P2P tools for developing decetralized services:
Blockstack is a new decentralized internet where users own their data and apps run locally. A browser portal is all that’s needed to get started.
A peer-to-peer hypermedia protocol
to make the web faster, safer, and more open.
An open network for secure, decentralized communication.

UPDATE2: Yay! :-) someone did it and we both got 50$ :-)
UPDATE: absolutely no one took advantage of this. I don't know why. Me and some friend of my daughter got 50 bucks each out of it, just for opening an account and depositing 100$ (which I then spent, of course). I think it's still going until (update 2) August 30th 2017, but I'm putting a readmore in to make this post smaller now.
So my daughter said a friend of hers could use the money and if I opened a bank account using her code I'd make each of us $25.
Sure. Whatever... Moving on...
But this one is actually 'A Thing'. Tangerine Bank is actually paying people to open bank accounts. And, by the time I realized that I needed to deposit $100 first, they'd changed the rules and I got $50 instead of the expected $25 (see image below).
It's the Bank of Nova Scotia's online plan to get rid of brick and mortar (and tellers and CSR's and...) expenses.They bought IDG and renamed it to Tangerine Bank, so you can use all their orange 'Tangerine' debit cards in any Bank of Nova Scotia bank machine for free.
Tangerine charges no fees for most things you want to do with banking online (for now...) and it will pay you to open an account. And it will pay for referrals. Yes, you are correct, this sounds just like multi-level marketing and ponzi schemes, but I'm still eating a salad made with feta and olive oil that I paid for with Tangerine's money as I type this.
Just find a friend and sign up with them. or use my Orange Key which is 46420773S1.
As it happens, I found myself in need of a Roman Catholic liturgical calendar. That calendar is 'fun' (for very low values of 'fun'), because it needs to be calculated from both the lunar and solar year.
The principle date for Catholics is Easter, which is defined as the Sunday following the full moon that follows the northern spring equinox (the paschal full moon). The differences between the Julian calendar and the modern Gregorian calendar make it really 'fun' historically. Check out the details here.
Luckily for us, RomCal.net exists and he's done all the hard work for us already. The C source is straight-forward and compiles easily. We just need to change one file: 'fixed.h'. :-)
O.K., so here is my Canadian Saints version for various years in ical (ics) format: romcal2017.ics
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.
