[Pharo-users] [ANN] Pharo Sprint 26 Feb

2016-02-17 Thread Marcus Denker

We will organize a Pharo sprint / Moose dojo Friday, 26 Feb, starting at
10:00am. (Local Time Lille).

It will be at the Inria Lille, Building B, third floor (RMoD offices).

Remotely, you can join us on Slack or the IRC channel #pharo on
irc.freenode.net  server. During the sprint, we will 
try to synchronize
local and remote Pharo sprinters.

As the building is not open to the public, please contact us before if
you plan to come.

2016-02-17 Thread Sebastian Heidbrink

Hi Thorsten,

I had already filed a bug report and the topic is under investigation.
I saw your post and I do not have further details yet, I just know that
Windows users should not replace their current images with the latest
images yet. Otherwise they might have trouble.

I wrote that Pharo images listed in the Launcher do not work. I did not
mention a particular combination of configurations.

I am sorry that I hijacked your thread. I work on all platforms but I
used Windows only past 4 days.

If you would like to follow the bug please visit:
https://pharo.fogbugz.com/f/cases/17541/PharoVM-crash-in-Moose-6-0-image-when-hovering-mouse-pointer-over-Roassal-View

Unfortunately, this issue is brand new and I couldn't write more details
on that except warm to wait for further info before upgrading images on
Windows 8.

Seriously you should rethink your way of COMMUNICATION:

1. This thread here is about a specific UNIX package and you tell us about a
general Pharo problem you seem to have on a completely different platform:
WINDOWS.

2. You "hijack" this thread instead of opening a separate one specific
to the problem and asking if others might have the same issue.

3. You "give a general warning" to others already to "keep their images"?

No details on what modification could possibly harm the image.

4. You talk about a broken Pharo 5 - but do not tell us what/where it is
broken.
Did the image not come up, is there a problem in a tool or when calling
something/using UFFI.
=>

5. You talk about "recent changes" without telling us when it started or at
a minimum with which image version you face the problem. When it worked
before then one can easily use Launcher to incrementally download and check
several images to find out which change broke something.
=>

6. You say you cant build a new image since a few days without giving any
information what packages you load or how you build your custom images.

7. You said that you used several combination of VM and images but
do not tell us which one you used/expected to work.
=>

Sorry - do you really think this is a good way to report a problem?
How do you expect someone to invest his sparse spare time to help you?
Maybe it is much easier to "just lament" instead of "being supportive".

As an info: I also use Pharo 5 (even latest images up to Pharo 5 #50586) on
Windows
with Spur since 2 months. Found smaller issues that I reported, most of them are
already adressed because I was able to give a clear picture of what the problem
was.

And yes - times are a little bit shaky because of Spur and UFFI - but this

was already announced/warned before and situation has improved a lot with
latest updates.

Please do us all a favour and open a new thread or much better a bug
report with exact details to reproduce if you have any finding.

Before that check your setup: for SpurVM you should try:
http://files.pharo.org/vm/pharo-spur32/win/stable-20151214.zip (which is the
Spur build from December)
http://files.pharo.org/vm/pharo-spur32/win/PharoVM-Spur32-win-latest.zip
(which is the latest CI built)
with the highest image build number: http://files.pharo.org/image/50/

For non-spur images (Pharo 4.0 and Pharo 5.0 up 50496 update) you need the old
non-spur VM: http://files.pharo.org/vm/pharo/win/

If you use Launcher check that you use the latest green build from
https://ci.inria.fr/pharo/view/Launcher
and that spur and non-spur Vm is correctly configured in the Pharo launcher
settings.

Thanks

Re: [Pharo-users] GSOC 2016 Application update

2016-02-17 Thread PBKResearch

Alexandre

I would strongly disagree with your first proposed change. In my understanding 
(English is my native language), 'popularity' is a mass noun, not countable, 
hence the 'an' is incorrect. Wiktionary, based on an ancient edition of 
Webster, allows the possibility of countable use, but the only example it 
quotes is archaic. At the very least, there is nothing wrong with the original 
version.

2016-02-17 Thread Sebastian Heidbrink


Hi,

I don't want to spoil the great news, but actually the most recent 
changes break Pharo 5.0 with SpurVM on Windows 8.


UFFI must have brought something in there that makes Pharo crash.

Windows 8 users should be adviced to keep their current working images.
I am lost since a few days since I can't built a new image that would 
actually work.
I tried several older snapshots of the VM and the Pharo images listed in 
the PharoLauncher but none work.

[Pharo-users] Writing a dictionary as XML?

2016-02-17 Thread p...@highoctane.be

How can I write a dictionary (OrderPreservingDictionary) as an XML string?

XMLWriter is more like a step by step thing.

TIA

Re: [Pharo-users] What are immediate subclass and word variable subclass?

2016-02-17 Thread Damien Pollet

Immediate means it's stored in the OOP itself, like SmallInteger in 32 bits.
Variable word is like variable byte (ByteArray) I suppose, variable size,
with indices instead of named instance variables, but each index points to
a full word (I guess either 32 or 64bit depending on the VM)

Re: [Pharo-users] gtoolkit 3.10 overview

2016-02-17 Thread Tudor Girba

Hi,

Indeed, the settings sending unknown messages is a problem, but that is a 
problem that is not related to Spotter. If you get it with Spotter settings, 
you will get it with all other settings as well. The settings mechanism should 
be more robust in my opinion.

Cheers,
Doru

thank you for the detailed changelog. Please pay attention to the
Settings system. I have the impression that what you did might forbid
you to remove any extension in the future. What I see happening is that:

1. people start deactivating some extensions through the Settings

2. they write their Settings in a file so the settings are available for
all images

3. in this file, settings are deactivated with Smalltalk code that send
setting-specific messages to specific objects

4. you decide to remove an extension and remove the corresponding
setting method

5. the user downloads the new Pharo and gets an error because his
setting file sends messages that are not understood anymore.

I have had excellent experiences with a compressed scrum, using a (near)
daily cycle where the student demos todays code and discusses steps for
the next day.


i am not very familiar with scrum. it was my understanding that daily standup
is part of a regular scrum. so you make a plan for a week or two, and talk

Yes. I found a scheduling horizon of two weeks way too far, especially 
when starting a project. Experiments need to be much smaller, and doing 
a daily demo of both successful and unsuccessful experiments helped 
uncover failures in mental models quickly.

i am not very familiar with scrum. it was my understanding that daily standup
is part of a regular scrum. so you make a plan for a week or two, and talk
about the progress every day.

this is what i did with my students last year. in the daily standup every
student reports what they worked on since the standup, and what they plan to
work on next. we did that on irc, so students would write their reports.
after the reports we discuss issues.

one issue i found is, that it gets a little one-sided if there is only one
student (i had two unrelated projects, so one student was alone, but i made her
report in the #pharo channel), so i would suggest to have all students join the
meeting at the same time and place. (slack is probably the best tool for this) 

then it's just a matter of finding a good time that fits everyone. maybe two
or three times will be better if pharo gets more than a few students.

however, having everyone join the same meeting helps show everyone how much
others get done, and generally should help foster community.

greetings, martin.

pharo applied last year too.

> Maybe this shoule be made clear...

how was this question answered last year?
the feedback from googles feedback session last year was that there were no
issues with the pharo application (there were just to many good organizations
to be accepted)

to explain the relationship to esug, it may be worth mentioning that at least 6
out of the 10 projects from 2012 were pharo projects. (one was VM, one was a
smalltalk tutorial, and two i could not tell from the description) 

in 2010 also most projects were pharo based or cross-platform

(for 2007 and 2008 i can't see the list, so i don't know) 

http://www.google-melange.com/gsoc/org2/google/gsoc2012/esug
http://www.google-melange.com/gsoc/org2/google/gsoc2010/esug

another way to look at it would be to count which mentors in previous years
came from pharo.

Thank you Sven.

I don't have time to fix the process at the moment.
I will just convert all the gsoc ideas as Markdown and there will be
available on github.

[Pharo-users] Line end convention in method source

2016-02-17 Thread Norbert Hartl

I had a strange effect using a method as storage. I had a list of strings that 
I compiled into a method. The strings were delimited by Character lf. I created 
this on a Mac. Saving the source and opening the same code on a linux machine 
changed the line endings from lf to cr. 
IMHO this is a bug because I think that the content of a method should be 
unchanged in that case. Or are there any other reasons why this is the way it 
is?

thanks,

Norbert

Last year a CI job was created:

https://ci.inria.fr/pharo-contribution/job/GeneratePharoTopicsPage/

I tried to revive it, but I can't find the config/settings, or so it seems.

Yes, it used to be STON, but it was changed to .st - in any case, the idea was 
that it were just objects.

I totally agree this process is not good.

The AWS bucket is under my private key, cannot share that.

Dear all,

just a quick update to GSOC application of Pharo this year

- We have enough topics I guess. I already send a reminder on the
various mailing-list.
List of topics here:
https://github.com/pharo-project/pharo-project-proposals/blob/master/Topics.st

We have to generate the html from the topics list and put the result
on the gsoc.pharo,org website. I ask Uko to have a look to this, but I
don't want to loose to much time on this. I was wondering if we should
transform the list as a Markdown document on github just to keep it
simple.

- Finish the 2016 Application and Organization profile on Google
website. The questions are a little bit different from 2015 and we
should complete them.
Please find below the answers to the questions right now.

I add in parenthesis, the number of words of each answers and the
maximum allowed.

Please us to refine our answers. We need to wrote "guidance for students".

Thank you.

Why does your org want to participate in Google Summer of Code? (898/1000)

Supporting open-source projects is one of the most important
objectives of the Pharo community. Participating at GSoC will increase
the visibility of Pharo project efforts, thus favoring interactions
with other communities. We are also interested in providing
interesting projects to students allowing them to learn and have a fun
job for the summer.

We expect also to bring more people into our community. That's very
interesting as the Pharo community is trying to be innovation-driven
and more open minded than the Smalltalk community from which we have
evolved. We want people from other communities to join ours and we are
also interested in what is happening outside and to share experiences
or ideas. Fortunately for us, dynamic languages like Python, Ruby,
among others, enjoy increasing popularity. This is an excellent
opportunity to join, show and learn from and with other communities.

==

How many potential mentors have agreed to mentor this year?

11-15

==

How will you keep mentors engaged with their students? (668/1000)

We chose mentors from people who are long time in our community and
have proven to be reliable. Usually we try to match mentors with
projects that are important for themselves. This means that the mentor
has an own interest in the project that the student doing it. Also we
try to ensure that there is a co-mentor for every project who can
replace the main mentor if needed. Also it is very important for us to
keep a good record and expand the community, and in previous years we
even managed to organize our own "summer code" programs for a couple
of students, so in the worst case we will find a replacement from the
core part of the community, or the board itself.

==
How will you help your students stay on schedule to complete their
projects? (886/1000)

As mentioned before we've already organized our own small "summer
code" programs, as usually we have more interested students than the
fundings that we can spend for them. However we acknowledge that
maintaining student's motivation is very important. We are a very open
and friendly community, and we encourage the students to take part on
the mailing list discussions from the beginning of their projects.
There is a specific pharo-users mailing-list more suitable for
beginners than the pharo-dev mailing-list.
Usually students get feedback and requests from the beginning of their
projects, and they have people interested in the prototypes as soon as
they are ready. From our experience having real users for the project
serves as the best motivation. Also our mentors try to maintain a
constructive and friendly discussion to ensure that the student enjoys
working on the project.

==

How will you get your students involved in your community during GSoC?
(608/1000)

As mentioned above we encourage students to announce their status on
the mailing list as well as discuss questions on our Slack channel. We
also encourage them to write blogs about their project experience to
both promote themselves and give others an opportunity to familiarize
with the project more and share ideas between students. We are
organizing PharoDays every year (this year in Belgium, website:
http://pharodays2016.pharo.org) and we participate to the ESUG
(European Smalltalk User Group) conference in the end of each summer
and plan to invite
