Delivering good software today is often better than perfect software tomorrow, so finish things and ship.
--David Thomas
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
Simple things should be simple, complex things should be possible.
--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
Without requirements and design, programming is the art of adding bugs to an empty text file.
--Louis Srygley
If the steps become to big, they become walls...
--Herb Sutter
I'm not a great programmer; I'm just a good programmer with great habits.
--Kent Beck
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
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
Walking on water and developing software from a specification are easy if both are frozen.
--Edward V. Berard
[On identifying talented programmers] It’s just enthusiasm. You ask them what’s the most interesting program they worked on. And then you get them to describe it and its algorithms and what’s going on. If they can’t withstand my questioning on their program, then they’re not good. I’m asking them to describe something they’ve done that they’ve spent blood on. I’ve never met anybody who really did spend blood on something who wasn’t eager to describe what they’ve done and how they did it and why. I let them pick the subject. I don’t pick the subject, so I’m the amateur and they’re the professional in this subject. If they can’t stand an amateur asking them questions about their profession, then they don’t belong.
--Ken Thompson
Not only is this incomprehensible, but the ink is ugly and the paper is from the wrong kind of tree.
--Professor W.
Along every step of our journey through life, our mind is being programmed. If we are not programming it ourselves, someone else is doing it to us.
--Joseph Rain
Good programmers write code that humans can understand.
--Martin Fowler
It's got to be the going not the getting there that's good.
--Hary Chapin
Know the rules well, so you can break them effectively
--Dalai Lama XIV
There ain't no rules around here. We are trying to accomplish something.
--Thomas Edison
But while you can always write 'spaghetti code' in a procedural language, object-oriented languages used poorly can add meatballs to your spaghetti.
--Andrew Hunt
How do you expect to succeed if you do not know the rules?
--Anonymous
College is a waystation - the last convenience store on the road to life-long responsibility.
--Dennis Miller
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
Einstein repeatedly argued that there must be simplified explanations of nature, because God is not capricious or arbitrary. No such faith comforts the software engineer.
--Frederick P. Brooks Jr.
When in doubt, do something.
--Harry Chapin
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
Some of the best programming is done on paper, really. Putting it into the computer is just a minor detail.
--Max Kanat-Alexander
Any fool can write code that a computer can understand. Good programmers write code that humans can understand.
--Martin Fowler
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
Twenty hours at the keyboard can save you two hours of planning.
--Isaac Traxler
The three principal virtues of a programmer are Laziness, Impatience, and Hubris. See the Camel Book for why.
--perldoc perl
Any fool can write code that a computer can understand. Good programmers write code that humans can understand.
--Nartin Fowler
How do you expect to succeed if you do not know the rules?
--Anonymous
First solve the problem. Then, write the code.
--Waseem Latif
Object-oriented programming offers a sustainable way to write spaghetti code. It lets you accrete programs as a series of patches.
--Paul Graham
Progress is possible only if we train ourselves to think about programs without thinking of them as pieces of executable code.
--Edsger W. Dijkstra
