial UUCP provider> doesn't seem to agree." :-)

I've always heard that Kermit has really great protocols for handling horribly, horribly bad modem connections. I had at times wondered if a kermit UUCP protocol would have been useful.
My initial impression is NOPE, and the fact this cloud architect is pushing you towards azure functions says a lot. The run on windows, take forever to cold start but do work ok for background processes. Given you mention user facing endpoints, prepare yourself for 15+ second cold start times while they boot a windows VM for your function, and no private subnet for the functions either. The answer to this is a super expensive "Premium Plan" which basically just rebranded app service which runs the VM's for you full time at double the price. I have used them and am not an azure functions fan myself.

In the azure world, a more modern option going forward is azure container apps which just run docker containers, but you still will have 8+ second cold starts and will need to run at least a single instance full time, but it's cheaper than functions premium. Also would suggest looking at an evented architecture using dapr which is built into ACA. In the GCP world cloud run is frankly amazing.

I am working on a large (for one person/me) project that requires a bunch of skills that I didn't have when I started, so I kind of made a dependency tree and I've done basically JIT learning as I go through the project. I had to learn how to design thing X, which requires learning tool A, then to fabricate thing X I had to learn skills Y and Z, which required etc. I also knew I had unknown unknowns so the tree expanded as I went. You learn all this new stuff and the todo list has gotten bigger!

For learning in any new-to-you large context without a structured curriculum it'll be a yak shaving adventure. But occasionally checking your to-learn list you'll realize that you _don't_ need some element you thought you did because you've found an alternate/easier path, so be on the lookout for opportunities to prune the dependency tree.

If you're self-teaching a big new subject area you're going to encounter unknown unknowns and your objectives will change while learning/doing, keep your plan evolving based on what you learn to keep moving forward.
