online course in "working together with integrity"
by Luke Kenneth Casson Leighton 01 Sep '16

01 Sep '16

special circumstances compel me to forward this to the arm-netbook list as (with a little explanation) i believe it's relevant. below is a message from a friend of mine whom i've known for ten years, who has helped me out enormously. although the message below reminds me hilariously of much of the spam / advertising that i receive (and instantly delete or flag), it's only because i phoned her up to find out what it's about that i felt it would be important to (a) tell people that i'll be participating (as part of the campaign ongoing reporting) but also tell people about it so that if they also feel it's something they'd be interested in they can also join in. in speaking with sarah she said that she's collaborating with a couple of other people she's met recently, to work on a new course, teaching and coaching people to collaborate wisely and with integrity to fulfil specific far-reaching goals. now, as many people in software libre collaborate together, and they respect the principles of the four freedoms, and their work has far-reaching strategic consequences, it *should* resonate very strongly... but in 20+ years of working with free software i can honestly say that i know of absolutely few software libre developers who have actually *declared* - publicly - an intent to go to *workshops* to improve their effectiveness! i know of several charters (debian, apache, devuan are developing one, parabola are working on one) but i don't know *anyone* who's gone, "hmmm, i have absolutely no clue how to run a successful group collaboration, i have no idea what works well... let's go to a workshop to find out!" that i include myself in that is something i find to be hilarious. so. anyway. yes. i'll be attending this workshop. please don't tell dr stallman that i'll be installing proprietary (non-free) software to participate. there are international dial-in numbers to join in (voice-only, obviously). if it resonates at all with anyone here, feel free to sign up at your own responsibility and see what it's about. l. ------ A Little Understood Fact About Purpose <http://sarahmccrum.us5.list-manage.com/track/click?u=9a87be132b86a04f9be84e…> <http://sarahmccrum.us5.list-manage.com/track/click?u=9a87be132b86a04f9be84e…>Where can you find your purpose? Is it a mission you’re supposed to complete? Is it finding the right job? Is it following your passion? Suppose you don’t feel passionate about anything? Or you’re not doing quite the right job? Or you have no idea of your mission, even if you feel there is one out there somewhere for you? What are you supposed to do then? You can wait, but for how long? You can try really hard to find it, but do you even know where to look? You can ask someone else, but how much do they really know about you? And then you feel off track, or that vague sense that you’re supposed to be doing something else, but you don’t know what it is. You’re on a search for purpose. The ironic thing is that the more you search for purpose outside of yourself the more elusive it becomes. I was working with someone who had a very demanding job. She felt uneasy about the fact that she wasn’t doing her purpose, but had decided she’d have to wait until she retired because she needed the money and didn’t want to give up her job. When I questioned her more deeply about what her purpose was, she said she wanted to experience inner peace and share that with other people. It seemed to me that her highly demanding workplace was the perfect environment for her to develop inner peace. And her role included responsibility for the wellbeing of the entire office, so she was surrounded by opportunities to share any peace she could experience. This is so often the case. When you’re looking for the right time or opportunity to do your purpose you’re looking in the wrong place. Your true purpose is always something you can do right now. Whether you’re fundamentally about love, freedom, wisdom, peace, joy, potential, creativity or something else, these are all qualities you can take with you to the best and worst job. You can practise them whether you have a passion or not. The interesting thing is that the more peace, joy or freedom you experience the better jobs you find, the more passionate you become and the more you discover your mission. So it all adds up in the end. I*’m running a free online workshop about purpose this weekend on Sunday at 9am (Pacific time) which is 5pm (UK time). You can sign up for it **here.* <http://sarahmccrum.us5.list-manage.com/track/click?u=9a87be132b86a04f9be84e…> *Sarah McCrum Speaker, trainer, mentor*

ESD protection
by Vincent Legoll 01 Sep '16

01 Sep '16

Hello, I just wanted to raise awareness of problems potentially linked to lack of ESD protection on some boards. I'm no EE, and my electronics background is near zero, so I cannot asses if EOMA68 boards (CPU & docks) are affected or not... You can have a look at this report: http://www.orangepi.org/orangepibbsen/forum.php?mod=viewthread&tid=644&extr… WDYT ? -- Vincent Legoll

EOMA68 Power Specifications
by Joseph Honold 31 Aug '16

31 Aug '16

I'm reading the eoma spec at elinux and there is limited information regarding the power requirements. It states "*a maximum of 3.5 watts should be respected" and "**Type II Cards should not exceed an average of 3.5 watts power consumption" and "*must adjust accordingly and stick within the 4 watt heat dissipation budget". Is there a minimum requirement for supply current that must be available to the cpu card from a housing/device/socket for compatibility with multiple cpu cards (3.5 or 4 watts)? What is the A20 cpu card power consumption (average/peak)?

Keyboard
by Vincent Legoll 29 Aug '16

29 Aug '16

Hello, First, congrats on the campaign success ! I tried searching the ML archives & rhombus site, but couldn't find it. Is the laptop's keyboard only option the Keyboard: Chicony P/N MP-03756GB-5287. Or can a backlit one be substitued easily? I.e. No other HW redesign... Or maybe the laptop case can be modified to allow placement of a few leds around the screen that would get light on the keyboard. I had this on an old T42p and it was better than nothing. That would make the laptop better suited to night use. Wdyt? -- Vincent Legoll

RGB/TTL interface
by Louis Pearson 28 Aug '16

28 Aug '16

I have been trying to figure out how exactly the RGB interface that the eoma-68 standard supplies works. Or, in other words, what you would need to be able to connect it to a screen. The info that I have managed to find makes me think this would connect directly to a LCD or TTF screen's ribbon cable. Is there a description of what is provided with this interface somewhere?

Will EOMA68-A20 be sweatshop-free?
by Sam Pablo Kuper 27 Aug '16

27 Aug '16

Let me start by saying I realise that Luke (& undoubtedly others) have already put a *lot* of sweat into EOMA-68, and will likely be working some very long hours in the months ahead. I also realise that even with the tremendous success of the first CrowdSupply round, the volume of production is minuscule compared to Apple, Acer, Dell, etc, and hence also the risk of exploiting contracted workers will be lower - even if only because fewer workers will be assembling EOMA68 hardware. Nevertheless, low resource use; reusability; repairability; RYF compliance... these are necessary properties of an ethical computer, but not quite sufficient ones. Avoiding slavery, indentured labour, etc, and ensuring electronics supply chain workers are able to live decent lives, is surely an equally important part of building ethical computers. With that in mind, are there any plans for Rhombus Tech or other EOMA-68 producers/partners to work with organisations such as these? http://electronicswatch.org/en/ http://chinalaborwatch.org http://www.sacom.hk http://www.ilo.org/global/about-the-ilo/lang--en/index.htm I suppose that the ideal thing would be for some sort of ethical sourcing requirement to be written into the EOMA-68 standard ;) - spk

Wikipedia article
by Sam Pablo Kuper 27 Aug '16

27 Aug '16

Congratulations on exceeding the funding threshold! EOMA68 now has a stub-class article on the English Wikipedia. It could do with being expanded, with references to reliable sources as per Wikipedia policy. Probably Luke shouldn't do that, to avoid conflict of interest, but it would be great if others chipped in with the effort :) https://en.wikipedia.org/wiki/EOMA68

WonderMedia SoCs
by Dima Krasner 27 Aug '16

27 Aug '16

Hi everyone, I'm Dima (more info about me at dimakrasner.com) and I'm new here, so ... hi. For years I've been following the ARM scene, since I'm very interested in libre hardware projects. Chinese ARM netbooks with WonerMedia chips (8850, 8880, etc') are very common in sites like AliExpress and Ebay and they're pretty darn cheap. Performance, RAM amount limit and decoder performance should be reasonable, compared to other cheap ARM boards. I see the WM8950 has been evaluated, but the wiki doesn't say what's wrong with it. As far as I can tell it's yet another Mali-400 board. Upstream kernel has partial support for newer WonderMedia chips, but there is a small community at https://groups.google.com/forum/#!forum/vt8500-wm8505-linux-kernel and as far as I know older ones (like the 8650) should work to some degree with current upstream kernels, some rotten code floating around multiple kernel trees needs to be upstreamed (possibly, after refactoring) and there is an old, public U-boot fork, at least for the 8650. As far as I see, these are technical ecosystem issues that can be solved by a small group of volunteers with kernel, upstreaming and embedded development experience, even without any vendor support. Therefore, if the 8650 still under mass production, it could be an EOMA68 candidate. Although I understand while the A20 is preferred to WonderMedia chips (it makes life easier on the software front, probably more than any other non-x86 SoC), I wonder, what makes them unacceptable in RYF hardware? Is there any technical issue that I've missed? Cheers, Dima
