Almost every application needs data to function - and if you don't know how to be nice to your data, then things will start to go wrong. This talk aims to convince JavaScript developers that they do need to care about statistics, and then talk about how to do so. We look at some theory and lots of case studies and real-world advice to deal with a range of scenarios.
The talk aims to touch on the entire data life cycle: We'll dive into data modelling and how the shape and size of your data affects your architecture, and how to build these architectures using JavaScript. Once the data is in the front-end, we'll touch on the wide range of libraries that allows your code to react based on the data, and the wrappers on top that aid visualisation and readability.
This talk introduces microservices as a tool in an API developer's arsenal. We'll introduce what they are, see how and why they could fit into a modern application (and when they may not), and tools that will make dealing with a microservices architecture easier than ever before.
All too often front-end JavaScript code has been considered a second class citizen, and when treated without due care and attention it can be buggy and hard to maintain. This attitude is changing though, and thanks to the rapid growth in popularity of JavaScript as a first-class language, there is a large and expanding ecosystem of tools that a developer should know to make their client-side code as “clean” as the rest of their stack.
This talk aims to introduce and discuss how to implement modularisation, functional idioms and testing in JavaScript in an idiomatic way, to allow you to code JavaScript to a higher quality and, ultimately, more sustainably.
Data Modelling is an important tool in the toolbox of a developer. By building and communicating a shared understanding of the domain they're working with, their applications and APIs are more useable and maintainable. However, as you scale up your technical teams, how do you keep these benefits whilst avoiding time-consuming meetings every time something new comes along? This talk reminds ourselves of key data modelling technique and how our use of Kafka changes and informs them. It then examines how these patterns change as more teams join your organisation and how Kafka comes into its own in this world.

100% Visibility - Jason Yee - Codemotion Amsterdam 2018Codemotion
Monitoring systems has traditionally been the responsibility of Ops teams. But our goal is to align devs, ops, & other roles in the organization (aka DevOps), so we need to ensure they are all monitoring critical business systems & do so in ways that take advantage of the unique perspective that each role offers. In this session, I’ll break down the expansive monitoring landscape into 5 categories that each provide a unique view of your systems. I’ll show how each category allows your team to have complete observability, avoid blind spots, & work together to quickly resolve issues & outages.

Wrangle Your Defense Using Offensive Tactics BSides CT 2019Matt Dunn
The key to a good defense is understanding the offense. Grab your lasso and hop in the saddle because this talk will cover attack techniques that are regularly used to compromise networks and how they can be leveraged by the blue team to build a stronger defense. Forget vulnerability scanners, in this talk we cover issues they rarely catch, which include: Discovering unknown weaknesses externally and internally, weak passwords, in-memory credential theft and privilege abuse.
Learn how to discover, exploit and defend against those weaknesses using a number of free and/or open-source tools, as well as defense tips and the IOCs needed to tune your SIEM. Lastly, the MITRE ATT&CK framework will be introduced, so that you can utilize the same tactics on the entire gamut of known attack vectors.

Scaling your Tableau - Migrating from Tableau Online to a proper DWH solution...Sergii Khomenko
Initially storing data with Tableau Online storage could sound like a good idea, mainly because you get it for free. From another side Tableau doesn't say they provide a DWH platform, so you can not expect any kind of production use-cases from the storage of Tableau Online. In the talk, we will go through the process of automatically duplicating your Tableau datasources to Amazon Redshift. That will enable us to be more flexible with scaling your data, be sure about backup strategies and many-many more points. We will introduce our python toolchain that helps us in a daily management of our BI.
SEWM'14 keynote: Mining Events from Multimedia StreamsJonathon Hare
Keynote at the ICMR 2014 Workshop on Social Events in Web Multimedia (SEWM). Glasgow, UK. 1st April 2014.
The aggregation of items from social media streams, such as Flickr photos and Twitter tweets, into meaningful groups can help users contextualise and effectively consume the torrents of information on the social web. This task is challenging due to the scale of the streams and the inherently multimodal nature of the information being contextualised.
In this talk we’ll describe some of our recent work on trend and event detection in multimedia data streams. We focus on scalable streaming algorithms that can be applied to multimedia data streams from the web and the social web. The talk will cover two particular aspects of our work: mining Twitter for trending images by detecting near duplicates; and detecting social events in multimedia data with streaming clustering algorithms. We will describe in detail our techniques, and explore open questions and areas of potential future work, in both these tasks.
The slides cover Introduction to Big Data and Data Science, as well as go over our current and future projects @eHarmony.
eHarmony was founded to give people a better chance to find happy, passionate and fulfilling relationships.
During this talk I will describe steps that we go through to create Compatible matches and how we leverage Big Data technologies to accomplish that goal.
I will specifically talk on how we take Billion+ potential matches that we find through MongoDB, store them in Voldemort NoSQL datastore and then run multiple Hadoop jobs to come up with filtered list based on Machine Learned models.
Our hadoop clusters are in-house, high density, low power Seamicro installations and we use Spring Batch and Spring Data Hadoop to orchestrate the hadoop jobs.
Did you know that eHarmony is responsible for 5% of all new US marriages and that more than 600,000 people already got married through us?

From Content Strategy to Drupal Site Building - Connecting the dotsRonald Ashri
Content strategy is, undoubtedly, a hot topic these days. A lot is being said that spans the range from concerns regarding the ability to display content on any device to the ability to drive engagement and increase traffic through better content creation and social media strategies. In this presentation we will connect the dots between these issues and practical Drupal site-building concerns with tools that are readily available now.
We will show, through specific examples and references to available modules, how different approaches to content strategy can be practically implemented on Drupal sites. The aim is to equip Drupal site-builders with a handy toolkit that will allow them to both implement a content strategy for their sites as well as better exchange information with content strategists.
The examples will include:
- Different approaches to building content types so as to empower content creators to create a range of different structures.
- Best practices in using vocabularies (fixed, open, user-generated, moderated, etc) or where alternative categorization methods may be relevant.
We will also discuss:
- Editorial calendars and scheduling.
- The true benefit of workflows (and how, sometimes, they can be a disadvantage).
- Analytics and how the ability to measure the effects of any strategy is as important as defining the strategy itself.
Attendees will go away with practical examples and techniques that they can apply to their sites as well as a better understanding of what content strategy really is and how they can use it to improve their sites.
The examples are a result of our own experiences in helping both clients develop their content strategy as well as applying it on italymagazine.com, an in-house product of ours. We grew italymagazine.com to a relevant online digital brand with a strong community by expressing our content strategy ideas through the tools that Drupal 7 made available to us. The resulting ~250% increase in traffic over 3 months is a testament to both the value of a content strategy as well as the power of Drupal to allow you to flexibly and iteratively support it.

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.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
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).

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

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.
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
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.

66. • Data is any information we collect. Not all data is
valuable.
• Seeing trends in lots of numbers is hard. Summary
statistics and charts help us unpick its meaning.
• Data can be treated as random ‘realisations’ from a
backing distribution.
• Making random variables is easy, and can be done in
different shapes for different purposes.
