How I Start Companies

My fastest-growing and most profitable business ever was the store the back of Ellen Nottingham's classroom at T.T. Minor Elementary School. I bought a box of pencils at a store near our bus stop, and Cy Keener and I sold them the next day at school for 15 cents each.

The next week, we diversified into erasers, pens, and paper. A month later, after expanding into higher margin, about 3 weeks of reinvestment, and annoying pink things that Cy claimed that girls would buy (he was right). We were netting about $20 per week, which was back when $20 meant something.

The partnership worked pretty well: Cy had a good idea of what peple would buy, and I was stingy with the money.

Initial investment: five dollars.

Serial entrepreneur

Starting a business? Have a new idea? I'd love to hear about it!.

Maybe I can point you to someone who has similar interests. Maybe I can help you define a good business plan that'll save you from losing your shirt.

Good questions to ask yourself are: Is there an easier way to earn a living? Has it already been done before? Is your business idea suited to your risk tolerance? Is running a business compatible with your values?

Check out the business I helped start:

  • Raosoft, Inc.. Profit = Revenue - Expenses. Keep your expenses low.

Innovations

JSDB is a lightweight Linux/Windows JavaScript shell for gluing together databases, XML, web sites, and email. "a superbly powerful and extensible environment for managing batch tasks." If you like Perl, you'll probably like JSDB too.

Raosoft, Inc. makes the best web survey software available. EZSurvey is good and cheap, and InterForm is good and fast. I wrote EZSurvey and maintain EZReport.

Exploit online databases. Machine translation from SpanishItalianPortuguese,  and French.

Driver code for daptive optics. Buy the 128-channel MEMS driver circuit from Alta Via Technologies.

Video Authentication Steganography
A system for traceable photography. Provisional patent application filed by Caltech on Jan 2001, abandoned Jan 2002, placing my rights to the invention in the public domain. A professor at Princeton filed a similar patent in Sep 2000.

Scope interface
Talk to your Tektronix digital scope through a serial port.

SPIT
System Plotting Interactive Tool is a graphical Matlab program for plotting Bode, Nichols, and Nyquist spectra of Simulink models (wihout having to use the command line interface).

SusRes
Calculate suspended interferometer mirror resonance frequencies in Mathematica. This is based on the complete linearized Lagrangian for a single mirror. It is more accurate than the SUSRES Fortran program, but less accurate than Mark Barton's model.

Thermal noise plotter
Calculate thermal noise spectra for LIGO mirrors. Uses the latest (but not necessarily correct) theoretical models.

Mode matching calculator
Propagate Gaussian beams through lenses, cavities, and optics in an Excel spreadsheet.

Research

Current project: Direct imaging of extrasolar planets.

Thesis: Mirror Thermal Noise in Interferometric Gravitational-Wave Detectors. Selected portions: Thermal noise encyclopedia, cross-polarized interferometer experiments, Interferometers, circuits, polarization noise, and lab checklists.

Gravitational lensing by binary black holes
Qualitative visualization of gravitational lensing of starlight by nearby black holes. Gravitational redshift and retardation are not included in the model. Windows.
