Node
Node.js is a platform that enables building real-time web applications using JavaScript. It allows for non-blocking I/O which makes it well-suited for real-time applications like Twitter and Facebook that deliver information to users as soon as it is published. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient for data-intensive real-time applications compared to other frameworks. Socket.IO is a library that simplifies real-time communication with WebSockets in Node.js applications.

AA261: DevOps lessons in collaborative maintenance
On January 31, 2000, Alaska Airlines Flight 261 plunged into the Pacific ocean in an extreme "nose down" position, killing all 88 crew and passengers on board. The NTSB concluded AA261's horizontal stabiliser trim system's jackscrew was inadequately maintained, causing the pilots to lose all control of the plane.
There are striking parallels with the problems we face daily in IT operations & software development, and the 30 years of give and take between the aircraft manufacturer's engineers, airline maintenance staff, and federal regulators that preceded AA261's simple mechanical failure.
In this talk, Lindsay looks at the complex interplay between the parties in the AA261 crash through a DevOps lens, investigating the collaborative approach to maintenance and operation of the MD-83 aircraft, and relating the complexities back to the complex IT systems we build and maintain.

Chris Jones, Director of Product Management at BrainChip , presents the “Temporal Event Neural Networks: A More Efficient Alternative to the Transformer” tutorial at the May 2024 Embedded Vision Summit.
The expansion of AI services necessitates enhanced computational capabilities on edge devices. Temporal Event Neural Networks (TENNs), developed by BrainChip, represent a novel and highly efficient state-space network. TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...
The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
