[Pharo-users] Magritte Tutorial [Draft]

[stepharo]

Hi guys

Here is the ci of the magritte tutorial that I'm revising and collecting 
material for


https://ci.inria.fr/pharo-contribution/view/Books/job/Magritte/lastSuccessfulBuild/artifact/book-result/BookletMagritte.pdf

If you want to add a chapter let me know.
I will add the ticketCorner and/or conference registration one in the 
future.

I see you trying to steer without situational awareness.
The great goal is clear, but there are bumps on the road and there is no 
direct road to Rome. Your analysis of the situation is superficial and 
not helpful.


Marketing is most effective if it is aligned with strategy.
I was serious about you having to make those Wardley maps.
It all starts with user needs. Take a look at where new smalltalkers can 
come from (students, old smalltalkers using something else, software 
reengineering specialists, people from small languages who want an IDE 
for it, people dissatisfied with their current large community language, 
etc), make some persona for them so it gets easier to imagine what their 
needs might be. Do the same for the people in our community 
(Researchers, independent developers, small group in a large high-tech 
company, legacy smalltalk group etc).


To understand and explain why and when they might be persuaded to use 
smalltalk, read
Mary Lynn Manns & Linda Rising, Fearless Change, Patterns for 
introducing new ideas

Geoffrey A. Moore, Crossing the Chasm
and possibly
Mack Hanan & Peter Karp, Competing on Value

From those user needs, make Wardley maps breaking down user needs in 
technology and community needs, making them more and more concrete. 
Identify what we support, where there are gaps and overlap, and what 
changes to expect.


Then decide where you can with minimal effort have the most impact and 
focus your marketing message there, using a positive story. Measure 
impact, see what changed and repeat.

[stepharo]

why don't you spend the time to write such mails into
- writing tutorial or
- just improving class comments of the well-known classs (such as 
set, dictionary, booleans, strings),

- create videos
you would have already an impact.
Now you are shouting in the desert and people will just put you on their 
black list.

bingo !!!
+1.000.000.000

The problem is that there is so much hype about marketing thats easy to
miss the enormous fact that languages like C, C++, Java and Python are not
as popular as they are even with their big flaws without substance ,
without solving some serious problem that requires serious resources .
Foremosts those languages have been evolving for decades , take Python

and I am NOT talking the language itself I am talking the most popular
python implementation and the oldest , CPython, its 24 years.

Let me repeat this...

CPython IS  24 years OLD 

There is none smalltalk implementation that I am aware of that has been
actively developed for so long even though smalltalk as a language is far
older than that.

Now imagine where Pharo will be in 24 years wow it blows my mind
just trying to imagine.

And by the way Python had ZERO marketing , ZERO Zero funds, zero 
no money nada. nothing

Just one dude working his ass off to make a great language for scripting C
projects.

So in the end its all hard work, as it should be .

So back to work improving Pharo :)

In the realm of marketing, having a clear objective is key, to unlock 
the artifact. Being a kid about it, to dig deeper into the inspirations 
of otexport LD_LIBRARY_PATH="/lib:/usr/lib:/usr/local/lib"hers, ignites 
it.  The kindling, however, must be a positive mental attitude (as 
espoused by bad brains). Critique is great, but allowing emotions to get 
behind being negative, let's it run that way.  What's positive? YOu can 
tell every new person that they add to the integrating capacity of a 
growing modern cloud meta system, with 9 layer stacks and clustered 
graphs of networked actors...real time.


Go for the multi-objective genetic approaches, really and truly. That's 
the best AI.

robert

Re: [Pharo-users] Metacello cannot download the latest zip of a github repo if a zip already exists from a previous commit

Thanks Dale , good news it works on Pharo 5 :)

Is there a way to delete the previous data = delete the previous zip file
and all its decompressed folders / files ? I can do it manually but I was
wondering if metacello offers anything similar.

Yeah I am interesting to this too, I was not aware Dr. Geo was on Android
thats great news.

as my Christmas present to myself :)

I would love to see a blog post by you how to get Pharo working on Android
and iOS . Any pointers ?

what do i need, how do i start?

i am tentatively working on a desktop application, that in the long term i
would like to see on the mobile phone, and i'd appreciate any insights and

But fast growth also has its problems...
https://www.groovehq.com/blog/scaling

Particularly see point 1) "Scaling Shifts Your Team’s Focus"
I believe Pharo is still in a stage where it needs a lot of agility.
IF there was suddenly a large influx of newbies, then EITHER:
* the experts spend *all* their time answering newbie questions and
not moving the platform forward (with a wider pool of disruptive
opinions)
OR...
* the newbies are ignored, get a bad experience, leave, and then "tell
everyone else about it".

Currently early adopters of Pharo get the benefit of great support
from a direct line with the experts, which enhances their good
experience which they can report to others.   However it takes time to
grow a community to have a range of middle experience levels to buffer
the experts so they can continue to do *real* work to drive the
platform forward.  No matter how much you do on marketing, you can't
get away from the reality that sustainable *community* growth takes
time.

But you don't reach critical mass until the library ecosystem is
sufficient for the masses.  Its catch-22.  This "bring them and they
will build it" has similar trouble as you concern against "build it
and the will come".

But if you can serve some limited domains very well, maybe you get
enough funds to provide time to build a broader library ecosystem.

Re: [Pharo-users] PharoJVM

[Hilaire]

For iPad, it is gone because I did not renew my developer license, so
Apple remove it from the store. Sorry sorry :(

Concerning DrGeo on Android, I mostly forgot all the details to build it
as I did not update it since a couple of years (3 years).
Historically Dmitri Golubuvsky helped me a lot to build it [1].  But I
don't think he's working on it anymore.
Later Jannick Laval asked me how I did the DrGeo for android, he wanted
to try for Pratch, he wrote some notes you may find useful [2]

You may want to check the former source repository containing Android
package for Dr. Geo, I just open its access for you [3]
You may need the event VM glue code[4], not sure this is the most recent
one.
I am just writing from memory, so I may forget some key points.


However, in the long term a lot will have change in Pharo on Android:
- What I did was before Athens, I don't think Athens is working now on Android
- Bloc will very likely replace Morph, and it may be the think to use for 
Android perspective.

[Pharo-users] Metacello cannot download the latest zip of a github repo if a zip already exists from a previous commit

[Dimitris Chloupis]

So it looks like that when I do

Metacello new baseline: 'ChronosManager'; repository:
'github://kilon/ChronosManager';  load

and I have ChronosManager already installed via the same command previously
, if the repo has changed in the mean time , it wont get the latest zip
from github and instead will use the existing zip to overwrite my image
(Not cool at all).

Obviously a bug ?

Re: [Pharo-users] PharoJVM

[horrido]

That's an *enormous* amount of work!!!  No wonder it hasn't been done yet. 

I did identify one thing: get high school students (i.e., young people)
interested in Smalltalk. That's why I tried (and failed) to launch the
Canadian Smalltalk Competition. You should understand that I put a LOT of
work into this, *a great deal of sweat and tears*. You have no idea. (Just
ask David Buck of Simberon.)

I'm only one person; I can only do so much by myself. And unfortunately, I'm
coming to the end of the line.

desktop app ready first, which won't happen before the next GSoC, (but it might
happen as part of it)) but i appreciate this information being available.

[Pharo-users] Machine Learning in Pharo

[Evan Donahue]

I saw a post on pharo-dev a little while ago about adding some machine
learning libraries to pharo, and I was just wondering if there have
been any developments on that front. I'm about to do some machine learning
work myself, so it might make sense to coordinate with anyone out there
already working on it.

Cheers,

[Pharo-users] New web tutorial

[stepharo]

Hi guys

with Olivier Auverlot we did several attempts (over the year) and we are 
happy to release a first draft of a web tutorial

around Pharo. We ask the user to build a simple blog engine.

It goes over
- Mongo
- Seaside
- Magritte

https://ci.inria.fr/pharo-contribution/job/TinyBlogTutorial/5/artifact/book-result/output.pdf

Soon Rest/Deployment/Garage?/NeoJSON/XML

If you want to participate (translate it to english) or improve it you 
are welcome.


We hope that it will serve as a basis to a lot of Seaside applications.

This tutorial will be used in the lecture I'm giving next weeks in Togo 
and will be edited as a lulu book.


Stef and Olivier.

"Fast growth has its problems." I don't think we need to worry about that. 

Even if we're successful with a marketing campaign, it will take time to
aggregate substantial numbers of new Smalltalkers. It may take years to
reach the top 20 on Redmond. (We should be so lucky to have this problem.)

Building an ecosystem is not about funding. Developers (and businesses)
write new and useful libraries out of need *when they choose to use your
programming language*. Ask yourself this: Smalltalk, in its various
flavours, has been used commercially for more than three decades. After all
this time, why are there still useful libraries missing, libraries that you
find in the Java and Python worlds?

Can you honestly tell me that over the next 5-10 years, we'll see the gaps
in our library ecosystem filled in? I wouldn't bet my lunch money...

Re: [Pharo-users] Metacello cannot download the latest zip of a github repo if a zip already exists from a previous commit

Obviously a bug ?
No it is intended behavior ... to avoid downloading the entire zipped

changes up on github), the cache is not flushed unless you do a `get` 
command as follows:


  Metacello new

load

(you probably need to use the latest version of Metacello, as well)

I see that I haven't documented this feature and that is "not cool at

ago, so users have finally caught up with me and it's time to update the

I have to say I kind of think Pharo is missing the boat with regards to mobile

one to write a mobile app that runs the same on Android and iOS.

I thought so, too, which is why I wrote  this tutorial

  
for app development. However, there is some question surrounding Amber's
viability in the longer term. 

And the demand for cross-platform apps may not be as big as we believe...

Re: [Pharo-users] PharoJVM

[horrido]

I think I asked this before (at the start of the year), but if I were given
an actual real-world *enterprise* customer /whom I could interview/ to get
the *full story* of how they came to use Smalltalk, especially if they were
coming from a major language such as Java, and what their particular
corporate issues were that compelled them to look for a better solution,
then I could run with it and write a lengthy story highlighting the unique
advantages of Smalltalk in solving these issues. It would be a huge
marketing tool /because readers (hopefully, enterprise users) could identify
with the story/ and see themselves following the same trajectory toward
Smalltalk/Pharo.

Perhaps somebody at ESUG or Pharo Consortium could provide such a reference?

As a person who has posted video of Squeak and Pharo running on

Squeak works well on the Pi, in my experience.  It's about an

On web you can already can use pharo for both the backend (server) 
and front

end (browser-javascript-html-css)

So Pharo has already spread on all major platforms , with the 
exception of
Android where there is still work to be done to make it usable. In 
the dev
list there was already an announcement for hiring a developer for 
one year

to work on the Android. So Android is a matter of time too.

For anyone that really cares about JVM in general as I already 
posted he/she

can take JNIPort and improve it anyway he/she wants.

Its not hard to create support for other languages if one wants to. I
created support for python, another dude created support for R 
programming

language who followed a similar approach to mine.

But we all have personal reasons and needs for using pharo with other
programming languages, I use it to script Blender the 3d application 
that

happens to use python as its scripting language, other may use R for
mathematical computations, other do web development, others want to 
make

Android apps and so forth.

Its impossible with such small community to fit the needs of every

Of course the one thing that you fail to mention is that no JVM based
languages (including Scala) can be called a popular language since 
they dont

even make the top 20.

I have personal experience with Python , Jpython is a port to JVM 
and not
only that JPython is special in a way that not only can use any 
Java library
out of the box but also has support for CPython libraries (which by 
very far

the most popular python implementation out there) and still its barely
alive.

The irony is that in the end people that are mostly interested 
about JVM
or JS are JS and JAVA coders mainly. Coders from other language 
tend to
stick with their own language mainly because both Java and 
Javascript though

both incredible big platforms they are both a huge mess.

Redline was a good effort that now looks like abandonware. Amber is 
barely
active. Those are common patterns for pretty much any language that 
decides

to embrace JVM or JS as platforms.

And you can use java libraries from Pharo via JNIPort

http://www.smalltalkhub.com/#!/~JNIPort/JNIPort

https://sites.google.com/site/jniport/project-definition

I wanted to use python libraries from pharo , I did not go to 
implement
pharo or port pharo to Cpython, all I did was to create a 
communication
bridge via sockets and I did that in less that 100 lines of python 
code.


Its easy , fast and simple. Nothing stops anyone from interfacing 
pharo
with any popular platform or other language. The fact that people 
prefer to

stick with pharo frameworks and libraries sends a clear message.

Invest in Pharo , this is what our community is focused on.

I've shipped several cordova/phonegap apps.  

It can work for a certain level of simplicity - but browser based apps don't

I would be more interested in being able to develop a browser based app in 
Pharo and deploy it to a phone or tablet.

It happens consistently when I serialize via:

I can send you the image if necessary. I'll PM you if we can't figure it

On web you can already can use pharo for both the backend (server) and front
end (browser-javascript-html-css)

So Pharo has already spread on all major platforms , with the exception of
Android where there is still work to be done to make it usable. In the dev
list there was already an announcement for hiring a developer for one year
to work on the Android. So Android is a matter of time too.

For anyone that really cares about JVM in general as I already posted he/she
can take JNIPort and improve it anyway he/she wants.

Its not hard to create support for other languages if one wants to. I
created support for python, another dude created support for R programming
language who followed a similar approach to mine.

But we all have personal reasons and needs for using pharo with other
programming languages, I use it to script Blender the 3d application that
happens to use python as its scripting language, other may use R for
mathematical computations, other do web development, others want to make
Android apps and so forth.

Its impossible with such small community to fit the needs of every user of
pharo or potential user, so it wont happen until like me you are ready to
get your hands dirty to make Pharo work well for you. Else you are better
coding in other language .

Hello

The question isn't how to implement Pharo in JVM. I know Java programmers
will never use Pharo as I probably will never use Java.

The question is to spread Pharo all over the platforms. And the more
extended platform all over the world are IOS and Android. The advantage is
to have Pharo not only the computer but also in our personal tablets (no
phones nor phablets).

Asunto: Re: [Pharo-users] PharoJVM

Of course the one thing that you fail to mention is that no JVM based
languages (including Scala) can be called a popular language since they dont
even make the top 20.

I have personal experience with Python , Jpython is a port to JVM and not
only that JPython is special in a way that not only can use any Java library
out of the box but also has support for CPython libraries (which by very far
the most popular python implementation out there) and still its barely
alive.

The irony is that in the end people that are mostly interested about JVM
or JS are JS and JAVA coders mainly. Coders from other language tend to
stick with their own language mainly because both Java and Javascript though
both incredible big platforms they are both a huge mess.

Redline was a good effort that now looks like abandonware. Amber is barely
active. Those are common patterns for pretty much any language that decides
to embrace JVM or JS as platforms.

And you can use java libraries from Pharo via JNIPort

I wanted to use python libraries from pharo , I did not go to implement
pharo or port pharo to Cpython, all I did was to create a communication
bridge via sockets and I did that in less that 100 lines of python code.

Its easy , fast and simple. Nothing stops anyone from interfacing pharo
with any popular platform or other language. The fact that people prefer to
stick with pharo frameworks and libraries sends a clear message.

Invest in Pharo , this is what our community is focused on.

[Pharo-users] How to detect wheter the computer is connected to the internet ?

[Dimitris Chloupis]

Hey guys I try to make a way to detect whether my project is up to date and
if not to update it from the github repo automagically. This part works
fine , but I will also like to first detect whether the computer has an
internet connection so to avoid unnecessary errors and checks .

Is that possible ?

You should try to contact github, not google, since that's what you care
about. After all github can be down sometimes so it would fail even with
internet connection.

Just try accessing a well know, always available host with a short timeout ?

[ ZnClient new beOneShot; timeout: 2; get: 'http://www.google.com'; isSuccess ] 
on: Error do: [ false ]
