Devices on amazon are repurposed tENS devices which control voltage rather than current. tVNS is an emerging area of research and to repeat studies you need to understand the "dosage" which means the current delivered, because the same voltage can result in different currents depending on resistance.
The accuracy of the biphasic waveform is also a factor.
With another day and a half of the Bank Holiday to fill you might want to compare performance of Wordpress with Openlitespeed. Theres an ec2 image that makes it easy. My site saw a 5x speed up which has made me an advocate.
Confirms they are not salting passwords and probably storing them in plain text. I think the app doesnt allow special charactors in passwords either.
They really should be called out over this "security".
I hate wasting time on sites like ebay, but inevitably get sucked into them every now and then. I'd gladly pay you ten bucks a month to surface stuff I might want, even if I had to do some initial setup work.
For example if you see an X61 with the SXGA+ screen on a buy now price, I want to know (rare as rocking horse poo). Or Lego with at least 30% off is always good for my boy or birthday presents.
You'd need to err on the side of caution, because I'd rather miss stuff than be spammed, but thankfully that makes your job easier!
Some sort of feedback loop might be useful. I don't profess to understand the 12 steps (and not to trivialise by comparison) but I guess counting the number of successful days of not doing something in a chain becomes reinforcing e.g. when has a smoker actually stopped smoking?
Or alternatively is the payoff a reward e.g. "Dont eat a donut for 6 days if then eat a donut else try again"
