Pharo on Windows Issue

Robert Calco — 2012-04-30T13:43:38

Hi Janko,

This is not a big deal, and it's not anything new either. The screenshot is
from a fresh Pharo 1.4 image on Windows after loading Aida 6.4. After a few
minutes a #messageNotUnderstood message pops up.

Basically whenever out-of-the-box Aida runs some periodic task it calls
ExternalWindowsOSProcess#value on Pharo for Windows (v 1.3 and 1.4), and it
fails here (see the part in red):

| procInfo mainThread |
self isNotYetRunning ifTrue:
[procInfo := OSProcess accessor primCommand: self commandLine.
procInfo isNil
ifTrue:
[self initialStdErr nextPutAll: 'cannot execute ', self commandLine; cr.
self exitStatus: #cannotExecuteCommandLine.
"FIXME: Close the OSPipes now, otherwise the image will block on a read"
self closeStreams.
[self complete] fork "defer execution so OSPipes stay in place for now"]

Apparently the call to self#initialStdErr fails to return an object and
nextPutAll is sent to a Nil object, which doesn't understand that selector.

In general the code in that method looks dodgy (several

preferredUrl problem ?

Dirk Verleysen — 2012-04-09T09:14:34

On my Team class I have a preferredUrl that combines the class name with 
the id. When I add a new team this nil and I get this url.
http://football:8888/teamnil <http://dram242:8888/distillerynil>

This is no problem but after working on adding new teams I suddenly get 
this url and I have to restart my SwazooServer to make it work it again.
http://football:8888/object/o8356866.html 
<http://dram242:8888/object/o8356866.html>

After this I can work again for about an hour before the problem occurs 
again.

Any idea what is going wrong ?

[GSoC] Call for students

Janko Mivšek — 2012-03-28T08:48:17

Dear Students,

Now it is your turn! You will have to register in our website first [1],
put there some information, show interest for the projects and contact
the project mentors. After the registration step you will get all the
mentors information in order to contact them. By pressing the button on
the project, you will show your interest. This is not something formal yet.

Of course you can propose your own project too. In this case write a
proposal in a format other projects have and send it to admins (see the
email on the bottom).

Our mentors will vote for the most interesting projects and in the
middle of the voting Google will tell us, how many projects will
actually be funded. Voting will happen in April, with final results
expected at the end of April. At that time you will finally know if you
are accepted or not.

Of course, there can be many students interested per project. This means
that interest for this project is high, but on the other side a chance
that you will be chosen is lower.  It is u

Janko Mivšek — 2012-03-12T19:02:45

Hi Sebastien,

For a site named 'aidademo' try:

SwazooServer singleton removeSite: (AIDASite named: 'aidademo')

You need to send #removeSite: to instance and not a class of
SwazooServer. And because there is only one instance (singleton pattern)
you reach it by 'SwazooServer singleton'.

Yes, that button to remove a site is sooner or later necessary in
Admin->Settings->Sites tab...

Good luck!

Newbie question about registering sites.

sebastien paquet — 2012-03-12T18:24:03

Hi, I know how to add a site from the workspace but I can't find the right
way to remove a site. I know that the default has to be registered first
before you can do anything so I thought about removing it would be the same.
I tried using : " AIDASite removeSite:'aidademo'. I tried using SwazooServer
removeSite:'...' . Different other things too. It's funny because I did it a
couple days ago. But I don't remember what I did exactly. I even thought
about adding a button next to the sites names in the settings in the admin
panel, well,next to where it says "Add new website". Thanks in advance.

Re: Amber + Aida?

Janko Mivšek — 2012-03-11T12:18:03

Hi Sebastian!

I think your question can be divided in two questions:

  1. REST API support in Aida
  2. Amber and Aida integration

1. REST API support
-------------------

Aida is REST-like framework respecting the Central principle of REST [1]:

"An important concept in REST is the existence of resources (sources of
specific information), each of which is referenced with a global
identifier (e.g., a URI in HTTP). In order to manipulate these
resources, components of the network (user agents and origin servers)
communicate via a standardized interface (e.g., HTTP) and exchange
representations of these resources (the actual documents conveying the
information)."

In Aida a Resource is a domain object, representation is by default an
HTML page done by object's App as presenter. And each domain object can
have its own URL.

Forthcoming Aida 6.5 is introducing presenters for JSON and XML and
adding support for building full RESTful web services to communicate
with Aida from REST clients using additional PUT a

Hi Sebastien,

Welcome to the list and thanks for your kind words!

About Blog tutorial, yes this one is quite old and you are very welcome
to upgrade the tutorial and also the blog code itself to work on recent
Aida and Scribo. Maybe Nicolas Petton, author of the Scribo Blog will
find some time to help you too.

HI,

I recently started using Aida and learning Smalltalk at the same time
and I have to say that I really believe in a great future for this
framework and where it could go.

I just did the blog tutorial that used to be on the Aida site and where
the link is broken. I squinted my eyes over the clip on Youtube and did
it. I realized that a couple things in the docs on the site and
tutorials seem to have changed. I mean code wise. Sometimes I ll do
exactly what It says and it doesn t work. I ll try something else and it
does. I guess it could be related to the versions but I m not sure. So,
I wish i could contribute and maybe write down the blog tutorial from
the video, it s really good for showing how CRUD operations integrate
with the framework. Also how to route the views.

Aida is awesome and not that Seaside is

GSoC idea: Improving the GSoC website

Janko Mivšek — 2012-03-10T18:51:18

Hi guys,

To help the GSoC admins but also mentors and students, maybe this would
be a good project to do. Would someone help being a second mentor?

Improving the GSoC website
--------------------------
Level: Intermediate
Possible mentor: Janko Mivšek
Possible second mentor:

Description

Our special website for Smalltalk GSoC (http://gsoc2012.esug.org and
more complete past http://gsoc2010.esug.org) has a public and
administration part to help running the annual GSoC process smoothly. It
helps students, mentors and administrators in all phases, from
collection of ideas, preparing the projects, inviting the students,
pairing them with the projects, voting, running the projects with the
interim and final evaluation. This project is meant to improve both
public and administration part of the website to ease the work for
everyone and to upgrade it to the most modern web technologies.

Technical details

Possible improvements: Facebook like timelime of personal page adding
realtime updates (using WebSockets),

Subject: Amber + Aida?
To: Aida/Web Smalltalk Web Framework

Hi guys,

if I understand things right Aida is REST and Amber <http://amber-
lang.net/>[1] is hungry of a REST server-side counterpart.

There is also this Seaside REST<http://code.google.com/p/seaside/wiki/
SeasideRest>thing [2] and even
Kaliningrad<http://gemstonesoup.wordpress.com/2011/10/08/kaliningrad-
developing-w...>[3] for developing Amber and persist code in the
server side.

This all makes sense.

So, here my question is:

given that Aida is *a natural born REST server*, do we have an Aida
option
to work with Amber?

any experiences to share? ideas on how to do it? advantages found in
Aida
vs. SeasideRest for this goal?

Few Aida on Swazoo benchmarks, Pharo and VW

Janko Mivšek — 2012-02-27T12:56:55

Hi guys,

Encouraged by recent Philippe's benchmarking I did similar on Aida with
Swazoo web server, adding the comparison of Pharo with VisualWorks.

Results are interesting, Pharo is now only 3x slower than VW on dynamic
page generation but on network layer it is the same or even slighty
faster, while it was around 10x slower on Squeak back in 2008 [1],

Results (requests/s)
--------------------

1. Dynamically generated 3KB login page  (/admin?view=login)

       VW:  120,  Pharo:   40   ratio: 3x

2. Aida ping with zero size response (/ping.html)

local: VW: 4700,  Pharo: 4500   ratio: 1,04x
lan:   VW: 4500   Pharo: 4600   ratio: 0,97x
inet:  VW: 4000,  Pharo: 3000   ratio: 1,33x

3. Aida ping with 8K response

local: VW: 2600,   Pharo: 3100  ratio: 0,84x
lan:   VW: 1400,   Pharo: 1400  ratio: 1,00x
inet:  VW:  140,   Pharo:  140  ratio: 1,00x

Note: network saturation!

Preparing Aida for Cloud Foundry

Janko Mivšek — 2012-02-16T18:58:10

Hi guys,

Just FYI, James Foster from Gemstone (ok, VMware) is writing a series of
articles how to put a Smalltalk into a cloud using Aida 6.4 OneClick
image as an example. Very interesting read and even more interesting
work for us, so I'm hardly waiting for the next article in this series.

http://programminggems.wordpress.com/2012/02/14/preparing-smalltalk-for-cloud-foundry/

VMware's Cloud Foundry (http://www.cloudfoundry.org/)  can actually
become a "cloud of choice" for Aida web apps sooner that expected :)

Offray Vladimir Luna Cárdenas — 2012-02-14T16:21:28

Hi All,

Is nice to see this new year activity with the new year and is nice to 
see this focus in documentation. Making the connection with the 
greetings message from Janko apropos of the last year, 2011 was the year 
I discover Aida and made the decision of learning web development. I 
like a lot Aida, but because of the lack of comprehensive newbie 
oriented documentation and my lack of knowledge to help filling the gaps 
on this matter, my choice was to learn Seaside (which I like also, by 
the way). Now I want to comment on the documentation matter a little 
more, and if this mail gets too long (and is probable), I will try to 
publish parts as supporting material in other places.

First a little of context: I'm a teacher of Information and 
Communication Technologies (ICT) seminars on a postgraduate studies in 
Science Didactics, in BogotÃ¡ - Colombia, South America. My students are 
mostly school teachers without prior knowledge of programming and the 
more we deal with the social aspects of digita
