Fwd: arXiv endorsement request from Kasper Osterbye

by Kasper Osterbye

Cheers all I am trying to get a usable account on arXiv to have a place where I can put some papers on what I am doing as documented experiments. I find arXiv interesting as it will allow me to publish papers. My ambition is to have a place where I can publish them at what I think of as workspace level. For this to work, you need to click on the https://arxiv.org/auth/endorse?x=HNLNOYï¿¼ My first paper is enclosed (the actual thing to read there is the meta-conclusion - page 5).

Hi Stephane, since I know people are already making their travel and accomodation plans: * can you clarify when the actual conference starts and ends - Monday or Tuesday? * is the venue already fixed (faculty of informatics or main campus)? These are the two most important questions for now;-) Joachim Am 20.02.26 um 12:12 schrieb stephane ducasse via Pharo-users: > The correct dates are 4 to 10 of July 2026 :) > Sorry for the typo. > > S > >> On 19 Feb 2026, at 11:02, stephane ducasse via Pharo-users<pharo-users(a)lists.pharo.org> wrote: >> >> Hello Happy Smalltalkers >> >> Here is the call for presentation for ESUG 2026. >> >> The ESUG board is pleased to announce Call for presentations at the 31th ESUG conference to be held in >> Plovdiv, Bulgaria 7 - 10 July 2026. >> >> We are looking for YOUR experience on using Smalltalk. >> You will have 30 min for presentations and 45-60 min for hand-ons tutorial. >> >> The list of topics for the normal talks and tutorials includes, but is not limited to the following: >> >> - Micro Services, Container, Cloud, Big Data, >> - XP practices, Development tools, Experience reports >> - Model driven development, Web development, Team management >> - Meta-Modeling, Security, New libraries and frameworks >> - Educational material, Embedded systems and robotics >> - SOA and Web services, Interaction with other programming languages >> - Teaching Pearls >> - Show us Your Business >> - Show your business 10 min session (Get prepared!!) >> >> ## How to submit? >> >> - Submission deadline is 1st of May 2026 >> - Notification of acceptance will be on done on the fly. >> >> Pay attention: the places are limited so do not wait till the last minute to apply. >> >> Prospective presenters should submit a Pull Request on *https://github.com/ESUG/esug.github.io/tree/source/2026-Conference/talks>https://github.com/ESUG/esug.github.io/tree/source/2026-Conference/talks* >> >> If you do not succeed to do a PR you can send an email to<omar.abedelkader(a)inria.fr> and<stephane.ducasse(a)inria.fr> with [ESUG2026] in the title >> >> = Title: Please follow the template below the email will be automatically processed! >> = Name: >> = Email: >> = Abstract: >> = Bio: >> >> Any presentation not respecting this form will be discarded automatically. -- ----------------------------------------------------------------------- objektfabrik GmbHmailto:jtuchel@objektfabrik.de Fliederweg 1http://www.objektfabrik.de D-71640 Ludwigsburg HRB 798847 Telefon: +49 7141 56 10 86 0 Amtsgericht Stuttgart

UKSTUG Meeting: Adrian Soma - VEO: A Live Visual Smalltalk environment - 25 February 2026

by UK Smalltalk

Introducing VEO: A Live Visual Smalltalk that reimagines what a Smalltalk programming environment can be. VEO enables direct visual manipulation of any object and the creation of windowless visual interfaces. It is built around four core principles: all objects are visual; a single infinite zoomable and pannable canvas serves as the workspace; code can be written "in the air" anywhere in that space to send, evaluate and animate messages and live expressions; and live expressions can freely combine symbols, literals and live object references. Adrian Soma began his professional programming career in 1987, with a longstanding focus on the fundamental challenges of programming itself â particularly user interface design and interaction. He first encountered Smalltalk in 1996 and has worked with it ever since. An early project that would prove formative was an interactive chess course application, for which he built a custom graphical object system from scratch. That system became the first seeds of VEO, the Live Visual Smalltalk environment he has been researching and developing since 2006. This will be an online meeting. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/ukstug/events/312911115/ ) to receive the meeting details.

AI based test generation

by Kasper Osterbye

Cheers I am at the moment experimenting with getting an AI to write test methods for me. The current results are a mixture of simple and advanced :-) To get started I wanted to write tests for a class that does not go to the web, file or UI, and doing something which is standard, but with no method comments. So the experiments is for the class "Heap". I have not really been successful, but now I have what I see as a breakthrough, and wanted to know if anyone else had the same experience? -- Kasper Here is an example Heap >> upHeap: anIndex "Check the heap upwards for correctness starting at anIndex. Everything below anIndex is ok." | value k kDiv2 tmp | anIndex = 0 ifTrue:[^self]. k := anIndex. value := array at: anIndex. [ (k > 1) and:[self sorts: value before: (tmp := array at: (kDiv2 := k bitShift: -1))] ] whileTrue:[ array at: k put: tmp. self updateObjectIndex: k. k := kDiv2]. array at: k put: value. self updateObjectIndex: k And the test build by AI is this: testUpHeap | arr | "Test upHeap: for index 0, should do nothing" refHeap upHeap: 0. self assert: true. "No error, no change expected" "Set up min-heap sort block" refHeap sortBlock: [ :a :b | a <= b ]. "Test upHeap:1 on single element, no change" arr := Array new: 10. arr at: 1 put: 5. refHeap instVarAt: 1 put: arr. refHeap instVarAt: 2 put: 1. refHeap upHeap: 1. self assert: ((refHeap instVarAt: 1) at: 1) equals: 5. "Test upHeap:2 with swap needed (smaller child)" arr := Array new: 10. arr at: 1 put: 3. arr at: 2 put: 1. refHeap instVarAt: 1 put: arr. refHeap instVarAt: 2 put: 2. refHeap upHeap: 2. self assert: ((refHeap instVarAt: 1) at: 1) equals: 1. self assert: ((refHeap instVarAt: 1) at: 2) equals: 3. "Test upHeap:2 with no swap (larger child)" arr := Array new: 10. arr at: 1 put: 3. arr at: 2 put: 4. refHeap instVarAt: 1 put: arr. refHeap instVarAt: 2 put: 2. refHeap upHeap: 2. self assert: ((refHeap instVarAt: 1) at: 1) equals: 3. self assert: ((refHeap instVarAt: 1) at: 2) equals: 4. "Test upHeap:3 with one swap to root" arr := Array new: 10. arr at: 1 put: 3. arr at: 2 put: 4. arr at: 3 put: 2. refHeap instVarAt: 1 put: arr. refHeap instVarAt: 2 put: 3. refHeap upHeap: 3. self assert: ((refHeap instVarAt: 1) at: 1) equals: 2. self assert: ((refHeap instVarAt: 1) at: 2) equals: 4. self assert: ((refHeap instVarAt: 1) at: 3 )equals: 3. "Test upHeap:4 with multiple swaps" arr := Array new: 10. arr at: 1 put: 1. arr at: 2 put: 3. arr at: 3 put: 2. arr at: 4 put: 0. refHeap instVarAt: 1 put: arr. refHeap instVarAt: 2 put: 4. refHeap upHeap: 4. self assert: ((refHeap instVarAt: 1) at: 1) equals: 0. self assert: ((refHeap instVarAt: 1) at: 2) equals: 1. self assert: ((refHeap instVarAt: 1) at: 3) equals: 2. self assert: ((refHeap instVarAt: 1) at: 4 )equals: 3. And the input to make it doit is AIATest04 new build: Heap >> #upHeap:: I have added a tool call that allows Grok to call and execute Pharo code, so to produce the test, it has executed these calls: ApiToolExpression: Heap compileAllFrom: 'Collections-Sequenceable'. Heap methods select: [:m | m selector = #upHeap:]. Heap instVarNames ApiToolExpression: Heap instVarNames ApiToolExpression: Heap >> #add: sourceCode ApiToolExpression: (Heap >> #add:) sourceCode ApiToolExpression: (Heap >> #reSort) sourceCode ApiToolExpression: Heap new instVarNamed: #indexUpdateBlock
