OpenBTS - Building Real Mobile Networks, Big or Small
Speaker: Michael Iedema
"OpenBTS implements a complete GSM stack for voice and SMS. It also supports GPRS and UMTS 3G data standards. With an off-the-shelf server and SDR (software defined radio), it is now possible to build real mobile networks. These networks can be used to support true fixed-mobile convergence, bring coverage to remote areas or just experiment and innovate within the cellular network itself. Because OpenBTS converts all cellular signalling and media directly to SIP and RTP, the development environment should be familiar!"

- IP addresses are divided into network and host portions based on their class (A, B, or C).
- Subnetting allows a network to be divided into multiple subnets using subnet masks to define the network and host portions of IP addresses.
- When planning IP addressing, considerations include determining subnets, assigning addresses to subnets and hosts, and ensuring local and remote hosts can be identified.
ระบบเครือข่ายคอมพิวเตอร์
This document discusses home network technologies. It covers local area networks (LANs), wide area networks (WANs), and common networking protocols and standards. Some key points:
- LANs connect devices within a home or small office using technologies like Ethernet over twisted pair cable or WiFi. Common LAN topologies are bus, star, and ring.

FTTX and Triple Play
The document discusses FTTx and triple play integration using copper and fiber access networks. It describes an Ethernet point-to-point network using an active star topology with unlimited modems and distances up to 120km. The network provides low latency, 10Gbps maximum data rates per segment, and 95% efficiency. Compared to EPON, the P2P Ethernet network allows unlimited users per segment, longer distances, higher data rates, and greater efficiency and reliability. The document also outlines applications like IPTV, VoIP and video conferencing that drive bandwidth needs, and how a scalable network architecture using optical modems and switches can meet these needs.
networking
There are two main types of wireless topologies: ad hoc networks which connect wireless computers directly to each other, and infrastructure networks which connect wireless computers to a wired network via an access point. IEEE 802.11 standards define wireless networking protocols including 802.11a, 802.11b, and others. Common cabling systems include coaxial cable, fiber optic cable, and twisted pair cable. UTP cable standards like Category 5e support speeds up to 1 Gbps and are commonly used to connect devices within a local area network.

Mod8
The document summarizes key concepts about the OSI physical layer:
- The physical layer is layer 1 of the OSI model and is responsible for encoding and transmitting raw bits over a physical medium.
- It supports different network media like copper, fiber optic cable, and wireless. Standards bodies define specifications for these media.
- Encoding schemes convert bits to signals, like Manchester encoding and NRZ. More advanced schemes group and code bits for higher speeds.
- Different network media have advantages - fiber is immune to noise but more expensive than copper wire. Wireless allows mobility but has security and interference issues.
- Physical layer standards and technologies have evolved to support higher network speeds up to gigabits per second.

Mscict ns&i telecom fundamentals
This document provides an overview of networking fundamentals and telecommunications concepts taught in the MSCIT Networking Services & Infrastructures course. It covers topics such as signals, modulation, multiplexing, transmission media, switching techniques, architectural layers, protocols, and standardization bodies. The document consists of a list of topics and subtopics with explanatory slides and diagrams for each.
Local Area Network – Wired LAN
A local area network (LAN) uses wired connections to connect devices within a limited geographic area like a building or campus. Ethernet became the dominant wired LAN technology using carrier sense multiple access with collision detection (CSMA/CD) to regulate shared access to the transmission medium. Ethernet has evolved from 10 Mbps to 100 Mbps to 1 Gbps standards to meet increasing bandwidth demands. Key components of wired LANs include network adapters, cabling, connectors, switches/hubs, and software protocols. Other historical wired LAN technologies like Token Ring and Token Bus used token passing for medium access but have been largely replaced by Ethernet.

Artificial Intelligence for XMLDevelopment
In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

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:
