Kind of difficult to give recommendations on where to start for resoldering, but my first hunch would be cold solder joints somewhere. I have a Kyria from splitkb that I assembled myself that had spotty LEDs on one half which turned out to be a cold joint on one of the surface mount underglow LEDs. Also had no key presses registered on a row that turned out to be a cold joint at the MCU.

As for general troubleshooting recommendations, if you can get a board schematic that would be immensely beneficial for your efforts as it would show how and to what pins of your MCU everything is connected. With that you can try to identify where the fault might be occurring (e.g. LEDs die after LED 5 in the chain) and focus your efforts before/after that area.

Failing the board schematic, you may be able to just visually see where the traces connect back to on the PCB, or you could probe it out using continuity mode on a multimeter and reverse engineer the connections.

Another thing that may aid in diagnosing where the issue lies with the double key presses is figuring out how the key matrix is laid out. For example if you're receiving double presses on only some keys in a single row or column, the issue lies in either that row/column or the MCU pin they connect back to. Again, the board schematic would be really helpful in this regard.

Best of luck!

Crashing and burning (in a non-production environment) is an excellent motivator to develop necessary skills; being unafraid to break things and fix them when they inevitably break helps you get a deeper understanding of how the systems work, for what it's worth.

I think this may more for acute vertigo, but have you tried the Epley maneuver?

I've always understood the concept of compilers turning high-level languages into assembly for CPUs to actually execute, but I've never really considered how that sausage is made.

In this video series Pixeled pulls back that curtain and describes the logic and rationale on how compilers are actually created for high-level languages.

This appears to be a variation of the "standwich." Please see the attached for an example.

I loved that book growing up and was so excited when the movie was coming out (on my birthday!)

To this day, that movie is the only one I legitimately walked out of. It was such a terrible adaptation.

Running an RKE cluster as VMs on my ceph+proxmox cluster. Using Rook and external ceph as my storage backend and loving it. I haven't fully migrated all of my services, but thus far it's working well enough for me!

I don't know how I feel about this personally. On the one hand, I feel like this is a privacy win for those who want it: no watch history means no algorithmic recommendations and (presumably) less data collection for those users. On the other hand, I personally really enjoy the recommendations that YouTube makes for me. Maybe it is the wide variety of content that I watch, but I'm honestly very pleased with the recommendations that YouTube provides. That being said, I feel like the opt-in to algorithmic recommendations is a good thing overall, however I am personally going to leave my watch history enabled.

Good Afternoon Everyone,

I am looking for a goldilocks tactile switch it seems. I want a tactile switch with the tactility of a Zealios v2, with the sound of a Gazzew U4T.

I love the P-shaped bump that Zealios v2s provide, and it helps me with my typing accuracy, however I prefer the sound profile that the Gazzew U4Ts have.

People swear that U4Ts are extremely tactile, but I just don't feel it. I think that it's in part due to the fact that the tactile event is more rounded ("D" shaped), or that the event occurs over a longer travel distance coupled with the reduced travel of the long stem. That being said, I love how the U4Ts sound and would love to find a switch that feels like a Zealios v2 but sounds closer to a U4T.

Open to any and all suggestions, thanks!
