Business Value and Business Model Innovation in Decentralized Interoperabilit...Boris Otto
NisB—short for “The Network is the Business”—facilitates a network of heterogeneous information producers and consumers that share a common interest in harmonizing their knowledge assets. By trading knowledge assets, the network establishes and refines interoperability between its parties. The value of the accumulated interoperability knowledge in the network improves as more the network grows in parties and assets and that interoperability knowledge constitutes economic value in its own right.
The innovative idea is to maintain and refine knowledge, striving for overall consistency. Knowledge creation leverages crowd concepts and the multitude of relationships among individual information items in the same domain.
NisB introduces business model archetypes that base the sharing of interoperability assets on a sound economic model balancing investment with gain while stimulating usage. Based on the understanding that many small contributions generate a great value, incentive models and mechanisms will be developed by which realized value consumed by one will compensate the other underlying contributors
Technique to design Business Model from the book: Business Model GenerationRoukaya Issaoui

Scenarios are easy-to-use Data Analysis tools
Scenarios give a snapshot of what things would be like if certain conditions were to change.
A scenario contains sets of values that influence an outcome
They can be used to forecast the effects of just about anything
They are particularly useful in financial models
Using Scenarios for “What-If” Analysis
Scenarios can be named and saved with different sets of figures to represent specific values.
When several scenarios have been saved they can be viewed to compare the different results each would bring.
An example would be where you create a budget but are not sure of the amount of revenue your business will generate
A scenario can be defined for each predicted revenue figure and then switched between to calculate “what-if” analysis.
Scenario Reporting
You can create a Scenario Report from the scenarios you generate
This report can also be turned into a Pivot Table report
This makes it ideal for further analysis
Scenarios are great when the data sets become large.

"The “inevitable future” scenario-building methodology" by Artiom ZheltovArtiom Zheltov
The document introduces a scenario-building methodology called "The Inevitable Future" framework. It begins by describing limitations of traditional scenario frameworks that only consider a limited number of possibilities. The "Inevitable Future" framework combines trends with scenario variations to provide decision-makers with a large spectrum of options and strategies. It describes potential futures as "inevitable" or "impossible" based on trends. The framework results in descriptions of most probable scenarios and an outline of strategies to achieve a desired future. Examples provided demonstrate its use in foresight projects on topics like science/technology, energy, health, and regional development.

One of the greatest challenges to developing an API is ensuring that your API lasts. After all, you don’t want to have to release and manage multiple versions of your API just because you weren’t expecting users to use it a certain way, or because you didn’t anticipate far enough down the roadmap. In this session, we’ll talk about the challenge of API Longevity, as well as ways to increase your API lifecycle including having a proper mindset, careful design, agile user experience and prototyping, best design practices including hypermedia, and the challenge of maintaining persistence.
LF_APIStrat17_Connect Your RESTful API to Hundreds of Others in Minutes (Zapi...LF_APIStrat
You may have seen the articles or blog posts claiming something outrageous like how you can connect to hundreds of other Apps and enable thousands of use cases within a few hours of development.
They’re true. In this workshop, the Left Hook team will walk you through how to connect your App to hundreds of others on Zapier’s platform in a matter of minutes. There are a few big asterisks to achieve this speed: 1) Your API needs to be RESTful using either API token or OAuth2.0; 2) You’ll need to choose only a few basic use cases; 3) You need to be comfortable in a Node.js environment; 4) You need to be comfortable using a CLI tool.

PathSpotter: Exploring Tested Paths to Discover Missing Tests (FSE 2024)Andre Hora
When creating test cases, ideally, developers should test both the expected and unexpected behaviors of the program to catch more bugs and avoid regressions. However, the literature has provided evidence that developers are more likely to test expected behaviors than unexpected ones. In this paper, we propose PathSpotter, a tool to automatically identify tested paths and support the detection of missing tests. Based on PathSpotter, we provide an approach to guide us in detecting missing tests. To evaluate it, we submitted pull requests with test improvements to open-source projects. As a result, 6 out of 8 pull requests were accepted and merged in relevant systems, including CPython, Pylint, and Jupyter Client. These pull requests created/updated 32 tests and added 80 novel assertions covering untested cases. This indicates that our test improvement solution is well received by open-source projects.

The code is written and the tests pass. I just have to commit this last round of changes to my branch. Wait, why does that say committed to main? Did I commit all those changes to main? Arghh! I can’t redo all of this!
Committing changes to the wrong branch, forgetting files, misspelling the commit message, and needing to undo commits are some of the “advanced” features of Git that we normal people run into way too often and need help with. The fixes are often easy – once you know what they are. But in the heat of the moment, with the deadline (or Friday afternoon) approaching, it isn’t always easy to figure out what magic spell to cast to get Git to do what you need.
We’ll spend some time looking at typical Git situations people get themselves into, and then we’ll demonstrate how to get out of them. This isn’t about Git internals or a Git master’s class – this real-world Git when things aren’t going right. And there will be plenty of time for questions, so bring your “best” Git nightmare scenarios so we can figure out how to recover.

Predicting Test Results without Execution (FSE 2024)Andre Hora
As software systems grow, test suites may become complex, making it challenging to run the tests frequently and locally. Recently, Large Language Models (LLMs) have been adopted in multiple software engineering tasks. It has demonstrated great results in code generation, however, it is not yet clear whether these models understand code execution. Particularly, it is unclear whether LLMs can be used to predict test results, and, potentially, overcome the issues of running real-world tests. To shed some light on this problem, in this paper, we explore the capability of LLMs to predict test results without execution. We evaluate the performance of the state-of-the-art GPT-4 in predicting the execution of 200 test cases of the Python Standard Library. Among these 200 test cases, 100 are passing and 100 are failing ones. Overall, we find that GPT-4 has a precision of 88.8%, recall of 71%, and accuracy of 81% in the test result prediction. However, the results vary depending on the test complexity: GPT-4 presented better precision and recall when predicting simpler tests (93.2% and 82%) than complex ones (83.3% and 60%). We also find differences among the analyzed test suites, with the precision ranging from 77.8% to 94.7% and recall between 60% and 90%. Our findings suggest that GPT-4 still needs significant progress in predicting test results.
Test Polarity: Detecting Positive and Negative Tests (FSE 2024)Andre Hora
Positive tests (aka, happy path tests) cover the expected behavior of the program, while negative tests (aka, unhappy path tests) check the unexpected behavior. Ideally, test suites should have both positive and negative tests to better protect against regressions. In practice, unfortunately, we cannot easily identify whether a test is positive or negative. A better understanding of whether a test suite is more positive or negative is fundamental to assessing the overall test suite capability in testing expected and unexpected behaviors. In this paper, we propose test polarity, an automated approach to detect positive and negative tests. Our approach runs/monitors the test suite and collects runtime data about the application execution to classify the test methods as positive or negative. In a first evaluation, test polarity correctly classified 117 tests as as positive or negative. Finally, we provide a preliminary empirical study to analyze the test polarity of 2,054 test methods from 12 real-world test suites of the Python Standard Library. We find that most of the analyzed test methods are negative (88%) and a minority is positive (12%). However, there is a large variation per project: while some libraries have an equivalent number of positive and negative tests, others have mostly negative ones.
Monitoring the Execution of 14K Tests: Methods Tend to Have One Path that Is ...Andre Hora
The literature has provided evidence that developers are likely to test some behaviors of the program and avoid other ones. Despite this observation, we still lack empirical evidence from real-world systems. In this paper, we propose to automatically identify the tested paths of a method as a way to detect the method’s behaviors. Then, we provide an empirical study to assess the tested paths quantitatively. We monitor the execution of 14,177 tests from 25 real-world Python systems and assess 11,425 tested paths from 2,357 methods. Overall, our empirical study shows that one tested path is prevalent and receives most of the calls, while others are significantly less executed. We find that the most frequently executed tested path of a method has 4x more calls than the second one. Based on these findings, we discuss practical implications for practitioners and researchers and future research directions.

4. … a long time ago …
Our page is so slow to load
can you fix the performance problem ?
5. • The design
– /orders
– /orders/:id
– /orders/:id/details
– /products
– /products/:id
– …
5
The basic design
“A Home page showing the user’s open orders,
the order status, one product for each order
plus the thumb, and a list of the last 5 sent
orders” … What about performance ?
26 API Calls !!
“But our API is so RESTfull !”
What’s the problem ?
6. What’s the problem ?
What is a REST resource ?
Is you raw data model ?
Where is the Business logic ?
Where it should be ?
What if you need to release a new client ? (WebApp, Mobile, …)
7. What’s the problem² ?
• This is not a REST problem
– REST is a great way to expose data
• But…
– REST is not an excuse to expose your raw data model
– REST is not an excuse to stop thinking about business logic
“Smart Data & dumb code works a lot better
than the other way around“
The Cathedral & The Bazaar, Eric S. Raymond
Smart APIs, dump clients
Note : Batch requests could help, but business logic is still on client side...
9. Introducing Scenario Driven Design
1. Client analysis
– Identify client needs
– Usage scenarios
2. Service design
– Optimal ways to service the client
scenarios
3. Data modelling
– Create data model to support the
scenario’s
– Low level and high level concepts
4. Interface design
– REST/HAL etc. interface
– Versioning, etc.
Reminders :
• Data Driven Design
from Data to generic clients
• Client Driven Design
from Specific clients to data
11. Scenario Driven Design Approach
• Identify all relevant scenarios
– Order a movie
– Watch a movie
– See list of my movies
– Promote content on the home screen
– See what’s available
– Like/unlike movies
Interactions are platform-specific,
Scenarios usually aren’t.
12. Promote content on the home page
• All clients should present, on
their home screen, after login:
– The user’s most recently
rented movies
– User specific
recommendations
– Movie top 20
– Featured movies
13. Scenario Driven Design
(1) ‘Home’ screen
(4) /promoslots/home
(2) Promote content to the home
screen
(3) Movies, collections, banners,
14. Interface Design
• Exemples
– /recommendations
• or /users/@me/recommendations
– /promoslots/:screen
– /users/@me/movies
– /users/@me/movies/liked
– /movies
• Consider scenario’s at the highest level
– Business Logic entirely API side
– Important: find balance between generic and specific
15. Framework Design
Framework Design Guidelines: Conventions, Idioms,
and Patterns for Reusable .NET Libraries
by Krzysztof Cwalina & Brad Abrams
” Frameworks often contain a very large set of
APIs. This enables advanced scenarios that require
power and expressiveness. However, most
development revolves around a small set of
common scenarios that use a relatively small
subset of the full framework. To optimize the
overall productivity of the developers using a
framework, it is crucial to invest heavily in the
design of APIs that are used in the most common
scenarios.”
16. Do & Don’t
http://blogs.msdn.com/b/kcwalina/archive/2005/05/05/scenariodrivendesign.aspx
• Do make sure that the API design specification is the central part of
the design of any feature that includes a publicly accessible API.
• Do define top usage scenarios for each major feature area.
• Do ensure that the scenarios correspond to appropriate abstraction
level. They should roughly correspond to the end user use cases.
• Do design APIs by first writing code samples for the main scenarios
and then defining the object model to support the code samples.
• Do not rely solely on standard design methodologies (for example
UML) when designing the public APIs layer of a framework.
• Do not start API design with object model diagrams.
• Do organize usability studies to test APIs in main scenarios.
18. The example of Twitter API
• The Twitter API exposes many methods for tweets, favorites, retweets, followers,
search, …
• What is the most common feature of twitter ? => Timelines
• The home timeline is central to how most users interact with the Twitter service.
Do no try to reinvent the wheel
Dumb clients, Smart APIs
19. Office for Ipad
“designed for iPad” as opposed to “ported to iPad
• Several key mobile scenarios
– Packing up for the ride home
– Starting from scratch
– Last minute scramble
– Buttoning things up
– Collaborating with coworkers
– Taking notes
• “bringing over hundreds of
Office commands, toolbars,
and dialogs to the iPad would
be, simply put, a mistake.”
