Rendering Technologies from Crysis 3 (GDC 2013)Tiago Sousa
This talk covers changes in CryENGINE 3 technology during 2012, with DX11 related topics such as moving to deferred rendering while maintaining backward compatibility on a multiplatform engine, massive vegetation rendering, MSAA support and how to deal with its common visual artifacts, among other topics.
Optimizing the Graphics Pipeline with Compute, GDC 2016Graham Wihlidal
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.

stackconf 2023 | Ceph for Public Cloud Workloads by Phil Williams.pdfNETWAYS
Public clouds were initially popularized under the premise that workloads are dynamic, and that you could easily match available compute resources to the peaks and troughs in your consumption, rather than having to maintain mostly idle buffer capacity to meet peak user demand. However, what has become more apparent is that this isn’t necessarily true when it comes to storage. Typically what is observed in production environments is a continual growth of all data sets, across those that are actively used for decision making or transactional processing, those maintained as training data for AI/ML, or kept for archival purposes, and simply just backups of critical data. During this talk we will discuss how Ceph can be deployed in a cost effective manner adjacent to public clouds, and investigate the financial implications of both approaches.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
The Art of the Pitch: WordPress Relationships and SalesLaura Byrne
Clients don’t know what they don’t know. What web solutions are right for them? How does WordPress come into the picture? How do you make sure you understand scope and timeline? What do you do if sometime changes?
All these questions and more will be explored as we talk about matching clients’ needs with what your agency offers without pulling teeth or pulling your hair out. Practical tips, and strategies for successful relationship building that leads to closing the deal.
The infamous Mallox is the digital Robin Hoods of our time, except they steal from everyone and give to themselves. Since mid-2021, they've been playing hide and seek with unsecured Microsoft SQL servers, encrypting data, and then graciously offering to give it back for a modest Bitcoin donation.
Mallox decided to go shopping for new malware toys, adding the Remcos RAT, BatCloak, and a sprinkle of Metasploit to their collection. They're now playing a game of "Catch me if you can" with antivirus software, using their FUD obfuscator packers to turn their ransomware into the digital equivalent of a ninja.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
