reaction notes

Relevance of a good facilitator is made clearer when the facilitator is not effective
* not just saying the rules and explaining the rules, but being able to address situations where the rules are violated

What is the purpose of rules that are not enforced?

*****************

Relevance of barriers (financial, temporal, location) as a way to ensure safety, comfort, and progress.
The first section of meditating for 30 minutes can be a barrier/filter, but only if attendance is required. Otherwise people will just show up for the "fun" part.

If you offer a space that's heated and there's free food, need to think about more than just who you want to show up. Who would show up that would take advantage of that offering? And what consequence would there be to that exploitation?

If I don't feel safe, I can't feel comfortable. If I don't feel comfortable, I'm not going to be playful or curious or open or vulnerable.

relevance of location of meditation practice

Location matters.

Not just acceptable behavior, but expected. Purpose built

But building a building and maintaining it costs money and can be a distraction. Especially when people start prescribing meaning to the physical structure. 

Getting money from people takes time and persuasive arguments about value.

CMS 50D+ pulse oximeter

I purchased a CMS 50D+ pulse oximeter from Amazon for $38 in 2015.

How a pulse oximeter works: https://www.howequipmentworks.com/pulse_oximeter/

USB

The first time I plugged the device into my USB port, dmesg reported the following:

[  113.192067] usb 4-1: new full speed USB device number 2 using uhci_hcd

I'm not sure how to poll the saved data, or get live data from the USB device

Ubuntu 

In Ubuntu, I installed SleepyHead
http://sleepyhead.sourceforge.net/wiki/index.php?title=Main_Page
http://jedimark64.blogspot.com/p/sleepyhead.html
http://sourceforge.net/projects/sleepyhead/
http://sourceforge.net/projects/sleepyhead/files/Releases/Linux/

sudo dpkg -i sleepyhead_0.9.2-1_i386.deb
SleepyHead
I can view live data and save data to file.

cd ~/Documents/SleepyHeadData/Profiles/
go into the most recent directory, ie
cd CMS50_560ee6c6

Although I am able to see the save files, they are binary and I cannot read them.
SleepyHead hits a segfault

Windows XP

The pulse oximeter came with a mini-CD with application software for Windows. I installed the SPO2 Assistant exe, which included a CP210x USB to UART Bridge Driver Installer.

Two programs are installed: "SPO2 Review v1.5" and "SPO2 manager v1.5"

"SPO2 manager v1.5" automatically saves the live data to "C:\program files\Sp02\Data" in both binary and CSV format! Yay

observations from hosting Tea with Strangers

number of participants sets the vibe

• 1 person (plus the host) is direct and focused. There's no where to divert attention or take a break
• 2 people (plus the host) is my ideal group size -- small enough to feel intimate, and small enough to prevent splitting conversations; large enough to allow breaks for participants
• 3 people (plus the host) is the first group size where splitting the conversation is feasible. I find concurrent conversations distracting.

My first goal as host (usually stated explicitly at some point during the interaction) is to identify harm and address it directly. That includes both the person doing harm (intentional or unintentional) and the person being harmed.

While that criterion is necessary, it is not sufficient for me to feel I am getting value. I want to feel connection with the participants. I have a bag of tricks for building intimacy, but I feel it could be imposing (given my position of power and responsibility) on attendees to use it.
