SHA256 hashing with secret key..

by sergio_101

hey, all... i installed the Cryptography library, and can produce a has like: SHA256 hashMessage: 'test' hex. the problem i am running into is, i need to generate the SHA256 with my AppKey from facebook. i can't figure out how to generate a hash using a secret key. i tried looking through the source code, but couldn't find anything for SHA256.. any ideas? thanks! -- ---- peace, sergio photographer, journalist, visionary http://www.ThoseOptimizeGuys.com http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Yes, that is a good idea as well, and not even as inefficient as it seams. But the selector is #readStream (or #writeStream). Actually, using ReadStream class>>#on:from:to: can solve lots of problems efficiently as well. -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

Select variable, CMD-R (for rename) and you'll have a refactoring window popup open. Restricted to variables..., but the whole process works without a single click of the mouse :)

Re: [Pharo-users] ZnLineReader set limit when reading a header

by Paul DeBruicker

It looks like the server they use internally (Mochiweb) limits them to 8k. So I can just override ZnContants class>>#maximumLineLength in my image to 8200 and be set.

Re: [Pharo-users] modal dialog

Hello Do you see Presenty? http://smalltalk-presenty.blogspot.com/ You can try it with prepared image at http://code.google.com/p/smalltalk-presenty In Presenty your example will look like: YourApplicationTask>>body some stuff... answer := user confirm: 'message'. ... And modal mode of confirmation dialog is just one specific setting of it activation which can be different for different parts of your application.

No, there currently is no per-request way to set the ZnConstants class>>#maximumLineLength. You can only override that method, it is just an intentional resource protection limit, making it 64k or so won't hurt (apart from allocating larger buffers). I guess I could make it globally settable. You're the first one hitting that limit ;-) Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

ZnLineReader set limit when reading a header

by Paul DeBruicker

When using the Phriak client I infrequently want to access all the keys in a bucket. When I do I sometimes get the ZnLineTooLong error because Riak returns the list of keys in the response header. Is there a way to set the maximum line length for the headers on a per request basis so I can change how the ZnClient operates while running Riak operations?

Re: [Pharo-users] Loading and using Designer

by StÃ©phane Ducasse

hubert this is not that we did not look at Designer. We look at it. Now it is based on signal and signal use thisContext all the times if I recall correctly. In Pharo we are removing event mechanism, to use announcements. And we did not want to add yet another event mechanisms. Then we would like to have a uibuilder like in VW based on the reuse of composable ui elements. This is why the rmod team payed benjamin during the summer and before to work on Spec and an UIbuilder. Now benjamin did a lot but now he should go back to university. So the work around UIBuilder is not something that we will stop but it will be more time than expected. Please note that understanding what we really wanted and analyzing the available solution took us time. Now we have a nice first version of the system. Stef
