The document discusses the concept of perfection and feedback loops. Some key points:
- Perfection does not exist as context and problems are constantly changing. Feedback loops are more important than trying to build a perfect solution.
- Exponential growth means problems can increase enormously over time, so waiting for perfection means missing opportunities for improvement.
- Systems that incorporate feedback through iterative improvements can surpass "finished" solutions that lack feedback. Open source and agile development are examples.
- To build effective systems, focus on feedback loops rather than distant goals, and accept imperfection as progress is made through small iterative changes.

Abstract: This will a rather unusual talk for ESUG. The theme is not Smalltalk directly, but instead I discuss how progress and inventing new things fits with incremental, reflective nature of Smalltalk.
People often argue that progress is only possible when you throw everything away and start from scratch. In this talk I will argue that this thinking is a trap and the only way for progress in practice is to take an incremental approach of constantly improving and therefore evolving the imperfect system you already have.
I will show how the idea of creating feedback loops of improvement actually lead to non-linear growth and how this process of reflective constant improvement fits with the Smalltalk philosophy of incrementally and dynamically changing a running system.

Title: Replicated Service Objects -- A Strategy for Distributed Applications
Type: Talk
Abstract:
Early in the history of distributed Smalltalk applications, designers
built systems that provided transparent distribution. This enabled
distributed applications to be written almost as if they were on a
single machine. After the explosion of the Internet in the late '90s, it
was widely recognized that this approach led to applications that did
not perform well -- application developers needed to be aware of and
design around communication latency. One solution to this problem is
Replicated Service Objects, an architecture for distributed Smalltalk
applications that makes it easy to minimize the impact of network latency.
Bio:
Martin has been interested in Smalltalk since he first heard about it in
1975. After a frustrating ten-year wait he finally got his hands on a
running Smalltalk system and hasn't let go since. As a senior engineer
working on GemStone Smalltalk products at GemTalk Systems, he leads a
team that designs and implements a distributed object system that acts
as a bridge between a Smalltalk client and a GemStone Smalltalk server.
In his spare time, he works on Mist (a Smalltalk-like language with
improved modularity and security and no virtual machine) and does a lot
of contra dancing. Lately, he's been working on remodeling an old house
with attached former church which will become his home with built-in
dance hall.

Title: The Cog VM evolution
Type: Talk
Abstract: In 2008, the Squeak VM repository made by Dan Ingalls was
forked to give birth to the high-performance Cog VM, which is now the
default VM for multiple Smalltalk dialects such as Pharo, Squeak or
Cuis. Since the fork, new features and performance enhancements have
been introduced every year. This talk sums up all the main features
and main performance tweaks that were added to the Cog VM in
chronological order from 2008 to today. The focus is on the execution
engine: Memory management, interpretation, JIT compilation and FFI.
The talk lastly discusses the current work in-progress and short-term
future work.
Bio: Clément Béra is a PhD student working on virtual machines for
object oriented languages at Inria, Lille. He is now focusing on

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

This session equips you with the knowledge, tools, and techniques needed to troubleshoot and conquer OutOfMemoryError in all its forms, ensuring smoother, more efficient Java applications.
First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

Developing Distributed High-performance Computing Capabilities of an Open Sci...Globus
COVID-19 had an unprecedented impact on scientific collaboration. The pandemic and its broad response from the scientific community has forged new relationships among public health practitioners, mathematical modelers, and scientific computing specialists, while revealing critical gaps in exploiting advanced computing systems to support urgent decision making. Informed by our team’s work in applying high-performance computing in support of public health decision makers during the COVID-19 pandemic, we present how Globus technologies are enabling the development of an open science platform for robust epidemic analysis, with the goal of collaborative, secure, distributed, on-demand, and fast time-to-solution analyses to support public health.
Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.

Exploring Innovations in Data Repository Solutions - Insights from the U.S. G...Globus
The U.S. Geological Survey (USGS) has made substantial investments in meeting evolving scientific, technical, and policy driven demands on storing, managing, and delivering data. As these demands continue to grow in complexity and scale, the USGS must continue to explore innovative solutions to improve its management, curation, sharing, delivering, and preservation approaches for large-scale research data. Supporting these needs, the USGS has partnered with the University of Chicago-Globus to research and develop advanced repository components and workflows leveraging its current investment in Globus. The primary outcome of this partnership includes the development of a prototype enterprise repository, driven by USGS Data Release requirements, through exploration and implementation of the entire suite of the Globus platform offerings, including Globus Flow, Globus Auth, Globus Transfer, and Globus Search. This presentation will provide insights into this research partnership, introduce the unique requirements and challenges being addressed and provide relevant project progress.
Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

I did not know that Yogi Berra was a baseball player…
"I really didn't say everything I said.”

21. “By the time you’ve arrived at the *perfect* solution,
usually the problem has already changed.”
— Jessie Shefrin (@jshefrin)
22. Quote thanks to Jessie Shefrin
http://artthinking.com
Why is that?
24. Context changes.
Would the perfect Programming Language and
Environment for 1985 be seen as perfect in 2016?
And it goes even deeper than that. Context is everything.
The same solution can be good or bad, depending on the
context it is embedded in.
26. One of the first viral videos of the internet.
The video should never have been posted, it is often
shown as an example of cyber bullying.
Lots of things can be learned, but what everyone agrees:
“Perfection” is the last thing that comes into mind.
So you are seeing this…
32. When you are ready to finish, it will be obvious to you
that what you did is all bad. You could do so much
better… easily.
Now it is so obvious…
But the “old you” would love it. The old you did not yet
learn what the “new you” knows.
Keep in mind: everyone else but you did not learn what
makes you see your work as imperfect.
34. … but to some extend others (and the old you) will
see the problems, though. A finished artefact always
embodies its own critique.
(If you can see flaws in everything other people do,
maybe it is not because you are oh so clever?)
51. In a lake, there is a patch of lily pads. First
day there is one, second two. After long 47
days it is half full.
How long does it take to cover the whole lake?
52. 47 long days to do half.. will take a while for sure…
63. Example: Linux vs. Minix.
Minix was clearly better. But there was no
feedback loop for Minix.
Linux was a *process*, while Minix was a
finished artefact.
65. The first microprocessor was designed with paper +
pen.
You could not design a current one without having
already a computer.
(Going back to paper+pen… why not go back to
sticks+stones?)
Another Example: LAM builds machines that build
processors. These machines *contain* processors
themselves.
69. A startup just does not have resources for building
the perfect solution to a problem nobody cares
about.
Very hard to explain to our profession… spawned a
whole “self help book” section for Programmers.
78. From self help books: do not focus on the goal ("I want
