What is Sandstorm?
It's a way for you to have your own 'Facebook', 'Reddit' and much else. Your very own. No faceless corporation involved mining your personal information to sell to advertisers (that's how gmail and facebook make money, after all).
Sandstorm is completely and privately YOURS and no one elses.
And it is very easy to install on your own server (regular Linux box on your LAN), even easier to have someone else do it and rent the space ( http://sandstorm.io ), and moderately simple to own your own instance that you can share publically. This little tutorial will show you how to have your own sandstorm:
- download and install Sandstorm on your own box
- configure it so that it is accessible by anyone on the internet
- and it will cost you exactly nothing per month to do it
Mind you, after I have tested Sandstorm on my local box behind a router, I WILL be moving it to a 'real' server (actually, just a vps these days). My power is dodgy and not redundant, I haven't configured it for off-site backups, and it's just a 10-year old box that would otherwise gather dust if I didn't experiment with it. Still, you could arrange for decent rsync or zfs/btrfs backups and get them offsite and buy a battery (UPS). Up to you.
Plus, I think it would be quite nice for a household to have their own private 'cloud' on their own private LAN.
You do need to be a bit geeky to install Sandstorm, but not much. And you need to be running Linux, not Windows.
As you can see below, you need to map some ports if playing at home behind a router. An interesting effect of using Sandstorm's free SSL via DNS is that you can also use other ports at the same address (but not with SSL). For example, I installed a VM of ERPnext and simply used the same personal Sandstorm address, but specified a different port.
A very cool new development: the Sandstorm team has figured out a way to give you free SSL! The road was a bit bumpy for doing it behind a NAT router, but now it works! NB it also takes care of updating your dynamic dns. Awesome!
TL;DR It is very useful in many financial and construction situations, saves heaps of time and you don't even have to actually memorize all twelve numbers. Also, just random day to day arithmetic problems.
First off, I should let you know exactly why. After memorizing less than 12 simple numbers you will instantly be able to calculate, to as many decimal places problems you wish, things like:
How much per month is $500/year? Or $70. Or $8,000 or any other similar amount. Down to the penny. In your head.
The inverse is true too: you'll recognize decimal twelfths when you hear them and immediately know just how much a year that would mean to your budget.
What is the accurate number of square feet given something like 5'-3" X 17'-5" and a calculator (hint: it's how to enter 5 inches and 3 inches properly).
It's just that twelfths happen so often in Western culture that they are worth bothering about. Twelfths pop up here and there randomly too.
Is $8 for a package containing three X 400 gram chubs of hamburger a good deal? This is actually the real-world reason from the other day that made me bother to write this post. 3 X 400 grams = 1200 grams. Twelve Hundred. Twelve. Now it's a question of $8/12 or 67 cents per 100 grams. Simple and instant. Just slop the decimal point around until it makes sense.
This video does a good job of showing some of the area around Terrace, BC, Canada: https://www.youtube.com/watch?v=Sx278hWyg_M At the time of that video, she seems to have been a pharmacy student visiting Terrace to do her practicum. Here are her other videos: https://www.youtube.com/channel/UCGW2LDEk1ug9R5IKMUooybQ
She was very kind and didn't make fun of our small town, even though she is from the big city of Vancouver. Well, Canadians are supposed to be polite after all...
Terrace isn't really very North as real North goes a LOT further up, but we are still often short of health care vocations. The lady talks about her Shoppers being in "THE medical building". Yes, it is the only "medical building" in town and, counting the hospital, we have only 5 pharmacies. However, you don't have to go much further North to be THE only pharmacist or THE only doctor in town.
Terrace has about the same positives as Vancouver: summers aren't too hot, winters aren't too cold, but we still have swimming and skiing seasons. Lots of beautiful scenery and wildlife, but with the added bonus of low housing prices and no traffic congestion. Check out Northern Health for job postings.
