good old thunderhill, I'll be back soon :)
argh, all this for junkmail I never asked for :(
viewing platform for Mt St Helens
Museum of Aviation visible on the left of the runway
I had no idea the concorde had an anti tailstrike tailwheel
Their warbird collection was quite good and well layed out
the drone was supposed to launch with nukes in unfriendly territory
the smith tower is a nice view open later than the BOA tower and better view than the space needle
a seaplane was doing patterns with passengers on the nearby lake
cool shadow of our plane in the clouds with a rainbow around it. Neat!
little island just next to Lopez Island, pretty cool.
they have a catalog of local orcas
we saw a few orcas after a long boat trip
making sure my blood O2 saturation was still good at altitude
while in our way, the cloud made a nice wave, like surfing inside a crashing wave (this was just as we turned west)
we then got some nice VFR on top all the way back
and by Oakland, we got under the forming overcast that was starting to cover the bay (incidently, not Palo Alto yet)

moderately happy with the ride :)
ok, I won't quit my day job :)
this was a fun elevator ride up and down
The new 4D shooting show was quite fun
all these years, my dad liked cats, he just didn't know :)
nice dinner before visiting Disneyland
more meat parts than I know about
I went through my old pictures at VA Linux, and selected a few "best of" category.
It's a good trip in memory lane if you'd like to indulge :)
Beer Bashes:
Funny thing, I still have those two weapons in my cube:
Eh, we actually built and shipped stuff:
Oh yeah, that:
classic T-shirt:
Chris was always meant to be a penguin :)
Walt:
We're not alcoholics :)
IPO:
Can't argue with the logic:
Don Dugger, classic:
San, my man:
Getting hardware from the trash:
Allhands:
Funny slide:
new buildings:
who's the ice cream man?
Xmas:
Jeremy, you make me horny:
Steve, the master cook:
Chris Antilla/and Theresa Marie, Chili Judges:
For those who were there, our scooter and chair race around the track:
(I won the chair race by the way :) )
And in no time, Engineering was let go, Walt doing BBQ for us:
Josh, and his many hawaiin shirts:
We didn't quite come close:
Morale was high:
VA hemoraging staff:
Aaah, Leanne :)
You look good Steve:
Oh man, Brian was stoned big time
Oh, well, maybe it wasn't just him:
Hair to impress:
Jeremy, I think of you at night still, and I wish I didn't :)
Ah, our new CFO, she was cool, I liked her. Too bad she picked the wrong
company:
Yes, TM, you look good too :)
Classic Linuxworld:
And that's all folks, fun memories, good times :)
another nice view of the cemetary
they have a nice array of solar panels
why do people fill their garages with junk and park outside?
I calibrated the TTs vs the split 60CTs and the small CT-40s by comparing measurements of the same load
the 2 white boxes are the ECMs1240s, but I also have my older and bigger brand one power meters in there
the small donut CT-40s are great, they take no room at all
my source control system was _this_ big :)
software patents are both interesting and depressing
the questions on geeks vs nerds were a bit disappointing though
that was the linux pavillion at Comdex in 1996
ok, they have somewhat historical buildings :)
french dinner for our anniversary
no, I don't have a DSLR or even a tripod :)
this is what they look like when they're very old
this one landed on my pants :)
that was a few years ago, this is how cop cars looked back then
putting it on top of the dome must have been hard, it had to be helicoptered down
and yes, they have their own cop cars too
I got lucky with this one considering it was handheld from a moving boat
UV sensor in mostly water proof box
gets inside the attic through a water proof hole
the trick was not to bury the sensor too deep: just as deep as my grass roots
protecting the board from water
regular DS18B20 outside temperature probe in the shade
cat /etc/owfs/moisture/35\ Front_Lawn/current; echo -1.35875I looked at the range of values I typically get for full dry and full wet, and this is definitely sensor and board dependent. There is also the problem that the hobby-board design up to 2010/05, did not have a ground loop isolation transformer (without which the sensor would behave erratically as soon as you put it in the ground). Once you add the isolation tranformer, it does change the current values for dry and wet though, so each person may have to compute their own. Unfortunately I've seen my sensor briefly return values all the way to -2.55 instead of the typical wet -1.74
# 0.56625/0.5675 bone dry, but once got 0.335625. # glass of water yielded 1.74 but I've sometimes seen 2.555. What to use? my ($min, $max) = (0.33, 2.6); # value should be temp ajusted in an ideal world, but I don't have correction tables. $value *= -1; $value = $min if ($value < $min); $value = $max if ($value > $max); $value = (100 * ($value - $min) / ($max - $min));I've struggled on finding the upper value. First, I got -1.74 but eventually I sometimes got -2.55 out of the blue for a few samples, which yielded some clipping, so I changed the max value from -1.74 to -2.6 at noon on this graph, explaining the sudden dip. You can however you can see on the left the jump to 100% when the sprinklers were started: Despite the sensor being noisy, temperature dependent, and hard to calibrate, the overall graph is still useful enough to show whether your sprinklers are keeping the dirt moist enough, or if your overall moist is just going down (bad).
/configure --enable-debian
did the right thing for me, but you need to make sure you have the right headers on your system
I wrote this script, read_owfs that reads from an owfs symlink tree and generates a digitemp looking logfile so that it's easy to parse the logfile later with the same code regardless of whether you use digitemp or owfs to capture the data.
owfs with a hub is a bit "interesting" since you have to find your devices in subtrees, which is why I made a symlink tree to make my life easier. I setup a symlink for each hub port and a chain name to point to each of the 3 buses' AUX or MAIN branch. This is what it looks like:
/etc/owfs/bus1 -> /owfs/1F.F05005000000 /etc/owfs/bus2 -> /owfs/1F.E25005000000 /etc/owfs/bus3 -> /owfs/1F.E15005000000 /etc/owfs/chain1 -> bus2/main /etc/owfs/crawlspace_chain -> bus2/aux /etc/owfs/dining_chain -> bus3/main /etc/owfs/roof_chain -> bus1/aux /etc/owfs/humidity/56 Hall_Closet -> ../chain1/26.2E4DF5000000/HIH4000 /etc/owfs/moisture/35 Front_Lawn -> ../crawlspace_chain/30.131A62120000 /etc/owfs/temperature/11 Family_Room -> ../chain1/10.A8D1ED010800 /etc/owfs/temperature/12 Living_Room -> ../chain1/10.52D1ED010800 /etc/owfs/temperature/15 Garage -> ../chain1/10.2223EF010800 /etc/owfs/temperature/21 Attic -> ../roof_chain/10.5DE1ED010800 /etc/owfs/temperature/22 Roof -> ../roof_chain/10.94A2ED010800 /etc/owfs/temperature/23 Outdoors_Roof -> ../roof_chain/28.57B659020000 /etc/owfs/temperature/25 Roof_UV -> ../roof_chain/EE.E749CB010800 /etc/owfs/temperature/31 Crawlspace -> ../crawlspace_chain/10.F9F3EE010800 /etc/owfs/temperature/32 Outdoors_Crawlspace -> ../crawlspace_chain/10.D1D0ED010800 /etc/owfs/temperature/35 Front_Lawn -> ../crawlspace_chain/30.131A62120000 (...)This is how I start owfs and the xpl-owfs gateway:
