The Libre-SOC Project aims to create an entirely Libre-Licensed, transparently-developed fully auditable Hybrid 3D CPU-GPU-VPU, using the Supercomputer-class OpenPOWER ISA as the foundation.
Our first test ASIC is a 180nm "Fixed-Point" Power ISA v3.0B processor, 5.1mm x 5.9mm, as a proof-of-concept for the team, whose primary expertise is in Software Engineering. Software Engineering training brings a radically different approach to Hardware development: extensive unit tests, source code revision control, automated development tools are normal. Libre Project Management brings even more: bug trackers, mailing lists, auditable IRC logs and a wiki are standard fare for Libre Projects that are simply not normal Industry-Standard practice.
This talk therefore goes through the workflow, from the original HDL through to the GDS-II layout, showing how we were able to keep track of the development that led to the IMEC 180nm tape-out in July 2021. In particular, by following a parallel development process involving "Real" and "Symbolic" Cell Libraries, developed by Chips4Makers, will be shown how our developers did not need to sign a Foundry NDA, but were still able to work side-by-side with a University that did. With this parallel development process, the University upheld their NDA obligations, and Libre-SOC were simultaneously able to honour its Transparency Objectives.
This presentation covers various partners and collaborators who are currently working with OpenPOWER foundation ,Use cases of OpenPOWER systems in multiple Industries , OpenPOWER Workgroups and OpenCAPI features .
RISC-V growth and successes in technology and industry - embedded world 2021RISC-V International
RISC-V International has more than 1,000 members across over 50 countries who are working in hardware, software, services, and various industries for a strong and healthy RISC-V ecosystem. It is projected that by 2025 there will be over 62 billion RISC-V CPU cores and the total market for RISC-V IP and software is expected to grow to over $1b by 2025.
In 2020 alone, we saw successes with newly defined RISC-V accelerator architectures, affordable RISC-V open source small-board computers, development boards for personal computers, and an incredibly fast 64-bit RISC-V Core as the community also ratified key specifications and made advances in security.
As we see the growth of RISC-V into industries such as AI, machine learning, blockchain, 5G, medical, and industrial, we will see the ratifications of new extensions that enable this growth.
Join Kim McMahon, Director of Marketing and Stephano Cetola, Technical Program Manager as we take a look at where RISC-V is going in 2021.
Intel trusted execution environment, SGX, offers an attractive solution for protecting one's private data in the public cloud environment, even in the presence of a malicious OS or VMM.
In this talk, we will:
* explore how SGX mitigates various attack surfaces and the caveats of naively using the technology to protect applications,
* discuss the performance implications of SGX on common applications and understand the new bottlenecks created by SGX, which may lead to a 5X performance degradation.
* describe an optimized SGX interface, HotCalls, that provides a 13-27x speedup compared to the built-in mechanism supplied by the SGX SDK.
* discuss how it is possible for the OS to manage secure memory without having access to it.
* explore various attack surfaces and published attacks which require collusion with the OS. Specifically, page-fault and page-fault-less “controlled channel attacks”, branch-shadowing attacks and potential mitigations.

IPSN 2009 tutorial: http://ipsn.acm.org/2009/tutorials.htm
Title: IP-based Sensor Networks: a Hands-on Tutorial (uIP)
Speakers: Adam Dunkels, Fredrik Osterlind, Nicolas Tsiftes (SICS)
Time: April 16,2009 Thursday 3:00PM~5:00PM
IP-based sensor networks are a rapidly emerging hot topic in both academia and the industry.
The open source uIP stack from the Contiki operating system, first released in 2001, is used in IP-enabled products and systems from hundreds of companies, ranging from pico-satellites, airplanes, and car engines, to worldwide freighter container tracking systems, ship control systems, and oil boring and pipeline monitoring systems. In October 2008 Cisco Systems released uIPv6, the world's smallest fully compliant IPv6 stack, for Contiki.
During this tutorial, participants will get started with building IP-based sensor networks with Contiki and uIP, and get hands-on experience with developing, compiling, and running IP-based software on sensornet hardware, setting up IP networking to the sensor network, and getting performance metrics (power, throughput, latency) from a running network.
We use a combination of Tmote Sky and Sentilla JCreate motes as the hardware platform. We provide Tmote Skys and JCreates for participants to borrow during the tutorial.
To avoid installation of compilers and tools, participants will use the Instant Contiki development environment, a complete development environment in a single-file download consisting of a VMWare virtual machine with all Contiki software development tools installed: http://www.sics.se/contiki/instant-contiki.html
The objective of this conference is to explain how to develop on small machines that can boot fast, fanless … It’s convenient and often more realistic than to work in virtual machines, especially when working on developping drivers.
Willy will list all the necessary items to setup an optimal environment to be as efficient as possible. Among these one: the importance of investing time to speed up the boot, etc …
He will also speak a bit about crosstool-ng, used in this environement.

This short slide deck summarizes the motivation behind investing in memory forensics, the options we considered and tech stack we're using to acquire memory of an EC2 instance, and our approach to memory analysis.
Docker microservices and the service meshDocker, Inc.
The nature of containerized, cloud-native applications is rapidly advancing with a fundamentally different architecture that will rely on service meshes with smarter proxies, traffic management, and enhanced observability for cooperating microservices, serverless functions, and complex workflows. In this session we will highlight the features that characterize this architectural transformation in the Docker cloud-native ecosystem.

An embedded system employs a combination of hardware & software to perform a specific function; is part of a larger system that may not be a "computer"; works in a reactive and time-constrained environment. In other words, embedded system is defined as any device that includes a programmable computer but is not itself intended to be a general-purpose computer. The key characteristic is being dedicated to handle a particular task.
Software-Infrastrukturen modernisieren in der Produktion - Digitale Transform...Dominik Obermaier
[GERMAN]
Welche Probleme tauchen bei der Modernisierung von Software-Infrastrukturen in der Fertigungsindustrie auf, wie sehen gängige Architekturmuster moderner Fabriken aus und wie kann MQTT & Sparkplug helfen, operative Technik und IT-Systeme zu verbinden?
Die digitale Transformation hat längst die Produktionshallen erreicht und verspricht revolutionäre Möglichkeiten in der Fertigung. Industrie 4.0 vernetzt alle am Produktionsprozess beteiligten Systeme. Damit steigt die Bedeutung von Standards, die einen systemübergreifenden Datenaustausch und eine reibungslose Maschine-zu-Maschine-Kommunikation gewährleisten.
In diesem Webinar werden die Probleme bei der Modernisierung von Software-Infrastrukturen in der Produktionsumgebung erörtert. Es werden gängige Architekturmuster vorgestellt, die moderne Fabriken verwenden, um die digitale Transformation in der Fabrik zu ermöglichen. MQTT wird dabei als Protokoll für die Verbindung von operativer Technik (OT-Systemen) und IT-Systemen verwendet. Außerdem wird die neue Sparkplug-Spezifikation vorgestellt, die Plug-and-Play-Interoperabilität zwischen IoT-Geräten und IoT-Anwendungen ermöglicht.
Erfahren Sie in dieser Webinaraufzeichnung:
Wie Automatisierungsdaten mit industriellen Messaging-Protokollen integriert werden,
Wie MQTT in einer unternehmenskritischen Echtzeitumgebung eingesetzt wird,
Wie Sie einen MQTT-Broker in der Cloud oder “on-premise” einsetzen und OT-Daten mit industriellen und business Anwendungen verbinden,
Wie Sparkplug die Datensilos in Ihrer Organisation aufbrechen und eine “Single Source of Truth” bereitstellen kann, die neue Anwendungen, wie Machine-Learning und KI, ermöglicht.

Internet of Things is going to be big. Billions of connected devices and trillions of dollars of the economic value-add in the 2020. The existing enterprises are going to start collecting the enormous volume of data from the myriad of the heterogeneous devices. Data collected by the enterprises will be used to transform these organizations to be more efficient.
What does it mean for an average back-end developer hired in organization willing to adopt to the Internet of Things world? What should the developers know to stay relevant in the 2020? Which part of the existing knowledge and know-how can be reused? What new the developers have to to learn and master to be able to create the IoT-ready systems?
Are you back-end developer? Do you hire or manage developers? Then come, listen to my talk and learn what Internet of Things means for the developers and companies hiring them.
Today, the boundaries between the general purpose PCs, the servers and the embedded systems are more blurred. These computers are sharing same platforms, same peripherals. For example, an x86/Mac PC can be used as a server, an x86/PowerPC CPU can be used in an embedded system like portable navigation device (PND). On the other way, the popular embedded processor StrongARM was a powerful desktop PC processor for the DEC workstation, and the embedded systems often also act servers, like NAS (Network Attached Storage). As same as the hardware suppliers, the OS suppliers port their products into the desktop PCs, servers and embedded systems.
Webinar: OpenEBS - Still Free and now FASTEST Kubernetes storageMayaData Inc
Webinar Session - https://youtu.be/_5MfGMf8PG4
In this webinar, we share how the Container Attached Storage pattern makes performance tuning more tractable, by giving each workload its own storage system, thereby decreasing the variables needed to understand and tune performance.
We then introduce MayaStor, a breakthrough in the use of containers and Kubernetes as a data plane. MayaStor is the first containerized data engine available that delivers near the theoretical maximum performance of underlying systems. MayaStor performance scales with the underlying hardware and has been shown, for example, to deliver in excess of 10 million IOPS in a particular environment.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

2. Oxide?
● New computer company seeking to modernize on-premises computers
● We are rethinking the embedded systems at the foundation of
computers: the hardware root-of-trust and service processor
● With its emphasis on safety, security, and size, Rust is an excellent fit for
these applications
3. Tock
● Tock is a Rust-based operating system designed for embedded systems
● A logical descendent of TinyOS, retains the emphasis on small size while
allowing the system to be extensible, portable and reliable
● Tock allows for MPU-/PMP-protected applications
● Importantly, Tock aims for application portability
● As such, promising for collaboration across different embedded
projects -- and being used for the OpenTitan root-of-trust project
4. Verilator + Ibex
● Verilator is an open source, cycle-accurate simulation tool that takes
synthesizable Verilog, and translates it to C++ to execute
● Verilator can emit e.g. FST for use as input to GTKwave
● Verilator is being used to simulate Ibex, an open 32-bit RISC-V core
● Ibex is the softcore for Earl Grey, the first OpenTitan SoC
● Ibex has a tracer module that has been modified to support Verilator
with human-readable instruction logging
5. Complete instruction tracing!
● Debugging embedded systems is extraordinarily excruciating...
● ...but having entire instruction traces is singularly valuable!
● Looking at instruction traces can enable bringup -- and obviously has
tremendous power around code coverage, memory coverage, etc.
● Challenge: as tedious as instruction traces are to use to understand
C-based systems, they are much, much harder for Rust-based systems!
● Can we process Ibex Verilator traces to make sense of Tock?
6. Tockilator
● Rust program that takes an Ibex Verilator trace and a pointer to the ELF
objects representing the boot ROM and Tock instance
● Symbolically resolves instructions; by determining function entry and
return, can show execution flow through Tock
● Tockilator uses DWARF information to decode function parameters
and (importantly!) inlined function calls
● Tock architecture allows Tockilator to show app + kernel flow
● Primordial, but promising for Tock and Tock-based applications!
7. Rust, Tockilator and beyond
● Rust is an excellent fit for embedded systems: its ability to have
powerful abstractions with tiny binaries borders on the magical
● But to debug systems, we must cut through the magic, allowing the
system to be understood from the machine up
● Tockilator is one approach, but there is much more than can be done;
instruction traces are a very rich vein for system understanding!
● Tockilator is available at https://github.com/oxidecomputer/tockilator
