This is the kind of stuff I enjoy posting. It's not intended to be scary, so I'm not waiting for next Moody Monday.  And, yes, I'm posting at 4am today because my rambunctious cat woke me at 1am and I was unable to get back to sleep.  Welcome to my insomnia.

Horshack from Mr. Kotter tv show, raising hand and saying "Ooh! Ooh! Ooh! Ooh!"I asked yesterday for automated ways of dealing with box elder bugs, maybe a bug zapper or something.  Well, somebody trained an A.I. to recognize cockroaches, then automated a laser to zap them dead.  (What could go wrong?)  Ooh!  Ooh!  Do box elder bugs next!

I've mentioned syncytia a few times already. An Australian professor tweeted this video of cells infected with SARS-CoV-2 (probably a BA.5 lineage) forming syncytia. You see cells clumping together and being joined by long connecting filaments. Look 2 tweets above this one for a higher resolution photo, but you'll have to zoom in to see the filament. This is one way that SARS-CoV-2 gets into new cells and tissues that it wouldn't normally infect via ACE2 pathways. It's really talented at forming these syncytia.  And now there's video!  :)

In another Twitter thread, someone points out that Blaschko's lines are visible in ultraviolet light, and since some animals (such as cats and dogs) can detect light in the ultraviolet spectrum, they might see us with these unique patterns on our body.

I got about 2 hours of sleep, followed by 3 hours without.  I finally came downstairs and turned on the computer at 3:15am.

I've been doing the rehab exercises for my damaged rotator cuff in my left shoulder.  My range of motion has improved a lot.  I can almost get my arm straight above my body!  The "resting" pain remains, though.  It's hard to sleep when you have non-zero pain... for almost 2 months now.

I've been trying some CBD+melatonin gummies for many days now.  They do nothing at all for me.  As much a waste of my money as the previous CBD drops that I tried in 2018, which I think is when I had the previous rotator cuff problem.  I also ordered a single dose of CBD+CBN+melatonin oil, and it actually did work.  I slept at least 10 hours that night. I think I need to order more of it.  I wish Minnesota would get off its lazy behind and just legalize marijuana already, so I could easily try better options than whiskey.  My liver and my waistline would both appreciate a healthier alternative to stress, pain, and insomnia.

I could use a series of good nights of rest.
  • No gunshots since Saturday night.
  • No crack house arguments since last Thursday, I think.
  • No insurrections for 2 weeks.  
My standards for "good times" are pretty low these days.  Once I get over this shoulder pain, maybe I'll have a better chance at finding some good sleep.  I think I'll play some computer games for a bit.  Drink some whiskey since the CBD was a flop.  Then hope for a few more hours of sleep.

gunshots nearby in Minneapolis 2020 June 23 around 2amIt was another rough night with gunshots a few houses away. I got about 3 hours of sleep. The violence has been bad here in recent days. They even did a special news segment last night about the weapons that actually harmed people. My house is at the far north side of their map. They failed to mention ANYthing about the many bullets flying everywhere that do NOT hit someone. It really is a #WarzoneInMinneapolis here.

As I learned last year upon self-reflection after "Engaging Across Difference" training at work, frustration can make simple-but-wrong solutions very attractive. Systemic changes are too slow, yet we need fast relief. I'm facing that problem again. I'm certain that we need both kinds of solutions here in my Jordan neighborhood of Minneapolis. I promised a post back in January, and someone at work asked me online today:

What are the immediate fixes to these problems?

There's simply no time to wait decades for system changes. Everyone in my area needs and deserves immediate relief from the stress of circumstances here. What does it look like to SOLVE some of the underlying problems instead of merely SUPPRESSING or RELOCATING the symptoms?

Drug-selling business:
Legalize everything.  If my crack house neighbors want to "play" at running a business, then make them actually do it.  1) When they have a dispute with a competing business, make them buy lawyers and advertising to solve it instead of literally killing their competition (and anyone else nearby).  2) Make them pay taxes to help rebuild the streets, sidewalks, fences, and trash cans for all of the extra car traffic and foot traffic they bring.  3) Calm them down by preventing their DEFENSIVE posture of hiding their business.  Instead, encourage an OPEN posture of advertising so they can establish a stake within the community for themselves.

Drug-buying customers:
Raise minimum wage and/or establish Universal Basic Income so people can afford to put food in their belly, keep a roof over their head, and keep clothes on their bodies (bare minimum survival standards) without the constant fear-stress of systemic failures facing all of us these days.  For the poor here, there are not enough jobs and not enough money to meet basic needs.  Remove that stress, because people are heavily self-medicating with bad drugs and bad food.  Remove that need.  Now.  Also, legalize marijuana completely.  Let people grow pot in their garden if they want, again to remove the DEFENSIVE nature of it now and promote OPENNESS instead.  Remove the chronic fear-stress of hiding everything all of the time.

garden path front yard 2020 June 23Basic survival needs:
Make food, clothing, shelter, and healthcare easily available.  Other countries do it, and the USA is supposedly better than them, so what's the issue here?  I eliminated grass from my front yard and planted strawberries, raspberries, and juneberries.  Everyone is welcome to pick them.  I'm even putting in a path to make it easier for visitors to pick food here (picture at left).  Someone at the end of the block has a "Sharing Is Caring" plastic tub filled with durable food products, free for the taking.  More edible landscaping in the city, please!  More free food lines!  There should be a fixed location in every neighborhood, every day, where someone can get a free meal.  It shouldn't matter if they're too poor to afford food or too mentally broken to prepare their own food.  Once-a-month church events are woefully insufficient.  No adult who is sleep-deprived, nutrition-deprived, and chronically stressed is going to perform well in daily planning, job interviews, or job performance.  Relieve those precursor problems.

Gunfire:
A lot of gunfire here is simple anger/aggression not related to drug business.  Why are so many people (usually male) resorting to violence to relieve their emotions?  I'm not a good person to address this problem.  I'm too self-absorbed to worry what other people think.  My answer to distress is always self-isolation.  I understand that most other people are "built" as social animals and need to develop their skills of non-fatal problem resolution.  I dunno.  More hippie drum circles and Buddhist meditation chants?  LOL  I want those things, yes, but we need to help people other than just me.  Or, taking the opposite tactic, more official training in violent arts?  Would formal training in boxing, karate, and gunfire remove the novelty factor of violence and instill a responsibility ethic instead?

Education:
SHOW kids how they can affect their own future paths in life.  The high school a few blocks from my house has a 13% graduation rate after 4 years, and a 40% graduation rate after 5 years.  Without kids of my own, I'm ignorant about the failure here.  Is someone not encouraging them to build things (woodcraft, gardening, painting, programming, cooking, writing)?  Is someone not encouraging their curiosity (reading, science, history, architecture)?  Are they sleep-deprived (frequent shouting at home or neighborhood gunfire)?  Are they hungry?  Create more local events in every neighborhood that provide food (free/cheap) and peaceful socializing.  If I try to imagine myself failing as these kids are, I can think only of the futility of existence, a lack of personal motivation for effort that's never rewarded.  SHOW them that they matter.  Their hobbies matter.  Their attention matters.  Their voting matters.

Healthcare:
Tax and spend appropriately.  Defund the police to spend for training and job positions that will actually help here.  People here need crisis counseling, family counseling, all kinds of mental health care, normal physician care, environmental justice, and more.  Stop procastinating, government; make it happen.

What will not help: putting National Guard troops at checkpoints on every street corner.  My gut wants that immediate solution, but my brain knows that it's not really a solution.  It's just a suppression of symptoms, not a cure for the underlying disease that needs healing.

Please...  if you have additional suggestions, please create a free Dreamwidth account to add your ideas here.  It matters.  I want things to change.  Everyone here in Jordan in Minneapolis DESERVES for things to change.  It stresses me out to live here, when I already have the adult mental skills to comprehend the complexity involved.  I can't imagine what parents teach their kids about living here, amidst the crime and violence and gunfire.

one of those nights

I'm sure I mentioned that I'm tired of being tired.   I crawled into bed by 7pm tonight and fell asleep.

Unfortunately, the young cat had found styrofoam peanuts in the house during the day and brought at least one into the bedroom.  The older cat found it at 10:05pm and started chasing it all over the bed and me, waking me up.  I watched some tv and went back to bed.  Now, twitches are keeping me awake.  Mostly it's a hyperactive muscle fiber high on my right buttock, but there's also the occasional twitch in my left hamstring and right tricep.

Better days, 2014.  These are supposed to be better days.

I don't wear tech.  I don't wear jewelry.  I don't particularly like even wearing clothes. But here's an idea for technology that I would definitely wear.  The good news is that much of it is already here.  We just need to mix them together and add a small dash of future-tech.

Here are the parts that already exist in our world.  We have smart watches and google Glass, wide screen display for the forearm, the Coin multicard, and the Angel sensor bracelet.

iWatch and googleGlass smartphone in prosthetic arm
coin card Angel sensor bracelet

Here's how to mix them together.  Instead of a prosthetic forearm, make a "gauntlet" that straps a credit-card-sized device to the arm.  The credit card comes with a metallic rim that clicks into place onto the base unit's magnets, so it is easy to return to its home location.

While the card is removed from its gauntlet, it becomes an emulator for any and all credit cards or other identification (keep your library card, your driver's license, your pet food discount card, etc.) all in one device.  The front face of the card is entirely a screen display, so it can appear as any card.

While the device is attached to the gauntlet, it becomes your watch, your calendar, your RSS newsfeed ticker.  It also tracks your heart rate, oxygen level, temperature, and galvanic stress.  The whole credit card face is a display, so you have more space available than just a smart watch.

Remember that metallic rim on the device?  The google Glass easily spots it and reacts to what is displayed on the interface within the rim's border.  The newsfeed says you received a new email?  If Glass says your eyeball is focused on that news item, then Glass pops up a display showing the full text of the email.  If you are looking at the clock icon, then Glass displays your calendar.

I want it.  I would wear it.  I want my Gauntlet-and-Glass combo.  For now, I'm settling for an Angel and a Coin.  I already contributed to their crowdfunding campaigns while they were active.  I look forward to receiving these new tech items in the coming months.  Google, your job is to work on that eye-scanning technology and integrate with an all-in-one gauntlet.  I'm waiting.
