19:02 coppermine i wanna know what i need to use serial with it
19:16 coppermine is there a utility that cna convert an x86 binary file to arm binary?
19:45 Tom_itx rue_house
19:45 Tom_itx where did rue_mohr go?
20:42 rue_shop the desktop imploded last night, a video player did something nasty, still not sure what
20:42 home ew
20:43 Tom_itx imploded??
20:43 Tom_itx spend a good part of the day taking the washer apart
21:06 rue_shop what happened?
21:07 Tom_itx the bearing started making noise
21:07 Tom_itx didn't know what it was at first but it started getting worse lately
21:07 Tom_itx the mfg didn't have the bearings, they wanted to sell me the whole back end for $250
21:08 Tom_itx i said no thanks, not for a $10 bearing
21:09 Tom_itx i couldn't find any markings on the bearing so i'm kinda guessing on the size but i'm pretty sure i got it right
21:09 Tom_itx must be metric since the front one is
21:09 Tom_itx it had numbers on it
21:10 Tom_itx and there's only so many bearings that fit the criteria
21:10 Tom_itx so i'm getting some SS ones to replace em
21:19 rue_house what were the origionals?
21:22 rue_shop C R A P
21:22 rue_shop the boiler just totally blew all its lines
21:22 rue_shop good thing I had the 10lb extinguisher
21:22 e_shop looks at the
21:22 rue_shop damnit!
21:26 rue_shop this... brings to light a few issues....
21:26 rue_shop 1) hell yea, make sure a extinguisher is nearby, or
21:27 rue_shop 2) make sure there is a REMOTE auto suppression system
21:27 rue_shop 3) a line popping like that in a 5'x6' shed, would have been a problem on a NUMBER of levels
21:27 Tom_itx probably regular steel since the back one was all rusted
21:27 Tom_itx rue_shop
21:27 rue_shop a) all the control electronics are in there
21:27 Tom_itx you'd better be careful there
21:28 rue_shop b) if that shed filled with that much steam and spraying hot water, NO way to get into it
21:28 rue_shop I dont know how the hell much antifreze I just lost
21:28 Tom_itx it should self extinguish shouldn't it?
21:28 e_shop bangs head on
21:29 rue_shop with the blower off the fire is almost completely choked
21:29 rue_shop interesting thing, the safty release didn't go
21:29 rue_shop but I been using poly pipelines, two of them blew
21:30 Tom_itx maybe you should use hard lines until they exit the shed
21:30 rue_shop part of what I dont get...
21:30 rue_shop ok well the water temp was over 75c
21:30 rue_shop I wasn't running the auto temp regulator script
21:31 rue_shop its still all outside
21:31 Tom_itx you need a bladder tank to soak up some of the pressure
21:31 rue_shop but I'll need to make sure the safetys vent out of the shed
21:31 rue_shop its open
21:31 rue_shop there is no pressure
21:31 Tom_itx what blew then?
21:31 rue_shop ARG
21:31 rue_shop two poly lines split
21:31 Tom_itx oh
21:31 rue_shop and steam started rushing out everything
21:32 rue_shop I dont know what came first
21:32 Tom_itx the chicken
21:32 rue_shop ok well, there was gonna be a minor rebuild today that didn't get done
21:32 rue_shop so, I'll start a major one tommorow I suppose
21:33 Tom_itx seems today is problem day
21:33 rue_shop and suitable cleanup
21:33 rue_shop ? na
21:33 rue_shop one boiler explosion dosn't ruin my day
21:33 Tom_itx well neither does the washer but it sure took a while
21:34 Tom_itx and i get to do it all over when the parts come
21:34 Tom_itx i had to put it back together so i can use it
21:34 rue_house damn
21:35 rue_house its a good thing I put in all those shutoff valves
21:37 rue_house $sql = "SELECT * ";
21:37 rue_house $sql .= "FROM log ";
21:37 rue_house $sql .= "WHERE time > now() - reltime '1 hours' ";
21:37 rue_house $sql .= "AND time < now() - reltime '0 hours'";
21:37 rue_house $sql .= "ORDER BY sensor, time ";
21:38 rue_house SELECT * FROM log "WHERE time > now() - reltime '1 hours' AND time < now() - reltime '0 hours' ORDER BY sensor, time
