by Andrew Back 21 Dec '17

21 Dec '17

Hello, Details can be found below for the 63rdm, and first meeting of 2018, the theme for which is open source musical software and hardware. Regards, Andrew // Event #63 — Collaborative music making, ultra-low latency audio and sensor processing. On the 18 January 2018, 18:00 - 21:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. http://oshug.org/event/63 We start the new year with an event on the theme of open source musical software and hardware. — Bela, an embedded platform for ultra-low latency audio and sensor processing Bela started off as a research project at Centre For Digital Music (Queen Mary University of London) and is now a commercial product, mainly aimed at makers, programmers and researchers that work with audio. The platform is based on a BeagleBone Black with a custom expansion cape and a dedicated software environment. The board runs Debian Linux with Xenomai as a real-time co-kernel. The combined use of Xenomai and the BeagleBone Black's on-board PRU microcontroller allows to achieve sub-millisecond latency for audio and sensor processing, while node.js is used to provide a user-friendly web-based IDE. The project is entirely open source, hardware and software. * Giulio Moro is a PhD student in the Centre for Digital Music at Queen Mary University of London. A sound engineer by training, he is now researching in the field of performer-instrument interaction. He is one of the inventors and core developers of Bela. — Female Laptop Orchestra: exploring geographical, cultural, technical and artistic challenges of collaborative music making As a collective of female musicians, artists, engineers, computer scientists and researchers, Female Laptop Orchestra has been pushing the boundaries of technology and cross-cultural co-located and distributed collaborative music making since 2014. Besides musical instruments, we use a variety of open source and commercial tools to create music, stream music and connect with our audience during the performance. We often collaborate with classical composers and ensembles, filmmakers, visual designers, choreographers and dancers. Recently, we also collaborated with members of Women in Music Technology (a student organization whose goal is to encouraging more women to join the music tech field of study and highlight the often unsung role of women in music technology, based at Georgia Tech Centre for Music Technology in US) and Sonora (a collaborative network bringing together artists and researchers interested in feminist manifestations in the context of the arts, based in Brazil). * Nela Brown is a sound artist, technologist, researcher and educator. In the past decade, she composed music and designed sound for award-winning projects including theatre performances, dance, mobile, film, documentaries and interactive installations. She is the founder of the Female Laptop Orchestra (FLO), an eclectic group of female musicians and technologists exploring co-located and distributed collaborative music making within different contexts and across different geographical locations. As a creative director of FLO since 2014, Nela co-ordinated 7 national and international FLO performances involving 36 collaborators from 21 different countries. — Talk #3 TBA Note: Please aim to arrive by 18:15 as the event will start at 18:30 prompt.

OSHUG 62 — RISC-V, RISC-V, RISC-V, Thursday 23rd November.
by Andrew Back 08 Nov '17

08 Nov '17

Hello, Details can be found below for the 62nd meeting, the theme for which is the RISC-V open ISA. Regards, Andrew // Event #62 — RISC-V, RISC-V, RISC-V On the 23 November 2017, 18:00 - 21:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/62 The sixty-second meeting will be on the theme of RISC-V, an open ISA which started life at the University of California, Berkeley. A joint meeting with the BCS Open Source Specialist Group. — Bringing up cycle-accurate models of RISC-V cores The openness of the RISC-V ISA has enabled the development of many open-source RISC-V cores with varying capabilities. Choosing an implementation that meets given requirements can be done to some extent by comparing specifications and other attributes of the cores, but any decision must be based on actual testing. Using Verilator to generate cycle-accurate models enables rapid development of testing platforms. This talk provides a report of our experience bringing up cycle-accurate models of two cores in particular, RI5CY from the PuLP project, and Clifford Wolf's PicoRV32. For testing, a software ecosystem consisting of a compiler, binary utilities, debugger, and an interface between the model and debugger accompanies the Verilator model. To compare the cores, we used the GCC test suite and the RISC-V ISA test suite for measuring correctness, and the Bristol/Embecosm Embedded Benchmark Suite (BEEBS) to compare performance. All code and scripts used for the implementation are open-source, and can be re-used by others who wish to do similar exercises with other RISC-V cores. * Edward Jones has a background in parsing techniques and works at Embecosm on LLVM and GNU toolchains. He is also involved in research by Embecosm to investigate ways in which the software tool chain can reduce program energy consumption. Edward Jones is a Computer Science graduate of the University of Kent. — FreeBSD/RISC-V and Device Drivers The FreeBSD port to RISC-V 64-bit ISA was added in January 2016. FreeBSD is the first operating system that officially supported RISC-V in the main repository. Since its introduction, support has evolved, RISC-V privileged architecture has updated a few times. The platform is maturing making it suitable for general, commercial, research and educational use. The GCC v7.0 target for RISC-V was officialy upstreamed and NVIDIA is planning to ship all of their GPUs with RISC-V coprocessor enabled in the future. Several companies have announced the start of RISC-V chip development and many universities are taking RISC-V as a target architecture for doing research. The world first RISC-V microcontroller-class board HiFive1 was released and we are getting closer to the first general purpose board to become available! This talk will describe the current status of FreeBSD/RISC-V, toolchain and supported simulators. The porting process as well as describing the latest changes made to FreeBSD in order to support the latest RISC-V privilege specification (v1.10). This includes enabling by default FDT support and drivers attachment change, SBI interface, compiler flags/built-in definition changes, support for updated BBL boot loader, RISC-V privilege levels, initial page tables build, page table entry flags and other changes. An overview of FreeBSD device drivers subsystem will also be covered describing the device frameworks, buses and kernel-interfaces that exists in FreeBSD (e.g. Newbus, cdevsw, bus_dma, SYSINIT, vt, sound, ifnet, spibus, etc), how to use and configure them and how to debug a device driver. This should answer the question: How to write device driver for FreeBSD/RISC-V? * Ruslan Bukin is a Research Associate at University of Cambridge Computer Laboratory. He has been a FreeBSD user since 2002 and src committer since 2013. His main interests and contributions to FreeBSD are related to computer architectures support, performance monitoring technologies support, hardware tracing technologies (Intel PT), devicedrivers, DMA engines and DMA frameworks, hardware security (Intel SGX, CHERI), heterogeneous computing. Ruslan is the lead developer of the FreeBSD/RISC-V project. He obtained a Computer Science degree in 2008 from Peoples' Friendship University of Russia in Moscow — Talk #3 TBA Note: Please aim to arrive by 18:15 as the event will start at 18:30 prompt.

OSHUG 61 — Reimagining EDSAC, NetBSD Updates, Semantic & Change Coupling of Software Classes, Thurs 19th October.
by Andrew Back 10 Oct '17

10 Oct '17

Hello, Details can be found below for the 61st meeting, which is in just over a week, so please don't delay in registering if you plan to attend. Best, Andrew // Event #61 — OSSG AGM, Reimagining EDSAC, NetBSD Updates, Semantic and Change Coupling of Software Classes. On the 19 October 2017, 18:00 - 21:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/61 The meeting this month will start with the BCS OSSG AGM and this will be followed by a talk on recent and planned improvements to NetBSD, a report from Chip Hack EDSAC Challenge, and finally a talk on the interplay between semantic coupling and co-change of software. — BCS Open Source SG - AGM All members of OSHUG are welcome to attend and OSHUG members are encouraged to put themselves forward to join the committee. In particular we would welcome anyone to join the event organizers who arrange the speakers for each month and the occasional all-day workshops. Currently we have Sevan Janiyan, @ndy Bennett and Andrew Back as event organizers on the committee. — Updates to the NetBSD operating system since OSHUG #57 & #58 Since the workshops held earlier this year, numerous changes have been made to the NetBSD operating system to ensure future workshops are easier for users and work smoother from the outset. This talk will cover some of the improvements made so far and what's currently in the works. >From wrestling with the u-boot firmware to new tools included in the os and much more. * Sevan Janiyan is founder of Venture 37, which provides system administration & consultancy services. As a fan of operating systems and computers with different CPU architectures, in his spare time he maintains builds of open source software on a variety of systems featuring PowerPC, SPARC and armv7l CPUs. He hopes to own a NeXTcube & OMRON LUNA-88K2 one day. — Reimagining EDSAC: The ChipHack experience ChipHack is an occasional 2 day workshop introducing students and hobbyists to FPGA design. This year, ChipHack was sponsored by the BCS OSSG and Computer Conservation Society. To celebrate the 60th anniversary of the BCS, the workshop was extended by half a day and attempted to reimagine one of the earliest valve computers, EDSAC, designed by the BCS' founding president, Prof Sir Maurice Wilkes. * Mary Bennett led the team putting together the technical content of the workshop. She will report back on what was achieved, from the three implementations of the computer, to the diverse reimagining of the original peripherals. The result is a legacy of lectures and videos, to allow anyone to run their own ChipHack course. — The Interplay between Semantic Coupling and Co-Change of software classes During maintenance, developers must ensure that related entities are updated to be consistent with these changes. Studies in the static change impact analysis domain have identified that a combination of source code and lexical information outperforms using each one when adopted independently. The presentation has two aims: first, to compare the effectiveness of measuring semantic coupling of OO software classes using (i) simple identifier based techniques and (ii) the word corpora of the entire classes in a software system. Second, to empirically investigate the interplay between semantic and change coupling. * Dr Andrea Capiluppi joined the Department of Computer Science at Brunel University London (UK), as a Lecturer in Software Development in May2012. Between 2009 and 2012 he was at University of East London, working as a Senior Lecturer in Software Engineering. Before that, he worked as a Senior Lecturer and at University of Lincoln between 2006 and 2009. Andrea's research and teaching interests focus on Software Evolution and Maintenance, as well as the construction, evaluation and maintenance of Social Networks. Andrea is mostly interested in the use of open technologies and in understanding how they can improve learning and teaching as well as the production of software and other artefacts. Note: Please aim to arrive by 18:15 as the event will start at 18:30 prompt. // -- Andrew Back http://abopen.com

This will cover key concepts and LMS7002M FPRF IC architecture, and include simple digital radio examples along with a demonstrations of advanced systems, such as 4G femtocell. Details can be be found below. Regards, Andrew // OSHUG #56 — An introduction to software-defined radio with LimeSDR On the 24 March 2017, 09:00 - 17:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: https://events.bcs.org/book/2451/ A Software-Defined Radio (SDR) is a highly reconfigurable radio that can be used for many different radio applications through simply changing the software that links with it. An example of such a reconfigurable radio is the LimeSDR, which can both transmit and receive data and voice, using just about any wireless system. The LimeSDR was launched by Lime Microsystems in May 2016 via a crowdfunding campaign, and is now shipping to over 3,500 customers worldwide. It is based on the Lime Microsystems LMS7002M Field Programmable RF (FPRF) 2x2 MIMO transceiver, which continuously covers frequencies from 100kHz to 3.8GHz. The LMS7002M has been successfully used in a wide range of digital radio applications, including 2G/4G Femtocell base stations, GNSS, DAB, DVBT receivers and RF test and measurement equipment. The LimeSDR also includes an FPGA and USB 3.0 to provide host connectivity. — Workshop scope The heart of the day is to provide a practical ‘hands-on’ afternoon session using the LimeSDR with the Lime Suite GUI and FFT Viewer. Then to use GNU Octave and Pothos to make some very simple digital radio examples. To facilitate this, the morning will include introductory talks explaining the purpose of the various analogue and digital blocks included in the LMS7002M. It will also include tutorial material covering the key concepts required to understand modern digital radio transceivers, and how to use them, as well as practical issues associated with radio reception. In addition the day will feature some advanced demonstrations showing the full capabilities of the LimeSDR and its LMS7002M transceiver, including 4G Femtocell, as well as educational examples such as a simple OFDM transceiver data link. — Participant requirements ** Participants are required to bring a laptop computer with USB 3.0 ** Minimum computer hardware requirements are USB 3.0 capability and 2GB RAM. Although no prior knowledge of radio is required, an awareness of basic terminology will be very helpful. Basic computer programming and administration skills will also be helpful.

OSHUG 55 — FPGA projects past, planned and possible, Thursday 16th February.
by Andrew Back 07 Feb '17

07 Feb '17

Hello, Registration is now open for the February meeting, details of which can be found below. We also still have space for 1 or 2 more short talks of 10-15 minutes, so if you have an idea for a talk, get in touch! regards, Andrew // Event #55 — FPGA projects past, planned and possible On the 16 February 2017, 18:00 - 20:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/55 The fifty-fifth meeting will feature a series of shorter talks that explore past, planned and possible projects which use FPGAs. — FPGA Projects - What would I build and why would I want to PLAs have been interesting ever since the 70s when digital logic often became complex, consuming unnecessary space and power. Back then the cost of PLA deployment was high and it has continued to be high until recently. Now that we have powerful, low cost development platforms and relatively cheap FPGAs the cost equation has shifted radically. * Paul Tanner is a consultant, developer and maker in wood, metal, plastic, electronics and software. His day job is IT-based business improvement for SMEs. By night he turns energy nut, creating tools to optimise energy use. Paul graduated in electronics and was responsible for hardware and software product development and customer services in several product and service start-ups, switching to consulting in 2000. — Using FPGAs to solve realtime problems Microcontrollers a great platform to solve basic control problems in electronics, with simple motor drivers and sensors readily avaiable and easy to integrate. However, when the motor control becomes more complex with BLDC and FOC things get much more tricky. When you have to use multiple BLDC motors and more complex sensors with image processing the poor microcontroller quickly becomes to swamped to provide control in realtime. This is where adding FPGA technology makes a great deal of sense particularly in mutli-discipline projects like robotics where many sensors, motors and image processing will need to be managed and controlled concurrently. A robotics platform must therefore contain both concurrent hardware resources, algorithmic control through soft or hard cores along with communication protocols. * Alan Wood has been working with parallel distributed programming for several decades. His recent work includes smart grids, 3D printers, robotics, automation and biotec diagnostics. His current research is focused on machine learning, inference and image processing for embedded applications using FPGA and multi-cores. He is a long term advocate and moderator (aka Folknology) for xCORE and other opensource communities, as well as a founder of Surrey and Hampshire Makerspace and myStorm FPGA development boards. — FPGAs in the Cloud? It is no secret that FPGA based computing machines are great at dealing with certain types of workloads that conventional CPU based machines can not efficiently handle. These machines, alongside their GPU and even custom ASIC based brethren, have been filling up racks in large data centres all over the globe helping speed up systems that have components of machine learning, complex analytics and even video processing. This short talk will have a look at the state of FPGAs in the datacenter and discuss the recent developments around the availability of FPGA equipped computing nodes in commodity cloud providers. * Omer Kilic is an Embedded Systems Engineer who enjoys working with small connected computers of all shapes and sizes. He works at the various intersections of hardware and software engineering practices, product development and manufacturing. — Chip Hack 2017 & EDSAC Challenge This talk will introduce and issue a call for participation for two events that are being hosted as part of the Wuthering Bytes technology festival, that will take place in Hebden Bridge in September, in the week following Open Source Hardware Camp 2017. Chip Hack is a two day hands-on workshop that provides a gentle introduction to programming FPGAs and is aimed at novices with no prior experience of Hardware Description Languages (HDLs) or FPGAs. This will be followed immediately by a challenge event, during which a small team of experts will work to extend a basic functional FPGA model of EDSAC — the pioneering computer designed and constructed at Cambridge University, and which was operational by 1949. * Dr Jeremy Bennett is founder and Chief Executive of Embecosm, a consultancy implementing open source compilers and chip simulators for major corporations around the world. He is a author of the standard textbook "Introduction to Compiling Techniques" (McGraw-Hill 1990, 1995, 2003). Contact him at: jeremy.bennett(a)embecosm.com.

Hello, There are no hardware talks this month, but there will be an excellent series of 3 talks hosted by the BCS OSSG next Thursday, on theme of personal privacy online. Details below. Regards, Andrew // Personal Privacy Online (The Dark Web, Investigatory Powers Act) On the 19 January 2017, 18:00 - 20:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: https://events.bcs.org/book/2408/ We explore the theme of personal rights and privacy on the modern Internet, with a talk on The Dark Web, covering insights on one of the larger anonymous marketplaces online and another on the new Investigatory Powers Act. — The Investigatory Powers Act: What is it? The Investigatory Powers Act also known as the Snoopers Charter is now law, find out what that means for you and your company. The Snoopers Charter would require metadata on every email, website visit and social media log to be recorded. It covers hacking and mass hacking performed by Government agencies. Its powers can be enforced across the world. It contains over 270 clauses and dwarfs the computer misuse act in terms of size, so this is going to be a speed run covering some of the high points. * Glyn Wintle is a security evangelist and software engineer. He has given evidence in Parliament, frequently gives technical talks about security and is well know for his work with the Open Rights Group. — The Dark Web Within the last years, governmental bodies have been futilely trying to fight against dark web hosted marketplaces. Shortly after the closing of “The Silk Road” by the FBI and Europol in 2013, new successors have been established. Through the combination of cryptocurrencies and nonstandard communication protocols and tools, agents can anonymously trade in a marketplace for illegal items without leaving any record. This talk will presents a research carried out to gain insights on the products and services sold within one of the larger marketplaces for drugs, fake ids and weapons on the Internet, Agora, and on new developments after the demise of Agora. The team behind the research included Andres Baravalle, Sin Wee Lee, Germans Zaharovs (research intern) and Mauro Lopez Sanchez (final year project). The work has been featured on the front page on The Times and on the Guardian, amongst other media. * Andres Baravalle works in the in the University of East London as Senior Lecturer in Computing. He has been working in academia since 2004 (University of Turin, University of Sheffield, Open University, University of East London), while also working as a contractor in industry. Andres has been developing in LAMP environments since 1999 and managing development teams since shortly after. In the past years he has been combining his expertise in web technologies with an interest on security and data science. “ He once made a student cry - by praising his work.
