holdenk··on 15-minute at-home Lyme disease tick test
And it's relatively easy to get a prescription for since it's a PEP drug for high -er risk sexual activities.

We'll be running an Apache Spark community sprint centered on helping folks get their first PRs into the Apache Spark project on March 13th (Friday) from 12:00-7:00 PM at the Snowflake Bellevue Office :)
holdenk··on Smallpond – A lightweight data processing framework built on DuckDB and 3FS
Admittedly just one part of the insurance paperwork but we're working on automating appeals at Fight Health Insurance / Fight Paperwork :) ( https://www.fighthealthinsurance.com/ / https://www.fightpaperwork.com/ )
holdenk··on Show HN: Make your health insurance company cry too Fight Health Insurance
I created a new AI tool ( https://www.fighthealthinsurance.com/ ) to generate health insurance appeals. The code & model are both open ( https://github.com/orgs/totallylegitco/repositories & https://huggingface.co/TotallyLegitCo )
holdenk··on Sony software updates breaks movie theater projectors
I think a world without any form of meaningful protection or regulation sounds very dystopian and not like one I would choose to live in under our current capitalist society.

Even the author of the “theorem” you cite indicated that he didn’t believe it to be practical.

holdenk··on My fifth year as a bootstrapped founder
Only the flipside, QSBS shares have some great tax advantages if you think you might have a traditional "exit" at some point.
holdenk··on How to store your app's entire state in the url
I did something similar using Racket's (nee PLT scheme) web programming module ( https://www2.ccs.neu.edu/racket/pubs/hosc07-sk-mf.pdf ) back with an app that got on slashdot -- https://github.com/holdenk/web2.0collage

The theory was wonderful (yay! stateless load balancer etc.) but in practice browsers at the time were less than happy with trying to store that much state in the URL.

holdenk··on Musk’s Twitter purchase was a leveraged buyout
This matches the "cut infra cost by 1` billion" demand he made as well - https://www.reuters.com/technology/musk-orders-twitter-cut-i...
holdenk··on New OSS Satellite Communication Device
If you've wanted to add satellite communication to your IoT project but traditional pricing has turned you off, we're kickstarting a new device (using an existing LEO constellation).
holdenk··on Ask HN: Why are distributed systems so polarizing?
This is so true. Hire a bunch of senior engineers to solve junior level problems and they'll turn the junior level problems into senior level problems :p
holdenk··on Intel's “Cripple AMD” Function (2019)
Huh I had wondered why I saw so many Python packages blacklist MKL now I know why.
holdenk··on USB-C hubs and my slow descent into madness (2021)
I like the tear-down approach, I wish it was more common for these devices to say what chips they used.
holdenk··on Support open source that you use by paying the maintainers to talk to your team
If anyone wants to chat about Spark or related stuff I would totally do that for money.
holdenk··on Feynman’s advice to W&M student resonates 45 years later (2020)
As an author I _love_ feedback especially things where I can fix it / improve it.
holdenk··on Resources to encourage children to learn to code
I've been working on a book to teach kids data parallel distributed computing with Python and PySpark (Distributed Computing 4 Kids), if anyone wants an early review copy let me know :)

or give your e-mail at https://www.distributedcomputing4kids.com/ :)

holdenk··on Why and How I Got My Own ASN
So they don't do dedicated boxes (sadly), they rent by the rack (including 1gb of transit + 15A power). https://he.net/colocation.html has the info. If you just want a dedicated box that isn't drawing a lot of power I've probably got some room in my rack and we can chat (and I imagine some of the other BGP for fun group folks are in similar positions).
holdenk··on Why and How I Got My Own ASN
If anyone is in the bay area and wants to run physical hardware and peer with folks, FCIX down in the HE facility in Fremont is very welcoming to small networks and doesn't have port fees (although you do need to be in the HE facility).
holdenk··on Daddy isn’t coming back
My partner and I talked about our health (and mental health) in the context of deciding if we wanted to be parents to a kid. I like to think that's a normal enough conversation to have.
holdenk··on “It's open source! We’ll let our customers fix it.”
Apache Beam _can be_ but this person is talking about using it inside of Google (e.g. as the Dataflow API) and with a Google service. I think the comparison is on the money. That being said I think the best way forward would be both google cloud support & a JIRA ticket.

Although, to a degree, I think the authors complaint about Google's mentality towards open source is on the money, a lot of the OSS work is understaffed with the theory that the community will pick up the slack, even when the primary users of the OSS project would be Google customers.

(Full disclosure: I work on Apache Spark for my day job, have previously worked on Apache Beam for my day job, and have friends who work on Bigquery so my world view is maybe skewed).

holdenk··on ‘Great Resignation’ gains steam as return-to-work plans take effect
So one of the things to remember about Google is the desire to increase attrition of senior employees (e.g. those with the most flexibility to move elsewhere). It's.... weird, but it would totally match.
holdenk··on Airflow 2.0
Congratulations on the release :)
holdenk··on Trump administration announces overhaul of H1B visa program requiring higher pay
I've worked at small companies while on an H1B, if you look at the who's hiring posts on HN I think you will see many places willing to sponsor H1s, so it's not just big companies.
holdenk··on AWS Ruins Own Attempt at Sabotage
So serious answer:

I worked for Amazon because they recruited from my University and it was my first after graduation job. I'd had some internships, but I didn't have a large network or a lot of options.

holdenk··on San Francisco, Silicon Valley rents plunge amid downturn
Except in places like San Francisco with rent-controlled housing.
holdenk··on Crypto Fund II
It was my understanding that in the current system merchants tend to eat the cost of fraud under our current system (see charge backs, rolling reserves, etc.)
holdenk··on The untold origin story of eBay that I lived (2018)
So I've seen several folks say that they do.
holdenk··on The Paxos Algorithm, or How to Win a Turing Award
I'm starting with a book designed to teach kids Apache Spark using garden gnomes ( http://www.distributedcomputing4kids.com/ ) and depending on how that goes I want to branch out and do some other topics.
holdenk··on Nginx to Be Acquired by F5 Networks
Dataflow it's self isn't open source. Beam is not open source Dataflow, however you can use the Beam SDK with Dataflow as a runner.
holdenk··on Canada facing ‘brain drain’ as tech talent leaves for Silicon Valley
When I graduated and tried to find work in Canada multiple firms told me I was "too weird" and "should move to California", so I did and I'm super happy that it worked out the way it did -- but I still feel sad about having to leave my home country to be my authentic self.
holdenk··on Engineers Should Blog
Some of the highest traffic blog posts I've written have been on the "entry-level" side of things.
