G1 Hardware 528 Mhz processor 192Mb RAM 256Mb ROM + 2Gb SD card wifi + 3G (not multi)touchscreen GPS accelerometer + compass keyboard

An aside: location-based AR wikitude, Google Sky Map, Gamaray, Layar

Interface menu button back button notification bar slidey drawer thing slidey homescreen with widgets context menu (press and hold)

That's great, but... sometimes confusing interface sometimes buggy (apps crash, caller-ID FAIL) poor battery life low internal memory on G1 means you can't install all the apps you want

Software stack It's Java... ...but not as you know it Custom 'JVM' - Dalvik Most of J2SE (minus GUI) Bundled libraries (android.*) for telephony, location, animation, OpenGL ES, SQLlite, etc. Apache XML libraries

Core Components Activities Intents Content Providers Services All provide the illusion of constantly running applications

Publishing your app Package as .apk file Install on any phone (with “untrusted apps”) Can publish to Marketplace for $25 joining fee Marketplace currently has 8000+ apps

Another aside: ASE Android Scripting Environment Program on your phone, in Python, Perlm JRuby, BeanShell, Lua... E.g. serve the contents of your SD card in 4 lines of Python:

Conclusions Modern, flexible development framework Open source Low barrier to entry - programming - publishing

New Ways to Reduce Database Costs with ScyllaDBScyllaDB

How ScyllaDB’s latest capabilities can reduce your infrastructure costs ScyllaDB has been obsessed with price-performance from day 1. Our core database is architected with low-level engineering optimizations that squeeze every ounce of power from the underlying infrastructure. And we just completed a multi-year effort to introduce a set of new capabilities for additional savings. Join this webinar to learn about these new capabilities: the underlying challenges we wanted to address, the workloads that will benefit most from each, and how to get started. We’ll cover ways to: - Avoid overprovisioning with “just-in-time” scaling - Safely operate at up to ~90% storage utilization - Cut network costs with new compression strategies and file-based streaming We’ll also highlight a “hidden gem” capability that lets you safely balance multiple workloads in a single cluster. To conclude, we will share the efficiency-focused capabilities on our short-term and long-term roadmaps.

LSNIF: Locally-Subdivided Neural Intersection FunctionTakahiro Harada

Neural representations have shown the potential to accelerate ray casting in a conventional ray-tracing-based rendering pipeline. We introduce a novel approach called Locally-Subdivided Neural Intersection Function (LSNIF) that replaces bottom-level BVHs used as traditional geometric representations with a neural network. Our method introduces a sparse hash grid encoding scheme incorporating geometry voxelization, a scene-agnostic training data collection, and a tailored loss function. It enables the network to output not only visibility but also hit-point information and material indices. LSNIF can be trained offline for a single object, allowing us to use LSNIF as a replacement for its corresponding BVH. With these designs, the network can handle hit-point queries from any arbitrary viewpoint, supporting all types of rays in the rendering pipeline. We demonstrate that LSNIF can render a variety of scenes, including real-world scenes designed for other path tracers, while achieving a memory footprint reduction of up to 106.2x compared to a compressed BVH. https://arxiv.org/abs/2504.21627

As organizations generate over 2 billion pieces of content daily in Microsoft 365, the need for robust data classification, sensitivity labeling, and Data Loss Prevention (DLP) has never been more urgent. This session addresses the growing challenge of managing unstructured data, with 73% of sensitive content remaining undiscovered and unclassified. Using a mountaineering metaphor, the speakers introduce the “Secure by Default” blueprint—a four-phase maturity model designed to help organizations scale their data security journey with confidence, clarity, and control. 🔐 Key Topics and Microsoft 365 Security Features Covered: Microsoft Purview Information Protection and DLP Sensitivity labels, auto-labeling, and adaptive protection Data discovery, classification, and content labeling DLP for both labeled and unlabeled content SharePoint Advanced Management for workspace governance Microsoft 365 compliance center best practices Real-world case study: reducing 42 sensitivity labels to 4 parent labels Empowering users through training, change management, and adoption strategies 🧭 The Secure by Default Path – Microsoft Purview Maturity Model: Foundational – Apply default sensitivity labels at content creation; train users to manage exceptions; implement DLP for labeled content. Managed – Focus on crown jewel data; use client-side auto-labeling; apply DLP to unlabeled content; enable adaptive protection. Optimized – Auto-label historical content; simulate and test policies; use advanced classifiers to identify sensitive data at scale. Strategic – Conduct operational reviews; identify new labeling scenarios; implement workspace governance using SharePoint Advanced Management. 🎒 Top Takeaways for Information Management Professionals: Start secure. Stay protected. Expand with purpose. Simplify your sensitivity label taxonomy for better adoption. Train your users—they are your first line of defense. Don’t wait for perfection—start small and iterate fast. Align your data protection strategy with business goals and regulatory requirements. 💡 Who Should Watch This Presentation? This session is ideal for compliance officers, IT administrators, records managers, data protection officers (DPOs), security architects, and Microsoft 365 governance leads. Whether you're in the public sector, financial services, healthcare, or education. 🔗 Read the blog: https://nikkichapple.com/irms-conference-2025/

Evaluation Challenges in Using Generative AI for Science & Technical ContentPaul Groth

Evaluation Challenges in Using Generative AI for Science & Technical Content. Foundation Models show impressive results in a wide-range of tasks on scientific and legal content from information extraction to question answering and even literature synthesis. However, standard evaluation approaches (e.g. comparing to ground truth) often don't seem to work. Qualitatively the results look great but quantitive scores do not align with these observations. In this talk, I discuss the challenges we've face in our lab in evaluation. I then outline potential routes forward.

Slides for my "Multistream support in the Janus SIP and NoSIP plugins" presentation at the OpenSIPS Summit 2025 event. They describe my efforts refactoring the Janus SIP and NoSIP plugins to allow for the gatewaying of an arbitrary number of audio/video streams per call (thus breaking the current 1-audio/1-video limitation), plus some additional considerations on what this could mean when dealing with application protocols negotiated via SIP as well.

Supercharge Your AI Development with Local LLMsFrancesco Corti

In today's AI development landscape, developers face significant challenges when building applications that leverage powerful large language models (LLMs) through SaaS platforms like ChatGPT, Gemini, and others. While these services offer impressive capabilities, they come with substantial costs that can quickly escalate especially during the development lifecycle. Additionally, the inherent latency of web-based APIs creates frustrating bottlenecks during the critical testing and iteration phases of development, slowing down innovation and frustrating developers. This talk will introduce the transformative approach of integrating local LLMs directly into their development environments. By bringing these models closer to where the code lives, developers can dramatically accelerate development lifecycles while maintaining complete control over model selection and configuration. This methodology effectively reduces costs to zero by eliminating dependency on pay-per-use SaaS services, while opening new possibilities for comprehensive integration testing, rapid prototyping, and specialized use cases.

Introduction to Android development

1. Programming Android for fun and profit

2. New kid on the smartphone block Source: http://www.appleinsider.com/articles/09/08/21/canalys_iphone_outsold_all_windows_mobile_phones_in_q2_2009.html

3. Handsets

4. G1 Hardware 528 Mhz processor 192Mb RAM 256Mb ROM + 2Gb SD card wifi + 3G (not multi)touchscreen GPS accelerometer + compass keyboard

5. An aside: location-based AR wikitude, Google Sky Map, Gamaray, Layar

6. Interface menu button back button notification bar slidey drawer thing slidey homescreen with widgets context menu (press and hold)

7. That's great, but... sometimes confusing interface sometimes buggy (apps crash, caller-ID FAIL) poor battery life low internal memory on G1 means you can't install all the apps you want

8. Software stack It's Java... ...but not as you know it Custom 'JVM' - Dalvik Most of J2SE (minus GUI) Bundled libraries (android.*) for telephony, location, animation, OpenGL ES, SQLlite, etc. Apache XML libraries

9. Core Components Activities Intents Content Providers Services All provide the illusion of constantly running applications

10. Enough talk, let's demo!

11. Publishing your app Package as .apk file Install on any phone (with “untrusted apps”) Can publish to Marketplace for $25 joining fee Marketplace currently has 8000+ apps

12. Another aside: ASE Android Scripting Environment Program on your phone, in Python, Perlm JRuby, BeanShell, Lua... E.g. serve the contents of your SD card in 4 lines of Python:

13. Conclusions Modern, flexible development framework Open source Low barrier to entry - programming - publishing

14.
