Hi Alex,
Following the design proposed by Stef, in your case you would use a different
collection.
Cheers,

Hi Stef,
You are raising an interesting point to discuss. This MissingValue is indeed
better than having -1
Something to keep in mind: it may be that one would like to focus on the
missing value and not really the value.
Consider:

Hi,
MissingValue (or NoValue) is definitely the way to go. The
UniformOrderedCollection is an interesting idea, too. We had a NoValue like
solution a long time ago but we discarded because we missed the idea around
collections. It would be really cool to have this working.
Cheers,
Doru

So basically you are trying to deal with missing values in collections.
People working with R or Python data analytics framework made some
ways to work with specific data structures called dataframes
where you can have some missing values.
For example you may have a look here:

Thanks - testing the new dylib (see response to Esteban) with a C app
(command line tool) as you suggested saved me from wasting time before
realizing I had a 64 vs 32 bit problem.. works now.
Cheers,

Thanks Esteban, was helpful to know I had (almost!) the right syntax..
With that I was able to concentrate on the library loading - apparently
using a .dylib rather than .bundle made the difference.
It now works - thanks again!

I'm currently trying it and it seems quite easy to load and use - just
working fine.
Of couse it seems kinda slow in comparison with native implementations (2000
iterations of SHA256 into 32 byte hash taking almost a second on my quite
powerful PC), but that's expected and not that much of a proble
Hi Jan,
I extracted a PBKDF2 implementation from some of my code some time ago.
Take a look here:

In Moose when we compute metrics it may happen than a tool (often external

I think I last used this in Pharo 1.3
#greaseString is just a cross platform #asString so you could change those
for your updated package.
here's a version of #randomBCryptSalt: that will work OK.

Hello Jan,
The latest commit of the Cryptography package loads in Pharo 5 without
affecting existing packages, but it does not guarantee that all the
methods are working.
The FFI related packages will likely not work out of the box, because
there was a change in the FFI interface from Pharo 4 to
Hi,
I never tested it with a “bundle” plugin. But if before it worked like this:
someNumber
^self externalCallFailed
Now it should work like this:
someNumber
^ self ffiCall: #(int someNumber () ) module: ‘ThePlugin’.
and:
a) you can do that with a FFILibrary child
There is a #random channel on slack, one can do a #politics one if so
needed.

I recently worked with UFFI for making a shared memory library, the very
first thing I have done is to do everything first with C code , to make
sure things work at the C side. Its so easy to mess up things at C code. So
first make sure that the library actually works, because if it does not
work i
Previously with NativeBoost, Pharo FFI diverged from the mainline VM,
which made support from vm-devs a bit harder.
In Pharo 5 we've returned to the fold with UFFI, but there are some
changes required.
I recorded my own learning of UFFI here...

In a 4.0 image I got in a situation where it seems Ring is out of sync (I am
getting errors of missing meta classes on each accept). I vaguely remember
there being an expression to reset/reinitialise Ring ?
Does anyone remember ?
Thx,
Sven
Yes this is why it would be a good addition to protego
