Converting between Word and Byte Array
by Lars 11 Jul '12

11 Jul '12

Hello, I'm at the moment working with ARM code, and the most convenient way to create memory chunks with instructions is word wise, by creating WordArray instances. But for some primitives, it would be better to have ByteArrays, because all pointers are byte-offsets. So borders have to be multiplied by 4, etc. Is there a convenient way to create one from the other? The 'asByteArray' or 'ByteArray newFrom:' both don't do the job. Thank you, Lars

Installing Smalltalk's (COG VM and/or Gemstone) on a NAS (Synology) ?
by Cédrick Béler 09 Jul '12

09 Jul '12

Hi all, Has anybody ever tried to get Smalltalk on a NAS box ? NAS are more and more present around me and I can't help thinking it would be a great smalltalk deployment option. Out of the box, PHP application can run. I think one problem is the multitude of architecture and that each VM needs to be compiled specifically. As a side note, I think we should focus on Synology and Qnap at starts. Let's take a particular example. I have a synology NAS (DSM 411+II) wich is based on an ATOM 510 (64bits if I'm correct) [2]. There's a guide on how to install third party application (from the raw setup to the app packaging) [3]. From what I understand of the compilation process [3], the first step is to download DSM Tool Chain [4] and to use it to compile sources on a classic linux station. Then, once compiled, you move the executable to the NAS and it should work... Problem is I'm a bit lost there because, first I never compiled a VM and second, this needs some manipulations on the configure file (which I'm not at ease with). So, is there a brave experienced soul that could have a try compiling a Cog VM with this toolchain (my NAS is a pineview processor - D525)? Also, I think this would be even more pertinent with gemstone. I tried the install.sh but got quickly blocked and I'm not sure this gives a single executable anyway. But if the gestone guys wants to have a try... :) I can give ssh access for people interested if necessary. TIA, Cédrick [1] http://blog.synology.com/blog/?p=1070 [2] http://forum.synology.com/wiki/index.php/What_kind_of_CPU_does_my_NAS_have [3] http://download.synology.com/download/ds/userguide/Synology%20NAS%20Server%… [4] http://sourceforge.net/projects/dsgpl/files/

Return strings in numeric primitives
by David Leonhardt 03 Jul '12

03 Jul '12

Hey. I'm doing my own numeric primitive. I could return numeric values, doing something like: self pop: 1 thenPush: ( objectMemory integerObjectOf: 21 ). What I couldn't do is find a way to return a string, for example 'Hello World'. Thanks, David.
