TFW they give you invite codes for Bluesky but you run short of peeps that aren't there already.
For those wondering, YES I'm a UNIX nerd/user and YES I still resent IBM replacing control with capslock and putting control in a RSI inducing location. Fortunately QMK based keyboards let you hard remap the key and add Fn+Control for capslock if you REALLY want to have caps on all the time.
My keyboard/keycap educations continues apace! What I've learned is that the default keys that come with my Keychron keyboard (Q3 Pro) are "SA" profile and the "CAPSLOCK" key is 1.75u with "R3" pitch. And with @jesse's help found the ONE vendor that makes the one I think I want. AND they will let me order just this keycap. So we'll see if they meet my needs.
I really like my Keychron Q3 pro, but would like it better if I could replace CAPSLOCK with CONTROL. (the software does this, need the keycap) I have a set of keycaps I purchased to make this switch but they are thinner (not as tall?) than the stock caps and that hurts accuracy (bigger tops) and feel. Recommendations for key cap vendors?

It looks like large companies are starting to release Qi2 chargers. Does anyone have a source for just the Qi2 electronics?

I want to integrate Qi2 into some #woodworking and #3dprinting projects.

I already searched AliExpress, no luck.

Boost for reach!

At this point, I've been running an annealed PLA-CF fan shroud on my KP3S Pro V2 for a week, including a 12-hour and a 10-hour print. Literally not a single trace of deformation anywhere, even on the parts near the hotend. Some screw loosening did happen, but we're talking something like an eighth of a turn.

I'm gonna call _that_ experiment a success.

Full SDR implementation of LoRa in GNU Radio.

https://github.com/tapparelj/gr-lora_sdr

GitHub - tapparelj/gr-lora_sdr: This is the fully-functional GNU Radio software-defined radio (SDR) implementation of a LoRa transceiver with all the necessary receiver components to operate correctly even at very low SNRs. This work has been conducted at the Telecommunication Circuits Laboratory, EPFL.

I am finally tuning my home network for bufferbloat. I've managed to move from a C to an A grade on the Waveform test tool.

My home router is pfSense and my provider is Comcast.

I followed the online instructions, and found that it is important to configure for 95% of up/down rated speeds rather than full rates.

Also - it is important to test using a wired computer, not wi-fi.

My home wi-fi (a mesh system) definitely has bloat issues. I'll try to deal with that next.

Eventually I'll write and publish a How I Did It note.

My Plotter has found a home. So happy for it.
Well I put my plotter (HP750C+) up on Craigslist (https://sfbay.craigslist.org/sby/sys/d/sunnyvale-hp-750c-large-format-printer/7656016495.html) but it doesn't seem like anyone is interested in it. This makes me sad.
