Quotes About Efficiency

Flash cards are like legal anabolic steroids for learning with no negative side effects.

Norvig: I think one of the most important things is being able to keep everything in your head at once. If you can do that you have a much better chance of being successful. That makes a small program easier. For a bigger program, you need extra tools to be able to handle that.

But in the meantime there's no reason to starve the users for [syntactic] sugar. It doesn't rot their teeth and it helps them avoid mistakes. — Brendan Eich

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

Peyton Jones: For me, part of what makes programming fun is trying to write programs that have an intellectual integrity to them. You can go on slapping mud on the side of a program and it just kind of makes it work for a long time but it's not very satisfying. So I think a good attribute of a good programmer, is they try to find a beautiful solution. Not everybody has the luxury of being able to not get the job done today because they can't think of a beautiful way to do it.

Things have gotten faster but the software has gotten slower and buggier in the meantime.

I can't say beginner programmers should open up all these abstractions. But what I am saying is you should certainly consider the possibility of opening them. Not completely reject the idea. It's worthwhile seeing if the direct route is quicker than the packaged route.

Seibel: How do you read code you didn't write? Crockford: By cleaning it. I'll throw it in a text editor and I'll start fixing it. First thing I'll do is make the punctuation conform; get the indentation right; do all that stuff. I have programs that can do that for me, but I find doing that myself is more efficient in the long run because it gets me more acquainted with the code.

Moore's law doesn't apply to batteries. So how much time we're wasting in interpreting stuff really matters there. The cycles count.

you only got 80 words to write your routine, and so you do tend to use things like reusing instructions as data, using a piece of data for more than one thing. If you can manage to put this little subroutine there in memory, then its address can also be used as a data constant. This is what it took-it was origami and haiku and all that as a style of programming. And I spent several years doing that.

It takes twenty-one pounds of protein fed to a calf to produce a single pound of animal protein for humans. We get back less than 5 percent of what we put in.

You have to have more leadership, less management. It's about getting stuff done, you can sit around and analyze things forever but while you do that the competition has moved on.

What keeps earth air breathable? Not oxygen alone. The earth is a freer place to breathe in, every time you love without calculating a return -- every time you make your drudgeries and routines still more inefficient by stopping to experience the shock of beauty wherever it unpredictably flickers.

Add to that the age-old principle of Ockham's razor in problem-solving: "If there are a number of possible solutions, the simplest one, based on the fewest assumptions, is most likely to be correct.

31Days2GetOrganized).

Keeping flat surfaces clear is perhaps the single most important thing to keep in mind for your kitchen—as it is for any room in the house. A clear countertop makes any kitchen look more organized. Once the flat surfaces start to disappear under clutter, you lose your motivation to keep the area organized and you open the area to attracting more dust and dirt, further compounding the clutter problem. Consider flat surfaces your preparation area—not your storage area!

Not sure what you use and what you don't? Here is a tried and true way to find out. Empty the contents of your kitchen utensil drawers into a cardboard box. For one month, only put a utensil back into the drawer if you take it out of the box to use it. At the end of the month seriously consider discarding everything that's still in the cardboard box. Face it: If it's still in the box after four weeks, you don't need it!

Perfect hexagonal tubes in a packed array. Bees are hard-wired to lay them down, but how does an insect know enough geometry to lay down a precise hexagon? It doesn't. It's programmed to chew up wax and spit it out while turning on its axis, and that generates a circle. Put a bunch of bees on the same surface, chewing side-by-side, and the circles abut against each other - deform each other into hexagons, which just happen to be more efficient for close packing anyway.

There's no such thing as survival of the fittest. Survival of the most adequate, maybe. It doesn't matter whether a solution's optimal. All that matters is whether it beats the alternatives.

Turns out that when something gets cheaper, or more efficient, we just end up using so much more of the stuff that the savings disappear under a wave of increased consumption. They call it the "Jevons Paradox"

If you've got the senses and reflexes to hide between someone's saccades, why stop there? Why not do something that really works?

There's no such things as survival of the fittest. Survival of the most adequate, maybe. It doesn't matter whether a solution's optimal. All that matters is whether it beats the alternative.

And frankly, if IT isn't helping you operate how you want—and need—to operate, you are wasting money. There is no chance that your IT investments will lead to strategic benefits.

In a new plant for even established processes or products, there will probably be a shake-down period of six to eight weeks that will prove rather expensive. It takes this long to get the equipment adjusted to the required operating efficiency and to weed out the inevitable "bugs" that seem to occur in breaking in modern intricate machinery.
