I recently switched to a gas powered on demand water heater in our house and love it. It takes a little while longer to get hot water to the tap, but it never runs out. On top of that it is more efficient, uses gas vs. electricity and frees up space in my basement because it is on the outside of the house. The downside is that installing it wasn't easy (it was part of a larger remodel) as it involved water, gas and electricity to be routed to its new site. - Joe Beda

I'm thinking a combined-cycle gas turbine with heat recovery steam generator should do the trick. - Gabe

I think the trick is that you'd have to get the post office to segregate the junk mail from the mail you actually want (like credit cards with new expiration dates). - Gabe

I lalready can................and I only ordered from one.........and they keep coming even though they say this may be your last one................. - VAL D.

now sort of a thought there Gabe............the post offices should use junk mail to heat the post offices - VAL D.

catalogchoice.org actually works - Peter Chane

What's a dry fluid? - Gabe

Dry cleaning isn't dry. - Rochelle

Then shouldn't it be called "wet cleaning"? - Gabe

It seems like it would be difficult to brush an infant's teeth. It's hard to get her mouth open to insert food, let alone to do something she obviously won't like. - Gabe

Hard, but not impossible :D You just have to be quick and ruthless. - Victor Ganata

For the first few teeth, it's more a ritual than anything. Thankfully the first ones are all in the front. - Matt Mastracci

Surely somebody on FF knows this! - Gabe

You need to place your request in the form of "DO ANYBODY NO" to get a response. - Louis Gray

Hah! I'm not sure, but you could try asking Chris Baskind. He might be able to hook you up with someone who knows. - Rochelle

http://efdl.cims.nyu.edu/project... http://www.gorhamschaffler.com/humidit... http://adsabs.harvard.edu/abs... hope that answers your question - chaz2b

chaz2b: Thanks, but neither of them seem to have what I want. The efdl link has variables labeled rh, pa, and Ta. I can infer that they mean rh, pressure, and temp, but it doesn't say what units they're supposed to be. The gorham link tells how to get absolute humidity, not specific humidity. The adsabs link seems to have differential equations, but nothing I can use. - Gabe

Does this help? http://www.engineeringtoolbox.com/specifi... - Greg GuitarBuster

I can't see what chaz2b provided. Here's a chart that might be of use: http://www.tis-gdv.de/tis_e... - SuezanneC Baskerville

Greg: that link requires knowing the density of water vapor and air. All I have is a weather report. - Gabe

SuezanneC: your link has absolute humidity (g/m^3), not specific humidity (g/kg). - Gabe

You say that as if that means it doesn't answer your your question, but I"m not sure that is the case. You ask for the mass of water vapor in a volume of air, which seems more closely related to grams per cubic meter than it does to grams per kilogram. Here's another link. http://forum.onlineconversion.com/showthr... . Also, when people take the time to try to solve your problems for zero dollars per hour, a thank you would be appropriate. - SuezanneC Baskerville

Also you might try searching usenet. - SuezanneC Baskerville

try this http://www.cactus2000.de/uk... - jamar78

Thanks, jamar78, that's basically what I was looking for. - Gabe

SuezanneC: thanks for the help, but I wasn't looking for somebody to do research for me. Google was supplying a bunch of links that didn't answer my question so I just figured that there would be some engineer who would know the answer off the top of their head. - Gabe

If you have a psycometric chart handy, you can read it off that: http://en.wikipedia.org/wiki... - Clare Dibble

Clare, I was hoping you would just give me an equation. It's hard to write a computer program to read things off a chart. - Gabe

http://www.gorhamschaffler.com/humidit... - J. Abdul-Qahhar

The problem is that you need to know the total amount of water that air will hold at a given temperature and pressure. After you have that, you only need multiply that by the relative humidity to get the specific humidity. Water and air is a very common system, so the saturation pressure and temperature are compiled for a very wide range. It's hard to fit an equation to such a wide range, so people usually look it up in a table or fit an equation to their desired range of temperatures and pressures. - Clare Dibble

Update: if you are near ambient temperatures and pressures, you can assume the ideal gas law and use Antoine's equation to calculate saturation. The coefficients are available here: http://webbook.nist.gov/cgi... - Clare Dibble

You guys are geeks - Becca

Five little ducks went out one day, over the hill and far away. Mother duck said, "Quack! Quack! Quack! Quack!" But only four little ducks came back... - April Buchheit

Did you guys do this?! I love it. - Becca

Make way for ducklings! The idea just popped into my head - so I carved it. - Maggie

maybe you should call the front desk and ask - Maggie

Depends.. What kind of candy bars are they? - Alex

There's a Snickers and a 3 Musketeers. - Gabe

$3.50 - Jordan Hofker

$1.75. - Akiva Moskovitz

$51.70 - Snipergirl

1000 pesos. - imabonehead

$4.99 - Gary Burd

$6.50 - Eric Logan

$6 - Jason Huebel from iPhone

It was $1, and was one of the smallest bananas I've ever eaten! Of course the receipt was a whole 8.5x11 sheet of paper. In a grocery store you can probably get multiple pounds of bananas for $1. - Gabe

it's 45 cents per pound in my local Wal-Mart... - Philippe

Whole foods actually sells it for $0.60 sometimes... So it is not terribly off :) - Bindu Reddy

I saw a sign on my way to the hospital today that said "Pop can drive this weekend". - Gabe

Collecting donated empty soft drink cans for recycling money - it's a fundraising activity, typically used by secondary schools and kids sports teams/social clubs. - Micah Wittman

It means your father is capable of operating a motor vehicle. - MicahBear78

OR... he thinks he can still drive but they never renewed his license. - Micah Wittman

It turns out that Micah is right about this one. - Gabe

Be more specific. - MicahBear78

Get a quality disposable. That's all I use anymore. - Cristo

What is a quality disposable? - Gabe

I bought a massive pack of disposable razors (BumpFighter brand by ASR) on Ebay about 2 years ago. I'm still not out of them. :) - Ha3rvey (Free hugs!)

The one with the most blades. Gillette Mach 7 or something. - Rodfather

I like the Mach 7. I've been using mine for several years. Just buy the disposable blade thingies and you keep the handle. Works great. Nary a knick on my face. - Jason Huebel

Those disposable cartridges cost something like 10 times as much as regular razor blades. And I'm guessing they don't last as long. I can't imagine using up $20 worth of razor blades in a year. How many dollars per week do those fancy cartridges cost? - Gabe

I don't use cartridges, and I'm too lazy to go figure out exactly what I use. I think they're made by Gillette. They have plastic handles and blades built together. I think they pivot and have 3 or 4 blades. I only change to a new one about once a month, if that. I don't spend much time worrying about he cost of razors though. ;) - Cristo

So the consensus is nobody knows where to buy razor blades so you have to use a cheap, crappy disposable or expensive cartridge-type razor instead of the good yet cheap razors. - Gabe

And nobody should if malware writers have their way. Data is code!! Err... - George Burgyan from iPhone

Most software projects have two repositories of information: a code repository and a data repository. The exact same information can be called code or data depending which repository you put it in. By the way, you get more answers on FriendFeed if you write DO ANYBODY NO. - Bruce Lewis from fftogo

code:spaghetti::data:meatball ... (going to have some ravioli for lunch now ;^) - Dan Freeman

Code is always data, and data is sometimes code. - Cristo

Cristo: what sort of data is not code? - Gabe

Gabe, the kind for which there is no current machine or virtual machine to execute it. Of course, the thesis degrades as the definition of code does. If any code that doesn't do anything useful (immediately faults or throws an exception) is deemed to be code, but just bad code, then of course all data is code. Similarly, if an area of memory that holds data is what is being talked about, and there is a way to change that memory to some different data, then of course that data could be loaded with code. - Cristo

To me, data is the result of something -- observation, calculation, measurement etc. Code is the instructional manipulation of data - Shey, Jamaican of FF

what I recall from OS theory class is "different segment" - winterismute

Which segment does Python code run in? - Cristo

Sure, you could say that a text file is clearly data, but isn't it really code instructing the text editor what to display? - Gabe

It depends on the context, and on which definition of "code" you are using. Program code is the instructions - the program itself - while data is anything that gets fed in to / spewed out of the program. Of course, your data can be more program code, or it could be encrypted text (also called "code"), or perhaps a set of dialling prefixes ("codes"), or it could even be a string of... more... - Slippy "Threadsbane" Lane

Gabe, Checkmate. Data is always code (for a text editor). :) - Cristo

*Ahem* I think you'll find that's NOT checkmate. I shall counter with "Code is always data (for a C compiler)". Bishop takes King's rook's pawn, and I think you will find, sir, that there is your checkmate. :-) - Slippy "Threadsbane" Lane

Code is an algorithm and the data is the result of that algorithm. - ashish

Slippy, my response was to Gabe, and code wouldn't be data for a C compiler if it was Python code, unless a bunch of random syntax errors would be the result you were looking for. - Cristo

Yes, I often annoy people by joining in chess games as I pass by and claiming that every move I make is checkmate, despite not even knowing what the little horsey pieces are called. It's the intellectual equivalent of shouting the wrong punchlines at people who are telling jokes. Not that I'm claiming to be intellectual, of course. - Slippy "Threadsbane" Lane

But actually, Python code would still be data to a C compiler - it would be meaningless data that it couldn't compile, but data nonetheless. King's horsey takes Jack's prawn. That, I believe, is a Royal Flush. Game, set and match me, I think. - Slippy "Threadsbane" Lane

Slippy, see my earlier comment about the thesis degrading. - Cristo

in a more esoteric sense, one might entertain a general equivalence between some data and the simplest code which could produce that data (ala Kolmogorov) ... - Dan Freeman

In terms of DNA, RNA, and protein sequences, there isn't really a difference. - Victor Ganata

Cristo: Careful, you are in very real danger of taking me seriously. I am merely stringing words together for fun. - Slippy "Threadsbane" Lane

Slippy, you're doing a good job. ;) - Cristo

Because they hate you - Becca

Or they hate their users: "Take the exit onto I-80 W toward Lowa. Take exit 151A on the left to merge onto I-57 S toward Memohis". I'm pretty sure Illinois's highways signs don't actually point to Lowa and Memohis. - Gabe

I wouldn't be surprised if they do Gabe. I know that there are plenty of signs on I-94 in Michigan which say either Detroit or Chicago. - Robert Felty

Rob: I'm going to guess that all of the signs around to Chicago point to actual places like Iowa (rather than Lowa) and Memphis (rather than Memohis). - Gabe

I thought you had made those typos. Now I see what you mean. - Robert Felty

Here's the putative trip: http://maps.google.com/maps... - Gabe

I need them so that I can confirm the request in a timely manner. People seem to get upset if you wait a week to confirm their friendship. - Gabe

There must be a lot of people upset with me. - Cristo

So if you only log into Facebook every six months or so... hmm. - Matt Cutts

Happened to Twitter emails for me. - Josh Haley

I log into Facebook whenever I remember to. Sometimes it's multiple times per day, other times it's every few weeks. - Gabe

Hazel is amazingly cute!! - Robert Felty

Rob: She's not really that cute in real life. The camera adds 15 pounds of cuteness. - Gabe

I love her coat! - April Buchheit

Hazel has lots of cute outfits. Be sure to look at the whole set! - Gabe

The skeleton outfit is a great idea. Too funny. Dig the tiger too. - Louis Gray

So cute. :) - Ayşe E.

Wait a sec, Rachel. I don't think that skeleton outfit would fit you. - Gabe

Tiger costumes? I thought those were for weddings ;) - Clare Dibble

The tiger costume was a garage sale buy that my mom made. It just barely its her now, so there's no way it would make it to Halloween. I bought the pumpkin costume for her and then I found the skeleton costume at Target (which I couldn't resist). - Maggie

What is it with Gabe taking pictures of the women in his life with their tongues sticking out? (look at picture 100_6511 http://www.flickr.com/photos...) - Robert Felty

Rob: Clare got me started! - Gabe

Here are some before-and-after photos: http://www.autoblog.com/gallery... - Gabe

Aw, they wasted a 59 Chevy? - Andrew C
