Portugal provider NOS and 4G box
by LDV 19 Feb '21

19 Feb '21

Hi everyone, NOS is a provider here in portugal. They own the boxes you get when you have a 4G access with them. My contract is over. But I still have the hardware for the moment. I just got a concurrent prepaid 4G SIM. I tried to access the web interface on the LAN and it asked to insert a SIM. The box is Huawei hardware. (locked with NOS settings) When I tried the new SIM, I almost bricked/locked it but didn't. I could use that box a moment and give it back to them after their shop re-opens (locked-down !) Can I safelly install openWRT on it without damaging the hardware ? is it safe legally ? So if yes : could anyone give me directions to start. I have 5€ on my bank account (don't worry it's just to say : I must manage to do it) (nice exercise no ?) ;D Thanks in advance. -- /*____________________________________________________________________________*/ /* Louis-David VENANCIO aka Meta-4 /// +351.968.247.846 */ /* https://www.3DLibre.com owner. /* Rua das Romeirinhas, lote n°21 - 7540-187 Santiago-do-Cacèm - PORTUGAL */ /*____________________________________________________________________________*/

JTAG options
by Sevan Janiyan 18 Feb '21

18 Feb '21

Hello, I have some Meraki access points which I'd like to re-flash with OpenWRT as the devices with the stock firmware are useless without a contract to tie it into the hosted management platform and Cisco removed the command used to reflash the device from the firmware environment before they were EoLed, hence leaving the JTAG route as the only option. I was wondering, what is the cheapest device I can get away with for use with OpenOCD? Could I get away with using an SBC without investing in new hardware? Regards, Sevan

WB 2020 and OSHCamp cancelled.
by Andrew Back 16 Jul '20

16 Jul '20

It may come as little surprise to learn that the Wuthering Bytes festival is cancelled this year and so is Open Source Hardware Camp. That is, unless someone would like to take the lead on organising a mini online event around the same time, end August / early September. There were a few replies to the call and just prior to lockdown I pretty much stopped planning both events, so haven't approached any potential additional speakers. If there is interest in hosting something online just drop me a line off-list. Cheers, Andrew -- Andrew Back http://abopen.com

BCS OSSG / OSHUG July meeting: An Evening on the theme of FPGAs
by Sevan Janiyan 02 Jul '20

02 Jul '20

Hello, July's OSSG/OSHUG (online) meeting is happening on the 16th. We have three speakers giving talks on the theme of FPGAs. Details of talks as follows (registration link at the end) 1) Why the J-core open processor is cool The patents on the bestselling processor of the 1990’s finally expired, and it’s been cloned as open hardware. J-core scales from running SMP Linux down to fitting in a tiny 5000 cell ICE-40 FPGA, and we just uploaded a new open source GPS receiver built around it to github. Rob Landley maintains the J-core Board Support Package, used to maintain busybox, maintains toybox (the command line utilities used by Android), and used to be the linux kernel documentation maintainer. 2) Yosys and nextpnr – open source FPGA update Find out about the newest developments in Yosys and nextpnr, including experimental Xilinx support, synthesis improvements and new place and route algorithms! This talk will also discuss some of the future work that is planned, with an ambitious target to support 1-million-LUT scale designs on UltraScale+ devices by the end of the year. David Shah is a self-employed developer working on nextpnr, the open source FPGA place-and-route tool. His previous work also includes Project Trellis, open source bitstream documentation for the Lattice ECP5 FPGAs. 3) Repurposing Obsolete FPGA-based Products as Development Kits Commercial FPGA development boards can be relatively cheap or they can have a lot of logic resources and features, but never at the same time. When commercial products with large FPGAs become obsolete, they can often be found dirt cheap on eBay. With a little bit of effort, some of these products can be reverse engineered and repurposed as generic FPGA development kits. This talk will show some examples, and discuss techniques that can be used to reverse engineer these kind of products. Tom Verbeure is a hardware engineer at Nvidia where he works on monitor technology. Before Nvidia, he worked on communication ASICs at Barco, Alcatel and Conexant. When he’s not mountain biking in one of the many parks around the SF Bay Area, you can probably find him in his garage, looking through a microscope trying to trace tiny wires on an old PCB, or burning up an LED panel in a misguided attempt to control LED cube with a Cisco WAN modem.

OSHUG #78: LoRaWAN: Long Range Wireless for the Internet Of Things
by Andy Bennett 15 Apr '20

15 Apr '20

Hi All, Registration is now open for the 78th meeting, held in partnership with the BCS OSSG. Details below. This will be a remote meeting so you can enjoy the speakers and discussion with other attendees from the comfort of your own home. Cheers, Andy // 16th April 2020, 17:30 - 20:30 via BCS Webinar http://oshug.org/event/78 This month we’ll be hosting our evening of talks online. You can join remotely from the comfort of your own home to listen to the speakers and chat in realtime with the other attendees. LoRaWAN is a Long Range Wide Area Networking technology that has been quietly sitting in the background of many IoT systems for several years now. This month we’ll hear from speakers who were early adopters of the technology. We’ll find out what is it, how it works and, most importantly, what they have achieved with it. AGENDA 18:15 – Join online meeting to chat with other participants 18:30 – Presentations 20:30 – Close This is a joint meeting with the British Computer Society Open Source Specialist Group. We are currently finalising the details for registration and connection so please save this time in your diary and look out for more information on Tuesday 14th April. We shall be live streaming via GoToWebinar and recording the talks for later posting on YouTube. — LoRaWAN TBA. Andrew Tierney (@cybergibbons) — The Things Network 5 years on Amazing how time flies! Mike looks at how LPWAN has progressed since he first got involved with The Things Network in 2015. He will look at the technology (radio, devices and code) involved, how to build and deploy your project, and finish with a look to the future of TTN with 5G arriving. Mike Beardmore (@mikethebee) has surfed the wave of opportunities for a creator since the transistor replaced the ‘tube’. A life of learning about constant change has been a foundation for working with the recent LPWAN blooming. An active Maker using additive & subtractive tools, he is an advocate for Hackspaces, OpenSource and Creative Commons. — LoRa trials (and tribulations) A few years ago a group of us came together to see what we could do about measuring actual pollution levels “where you are”. We were disappointed that the only hyper-localised data available came from hard-to-trust models that used widely-spaced sensors. We won some funding to build and test a prototype based on good quality sensors that communicated via a connected smart phone to a cloud-based data store, the data being visualised on a web app. This allowed people to compare alternative routes and select the best ones. The main feedback from these trials was that we needed to make the device much easier to use, smaller and lighter so we looked at ways to make the sensor self-contained. Along came LoRaWAN as one way to achieve this. The prototype was completely redesigned and we have been testing and refining that since. Unhappily, trialling with schools is currently suspended for obvious reasons but we think we are getting there. The talk will be about our learnings and future options under consideration. Paul Tanner (@paul_tanner) is an experienced engineer and project manager. He has held management positions in several tech startups and developed numerous electronic and software products. He has worked on a diverse range of IT projects in the roles of CTO, project manager, developer and architect. Paul’s recent projects have been focused on practical implementation of the “Internet of Things”. These have included two consumer energy portals, an assisted living care-in-the-home system, an assistive street and an energy-optimised smart house and (currently) a portable pollution monitor. He has also been an advisor and beta tester for a smart heating product. Paul now focuses on “public good” projects, especially in renewable energy, assisted living and cleantech. He is open to whatever roles are appropriate either as an individual or by bringing in a small team. Paul is a graduate of MIT with a BS in Electrical Engineering. Whilst not busy with his family he is a “maker” and clean energy enthusiast. Note: Please aim to connect by 18:15 as the event will start at 18:30 prompt. -- Best wishes, @ndy -- andyjpb(a)ashurst.eu.org http://www.ashurst.eu.org/ 0x7EBA75FF

Open Source in Government (BCS OSSG)
by Andy Bennett 18 Feb '20

18 Feb '20

Hi OSHUG People, On the evening of Thursday, 20th February, the BCS Open Source Group are hosting an event on "Open Source in Government" in London. Registration is now open at https://ossg200220.eventbrite.co.uk/ We've got a good line-up of celebrity speakers: Open Source Excuses – busting the myths Terence Eden Why don’t government departments and NHS organisations want to adopt open source? This talk looks at common reasons given. It will give you real life examples of barriers to coding in the open, and practical tips for adopting open source. Terence Eden is the Head of Open Technology for NHSX. He is a technology & policy expert. He teaches government courses on AI and ethics. He was formerly the UK Government’s representative to the W3C. He speaks around the world on open standards, open source software, and open data. Current political challenges and opportunities for Open Source in Europe Astor Nummelin Carlberg The campaign to save Open Source development from the EU’s Copyright Directive was indicative of the current status of Open Source advocacy in the EU—while ultimately successful, it was more reactive than proactive. The most important lesson from this campaign was that Open Source was not targeted by policy makers, simply forgotten and misunderstood. This suggests that while Open Source has gone mainstream, Open Source advocacy has not kept up. As there are both more opportunities and regulatory risks for Open Source in the European Union, more, if not all, Open Source community stakeholders need to increase their capacity to deal with policy making. At the least, we need to make sure that Open Source never again becomes an unintended regulatory casualty. There are several very tangible steps that can be taken to do this. Since Open Source is becoming ubiquitous at the same time as there is an eagerness to regulate tech in the EU, the time is now to mature Open Source advocacy and increase its effectiveness. Astor Nummelin Carlberg is OpenForum Europe’s Policy Director, responsible for policy development and advocacy. Before joining the team he was an Accredited Parliamentary Assistant in the European Parliament, and has studied in the United States and Germany. He has extensive experience of European policy making processes, communications and catalysing networks and communities for advocacy impact. Making the case for open with Governments Irina Bolychevsky Irina Bolychevsky is the founder and director of Redecentralize.org. She’s a digital strategist and expert on data, open data, data platforms, standards, privacy and decentralised technology. She led the ckan open source data platform to international adoption, served on Open Knowledge Foundation’s senior management team and now as a board member and developed the personal data infrastructure programme within the UK’s Government Digital Service. She developed the Smart Dubai’s and UAE federal policy, regulatory, commercial and technical frameworks for data exchange and ran one of the first UK data trust pilots and researched digital identity for the Open Data Institute. The event page is here: https://ossg.bcs.org/blog/event/open-source-in-government/ ...and you can register for a (free) ticket here: https://ossg200220.eventbrite.co.uk/ Hopefully I'll see a few of you there! Whilst this is not an OSHUG event, it is organised by the BCS OSSG with whom we (OSHUG) often organise joint open source events. I thought it might be of interest to some of you.

BCS OSSG/OSHUG: An Evening on Modern Programming Languages
by Sevan Janiyan 29 Oct '19

29 Oct '19

Hello, During this evening, held jointly with OSHUG, we look at the latest in open source programming languages. Three talks from three highly respected speakers Note. We are in the new BCS London offices at 25 Copthall Ave EC2R 7BP. Register at https://ossg211119.eventbrite.co.uk/ Tea/coffee will be served from 6:00pm, with the talks from 6:30pm. Each talk will last around 30 to 45 minutes including any questions. We shall be livestreaming and recording the talks for later posting on YouTube via GoToWebinar. Please register at: https://attendee.gotowebinar.com/register/2652791007348976652 An introduction to Perl6 Simon Proctor An introduction to the newest version of Perl with an emphasis on some neat features. With 17 years as a professional web developer (in a range of languages) and over 30 years of doing it for fun Simon Proctor has just about started to understand what he’s doing. He’s on occasion been known to take things seriously. Julia – A fresh approach to numerical computing Avik Sengupta In this talk, Avik will demonstrate how Julia combines dynamic, high level source with a high performance runtime code. He will show what makes Julia unique among programming languages, and how it enables high quality numeric computing libraries. He will survey the machine learning / deep learning ecosystem in Julia, and talk about how that can be extended to new kinds of modelling using differentiable programming. The talk will begin as an introduction to the language, and finish by showing how it opens up new paradigms of computing. Julia is the fastest high performance open source computing language for data, analytics, algorithmic trading, machine learning, artificial intelligence, and many other fields. Julia solves the two language problem by combining the ease of use of Python and R with the speed of C++. Avik Sengupta is the head of product development and software engineering at Julia Computing, contributor to open source Julia and maintainer of several Julia packages. Avik is the author of Julia High Performance, co-founder of two artificial intelligence start-ups in the financial services sector and creator of large complex trading systems for the world’s leading investment banks. Prior to Julia Computing, Avik was co-founder and CTO at AlgoCircle and at Itellix, director at Lab49 and head of algorithmic solutions at Decimal Point Analytics. Avik earned his MS in Computational Finance at Carnegie Mellon and MBA Finance at the Indian Institute of Management in Bangalore. Evolving Languages: 5 Steps to Go Charles Forsyth Go is the latest of a sequence of closely related concurrent programming languages: Squeak, Newsqueak, Alef, Limbo and Go. Each one strictly followed its predecessor, they occupy a similar space (CSP-inspired concurrent languages), and all but Squeak have a vaguely similar syntax, perhaps suggesting gradual refinement and incremental evolution. I take a closer look, revealing their significant differences, especially in in type systems and run-time environments, reflecting the effect of different design choices to satisfy the requirements of a larger, surrounding system. Dr Charles Forsyth is a founder and Technical Director of Vita Nuova, which specialises in systems software and distributed systems. He is interested in compilers, operating systems, networking (protocols and services), security, and distributed systems and algorithms. He specialises in the design and implementation of systems software, from low-level drivers through compilers to whole operating systems. He has published papers on operating systems, Ada compilation, worst-case execution analysers for safety-critical applications, “resources as files”, and the development of computational grids.
