- A man with one watch is certain about time. A man with two watches isn't.
- The more knowledge you gained, the less certain you are of it.
- If you think you understand science (or computers or women), you're clearly not an expert
- Technicians are the only ones that don't trust technology
- All impossible failures, will happen at the test site.
Corollary: All impossible failures will happen on the clients desktop - The more you want to contact someone over an instant messenger is inversely proportional to the chances that they will be on-line.
- The more important your email is, the worse your email client will screw it up.
- The degree to which a device will function is directly proportional to the number of times it has been bashed and inversely to its cost.
- A device having an indestructible component or is user serviceable is deemed unsafe until it's replaced by an expensive, unobtainable, inefficient component which needs constant servicing.
- A failed 25¢ part cannot be replaced by a new 25¢ part, but by a sub-assembly whose cost is equal to or greater than that of the device in need of the part
- The cost and availability of a replacement part are in inverse proportion to the cost of the whole system: a $1500 device will fail because of the burnout of a 25¢ capacitor. But the 25¢ capacitor is either
- no longer manufactured
- manufactured only by a company in Outer Mongolia with an 18-month backlog
- available only as part of a $1450 sub-assembly
