[Pharo-users] Re: Can a class be not equal to itself?

[Benoit St-Jean via Pharo-users]

It never occurred to me that it would ever be the case!

I've always thought classes were singleton and that SomeClass copy would 
always return the sole instance of that class!


I wonder what are the implications of returning a copy, say, when you 
add an instVar to the "original" class ?  What happens to the reshaping 
of the instances created by the copy?

I guess I have to re-ask again since nobody answered my question from 
this week...


Where can we post Pharo 
questions/remarks/thoughts/you-might-want-to-have-a-look-at-this-cool-idea/whatever 
(or anything that could be of any interest to Pharoers) ?


MAYBE we need another list...

This is getting ridiculous!  The guy spends energy, time, effort and is 
able to gather 13K in prizes and puts Pharo to the forefront with this 
cool contest in schools, makes a lot of youngsters learn & use Pharo for 
their projects, puts up a website, makes videos, writes blog posts, 
PROMOTES Pharo and he gets slapped for posting here ?!?!  WTF ???


Where should he post?  Where should I post ?

Smalltalk didn't "fail". We just didn't have the CPU power at the time 
to achieve our dreams! And "Smalltalk is slow" was tagged forever 
besides the name...

avoid you "later" being surprised if it differs from ST-80.
A marketing strategy analogous to a "fail early" programming paradigm,
and avoid such arguments that try to shackle Pharo.

In practice, its probably many years before Pharo is any more
incompatible with Smalltalk than the incompatibilities between
existing Smalltalks.
But Smalltalk-backward-compatibility should not be one of your
tick-boxes to choose Pharo.

Some rough & simple ideas...

1) Make Pharo visible on Rosetta.org <http://Rosetta.org>

There is currently 1006 tasks (mini projects) implemented in 764 
programming languages. Pharo is nowhere to be seen there, besides 
the programming language entry on the wiki for Pharo still points 
to pharo-project.org <http://pharo-project.org>. This project has 
the advantage of exposing programming languages with small 
tasks/problems any newbie can work on.  You always have the option 
to compare how it's done in your favorite language with the one 
you're trying to learn. Rosetta.org <http://Rosetta.org> is often a 
useful and popular source for people wanting to learn a new 
programming language by starting with some simple problems.

This podcast has a big audience and lots of loyal followers. Anyone 
can create a podcast and upload it there for broadcast. Normally, 
99% the podcasts are related to computer science, programming and 
technology.  It is a well-known and respected podcast as they have 
already created over 3000 podcasts already (it's a daily podcast)! 
They are very flexible on what you can talk about and pretty lax on 
the format : as long as you talk about something you love and that

be easy and quick!

The Computer Language Benchmark Game is another good place to get

Re: [Pharo-users] Large Image Generator

[Benoit St-Jean via Pharo-users]

--- Begin Message ---

Pablo,

Here's my quick list of ideas to generate gigantic images...

The easiest way to fill the image quickly is to load huge packages that 
can also generate tons of data. The firsts that come to mind are Moose, 
Roassal, Seaside, BioSmalltalk, PolyMath, Marea, Magma (not sure if it 
is still supported though) and Dr. Geo. Another possibility is to use 
tools that can import tons of data into the image : there are tons of 
stress-test-gicantic XML schemas out there that we could load/read with 
one of our XML readers out there.


Another good candidate to torture the GC would be the FHCP challenge: 
they had to solved gigantic graphs and, luckily for us, the winners in 
2016 were from Inria so someone there must have the data to load those 
graphs (and perhaps the algorithms!). DeepTraverser could probably do 
the job here.


Other obvious tests involve pushing the language/VM to its limits : how 
does Pharo react if we flood the image with 4 million symbols??? Or 
create a hierarchy of 3 classes? Or have a package with 2000 tags? 
Is there any limit to the size of a methods (say, we create a method 
with 5000 literals)? Or create a gazillion classes, each with the 
maximum number of instance variables possible? What if we create a class 
that has a reference to every class in the image and see how the 
dependency checker copes with that?


Also, there's a lot of objects that are treated "specially" in the 
image.?? How does the VM/GC reacts when there's a gazillion of them? 
Semaphores, blocks, symbols, points, processes, weak objects, etc.


We could also generate a humongous graph/collection/whatever that could 
be loaded fast with Fuel instead of having to create those objects from 
scratch every time.


P.S. I have found quite a few discussions on the Squeak & Pharo mailing 
lists regarding problems with large images and I've collected the 
references to those threads. I'd be more than happy to share those with 
you in private if you're interested! I've also found lots of references 
to GC benchmarks/torture-tests used by other languages with GC and I 
think lots of them could also apply to our memory model...

The main goal of the project is to start a recollection of existing
solutions and to add new ones to generate this synthetic images. We
want also to generate images that reproduce the nature of images. For
example, it is not enough to generate random method selectors if we
are testing the indexing of them. A good index varies its performance
depending of the nature of the text. We need to generate random
methods following some rules a developer whould use, for example using
more a given word or using real words.

Then I have a question... and I'm not being sarcastic here!

As Pharo users, are we allowed to suggest ideas from other environments, 
even other languages or projects?


If I think we should implement something similar to VisualWork's 
MemoryPolicy in Pharo, where should I discuss that?


If I see package XYZ in Python that I think would be worth porting to 
Pharo, where should I discuss that?


If there are features in the Atom editor that are worth considering & 
cool for Pharo, where should I discuss that?


If I have ideas/places/means to promote Pharo or give it exposure, where 
should I discuss that?


If VisualAge has a nice config map to interface MQSeries and I'd like to 
know if a port to Pharo would interest anyone, where should I discuss that?


If I want to know if there's any interest to develop a native DB2 
database driver, should I discuss it here ?  From what I've read, the 
answer is NO.  Do you really think that if I post "hey guys, we should 
really port that to Pharo" on comp.databases.ibm-db2, it will draw any 
attention from Pharoers ? This is getting ridiculous!


I mean, are we limited to only discuss about what's in the Pharo image? 
Yeah, the Collection hierarchy is cool but are we gonna talk about that 
for the next 5 years? As a Pharo USER, I am not limited to what's in the 
image : Pharo interfaces with lots of things on the outside.  If we 
can't discuss about what's outside of the image and that could improve 
Pharo (library-wise),  tell me where I can do so!


If I understand correctly, we can't talk about anything that is not 100% 
Pharo on pharo-dev, pharo-users and lse-pharo4pharo, is that it ?!?!?!? 
What's left for the "outside world" ?


P.S. I'm not saying that this mailing list should be a catch-all place 
where we can discuss about baseball, fishing, cars, music, chess, C# and 
politics.  There has to be a way to sometimes discuss about stuff that 
is "outside" of Pharo but that could help us improve it!

Here we go again...



What is wrong with you people? Seriously? With this "Pharo is NOT 
Smalltalk" BS? If it looks like a duck, swims like a duck, and quacks 
like a duck, then it probably is a duck!


To convince yourself, I urge you all to try to evaluate this in any 
other Smalltalk (Dolphin, Cuis, VisualWorks, LittleSmalltalk, 
ObjectStudio, VisualAge Smalltalk, IBM Smalltalk, Instantiations 
Smalltalk, Smalltalk/X, ObjectWorks, Visual Smalltalk Enterprise, 
Smalltalk Express, Amber Smalltalk, Redline Smalltalk, Smalltalk MT, GNU 
Smalltalk, you-f*cking-name-it-Smalltalk) to see if it compiles:


Transcript inspect.
Workspace inspect.
Processor inspect.
Smalltalk inspect.
true inspect.
false inspect.
thisContext inspect.
nil inspect.
self inspect.
super inspect.
Undeclared inspect.
#someSymbol inspect.
#(1 2 3) inspect.
Object allInstances.
OrderedCollection class inspect.
Behavior inspect.
Class inspect.
MethodDictionary inspect.
Smalltalk garbageCollect.
3@4 inspect.
([ :a :b | a + b ] value: 3 value: 4) inspect.
[50 factorial] forkAt: Processor userBackgroundPriority.


Now, if you still think that Pharo is NOT Smalltalk, I strongly suggest 
we remove all the code that was inherited from Squeak (Smalltalk) or 
inspired/borrowed by/from VisualWorks & others.  Same thing for the VM : 
we should build our own from scratch as Squeak and Cuis also use the 
same!  And we should assign different numbers to every primitive we do 
share with all other Smalltalks out there since 1980 : we wouldn't want 
to be associated with any Smalltalk, right? We don't want any Smalltalk 
in Pharo, don't we, since it is NOT Smalltalk?


Besides, just so you can glady remove all traces of the "forbidden" word 
or heritage, you must know that the current Pharo 8 images has 1724 
references to the global Smalltalk.  If you dig a little bit deeper 
(adding comments, deprecated code, the string 'Smalltalk' as well as the 
#Smalltalk symbol, you'll end up with 5000+ occurrences of the 
"forbidden word" "Smalltalk" in the current Pharo 8 image.  Wanna add 
occurrences of "Smalltalk" in method names as well while we're at it? ;) 
But hey, Pharo is NOT Smalltalk, right? ;)  loll


Should I create a PR for every occurrence of the forbidden word so we 
can get rid of that shameful heritage and clean up the image?  We should 
also remove the strings Squeak (56 times), Cuis, VisualWorks, VW, 
VisualAge & others since Pharo is NOT Smalltalk?  Did I say it enough?  
Pharo is NOT Smalltalk!  Even if I can load Smalltalk code from 
SmalltalkHub, SqueakSource and ss3.gemtalksystems.com, Pharo is NOT 
Smalltalk, do you get it? I can load mcz packages made for Cuis & Squeak 
but, nonetheless, Pharo is NOT Smalltalk!  How many times do I have to 
say it?


Imagine the following discussion:

A- I heard you bought a new car?

B- No I bought a Toyota Corolla.

A- So you bought a new car!

B- A TOYOTA COROLLA IS **NOT** A CAR.

Ain't that discussion & deny stupid enough?

I get the impression we constantly have this kind of denial/discussion 
here...  A serious case of SSS : Shame of Smalltalk Syndrome.


Pharo wants to be different : okay.  Fine. Cool!

But please, stop saying that Pharo is NOT Smalltalk.

It is.

Re: [Pharo-users] [ANN] Hashtable on pharo-contributions

Cool!

If that helps, I'm currently working on a "custom" type of collection 
used for sampling objects based on probabilities. Should be ready in a 
few days if anyone's interested. For lack of a better word, it's 
currently called "SamplingSet". To make a long story short, I'm using 
this to generate random data that mimics the statistical properties of 
those objects in the real world. For example, if I'm generating last 
names for say an instance of class Person for Russia, chances are you 
should very rarely get any "St-Jean" as opposed to "Ivanov" so this 
collection samples those last names accordingly based on their 
probabilities. So all that SamplingSet does is return a random object 
that respects the statistical probability of such an occurrence.


I'm working on a few optimizations as I'm having to deal with sets of a 
few million items and right now, the 4M mark seems to be hard to break 
without paying a high price.  But I should be done withing a week or so.

Hi!

In Moose there is a project call "Hashtable". The goal of this project
is to provide faster collections when they have a big number of
elements.

I think this is something that can be useful for more than just Moose
so I extracted it to pharo-contributions so that we can use it and
improve it more.

Thanks for your quick & detailed answer Pablo!

I have a big list of ideas, all I need to do now is to type my notes! I 
wasn't sure if you wanted to test performance of a specific part/aspect 
of Pharo/VM hence my question to clarify all that!


Is there any preferred image (8.x or 9.x) you're looking for? Do you 
need/want tests that might only apply to P8 or your starting point is 
P9? Are you considering tests that use Morph/UI objects as well?


P.S. I just installed the latest Pharo Launcher and it rocks (long story 
short, don't ask, I had tons of problems previously because of the 
accentuated "i" in my first name, stuff that hadn't been removed when I 
uninstalled, etc. and I'm on Sh*tdows 10 !) so I'll first start by 
moving all my stuff into ONE place (Thanks Pharo Launcher) and after 
that experiment a little bit with Iceberg! In the meantime, would you 
consider contributions in the form of a fileOut/mcz file ?

Hi Benoit,
  the main idea as always is to have better tests.
We have seen that Pharo, and many users reported, that Pharo does not
behaves correctly in some cases when handling large images. When I
take about large images, I am talking about images with a lot of code
and/or with a lot of data (yes the code for us is data... but I am
just differencing because if we are testing senders / implementors we
don't care about having a 10GB ByteArray).

Also we have seen that for correctly testing this scenarios, we need
good images, because depending the characteristics of the image it
stress different parts of the system. As you correctly said we need to
improve the tools (Calypso, System Navigation, Spotter, Iceberg, etc)
and the infrastructure (GC, Compiler, VM in general). So we need to
generate a lot of different images with different characteristics.

Also, as you correctly mentioned we need to generate images with
static behavior and with dynamic behavior (e.g., lots of concurrent
processes).

The main goal of the project is to start a recollection of existing
solutions and to add new ones to generate this synthetic images. We
want also to generate images that reproduce the nature of images. For
example, it is not enough to generate random method selectors if we
are testing the indexing of them. A good index varies its performance
depending of the nature of the text. We need to generate random
methods following some rules a developer whould use, for example using
more a given word or using real words.

So basically, we started collecting the easy algorithms to generate
and we will add more, and of course, it is open to contribution from
anyone and to different usage scenarios. The two I have implemented
are the ones we are using this week to solve three issues: (1)
improving the startup time, (2) improving the detection of deprecated
methods, (3) improving the analysis of big literal methods. I have
finished 1, the other two we are in working.

Also, I will like to add an implementation of the work of Clement and
Sophie to generate images to stress the GC.

If you have ideas or things to add let's share them!!

Cheers,
Pablo

Re: [Pharo-users] [pharo-project/pharo] Proposed improvement : performance of #atRandom: in class Bag (#5392)

[Benoit St-Jean via Pharo-users]

--- Begin Message ---
While I'm at it, another improvement would be to buffer #newFrom: by 
reading large chunks of the argument  via a ReadStream, 
adding the objects read to a  buffer and inserting into the 
receiver via #add:withOccurrences:.  That way, if you read say 1000 
object (of which lots are similar), you don't have to "add" 1000 items, 
you could reduce the number of adds by reducing the duplicates with this 
buffer bag.  Wouldn't make much of a difference in the worst case 
scenario but one can assume that since you're using a bag, you normally 
expect a lot of dups!  So we could gain a lot that way.  Anyway, that's 
what I'm seeing with my experiments (millions of objects) and I'm still 
contemplating that improvement with more & more tests (such as adjusting 
the buffer size).  So far, this is really promising!

The final expression is not needed, since you started with an emptyCheck.

Reformatted then:

|Bag>>#atRandom: aGenerator "Answer a random element of the receiver. 
Uses aGenerator which should be kept by the user in a variable and 
used every time. Use this instead of #atRandom for better uniformity 
of random numbers because only you use the generator. Causes an error

aGenerator nextInt: self size. index := 0. self doWithOccurrences: [ 
:key :count | index := index + count. rand <= index ifTrue: [ ^ key ] ] |


Still, we need a PR as well. And maybe a specific test unless this is 
already covered by other tests.

Re: [Pharo-users] how to get out of this mess

[Benoit St-Jean via Pharo-users]

Hi Roelof,


I probably missed your prior posts but I do have a few questions and/or 
comments for you before I can be of any help!


This code is for tournaments of what sport exactly?  Hockey teams?  
Baseball teams?  Or tournaments between players (such as in chess where 
the concept of Team exists only every 4 years for the chess Olympiads).  
Do you plan on handling different sports? Different tournament formats 
(round robin, ladder, etc).


The whole thing seems to be centered around games/match results but you 
don't have such a class in your example.  Besides, how do you handle 
different results for one team for the same tournament a few years apart 
(say, the 2017 Formula 1 season vs the 2018 Formula 1 season) ?  
Shouldn't tournaments also have a name and a year (or a Season object) 
like they have in tennis, golf, chess, hockey, baseball, etc?


So my first impression is that you need the following classes : Team, 
GameResult, Tournament and something like TournamendDirector to create 
tournaments and create matches (or read/write them).


In other words, we need more info on what you are trying to do!

Dominique Dartois

Thanks for reporting this. This is most definitely a bug, I can confirm its 
occurrence.

I'm CC pharo-dev as this is quite important. This will be a long mail.


This is one manifestation of a problem that has been present for quite a while.

I'll start by describing what I did, what went well and where/how this fails, 
some generic points, and two conceptual solutions (that need further 
verification).

Like you, I created a new subclass:

Object subclass: #ClasseFrançaise
instanceVariableNames: ''
classVariableNames: ''
package: '_UnpackagedPackage'

With comment:

I am ClasseFrançaise.

Try:

ClasseFrançaise new élève.
ClasseFrançaise new euro.

And two methods (in the 'test' protocol):

élève
^ 'élève'

euro
^ '€'

I added the euro sign (because that is encoded in UTF-8 with 3 bytes, not 2 
like ç).
Like you said, the system can cope with such class and method names and seems 
to function fine.

Looking at the .changes file, the correct source code was appended:

SNAPSHOT2019-01-26T23:36:18.548555+01:00 work.image priorSource: 339848!

Object subclass: #ClasseFrançaise
 instanceVariableNames: ''
 classVariableNames: ''
 package: '_UnpackagedPackage'!
!ClasseFrançaise commentStamp: 'SvenVanCaekenberghe 1/27/2019 12:25' prior: 0!
I am ClasseFrançaise.!
!ClasseFrançaise methodsFor: 'test' stamp: 'SvenVanCaekenberghe 1/27/2019 
12:26'!
élève
 ^ 'élève'! !
!ClasseFrançaise commentStamp: 'SvenVanCaekenberghe 1/27/2019 12:27' prior: 
33898360!
I am ClasseFrançaise.

Try:

 ClasseFrançaise new élève.
 ClasseFrançaise new euro.
!
!ClasseFrançaise methodsFor: 'test' stamp: 'SvenVanCaekenberghe 1/27/2019 
12:27'!
euro
^ '€'! !


Doing a file out (or otherwise saving the source code) fails. The reason is an 
incorrect manipulation of this source file while looking for what is called the 
method preamble, in SourcFileArray>>#getPreambleFrom:at: position

An programmatic way to invoke the same error is by doing

(ClasseFrançaise>>#élève) timeStamp.
(ClasseFrançaise>>#élève) author.

Both fail with the same error.


The source code of methods is (currently) stored in a .sources or .changes 
file. CompiledMethods know their source pointer, an offset in one of these 
files. Right before the place where the source starts is a preamble that 
contains some meta information (including the author and timestamp). To access 
that preamble, the source code pointer is moved backwards to the beginning of 
the preamble (which begins and ends with a !).


The current approach fails in the presence of non-ASCII characters. More 
specifically because of a mixup between the concept of byte position and 
character position when using UTF-8, a variable length encoding (both the 
.changes and the .sources are UTF-8 encoded).

For example, consider

'à partir de 10 €' size. "16"
'à partir de 10 €' utf8Encoded size. "19"

So although the string contains 16 characters, it is encoded as 19 bytes, à 
using 2 bytes and € using 3 bytes. In general, moving backwards or forwards in 
UTF-8 encoded bytes cannot be done without understanding UTF-8 itself.

ZnUTF8Encoder can do both (moving forward is #nextFromStream: while moving 
backwards is #backOnStream:). However, ZnUTF8Encoder is also strict: it will 
signal an error when forced to operate in between encoded characters, which is 
what happens here.

It is thus not possible to move to arbitrary bytes positions and assume/hope to 
always arrive on the correct character boundaries and it is also wrong to take 
the difference between two byte positions as the count of characters present 
(since their encoding is of variable length).

SourcFileArray>>#getPreambleFrom:at: is doing both of these wrong (but gets

Re: [Pharo-users] Class name with diacritic character and Pharo

[Benoit St-Jean via Pharo-users]

While we're at it, a similar problem arises when the author name (in my 
case BenoîtStJean) contains a French diacritic.


Just tested it with Pharo 7 (64 bit on Windows 10)...

Fileout works fine.  But filing in crashes!

Thanks for reporting this. This is most definitely a bug, I can confirm its 
occurrence.

I'm CC pharo-dev as this is quite important. This will be a long mail.


This is one manifestation of a problem that has been present for quite a while.

I'll start by describing what I did, what went well and where/how this fails, 
some generic points, and two conceptual solutions (that need further 
verification).

Like you, I created a new subclass:

Object subclass: #ClasseFrançaise
instanceVariableNames: ''
classVariableNames: ''
package: '_UnpackagedPackage'

With comment:

I am ClasseFrançaise.

Try:

ClasseFrançaise new élève.
ClasseFrançaise new euro.

And two methods (in the 'test' protocol):

élève
^ 'élève'

euro
^ '€'

I added the euro sign (because that is encoded in UTF-8 with 3 bytes, not 2 
like ç).
Like you said, the system can cope with such class and method names and seems 
to function fine.

Looking at the .changes file, the correct source code was appended:

SNAPSHOT2019-01-26T23:36:18.548555+01:00 work.image priorSource: 339848!

Object subclass: #ClasseFrançaise
 instanceVariableNames: ''
 classVariableNames: ''
 package: '_UnpackagedPackage'!
!ClasseFrançaise commentStamp: 'SvenVanCaekenberghe 1/27/2019 12:25' prior: 0!
I am ClasseFrançaise.!
!ClasseFrançaise methodsFor: 'test' stamp: 'SvenVanCaekenberghe 1/27/2019 
12:26'!
élève
 ^ 'élève'! !
!ClasseFrançaise commentStamp: 'SvenVanCaekenberghe 1/27/2019 12:27' prior: 
33898360!
I am ClasseFrançaise.

Try:

 ClasseFrançaise new élève.
 ClasseFrançaise new euro.
!
!ClasseFrançaise methodsFor: 'test' stamp: 'SvenVanCaekenberghe 1/27/2019 
12:27'!
euro
^ '€'! !


Doing a file out (or otherwise saving the source code) fails. The reason is an 
incorrect manipulation of this source file while looking for what is called the 
method preamble, in SourcFileArray>>#getPreambleFrom:at: position

An programmatic way to invoke the same error is by doing

(ClasseFrançaise>>#élève) timeStamp.
(ClasseFrançaise>>#élève) author.

Both fail with the same error.


The source code of methods is (currently) stored in a .sources or .changes 
file. CompiledMethods know their source pointer, an offset in one of these 
files. Right before the place where the source starts is a preamble that 
contains some meta information (including the author and timestamp). To access 
that preamble, the source code pointer is moved backwards to the beginning of 
the preamble (which begins and ends with a !).


The current approach fails in the presence of non-ASCII characters. More 
specifically because of a mixup between the concept of byte position and 
character position when using UTF-8, a variable length encoding (both the 
.changes and the .sources are UTF-8 encoded).

For example, consider

'à partir de 10 €' size. "16"
'à partir de 10 €' utf8Encoded size. "19"

So although the string contains 16 characters, it is encoded as 19 bytes, à 
using 2 bytes and € using 3 bytes. In general, moving backwards or forwards in 
UTF-8 encoded bytes cannot be done without understanding UTF-8 itself.

ZnUTF8Encoder can do both (moving forward is #nextFromStream: while moving 
backwards is #backOnStream:). However, ZnUTF8Encoder is also strict: it will 
signal an error when forced to operate in between encoded characters, which is 
what happens here.

It is thus not possible to move to arbitrary bytes positions and assume/hope to 
always arrive on the correct character boundaries and it is also wrong to take 
the difference between two byte positions as the count of characters present 
(since their encoding is of variable length).

SourcFileArray>>#getPreambleFrom:at: is doing both of these wrong (but gets 
away with it in 99.99% of all cases since very few people name their classes like 
that).

There are two solutions: operate mostly on the byte level or operate correctly 
on the character level. Here are two conceptual solutions (you must execute 
either solution 1 or 2, not both), with two different inputs.


src := '!ClasseFrançaise methodsFor: ''test'' stamp: ''SvenVanCaekenberghe

Petr,

Since you seem to want to add this (these) extra instance variable(s) in 
the context of some kind of persistence (objects being retrieved/created 
from/to some kind of database), perhaps subclassing all your objects 
from a PersistentObject class (that inherits from Object) would be the 
simplest solution.

Hi Alistair!

First off, thanks for the "thank you note" in this email & on GitHub.

Would you be interested in working on a port of GeoSphere 
(https://cran.r-project.org/web/packages/geosphere/geosphere.pdf) to 
Pharo ?  I'll have some spare time in the next weeks so we could work on 
that together.  Since this package is widely known and used, it could 
serve as a base for a Geo package for Pharo.  I have R installed with 
this package here so cross-checking Pharo results vs R calculations 
wouldn't be a problem!  That also means plenty of unit tests are 
possible !  ;)


I noticed (at least on Pharo 6.1) that you reference "WebBrowser" which 
is either present in P7 (and not in P6) or it indicates a dependency 
problem.


I also noticed that you use the WGS84 reference ellipsoid as a hardcoded 
constant (in other works, assuming the earth radius is 6378137 meters 
for all calculations).  Modifying the code to have reference ellipsoids 
objects and use the WGS84 as the default (which is what everyone uses) 
would be a more flexible solution. Besides, it would also allow funky 
stuff like being able to use the same framework to work for every known 
spatial body like say, the Moon or Mars or whatever! Besides, that way 
(using reference ellipsoid objects), older maps/coordinates/calculations 
could still be used just by changing the ellipsoid reference.


Let me know if you're interested!

P.S.  I couldn't find a similar package/framework for 
Pharo/Squeak/WhateverSmalltalk.  If I missed it, let me know guys!!  I'm 
not a big fan of reinventing the wheel!!

Hi All,

If anyone is interested, I've created the beginnings of a library for
handling coordinates at: https://github.com/akgrant43/GeoSphere

It only:

- Parses string coordinates
- Calculates the distance between coordinates
- Opens a web browser in OpenStreetMap at the receiver's coordinates

Examples of string formats that can be parsed:

- 144.61025 @ -38.28697
- 38° 17′ 13.09″ S, 144° 36′ 36.9″ E
- 38 deg 17' 13.09" S, 144 deg 36' 36.9" E
- https://www.openstreetmap.org/#map=18/-38.28697/144.61025

The distance calculation uses haversine (assumes the earth is a
sphere), which is good enough for my needs at the moment.

Thanks again to Sven, Benoit, Pierce and Richard for their input.

Cheers,
Alistair

Right, I'll probably have a go at this a put it up on github.

It looks like you've chosen to model the coordinates using the Point
class rather than creating a Coordinate class.  Can you explain why (I
don't have a strong preference either way, so am wondering what your
thinking is).

It also looks like it is longitude @ latitude.  Is that correct?  (I
guess it lines up with the point y value being vertical, which is
latitude.  But most written forms put latitude first).

Thanks!

If I'm not mistaken (according to the fact that both class comments are exactly

Concerning Day1, part2 of Advent Of Code 2018, here's my quick take (Coded in a 
workspace with Squeak)...

| file total numbers index frequencies duplicate |

duplicate := false.
frequencies := Set new: 15.
frequencies add: 0.
numbers := OrderedCollection new: 1000.
total := 0.

file := StandardFileStream readOnlyFileNamed: 'day.1.input'.
[file atEnd] whileFalse: [numbers add: (Integer readFrom: file nextLine)].
file close.

index := 0.
[duplicate] whileFalse: [index := index \\ (numbers size) + 1.
                        total := total + numbers at: index.
                        (frequencies includes: total) 
                            ifTrue: [duplicate := true]
                            ifFalse: [frequencies add: total]].

^total

Just realized that String>>#asNumber works differently in Pharo and in Squeak.

'+3' asNumber "Works in Squeak, not in Pharo"
BUT

'+3' asInteger "Works in both Squeak and Pharo"

Usually, it's way nicer/better/suggested to declare all variables...  Forgot

Nicer version:

Well, I guess I don't belong here anymore since "Pharo is NOT Smalltalk" as you 
keep saying!  

And since I've been a Smalltalker for only 25+ years, I guess Smalltalk is 
really for me as you wrote!  Every Smalltalker is a moron as you so often imply 
(especially in private emails incidentally): only Pharoers "do it right"...  So 
I'll go back to that moronic programming language!

P.S.  I'll let you handle the questions in #pharo on IRC as I'll no longer be 
on the channel : you'll see, it'll be really instructive for you! People there 
have those weird practical problems, it's crazy!

Re: [Pharo-users] Where do we go now ?

[Benoit St-Jean via Pharo-users]

--- Begin Message ---
I concur with Sean's comments.  The problem is not using names : the problem is 
for new users.

A very quick look at what's in Pharo 7 shows the following names : Iceberg, 
Ombu, Calypso, Flashback, Nautilus, Renraku, Zodiac, Shift, Zinc, Hermes, 
Beacon, Cargo, Hermes, Opal, Shoreline, Epicea, Balloon, BlueInk, Commander, 
Fuel, Glamorous, Glamour, Gofer, Hiedra, Metacello, Moose, Ring, Rubric, Shout, 
Spec, etc...

How many Pharo *users* (not regular contributors!) know what those 
tools/frameworks/packages do ???  Make the test and tell us how many out of 30 
names you were able to identify correctly !

Unless we *clearly* publicize/describe what those names are, there's no way in 
a thousand years you could tell that BlueInk is not a package dealing with 
fonts (that was my first guess) !
Newcomers and (developers in general) expect a few things.  For instance, 
there's a gazillion UI frameworks out there and, most of the time, the name 
used for them is one of a famous painter.  VisualWorks had Chagall for 
instance. 

Or you'd expect some kind of hint from the name, e.g. XStreams, ScriptManager, 
RefactoringBrowser.

Or somethings as simple as Regex, the regex package from Bykov.  Or 
Announcements from the same guy.

Or names that reveals something from an etymology standpoint, e.g. TelePharo.

The simple fact that someone had to create a file to describe all those 
names/projects/framework on GitHub tells us a lot 
(https://github.com/AdamSadovsky/pharo-family/blob/master/catalog.txt) !

Unless we make it *EXTRA* clear and easily searchable and obvious what those 
names represent, it's just more confusion for the newcomer. 

Do you know what Celery is?  Probably not!  But if I ask you the same question 
for RabbitMQ, ActiveMQ, MQSeries, StormMQ, SnakeMQ, IronMQ, ZeroMQ, MQTT and 
MSMQ, you probably figured out it's related to message queues, right?  Well, 
Celery is also related to message queues...  See?

There's nothing worse or more confusing than a bad/weird/unrelated name.  For 
example, the biggest company in Canada is called "Canadian Tire".  If you think 
you're gonna end up in a place specialized in tires, you're off for a big 
surprise 

On the other end of the spectrum, you have something like iTunes.  Everybody 
knows iTunes.  And I guess, even if you didn't know, you can kinda easily guess 
it's related to music.  Your grandma might not exactly remember the name but 
she'll remember "Was it xTunes? zTunes? yTunes? It was something 'tunes', to 
music" !

And comparing other "names" with Pharo names makes no sense.  Nike, Hibernate, 
Jenkins, Docker and Oracle cannot be compared to Epicea, BlueInk, Flashback and 
Opal.  They just don't have the same visibility and public exposure.  That is 
hopefully a problem that will vanish as Pharo gets more and more attention and 
users and gets known more and more.  But in the meantime, those names merely 
help us differentiate implementations of solutions, for us the *regulars*.

Was it really that hard to replace the old workspace with Workspace2 or 
WhateverWorkspace ?  Or even better : get rid of the old Workspace and replace 
it with Playground while retaining the name "Workspace" ??? Did we really need 
to call it Playground and confuse every new Smalltalker out there that has seen 
the term "Workspace" for Dolphin, Smalltalk/X, VisualAge, VisualWorks, 
ObjectStudio, GNU Smalltalk, Amber, PharoJS, Smalltalk MT and every other 
Smalltalk around *EXCEPT* Pharo?

Why are we trying to complicate things when we could just make it 
soo simple?

Let's make it easy for **newcomers** to get their way around and know what the 
named tools/frameworks do.  Get rid of duplicate tools (do we need more than 
one kind of Inspector?  Do we need 2 compilers?  Do we need 8 Delay schedulers? 
 Do we need 2 system browsers? Do we need the duo Workspace/Playground) ?  Make 
these extra tools available somewhere it can be loaded from if a user *really* 
wants them in their image, but let's keep those OUT of the image!

IHMO this is certainly a positive subject because it highlights the
as-yet-to-be-resolved tension regarding understandability of the system
between having a unique name (good for googling, distinguishing between
versions) and a name that reveals what the project does/is for. What is the

[Pharo-users] UTF-8 encoding

[Benoit St-Jean via Pharo-users]

--- Begin Message ---
Regarding the problems I have with my firstname and file paths and utf-8 
encoding, I found something weird in the UTF-8 encoding.  In fact, to be more 
precise, I found something strange when converting a String to a ByteArray 
(which UTF-8 encoders convert from)
If I look at the example in the comment of ByteArray>>utf8Decoded, 'Les élèves 
français' is encoded as: 

#[76 101 115 32 195 169 108 195 168 118 101 115 32 102 114 97 110 195 167 97 
105 115]

NOW, if I take that very same string, 'Les élèves français' , and convert it to 
a ByteArray, I get :
'Les élèves français' asByteArray printString.

#[76 101 115 32 233 108 232 118 101 115 32 102 114 97 110 231 97 105 115]

The 2 don't match!
By the way, this problem exists on Pharo 5.1, 6.1 and 7.1 (on Windows 10 )
Can anyone confirm/infirm on another platform to see if this is 
Windows-specific?

"Float randomBetween: -4.1 and: 2.5

I also prefer #randomBetween:and: .
"Going to the class side of Float makes sense because you create a new 
instance."

But I'm not so sure about putting this on the class side.
In fact, right now #atRandom is on the instance side and it's been that way 
since the beginning.  It would be akward to have one method of generating 
random numbers on the class side and all others on the instance side.  And 
moving everything on the class side would break tons of code and legacy code.  
Besides, random numbers have always been seen and/or dealt with as streams : 
the intent was to get "the next one" in the stream, not create "a new instance"

Install using the MSI, the laucher should go into %APPDATA% and images/vms to

This is the observed behavior of that new version.

Tried it, doesn't work.
Changing the .js file didn't change anything.  The problem occurs in the 
image...

Problem seems to be (in my case)
1) the accentuated "Î" which cannot be handled properly in a path FileReference 
(expecting UTF-8 encoding but the string is seen as a Latin-1
2) PlatformResolver>>launcherUserFilesLocation that defaults to my "Documents" 
folder, namely "C:\Users\Benoît St-Jean\Documents", hence the path string 
encoding problem

 Install the bleeding edge thing, it works for me on win 10. 
I also noticed that the launcher runs images with VMs that do have a weird 
management of cursors in the dark themes, it seems that there the masks are not 
used properly and so, the dark arrow has no white border making it impossible 
to see.It was not like that before, so I suspect a VM thing.

Thanks for those.  I don't much time right to devote, but managed to knock one 
off.And I learn't something new. I'd not known there was a setting for screen 
background.
The other ones seem related to a problem dealing with user home folders 
containing non-ascii characters.Currently this seems only to affect a small 
number of people, but is a show stopper for them,and the numbers will grow with 
our hoped for growing popularity.
As a work around, in the PharoLauncher settings can you set the directories 
like C:\PharoLauncher\imagesC:\PharoLaucnher\vmsand report if that helps.  
Note, I bumped into an issue changing that setting myself recently where it 
tries to migrate the existing images from the old to the new folder, causing a 
catch-22 when your tryingto do that to work around other problems.  To work 
around that, I had to scroll down the debug stack to find where the migration 
was iterating through the image folders,and short circuit that with "Return 
entered value" from the context menu.  Any valuewill do when the return value 
is not used. good luck.
@PharoLauncher maintainers, can the change in this setting be made to succeed 
even if the migration fails.(I need to run right now)

"You cannot take an alpha version and expect production quality."
I'm on Windows 10, using Pharo 7.0 alpha 32 bit.

Can I at least expect to be able to save code in my local Monticello repository 
? It bombs. I just reported a bug!
Can I expect the Windows installer for Pharo Launcher to work on Windows?  It 
doesn't : it crashes.  

Can I expect Pharo Launcher (not installed from the .exe installer) to work on 
Windows?  It just doesn't. I get all kinds of error related to WindowsStore, 
bad UTF-8 encoding and other things... (see 
https://twitter.com/smalltalkdev/status/978973863332798464)
Can I expect that when looking for implementors of a method things still work?  
I get duplicates (see attached file).
Can I expect reading input from the console to work on Windows?  It doesn't.
Can I expect to be able to test my stuff on Windows?  That's kinda hard when 
Windows is always 6 months to 1 year behind VM-wise.
Can I expect to be able to contribute ?  That is kinda sad but all the cool 
scripts out there are .sh files.

I'm not whining about the effort people put into this project : I'm mostly 
whining about duplication of effort and code and *very poor* Windows support...
Just spend 2 weeks working with Pharo on Windows.  You can start with version 
5.1 if you want and let me know how it goes...  Brace yourself, I'm telling 
you, you're off for a wild & unpleasant ride.

[Pharo-users] Where do we go now ?

[Benoit St-Jean via Pharo-users]

--- Begin Message ---
Hello guys,

Just a quick word to get some things straight because, quite frankly, I really 
don't know where we're heading.

When Pharo started, the goal was to depart from Squeak and do a *major clean 
up* of all the code, especially Morphic.  The promise of a new, clean & lean 
Smalltalk attracted a lot of people.  And then...

I'm looking at the Pharo 7.0 image right now and I just don't get where we're 
heading.  Every Pharo release gets bigger, and bigger, and bigger.  I don't 
mind the environment getting bigger if it adds functionalities or new tools but 
that's not quite the case here. LOTS of stuff is just duplicated.

Do we really need 2 code completion classes (NECController, NOCController) ?  
Do we really need 2 system browsers (Nautilus, Calypso)? Do we really need 2 
compilers (OpalCompiler, Compiler) ?  Do we really need 8 delay schedulers 
(DelayMicrosecondScheduler, DelayMillisecondScheduler, DelayNullScheduler, 
DelayExperimentalSpinScheduler, DelaySpinScheduler, DelayTicklessScheduler, 
DelayExperimentalCourageousScheduler, DelayExperimentalSemaphoreScheduler) ?  
Do we really need 2 inspectors (GTInspector, EyeInspector) ?  Do we really need 
2 workspaces (GTPlayground, Workspace) ? Et cetera. Et cetera. Et cetera.  I 
could go on, and on, and on...

Pharo 5.1 had 5885 classes. Pharo 6.1 had 6481 classes. Pharo 7.0 alpha has 
7612 classes.  Can you see a trend?

Pharo 5.1 had 416 preference settings. Pharo 6.1 had 494 preference settings. 
Pharo 7.0 alpha has 662 preference settings.  Can you see a trend?

Pharo 5.1 had a 27.44 MB image. Pharo 6.1 had a 35.18 MB image. Pharo 7.0 alpha 
has a 47.97 MB image.  Can you see a trend?

Add to that the fact that Pharo is a nightmare when you want to port code.  
Just with the 7.0 release, 61 classes will be deprecated (and lots more to come 
if you search for the string "deprecated" into the code, most of the time 
hidden in the comments of the soon-to-be-deprecated-in-Pharo-8-I-guess classes).

You have code that deals with sockets, should you use the old Socket classes or 
convert everything to Zodiac? And why do we keep both "frameworks" in the image 
?  Pharo hasn't been backward compatible with "old socket classes" a looong 
time ago anyway!

You have code that deals with dependencies, should you use the old dependents 
mechanism or convert everything to announcements?

UI speaking, what framework should anyone use ?  Athens?  Something else?

You have code that deals with streams, should you use the old stream classes or 
convert everything to Zinc ? And why do we keep both "frameworks" in the image 
?  Pharo hasn't been backward compatible with the old stream classes a 
looong time ago anyway! 

So what's the plan?  For instance, should I keep using the Nautilus Browser or 
I should switch to the Calypso browser and get used to it because Nautilus will 
be deprecated?  Or should I just don't care because a third system browser will 
be added in Pharo 8 just because "it's cool, let's add this one too!" ?

Couldn't we just decide on what's "official" and what's a goodie or an external 
optional tool/package/framework the same way all other Smalltalks do?  If you 
say Calypso is the official & supported browser, fine!  Then just get Nautilus 
out of the image, create a nice loadable package for it and if someone prefers 
Nautilus, they'll just have to load it into the image, the same way VW has a 
gazillion optional tools/packages/frameworks you can load from a parcel!

Whenever I get asked a simple question by a newbie like "Oh, which system 
browser should I use?", quite frankly, I don't know what to answer.  Did we 
include Calypso to deprecate Nautilus later?  Is Calypso just a proof of 
concept?  Is it just an optional tool?  What about all those delay schedulers?  

"I loaded this code from SqueakSource and it just doesn't work".  Should I help 
the guy to fix it or just tell him to convert all the code to the corresponding 
framework in Pharo?

Perhaps a little bit of clarity and details about what's coming and what's the 
plan would be beneficial to a lot of us.

 I do bitshifts and masks on Integer.

What if you want to take the bits from the 3rd to the 7th? You have to
do a some arithmetic to get the slice you want.
I'm simply asking for something more dev-friendlier that adds a
"layer" on top of that, but that internally does regular bitwise.

What I don't like about Integers is that you "lose" information about
the zero bits to the left, and with a ByteArray you don't, because the
array is fixed size.

E.g.
(1 << 16) printStringBase: 16. "'1'"
#[1 0 0] hex "'01'"

Maybe I'm too lazy asking when I could have done it myself :)

a) 2r1010110 "2 to 5 = 2r10[1011]0 = 2r1011 = 11"

or

b) 2r1010110 "2 to 5 = 2r10[1011]0 = 2r00[1011]0 =  2r0010110 =  22"
Both cases can be dealt with bit shifting and a bitAnd with optimal performance.

 Is there any package/library that makes bitwise operations as simple
as with an Integer, but for larger numbers (as in a ByteArray).

Something that allows me to "slice" a sequence of bits, or extract
some using the same protocol as with a String of ones and zeros.

Now when I need to work with sequence of bits, I convert an Integer to
a zero padded version of it up a known size, and then do #copyFrom:to:
to extract what I need and read back the number from it.

I could use a bytearray for it, but as its name implies, it is
oriented towards bytes rather than bits (as in the case of Integer).

Now I do stuff like the following to to extract the first 5 bits of a
fixed length 256 bit array (an Integer).

Integer
  readFrom:
    (((SHA256 hashMessage: message)) asInteger
      printStringBase: 2 length: 256 padded: true)
      copyFrom: 1 to: 5)
  base: 2

I understand bitwise operations, but I couldn't find something that
does the above in a conciser way.

Performance in my case isn't critical, but working with strings is
probably two orders of magnitude slower than manipulating bits in
integers or ByteArrays

Estaban,
I understand the difference between the 2 approaches my point was just to 
mention that I guess there are some advantages to shrink the image (as compared 
to bootstrapping from a minimal image) since all major vendors used that 
approach (and are still using it).  It's just that I was curious to know if 
anyone knows any paper/document/study comparing the 2 approaches or explaining 
in detail both of them.  I googled for a few hours but couldn't find anything...

On a side note, being a long-time VW & VAST user, I've always felt the Image

resulting image.  
I don't recall ready anything substantial comparing the Pharo way 
(bootstrapping from a minimal image and adding stuff) to the VW & VAST way 
(removing unreferenced stuff) but this would definitely be an interesting topic 
to read about.



No idea if any “substantial" thing has been written (there are some phds around 
that may talk about), but main difference is very simple to explain: first 
approach (which was the same for Pharo before) is non-deterministic while the 
second is. Then, for purpose of repeatability of process (and testing, etc.) 
bootstrapping is better. You would not know the amount of effort made to make 
this possible, it required at least 2 phd works and a considerable amount of 
engineering effort.In our community, Pavel is the person that has the bigger 
experience on shrinking process images. I followed his work for years and I 
know the fragility of the process. Basically each new addition/removal was 
breaking it and needing dependency tracking, etc. Now is the opposite: you just 
add what you want, and you are sure the resulting image is a) healthy and b) 
identical when running.

Right, I think changing things now will be quite a bit of work.

However there are a couple of things we can do to make life a bit easier:

1. Add a method that facilitates TZ independent comparisons.
2. Add a bit more information in the class comments.


I've named the method #dmyEquals: below, although I don't particularly
like it.  If anyone has a better idea, please reply.

I've also added some proposed text for the class comments.

If I don't hear back in a couple of days I'll submit a PR (with
automated tests).


Cheers,
Alistair



dmyEquals: aDate
    "Perform a time zone independent comparison of the dates, i.e.
only compare day, month and year"

    ^self year = aDate year and: [
        self monthIndex = aDate monthIndex and:
        [ self dayOfMonth = aDate dayOfMonth ] ]


Class comment:

Instances of Date are Timespans with duration of 1 day.
Their default creation assumes a start of midnight in the local time zone.

!Comparing Dates

We tend to use dates in one of two modes:

- Time zone dependent
- Time zone independent

In the first instance, dates are only the same if they are in the same
time zone (otherwise they are two different 24 hour periods).  This is
the default behaviour of Date.

In the second, comparison is only interested in whether the day, month
and year are the same.

As an example, take someone's birthday.  If I want to know whether we
were born on the same day, I will want to compare dates without time
zones.  If I want to know if it is currently their birthday where they
are, I'll want to use time zones.


[[[language=smalltalk
| birthday1 birthday2 |

birthday1 := (DateAndTime fromString: '2018/01/01T00:00:00+10') asDate.
birthday2 := (DateAndTime fromString: '2018/01/01T00:00:00+01') asDate.

"Is it person 1's birthday now? (where they live: UTC+10)"
birthday1 includes: DateAndTime now.

"Do person 1 and person 2 have the same birthday?"
birthday1 dmyEquals: birthday2.

Hi Glenn,
Another very useful tool you can use to save/manipulate/store Smalltalk scripts 
is ScriptManager (http://catalog.pharo.org/catalog/project/ScriptManager).  
There are plenty of similar tools but this one is very easy to use and simple 
and has been doing the job for years for me.

 Subject: [Pharo-users] Help in thinking about how to save a "program"
   
Hi all.  I’m new to Pharo and loving it.  As I transition from a text-file 
based mindset, I’m a little stuck and would appreciate help in how to think 
about a situation in a Pharonic (Pharo-ish, Pharoc?) way.
I”m crafting a short program to help me process a large text file 
(specifically: extract, sorting, and regularizing the “keyword” fields of a 
large BibTex file). Especially since I don’t really know what I’m doing, 
working in a Playground has been a great development environment.  Now that the 
program is complete (under 30 lines, wonderful), I want to be able to save it 
for future reference (and perhaps for future use).  If I’d written a shell 
script, I’d just save “fixBibDeskKeyWords.sh” to a directory. I’m not sure what 
to do in the Pharo environment, thought.
At the moment, it just lives in the Playground I’ve developed it on.  I could 
save the image and leave that Playground open, but I’m just positive that’s not 
a best practice. I also worry about what happens if I closed/cleared that 
Playground by accident.
I think I understand that, if I created a new package, I could use Monticello 
to save it to a local cache and load it into a new image whenever I needed it.  
But, given that it’s short, highly specialized and fairly linear, the idea of 
creating a “GHBibDeskStuff” package with one class (“GBibDeskKeywordFixer” 
containing a single “FixFile” method seems really heavy and awkward.
Can one save the contents of a Playground in a Pharonic way?  Is there a better 
approach?
Thank you to all involved in this wonderful programming ecosystem. I appreciate 
any advice.

Hey guys , I play with PostgreSQL and I really like it, sorry Esteban :D
I am using Python for it but I would like to give access also to Pharo to my 
database. I was informed that Garage has a driver for PostgreSQL , is there any 
other candidate ? Any advice ?

Tell me which exact package you loaded (or even better, the exact to load it) 
and I will test some code against my PostgreSQL server...

Re: [Pharo-users] [Pharo-dev] What is the craziest bug you ever face

[Benoit St-Jean via Pharo-users]

--- Begin Message ---
My worst bug(s) is(are) related to the TopLink ORM.
In one particular case, we were working on a *huge* system and different 
"modules" were assigned to different teams.  Every module was working perfectly 
by itself (as confirmed by the SUnit testing) but sometimes, the database would 
get out of whack.
I finally realized that depending on the classes you used to perform object 
deletion (we had a parent-children-familymembers kinda model), none of the 
"modules" did it the same way and they all differed when it came to access the 
to-be-deleted object.  Most classes accessed the same "kind" of object from a 
single access point but not all of them!  That did create interesting problems 
where the to-be-deleted object reappeared in the database with old values, or 
just vanished during some operation only to reappear afterwards...  Besides, 
debugging proxies and cached objects is a real pain in the *ss !  And in many 
cases, you can't ever log properly anything as it would instantiate the 
proxies!  So I ended up not trusting the Smalltalk side of things and worked my 
way out from DB/2 logging only!    -

[Pharo-users] Socket, network, testing and coding

[Benoit St-Jean via Pharo-users]

--- Begin Message ---
Hi guys,

Quick question regarding sockets and testing.

I'm trying to implement a simple communication protocol to exchange data 
(strings) between 2 images and I was wondering what was the easiest way to 
test/develop my code?  I want to be able to do something similar to a chat 
client between 2 images where none of those 2 images acts as a server.  So data 
can originate from any of those 2 images and both images have to "listen" to 
each other.  Besides, both images would have to transmit/receive on the same 
port.

1) Is this possible (the way I want to do/test it)?
2) How do I simulate something like this on a *single* machine running those 2 
images?
3) Do I need to have one of those 2 images act as a "server" ?
4) Any helpful tip and/or interesting link to propose?
5) Can you think of any simple code or example I could look at to understand 
what I need to do?  -

It can be useful if you want to save some space in some very specific cases.  
You could have a one million strings 'hello' (hence one million objects) or 
deal transform them into symbols and have only one #hello.  I recall a coworker 
telling me about this ultra-fast string search program in Gemstone where they 
transformed a gazillion duplicate strings into symbols thus using wy 
less memory and speeding up the lookup.

Hi, I know Symbol is subclass of String.Any string object can become 
symbol object by sending 'asSymbol' message..I think  symbol must has its 
meaning in comon use, so the symbol should be composed of alphabet or number 
‘without space“.
BUT There are not compliant below1.    ' ' asSymbol     no 
meaning2.  '$%%&' asSymbol     no meaning3.  'sign' asSymbol = 'sign ' 
asSymbol   >>>  false because of space.3. '  one two  three ' asSymbol

I guess you can circumvent the inlining by using perform (and selecting the

true perform: #ifTrue: with: [ 3 inspect ]

Well, in fact Boolean class has no instances, the boolean value true is an 
instance of True class, you should look at the ifTrue: methods in the 
subclasses of Boolean True and False. 
But also, ifTrue: expressions are inlined, as the comment says in the code you 
posted. So I think that all this ifTrue: methods are never actually executed.
2016-10-31 14:17 GMT+01:00 CodeDmitry :

I am looking at

ifTrue: alternativeBlock
        "If the receiver is false (i.e., the condition is false), then the 
value is
the
        false alternative, which is nil. Otherwise answer the result of 
evaluating
        the argument, alternativeBlock. Create an error notification if the
        receiver is nonBoolean. Execution does not actually reach here because
        the expression is compiled in-line."

        self subclassResponsibility

In order to perform the block, ifTrue must somehow end up evaluating the
block, but this code only sends a subclassResponsibility message to itself
and implicitly returns itself.

Where does the block actually get evaluated?

Subject: Glorp
Hello Pharoers,
I want to use Glorp and I am puzzled as to what to install.
I have found a few Glorp related package and I really don't know which one to 
use nor which one is current.  Besides, those packages are spread across 
different websites.

So, which one should I use? And from where?
My current Pharo 5.0 images has the following in the Pharo Project Catalog :

Glorp? GlorpDBX? Garage?
On a different note, if anyone's interested, I'd be more than happy to 
test/fix/participate/develop for Glorp.  I have had the chance (ahem!?!?!?) to 
develop with TOPLink (Glorp's ancestor) for quite a while so Glorp is somewhat 
familiar to me.  In that case, where's the current effort/version to develop 
Glorp for Pharo and which Pharo version is the preferred one for 
development/tests ?
