Distributed Refactoring with Gradle Lint

Jun 23, 20160 likes635 views

This document discusses Netflix's use of Gradle Lint to enable distributed refactoring. Gradle Lint allows Netflix to define custom linting rules to validate and refactor Gradle builds across their monorepo. The document provides an example of a rule to enforce that all WAR projects are published to their binary repository. It demonstrates how the rule can be made more complex by applying the change immediately, only if needed, or replacing the WAR plugin entirely.

The document discusses how cities can keep up with rapid technological change while avoiding hype. It notes that the number of transistors in integrated circuits doubles every two years according to Moore's Law, leading to exponential increases in computing power. However, city infrastructure changes slowly, occurring over generations. This leads to a perception of risk from drastic changes and limits investment in innovation. The document also discusses Gartner's Hype Cycle model and how brands have broken through hype to find real value from new technologies. It suggests cities can pace Moore's Law's changes and survive hype cycles by shifting from capital investment strategies to smooth change from operating investments, accelerating innovation through changed procurement policies.

How the internet of things will literally ruin the web - Gaëtan Godartblue2purple

��

This document discusses how the growth of internet of things devices and video streaming are straining internet infrastructure. It notes that 50% of internet traffic is now non-human as more devices connect to the internet. This trend will require massive investments in underwater cables and data centers to support rising data usage. There are also concerns about how all this additional data collection may impact privacy and lead to technology only being accessible to large companies able to pay for the infrastructure upgrades. The document advocates for more efficient use of internet resources to reduce the environmental impact.

Voxxed Days Belgrade - Spring Boot & Kotlin, a match made in HeavenNicolas Fränkel

��

Nicolas Frankel presents on the match between Spring Boot and Kotlin. He discusses why Spring Boot is useful for convention over configuration and out-of-the-box features. Kotlin is also discussed as being more expressive than Java with improved object oriented and functional features. Key benefits of Kotlin include being more expressive than Java, improved object oriented programming, and adding functional programming capabilities. Extension methods are highlighted as a killer feature that allows adding new methods on existing types.

Real World Event Sourcing and CQRSMatthew Hawkins

��

Event Sourcing, Domain Driven Design, and Command Query Responsibility Segregation – we hear all of these technologies used together frequently, but how do they actually work together? How do you manage complex co-ordination in a CQRS system? In this talk, we will discuss a real world example of DDD with ES and CQRS written in F# - a functional first language on the .NET Framework. We’ll take a deep dive into the F# algebraic type system that constructs the domain model. Also, the explanation of the abstract notion of a DDD aggregate root compared to the CQRS implementation of an aggregate root. Finishing with how sagas and triggers facilitate poly-aggregate communication.

The document discusses fiber optic deployment in Europe and regulatory models, and considers their applicability to broadband deployment in the United States. It finds that open access networks are more economically viable, and that neither duopoly nor vertically integrated private investment alone will achieve nationwide next-generation broadband access within 3-5 years without a profitable wholesale model. An "NGA-style" net neutrality approach of guaranteed wholesale capacity could enhance service competition.

This document discusses applications that are possible with gigabit internet speeds and localized computing infrastructure. It begins by showing current bandwidth and latency capabilities compared to applications' needs. It then describes technologies like gigabit wired/wireless networks and localized computing racks. Applications discussed include high-quality video, virtual/augmented reality, real-time sensor responses, and more. The document advocates for partnerships between cities, universities, businesses and more to develop these applications and create sustainable business models.

Whitepaper DVB Native IP: The Gamechanger for Content DistributionST Engineering iDirect

��

Native IP over Satellite doesn’t simply restrict its benefits to streaming services and broadcasters. There are a host of sectors that can take advantage of the standard. Aside from video, other file-based documentation can be transmitted using Native IP over Satellite technology. This, therefore, opens the door to a much wider range of users than those who solely consume OTT content. Here are just a few of the notable and emerging use cases where traction is being gained.

Local is the Lo in SoLoMo, the buzz word. Local is not only about location, it's also about your digital track record. Over 70% of Netflix users watch the films recommend. Mining data to understand people's behaviour is getting to be a huge and valuable business. Advertisers see opportunities in getting direct to their target groups. Predictive intelligence is also about where you will be at some time in the future, and where somebody you know will be. It turns out that Facebook and Google know you better than you think you know yourself. The world is about to get really scary.

Why are migrations important? This session will discuss how to put your databases on version control. The presentation is based on the assumption that the developer already knows about version control and is using it on their projects in some form. L-Migrator will be discussed in relation to its integration into PageBlocks and its stand alone use. Attendees will come away with a knowledge of the methodology behind migrations, why they are important and when to use them, as well as shortcuts and tips for writing Lasso Migrations and the dangers of performing destructive migrations.

SIMULATION OF FIR FILTER BASED ON CORDIC ALGORITHMVLSICS Design

��

Coordinate Rotation Digital Computer (CORDIC) discovered by Jack E Volder. It is a shift-add operation and iterative algorithm. CORDIC algorithm has wide area for several applications like digital signal processing, biomedical processing, image processing, radar signal processing, 8087 math coprocessor, the HP-35 calculator, Discrete Fourier, Discrete Hartley and Chirp-Z transforms, filtering, robotics, real time navigational system and also in communication systems. In this paper, we discussed about the CORDIC algorithm and CORDIC algorithm based finite impulse response low pass & high pass filter. We have generated the M-code for the CORDIC Algorithm and CORDIC Algorithm based FIR filter with the help of MATLAB 2010a.We also discussed about the frequency response characteristics of FIR filter.

Floating Offshore Wind in the Celtic Seapermagoveu

��

Floating offshore wind (FLOW) governance arrangements in the Celtic Sea case are changing and innovating in response to different drivers including domestic political priorities (e.g. net-zero, decarbonization, economic growth) and external shocks that emphasize the need for energy security (e.g. the war in Ukraine). To date, the rules of the game that guide floating wind in the UK have evolved organically rather than being designed with intent, which has created policy incoherence and fragmented governance arrangements. Despite this fragmentation, the UK has a well-established offshore wind sector and is positioning itself to become a global leader in floating wind. Marine governance arrangements are in a state of flux as new actors, resources, and rules of the game are being introduced to deliver on this aspiration. However, the absence of a clear roadmap to deliver on ambitious floating wind targets by 2030 creates uncertainty for investors, reduces the likelihood that a new floating wind sector will deliver economic and social value to the UK, and risks further misalignment between climate and nature goals.
