Quote: John von Neumann "In mathematics, you don't..." - 105 views

Such a brilliant take-captures the essence of how abstract concepts become second nature with time Juwa backend, not instant clarity.

    Julia is a high-level, high-performance dynamic programming language for technical computing. It supports distributed parallel execution, numerical accuracy, and an extensive mathematical function library. It uses an LLVM-based JIT compiler to achieve near C performance that far outstrips Python/Matlab/R ...

    The Archive of Interesting Code is an (ambitious) effort on my part to research, intuit, and code up every interesting algorithm and data structure ever invented. In doing so, I hope both to learn the mathematical techniques that power these technologies and to improve my skills as a programmer. The examples on this site are in a variety of languages. I generally prefer to use C++ for algorithms, since the STL provides a great framework for expressing algorithms that work on a variety of data types. I code up most data structures in Java, both because the Collections framework allows them to be integrated in seamlessly with other applications and because automatic garbage collection simplifies some of the resource management. Every now and then I'll find an algorithm or data structure that is best represented in a different language like Haskell, in which case I'll forgo my usual language conventions.

    "Rx is a superset of the standard LINQ sequence operators that exposes asynchronous and event-based computations as push-based, observable collections via the new .NET 4.0 interfaces IObservable and IObserver. These are the mathematical dual of the familiar IEnumerable and IEnumerator interfaces for pull-based, enumerable collections in the .NET framework. "

    Exponents, integers, square root....do these sound like a foreign language to you? So maybe mathematics is not your best subject, and helping your child understand them may be outside of your area of expertise.

Programming as if Performance Mattered, by James Hague [2004-04-04] - 3 views

  • I frequently see bare queries from programmers in discussion forums, especially from new programmers, who are worried about performance. These worries often stem from popular notions about what operations are "slow." Division. Square roots. Mispredicted branches. Cache unfriendly data structures.
  • Inevitably someone chimes in that making out-of-context assumptions, especially without profiling, is a bad idea. And they're right.
  • The golden rule of programming has always been that clarity and correctness matter much more than the utmost speed. Very few people will argue with that. And yet do we really believe it? If we did, then 99% of all programs would be written in something like Python. Or Erlang.
  • ...5 more annotations...
  • At the same time, such concerns and advice seem to remain constant despite rapid advances in hardware.
  • That tempting, enticing, puzzle-solving activity called "optimization," it hasn't gone away either.
  • Only now the process is on a different level. It isn't machine level twiddling and cycle counting, but it isn't simply mathematical analysis of algorithms either.
  • The big difference is that the code changes I made are substantially safer than running a program and having it silently hang the system. All array accesses are bounds-checked. There's no way to accidentally overwrite a data structure. There's no way to create a memory leak.
  • Really, this is what those cycle-counting programmers from 1985 dreamed of.
