I use mosh over WebSockets to have a long lived connection to my home network. I bet I could simplify out the WebSocket-to-UDP proxy by leaning into tailcat's dataplane and just speak straight UDP.

I get IVIG 3x / week for a primary immune deficiency I’ve had since birth. For my dosage, it’s billed weekly at a rate of ~$32K of which my insurance company pays around ~$3K. I hit my max out of pocket the first month of each year and

UNIX systems programming can be accomplished by looking at man pages and referencing kernel / user land source code. I find something cathartic writing C applications and tools. Perhaps I should seek professional help.

Who says they can't see the URL? A sufficiently motivate government would probably be able to create forged certificates and mass interception isn't really out of the question. Especially with browsers homogenizing on fast ciphers

I find it impossible to replace a legacy system without first understanding the legacy system. It's easy to say "X is old" or "X sucks at Y" but keep in mind that applications have a strong survivor bias. Ask yourse

I'm a new parent and I need to track when my son eats/poops/pees etc. There are times when my hands aren't available. I built a tiny "app" that just records these things to a google spreadsheet for me. I also l

It's a hard problem to determine the repeat purchase cadence of a product. At one end of the bell curve you have items re-purchased frequently, e.g. diapers or grocery, and on the other end you have items that are rarely repurchased. I

Cool! I would suggest changing the branding to "a simple job board for people with disabilities." For many people the disability is a part of who they are - it's not how they self identify. See some of the existing non-profit

I was really hoping for an retrospective about a multi-armed bandit learning algorithm that ran in production but never experimented, effectively yielding a "zero-armed bandit".

Is it used to derive separate HMAC and AES keys or is the same key used in both contexts?

My discrete math and logic undergraduate course was in Coq. It was a brutal way to learn the proof process at first but it was worth the investment by the end. It's the logic equivalent of TDD. If you are interested in computational lo

I wrote a similar system for C# - we had three queues per application, work, delay, and error. In our system, the deferred queue used per-message TTLs that would push messages back onto the work queue. This allowed us to inspect the deferre
