This document provides specifications for a 10G 1553.33nm 80km DWDM SFP+ transceiver. It includes details on the product description, features, optical and electrical characteristics, and pin definitions. The transceiver uses a cooled EML laser transmitter and APD receiver to support transmission distances up to 80km over single-mode fiber at data rates from 9.95 to 11.3 Gb/s. It also includes a digital diagnostic monitor interface for real-time access to operating parameters.
Accelerate your Kubernetes clusters with Varnish CachingThijs Feryn
A presentation about the usage and availability of Varnish on Kubernetes. This talk explores the capabilities of Varnish caching and shows how to use the Varnish Helm chart to deploy it to Kubernetes.
This presentation was delivered at K8SUG Singapore. See https://feryn.eu/presentations/accelerate-your-kubernetes-clusters-with-varnish-caching-k8sug-singapore-28-2024 for more details.
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.

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.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Serial Interface for ID and Digital Diagnostic Monitor
DWDM-SFP10G-80-C30-T02 transceiver support the 2-wire serial communication protocol as defined in
the SFP+ MSA. The standard SFP+ serial ID provides access to identification information that describes
the transceiver’s capabilities, standard interfaces, manufacturer, and other information. Additionally, This
SFP+ transceivers provide an enhanced digital diagnostic monitoring interface, which allows real-time
access to device operating parameters such as transceiver temperature, laser bias current, transmitted
optical power, received optical power and transceiver supply voltage. It also defines a sophisticated
system of alarm and warning flags, which alerts end-users when particular operating parameters are
outside of a factory set normal range.
The SFP MSA defines a 256-byte memory map in EEPROM that is accessible over a 2-wire serial
interface at the 8 bit address 1010000X(A0h), so the originally monitoring interface makes use of the 8 bit
address(A2h), so the originally defined serial ID memory map remains unchanged. The structure of the
memory map is shown in Table1.

Typical Interface Circuit
Recommended power supply filter
Note:
Inductors with DC resistance of less than 1Ω should be used in order to maintain the required voltage at
the SFP input pin with 3.3V supply voltage. When the recommended supply filtering network is used, hot
plugging of the SFP transceiver module will result in an inrush current of no more than 30 mA greater
than the steady state value
