[15:45:48] <jepler> cradek: it couldn't hurt if we published a correct spf record for (forum.)linuxcnc.org.
[15:46:17] <jepler> but the SMTP failure code says something about us being on a block list, which makes me think it is not about SPF, but about some kind of IP-based blacklist that is their own secret sauce
[15:46:18] <cradek> certainly
[15:46:37] <cradek> yep, bet so
[15:47:13] <cradek> they assume that only spammers use major hosting providers to send email; real people use 1 of about 3 "free" webmail services
[15:47:20] <jepler> and from a certain point of view, I bet not accepting e-mail from known by-the-hour cloud hosting services is a huge boon to users in terms of rejeced real spam
[15:47:56] <cradek> yes except for the collateral damage I'm sure it's great
[15:48:05] <archivist> usually the internet tells you how to get off those block lists

[15:48:29] <jepler> yes, a "just" system would have an effective appeals process to being listed
[15:48:51] <cradek> archivist: the well-known dnsbls usually have a process that's fine, but hotmail aka live aka whateveritis doesn't apparently use them
[15:49:15] <archivist> they probably read those lists
[15:49:37] <cradek> I doubt flo's ip is on them
[15:49:52] <jepler> if you find that we're on a particular list, let me know
[15:50:19] <archivist> the list companies let you check your ip
[15:50:33] <cradek> dnsbl.info shows all green
[15:51:14] <cradek> so we're not on 61/61 of the dnsbls they check
[15:52:12] <cradek> but it was generous of you to assume they're doing something sane :-/

[18:25:37] <jepler> wow I saw this in passing in a thread on -users, but the PCI standard permits a contact finish that has a durability of only 2 mating cycles, whith a durability half-life of one year when not mated, and the same for the connector
[18:25:45] <jepler> whith=with
[18:25:54] <cradek> that's horrifying
[18:26:37] <cradek> how can anything even work?
[18:26:49] <archivist> I have a video card that needs a jiggle every few weeks to keep one PC working

https://pcisig.com/sites/default/files/specification_documents/ECN_PCI_Connector_Finish.pdf
[18:27:29] <jepler> cradek: after 366 days new in box on a shelf, by the PCI standard it doesn't even have to
[18:29:26] <jepler> I haven't found similar information for PCI Express, but the first actual connector (receptacle) I found, molex brand, specifies durability of 50 cycles

[18:52:57] <PCW> we use 30 iinch gold plating on PCI/PCIE so the card is good for a few 100 cycles (motherboard socket is the limitation)
[18:53:23] <jepler> I'm happy to hear it
[18:54:03] <PCW> adds maybe $0.50 to the card so no big deal

[18:55:33] <jepler> PCW: hm2 ethernet receive timeouts -- should the default be a constant value, or should it be a fraction of thread period? I tested at 500Hz using period/10 and at least the system stayed stable with my changes..
[18:56:05] <jepler> .. but 200us is inappropriate if you are trying to run at 4kHz
[18:57:55] <PCW> yeah in terms of not skipping cycles if the dats is going to get there but is just slow, then something like 75% of the se4rvo period might make sense
[18:58:05] <PCW> data
[19:00:24] <jepler> anyway next evening I have free, I'll jumper a stepgen in quadrature mode to an encoder and set it up like a PID servo to see how it behaves wrt ferrror and pid. There's no "did the last read fail" output yet, so that's necessary before it's possible to add "PID hold"

[19:03:36] <jepler> cradek suggested the possibility that hm2 could instead lie about (estimate) feedback positions when a read is missed, instead of adding "PID hold", but I worry that would be more complicated overall (have to do it once for stepgen, once for encoder, once for resolver, once for absolute encoder...)

[19:05:31] <jepler> .. if you give up waiting too soon, there's another problem: next time you try to read a packet, you'll get the old one
[19:05:48] <jepler> I wonder if there's a syscall to discard any waiting packets, could do that just before send() of the read request

[19:09:00] <PCW> Right if theres a packet waiting at the start it should be discarded
[19:10:40] <jepler> > what to do about reads and writes with side effects (not idempotent), such as UART FIFOs, index/latch enable writes, etc
[19:10:48] <jepler> this is on my list as an unanswered question. do you have any thoughts?

[19:15:49] <PCW> writes need to be serialized to detect failure
[19:15:51] <jepler> .. if you set index-enable and next cycle it reads back false, you don't know if it was because index was already hit, or because the write got lost

[19:21:25] -!- automata_ has quit [Ping timeout: 268 seconds]
[19:21:31] <PCW> The loss of read data can be tackled a couple ways (requiring a commit in the write packet to update the FIFO pointers on read data is one)
[19:22:22] <PCW> maybe general commit for all read-side effects
[19:23:18] <PCW> not terribly worried about this yet as UARTs are not so widely used
[19:24:53] <PCW> or instead of commit a "restore pointers before last access cycle"

[19:45:22] <PCW> index is a bit of a special case, It may be possible to differentiate index events from write failures by using the just -once bit and latch-on-index bits
[19:45:24] <PCW> but a general write failure check is probably more valuable
