Potential trouble on this mail list - did this work ?
by Alain D D Williams 01 Dec '24

01 Dec '24

I have now moved it over. Potential issues: • The new IP addresses are 85.119.82.114 2a0a:1100:1012::114 You might see the old ones for the next ½ hour. • You might not see this email at all. This is one problem I have had on conversion -- sometimes.

Potential trouble on this mail list
by Alain D D Williams 01 Dec '24

01 Dec '24

I run this mail list. I am in the process of moving it to a new machine; at the same time I am upgrading from mailman2 to mailman3. mm3 is a pain (see below). I bridge all lists on the domain onto the old machine until I bring this across [ it has been happening for several days ] but things might break when I move this list. Apologies in advance if things go wrong. Currently running on mailman2, it was fairly easy to set up and get going; but the s/ware base is ancient (python2) and mailman3 does have some advantages (uses real SQL databases for user info, etc; one instance for all domains; etc). However the mm3 documentation is crap. Incomplete, wrong in places, assumes that you understand Django, etc, did I mention that it is incomplete ? Part of the reason for sticking with it is that I can import user rosta from mm2 to mm3 and also mail list history -- although it sometimes screws up. -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 https://www.phcomp.co.uk/ Parliament Hill Computers.

As I understand it, they have not yet been tested with Linux. that's massively incorrect. several versions of linux were installed and tested back in 2016. at least five OSes, plus initramfs's with barebones additional commands (a trick i learned from when i was doing HTC smartphone reverse-engineering) > What is the status of this project? it is, always has been, and will remain a community project where i expect the community - not myself with no funds - to take action. > Do you have a disk image? absolutely not. hosting of "images" is a major security risk and requires vast resources far beyond the meagre amounts of money available. there are however extensive build instructions to developers, on the wiki. > Do you want to/ should I tell people on the mailing list? all communication as a public FOSS project should be public and never to me personally, it has *always* been a given for the entire duration of this project that the very first thought you or anyone should have is to contact the mailing list, *not* myself, personally, directly, and certainly not privately [should be obvious what the exceptions to that are: admin, backers addresses and telephone numbers etc]. > Let me know your thoughts. i am so sorry to have to inform you that my ex-parter was a narcissist, embezzling money systematically, and her abuse caused me to develop chronic adrenal fatigue syndrome that resulted in me having at least two strokes. i had to report her to the police (twice) after fleeing for my life last year. she lied under caution when interviewed on the first assault: the second is still under investigation. in addition to that my former business colleagues turned out to be psychopathic, and by manipulating my family members and much more i ended up being assaulted, injured and almost killed by staff at a psychiatric "hospital" through neglect, forced-poisoning, and abuse. i have reported both to the police. as if that was not enough, i have been forced into the position of interacting with the UK NHS for the very first time in my life aged 54, which due to autism has gone so catastrophically badly that i am now up to a total of *EIGHT* abusive doctors to report to the General Medical Council to assess their fitness to practice medicine, and have the GMC's support to provide them with the meticulous documented evidence of abuse. in addition to that, NLnet has *also* been abusive, violating the Dutch Constitution, and has terminated funding. i am reporting them to the Dutch Equality Commission and when i am ready to do so (it is extremely risky for me, health-wise) i will be calling the police to report them for Defamation and Libel (criminal offenses in the Netherlands). i am now focussed exclusively on staying alive, and carrying out health research in order to recover. if i receive additional funds i can still run a team of people, however i will need help even finding that team, as i am in absolutely no health position whatsoever to go running around doing the work normally carried out by eight to ten people, as i used to do and a considerable number of backers assumed there was, all the time. l. > Kind regards > Helen Leigh > Crowd Supply > -- --- geometry: without it life is pointless the fibonacci series: easy as 1 1 2 3

hello helen i am top-posting to help preserve your message, i will start up my laptop to approve the membership (spammers) over the next few days. [i haven't provided details about what happened - i was almost killed by medical negligence that was initiated by DAVID CALDERWOOD, who manipulated members of my family including my brother DANIEL LEIGHTON who then in turn interfered with the process of extracting me from being tortured inside a psychiatric ward, by intimidating people helping me. no, not a joke: there are no euphemisms, untruthful statements or exaggerations in this paragraph.] leaving that aside. specific request: please can everyone *not* contact helen privately, this is and always has been a community project, i have just had my life devastated by NLnet seizing control of the running of Libre-SOC, where it took two weeks to retrospectively establish financial irregularites in their *private* communication with other team members, after they refused to consult me, the person with six years of administrative and financial records knowledge. it should be obvious we don't want that mistake repeated. so, for everyone who has contacted helen privately please forward your message again to the list: helen if you have begun speaking technically with them please forward those as well. yes it's a pain, but i guarantee if you're not strict about this you will get very quickly overwhelmed as you effectively de-facto "become" the project leader... ... with zero technical or historical knowledge... deprived of the bitter-experience-learned resources needed to manage any complex project. if you encounter *any reluctance even silence* please ensure you preserve those conversations - see three paragraphs below. so sorry to have to ask that. anyone and everyone who is on this list should know full well it is a FOSS Project and there should be no hesitation at all to speak freely and enjoy being part of the technical community. so, helen: if you are contacted privately please immediately and respectfully insist that they forward the message to the list, do *not* engage with them technically in any way (but don't be curt with them about it - best to refer them to this message). once they publish the message, *then* reply... on-list only. we need people to coordinate - helen you are not (sorry!) technically familiar with this project, and need help and guidance... *and so does everyone else*. the last thing we need is communications errors / failures / assumptions, and there is a perfect way to prevent that: *run as a community FOSS project* - i.e. *public* not *private* communication. bottom line, you may be given *wrong technical advice* and the only person properly qualified to identify and correct such: me and no other person. the exceptions i have already outlined previously (e.g. crowdsupply admin, orders admin, addresses etc) *except* a new one: if anyone feels intimidated *in any way* by the threats made by people who have been devastating my life and almost killing me multiple times (not a euphemism), please contact me privately in strict confidence as there is a crime of Perverting the Course of Justice under investigation, and any reluctance to speak freely and publicly without fear is *itself* crucial evidence.

What's new at the end of 2023?
by Franck Sinimalé 29 Nov '23

Hello everyone, The last news I read on this mailing list was saying that the next step for EOMA68 Computing Devices project was to boot an image. Since I'm not at this level of technique (very high for me), how could I help? Sometimes, relaunching the discussion is enough to get news and take a step ;-) Best, Franck

next step is a boot image
by Franck Sinimalé 23 Jan '23

23 Jan '23

Happy new year Arm-netbook ! Thank you Felix to make me recall this point of the project. I'd read, well I tried to... the "EOMA68-A20 2.7.4 preproduction board" page (thank's to Pablo I guess) and some other pages linked to. I'am sad to see that I'am under skilled to play with. In my old times I knew how to compile a linux kernel... but here it is a big step for me. Anyway, if some discussions are coming here about this topic, maybe I could see how to help, and learn more about this step. Does somebody has work in progress making this boot image and would like to share his experience here (or in an other way) ?

Fwd: Where are the 93 Computer Cards ?
by Franck Sinimalé 18 Jan '23

18 Jan '23

Hi all, Here is Chris's answer. Since I do not understand everything very well, I would ask you (Luke ?) what should I (we?) answer. My first idea could be : "Hi Chris, many thanks for you answer. Nice to read that you have some cards. Could you please send them to [this direction]. The next step that will be communicated is [this next step]." Ok, as the end of his answer suggest, I won't ask on mastodon or other people for now. I wait your answer (Luke ?) before replying to Chris. I don't know which direction to send cards nor what message to communicate about next step. Regards, Franck -------- Message transféré -------- Sujet : ...

We need an OS image and directions and probably some clear communications as to what to do next. If we're sending them to someone he should probably email me an address. It would also probably help if he email'd rather than asked other people to ask me where things stand. I have no idea other than this.
