See? 1950's technology isn't so bad. 😉
This is good to know! The last time I had to do Easter calculations, I use a traditional algorithm based on the Catholic version of the holiday. Then someone showed me the Orthodox version (Julian calendar) so we had to run them together. Decades ago, two of the guys on my programming team were Russian or Greek Orthodox (I don't remember now) and they got a lookup table from their priest. The first time we needed it, it worked okay because the two Easters happen to coincide with our test case. Mercifully, I'd switched employers when the first problem occurred.
And I love 1950s technology! I still balance my checkbook with an abacus (Chinese style, with Japanese style beads). When I cannot use a slide ruler anymore – maybe just the C and D scales for multiplication. I actually thought about proposing a book that would used McBee cards for teaching database in elementary and middle school. I will need to find an agent for this. And I still wear cuff links and a pocket protector 🙂
Heh... too funny. I actually wrote a sort algorithm based on the old IBM card sorter. It provided incredible stability between multiple sorts and blew the doors off the Shell Sort method a colleague of mine wrote. And, if you're still using a classic slip-stick, you're way behind. You need to upgrade to a circular slide rule. 😉
