Re: [Pharo-users] Recommended VM on Raspberry Pi ?

by ClÃ©ment Bera

Hello Sven, You can use the VM with the JIT on the Pie now (Spur Cog VM). It is deployed by default on the recent raspberry pis and has millions of users for Squeak and Scratch since August 2015 (the raspberry pie fondation paid Tim for the ARM JIT on the Cog because of the size of their user base). As far as I know there is no way to build it in the Pharo VM branch. Just pick a version compiled from the trunk, that should work fine with the latest Pharo 5 (note that it requires a Spur image, so it needs one of the latest Pharo 5). Here is where you can get it: http://www.mirandabanda.org/files/Cog/VM/VM.r3427/cogspurlinuxhtARM-15.33.3… Now even with performance improvement of the VM, some people reported that the UI of the Pharo image is too slow to be usable on the raspberry pi 1 (Nautilus takes *many* seconds to open for example, same for GT tools). Try and report your experience. On many benchs, the JIT VM for the pie has been reported on average 3 to 5x faster than the Stack VM. Note that the new FFI, even if it reuses the VM FFI backend, is dependent on x86, hence you need to use the old FFI syntax to have it working on the raspberry pie (there is some code to load in the image to do so). Have fun and report your experience with the raspberry pi and Pharo please, Clement 2016-02-12 23:05 GMT+01:00 Sven Van Caekenberghe <sven(a)stfx.eu>: > Hi, > > I have been using the PharoS VM for a Pharo 4 based app on Raspberry Pi > (Rasbian). > > This VM is quite slow. > > Now that Pharo 5 is Spur based, what is the recommended VM on that > platform ? > > I was hoping to use a faster VM, if that is available. > > Is anyone having some concrete experience in this area ? > > Thx, > > Sven > > >

Re: [Pharo-users] OS(Sub)Process on Raspberry Pi ?

by ClÃ©ment Bera

The latest FFI uses the old VM FFI which works on x86 and ARM and a new front-end which is seemingly x86 dependent. So OSSubProcess will work if you use FFI, but the old syntax not the new one. 2016-02-13 0:23 GMT+01:00 Mariano Martinez Peck <marianopeck(a)gmail.com>: > Hi Sven, > > Since OSSubprocess uses the latest FFI, it works only in Pharo 5.0 AND > Spur (and after certain Pharo 5.0 release).

Re: [Pharo-users] OS(Sub)Process on Raspberry Pi ?

by Mariano Martinez Peck

Hi Sven, Since OSSubprocess uses the latest FFI, it works only in Pharo 5.0 AND Spur (and after certain Pharo 5.0 release). So you should grab latest Spur-based Pharo 5.0 for OSSubprocess. Since Raspbian is based on Debian, I guess it should work (OSSubprocess uses libc), but I cannot tell as I don't have a Raspberry Pi here. If you get a Spur based Pharo 5.0 image and VM working in Raspberry Pi I can help you to see if it works.

Recommended VM on Raspberry Pi ?

by Sven Van Caekenberghe

Hi, I have been using the PharoS VM for a Pharo 4 based app on Raspberry Pi (Rasbian). This VM is quite slow. Now that Pharo 5 is Spur based, what is the recommended VM on that platform ? I was hoping to use a faster VM, if that is available. Is anyone having some concrete experience in this area ? Thx, Sven

OS(Sub)Process on Raspberry Pi ?

by Sven Van Caekenberghe

Hi, What is the state of OS(Sub)Process on Raspberry Pi ? I want a Pharo application to be able to execute some (simple, no IO) OS commands on Raspbian. Can that be done ? Does it work for Pharo 4, 5 ? What should I load ? Thx, Sven

Re: [Pharo-users] CDB project

by HernÃ¡n Morales Durand

Hi Nicolas, Thank you for checking. The reason why I ask is because such limit is important for bioinformatics. Next-Generation Sequencing (NGS) machines are generating bigger files (these are typically FASTQ files) everyday, have a look at this cdbfasta forum http://seqanswers.com/forums/showthread.php?t=15331 for an example of what's happening. Maybe the CDB designers didn't anticipated genomes would be available today. However, it's a nice project and is an important library.

Hi, Thanks for the question, Tbh we didnt even think about bypassing it. Still we gave it a though because of your mail and we feel like doing so would create some problems. Mainly because its already coded like that in other languages, and a >4GB files wouldn't be able to be used with other languages so it would be restricted to pharo.

The whole process is not automatic. The code to convert the .ston file to the .html is in http://www.smalltalkhub.com/#!/~Pharo/PharoPeople/ Maybe you can try to run it yourself. Once there is a new .html file, I have to put into some AWS S3 bucket of mine. If you send me the .html I will do copy it to the right place. > On 12 Feb 2016, at 12:57, Serge Stinckwich <serge.stinckwich(a)gmail.com> wrote: > > The sync with the http://gsoc.pharo.org/ is not working ... > Can we fix that and put GSOC 2016 on the front page ? > > Thank you > > On Thu, Feb 11, 2016 at 3:29 PM, stepharo <stepharo(a)free.fr> wrote: >> Good initiative. >> I will clean some of them too. >> Stef >> >> Le 11/2/16 15:20, Damien Cassou a Ã©crit : >> >>> Serge Stinckwich <serge.stinckwich(a)gmail.com> writes: >>> >>>> I reuse the list of the last year : >>>> >>>> https://github.com/pharo-project/pharo-project-proposals/blob/master/Topics… >>> >>> I've just removed everything git-related because it was old.

The sync with the http://gsoc.pharo.org/ is not working ... Can we fix that and put GSOC 2016 on the front page ?
