Interesting programming laws.  

Bove's Theorem
The remaining work to finish in order to reach your goal increases as
the deadline approaches.

Brook's Law
Adding manpower to a late software project makes it later.

Cann's Axiom
When all else fails, read the instructions.

Deadline-Dan's Demon
Every task takes twice as long as you think it will take. If you
double the time you think it will take, it will actually take four
times as long.

Demian's Observation
There is always one item on the screen menu that is mislabeled and
should read "ABANDON HOPE ALL YE WHO ENTER HERE."

Dr. Caligari's Come-Back
A bad sector disk error occurs only after you've done several hours
of work without performing a backup.

Finagle's Rules:

To study an application best, understand it thoroughly before you
start.
Always keep a record of data. It indicates you've been working.
Always draw your curves, then plot the reading.
In case of doubt, make it sound convincing.
Program results should always be reproducible. They should all
fail in the same way.
Do not believe in miracles. Rely on them.
Franklin's Rule
Blessed is the end user who expects nothing, for he/she will not be
disappointed.

Gilb's Law of Unreliability

At the source of every error which is blamed on the computer you
will find at least two human errors, including the error of blaming
it on the computer.
Any system which depends on human reliability is unreliable.
Undetectable errors are infinite in variety, in contrast to
detectable errors, which by definition are limited.
Investment in reliability will increase until it exceeds the
probable cost of errors, or until someone insists on getting
some useful work done.
Gummidge's Law
The amount of expertise varies in inverse proportion to the number
of statements understood by the general public.

Harp's Corollary to Estridge's Law
Your "IBM PC-compatible" computer grows more incompatible with every
passing moment.

Heller's Law
The first myth of management is that it exists.

Hind's Law of Computer Programming

Any given program, when running, is obsolete.
If a program is useful, it will have to be changed.
If a program is useless, it will have to be documented.
Any given program will expand to fill all available memory.
The value of a program is proportional to the weight of its
output.
Program complexity grows until it exceeds the capability of the
programmer who must maintain it.
Make it possible for programmers to write programs in English,
and you will find that programmers cannot write in English.
Hoare's Law of Large Programs
Inside every large program is a small program struggling to get out.

The Last One's Law of Program Generators
A program generator creates programs that are more "buggy" than the
program generator.

Meskimen's Law
There's never time to do it right, but always time to do it over.

Murphy's Fourth Law
If there is a possibility of several things going wrong, the one
that will cause the most damage will be the one to go wrong.

Murphy's Law of Thermodynamics.
Things get worse under pressure.

Ninety-Ninety Rule of Project Schedule
The first ninety percent of the task takes ninety percent of the
time, and the last ten percent takes the other ninety percent.

Nixon's Theorem
The man who can smile when things go wrong has thought of someone
he can blame it on.

Nolan's Placebo
An ounce of image is worth a pound of performance.

Osborn's Law
Variables won't constants aren't.

O'Toole's Commentary on Murphy's Law
Murphy was an optimist.

Peer's Law
The solution to a problem changes the problem.

Rhode's Corollary to Hoare's Law
Inside every complex and unworkable program is a useful routine
struggling to to be free.

Robert E. Lee's Truce
Judgement comes from experience; experience comes from poor judgement.

Sattinger's Law
It works better if you plug it in.

Shaw's Principle
Build a system that even a fool can use, and only a fool will want to
use it.

Snafu Equations

Given any problem containing N equations, there will be N+1
unknown.
An object or bit of information most needed will be least
available.
Any device requiring service or adjustment will be least
accessable.
Interchangeable device's won't.
In any human endeavor, once you have exhausted all possibilities
and fail, there will be one solution, simple and obvious, highly visible
to everyone else.
Badness comes in waves.
Thoreau's Theories of Adaptation

After months of training and you finally understand all of a
program's commands, a revised version of the program arrives
with an all-new command structure.
After designing a useful routine that gets around a familiar "bug"
in the system, the system is revised, the "bug" is taken away, and
you're left with a useless routine.
Efforts in improving a program's "user friendliness" invariably
lead to work in improving user's "computer literacy."
That's not a "bug," that's a feature!
Weinberg's Corollary
An expert is a person who avoids the small errors while sweeping on
to the grand fallacy.

Wood's Axiom
As soon as a still-to-be-finished computer task becomes a life-or-death
situation, the power fails.

Zymurgy's First Law of Evolving System Dynamics
Once you open a can of worms, the only way to recan them is to use
a larger can.


1.墨非定律：如果坏事有可能发生，不管这种可能性多幺小，它总会发生，并引起最大可能的损失。

There is a name for this phenomenon: Murphy’s Law. It was named after Captain Edward Murphy, a U.S. Air Force engineer. In 1949, Captain Murphy cursed at one of his men who had made a mistake, and said,“if there is any way to do it wrong, he’ll find it.”

2.二八法则：二八法则主张：以一个小的诱因、投入或努力，通常可以产生大的结果、产出或报酬。就字面意义来看，这发则是说，你所完成的工作里80%的成果，来自于你所付出的20%。
3.马太效应：穷的越穷，富的越富，用时髦的话说就是这是一个赢家通吃的社会。
4.手表定理：有一只表的人知道现在几点了，有两只表的人则无法确定。
5."不值得"定律：不值得做的事，就不值得做好。
6.彼得原理：在一个等级组织中，雇员趋向于晋升到其不称职的地位。
7.零和游戏：游戏者有赢有输，但整个游戏的总成绩永远为零。
8.华盛顿合作规律：一个人敷衍了事﹔两个人互相推诿﹔三个人则永无成事之日。
9.酒与污水定律：如果把一匙酒倒进一桶污水，你得到的是一桶污水﹔如果你把一匙污水倒进一桶酒，你得到的还是一桶污水。
10.水桶定律：一只水桶能装多少水，完全取决与它最短的那块木板。
11.蘑菇管理原则：对于初出茅芦者管理原则如下：将其置于阴暗角落，浇上大粪，任其自生自灭。
12.钱的问题：当某人告诉你："不是钱，而是原则问题"时，十有八九是钱的问题。
13.奥卡姆剃刀：如无必要，勿增实体。简单与复杂定律：把事情变复杂很简单，把事情变简单很复杂。
