Re: [Pharo-users] Scratch in Flash or Phratch?

by Alain Busser

Alas, although I live on Reunion Island since 25 years, I don't speak Creole. But the creole language in Scratch has been written by people from Quebec (!). And was incomplete yet funny. I miss it... Anyway thanks, I can work with Phratch in French without having to install anything (I don't have the admin rights) Alain On Sun, Oct 12, 2014 at 4:01 PM, jannik laval <jannik.laval(a)gmail.com> wrote: > Hi Alain, > > Yes, Phratch is in french (almost all blocks are translated). > As I don't speak creole, I cannot do it. > > If you can do it, just take te attached file and replace all the french > sentences by creole ones. > Then, send me the file, I would be happy to integrate it in the release. > > Cheers, > Jannik > > > 2014-10-12 14:12 GMT+02:00 stepharo <stepharo(a)free.fr>: > >> ask jannik directly. >> >> Stef >> >> On 12/10/14 08:03, Alain Busser wrote: >> >>> Hello, >>> >>> I must present Scratch to my pupils on Tuesday, and I want to show to >>> them the French and Creole versions.

Hi Alain, Yes, Phratch is in french (almost all blocks are translated). As I don't speak creole, I cannot do it. If you can do it, just take te attached file and replace all the french sentences by creole ones. Then, send me the file, I would be happy to integrate it in the release.

have you tried Phratch ? it has French in its language menu (the globe icon). Dont know about Creole.

Scratch in Flash or Phratch?

by Alain Busser

Hello, I must present Scratch to my pupils on Tuesday, and I want to show to them the French and Creole versions. But Scratch is not programmed in Squeak anymore. Rather, it is in Flash. Hence my question: Is there a French version of Phratch? And will there be a creole version before tuesday? The advantage of Pharo is that it doesn't need an installation and I can share it easily with the pupils. Alain

Re: [Pharo-users] About Zinc http components

by Alain Rastoul

Hi Phil, Yes, multi core support and communication is important, having that in pharo could be great. Unfortunately, no I actually have no usable project for that, mine is not a communication project and still really in pre-alpha stage. For now, I'm starting with Zinc, 0mq is just from a prospective eye. I have no experience with 0mq, I discovered it just few days ago (see Marten's messages), but it seemsto be easy to use. What I did is just read the echo server sample, and threw few lines in a workspace to see how it works (here modified to send/receive 8k pages instead of echoing the message). I am also interested in something more elaborate , as I will probably use it later, I will think about a simple test project (the workspace here is just a very first experiment) and see what I can do. The bindings are FFI, may be it should be rewritten/modified to use native boost (I know only the name here). If you want to look here it is, it's very basic and only the REQ/REP pattern (not sure the other works, I tried but the vm hanged, may be my fault, may be it also requires more work). You have to load Panu 0mq bindings before and put a zmq.dll in your path. The server (kill the server with Process browser to stop it) "====================================== classic sockets - REQ/REP server" [ | context serverSocket request count | [ count := 0 . context := ZmqContext new . serverSocket := ZmqResponseSocket new. serverSocket bind: 'tcp://*:5555' . [ true] whileTrue: [ request := serverSocket receive . "fake request" serverSocket send: (ByteArray new: 8*1024 ). "block response" count := count+1 ]. ] ensure: [ serverSocket close. ('server exited -', count asString, ' pages sent ') explore ] ] forkAt: Processor "systemBackgroundPriority" userBackgroundPriority "lowIOPriority hangs" . The client (5 sec bench of request/reply) : "======================================== classic sockets - REQ/REP client" [ | context socket response count bench | [ context := ZmqContext new . socket := ZmqRequestSocket new. count := 0. socket connect: 'tcp://127.0.0.1:5555' . bench := [ socket send: 'get xxx' asByteArray . "fake request" response := socket receive . count := count + 1 ] bench . ] ensure: [ socket close. bench explore. ('client asked for ',count asString) explore ] ] forkAt: Processor userBackgroundPriority "lowIOPriority" .

Re: [Pharo-users] About Zinc http components

by phil＠highoctane.be

Alain,â Yes, 0mq seems to be a good way to go as there is just more support across the board. Have you a project on Smalltalkhub (or elsewhere) with your experiments so that I could have a look? I've updated the 0MQ bindings page to list the smalltalkhub pharo client and also had a look at what was in the GST client. It would be nice to port the GST code to Pharo so that we would have a nice package. 0mq could help with the multicore support very nicely. We are going to use SDL for low level, why not go 0mq for interimage communication? It makes sense to me. Phil

Re: [Pharo-users] About Zinc http components

You are lucky that you hate windoom sometimes, I hate it all the time :D Yes as I said I am very happy so far with StreamSockets and I have found ways to minimise the socket communications so that the user don't experience any noticeable lag so I don't currently need either 0mq or nanomsg. So its unlikely that I will be wrapping nanomsg any time soon since my hands are already full with bringing Blender features to Pharo. I have done some very basic benchmarks with StreamSocket and it gives me around 1ms from the messages I am sending which is usually just small bytestring of one line of python code. It will be rare to want to send more than 100 messages in under a second since it would be better in that case if the code is that big to write a python module from pharo and load it to python. So speed for now does not seem an issue for me. Even if I notice delays my second option will be websockets. And if that is not good enough I could venture in the real of shared memory but I rather not. There are many things one wishes and wants to do, but in the end time is very limited. I also love to keep things easy and simple because I know how easy it is to underestimate the difficulty of things to do. Right now I ask myself what is the very easy things I can do with Pharo that can be practically useful for me. So far python and pharo sockets have been very easy and I am very happy with them. Its a lot of fun to manipulate external applications from pharo.
