Clonezilla - 0 views

  •  
    Clonezilla is a PXE network boot used to clone multiple computers at once - much like norton ghost.  Clonezilla Live is a bootable CD/USB image that can replace the need for a network boot server and image host, allowing you to clone a single machine on a local computer without a network.

Microsoft released beta of Windows Vista compatibility Update - 0 views

  •  
    The Platform Update is a set of runtime libraries which bring Vista largely up to par with Windows 7 in terms of the: Windows Ribbon control; Automation Manager Library; DirectX updates for hardware acceleration; DirectCompute for hardware-accelerated parallel computing support; the XPS printing library; the Windows Automation API; and the Windows Portable Devices Platform, which standardizes data transfers across apps and portable devices.

Joe Duffy's Weblog - OnBeingStateful - 0 views

  • The biggest question left unanswered in my mind is the role state will play in software of the future.
  • The biggest question left unanswered in my mind is the role state will play in software of the future. That seems like an absurd statement, or a naïve one at the very least.  State is everywhere: The values held in memory. Data locally on disk. Data in-flight that is being sent over a network. Data stored in the cloud, including on a database, remote filesystem, etc. Certainly all of these kinds of state will continue to exist far into the future.  Data is king, and is one major factor that will drive the shift to parallel computing.  The question then is how will concurrent programs interact with this state, read and mutate it, and what isolation and synchronization mechanisms are necessary to do so?
  • Many programs have ample gratuitous dependencies, simply because of the habits we’ve grown accustomed to over 30 odd years of imperative programming.  Our education, mental models, books, best-of-breed algorithms, libraries, and languages all push us in this direction.  We like to scribble intermediary state into shared variables because it’s simple to do so and because it maps to our von Neumann model of how the computer works.
  • ...3 more annotations...
  • We need to get rid of these gratuitous dependencies.  Merely papering over them with a transaction—making them “safe”—doesn’t do anything to improve the natural parallelism that a program contains.  It just ensures it doesn’t crash.  Sure, that’s plenty important, but providing programming models and patterns to eliminate the gratuitous dependencies also achieves the goal of not crashing but with the added benefit of actually improving scalability too.  Transactions have worked so well in enabling automatic parallelism in databases because the basic model itself (without transactions) already implies natural isolation among queries.  Transactions break down and scalability suffers for programs that aren’t architected in this way.  We should learn from the experience of the database community in this regard
  • There will always be hidden mutation of shared state inside lower level system components.  These are often called “benevolent side-effects,” thanks to Hoare, and apply to things like lazy initialization and memorization caches.  These will be done by concurrency ninjas who understand locks.  And their effects will be isolated by convention.
  • Even with all of this support, we’d be left with an ecosystem of libraries like the .NET Framework itself which have been built atop a fundamentally mutable and imperative system.  The path forward here is less clear to me, although having the ability to retain a mutable model within pockets of guaranteed isolation certainly makes me think the libraries are salvageable.  Thankfully, the shift will likely be very gradual, and the pieces that pose substantial problems can be rewritten in place incrementally over time.  But we need the fundamental language and type system support first.

MIT's Introduction to Algorithms, Lectures 22 and 23: Cache Oblivious Algorithms - good... - 0 views

  • Cache-oblivious algorithms should not be confused with cache-aware algorithms. Cache-aware algorithms and data structures explicitly depend on various hardware configuration parameters, such as the cache size. Cache-oblivious algorithms do not depend on any hardware parameters.
  • An example of cache-aware (not cache-oblivious) data structure is a B-Tree that has the explicit parameter B, the size of a node. The main disadvantage of cache-aware algorithms is that they are based on the knowledge of the memory structure and size, which makes it difficult to move implementations from one architecture to another.
  •  
    « Cache-oblivious algorithms take into account something that has been ignored in all the lectures so far, particularly, the multilevel memory hierarchy of modern computers. Retrieving items from various levels of memory and cache make up a dominant factor of running time, so for speed it is crucial to minimize these costs. The main idea of cache-oblivious algorithms is to achieve optimal use of caches on all levels of a memory hierarchy without knowledge of their size. »

Pragmatic Smalltalk (slides) | Feb 2009 | David Chisnall - 0 views

  •  
    Interesting clippings from the slides: "What can we do with it? * Write applications. Melodie uses lots of Smalltalk, first pure-Smalltalk app committed to svn in January. * Write scripts. Corner activation and gesture app uses Smalltalk for scripting. * Modify existing apps... " "We can inspect classes in a code browser, see method names, and write replacements in any running application. In a perfect Free Software system, any user can make any changes. "
  •  
    My comment above might imply that Smalltalk is not modern. The truth is far from it, as Smalltalk is still pushing the boundaries of technology and user interfaces, from Croquet and Qwaq, to Alice, Sophie, Scratch and Etoys.
  •  
    (I fixed Friday's broken link to the PDF.) From what I read so far, this seems to be another attempt at a fully introspecitve integrated and customisable personal computer with a graphical desktop. In other words, it is Dynabook Smalltalk and Lisp workstations all over again, but quite likely with some interesting modern twists.
