Premature optimization is the root of all evil.
--Donald Knuth
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
Twenty hours at the keyboard can save you two hours of planning.
--Isaac Traxler
Think twice, code once.
--Waseem Latif
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 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
Know the rules well, so you can break them effectively
--Dalai Lama XIV
Walking on water and developing software from a specification are easy if both are frozen.
--Edward V. Berard
People who are really serious about software should make their own hardware
--Alan Kay
Object-oriented programming offers a sustainable way to write spaghetti code. It lets you accrete programs as a series of patches.
--Paul Graham
There ain't no rules around here. We are trying to accomplish something.
--Thomas Edison
College is a waystation - the last convenience store on the road to life-long responsibility.
--Dennis Miller
Good programmers write code that humans can understand.
--Martin Fowler
Progress is possible only if we train ourselves to think about programs without thinking of them as pieces of executable code.
--Edsger W. Dijkstra
'Martyrdom' is the only way a person can become famous without ability.
--George Bernard Shaw
Perl – The only language that looks the same before and after RSA encryption.
--Keith Bostic
It's got to be the going not the getting there that's good.
--Hary Chapin
Not only is this incomprehensible, but the ink is ugly and the paper is from the wrong kind of tree.
--Professor W.
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
Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live
--John Woods
There is nothing good or bad about knowledge itself; morality lies in the application of knowledge.
--Jon Erickson
A change in perspective is worth 80 IQ points
--Alan Kay
With software there are only two possibilites: either the users control the programme or the programme controls the users. If the programme controls the users, and the developer controls the programme, then the programme is an instrument of unjust power.
--Richard Stallman
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
A language that doesn't affect the way you think about programming is not worth knowing.
--Alan Perlis
