Everyday life is like programming, I guess. If you love something you can put beauty into it.
--Donald Knuth
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
Object-oriented programming offers a sustainable way to write spaghetti code. It lets you accrete programs as a series of patches.
--Paul Graham
Premature optimization is the root of all evil.
--Donald Knuth
That's the thing about people who think they hate computers. What they really hate is lousy programmers.
--Larry Niven
...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
First solve the problem. Then, write the code.
--Waseem Latif
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
The big optimizations come from refining the high-level design, not the individual routines.
--Steve McConnell
[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
A university is what a college becomes when the faculty loses interest in students.
--John Ciardi
The most difficult thing in the world is to know how to do a thing and to watch someone else do it wrong without comment.
--Theodore H. White
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
What is a university/college when the students lose interest?
--Isaac Traxler
People who are really serious about software should make their own hardware
--Alan Kay
Perl – The only language that looks the same before and after RSA encryption.
--Keith Bostic
How do you expect to succeed if you do not know the rules?
--Anonymous
Without requirements and design, programming is the art of adding bugs to an empty text file.
--Louis Srygley
I'm not a great programmer; I'm just a good programmer with great habits.
--Kent Beck
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
