This can result in a design that is not as clean as it could have been or code that is incorrect, because the code is complicated by the optimization and the programmer is distracted by optimizing. (c) by Donald Knuth Naomi Nosonovsky, Sr. Programmer-Analyst My blog Tuesday, September 7, 2010 6:41 PM Premature Optimization is the Root of All Evil! "Premature optimization" is a phrase used to describe a situation where a programmer lets performance considerations affect the design of a piece of code. In a few FORTRAN codes I have, the original programmers made use of boolean short circuiting. Its source is credited to Donald Knuth . It’s all highly scientific now: I have moved ... Beware of the evil … Their guidance helped me in all the time of research and writing of this thesis. Premature optimization is the root of all evil. So I said I’m going to formalize my training and get a piece of paper which shows I can do ... I’d like to preface this discussion with the comment that premature optimization is actually the root of all evil. Structured Programming with go to Statements, ACM Journal Computing Surveys, Vol 6, No. I agree wholeheartedly. 細かな効率については、約97%の場合忘れれば良い。なぜなら、時期尚早の最適化は諸悪の根源だからだ。 Translation notes: I just translated "say about" as 約.

Premature Optimization is the Root of All Evil H/T: @lpolovets Donald Knuth was specifically talking about algorithms in computer software, but the lesson applies broadly to product development, startups, and self-improvement. Keep the spotlight on Time. Premature Optimization is the Root of all Evil Donald Knuth was indeed right when he said that, "premature optimization is the root of all evil." A good programmer will not be lulled into complacency by such reasoning, he will be wise to look carefully at the critical code; but only after that code has been identified. As Knuth said, We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. What’s more, the time and energy spent on optimization is wasted as our work changes. There's plenty of 'evil' in statistics that doesn't relate to optimization. — Donald Knuth对于程序优化，我一直采取保守的态度，除非万不得已。但是随着业务的不断发展，程序越来越复杂，代码越写越多，优化似乎是终有一天会到来的事情。那么对于一个典型的后台服务接口，我们可以从那些方面入手进行优化呢？ "We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil." (Knuth, Donald. Be mindful of premature optimization. As a result, optimization or performance tuning is often performed at the end of the development stage. str is supposed to be user-readable, and repr is more technical, e.g. Good technical design is primarily about balancing several interrelated requirements. The blog post quotes Donald Knuth who said “Premature optimization is the root of all evil.” For sizable projects, premature optimization is practically procrastination.

A lot of the postings in this section of Java Ranch strike me as worrying about performance far too early in the system's life cycle. The Second Rule of Program Optimization (for … This is a classic case of premature optimization. I don't know that I agree with the statistics paraphrase*. 667–673 Share It makes no difference to state that something is half quicker on the off chance that it was at that point quick enough to begin. Mark-Jason Dominus.

Yet we should not pass up our opportunities in that critical ... but tracking down the origin of this quote I found that it was actually Knuth who said … Premature optimization is the root of all evil. A wiser man than myself once said: We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. This is going to be a very short chapter, because the main thing Unix experience teaches us about optimizing for performance is how to know when not to do it. However, when supplying the entire quote, these people sometimes actually become more convinced that what I'm doing is Premature Optimization™ and dig in and refuse to listen. We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. • Center of attraction.

We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Premature optimization is the root of all evil in programming. 4, Dec. 1974. As computer scientist Donald Knuth rightly said: “Premature optimization is the root of all evil.” We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Premature optimization is the root of all evil A model for evolving your organizational design. In my experience it's used more as an excuse for writing sloppy code that is obviously horribly inefficient, or to otherwise rail against making changes that aren't deemed necessary for whatever reason e.g. Page 2. “Premature optimization is the root of all evil.” ― Donald Ervin Knuth, The Art of Computer Programming, Volume 1: Fundamental Algorithms Premature optimization is the root of all evil September 6, 2020 October 11, 2020 Rohit Leave a comment An antipattern that I see in startups constantly is Senioritis .

Looking for abbreviations of POITROAE? ... to DigitalOcean platform: they provide a decent virtual server for $5/month, with static IP address to boot. It is time consuming and, by definition, “premature”, so it is not a good thing to do. The best implementation would be clear, efficient and simple.
