Should we really be trying to make our tech indistinguishable from magic? Is there dark magic in tech? And what does that have to do with a teleporting duck in a classroom?! We often hold creating 'a magical experience' as a key goal for design - it's fun, engaging, sometimes even playful, and it makes complex things look simple. But technological magic has a dark side too, especially when trying to help people learn and feel confident about technology. By its nature, magic you experience is not under your control: it's a trick, and you're not supposed to be able to understand it; magic is inscrutable, and for many, that's disempowering. In designing the BBC micro:bit and surrounding tools, we've thought a lot about the balance between the positive and the negative sides of creating of a magical experience. This talk will reflect on our struggle to balance technical authenticity and honesty with the need to provide a high quality experience that excites and inspires students. It will explain how we attempt to present simple, understandable analogs of more complicated, magical technology in order to help students gain a sense confidence with the tech around them. However, it will also look at how we've resorted to using our own bits of (nearly) invisible magic to make this all work nicely in a classroom. Through this discussion we'll look in detail at the presentation of the micro:bit's IO, the way the micro:bit's USB interface works, the microphone privacy LED, the web-based compiler and the simple radio communication. Finally, I will look beyond micro:bit at how using this concept of balancing transparency and magic can help us build better, more trustworthy tech. about this event: https://c3voc.de

In 1939 World War 2 started and the British Council—Britain's shiny new organisation for overseas cultural relations and propaganda—inherited the suddenly-closed tourist board's film-making department. Tourism films are no use in a war, so the Council turned their topics towards more cultural content as a softer kind of propaganda. Thus began a decade of film production that would have phenomenal overseas impact but be almost totally forgotten in Britain. Between 1940–1950, the British Council produced over 120 short documentary-style films about life in Britain covering sports, manufacturing, landscapes, art, architecture, public healthcare, the justice system, democratic process, public institutions like the National Trust and the BBC, and more besides. A far cry from the Ministry of Information's rigid style, this collection features some of the earliest works by winning cinematographers Geoffrey Unsworth (2001: A Space Odyssey, Cabaret, Superman), and Jack Cardiff (A Matter of Life and Death, Black Narcissus, The Red Shoes). Distributed to over 100 countries worldwide, the films are stunning, dated, funny, and bizarre by turn. They depict beautiful countrysides, optimistic cities, strong industry, forward-thinking social structures, and hardworking, happy people. They depict exactly the popular image of 1940s Britain that persists to this day... That may not be a coincidence. In this talk I'll cover the history and development of this film collection, how it was shaped, who saw the films, their staggering success, and their untold global legacy. about this event: https://c3voc.de

Sound effects are often heard but not explored. In this talk I will explain what goes into the process of creating video game sound effects, the way they impact a scene and how the smallest changes can make a massive difference to video games. Join me as I show you how I create sounds for video games, why sound matters and helps players immerse themselves into the game's story and world. about this event: https://c3voc.de

I'm an artist creating interactive installations. The hardest part is devising open-ended interaction, spaces that invite people to reveal their authentic selves, and to connect with those around. But trends in technology have gone in the opposite direction. Whether it's for usability, profit, safety, profit or 'sparking joy', or profit (it's usually profit), 'User Experience Design' was the flavour of the 2010s. Human-Computer Interaction has become a very planned affair. And the more planned it gets, the less room there is for the ambiguous messy bits that make us human. Could it be another way? Presenting... ✯✯✯ Rewilding Human-Computer Interaction ✯✯✯ where, instead of designing micromanaged user experiences, we create open-ended spaces that embrace the unknown, the messy and the human. The ills of the online world are not problems inherent to its users but to systems that prevent those users from existing fully as humans. The solution is not more design, but more wildness. Soapbox aside, I do have a speculative project to share on this front. In a collaboration with artist/AI researcher Panagiotis Tigas, we've been training Variational Autoencoders on improvised dance, and from these devising personalised interfaces that respond to creative movement. The resulting system allows you to move through a 16-dimensional parameter space while following the intuitions of the body. As an entangled black box system, I can't explain how to use it, but it can be learnt by the body through exploration and play. We have it here at EMF as in Latent Voyage, letting you navigate the hallucinatory latent space of an image generating AI. about this event: https://c3voc.de

Every year we collect more data than before, and the tools we use to manage that data are evolving to accommodate our changing needs - but it can be difficult to keep up with all the innovations! This session will give you a tour of what's happening in open source databases, from someone who lives the adventures of open source data in her day job. You will travel from the well-trodden paths of relational databases, through the leafy glades of time series, to the landmarks of search and document databases. This session is recommended for people with an interest in software who want to learn about the overall trends, license changes, rising stars, and which database technologies are here to stay. about this event: https://c3voc.de

A demonstration and discussion around amateur paging. This year I will be providing a pager transmitter at EMF that primarily will announce the talk/event schedule (amongst other things yet to be dreamt up over a pint). This talk will give an overview of the specific flavour of pagers used for this system, the hardware used to build the transmitter, the amateur paging network trying to keep this relic of communication alive and some of the more interesting ways of receiving pages (e.g. turning a badge into a pager). Of course this assume everything goes to plan and works as expected, there is a non-zero probability some parts of talk will change from "this is how this works" to "this is how this should work, but this is why it does not". about this event: https://c3voc.de

A talk about how I set up a local CoderDojo club in my small market town; how I gathered together a group of like-minded people to become mentors; how I persuaded the 7-16 year olds of the town to give coding a whirl; how we won over the pensioners' gardening club, who thought children should be seen and not heard; and how over 5 years the kids became mentors and the mentors became lasting friends. about this event: https://c3voc.de

An audience interactive event; where willing volunteers collide with GPT-3 AI to present an informative, intellectual and light-hearted presentation to a receptive crowd. Unfortunately, they don't get to see the presentation before they talk about it! Powerpoint Karaoke will feature a selection of AI titled packs for attendees to present with only a moment to see what they’re about to talk about. The presentations will be interesting but we can't promise they'll be informative! With the rise of crypto-nonsense, washing machines bricked by ransomware and whatever the metaverse is never has there been a better time for people to take the stage and attempt to convince everyone that they know better than the AI overlord telling them what to talk about. Winners will be rewarded with a suitably terrible trophy for display in their office cubicle of choice, praised highly for their public speaking skills, and maybe get promotions by listing ‘Ideation and Blue Sky Thinktalking’ on LinkedIn. about this event: https://c3voc.de

The most profound change in radio technology in 100 years is happening now. Radios are transforming from the spaghetti of mind-bogglingly complex electronics into simple (but very fast) digitisers, and all the hard work is being done in software. Hence the name Software Defined Radio (SDR). Gnu Radio is a simple entry point to the world of SDR, and allows you to quickly prototype different kinds of radios by dragging, dropping, and connecting functional blocks. I'll demonstrate, and show that it's surprising what you can do with a radio receiver. about this event: https://c3voc.de

In 2009 a TED Talk by David Merrill showed small interactive tiles that talked to each other; an MIT “what if” project from their media lab. Little IoT devices that brought computers, toys and board game pieces together. In 2011(version one) and 2012 (version 2) a commercial version, Sifteo Cubes, was released, but I was unaware, thinking the dream prototype was just that, a dream not a reality. They passed me by… In 2014, the v2 software was open sourced - the inevitable precursor to failure - and the company bought by Drone/Robotics developer for the obvious design skills of the Sifteo team; they had, after all, reverse engineered and reapplied wireless keyboard controllers into one of the coolest toys ever! So, I came to them late. Too late. By 2015, the server the control software required, along with the online marketplace for the dozen or so games that were made, were long gone. The Sifteo cubes I’d just (re)discovered from a desperate eBay sale were now just useless, battery powered bricks. And they didn’t even click together! But I was stubborn. I wanted them to work. These little marvels of engineering and educational design. I had some of the software, a couple of the games, and none of the knowledge. Here’s how I managed to resurrect a legend, who I met, what some of them stole from me, and what I learned on the way about this event: https://c3voc.de

When I first watched Hackers in 1998, the idea of being able to remotely control ships seemed rather fanciful. After working on container ships as an engineer in the mid-2000s, it seemed every more unlikely. We didn't have a full-time Internet connection and all the vital systems were truly air-gapped. But things have changed - ships are becoming more and more connected and complex. As a result, 15 years later, I found myself sat in my pants on the sofa with the ability to control the steering on one of the world's largest cruise ships. We've been able to brick every PLC across tens of oil rigs, pay for food as the captain, and write rude words on the side of the ship. To get to this point, we had to go on a learning voyage across tens of different vessels, including offshore support tugs, super yachts, oil rigs and container ships. Join me on a whistle stop tour of what's on a ship, how it's all connected together, what threats there are and how we find the vulnerabilities. Lots of little tips and tricks that can help anyone examine industrial control systems, understand how they work, and then have a lot of fun with them!

Join the conversation with Professors Rachel Armstrong and Ioannis Ieropoulos, and artist Julie Freeman, to hear about how the ALICE artwork is a springboard for thinking about a new infrastructure that encompasses nomadic lifestyles, smart plumbing, resource autonomy - moving beyond fossil fuels and working with natural energy flows. This technology has global potential to disrupt energy and wastewater systems. Active Living Infrastructure: Controlled Environment (ALICE) is a "living" installation that communicates with microbes in real time by monitoring their electricity production so we can "respond" to them by feeding them with our liquid waste. Drawing together microbial metabolism, data, bioprocessor systems, artificial intelligence, low power electronics and digital displays, ALICE reveals the inner "life" and naturally-organised, imperceptible realm of microbes around us. To hold these digital "conversations" with microbes, ALICE uses the Microbial Fuel Cell (MFC) as a communications platform. MFCs are an organic energy source powered by microbes which facilitate contact between humans and microbes through electrical exchanges. The collected and analysed data can tell us about household resources, as microbes can give us information about our consumption, and reveal what we discard in our waste streams—while also powering our homes and, ultimately, cities. https://alice-interface.eu Come and see us in Null Sector! about this event: https://c3voc.de

Over my time in academia, I've endured a number of existential crises whilst learning about the concepts within philosophy that are required in order to undertake academic research. I figured that, if I'm going to spend the rest of my life constantly questioning my existence and reality itself, why not share this experience with others, too? A problem shared is still a problem that keeps you awake at night staring into the abyss unable to function. But hey, at least now I'm not alone. In order to explain these theories and share my recurrent episodes of screaming WHYYYYYYYY at the universe, I've collected a number of memes and references over the years to convey concepts such as what is it to 'exist', why the scientific method is just as 'made up' as anything else, how we define 'truth' and lots of other tasty things to create a pervasive, disjointed feeling that you just can't seem to shake. Join me in this journey and then we can all go and sit by the lake and have a good cry / scream / rock back and forth because what does it all mean and what even is real anyway and I'm off to go eat a cake because while I can't actually prove if the cake is a lie or not I'm convinced it is damn tasty and I NEED TO FEEL SOMETHING OTHER THAN THIS EXISTENTIAL UNCERTAINTY FOREVER OKAY? about this event: https://c3voc.de

In recent years automatic machine translation has dramatically improved in performance, with the availability of neural networks and huge amounts of data. Why does it work, and more importantly, when does it break? What kinds of language are machines terrible at translating, and is there anything we can do about it? What might change in the future? Come along to learn which aspects of a Universal Translator seem relatively plausible, which seem next to impossible at the moment, and some machine learning explanations for why the Enterprise's computer might not convey the gory details when a Klingon is insulting you. about this event: https://c3voc.de

As cringe as I often find it talking about myself, this seems to be the thing about my background that amazes people I mention it to. I spent 6 years failing to do a CS PhD, co-founded a (failed) fin-tech startup and watched the 2008 credit crunch from the inside of a multi-billion dollar hedge fund. Thanks to a chance meeting with an artist (who was hanging a door at the time), I rediscovered both my childhood love of drawing and a joy in the tech that I had started to hate. I'll talk about failing and reinvention; imposter syndrome; being neurodivergent; my experiences of the commercial world and the art world; finding a space in which you feel comfortable – but not *too* comfortable; and the power of collaborating. about this event: https://c3voc.de

The hurdy-gurdy is an ancient musical instrument (10th century) with drones and melody strings bowed by a rotating wheel, played by pressing keys which contact them at different points. It featured in TV series such as “Black Sails” and “Walking Dead” as well computer games. A major barrier is that they are very expensive at thousands of pounds each and built to order with lead times of over a year. Rather like bagpipes, they are loud. For pipers, practice e-chanters are available while nothing similar exists for the hurdy-gurdy. The Digi-Gurdy project started as a 3D printed version of the keyboard part of the instrument in isolation, with some internal electronics, for my own personal use to learn a few tunes on. After posting on Thingiverse, a website for sharing 3D printed ideas, I had many requests from people asking me to build them one. This open-source project has developed through many variations which I would bring to the talk, resulting in an all laser-cut wooden full-size hurdy gurdy design with a realistic crank handle system and a detachable playable keybox for travelling. It is an electronic device, with correctly placed keys, that outputs data via the industry standard MIDI communications system for electronic musical instruments, via a USB cable to an attached or wirelessly paired phone or iPad running suitable MIDI player software. It is a low-cost way to enter the Hurdy Gurdy world and allows practice anywhere using headphones, thus preventing eviction or divorce! about this event: https://c3voc.de

The Mayflower Autonomous Ship is a fully autonomous, AI powered research vessel, that will at the time of this talk will hopefully have completed its primary mission to cross the Atlantic from Plymouth UK, to Plymouth Massachusetts without any human intervention or control. The AI captain installed will guide the ship across the Atlantic, avoiding obstacles, plotting courses around the weather and balancing the many variables needed to safely cross one of the most dangerous oceans. As well as it's main goal to cross the Atlantic, it will also be operating a number of data collection and ocean science experiments to help researchers better understand our oceans, as well as developing new technologies to help automate science at the edge. This talk, will give a history of the Mayflower Autonomous Ship, a look into the exciting science conducted aboard including our Whale Song detector and Electronic Tongue, and how everything is brought together using open source and a great team. about this event: https://c3voc.de

Travelling by rail in most of the world is one of the safest forms of transport you can take, and in the UK even minor collisions make the news. But it wasn't always quite that way... This talk will be a potted history of the safety of the railways in the UK and Ireland, starting from the early days when signalling was thought of as an inconvenience, and anything with wheels on it which sort-of went round went on the track. Eventually, the railway companies learned the benefits of adopting safer methods of working (sometimes requiring some encouragement from the law), leading to the introduction of some Victorian methods we still use today. Finally, we look at the more modern era with the railway losing its way with privatisation, and onto the current time, where computers and paperwork solve everything. Perhaps. Featuring: Swiss Cheese, Charles Babbage vs. Brunel, working too hard, forgetting where you put your trains, losing your religion, a dark and stormy night, drunken driving, a loose screw, shifting foundations, and more. No previous knowledge of the rail industry is required. The talk will cover some recent fatal accidents at a high level. about this event: https://c3voc.de

A traditional Linux file system tree in the root file system has quite a number of directories with special purpose, documented in the Filesystem Hierarchy Standard (FHS). An operating system installation by default populates most of those directories with different kinds of files, e.g. by means of a package manager. When looking closer this theoretical order is quite a mess in practice. Alternative approaches to manage and update software components of the operating system such as MicroOS reveal the inconsistencies and require stricter separation of different types of files.

The Apollo Guidance Computer (AGC) was a critical element in the success of the Apollo Moon landing programme, and was one of the first digital computers to use the then new technology of integrated circuits. By modern standards, its design has many unusual aspects, such as: - The logic circuits were made entirely from 3 input NOR gates. - Design was split into 24 logic modules, but due to limits on gate/chip count per module, individual gates were sometimes 'borrowed' from unrelated modules. - Shift and rotate operations existed, but were not available during interrupts. - Numerical overflows disabled interrupts. - There was no stack. - Limited memory addressing range, combined with a need for ever more memory lead to a complex memory banking system. - Word length was 15 bits, ones-complement (mostly). - No floating point - everything done in integer - programmer responsible for avoiding overflows. - Single bit 'Up/Down' Analog to Digital conversion (kind of) throughout, with the curious side-effect that the faster the spacecraft was rotating, the slower the computer would run... On top of the limited hardware was built an impressive realtime system supporting cooperative multitasking, a virtual machine running interpreted commands, a powerful fault detection and restart system, and an innovative VERB NOUN user interface. This talk aims to describe the architecture, with particular focus on aspects which are unusual by modern standards. about this event: https://c3voc.de

simpledrm is a fbdev replacement implemented in the DRM kernel subsystem. It allows for smoother handover from the early boot phase to when a "real" DRM driver is loaded. In addition it allows for Wayland support on simple display adapters that do not have their own DRM driver.

Trains are one of the safest ways to travel, but it hasn't always been like that. In this talk I will introduce the basics of railway signalling, and look at how it has evolved over time - often in response to accidents and near-misses. You will find out how a single stray wire caused an accident that killed 35 people, why leaves on the line cause such a problem for the railways, and how signalling systems are designed to deal with the inevitable human error. Working from the early days of the railway to the present (and future), the talk will take you through a number of accidents, their causes and the improvements that were made after the accidents. This talk is suitable for any level of knowledge about railways - it aims to be understandable for complete beginners, and still have some interesting parts even for railway geeks. about this event: https://c3voc.de

Business processes evolve continuously, customer expectations and requirements change even faster. Process management and workflow support systems have a tendency to grow organically into fearsomely complex monolithic beasts while piling up technical debt in the process. Data migrations come at high cost, changing systems almost always require data to be converted into the new systems particular data model, which makes doing data migration verification both complex as well as costly. Using the open source/free software SQL database engine PostgreSQL, one of the leading Relational Database Management Systems, and in recent years the most popular database engine used in startups and scaleups, takes away the concern of future accessibility and integrity of the data itself. A middleware layer/REST API built with Symfony framework and a ReactJS based frontend ensure a fully responsive modern UX. Furthermore we use GitLab and Ansible for project management and automating our CI/CD environment. At OpenNovations we’ve created a solution called Aranei built with standard open source tools which generates a state of the art, open web standards based, user interface on top of any existing SQL data structure. Keep the same schema/structure between source system and archiving solution, or to use the notion of a controlled copy, is a much less cumbersome approach, as a one on one data verification can be performed. Not just the UI components themselves are generated by the metadata app modeling engine, also automated test scripts and a data dictionary are generated as part of the data verification process.

Keep the same schema/structure between source system and archiving solution, or to use the notion of a controlled copy, is a much less cumbersome approach, as a one on one data verification can be performed. Not just the UI components themselves are generated by the metadata app modeling engine, also automated test scripts and a data dictionary are generated as part of the data verification process. about this event: https://c3voc.de

Exploring data ethics through creative immersive tools with brainwave, and motion capture data. Is there a difference in sense of self (identity) between the human and the virtual? How does sharing your personal biometric data make you feel? How can biometric and immersive development tools be used in the computing classroom and dance studios to raise awareness of data ethics and immersive performance tools? We created 3D motion capture data from 2D RGB video sources using AI software. We recorded and visualised EEG using cheaply available equipment. We are currently producing a performance in Augmented Reality, using game development tools for animation data visualisation, particle systems, fragment shaders, etc. And data sonification with Python and Sonic PI. We will give a video demonstration of work in progress augmented reality ballet using the concepts we have developed. It is cool and awesome. about this event: https://c3voc.de

The SEGA Dreamcast was released nearly 25 years ago, but was discontinued after only 18 months on sale in the west, and was such a commercial failure that SEGA never made another console. Despite this short lifetime, a homebrew community formed, has not gone away, and has only become more passionate since. The most tangible demonstrations of this passion are the extensive hardware modifications that have been developed by hobbyists to drag the Dreamcast kicking and screaming in to the 21st century. Users can restore internet connectivity, replace the PSU or the commonly-failing disk drive (originally based on bespoke optical media), and even enable true digital video output. I will talk about the origins of the Dreamcast homebrew scene, and the development and implementation of the most popular of these mods that ensure the Dreamcast will live on for many years to come. about this event: https://c3voc.de

We have several ways to install and update openSUSE distributions, standard with zypper, atomic with transactional-update or using disk images created with kiwi or similar tools. But this are all RPM based. In some scenarios, it would be good to have an image based installation and update mechanism (image means /usr, not a full disk image). A PoC is MicroOS TIU (https://github.com/thkukuk/tiu), which allows to use either btrfs snapshots or several partitions (usrAB) for installation and update. This talk will give some insight into it. The current status, the problems, what it means for packaging, etc. We have several ways to install and update openSUSE distributions, standard with zypper, atomic with transactional-update or using disk images created with kiwi or similar tools.

D-Installer is the code-name of a experimental project for creating a new YAST-based installer designed to offer reusability, better integration with third-party tools and the possibility of building rich user interfaces over it. In this talk, we will explain the motivation of the YaST Team for creating a new installer and what possibilities this new idea brings. There will be time for diving into some technical details about the project architecture and we will show a live demo! You will hear about D-Bus, web interfaces, YaST and Cockpit. If you are interested in how all those pieces play together, do not hesitate to join us.

Default community distributions are running in the same issues for special architectures. Every Linux distribution has got mostly separate maintainers and hardware distributors are handling these communities really often disconnected. That has been identified also for the architecture s390x. Therefore, openSUSE, Fedora, Debian, SUSE, Canonical (Ubuntu) and Red Hat have established together with IBM a Linux Distributions Working Group for a better collaboration together and with the goal to achieve better support. In this presentation, you should receive an overview of a good collaboration between Linux distributions and what you can achieve together with such a Working Group.

Fire has been a ubiquitous technology for countless millennia, finding applications across many problem domains. This talk describes the development of a new product that brings fire into the wearable technology arena. Wearable technology is often limited to daily practicalities like reading emails on your wrist or tracking your fitness goals. In this talk you will witness large plumes of burning gas that can be a thoroughly impractical, but hilarious, addition to your wardrobe. about this event: https://c3voc.de

Margate, Kent is a phoenix rising from the ashes of Britain's great seaside institutions. This one-time jewel had been abandoned to decay and deprivation. The last 6 or 7 years have seen green shoots of regeneration begun by Turner Contemporary Gallery and is now rich in galleries, media consultants, music and film producers. Its High Street is an exemplar for retail re-purposing. Unfortunately, there remains a lot of deprivation and a widening digital divide. This talk is an engineer’s tale of moving to Margate from London. The opportunities, experiences and challenges had so far, and an ambition to bring more joy of tech to the area. I will talk about Margate's Maker community as context, and tell tales of working with artists and involvement with several community activities. I even mange to squeeze in a bit of IDEF0 modelling! about this event: https://c3voc.de

Unfortunately, you cannot pop magic Limitless style pills to improve your memory. But with a bit of understanding about how our memory works, we can introduce techniques that will help us remember important and even unimportant information. In this talk, I will talk a bit about the structure of memory and then discuss some techniques that anyone can use to improve their memory (when you want to). about this event: https://c3voc.de

**transactional-update** is the openSUSE way of a **Transactional Operating System update** and a core component of _openSUSE MicroOS_ / _Kubic_ and _SLE Micro_, making sure updates can be applied safely without affecting the currently running system. It's also supposed to play an important component in the future ALP. At lot of things have changed internally since the last talk at oSC19: The core functionality has been **rewritten in C++** (formerly Bash), including a **C++ and C API** and a **D-Bus interface**. From a user's perspective the transactional-update command line interface still looks the same, but we now have **Cockpit** and **dnf integration**. This talk will - give a **short overview of transactional-update** for those new to the concept. - introduce `tukit`, the command line interface for the API functionality. - present the new **Cockpit** interface for transactional-update. - present the **dnf** integration. - give an overview over other changes (SELinux support, Kernel Live Patching). - and we should also have some minutes left for questions and discussions. **transactional-update** is the openSUSE way of a **Transactional Operating System update** and a core component of _openSUSE MicroOS_ / _Kubic_ and _SLE Micro_, making sure updates can be applied safely without affecting the currently running system.

Sourcery is a program that builds root file systems consisting mostly of Go source code: of the 90,000 files in a typical sourcery root, there are only 12 or so programs. Other programs are compiled on demand to a ramfs-backed file system. Compilation takes a fraction of a second for most programs, and never more than 2 seconds. Once the program is compiled to a statically-linked, tmpfs-based binary, invocation is instantaneous. Because these images are mostly source, they can also be multi-architecture. Binaries present on boot have a path formed from the target os and architecture, e.g. /$OS_$ARCH/bin/init for init. Dynamically compiled binaries are placed in the tmpfs-backed /bin, since these binaries vanish on boot, the path can be simpler. The file system includes the full Go toolchain as well as all source code. Constructing the root file system, including the git clone steps and Go toolchain build, takes under 4 minutes; each additional architecture takes another 90 seconds (to ensure reproducible builds, the Go toolchain builds itself 3 times). Sourcery root file systems are designed for VFAT, a standard for firmware for x86, ARM, and RISC-V. A typical USB stick for sourcery would include a syslinux bootstrap for x86, required for those platforms; a kernel Image file for ARM; and a kernel file for RISC-V: the firmware for ARM and RISC-V is able to find boot kernels without using an on-stick bootstrap. Sourcery may be found at github.com:u-root/sourcery.

Advances in NLP and machine learning are allowing automatic processing of knowledge. An untapped potential of this revolution is the ability to change how people come up with ideas and solve problems. People tend to solve problems in linear ways. If my horse is too slow, I want a way to make it faster. It wasn't clear to many people of the 1800s that changes in industrialisation would lead to an entirely new way of going fast! So what happens when you do have all of the information, and when you can find subtle patterns occurring in vast swathes of data? What happens when an engineer's Alexa can tell you not just the answer to your question, but the answer to the question that you didn’t know you were asking? I would like to explore how AI may fundamentally change the human’s ability to think and invent, and the changes that this may lead to in society, drawing on my experience as the head of the world’s first AI augmented invention team with example patents and progress that has been made so far. about this event: https://c3voc.de
