Re: [Pharo-users] Voyage and Instance Mode

by Dominique Dartois

Thanks Esteban. I was fooled by the doc : "In instance mode, the first argument is always the repository on which to performed the operation"... Well, not really, but the object to store.

Voyage and Instance Mode

by Dominique Dartois

Hello all. I'am learning to use Voyage by trying the examples in the Voyage doc (in the Enterprise Pharo book). I read "By default, Voyage works in instance mode". If I run the example in instance mode, I get an error via the debugger. |repo anAssociation| repo := VOMemoryRepository new. anAssociation := #answer -> 42. anAssociation save: repo. ==> "Instance of Association did not understand #save:" What am I doing wrong? -- Dominique

[ANN] Reed Solomon and Forward Error Correction

by henry

I spent time straightening out Foward Error Correction, using Reed Solomon encoding with Galois Fields. I mostly have it working for some algorithms, but still have an issue with AZTEC_DATA_10, and perhaps AZTEC_DATA_12. AZTEC_PARAM, AZTEC_DATA_6 and AZTEC_DATA_10 ar working, as well as DATA_MATRIX_FIELD_256 and QR_CODE_FIELD_256. I do not know if it is pluganizable, that would be super if code split into image and plugin, naturally. I have more testing to do to get those couple of algorithms working, then I will turn to QRCode and get that working. Thank you. Here is the code... http://www.squeaksource.com/Cryptography/fec-HenryHouse.7.mcz - HH

The problem is not specific to using ZnClient, it is with every loop you execute in the UI thread: the Transcript output is not updated (as it is the UI thread itself that has to do the drawing). For example, try 1 to: 10 do: [ :i | Transcript crShow: i. 5 seconds wait ]. The solution is to run you long running code in another thread, like this [ 1 to: 10 do: [ :i | Transcript crShow: i. 5 seconds wait ] ] fork. HTH, Sven

Lengthy operations block UI

by Andrei Stebakov

I have written some code that has a deep nested loop of calling ZnClient>>get. In the loop I also execute Transcript>>show but I can only see the transcript output after a few seconds when the loop is finished. During all that time while the loop is busy the UI is also unresponsive. Is there a way to execute code in some sort of asynchronous way?

Here, just load PharoLauncher-Core-ChristopheDemarey.172 and it will do the job. PharoLauncher bleedingEdge is also available here: http://files.pharo.org/pharo-launcher/bleedingEdge/ but is not always up to date because the build process also build 64-bits images and loading code in 64-bits image fails at least 4 times / 5 tries, so resulting artifacts are not published. I wonder if I should remove 64-bits build for now.

Thanks Christophe, Is there a way to update my existing Launcher image or should I wait until you release a future binary (no problem, I can wait). Thanks!
