Generating a custom Ruby SDK for your web service or Rails API using Smithyg2nightmarescribd
Have you ever wanted a Ruby client API to communicate with your web service? Smithy is a protocol-agnostic language for defining services and SDKs. Smithy Ruby is an implementation of Smithy that generates a Ruby SDK using a Smithy model. In this talk, we will explore Smithy and Smithy Ruby to learn how to generate custom feature-rich SDKs that can communicate with any web service, such as a Rails JSON API.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
2. In English there is more than one
way to speak about the past…….
past simple
Past
progressi
ve
Present
perfect
past
perfect
3. The present perfect is a way to talk about
something that happened at an indefinite time
in the past and continues in the present. This
tense is also used when an activity has an
effect on the present moment
4. • Actions which happened at an
indefinite (unknown) time before
now
• Actions in the past which have an
effect on the present moment
• Actions which began in the past and
continue in the present
5. USE 1: Indefinite (unknown) time
before now
Use the Present Perfect to talk about actions
that happened at some point in the past. It
does not matter when exactly they happened.
Examples:
I have already had a breakfast.
He has been to England.
6. You should not use this tense
with time expressions like
"yesterday", "a week ago", "last
year", etc.
7. We also use this tense to when an activity has an
effect on the present moment.
Examples:
He has finished his work. (so he can now rest)
I have already eaten dinner. (so I'm not hungry)
He has had a car accident. (that's why he is in the hospital)
8. We often use the Present Perfect when we
want to emphasize that an event continues in
the present.
Examples:
Mary has worked as a teacher for over 25
years.
Patrick has achieved a lot in his life.
9. More examples:
She has never seen my brother.
Neither of my brothers has ever
driven a truck.
12. OK. Let’s go over the uses
again:
USE 1: Indefinite (unknown)
time before now
Use the Present Perfect to talk about
actions that happened at some point in
the past. It does not matter when
exactly they happened.
13. Use 2: Effect on the Present
Moment
We also use this tense to when an activity
has an effect on the present moment.
Examples:
He has finished his work. (so he can now
rest)
I have already eaten dinner. (so I'm not
hungry)
He has had a car accident. (that's why he is in
the hospital)
14. Use 3:We often use the Present
Perfect when we want to emphasize
that an event continues in the present.
How can we use
the present
perfect with
this picture of
Bibi?
15. Which use of the present perfect in these
examples; 1,2 or 3?
• I have bought new shades!
• I have already been to Paris.
• John has been a plumber for 2 years
• Someone has just taken my bag!
• Jane has never been so angry.
• He has been our most serious partner
for so long that I can assure you he's a
very reliable man.
16. Answers:
• I have bought new shades use 2
• I have already been to Paris use 1
• John has been a plumber for 2 years use
3
• Someone has just taken my bag! use 1,2
• Jane has never been so angry use 3
• He has been our most serious partner
for so long that I can assure you he's a
very decent man. use 3
