    Since it hasn’t been mentioned yet: Matrix. It is a federated chat protocol, so you can self host to control your own data. Major projects like NixOS use it.

    It’s funny you put it this way; arguably privately held companies are much better at this, but there are few large companies that are privately held.

    I've often mused that a fat lot of the enshittification we all bemoan could be solved if we can just figure out a way to properly incentivize companies to be more interested in the products and services they provide rather than stock price and gross profits.

    My same70 (Duet3D 6HC) speedup got merged into Klipper! Additionally a new package and module for prometheus-klipper-exporter got merged into nixpkgs/NixOS!

    My project for the last few days has been getting the LIS3DH accelerometer on my printer working over I2C. The Duet3D Toolboard 1LC has one onboard, and it makes sense to have an implementation. Here is that work, will need some minor refactoring once another set of commits goes into Klipper to get merged. It has been a moderately successful couple of weeks for my 3D printing hobby.

    Following up on my last post, I managed almost four times speedup for Klipper on the same70. Here is the change. Figuring out the DMA hardware was a massive pain.

    Next I might get the LIS3DH working over I2C so my toolboard has a functioning accelerometer.

    Yeah - I listened to it when it released and wasn’t liking it initially, but it grew on me after a few closer listens.

    Well, Klipper currently runs my printer, and I (with a decent amount of debugging help from another developer) added the Duet 1LC support to it already - I wanted to try Klipper out rather than RepRapFirmware due to some issues I was having with RRF. I just got annoyed that I can’t run higher microsteps on the 6HC and started looking into it.

    And you are not far off - there is a GCC annotation that is also used for hot path functions in Klipper (I think, since the linker mentions RAM functions) that I believe you are talking about. This is a little heavier, since it is not so hardware agnostic as that.

    After sitting down for a few hours and going over the microcontroller manual, then confirming with another developer, I realized that the ATSAME70 (Duet 6HC) runs slowly in Klipper because every instruction is fetched from flash memory, over a bus that is running at half the frequency of the processor. That is, the chip runs at 300MHz, but is really running at a maximum of 150MHz due to the bus (even RAM access happens over this bus), and probably much slower because we have to wait a certain number of cycles to read from flash. I started tinkering with enabling caches, but realized that Klipper is small enough to fit entirely in the Instruction Tightly Coupled Memory (ITCM) on this chip with room to spare. My current plan is to try loading Klipper into flash with virtual memory addresses that point to the ITCM, then using the Direct Memory Access (DMA) controller on the chip to copy the entirety of Klipper into the ITCM before enabling the ITCM. I have to use the DMA hardware because there is a seamless remapping that happens from the ITCM addresses to the beginning of flash memory when the ITCM is disabled, but DMA can write to those addresses without getting remapped. I’m trying to minimize modifications to the linker script as much as possible, to make it easier to merge upstream. After this I will try to enable the Data Cache in the processor, because all of the data should simply fit directly into it, and then everything will be able to run at 300MHz.

    My point is that you are discounting the size of the market for flavorful alcoholic beverages, this reads as an assertion of that to me. I don’t really want to argue semantics though, so okay.

    Very few people enjoy alcoholic beverages for the taste alone. It's disgusting.
