⁅ ~"There are genuinely three kinds of BareMetal[1] computers! CPUs, GPUs, AI" - Jim Keller, [and Tensor TPUs, and AI Divergent Processors!]

CPUs Processors/Programs: ~"80% of execution is about 6 [assembly] instructions!:
Instruction Sets (X64, ARM, Risc-V) only matter a little bit! .. What limits computer performance? The two big ones are instruction/branch-predictability and data locality." - Jim Keller.

GPUs Processors/Programs: ~"GPU guys will say look there is no branch predictor because we do every thing in parallel the chip has way more adders and subtractors and that is true if that is the problem you have but they are crap at running C programs! GPUs were built around shaders and pixels. ... thousands of threads... An army of ants crarrying around grains of sand! The shader problem is inherently small as there are so many pixels." - Jim Keller.

AI Processors/Programs: ~"Bigger Matrix Mutliplies and smaller number of threads that do a lots more math because the problem is inherently big!" - Jim Keller.

The fourth kind of computer (that is relevant for this article and Smalltalk-80 descendants⁆ is Divergent Processors using (300mm or larger) large waffer scale (or smaller chips) that can vary the mixture of CPU cores, GPU cores or AI cores (possibly TPU cores) on the same chip die! I know of one so far that is propostously very wide long word instruction words (really bit streams) that can bring together the transistor compute resources in 8-bit computing chunk units gluing them together for the type of computing and data flows that are needed; need an instruction that brings together maxtrix math with short Brain Integer or BFloat data cells but that also combines long 24 to 96 or more bit addresses for a computation space, and you can create custom - possibly higly parallel instrutions that correctly parallel flow the data from the on the fly transistor compute-memory-data-buses as needed resources, and in the next instruction that can be different! Both Smalltalk-80 descendant pure ZokuTalk™ MOBS™ (Messages, Objects & Data, Blocks Syntax) Messages based Object Oriented style programs "All The Way Down to The BareMetal[2] No Virtual Machine", Smalltalk-80 style virtual machine BareMetal[3] procedural & C-Style programs, GPUs stype massive pixel computations, or massive data intaking AI programs with many thousands of layers are all possible at the same time! Not to mention impressive Input/Output capacity, as the chip grows the communications grows in the third dimention!

Or combinations of any of these as well. ZokuTalk™ is being designed and is being implemented to keep up the the state of the art processors from all the top vendors (such as Apple, ARM, Intel, AMD, SiFive and many others first on 64 bits and then backtracking to 32 bits not mention the 128 bits of platentary scale server address spaces (e.g. Risc-v-128 Death Star); if and when the Divergent Propostously Very Long Bit-Stream Instruction Set Computing chip (excellent for CPU, GPU and AI processing word loads) comes out with motherbards and coputer boxes ZokuTalk will be there! ⁆.

   tags: {#Smalltalk. #Pharo. #WhyAreWeNotAllUsingSmalltalk}

{At the end of his video "Noel Rappin" he asks why are we not all using Smalltalk? Noel Rappin's assessment and conclusion is dead on target ◎!.}.

{From the beginning Smalltalk, even before Smalltalk-80 came out to the world, was the Operating System! In clear terms Smalltalk lost the OS Wars to C based OSes such as *nix aka NeXTStep/OpenStep/MacOS/iOS, oh and of course Unix, and later on Linux OSes where C Reigns Superme! Ironically Steve Jobs saw Smalltalk at Xerox Parc PLace labs that one day and created the MacIntosh! Later on Steve Jobs created NeXTStep using Objective-C a C based Smalltalk-like extention to C... sort of; at least it was messages and the NSApplication Kit is pretty wicked especially NSView which kicks ass in the GUI UX space.}

{ }

{This is one reason ZokuTalk is absorbing the Alien Data Formats and Alien Language Syntaxes with the ZokuTalk Tower of Babel™ Syntax Tool, to "play well with others". That is not the whole story as many other things need to happen to play well with others! For instance creating DLLs aka Shared Libraries from Smalltalk-80 descent code and have that be called by other programs from Alien Languages such as C or C++! Consider it Alien FFI's (Foreign Function Interfaces)! ZokuTalk has impressive access to FFI's with minimal effort as well.}.

{Unlike some others embracing Smalltalk-80 as "the one true and only solution", I play well with others using whatever the work demands! Yes that includes C or C++ or even C#! Or "shell" scripts on *nix or Windows! How dare I use Windows! Why would I not use Windows when almost a billion people are using Windows? Sure I love the MacOS and iOS and have owned many Apple products from the Apple ][ to the first MacIntosh with 1 MiB to the MacII with a 5GiB Harddrive to the last MacBookPro with an actual hardware ethernet port! Building ZokuTalk I embrace every major OS and Processor that exists much like COG does to support Squeak, Pharo and other Smalltalk-80 descendants! Oh, I support the awesome processors that don't yet exist as ASIC Chips (other than FPGA existence) that show promise! The goals it not take over the world with the "one true system" but to "play well with others" in the global computing landscape of the interwebs!}

{"Ruby is Smalltalk without the image with C syntax" - Robert Martin quoting Kent Beck.}

{ }

{Test driven development was and is the core disipline at Geiko's Smalltalk Development team with something like 10,000 or so tests (taking four or more hours to run) that had to pass for your code to be accepted, and it had to also pass a number of code reviewers who could kick it back to you! Oh and they used an extensively evolved version of SUnit. This approach enabled few bugs to get into production as the costs of shutting down some 10,000 Geico Telephone Operators was astronomical! One day such a shutdown happened as they rolled out a new version of the system and I got the call to come in and help! When I arrived there where already 50 people working the problem! Yikes!

Within a few hours after I backtracked to their annoyance going over the problem from the start I did testing and with the help of a Mainframe IBM Database Cobol expert who was in our section of the office I found the beg and documented as proof that it was a bug on the Cobol side! Her and I walked to her neck of the woods about two blocks away indisde the builing's widy path and presented the findings! They didn't believe me but hey evidence is evidence in computer science when you are following the scientific method as I do!

Later that day one of the Smalltalker's on our team who had extensive Cobol experience and I (mostly him with me verifying if it made sense) found the problem and tested it making the bug go away! They then reviewed the problem and went live an hour later; basically it was IBM's version of Cobol DLL Hell loading the prior version of the Cobol Library (one character was not updated in the database of which Cobol Library to load instead of the new one! Test driven development rules! Loss of one day's work of 10,000 operators, and the loss of customers having changes to their vehicle insurance policies adjusted, and 50+ techical people spending the day solving the problem.

ZokuTalk uses many tests for TDD even in the finished product so that Applications can test that ZokuTalk is working correctly as ZokuTalk has many Invariants that Must Hold True in order to Provide Guaranteed Safety of Transactions and other aspects of the Run Time and ZokuTalk Execution Engine.

{"Smalltalk has mystique. We talk about it more than we use it.

It seems like it should be so similar to Ruby. It has similar Object-Oriented structures, it even has blocks. But everything is so slightly different, from the programming environment, to the 1-based arrays, to the simple syntax. Using Smalltalk will make you look at familiar constructs with new eyes.

We'll show you how to get started on Smalltalk, and walk through some sample code. Live coding may be involved. You'll never look at objects the same way again."}.

{In the video "Peter Lount" by Idempotence in ZokuTalk explored in depth.}.

{"Idempotence: a math and computational quality given the exact same input objects/data operation messages the result will be the same ("same power") regardless of where or which computer it runs on or when it runs, in 1986 or 2022. Of course you need to run same version of the code if the outputs will be changed in a new version - fortunately the version of the code that is run for any computation is logged with the transaction, idempotent or not! After all ZokuTalk is fully versioned object+data system!"}.

{

}.
{}.

{ZokuTalk's research has focused on bringing advanced Live Programming features to life in many ways with all kinds of different models.

For example:

{}. {}.
(1) Going far beyond Closure's simplistic technocratic expertise required expertise for doing programming with complex "state" machinations and at the same simplifying the model and making one far more powerful that also enables wide and diversified program safety as well as Functional - when one wants it - Idempotent as appropriate and if needed.}.

ZokuTalk treats the changes to "state" of the "data/objects" as a primary aspect of the purpose of a progam, not to be avoided or feared but embraced and done in a safe atomic transactional manner with integrity and consistency isolated from other changes in a fully mulithreaded manner on N-Core-Threading processors or across distributed compute servers and being fully versioned durable on strorage as required!).

On the other hand functional languages have a helter-shelter problem with the flux of state changes in a typical enterprise application which is very strange as in real world applications most of the entire point is making correct and appropriate changes to data objects being modified aka changing (adding, deleting, adjusting, modifying) the state! At successful commits a new version of the object graph being modified or created is produced with a "version state", the same result that functional programs jump through many unnecessary mental hoops to achieve!.

Important Note: Idempotence as a programming technique is not owned by solely by Functional Programming as they would like you to magically believe, I used Idempotence as a key feature in "Gemstone Healer" in 6502 Assembly in the 1980's to generate the entire Dungeon Network and Room Details 100% from one 12 digit seed input!!! Two users entering the same seed get the same dungeon map as someone else does, sharing the seed value! In 1985 or in 2022!).

Smalltalk can do idepotence if one is manually very careful while ZokuTalk can do Systematic Idempotence to ensure it happens when required (all inputs accounted for and versioned, no external inputs not in the definded inputs) and Systematic Idempotence can be very important when doing massive distributed calculations across a cluster of compute servers across the Interwebs or inhouse on the available corporate computers especially when fault tollerance is important.

Oh and we don't have to confuse the matter as Functional Languages do by mixing State with Idempotence and being anti-state as a result! Lol, they have confusion at the core... by denigrating "changing state" as having no value! Changing State is how the Computational Universe operates as Stephen Wolfram has proven and it is wise to not go against his proofs!!!

Idempotence is an important technique for producing the same computational results for the same inputs! That is especially important in many (but not all) distributed processing requests across mutiple threads on one box or across a distributed cloud cluster on the interwebs. Why? if a distributed thread fails, say due to a loss of network communications, the particular thread work unit can be restarted on another server for fault tolerance recovery and completion of the distributed work flow!

{}.

(2) Easy distributed programming! Same process with real Native Threads! Different processes on the same box! Different distributed boxes/nodes in a compute cloud or shared across the Interwebs!...

(3) The GUI UX design brings the most advanced Visual Spaces for Work Productivity and Graphical Display of information! Bringing the best of most advanced Dynamic Interface Builders that are inherently flexible for dynamic rearrangement within a live programming GUI-UX design and live data, objects, messages, threads! Yes you can see processes and kill as needed! And bring them back to life if you need to!
...
...
...

(N) The list goes on and on, as the ZokuTalk research is very extensive with over 35+ years of research! The design of ZokkuTalk has talk a number of decades to solve certail problems to be performant and solve the safe parellel problem with millions of possible threads on a X64 bit scale CPU. I am working on implementing the ZokuTalk systems and writing about the ZokuTalk research. Suppport in form of funding is required.

I first read about Smalltalk in 1979 in an American Scientific article, followed by the Byte Magazine dedicated to Smalltalk in 1980! Wow that blew my mind! During working in 6502 Assembly Language for Gemstone Warrior, and later Gemstone Healer, video games I implemented my first Objects in 6502, yes there were only nine objects but they had some uniform characteristics, call them "map objects" for each game room. I also ported Gemstone Warrior to the Macintosh with a Motorola 32-Bit Hard Core 680000 CPU. After the games I worked in 6502 Assembly on a game system with many more objects and attempted to make a tiny Smalltalk, and failed when I realized the PC was ascendant.

In 1985 I obtained Smalltalk from Apple for the Mac Plus with 1 MiB of RAM! Wow! The next six months was warping my mind with unary, binary and keyword message sends and learning the Smalltalk Object library! It took about six months for me to feel comfortable with Smalltalk and to break out of 10+ years of procedural programming (that I started in my teens).

In 1987 I worked for Synaptec making a clone of Smalltalk for the Intel 386/486 based on ForthTalk, a variation on forth that had been objectified with Smalltalk message syntax too. I worked with Synaptec a number of times over the subsequent years as that was the era of the post 1987 Black Friday Stock Market kerfuffle.

Doing projects in Digitalk V/286 on the PC and Macintosh II I created a number of wicked apps in cad and desktop publishing! That lead to working with Condor Rebar Detailing where a civil engineer, an expert in segmental bridges, and I build the Vancouver Sky Train (it is a raised bridge above land) Bridge Extension into Surrey. I worked with Condor many times on the bridge program to extend it for vechicle bridges crossing rivers and waterways. A total of about 25 bridges where made with this software and we ported it to Digitalk V/Win where it was excellent! I also extensively worked on the Condor Rebar Detailing Program.

In 1992 I worked at JP Morgan at 60 Wall Street on Das Kapital using ParcPlace VisualWorks on the Core Technology Team and two former Parc Pllace people including one of the people who made up the original Smalltalk team!.

The reason I dive into a bit of history about my Smalltalk working experiences is to illustrate the path towards ZokuTalk has been a windy road with lots of mountains to climb from a learning and techniceal point of view with a continued research interest at making Smallktalk-80 better and better since I decided that in about 1987 after the first stint at Synaptec, my first Smalltalk-Variant Vendor. One of the issues to make better was real yet safe native-OS multithreading for Smalltalk. A thousand other aspects are affected by these Design Decisions including the ZokuTalk MOBS Extensions.}

{Smalltalk has always embraced the Baremetal+App+BC-VM+No-OS of real processors! At first these "Alto" and other processors were made in house at Xerox in the early days of computing and ran Byte Code Virtual Machines with No-OSes, the application was the OS, Smalltalk-7X where X is Smalltalk 71-76 leading to Smalltalk-80 before Smalltalk was released to the world! Since then the vast majority of Smalltalk-80 and descendant systems have run on mainstream real processors! X86, ARM32, and since 64 bit systems came out X64 (from AMD and Intel) and ARM64 processors including Apple's innovative ARM64 M1 and soon M2. This series explores the very real hardware Baremetal+RAW-Processors that we can actually run real Smalltalk-80 and descendant systems on! Recently Risc-V has entered the scene with shipping processors and motherboards or FGPA open source processors for the daring.}.

With more modern Smalltalk-80 and descendant systems having moved away from relying on Byte Code VM systems performance has increased to be viable! As Smalltalk-80 has away from early Smalltalk's Alto App+BC-VM+No-OS systems (Xerox era at the start) that has been fantastic for popular usage as almost all computers have an OS! Byte Code VMs are bad things it turns out! We co-exist in the real world with OSes and Real Processor Hardware, it is shame to hobble the full power of the modern processors near magical abilities by limiting the instruction sets to a narrow set of limited byte codes!

I prefer real Baremetal+No-BC-VM applications without the limiting their full power with fake byte code virtual machines getting in the way of performance besides we know better now decades later. The original motivation of Fake Bye Code VMs was for portability unfortunately performance matters more in turns out an there are other ways to achieve portability of Smalltalk like systems!

While OS Vitualization Machine systems are popular and I might be installing them on the server hardware for their many advantages they are bascially out of the scope of the focus. Perforamce will almost certainly be better than on real machines sharing a work load with N-Vitrual-OSes!

{While there are amazing innovative efforts to make new FPGA and ASIC processor designs that are better able to deal with Smalltalk-80 Byte Codes or more efficient processors for object systems, and at some key points I'll cover them in articles. The primary focus of this Baremetal Article Series is on major shipping 32 bit and 64 bit processor architectures from AMD/Intel, ARM, Apple, and Risc-V real Bare Metal processors. Also any open sourced FPGA designs you can install a Smalltalk-80 descendant system on!

Massively Parallel New processors being developed now for Smalltalk-80 descendant systems really need to consider having many Risc-V 64 bit or 128 bit Cores or to have their Absurdly Flexible Very Wide Long Word Instructions be viable to allow other Alien Systems written in C, C++, C#, Java, Rust, Go, ... to be compiled and integrate otherwise they won't sell in mass quantities and will be predestined to fail to be viable in more than a niche market. They would also benefit from a binary translation capability to run Alien OSes from other Processor Architectures sucn as X64, ARM64, Risc-V64, etc... as Apple and other companies have used before.}.


{AMD brings out the Zen 4 Processors in the Fall 2022! The basic specs are a range of processors but the top of the line in the current released lineup is the AMD Zen 4 with 5 namometer process technology, a top of the line 7950X processor with 8/16 cores or 16/32 threads, fitting in a new AM5 socket connecting to the world with the motherboard controller X670e delivering PCIe 5.0 bus performance (double PCIe 4 and four times PCIe 3, eight times PCIe 2 speeds many of which are currently still in operation!) and utilizing very fast DDR5 memory (yeah like GPU memeory speeds).}

{AMD also released thei plans to continue shrinking the processor technology with Zen 4c and Zen 5 to 4-namometer and 3-nanometer sizes! Wow.}.

{Needless to say I am working to obtain 2 of these Zen4 system for the ZokuLab™ for building ZokuTalk™ with ZokuTalk's Safe-Multi-Threading Execution Engine (not a virtual machine as I am "Burning The Disc Packs") with all real OS processes and FULL ZokuTalk MOBS™ syntax all the way down to the #BareMetal! Counter to the rumors it is not "Turtles All The Way Down", it is "ZokuTalk MOBS (Messages, Objects+Data, Blocks (all four+ varieties) Syntax all the way daown to the Bare Metal! Heck even the Memory Garbage Collector is fully safe-multi-threading!

Yes first on X64 and then on ARM64 & Risc-V64 processors. Yes that means obtaining Apple's M2 ARM64 chip when it comes out and the Risc-V64 processors. Also interested in embedded FPGA Risc-V 32 or 64 bit processors for electronics (Iot) projects. Have to wait a bit to obtain at least 2 of the 128 thread chips with dual chip mother boards for 256 threads when these Zen4 server chips are available for the server room). Building real systems just got serious!

In the mean time I continue building ZokuTalk using Pharo (versions 6 and in the process of moving to 10 and collecting up all my code from earlier Pharo and Squeak versions) on the 10 or so X64 Intel and AMD boxes from 2012-2014 that I have in the ZokuLab and ZokuServer zones! This will be an Epic upgrade to a full safe-multi-threading distributed ZokuTalk Lisp+Smalltalk-80+ technology based systems! Oh yeah the Zen 4 will be epyc as well especially when the AMD 256 thread dual chip cpus be become real!

Unfortunately my Mac Book Pro died with a bad GPU and would need to replace the GPU on the board to fix it, decided to get an M2 ARM64 Mac and laptop when they are available.

As a side note my two favorite computer languages are Assembly and Smalltalk-80 varients and soon with ZokuTalk 1.0. X64 is a dream machine compared to the MOS6502 where I cut my assembly language skills with.}.

{}.

{"Dynamic programming languages have long had a reputation for being slow and inefficient. The perception was that more expressive semantics necessarily require a cost in execution time. This is beginning to change as the performance gap between static and dynamic languages is visibly closing with the work being done on optimizing JIT compilers for JavaScript, Python and Lua. What does it take to make dynamic languages fast? What can we do to make them even faster? Follow me on a tour of dynamic language optimization from Smalltalk and the LISP machine to Google V8 and beyond."}.

On Messaging, Objects, Encapsulation, Late Binding, & Idempotence
by Peter Lount, 20190629.



Expanding on Dr. Alan Kay's often quoted statement, the most important big idea is messages being passed between objects. Objects are also key as they provide packages of related data items and code that performs operations on the data or using the data for real world computations. Encapsulation of related data items and related code methods provides protection and hiding of the "state" aka the data that relates to the state of the object. The processing details are hidden and encapsulated within code methods which also provide "Untyped Lambda Calculus" late binding of messages to methods at runtime; there is only one "type", that of Object where everything is an object that responds to messages sent to it at runtime.

It is interesting that some in the Pure Functional Langauge domain have misinterpreted Alan Kay's comment to mean that "messages alone" are the big idea and that you don't require the storing or accessing of "state" (aka data, values in variables of an object) in Objects. They make this mistake or distortion of the full Alan Kay statement so that they can preserve their notion of "functional purity" aka "referential transparency" aka "reproducable deterministic behavior" aka "idempotence" of their pure function computational model where "pure functions" only compute using the function's inputs to produce it's outputs. The notion of an object violates this "pure" model as it stores state beyond the life of the pure function or accesses stored state not passed into the pure function.

The Pure Functional Language focus is needlessly too narrowed to the scope of a single pure function as their primary approach. Referential Transparency, Reproducable Deterministic Behavior, & Idempotence can be achieved in any scope size of computation involving millions of objects and thousands of methods as long as the entire computation scope has the pure or idempotent property of only computing using the inputs to compute the outputs (and not accessing stored state that was not part of the set of inputs or writing state that was not part of the output set of objects; actually this can be relaxed in some cases such as writing a not used for input log file).



The image above is an example of the use of an idempotent reproducable deterministic computation in ZokuTalk using the wider scope within a Block that contains an Object of the Cube class that instantiates an instance and fills in the x, y, and z dimensions using the input parameters to the block and then computes the result in an idempotent manner. This example is quite simple and can be done in any Smalltalk by sending the block value or value:value:value: with the inputs. ZokuTalk takes it further by ensuring that the computation within the block is a "pure isolated transaction" by preventing it from accessing state from outside the block and raising an exception if the code attempts to do so.

One reason that idempotent computations and processing is important and useful is that if a block of code, with as many objects as you want, is referrentially transparent, has reproducable deterministic behavior and is idempotent, aka a pure block, it can safely be executed in parallel with a simple fork operation in Smalltalk type systems, or even better it can be executed in parallel using a native operating system thread of its own (as long as the language system has parallel garbage collection or can guarantee no movement of the objects in the native os forked off threads, and can guarantee isolation from other threads modifying objects in use by computation thread).

In ZokuTalk enforcing "pure isolated transactions" provides a systematic gurrantee that such parallel execution is isolated thus thread safe as long as you also heed thread synchronization such as using a Future object, parallel join or other thread synchronization techniques.

Pure functions as well as pure referentially transparent idempotent blocks of code are timeless, in that they can be computed in parallel at any time in the past and present. If the results of the computation are cached one need not recompute when the same inputs are used again and referrentially transparency is achieved; many compilers make use this technique to great effect for optimizations.

There are many benefits to the ideas from pure functional programming languages that ZokuTalk has inherited, and that even other languages can take advantage of if the programmer takes the manual care to ensure the idempotence principle. Heck, in one video game I wrote in 6502 Assembly Language the game map generator was fully idempotent across copies of the game by just typing in the same 12 hexidecimal number into other copies the game! I wrote that game back in the mid 1980's before I even new about pure functional languages showing that these techniques have been around since the dawn of time of computing.

{Steve Jobs paid for a professional Caricature Artist to draw this caricature of me at a NeXTWorld Expo in San Francisco, and I also consulted one on one with Steve Jobs the result of which improved the OpenStep Application Kit (and Apple App Kit). ... I upgraded it today to indicate my brain has been replaced by technology and science brain! Also my hair was replaced, doh! Oh well, a bonus tradeoff.}.

{}.

{Advancing Smalltalk-80 to a whole new dimension of capabilities is what ZokuTalk™ is all about aiming at mass adoption of hundreds of applications in an expanding set of wide diverse areas. That is the target. Will it be achieved? Action through time makes it so!}.

{}.

{The Smalltak.org and Zoku™ servers at the Harbor Center in Downtown Vancouver are being upgraded; the network connections have been upgraded and a few glitches that took the sitea offline have finally been resolved. ZokuTalk's extensive Language Grammar Parsers are being implemented with serious advancements to the State of The Art of Computer Science. That is the target. Will it be achieved? Action through time makes it so!}.

{ZokuTalk prioritizes Messages per Alan Kay. The syntax of messages is refined to enable vast new capabilites with a new dimensional door that open unparallelled opportunites including in Safe Parallel Message sending, receiving, futures, and distribution to many ZokuNodes™ in a coprorate #ZokuCluster™ or Free Forming Cooperative Zoku Cluster on the Interwebs. Messages are the key distinction, along with other ZokuTalk essentials make up the MOBS™ syntax improvements.}.

{It is Messages all the way down, not Turtles! Messages!}.

{ZokuTalk Objects and Data, from simple to complex forms, enable the vast form of data to be absorbed, incorporated, and supported. The goal is any kind of data that is out there! Yes even, ick, Relational Data!}.

{Blocks of all kinds shake the objective reality of representation systems. I reviewed all the Smalltalk-80 syntax a few decades ago when I was researching extending Smalltalk-80 to go beyond. Alan Kay took notice and we had a few months of email exchanges about the grammar elements. I got the impression that Alan wanted to eliminate blocks, both () and [], similar to earlier Smalltalk systems, or HyperCard, which is a very worthwhile goal. However by that time the pure unadultarated power of Square Bracket Block Closures [] had infected my Quantum Braining Unit! Our research paths diverged into parallel universes!}.

{It was very nice to briefly communicate and interact on research with one of my heroes, Alan Kay. Now we can see the Full Power of a Fully Operational Battle Star, er, Battle Star ZokuTalk System with the Full Power of Expanded MOBS Blocks, actually the Full Power of all MOBS elements that work together to vastly increase the power of what computer systems can do for people!}.

{The Blocks part of MOBS:}.

{Parentheses Blocks for (... immediate execution ...), and

Square Bracket Block Closures [... deferred execution ...] value do what they do in typical Smalltalk-80 and far beyond as both are upgraded to open new dimensions and capibilities.}.

{Additional new dimensional doors are opened with Curly Bracket Nested Alien Text {...{... immediate execution ...}...} enabling the re-presentation of #AlienGrammars to be incorporated into ZokuTalk source code, parsed and dealt with in other ways, communicated, and stored in ZokuTalk Object Data Stores!}.

{}.

{The most potent Blocks are doors to new dimensions created with Guillemets, sounds sort of like "gil-mets", are a pair of punctuation marks in the form of sideways double chevrons, « and », used as quotation marks, yes really, in a number of languages!}.

{ZokuTalk's «macros» enable the full first class general purpose ZokuTalk MOBS programming language, with «MOBS» syntax to be used for meta programming (as in incorporating much of the Lisp heritage)!}.

{Guillemets «macros» quote «Full First Class MOBS Syntax».}.

{No little language for «macros»!!}.

{Even the «Type system», primarily for interacting with Foreign Function Interfaces but also for Type Happy Programmers, in ZokuTalk uses the full general purpose language thus is can model far more possibilities than static type languages can with their very limited little type languages.}.

{«macros» execute at compile time!}.

{«macros» can modify the code the compiler generates, they can do compile time code construction of parts or whole systems, they can rewrite code, they are also compile time system directives, and much much more! Of course the code in the «macro» can also be executed at immediate run time as in the IDE or deployed systems as needed!}.

{Blocks open multiple dimensions that won't be disovered until ZokuTalk 1.0 Independence Day IDE in is our hands to see what you can do with it. ZokuTalk is not your granfathers Smaltalk-80 or Lisp or Erlang or 100 other languages that provided insights and direct contributions, it is radical shift in Computing Science. It took years for the full expression of the power of Smalltalk-80 blocks to be fully applied, some times new optimized compilers (as in the case of #ifNil:ifNotNil: and variants) to be implemented. Innovating take time! Knowing what to innovate takes even more time!}.

{That is the target. Will it be achieved? Action through time makes it so! If I fail at least it was attempting to Invent The Future Beyond What others Imagine The Future To Be!}.}.

{Code is Messages is Objects is Blocks is Macros is Meta is Data is Text is Code... an Infinite Loop}.

{}.

{Don't worry about what others are doing to invent the future but don't igore them either! Innovate beyond inventing the future! The long future awaits and needs us!}.

{If you want to help with ZokuTalk contact me and send money or provide contract work!}.

   title: {"Liberating the Smalltalk lurking in C and Unix"}

{In the video "Liberating the Smalltalk lurking in C and Unix" by Stephen Kell" by at the Strange Loop Conference [1] he explores the dynamic capabilities of Smalltalk and how to add Metadata programming capabilities to C, and Unix giving more dynamic power to them.}.

{"What's the purpose of all this? Unix abstractions are fairly simple and fairly general, but they are not humane, and they invite fragmentation. By 'not humane', I mean that they are error-prone and difficult to experiment with interactively. By 'fragmentation', I mean they invite building higher-level abstractions in mutually opaque and incompatible ways (think language VMs, file formats, middlewares...). To avoid these, liballocs is a minimal extension of Unix-like abstractions broadly in the spirit of Smalltalk-style dynamism, designed to counter both of these problems."}.

{ }.

}.

{"Most programmers make a clear distinction between dynamic, interpreted languages such as Smalltalk and Ruby, and statically compiled languages such as C and C++. Dynamic languages are seen as being slow, yet easy to use, and with advantages of introspection, integrated tooling, flexibility and rapid prototyping. Compiled languages are seen as fast, yet lacking the aforementioned benefits, and requiring understanding of impenetrable binary files and esoteric tools. Interfacing the two is even worse, involving FFI "dark magic", complicated further by the fact that the infrastructures supporting one or other kind of language work quite differently. "Static" generate binaries sitting directly on the operating system, while dynamic languages exist inside interpreter-like virtual machines."

Does it have to be this way, or is there a unifying model? Can we get the best of both worlds: fast compiled binaries that nevertheless support introspection and other dynamism, and dynamic languages that integrate with compiled code without FFI magic? This talk introduces liballocs, an infrastructure which exposes the dynamism hiding in the arcane linking and debugging infrastructure of a Unix process, along with a small extension to C toolchains that enables fast dynamic access to data created by statically compiled code. Together they can be said to unleash a "hidden Smalltalk" inside the C and Unix model of programs and processes. Come prepared for a journey that takes your perceptions of the boundaries between dynamic and static languages and turns them on its head."}.

{I concur!

ZokuTalk™ really brings languages such as Smalltalk-80 with refined MOBS (Message, Object+Data, Blocks (all four kinds) Syntax) together in a more dynamic and dramatic way. Sure it is in progress, aways off but the design is on target! Easier FFI for example with ZokuTalk becoming the fastest way to leverage Linked Libraries loaded at runtime (to respect their Alien Licenses): load and use! Other features in progress!}.

Legacy Smalltalk.org Articles at Archive.org
Unfortunately due to unforseen issues Smalltalk.org servers crashed, as well as life unfolding, the doh backups were unrecoverable a number of times, and recently major internet hardware upgrades at Harbour Centre server room facility where the Smalltalk.org servers upgraded all their equipment and we had difficulty finding the DNS issues; these issues are resolved with new OSes being installed shortly. In the meantime here are links to Archive.org Smalltak.org articles as I work to get them back online intime using ZokuTalk systems.
