How to survive a shit storm

"Ich möchte von meiner Erfahrung mit so genannten shitstorms berichten, mit den seismischen Empörungswellen, die durch das Internet rollen. Wie reagiert man? Wie fühlt sich ein shitstorm von innen an? Gibt es Nachwirkungen? Welche Kritik nimmt man sich zu Herzen und welche ignoriert man noch nicht einmal? Wie erhöht man seine Shitstormability? Ein Vortrag für die ganze Familie."

Solid scenario’s for sustainable software

Software is the interface between man and the digital machine. Although software is as essential as data, there is much more attention for data management than for sustainable software. In the public policy domain the importance of keeping software alive is largely underestimated. This should change at our earliest possible convenience. The jump forward should be: a systematic approach to software sustainability combined with an international knowledge exchange infrastructure for software sustainability. Other actions regarding software sustainability involve the Software heritage Project and de Software Seal of Approval.

How music can predict the human/machine future

From HAL to Wiimotes and Kinect, musicians have predicted the future of machine/human interaction. Because music connects with time, body, and emotion in a unique way, they test the limits of technology. Now it's time to work out what comes next. What's going on here - how did musicians manage to invent major digital interaction tech before anyone else? Before the iPad, the first commercial multi-touch product was built for musicians and DJs. Before the Wii remote, musicians built gestural controllers, dating back to the early part of the 20th century. Before the moon landing, Max Mathews' team of researchers taught computers to make music and sing, inspired HAL in 2001: A Space Odyssey, and may have even built the precursor to object-oriented programming.Music's demands - to be expressive, real-time, and play with others - can test the limitations of technology in a way people feel deeply, and help us get beyond those limitations.

Becoming a Polyglot: Lessons from Natural Language Learning

As a trained linguist and former university language instructor, people often assume that my natural language* (spoken, signed, or written) learning analysis background made learning to code easier for me. They might say something like “That makes sense, they’re languages, right? They have syntax.” These casual comments seem true on the surface when talking about parts of speech and variable types. But once you dig deeper, it becomes clear that there are far more differences than similarities between these types of languages despite the shared name. However, many skills and methods I have utilized in learning languages and teaching languages as an adult to adults have served me well as a developer. This talk first addresses key points of divergence between learning a natural language and a programming language. Perhaps most importantly, natural languages are meant for communicating with people and programming languages are meant for giving a computer directions. However, many areas of overlap exist in learning and perfecting these skills; these shared aspects of learning are the primary focus of this talk. (* And, yes, that’s the same ‘natural language’ as in ‘natural language processing.’)

Finish Him!

For a decade from the early 90's to the early 2000's, Williams' Digital Compression System (DCS) audio hardware reigned supreme in arcades and casinos, providing amazing sounding music, voice-overs, and effects, blowing competing systems out of the water. This talk will reverse the DSP hardware, firmware, and algorithms powering the DCS audio compression system, used on Midway coin-ops and Williams/Bally pinballs, like Mortal Kombat II/3/4, Killer Instinct 1/2, Cruis'n USA, and Indiana Jones, among others. A tool called DeDCS will be presented, which can extract, decompress, and convert the proprietary compressed audio data from a DCS game's sound ROMs into regular WAV format, taking you back to '92, when you tossed that first quarter into MKII, and Shao Kahn laughed in your face...

Reversing the Nintendo 64 CIC

This presentation covers our successful efforts to reverse engineer and clone the Nintendo 64's copy protection chip: the N64 CIC. We describe the processes and techniques we used to finally conquer this chip, nearly 20 years after its introduction. Nintendo's NES, Super NES, and Nintendo 64 used a series of copy protection chips known as CICs. As the consoles grew more sophisticated, so did the chips. While the NES and Super NES CICs have been cracked and cloned, up until recently the Nintendo 64's has remained an elusive target. Our team approached this chip by exposing the die (decapping) and optically imaging it, including its mask ROM. Through visual inspection we determined the CPU core and instruction set, and we were able to extract the program code from the mask ROM. We wrote an emulator on PC and ultimately cloned the chip on a PIC microcontroller.

The New Folk Tradition: Aesthetic and Community Resonance between Open Source Graphics and Fiber Arts

I discuss revivalist trends in art with relationship to the hand-made and folk tradition, specifically in fiber arts. Innovative artists, having digital fluency, easily navigate networked communities and collaborate openly. By comparing pixels to patchwork, vectors to stitches, bitmaps to patterns, and layers to quilts, they investigate the overlap among a variety of disciplines.

Multi-table Full Text Search with Postgres

Searching content across multiple database tables and columns doesn't have to suck. Thanks to Postgres, rolling your own search isn't difficult. Following an actual feature evolution I worked on for a client, we will start with a search feature that queries a single column with LIKE and build up to a SQL-heavy solution for finding results across multiple columns and tables using database views. We will look at optimizing the query time and why this could be a better solution over introducing extra dependencies which clutter your code and need to be stubbed in tests.

Don't Copy Data! Instead, Share it at Web-Scale

Since its start in 2006, Amazon Web Services has grown to over 40 different services. Amazon Simple Storage Service (S3), our object store, and one of our first services, is now home to trillions of objects and core to many enterprise applications. S3 is used to store many kinds of data, including geo, genomic, and video data and facilitates parallel access to big data. Netflix considers S3 the source of truth for all its data warehousing.The goal of this presentation is to illustrate best practice for open or shared geo-data in the cloud. To do so, it showcases a simple map tiling architecture, running on top of data stored in S3 and uses CloudFront (CDN), Elastic Beanstalk (Application Management), and EC2 (Compute) in combination with FOSS4G tools. The demo uses the USDA��s NAIP dataset (48TB), plus other higher resolution city data, to show how you can build global mapping services without pre-rendering tiles. Because the GeoTIFFs are stored in a requester-pays S3 bucket, anyone with an AWS account has immediate access to the source GeoTIFFs at the infrastructure level, allowing for parallel access by other systems and if necessary, bulk export. However, I will show that the cloud, because it supports both highly available and flexible compute, makes it unnecessary to move data, pointing to a new paradigm, made possible by cloud computing, where one set of GeoTIFFs can act as an authoritative source for any number of users.

Ensuring Climate Data Remains Public

How do we keep important environmental and climate data accessible amidst political instability and risk? What even counts as an “accessible” dataset? Could we imagine better infrastructures for vital data? By describing the rapid data preservation efforts of U.S. environmental data that started in the wake of the recent election, I’ll address these questions and the new and existing issues that preservation surfaced about the vulnerability of data infrastructures. I'll focusing on specific projects, including the work of EDGI, that is trying to address these challenges by creating alternate forms of access and infrastructure!

There's Nothing. New under the sun

Quick: say something about Ruby that hasn't already been said. Not easy, right? This community is prolific. In thousands of talks, Ruby's story has been told and retold. We heralded programmer happiness, path of least surprise, and confident code. We unleashed metaprogramming (until we tamed our DSLs). We built apps, tested them to death, and then legacy-rescued them. What's left to say? We could tell the same stories again, but that wouldn't be very DRY. What we need to hear was often said years ago, so this talk will help us rediscover timeless lessons from our community's greatest hits.

Robot Hacks: TASBot Exploits Consoles with Custom Controllers

TASBot is an augmented Nintendo R.O.B. robot that can play video games without any of the button mashing limitations us humans have. By pretending to be a controller connected to a game console, TASBot triggers glitches and exploits weaknesses to execute arbitrary opcodes and rewrite games. This talk will cover how these exploits were found and will explore the idea that breaking video games using Tool-Assisted emulators can be a fun way to learn the basics of discovering security vulnerabilities. After a brief overview of video game emulators and the tools they offer, I’ll show a live demo of how the high accuracy of these emulators makes it possible to create a frame-by-frame sequence of button presses accurate enough to produce the same results even on real hardware. After demonstrating beating a game quickly I’ll show how the same tools can be used to find exploitable weaknesses in a game’s code that can be used to trigger an Arbitrary Code Execution, ultimately treating the combination of buttons being pressed as opcodes. Using this ability, I’ll execute a payload that will connect a console directly to the internet and will allow the audience to interact with it. An overview of some of the details that will be described in the talk can be found in an article I coauthored for the PoC||GTFO journal (Pokemon Plays Twitch, page 6 ). Bio: Allan Cecil (dwangoAC) is the President of theNorth Bay Linux User’s Group. He acts as an ambassador for Tasvideos.org, a website devoted to using emulators to complete video games as quickly as the hardware allows. He participates in Games Done Quick charity speed running marathons using TASBot to entertain viewers with never-before-seen glitches in games. By day, he is a senior engineer at Ciena Corporation working on OpenStack Network Functions Virtualization orchestration and Linux packet performance optimization testing.

Improving TruffleRuby’s Startup Time with the SubstrateVM

Ruby applications can be broadly split into two categories: those that run for a short period and those that stick around for a while. Optimizing performance for one often comes at the expense of the other. Over the years, alternative Ruby implementations have demonstrated remarkable performance gains for long-lived applications -- so-called peak performance -- but often lose out to MRI for short-lived applications. In this talk, I'll introduce the SubstrateVM and show how we use it to massively improve TruffleRuby's startup time with minimal impact on peak performance.

wallet.fail

In this presentation we will take a look at how to break the most popular cryptocurrency hardware wallets. We will uncover architectural, physical, hardware, software and firmware vulnerabilities we found including issues that could allow a malicious attacker to gain access to the funds of the wallet. The attacks that we perform against the hardware wallets range from breaking the proprietary bootloader protection, to breaking the web interfaces used to interact with wallets, up to physical attacks including glitching to bypass the security implemented in the IC of the wallet. Our broad look into several wallets demonstrates systemic and recurring issues. We provide some insight into what needs to change to build more resilient hardware wallets.

Jailbreaking the 3DS Through 7 Years of Hardening

The 3DS was one of Nintendo's first serious attempts at security, featuring a cool microkernel based OS and actual exploit mitigations. That didn't stop it from getting hacked pretty hard, making it possible for people to write their own homebrew software for the console. But Nintendo isn't one to back off from a fight and, as a result, has put significant effort into not only fixing vulnerabilities but also introducing new security features targeted specifically at killing exploit techniques used by hackers. This talk will describe hacking the console through all these defensive features by walking through a 0-day exploit chain that takes us all the way from zero access to a full system jailbreak.
