The dumbing down of technology | Tony Lawrence | 2008 - 0 views

  •  
    I love this article. Lawrence is 60 and can perhaps afford to be sanguine, but I am glad he is warning the rest of us.
  •  
    Some quotable quotes here: "while we laugh at the guy who expected that his computer could be hooked up to his boom box to use the cd, he's actually just a bit ahead of us. Yes, ahead, not behind. In the future, he probably could get his computer to talk the boom box into transferring data from its cd." "When I was a teenager, I had a friend who made extra money testing and changing vacuum tubes in TV's and radios. Try earning money that way today- there is actually a very small market for that kind of thing, and there are still people who sell tubes and the like, but that market is pretty small. In the dumbed down computers of the future, there may still be a few antique machines kicking around here and there, but that isn't going to support very many of us." This is largely true and happening all the time. A programmer can use Python or Smalltalk without needing to know C (or Fortran or assembler.) A child can program in Morphic tiles (Etoys and Scratch)! We don't need to know the difference between a serial cable and a printer cable, or how to install a driver' it is all USB (or Bluetooth!) There are some gurus that program USB, but perhaps only a few hundred of them, and the rest of us just use it.

Nabble - Squeak - Beginners - Getting at the squeak beneath eToys? - 0 views

    Etoys has become a great branch of Squeak (it branched from 3.8, but in the course of its development for OLPC, it has gained some nice fonts and a nice toolbar, among other things.) It behaves in a slightly more mainstream way, in that Etoys users no longer save the Etoys images, just save the project file (which is referred to in help as "Keep a current project"). The Squeak image itself restarts pristine and untouched each time it is restarted. \n\nSqueakers and developers who want to save their whole image (window positions, preferences, the lot, in classic Smalltalk style) will want the save command in the World menu. Bert Freudenberg explains where the World menu is hidden.

Alarming Development : JavaScript is good enough | Jan 2009 - 0 views

  • It is impossible to build a hash table in JavaScript that works on arbitrary objects. You would have to manually allocate unique ID’s for every object and include them in the toString. So no collections in JavaScript. Adobe provides a true built-in hashtable in ActionScript 3.
  • Objects can function as sets and maps. Arrays can function as lists and iterators (generate an array when you need an iterator). More that good enough in this context.
  • VB also often compiles down to better MSIL than C#. It is also the only .NET language with first-class edit-and-continue Lisp-like debugging capabilities.

  • a good collection library should support a meta-object protocol with features like rejecting changes. This allows collections to be passed around as references,

    An old-fashioned language war, 2009 style. Visual Basic even gets a mention as "Lisp-like" (for its debugging.)

    • David Corking
       
      Simple but sweet. I doubt it wil beat Google Docs for attracting collaborating groups, but it might! Corporations may want to do something similar with their private storage. How do they avoid malicious macros propagating from one cloud user to the next?
  • VB users will see a new feature later this year, offering an upload service to those wishing to archive or run multiple OS/application stacks - in Sun's Cloud.
    • David Corking
       
      VB doesn't mean "Visual Basic" any longer. This is clever leverage, I think, and one that will be supported by the open source community, because the cloud specs are open documents.

      Schwartz gives the strong impression of an IT company _without_ its hand in your pocket. It is a similar attitude and reputation, though with proprietary software, rather than services (for free software), that seems to have made Microsoft so wealthy in the late eighties and nineties.

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.

JavaScript as a Functional Language | Ajaxonomy | 2009 - 0 views

  • there is a little bit of hand-waving involved in calling JavaScript a functional language. JavaScript is not a side-effect free language, nor is it an expression-based language (i.e., it is not value-oriented, but rather variable-oriented). There is no tail call optimization in any of the current implementations, so recursion must be kept shallow. And the list goes on. Truth be told, JavaScript is really one of the first hybrid imperative-functional languages.
  • Higher-order functions allow us to do functional composition,
  • Since JavaScript does not have "overloaded" functions, this type of functionality is usually simulated using manipulation of the function's arguments. Currying comes in handy because it allows you to do this manipulation in a much cleaner and more modular way.
  • ...1 more annotation...
  • Closures have quite a few applications in real-world JavaScript: event binding, callbacks, sorting, mapping (in the classical Lisp sense), and many others. In more modern JavaScript programming, you can find them almost everywhere.

      Soon you will be able to write scripts to install "Virtual Data Centers" There seems to be a temptation here to make a virtual data center as complex as a real one - perhaps that is necessary, but this technology is in its early stages. Right now, I wonder if a virtual firewall appliance is as secure or fast as a real one.

    Certain kinds of deployment are much more efficiently achieved with virtual servers. This article is a simple and almost hands-on introduction to the way a Sun Cloud deployment can be scripted or have another automated front end for deployment.

Issue 9007 - chromium - Crash on illegal instruction (temporary dependence on SSE2) - G... - 0 views

  • Comment 36 by agl@chromium.org, Apr 06 (45 hours ago) You can remove the SSE2 specific flags from the build and you'll still end up with a working browser. However, you can't run pixel-tests with such a browser because your outputs will be different. For everything else, it should be fine. Comment 37 by evan@chromium.org, Apr 06 (45 hours ago) There is no reason we really need SSE2; it's just a temporary workaround for bug 8475.
    • David Corking
       
      Will have to tweak the build by hand. This will no doubt be fixed before Chromium Linux goes to beta, but right now it is a disappointment, as the reported added speed of Chromium may be more valuable on older machines.
  •  
    For now, Linux builds of the chromium open source browser won't work on Intel and AMD processors from the early/mid 2000s (including my desktop PC :( )
