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

optimization low-level erlang

shared by Fabien Cadet on 01 Nov 09 - Cached
  • 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.

programming assembly language low-level

shared by Fabien Cadet on 01 Nov 09 - Cached
  • In fact, generated code can be so ridiculous and verbose that I finally came up with an across-the-board solution which works for all compilers on all systems: I don't look at the disassembled output.
  • I still see people obsessed with picking a programming language that's at the top of the benchmarks, and they obsess over the timing results the way I used to obsess over disassembled listings. It's a dodge, a distraction...and it's irrelevant.

Design Patterns: 15 Years After the Revolution, by Danny Kalev @ InformIT [2009-10-30] - 1 views

  • by defining a description template that included among the rest: Known uses. Sample code (as opposed to a typical algorithm which were often described in plain English and perhaps a few sketchy lines of pseudo-code). Collaboration (A description of how classes and objects used in the pattern interact with each other). Consequences (results and side-effects). Related patterns.
  • Would a 2009 catalog of the 23 classic design patterns look much different? According to the authors of Design Patterns: Elements of Reusable Code, the answer is no.
  • The authors would reclassify certain patterns and omit a few of the original patterns but the design and implementation would remain pretty much the same: "We have found that the object-oriented design principles and most of the patterns haven't changed since then" says Erich Gamma. You can't escape the feeling that patterns are frozen in time
  • ...2 more annotations...
  • In the meantime, in the C++ world the tide has turned towards a completely different paradigm known as generic programming (and to some extent, functional programming). Instead of plain classes and a complex inheritance chain, C++ these days uses templates, meta-programming and static type checking. The C++ Standard Library is the most prominent showpiece of the generic and functional programming idioms.
  • Over-engineering is another source of criticism. Programmers who become acquainted with patterns are often tempted to solve every problem using a pattern, even when a much simpler solution would probably be a better choice.
