Proforma I made for arrogant normies...
If I'm correct, your entire world view is wrong and your decision to not do what I'm doing will be utterly devastating for you.
Instead of putting in the many hours required to know what I know, you're the one living in hope, hope that I'm an a fool or unwise.
It's a common behaviour of all the normies out there, all doomed to be the last in to Bitcoin, missing out tremendously. I can't imagine how painful it will be.
To have some idea, look at Peter Schiff, he talks about how bad Bitcoin is more than he talks about gold! That's raw PAIN.
Bitcoin Derangement Syndrome is a life of anguish. I hope I can snap you out of your belief system, it's uncomfortable to do, but the future distress coming is worse.
AIl you have to do is study it for several hours with an open mind, instead of hoping for its death.
New insights for teaching kids Trigonometry, might help some homeschooling champion parents...
Sin, Cos, and Tan is unnecessarily taught all together, causing confusion, and difficulty memorising.
It's made worse by teaching fractions of triangle sides, "Sine is opposite over hypotenuse", and then mnemonics are taught..SOH CAH TOA.
Ridiculous.
I had to undo a lot of this crap today teaching my daughter, and the new system was easier and she got it straight away...
To begin with, forget Tan. And forget side ratios initially.
1. For any right angle triangle, the two other angles, theta and alpha, add up to 90 deg.
2. Any two right-angle (RA) triangles with the same two other angles are similar triangles. If the hypotenuse is also the same SIZE, then they are identical triangles. (Explain this by discussing zooming in and out, triangle gets bigger and smaller, but it looks like the same triangle. And so these numbers define the "shape of shapes", but not always how big or zoomed in they are).
3. Always work with triangles where the hypotenuse is 1, to begin with. To eliminate complexity of absolute sizes, start with the "shape of the shapes".
4. Sine is the main one to know, and learn to "feel" that it's the most important - it helps memory. It refers to the size of the triangle-side furtherest from an angle (don't call it a ratio yet).
Animate the angle changing, and the side's size changing with it (and triangle shape). And of course it always remains a RA triangle.
On one extreme where the angle is approaching zero the triangle becomes acute, then almost just a straight line. The hypotenuse is to be considered like a clock hand, fixed in size of 1. As the angle is approaching zero, the sine-side (opposite) is approaching 0 in length, and the other side, the cos side (adjacent), is approaching the same length as the hypotenuse, 1. Show how both sides HAVE to change size, because you're not changing the size of the hypotenuse.
On the other extreme, when the angle is opening up towards 90°, the sine side is approaching 1 in length, and the cos (adjacent) side is approaching 0. Another straight line.
When the angle is 45 deg, the animation is exactly half way between the two extremes and both angles (theta and alpha) must equal 45 degrees (otherwise it's not a right angle triangle). And the 2 changing sides are equal in length.
Demonstrating this, I think, is much more important than memorising opposite over hypotenuse, adjacent over hypotenuse, and opposite over adjacent.
Then when you have a something like, sin(37 degrees), one can appreciate this DEFINES a triangle's shape.
Then, once they get that, you can explain the vale of sine(T) is actually a COMPARISON to the hypotenuse, which has always been 1 so far, and also is always the longest side of the RA triangle (so the value of a side has always been under one). Comparison means a ratio.
0.5 means half the size compared to the hypotenuse.
THEN, show...
sine (45) = A/H = 0.7
... as an example, and demonstrates how with bigger triangles (hypotenuse greater than 1), if the shape of the triangle is the same, defined by angle, then sin(T) stays the same, and always under 1, no matter the larger hypotenuse.
Once comfortable, draw sine waves and cos waves (careful not to become the whiteboard meme guy here).
Then when comfortable with that, show a clock and the triangles formed in the 4 quadrants.
Introduce radians.
Only THEN talk about Tan, opposite over hypotenuse, or sineT/cosT.
Just my 2 π
Listen up and read to the end if you have no friends, particular no Bitcoiner friends...
Today I added a cool feature to ParmaDrive.
When you pair your ParmaDrive home server to another ParmaDrive (A ParmaTwin), each machine can backup data to the other over an encrypted secure "tunnel".
That's not new.
The new part is the ability to write messages to a desktop text file to each other, eg, "Oi, dickhead, I was doing a backup yesterday and your machine was down, what's the deal?"
Obviously there are safety measures so the file can't be executed, just read.
If you don't have a friend who can be your ParmaTwin, you can just allow me to pair you up with another waiting client. You don't need to trust each other, you just need to trust that you're both interested in keeping your machines on, so that you can back up data to each other.
It's probably a good idea to video meet and get acquainted anyway. You don't need to reveal personal info necessarily, but you might become friends, who knows.
Generally, all ParmaDrive/ParmanodL clients are Bitcoiners who tend to have the same core values.
Self sovereign data is as risky as self custody Bitcoin -- doesn't mean you do the normie thing and give up! "Yeah, but what are you gonna do?"
Getting free from Google and Apple for your data storage is a massive and difficult job - as designed.
Even the phone, it's hard to use a Google/Apple free device if you have your data with them.
You can't extract yourself all at once... there is a lot to do, but you can chip away and eventually all the pieces come together. Doing something is better than nothing, then doing something more is better than stopping there.
To help, I have ParmaDrive - this is a machine that, besides being a Bitcoin node, is designed to help you store your own data safely.
STEP ONE is to put a copy of your data on the 16TB drive, and practice accessing it in preference to "the cloud".
STEP TWO is to have a copy on anothet drive in your home
STEP THREE is to have a copy offsite (more on that below)
STEP FOUR is to delete your data from cloud services now that you have copies and geographical refund.
REMOTE BACKUPS - OPTION 1
You can buy a second external hard drive, manually sync it with your first drive and then take it offsite. Periodically you have to take a risk by bringing it back to the original site, syncing, then taking it back offsite.
OPTION 2
You can have a second ParmaDrive kept offsite, which maintains a permanent private connection that I will configure. Each night, any changes to the data is backed up automatically. It's kind of like Apple time machine snapshots. You can browse the snapshot and download any files that you might have lost.
OPTION 3
Same as option 2 but a friend, ParmaTwim, has the second machine, and you reserve drive space to reciprocate encrypted backups. You don't need to trust each other because neither can see the others' data as it's encrypted.
OPTION 4
You can do option 3 but with another customer as a ParmaTwin. Again you don't need to trust them but it is nice to make contact and get to know each other. Just ask to be on a list when you order a machine.
OPTION 5
You can ParmaTwin with more than one person if it helps you feel more secure. You can also offer to be a ParmaTwin for more than one person and you can even ask for a fee - be your own mini data centre.
OPTION 6
You can sync to ParmaData, a datacentre I haven't yet made available. Later.
That's all I got for self sovereign data tips today.
