Rivivere l'ebbrezza di progettare un vecchio computer o una consolle da bar è oggi possibile sfruttando le FPGA, ovvero logiche programmabili che consentono a chiunque di progettare il proprio hardware o di ricrearne uno del passato. In questa sessione si racconta come dal reverse engineering dell'hardware di vecchie glorie come il Commodore 64 e lo ZX Spectrum sia stato possibile farle rivivere attraverso tecnologie oggi alla portata di tutti.
Il Commodore 65 è un prototipo di personal computer che Commodore avrebbe dovuto mettere in commercio quale successore del Commodore 64. Purtroppo la sua realizzazione si fermò appunto allo stadio prototipale. Racconterò l'affascinante storia del suo sviluppo ed il perchè della soppressione del progetto ormai ad un passo dalla immissione in commercio.

Fuzz-testing: A hacker's approach to making your code more secure | Pascal Ze...Codemotion
Increased complexity makes it very hard and time-consuming to keep your software bug-free and secure. We introduce fuzz-testing as a method for automatically and continuously discovering vulnerabilities hidden in your code. The talk will explain how fuzzing works and how to integrate fuzz-testing into your Software Development Life Cycle to increase your code’s security.
Pompili - From hero to_zero: The FatalNoise neverending storyCodemotion
It was 1993 when we decided to venture in a beat'em up game for Amiga. The Catalypse's success story pushed me and my comrade to create something astonishing for this incredible game machine... but things went harder, assumptions were slightly different, and italian competitors appeared out of nowhere... the project died in 1996. Story ended? Probably not...
Michel Schudel - Let's build a blockchain... in 40 minutes! - Codemotion Amst...Codemotion
There's a lot of talk about blockchain, but how does the technology behind it actually work? For developers, getting some hands-on experience is the fastest way to get familiair with new technologies. So let's build a blockchain, then! In this session, we're going to build one in plain old Java, and have it working in 40 minutes. We'll cover key concepts of a blockchain: transactions, blocks, mining, proof-of-work, and reaching consensus in the blockchain network. After this session, you'll have a better understanding of core aspects of blockchain technology.
Richard Süselbeck - Building your own ride share app - Codemotion Amsterdam 2019Codemotion
When was the last time you were truly lost? Thanks to the maps and location technology in our phones, a whole generation has now grown up in a world where getting lost is truly a thing of the past. Location technology goes far beyond maps in the palm of our hand, however. In this talk, we will explore how a ridesharing app works. How do we discover our destination?How do we find the closest driver? How do we display this information on a map? How do we find the best route?To answer these questions,we will be learning about a variety of location APIs, including Maps, Positioning, Geocoding etc.
Eward Driehuis - What we learned from 20.000 attacks - Codemotion Amsterdam 2019Codemotion
Eward Driehuis, SecureLink's research chief, will guide you through the bumpy ride we call the cyber threat landscape. As the industry has over a decade of experience of dealing with increasingly sophisticated attacks, you might be surprised to hear more attacks slip through the cracks than ever. From analyzing 20.000 of them in 2018, backed by a quarter of a million security events and over ten trillion data points, Eward will outline why this happens, how attacks are changing, and why it doesn't matter how neatly or securely you code.
Francesco Baldassarri - Deliver Data at Scale - Codemotion Amsterdam 2019 - Codemotion
IoT revolution is ended. Thanks to hardware improvement, building an intelligent ecosystem is easier than never before for both startups and large-scale enterprises. The real challenge is now to connect, process, store and analyze data: in the cloud, but also, at the edge. We’ll give a quick look on frameworks that aggregate dispersed devices data into a single global optimized system allowing to improve operational efficiency, to predict maintenance, to track asset in real-time, to secure cloud-connected devices and much more.
Martin Förtsch, Thomas Endres - Stereoscopic Style Transfer AI - Codemotion A...Codemotion
What if Virtual Reality glasses could transform your environment into a three-dimensional work of art in realtime in the style of a painting from Van Gogh? One of the many interesting developments in the field of Deep Learning is the so called "Style Transfer". It describes a possibility to create a patchwork (or pastiche) from two images. While one of these images defines the the artistic style of the result picture, the other one is used for extracting the image content. A team from TNG Technology Consulting managed to build an AI showcase using OpenCV and Tensorflow to realize such goggles.
Melanie Rieback, Klaus Kursawe - Blockchain Security: Melting the "Silver Bul...Codemotion
Blockchain (and Cryptocurrency) is an evolution of 20-year old research from scientists like Chaum, Lamport, and Castro & Liskov. Due to the current hype, it's hard to distinguish beneficial aspects of the technology from a desire for a "silver bullet" for device security, verifiable logistics, or "saving democracy". The problem: blockchain introduces new security challenges - and blind adoption without understanding reduces overall security. In this talk, Melanie Rieback and Klaus Kursawe explain the pitfalls and limits of blockchain, so you can avoid making your applications LESS secure.
Angelo van der Sijpt - How well do you know your network stack? - Codemotion ...Codemotion
Networking is a core part of computing in the digital world we inhabit. But, how well do you know how it works? Do you understand all the moving parts of the OSI stack inside your computer, and how the network is actually put together? How can this ever work? This guided safari of layers, standards, protocols, and happenstance will bring us close to the copper wire, and up through the layers of CDMA/CD, ARP, routing and HTTP. We will make a few excursions through patchworks that still work forty years later, and cleverly designed mechanisms that show that simplicity is the only way to last.
Lars Wolff - Performance Testing for DevOps in the Cloud - Codemotion Amsterd...Codemotion
Performance tests are not only an important instrument for understanding a system and its runtime environment. It is also essential in order to check stability and scalability – non-functional requirements that might be decisive for success. But won't my cloud hosting service scale for me as long as I can afford it? Yes, but… It only operates and scales resources. It won't automatically make your system fast, stable and scalable. This talk shows how such and comparable questions can be clarified with performance tests and how DevOps teams benefit from regular test practise.
Sascha Wolter - Conversational AI Demystified - Codemotion Amsterdam 2019Codemotion
Sascha will demonstrate the opportunities and challenges of Conversational AI learned from the practice. Both Technology and User Experience will be covered introducing a process finding micro-moments, writing happy paths, gathering intents, designing the conversational flow, and finally publishing on almost all channels including Voice Services and Chatbots. Valuable for enterprises, developers, and designers. All live on stage in just minutes and with almost no code.
Michele Tonutti - Scaling is caring - Codemotion Amsterdam 2019Codemotion
A key challenge we face at Pacmed is quickly calibrating and deploying our tools for clinical decision support in different hospitals, where data formats may vary greatly. Using Intensive Care Units as a case study, I’ll delve into our scalable Python pipeline, which leverages Pandas’ split-apply-combine approach to perform complex feature engineering and automatic quality checks on large time-varying data, e.g. vital signs. I’ll show how we use the resulting flexible and interpretable dataframes to quickly (re)train our models to predict mortality, discharge, and medical complications.
Pat Hermens - From 100 to 1,000+ deployments a day - Codemotion Amsterdam 2019Codemotion
Coolblue is a proud Dutch company, with a large internal development department; one that truly takes CI/CD to heart. Empowerment through automation is at the heart of these development teams, and with more than 1000 deployments a day, we think it's working out quite well. In this session, Pat Hermens (a Development Managers) will step you through what enables us to move so quickly, which tools we use, and most importantly, the mindset that is required to enable development teams to deliver at such a rapid pace.
James Birnie - Using Many Worlds of Compute Power with Quantum - Codemotion A...Codemotion
Quantum computers can use all of the possible pathways generated by quantum decisions to solve problems that will forever remain intractable to classical compute power. As the mega players vie for quantum supremacy and Rigetti announces its $1M "quantum advantage" prize, we live in exciting times. IBM-Q and Microsoft Q# are two ways you can learn to program quantum computers so that you're ready when the quantum revolution comes. I'll demonstrate some quantum solutions to problems that will forever be out of reach of classical, including organic chemistry and large number factorisation.
Don Goodman-Wilson - Chinese food, motor scooters, and open source developmen...Codemotion
Chinese food exploded across America in the early 20th century, rapidly adapting to local tastes while also spreading like wildfire. How was it able to spread so fast? The GY6 is a family of scooter engines that has achieved near total ubiquity in Europe. It is reliable and cheap to manufacture, and it's made in factories across China. How are these factories able to remain afloat? Chinese-American food and the GY6 are both riveting studies in product-market fit, and both are the product of a distributed open source-like development model. What lessons can we learn for open source software?
Pieter Omvlee - The story behind Sketch - Codemotion Amsterdam 2019Codemotion
The design space has exploded in size within the last few years and Sketch is one of the most important milestones to represent the phenomenon. But behind the scenes of this growing reality there is a remote team that revolutionizes the design space all without leaving the home office. This talk will present how Sketch has grown to become a modern, product designer's tool.
Dave Farley - Taking Back “Software Engineering” - Codemotion Amsterdam 2019Codemotion
Would you fly in a plane designed by a craftsman or would you prefer your aircraft to be designed by engineers? We are learning that science and empiricism works in software development, maybe now is the time to redefine what “Software Engineering” really means. Software isn't bridge-building, it is not car or aircraft development either, but then neither is Chemical Engineering. Engineering is different in different disciplines. Maybe it is time for us to begin thinking about retrieving the term "Software Engineering" maybe it is time to define what our "Engineering" discipline should be.
Joshua Hoffman - Should the CTO be Coding? - Codemotion Amsterdam 2019Codemotion
What is the job of a CTO and how does it change as a startup grows in size and scale? As a CTO, where should you spend your focus? As an engineer aspiring to be a CTO, what skills should you pursue? In this inspiring and personal talk, I describe my journey from early Red Hat engineer to CTO at Bloomon. I will share my view on what it means to be a CTO, and ultimately answer the question: Should the CTO be coding?
Mike Kotsur - What can philosophy teach us about programming - Codemotion Ams...Codemotion
If Socrates met Linus Torvalds, what would they talk about? How much math should be bundled into a good programming language? Can compiler resolve an argument and prove, that someone is right? Trough semantics of code, that we write every day, when looking carefully, one can see foundations of logic and science, that has been build more than 2000 years ago. Why does it matter, and how can we leverage this enormous power to make our code safe and sound in languages with advanced type systems, like Typescript and Scala.
Mete Atamel - Serverless with Knative - Codemotion Amsterdam 2019Codemotion
When you build a serverless app, you either tie yourself to a cloud provider, or you end up building your own serverless stack. Knative provides a better choice. Knative extends Kubernetes to provide a set of middleware components (build, serving, events) for modern, source-centric, and container-based apps that can run anywhere. In this talk, we’ll see how we can use Knative primitives to build a serverless app that utilizes the Machine Learning magic of the cloud.
