Troutman's Laws of Computer Programming:
1. Any running program is obsolete.
2. Any planned program costs more and takes longer.
3. Any useful program will have to be changed.
4. Any useless program will have to be documented.

7. The complexity of a program grows until it exceeds the capability of the maintainers.
8. Information necessitating a change in design is always conveyed to the implementers after the code is written. Corollary: Given a simple choice between one obviously right way and one obviously wrong way, it is often wiser to choose the wrong way, so as to expedite subsequent revision.
9. The more innocuous a modification appears, the more code it will require rewriting.
10. If a test installation functions perfectly, all subsequent systems will malfunction.

Troutman's Programming Postulates:
1. If a test installation functions perfectly, all subsequent systems will malfunction.

3. Job control cards that positively cannot be arranged in improper order will be.
4. Interchangeable tapes won't.
5. If the input editor has been designed to reject all bad input, an ingenious idiot will discover a method to get bad data past it.
6. Profanity is the one language all programmers know best.

Laws of computer-dom according to Golub:
1. Fuzzy project objectives are used to avoid the embarrassment of estimating the corresponding costs.
2. A carelessly planned project takes three times longer to complete than expected; a carefully planned project takes only twice as long.
3. The effort required to correct course increases geometrically with time.
4. Project teams detest weekly progress reporting because it so vividly manifests their lack of progress.
Lubarsky's Law of Cybernetic Entomology:
There's always one more bug.
Build a system that even a fool can use, and only a fool will want to use it.
Nothing is impossible for the man who doesn't have to do it himself.
If it looks easy, its tough. If it looks tough, its damn near impossible.
The probability of anything happening is in inverse ratio to its desirability.
Variables won't; constants aren't.
In any computer system, the machine will always misinterpret, misconstrue, misprint, or not evaluate any math or subroutines or fail to print any output on at least the first run through.
Corollary to Pierce's Law:
When a compiler accepts a program without error on the first run, the program will not yield the desired output.
Harvard's Law as applied to computers:
Under the most rigorously controlled conditions of pressure, temperature, volume, humidity, and other variables, the computer will do as it damn well pleases.

Any inanimate object, regardless of its position, configuration, or purpose, may be expected to perform at any time in a totally unexpected manner for reasons that are either entirely obscure or else completely mysterious.
Horner's Five Thumb Postulate:
Experience varies directly with equipment ruined.
Nothing ever gets built on schedule or within budget.
Rule of Accuracy:
When working toward the solution of a problem, it always helps if you know the answer.
Computing power increases as the square of the cost.
To estimate the time it takes to do a task; estimate the time you think it should take, multiply by two and change the unit of measure to the next highest unit. Thus, we allocate two days for a one hour task.
Gilb's Laws of Unreliability:
1. Computers are unreliable, but humans are even more unreliable.
2. Any system which depends on human reliability is unreliable.
3. Undetectable errors are infinite in variety, in contrast to detectable errors, which by definition are limited.
4. Investment in reliability will increase until it exceeds the probable cost of errors, or until someone insists on getting some useful work done.
Lets not forget Hendrickson's Law (but still computer related):
If a problem causes many meetings, the meetings eventually become more important than the problem.
Gray's Law of Programming:
'n + 1' trivial tasks are expected to be accomplished in the same time as 'n' trivial tasks.
Logg's Rebuttal to Gray's Law:
'n + 1' trivial tasks take twice as long as 'n' trivial tasks.
Ninety-Ninety Rule of Project Schedules:
The first 90% of the task takes 10% of the time, and the last 10% takes the other 90% of the time.
Weinberg's Second Law:
If builders built buildings the way programmers wrote programs, then the first woodpecker that came along would destroy civilization.
Third time debugging is only the beginning...not a charm.
Thinly sliced cabbage.
The difference between hardware and software:
"Those parts of the system that you can hit with a hammer are called hardware; those program instructions that you can only curse at are called software."
