woah - just found a bug in apple imessages i think
if you use imessages on multiple desktops / iphones, all the messages are synced across them - ie: if you send me an imessage and i'm logged into my laptop and desktop, both of those devices will get the msg also
the boss sent me a photo last night of his new bmw and i got the photo on my home laptop and iphone - when i logged into imessages this morning at work, i got the message but not the photo
14:26
Ahhhh HOME laptop
14:42
What's an iMessage?
Apple's FU to sending a text message basically
same thing as a txt msg but over data and over apple's servers, not the phone companies
So it's different than a regular instant message in the same way a Podcast is different than an MP3
Apple must have studied Italian pasta making. Change one tiny thing and it gets a brand new name.

Slow news day.
Brain... mush... bla
^ that's what happens when I try to understand the openssl libcrypto api documentation... or lack thereof.
I don't understand crypto. That's why I use my own special Rot-13 implementation.
Double ROT13 is much stronger.
Welcome to Project Update Thursday
Sorry guys... no new projects this week
my home repairs this week consisted of soaking a shower head in vinegar
20:03
Pickling it?
@ChrisCudmore dissolving calcium deposits
our water is super hard
That reminds me that I need to flush my hot water heater and check the pressure on my expansion tank.
question, would I know if I had an expansion tank? I don't think I do...
I did repair my front door lock, graphite in a spray can is messy.
I bought a family pass for legoland.
20:05
An expansion tank is a couple gallon tank attached to a water line with only a single input
they are pretty obvious because most things on a water line have an input and output.
@BMitch gotcha
are we PUTing yet?
Yup, we're PUTting
@Matthew yes, you're up, 10' breaks left to right
20:08
I finally took some pictures of my low voltage work, in progress
now just need to upload them :D
damn onebox
tester101 on February 19, 2013

Private, older public, and some other water distribution systems may not require an expansion tank to be installed. This is because these systems may be considered “open”, since they lack pressure regulators and/or backflow preventers. Plumbing code changes intended to prevent the contamination of the public water supplies, have made backflow prevention a requirement in most current new builds. While this may be a good change for the water supply, it can be a damaging change to your plumbing system. …

THERE
@maple_shaft :)
is there a free uploader for SE?
other than the one for posts
imgur.com?
@Matthew you can upload them in chat with the upload button there
20:10
doh
of course I can
so I trimmed and wrapped all the coax, cat6 and speaker lines. Now I need to terminate them into the rack
still need to wrap the AV-specific cables
everything on SE should go through imgur.com, but you can go directly there and put up a set of photos to share together.
@maple_shaft yeah, I don't think I have one. will poke around, but I haven't seen one I've been all over under the house
@BMitch but then if he posts them I can't see them :(
cuz i.imgur is blocked here, but i.stack.imgur isn't :)
I like this new guy
@waxeagle Do you know how to solder copper pipes?
seems really knowledgeable and helpful
20:12
@maple_shaft nope :(
@waxeagle tell your office to stop blocking porn sites.
@BMitch that'll go well :(
@ChrisCudmore lol, we'll just say it's a ladder stabilizer bar. :)
@waxeagle You will need a propane torch, a copper T piece, and a copper tube cutter
20:14
uploading over mobile network is sloooooow
@maple_shaft does it have to go on copper? I've got all CPVC
@waxeagle they're installed with a threaded connection, I'm sure you can get an adapter for CPVC
@BMitch gotcha, not sure I really even need to add one. I'm guessing that I don't have a backflow preventer
20:17
@waxeagle if you have CPVC water pipes then please for the love of god don't take a torch to it :)
@maple_shaft lol wouldn't plan to :)
@waxeagle After you haven't run the water for a while, do you get an initial surge from the sink? Do toilets or showers leak frequently?
<---- not complete moron
If not, you're probably fine.
well if you had copper, you put a T, then fit a female adapter and solder that to the T
20:18
@BMitch no leaks. maybe a very slight surge
then with thread tape wrapped around the tank male end, you just screw it on tightly
@maple_shaft got it.
You're probably fine, but if they swap out your water meter for a new electronic version, then pay close attention to your valves, toilets, etc.
@BMitch will do
20:20
Just need to terminate the Cat6 wiring there and plug everything into the rack
@Matthew wut r u doin?
red/black wires... did you run a speaker system through the house?
He's running tubes for the internet.
@maple_shaft low voltage home run for remodel
@BMitch Yeah, those are speakers, 16 in all.
20:21
You can see the terminals in the rack photo
@Matthew you are a pretty cool guy
lol, my wife thinks I'm a giant dork
they looked a bit like cable jacks in the rack, I thought you were making a sports bar with 50 TV's
@BMitch The bottom 3U of the rack: top row is coax, bottom two are speakers
the blank row will be all the remaining cat6 -- there are 16 total -- the four on the left are the source wires from my demarcation box outside
@Matthew how are they controlled?
20:25
@waxeagle I don't understand your question
Speakers. How do you turn them on/off/volume
@Matthew ie you've got 16 speakers throughout the house, are they on a unified sound system or what?
There are 8 drops, each drop has 2 RG6 and 2 Cat6
Ah, the speakers.
@Matthew nah, that I understand :)
Many will go un-used. I wired the ceiling in the living room for 7 channels, each is terminated in a backer-box in the attick
three wires come out behind the TV, in the wall, 4 others in a plate on the back wall
2 in backer boxes in the kitchen ceiling
They'll all my controlled by separate remotes from my Anthem MRX300
7 channels on the Anthem, 2 on a separate power amp
I should have put an in-wall transformer couple for the kitchen but I didn't
I'm only going to use 9 of the 16 pairs
for now
20:28
@Matthew gotcha. full house audio is on my very long term to-do list
Yeah, mine too, but not in this house
full house audio isn't difficult if you are taking out drywall
@Matthew not an option for me any time soon :)
I want to replace that ProCurve switch though
it has a fan :(
20:42
Good afternoon gentlmen
Question on the mult speakers: How do you balance the impedence?
woah, howdy @shirlockhomes
@shirlockhomes They're all separate channels
Which is why there are 16 pairs
Hi Bmitch.... snow and rain here, tood day off
20:46
If they weren't, though, you use an impedance matching control
What kind of amp or whatever to drive 16 chans?
Some amps will, I'm only powering 9 though. 7 From my MRX300, and 2 using the MRX as a preamp with a separate power amp
I had to screw around with a 10 speaker system in a house. no manuals, told her to call an audio specialist. lol
For whole-house distribution systems you would use a speaker splitter with a high-power 2-channel amp
buy, ideally, you would get multiple channel power amps
For example, the UPA-700 will drive 7 channels with excellent quality
I found a distribution box hidden in the ceiling above a speaker
20:49
@shirlockhomes That's awful, but not the worst
thinking of doing something similar, maybe 8 speakers indoors and out
I worked on a system where they had twisted spakers together with wire nuts behind the drywall
u found it??? lol
little DW repair later lol
20:50
after their amp had burned out and a speaker blown
I just capped the wires in the blown speaker
I got a damaged speaker right now. Celtic Vega, can't find my guy that recones them
may have to attempt it myself
You can probably buy the cones from ebay
got a little carried away in my mancave
I bought part of my set before I Was married
I can get the cones, np. putting them in takes a little talent
20:52
I have resigned to the likely fact that I will never get to complete it
Paradigm Signature
parapigm from JBL?
WOWOWOWOWOWOWO
Those were the kick ass speakers of the 70's. still worth a mint today
@Matthew I should have done the same. Because after marriage, I'll never be allowed.
Maybe if I win the lottery
:D
looked at the link, not the same as the monster paradigms
back in 72 they sold for $3000 each
20:56
The S8's sell for about $4500 each
used to go the the audio store just to listen to them... Tommy from the Who was a fav. lol
They are among the most accurate and responsive speakers
yep, I believe it. That is top drawer stuff
The Sub2 subwoofer is $9k and it's recommended that you use a 220V supply
Don't think they are still connected to JBL james B lansing
heat your house with those
20:58
lol
9KW peak, 4.5KW continuous output
I'm real happy with my Boston A100's, mixed with the Vega's. can't run them over 30% with my Denon Class A, 55 watt RMS. way too loud
9KW!!!!!!!!!!! OMG
I like Bostons
I got 4 of them, love um
Nice and efficient
I love when people think they need 150 wpc
to run something like a Bose speaker
I stack a boston and a vega on each side
ya but today 150 watt is IC driven and meaqsured is some wierd way
21:01
Well, for most consumer amps it's a lie
I bet a 25 watt RMS is still more real power
The MRX300 I use can do 80 WPC sustained
and it's damned loud
but lets say I used Martin Logan electrostatics... well I would need more power
I'm half deaf now from playing my stuff so loud all these years lol
The sub2 needs all that power to drive 7Hz at meaningful levels
never have enough power! lol
Damn, can't hear that, just feel it
crack the foundation of the house!!!
21:04
then you will have to ask how to fix it. lol
that's crazy stuff
The demo at CES was amazing
they have perfectly phased the speakers in an opposing baffle so that the net at the device is zero
they set a martini glass on top of it, and the entire room is wobbling but the glass is perfectly still
damn customers keep calling, don't they know I took the day off. lol
I had a 8foot X 6foot picture window in my other house, and that thing would dance. always afraid it was gonna shatter someday
I can only play my stuff the way I like it when wife not home. Dig out the vinyl and party like a rock star. lol
21:22
My wife doesn't listen to music. She uses it as background noise.
So I'm stuck listening to music in the car.
hope you got a good system in the car. lol
Nah. No point. You can't get a good audio experience in a car no matter what. Waste of money.
true, but my Bose system in my truck sounds great
have mini concerts all by myself.
must be a slow news day in the DIY comunity
Nobody's doing anything at home.
nobody want to make fun of any of the questions lately? lmao
21:32
Not much snark worthy lately.
I got a bathroom and a kitchen to tackle very soon. waiting for the special orders to come it... both are horror shows
I'm waiting for a lottery win.
Then I'll get back to projects.
@shirlockhomes You missed my super-exciting low voltage rack :D
wish they would win the lottery too, low budget jobs
But I've spent 35k over the past two years.
21:33
I guess i did miss that one
went to florida for a couple of weeks, so missed alot
There's also a new member who has been pretty good
herrbag?
yeah
we're trying to get tile for the bathroom that doesn't cost $100 in shipping
35k? A mere pitance. lololololol good man
21:34
Well, the weeping tile and basement sealing was an unexpected 12k of that.
tile is heavy stuff
ya, hear ya... wet basements are expensive to do right
what's wet basement?
But we got a good company to do it. PROTIP: If you feed a Russian, he'll work twice as hard.
they cut a trough around the floor?
No. External
Dig out the foundation, new weeper, Hydraulic cement and repairs, Aquablock and delta board.
21:36
best way is external in a retrofit.
sounds like a good job
I'm trying to figure out the best way to insulate the house, but it has many different issues
how old a house?
for example, dose this sort of thing make sense?
conv framed or ballon?
21:37
But we had to get it done before I refinished the basement.
spray foam on the underside of the roofing plywood instead of on the floor of the attic
looks expensive!
When I looked at having my attic foamed it was about $1000 more than having new stuff blown in
But you get to keep all that storage space
faom is best, but most expensive
looks cool too
21:39
I did close cell spray in the basement. It was about $1600. Conventional was about $500 cheaper.
@shirlockhomes is it worth it to lay down batts in the attic if the exterior walls are brick - air- stud - plaster (NO insulation)?
yes, certainly is.
^semi-open wall during kitchen renovation
about 70% of your heat loss is thru the attic
brick walls are prime for foam
if the plaster is coming off
@shirlockhomes there's a company that will put holes in the mortar, blow it in from the outside, and then seal it back up
21:41
put R40 or more up there
that must be high density celulose. good stuff
that may be your best bet
I've done a lot of older houses that way
that way = ?
I sub it out to guys with the high pressure equipment
blow in the walls thru holes
can do inside or outside
inside the kitchen has an exterior wall that is tiled on the inside, so not so easy from the inside there
eiyther inside or outside, doesn't matter as long as the voids get filled well
homesulate.com/applications/brick-homes but sadly they are in dallas
21:45
I'm double brick, no insulation. Should I bother framing out the walls when I reno?
@shirlockhomes but you think doing the attic first is imperative?
yes I do
For insulation purposes, I mean.
wall loss is a fraction of attic/roof loss
heat loss
The attic's good.
21:46
and the attic may be the easiest one to do
most bang for the buk
buck
there's plywood nailed down across all the joists, so it's easy enough to just roll out some batts on it I suppose
and the attic tent thing
tent thing?
do you use it for storage?
the tent over the stair access
Yeah, we have a bunch of stuff up there now, it's quite a large area
so it is walkable with stair access?
You can't stand up straight in any part of it, but you can put tons of boxes up there
21:49
if you want to keep the floor open, you will have to do the underside of the roof
and that obviously increases the conditioned space of the house
and I would need to seal the gables
or give up some storage area and i's sugest pulling the plywood and gain that depth for insulation
R-42 is gonna be about 2 feet deep
Does it make sense to lay batts on only say, half the roof, and leave the rest for storage, or do you really need to do the whole thing to prevent gaps == air loss?
doing half is not gonna save you half. the heat or AC is goon leak in the areas not insulated. kind of a waste, in my opinion
It idea is to make a cold area above the house
did u say u were in Texas?
no
Washington DC
21:55
it's cold there. you gotta really go all , or pull the flooring and inslulate as much as you can to the ceiling drywall. if you got 2X8's you might get R21 in there
I wouldn't stop at a half job, it's like closing only one bedroom window.
put the plywood back over the insulated ceilings
yep, exactly
they're definitely not 2x8s
2x6 max R18
don't get me wrong, R18 is better than nothing
why can't they make stuff that insulates better in less space? it's 2013 already
21:57
If that 2x6 is over any significant span, I'd be careful where you store things up there
Foam does, but 2 to 3 times the cost
BMitch has a good point. 2X6, depending on span is not for heavy storage or walking
I was in DC a couple of weeks ago
damn GPS took us off the interstate onto Penn AVE. !!!!
where were you going to?
coming back to Maine from Fla
and you didn't say hi? I think most of us around here owe you a beer or two.
LOLOL thanks
22:01
You went back too soon, shouldn't have stayed in FL for a few more months.
we actually go to DC every year just for fun. I love all the stuff there.
next winter I'm staying there at least one month, maybe two
thinking of comming back to DC for the cherry blossoms
looks like you got some celulose already
22:03
get a better GPS before you do that, the crowds for the cherry blossoms are crazy.
that's in the middle of installing the bathroom vent fan
it is a loose fill, maybe R5 or 6 if your lucky
yeah, it sucks bigtime
I was there for the Rally to Restore Sanity. that was crazy
stayed at the harrington hotel, one block from the Mall
so, take out all the plywood, put in batts with vapor barrier, or just put in unfaced on top of all the plywood?
22:04
old dump, but really handy to all the stuff to visit
unfaced. do not put in vapor barrier
do you have soffit vents?
I stayed in some low-rent business suites hotel in Alexandria. Something like $120 bucks a night, 3 rooms, with kitchen.
@shirlockhomes no, just 2 gables
that is not bad at all Chris
Vapor barrier is hard to do at that point, you could try running a sheet of plastic over/between the joists, but otherwise, the place has lasted for that long without one.
did you go to the Rally?
22:06
No, this was a business trip.
of which one has the attic fan in it and the other has the vent from the bathroom fan going to it
Had to pitch to the American Psych. Ass.
How was that Ass.?
we don't use a vapor barrier unless there is really good vents in attic. can cause mold with all the humidity from the house
Smaller than you'd think.
22:08
I need a shrink, give me a discount?
Trust me. Shrinks are the least stable people I get on the help phone.
No patience whatsoever. Should I click this? This? THis? I'm going over here now? Whiy won't it work?
My wonderful cousin is a shrink, i love her to death, but she is certifiable
It seems like all the crazy people want to be a shrink, and all the crooks want to be bankers, and all the thugs want to be cops, what's up with that.
22:09
ummmmmm good observation
Hell, most tech people I know are luddites.
Late adopters.
my son is the ultimate techy geek
I'm still using XP at home.
You upgraded to XP already?
I've got XP at home too
22:10
Had too. Win98 stopped booting.
my son installed win 7 pro for me. naw na da na na..... lol
Nvidia geforce 6000 for life
do you have a crank start on that puter?
Aren't we all HOITY TOITY with our newfangled Graphics!
You can tell a good carpenter by how old his tools are, and a good techie by how long he's able to keep a computer working.
22:12
cmd is all I need!
my son interned at nvidia for 6 months. loved the work, hated the area
I actually had to downgrade the video card, I bought a 6800 or something, and it was drawing too much power, the computer would lock up every one in a while and it took me forever to track down why
ya tell me, all my tools are broken and need replacement, but i'm trying to retire
Luckily I was able to find an AGP 6200 card at microcenter last year
I was surprised
Ok, I think we're done PUTting...
22:15
my son still has my first puter with 1meg hard drive and like 12k ram. old packard bell. he likes to show his friends and play the old DOS games on it. Think it was a 286????
Thanks for joining this week's PUT
extended edition... since we started talking attics and insulation. :)
oh PUt This.. lmao Take care all

naa, you can still talk, I just didn't want to track the fun parts of the conversation.
See you all tommorrow.
22:18
bye Chris
@BMitch Are you still awake?
yuppers
I see we're getting more suggested edits from Mike/whatever he's calling himself: diy.stackexchange.com/review/suggested-edits/5550
yeah, I've been rejecting a bunch of them
might need to send him a mod message
But now that I think about it, there's not much you can do without the user merge tool :(
22:24
They should have left the merge tool and just redirected the request to SE so they could review it. Maybe cause it to generate a popup that the user had to respond to on their next login.
BTW, I found this book useful when I was learning my way around OpenSSL.
It's a little out-of-date now but still gives a good introduction to it
If wget can't do it, I leave it for someone else to do!
@NiallC. My problem is that I'm not doing SSL or TLS, and I don't want to store keys as individual files, my app is already doing the comm and I just want to encrypt part of the data messages, and keep keys in a local database, so I'm banging my head against the lack of API documentation.
My app includes a P2P messaging capability with an internal routing that allows messages to be bounced between a few nodes before it reaches the destination, so you don't want routing data encrypted, or decryptable by every node, you just want the embedded data to be secured from any man in the middle.
I'm pretty sure the wheel got reinvented a dozen times in my app, but it's been a fun learning experience.
22:39
Still think the book might be useful: Chapter 6, Symmetric Cryptography and Chapter 8, Public Key Algorithms
might have to see if I can find it in a book store, been spending way too much time on wikipedia lately making sure I understand all the terms
@NiallC. I sent the user a private message, and there are already several comments, so at this point I'm taking the view that all future invalid requests should be deleted until he learns how to use the site. You can lead a horse to water, you can shove it's face in, but after that, the beatings will continue until moral improves.
