For those who didn't make it past the first page, this one's new on me and became an instant favourite:

You can stand on the shoulders of giants OR a big enough pile of dwarfs, works either way.

The best hands down quote in my opinion is:

There are only two hard things in Computer Science: cache invalidation and naming things. -Phil Karlton

I like the variant:

"There are only two hard things in Computer Science: cache invalidation, naming things, and off-by-one errors."

You've confused computer science with programming.

Linux is only free if your time has no value

True, but in my experience it's a worthy investment of valuable time. I spent three years using Linux distros, and though I use OSX now, I'm much more comfortable with general system administration than I would have been otherwise.

Having recently had to do some crazy commandline-fu (powershell and cmd.exe) to fix my Windows install, I have to say that there really is no comparison - linux wins hands down. Sure, part of it was familiarity, but it felt so clunky and awkward that I don't think thats all it was. The flexibility of bash, awk, sed, grep etc etc cannot be overstated, IMHO.

On another front, I've found Linux to be time saving, compared to Windows. For example, on a new install, on Windows I now have to hunt for the software I need from lots of different locations, download each one manually and install each one manually (and its impossible or awkward to automate, so you have to sit through a load of install GUIs - or switch CDs if its something proprietary that only comes on CD, though luckily I don't even remember the last time I had to do that, even my games are digital distribution games nowadays). On Linux, all the base stuff is "probably" (depending on your distro) already installed. The rest can be batch installed by a single command (pacman, apt-get, yum, etc) and you can then leave to do something else while you wait for it to install.

Similarly, Microsofts advertisements claim that Linux is difficult and time consuming to keep up to date - what with Windows Update and all. But we all know that on linux this is just a single command (pacman -Su, apt-get upgrade, etc) - this can, of course, easily be automated to run at certain times. Windows Update only updates Microsoft software - the Linux command will update all software installed through the package management system.

Of course, this doesn't invalidate the quote - you still spend time to make Linux do what you need, but you do on other operating systems too, so relatively to the non-free operating systems (which take the same or more of your time), Linux is, indeed, free.

The irritating thing about that argument is it comes with the built-in implication that you already know something else (Windows/OSX/whatever). It is basically complaining about learning-curve, right?

The other irritating thing is it usually 'means' general computer usage, but as hackers we need to choose OS's for things like server deployments, development environments, etc. In my experience when you start mixing in enough complex/worthwhile applications of the OS it becomes a wash in time consumption between *nix/Windows (since you are using the bulk of your time learning application-level things)

So if your doing something 'worthwhile' might as well go with the option that only costs 1 of the assets rather than three (time, money, and freedom)

You make an excellent point about the application-level learning, I actually noticed myself that I was spending a vast amount of time just configuring my OS and apps -- time which I could have spent actually producing things. This was my primary justification for buying my Mac, though I still think I learned a lot using Linux that I wouldn't have otherwise ...patience and perseverance, among other things.

Linux: great for developing, terrible for consumption.

Another thing is that most programming resources that I've come across assume a unix-like system.

Windows 7 is an excellent operating system but I do all my dev work on ubuntu.

There need be no real danger of it ever becoming a drudge, for any processes that are quite mechanical may be turned over to the machine itself. - Alan Turing

Douglas Adams' version of Hoare's make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies.:

their fundamental design flaws are completely hidden by their superficial design flaws. http://www.otostopcu.org/yazi/h2g2/b4c36.php

"There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult."

C. A. R. Hoare

"Once a new technology starts rolling, if you're not part of the steamroller, you're part of the road." - Stewart Brand

It's pretty lame that they closed this question just because it doesn't fit the Stack Overflow model and doesn't have a right answer.

Part of a moderator's job is to use judgment and ignore rules when it makes sense to do so. This is a great thread, and closing it (even after 600 posts) seems like a bad decision.

It is closed mainly because with 600+ answers, people weren't checking for duplicate quotes anymore. Keeping it open wouldn't really serve any purpose at this point.

(At least, that's what I would think. I've only been on the job for two days.)

A collection of great programming quotes from Alan Perlis (first recipient of the Turing Award):

My favorite comes from Gerry Weinberg: If builders built buildings the way programmers wrote programs, then the first woodpecker that came along would destroy civilization.

Loved this one:

Hofstadter's Law:

It always takes longer than you expect, even when you take into account Hofstadter's Law.

Do you create anything, or just criticize others work and belittle their motivations?

- Steve Jobs

There's another decent collection of quotes here:

In Jon Bentley's long-ago "Programming Pearls" column in CACM he had at least one "Computer Science by Bumper Sticker" column. You can find one in the collection_Programming Pearls_ .

One of my favorite code comments comes from qmail: /* NFS Dorks */
