Jewish [Math] Problems

This is a special collection of problems that were given to select applicants during oral entrance exams to the math department of Moscow State University. These problems were designed to prevent Jews and other undesirables from getting a passing grade. Among problems that were used by the department to blackball unwanted candidate students, these problems are distinguished by having a simple solution that is difficult to find. Using problems with a simple solution protected the administration from extra complaints and appeals. This collection therefore has mathematical as well as historical value.

The Man Who Inspired Jobs

“Market research is what you do when your product isn’t any good.”

Thank you, Steve

My first home computer was an Apple IIe, in 1984. I had already started learning to program (on a TRS-80 Model III), but that IIe was where I really got excited about computers and programming. I wrote utilities and games in BASIC, then 6502 assembly language (I would write the assembler instructions down on paper, then translate those by hand to the byte code), hacked games (Bard’s Tale character editor, anyone?), and even taught programming classes to other kids.

The Steves, Jobs and Wozniak, were always heroes of mine, although it wasn’t until I was older that I truly appreciated Jobs’ brilliance. I always thought that Woz, the engineer, was the one who made the magic happen, but if it weren’t for Jobs, Apple could well have faded with Beagle Bros into obscurity.

Like a majority of people I know, I use Apple products daily, for work, entertainment, and communication. I can’t think of another company that puts as much thought into the quality of their products, both in terms of construction and user experience, and there’s no doubt that Steve Jobs is the one to thank for that.

I still have that IIe, in a suitcase in my garage. I think I’ll boot it up tonight in tribute. Thanks for everything, Steve. Rest in peace.

Update:

IIe Thanks
