Cleaning grease build-up on kitchen hood exhaust fan filters - baking soda solution
About twice a year, the kitchen stove exhaust fan grease filters get clogged with greasy "gunk"
I used to try to just use dish soap and a dish brush, but the brush would just load up with the gunk, and not really remove it from the filters well, and now the brush would likely be thrown out.
So, I did some searches, and a few DIY folks said to combine baking soda with dish soap and hot water, then soak the filters in that solution.
I was skeptical, but tried it. It works!
In a large plastic tray, large enough to cover a filter with about half an inch of water, put enough water to cover the grease filter completely. Hot water works best.
Add about 1/4 cup of baking soda to the water. Stir to dissolve.
Add a tablespoon or two of dish soap to the water. Stir to mix in.
Place the greasy gunky filter into the solution, such that it is immersed completely.
Soak the filter in the solution for one hour.
After the hour has elapsed, you should see the water darkened with grease particles. Some of the gunk may float to the surface. Some of the gunk may drop to the bottom of the container.
Using a dish brush, with light effort rub all over the outside of the grease filter. The idea is just to knock loose the grease residue that has been chemically "attacked."
Rinse the filter with fresh water, then inspect. If still too gunky, discard the now-dirty soak liquid, make a fresh batch, and put the filter in.
Do as many one hour cycles of soak, brush, rinse, inspect, until the grease filters are clean enough.
At the end of the last cycle, rinse the filter(s) with fresh water very well, to remove any soak liquid. Then dry and reinstall.

SETI - low hanging fruit next-step idea - active broadcast
I would like to see SETI receive funding and infrastructure to begin actively sending radio transmission broadcasts to candidate star systems, in the hopes of receiving a response.
It seems a low-hanging fruit next step. To try to determine if there are other civilizations out there, that are at or above our level of technological advancement.
It seems it would not be very expensive. I few tens of millions of dollars per year, globally, to "rent" time of radio telescopes that can support being used for broadcasting.
Perhaps, like in the book "Contact" by Segan, the message would simply be continuous wave pulses of counts. Perhaps prime numbers 1, 2, 3, 5, ..., 11. Each pulse one second long, two-seconds between counts. Then recycled.
Ideally science would have a best-guess on radio frequency to use. And have enough participation so that the broadcast power of the signal had a chance to be strong enough to be detected in the target system. And have as many participating transmitters beam to a candidate system for perhaps a week, then move to the next candidate, etc.
Of course, once there had been enough elapsed time for the system to receive the signal and perhaps transmit something back, the 2nd Phase would be to begin surveillance of the systems transmitted to, for a response, after enough years had passed.
It's still a desire, that in my lifetime, that we would discover proof we are not alone in the cosmos.

Debian 8 stable == > Debian 9 stable installation
Went to the Debian website. Downloaded the Debian 9 netinst ISO file
Installed the ISO file to a recordable CDROM using brasero
Moved my PC closer to my internet connection. Connected it to the internet using an ethernet cable.
This PC, a Gateway laptop, doesn't have a wifi driver that will allow wifi installation. So it is a two-step process: 1. install via ethernet cable. 2. Install wifi (b43) driver.
Put the netinst CDROM in the CD drive of the PC. Rebooted.
Followed the prompts. Did a default Debian install, kept it simple. A single partition for all the folders (it's a laptop).
...after about two hours...
Success!
Post-installation
Installed aptitude.
Installed sudo.
- as root ran addgroup myUserName sudo
- *** you have to reboot before myUserName can run sudo commands ***
Installed the b43 wifi driver
- as root, updated the /etc/apt/sources.list file to include contrib
- as root, ran aptitude update
- as root, ran aptitude install firmware-b43-installer

Legal recreational cannabis - dispensary resupply run
Goal: cost savings.
Looked at the weedmaps online menu for my favorite trusted dispensary: Cornerstone Collective.
Realized that tincture edibles provided more mg of THC and CBD per dollar.
Wrote down some products and prices, to do my THC:CBD 2:1 ratio regimen.
Went near opening time, just after 10am, which was an excellent choice: they are not too busy in the early morning, so was able to in-and-out quickly.
Showed the salesperson what I had written down, and what I was trying to do (cost savings but still wholesome products with a good reputation).
They brought me two tinctures.
One tincture was Mary's Medicinals THC tincture. Provides 1000mg THC per bottle. Cost was fifty dollars.
The second tincture was Mary's Medicinals CBD tincture. Provides 500mg CBD per bottle. Cost was fifty dollars. The packaging also mentions that one drop provides approximately 2mg of CBD.
With all the taxes, the total purchase price was one hundred and thirty-seven dollars.
Both tincture bottles contain a net of 12.5grams of tincture. So it looks like each Session will be a single drop of liquid from each container.
If I did my math correctly, I will get about two-hundred servings of CBD per bottle, as 2mg is what I usually consume per Session. It seems the THC will be about 4mg per drop, as the concentration of THC is double in its bottle.
So approx two hundred Sessions of 2:1 THC:CBD for one hundred and thirty-seven dollars. Works out to about sixty-nine cents per Session.
Since I currently still only do one Session per night, I should be able to enjoy a great night's sleep for a little over six months, before the need to do another dispensary resupply run
EDIT 2019-04-06
Changed the amount of THC tincture I consume. Now am having two drops of the THC tincture with one drop of the CBD tincture. Seems one drop of the THC tincture was not enough to prevent waking up pre-dawn too many days this last week.
With two drops of THC tincture combined with one drop of CBD tincture consumed around 8pm, sleep onset is around 10p to 11p, usually waking up around 6am or so.
EDIT 2019-08-18
Still doing 1 drop CBD plus 2 drops THC after dinner, for a great night's sleep. Have felt no need to adjust the dosage higher. The CBD bottle is currently about half full. The THC bottle is currently about one third remaining.
It may be that staying with this cannabis tincture brand and the number of drops I do, means only having to visit a dispensary and resupply every six months. *Huzzah!*
