<fest> @esden: regarding the ram-pak design: for the differential clock, shouldn't there be a parallel resistor after the series resistors?
<fest> or is the differential clock connection provided "just in case" and single ended clock is what is supposed to be used?
<fest> also, the P/N for 1.27mm socket is probably incorrect, as it refers to a pin header. did you intend to use CLP-122-02-F-D-BE?

<electronic_eel> fest: the socket of the ram pak is a tricky thing, because it is planned to fit into the closed aluminium case. height is really critical there. so esden plans to use a custom header he found at some asian manufacturer. iirc he plans to sell the bare connectors in his shop once the ram pak is available
<electronic_eel> so i think he didn't really care about putting in a p/n which isn't properly selected yet

<fest> electronic_eel: got it, thanks. Ordered samples from samtec anyway, hopefully it'll fit (as I don't care for height)
<fest> icb: those seem to be out of stock anyway- any caveats for 3.3v hyperram?
<fest> as that's what I'm planning to try, assuming this monstrosity works at all: https://linx.wot.lv/selif/3cukopd8.jpeg
<d1b2> <icb> You would need to bypass the voltage regulator on the ram-pak board, but otherwise I think it should work. The 3.3v part is slower (100MHz instead of 166MHz)
<electronic_eel> fest: 3v3 hyperram has a higher current consumption than 1v8. so the 3v3 rail will see more load and the ram might get hotter. but i don't know if that will become a problem, i don't think it was tested yet.
<d1b2> <icb> Those antennae may cause some signal integrity problems, but worth a try since you already have everything
<electronic_eel> oh, yeah, the signal lines will emit more emi at 3v3 than at 1v8
<d1b2> <icb> Also be sure to feed 3.3v back to the Vref pin
<fest> icb: good catch, I also realized it seconds ago
<d1b2> <icb> Also, AFAIK only the hardware side has had any work so far. There's no support in the Glasgow software or gateware currently
<fest> yeah, that I've already prepared myself for :)
<tnt> In theory I should get a ram pak soon (I hope in time for the weekend) and I'll definitely try to push it to max freq, see how it works out.

<electronic_eel> whitequark: any plans to move the glasgow channel off freenode? I know you don't like sysadmin chores, but there seems to be a hostile takeover of freenode. and the new owner seems - sketchy at best. see for example marcans tweet here https://twitter.com/marcan42/status/1395053658182619137

<whitequark[m]> electronic_eel hmm
<whitequark[m]> at some point
<electronic_eel> currently a lot is still in flux of course, but i think planning a bit ahead won't hurt
<whitequark[m]> planning what exactly? once a clear successor network emerges we move there
<electronic_eel> registering channels for example. when a clear successor network is established, #glasgow might already be gone there
<electronic_eel> at libera.chat for example #glasgow already exists. op is "V". i don't know if it is someone from here who wants to cede control to you
<whitequark[m]> ask them
<electronic_eel> ok
<whitequark[m]> if libera.chat wants to be a successor network they're going to have to respect existing project allocations from freenode
<whitequark[m]> and not just have a free-for-all mess
<tnt> note that, if it turns out they don't cooperate, single # are reserved for projects and so you can contact libera ...
<whitequark[m]> yes
<tnt> (it's in their published policy)
<whitequark[m]> ah, even better
<electronic_eel> but their admin staff will currently probably be very busy. so going that route might take a lot of time
<tnt> yes probably ... they sure have a lot of work ahead of them in the coming days.
<ebb> from speaking to one libera staffer, handling requests like "can I have my channel back plz" are something they're expecting in the short term. registering as a project with libera, if that's chosen as the next place for Glasgow, would lodge that request nicely (and make sure it's not lost, since it's an email) IMO
<whitequark[m]> alright
<whitequark[m]> i'll see what i can do
<whitequark[m]> does matrix have a libera bridge yet
<electronic_eel> not sure about the matrix bridge. i hope they also remove the inactivity timeout requirement / policy when they create it.
<electronic_eel> i have contacted the op V at libera, but haven't got an answer yet.
<whitequark> anyone has opinions on logger domain?
<whitequark> libera.irclog.whitequark.org? liberachat.irclog.whitequark.org?
<whitequark> former seems nicer
<electronic_eel> yeah, i prefer former
<electronic_eel> i don't think several irc networks with "libera" and differing tlds will pop up
<Shiz> yeah libera seems good
<whitequark> mkay
