This document summarizes research on using magneto-optic imaging for non-destructive testing of metal structures. It describes developing new thin-film sensors with improved sensitivity, integrating the sensors and image recognition algorithms into a portable system, and applying a neural network algorithm called SONON to enhance defect detection in images. Laboratory experiments demonstrated the new sensors could detect smaller defects than previous methods. The overall aim is more accurate, automated inspections using portable, wearable equipment.
This document discusses a novel magneto-optic sensor called the MODE sensor that can be used for non-destructive testing of structural integrity. The MODE sensor uses thin films made of rare earth and transition metal oxides that have high magneto-optic properties, allowing it to detect cracks, fissures, and corrosion in structures. A portable system has been designed using this sensor to allow real-time inspection of bridges, fuel tanks, and other metal structures. The system includes image processing and pattern recognition capabilities to help identify defects.
The catalog contains all of Mshot products line, including optical microscope, LED fluorescence illuminator, microscope camera, thermal plate and other accessories.

The Evolution of Asynchronous Javascript - Alessandro Cinelli - Codemotion Mi...Codemotion
This document discusses the evolution of asynchronous JavaScript programming. It covers callbacks, promises, generators, and async/await. Callbacks were initially used but led to callback hell. Promises improved the situation by providing a cleaner way to handle asynchronous code but promise hell was still possible. Generators allowed blocking-like code using yield but required promises to handle asynchronous functions. Now async/await in ES2017 allows writing asynchronous code that looks synchronous and resolves many of the past issues. Streams are also mentioned as an alternative concurrency model to callbacks and async code.

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
The document summarizes some of the security issues with blockchain technology. It discusses how blockchain is not a "silver bullet" and does not inherently solve problems like privacy and security of smart devices. It outlines various application security issues with complex code, protocols, and difficulty of updates on blockchains. Concerns over data immutability and security of smart contracts are also covered. The document questions whether blockchain truly provides the level of decentralization and anonymity claimed, and outlines some impossibility results and limitations of existing approaches to achieving security and privacy in blockchain systems.

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.

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?

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.

Cosa hanno in comune un mattoncino Lego e la backdoor XZ?Speck&Tech
ABSTRACT: A prima vista, un mattoncino Lego e la backdoor XZ potrebbero avere in comune il fatto di essere entrambi blocchi di costruzione, o dipendenze di progetti creativi e software. La realtà è che un mattoncino Lego e il caso della backdoor XZ hanno molto di più di tutto ciò in comune.
Partecipate alla presentazione per immergervi in una storia di interoperabilità, standard e formati aperti, per poi discutere del ruolo importante che i contributori hanno in una comunità open source sostenibile.
BIO: Sostenitrice del software libero e dei formati standard e aperti. È stata un membro attivo dei progetti Fedora e openSUSE e ha co-fondato l'Associazione LibreItalia dove è stata coinvolta in diversi eventi, migrazioni e formazione relativi a LibreOffice. In precedenza ha lavorato a migrazioni e corsi di formazione su LibreOffice per diverse amministrazioni pubbliche e privati. Da gennaio 2020 lavora in SUSE come Software Release Engineer per Uyuni e SUSE Manager e quando non segue la sua passione per i computer e per Geeko coltiva la sua curiosità per l'astronomia (da cui deriva il suo nickname deneb_alpha).
