Open Shortest Path First
The document provides an overview of the Open Shortest Path First (OSPF) routing protocol, including that it is an interior gateway protocol that uses link state routing to establish neighbor relationships and exchange routing information within an autonomous system in order to determine the shortest path between any two routers on a network. OSPF detects changes in network topology quickly and converges on a new loop-free routing structure within seconds, and it has been widely implemented in large enterprise networks to provide efficient routing.
OSPF Basics
Open Shortest Path First (OSPF) is an interior gateway protocol that uses link state routing and the Dijkstra algorithm to calculate the shortest path to destinations within an autonomous system. It elects a Designated Router to generate network link advertisements and assist in database synchronization between routers. Routers run the Shortest Path First algorithm on their link state databases to determine the best routes and populate their routing tables.
Routing and OSPF
- OSPF is a link-state routing protocol that is more scalable than RIP. It builds a complete "map" of the network to avoid routing loops.
- OSPF uses link-state advertisements and flooding to exchange routing information between routers. It elects a designated router and backup designated router to optimize this exchange.
- Routers using OSPF establish neighbor relationships, synchronize their link-state databases, and calculate the shortest path to all known destinations using an algorithm on the link-state database.
RIP - Routing Information Protocol
Distance vector routing is an algorithm where each node maintains a routing table with the distances to all other nodes and shares this table periodically with its neighbors. Nodes initially only know the cost to directly connected neighbors and update their tables based on information received, potentially leading to a "count to infinity" problem if routes oscillate. Solutions include using split horizon to not pass back the source of a route and poison reverse to mark such routes as infinite. RIP is an implementation of distance vector routing that shares updates every 30 seconds.
Routing Information Protocol
RIP (Routing Information Protocol) is a standard routing protocol that exchanges routing information between gateways and hosts. It works by limiting routes to a maximum of 15 hops to prevent routing loops. There are three versions of RIP: RIP version 1 supports only classful routing; RIP version 2 adds support for VLSM and authentication; and RIPng extends RIP version 2 to support IPv6. RIP has limitations such as a small hop count limit and slow convergence times. It is commonly implemented in Cisco IOS, Junos, and open source routing software.
Routers and Routing Configuration
Router is a networking device that connects different networks and selects the best path to forward packets between them. It operates at the network layer of the OSI model. Cisco is the leading router manufacturer, making 70% of the market. Routers come in different sizes for different uses - access routers for small networks, distribution routers for ISPs, and core routers for backbone networks. Static routing requires manually configuring routes, while dynamic routing uses protocols to share route information between routers automatically.
IP Routing Tutorial
This document provides an overview of IP routing and routing protocols. It begins with a high-level explanation of how routing works on the internet through IP addressing and packet forwarding. It then discusses the history of routing, from static routing in early networks to the development of dynamic routing protocols. The rest of the document outlines key interior gateway protocols like OSPF and IS-IS, exterior gateway protocols like BGP, and concepts like autonomous systems and routing policy.

Epistemic Interaction - tuning interfaces to provide information for AI support
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.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex Proofs
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
