Saving condition images

 Dealing with images is a complicated set of circumstances.

First, if I'm going to keep track of all my different condition pictures, it can overwhelm my web hosting server pretty quickly.

Just me, no problem, but, add a few people to the mix and it starts taking significant amounts of room.

To deal with all those images, i needed to pull out my deep thinking cap. So here is the way I'll do it. 

There is a way for me to store information on a user's machine. It's called indexedDB. The problem is this, it has to be extremely secure, so the way an internet browser deals with it, is that it saves information locally but is only accessible from that browser and that website.

Different browser, different data repository. So... how to deal with such diversity, especially considering that the user has multiple machines. The only way I can see them being able to access thir images is to use deep Synchronization techniques.

So, first, if they are on their smartphones, then let them know it is being saved on their smartphone and the images can only be seen from their smartphone. If they use their desktop computer then they need to initiate a Synchronization of their smartphone and their desktop images. That has to be done easily. 

If I see that they have synchronized at any time in the past, I can temporarily store a certain amount of images on my server and automatically synchronize when they open the other machine. It's messy and I have to come up with ways to make it as transparent to the user as possible. That way, if they keep switching machines, like I do, the images will always be available for comparison.

That's a tall order.

Statistics of fasts

I have the graphs working on the extended fasts. All is pretty much good and well to a point. I want to superimpose the condition(s) above the fast times. Bear in mind that what appears complex in this note, the complexity of the program, itself, is at least 30 times more complex. To compare the fasting times to the condition times, for instance, I want to see when I'm losing weight compared to the fasts. Weight is the example here. What is done here will work with the thousands of conditions the members may have. That's a bit complex. The condition check may lie outside of the start and end of the fast.  I can't ignore what is outside the fast, especially if no condition tests were done within the fasts themselves. I have to use the last or average of the weights before the fast. Also, if there is weight checks within the fasts, then I'll use an average of those. When you're travelling through arrays of information, there's all kinds of gotchas that'll caus...

Huge update

 I've been reading several books since last month. The Ketogenic Bible,  Dr Fung's book, David Sinclair's book and more. I absorb these ideas on metabolic systems in the body.  The most interesting is understanding the rebuild/repair system of the body. The main idea I've come to understand is that the human system needs to spend more time on the repair side of metabolism. The thing is, we eat without allowing the body to repair.   The repair of Autophagy in all its types really can't function properly with just a few hours of rest from eating. We are built to repair our cells when we don't eat for a few days. To measure the amount of repair taking place I use the GKI index. For that to work I use the blood tests for Ketones and Glucose using inexpensive blood monitors. Read the levels on my site: mywaterfasts.com.  What I've learned is that it took me three days to reach down to 1.5 on the GKI index so that cysts are being repaired. That fixed my right eye...

Condition Graphs

 The entering and saving of the condition system is working. I am now working on the conditions graph that shows up above the fast graph as a line graph. It's a bit complex. Something like, first cut the conditions that exist before and after the selected dates of the fast graphs, then average the numbers between each fast and create the line point at that height. That gives me the ability to see how my progress corelates to the fasts. So, like, if I'm losing weight, I can see how that particular graph affected my weight or blood pressure or inflammation of my joints etc. After that's done, I'll be working on getting the system, as a whole, to accept multiple people. After that, I'll make the system more efficient. Like being able to login in from the front screen and then jump to the main app screen with some message saying I'm logged in. After that, I want to get the totals of the GKI indexes and maybe graph that. There's still a lot to do but I'm prog...
