"Sviluppare Videogiochi in 2D con Unity" by Roberto De Ioris. Unity3D e' uno degli engine piu' utilizzati nel mondo del game development. Sebbene sia nato per realizzare giochi in 3 dimensioni, dalla versione 4 include il support per la grafica 2D. Il talk illustrera' quali sono gli step necessari per realizzarre un semplice gioco con animazioni, fisica ed effetti particellari, usando gli asset del videogioco Dolguth.

Why using an engine ?
Only one reason: focus on ideas/creativity and
less on coding
but…

The Mecanim system
animation clips and the Animator
all is curves !
root motion available

Optimizations from the 3D world
batching (for tilemaps)
occlusion culling on sprites !
auto atlasing (with tagging)

Porting all over the place
Linux, Mac and windows
XboxONE (no need to pay!)
Mobile (Android and iOS)
Working on the new AppleTV

Customizing the editor
automating tasks
ad-hoc tools

Tricks
Textures compression
Particle collisions (ﬁxed in 5.3 !)
multiple cameras for parallax

Optimizations without metrics are no-
optimizations
the proﬁler

Is it all beautiful ?
too much regressions :(
totally sub-optimal input system (XInput is a good solution on windows)
a bit immature networking system (things are changing)
still too much work on custom shaders
no navigation system for 2d (unless you work in 3d-style)
personal note: they need better integration with git

Looking at…
Skeletal-based animations
Free Form deformations
Invest more on the new networking api
Testing framework (pretty new)
The audio mixer

With further advancement in the current console cycle, new tricks are being learned to squeeze the maximum performance out of the hardware. This talk will present how the compute power of the console and PC GPUs can be used to improve the triangle throughput beyond the limits of the fixed function hardware. The discussed method shows a way to perform efficient "just-in-time" optimization of geometry, and opens the way for per-primitive filtering kernels and procedural geometry processing. Takeaway: Attendees will learn how to preprocess geometry on-the-fly per frame to improve rendering performance and efficiency. Intended Audience: This presentation is targeting seasoned graphics developers. Experience with DirectX 12 and GCN is recommended, but not required.

In Phase One, we will cover the basics of using the Unity editor’s interface, customizing the workspace, building a 3D environment, and adding sound effects. In Phase Two, we will import a player character asset, learn about Animator Controllers, make animations, set up physics and gravity, and add player movement scripts. In Phase Three, we will set up our Camera and write a script to make the camera follow our player character.

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.

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.

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.

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?

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.

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?
