Digital Twin applied to Software
by Aik-Siong Koh Nov. 30, 2022

Nov. 30, 2022

Hi: I have a novel idea "Digital Twin applied to Software". See attached slides. It points to the future of improved programming productivity and reliability. Let me know what you think. Thanks, Aik-Siong Koh http://ar-cad.com Abstract Digital Twin applied to Software Aik-Siong Koh askoh.com There has been a major dichotomy in computing right from the beginning: Statically Typed vs Dynamically Typed programming languages. The former languages produce fast executables but are inflexible to program. The latter are just the converse. This dichotomy has been frustrating to programmers who always feel they have to make sacrifices when making a choice. It also often leads to futile language wars. The Digital Twin concept was introduced in engineering where a physical system is modeled digitally in geometry, simulation and other information. The concept has proven so successful that it is being applied to almost everything in engineering from simple mouse traps to complex whole cities. It occurred to the author that this concept can be extended to software too. For example, execution in C++ is famously fast. But development in C++ is notoriously difficulty because of language complexity and long build times. A flexible digital twin can be a program written in Smalltalk which is famous for live programming. "Development at the speed of thought" is the motto and is real. What is gained by this duplication? Firstly, the flexible twin can be use to explore new algorithms, features, solutions and fix bugs quickly. Only desired codes are translated to C++ manually or automatically. Secondly, the two programs can check each other so that bugs are reduced significantly. These two gains will define future programming productivity and quality. The Digital Twin concept will also drive the automatic translation of the flexible language to the fast language. Bio Dr Aik-Siong Koh has a PhD from The University of Texas at Austin where he programed in FORTRAN to simulation mechanical systems. While teaching at Texas Tech University and Nanyang Technological University, he developed interest in Multibody Dynamics. To develop his own Multibody Dynamics simulator, he researched for the most productive programming language and discovered Smalltalk. The live programming capabilities of Smalltalk permitted him to build a successful simulator which he then proceeded to commercialize. His later experience with C++ at Mechanical Dynamics and MathWorks gave him the idea of Digital Twin for Software.

We merged 18 PRs Lots of improvements related to BlockClosures this week. First some helper methods on the AST: - #hasNonLocalReturn: check if there is a non-local return - #isConstant: Blocks of the kind [#justSomeLiteral] - #constantValue: return that literal (and nil for empty [] ) - #numArgs for RBBlockNode, as we have already for BlockClosure "[:a | ] sourceNode numArgs" Some improvements for isClean: - unify between AST and BlockClosure - more tests - inlined blocks can be clean, important as it is recursive: [true ifTrue: []] should be clean - cleanup code in CleanBlock, receiver is known to be nil Compiler support for ConstantBlockClosure: - We can specialize clean blocks of the kind [#justSomeLiteral] to execute faster - add ConstantBlockClosure, add compiler support, active when compiling with clean blocks enabled Compiler support for full block without outer context: - we only need the outerContext for non-local returns. - add support to IRBuilder for full blocks without outer context - implement compiler support (option #optionBlockClosureOptionalOuter, false for now) Quick return for Blocks: - Compile quickreturn for CompiledBlock, just like CompiledMethod (e.g. for [^1]). - speeds up execution a little (but of course not creation) Block Closures ============== - AST: add a recursive #hasNonLocalReturn and #isConstant #11882 https://github.com/pharo-project/pharo/pull/11882 - add #numArgs to RBBlockNode #11902 https://github.com/pharo-project/pharo/pull/11902 - CleanBlock cleanup code: there should be no receiver ivar #11884 https://github.com/pharo-project/pharo/pull/11884 - 11881-RBBlockNodeisClean-takes-every-optimized-block-to-be-not-clean #11890 https://github.com/pharo-project/pharo/pull/11890 - 1883-CleanBlockChecker-does-not-recurse-into-the-blocks #11900 https://github.com/pharo-project/pharo/pull/11900 - ConstantBlockClosure: active when compiling with clean blocks enabled #11894 https://github.com/pharo-project/pharo/pull/11894 - CompiledBlocks: compile quick returns #11907 https://github.com/pharo-project/pharo/pull/11907 - IRBuilder: add support for outerContext flag for Closure creation #11905 https://github.com/pharo-project/pharo/pull/11905 - 11911-Compiler-add-compiler-option-for-outerContextNeeded #11917 https://github.com/pharo-project/pharo/pull/11917 Fixes ===== - Register-as-basicInspector #431 https://github.com/pharo-spec/NewTools/pull/431 - 11803 return value of inspect should be the receiver and not a sp window presenter #11886 https://github.com/pharo-project/pharo/pull/11886 - Fixes #429, VersionBrowser: left pane empty #430 https://github.com/pharo-spec/NewTools/pull/430 - Turn off ReLongMethodsRule for test methods #11892 https://github.com/pharo-project/pharo/pull/11892 - ClassParser: Implement #asSlot to return a correct Slot instances for complex slots #11898 https://github.com/pharo-project/pharo/pull/11898 - Fixes #11802 - Adds full consistency checks to class Time #11891 https://github.com/pharo-project/pharo/pull/11891 - Fixing to correctly get the VM for running the tests #11897 https://github.com/pharo-project/pharo/pull/11897 - Fixes #429, VersionBrowser: left pane empty #430 https://github.com/pharo-spec/NewTools/pull/430 Cleanup ======= - 11810-FT2Handle-classstartUp-compiled-code-on-image-startup #11811 https://github.com/pharo-project/pharo/pull/11811 Comments ========= - fixing comments in package Regex #11888 https://github.com/pharo-project/pharo/pull/11888

Improved Inspectors for Blocks
by Marcus Denker Nov. 25, 2022

Nov. 25, 2022

The inspectors for blocks are now a bit improved: 1) CompiledBlock. This now is more in sync with CompiledMethod and shows - the homew method code with the block highlighted - the AST of the block - the IR if the block Currently, we compile every non-optimized block to a full block that created by a bytecode from a CompiledBlock (which itself is stored as a literal). inspect âCompiledBlock allInstancesâ to see the new inspector: 2) BlockClosure itself, e.g inspect some block in the workspace. This gets more important as we soon will have pre-compiled subclasses of BlockClosure as method literals (and then just execute pushLiteral: to âcreateâ the block). A nice way to play with these is: CompilationContext optionConstantBlockClosure: true. OpalCompiler recompileAll. some 2500 of the blocks are now compiled statically. Inspect: ConstantBlockClosure allSubInstances The inspector shows the same (home method with highlight, IR, AST) But we can do even better: CompilationContext optionCleanBlockClosure: true. OpalCompiler recompileAll. Another 7500 blocks can be statically compiled, inspect CleanBlockClosure allInstances These are not yet the default, as we have to carefully analyse the places where we now assume that blocks know the outerContext and receiver. (in the example above you see one of these: Announcementsâ¦). You can follow these issues to see what still needs to be done: [Meta] Steps needed for ConstantBlocks #11933 https://github.com/pharo-project/pharo/issues/11933 [Meta] Steps needed for CleanBlocks #11195 https://github.com/pharo-project/pharo/issues/11195 Marcus

Looking for an engineer position to work on Virtual Machines
by Pierre Misse-Chanabier Oct. 25, 2022

Oct. 25, 2022

Hello, My name is Pierre Misse-Chanabier. I'm finishing my PhD in the RMOD team on testing Virtual Machines in about two months. I am therefore looking for a Job, hopefully in the Pharo community ! Ideally, I'm looking to work in the domains of Virtual Machines or Language Tooling, or Meta-programing, but I'm open to other opportunities. See my CV attached. I have to stay in Lille for at least the next year, therefore, I am looking to work remotely. Here are my most important projects and publications about them: Illicium : a framework to generate C code from Pharo code. Github repository: [ https://github.com/hogoww/Illicium | https://github.com/hogoww/Illicium ] IWST'19 Illicium: A modular transpilation toolchain from Pharo to C [ https://hal.archives-ouvertes.fr/hal-02297860/ | https://hal.archives-ouvertes.fr/hal-02297860/ ] version poster SAC'22 & full ICSR'22: Differential testing of simulation-based VM generators: automatic detection of VM generator semantic gaps between simulation and generated VMs [ https://link.springer.com/chapter/10.1007/978-3-031-08129-3_7 | https://link.springer.com/chapter/10.1007/978-3-031-08129-3_7 ] [ https://dl.acm.org/doi/abs/10.1145/3477314.3507171 | https://dl.acm.org/doi/abs/10.1145/3477314.3507171 ] Polyphemus: Retro engineering of the Pharo Image, and ease of VM tooling Github Repository: [ https://github.com/hogoww/Polyphemus/ | https://github.com/hogoww/Polyphemus/ ] Video Presentation for Esug Innovation award (I was unable to present it myself): [ https://www.youtube.com/watch?v=zf3cCtNW830 | https://www.youtube.com/watch?v=zf3cCtNW830 ] VMIL'22: Ease VM Level Tooling with Language Level Ordinary Object Pointers [ https://hal.inria.fr/hal-03827632 | https://hal.inria.fr/hal-03827632 ] (preprint) I am particularly interested in my latest work: Polyphemus. I have also worked on many part of the Pharo ecosystem. The Pharo VM, The Pharo bootstrap, Calypso, Debugger, selector extraction, Iceberg scripting, SUnit ...
