One more reason to love Kagi Search.

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.

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!

In digital circuits there’s “high”, “low”, and “high impedance”.

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.

I bought my first 3D printer six months ago, it feels as high quality as an HP printer, couldn't be happier.

I’ve been a Migadu customer for a few years. It’s a simple company with simple pricing, and I couldn’t be happier.

Same. I switched to Kagi over a year ago, and now every other search engine looks like a steaming pile of ads and slop.

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).

I've been working with Apache Iceberg for 18 months now. Everyone in the community seems to be going toward Iceberg, not Hudi.

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.

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.

If I had time, I'd like to implement an Iceberg catalog this way.
