Being compelled to issue a land acknowledgement-- rate my response

At a recent meeting, I was asked to deliver a land acknowledgment and was informed that doing so was compulsory. I have concerns about compelled speech and freedom of expression, which I intend to address separately at a later time. In response to the request, I prepared the following statement: "We acknowledge that the Coquitlam area has long been home to Coast Salish peoples, including kʷikʷəƛ̓əm (Kwikwetlem First Nation), the primary nation of the Coquitlam River watershed, from which the city derives its name meaning “Red Fish up the River.” The region also has longstanding ties to neighbouring nations including səlilwətaɬ (Tsleil-Waututh Nation), the “People of the Inlet,” and q̓ic̓əy̓ (Katzie First Nation), whose ancestral connections extend through the Pitt River and surrounding areas."

Like much of British Columbia, questions surrounding Indigenous rights, title, and territorial boundaries remain part of ongoing legal, treaty, and inter-nation discussions within Canada’s constitutional framework".

In all honesty I have a problem with land acknowledgments as they grossly oversimplify the issues going on, and generally I feel are disingenuous while undermining Canada and the institutions they are coming from. How did I do?

32bit Sam21D based Max31856 4 channel Thermocouple based board for types (B, E, J, K, N, R, S, and T) - Playing with fusion

4-channel universal push-pin style SAMD21/MAX31856-based thermocouple board displaying real-time temperatures (~29.7 °C during Type-T thermocouple testing).

I originally received this board from Playing With Fusion for use in a cloud chamber project, although the process quickly became far more involved than expected. The included SD card appeared to be either counterfeit or damaged during shipping (possibly due to ESD), and the board itself had entered a locked state via the microcontroller’s FLOCKDOWN protection mechanism after detecting excessive current draw.

The onboard microcontroller is a SAM21D, which uses the FLOCKDOWN bit as a safeguard to prevent permanent damage under fault-current conditions. After several attempts, I was able to recover the board using a Teensy 4.0 running a SAM unlocking utility based on the GSTUB library, along with the BOSSA flashing tool. This allowed me to disable the protection fuses, fully reset the board, and reload the factory firmware. in the mean time playingwithfusion sent me a new board which was kind of them.

Unfortunately, I found the stock firmware unsuitable for accurate measurements below 0 °C, which was a significant limitation given the intended near cryogenic application. As a result, I developed a completely custom firmware solution using the Arduino IDE.

Because the system was designed for low-temperature and cryogenic work ( actually intended for use in a 20x20cm cloud chamber), I selected a Type-T thermocouple for testing and calibration. So far, the system has been tested successfully down to −120.78 °C with an observed accuracy of approximately ±0.15 °C. In cloud-chamber use, I won't be going below -60c. The firmware supports real-time temperature display, updates every 200 ms, selectable thermocouple types (B, E, J, K, N, R, S, and T), and full SD card logging. All settings and controls can be accessed directly from a Samsung Galaxy S24 Ultra over a serial connection running at 115.2 kbps wired or via computer. Display temperatures display in deg C , deg F or K on a high contrast 2.42" OLED display of SPI interface.

For those growing temperate timber bamboos -- Fertilizers

for those of you who are growing larger timber bamboos, what fertilizers are you using to maintain your groves/forests health? Make sure to put NPK down as well.

I have been experimenting with 18,6,12 and 24,5,15 and both gave good results. I used to use 34,0,0 but that is no longer able to be purchased without AG certification. This gave me excellent results

Weird issue with the magnetometer after recent OneUI8.0 security update

I have no ability to get any sensor data after the recent OneUI8.0 security patch on April 6th. I am running Android 16. Any ideas how to clear this error/ anyone encountering this issue before? compass indicates the sensor is not reporting at all. I have exhausted all diagnostic tools.

This grove is part of several large private bamboo plantings located about 5 km outside Gibsons, BC, not far from Sechelt. The bamboo is almost certainly Phyllostachys bambusoides, as the culms are remarkably straight and have very thick-walled wood. According to local rumor, the original bamboo came from a private nursery on the North Shore that once had a massive grove of it.

Some of the culms here are around 50–60 feet tall and approximately 5.5 inches in diameter, with not a single culm under 3.5 inches. It’s an impressive stand. The southern Sunshine Coast gets good summer heat and has relatively mild winters, falling roughly within Zone 9a/9b.

Here's a lovely "grove" of Phyllostachys Vivax as an architectural accent that brings organic texture, warmth, and structural elegance to a modern design. This used to be part of the Shangri-La Hotel now owned by the Hyatt. Grove concept designed by PFS Studio. Some of the newer culms are 50-60ft now x 5.5in dia. It is growing very very well

I was at the UBC botanical gardens today and I came across the now expanded maturing grove of P.edulis undergoing a mass emergence event.

Some of these culms are 3-4" dia and ~40-50ft tall perhaps. I have seen Moso in its native environment shoot from March to May, in Osaka Japan, as well as in Kyoto ( Sagano, Arashiyama locality) as well as in Damyang-gun, Jeolla-Namdo in S.Korea as well. This is my favorite bamboo of all, the king of kings. It is the largest temperate timber bamboo on earth. This one takes several decades to get to full size. ~25years

look at that canopy. Beautiful

new 3.5\" dia shoot.

What a gorgeous specimen!
