Almost every article I see that describes the difference between value types and reference types explains in (frequently incorrect) detail about what “the stack” is and how the major difference between value types and reference types is that value types go on the stack.

Fabulous Adventures In Coding : The Stack Is An Implementation Detail, Part One - 0 views

I find this characterization of a value type based on its implementation details rather than its observable characteristics to be both confusing and unfortunate. Surely the most relevant fact about value types is not the implementation detail of how they are allocated, but rather the by-design semantic meaning of “value type”, namely that they are always copied “by value”.
-
Of course, the simplistic statement I described is not even true. As the MSDN documentation correctly notes, value types are allocated on the stack sometimes. For example, the memory for an integer field in a class type is part of the class instance’s memory, which is allocated on the heap.

TestDisk - CGSecurity - 0 views

TestDisk is powerful free data recovery software, designed to help recover lost partitions and/or make non-booting disks bootable again -- particularly when these symptoms are caused by faulty software, certain types of viruses or human error (such as accidentally deleting a Partition Table). Partition table recovery using TestDisk is really easy!
Object Vs Model - 0 views

Data Hiding simply doesn't make sense with regards to a reflective system where the data must regularly be updated by observers of reality (i.e. by one or more actors) and where the data inherently comes from the outside. This is, perhaps, one source of ObjectRelationalImpedenceMismatch?. Relational is designed for modeling data that came from an outside world whilst object-oriented is designed to... well... create and manipulate objects

You can make them work together until you try to add virtualization - abstract objects for which the associated data isn't known.

it analyzes the file system directly and generates a Flash file that you can load locally or remotely on any Flash-supporting web browser. Torta uses Gordon, a library that provides flash generation functionality.

A very nice graphical front-end for 'du', in Common Lisp. I have tried it - it is trivial to use with SBCL. Version 0.3 works very well on the native Linux filesystem of my laptop, and on its VFAT (Windows) filesystem, provided I mount it with iocharset
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.
The APIs for the Sun Cloud: Wiki: HelloCloud - Project Kenai - 0 views

. Let's assume that this application does storage and retrieval of large media files; the required infrastructure is: A firewall appliance for connecting to the Internet A private network connecting the firewall to other systems A Linux web server running a LAMP stack A Solaris database machine running MySQL for application persistence A WebDAV server for the media files

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.
Programming languages usage ::TIOBE Index - 9 views
-
The TIOBE Programming Community index gives an indication of the popularity of programming languages. The index is updated once a month. The ratings are based on the number of skilled engineers world-wide, courses and third party vendors. The popular search engines Google, MSN, Yahoo!, Wikipedia and YouTube are used to calculate the ratings. Observe that the TIOBE index is not about the best programming language or the language in which most lines of code have been written. The index can be used to check whether your programming skills are still up to date or to make a strategic decision about what programming language should be adopted when starting to build a new software system.

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.
