@cormas super good news ! A good old #ABM with modern language : #pharo !

@der_kleine_herr_b #Smalltalk nennt es auch inject:

Functional languages often provide a higher-order function called fold or reduce to accumulate a result by applying some binary operator iteratively over all elements of a collection. In #Pharo this is done by Collection» inject:into:

The first argument is an initial value, and the second argument is a two-argument block which is applied to the result this far, and each element in turn.

(1 to: 100) inject: 0 into: [:sum :each | sum + each ]

I have quite a lot more followers than I did when I first wrote my introduction, so it’s only fair that I’m writing a new one, bump up the major version.

Hi! o/

I am Ștefan (ș as sh, I also accept Stephan or the equivalent in your language). I’m 21 years old, ♑, he/him, proud #leftist and soon to graduate CS @ UVABc. Sort of proudly living in #romania. My native language is Romanian, fairly proficient at English, slowly learning #finnish (and #italian).

Tried a lot of programming languages in my childhood up until now, a non-chronological list of ones that stuck with me for one reason or another being: VB6 (that’s what I started on at 8 years old), #pascal (+ #freepascal and #delphi), #perl (+ #raku), #tcl #tcltk, #lisp (usually #scheme, on a good day #elisp #emacslisp and #commonlisp), #elixir, #php, #forth, #lua, #oberon, #modula-2, #cpp #c++, #ocaml, #fsharp, #smalltalk (+ #squeak #pharo #self), #ada, #powershell, #dart, #matlab, #rlang, #zig, #nim, #cobol and #julia. I don’t claim full proficiency in all of these, but I’m familiar enough with these (+ some others not mentioned here) that I could get along just fine with 2 weeks at most of studying and looking through cookbooks and examples). I’m flexible in learning new languages and technologies if needed.

I also do #sudoku and #math for fun (especially functional equations and number theory problems, sometimes calculus and geometric algebra). I am interested in #linguists, #conlangs (#lojban and #esperanto) and #nlp, contemporary (post-‘45, usually post-‘89 for me) history, #balkan history, lower-level stuff (I like to learn about how tools around me work, I’m most interested in #compilers, #emulators and #microcontrollers), #typography and #latex, #linux + #bsd, #msdos, #amiga, #oberon, #plan9, #philosophy, #astronomy (especially in a worldbuilding context) and #philosophy, along with other less notable interests.

I engage in #politics relatively often irl, although I’m not inserting it in absolutely every scenario in my life. As I mentioned, I’m a #leftist and #progressive (or… um… #woke) (Nazis and fascists can have a merry fuck off, DNI with me). I am also a spiritual person, a #deist (if you really want to put it that way, an agnostic, although it’s not quite true) and I find #astrology and #tarot interesting (I’ll let you guess my moon and ascendant, let’s see how close you are).

With that being said, I hope I’m welcome here, you can pick your subset of things that interest you from this list, you have plenty of options. :P Quite a bit longer than last time, but oh well…

@collin If you're running Windows, Dolphin Smalltalk allows you to package your #smalltalk application as a stand-alone executable. I haven't tried it yet, but I believe a package like Cruiser lets you create native Linux or Windows executables using #pharo.

If you want a Ruby-like experience that compiles to an executable on Linux or Windows, have you looked at Crystal? (https://crystal-lang.org/). I haven't taken it for a test-drive in a while, but it's very interesting.

Je serai ce mercredi 28 juin au #Pharo à #Marseille (Université d'Aix-Marseille) pour les rencontres des "sciences de la #durabilité et (in)actions : repenser nos pratiques". Je
parlerai, dans la session de @labos1point5, du #laboratoire d'#astrophysique de Marseille, un laboratoire #spatial (CNES) en transition.

Ces rencontres sont organisées par #FutureEarth. Programme complet ici : https://france.futureearth.org/french-global-hub/les-rencontres-sciences-de-la-durabilite/

@collin I think they might have considered it a failure if it is true that users didn't get into modifying the software they were running. Devs not getting it might not have bothered them as much.

@rahoulb well, you tried 👍🏼

Taking the liberty of including @drgeo , who was bringing his software to #Smalltalk (tried #Pharo, switched to #CuisSmalltalk). i.e. knows a thing or two about developing in Smalltalk.

In object-oriented languages, method visibility modifiers hold a key role in separating internal methods from the public API. Protected visibility modifiers offer a way to hide methods from external objects while authorizing internal use and overriding in subclasses. While present in main statically-typed languages, visibility modifiers are not as common or mature in dynamically-typed languages. In this article, we present ProtDyn, a self-send-based visibility model calculated at compile time for dynamically-typed languages relying on name-mangling and syntactic differentiation of self vs non self sends. We present #Pharo, a ProtDyn implementation of this model that is backwards compatible with existing programs, and its port to Python. Using these implementations we study the performance impact of ProtDyn on the method lookup, in the presence of global lookup caches and polymorphic inline caches. We show that our name mangling and double method registration technique has a very low impact on performance and keeps the benefits from the global lookup cache and polymorphic inline cache. We also show that the memory overhead on a real use case is between 2% and 13% in the worst-case scenario. Protected modifier semantics enforces encapsulation such as private but allow developers to still extend the class in subclasses. ProtDyn offers a VM-agnostic and backwards-compatible design to introduce protected semantics in dynamically-typed languages.

Smalltalk пока что для боевого применения плохо годится.

Squeak/Pharo нестабильны и медлительны, VisualWorks Smalltalk стабилен и быстр, но стоит денег. А Cincom не работает с Россией в свете текущих событий. Есть ещё GNU Smalltalk, но коммерческая разработка вроде как запрещена на нём. Есть американская VisualAge Smalltalk, но она платная и возможно сильно устаревшая. Есть Smalltalk/X - вроде как немецкая разработка, тоже платная и, при этом, пощупать среду разработки бесплатно не дают. Есть Smalltalk MT - но он для разработки игр и под винду.

Может быть, Squeak/Pharo на GraalVM будут быстры и стабильны. Но я не знаю, не щупал.

@Conornash That's interesting!
I did a complete round trip:
Started with Smalltalk/V for MDOS in the late 80s. Used the same #Smalltalk on Windows and OS/2 in the early 90s. Used C++ for the rest of that decade. Then switched to #Python as a substitute for Smalltalk. Used #Squeak and #Pharo for private projects. Finally came back to #Cuis around 2015. After some discussion I started my own Cuis-based Smalltalk called #Haver​.

@Conornash That is why I gave up using #Pharo​.

There are oodles of packages looking useful. Once you want to use one them, you soon discover that exactly this package stopped being useful, because it does not work or even load with newer Pharo versions. (Backward compatibility is for wimps!)

#Cuis is IMHO a much better alternative!

J'ai écrit un nouveau blog post sur comment faire des baselines en #pharo
https://badetitou.fr/misc/2023/05/01/pharo-baselines-in-5mins/

C'est fou comment j'ai procrastiné pour écrire ça. Alors que ça a pris 1h, et que je vais pouvoir rediriger plein de personne vers le post dans le futur... Comment gagner du temps :-)

@nytpu i don't know if i should really like the idea of a special IDE (GUI). E.g. with #pharo Smalltalk it just annoys me that they are always behind the technical development. I have a HDPI display and it is still not supported. The font rendering just looks like crap and annoys me so much that I just don't want to use #smalltalk. But see e.g. #clojure or #visual-studio-code in combination with #calva. I can start a REPL directly for a project and evaluate the code directly in the editor and..

@garrett

to learn coding for a kid your chids age start with ucblogo or the libreoffice-librelogo [ a logo implementation surprising built into libreoffice ] all available from debian i would also recommend a large trackerball thats easy for a childs hand to grasp with an external keyboard with a nice positive click

https://askubuntu.com/questions/689437/logo-programming-language

IF the Dell can take KDE there is Kturtle another logo version

From there i'd recommend #Pharo #Smalltalk or #Racket as they have good built in IDEs & are great languages to learn the "basics/fundementals" of a language + plenty of online material

After that you can go down the #emacs route with Python/Ruby/Scheme which covers popular,OOP or functional

watching the #GlamorousToolkit demos makes me want to implement an #emacs #lisp bytecode VM in #pharo #smalltalk

I think pharo smalltalk is awesome and terrible at the same time. It's like I can't make my own mind up. #pharo

@april but then many advantages of the actual smalltak environment are lost. For example, I had once written a web application in seaside. I found it super ingenious, when an exception occurred, a debugger with the respective place was displayed directly, I could fix the place, and exactly at this point the code could be executed again (Without losing the last state). What I would like to see is a completely web based environment for #pharo smalltalk.
