I want to multiply two (big) numbers.
I found /usr/include/openssl/bn.h which has just what I need.
But everything is marked DEPRECATED_IN_MAC_OS_X_VERSION_10_7_AND_LATER.
So what is one expected to do in 10.9.2?
There is vBigNum.h in Accelerate.framework, but this does not help with
arbitrary
I've written a command line routine that compares two image files, in the hope
of determining if the two files are different. Basically the tool only compares
whether the dimensions are different or whether the pixel values are
sufficiently different. So the routine has a distance option which i
This has fixed itself. I don't know how or why. But after installing 10.9.2 and
rebooting the tiff files with varying alpha values look the same as png files.
I don't think it was the update to 10.9.2 but I've got no proof, but instead I
think it is related to the fact that I've occasionally had

That’s not a proper bignum; it has a limited precision of 38 decimal digits
(sounds like 128 bits?)
Gerriet: There must be a whole bunch of bignum libraries for C or C++; find one
of those and download and use it.

Well I've worked something out.
If the CGContext supplied buffer that the CIContext draws the results of the
CIAreaMaximum filter to uses float components it doesn't work. Providing a
context which is 8 bit ints per component with 4 components RGBA works.
Not the result I wanted, but at least I
That NSDecimalNumber is essentially the 128-bit quadruple-percision float
number, in an non-IEEE-754 fashion.
You can still use OpenSSL, either ignore the deprecation or compile and carry
your own copy. Apple deprecated it because OpenSSL API isn’t stable enough.
Alternatively, you can use othe
Thanks for your help. The problem is now solved - although I'm still none the
wiser as to why the problem only manifested when the file was opened and then
the document closed before the file was closed. I'm kind of curious to
understand what was going on under the hood that might explain this

The thing that I love about this site is that it always encourages developers
to be better, to do better. Awesome stuff. I also like the phrase
'programming by chance'!

Hello,
is there a way to stop NSKeyedArchiver from bombing out with an exception,
crashing the app along with it, when it tries to decode an archive that it deems
incomprehensible?
From time to time we get support requests about crashes that originate
basically in damaged archives (binary
Is there an NSNotification or some other kind of notification you can subscribe
to when there's a change in /dev? I'm dealing with an old USB-serial device
which creates a cu/tty when inserted (and removed when removed) and I'd like
to get a notification when that happens so I can update UI.

I've got a weird bug I'm having a hard time tracking down.
In an archive, I have an array of objects. In an earlier version of my app,
these are dearchived fine. In a recent build, they do not. The array is
returned, but it contains 0 objects. Using a delegate on the unarchiver, I can
see that
That's an idea. Not an Arduino, but not dissimilar, it's a UART mapped through
a Segger chip which presents as a USB CDC which the kernel grabs and turns into
/dev/cu.usbmodem* which required learning about termios and lots of other
things I've not had to think about in 20 years.

It seems that I can't sort on a read-only synthesized property in my
NSManagedObject subclass. I'd like to sort a bunch of stuff into some sections,
but the definition of a section is somewhat complex, depending on multiple
other properties. So, I defined a property "section" like this:

Yes.
