Herbert Simon - Wikipedia (en) - 2 views

  •  
    « Simon was among the founding fathers of several of today's important scientific domains, including artificial intelligence, information processing, decision-making, problem-solving, attention economics, organization theory, complex systems, and computer simulation of scientific discovery. He coined the terms bounded rationality and satisficing, and was the first to analyze the architecture of complexity and to propose a preferential attachment mechanism to explain power law distributions. »

Why LD_LIBRARY_PATH is bad, by David Barr (2001) - 2 views

  • This list is prepended to the existing list of compiled-in loader paths for a given executable, and any system default loader paths.
  • For security reasons, LD_LIBRARY_PATH is ignored at runtime for executables that have their setuid or setgid bit set. This severely limits the usefulness of LD_LIBRARY_PATH.
  • SunOS 4.x uses major and minor revision numbers. If you have a library “Xt”, then it's named something like “libXt.so.4.10” (Major version 4, minor 10). If you update the library (to correct a bug, for example), you would install libX11.so.4.11 and applications would automatically use the new version.
  • ...5 more annotations...
  • Linux, SunOS 5.x and most other SYSV variants use only major revision numbers. A library “Xt” is just named something like “libXt.so.4”.
  • Linux confuses things by generally using major/minor library file names, but always include a symlink that is the actual library path referenced. So, for example, a library “libXt.so.6” is actually a symlink to “libXt.so.6.0”.
  • The linker/loader actually looks for “libXt.so.6”.
  • run-time vs link-time paths
  • There's also LD_RUN_PATH which is an environment variable which acts to “ld” just like specifying -R.

Google Announces Plans To Bake Android-Like Web Intents Into Chrome | TechCrunch, 2011-... - 2 views

  •  
    « So what exactly are Web Intents? The name and the purpose are both similar to the Intents system that's present in Google's Android platform. In short, Intents allow two separate applications to communicate with each other, without either of them having to actually know what the other one is. Instead, they offer and listen for generic hooks. »

Hadoop! : Apache distributed computing ecosystem - 4 views

  •  
    « The Apache™ Hadoop™ project develops open-source software for reliable, scalable, distributed computing. The Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using a simple programming model. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Rather than rely on hardware to deliver high-avaiability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-availabile service on top of a cluster of computers, each of which may be prone to failures. »

The truth about REST, 2011-04-11 by Ian Elliot @ i-programmer.info - 7 views

  •  
    "[...] If you are a programmer in a hurry and just catch part of the conversation you might well decided that REST is trivial and fairly obvious - just use URLs to code remote procedure calls. This is 80% of REST but the remaining 20% is important and it is all a matter of how you organise the remote procedure calls. [...] If you take the "URLs are remote procedure calls" approach to web apps then you are free to invent as many commands or verbs as you like."
