I need a programmer familiar with USB IO and InterfaceBuilder in OS X
to help me with a worthy cause.
I'm trying to read an ultrasonic distance sensor that streams data
into a USB port. The sensor is hand-held. I will use it to measure the

I was wondering if someone could help me get to grips with the controller
layer concept, my being new to os x development. I have tried using an
NSController class to bind simple text field controls to a model with no
problem. I have also followed the example for the ...

I've shifted to XCode recently from CodeWarrior (well, I'm in the process :)
and I've run afoul of some build errors in my freshly created Carbon based
static lib project that I wasn't hitting before. Specifically, I had
previously included some code in a C++ file that declared and ...

The first time the application is running (just after Xcode build)
Horizontal Scroll bar work correctly. If the window grow past the
larger text in the last column, the Horizontal Scroll bar disappear
but never re-appear when the window shrink.

Hi Kids,
I want a custom view that serves as a drop target for all kinds of
images, like NSImageView does, but I want to add the ability to click
and drag a selection rectangle.

Howdy.
A few days ago (POSSIBLY in conjunction with the Security upgrade) my
Terminal started, for output data, when you type an O or an L followed
by a slash, showing a single character, a slashed L used for the "W"

FSCopyObject problems. This is in the current version 1.4
FSCopyFile with kDupeActionReplace does a FSDeleteObject at the end even
if the deleteMeRef is not set. It's set in the call to SetupDestination
only if there is already a file with the same name. Otherwise it's left

I'm trying to build the sample code from Stevens UNIX network
programming on OS X 10.3 . Unfortunately the configure script fails as
it is unable to determine the host.
I guess the problem is that the config.guess (and associated files) are

I've been struggling to cross compile my command line tool in Panther
for Jaguar, and have come to another progress stopper.
My tool uses the dynamic linker library libdl (since it is used by
libcurl). In Jaguar, I had to install libdl, but in Panther, the

I am trying to port a command-line tool that comes from linux, but I have
a problem: it uses the readline library, which is not installed on Mac OS
X. I installed it with fink, but I do I specify in the source files where
that lib can be found?

I just upgraded to Panther and installed the latest development tools
which includes Xcode.
The user interface for Xcode is quite a bit different from Project
Builder, and I am having a hard time finding documentation that

Howdy - I'm an old pre-OS X programmer looking to finally dive in.  Back
when my wife got her Ibook I downloaded the development tools and took
an initial look, but just didn't have the time at that point to hang
with the learning curve.  Some new books for Christmas got me ...

I have been using this function and its converse for years and I only just
noticed that there appears to be a serious error in its function.  The
value component always comes back equal to the blue component without
regard for the red or green components at all.

I'm about to get a mechanical device with a USB interface,
for which I have source for a Linux driver.  Under Linux,
it looks like you fill in an 8 byte block, and then use
an ioctl() call.  I know what to put in these blocks, and

Does anyone know what exactly would enable a PP view to draw over a
floating window?
I'm using a variant of Gabriele de Simone's LTooltipAttachment class.
It works fine so long as the floating "tooltip" window is drawn
