WebRTC Webinar & Q&A - Sumilcast Standards & Implementation
WebRTC webinar talking about the status of Simulcast in the standards and browser implementations. We also explain what simulcast is, the use cases and what simulcast isn't. Webinar is part of the monthly WebRTC live Q&A sessions by Alex Gouailard, Dan Burnett and Amir Zmora
Codetainer: a Docker-based browser code 'sandbox'
Codetainer is a browser-based sandbox for running Docker containers. It allows users to "try 'X' in your browser" for any X by running Docker containers in an isolated and programmable manner directly in the browser. Codetainer uses Docker APIs to launch and manage lightweight containers via a Go-based API server. Users can create and register Docker images, launch "codetainers" from those images, and interact with the codetainers through the browser via websockets, viewing terminals and sending keystrokes. Codetainer aims to provide a secure and flexible environment for use cases like tutorials, training, and remote management while addressing challenges around container introspection and security.
Springboard & OpenCV

Analyzing the Performance of Mobile Web
This document discusses techniques for analyzing the performance of mobile web applications. It covers challenges like network variability, different device hardware, and continuous integration. Approaches mentioned include benchmarking, injecting instrumentation, emulation, and remote inspection. Strategies suggested are reducing complexity, replicating analysis on desktop, and tweaking at the system level. Tools mentioned include the Nexus One, Gingerbread, PhantomJS, and headless WebKit. The document provides examples and caveats for analyzing areas like network traffic, graphics commands, garbage collection, and JavaScript parsing.
Swift Install Workshop - OpenStack Conference Spring 2012
OpenStack Swift is a highly-available distributed object storage
system which supports highly concurrent workloads. Swift is the
backbone behind Cloud Files, Rackspace's storage-as-a-service
offering.
In this workshop, which will be hosted by members of SwiftStack, Inc.,
we'll walk you through deployment and use of OpenStack Swift. We'll
begin by showing you how to install Swift from the ground up.
You'll learn:
- what you should know about Swift's architecture
- how to bootstrap a basic Swift installation
After that, we'll cover how to use Swift, including information on:
- creating accounts and users
- adding, removing, and managing data
- building applications on top of Swift
Bring your laptop (with virutalization extensions enabled in the BIOS)
and we will walk through setting up Swift in a virtual machine. We'll
also build an entire application on top of Swift to illustrate how to
use Swift as a storage service. This is a workshop you won't want to
miss!
An Introduction to Twisted
This document provides an introduction to Twisted, an event-driven networking engine written in Python. It describes Twisted's key components, including the Reactor event loop, Deferred asynchronous programming abstraction, networking abstractions like Transport and Protocol, and high-level APIs for applications like HTTP, SMTP, FTP and more. It also discusses how to deploy Twisted applications using the twistd utility and provides additional resources for learning more about asynchronous programming and Twisted.
44CON 2014 - Stupid PCIe Tricks, Joe Fitzpatrick
Joe FitzPatrick gave a presentation on exploiting PCIe (Peripheral Component Interconnect Express) buses for hardware attacks. He discussed using DMA (direct memory access) over PCIe to read and write system memory, modify firmware, and potentially bypass mitigations like IOMMU (input-output memory management unit). FitzPatrick demonstrated proof-of-concept attacks on Macs and Windows PCs using custom PCIe devices and software. However, he noted that fully bypassing protections like VT-d on Macbooks had not yet been achieved and more work is needed to build attacks without imitating a genuine device.

Android RenderScript on LLVM
The document discusses RenderScript on LLVM. It describes RenderScript as a way to perform 3D rendering and compute tasks portably and with high performance on Android. It outlines the main components: an offline compiler that optimizes scripts, an online JIT compiler, and a runtime library. It provides an example of using RenderScript to convert an image to grayscale and discusses how scripts are compiled and executed to provide fast launch times.
Track c-High speed transaction-based hw-sw coverification -eve
The document discusses transaction-based hardware-software co-verification using emulation. It describes how traditional cycle-based co-verification is slow due to communication overhead between the testbench and emulator. Transaction-based co-verification improves speed by only synchronizing when required and allowing parallel execution. Transactors are used to convert high-level commands from the testbench to a bit-level protocol for the emulator. This allows emulation speeds of tens of MHz, orders of magnitude faster than cycle-based. An example transactor for a virtual memory is presented.
[1C2]webrtc 개발, 현재와 미래
This document discusses WebRTC development for both current and future applications. It provides an overview of WebRTC fundamentals including protocols like ICE, STUN, TURN, SDP, DTLS and SRTP. It also discusses building WebRTC services and considerations for quality and performance when developing real-time video applications using WebRTC.

Project ACRN hypervisor introduction
The document discusses ACRN, an open-source lightweight hypervisor intended for consolidating heterogeneous workloads and streamlining IoT edge development. It provides an overview of ACRN's architecture and key modules, including boot process, CPU virtualization, memory management, interrupt handling, pass-through devices, and device model for handling I/O requests. The document also outlines enhancements in ACRN 2.0, such as supporting new operating systems and safety/real-time virtual machines.
How to write clean & testable code without losing your mind
If you create software that is to be developed continuously over several years you'll need a sustainable approach to code quality.
In our early days of AEM development, however, we used to struggle with code that is rigid, hard to test and full of LOG.debug calls.
In this talk I will share some development best practices we have found that really work in actual AEM based software, e.g. to achieve 100% code coverage and provide high confidence in the code base.
Spoiler alert: no new libraries, frameworks or tools are required - once you know the ideas, plain old TDD and the S.O.L.I.D. principles of Clean Code will do the trick.

★ Session Summary ★
One of the important technical novelties introduced with the recent release of Android Lollipop is the replacement of Dalvik, the VM which was used to execute the bytecode produced from Java apps, with ART, a new Android Run-Time. One interesting aspect in this upgrade is that the use of Just-In-Time compilation was abandoned in favour of Ahead-Of-Time compilation. This delivers better performance [1], also leaving a good margin for future improvements. ART was designed to support multiple compilers. The compiler that shipped with Android Lollipop is called the “Quick Compiler”. This is simple, fast, and is derived from Dalvik’s JIT compiler. In 2014 our team at ARM worked in collaboration with Google to extend ART and its Quick Compiler to add support for 64-bit and for the A64 instruction set. These efforts culminated with the recent release of the Nexus 9 tablet, the first 64-bit Android product to hit the market. Despite Google’s intention of replacing the Quick Compiler with the so-called “Optimizing Compiler”, the job for the the Quick Compiler is not yet over. Indeed, the Quick Compiler will remain the only usable compiler in Android Lollipop. Therefore, all competing parties in the Android ecosystem have a huge interest in investigating and improving this component, which will very likely be one of the battlegrounds in the Android benchmark wars of 2015. This talk aims to give an unofficial overview of ART’s Quick compiler. It will first focus on the internal organisation of the compiler, adopting the point of view of a developer who is interested in understanding its limitations and strengths. The talk will then move to exploring the output produced by the compiler, discussing possible strategies for improving the generated code, while keeping in mind that this component may have a limited life-span, and that any long-term work would be better directed towards the Optimizing Compiler.

OOPSLA Talk on Preon
Preon is a declarative data binding framework for Java that allows mapping data structures to binary encoded representations. It generates decoders, encoders, and documentation automatically based on annotations on the data structure classes. This avoids the need for manual parsing of bit streams and improves maintainability. Preon uses a chain of Codec objects to handle each encoding/decoding task, keeping the logic encapsulated and modular. It supports features like expressions, lazy loading, inheritance and custom CodecFactories to handle different data types. The goal is to hide the complexity of binary encoding and make working with binary data as easy as working with regular Java objects.
Seaside Portability
Seaside is a rare example of software that runs on all the major current Smalltalk platforms: Pharo, Gemstone, GNU Smalltalk, Squeak, VA Smalltalk, and VisualWorks. This presentation to the NYC Smalltalk users group looks at some of the tools and techniques the Seaside team uses to make life as easy as possible for the frameworks porters.

[DockerCon 2023] Reproducible builds with BuildKit for software supply chain ...
Images maintained by a reputable organization or an individual are often considered to be trustworthy; however, it is hard to deny the possibility that they might have silently injected malicious codes that are not present in the source repo. Also, even if they have no malicious intent, their images can still be compromised on an accidental leakage of registry credentials.
The latest release of BuildKit solves this supply chain security concern with reproducible builds. Reproducible builds is a technique to ensure that a bit-for-bit identical image can be reproduced from its source code, by anybody, at any time. When multiple actors can attest to an image's reproducibility, it signifies that the image contains no code of a secret origin.
Audiences of this talk will learn how they can and how sometimes they cannot make their images reproducible to improve their trust.
Docker meetup-20-apr-17-openshit
This document provides an agenda and overview of a Docker Meetup on April 20, 2017 about using Openshift for production deployments. The agenda includes introductions to containers, Docker, Kubernetes, and Openshift, as well as demonstrations of Openshift installation, Docker orchestration using Openshift, auto-scaling with Openshift, source-to-image deployments, and CI/CD pipelines. It also includes brief introductions to container and Docker technologies, and how Kubernetes addresses problems with scheduling, lifecycles, discovery, monitoring, authentication, and scaling of containers.
Parsing and Type checking all 2^10000 configurations of the Linux kernel
In many projects, lexical preprocessors are used to manage different configurations of the project with conditional compilation. Unfortunately, while being a simple way to implement variability, conditional compilation and lexical preprocessor macros hinder automatic analysis, even though such analysis is urgently needed to combat variability-induced complexity. To analyze code with its variability, we need to parse it without preprocessing it. However, current parsing solutions use unsound heuristics, support only a subset of the language, or suffer from exponential explosion. We introduce a novel variability-aware parser that can parse unpreprocessed code without heuristics. On top of parsing, which detects syntax errors in all configurations, we have constructed a variability-aware type system and module system that additionally detect other compiler-time errors. With this infrastructure, we are in the process of checking the entire Linux kernel with 10000 compile-time configuration options and, hence, up to 2^10000 configurations for syntax and type errors.
Simplify Networking for Containers
Presentation given at the 2017 LinuxCon China
With the booming of Container technology, it brings obvious advantages for cloud: simple and faster deployment, portability and lightweight cost. But the networking challenges are significant. Users need to restructure their network and support container deployment with current cloud framework, like container and VMs.
In this presentation, we will introduce new container networking solution, which provides one management framework to work with different network componenets through Open/friendly modelling mechnism. iCAN can simplify network deployment and management with most orchestration systems and a variety of data plane components, and design extendsible architect to define and validate Service Level Agreement(SLA) for cloud native applications, which is important factor for enterprise to deliver successful and stable service via containers.
Building a modern SaaS in 2020
Building a modern Software as a Service platform brings a lot of interesting engineering challenges. During this talk, I’m going to share my team’s journey of building a SaaS from scratch in 2020. First, we are going to start with the technologies and the architecture we picked. Then, we’ll go over the interesting challenge of implementing multitenancy. And we'll see how we benchmarked three different options and picked one. And last but not least, we’ll explore how every startup can use open source technologies to build observability infrastructure. And how to run their SaaS in production.
NetDevOps Developer Environments with Vagrant @ SCALE16x

Sustainable Futures: Funding the Web Ecosystem
We work and live in the modern world. Surely such an integral piece of our
day-to-day life is being built and maintained in a way that ensures it will
last?
Unfortunately this isn’t the case. The current system funding access to the web
is fragile, fractured and unsustainable. In this talk, I’ll give an overview of
the current state of things, how we currently fund the web, why this is a
problem, and possible ways to fix this so that access to information remains
stable and sustainable for future generations to come.

[DockerCon 2023] Reproducible builds with BuildKit for software supply chain ...
Images maintained by a reputable organization or an individual are often considered to be trustworthy; however, it is hard to deny the possibility that they might have silently injected malicious codes that are not present in the source repo. Also, even if they have no malicious intent, their images can still be compromised on an accidental leakage of registry credentials.
The latest release of BuildKit solves this supply chain security concern with reproducible builds. Reproducible builds is a technique to ensure that a bit-for-bit identical image can be reproduced from its source code, by anybody, at any time. When multiple actors can attest to an image's reproducibility, it signifies that the image contains no code of a secret origin.
Audiences of this talk will learn how they can and how sometimes they cannot make their images reproducible to improve their trust.
Docker meetup-20-apr-17-openshit
This document provides an agenda and overview of a Docker Meetup on April 20, 2017 about using Openshift for production deployments. The agenda includes introductions to containers, Docker, Kubernetes, and Openshift, as well as demonstrations of Openshift installation, Docker orchestration using Openshift, auto-scaling with Openshift, source-to-image deployments, and CI/CD pipelines. It also includes brief introductions to container and Docker technologies, and how Kubernetes addresses problems with scheduling, lifecycles, discovery, monitoring, authentication, and scaling of containers.
Parsing and Type checking all 2^10000 configurations of the Linux kernel
In many projects, lexical preprocessors are used to manage different configurations of the project with conditional compilation. Unfortunately, while being a simple way to implement variability, conditional compilation and lexical preprocessor macros hinder automatic analysis, even though such analysis is urgently needed to combat variability-induced complexity. To analyze code with its variability, we need to parse it without preprocessing it. However, current parsing solutions use unsound heuristics, support only a subset of the language, or suffer from exponential explosion. We introduce a novel variability-aware parser that can parse unpreprocessed code without heuristics. On top of parsing, which detects syntax errors in all configurations, we have constructed a variability-aware type system and module system that additionally detect other compiler-time errors. With this infrastructure, we are in the process of checking the entire Linux kernel with 10000 compile-time configuration options and, hence, up to 2^10000 configurations for syntax and type errors.
Simplify Networking for Containers
Presentation given at the 2017 LinuxCon China
With the booming of Container technology, it brings obvious advantages for cloud: simple and faster deployment, portability and lightweight cost. But the networking challenges are significant. Users need to restructure their network and support container deployment with current cloud framework, like container and VMs.
In this presentation, we will introduce new container networking solution, which provides one management framework to work with different network componenets through Open/friendly modelling mechnism. iCAN can simplify network deployment and management with most orchestration systems and a variety of data plane components, and design extendsible architect to define and validate Service Level Agreement(SLA) for cloud native applications, which is important factor for enterprise to deliver successful and stable service via containers.
Building a modern SaaS in 2020
Building a modern Software as a Service platform brings a lot of interesting engineering challenges. During this talk, I’m going to share my team’s journey of building a SaaS from scratch in 2020. First, we are going to start with the technologies and the architecture we picked. Then, we’ll go over the interesting challenge of implementing multitenancy. And we'll see how we benchmarked three different options and picked one. And last but not least, we’ll explore how every startup can use open source technologies to build observability infrastructure. And how to run their SaaS in production.

A Year of the Servo Reboot: Where Are We Now?
Created by Mozilla Research in 2012 and now part of Linux Foundation Europe, the Servo project is an experimental rendering engine written in Rust. It combines memory safety and concurrency to create an independent, modular, and embeddable rendering engine that adheres to web standards. Stewardship of Servo moved from Mozilla Research to the Linux Foundation in 2020, where its mission remains unchanged. After some slow years, in 2023 there has been renewed activity on the project, with a roadmap now focused on improving the engine’s CSS 2 conformance, exploring Android support, and making Servo a practical embeddable rendering engine. In this presentation, Rakhi Sharma reviews the status of the project, our recent developments in 2023, our collaboration with Tauri to make Servo an easy-to-use embeddable rendering engine, and our plans for the future to make Servo an alternative web rendering engine for the embedded devices industry.

Building End-user Applications on Embedded Devices with WPE
The Web engine is the most important component of a Web Browser, enabling
developers to harness the power of the Web Platform to build their
applications. However, Web Browsers are not the only type of applications that
can be built with Web Engines, which can also be used to develop other types of
applications using the same Web-based technologies, but for a different type of
use cases other than "browsing the Web".
These use cases can cover a wide range of situations outside of the traditional
desktop or mobile environments, such as the ones embedded systems are usually
used for (e.g. set-top-boxes, smart home appliances, GPS navigation devices, or
in-car/in-flight infotainment systems, to name a few). And in those situations
it is very common to be running on boards with SoCs and a particular set of HW
capabilities that make it crucial for the Web Engine to be able to tightly
integrate with them.
In this session we will focus on how WPE, a fully Open Source port of the
WebKit Web engine for Linux-based embedded devices, can be used to adapt to the
different challenges that embedded devices pose to develop end-user
applications, using the power of the Web Platform underneath.

Automated Testing for Web-based Systems on Embedded Devices
Every day, embedded devices are becoming more powerful and capable of running
more elaborate applications. Among these applications are Web-based ones,
enabling to leverage features from the Web APIs to the embedded context, either
through a generic browser running a traditional Web application or through a
customized Web engine tightly integrated within the system.
But such capabilities usually bring new challenges, like testing user
interactions with the application using the embedded device's specific I/O
methods, such as gestures, or inspecting Web application internals with
JavaScript. In this context, using a browser automation framework such as
WebDriver, which is a W3C standard supported by WebKit Web engine, allows
testing Web-based applications on such devices as if the user were actually
using it, alongside running custom JS code.
In this session, we will cover why we need browser automation for testing on
certain types of embedded devices, with a focus on WebDriver as the proposed
tool to achieve that goal. We will also discuss WebDriver's main features and
limitations, as well as other possible approaches and frameworks that could be
considered for this kind of task.

Embedding WPE WebKit - from Bring-up to Maintenance
Embedded devices have become powerful enough to run Web content a decade ago,
and any modern SoC that can run Linux and includes a GPU is a potential
candidate to hide a Web engine under the surface. How did it made it there?
Does it only show Web content? What else can it do? The talk will cover
bring-up tips to build and get WPE WebKit working on your custom embedded
device and make your own simple Web browser, as well as the best practices for
keeping the system up to date. No less important is integration with the rest
of the system: this session will detail the possibilities that WebKit brings to
the table, including how to add new JavaScript APIs which call into native code
to provide tight, performant access to platform functionality.

Optimizing Scheduler for Linux Gaming.pdf
This talk dives into how the scheduler impacts your gameplay on Linux and
unveils our journey to smoother gameplay. How does task scheduling impact Linux
gaming? Suboptimal task scheduling can cause stuttering while playing games on
the Steam Deck game console. First, we nail down the enemy. What exactly is
"stuttering," and how can we measure its impact on your gameplay? Next, we
extensively analyzed the characteristics of game tasks from the scheduler’s
point of view. Characterizing task behavior in Linux gaming helps to understand
why some schedulers create much stuttering and others create less and to unveil
the secrets behind smooth vs. choppy performance. Lastly, we will share our
progress on the optimized scheduler for reducing the stuttering problems in
Linux gaming, especially Steam Deck. We implemented the scheduling policy based
on sched_ext, a BPF-based extensible scheduling framework.

Running JS via WASM faster with JIT
So, we are adding a backend for the SpiderMonkey’s codegen to enable JIT
support for JavaScript running through Wasm. Sounds a bit cryptic so let’s
divide it into parts.
SpiderMonkey is a JavaScript engine which is used for running JavaScript inside
the Firefox browser. SpiderMonkey is written in C++ and supports compilation
into the Wasm module, see live demo -
https://mozilla-spidermonkey.github.io/sm-wasi-demo/. However, SpiderMonkey
compiled into the Wasm module supports execution of JavaScript only in the
interpreter-only mode and it doesn’t support just-in-time compilation because
there is no Wasm backend for that. There are backends for Arm, X86, X64 etc but
there is none for Wasm.
Why do we want to add support for JIT? Well, because we want speed. Right now
there is no solution to run JS scripts via Wasm fast, there are only
interpreters.
Why does JIT improve performance?
The reasons are the same for why an interpreter is slower than a compiler -
because it eliminates the interpreter loop, uses a more efficient ABI and, more
importantly, it can specialize polymorphic operations in JavaScript. So, we not
only enable the JIT tier in SpiderMonkey for Wasm but we also provide support
for inline caches.
Inline caches is a mechanism for specializing the behavior of particular
operations like plus or a call to specific arguments provided at runtime.
With all that we can generate Wasm modules on the fly, instantiate them, and
link them to provide from ~2x to ~11x speedup over the interpreter. In the
talks we will cover how the whole scheme works with SpiderMonkey: 1. How to
link modules on the fly into SpiderMonkey.wasm 2. How to add an exotic Wasm
backend into SpiderMonkey’s supported backend line - X64, X86, Arm, Wasm 3. How
to use the whole solution in the cloud instead of QuickJS 4. How to get a
speedup of your JS over wasm with test data.

To crash or not to crash: if you do, at least recover fast!
What could be possibly worse that an almost unbeatable boss in
a game or a tough maze that consume hours of gameplay with not
much progress? How about a Linux kernel crash that makes you
lose all the game progress with no apparent reason or feedback?
Though rare, it is a real possibility that would make gamers
quite annoyed, given that Linux is used more and more as a
platform for playing games.
Some technologies are available to collect logs and feedback
the user in case such disastrous events happen, mostly related
with kernel crashes handling mechanisms. The main ones available
are kdump and pstore, but still there are work to be done in
this area...
In this talk we're going to present the basics about kernel
crash handling, like how a kernel panic might happen, how to
deal with that (with an overall discussion about kdump and
pstore techs) and the kdumpst tool, developed specially to
deal with this situation on Steam Deck (and generically on
Arch Linux); also we're gonna discuss some missing
pieces / ideas to make it even less likely gamers need to
complain that their device just got hang for no reason!

2023 in Chimera Linux
Chimera Linux is a novel Linux distribution built around FreeBSD core tools and
the LLVM toolchain. Since its initial launch in 2021, it has made a lot of
progress and is now in alpha stage. The system can be deployed on a wide array
of hardware and many people are using it as their desktop system; it works on
x86_64, AArch64, POWER (little and big endian) as well as RISC-V and by now
comes with thousands of packages.
While trying to be practical, Chimera is also highly hardened, partly thanks to
the LLVM toolchain, rendering it immune to various security issues other
distros are vulnerable to. It has transparent and robust infrastructure,
ensuring smooth deployment of packages. We are also developing various new
tooling that the whole ecosystem can benefit from, including the Turnstile
session tracker. Service management is based around Dinit, a modern,
supervising system; we maintain and create a variety of tooling around it,
trying to break the existing status quo with systemd, while abandoning legacy
approaches.
2023 has seen several major milestones, so I will focus on these, while also
giving a short overview so that people unfamiliar with the system don't feel
lost. I will also explain how our work benefits the entire Linux ecosystem, as
well as beyond.

Building a Linux distro with LLVM
For the last 3 years, I've been building a complete Linux distribution, Chimera
Linux (https://chimera-linux.org) using solely LLVM as its system toolchain -
that means Clang, compiler-rt, and libc++, alongside its other tooling. Right
now, it is a complete desktop system that is already used by many, with a
familiar GNOME interface and thousands of packages, targeting 5 CPU
architectures. In this talk I would like to focus on my experiences using the
toolchain, what obstacles got in the way, how I dealt with them, the issues
that are still left and I would like to see addressed, the many benefits using
LLVM gave the project, and overall give the audience an insight into practical
deployment of LLVM in a project where it isn't simply a drop-in alternative to
GCC.

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

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.

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.Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
