ObjectIcon 2.4 and Cygwin make

ObjectIcon 2.4 is available at code.google.com/p/objecticon

This is the Icon language of the late Ralph Griswold and others as extended by Robert Parlett with class-based objects and Unicode.

If you are a Windows user with Cygwin as your gcc build environment, you will have to recall how to apply env var changes to the current shell: ObjectIcon comes with a handy paths.sh file which will only be of use if run as

.  ./paths.sh

where the initial dot ensures that a script not using exit will have its variables export into the scope of the current shell in which it will run.  Just running the script will not set the var's for ObjectIcon to use.

This way you are able to pick up the ObjectIcon env vars such as OIHOME without adding them into a bash rc file or the like.

On my system that paths.sh file is

# Object Icon path settings

export OIHOME="/cygdrive/i/objecticon-2.4"
export OIBIN="$OIHOME/bin"
export OILIB="$OIHOME/lib"
export OIPATH="$OILIB/main:$OILIB/gui:$OILIB/xml:$OILIB/parser:$OILIB/ipl"
export OIINCL="$OILIB/incl"
PATH="$PATH:$OIBIN"
LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$OILIB/native"
export TRACE OIMAXLEVEL

IE8 compatibility and leaks links

Microsoft has their IE8 compatibility page here at http://www.microsoft.com/windows/internet-explorer/readiness/developers.aspx

There is a useful discussion in the forum at http://social.msdn.microsoft.com/Forums/en-US/iewebdevelopment/thread/772e4b07-29e1-4909-b77f-f61c503f9579

A long-standing resource is quirksmode.org at  http://www.quirksmode.org/dom/intro.html

David Hammond's webdevout.net shows no blog post since July 24, 2009 at http://www.quirksmode.org/dom/intro.html but still has a lot of information.

The wikipedia quirks_mode article at http://en.wikipedia.org/wiki/Quirks_mode is also useful.

Camera Obscura and "Back to DSL"

With our re-location we are back to DSL as we are just past the area with Op Fiber to-the-door (this must be one of the few cities with free public wi-fi downtown and to cross the five feet with fiber.

Unlike the typical American publiv library in a small city, the public library here has a shelf of philosophy books both in Dewey 100+ and 180+ including one volume that was a very pleasant surprise.

The biggest treat: a hand controlled "camera obscura" in a dome by the river.  This is not augmented vision with adjusted focus as in a magnifiying glass, a spyglass, a telescope, a film camera or a video camera: this unique manner viewing a display ( I do not say "image") of reflections of the trees on the surface of a flowing river, passing gulls or tourists on the bridge - an artist's permanent installation - alone would be worth the journey.
