Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Keywords: AI, Containeres, Kubernetes, Cloud Native

Elasticity vs. State? Exploring Kafka Streams Cassandra State StoreScyllaDB
kafka-streams-cassandra-state-store' is a drop-in Kafka Streams State Store implementation that persists data to Apache Cassandra.
By moving the state to an external datastore the stateful streams app (from a deployment point of view) effectively becomes stateless. This greatly improves elasticity and allows for fluent CI/CD (rolling upgrades, security patching, pod eviction, ...).
It also can also help to reduce failure recovery and rebalancing downtimes, with demos showing sporty 100ms rebalancing downtimes for your stateful Kafka Streams application, no matter the size of the application’s state.
As a bonus accessing Cassandra State Stores via 'Interactive Queries' (e.g. exposing via REST API) is simple and efficient since there's no need for an RPC layer proxying and fanning out requests to all instances of your streams application.

18. Common Network Devices
Repeater
Repeater is used in coaxial cable network.
Also acts as signal amplifier or booster
Only 4 repeater connected in a cable network
19. Hub
Hub is used to connect multiple devices
Each port broadcast to find its device every time for
communication. Due to this heavy traffic occurs. All time this
process is repeated to find MAC address.
Slow communication
Also known as multiport repeater
Multiple communication is not possible at a time.
Other wise collision occurs.
Normally works only on 10 mbps.
20. Switch
It is also used to connect multiple devices
There is a MAC address table in switch, in that it will save MAC
addresses of all connected devices and its corresponding ports.
These information are saved on the first time of broadcasting from a
port. This process is not repeated for the next time of
communication.
More faster
Also known as Multiport Repeater or Intelligent Hub.
Multiple communication is possible at a time.
Therefore reduces collision.
Normally works on 10/100/100/10000 .. mbps
21. Bridge
Provide connections between LANs.
Not only do bridges connect LANs, but they also perform a check
on the data to determine whether it should cross the bridge or not.
This makes each part of the network more efficient.
22. Router
Routers are used to connect multiple networks.
Router is first found by CISCO in 1984.
Further more companies like Enframe, Checkpoint, Juniper, Huawei,
etc. started manufacturing routers.
