KEYNOTE PRESENTATION "WiFi -The Real 4G"
Brough Turner Founder -netBlazr.com
Wireless is at a tipping point and WiFi leads the way. LTE and WiMAX are relative laggards, as innovation shows up in WiFi first. This session will look at current WiFi deployments, current and future opportunities, and illustrate why we are the tipping point of Broadband Wireless.
As presented at the 4G Wireless Evolution conference in Miami, January 22, 2010.
WiFI has been at the heart of the change to OFDM and MIMO solutions. It is not suprising that WiFi is a hotbed of innovation in today’s marketplace. This discussion looks at the current and future opportunities associated with WIFI and the implications for new kinds of deployment and adaptation by the LTE and WiMAX community.
Brough’s keynote address at the October 2010 4G Wireless Evolution Conference.
In it, he argues:
1. All key 4G technologies are pioneered by Wi-Fi (3-5 year lead!).
2. Wi-Fi will be the dominant solution for mobile data offload.
3. 4G technologies represent a wireless tipping point with the result they will revolutionize backhaul and eventually the first mile (via wireless ISPs).
He closes with two slides on his new wireless ISP, netBlazr.

Wifi 6E vs 5G - which is more relevant to education and research?
TeliaSonera was the first operator in the world to commercially launch 4G. It was in late 2009, in the city centres of Stockholm and Oslo. 4G is the short term for fourth-generation wireless. It is still a research lab standard , the stage of broadband mobile communications that will supersede the third generation (3G). It is expected that end-to-end IP and high-quality streaming video will be among 4G's distinguishing features.
A 4G system will be able to provide a comprehensive IP solution where voice , data and streamed multimedia can be given to the users on “ Anytime Anywhere ” basis and higher data rates than the previous generations.
It will be a fully IP based integrated system capable of providing between 100 Mbps to 1 Gbps in both indoor and outdoor with premium quality and high security.
It is going to be launched in the year 2010.

ATIC Summit - Community Broadband Workshop 11/13/12Mark Goldstein
The Arizona Telecom & Information Council (ATIC) recently held a Broadband Summit. This is the slide deck from the Community Broadband Workshop that I anchored and put together. Session description was "A primary strategy of the Digital Arizona Program (DAP) is to provide funding, technical assistance, and support to the four rural Councils Of Government (COGS) and/or local communities to create Broadband Planning Committees. These committees and other stakeholder groups will develop and implement plans to expedite deployment of affordable high speed broadband services to their rural communities and to enable those communities and citizens to use next generation Broadband to support 21st Century education and workforce development, create jobs and support economic and community development, enhance public safety as well as health care and government services, and connect their citizens to the world. When you attend this workshop you will learn about resources, strategies, and tools to support the development of your community plans and engagement of your community's stakeholders."
Lte Forum Sweden April 2010 Ventura Lte DiscussionAirov8
Ventura addresses the question of whether it makes sense for legacy 900GSM operators in the UK to bid on 800MHz spectrum in view of a proposed sub-1GHz cap on spectrum. Using our suite of wireless technology models, we calculate under different network clutter types for Greater London and Cambridgeshire the conditions under which it would make sense to deploy LTE in 2.6GHz, 800MHz, or persist with HSPA. Our conclusions validate anecdotal evidence that for legacy 900GSM MNO's, there is little to be gained from bidding on 800MHz unless to achieve deep rural coverage.
Ventura has a comprehensive suite of network technology models that are able to calculate network CAPEX and OPEX for GSM, UMTS/HSPA, LTE and WiMAX for any spectrum allocation at any spectrum band. The suite has been designed with CTO technology selection decisions in mind and allows for multi-technology comparisons - quick and simple it isolates the major cost drivers from the perspective of the technology executive. The model outputs cumulative CAPEX, network cost/GB and customer profitability. Used in conjunction with our revenue and market share model, the combined suite can be used to undertake detailed business planning and valuation.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
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.pdfPaige Cruz
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:
