How do you expect to succeed if you do not know the rules?
--Anonymous
Know the rules well, so you can break them effectively
--Dalai Lama XIV
The three principal virtues of a programmer are Laziness, Impatience, and Hubris. See the Camel Book for why.
--perldoc perl
Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live
--John Woods
People who are really serious about software should make their own hardware
--Alan Kay
...I’m not saying simple code takes less time to write. You’d think it would since you end up with less total code, but a good solution isn’t an accretion of code, it’s a distillation of it.
--Robert Nystrom
The big optimizations come from refining the high-level design, not the individual routines.
--Steve McConnell
Programming is the art of thinking really hard about how to avoid having to think really hard.
--unknown
Progress is possible only if we train ourselves to think about programs without thinking of them as pieces of executable code.
--Edsger W. Dijkstra
Managers of programming projects aren’t always aware that certain programming issues are matters of religion. If you’re a manager and you try to require compliance with certain programming practices, you’re inviting your programmers’ ire. Here’s a list of religious issues:
■ Programming language
■ Indentation style
■ Placing of braces
■ Choice of IDE
■ Commenting style
■ Efficiency vs. readability tradeoffs
■ Choice of methodology—for example, Scrum vs. Extreme Programming vs. evolutionary delivery ■ Programming utilities
■ Naming conventions
■ Use of gotos
■ Use of global variables
■ Measurements, especially productivity measures such as lines of code per day
--Steve McConnell
When in doubt, do something.
--Harry Chapin
When they first built the University of California at Irvine they just put the buildings in. They did not put any sidewalks, they just planted grass. The next year, they came back and put the sidewalks where the trails were in the grass. Perl is just that kind of language. It is not designed from first principles. Perl is those sidewalks in the grass.
--Larry Wall
The issue of finding the best possible answer or achieving maximum efficiency usually arises in industry only after serious performance or legal troubles.
--Steven S. Skiena
The really good programmers spend a lot of time programming. I haven’t seen very good programmers who don’t spend a lot of time programming. If I don’t program for two or three days, I need to do it. And you get better at it—you get quicker at it. The side effect of writing all this other stuff is that when you get to doing ordinary problems, you can do them very quickly.
--Joe Armstrong
The real nightmare, worse than the one in which the Big Machine wants to kill you, is the one in which it sees you as irrelevant, or not even as a discrete thing to know.
--Benjamin H Bratton
A change in perspective is worth 80 IQ points
--Alan Kay
Everyday life is like programming, I guess. If you love something you can put beauty into it.
--Donald Knuth
Any fool can write code that a computer can understand. Good programmers write code that humans can understand.
--Nartin Fowler
Perl – The only language that looks the same before and after RSA encryption.
--Keith Bostic
Programming isn't about what you know; it's about what you can figure out.
--Chris Pine
The personal computer isn't "personal" because it's small and portable and yours to own. It's "personal" because you pour yourself into it - your thoughts, your programming.
--Audrey Watters
It's got to be the going not the getting there that's good.
--Hary Chapin
Learn the rules like a pro, so you can break them like an artist
--Pablo Picasso
If the steps become to big, they become walls...
--Herb Sutter
So if an algorithm is an idealized recipe, a program is the detailed set of instructions for a cooking robot preparing a month of meals for an army while under enemy attack
--Kernighan Brian
Delivering good software today is often better than perfect software tomorrow, so finish things and ship.
--David Thomas
