jacobmarble··on Court Records Should Be Free
Embarrassed. PACER is $0.10 per page, Idaho courts charge $1.00 per page.
jacobmarble··on Court Records Should Be Free
Oops, I should know better. Thanks for the correction.
jacobmarble··on Court Records Should Be Free
PACER is for federal courts, price is $1 per page.

I'm being sued in the State of Idaho, where the price of each page is $10.

jacobmarble··on Using Kagi Search with Low Vision
One more reason to love Kagi Search.
jacobmarble··on Show HN: Maths, CS and AI Compendium
Yeah I’d love to study through a simple website, I guess that’s gitbook? I haven’t used it before.

To the OP: Do you need help generating a little static website? I did this with Claude the other day, could figure it out for you repo for sure.

jacobmarble··on Show HN: Maths, CS and AI Compendium
So good!

I got a math minor with my CS major 15 years ago, and just started sending applications to MS CS ML/AI programs. I really need this now to relearn linear algebra etc, and your site is really bringing things back quickly.

I’m not doing the coding exercises (yet), that’s just me for now, no feedback there.

I did have some feedback when I was reading last night, will send a PR when I have time.

Kudos, friend!

I’ve read chapter 1. 10/10
jacobmarble··on The Trinary Dream Endures
In digital circuits there’s “high”, “low”, and “high impedance”.
jacobmarble··on Ask HN: What are you working on? (October 2025)
I’m creating an electronic avionics sensor and display for experimental aircraft. I’m having a fantastic time learning about circuits and MCUs (I have a pure CS degree, zero background with EE stuff). I’ve been working on this in my off hours for over a year now, maybe someday it will be a product that people buy!

The current challenge is the display. I’ve struggled to learn about this part more than any other. After studying DVI and LVDS, and after trying to figure out what MIPI/DSI is all about, I think parallel RGB is the path forward, so I’ve just designed a test PCB for that, and ordered it from JLCPCB’s PCBA service.

jacobmarble··on Ask HN: What's a good 3D Printer for sub $1000?
I bought my first 3D printer six months ago, it feels as high quality as an HP printer, couldn't be happier.

jacobmarble··on Ask HN: Who Is the Best Paid Email Provider? Why?
I’ve been a Migadu customer for a few years. It’s a simple company with simple pricing, and I couldn’t be happier.
jacobmarble··on Ask HN: Do you still use search engines?
Same. I switched to Kagi over a year ago, and now every other search engine looks like a steaming pile of ads and slop.
jacobmarble··on LED's Efficiency Exceeds 100% (2012)
The title is click-baity, but the information is interesting.
jacobmarble··on A powerful free and open source WAF – UUSEC WAF
This reads like LLM generated text.
jacobmarble··on Don't make fun of renowned author Dan Brown (2013)
This reminds me of Jerry Seinfeld's comments about his critics in "Comedians in Cars Getting Coffee".

Summarizing, when the audience laughs, they vote about the quality of the bit. When the tickets sell out, they vote about the quality of his work. So, who cares what the critics say?

This might not make sense, but sometimes this perspective helps me (not a comedian, or anyone critics have ever heard of).

jacobmarble··on Qwen2.5-Max: The Next Leap in AI Innovation
This reads like it was written by an AI SEO bot.
jacobmarble··on Apache Hudi: an open data lakehouse platform
I've been working with Apache Iceberg for 18 months now. Everyone in the community seems to be going toward Iceberg, not Hudi.

jacobmarble··on Ask HN: Is ChatGPT down?
But there are dozens of us working today! Dozens!
jacobmarble··on Piccolo OS, a Small Multitasking OS for the Raspberry Pi Pico
I've been using protothreads on the RP2040 (Pico MCU) for task management.

The extensions available from Hunter Adams at Cornell are also very useful. In particular, PT_YIELD_INTERVAL() has been very useful for me.

jacobmarble··on Raspberry Pi CM5 is a faster, drop-in upgrade
Can you highlight the resources that you used to level up this way? I can design my own microcontroller boards, but the complexity of SoCs and required peripherals seems too much for this part-timer.
jacobmarble··on Transactional Object Storage?
If I had time, I'd like to implement an Iceberg catalog this way.
jacobmarble··on Supercharge the One Person Framework with SQLite
Yes, it's a long presentation. Here's a good answer to your question:

> So, yes, it is actually possible to run full-featured Rails applications in production, with no compromises on features or performance, all on a single machine.

In other words, "stop worrying and just deploy a single application instance".

jacobmarble··on Ask HN: Why aren't you solving real problems?
One way to frame the capitalist framework: The "private sector" seeks profit and the "public sector" seeks social stability.

I agree that the problems you describe are important. Most of them fall in the scope of "public sector" problems. I'm not working on those because I've chosen to work in the "private sector".

Adam Dunkels also wrote (most of) Protothreads. https://dunkels.com/adam/pt/
jacobmarble··on I got almost all of my wishes granted with RP2350
Please explain. What is a better alternative that could have been chosen?

I’m just happy to have one fewer component on my boards.

jacobmarble··on S.3819 – Shrinkflation Prevention Act of 2024
Is this what happens when I buy a box of cereal for $4 in 2014, and the same box of cereal for $4 in 2024, but the contents weigh 20% less in 2024?
jacobmarble··on The Law of Leaky Abstractions (2002)
> So the abstractions save us time working, but they don’t save us time learning.

I could say the same for programming with Copilot.
